[0024] See also Figure 1-7 The utility model provides a roller chain auxiliary installation assembly, including a roller chain body 102 arranged between two sets of sprockets 101, a fan-shaped cover 2 and a mounting plate 3. The fan-shaped cover 2 is provided with a transmission assembly for transmitting the sprocket 101, and the mounting plate 3 is provided with a limit assembly for connecting and installing with the sprocket 101.

[0025] The transmission assembly includes a mounting frame 401 fixed to the interior of the sector cover 2, a mounting shaft 402 is rotatably connected to the mounting frame 401, a rubber roller 403 is fixed to the mounting shaft 402 for contacting the outer side of the sprocket 101, and a rotating assembly for rotating the mounting shaft 402 is provided between the sector cover 2 and the mounting plate 3;

[0026] It should be noted here that: during the installation of the roller chain between the two sets of sprockets 101, the installation of the roller chain body 102 between the two sets of sprockets 101 is completed through the mutual cooperation of components such as the transmission assembly, the limit assembly and the rotating assembly. During the entire installation process, the operation is simple and the implementation is convenient, which improves the installation efficiency of the roller chain body 102 between the two sets of sprockets 101. At the same time, the operator's hands do not directly contact the sprockets 101, which facilitates safer installation operations of the roller chain.

[0027] The rotating assembly includes an installation box 501 fixed to the outside of the fan-shaped cover 2, a rotating shaft 502 is rotatably connected to the installation box 501, a linkage assembly for assisting linkage is provided between the rotating shaft 502 and the installation shaft 402, a winding wheel 503 is fixed to the rotating shaft 502, a pull rope 504 is wound around the winding wheel 503, one end of the pull rope 504 is fixed to one side of the installation plate 3, and a reset assembly for assisting the rotating shaft 502 to reset after rotation is provided between the rotating shaft 502 and the installation box 501;

[0028] It should be noted here that: after the mounting plate 3 and the roller chain body 102 are limitedly installed, the roller chain body 102 connected to the mounting plate 3 is pushed so that it moves toward and engages with the other group of sprockets 101. In the process of pushing the mounting plate 3, the pulling action of the pull rope 504 causes the winding wheel 503 and the rotating shaft 502 to rotate under force.

[0029] The linkage assembly includes a first gear 601 and a second gear 602 fixed to the mounting shaft 402 and the rotating shaft 502 respectively, and the first gear 601 and the second gear 602 are meshed with each other;

[0030] It should be noted that during the rotation of the rotating shaft 502 , the first gear 601 and the second gear 602 are meshed with each other, so that the mounting shaft 402 and the rubber roller 403 on the mounting shaft 402 are rotated under force.

[0031] The reset assembly includes a baffle 701 fixed on the rotating shaft 502, and a torsion spring 702 is sleeved on the rotating shaft 502. The two ends of the torsion spring 702 are respectively connected to the baffle 701 and the inner wall of the installation box 501;

[0032] It should be noted that during the rotation of the rotating shaft 502 , the connecting function of the baffle 701 causes the torsion spring 702 to deform and generate elastic force, and the elastic force of the torsion spring 702 facilitates the reset rotation of the rotating shaft 502 after rotation.

[0033] The limit assembly includes two sets of clamping plates 801 arranged on the mounting plate 3. The mounting plate 3 is provided with an elastic assembly for elastically connecting the clamping plates 801. The two sets of clamping plates 801 are provided with inclined surfaces 802 for resisting the sprocket 101 for transmission.

[0034] It should be noted here that: the mounting plate 3 is pushed toward other positions of the roller chain body 102. During the pushing process, the two sides of the roller chain body 102 are respectively against the inclined surfaces 802 of the two groups of splints 801. During the offset process, the two groups of splints 801 are pushed to move away from each other. After the mounting plate 3 is pushed, the elastic component is respectively offset against the two groups of splints 801, so that one end of the two groups of splints 801 after contraction are respectively offset against the two sides of the roller chain body 102. Through the offset and extrusion effect of the two groups of splints 801 against the two sides of the roller chain body 102, the mounting plate 3 is limitedly connected to the roller chain body 102.

[0035] The elastic component includes a fixing plate 901 fixed to the mounting plate 3, and a plurality of sleeves 902 are fixed to the fixing plate 901. A slide rod 903 is slidably connected to the sleeve 902. One end of the slide rod 903 is fixed to the clamping plate 801. A spring 904 is sleeved on the outer side of the sleeve 902.

[0036] It should be noted here that the sleeve 902 and the slide rod 903 between the fixed plate 901 and the splint 801 can assist in guiding the expansion and contraction of the splint 801 after it is subjected to force, and the spring 904 can facilitate the squeezing and pushing of the splint 801 after it is subjected to force and contraction.

[0037] A mounting pin 10 for driving the mounting plate 3 is fixed to the lower end of the mounting plate 3;

[0038] It should be noted here that the installation pin 10 facilitates the pushing operation of the installation plate 3 .

[0039] Working principle: During the installation of the roller chain between two sets of sprockets 101, part of the roller chain body 102 is pre-mounted on one of the sprockets 101, so that part of the roller chain body 102 is in meshing engagement with one of the sprockets 101;

[0040] After the sleeve is completed, the sector cover 2 is sleeved on the outer side of the roller chain body 102 after the sprocket 101 is engaged and connected. During the sleeve process, the rubber roller 403 inside the sector cover 2 is abutted against the outer side of the roller chain body 102. Figure 2 After the fan-shaped cover 2 is installed, the mounting plate 3 is pushed toward other positions of the roller chain body 102. During the pushing process, the two sides of the roller chain body 102 are respectively against the inclined surfaces 802 of the two groups of splints 801. During the offset process, the two groups of splints 801 are pushed to move away from each other. After the mounting plate 3 is pushed, the elastic components are respectively against the two groups of splints 801, so that one end of the two groups of splints 801 after contraction are respectively against the two sides of the roller chain body 102. Figure 6The mounting plate 3 is connected to the roller chain body 102 in a limited position by the two sets of clamping plates 801 respectively pressing against the two sides of the roller chain body 102;

[0041] After the mounting plate 3 and the roller chain body 102 are limitedly installed, the roller chain body 102 connected to the mounting plate 3 is pushed so as to move toward and engage with the sprocket 101 of the other group. In the process of pushing the mounting plate 3, the pulling action of the pull rope 504 causes the winding wheel 503 and the rotating shaft 502 to rotate under force. In the process of rotating the rotating shaft 502, the mutual meshing transmission between the first gear 601 and the second gear 602 causes the mounting shaft 402 and the rubber roller 403 on the mounting shaft 402 to rotate under force. Because the rubber roller 403 is against the outer side of the roller chain body 102, in the process of rotating the rubber roller 403 The roller chain body 102 is transmitted through the friction between the rubber roller 403 and the outer side of the roller chain body 102. By transmitting the roller chain body 102 and pushing the corresponding position of the roller chain body 102 to engage with the other set of sprockets 101, the roller chain body 102 is clamped between the two sets of sprockets 101 and is in an engaged state, completing the installation of the roller chain body 102 between the two sets of sprockets 101. During the entire installation process, the operation is simple and the implementation is convenient, which improves the installation efficiency of the roller chain body 102 between the two sets of sprockets 101. At the same time, the operator's hands do not directly contact the sprockets 101, which facilitates a safer installation operation of the roller chain.
