Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pneumatic winch connecting components, and specifically relates to a connecting component for a pneumatic winch. Background Technique
[0002] A pneumatic winch uses a vane-type pneumatic motor as the power source, and transmits the power to the drum through a planetary gear reducer to lift heavy objects. The pneumatic winch motor and the reducer are respectively connected to both sides of the drum, making the winch small in size, light in weight, compact in structure, simple to operate, convenient to maintain, and capable of achieving stepless speed regulation within a certain range. The braking of the winch is achieved through motor braking, and the braking is reliable.
[0003] When connecting the cable of a pneumatic winch, it is usually directly knotted manually. This connection method is inconvenient when dealing with cables with slightly harder materials, and it is easy for the knot to come loose due to the elasticity of the cable itself, resulting in the failure of the cable connection, which is very dangerous. Therefore, a connecting component for a pneumatic winch is proposed to solve the above-mentioned problems. Content of the Utility Model

This connection method is inconvenient when dealing with cables with slightly harder materials, and it is easy for the knot to come loose due to the elasticity of the cable itself, resulting in the failure of the cable connection, which is very dangerous.
[0006] (2) Technical Solution
[0007] The technical solution for the utility model to solve the above technical problems is as follows: A connecting component for a pneumatic winch includes a sliding sleeve, and a cable connecting sleeve extending above it is slidably connected inside the sliding sleeve. An L-shaped cable hole is opened inside the cable connecting sleeve. A sliding locking block extending into the L-shaped cable hole is slidably connected to the outside of the cable connecting sleeve.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0025] In the embodiment, it is given by Figures 1-3 A connecting member for a pneumatic winch. The present invention includes a sliding sleeve 1. A cable connecting sleeve 2 extending above it is slidably connected to the inner side of the sliding sleeve 1. An L-shaped cable hole 3 is formed inside the cable connecting sleeve 2. A sliding locking block 4 extending into the L-shaped cable hole 3 is slidably connected to the outside of the cable connecting sleeve 2. A cable groove 5 is formed on the outside of the sliding locking block 4. An inclined surface pressing block 6 in contact with the sliding locking block 4 is fixedly installed between the front and rear inner walls of the sliding sleeve 1. A connecting block 7 is rotatably connected to the bottom of the sliding sleeve 1. A clamping pin 8 is connected to the outside of the connecting block 7. The connecting block 7 is connected to a cargo hook 9 through the clamping pin 8.
[0026] Furthermore, a fillet is provided at the bending part of the L-shaped cable hole 3, and the inner diameter of the L-shaped cable hole 3 is adapted to the arc radius of the cable groove 5.
[0027] Particularly, the sizes of the L-shaped cable hole and the cable groove should be adaptively adjusted according to the state of the pneumatic winch cable and should be adapted to it.
[0028] Furthermore, both the end of the sliding locking block 4 located inside the cable connecting sleeve 2 and the inner side of the cable groove 5 are provided with knurling.
[0029] Furthermore, the cross-section of the sliding sleeve 1 is C-shaped and its inner left wall is in contact with the cable connecting sleeve 2. The gap between the right side of the sliding locking block 4 and the inclined surface pressing block 6 is adapted to the inner diameter of the L-shaped cable hole 3.
[0030] Particularly, a turning groove corresponding to the position of the sliding locking block 4 should be provided inside the cable connecting sleeve 2. The cable is bent through the sliding locking 4 through the turning groove to obtain greater friction.
[0031] Furthermore, a sliding groove is formed inside the cable connecting sleeve 2, and a limiting sliding block extending into the sliding groove is fixedly installed on the outside of the sliding locking block 4.
[0032] Furthermore, the connecting block 7 is C-shaped, and the outer end of the clamping pin 8 is provided with a thread and connected with a locking nut.
[0033] Working principle:
[0034] When the device is connected, the cable connecting sleeve 2 is slid downward and removed, and then the cable is passed through the L-shaped cable hole 3 and the end of the cable is passed through the cable groove 5 and wrapped around the sliding locking block 4. At this time, the cable connecting sleeve 2 can be placed again inside the sliding sleeve 1. At this time, the cable connecting sleeve 2 is slid upward along the sliding sleeve 1 and the end of the cable is passed through the gap between the cable connecting sleeve 2 and the inclined extrusion block 6. When the cable connecting sleeve 2 continues to slide, the inclined extrusion block 6 and the cable located inside the cable groove 5 begin to be squeezed, and at the same time, pressure is applied to the sliding locking block 4 toward the inside of the cable connecting sleeve 2. At this time, friction can be applied to the cable in the L-shaped cable hole 4 and the cable in the cable groove 5 at the same time through the sliding locking block 4, thereby completing the connection between the cable and the device. The connection process does not require tying a knot, and only the cable position needs to be guided, which is extremely convenient.
