Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology, and in particular relates to a sealing ring that prevents displacement. Background Technology

[0002] Preventing displacement of sealing rings typically refers to sealing components used in high-pressure, high-temperature, or high-vibration environments. The purpose is to ensure that the sealing rings do not shift or fall off during installation or operation due to external factors (such as pressure changes, temperature fluctuations, vibrations, etc.), thereby maintaining sealing performance.

[0003] For example, Chinese patent CN220470618U discloses a sealing ring that prevents displacement. The double sealing structure of this device effectively increases the overall sealing performance. In conjunction with the external elastic anti-slip block, it can also limit the installation ring and prevent it from moving during use.

[0004] This patent uses the elasticity of a spring to push the push rod and the sealing ring, avoiding gaps and preventing the sealing ring from shifting at the connection. However, the spring's thrust can only increase the friction between the sealing ring and the sealed workpiece. When the external factors affecting the sealing ring exceed this friction, the sealing ring will still shift. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing ring that prevents displacement, so as to solve the problems mentioned in the background art. A sealing ring that prevents displacement can seal a sealing workpiece. The sealing workpiece has a first groove, and a plurality of protrusions are fixed in the first groove. The sealing ring is disposed in the first groove. The surface of the sealing ring has a plurality of second grooves, and the plurality of protrusions are respectively disposed in the plurality of second grooves. The cooperation between the protrusions and the second grooves limits the position of the sealing ring.

[0006] Preferably, the sealing ring has a top surface, a bottom surface, an inner wall, and an outer wall, and the second groove is sequentially formed on the top surface, the bottom surface, and the inner wall. The protrusion and the second groove are compatible and are both U-shaped.

[0007] Preferably, the inner wall of the sealing ring is provided with a third groove, which can generate a compressive force extending towards the top and bottom surfaces of the sealing ring when compression occurs between the sealing workpiece and the sealing ring.

[0008] Preferably, the third groove is a triangular groove.

[0009] Preferably, the outer wall of the sealing ring is provided with a fourth groove, and a plurality of elastic elements are installed inside the fourth groove. The elastic elements can provide additional compressive force to the top and bottom surfaces of the sealing ring.

[0010] Preferably, the fourth groove is convex in shape, and the elastic element is a spring.

[0011] Preferably, a skeleton is fixedly connected inside the sealing ring body, and the skeleton is used to increase the structural rigidity of the sealing ring body.

[0012] Preferably, the skeleton is made of a rigid material.

[0013] Preferably, the skeleton is made of metal.

[0014] Preferably, the skeleton is annular and extends along the contour of the sealing ring.

[0015] This application fixes several U-shaped protrusions in the first groove, and then uses several U-shaped second grooves opened on the surface of the sealing ring. Finally, the position of the sealing ring is limited by the cooperation between the protrusions and the second grooves, which prevents the sealing ring from shifting or falling off due to external factors and improves the stability of the sealing ring.

[0022] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0023] To prevent the sealing ring from shifting or falling off due to external factors (such as pressure changes, temperature fluctuations, vibration, etc.), this embodiment provides a sealing ring that prevents displacement.

[0024] like Figure 1As shown, the sealing workpiece 100 is the workpiece to be sealed. The workpiece is in the shape of a round rod. The sealing workpiece 100 has a first groove 110, which is an annular groove used to accommodate the sealing ring. Several protrusions 120 are fixed in the first groove 110. The protrusions 120 are square rods with a U-shaped shape, used to limit the position of the sealing ring (the specific method is described in detail below).

[0025] like Figures 2-3 As shown, the sealing ring is made of a circular elastic material, preferably rubber. The sealing ring has a top surface M1, a bottom surface M2, an inner wall M3, and an outer wall M4. The sealing ring is disposed in a first groove 110. A plurality of second grooves 210 are formed on the surface of the sealing ring. The second grooves 210 are rectangular strips with a U-shaped shape. The second grooves 210 are sequentially formed on the top surface M1, the bottom surface M2, and the inner wall M3. A plurality of protrusions 120 are respectively inserted into a plurality of second grooves 210. Through the cooperation between the protrusions 120 and the second grooves 210, the position of the sealing ring is defined, preventing the sealing ring from shifting or falling off due to external factors (such as pressure changes, temperature fluctuations, vibration, etc.), thereby improving the stability of the sealing ring.

[0026] To increase the tightness of the fit between the sealing ring and the first groove 110, a further solution is as follows: Figure 2 As shown, the inner wall M3 of the sealing ring has a third groove 220, which is a triangular groove. Due to the special shape of the triangular groove, when the sealing workpiece 100 and the sealing ring are squeezed, the contact surface between the sealing workpiece 100 and the sealing ring generates an additional squeezing force that extends towards the top surface M1 and the bottom surface M2 of the sealing ring, thereby increasing the tightness of the fit between the top surface M1 and the bottom surface M2 of the sealing ring and the first groove 110.

[0027] To increase the tightness of the fit between the top surface M1, the bottom surface M2 of the sealing ring, and the first groove 110, a further solution is as follows: Figures 2-3 As shown, the outer wall M4 of the sealing ring has a fourth groove 230, which is convex in shape. Several elastic elements 400 are installed inside the fourth groove 230. These elastic elements 400 are preferably springs. The elastic elements 400 can provide additional compressive force to the top surface M1 and bottom surface M2 of the sealing ring, thereby increasing the tightness of the fit between the top surface M1 and bottom surface M2 of the sealing ring and the first groove 110. For example... Figure 4 As shown, the ends of the spring are fixed to positions near the top surface M1 and the bottom surface M2, respectively, and the convex design of the fourth groove 230 can reduce the probability of the elastic element 400 detaching from the fourth groove 230.

[0028] To reduce the probability of the sealing ring shifting under pressure or vibration, further solutions include, for example... Figure 4As shown, a skeleton 300 is fixedly connected inside the sealing ring body 200. The skeleton 300 is annular and extends along the contour of the sealing ring. It is made of a rigid material, preferably metal. The skeleton 300 is used to increase the structural rigidity of the sealing ring body 200, so that the sealing ring body 200 can better maintain its shape and position in high pressure or vibration environment.

[0029] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
