[0021] The lifting and lowering wheels according to the embodiments of this utility model have at least the following technical effects:

[0022] 1. The lifting wheel is installed on the furniture. When the roller is needed, the force of the spring is overcome to rotate the pedal, which drives the rotating seat to rotate. At this time, the spring is stretched, and the rotating seat drives the roller to rotate and descend, so that the second contact surface abuts against the upper end surface of the rotating seat. At this time, the lowest end of the roller is lower than the lowest end of the support seat, and the roller contacts the ground.

[0040] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0041] According to some embodiments of this utility model, refer to Figures 1 to 4The lifting wheel assembly includes a bracket 100, a rotating seat 200, a support seat 300, a spring member 500, and a pedal 400. The rotating seat 200 is rotatably connected to the bracket 100, and a roller 210 is rotatably connected to the lower end of the rotating seat 200. The support seat 300 is mounted on the bracket 100. The upper end of the spring member 500 is connected to the bracket 100, and the lower end of the spring member 500 is connected to the rotating seat 200. The pedal 400 is rotatably connected to the bracket 100 and has a first abutment surface 410 and a second abutment surface 420. Rotation of the pedal 400 can drive the rotating seat 200 to rotate, and when the first abutment surface 410 abuts against the upper surface of the rotating seat 200, the lowermost end of the roller 210 is higher than the lowermost end of the support seat 300. When the pedal 400 rotates clockwise, it overcomes the force of the spring 500 to drive the rotating seat 200 to rotate. When the second abutment surface 420 abuts against the upper end surface of the rotating seat 200, the lowest point of the roller 210 is lower than the lowest point of the support 300. The pedal 400, bracket 100, and rotating seat 200 are relatively fixed and self-locking. The spring 500 applies a rotational upward biasing force to the rotating seat 200. This allows the lifting wheels to be installed on furniture.

[0042] Reference Figure 3 and Figure 4 When roller 210 is needed, the pedal 400 is rotated clockwise, which causes the rotating seat 200 to rotate clockwise. At this time, the force overcoming the spring 500 stretches the spring 500, causing the rotating seat 200 to rotate and descend, and roller 210... Figure 3 The state rotates down to Figure 4 In this state, the second abutment surface 420 of the pedal 400 abuts against the upper end surface of the rotating seat 200. The lowest end of the roller 210 is lower than the lowest end of the support base 300. The roller 210 is in contact with the ground. The pedal 400, bracket 100, and rotating seat 200 are relatively fixed to achieve self-locking. The spring 500 applies a rotational upward bias force to the rotating seat 200, thereby enabling the lifting wheel to rotate through the roller 210, thus moving the furniture. It can be understood that when the roller 210 is in contact with the ground, the roller 210 receives an upward force from the ground, causing the upper end surface of the rotating seat 200 to tightly adhere to the second abutment surface 420 and apply an upward force to the second abutment surface 420, making it difficult for the pedal 400 to rotate relative to the rotating seat 200, thus achieving self-locking.

[0043] Reference Figure 3 and Figure 4 When roller 210 is not needed, rotating pedal 400 counterclockwise causes the second contact surface 420 to gradually disengage from the upper surface of rotating seat 200. Simultaneously, under the action of spring 500, rotating seat 200 rotates counterclockwise, causing roller 210 to rotate and rise. Figure 4The state rotates and rises to Figure 3 In this state, the first contact surface 410 of the pedal 400 abuts against the upper surface of the rotating seat 200, the lowermost end of the roller 210 is higher than the lowermost end of the support seat 300, and the support seat 300 is in contact with the ground. It can be understood that, because the first contact surface 410 and the second contact surface 420 have a certain angle, without external force interference, the pedal 400 is difficult to rotate relative to the rotating seat 200 to change the upper surface of the rotating seat 200 from abutting against the first contact surface 410 to abutting against the second contact surface 420, thus completing the self-locking mechanism.

