DETAILED DESCRIPTION

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0038] like Figure 1 and 2 As shown, the present invention mainly includes a fixing column 1, a side baffle 2, a rear baffle 3, a pressing plate, a spring 8 and a pressing column 9.

[0039] like Figure 1 and 3 As shown, a plurality of pressing disks arranged side by side are sleeved on the fixed column 1, and the pressing disks include an outer pressure ring 4, an inner pressure ring 5, a ball retainer 6 and balls 7. An inner pressure ring 5 is provided on the inner ring of the outer pressure ring 4, and a ball retainer 6 is provided between the outer pressure ring 4 and the inner pressure ring 5. A plurality of freely rolling balls 7 are provided in the circumferential direction of the ball retainer 6, and the balls 7 are rollingly connected to the inner ring surface of the outer pressure ring 4 and the outer ring surface of the inner pressure ring 5 respectively.

[0040] like Figure 2As shown, the inner ring of the pressing plate is provided with a sliding cavity 13 capable of accommodating the sliding of the fixing column 1 forward and backward, and the pressing plate adjusts its relative position with the fixing column 1 through the sliding cavity 13. Figure 3 As shown, a plurality of mounting holes 14 are provided on the end surface of the fixing column 1 facing the pressing disk, and the plurality of mounting holes 14 are arranged one by one corresponding to the plurality of pressing disks. The mounting holes 14 pass through the fixing column 1 from front to back. The plurality of mounting holes 14 are distributed in two rows along the length direction of the fixing column 1, and two adjacent mounting holes 14 are staggered in different rows.

[0041] like Figure 3 As shown, a pressing column 9 is provided between each pressing disk and the fixing column 1, one end of the pressing column 9 contacts the inner ring end face of the pressing disk, and the other end is slidably connected in a mounting hole 14. A radially protruding stopper 11 is provided in the middle of the pressing column 9, and a stopper 15 is provided in the mounting hole 14. A spring 8 is sleeved on one end of the pressing column 9 facing the fixing column 1, and the two ends of the spring 8 contact the stopper 11 and the stopper 15 respectively. The spring force of the spring 8 can make the front end of the pressing column 9 press against the inner ring end face of the pressing disk.

[0042] like Figure 3 As shown, in order to allow the spring 8 to be compressed to a longer stroke, a pressure column hole 16 is provided at the center of the limiting member 15 , and the end of the pressure column 9 facing the fixed column 1 can slide back and forth along the pressure column hole 16 .

[0043] like Figure 3 As shown, in order to prevent the end of the spring 8 from twisting when compressed, a circle of positioning rings 17 are provided along the circumferential direction on the outer edge of the limit platform 11, and the spring 8 is located in the inner circle of the positioning ring 17. When the spring 8 is about to be twisted under pressure, the positioning ring 17 can prevent the end of the spring 8 from twisting.

[0044] like Figure 3 As shown, in order to prevent the end of the spring 8 from twisting when compressed, the stopper 15 is provided with a circle of positioning grooves 18 along the circumferential direction facing one end of the spring 8, and the positioning grooves 18 can accommodate the end of the spring 8. When the spring 8 is compressed and is about to be twisted, the positioning grooves 18 can prevent the end of the spring 8 from twisting.

[0045] like Figure 3 As shown, in order to make the contact between the pressure column 9 and the pressing disk more stable, a positioning hole 19 is provided on the inner ring end surface of the pressing disk, and the end of the pressure column 9 extends into the positioning hole 19 to contact the pressing disk.

[0046] When in use, the pressure of the spring 8 is transmitted to the pressing disc through the pressing column 9. Due to the small area of ​​the end of the pressing column 9, the pressure of the spring 8 cannot be evenly applied to the outer ring end surface of the pressing disc. In order to make the pressure of the spring 8 act as evenly as possible on the outer ring end surface of the pressing disc, Figure 4As shown, a pressure plate 21 is transversely provided on one end of the pressure column 9 facing the pressing disk, and a positioning groove 20 capable of accommodating the pressure plate 21 is transversely provided on the inner ring end surface of the pressing disk. The pressure plate 21 extends into the positioning groove 20 and contacts the bottom end surface of the positioning groove 20.

[0047] When in use, the pressure of the spring forces the pressing disc to extend and press against the tire tread. The thickness of different positions on the tread of some tires is different, resulting in different pressures at different thickness positions. In order to ensure that the tire tread at different thickness positions is evenly stressed, it is necessary to adjust the extension amount of each pressing column 9 to drive the pressing disc.

[0048] In order to achieve the above purpose, Figure 5 As shown, the limit member 15 is connected to the mounting hole 14 by means of threads, and an adjusting transverse groove 22 is provided at one end of the limit member 15 facing away from the pressure column 9. When it is necessary to adjust the position of the limit member in the mounting hole 14, a screwdriver is inserted into the adjusting transverse groove 22 to screw the limit member 15, so as to adjust the front and rear positions of the limit member 15 in the mounting hole 14, thereby finally realizing the adjustment of the front and rear pressing positions of the pressing disk.

[0049] like Figure 1 As shown, baffle assemblies are respectively provided at both ends of the fixed column 1. The baffle assemblies at both ends of the fixed column 1 are respectively located at both ends of the pressing structure composed of multiple pressing disks. The baffle assemblies are used to limit the pressing disks from escaping from both ends of the fixed column 1.

[0050] like Figure 1 As shown, the baffle assembly includes two side baffles 2 which are symmetrically arranged with the fixed column 1 as the center. The side baffles 2 are detachably connected to the fixed column 1 through connecting pieces. The side baffles 2 can prevent the pressing disk from escaping from both ends of the fixed column 1.

[0051] like Figure 1 As shown, a rear baffle 3 is provided along the length direction at one end of the fixed column 1 facing away from the pressing column 9, and the rear baffle 3 is located in a sliding cavity 13 between the fixed column 1 and the pressing disk. The rear baffle 3 is detachably connected to the surface of the fixed column 1 through a connecting piece, and the end of the rear baffle 3 facing the pressing disk is in contact with the inner ring surface of the pressing disk, and the end of the rear baffle 3 facing the fixed column 1 covers a plurality of mounting holes 14 on the fixed column 1.

[0052] The working principle of the present invention is: when the tire tread is pressed, the tire tread extends under the pressing end faces of multiple pressing discs, and the tire tread causes the pressing disc to contract toward the fixed column. After the spring is compressed, the pressing column provides pressure to the pressing disc, and finally the pressing disc is pressed against the tire tread. During use, the thickness of some tire treads at different positions is different, resulting in different pressures at positions of different thicknesses. In order to ensure that the tire tread at positions of different thicknesses is uniformly stressed, it is necessary to adjust the extension amount of the pressing disc driven by each pressing column. When it is necessary to adjust the position of the limiter in the mounting hole, extend a screwdriver into the adjusting transverse groove to screw the limiter, and adjust the front and rear positions of the limiter in the mounting hole, and finally adjust the front and rear pressing positions of the pressing disc, and ensure that the tire tread at positions of different thicknesses is uniformly stressed.

[0053] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
