Description

Technical Field

[0001] The utility model relates to the technical field of chains, in particular to a chain disassembling device. Background Art

[0002] Chains are a common transmission and connection component in mechanical equipment, and are widely used in various industrial equipment, bicycles, motorcycles, automobiles, agricultural machinery, etc. Chains usually connect the links together through pins to form a continuous transmission structure. However, when the chain is worn, broken, or needs to be repaired or replaced, removing the pins on the chain becomes an important operation.

[0003] Traditional chain disassembly methods usually rely on manpower using simple tools such as welding rods and nails to knock the pins out of the chain links. This method has obvious drawbacks:

[0004] Since the pin of the chain is small in size and usually requires high precision to ensure the smooth operation of the chain, it takes a lot of time to knock the pin with simple tools, especially when the pin is tightly combined with the chain link, the disassembly process is more time-consuming; since the design of the chain pin is often to ensure that it will not fall off by itself during normal operation, its structure is usually relatively tight, and it is difficult to effectively disassemble it with simple tools, especially in the case of limited space such as the chain in the middle of the beam. The limited operating space further increases the difficulty of disassembly; when using welding rods, nails and other tools for knocking, due to improper operation or loss of tool control, it is easy to hit the hands or other parts, causing personal injury. In addition, the splashes generated during the knocking process may also cause pollution or damage to the surrounding environment; during the disassembly process, if the force is improper or the tool is not selected properly, it is easy to cause damage to the chain, such as deformation of the chain link, breakage of the pin, etc., thereby affecting the service life and transmission performance of the chain.

[0041] See also Figures 1 to 5 , this embodiment provides a chain 50 disassembly device, comprising:

[0042] A disassembly plate 10, wherein the disassembly plates 10 are two pieces, the two disassembly plates 10 are arranged opposite to each other, and a disassembly channel 11 for accommodating the chain 50 is provided between the two disassembly plates 10;

[0043] A connecting plate 20, wherein the connecting plate 20 is connected to the two disassembly plates 10;

[0044] A first through hole 12 is formed on one disassembly plate 10, and a second through hole 13 is formed on the other disassembly plate 10. The first through hole 12 and the second through hole 13 are arranged opposite to each other, and the second through hole 13 is used for the pin shaft on the chain 50 to pass through.

[0045] The disassembly assembly 30 is movably disposed in the first through hole 12, and the disassembly assembly 30 is used for disassembly. In some embodiments, the disassembly plate 10 and the connecting plate 20 are integrally formed.

[0046] There are two disassembly plates 10, and the two disassembly plates 10 are arranged opposite to each other. A gap adapted to the chain 50 is left between the two disassembly plates 10, and the gap is the disassembly channel 11, and the disassembly channel 11 is used to accommodate the chain 50 to be disassembled. Specifically, when the chain 50 needs to be disassembled, the chain 50 is placed in the disassembly channel 11; that is, when the chain 50 needs to be disassembled, the chain 50 is placed between the two disassembly plates 10. The disassembly channel 11 is adapted to the chain 50.

[0047] The connecting plate 20 is located on the top or side of the two disassembly plates 10, and is used to fix and connect the two disassembly plates 10, ensuring that the two disassembly plates 10 maintain a stable positional relationship during the disassembly process. Furthermore, the connecting plate 20 can also be placed between the two disassembly plates 10, that is, the two opposite sides of the connecting plate 20 are connected to one of the disassembly plates 10 respectively.

[0048] It should also be noted that in order to improve the overall strength and prevent the disassembly plate 10 and the connecting plate 20 from being damaged during the disassembly operation, the disassembly plate 10 and the connecting plate 20 are integrally formed so that the connecting plate 20 and the disassembly plate 10 form a "concave" shaped structure.

[0049] The first through hole 12 is formed through one of the disassembly plates 10, and the second through hole 13 is formed at a corresponding position on the other disassembly plate 10. The first through hole 12 and the second through hole 13 are arranged opposite to each other, so as to ensure that when the chain 50 is placed between the two disassembly plates 10 and the pins on the chain 50 are separated by force, the pins on the chain 50 can smoothly pass through the second through hole 13.

[0050] The disassembly assembly 30 is movably disposed in the first through hole 12, that is, the disassembly assembly 30 and; the disassembly assembly 30 generally includes a movable or rotatable component for applying an external force to the pin shaft, thereby realizing the separation of the pin shaft and the chain link.

