[0031] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figures 1 to 3 One embodiment of the present invention provides an adjustable height support wheel assembly, including: a height adjustment mechanism 10 and a support wheel mechanism 20;

[0032] The height adjustment mechanism 10 includes a top plate 11, a bottom plate 12, and multiple adjusting screws 13. The top of the top plate 11 is provided with a clearance groove 111, and the top plate 11 is also provided with a mounting part 112 for assembly with the frame 30 of the rail-mounted push-pull food cart. Multiple first through holes 113 are provided in the clearance groove 111, and multiple second through holes 121 are provided on the bottom plate 12. A limiting member 131 is provided at the top of the adjusting screw 13. The adjusting screw 13 passes through the first through hole 113 and the first through hole 121 respectively. The adjusting screw 13 is rotatably engaged with the first through hole 113 and threadedly engaged with the second through hole 121. The limiting member 131 is located in the clearance groove 111 and restricts the axial position of the adjusting screw 13 relative to the first through hole 113. The clearance groove 111 can hide the limiting member 131, so that when the top plate 11 is installed at the bottom of the frame 30 of the rail-mounted push-pull food cart, the limiting member 131 is less likely to interfere with the frame 30.

[0033] The support wheel mechanism 20 is installed at the bottom of the base plate 12. The height of the top plate 11 relative to the base plate 12 can be adjusted by rotating the adjusting screw 13, thereby adjusting the height of the frame 30 of the rail-mounted push-along dining cart. The structure is simple and the operation is convenient.

[0034] In some alternative embodiments, a limiting step 132 is formed on the side of the adjusting screw 13. The limiting step 132 is located at the bottom of the top plate 11. The limiting step 132 and the limiting member 131 cooperate to limit the position of the adjusting screw 13 relative to the first through hole 113 in the axial direction, thereby making the adjusting screw 13 stably limited on the top plate 11.

[0035] The structure of the support wheel mechanism 20 can be designed according to actual needs. For example, in some optional embodiments, the support wheel mechanism 20 includes a wheel plate 21, a wheel frame 22, and a wheel body 23. The wheel plate 21 is provided with a plurality of clearance holes 211. The wheel frame 22 is located at the bottom of the wheel plate 21, and the wheel body 23 is rotatably mounted on the wheel frame 22. The wheel plate 21 is located at the bottom of the base plate 12. The bottom end of the adjusting screw 13 passes through the clearance hole 211 and then protrudes from the bottom of the wheel plate 21. The clearance hole 211 prevents the adjusting screw 13 from being interfered with by the support wheel mechanism 20, making it convenient for the user to turn the adjusting screw 13 from below the wheel plate 21 using a tool.

[0036] In some alternative embodiments, at least a portion of the bottom end of the adjusting screw 13 is outside the projection range of the wheel frame 22 and the wheel body 23 in the projection direction from bottom to top. This prevents the wheel frame 22 and the wheel body 23 from obstructing the user from aligning the tool with the end of the adjusting screw 13, making it easier for the user to operate the adjusting screw 13. For example, in one embodiment, the bottom end of the adjusting screw 13 is provided with a flower-shaped groove. The user can use a screwdriver to engage with the flower-shaped groove of the adjusting screw 13 and then turn the screwdriver. The structure of the wheel frame 22 and the wheel body 23 can avoid the screwdriver, thus avoiding obstructing the operation of the screwdriver.

[0037] Please see Figure 4 In some alternative embodiments, the base plate 12 and the wheel plate 21 are detachably engaged by a plurality of first threaded locking members 24. The first threaded locking members 24 protrude from the bottom of the wheel plate 21. In the projection direction from bottom to top, at least a portion of the first threaded locking members 24 is located outside the projection range of the wheel frame 22 and the wheel body 23, thereby preventing the wheel frame 22 and the wheel body 23 from obstructing the user from using tools to align with the cap of the first threaded locking member 24, making it convenient for the user to operate the first threaded locking member 24. For example, in one embodiment, the cap of the first threaded locking member 24 is provided with a flower-shaped groove. The user uses a screwdriver to engage with the flower-shaped groove of the first threaded locking member 24 and then twists the screwdriver. The structure of the wheel frame 22 and the wheel body 23 can avoid the screwdriver, thus avoiding obstructing the operation of the screwdriver.

