Description

[Detailed description of the invention] [Industrial field of application] The present invention is a multiplexed type that tightly tightens and holds two objects to be tightened, such as split protective sleeves for communication cables, at multiple consecutive locations. This relates to a tightening device.

[Prior Art] A conventional tightening device disclosed in Publication of Utility Model Publication No. 56-46442 has a hook link having a hook portion at its tip that is hooked on the engaging portion of one object to be tightened, and a hook link provided on the tip end of the hook portion to be hooked on the engaging portion of one object to be tightened. A mounting board is fixed to an object to be fastened, the base end is pivotally connected to the bearing plate part of the mounting board by a first pivot, and the intermediate part is connected to the base end of the hook link by a second pivot. It consists of a pivotably mounted operating lever, and when two objects to be tightened are mutually tightened, the second pivot is positioned on the side of the other object to be tightened with respect to the straight line connecting the hook and the first pivot. be.

[Problems to be solved by the invention] In this conventional device, the hook link and the operating lever are connected to the mounting board fixed to the object to be tightened via the first pivot shaft and the second pivot shaft. When the clamping device is unclamped and the clamped object is removed for the processing operation, all components of the clamping device remain attached to the clamped target. Therefore, if the object to be tightened falls from a high place onto the floor or is thrown roughly, or if it collides with other equipment while placed on the floor, the tightening device may become distorted or deformed. may be damaged.

In addition, when the main body and lid of a transportation container that undergoes a lot of wear and tear are to be tightened, with a fixed type of tightening device like this, when the transportation container is discarded, the still usable tightening device must be disposed of as well. Since there is no gain, there is a lot of waste.

Therefore, the purpose of the present invention is to be able to remove the entire device from the object to be tightened when the object is unfastened, and to be able to perform tightening at multiple consecutive locations. It is an object of the present invention to provide a non-fixed type multiple tightening device that allows this multiple tightening operation to be performed easily.

[Means for Solving the Problems] The non-fixed multiple type tightening device of the present invention will be explained below using reference numerals in the attached drawings. 4
are inserted in series into each tip 21 of the object 1 to be tightened.
A hook bar 3 that is simultaneously hooked on a plurality of engaging portions 2 provided in parallel to the hook, a plurality of tension links 8 arranged in parallel corresponding to the hook links 4, and a tip of each tension link 8. It consists of a pressing rod 7 that is inserted in series through the portion 22 and simultaneously pressed against a plurality of engaging portions 6 provided in parallel on the object 5 to be tightened, and is connected to the proximal end portion 9 of the corresponding tension link 4. When the base ends 10 of the tension links 8 are individually connected by the pivots 11 and the objects 1 and 5 to be tightened are mutually tightened, the pivot points are 11 is positioned on the side of the object 5 to be tightened.

[Operation] A single hooking rod 3 is simultaneously hooked on the plurality of engaging portions 2, 2 of the object to be tightened 1, and a single pressing rod 7 is connected to each of the plurality of engagement portions 2, 2 of the object to be tightened 5. After pressing the parts 6 at the same time, each of the plurality of tension links 4 is tightened against the objects 1 and 5.
When pushed individually toward , each tension link 4 rotates around the engagement part 2 , while each of the plurality of tension links 8 rotates around the engagement part 6 and are connected by the pivot 11 . The tension links 4 and tension links 8 that have been tightened together approach the objects 1 and 5 to be tightened.

When the pivot 11 is on the front side with respect to the straight line connecting the rotation center of the hook rod 3 supported by the engagement part 2 and the rotation center of the pusher rod 7 supported by the engagement part 6, there is no packing between the objects to be tightened. The rotational operation of each tension link 4 and tension link 8 is resisted by the repulsive force caused by the elasticity of the member and the object to be tightened and the elasticity of each hook link and tension link themselves.

At the moment each pivot 11 crosses the straight line connecting the rotation center of the hook rod 3 and the rotation center of the push rod 7 toward the object 5 to be tightened, the repulsive force pushes the tension link 4 and the tension link 8 in the direction. This is converted into an urging force that causes the object to rotate, and each tension link 4 and tension link 8 rotate vigorously, and the base end 9 of each tension link 4 collides with the surface of the object 5 to be tightened.