[0051] In actual operation, the chain 50 is first placed in a preset position, that is, the chain 50 is placed in the disassembly channel 11, and the shaft pin on the chain 50 is aligned with the second through hole 13. Then, by operating the disassembly assembly 30, the end of the disassembly assembly 30 is extended or rotated out of the first through hole 12 until the end of the disassembly assembly 30 presses against the pin of the chain 50 and continues to extend; so as to apply an external force opposite to the connection direction of the chain link to the pin. This external force gradually increases until the connection between the pin and the chain link is broken and the pin is disengaged from the chain link.

[0052] Different from the prior art, the above technical solution allows the chain 50 to be placed in the disassembly channel 11 through the setting of the disassembly channel 11, thereby avoiding displacement of the chain 50 during disassembly; at the same time, through the setting of the second through hole 13 and the disassembly assembly 30, the pin shaft can be ejected by the disassembly assembly 30, thereby improving the disassembly efficiency and avoiding damage to the chain 50 caused by disassembly.

[0053] According to some embodiments of the present application, referring to Figure 1 to Figure 2 , the disassembly assembly 30 includes: a base 31 and an ejector pin 32;

[0054] The first through hole 12 is adapted to the base 31 , and the first through hole 12 is used to accommodate the base 31 . The ejector pin 32 is disposed at one end of the base 31 close to the second through hole 13 , and the ejector pin 32 is used to eject the pin shaft on the chain 50 .

[0055] The base 31 is a cylindrical structure, and the diameter of the base 31 is adapted to the diameter of the first through hole 12 , that is, the base 31 is slidably connected or threadedly connected to the first through hole 12 ; when in use, the base 31 is driven to slide in the first through hole 12 .

[0056] The diameter of the ejector pin 32 is smaller than the diameter of the base 31. Of course, in other embodiments, the diameter of the base 31 is equal to the diameter of the ejector pin 32. Preferably, the diameter of the ejector pin 32 is smaller than the diameter of the base 31, and the diameter of the first through hole 12 is larger than the diameter of the second through hole 13. The first through hole 12 is adapted to the base 31, and the second through hole 13 is adapted to the ejector pin 32. When the diameter of the first through hole 12 is not equal to the diameter of the second through hole 13, the relative arrangement of the two means that the centers of the two are arranged relative to each other.

[0057] The ejector pin 32 is disposed at one end of the base 31 close to the second through hole 13, and the ejector pin 32 is disposed at the center of the base 31. The ejector pin 32 moves synchronously with the base 31. Specifically, the ejector pin 32 is driven by the base 31 to support the pin shaft, and then the base 31 further applies force to make the pin shaft disengage from the chain 50.

[0058] In order to facilitate the application of force, according to some embodiments of the present application, refer to Figures 1 to 5 The disassembly assembly 30 further includes a push plate 33 , which is connected to the base 31 and is disposed at an end of the base 31 away from the ejector pin 32 .

[0059] The push plate 33 is disposed at one end of the base 31 away from the ejector pin 32 . When the chain 50 is placed at a preset position (the pin is aligned with the second through hole 13 ), the base 31 and the ejector pin 32 can be driven to move by pushing the push plate 33 .

[0060] In order to enable the pin to be completely pushed out, according to some embodiments of the present application, Figures 1 to 5 The diameter of the second through hole 13 is larger than the diameter of the ejector pin 32 , and the length of the ejector pin 32 is larger than the distance between the two disassembly plates 10 .

[0061] Specifically, when the ejector pin 32 ejects the pin, the ejector pin 32 is located at the original position of the pin, so that the pin is completely ejected from the chain 50; at the same time, since the aperture of the second through hole 13 is larger than that of the ejector pin 32, after the pin is ejected, the end of the ejector pin 32 can be placed in the second through hole 13.

[0062] According to some embodiments of the present application, referring to Figures 1 to 5 , also includes:

[0063] A sleeve 40 having a third through hole 41 extending therethrough, the sleeve 40 being disposed on a side of the first through hole 12 away from the second through hole 13, the sleeve 40 being connected to the disassembly plate 10 having the first through hole 12, the third through hole 41 being in communication with the first through hole 12, and the third through hole 41 being used to accommodate the disassembly assembly 30.

[0064] The sleeve 40 is used to improve the sliding stability of the base 31 to prevent the base 31 from tilting when sliding; specifically, the sleeve 40 is a tubular structure, and the diameter of the inner tube of the sleeve 40 (i.e., the third through hole 41) is equal to the aperture of the first through hole 12, so that the base 31 can slide in the sleeve 40 and the first through hole 12.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application 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 replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
