Technical Field

[0001] This utility model relates to the technical field of bushings, specifically to a detachable and combinable compressor bushing. Background Technology

[0002] Composite bushings are high-performance composite bearing assemblies, composed of a metal housing and a polymer liner assembled using precision processes, combining structural strength with self-lubricating properties. Their design typically employs a split or nested structure, facilitating installation and maintenance, and enabling them to withstand radial, axial, and eccentric loads under complex operating conditions.

[0003] According to Chinese Patent No. CN209875742U, a combined bushing includes a first bushing, a second bushing, and a third bushing arranged on the same central axis. The first bushing, the second bushing, and the third bushing are interconnected. The first bushing, the second bushing, and the third bushing are all arc-shaped bodies with equal thickness and arc. A first fixing plate and a second fixing plate are respectively provided at both ends of the first bushing. A third fixing plate and a fourth fixing plate are respectively provided at both ends of the second bushing. A fifth fixing plate and a sixth fixing plate are respectively provided at both ends of the third bushing. A first protrusion and a first threaded hole are provided at the end of the first fixing plate.

[0004] In the above solution, two fixing plates are used to fix multiple bushings together, which still has the following disadvantages: when assembling two bushings together and then assembling the last bushing, the last bushing may fall off during assembly because the first two bushings are not fixed together. Utility Model Content

[0005] The purpose of this invention is to provide a detachable and combinable compressor bushing to solve the problem that the last bushing may fall off during assembly if the first two bushings are not fixed together.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a detachable and combinable compressor bushing, comprising an assembly groove and an assembly plate. The assembly groove is formed on the surface of the main bushing, and the assembly plate is fixed to one end of the secondary bushing. The assembly groove and the assembly plate are slidably engaged. A snap-fit ​​groove is formed on the inner wall of the assembly groove. An installation groove is formed on the top surface of the assembly plate. Two limiting plates are slidably arranged inside the installation groove. Sliding grooves are formed on both sides of the two limiting plates that are close to each other. A sliding rod is slidably arranged between the two limiting plates. A spring is wound on the surface of the sliding rod, and the two ends of the spring are respectively fixed to the two sides of the two limiting plates that are close to each other.

[0007] Preferably, two limiting grooves are respectively opened on both sides of the inner side of the mounting groove, and positioning plates are respectively fixed on both sides of the limiting plate, and the limiting grooves and positioning plates are slidably engaged.

[0008] Preferably, a positioning groove is provided on the inner bottom surface of the assembly slot, and a positioning hemisphere is fixed on the bottom surface of the assembly plate, with the positioning groove and the positioning hemisphere slidingly engaged.

[0009] Preferably, two mounting plates are fixed to the surfaces of both the main bushing and the secondary bushing, and mounting holes are provided on the top surface of the mounting plates.

[0010] Preferably, the inner wall surfaces of the main bushing and the secondary bushing are fixed with a heat-resistant layer.

[0011] Preferably, the main bushing has two oil injection holes at one end.

[0012] Preferably, storage slots are provided on the two sides of the two limiting plates that are close to each other, and a protective arc plate is slidably arranged between the two limiting plates. The storage slots are slidably engaged with the protective arc plate. Two fixing holes are provided on the top surface of the limiting plates. Several threaded grooves are provided on the bottom surface of the mounting slot. Fixing bolts are inserted into the fixing holes. The bottom end of the fixing bolts passes through the fixing holes and is threadedly connected to the threaded grooves.

[0013] Compared with existing technologies, a detachable and combinable compressor bushing using the above-mentioned technical solution has the following advantages:

[0014] 1. When the assembly plate is fully slid into the assembly slot, the two limiting plates will slide in opposite directions under the action of the spring return force, and can be locked into the inside of the locking slot to complete the locking between the main bushing and the secondary bushing. The fiberboard is then locked into the inside of the locking slot using fixing bolts, which increases the firmness of the installation between the main bushing and the secondary bushing.

