Description

Technical Field

[0001] The utility model relates to a slope footrest for the rear row with adjustable angle, specifically a slope footrest for the rear row with adjustable angle, belonging to the technical field of footrests. Background Technique

[0002] Generally, the seat surface of a throne or a large chair is relatively high, exceeding the height of a person's calf. When sitting on the chair, the feet will surely hang in the air. If a footstool is set and the legs and feet are placed on the footstool, a comfortable purpose can be achieved.

[0003] The footrests of the prior art have the following disadvantages: 1. The pedals with fixed angles do not meet the needs of people with different heights, and the comfort level of use is low; 2. During the continuous use of the pedals, they are in continuous contact with people's shoes, and the wear resistance is poor and easy to wear. Therefore, improvements are made for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a slope footrest for the rear row with adjustable angle to solve the above problems. The hydraulic cylinder and the motor cooperate to adjust the height and inclination angle of the pedal; the reinforcing plate, the wear-resistant cloth and the wear-resistant layer cooperate to improve the wear resistance of the pedal.

[0005] The utility model realizes the above purpose through the following technical solutions. A slope footrest for the rear row with adjustable angle includes a base. A positioning frame is installed inside the base. The positioning frame is rotatably connected with a rotating plate b. The rotating plate b is rotatably connected with a support plate through a sliding rod. The support plate is fixedly connected with a cross plate. The cross plate is rotatably connected with a rotating plate a. The rotating plate a is rotatably connected with a moving frame. A hydraulic cylinder is installed on the moving frame. The cross plate is rotatably connected with a pedal. The pedal is rotatably connected with a screw rod. The screw rod is threadedly connected with a clamping frame. The clamping frame is inserted into a limiting frame. The pedal includes a base plate, a reinforcing plate, a wear-resistant cloth and a wear-resistant layer, and the base plate is compounded with the reinforcing plate.

[0006] Preferably, a motor is installed below the pedal. The output end of the motor is fixedly connected with a rotating shaft, and a bevel gear a is installed on the rotating shaft.

[0007] Preferably, the bevel gear a is meshed and connected with a bevel gear b, and the bevel gear b is installed on the screw rod.

[0008] Preferably, the cross plate is fixedly connected with a limiting frame, and a clamping hole is formed in the limiting frame, and the clamping frame is inserted into the clamping hole.

[0009] Preferably, the hydraulic cylinder is installed with a positioning frame, and the moving frame is slidably connected with the base.

[0010] Preferably, the sliding rod is slidably connected with the support plate, the reinforcing plate is adhered with the wear-resistant cloth, and the wear-resistant layer is coated on the surface of the wear-resistant cloth.

[0011] The beneficial effects of the present utility model are as follows:

[0012] The hydraulic cylinder and the motor cooperate to adjust the height and tilt angle of the pedal. When adjusting the height of the pedal, the hydraulic cylinder in the base shortens. One end of the hydraulic cylinder is connected to the positioning frame, and the other end is connected to the moving frame. The positioning frame is rotatably connected to the rotating plate b, and the other end of the rotating plate b is rotatably connected to the support plate through a sliding rod. The moving frame is rotatably connected to the rotating plate a, and the other end of the rotating plate a is rotatably connected to the cross plate. The continuous shortening of the hydraulic cylinder drives the moving frame to move leftward. While the moving frame moves leftward, it drives the rotating plate a to rotate. At the same time, the sliding rod on the rotating plate a slides leftward along the support plate, and at the same time pushes the cross plate upward, that is, drives the pedal on the cross plate to move upward, and the overall height increases. When adjusting the rotation angle of the pedal, the motor on the pedal rotates to drive the bevel gear a connected to the rotating shaft to rotate. The rotation of the bevel gear a drives the meshing bevel gear b to rotate. The rotation of the bevel gear b drives the connected screw rod to rotate. Opposite threads are provided on both sides of the screw rod. The continuous rotation of the screw rod drives the two side clamping frames to move inward. The continuous inward movement of the clamping frames separates from the clamping holes on the limiting frame. After separation, the pedal is lifted upward to rotate upward, or pressed downward to rotate downward. After the pedal angle is adjusted, the motor rotates in reverse. The reverse rotation of the motor drives the bevel gear a to rotate in the opposite direction. The rotation of the bevel gear a drives the bevel gear b to rotate. The rotation of the screw rod drives the clamping frames to move outward. The outward movement of the clamping frames inserts into the clamping holes to fix the position of the pedal. The pedal can be adjusted through the cooperation of the hydraulic cylinder and the motor.

[0013] The reinforcing plate, wear-resistant cloth and wear-resistant layer cooperate to improve the wear resistance of the pedal. The pedal is composed of a base plate, a reinforcing plate, a wear-resistant cloth and a wear-resistant layer. The material of the reinforcing plate is polyether ether ketone, which has high mechanical strength, good toughness and rigidity, excellent sliding characteristics and good wear resistance. The material of the wear-resistant cloth is nylon, which has good wear resistance. The material of the wear-resistant layer on the outer layer of the wear-resistant cloth is fluororesin, which has a low friction coefficient and small wear after contacting the outside world. It can cooperate with the wear-resistant cloth and the reinforcing plate to improve the overall wear resistance of the pedal. Description of the Drawings

Opposite threads are provided on both sides of the screw 14. The rotation of the screw 14 can drive the card frames 4 to approach or move away from each other. The card frame 4 is inserted into a limit frame 2. The pedal 1 includes a substrate plate 21, a reinforcing plate 20, a wear-resistant cloth 19, and a wear-resistant layer 18. The pedal 1 is composed of a combination of a substrate plate 21, a reinforcing plate 20, a wear-resistant cloth 19, and a wear-resistant layer 18. The substrate plate 21 is compounded with the reinforcing plate 20.

[0021] Specifically, the bevel gear a 13 is meshed and connected with a bevel gear b 15. The rotation of the bevel gear a 13 drives the connected bevel gear b 15 to rotate. The bevel gear b 15 is installed with a screw 14. The rotation of the bevel gear b 15 drives the connected screw 14 to rotate.

[0022] Specifically, the horizontal plate 5 is fixedly connected to a limit frame 2. The horizontal plate 5 can fix the position of the limit frame 2. The limit frame 2 is provided with a card hole 3. The card frame 4 is inserted into the card hole 3.

The output end of the motor 10 is fixedly connected to a rotating shaft, and the rotation of the motor 10 drives the rotation of a bevel gear a13 connected to the rotating shaft. The rotating shaft is installed with the bevel gear a13.

[0026] When the present utility model is in use, when adjusting the height of the pedal 1, the hydraulic cylinder 8 in the base 6 shortens.

After separation, the pedal 1 is lifted upward to rotate it upward, or pressed downward to rotate the pedal 1 downward. After the angle of the pedal 1 is adjusted, the motor 10 rotates in reverse. The reverse rotation of the motor 10 drives the bevel gear a13 to rotate in the reverse direction. The rotation of the bevel gear a13 drives the bevel gear b15 to rotate. The rotation of the screw 14 drives the clamping frames 4 to move outward. The outward movement of the clamping frames 4 inserts into the clamping holes 3 to fix the position of the pedal 1. The pedal 1 can be adjusted by the cooperation of the hydraulic cylinder 8 and the motor 10. The pedal 1 is composed of a base plate 21, a reinforcing plate 20, a wear-resistant cloth 19 and a wear-resistant layer 18.
