AI Technical Summary
Existing wardrobe folding wheels are prone to derailment during use due to wear on the wheels or deformation of the slide rail, especially when children use them or when they push the door incorrectly. Furthermore, the existing design cannot guarantee both convenience and derailment prevention during installation.
The main pulley and auxiliary pulley adopt a triangular layout structure, with the main pulley and auxiliary pulley vertically opposite each other and fixedly installed under the pulley seat by a fixing seat, forming an inverted triangular layout. This ensures that the height of the main pulley is adapted to the profile slide rail, and the auxiliary pulley plays a buffering role when the main pulley derails.
It effectively prevents wardrobe folding wheels from derailing during use, ensures smooth gliding, reduces noise, and has a simple structure, low cost, and is easy to install.

Abstract
Description
Technical Field
[0001] The utility model relates to a folding wheel for a wardrobe, in particular to an anti - falling folding wheel with a main pulley and an auxiliary pulley arranged in a triangular layout. Background Art
[0002] One of the common installation methods for wardrobes on the market is to install them with flat - push doors. Most of the flat - push door installations use a hanging method. However, the folding wheels for hanging - installed wardrobes on the market all use the self - weight of the door to make the pulleys of the folding wheels slide on the slide rail. This design provides convenience during installation. But when the folding wheel is used for a long time and the pulleys are worn, or the slide rail is slightly deformed by external force, it can slide normally during normal flat - pushing. However, if it is used by children or the way of pushing the door is not correct with an additional longitudinal thrust, the folding wheel is likely to get derailed. And it is precisely the problem that the folding wheel needs to solve to eliminate such derailment hazards while being convenient during installation. Content of the Utility Model
[0003] The purpose of the utility model is to provide a folding wheel for a wardrobe. It adds an auxiliary pulley under the main pulley, and the main pulley and the auxiliary pulley are arranged in a triangular layout structure, effectively preventing the pulley from getting derailed when pushing the door.
[0004] The technical solution of the utility model is based on a pulley arm, a pulley seat, a main pulley, a fixed seat, and an auxiliary pulley. The pulley seat is fixedly installed on the top column of the pulley arm. On the top of the front of the pulley seat, two main pulleys are arranged horizontally. A fixed seat is fixedly installed on the front of the pulley seat below the main pulley through screws. The auxiliary pulley is installed on the fixed seat. The main pulley and the auxiliary pulley are vertically opposite up and down, and form an inverted triangular layout.
[0005] The distance between the main pulley and the auxiliary pulley of the utility model up and down is adapted to the height of the profile slide rail, preventing the folding wheel from falling off when sliding on the profile. The fixed seat is fixedly installed on the pulley seat through two screws, preventing the auxiliary pulley from being easily loosened when the folding wheel is used.
[0006] The working principle of the present utility model is that the main pulley and the auxiliary pulley are vertically opposite to each other and are installed and fixed in an inverted "pin" - shaped layout. During installation, since the distance between the upper and lower parts of the main pulley and the auxiliary pulley is adapted to the height of the profile slide rail, it can be conveniently buckled into the slide rail for installation, and there is no difference from the installation method of the common wardrobe folding wheel. When the longitudinal force applied to the sliding door is not sufficient to cause the main pulley to derail, because the auxiliary pulley also has rolling ability, the sliding door can slide normally to open or close. When the longitudinal force applied to the sliding door is sufficient to cause the main pulley to derail, at the moment when the main pulley is about to derail, the auxiliary pulley touches the bottom of the profile slide rail, restricting the derailment of the main pulley and playing a buffering role to protect the main pulley from damage and the slide rail from deformation. Only an accurate pure longitudinal force can buckle the wardrobe folding wheel onto the profile slide rail. In this way, while achieving convenient installation, it effectively prevents the phenomenon of accidental derailment.
[0007] The advantages of the present utility model are simple structure, low manufacturing cost, low noise, smooth sliding, and it can effectively prevent the accidental derailment of the sliding door. Brief Description of the Drawings
[0008] Figure 1 It is a schematic three - dimensional structure diagram of the present utility model installed on the profile;
[0009] Figure 2 It is a schematic three - dimensional structure diagram of the whole of the present utility model. Detailed Implementation Modes
[0010] According to Figure 1 、 Figure 2 As shown, based on the pulley arm 1, pulley seat 2, main pulley 3, fixed seat 4, and auxiliary pulley 5 of the present utility model, the pulley seat 2 is fixedly installed on the top column of the pulley arm 1. On the front top of the pulley seat 2, two main pulleys 3 are arranged horizontally. On the front of the pulley seat 2, below the main pulley 3, a fixed seat 4 is fixedly installed by screws. The auxiliary pulley 5 is installed on the fixed seat. The main pulley 3 and the auxiliary pulley 5 are vertically opposite to each other up and down, and form an inverted "pin" - shaped layout. The distance between the upper and lower parts of the main pulley 3 and the auxiliary pulley 5 is adapted to the height of the profile slide rail to prevent the folding wheel from falling off when sliding on the profile. The fixed seat 4 is fixedly installed on the pulley seat by two screws to prevent the auxiliary pulley 4 from being easily loosened during the use of the folding wheel.
