Description

[0001] The utility model relates to the technical field of copper sleeves, in particular to a self-lubricating copper sleeve for installation joints. Background Technique

[0002] In cases where it is necessary to protect pipe joints, reduce friction and wear, and improve sealing performance, the copper sleeve can be used as a bushing or casing for pipe joints. Installing the copper sleeve inside or outside the pipe joint can effectively reduce friction and wear during metal contact, which is particularly important for pipe systems that often need to be disassembled and installed, and can extend the service life of the joints and pipes.

[0003] After retrieval, Chinese Patent Publication No.: CN217421880U discloses a self-lubricating copper sleeve. By embedding reinforcing ribs in the copper sleeve body, the strength and hardness of the copper sleeve body itself can be greatly enhanced, preventing deformation during operation.

[0004] Considering that when the existing copper sleeve is in use, lubricating materials such as graphite are usually installed on the copper sleeve. When the copper sleeve rubs, a self-lubricating effect will be generated. Considering lubrication only through graphite materials, in high-temperature or extreme chemical environments, graphite will fail due to chemical reactions or oxidation, resulting in a decrease in lubrication performance and a weakening of the lubrication effect, leading to a reduction in the lubrication effect and service effect of the self-lubricating copper sleeve. Therefore, a self-lubricating copper sleeve for installation joints is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a self-lubricating copper bushing for an installation joint, including a copper bushing body 1. A groove 6 is provided on the outer wall of the copper bushing body 1 to limit the rotation ring 2, so that the rotation ring 2 can only slide along the inner wall of the groove 6. A feed port 3 is provided on the inner wall of the groove 6, and multiple groups of feed ports 3 are distributed. By adding graphite material into the feed port 3, the graphite can produce a self-lubricating effect on the copper bushing body 1. A rotation ring 2 is rotatably connected to the inner wall of the groove 6, and a lubrication component 4 is provided on the rotation ring 2. Through the lubrication component 4, the copper bushing body 1 can be self-lubricated by lubricating oil. Thus, through the self-lubricating effect of the copper bushing body 1, at the left end of the top of the rotation ring 2, a fueling component 5 is provided. Through the fueling component 5, it is convenient to add lubricating oil into the cavity 42, and at the same time, it can seal the fueling pipe 51.

[0034] Refer to Figure 2 - Figure 4 , the lubrication component 4 includes ball bearings 41, and multiple groups of ball bearings 41 are symmetrically distributed in an annular array. A cavity 42 is provided on the inner wall of the rotation ring 2. The cavity 42 is formed by connecting two annular grooves through four through grooves, so that lubricating oil can be released on both the left and right sides of the rotation ring 2 to produce a lubricating effect. Oil injection holes 47 are provided on the inner wall of the cavity 42, and multiple groups of oil injection holes 47 are symmetrically distributed in an annular array. Through the oil injection holes 47, the lubricating oil in the cavity 42 can be injected into the cylindrical groove 48. A cylindrical groove 48 is provided on the right side of the rotation ring 2, and multiple groups of cylindrical grooves 48 are symmetrically distributed in an annular array. By opening the cylindrical groove 48, the lubricating oil in the cylindrical groove 48 can be released to lubricate the copper bushing body 1. A circular plate 45 is elastically connected to the inner wall of the cylindrical groove 48 through a spring 46. Under the elastic force of the spring 46, the circular plate 45 always slides in a direction away from the rotation ring 2 when not affected by external forces. A cylindrical rod 44 is fixedly connected to the right side of the circular plate 45, and a spherical head 43 is fixedly connected to the right end of the cylindrical rod 44. Through the movement effect of the cylindrical rod 44, the spherical head 43 is driven to move.

[0035] Refer to Figure 1 and Figure 5, the fueling assembly 5 includes a fueling pipe 51. By opening the top opening of the fueling pipe 51, it is convenient for the staff to add lubricating oil into the cavity 42. The top end of the fueling pipe 51 is plugged with a cover plate 52. By plugging the cover plate 52 with the fueling pipe 51, the cover plate 52 can close the top opening of the fueling pipe 51. Both the left and right sides of the fueling pipe 51 are fixedly connected with buckles 54. Through the fixing effect of the buckles 54, the buckles 54 are prevented from falling off. Both the left and right ends of the bottom of the cover plate 52 are fixedly connected with fixing blocks 55. Through the fixing effect of the fixing blocks 55, the fixing blocks 55 are prevented from falling off. The inner wall of the fixing block 55 is elastically connected with a wedge block 57 through a limiting spring 56. Through the elastic force of the limiting spring 56, the wedge block 57 always maintains the clamping effect with the buckle 54 without external force, thereby limiting the fixing block 55 and keeping the cover plate 52 fixed. The inner wall of the cover plate 52 is fixedly connected with a sealing gasket 53. By squeezing the sealing gasket 53 between the cover plate 52 and the fueling pipe 51, the sealing gasket 53 is expanded and deformed, achieving a sealing effect between the cover plate 52 and the fueling pipe 51.

