Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing ring installation, in particular to a clamping mechanism for the rubber sealing ring installation. Background Art

[0002] A rubber sealing ring is a device used to prevent leakage of liquid or gas. It is usually made of elastic material and has a sealing function. It is widely used nowadays. Nowadays, when installing a rubber sealing ring, it is usually placed at the pipe connection port and installed by squeezing the connection between the pipes.

[0003] A search revealed an existing patent (publication number: CN217177389U) that discloses a rubber seal ring with an elastic snap-fit structure for quick assembly and disassembly. The seal ring comprises a main body mounted on a water pipe interface, with an upper cavity defined within the top of the main body and a lower cavity defined at the bottom of the main body. The seal ring also includes an outer protective shell integrally mounted on the outside of the main body, a first protrusion defined below the outer protective shell, the first protrusion integrally mounted on the outside of the bottom of the main body, a second protrusion defined below the first protrusion, a third protrusion defined below the second protrusion, and the third protrusion integrally mounted on the outside of the bottom of the main body. The main body is connected to an inner protective shell via a connecting rod. This rubber seal ring with an elastic snap-fit structure for quick assembly and disassembly offers excellent sealing performance and is easy to disassemble.

[0004] However, in the above scheme, after the rubber sealing ring is squeezed and installed, it will fit the water pipe interface more closely, improving the sealing and firmness after the snap-on installation. However, when the water pipe is not connected, the rubber sealing ring is still directly placed inside one of the water pipe interfaces. However, sometimes due to installation space limitations, the water pipe interface where the rubber sealing ring is placed cannot be connected vertically to the other interface. Once it tilts, the rubber sealing ring placed inside will slide or even fall out. The staff often needs to press it with one finger, move it to the other interface, and then release it for installation. However, this operation is relatively inconvenient, and there is still a possibility that the rubber sealing ring will fall, which is not conducive to the connection operation between the interfaces.

[0005] In view of this, the present invention proposes a snap-fit mechanism for installing a rubber sealing ring. Utility Model Content

[0006] The utility model provides a clamping mechanism for installing a rubber sealing ring, which solves the problems in the related art.

[0007] The technical solution of the utility model is as follows: a clamping mechanism for installing a rubber sealing ring, comprising a rubber ring body; cavities symmetrically provided at the upper and lower ends of the rubber ring body; hollow rubber rings symmetrically fixedly connected to the upper and lower ends of the surface of the rubber ring body, wherein one side of the hollow rubber ring is provided with a connecting hole connected to the interior of the cavity at equal angles; a fixing ring fixedly connected to the middle position of the surface of the rubber ring body; and an elastic sheet fixedly connected to the surface of the fixing ring at equal angles.

[0008] Preferably, the elastic piece is in an inverted L-shape, and one side of the bottom end of the elastic piece is a bevel.

[0009] Preferably, one side of the elastic sheet is fixedly connected with anti-slip protrusions at equal intervals, and the anti-slip protrusions are arc-shaped.

[0010] Preferably, grooves are formed at equal angles on the top and bottom ends of the rubber ring body, and the shape of the grooves is bowl-shaped.

[0011] Preferably, sealing strips are fixedly connected to the inner wall of the rubber ring body at equal intervals, and the cross-section of the sealing strip is in the shape of an isosceles trapezoid.

[0012] Preferably, fixing grooves are provided at both ends of the top end of the rubber ring body, and an elastic pull ring is fixedly connected to one side of the bottom wall of the fixing groove.

[0013] Preferably, the hollow rubber ring is in an O-shape, and is symmetrically distributed about the transverse center axis of the rubber ring body.

[0014] The beneficial effects of the utility model are:

[0015] In the present invention, the rubber ring body is placed into the inner wall of the water pipe interface. At this time, the elastic sheet is clamped to the inner wall of the interface, thereby causing the elastic sheet to deform so that the surface of the elastic sheet is tightly attached to the inner wall of the interface. At the same time, the arc-shaped anti-slip protrusion is used to further improve the clamping tightness between the surface of the elastic sheet and the inner wall of the interface, thereby achieving a firm placement of the rubber ring body and the inner wall of the interface, thereby preventing the rubber ring body inside the interface from accidentally falling off when the water pipes are connected, thereby improving the convenience of connecting two water pipes for users;

[0016] In the utility model, when the water pipe interface is connected to another water pipe interface, the rubber ring body will be squeezed. At this time, the bowl-shaped groove is used, so that when the water pipe joint is squeezed and connected with the groove, the groove will generate a certain suction force, further improving the tightness of the connection between the rubber ring body and the two joints. At the same time, the top and bottom ends of the rubber ring body are squeezed first, so that the cavity inside shrinks and part of the air is transported to the inside of the hollow rubber ring, so that the hollow rubber ring collides and further clings to the inner wall of the interface, thereby further improving the sealing between the rubber ring body and the inner wall of the interface, and at the same time, it can also improve the tightness of the outer surface of the rubber ring body and the inner wall of the interface, so as to facilitate its long-term and effective use.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The preferred embodiment of the clamping mechanism for installing the rubber sealing ring provided by the present invention is as follows: Figures 1 to 6The figure shows a snap-fit mechanism for installing a rubber sealing ring, comprising a rubber ring body 5; cavities 4 symmetrically defined at the upper and lower ends of the rubber ring body 5; hollow rubber rings 2 symmetrically fixedly connected to the upper and lower ends of the surface of the rubber ring body 5, with communicating holes formed at equal angles on one side of the hollow rubber ring 2 communicating with the interior of the cavity 4; a fixing ring 3 fixedly connected to the middle position of the surface of the rubber ring body 5; and elastic sheets 8 fixedly connected at equal angles to the surface of the fixing ring 3.

