[0003] In the prior art, the corner wheel device is usually directly installed on the door body for interfacing with the track, but in the actual use process, in order to facilitate the installation and subsequent disassembly, there is a certain gap between the corner wheel and the inner wall of the track, which leads to unstable movement of the door body and easy shaking; in addition, when used for a long time, some filament-like objects falling in the track are easy to be wound on the outer surface of the corner wheel, which not only affects the smooth rotation of the corner wheel, but also increases the resistance when the sliding door is moved, and reduces the use effect of the corner wheel device.

[0004] Therefore, there is a need for a corner wheel that increases the stability of the sliding door to solve the problem that the corner wheel and the inner wall of the track do not contact sufficiently, leading to unstable sliding door, and the outer surface of the corner wheel is easy to be wound with filament-like objects when used for a long time, leading to unsmooth rotation. UTILITY MODEL CONTENTS

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a corner wheel that increases the stability of the sliding door, including support, the rotatable connection of the wheel is arranged between the inner wall of both sides of the support, the fixed connection of the main shaft is arranged at the center of the top surface of the support, the stable mechanism is arranged on the support, the cutting assembly is arranged on the inner wall of both sides of the support;

[0007] The stable mechanism includes two symmetrically distributed support plates and two movable grooves, both of the support plates are fixedly connected to the top surface of the support, the outer wall of one side of the support plate is fixedly connected with the guide rod, the outer wall of the side away from the support plate of the guide rod is coaxially fixedly connected with the limiting plate, the outer surface of the guide rod is slidably sleeved with the Z-shaped plate, the outer surface of the guide rod is sleeved with the spring one, both of the movable grooves are throughly arranged on the top surface of the support and correspond to the two Z-shaped plates, the bottom of both of the Z-shaped plates passes through the corresponding movable groove and the outer wall of one side is fixedly connected with the fixed seat, the outer wall of the side away from the corresponding Z-shaped plate of the fixed seat is rotatably connected with the auxiliary wheel.

[0008] It should be noted in the solution that each set of cutting components includes a fixing plate, which is fixedly connected to the inner wall of one side of the support. A sliding rod is provided on the top surface of the fixing plate, a spring is sleeved on the outer surface of the sliding rod, a fixing block is fastened to the outer surface of the sliding rod, a force-bearing block is coaxially fixedly connected to the top of the sliding rod, and a cutting blade is fixedly connected to the bottom end of the sliding rod through the bottom surface of the fixing plate.

[0009] It is worth noting that two symmetrically distributed pressure seats that cooperate with the force-bearing block are fixedly connected to the outer walls on both sides of the wheel, and three evenly distributed extrusion shafts are rotatably embedded on the bottom surface of the pressure seats.

[0010] Furthermore, it should be noted that a spring is installed on the outer surface of the spindle, and a mounting component is provided on the outer surface of the spindle.

[0011] In a preferred embodiment, each Z-shaped plate is slidably engaged with a corresponding movable groove, and the outer walls on both sides of each spring are respectively fixedly connected to one side of the outer wall of the corresponding support plate and one side of the outer wall of the corresponding Z-shaped plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By pinching the two Z-shaped plates to make them fit against the outer walls of the wheels on both sides, after placing the wheels inside the track, release the two Z-shaped plates. Under the action of spring one, push the Z-shaped plates to move inside the movable groove. The Z-shaped plates drive the auxiliary wheel to contact the inner wall of the track, which plays a supporting and assisting role in sliding, improving the stability of the sliding door and effectively avoiding the problem of instability of the sliding door caused by insufficient contact between the corner wheel and the inner wall of the track.

[0015] 2. The rotation of the wheel drives the pressure seat to squeeze the force block, which in turn pushes the cutter through the slide rod to cut the filamentous material. The spring 2 resets the cutter. The two symmetrically distributed pressure seats repeatedly squeeze the force block, preventing the filamentous material from getting tangled in the wheel, thus improving the smoothness of the wheel's rotation. This effectively avoids the problem of filamentous material easily getting tangled on the outer surface of the corner wheel during long-term use, which can cause it to rotate unevenly.
