Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, and particularly relates to a sealing ring resistant to wrinkles and leakage. Background Art

[0002] Axial sealing rings are generally formed by molding and vulcanizing silicone rubber materials. In new energy vehicle battery boxes and energy storage battery systems, they are commonly used to fit quick-connect water-cooled joints with different pipe diameters to play a sealing role.

[0003] Currently, the axial sealing of water-cooled joints is mainly achieved by the frictional contact between the cylindrical inner wall of the sealing ring and the outer wall of the joint, and the flange and the box body frame are in contact for sealing; theoretically, the contact area between this structure and the water-cooled joint is very large, but wrinkles are easily generated due to improper axial assembly during the assembly process, resulting in leakage.

[0004] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure, and thus it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to design a sealing ring that can effectively improve the drawback of easy wrinkling caused by large-area contact, so as to solve the above deficiencies in the technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a sealing ring resistant to wrinkles and leakage, used for axial sealing of the installation hole of a water-cooled joint on a box body frame, including a sleeve sleeved outside the water-cooled joint, and a flange integrally formed at the end of the sleeve. The flange and the inner peripheral surface of the sleeve have a plurality of annular ribs distributed in an array, and a recessed part is formed between two adjacent annular ribs. The part of the annular rib in contact with the outer peripheral surface of the water-cooled joint forms a raised part, and each raised part has a corresponding contact surface width when in contact with the outer peripheral surface of the water-cooled joint.

[0007] Preferably, the plurality of annular ribs distributed in an array are equally spaced.

[0008] Preferably, the number of the annular ribs is set to 3, one of which is located on the inner peripheral surface of the flange, and the other two are located on the inner peripheral surface of the sleeve.

[0009] Preferably, the cross-sectional shape of the annular rib is integrally set as U-shaped, 冂-shaped or semi-circular.

[0010] Preferably, the annular ribs are all in interference fit with the water-cooled joint;

[0011] The interference fit helps to improve the sealing effect during the installation of the water-cooled joint.

[0012] Preferably, the contact surface width of the raised portions on the front and rear two annular ribs among the three annular ribs when they contact the water cooling joint is 0.2 mm, and the contact surface width of the raised portion on the middle annular rib when they contact the water cooling joint is 0.5 mm.

[0013] Preferably, the recessed portion and the adjacent side wall of the annular rib have a rounded transition.

[0014] Preferably, the flange has a compression of more than 30% when under pressure;

[0015] The sealing ring flange position is designed to retain 30% compression, and a pressing force is applied to the box frame through the pressing block, which can provide a double sealing effect for the box.

[0016] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0017] 1. This product uses three equally spaced annular ribs to form an interference fit with the outer peripheral surface of the water-cooling joint to tighten and seal to prevent leakage;

[0018] 2. This product uses the raised and recessed parts on the sleeve and flange to ensure that when wrinkles are generated due to improper assembly, wrinkles will occur on the recessed part, while wrinkles will not occur on the raised part, ensuring that the fastening and sealing effect of the annular rib can be achieved normally without causing leakage;

[0019] 3. This product has three annular convex ribs, so that when one of the annular convex ribs fails to play a role of tightening and sealing due to wrinkles or other factors in special circumstances, the other two annular convex ribs can still play a role of tightening and sealing, playing a role of insurance;

[0020] 4. By retaining 30% of the compression amount in the design of the sealing ring flange position, a pressing force is given to the box frame through the existing pressure block, and at the same time, a double sealing effect can be provided to the box frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this application.

[0029] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings in the specification and specific embodiments.

[0030] Embodiment:

[0031] As Figure 1-Figure 3 shown, it includes a sleeve 1 sleeved outside the water-cooled joint, and a flange 2 integrally formed at the end of the sleeve 1. The flange 2 and the inner peripheral surface of the sleeve 1 have three equally spaced ring-shaped ribs 3. The ring-shaped ribs 3 are all in interference fit with the water-cooled joint. The cross-sectional shape of the ring-shaped rib 3 is integrally set as U-shaped, 冂-shaped or semi-circular. A depression 4 is formed between two adjacent ring-shaped ribs 3. The part of the ring-shaped rib 3 in contact with the outer peripheral surface of the water-cooled joint forms a protrusion 5. The contact surface width when the front and rear protrusions 5 are in contact with the water-cooled joint is 0.2 mm, and the contact surface width when the middle protrusion 5 is in contact with the water-cooled joint is 0.5 mm.

[0032] When the sealing ring is installed on the mounting hole of the box frame, the water-cooled joint is inserted into the sleeve 1 and the flange 2 and installed in the sleeve 1 and the flange 2 by interference fit. When the ring-shaped rib 3 is in interference fit with the water-cooled joint, certain deformation compression will occur. The lateral deformation widens the contact surface width when the protrusion 5 is in contact with the water-cooled joint, forming three surface contacts with the outer peripheral surface of the water-cooled joint, exerting a greater clamping force on the outer peripheral surface of the water-cooled joint and achieving a further fastening effect;

[0033] When wrinkles occur during installation, since the combined thickness of the sleeve 1 and the annular convex rib 3 is greater than the thickness of the sleeve 1 itself, and the recessed portion 4 is not in direct contact with the outer peripheral surface of the water-cooling joint, wrinkles will cause the portion of the sleeve 1 with the recessed portion 4 to wrinkle and bend, without affecting the sealing connection of the annular convex rib 3 on the water-cooling joint.

[0034] If one of the annular convex ribs 3 is wrinkled due to installation problems and fails to play a sealing role, the other two annular convex ribs 3 can play a sealing role and achieve a safety purpose.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
