[0035] Reference Figures 1 to 5 The grease cup assembly of the first embodiment of the utility model comprises an oil filling cup 100, a stop plate 200 and an elastic structure 300, referring to Figure 1 , Figure 2As shown, the oil filling cup 100 has a accommodating cavity 110 for placing the grease bag, the abutment plate 200 and the elastic structure 300 are both installed in the accommodating cavity 110, the abutment plate 200 is used to contact the grease bag, and the two ends of the elastic structure 300 are respectively against the bottom wall of the oil filling cup 100 and the abutment plate 200, and the elastic structure 300 is used to push the abutment plate 200 to move away from the bottom wall of the accommodating cavity 110, that is, the elastic structure 300 is used to apply a force to the grease bag to squeeze the grease in the grease bag.

[0036] In the embodiment of the utility model, the side wall of the accommodating cavity 110 is provided with a strip groove 121; there are multiple strip grooves 121, and the multiple strip grooves 121 are evenly spaced around the circumference; the abutment plate 200 is provided with a radially protruding bayonet 210, and the bayonet 210 is slidably installed in the strip groove 121; there are multiple bayonet 210 corresponding to the strip groove 121. Specifically, the provision of multiple strip grooves 121 and bayonet 210 can ensure that the abutment plate 200 can always slide stably along the length extension direction of the oil filling cup 100, and the abutment plate 200 is not easy to deflect; the number of strip grooves 121 is preferably three or more, and the specific number can be determined according to the size of the oil filling cup 100. As the diameter of the oil filling cup 100 increases, the number of strip grooves 121 can be increased accordingly. The size of the strip groove 121 matches the size of the bayonet 210, the groove wall of the strip groove 121 extends toward the center direction of the accommodating cavity 110, and the bayonet 210 is arranged on the outer peripheral wall of the abutment plate 200 and extends in the radial direction of the abutment plate 200. By arranging the strip groove 121 on the side wall of the oil filling cup 100, arranging the bayonet 210 protruding radially on the abutment plate 200 to be slidably installed in the strip groove 121, and then arranging the elastic structure 300 to abut against the oil filling cup 100 and the abutment plate 200 respectively, the structure is simple and the manufacturing cost is low; by limiting the bayonet 210 through the strip groove 121, the abutment plate 200 can be prevented from being separated from the oil filling cup 100, thereby ensuring the stability of the grease cup assembly.

[0037] In the embodiments of the present invention, referring to Figures 1 to 3 As shown, the side wall of the accommodating cavity 110 is provided with a straight plate area 120, and the strip groove 121 is provided in the straight plate area 120. Specifically, the oil filling cup 100 is cylindrical, so the side wall of the oil filling cup 100 is a curved surface, and the surface of the straight plate area 120 is a plane. By providing the straight plate area 120 on the side wall of the oil filling cup 100, and then providing the strip groove 121 in the straight plate area 120, the difficulty of providing the strip groove 121 can be effectively reduced, and the consistency of multiple strip grooves 121 can be improved. In addition, since the surface of the straight plate area 120 is a plane, its outer surface is equivalent to being recessed compared to the curved surfaces on both sides. Therefore, during transportation or installation, the straight plate area 120 is less likely to be collided, thereby reducing the risk of deformation of the straight plate area 120, and ensuring that the abutment plate 200 can slide smoothly along the strip groove 121.

[0038] In one embodiment of the grease cup assembly of the present utility model, the side wall of the strip groove 121 is not provided with an opening 122. Figure 5 As shown, the support plate 200 is a circular plate, and the bayonet 210 extends outward along the radial direction of the support plate 200. As can be seen from the above, the groove wall of the strip groove 121 extends toward the center of the accommodating cavity 110, so the circular area of ​​the support plate 200 is smaller than the inner diameter of the oil filling cup 100. Therefore, even if the side wall of the strip groove 121 is not provided with an opening 122, the support plate 200 can be installed in the strip groove 121. When installing, the support plate 200 only needs to be tilted and placed in the accommodating cavity 110, and then the bayonet 210 can be aligned with the strip groove 121 and installed in the strip groove 121. In this installation method, since the side wall of the strip groove 121 is not provided with an opening 122, it is difficult for the support plate 200 to be separated from the strip groove 121, that is, the stability of the connection between the support plate 200 and the oil filling cup 100 is better.

[0039] In another embodiment of the grease cup assembly of the present invention, the groove wall of the strip groove 121 is provided with an opening 122, and the opening 122 is provided at one end of the strip groove 121 away from the bottom wall of the accommodating cavity 110. Figure 3 , Figure 4 As shown, the groove wall of the strip groove 121 is provided with an opening 122 , and the size of the opening 122 should be slightly larger than the size of the latch 210 . Such a design can effectively improve the installation efficiency of the abutment plate 200 and reduce the installation difficulty of the abutment plate 200 .

