A limiting protrusion 4221 can be convexly provided on a side wall of the second telescopic frame 422 facing the limiting clamping plate 4214. When the second telescopic frame 422 slides in the telescopic sliding groove, the limiting protrusion 4221 can be engaged in the limiting groove to limit the first telescopic frame 421 and the second telescopic frame 422, thereby limiting the relative positions of the two mounting seats 410.
[0088] In other embodiments, there are multiple limit card plates 4214, and the multiple limit card plates 4214 are arranged at intervals along the left and right directions. The limit slots on the multiple limit card plates 4214 can adjust the distance between the two mounting seats 410 to adapt to various types of door bodies 20. The distance between the two guide rails 440 can also be adjusted so that the guide rail bracket 400 can adapt to various types of refrigeration compartments 110.
[0089] In some embodiments, the distance between two adjacent limiting grooves can be determined according to various types of refrigeration equipment to be produced, thereby effectively improving the commonality of parts and reducing the production cost of refrigeration equipment.

[0095] In other embodiments, the first telescopic frame 421 and the second telescopic frame 422 can be sleeve structures.
[0096] In some embodiments, the mounting base 410 and the telescopic frame 420 are integrally formed, thereby effectively improving the structural strength of the guide rail structure 30 to improve the reliability and stability of the refrigeration equipment.
[0097] In other embodiments, the first telescopic frame 421 and the second telescopic frame 422 can also be connected by means of a snap connection, a threaded connection, a pin connection, etc.
[0098] In some embodiments, in the front-to-back direction, the telescopic frame 420 is located at the front side of the rear side of the mounting seat 410, so that the mounting seat 410 is attached to the rear plate 220, so as to facilitate the connection between the mounting seat 410 and the guide rail 440. When the foaming filling layer is foaming, the foaming filling layer can be filled between the telescopic frame 420 and the rear plate 220, thereby further improving the connection strength and reliability between the guide rail structure 30 and the door body 20.
[0099] See also Figures 7 to 14 In this embodiment, a connecting frame 430 may be provided on the opposite side of the two mounting seats 410. One side of the connecting frame 430 may be connected to the mounting seat 410, and a limiting hook 431 is convexly provided on the other side of the connecting frame 430. The limiting hook 431 is arranged opposite to the limiting bayonet 233, so that the connecting frame 430 can be connected to the side plate 230, so that the mounting seat 410 can be connected and limited on the door body 20.
[0100] In some embodiments, the limiting hook 431 is disposed at the rear side of the connecting frame 430. The limiting hook 431 is matched with the limiting opening 233 of the second bending portion 232. When the foaming filling layer foams, the foaming filling layer can be filled between the limiting hook 431 and the second bending portion 232 to improve the connection strength between the connecting frame 430 and the two side panels 230, thereby improving the structural strength and stability between the guide rail structure 30 and the door body 20.
[0101] See also Figures 5 to 10 In this embodiment, the guide rail 440 can be located at the rear side of the rear plate 220. The front end of the guide rail 440 can be against the rear plate 220. The front end of the guide rail 440 is provided with a guide groove 441 relative to the guide column 411, so that the front end of the guide rail 440 can be engaged with the mounting seat 410, thereby facilitating the positioning and installation of the guide rail 440.
[0102] The front end of the guide rail 440 can pass through the screw hole 412 on the mounting seat 410 to be detachably connected to the mounting seat 410, thereby improving the connection strength between the guide rail 440 and the mounting seat 410.
[0103] In some embodiments, a rolling pulley 442 may be provided at the lower rear end of the guide rail 440. The rolling pulley 442 may be slidably supported on the rolling chute, thereby facilitating the guide rail 440 to slide in the refrigeration compartment 110, thereby improving the movement efficiency of the door body 20 and the guide rail structure 30.
[0104] See also Figures 2 to 4 In this embodiment, the refrigeration device may further include a drawer 50, which is disposed between the two guide rails 440. The drawer 50 can move synchronously with the door body 20 and the guide rail structure 30. The connection structure of the drawer 50 and the guide rail 440 may refer to the structure of the drawer 50 in the relevant refrigeration device.
[0105] See also Figures 1 to 14 In the present invention, there are many types of refrigeration equipment, resulting in various types of refrigeration chambers 110 and door bodies 20. When the refrigeration equipment is in production, the mounting base 410, the telescopic frame 420 and the connecting frame 430 are placed in the foaming space 270. Then, the first telescopic frame 421 and the second telescopic frame 422 are adjusted to adjust the distance between the two mounting frames.
[0106] When the distance between the two mounting frames is determined and the limiting protrusion 4221 is engaged in the limiting groove, the mounting seat 410 is moved toward the second bending portion 232 so that the limiting hook 431 is engaged in the limiting slot 233 , and the mounting seat 410 is limited on the two side plates 230 .
[0107] After that, the rear plate 220 is connected to the two first bent portions 231. The rear plate 220 is attached to the rear side of the mounting seat 410. The guide column 411 passes through the rear plate 220. After the upper cover plate and the lower cover plate are assembled, a foam filling layer is filled to improve the connection strength between the mounting frame, the telescopic rod and the connecting rod and the door body 20. The reliability and stability of the door body 20 and the guide rail structure 30 are guaranteed.
[0108] Finally, the guide rail 440 is engaged with the guide column 411 through the guide groove 441, the front end of the guide rail 440 is attached to the rear plate 220, and the guide rail 440, the rear plate 220 and the mounting seat 410 are threadedly connected, so that the guide rail structure 30 is firmly connected to the door body 20.
[0109] The present application optimizes the guide rail structure 30 of the refrigeration equipment so that the guide rail structure 30 can be adapted to various types of door bodies 20 and refrigeration compartments 110, thereby improving the universality of the guide rail structure 30 and reducing the production cost of the refrigeration equipment.
[0110] In the present application, when different types of refrigeration equipment are produced and assembled, the guide rail structure 30 is accommodated in the door body 20. The distance between the two guide rails 440 is adjusted by moving the two guide rail brackets 400 toward or away from each other. After the two guide rail brackets 400 are abutted and limited to the door body 20, they can adapt to different types of refrigeration compartments 110. Thus, the door body 20 and the guide rail structure 30 can slide in and out of the box body 10. The guide rail structure 30 can be applied to the production of various types of refrigeration equipment, improve the commonality of refrigeration equipment parts, and effectively reduce the production cost of refrigeration equipment.
