[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0026] The following is combined with Figure 2-Figure 3 A waterproof structure of a sealing wheel provided by the utility model is described in detail.

[0027] Combination Figure 2 The embodiment of the utility model proposes a sealing wheel waterproof structure, which includes: a sealing wheel body 1, a bearing member 2, a spindle 3, a first cover body 4, an oil seal member 5, a waterproof ring 6, a sealing ring 7 and a second cover body 8. The bearing member 2 is arranged inside the sealing wheel body 1, the spindle 3 is axially penetrated at the center of the sealing wheel body 1 and combined with the bearing member 2, the first cover body 4 cooperates to cover the rear end of the sealing wheel body 1; the oil seal member 5 is arranged between the bearing member 2 and the first cover body 4, the waterproof ring 6 is arranged between the first cover body 4 and the sealing wheel body 1; the sealing ring 7 is arranged between the oil seal member 5 and the spindle 3, and the second cover body 8 is threadedly pressed on the front end of the sealing wheel body 1.

[0028] That is to say, the inside of the crimping wheel body 1 is hollow to form a receiving chamber for accommodating the bearing member 2, and the spindle 3 is arranged in the bearing member 2 in the receiving chamber. The bearing member 2 in the receiving chamber is sealed by the first cover body 4 and the second cover body 8. After the sealing, the first cover body 4 and the outer wall of the crimping wheel body 1 are sealed by the waterproof ring 6, the connection between the first cover body 4 and the spindle 3 is sealed by the oil seal 5, and the oil seal 5 and the spindle 3 are sealed by the sealing ring 7. In addition, the second cover body 8 is assembled at the front end of the crimping wheel body 1 in the form of a threaded gland, which can improve the waterproof effect of the connection between the second cover body 8 and the crimping wheel body 1.

[0029] Therefore, according to a waterproof structure of a sealing wheel in an embodiment of the utility model, the sealing wheel is triple-sealed by means of an oil seal 5, a waterproof ring 6 and a sealing ring 7, and the second cover body 8 is installed in the form of a threaded gland, thereby improving the waterproof effect of the overall assembly of the sealing wheel, and the bearing is not easy to transmit, thereby increasing the service life of the bearing, and further increasing the service life of the sealing wheel.

[0030] Specifically, the waterproof ring 6 is closely attached between the inner wall of the first cover body 4 and the outer wall of the crimping wheel body 1. It can be understood that the first cover body 4 covers the rear end of the crimping wheel body 1, and the first cover body 4 has a horizontal plate body that matches the rear end surface of the crimping wheel body 1, and also has a vertical plate body that matches the side surface of the crimping wheel body 1, and the waterproof ring 6 is arranged between the vertical plate body and the side surface of the crimping wheel body 1 opposite thereto to perform waterproof sealing at this position.

[0031] More specifically, combined with Figure 3 The waterproof ring 6 has a conical lip 61, and the lip 61 is closely attached to the outer wall of the sealing wheel body 1. The waterproof ring 6 has a conical lip 61, so that the waterproof ring 6 is a thin waterproof ring as a whole. The thin waterproof ring does not occupy space, and its lip 61 is thin and sharp, which can reduce the friction coefficient, and the sealing wheel will not heat up when used for a long time, thereby increasing the service life.

[0032] Furthermore, the outer surface of the main body of the waterproof ring 6 is closely attached to the inner wall of the first cover 4, and the lip 61 is arranged obliquely downward relative to the main body of the waterproof ring 6. In this way, the waterproof effect of the waterproof ring 6 can be improved.

[0033] The oil seal 5 includes a skeleton oil seal 51 and an oil seal bushing 52. The oil seal bushing 52 is sleeved on the spindle 3, and the skeleton oil seal 51 is arranged between the oil seal bushing 52 and the inner side wall of the crimping wheel body 1. The oil seal bushing 52 is used to install and position the skeleton oil seal 51. The skeleton oil seal 51 is used to make it a thin oil seal as a whole. While improving the sealing performance, it has a certain adaptability to the vibration of the machine and the eccentricity of the spindle 3.

[0034] More specifically, the skeleton oil seal 51 has a first sealing lip 511 and a second sealing lip 512 which are tightly attached to the outer wall of the oil seal bushing 52. The first sealing lip 511 is located above the second sealing lip 512, and the second sealing lip 512 is radially separated from the body of the skeleton oil seal 51, so that the skeleton oil seal 51 is thin as a whole. The setting of the first sealing lip 511 and the second sealing lip 512 can improve the sealing performance of the skeleton oil seal 51.

[0035] Further, the sealing ring 7 is an O-ring, and the O-ring is arranged between the spindle 3 and the oil seal bushing 52. In this way, the contact position between the spindle 3 and the oil seal bushing 52 can be sealed.

[0036] As for the second cover 8, when the second cover 8 is used to position the bearing component 2, the fine-pitch threaded cover can improve the waterproof effect of the front end surface of the bearing component 2, and the bearing component 2 will not move easily.

[0037] In addition, the spindle 3 is provided with an annular step 31 abutting against the outer surface of the first cover 4 at a position corresponding to the first cover 4. The spindle 3 abuts against the limiting bearing member 2 at one end adjacent to the second cover 8 through bolts and a connecting plate.