[0044] According to some embodiments of this utility model, refer to Figures 1 to 4 The bracket 100 is provided with a first shaft 110 and a second shaft 120. The first shaft 110 and the second shaft 120 are arranged in parallel. The axial directions of the first shaft 110 and the second shaft 120 are both in the left and right direction. The first shaft 110 is lower than the second shaft 120. The first shaft 110 passes through and is rotatably connected to the rotating seat 200, and the second shaft 120 passes through and is rotatably connected to the pedal 400.

[0045] Preferred, refer to Figure 4 The rear side of the first abutting surface 410 is connected to the front side of the second abutting surface 420. The included angle between the first abutting surface 410 and the second abutting surface 420 is θ, which is an obtuse angle. The connection between the first abutting surface 410 and the second abutting surface 420 adopts a rounded corner design to facilitate a smooth transition between the upper end surface of the rotating seat 200 and the first abutting surface 410 and the second abutting surface 420. The distance between the first abutment surface 410 and the second shaft 120 is smaller than the distance between the second abutment surface 420 and the second shaft 120. Since the distance between the second abutment surface 420 and the second shaft 120 is larger than the distance between the first abutment surface 410 and the second shaft 120, when the second abutment surface 420 is in contact with the upper end surface of the rotating seat 200, the distance between the upper end surface of the rotating seat 200 and the second shaft 120 is larger. This means that when the second abutment surface 420 is in contact with the upper end surface of the rotating seat 200, the roller 210 is located lower than when the first abutment surface 410 is in contact with the upper end surface of the rotating seat 200.

[0046] This technical solution utilizes the principles of eccentricity and small-angle self-locking to achieve the raising and lowering of the roller 210. This lifting and lowering roller has a simple structure, is easy to operate, and has a long service life.

[0047] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The rotating seat 200 is provided with a third shaft 220, which is lower than the first shaft 110. The third shaft 220 passes through and is rotatably connected to the roller 210, so that the roller 210 is rotatably connected to the rotating seat 200.

[0048] According to some embodiments of this utility model, refer to Figure 2 The upper end face of the bracket 100 is provided with a first through hole 130, and the wall of the first through hole 130 is provided with a first protrusion 131. The first protrusion 131 is inclined upward, and the upper end of the spring member 500 is hung on the first protrusion 131, so that the upper end of the spring member 500 is connected to the bracket 100, and the assembly between the spring member 500 and the first protrusion 131 is simple and easy to disassemble.

[0049] According to some embodiments of this utility model, refer to Figure 2 The upper end face of the rotating seat 200 is provided with a second through hole 230, and the hole wall of the second through hole 230 is provided with a second protrusion 231. The second protrusion 231 is inclined downward, and the lower end of the spring member 500 is hung on the second protrusion 231, so that the lower end of the spring member 500 is connected to the rotating seat 200, and the assembly between the spring member 500 and the second protrusion 231 is simple and easy to disassemble.

[0050] According to some embodiments of this utility model, refer to Figure 2 The upper surface of the pedal 400 is provided with multiple anti-slip protrusions 430, which are spaced apart in the front-to-back direction. The anti-slip protrusions 430 can play an anti-slip role, ensuring that the operator can apply force to the pedal 400 without slipping.

[0051] According to some embodiments of this utility model, refer to Figure 2 The pedal 400 is provided with a third through hole 440, and the lifting wheel also includes a handle ring 450, which passes through the third through hole 440. The operator can apply force to the pedal 400 through the handle ring 450, and the lifting wheel can also be hung and stored through the handle ring 450.

[0052] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The upper end of the bracket 100 is rotatably connected to the mounting base 510. The mounting base 510 is provided with multiple fourth through holes 520. The multiple fourth through holes 520 are distributed around the circumference of the mounting base 510. The fourth through holes 520 are used to connect with bolts, and the bolts are then connected to the bottom of the furniture, so that the mounting base 510 is installed on the bottom of the furniture.

[0053] According to some embodiments of this utility model, refer to Figures 1 to 4The support base 300 includes a fixed base 310 and a support foot 320.
