Technical proposal

The utility model provides a difficult not hard up composite contact, includes the mounting panel, be provided with extrusion space in the lower surface of mounting panel, run through on the roof in extrusion space has the mounting hole, the inside matrix that has inserted of mounting hole, the upper end of matrix is fixedly provided with the contact layer, the lower extreme fixedly connected with sliding connection of matrix in extrusion plate in extrusion space, the downside fixedly connected with spring of extrusion plate, still be provided with control space in the lateral wall in extrusion space, control space with sliding connection has the push pedal subassembly of purpose-made shape in the extrusion space, still be provided with in the control space and be used for the push pedal subassembly provides the screw subassembly of being convenient for of the dismantlement of extrusion force.

Further, the push plate assembly comprises a flat plate abutted with the spring, and an arc-shaped plate for improving bending strength is fixedly connected to the lower side of the flat plate.

Further, the screw assembly includes a threaded bore extending through a top wall of the control space.

Further, a through hole penetrating through the push plate assembly is formed in the right lower side of the threaded hole.

Further, a screw which is in threaded connection with the threaded hole is arranged in the through hole in a penetrating mode.

Further, the extrusion space is tightly attached to the extrusion plate and can limit the extrusion plate to rotate.

Further, the push plate assembly can only slide up and down in the control space and the extrusion space.

Advantageous effects

Compared with the prior art, the utility model has the following beneficial effects: through the integrated configuration that sets up arc and dull and stereotyped for adopt less thinner material just can obtain sufficient bending strength in order to supply normal use, can not produce too big bending deformation because of the extrusion of spring, also alleviateed material quantity and whole weight simultaneously, through the setting of screw and screw hole moreover, make the dismantlement of overall structure change more convenient.

Detailed Description

For a better illustration of the present utility model, the following description is made with reference to the accompanying drawings and examples:

the utility model discloses a composite contact which is difficult to loosen, and the composite contact comprises a mounting plate 1, wherein an extrusion space 3 is arranged in the lower surface of the mounting plate 1, a mounting hole 9 is penetrated through the top wall of the extrusion space 3, a base body 11 is inserted into the mounting hole 9, the upper end of the base body 11 is fixedly provided with a contact layer 10, the lower end of the base body 11 is fixedly connected with an extrusion plate 12 which is fixedly connected with the extrusion space 3, the lower side of the extrusion plate 12 is fixedly connected with a spring 8, a control space 5 is further arranged in one side wall of the extrusion space 3, a specially-shaped push plate assembly 2 is slidably connected between the control space 5 and the extrusion space 3, and a screw assembly 900 which is used for providing extrusion force for the push plate assembly 2 and is convenient to detach is further arranged in the control space 5.

Further, the push plate assembly 2 includes a flat plate 21 abutting against the spring 8, and an arc plate 22 for improving bending strength is fixedly connected to the lower side of the flat plate 21.

Further, the screw assembly 900 comprises a threaded hole 7 extending through the top wall of the control space 5.
