Necklace anti-pull structure

Abstract

The invention relates to a necklace anti-pull structure, comprising a necklace, wherein a first connector and a second connector are fixed at both ends of the necklace respectively; a socket for inserting the second connector is arranged at the end of the first connector, and a damping rubber sleeve matched with the second connector is fixedly arranged in the socket; the inner hole of the damping rubber sleeve is in the shape of an elliptical cylinder; the second connector is in the shape of a cylinder, and a plurality of groups of arc-shaped protrusions are symmetrically arranged on the side surface; during assembly, the second connector is inserted into the damping rubber sleeve in the socket, at which time the arc-shaped protrusions are aligned with the two elliptical ends of the inner hole of the damping rubber sleeve, and the second connector is rotated after being inserted into place, so that the arc-shaped protrusions squeeze the damping rubber sleeve to deform it, and a positioning effect is achieved by relying on the squeezing force. When encountering external pulling force, when the arc-shaped protrusion is pulled out of the socket, the damping rubber sleeve and the arc-shaped protrusion interact with each other to form a damping buffer, thereby achieving the effect of preventing the necklace itself from being torn off.

[0007] The necklace anti-pull structure described in the present invention is characterized in that a second metal spring sheet cooperating with the protrusion is provided on the inner wall of the insertion hole; the second metal spring sheet includes a ring-shaped mounting plate, and an elastic metal contact sheet is provided on the inner wall of the mounting plate.

[0008] The necklace anti-pull structure described in the present invention is characterized in that a plurality of metal contact pieces are arranged on the inner wall of the mounting piece.

[0009] The beneficial effects of the present invention are as follows: during assembly, the second connector is inserted into the damping rubber sleeve in the socket, at which time the arc-shaped protrusion is aligned with the two elliptical ends of the inner hole of the damping rubber sleeve, and the second connector is rotated after being inserted into place, so that the arc-shaped protrusion squeezes the damping rubber sleeve to deform it, and the positioning effect is achieved by relying on the squeezing force. When encountering external pulling force, the arc-shaped protrusion moves out of the socket under the pulling force, and the damping rubber sleeve interacts with the arc-shaped protrusion to form a damping buffer, thereby achieving the effect of preventing the necklace itself from being torn off.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0016] The necklace anti-pull structure of the preferred embodiment of the present invention is as follows Figure 1 See also Figure 2 , Figure 3 and Figure 4 , including a necklace 1, with a first connector 2 and a second connector 3 fixed at both ends of the necklace respectively; a socket 20 for inserting the second connector 3 is provided at the end of the first connector 2, and a damping rubber sleeve 200 cooperating with the second connector 3 is fixedly provided in the socket 20; the inner hole of the damping rubber 200 is an elliptical cylinder; the second connector 3 is cylindrical, and a plurality of groups of arc-shaped protrusions 30 are symmetrically provided on the side surface; during assembly, the second connector is inserted into the damping rubber sleeve in the socket, at this time, the arc-shaped protrusions are aligned with the two elliptical ends of the inner hole of the damping rubber sleeve, and the second connector is rotated after being inserted into place, so that the arc-shaped protrusions squeeze the damping rubber sleeve to deform it, and the positioning effect is achieved by relying on the squeezing force. When encountering external pulling force, when the arc-shaped protrusion moves out of the socket under the pulling force, the damping rubber sleeve and the arc-shaped protrusion interact with each other to form a damping buffer, thereby achieving the effect of preventing the necklace itself from being torn off.
