Description

Technical Field

[0001] This utility model relates to the field of chain track technology, specifically a chain track that facilitates chain disassembly. Background Technology

[0002] Chain tracks, also known as chain guides or chain guides, are a type of hydrostatic guide primarily used to support and guide chains, reducing chain friction, lowering noise, and extending chain lifespan. Chains used for extended periods will require maintenance or replacement due to wear. During chain disassembly, the chain is removed from the chain track. However, current disassembly procedures lack a dedicated positioning structure for the chain, often resulting in the chain floating up and down or swaying left and right. This floating and swaying not only increases the difficulty of disassembly but may also cause unnecessary damage to the chain and track, even affecting subsequent installation and use. Utility Model Content

This floating and swaying not only increases the difficulty of disassembly, but may also cause unnecessary damage to the chain and track, and even affect subsequent installation and use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chain track for easy disassembly of the chain, comprising:

[0005] External support shell;

[0006] The sprocket is symmetrically arranged inside the outer support housing.

[0007] The chain is mounted on the outside of the sprocket;

[0008] A clamping and positioning plate is symmetrically and slidably mounted on the top of the outer support housing.

[0009] Connecting support box, which is located on the outside of the clamping and positioning plate;

[0010] An inner fixing box is set inside the outer support shell. A movable base is symmetrically slidably arranged on the top of the inner fixing box, and the top of the movable base is fixedly connected to the connecting support box.

[0011] The opening is located inside the clamping and positioning plate;

[0012] A support box is slidably mounted on top of one of the connecting support boxes. The support box is slidably connected to the clamping and positioning plate. A push rod is slidably mounted inside the support box for pushing out the pin of the chain.

[0013] Limiting plates are symmetrically arranged inside the clamping and positioning plates to limit the top and bottom of the chain.

[0014] As a preferred embodiment of this utility model: a bidirectional lead screw is rotatably provided inside the inner fixed box, and a movable slide plate is symmetrically threaded to the outer side of the bidirectional lead screw. The movable slide plate is slidably connected to the inner fixed box. A first limiting slide rod is symmetrically slidably provided inside the movable slide plate. The first limiting slide rod is fixedly connected to the inner fixed box. A first rotating handwheel is rotatably provided on one side of the inner fixed box, and one end of the bidirectional lead screw is fixedly connected to the first rotating handwheel.

[0015] As a preferred embodiment of this utility model: a first adjusting screw is rotatably arranged inside the support box, and a top plate is threadedly connected to the outer side of the first adjusting screw. The top plate is slidably connected to the support box, and one end of the top rod is fixedly connected to the top plate. A second limiting slide rod is symmetrically slidably arranged inside the top plate, and the second limiting slide rod is fixedly connected to the support box. A second rotating handwheel is rotatably arranged on one side of the support box, and one end of the first adjusting screw is fixedly connected to the second rotating handwheel.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: a chain track for easy chain disassembly, comprising: an outer support housing 1; a sprocket 2 symmetrically rotated and disposed inside the outer support housing 1; a chain 3 mounted on the outside of the sprocket 2; a clamping positioning plate 20 symmetrically slidably disposed on the top of the outer support housing 1; a connecting support box 10 fixedly connected to the outside of the clamping positioning plate 20; an inner fixing box 4 fixedly connected to the inside of the outer support housing 1, the top of the inner fixing box 4 symmetrically slidably disposed with a movable base 9, the top of the movable base 9 being fixedly connected to the connecting support box 10; a through opening 17 opened inside the clamping positioning plate 20; a support box 11 slidably disposed on the top of one of the connecting support boxes 10, the support box 11 being slidably connected to the clamping positioning plate 20, the inside of the support box 11 being slidably disposed with a push rod 16 for pushing out the pin of the chain 3; and a limiting plate 21 symmetrically fixedly disposed inside the clamping positioning plate 20 for limiting the top and bottom of the chain 3.

