One end of the annular rubber sealing band 100 is provided with the first protrusion 201 and the second groove 204. The other end of the annular rubber sealing band 100 is provided with the second protrusion 202 matched with the second groove 204 and the first groove 203 matched with the first protrusion 201. The annular rubber sealing band 100 is attached to the shaft part, so that the second protrusion 202 is clamped in the second groove 204, and the first protrusion 201 is clamped in the first groove 203. The two ends of the annular rubber sealing band 100 can be spliced to form a closed rubber ring.

[0034] In a preferred embodiment, please refer to Figures 1 to 4 The fixed assembly 300 is composed of a knob 301, a connecting rod 302, a threaded rod 303, a first threaded sleeve 304, a second threaded sleeve 305, a mounting hole 306 and a mounting groove 307. The annular rubber sealing band 100 is provided with the knob 301 outside. The connecting rod 302 is fixedly arranged on the side of the knob 301. The threaded rod 303 is fixedly arranged on the other side of the connecting rod 302. The first threaded sleeve 304 and the second threaded sleeve 305 are threadedly connected to the outer side of the threaded rod 303. The inner threads matched with the threaded rod 303 are arranged on the inner sides of the first threaded sleeve 304 and the second threaded sleeve 305. The mounting hole 306 matched with the first threaded sleeve 304 is arranged on the side of the first protrusion 201. The first threaded sleeve 304 penetrates the first protrusion 201 through the mounting hole 306 and is fixedly connected with the inner wall of the mounting hole 306. The mounting groove 307 matched with the second threaded sleeve 305 is arranged on the side of the second protrusion 202. The second threaded sleeve 305 is inserted into the mounting groove 307 and is fixedly connected with the inner wall of the mounting groove 307.

[0035] In the embodiment, when the annular rubber sealing band 100 is spliced, the mounting hole 306 is communicated with the mounting groove 307, and the inner thread of the first threaded sleeve 304 is just aligned with the inner thread of the second threaded sleeve 305. The knob 301 is rotated to drive the connecting rod 302 and the threaded rod 303 to rotate, so that the threaded rod 303 is threadedly connected with the first threaded sleeve 304 and the second threaded sleeve 305 in sequence, and the two ends of the annular rubber sealing band 100 can be fixed, so that the installation of the annular rubber sealing band 100 is completed. The knob 301 is reversely rotated to drive the threaded rod 303 to be separated from the first threaded sleeve 304 and the second threaded sleeve 305, the first protrusion 201 is pried up and pulled outward, and the annular rubber sealing band 100 can be disassembled, so that the operation difficulty is low.

[0036] In a preferred embodiment, referring to Figures 1 to 4 The outer part of the annular rubber sealing band 100 is provided with a rubber pad 400, and the outer side of the connecting rod 302 is provided with a pressing plate 401 penetratingly arranged, the pressing plate 401 is movably connected with the connecting rod 302, and the outer surface of the pressing plate 401 is pasted with the rubber pad 400.

[0037] In the embodiment, the rubber pad 400 is arranged between the knob 301 and the threaded rod 303, the outer diameter length of the connecting rod 302 is less than the outer diameter length of the knob 301 and the threaded rod 303, when the knob 301 is rotated to drive the connecting rod 302 and the threaded rod 303 to rotate, the threaded rod 303 is threadedly connected with the first threaded sleeve 304 and the second threaded sleeve 305, so that the knob 301 and the connecting rod 302 can be close to or away from the annular rubber sealing band 100, so as to drive the rubber pad 400 and the pressing plate 401 to be close to or away from the annular rubber sealing band 100. When the fixing assembly 300 fixes the two ends of the annular rubber sealing band 100, the extrusion of the knob 301 on the rubber pad 400 in cooperation with the annular rubber sealing band 100 makes the rubber pad 400 close to and tightly adhere to the annular rubber sealing band 100, at this time, the rubber pad 400 covers the splicing position on the outer side of the annular rubber sealing band 100, so that the sealing effect of the annular rubber sealing band 100 can be improved, and the gas, lubricating oil or other liquid outside can be prevented from leaking inward through the splicing position on the outer side of the annular rubber sealing band 100.

[0038] The working principle of the utility model is as follows:

[0039] When the device is used, the annular rubber sealing band 100 is attached to the inner part of the shaft, the second protrusion 202 is clamped in the second groove 204, and the first protrusion 201 is clamped in the first groove 203. The two ends of the annular rubber sealing band 100 can be spliced to form a closed rubber ring. When the annular rubber sealing band 100 is spliced, the mounting hole 306 is in communication with the mounting groove 307, and the internal thread of the first threaded sleeve 304 is aligned with the internal thread of the second threaded sleeve 305. Rotating the knob 301 drives the connecting rod 302 and the threaded rod 303 to rotate, so that the threaded rod 303 is threadedly connected with the first threaded sleeve 304 and the second threaded sleeve 305 in turn. The two ends of the annular rubber sealing band 100 can be fixed, so that the installation of the annular rubber sealing band 100 is completed. Rotating the knob 301 drives the connecting rod 302 and the threaded rod 303 to rotate, which can simultaneously drive the rubber pad 400 and the pressing plate 401 to approach the annular rubber sealing band 100. When the fixing assembly 300 fixes the two ends of the annular rubber sealing band 100, the knob 301 cooperates with the annular rubber sealing band 100 to extrude the rubber pad 400, so that the rubber pad 400 approaches and tightly adheres to the annular rubber sealing band 100. At this time, the rubber pad 400 covers the splicing position on the outside of the annular rubber sealing band 100, so that the sealing effect of the annular rubber sealing band 100 can be improved, and external gas, lubricating oil or other liquids can be prevented from leaking inward through the splicing position on the outside of the annular rubber sealing band 100.

[0040] When the device needs to be disassembled, the knob 301 is reversely rotated to drive the threaded rod 303 to disengage from the first threaded sleeve 304 and the second threaded sleeve 305. The first protrusion 201 is pried up and pulled outward to disassemble the annular rubber sealing band 100, which has low operation difficulty.

[0041] The above is only the preferred embodiment of the present utility, and it should be pointed out that, for ordinary skilled persons in the art, without departing from the principle of the present utility, a number of improvements and refinements can be made, which should also be regarded as the protection range of the present utility. The structures, devices and operation methods not specifically described and explained in the present utility are implemented according to the conventional means in the art, unless otherwise specified and limited.
