Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shopping cart technology, and specifically relates to an anti-slip structure for shopping cart escalators. Background Technology
[0002] A supermarket shopping cart is a wheeled metal or plastic trolley whose core function is to facilitate customers in storing and transporting goods in the supermarket. It usually consists of a basket, a frame, casters, and a child seat, and has become an important tool in the modern retail industry. When the shopping cart is pushed onto an escalator, its specially designed wheels will precisely engage in the slots of the escalator steps. Once engaged, the lateral movement of the wheels is completely restricted, and the wheels will tightly mesh with the grooves of the slots to form a mechanical interlock.
[0003] Traditional anti-slip devices for shopping cart escalators typically use bolts to fix the axles. However, due to long-term use, wear and tear, aging, or the need for replacement can lead to extremely inconvenient disassembly processes, increasing maintenance costs and affecting the normal efficiency of the shopping cart. To address these issues, we provide an anti-slip structure for shopping cart escalators. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-slip structure for shopping cart escalators, in order to solve the problem mentioned in the background art that traditional anti-slip devices for shopping cart escalators usually use bolt fixing structures to fix the wheel axles. When wear and aging occur due to long-term use, or when replacement is needed, the disassembly process is extremely inconvenient, which not only increases maintenance costs, but also affects the normal use efficiency of the shopping cart.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shopping cart escalator anti-slip structure, including a bracket, a bushing snapped into the bottom of the bracket, a sliding sleeve threaded to both ends of the bushing, a slot adapted to the sliding sleeve at the bottom of the bracket, a spring sleeved inside the bushing, a rod slidably sleeved inside the bushing, and limit blocks rotatably connected to both sides of the bracket, with insertion holes adapted to the rod inside the limit blocks.
[0006] Preferably, a rubber anti-slip wheel is fixedly fitted onto the surface of the bushing, and wheel plates are provided on both sides of the rubber anti-slip wheel.
[0007] Preferably, a bearing is fitted onto the surface of the bushing, a fixing plate is fixedly fitted onto the surface of the bearing, and a bolt is fitted onto the surface of the fixing plate, with one end of the bolt threadedly connected to the wheel plate.
[0008] Preferably, a rotating seat is fixedly connected to the top of the bracket, and a rotating shaft is rotatably connected inside the rotating seat.
[0009] This utility model has the following beneficial effects: This device employs a sliding engagement structure between the insert rod and the sliding sleeve, combined with the compression and reset action of the spring, allowing the insert rod to quickly disengage from the insertion hole. Combined with the rotational unlocking mechanism of the limiting block, it effectively achieves rapid disassembly and installation of the bushing. The device is easy to operate, significantly improving the maintenance efficiency of the shopping cart escalator anti-slip device, reducing the time and labor costs of disassembly and replacement, while enhancing the reliability and service life of the structure. It is suitable for commercial scenarios requiring frequent maintenance and possesses high practicality and economic efficiency. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.
[0013] Example 1:
[0014] refer to Figure 1-4 A shopping cart escalator anti-slip structure includes a bracket 1, a bushing 2 is snapped into the bottom of the bracket 1, and a sliding sleeve 3 is threaded to both ends of the bushing 2. The bottom of the bracket 1 has a slot 4 that matches the sliding sleeve 3. A spring 5 is sleeved inside the bushing 2. A plug rod 6 is slidably sleeved inside the bushing 2. Limiting blocks 7 are rotatably connected to both sides of the bracket 1. The limiting blocks 7 have insertion holes 8 that match the plug rod 6 inside.
[0015] Specifically, the device employs a sliding engagement structure between the insert rod 6 and the sliding sleeve 3, combined with the compression and reset action of the spring 5, enabling the insert rod 6 to quickly disengage from the insertion hole 8. Furthermore, the rotational unlocking mechanism of the limiting block 7 effectively achieves rapid disassembly and installation of the bushing 2. This device is easy to operate, significantly improves the maintenance efficiency of the shopping cart escalator anti-slip device, reduces the time and labor costs of disassembly and replacement, and enhances the reliability and service life of the structure. It is suitable for commercial scenarios requiring frequent maintenance and possesses high practicality and economy.
[0016] refer to Figure 3 A rubber anti-slip wheel 9 is fixedly fitted onto the surface of the bushing 2. Wheel plates 10 are provided on both sides of the rubber anti-slip wheel 9. By setting the rubber anti-slip wheel 9, it can be effectively used in conjunction with the escalator.
[0017] refer to Figure 3 A bearing 11 is fitted onto the surface of the bushing 2, and a fixing plate 12 is fixedly fitted onto the surface of the bearing 11. A bolt 13 is fitted onto the surface of the fixing plate 12, and one end of the bolt 13 is threadedly connected to the wheel plate 10. By setting the bearing 11, it can effectively cooperate with the wheel plate 10 for use.
[0018] refer to Figure 1 The top of the bracket 1 is fixedly connected to a rotating seat 14, and the rotating seat 14 is rotatably connected to a rotating shaft 15. By setting the rotating shaft 15, it can be effectively installed with the frame.
[0019] Brief description of the usage process: The user can push the insertion rod 6, which slides inside the sliding sleeve 3. The insertion rod 6 compresses the spring 5 and disengages from the insertion hole 8. Then, the user can rotate the limiting block 7 and pull the wheel plate 10 to disengage the sliding sleeve 3 from the slot 4, thereby effectively facilitating the quick disassembly of the bushing 2.
[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