[0040] In the embodiment of the present invention, the elastic structure 300 includes a first elastic member 310 and a second elastic member 320, and the first elastic member 310 is sleeved on the outer periphery of the second elastic member 320. Figure 1 , Figure 2 As shown, the first elastic member 310 and the second elastic member 320 are preferably springs, which have a simple structure, low manufacturing cost, and long service life. The elastic structure 300 includes the first elastic member 310 and the second elastic member 320, which can serve as backup for each other and can simultaneously extend the service life of the first elastic member 310 and the second elastic member 320; in addition, the size of the first elastic member 310 is larger than the size of the second elastic member 320, that is, the first elastic member 310 and the second elastic member 320 have different action positions on the abutment 200, so the deformation of the abutment 200 can also be reduced.

[0041] In the embodiments of the present invention, referring to Figure 3As shown, the bottom wall of the accommodating cavity 110 is provided with a first retaining ring 111 and a second retaining ring 112, the first elastic member 310 is sleeved on the outer periphery of the first retaining ring 111, and the second elastic member 320 is sleeved on the outer periphery of the second retaining ring 112; the first retaining ring 111 is used to limit the first elastic member 310, and the second retaining ring 112 is used to limit the second elastic member 320. The first retaining ring 111 can be designed as a plurality of arc segments or a circular whole, and the second retaining ring 112 can also be set as a circular whole or a plurality of arc segments. The first retaining ring 111 is provided to limit the first elastic member 310, and the second retaining ring 112 is provided to limit the second elastic member 320, which can ensure the stability of the positions of the first elastic member 310 and the second elastic member 320, thereby improving the structural stability of the grease cup assembly.

[0042] Further, see Figure 5 As shown, in the embodiment of the utility model, the back plate 200 is provided with a third retaining ring 220 and a fourth retaining ring 230, the third retaining ring 220 corresponds to the first retaining ring 111, and the diameters of the third retaining ring 220 and the first retaining ring 111 are substantially equal; the fourth retaining ring 230 corresponds to the second retaining ring 112, and the diameter of the fourth retaining ring 230 is substantially equal to the diameter of the second retaining ring 112; that is, the third retaining ring 220 is also used to limit the first elastic member 310, and the fourth retaining ring 230 is also used to limit the first elastic member 310. The two elastic members 320 are limited, the first retaining ring 111 cooperates with the third retaining ring 220 to respectively limit the two ends of the first elastic member 310, the second retaining ring 112 cooperates with the fourth retaining ring 230 to respectively limit the two ends of the second elastic member 320, and the first retaining ring 111, the second retaining ring 112, the third retaining ring 220 and the fourth retaining ring 230 can effectively ensure that the first elastic member 310 and the second elastic member 320 can only be extended and retracted vertically, and are not prone to bending and other problems.

[0043] It should be noted that the heights of the first retaining ring 111, the second retaining ring 112, the third retaining ring 220 and the fourth retaining ring 230 should not be too high, as this will affect the volume of the grease bag that can be loaded into the accommodating cavity 110; at the same time, the heights of the first retaining ring 111, the second retaining ring 112, the third retaining ring 220 and the fourth retaining ring 230 should not be too low, and should at least play a role in limiting the first elastic member 310 and the second elastic member 320.

[0044] In the embodiment of the present invention, the center of the abutment plate 200 is recessed toward the bottom wall to form a protrusion 240, the fourth retaining ring 230 is disposed on the protrusion 240, and the second elastic member 320 abuts against the protrusion 240. Figure 5As shown, the protrusion 240 is provided and the second elastic member 320 is against the protrusion 240, which can effectively reduce the concave deformation of the center of the plate 200. Under the long-term action of the second elastic member 320, the center position of the plate 200 is easily deformed in a concave direction away from the bottom wall. By providing the protrusion 240 facing the bottom wall in advance, and the protrusion 240 is formed by the plate 200 being concave in the direction of the bottom wall, it is equivalent to giving the center position of the plate 200 an advance amount of deformation. Even if the protrusion 240 is partially deformed, the deformed part of the protrusion 240 will not contact the grease bag, and thus will not affect the grease bag in contact with the plate 200. In addition, compared with a flat plate 200, the protrusion 240 has a stronger anti-deformation ability, that is, the plate 200 will be less likely to deform.

[0045] In the embodiment of the present invention, a working hole 241 penetrating the abutment plate 200 is provided at the center of the abutment plate 200. Figure 1 , Figure 5 As shown, the operation hole 241 is provided to facilitate adjustment of the abutment plate 200. When the abutment plate 200 is deflected, a force is applied to the abutment plate 200 through the operation hole 241, so that the abutment plate 200 can be restored to a flat state.