[0038] In some alternative embodiments, the mounting part 112 includes a plurality of mounting holes 1121 provided on the top plate 11 and a plurality of second threaded locking members 1122 corresponding to the mounting holes 1121. The second threaded locking members 1122 are used to assemble with the frame 30 of the rail-mounted push-type catering cart, so as to realize the detachable connection between the top plate 11 and the frame 30 of the rail-mounted push-type catering cart, which facilitates assembly and transportation.

[0039] Please see Figure 4In some alternative embodiments, in the projection direction from bottom to top, the second threaded locking member 1122 is located outside the projection range of the wheel plate 21, wheel frame 22, and wheel body 23, thereby preventing the wheel plate 21, wheel frame 22, and wheel body 23 from obstructing the user from aligning the tool with the cap of the second threaded locking member 1122, making it easier for the user to operate the second threaded locking member 1122. For example, in one embodiment, the cap of the second threaded locking member 1122 is provided with a flower-shaped groove. The user can engage the screwdriver with the flower-shaped groove of the second threaded locking member 1122 and then turn the screwdriver. The structure of the wheel frame 22 and the wheel body 23 can avoid the screwdriver, thus avoiding obstructing the operation of the screwdriver.

[0040] In this embodiment, the installation operations between the top plate 11 and the frame 30, the height adjustment operation of the adjusting screw 13, and the installation operations between the top plate 11 and the wheel plate 21 can all be performed using a screwdriver, enabling tool sharing and simplifying the installation process. Furthermore, the top plate 11, bottom plate 12, and wheel plate 21 can be disassembled, facilitating packaging and transportation.

[0041] Please see Figure 4 In some optional embodiments, clearance grooves 221 are provided on both sides of the wheel frame 22, and the shape of the base plate 12 matches that of the wheel plate 21, so that the wheel plate 21 can stably support the base plate 12. In the projection direction from bottom to top, a plurality of second threaded locking members 1122 are respectively arranged on both sides of the wheel frame 22, and at least partially located in the clearance grooves 221. The design of the clearance grooves 221 prevents the wheel plate 21 from obstructing the installation of the second threaded locking members 1122.

[0042] Please see Figure 5 Another embodiment of the present invention provides a rail-mounted push-pull dining cart, including: a frame 30 and a plurality of adjustable height support wheel assemblies as described above, wherein the top plate 11 of the adjustable height support wheel assembly is disposed at the bottom of the frame 30.

[0043] Please see Figure 6 In some alternative embodiments, the bottom of the rail-mounted push-along food cart is also provided with a mounting frame 31 and a cover plate 32 provided on the mounting frame 31. In the front-to-back direction, the cover plate 32 at least partially covers the adjustable height support wheel assembly, which is supported on the bottom of the frame 30, so that there is a gap between the bottom of the frame 30 and the ground. When the rail-mounted push-along food cart is put into the cabinet slot, the front side of the gap can be blocked by the cover plate 32, thereby preventing the adjustable height support wheel assembly from being seen, improving the aesthetics, and also preventing debris, garbage and other things from entering the gap between the bottom of the frame 30 and the ground.

[0044] The mounting bracket 31 is provided with an adjustment groove 33 extending vertically, and the baffle plate 32 is provided with an adjustment locking component 34. The adjustment locking component 34 is movably engaged with the adjustment groove 33, locking the baffle plate 32 onto the mounting component. The mounting component can be a threaded component such as a bolt, and can move vertically relative to the adjustment groove 33, allowing the height of the baffle plate 32 to be adjusted. After the height of the baffle plate 32 is adjusted, it is locked onto the mounting bracket 31 by the mounting component. While adjusting the height of the height-adjustable support wheel assembly, the height of the baffle plate 32 can also be adjusted, ensuring that the baffle plate 32 maintains a suitable distance from the ground, thereby preventing debris and garbage from entering between the bottom of the frame 30 and the ground.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