[0015] 2. Workers can add lubricating oil to the inside of the main bushing and the secondary bushing through the L-shaped oil injection hole. When the assembly plate is inserted into the inside of the assembly slot, the positioning hemisphere will be inserted into the inside of the positioning slot, which can initially fix the position between the main bushing and the secondary bushing. During the use of the bushing, the heat-resistant layer on the inner wall of the main bushing and the secondary bushing will rub against the moving parts to reduce wear. The heat-resistant layer can be used to increase the high temperature resistance of the main bushing and the secondary bushing. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a detachable and combinable compressor bushing includes an assembly groove 3 and an assembly plate 4. The assembly groove 3 is formed on the surface of the main bushing 1, and the assembly plate 4 is fixed to one end of the secondary bushing 2. The assembly groove 3 and the assembly plate 4 are slidably engaged. The assembly groove 3 has a snap-fit ​​groove 5 on its inner wall, and the assembly plate 4 has an installation groove 6 on its top surface. Two limiting plates 7 are slidably disposed inside the installation groove 6. Sliding grooves 8 are formed on both sides of the two limiting plates 7 that are close to each other. A sliding rod 9 is slidably disposed between the two limiting plates 7. A spring 10 is wound around the surface of the sliding rod 9, and the two ends of the spring 10 are respectively engaged with the two sides of the two limiting plates 7 that are close to each other. The two limiting plates 7 are fixed separately, and storage slots 19 are respectively opened on both sides of the two limiting plates 7. A protective arc plate 20 is slidably arranged between the two limiting plates 7. The storage slots 19 and the protective arc plate 20 are slidably engaged. Two fixing holes 21 are opened on the top surface of the limiting plate 7. Several threaded slots 22 are opened on the bottom surface of the inner side of the mounting slot 6. Fixing bolts 23 are inserted into the fixing holes 21. The bottom end of the fixing bolts 23 passes through the fixing holes 21 and is threadedly connected to the threaded slots 22. Two limiting slots 11 are respectively opened on both sides of the inner side of the mounting slot 6. Positioning plates 12 are fixed on both sides of the limiting plate 7. The limiting slots 11 and the positioning plates 12 are slidably engaged.

[0023] During use, when the main bushing 1 and the secondary bushing 2 are assembled together, the assembly plate 4 will be installed inside the assembly groove 3. When the assembly plate 4 enters the assembly groove 3, the two limiting plates 7 will be squeezed into the installation groove 6 by the inner wall of the assembly groove 3 and come closer to each other, and the spring 10 will be compressed. When the limiting plate 7 passes through the assembly groove 3 and enters the snap-fit ​​groove 5, the compressed spring 10 will return and push the two limiting plates 7 away from each other, so that they can enter the interior of the snap-fit ​​groove 5. Finally, the worker will pass the fixing bolt 23 through the fixing hole 21 and thread it into the threaded groove 22 to fix the limiting plate 7 inside the snap-fit ​​groove 5. During the sliding process of the limiting plate 7, the protective arc plate 20 will protect the sliding rod 9 and the spring 10 above, preventing the spring 10 from being directly protected by the external environment. When the limiting plate 7 slides inside the installation groove 6, the positioning plate 12 will slide synchronously inside the limiting groove 11. The sliding cooperation between the positioning plate 12 and the limiting groove 11 can be used to prevent the limiting plate 7 from falling out of the installation groove 6.

[0024] Subsequently, the fixing bolt 23 is inserted through the fixing hole 21 of the limiting plate 7 and connects with the threaded groove 22 at the bottom of the mounting groove 6, further reinforcing the position of the limiting plate 7 in the snap-fit ​​groove 5. During the sliding process, the protective arc plate 20 is located above the sliding rod 9 and the spring 10, providing shielding and protection to prevent the spring 10 from being directly exposed to the external environment. The sliding fit between the positioning hemisphere 14 and the positioning groove 13 further precisely corrects the assembly position of the main bushing 1 and the secondary bushing 2, avoiding assembly misalignment.

[0025] like Figure 2 and Figure 4 As shown, a positioning groove 13 is provided on the bottom surface of the assembly groove 3, and a positioning hemisphere 14 is fixed on the bottom surface of the assembly plate 4. The positioning groove 13 and the positioning hemisphere 14 are slidably engaged. Two mounting plates 15 are fixed on the surfaces of the main bushing 1 and the secondary bushing 2. Mounting holes 16 are provided on the top surface of the mounting plates 15. A heat-resistant layer 17 is fixed on the inner wall surface of the main bushing 1 and the secondary bushing 2. Two oil injection holes 18 are provided at one end of the main bushing 1.

[0026] During use, workers can add lubricating oil to the inside of the main bushing 1 and the secondary bushing 2 through the L-shaped oil injection hole 18. When the assembly plate 4 is inserted into the inside of the assembly groove 3, the positioning hemisphere 14 will be inserted into the inside of the positioning groove 13, which can initially fix the position between the main bushing 1 and the secondary bushing 2. During the use of the bushings, the heat-resistant layer 17 on the inner wall of the main bushing 1 and the secondary bushing 2 will rub against the moving parts to reduce wear. The heat-resistant layer 17 can be used to increase the high temperature resistance of the main bushing 1 and the secondary bushing 2.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