This completes the closing and tightening of the objects 1 and 5, but the repulsive force is used as a rotational moment in the direction of pressing the base end 9 of each tension link 4 against the surface of the object 5. Therefore, this tightened state is maintained accurately, and the tightening is not unintentionally released due to vibrations, shocks, etc.

When the base end 9 of each tension link 4 is pulled up toward you against this rotational moment, the tension link 4 rotates in the opposite direction around the hook rod 3, and in conjunction with this, each tension link 8 is pushed. It rotates in the opposite direction around the abutment rod 7. At the moment when each pivot 11 crosses the straight line connecting the rotation center of the hook rod 3 and the rotation center of the pusher rod 7 toward the front side, the force in the compression direction acting on each tension link 8 and the force in the tension direction acting on each tension link 4 Power disappears together.

Therefore, the hooking engagement between each engaging portion 2 and the hooking rod 3 and the pressing engagement between each engaging portion 6 and the pressing rod 7 are simultaneously released, and each tension link 4 and tension link 8 are tightened. Can be removed from objects 1 and 5.

[Embodiment] In the illustrated embodiment, the objects 1 and 5 to be tightened are split protective sleeves that cover the connecting portions of communication cables, and a packing member 12 is attached to the joint end surface. The engaging portion 2 consisting of a band-shaped raised portion is integrally molded on the surface of the joint end portion of the object 1 to be tightened.
An arcuate receiving groove 14 is provided on the end surface of each of the engaging portions 2, 2, which protrude parallel to each other, on the opposite side of the joint surface 13. Similarly, the engaging portion 6 made of a band-like raised portion is
It is integrally molded on the surface of the joint end portion of the object 5 to be tightened. Each of the engaging portions 6, 6 protruding parallel to each other has an arcuate receiving groove 16 on the end surface opposite to the joint surface 15.
is provided.

The single hooking rod 3 inserted through the side plate portions 17, 17 of the tip ends 21 of the plurality of hooking links 4 is constituted by a round bar, and the hooking rod 3 is inserted into each of the receiving grooves 14 of the engaging portion 2. mated to. A single pressing rod 7 is inserted through the side plate portions 18, 18 at the tips of the plurality of tension links 8, and the pressing rod 7 is inserted into each receiving groove 16 of the engaging portion 6

Since the tightening device is accommodated, the entire tightening device fits well, and no excessive protrusion is produced on the surface of the object to be tightened. An escape recess 20 into which the push rod 7 enters is provided in the middle of the side plate 17 of each tension link 4.

In this example, since the object to be tightened is a cylindrical body, each tension link 4 is formed in a curved manner. can also be formed into a curved or straight shape.

In the embodiment shown in FIG. 4, the operating arm section 19 is provided by extending the base end 9 of each tension link 4 in the opposite direction to the hooking rod 3, so that no force is applied to the tip of the operating arm section 19. By applying this, individual rotation operations of each tension link 4 can be performed relatively easily.

[Effects of the invention] As described above, the non-fixed multiple type tightening device of the present invention has the ability to hook the hooking rod 3 inserted through the tip 21 of the tension link 4 to the engaging portion 2 of the object 1 to be tightened. ,
The pressing rod 7 inserted through the tip 22 of the tension link 8 is pressed against the engaging portion 6 of the object 5 to be tightened.
The pivot 11 that connects the base end 9 of the tension link 4 and the base end 10 of the tension link 8 when the tension is released is the hook bar 3.
The hooking engagement between the engaging portion 2 and the hanging rod 3 and the pressing engagement between the engaging portion 6 and the pressing rod 7 are immediately released as soon as the straight line connecting the pressing rod 7 and the pulling rod 7 is crossed. 4 and the tension link 8 can be immediately removed from the objects 1 and 5 to be tightened. Therefore, the object to be tightened 1,
The tightening device can be stored and managed separately from the tightening device 5 without risk of damage, and there is no need to dispose of the tightening object together when it wears out, so there is no waste.