[0036] Refer to Figure 2 - Figure 4 , the outer circumference of the ball 41 is rotationally connected with the right inner wall of the groove 6. Through the rotation effect of the ball 41, the friction between the ball 41 and the rotating ring 2 is reduced. The outer circumference of the spherical head 43 is slidably connected with the inner wall of the cylindrical groove 48. Through the sliding effect of the spherical head 43, the spherical head 43 can close or open the opening of the cylindrical groove 48. One end of the spring 46 is fixedly connected with the inner wall of the cylindrical groove 48, and the other end of the spring 46 is fixedly connected to the left side of the circular plate 45. Through the fixing effect of the spring 46, the circular plate 45 is kept fixed and prevented from falling off.

[0037] Refer to Figure 5 , the bottom of the fueling pipe 51 is fixedly connected with the top left end of the rotating ring 2. Through the fixing effect of the fueling pipe 51, the fueling pipe 51 is prevented from falling off. The outer wall of the fixing block 55 is plugged into the inner wall of the buckle 54. Through the plugging effect of the fixing block 55 and the buckle 54, the cover plate 52 can be installed on the fueling pipe 51. One end of the limiting spring 56 is fixedly connected with the inner wall of the fixing block 55, and the other end of the limiting spring 56 is fixedly connected to the outer wall of the wedge block 57. Through the fixing effect of the limiting spring 56, the wedge block 57 is kept fixed and prevented from falling off. The outer wall of the wedge block 57 is slidably connected with the inner wall of the fixing block 55. Through the sliding effect of the wedge block 57, the wedge block 57 is clamped or unclamped with the buckle 54. The outer wall of the wedge block 57 is clamped with the bottom of the buckle 54. Through the clamping effect of the wedge block 57 and the buckle 54, the buckle 54 limits the fixing block 55.

[0038] Refer to Figure 4, a chute is provided on the inner wall of the cylindrical groove 48, which limits the circular plate 45 through the chute, improves the stability of the spherical head 43 during movement, the circular plate 45 is slidably connected to the inner wall of the chute, and drives the cylindrical rod 44 to move through the sliding effect of the circular plate 45.

[0039] Working principle: When it is necessary to install the adapter, the staff installs the copper sleeve body 1 on the adapter for use. Subsequently, the staff adds lubricating oil into the cavity 42 through the oil filling pipe 51, closes the cover plate 52, so that the fixing block 55 is inserted into the buckle 54. At the same time, the cover plate 52 and the oil filling pipe 51 squeeze the sealing gasket 53, causing the sealing gasket 53 to expand and deform, achieving a sealing effect on the oil filling pipe 51 and the cover plate 52. At the same time, the wedge block 57 is clamped with the buckle 54 under the elastic force of the limiting spring 56, limiting the fixing block 55, so that the cover plate 52 remains fixedly closed.

[0040] After the lubricating oil is added into the cavity 42, the lubricating oil in the cavity 42 will be injected into the cylindrical groove 48 through the oil injection hole 47. When the copper sleeve body 1 works and generates rotational friction, the graphite material installed in the feed port 3 on the copper sleeve body 1 lubricates the copper sleeve body 1. At the same time, when the copper sleeve body 1 rotates, it will drive multiple groups of balls 41 to rotate around the copper sleeve body 1. When the balls 41 contact the spherical head 43, they will squeeze the spherical head 43, causing the spherical head 43 to open the cylindrical groove 48, so that the lubricating oil in the cylindrical groove 48 flows into the friction surface of the copper sleeve body 1, thereby achieving the self-lubricating effect of the copper sleeve body 1.

[0041] When the balls 41 pass over the spherical head 43 and relieve the extrusion effect on the spherical head 43, the circular plate 45 slides along the inner wall of the chute in the direction away from the rotating ring 2 under the elastic force of the spring 46, causing the cylindrical rod 44 to drive the spherical head 43 to move back to its original position, and closing the oil outlet of the cylindrical groove 48 through the spherical head 43. When the lubricating oil in the cavity 42 is consumed, the staff presses the wedge block 57, causing the wedge block 57 to release the clamping effect with the buckle 54, and at the same time releasing the limiting effect on the fixing block 55, and releasing the insertion effect of the fixing block 55 with the buckle 54, so as to facilitate the staff to remove the cover plate 52 and add oil to the oil filling pipe 51.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
