DETAILED DESCRIPTION
[0029] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiments.
[0030] As Figures 1-5 Indicated, the utility model provides a technical scheme: a kind of roller chain disassembly mechanism, comprising:
[0031] Datum strip seat 1;
[0032] Adjusting and disassembling mechanism 2, adjusting and disassembling mechanism 2 is set in the bottom of datum strip seat 1, adjusting and disassembling mechanism 2 is used to facilitate user to exert vertical disassembly force;
[0033] Elastic sheet connecting mechanism 3, elastic sheet connecting mechanism 3 is set on adjusting and disassembling mechanism 2, elastic sheet connecting mechanism 3 is used to grab elastic sheet.
[0034] As one implementation method in this embodiment, such as Figure 1 As shown, a limiting block 11 is fixedly connected to the front of the reference bar seat 1, a rubber plate 12 is fixedly connected to the inner wall of the reference bar seat 1, and a handle 13 is fixedly connected to the back of the reference bar seat 1. Through the design of the limiting block 11, the reference bar seat 1 can be moved and limited to the back of the pin, which is convenient for manual positioning work. Through the design of the handle 13, it is convenient for the user to pick up the reference bar seat 1. Through the design of the rubber plate 12, the reference bar seat 1 and the pin are flexibly connected, ensuring the safety of the pin.
[0035] As one implementation method in this embodiment, such as Figure 2 As shown, the adjustment and disassembly mechanism 2 includes a fixed block 21, which is fixedly installed at the bottom of the reference strip seat 1. A sliding rod 22 is slidably connected to the inner wall of the fixed block 21. A movable block 23 is fixedly installed at the front end of the sliding rod 22. A one-way screw 24 is threadedly connected to the inner wall of the fixed block 21. The front end of the one-way screw 24 is rotatably connected to the back of the movable block 23. A connecting plate 25 is fixedly installed at the back end of the one-way screw 24. A rotating rod 26 is rotatably connected to the back of the connecting plate 25. After the reference strip seat 1 is attached to the back of the pin and the elastic metal sheet connecting mechanism 3 is connected to the elastic metal sheet, the connecting plate 25 is manually rotated from the rotating rod 26, thereby driving the one-way screw 24 to rotate within the fixed block 21. By limiting the movable block 23 with the sliding rod 22, the elastic metal sheet connecting mechanism 3 can be driven to translate away from the reference strip seat 1. By applying a vertical force to the elastic metal sheet relative to the pin, the elastic metal sheet can be pulled out from the end of the pin.
[0036] As one implementation method in this embodiment, such as Figure 3 As shown, the elastic metal sheet connecting mechanism 3 includes a first support block 31, which is fixedly installed on the top of the movable block 23. A vertical arm 32 is fixedly installed on the top of the first support block 31, and a second support block 33 is fixedly installed on the top of the vertical arm 32. A bidirectional lead screw 34 is rotatably connected between adjacent sides of the first support block 31 and the second support block 33. A rotating handle 38 located on the top of the second support block 33 is fixedly connected to the top of the bidirectional lead screw 34. A pair of sliding connections are made on the outer walls of the vertical arm 32 and the bidirectional lead screw 34. The slider 35 is a symmetrical slider 35. A hook 36 is fixedly connected to the back of the slider 35, and a rubber pad 37 is fixedly connected to the front of the hook 36. During adjustment, the user can manually rotate the handle 38 to drive the bidirectional lead screw 34 to rotate, thereby causing the two symmetrical sliders 35 to slide simultaneously on the vertical arm 32 and the bidirectional lead screw 34 to move towards each other. This allows the hook 36 to be connected to the elastic metal sheet, facilitating disassembly. The design of the rubber pad 37 ensures a flexible connection between the hook 36 and the elastic metal sheet, guaranteeing the safety of the elastic metal sheet.
[0037] Working principle: When using, first hold handle 13 and move the structure to adjust it as follows. Figure 4 Then, manually rotate the connecting plate 25 from the rotating rod 26 to cause the elastic metal sheet connecting mechanism 3 to move backward as a whole. Next, manually rotate the handle 38 to drive the bidirectional lead screw 34 to rotate, thereby causing the two symmetrical sliders 35 to slide simultaneously on the vertical arm 32 and the bidirectional lead screw 34 to move towards each other, so that the hook 36 is connected to the elastic metal sheet. Then, rotate the connecting plate 25 again to cause the elastic metal sheet connecting mechanism 3 to move away from the reference bar seat 1 as a whole, so that the elastic metal sheet can be safely pulled out from the end of the pin.
[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
