[0002] The rubber sealing ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of a bearing and contacts with another ring or washer or forms a narrow labyrinth gap, thereby achieving the effect of sealing and preventing leakage. The existing sealing ring is generally a whole. In some special connection and disconnection mechanisms, a relatively thick rubber sealing ring is required. Since the sealing ring is relatively large and thick, its deformation is small. Therefore, when installing the sealing ring, a great effort is needed to deform the sealing ring so as to increase the inner ring of the sealing ring, and then the sealing ring can be assembled in place. Therefore, in the prior art, the sealing ring is relatively thick and is not easy to deform, which leads to difficult installation. SUMMARY

[0003] The utility model discloses to solve the technical problem that the existing sealing ring is not easy to install due to small deformation, and provides a silicon rubber sealing ring convenient to install, which comprises a sealing ring body, the sealing ring body comprises a fixed ring provided with a notch, the notch is arranged on the fixed ring, when assembling the fixed ring, the notch of the fixed ring is opened, so that the inner ring of the fixed ring is increased, the fixed ring is conveniently sleeved, an upper clamping groove is formed at the top end of the fixed ring, a lower clamping groove is formed at the bottom end of the fixed ring, the cross sections of the upper clamping groove and the lower clamping groove are trapezoidal in shape, and the upper clamping ring and the lower clamping ring are assembled. The upper clamping ring is detachably clamped in the upper clamping groove, the lower clamping ring is detachably clamped in the lower clamping groove, the bottom end of the upper clamping ring is fixed with an upper clamping block, the top end of the lower clamping ring is fixed with a lower clamping block, the upper clamping block and the lower clamping block are clamped in the notch on the fixed ring, openings are formed in the upper clamping ring and the lower clamping ring, the openings are arranged, the upper clamping ring and the lower clamping ring are assembled on the fixed ring, the sealing property of the fixed ring is improved, and the cross sections of the upper clamping block and the lower clamping block are trapezoidal in shape. The notch on the fixed ring is filled by the upper clamping block and the lower clamping block, and the sealing property of the fixed ring is improved.

[0004] Preferably, a vertical positioning groove is formed in the lower clamping block, and a vertical positioning column matched with the positioning groove is fixed to the bottom end of the upper clamping block, so as to facilitate positioning and installation.

[0005] Preferably, a baffle is arranged in the upper clamping groove of the fixed ring, and the baffle divides the upper clamping groove into two equal parts, and a baffle is also arranged in the lower clamping groove to divide the lower clamping groove into two equal parts.

[0006] Preferably, the fixed ring, the upper clamping ring and the lower clamping ring are all made of silicon rubber material.

[0007] The above scheme has the following advantages:

[0008] The retaining ring has a notch. When assembling the retaining ring, the notch is opened, increasing the inner circle of the retaining ring and making it easier to fit the retaining ring. The upper and lower retaining grooves have trapezoidal cross-sections, facilitating the assembly of the upper and lower retaining rings. Both the upper and lower retaining rings have openings, which facilitate the assembly of the upper and lower retaining rings onto the retaining ring. The upper and lower retaining blocks can fill the notch on the retaining ring, enhancing the sealing performance of the retaining ring. Attached Figure Description

[0014] like Figures 1-4 As shown, an easy-to-install silicone rubber sealing ring includes a sealing ring body 1. The sealing ring body 1 includes a retaining ring 11 with a notch. The notch on the retaining ring 11 allows the inner ring of the retaining ring 11 to be enlarged during assembly, making it easier to fit the retaining ring 11. The top of the retaining ring 11 has an upper retaining groove 12, and the bottom of the retaining ring 11 has a lower retaining groove 13. The cross-sections of the upper retaining groove 12 and the lower retaining groove 13 are both trapezoidal, which facilitates the assembly of the upper retaining ring 2 and the lower retaining ring 3. An upper retaining ring 2 is detachably engaged in the upper retaining groove 12, and a lower retaining ring 3 is detachably engaged in the lower retaining groove 13. An upper retaining block 21 is fixed to the bottom end of the upper retaining ring 2, and a lower retaining block 31 is fixed to the top end of the lower retaining ring 3. Both the upper retaining block 2 and the lower retaining block 3 are engaged at the notches on the fixing ring 11. Both the upper retaining ring 2 and the lower retaining ring 3 have openings. The openings facilitate the assembly of both the upper retaining ring 2 and the lower retaining ring 3 onto the fixing ring 11, improving the sealing performance of the fixing ring 11. Furthermore, both the upper retaining ring 2 and the lower retaining ring 3 have trapezoidal cross-sections. The upper retaining block 21 and the lower retaining block 31 can fill the notches on the fixing ring 11, enhancing the sealing performance of the fixing ring 11.

[0015] Preferably, the lower clamping block 31 is provided with a vertical positioning slot 32; the bottom end of the upper clamping block 21 is fixed with a vertical positioning column 22 matched with the positioning slot 32, facilitating positioning installation.

[0016] Preferably, the upper clamping groove 12 of the fixing ring 11 is provided with a baffle 4, which evenly divides the upper clamping groove 12 into two equal parts; the lower clamping groove 13 is also fixed with a baffle 14, which evenly divides the lower clamping groove 13 into two equal parts.

[0017] Preferably, the fixing ring 11, the upper clamping ring 2 and the lower clamping ring 3 are made of silicone rubber material.
