[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] Embodiment 1: Reference Figure 2 and Figure 3 The embodiment of the present application discloses a container door hinge bearing gasket structure, which includes: A base 1, which is in the shape of a hollow cylinder; The annular groove 11 is formed on the end surface of the base 1 and extends along the axial direction of the base 1, and the annular groove 11 does not penetrate the axial direction of the base 1; The tapered rollers 2 are provided in plurality and are distributed on the bottom wall of the annular groove 11 at equal intervals in the annular direction. Specifically, the tapered rollers 2 are distributed in a circular array at equal intervals in the axial direction of the base 1. The unit rotor 3 is annular and slidably disposed in the annular groove 11, and the tapered roller 2 is located between the unit rotor 3 and the bottom wall of the annular groove 11; An upper cover plate 4, the center of which has a through hole and is snap-fitted with the base 1; The positioning ring 41 is fixedly connected to a side of the upper cover plate 4 close to the unit rotor 3 and is used to press the unit rotor 3 onto the tapered roller 2, wherein the positioning ring 41 is coaxial with the upper cover plate 4 and is integrally formed.
[0021] In addition, the above-mentioned components can be made of stainless steel or other hard materials, and the upper cover plate 4 and the outer wall of the base 1 can also be provided with a spray paint layer to integrate with the color of the container fixtures.
[0022] In this way, when the hinge bearing gasket of the present application is used, by arranging a plurality of tapered rollers 2 in the annular groove 11, the rotation bearing effect of the hinge bearing gasket is mainly achieved by the rolling of the unit rotor 3 on the plurality of tapered rollers 2 when the container door is opened and closed, and the sliding friction of the bearing gasket as a whole can be changed into rolling friction, which can greatly reduce the difficulty of opening and closing the container door; and it can also reduce the wear between the door panel hinge, the gasket and the folding seat, and improve the service life; in addition, the unit rotor 3, the base 1 and the upper cover plate 4 are all arranged as a detachable structure, which is convenient for replacing the unit rotor 3 of suitable thickness under different assembly requirements to meet the stable rotation requirements of the chain bearing gasket, so that the processing accuracy requirements for the original structure of the container door can be greatly reduced, the fault tolerance rate is higher, and the economic effect is extremely significant.
[0023] Specifically, the base 1 is provided with a plurality of tapered grooves 12 adapted to the plurality of tapered rollers 2 on the bottom wall of the annular groove 11, the tapered rollers 2 are arranged in the tapered grooves 12, and the cone tops of the tapered rollers 2 are arranged near the hollow part of the base 1, and the taper of the tapered rollers 2 can be specifically 5°; correspondingly, the two axial end faces of the unit rotor 3 are arranged in parallel and the axial end faces thereof are arranged in an inclined manner, and the end of the axial end face of the unit rotor 3 close to the inner arc side thereof is lower than the end of the outer arc side thereof. Moreover, after the tapered roller 2 is completely embedded in the tapered groove 12, the tapered roller 2 partially protrudes from the bottom wall of the tapered groove 12, and the end of the protruding part close to the hollow part of the base 1 is lower than the end close to the outer arc side of the base 1.
[0024] In this way, by setting the tapered groove 12, the tapered roller 2 can be effectively prevented from detaching during rotation, so as to ensure the stability of the unit rotor 3 during rotation; and the lower side inclined surface of the unit rotor 3 is designed to fit the angle of the tapered roller 2, so that the unit rotor 3 has a centripetal effect when rotating, ensuring that all components are in coaxial rotation, preventing falling off, and reducing maintenance costs; and the tapered roller 2 has a taper of 5°, which is suitable for scenarios with lower rotation speeds. This taper is easy to process and reduce costs, and has a certain centripetal effect, which can further ensure the stability of the unit rotor 3 during rotation.
[0025] In addition, the outer arc side of the positioning ring 41 is fixedly connected with an outer edge guard 411 that fits the outer arc side of the unit rotor 3, and the outer edge guard 411 is integrally formed with the positioning ring 41. Moreover, the upper cover plate 4 is fixedly connected with a sleeve 42 that is sleeved on the outer periphery of the base 1, and the inner arc side of the sleeve 42 is fixedly connected with a first clamping edge 421, and the first clamping edge 421, the sleeve 42 and the upper cover plate 4 are integrally formed, and the first clamping edge 421 is arranged on the inner arc side of the end of the sleeve 42 away from the upper cover plate 4; the outer arc side of the base 1 is fixedly connected with a second clamping edge 13, and the outer diameter of the second clamping edge 13 is adapted to the inner diameter of the sleeve 42, and the first clamping edge 421 and the second clamping edge 13 are both provided with transition surfaces 5, and when the upper cover plate 4 and the base 1 are buckled and connected, the transition surfaces 5 at the two locations are arranged in a back-to-back manner, and the transition surface 5 can be an inclined surface or an arc surface.
