Abstract

The utility model discloses a smoothly rotating door hinge which comprises a bracket, an upper shaft sleeve, an upper rotating shaft, a lower shaft sleeve, a lower rotating shaft and a hinge, wherein the upper shaft sleeve and the lower shaft sleeve are vertically and fixedly distributed on the bracket, the upper rotating shaft is inserted in the upper shaft sleeve, the lower rotating shaft is inserted in the lower shaft sleeve, plane bearings are respectively sheathed on the upper rotating shaft and the lower rotating shaft and are in compression joint between the end surface of the upper shaft sleeve and the end surface of the hinge as well as between the end surface of the lower shaft sleeve and the end surface of the hinge. After the improvement of the structure, as a door leaf is arranged on the hinge, the weight born by the hinge is entirely transferred to the plane bearings, so that the door leaf can rotate more smoothly and quietly.

Description

Rotate door hinge smoothly

Technical field:

The utility model relates to a kind of rotation door hinge smoothly.

Background technology:

The door hinge of prior art mainly contains support, loose-leaf, axle sleeve and turning cylinder and constitutes, axle sleeve is rack-mount, and turning cylinder and door leaf all are installed on the loose-leaf, turning cylinder injects axle sleeve, during rotation,, add the weight of door leaf because axle sleeve end face and loose-leaf end face produce friction, make the friction of axle sleeve end face and loose-leaf end face even more serious, influence is rotated and is also sent ear-piercing grating simultaneously.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, to provide a kind of rotation smooth and easy, quiet door hinge.

For achieving the above object, the technical scheme that the utility model provides is: rotate door hinge smoothly, include support, Upper shaft sleeve, go up rotating shaft, Lower shaft sleeve, lower rotary shaft and loose-leaf, Upper shaft sleeve and Lower shaft sleeve are fixed on the support with distribution one on the other, Upper shaft sleeve is injected in last rotating shaft, lower rotary shaft injects Lower shaft sleeve, all is set with plane bearing on last rotating shaft and lower rotary shaft, and plane bearing is crimped between axle sleeve end face and the loose-leaf end face.

After architecture advances, because door leaf is mounted on the loose-leaf, the whole referrals of the weight that loose-leaf bears are to plane bearing, thereby make the rotation of door leaf more smooth and easy, peace and quiet.

Description of drawings:

Fig. 1 is the three-dimensional exploded view of the utility model door hinge;

Fig. 2 is the sectional structure chart of the utility model door hinge.

The specific embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

Present embodiment rotates smoothly, and door hinge includes support 1, Upper shaft sleeve 2, go up rotating shaft 3, Lower shaft sleeve 4, lower rotary shaft 5 and loose-leaf 6, Upper shaft sleeve 2 and Lower shaft sleeve 4 are fixed on the support 1 with distribution one on the other, Upper shaft sleeve is injected in last rotating shaft 3, lower rotary shaft 5 injects Lower shaft sleeve 4, all be set with plane bearing 7 on last rotating shaft 3 and lower rotary shaft 5, plane bearing 7 is crimped between axle sleeve end face and the loose-leaf end face.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.

Claims

1. rotate door hinge smoothly, include support, Upper shaft sleeve, go up rotating shaft, Lower shaft sleeve, lower rotary shaft and loose-leaf, Upper shaft sleeve and Lower shaft sleeve are fixed on the support with distribution one on the other, Upper shaft sleeve is injected in last rotating shaft, lower rotary shaft injects Lower shaft sleeve, it is characterized in that: all be set with plane bearing on last rotating shaft and lower rotary shaft, plane bearing is crimped between axle sleeve end face and the loose-leaf end face.
