A kind of hinge improves structure

Technical field

The utility model relates to the hardware-joint technical field, and particularly a kind of hinge improves structure.

Background technology

Hinge is the connection tumbler that door is connected with doorframe and rotates around doorframe, by people are familiar with.Most of door hinges generally are made up of two braces that are fixed on the core on the existing market, are equipped with fixing hole on two braces, during connection, a common brace by screw on doorframe, another brace then by screw on door.Like this, just can rotate freely between door and the doorframe, realize the switch of door.Existing hinge is unreasonable reason because of structure is provided with, and has deficiency and defective.As in rotary course, the axle core contacts with the adjusting nut face, and big frictional force is arranged, and causes adjusting nut to be deviate from easily, influences the hinge folding; In addition, friction or collision taking place easily also between two leaf of hinge, influences folding.So hinge is carried out technological innovation, necessitates.

The utility model content

For overcoming the deficiencies in the prior art and defective, the utility model provides a kind of hinge to improve structure, have simple in structure, characteristics are set rationally etc.

The purpose of this utility model is achieved in that

A kind of hinge of the utility model improves structure, and it comprises a core, is sheathed on last page body and following page body and upper end cover and bottom end cover on the core; The described page body of going up is made up of with the last brace of fixedlying connected with upper bush upper bush, and described page body down is made up of with the following brace of fixedlying connected with lower sleeve lower sleeve, and described axle core is sheathed on respectively in upper bush and the lower sleeve at two ends up and down; Be provided with adjusting nut between described axle core bottom and the bottom end cover, the upper surface of adjusting nut is provided with recess, is provided with steel ball in the recess, and described concave depth is less than the diameter of steel ball.

Further, described axle core is connected with lower sleeve with upper bush respectively with Lower shaft sleeve by Upper shaft sleeve; Upper shaft sleeve and upper bush clamping, Lower shaft sleeve and lower sleeve clamping.

Enter ground, a ground, described Upper shaft sleeve lower end is provided with first protuberance, and described Lower shaft sleeve upper end is provided with second protuberance.

Further, described upper bush inwall is provided with first groove, and described Upper shaft sleeve outer wall is provided with the first protruding footpath, and the size shape in the size shape of described first groove and the first protruding footpath is complementary; Described lower sleeve inwall is provided with second groove, and described Lower shaft sleeve outer wall is provided with the second protruding footpath, and the size shape in the size shape of described second groove and the second protruding footpath is complementary.

The beneficial effects of the utility model are: be provided with adjusting nut between axle core bottom described in the utility model and the bottom end cover, the upper surface of adjusting nut is provided with recess, be provided with steel ball in the recess, described concave depth is less than the diameter of steel ball, can guarantee effectively that like this spool core bottom and steel ball carry out contacting, the friction of axle core bottom when having reduced rotation, therefore adjusting nut can not come off, and greatly improves overall quality of the present utility model.In addition, the utility model is simple and reasonable, and is easy to use.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

As shown in Figure 1 and Figure 2, a kind of hinge of the utility model improves structure, and it comprises a core 6, is sheathed on last page body 2 and the following page body 3 on the core 6 and is located at the upper end cover 1 and the bottom end cover 10 at two ends up and down; Axle core 6, last page body 2, following page body 3, upper end cover 1 and bottom end cover 10 all adopt the higher metal material of hardness to make.

The described page body 2 of going up is made up of with the last brace 22 of fixedlying connected with upper bush 21 upper bush 21, and described page body 3 down is made up of with the following brace 32 of fixedlying connected with lower sleeve 31 lower sleeve 31.Described axle core is sheathed on respectively in upper bush 21 and the lower sleeve 31 at two ends about in the of 6.

Be provided with adjusting nut 8 between described axle core 6 bottoms and the bottom end cover 10, the upper surface of adjusting nut 8 is provided with recess 81, is provided with steel ball 9 in the recess 81, and the degree of depth of described recess 81 is less than the diameter of steel ball 9.Be provided with like this, when rotated, axle core 6 bottoms form point with steel ball 9 and contact, the bigger frictional force that reduced, adjusting nut 8 can so and not come off, greatly improve the utility model stability, total quality is greatly improved.