[0027] In this embodiment, the rubber ring body 5 is placed into the inner wall of the water pipe interface. At this time, the elastic sheet 8 is clamped against the inner wall of the interface, thereby causing the elastic sheet 8 to deform so that the surface of the elastic sheet 8 is tightly attached to the inner wall of the interface. At the same time, the arc-shaped anti-slip protrusion 7 is used to further improve the clamping tightness between the surface of the elastic sheet 8 and the inner wall of the interface, thereby achieving a firm placement of the rubber ring body 5 and the inner wall of the interface, thereby preventing the rubber ring body 5 inside the interface from accidentally falling off when the water pipe is connected.

[0028] In a further preferred embodiment of the present invention, the elastic piece 8 is in an inverted L-shape, and one side of the bottom end of the elastic piece 8 is a bevel.

[0029] In this embodiment, the inverted L-shaped elastic piece 8 with a beveled edge is used to make it easier for it to be clamped to the inner wall of the interface and easier to deform.

[0030] In a further preferred embodiment of the present invention, one side of the elastic sheet 8 is fixedly connected with anti-slip protrusions 7 at equal intervals, and the anti-slip protrusions 7 are arc-shaped.

[0031] In this embodiment, the arc-shaped anti-slip protrusion 7 is used to increase the engaging friction between the surface of the elastic sheet 8 and the inner wall of the interface.

[0032] In a further preferred embodiment of the present invention, grooves 1 are formed at equal angles on the top and bottom ends of the rubber ring body 5 , and the shape of the grooves 1 is bowl-shaped.

[0033] In this embodiment, the bowl-shaped groove 1 is used so that when the water pipe joint is squeezed and connected to the groove 1, the groove 1 will generate a certain suction force, further improving the tightness of the connection between the rubber ring body 5 and the two joints.

[0034] In a further preferred embodiment of the present invention, sealing strips 6 are fixedly connected to the inner wall of the rubber ring body 5 at equal intervals, and the cross-section of the sealing strips 6 is an isosceles trapezoid.

[0035] In this embodiment, the isosceles trapezoidal sealing strip 6 is used to improve the sealing performance between the inner wall of the rubber ring body 5 and the surface of the pipeline.

[0036] In a further preferred embodiment of the present invention, fixing grooves 9 are formed at both ends of the top of the rubber ring body 5 , and an elastic pull ring 10 is fixedly connected to one side of the bottom wall of the fixing groove 9 .

[0037] In this embodiment, the elastic pull ring 10 is used to facilitate the removal of the rubber ring body 5 from the inside of the water pipe interface through a hook.

[0038] In a further preferred embodiment of the present invention, the hollow rubber ring 2 is in an O-shape, and is symmetrically distributed about the transverse center axis of the rubber ring body 5 .

[0039] In this embodiment, an O-shaped hollow rubber ring 2 is used to improve the sealing performance between the outer surface of the rubber ring body 5 and the inner wall of the interface.

[0040] The working principle of this utility model is as follows: first, the rubber ring body 5 is placed inside a water pipe interface. At this time, the elastic sheet 8 is clamped to the inner wall of the interface, thereby causing the elastic sheet 8 to deform, so that the surface of the elastic sheet 8 is closely attached to the inner wall of the interface. At the same time, the arc-shaped anti-slip protrusion 7 is used to further improve the clamping tightness between the surface of the elastic sheet 8 and the inner wall of the interface, so that the rubber ring body 5 is firmly placed on the inner wall of the interface, thereby preventing the rubber ring body 5 inside the interface from accidentally falling off when the water pipe is connected;

[0041] When this water pipe interface is subsequently connected to another water pipe interface, the rubber ring body 5 will be squeezed. At this time, the bowl-shaped groove 1 is used to squeeze and connect the water pipe joint and the groove 1. The groove 1 will generate a certain suction force, further improving the tightness of the connection between the rubber ring body 5 and the two joints. At the same time, the top and bottom ends of the rubber ring body 5 are first squeezed, causing the cavity 4 to shrink and transport part of the air into the hollow rubber ring 2, so that the hollow rubber ring 2 collides and further adheres to the inner wall of the interface, thereby further improving the sealing between the rubber ring body 5 and the inner wall of the interface. At the same time, it can also improve the tightness between the outer surface of the rubber ring body 5 and the inner wall of the interface, facilitating its long-term and effective use.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
