Technical Field

The technical scheme relates to the technical field of hinges, in particular to an oilless hinge.

Background

The hinge is also called hinge, and is a two-fold part which is a part for connecting two parts of an object and enabling the two parts to move, and the hinge is a device for connecting or rotating and generally comprises a first hinge and a second hinge, and the first hinge and the second hinge are hinged, so that a door, a cover or other swinging parts can rotate.

Chinese patent CN113153040a discloses a hinge, which has the following drawbacks:

1. the first hinge and the second hinge are in direct contact, when the hinge rotates, the abrasion condition is serious, and noise can be generated.

2. After long-time use, first hinge and second hinge junction are because the friction can produce the iron fillings, and the iron fillings can be attached to on the hinge, if meet the rainy day, rainwater doping iron fillings extremely easily makes the hinge rust, influences the hinge use.

Disclosure of Invention

The technical scheme aims at providing an oilless hinge, which solves the problems of short service life and noise of an ordinary hinge by arranging a plane bearing and a bearing sleeve between the hinge and a connecting shaft.

The technical scheme aims at realizing the following steps:

an oilless hinge comprising:

a first blade on which a first hinge is provided;

a second blade provided with a second hinge portion thereon;

the connecting shafts are arranged in the first hinging part and the second hinging part through a plurality of plastic shaft sleeves, so that the first blades and the second blades are rotationally connected;

the plane bearing is sleeved outside the connecting shaft, and the end faces of the plane bearing are respectively abutted against the first hinge part and the second hinge part.

Preferably, the planar bearing is sleeved with a bearing sleeve.

Preferably, a cap is provided on the first hinge part, and the cap is in threaded connection with the first hinge part.

Preferably, the first blade and the second blade are provided with mounting holes.

Preferably, the mounting hole is provided as a counter bore.

Preferably, the plastic sleeve is configured as a POM sleeve.

Compared with the prior art, the technical scheme has the advantages that:

1. according to the utility model, the first blade and the second blade are hinged on the connecting shaft, and the planar bearing sleeved on the connecting shaft can avoid direct surface-to-surface contact rotation of the first blade and the second blade when the hinge rotates, so that friction force between the first blade and the second blade is reduced when the hinge rotates, abrasion between the first blade and the second blade is further reduced, noise is avoided, the plastic shaft sleeve has good abrasion resistance and self-lubricating property, friction force between the hinge and the plastic shaft sleeve and between the plastic shaft sleeve and the connecting shaft is small when the hinge rotates, abrasion loss is small, sound is not easy to make, and meanwhile, the service life of a product can be prolonged.

2. After the cap is connected with the first hinge part, the enclosed space is used for limiting the connecting shaft, so that the connecting shaft can be ensured to be always connected with the first blade and the second blade and cannot slip.

Detailed Description

The following describes the specific embodiments of the present technical solution in further detail with reference to the accompanying drawings.

An oilless hinge comprising:

a first blade 1 on which a first hinge 11 is provided;

a second blade 2 on which a second hinge 21 is provided;

the connecting shaft 3 is arranged in the first hinging part 11 and the second hinging part 21 through a plurality of plastic shaft sleeves 6, so as to realize the rotary connection between the first blade 1 and the second blade 2, and the plastic shaft sleeves 6 are arranged as POM (point of sale) sleeves;

the planar bearing 4 is sleeved outside the connecting shaft 3, and the end surfaces of the planar bearing are respectively abutted against the first hinge part 11 and the second hinge part 21. The connecting shaft 3 is a cylindrical long rod, two first hinging parts 11 are arranged on the first blade 1, the first hinging parts 11 and the second hinging parts 21 are all arranged as splicing pipelines with annular cross sections, the first blade 1 and the second blade 2 are sleeved outside the connecting shaft 3 through the splicing pipelines, four plastic shaft sleeves 6 are also arranged between the splicing pipelines and the connecting shaft 3, the number of the plane bearings 4 is two and are respectively arranged at two ends of the second hinging parts 21, the end surfaces of the plane bearings 4 respectively collide with the first hinging parts 11 and the second hinging parts 21, the plane bearings 4 reduce the rotating friction force between the first blade 1 and the second blade 2, thereby effectively preventing the generation of noise and the abrasion of the hinging parts, the POM sleeve comprises a first POM sleeve, a second POM sleeve, a third POM sleeve and a fourth POM sleeve, wherein the first POM sleeve and the fourth POM sleeve are used for connecting the first hinging part 11 and the connecting shaft 3, the second POM sleeve and the third POM sleeve are used for connecting the second hinging part 21 and the connecting shaft 3, the second POM sleeve and the third POM sleeve are arranged in the second hinging part 21, as shown in fig. 3, the inner diameters of the four POM sleeves are the same, the outer diameter of the position a is larger than the outer diameter of the position B, the arrangement directions of the other three POM sleeves are all that the end sides with larger outer diameters are close to the plane bearing 4, the end sides with smaller outer diameters are far away from the plane bearing 4, and the arrangement mode can enable the first blade 1 and the second blade 2 to be smoother in rotation without blocking.

Preferably, the bearing sleeve 5 is sleeved outside the plane bearing 4. The bearing sleeves 5 are sleeved outside the two plane bearings 4, the width of each bearing sleeve 5 is slightly smaller than that of each plane bearing 4, each bearing sleeve 5 is used for sealing the corresponding plane bearing 4, the plane bearing 4 is prevented from being polluted by outside dust and water vapor, meanwhile, each bearing sleeve 5 is further used for supporting the corresponding first hinge part 11 and the corresponding second hinge part 21, and the plane bearing 4 is prevented from being damaged due to overlarge pressure at the upper end and the lower end.

Preferably, be provided with the block 7 on the first articulated portion 11, block 7 and first articulated portion 11 threaded connection, all be provided with mounting hole 8 on first blade 1 and the second blade 2, mounting hole 8 sets up to the counter bore, and the quantity of block 7 sets up to two, installs respectively on corresponding first articulated portion 11, and after the block 7 is installed, seals connecting axle 3, prevents that external steam dust from getting into its inside influence connecting axle 3 use, and the hinge passes through the screw fixation on the carrier, and the counter bore is used for providing the mounted position for the screw thread head, can guarantee after the installation is accomplished, first blade 1 and second blade 2 surfacing, pleasing to the eye just can not the hand.
