[0026] A height adjustment device 20 for a pull rod placement rack 10, wherein the placement rack 10 includes: a placement plate 11 and a top plate 12, wherein the placement plates 11 are arranged at equal intervals along the height direction, and the placement plates 11 can slide along the height direction; the top plate 12 is installed on the placement plate 11 at the top, such as Figure 1 As shown; wherein the adjustment device 20 is used to adjust the distance between the placement plates 11 and the distance between the top plate 12 and the placement plate 11;

[0027] Furthermore, the regulating device 20 mentioned above includes:

[0028] The sliding blocks 21 are slidably mounted on two opposite sides of the placement plate 11 and the top plate 12, and two sliding blocks 21 are installed. The sliding blocks 21 can move forward and backward along the side. As a preference, the sliding blocks 21 are mounted on the side in the width direction, which is convenient for users to place items in the length direction of the placement rack 10;

[0029] Scissor rods 22, two scissor rods 22 are hinged in the middle to form a scissor assembly, and several scissor assemblies are arranged along the height direction of the placement rack 10, and each scissor assembly is connected end to end, and both ends of the scissor rods 22 are rotatably connected to the sliding blocks 21. As the two sliding blocks 21 at the ends of the scissor rods 22 move away from or close to each other, the height direction of the ends of the scissor rods 22 will change, thereby making the distance between each placement rack 10 synchronously change to adjust the height of the placement rack 10 to accommodate different specifications of pull rods placed on the placement rack 10;

[0030] The driving member 23 is installed on the side of one of the placement plates 11. The driving member 23 is used to make the two sliding blocks 21 in corresponding positions move closer to or farther away from each other, so as to control the scissors assembly and adjust it according to actual conditions. Specifically, the driving member 23 includes: a screw rod 232, which is threadedly engaged with the sliding block 21; a motor 231, which is installed on the side of one of the placement plates 11, and is used to drive the screw rod 232 to rotate so that the sliding blocks 21 move away from or closer to each other. Preferably, the motor 231 should be installed on the placement plate 11 near the middle of the placement frame 10 to achieve the purpose of uniform force on the screw rod 232, and the motor 231 is located between the two sliding blocks 21; the screw rod 232 is installed on both sides of the motor 231, and the two screw rods 232 are coaxially arranged, and the thread rotation directions of the two screw rods 232 are opposite to each other.

[0031] Based on the further improvement of the above structure, the adjustment device 20 further includes:

[0032] The cylinder 24 is installed at the four corners of the placement plate 11. The stationary end of the cylinder 24 is installed on the surface of the placement plate 11, and the telescopic end of the cylinder 24 is installed on the bottom of the placement plate 11. The telescopic end of the cylinder 24 is also installed on the bottom of the top plate 12. Figure 1 and 2 As shown; further, an air duct 111 connected to the cylinder 24 is opened in the placement plate 11; based on the above structure, the adjustment device 20 further includes a piston rod 25, one end of the piston rod 25 is fixed to the sliding block 21, and the other end is slidably embedded in the air duct 111.

[0033] Specifically, when the two sliding blocks 21 approach each other, the sliding blocks 21 drive the piston rod 25 to approach each other, and the piston at the end of the piston rod 25 pushes the gas in the airway 111 to move toward the cylinder 24. At this time, the cylinder 24 pushes upward to further assist in increasing the height between each layer of the placement rack 10; when the two sliding blocks 21 move away from each other, the sliding blocks 21 drive the piston rod 25 to move away from each other, so that a negative pressure is formed in the airway 111, so that the gas in the cylinder 24 enters the airway 111, causing the cylinder 24 to contract downward, so as to further assist in reducing the height between each layer of the placement rack 10.

[0034] Based on the further improvement of the above structure, a sliding groove 13 that fits with the sliding block 21 is opened on the side of the placement plate 11 or the top plate 12, and a guide rod 131 is fixed in the sliding groove 13. The sliding block 21 is movably connected to the guide rod 131 to guide the travel of the sliding block 21 to prevent the sliding block 21 from detaching and causing a malfunction.

[0035] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0036] Those skilled in the art will appreciate that the above embodiments are merely for the purpose of illustrating the present invention and are not intended to limit the scope of the present invention. Other variations or modifications may be made based on the above disclosure, and such variations or modifications are still within the scope of the present invention.
