[0023] like Figure 1-Figure 3 As shown, the utility model provides the following technical solutions: a control ring operation structure, including a barrel body 1, the barrel body 1 is a structure with openings at both ends and a closed middle, rubber blocks 2 are slidably arranged in the two ends of the barrel body 1, and the side walls of the rubber blocks 2 are detachably connected with a reset mechanism, which is fixedly arranged in the barrel body 1. The reset mechanism can push the rubber block 2 to move and always fit the surface of the steel ball, and a positioning mechanism is fixedly connected in the barrel body 1, and the positioning mechanism can limit the sliding rubber block 2 in one direction.

[0024] Please combine Figure 1 As shown, during use, the barrel body 1 with the rubber block 2 is placed between the two steel balls, and then the staff operates the positioning mechanism to cancel the limit on the rubber block 2, and then pushes the rubber block 2 into the barrel body 1, and then fits it with the steel ball, and then the control ring is put into use. The long-term rotation of the steel ball causes wear on the contact surface of the rubber block 2. When the rubber block 2 is worn and a gap occurs between the steel ball, the reset mechanism pushes the rubber block 2 to move and contact the surface of the steel ball again. The movement of the rubber block 2 pushes the positioning mechanism to move, and the positioning mechanism limits the rubber block 2 to prevent the steel ball from pushing the rubber block 2 into the barrel body 1, effectively preventing the steel ball from shaking.

[0025] The surface where the rubber block 2 and the steel ball are in contact is a curved surface.

[0026] Please combine Figure 1 As shown, during use, the surface of the rubber block 2 that fits the steel ball is an arc surface, which increases the contact area with the surface of the steel ball, thereby improving the stability of the steel ball during rotation.

[0027] The cross section of the side wall where the rubber block 2 contacts the barrel body 1 is a corrugated surface.

[0028] Please combine Figure 1 As shown, during use, the side wall section where the rubber block 2 contacts the barrel body 1 is a corrugated surface, which reduces the contact area between the rubber block 2 and the barrel body 1 and facilitates the sliding of the rubber block 2.

[0029] The reset mechanism includes a threaded barrel 3 screwed to the side wall of the rubber block 2, the threaded barrel 3 is arranged in the barrel body 1, a multi-section telescopic rod 4 is fixedly connected between the threaded barrel 3 and the barrel body 1, a compression spring 5 is fitted between the threaded barrel 3 and the barrel body 1, and the compression spring 5 is sleeved on the multi-section telescopic rod 4.

[0030] Please combine Figure 1 As shown, during use, when the steel ball rotates and causes the rubber block 2 to wear, the compression spring 5 pushes the threaded barrel 3 to move, and the threaded barrel 3 drives the rubber block 2 to move and fit with the surface of the steel ball again to prevent the steel ball from shaking during rotation. When the multi-section telescopic rod 4 is extended to the longest, the rubber block 2 just slides out of the barrel body 1.

[0031] The positioning mechanism includes a plurality of grooves 6 and a positioning groove 10. The plurality of positioning grooves 10 are arranged on the bottom surface of the rubber block 2 along the direction close to the port of the barrel body 1. The cross section of the positioning groove 10 is square. The groove 6 is arranged on the inner bottom surface of the barrel body 1. The plurality of grooves 6 are connected by a slide groove 8. The slide groove 8 is arranged on the bottom surface of the barrel body 1. A connecting rod 7 is provided for sliding in the slide groove 8. The top end of the connecting rod 7 penetrates into the groove 6 and is fixedly connected with a positioning block 9. The cross section of the positioning block 9 is a right triangle. The positioning block 9 is arranged in the positioning groove 10. The positioning block 9 is arranged in the positioning groove 10 and fits with the surface of the rubber block 2. The inclined surface of the positioning block 9 is arranged to be inclined downward along the direction close to the connecting rod 7. The inclined surfaces of the two positioning blocks 9 are arranged to face each other. A reset spring 11 is fixedly connected between the positioning block 9 and the barrel body 1. The reset spring 11 is sleeved on the vertical rod of the connecting rod 7. The elastic force of the reset spring 11 is less than the elastic force of the compression spring 5.

[0032] Please combine Figure 1As shown, during use, when the rubber block 2 wears and slides, the compression spring 5 will indirectly push the rubber block 2 to move, and the rubber block 2 drives the positioning groove 10 to move. The rubber block 2 pushes the positioning block 9 to move the pressurized return spring 11 to deform, and the positioning block 9 drives the connecting rod 7 to move. The shape and position setting of the positioning block 9 realizes one-way limiting of the rubber block 2 to prevent the rubber block 2 from sliding into the barrel body 1.

[0033] A latch 13 is slidably provided through the top surface of the barrel body 1, and a limiting hole 12 is provided on the top surface of the threaded barrel 3. The bottom end of the latch 13 penetrates into the limiting hole 12 and is slidably connected thereto.

[0034] Please combine Figure 1 As shown, during use, when the barrel body 1 with the rubber block 2 is installed between the two steel balls, there is no need for the staff to operate the positioning mechanism to cancel the limit on the rubber block 2 and push the rubber block 2 into the barrel body 1, and then fit it with the steel ball. The rubber block 2 is directly fitted with the surface of the steel ball, and then the corresponding pin 13 is pulled out. The pin 13 cancels the limit on the threaded barrel 3, so that the compression spring 5 can have a tendency to push the threaded barrel 3 to drive the rubber block 2 to move.

[0035] The limiting hole 12 is trumpet-shaped and opens upward.

[0036] Please combine Figure 1 As shown, during use, the limiting hole 12 is trumpet-shaped and the opening is facing upward, and the latch 13 is inserted into the limiting hole 12 to limit the threaded barrel 3.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