[0026] In this way, by setting the outer guard 411, the unit rotor 3 can be rotationally limited to prevent the unit rotor 3 from shaking in the annular groove 11 when rotating; and the setting of the first clamping edge 421 on the sleeve 42 and the setting of the second clamping edge 13 on the base 1 can prevent the upper cover plate 4 and the base 1 from falling off when the unit rotor 3 rotates, avoid structural failure, and ensure safe operation. At the same time, the cooperation between the first clamping edge 421 and the second clamping edge 13 can not only realize the convenient assembly of the upper cover plate 4 and the base 1, but also prevent rainwater from intruding, thereby effectively achieving waterproofing.
[0027] In addition, a lubricating layer is provided in the annular groove 11, and the lubricating layer at least covers the portion where the tapered roller 2 protrudes from the bottom wall of the annular groove 11. The lubricating layer can be a grease lubricant, which can not only improve the rotation, but also prevent rust from both the material and protection aspects, thereby extending the service life; and an anti-slip structure 6 is provided at one end of the upper cover plate 4 where the positioning ring 41 is not provided and at one end of the base 1 where the annular groove 11 is not provided, which can increase the roughness of the two end surfaces of the hinge bearing gasket of the present application to ensure that the external rotation can be effectively transferred to between the unit rotor 3 and the multiple tapered rollers 2 to prevent failure of the rotation structure.
[0028] The implementation principle of a container door hinge bearing gasket structure in the embodiment of the present application is: When the hinge bearing gasket of the present application is used, by arranging a plurality of tapered rollers 2 in the annular groove 11, the rotation bearing effect of the hinge bearing gasket is mainly achieved by the rolling of the unit rotor 3 on the plurality of tapered rollers 2 when the container door is opened and closed, and the sliding friction of the bearing gasket as a whole can be changed into rolling friction, which can greatly reduce the difficulty of opening and closing the container door; and can also reduce the wear between the door panel hinge, the gasket and the folding seat, and improve the service life; in addition, the unit rotor 3, the base 1 and the upper cover plate 4 are all arranged as a detachable structure, which is convenient for replacing the unit rotor 3 of suitable thickness under different assembly requirements to meet the stable rotation requirements of the chain bearing gasket, thereby greatly reducing the processing accuracy requirements for the original structure of the container door, with a higher fault tolerance rate and extremely significant economic effects.
[0029] Embodiment 2: Reference Figure 4 and Figure 5 The difference between the embodiment of the present application and the embodiment 1 is that: The two axial end faces of the unit rotor 3 are respectively provided with an annular anti-skid protrusion 31 and an anti-skid groove 32, the anti-skid protrusion 31 and the anti-skid groove 32 are plugged and adapted, at least one unit rotor 3 is arranged in the annular groove 11, if multiple unit rotors 3 are arranged, multiple unit rotors 3 are arranged in a superimposed manner; the side of the positioning ring 41 close to the unit rotor 3 is provided with an anti-skid groove 32. In the specific setting, the thickness of the unit rotor 3 can be 2mm-6mm, for example, 5mm, when the thickness of the unit rotor 3 is small, the anti-skid protrusion 31 and the anti-skid groove 32 can be stamped and formed in one piece; when the thickness of the unit rotor 3 is large, the anti-skid protrusion 31 and the anti-skid groove 32 can be machined.
[0030] In this way, by respectively arranging matching anti-slip protrusions 31 and anti-slip grooves 32 on the two end surfaces of the unit rotor 3, it is possible to prevent the unit rotor 3 from falling off when sliding, effectively enhancing the safety of use, and multiple unit rotors 3 can be overlapped to increase the overall thickness of the hinge bearing gasket to adapt to the distances between different door panel hinges and folding seats; and the unit rotors 3 can be mass-produced according to standard parts and flexibly assembled at the site of use, further reducing the use cost of the hinge bearing gasket of the present application.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
