Quick connector device

Abstract

The invention relates to a quick clamping and releasing device and a quick connector device with the quick clamping and releasing device. The quick clamping and releasing device comprises a clamping device body, and the body comprises an outer clamping sleeve and more than one clamping rod. The outer clamping sleeve comprises a side wall, and the inner surface of the side wall is a work surface. The clamping rods are evenly and symmetrically distributed along the side wall of the outer clamping sleeve, and the clamping ends of the clamping rods penetrate through the side wall of the outer clamping sleeve and are hinged to the outer clamping sleeve on the side wall of the outer clamping sleeve. Connecting holes are formed in the force application ends of the clamping rods. The rotating track of the contact position of the clamping ends of the clamping rods and a piece to be clamped along a hinge shaft is an involute or an Archimedes helix. Objects of different shapes and sizes can be clamped fast, and the problem that a hoisted piece is hard to hoist due to the fact that a steel wire rope cannot penetrate through the hoisted piece is solved. The quick clamping and releasing device can be used as a light pipe quick connector device and a tool for pipeline pressure testing and climbing, the operation is convenient, the structure is simple, cost is low, the application range is wide, and the application condition is wide.

Description

technical field [0001] The invention relates to a clamping device and a quick joint device. Background technique [0002] Existing clamping devices are varied and of great variety, each having its own advantages and disadvantages. Such as: [0003] A quick clamping device disclosed in ZL201220481905.1 is suitable for a wide range of diameters, but it is only suitable for clamping round objects. It is difficult to manufacture the inner rack on it. If the tooth pitch is small, the strength will be low. When the clamped part is large and hard, it is likely to be difficult to clamp; at the same time, there is a problem that it is not easy to disassemble. [0004] Chinese invention patent application 201110376678.6 discloses a quick clamping Hafu block, ZL200520070064.4 discloses a quick clamping mechanism, ZL00232625.6 discloses a quick pipe clamp, etc.; all can achieve the purpose of quick clamping, but they are also It is only suitable for the clamping of round objects and ...

Problems solved by technology

[0003] A quick clamping device disclosed in ZL201220481905.1 is suitable for a wide range of diameters, but it is only suitable for clamping round objects. It is difficult to manufacture the inner rack on it. If the tooth pitch is small, the strength will be low. When the clamped part is large and hard, it is likely to be difficult to clamp; at the same time, there is a problem that it is not easy to disassemble

[0004] Chinese invention patent application 201110376678.6 discloses a quick clamping Hafu block, ZL200520070064.4 discloses a quick clamping mechanism, ZL00232625.6 discloses a quick pipe clamp, etc.; all can achieve the purpose of quick clamping, but they are also It is only suitable for the clamping of round objects and has strict requirements on the outer diameter of the clamped parts; otherwise, there will be problems that are not easy to clamp

In addition, the aforementioned clamping devices all require long linkages or wrenches, making them often inoperable when used in tight spaces

[0005] In addition to the above-mentioned problems, the quick clamping device disclosed in ZL201320056193.3 and ZL201220050081.2 and the clamp for connecting soft and hard pipes disclosed in Chinese invention patent application 201210548479.3 are complicated in structure

[0006] It can be seen that there is a common problem in the prior art, that is, most of the existing clamping devices are only suitable for cylindrical objects to be clamped, and have strict requirements on the diameter of the clamped
