Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an O-type rubber sealing ring.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an O-type rubber sealing ring, comprising a fixed ring and a sealing ring body, the sealing ring body slides inside the fixed ring, a groove is provided inside the fixed ring, a spring is fixedly connected to the top of the groove, one end of the spring abuts against the bottom of the sealing ring body, a sliding groove is provided on the outer wall of the fixed ring, a limiting column is fixedly connected to the outer wall of the sealing ring body, and the limiting column slides in the sliding groove.

[0006] As a further description of the above technical solution:

[0007] The slide groove is L-shaped.

[0008] As a further description of the above technical solution:

[0009] The diameter of the sealing ring body is smaller than the diameter of the sealing ring body.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the sealing ring body is provided with a high temperature resistant protective layer.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, a mechanism for facilitating disassembly and installation is added to the O-type rubber sealing ring, and the positional relationship between the limit column and the slide groove on the outer wall of the sealing ring body is controlled. When the sealing ring needs to be repaired or replaced, the operator can complete the related work more quickly, simplifying the maintenance process and improving the maintenance efficiency.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-Figure 3 The utility model provides an embodiment: an O-type rubber sealing ring, comprising a fixing ring 1 and a sealing ring body 4, the sealing ring body 4 slides inside the fixing ring 1, a groove 5 is provided inside the fixing ring 1, a spring 6 is fixedly connected to the top of the groove 5, one end of the spring 6 abuts against the bottom of the sealing ring body 4, a sliding groove 2 is provided on the outer wall of the fixing ring 1, a limiting column 3 is fixedly connected to the outer wall of the sealing ring body 4, and the limiting column 3 slides in the sliding groove 2.

[0021] Among them, the slide groove 2 is L-shaped, and the L-shaped slide groove 2 provides a clear guide path for the disassembly and installation of the sealing ring, ensuring that the sealing ring can smoothly slide into the predetermined position during the disassembly and installation process. The diameter of the sealing ring body 4 is smaller than the diameter of the sealing ring body 4, and the outer wall of the sealing ring body 4 is provided with a high-temperature resistant protective layer, which can extend the service life of the sealing ring.

[0022] Working principle: when the sealing ring body 4 needs to be installed, the user can press the sealing ring body 4 to make the limiting column 3 on the outer wall of the sealing ring body 4 slide vertically in the slide groove 2 on the fixing ring 1, and the spring 6 is squeezed between the groove 5 and the sealing ring body 4, and the sealing ring body 4 is rotated. The sealing ring body 4 rotates inside the fixing ring 1, so that the limiting column 3 on the outer wall of the sealing ring body 4 makes a turning movement in the slide groove 2, so that the limiting column 3 is clamped in the slide groove 2 to achieve the limitation of the sealing ring body 4. When the sealing ring body 4 needs to be disassembled, the sealing ring body 4 is rotated to make the limiting column 3 on the outer wall of the sealing ring body 4 make a horizontal linear movement in the slide groove 2, and the spring 6 is squeezed between the groove 5 and the sealing ring body 4, and the sealing ring body 4 is pulled outward, so that the limiting column 3 on the outer wall of the sealing ring body 4 makes a vertical linear movement in the slide groove 2, so that the limiting column 3 is disengaged from the slide groove 2.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
