Abstract

The utility model discloses a self-locking fixed hinge. The self-locking fixed hinge comprises a shaft as well as a left hinge and a right hinge which are connected by the shaft, wherein a plurality of mounting holes are respectively formed in the left hinge and the right hinge; the left hinge and the right hinge can rotate around the shaft; a plurality of long shaft sleeves are uniformly formed in one side of the left hinge; short shaft sleeves with corresponding quantity are uniformly arranged on one side of the right hinge; the shaft penetrates through and is arranged in the long shaft sleeves and the short shaft sleeves; a deep hole is formed in the lower surface of each long shaft sleeve; a spring is mounted in each deep hole; the lower end of each spring is connected with a steel ball; a circle of concave pits are uniformly distributed in the upper surfaces of the short shaft sleeves; and the steel balls are tightly contacted with the concave pits under the action of the springs. According to the self-locking fixed hinge disclosed by the utility model, the function of fixing the hinges is achieved by adopting a mode of mounting a fixing mechanism among the shaft sleeves; and in addition, the fixing mechanism consist of the springs, the steel balls and the concave pits for fixing the steel balls, so that the fixed hinge is convenient for moving again.

Description

The fixed hinge of self-locking

Technical field

The utility model relates to a kind of hinge, relates in particular to the fixed hinge of a kind of self-locking.

Background technology

Have a lot of objects in the life and have the folding function, as door and window, case lid etc. are on one side by hinge is installed on the folding parts, second half is installed on the fixed part and realizes.But existing hinge has just been realized the function of folding parts around the hinge axis rotation, be not provided with self-locking mechanism, need fix as door, then existing mode is mechanism for installing between door and wall, not only bother, influence attractive in appearance, and need very big strength fixed mechanism could be separated, door is re-moved.

Summary of the invention

The purpose of this utility model is, provides a kind of hinge to fix, and the fixed hinge of being convenient to move again after fixing of self-locking.

For realizing the purpose of this utility model, intend by the following technical solutions:

The fixed hinge of self-locking, comprise axle and the left hinge and the right hinge that connect by axle, described left hinge and right hinge can rotate around axle, it is characterized in that, left side hinge one side evenly is provided with some major axis covers, right hinge one side evenly is provided with the short sleeve of respective numbers, and described axle is arranged in major axis cover and the short sleeve;

Described major axis cover soffit is provided with a deep hole, and a spring is installed in the deep hole, and the lower end of spring connects a steel ball;

The upper surface of described short sleeve is evenly distributed with a circle pit.

Steel ball closely contacts with pit under the effect of spring.

Be equipped with some installing holes on left side hinge and the right hinge.

The utility model is by overlapping the mode that soffit and short sleeve upper surface arrange fixed mechanism at adjacent major axis, realized the function of Fixed hinge, and this fixed mechanism is made up of a circle pit of the spring in the major axis cover soffit deep hole and the steel ball that links to each other with the spring lower end and short sleeve upper surface, when the folding hinge, major axis cover and short sleeve rotate around axle, in the time of in steel ball moves to pit, under the effect of spring, closely contact with pit, play the function of Fixed hinge, when needs rotated hinge again, only need apply bigger slightly power to hinge can shift out steel ball from pit.The utility model not only carries fixed mechanism, and fixed mechanism by spring, steel ball and fixedly the pit of steel ball form, also make the hinge after fixing be convenient to move again.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

In conjunction with Fig. 1, Fig. 4, the fixed hinge of self-locking that present embodiment proposes, comprise left hinge 1, right hinge 2 and axle 3, be equipped with some installing holes 10 on left side hinge 1 and the right hinge 2, hinge be installed on the object that needs folding by installing hole 10, left hinge 1 one sides evenly are provided with five major axis covers 4, right hinge 2 one sides evenly are provided with five short sleeves 5, major axis cover 4 and short sleeve 5 are spaced, and axle 3 is arranged in major axis cover 4 and the short sleeve 5, and left hinge 1 and right hinge 2 can be around axle 3 rotations.

In conjunction with Fig. 2, Fig. 5, Fig. 7, first major axis of left hinge 1 the top overlaps 4 soffits and is provided with a deep hole 6, and a spring 7 is installed in the deep hole 6, and the lower end of spring 7 connects a steel ball 8, and 7 pairs of steel balls of spring 8 produce downward pressure.

In conjunction with Fig. 3, Fig. 6, Fig. 7, the soffit of first short sleeve, 5 upper surfaces of right hinge 2 the tops and left hinge 1 first major axis cover 4 is adjacent, and first short sleeve, 5 upper surfaces are provided with a circle pit 9, the position of this pit 9 is located on the path of steel ball 8 rotations, the size of the size of pit 9 and steel ball 8 is complementary, and the quantity of pit 9 can be determined according to actual user demand.

When hinge installs, be after left hinge 1 is connected by axle 3 with right hinge 2 and spring 7 all is in place with steel ball 8, rotate any a slice hinge, because steel ball 8 is closely contacted with short sleeve 5 upper surfaces of right hinge 2 by spring 7 elastic force effects, steel ball 8 is being fixed within the pit 9 under the effect of spring 7 after changing pit 9 over to, reaches the purpose of locking hinge.When needs rotated hinge again, only need apply bigger slightly power to hinge can shift out steel ball 8 from pit 9.

Claims

1. the fixed hinge of self-locking, comprise axle and the left hinge and the right hinge that connect by axle, described left hinge and right hinge can rotate around axle, it is characterized in that, left side hinge one side evenly is provided with some major axis covers, right hinge one side evenly is provided with the short sleeve of respective numbers, and described axle is arranged in major axis cover and the short sleeve;

2. the fixed hinge of self-locking according to claim 1 is characterized in that, described steel ball closely contacts with pit under the effect of spring.