[0027] Understandably, when the chain 3 needs to be disassembled, the first rotating handwheel 8 is manually turned. The first rotating handwheel 8 drives the double-acting screw 5 to rotate. When the double-acting screw 5 rotates, it drives the outer movable slide plate 6 to slide within the inner fixed box 4. The movable slide plate 6 drives the movable base 9 to move. The movable base 9 drives the connecting support box 10 and the clamping positioning plate 20 to move. The clamping positioning plate 20 drives the limiting rod 18 to slide against the fixed support plate 19, thus limiting and supporting the movement of the clamping positioning plate 20. The clamping positioning plate 20 clamps and positions the outer side of the chain 3. The limiting plates 21 symmetrically arranged on the inner side of the clamping positioning plate 20 limit the upper and lower positions of the chain 3, preventing shaking during disassembly and ensuring the stability of the chain 3 during disassembly. By observing the relative position of the top rod 16 and the pin on the chain 3, the rotating screw block 22 is rotated. When the rotating screw 22 rotates, it drives the second adjusting screw 25 to rotate and adjust. When the second adjusting screw 25 rotates, it drives the outer moving block 23 to move and adjust. When the moving block 23 moves, it drives the support box 11 to move on the connecting support box 10. The support box 11 drives the top rod 16 to move, adjusting the position between the top rod 16 and the pin of the disassembly chain 3. By rotating the second rotating handwheel 15, the second rotating handwheel 15 drives the first adjusting screw 12 to rotate. When the first adjusting screw 12 rotates, it moves and adjusts the outer top plate 13. The top plate 13 moves inside the support box 11 and slides on the outer side of the second limiting slide bar 14. The top plate 13 drives the top rod 16 on one side to move outward. The top rod 16 pushes the pin connected to the chain 3 until it is pushed out from another opening 17, so that the sprocket 2 can be disassembled.

[0028] Please see Figures 1 to 4The inner fixed box 4 is equipped with a bidirectional lead screw 5, which is rotatably mounted inside. The outer side of the bidirectional lead screw 5 is symmetrically threaded with a movable slide plate 6. The movable slide plate 6 is slidably connected to the inner fixed box 4. The movable slide plate 6 is symmetrically mounted with a first limiting slide rod 7 inside. The first limiting slide rod 7 is fixedly connected to the inner fixed box 4. A first rotating handwheel 8 is rotatably mounted on one side of the inner fixed box 4. One end of the bidirectional lead screw 5 is fixedly connected to the first rotating handwheel 8.

[0029] It is understood that in this utility model, the first rotating handwheel 8 rotates the bidirectional lead screw 5. When the bidirectional lead screw 5 rotates, it drives the outer movable slide plate 6 to move and adjust. The movable slide plate 6 drives the movable base 9, the connecting support box 10, and the clamping positioning plate 20 to move. The clamping positioning plate 20 clamps and limits the two sides of the chain 3.

[0030] Please see Figure 4 The support box 11 has a first adjusting screw 12 rotatably mounted inside. The outer side of the first adjusting screw 12 is threadedly connected to a top plate 13. The top plate 13 is slidably connected to the support box 11. One end of the top rod 16 is fixedly connected to the top plate 13. The top plate 13 has a second limiting slide rod 14 symmetrically slidably mounted inside. The second limiting slide rod 14 is fixedly connected to the support box 11. A second rotating handwheel 15 is rotatably mounted on one side of the support box 11. One end of the first adjusting screw 12 is fixedly connected to the second rotating handwheel 15.

[0031] It is understood that in this utility model, the No. 2 rotating handwheel 15 rotates the No. 1 adjusting screw 12. When the No. 1 adjusting screw 12 rotates, it drives the outer top plate 13 to move and adjust. The top plate 13 drives the top rod 16 to move. The top rod 16 pushes out the pin connected inside the chain 3, which is convenient for disassembly.

[0032] Please see Figure 4 The connecting support box 10 is internally equipped with a second adjusting screw 25, and the outer side of the second adjusting screw 25 is threadedly connected to a moving block 23. The moving block 23 is slidably connected to the connecting support box 10, and the top of the moving block 23 is fixedly connected to the support box 11.

[0033] It is understood that this utility model adjusts the position between the top rod 16 and the pin by rotating the second adjusting screw 25, which in turn moves the outer moving block 23, and the moving block 23 moves the support box 11.

[0034] Please see Figure 4 A rotating screw block 22 is rotatably provided on one side of the connecting support box 10. One end of the second adjusting screw 25 is fixedly connected to the rotating screw block 22. A third limiting slide rod 24 is symmetrically slidably provided inside the moving block 23. The third limiting slide rod 24 is fixedly connected to the connecting support box 10.

[0035] It is understood that this utility model adjusts the second adjusting screw 25 by rotating the screw block 22, thereby adjusting the outer moving block 23 of the second adjusting screw 25.

[0036] Please see Figures 1 to 3 Multiple fixed support plates 19 are symmetrically fixed to the top of the outer support shell 1. Limiting rods 18 are slidably arranged inside the fixed support plates 19, and one end of the limiting rods 18 is fixedly connected to the clamping positioning plate 20.

[0037] It is understood that when the clamping positioning plate 20 is adjusted and moved, the limiting rod 18 on one side moves, and the limiting rod 18 slides with the fixed support plate 19, thereby improving the adjustment stability of the clamping positioning plate 20.
