Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clamp device for securely fixing a midway portion of a rope when the luggage is fixed or pulled by the rope.

[0002]

[Prior art]

 Conventionally, various types of devices for fixing the middle portion of the rope have been devised, and the typical one is, for example, the one described in Japanese Utility Model Publication No. 5-27426. That is, it is a structure in which the rope that passes through the frame is fixed mainly by a cam or a clamp, and at that time, the rope pulling direction and the clamp tightening direction are aligned to prevent the rope from coming off. there were. For this reason, the rope receiving groove and the cam lever are pressed at an acute angle in order to fix them more firmly than in the past, and as a result, the pressing area is reduced. Therefore, when trying to fix the rope firmly, the rope may be worn or deformed, causing damage, which is also a problem from the viewpoint of safety and reliability. In addition, the clearance when passing the rope is also small, so deformed or bent wire rope etc. was difficult to install and the work efficiency was poor. Further, in the conventional clamp device, for example, when tightening a load such as a truck, if the load is not correctly loaded on the loading platform or if a heavy load is fixed, the vehicle vibration will occur due to adverse conditions on the road during traveling. As a result, the rope loosened and came off, causing a load collapse. Since it is difficult to find the cause of such looseness and disconnection of the rope in a stationary state, it is dangerous and requires skill to clamp the load of a load such as a truck. It was reported that it would lead to a major accident.

[0003]

[Problems to be solved by the device]

 For this reason, the clamp device for ropes can be fixed without loosening or coming off even if there is vibration, and it is required that ropes can be easily hooked and workability is good, and the development thereof has been required. Is.

[0004]

[Means for Solving the Problems]

 The present invention has been devised to solve the above-mentioned problems of the related art, and a cam for fixing the problem does not come off due to vibration, etc. A device was provided to solve the problem, and the lock pin could be easily operated.

[0005]

[Action]

 A clamp composed of a frame provided with a receiving groove and a cam lever for fixing the rope inserted through the frame is equipped with a lock pin for fixing the cam lever to the frame, and the receiving groove provided with the lock pin on the frame. The cam lever is fixed by engaging with.

[0006]

【Example】

 Hereinafter, the present invention will be described with reference to an embodiment of the accompanying drawings. This clamp device A is composed of a frame 1, a cam lever 2 and a lock pin 3. The frame and the cam lever are made of SS material (iron), and the lock pin and the cam lever shaft are made of harder 45C material. It is heat treated. The manufacturing method is not limited to this, and it is clear that forging can also be used. Further, the reinforcing portion 12 may be fixed by welding a press material or the like. A receiving groove 11 for the rope B opened to the inside is formed in a curved shape at the upper end of the frame 1, and a hole for fixing the cam lever shaft 21 and a hole for inserting the lock pin 3 are provided in the flat portion. ing. Also, the cam lever stopper 25 is projected at a fixed position. On the other hand, the cam lever 2 has an upper end surface formed in an elliptical shape for pressing the rope B and has a pressing area larger than that of the conventional one, so that the rope B is protected from being damaged, damaged or damaged. ing. Further, a lock pin handle 31 is fixed to the lock pin 3 at a right angle, and a stopper 32 is fixed to the lock pin handle 31 in the direction of the frame 1, which is the same direction as the lock pin 3. . The clamp device A is completed by combining the respective components configured as described above, and the lock pin 3 is inserted into and fixed to the spring case 22 of the cam lever 2 via the spring 23. It can move freely in the direction of the frame 1 and can be inserted into the hole formed in the frame 1. The cam lever 2 is rotatably fixed to the frame 1 by a cam lever shaft 21. By rotating the upper end, the rope B in the portion of the receiving groove 11 of the frame 1 is pressed to be in a positional relationship. That is, when the lock pin 3 is pulled out from the frame 1, the cam lever 2 is rotated to open the rope B, and when the lock pin 3 is fitted into the lock pin receiving groove 13, the cam lever 2 is fixed and the rope B is pulled out. The cam lever 2 is fixed by the elliptical pressing portion at the upper end. Then, the fixed lock pin 3 is fixed in the lock pin receiving groove 13, and the cam lever 2 is fixed by the lock pin receiving portion 24. When removing the rope B fixed in this way, the lock pin 3 is pulled out from the frame 1 and the stopper 32 of the lock pin is moved to the lock pin receiving portion 24, so that the lock pin 3 comes out of the frame 1. The cam lever 2 can be freely rotated, and the work for easily removing the rope B can be performed, which can be easily performed with one hand. Further, the cam lever stopper 25 attached to the frame 1 is attached in order to prevent the cam lever from rotating more than necessary when the cam lever 2 is rotated and the rope is removed, which improves workability. It contributes. During normal use, when the clip with the lock pin mechanism is pulled by using the pulling tool, the lock pin 3 is fitted into the lock receiving groove 13 before the maximum functional state in the pressed state due to the configuration of the clip, so that the lock function reliably operates. After that, press the rope B with the maximum function. Also, during the process of movement, it is automatically in a use start state. By using the lock pin 3 in this way, workability is improved and work safety is ensured, the rope B can be securely fixed, and inadvertent load collapse can be prevented.

[Effect of device]

 As described above in detail, the clamp device according to the present invention is: 1. A rope is hung and fixed by a cam lever, and the cam lever is prevented from loosening. Also, since it is fixed with a lock pin, the rope is extremely unlikely to come off. 2. When the lock pin is inserted into the lock pin receiving groove due to the action of the spring, a clicking sound is generated, which makes it easy to confirm with the ear and eyes when working. 3. The receiving groove of the rope is elliptical and gentle, so the pressing area is large and it can be pressed reliably and reasonably. The rope is less worn and damaged, which is economical and safe, and the rope hanging work is easy. The efficiency of workability is improved. It has various advantages not seen in the past, and its simple structure makes it suitable for mass production and can be supplied inexpensively. Its utility is extremely large.
