Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Embodiment one

Please refer to Figure 1-5, a plug with its own clamping function line, including the plug body 1 and the wire 2, the plug body 1 and the wire 2 are fixedly connected, and the power can be conducted through the wire 2 by plugging the plug body 1 into the socket.

The tail of the plug body 1 is fixedly connected with a fixing block 3 , there are two fixing blocks 3 , and the two fixing blocks 3 are symmetrically arranged on both sides of the plug body 1 .

One end of the fixed block 3 is fixedly connected with a fixed column 4, and the fixed block 3 is arranged at an end away from the plug body 1. The inner wall of the fixed column 4 is slidably connected with an extension rod 8, and the extension rod 8 can slide along the inner wall of the fixed column 4 under force.

The outer wall of the extension rod 8 is rotatably connected with the sleeve 5 for fixing the electric wire 2. The extension rod 8 can be rotated along the inner wall of the sleeve 5 under force. The inner wall of the sleeve 5 is provided with three through holes, and the two extension rods 8 extend to the inner wall of the sleeve 5 respectively. 5, the stress point of the wire 2 can be extended downwards, which can effectively protect the contact part between the plug body 1 and the wire 2 from being pulled, and improve the service life of the plug body 1.

The outer wall of the extension rod 8 is slidably connected with a clamping block 6. When the clamping block 6 is squeezed, it will slide along the inner wall of the extension rod 8. The inner wall of the fixed column 4 is provided with a plurality of clamping grooves 9 for engaging with the clamping blocks 6. When the clamping blocks 6 engage with the clamping grooves 9, the extension rod 8 will fix the current position. At this time, the contact position between the sleeve 5 and the electric wire 2 will change with the sliding of the extension rod 8, thereby changing the stress point of the electric wire 2, so as to protect the plug body 1 and the electric wire 2. The effect of the connection site.

The inner wall of the extension rod 8 is provided with an accommodating groove for the clamping block 6. When the clamping block 6 is blocked, it will slide to the inner cavity of the accommodating groove. The return spring 7 releases the elastic potential energy and pushes the clamping block 6 into the inner cavity of the clamping groove 9 to complete the fixing of the extension rod 8 to the current position.

The outer wall of the extension rod 8 is fixedly connected with a positioning block 10. The positioning block 10 and the clamping block 6 are located on the same horizontal plane.

One end of the clamping block 6 close to the positioning block 10 is set as an inclined surface. When the extension rod 8 is pulled, the inclined surface provided by the clamping block 6 can contact the inner wall of the engaging groove 9. With the sliding of the extending rod 8, the inner wall of the engaging groove 9 will push the engaging block 6 into the inner cavity of the accommodating groove again. At this time, the extending rod 8 can slide along the inner wall of the fixed column 4, which is convenient for adjusting the position of the force point of the electric wire 2.

The top surface of the clamping block 6 is set as an inclined plane, and the two inclined planes provided on the outer wall of the clamping block 6 are in an adjacent relationship. The inclined plane provided on the top surface of the clamping block 6 can be contacted with the inner wall of the top of the clamping groove 9 by rotating the extension rod 8, and the clamping block 6 can be pushed back into the inner cavity of the accommodation groove. The block 10 is rotated to the horizontal position of the engaging groove 9 to engage the engaging block 6 with the engaging groove 9 again.

Embodiment two

Referring to Figure 1-5, Comparative Example 1, as another embodiment of the present invention, the outer wall of the extension rod 8 is fixedly connected with a fixed ring 11, and the inner wall of the sleeve 5 is provided with a rotation groove for the rotation of the fixed ring 11, so that the rotation of the extension rod 8 will not be affected, and at the same time, the sleeve 5 can be connected with the outer wall of the extension rod 8 through the cooperation of the fixed ring 11 and the rotation groove.

The two symmetrically arranged extension rods 8 are both connected to the inner wall of the sleeve 5, which can effectively prevent the sleeve 5 from rotating along the outer wall of the electric wire 2 and reduce the protection effect.

The inner wall of the sleeve 5 is fixedly connected with a rubber pad, and the rubber pad can protect the outer wall of the electric wire 2 .

The working principle is that by pulling the extension rod 8 from the inner wall of the fixing column 4, the outer wall of the sleeve wire 2 slides. When sliding for a certain distance, the extension rod 8 drives the clamping block 6 to engage with the clamping groove 9, and the current position of the sleeve 5 can be fixed. When the wire 2 is pulled, the force point of the wire 2 can be changed, which effectively solves the problem that when the wire 2 is pulled, the wire 2 and the plug are in a bent state, which is very easy to cause damage to the connecting part.
