Description

Separate cross wrench with adjustable torque

technical field

The utility model relates to a separate cross wrench structure capable of setting the torque value, in particular to a kind of multiplier that can obtain fast rotation and torque setting only by means of simple knot insertion positioning and adjustment setting. effect, and a more convenient and practical cross wrench structure.

Background technique

Taking the inventor's previous patent No. 200820150528.7 as an example, the so-called "separate cross wrench" refers to a specific wrench structure that can be used for detachable storage and quick assembly, which is very beneficial to packaging, storage and quick assembly. It can be used directly, and at the same time, it has various positive effects such as easy application of force and acceleration of spin, so it is very popular among users. However, the inventor found out later that if a professional user needs to set the torque, in order to avoid possible damage to the screw workpiece caused by excessive force, he must use a so-called screw before tightening the screw workpiece. Only the "torque setting wrench" can complete the final urgent work, which also highlights the small shortcomings of the original design in terms of performance.

Furthermore, as we all know, the so-called "torque setting wrench" (not shown in the figure) refers specifically to a butt design that utilizes the working end and the force application end, and cooperates with the high-strength friction force between the relevant components caused by the strong elastic parts, so that When the applied force of the wrench reaches the set value, there will be obvious setbacks at the butt joint between the working end and the applied end. At this time, the user will immediately know and stop applying force, thereby avoiding the damage caused by excessive force. May hurt.

But so far, in many relevant product literatures, we can easily find that all torque setting wrenches today are mainly designed with F handle type. In short, there is no design similar to cross wrench, so it does not have The performance of easy and fast rotation can not effectively shorten the working hours to enhance work efficiency, unless the user can prepare a cross wrench and a torque setting wrench for alternate use at any time, and this alternate use process is unavoidably cumbersome. Extremely inconvenient feeling, so it really needs to be improved.

Torque value, so as to achieve the expected torque setting purpose.

The utility model mainly takes the separate cross wrench as the design prototype, and changes the side effect lever into a special exclusive structure for setting the torque, so that the separate cross wrench and the torque setting wrench are combined into one, and the two are combined in one fell swoop. Combined display of exclusive functions.

detailed description

In order to make a further understanding of technical means and features of the present utility model, now cooperate with some sketches to describe in detail in the back:

First, as shown in Figures 1, 2, 3, and 4, it includes:

A main action rod 10, one end is a sleeve insertion end 11, for the insertion of the corresponding sleeve 50 to be able to rotate the screw workpiece (not shown in the figure), and the other end is provided with a pivot Rotation-assisted handle 12, moreover, its central part is a thickened middle section 14 with a through hole 13, and a locking button assembly 15 is provided on the side of the through hole 13, so as to cooperate with the torque to set the side effect rod 20 Inserting the inner rod 21 into the ring slot 211 can form the effect of locking or releasing. In addition, an internal thread hole 16 is provided on the bottom side of the thickened middle section 14, so as to lock a positioning bolt 17 and make the positioning bolt The front edge 171 of 17 slightly extends into the through hole 13, and can form a positioning effect with the positioning slot 214 of the corresponding part of the inserted inner rod 21 (see Figure 3);

A torque setting side effect rod 20, including a plug-in inner rod 21 with a spacer ring slot 211, a force applying outer rod 22 with a torque setting component 40 inside, a grip handle 23, and a pushing elastic member 24. A torque adjusting screw cap 25 and a buckle ring 26, wherein the pivoting end 212 of the plug-in inner rod 21 has a pin hole 213, which is used to cooperate with a latch 27 and the corresponding pin hole 221 of the force-applying outer rod 22. The two are plugged and hinged, so as to use the function of the torque adjustment screw cap 25 to rotate and adjust the predetermined torque value of the torque setting assembly 40 , thereby achieving the desired torque setting purpose.

Afterwards, please refer to FIG. 5 again, the torque setting assembly 40 is concealed in the axial inner hole 222 of the force applying outer rod 22, which sequentially includes a pivoting end 212 of the plugged inner rod 21. Top block 41, a strong holding member 42, a sliding block 44 with scale 43, and a group of windows 45 located on the outer periphery of the force-applying rod 22, so that the scale of scale 43 can be observed, wherein the slide The block 44 is intersected and screwed with the corresponding internal thread portion 223 of the outer rod 22 by means of the external thread portion 441, and then a torque adjustment post 443 with a ratchet 442 for driving is established at its open end. Therefore, when the sliding block 44 is pressed The stronger the torsion value will be if the force is pressed more toward the strong holding member 42 (that is, the frictional force between the top block 41 and the pivotal end 212 of the inserted inner rod 21 will be greater), and vice versa.

As for the mode of adjusting and setting the torsion value, as shown in Figures 6 and 7, since the handle 23 is provided with an inner ratchet ring 231 relative to the inner edge of the torque adjustment screw cap 25, the torque adjustment screw cap 25 The corresponding part is provided with an external ratchet ring 251, and a ratchet inner hole 252 for driving and rotating is provided inside. Under normal conditions, the push elastic member 24 will constantly push the torque adjustment screw cap 25 outward, so that the grip screw The inner and outer ratchet rings 231, 251 of the handle 23 and the torque adjustment screw cap 25 are engaged. At this moment, the torque adjustment screw cap 25 will not be able to be rotated (see Figure 6), and then the torque adjustment screw cap 25 will be pushed toward Hold the rotary handle 23 to make it disengage from the inner and outer ratchet rings 231, 251. At this time, the ratchet inner hole 252 of the torque adjustment screw cap 25 will be engaged with the drive ratchet 442 of the torque adjustment column 443 and can be used according to By adjusting the position of the sliding block 44 (see FIG. 7 ), the desired torque value setting purpose can be achieved.

In view of the above, this utility model has not been seen in similar articles on the market and related publications before the application, and has met the application requirements for utility models, and should be protected by the patent law, so the application is filed according to law.
