Description

[Detailed description of the invention] This invention relates to a temporary lock in which a hook plate is slid back and forth to engage or disengage from a receiver etc. by rotating the operating shaft in the forward and reverse directions.The purpose of this invention is to have a simple structure. To provide a temporary tightening lock that allows an operator to quickly sense the necessity of continuing operation of a hook plate at its most retracted position, and prevents the operating shaft from rotating in the opposite direction when the hook plate is at its most retracted position. It's about doing.

The gist of this invention is to provide a mounting plate, a guide plate whose one end is pivotally connected to a pin fixed to the side wall of the mounting plate, and a guide plate that engages with a guide groove of the guide plate. a hook plate that slides forward and backward; an operating shaft that is rotatably attached to the guide plate and has a cam on its tip engaged with a long hole formed in the hook plate; and a handle that rotates the operating shaft in forward and reverse directions. In the temporary lock, a recess is formed in the distal end surface of the operating shaft, and the hook plate is provided with a tongue piece that comes into sliding contact with the distal end surface of the operating shaft, and the hook plate slides to the most retracted position. Then, when the cam comes into contact with the end of the elongated hole, the tongue piece engages with the recess of the operating shaft.

FIGS. 1 to 10 show a temporary lock according to an embodiment of this invention. This temporary lock is mainly used on the mounting plate 1.
and a guide plate 3 whose one end side 3a is wound around a pin 2 fixed to the side walls 1a and 1b of the mounting plate 1 so as to be rotatably connected (see FIG. 6); and the guide plate 3.
a hook plate 4 that engages with a guide groove 3b (see FIG. 9) and slides up and down in FIG.
an operating shaft 5 which is rotatably mounted on the hook plate 4 and has a cam 6 on the tip end surface 5a engaged with a long hole 4a (see FIG. 8) formed in the hook plate 4, and a handle for rotating the operating shaft 5 in forward and reverse directions. As shown in FIG. 6, a concave portion 5b is formed in the distal end surface 5a of the operating shaft 5, and the hook plate 4 is provided with a tongue piece 4b that comes into sliding contact with the distal end surface 5a of the operating shaft 5. A small hole 1c is formed in the back surface 1b of the mounting plate 1, and the temporary lock is inserted into this small hole 1c.
It is attached to a door etc. with bolts and nuts etc. at c. In this case, both sides of the guide groove 3b of the guide plate 3 are bent inward. Further, a mounting hole 3c is formed in the guide plate 3 so that the operating shaft 5 can be rotatably mounted therein. In the figure, numeral 8 is a side protection plate of the operating shaft 5, and 9 is a top protection plate. As shown in FIG. 7, the handle portion 7 is formed with hook portions 7a, 7a.
a is hung on the upper surface protection plate 9, thereby allowing the operation shaft 5 to be rotated in forward and reverse directions.

In this way, the tip hook portion 4c of the hook plate 4 is hooked onto the receiver, etc., and the handle portion 7 is moved from the most extended position as shown in FIG.
When rotated around arrow A, the operating shaft 5 also rotates,
While the cam 6 moves to the left end of the elongated hole 4a and returns to the right end, the hook plate 4 slides while being guided by the guide grooves 3b to the most retracted position shown in FIG. At the most retracted position of this hook plate 4, the tongue piece 4
b engages with the concave portion 5b of the operating shaft 5 (see Fig. 6), but since the engagement sound and the feel of the engagement are immediately transmitted to the operator, the operator can avoid any further trouble. Necessary rotational operation can be stopped. Therefore, the hook part 7a of the handle part 7 or the side protection plate 8 or top protection plate 9 of the operating shaft 5 is
This avoids damage caused by continued unnecessary rotational operation. Moreover, this engagement prevents the operating shaft 5 from rotating in the opposite direction due to vibration or some kind of impact.

In the above-mentioned embodiment, the hook plate 4 is formed with a letter-shaped groove 4d, and the protruding piece 4e of the letter-shaped groove 4d is provided with the tongue piece 4b, so that the tip end surface 5a of the operating shaft 5 Even when the protrusion 4e slides into contact with the tongue 4b, the elasticity of the protruding piece 4e is effective, and the occurrence of friction noise or wear is appropriately prevented, and furthermore, a suitable engagement sound is generated when engaged.
