Detailed Description

The following detailed description of the present invention is provided for illustration in conjunction with the accompanying drawings and examples, which should be understood by those skilled in the art to be non-limiting in the scope of the present invention.

The protection device of this embodiment adopts metal material, through the motion mode of screw thread transmission moment, realizes locking and the loosening of protection device. The device mainly comprises a base 1, a locking clamping hook 2, a release screw 3, a sealing ring 4, a cover plate 5, a screw 6 and the like.

As shown in fig. 1 and 2, the base 1 has a cavity for accommodating the locking hook 2, and the front end of the base 1 is open and serves as a passage port for the locking hook 2 to move back and forth; the locking clamping hook 2 is of a symmetrical structure and comprises a clamping hook base body and a pair of clamping hook arms which respectively extend forwards at the left end and the right end of the clamping hook base body, hook parts at the front ends of the pair of clamping hook arms are arranged oppositely, and a connector mounting surface is fixedly arranged at the front part of the cavity of the base 1 and behind the hook parts corresponding to the clamping hook arms; the outer side walls of the pair of hook arms and the corresponding left and right inner side walls of the base 1 are guiding matching structures, and specifically, the guiding matching structures can be strip-shaped concave-convex matching structures (not obviously shown in the figure). The release screw 3 penetrates through the middle position of the rear portion of the base 1, the clamping hook base body is provided with a threaded hole in the corresponding position, the clamping hook base body and the release screw 3 are in threaded fit, the locking clamping hook 2 drives the clamping hook base body to move back and forth under the action of the release screw 3, and accordingly forward release/backward locking of the connector with the barb is achieved.

In order to ensure that the locking hook 2 still cannot fall off from the base 1 when being separated from the loose screw 3, the front end and the rear end of the guide matching structure can be respectively provided with a limiting structure. For example, the outer side wall of the clamping hook arm is provided with a convex block, the left and right inner side walls corresponding to the base are strip-shaped grooves, and plugs are formed at the front end and the rear end of each strip-shaped groove, so that the moving stroke of the convex block is limited.

To facilitate the assembly of the protective device, the top of the base 1 may be empty and covered by a cover plate 5, and the cover plate 5 is fixedly connected to the top of the two sides of the base 1 by two screws 6.

The locking hook 2 is preferably an integrated piece made of metal materials, so that different use scenes can be met, and different environment reliability requirements can be easily met; moreover, various surface treatments can be carried out, the appearance requirements of different industries and different occasions are met, and the texture and the aesthetic feeling of the product are improved.

The edge of the connector mounting surface is provided with a sealing ring in a circle, and the sealing ring is connected with the barbed connector in a mounting mode in a usual mode.

As shown in fig. 3 and 4, the trip base can be driven forward/backward by manually rotating the release screw 3. The connector with the barb is moved forwards, namely the distance between the hook part of the locking clamping hook 2 and the connector mounting surface of the base 1 is pulled open, so that the connector with the barb can be conveniently arranged in the locking clamping hook 2; the rearward movement, i.e., the distance of the hook portion of the locking hook 2 from the connector mounting surface is contracted, locks the barbed connector on the connector mounting surface of the base 1. In the same way, the barbed connector can be loosened and taken down by reverse operation.
