Technical Field
[0001] The utility model relates to the field of chain shaft sleeve equipment, in particular to an aluminum chain shaft sleeve device which is easy to assemble and disassemble. Background Art
[0002] Chains are divided into four types according to their different uses and functions: transmission chains, conveyor chains, traction chains and special chains. We can see from the above chain structures that most chains are composed of chain plates, chain pins, bushings and other components. The bushing is the position where the friction is most serious, so it is necessary to disassemble and replace the bushing.
[0003] According to the patent document with the existing publication number CN218510093U, a chain shaft sleeve that is easy to load and unload is disclosed, which includes a chain body, the chain body includes a chain shaft, and shaft sleeve bodies that are compatible with it are sleeved on both sides of the chain shaft. The shaft sleeve body is composed of two identical semicircular shaft sleeve assemblies, and the upper and lower end faces of the shaft sleeve assembly are respectively provided with grooves and protrusions. The upper and lower parts of the shaft sleeve assembly are respectively symmetrically provided with threaded holes and countersunk holes. Screws are commonly provided in the corresponding threaded holes and countersunk holes. When in use, this technical solution can quickly and conveniently fit and position the shaft sleeve assembly through the arrangement of grooves and protrusions, thereby facilitating the alignment of the countersunk holes and threaded holes, thereby facilitating the fitting installation of the shaft sleeve assembly. Regarding the above technical solution, although this solution realizes fitting installation, the screws cannot be limited and fixed after being fixed, which is inconvenient during use.

When in use, after the fixing bolt is installed inside the fixing hole, the limiting bolt is installed in the limiting hole from the top, and the limiting bolt moves to the side of the limiting ring seat. The limiting bolt limits and fixes the limiting ring seat to prevent the fixing bolt from moving inside the fixing hole and causing the equipment to loosen.
[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: an aluminum chain sleeve device that is easy to load and unload, comprising a support plate, a fixed plate movably installed between the support plates, a sleeve installed between the fixed plates, the sleeve being installed on the fixed plate through a fixing pin, an opening being opened on the support plate, both ends of the fixing pin being movably installed inside the opening, the sleeve comprising a fixed seat and a movable seat, a fixed hole being opened on the fixed seat, and a fixing bolt being rotatably installed inside the fixing hole.
[0006] Furthermore, a limiting hole is formed on the movable seat, and a limiting bolt is rotatably installed inside the limiting hole.
[0007] Furthermore, a threaded ring seat and a limiting ring seat are respectively fixed on the fixing bolt, and the limiting ring seat is movably installed on one side of the limiting bolt.
[0008] Furthermore, arc-shaped grooves are formed on the inner walls of the movable seat and the fixed seat, and balls are movably installed inside the arc-shaped grooves.
[0009] Furthermore, arc-shaped holes are opened between the arc-shaped grooves, and heat dissipation holes are installed between the arc-shaped holes.
[0010] Furthermore, the fixed seat and the movable seat are both semicircular seats, and anti-slip grooves are provided on the inner walls of the movable seat and the fixed seat.
[0011] Beneficial effects of the utility model:
[0012] 1. This is an aluminum chain sleeve device that is easy to assemble and disassemble. When in use, after the fixing bolt is installed inside the fixing hole, the limit bolt is installed in the limit hole from the top, and the limit bolt moves to the side of the limit ring seat. The limit bolt limits and fixes the limit ring seat to prevent the fixing bolt from moving inside the fixing hole and causing the equipment to loosen.
[0013] 2. An aluminum chain sleeve device that is easy to assemble and disassemble. The arc hole transfers the high temperature generated inside the arc groove to the inside of the heat dissipation hole. The heat dissipation hole removes the high temperature generated by the friction of the ball, and after removal, the entire sleeve is cooled. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figures 1 to 3 The utility model provides a technical solution: an aluminum chain sleeve device that is easy to load and unload, comprising a support plate 1, a fixed plate 2 movably installed between the support plates 1, a sleeve 3 installed between the fixed plates 2, the sleeve 3 is installed on the fixed plate 2 through a fixing pin 5, an opening 4 is opened on the support plate 1, both ends of the fixing pin 5 are movably installed inside the opening 4, the sleeve 3 comprises a fixed seat 7 and a movable seat 8, a fixing hole 11 is opened on the fixed seat 7, a fixing bolt 12 is rotatably installed inside the fixing hole 11, a limiting hole 9 is opened on the movable seat 8, a limiting bolt 10 is rotatably installed inside the limiting hole 9, the limiting bolt 10 is installed perpendicular to the fixing bolt 12, and the limiting bolt 10 performs secondary limit fixation on the limiting bolt 12.
[0020] In this embodiment, a threaded ring seat 13 and a limiting ring seat 14 are respectively fixed on the fixing bolt 12, and the limiting ring seat 14 is movably installed on one side of the limiting bolt 10. The inner walls of the movable seat 8 and the fixed seat 7 are both provided with arc grooves 15, and balls 16 are movably installed inside the arc grooves 15. Arc holes 17 are provided between the arc grooves 15, and heat dissipation holes 18 are installed between the arc holes 17. The fixed seat 7 and the movable seat 8 are both semicircular seats, and the inner walls of the movable seat 8 and the fixed seat 7 are both provided with anti-slip grooves, which cooperate with each other to avoid misalignment and shaking between the fixed seat 7 and the movable seat 8.
[0021] When the device is installed, the fixed seat 7 and the movable seat 8 are fitted on the fixing pin 5 from both sides. During installation, the fixing bolt 12 rotates inside the fixing hole 11, and the rotation causes one end of the fixing bolt 12 to be installed inside the movable seat 8. The threaded ring seat 13 cooperates with the thread of the inner wall of the fixing hole 11 to realize the installation and fixation of the fixing bolt 12. After the fixing bolt 12 is installed, the limiting bolt 10 is installed inside the limiting hole 9, and one end of the limiting bolt 10 is rotated and moved downward. After the limiting bolt 10 moves downward, it contacts one side of the limiting ring seat 14. The limiting bolt 10 cooperates with the limiting ring seat 14 to limit the fixing bolt 12 as a whole, effectively preventing the fixing bolt 12 from falling off from the fixing hole 11. In addition, when in use, the ball 16 rotates on the fixing pin 5 to generate high temperature, and the high temperature enters the interior of the arc hole 17 through the arc groove 15, and finally realizes the cooling use at the position of the arc groove 15 through the heat dissipation hole 18.
