Description

Line pressing structure

Technical Field

The utility model relates to a line ball technical field especially relates to a line ball structure.

Background

All be provided with the wire in switch or the socket, must need a line ball structure like this to fix the wire, general line ball structure includes line ball screw and gasket, compresses tightly the wire with the gasket through screwing the line ball screw, realizes the line ball purpose, but prior art's line ball screw and gasket are all more ordinary, when adorning the gasket to the line ball screw in, the gasket drops very easily, and is not very convenient when installing like this.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: the wire pressing structure is convenient to install and use.

The utility model adopts the technical proposal that: the wire pressing structure comprises a wire pressing screw and a gasket, wherein a through hole for the wire pressing screw to pass through is formed in the gasket, a clamping pin is arranged on the circumference of the through hole, and a convex block for the clamping pin to clamp a main body is arranged at the bottom of the wire pressing screw.

Compared with the prior art in the structure more than adopting, the utility model has the advantages of it is following: the clamp pins are arranged on the circumference of the through hole, the convex blocks are arranged at the bottom of the line pressing screw, and therefore when the gasket is installed in the line pressing screw, the gasket can be limited on the convex blocks at the bottom of the line pressing screw through the clamp pins, the gasket can be well prevented from falling off from the line pressing screw, and the installation and the use are more convenient.

Preferably, the number of the clamping pins is four, and the four clamping pins are uniformly arranged on the circumference of the through hole. Four clamping feet are symmetrically arranged, so that the stress is more uniform, and the limiting effect is better.

Preferably, the convex block is a convex ring arranged on the circumference of the bottom of the line pressing screw, and the diameter of the lower end face of the convex ring is larger than that of the upper end face. By the arrangement, the clamping pins on the gasket can be clamped on the convex blocks of the line pressing screws well no matter the gasket rotates to any angle.

Preferably, the distance between the two opposite clamping feet is larger than the diameter of the upper end surface of the convex ring and smaller than the diameter of the lower end surface of the convex ring. Thus, the clamping pin can better clamp the main bump.

Preferably, a groove is further arranged between the thread part of the line pressing screw and the bump, and the thickness of the groove is matched with that of the gasket. Because the part of the screw does not need to be used, the groove can be made to save a part of cost, and the lug processing is also convenient.

Detailed Description

The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the following specific embodiments.

The utility model provides a line ball structure, includes line ball screw 1 and gasket 2, wherein:

the line pressing screw 1 comprises a screw head and a screw rod, wherein an annular bump 5 is arranged at the bottom of the screw rod, the diameter of the lower end face of the annular bump 5 is A, the diameter of the upper end face of the annular boss is B, and A is larger than B; the lower part of the annular boss is provided with a groove 6, and the width of the groove 6 is matched with the thickness of the gasket 2; the lower part of the groove 6 is a threaded part, and the maximum diameter part in the threaded part is C, and A is more than C and more than B;

a through hole 3 for a screw rod to pass through is formed in the middle of the gasket 2, four clamping pins 4 are uniformly arranged on the periphery of the through hole 3 on the upper end surface of the gasket 2, the area of the upper end surface of each clamping pin 4 is smaller than that of the lower end surface of the corresponding clamping pin, namely the area of the clamping pins 4 fixedly connected with the upper end surface of the gasket 2 is larger, and further the strength of the clamping pins 4 is higher; a circle is formed among the four clamping pins 4, the diameter of the circle is D, and A is more than D and more than B is satisfied; and the up end of the four sides of gasket 2 all sets up slottedly, and the lower extreme is equipped with the arch corresponding to the trench position to four angles downward sloping settings of gasket 2, these structures all can be so that the whole line ball effect of line ball structure is better.

When this application line ball structure used, pass through the through-hole 3 of gasket 2 with the lead screw of line ball screw 1 earlier, make gasket 2 stretch into the screw bottom, when card foot 4 and lug 5 contact, can be slightly inclined down gasket 2, make 2 whole can up-move of gasket, even make card foot 4 pass through the lower terminal surface of lug 5, then put flat gasket 2 again, card foot 4 on the gasket 2 this moment just can block lug 5 on the main line ball screw 1, when the installation like this, gasket 2 can not break away from line ball screw 1.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
