Description

Technical Field

[0001] The utility model belongs to the technical field of sealing elements, and in particular relates to a waterproof sealing rubber ring. Background Art

[0002] Sealing rubber rings are usually used to fill or seal the gap between two objects to prevent liquid, gas or other impurities from entering the gap, and also to prevent liquid or gas from leaking out.

[0003] The Chinese patent with publication number CN218523030U discloses a sealing rubber ring, which relates to the technical field of sealing rubber rings. The sealing rubber ring includes a rubber ring body, an arc-shaped docking groove, two grooves and two sealing extrusion edges. The arc-shaped docking groove is opened on the inner side surface of the rubber ring body, and the two grooves are opened on the inner side surface of the rubber ring body and are respectively located on the upper and lower sides of the arc-shaped docking groove. The two sealing extrusion edges are respectively arranged between the two grooves and the arc-shaped docking groove. The sealing extrusion edge is curved toward one side of the arc-shaped docking groove. The sealing rubber ring forms an extrusion force on the curved sealing extrusion edge through the protrusion on the mounting body, so that the sealing extrusion edge rotates toward the side away from the arc-shaped docking groove, so that the sealing extrusion edge squeezes the outer surface of the mounting body and produces deformation. In this way, the sealing rubber ring increases the sealing between the sealing rubber ring and the mounting body when a single protrusion is docked with the groove, further improving the practicality and use effect of the device.

[0004] The elasticity of the above-mentioned sealing rubber ring does not change during long-term use. At the same time, its elastic force gradually decreases over time, which easily creates a gap between the sealing surface and the sealing surface, resulting in leakage of media such as fluid or gas.

[0005] Therefore, a waterproof sealing rubber ring is proposed. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the present invention is to provide a waterproof sealing rubber ring to solve the technical defects mentioned in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A waterproof sealing rubber ring includes a sealing ring made of rubber material, with limit rings arranged on both sides of the sealing ring, and a displacement component arranged between the two groups of limit rings for reducing the distance to compress the sealing ring and improve the sealing degree with the sealing surface, and the inner cavity of one group of limit rings is provided with an anti-deflection component for preventing the limit ring from being displaced.

[0009] As a further solution of the present invention, the displacement assembly includes several groups of connecting columns fixedly installed on one side of one group of limiting rings. The connecting columns are arranged in a ring array. One end of the connecting column passes through the sealing ring and the other group of limiting rings in sequence and is fixedly connected to a threaded column. The surface of the threaded column is threadedly connected to a nut, and one side of the nut is tightly attached to the surface of the other group of limiting rings.

[0010] As a further solution of the present invention, the anti-deflection component includes grooves respectively opened on the upper and lower sides of one group of limit rings, and the inner arc surfaces on the upper and lower sides of one group of limit rings are provided with guide grooves, and the inner cavities of the two groups of guide grooves are respectively connected to the inner cavities of the corresponding side grooves, and the mouths of the guide grooves located in the grooves are connected to bolts through rotating connectors, and one ends of the two groups of bolts extend to the inner cavities of the corresponding side guide grooves respectively, and the screw surfaces of the bolts located in the guide grooves are threadedly connected with abutment blocks, and the two groups of abutment blocks are respectively slid up and down and connected to the inner cavities of the corresponding side guide grooves.

[0011] As a further solution of the present invention, the rotating connecting member includes bearings embedded in the openings of the two sets of guide grooves on one side facing each other, and the inner rings of the two sets of bearings are respectively sleeved on the necks of the corresponding side bolts.

[0012] As a further solution of the present invention, arc-shaped notches are provided on opposite sides of the two groups of abutment blocks, and rubber pads are bonded inside the arc-shaped notches.

[0013] As a further solution of the present invention, a wedge-shaped washer is sleeved on the surface of the threaded column located between the other set of limiting rings and the nut.

[0014] Compared with the prior art, the waterproof sealing rubber ring of the utility model has the following beneficial effects:

[0015] 1. When the rotating nut pushes the limit ring to move, the connecting columns of the annular array can ensure that the limit ring applies pressure to the sealing ring steadily, thereby achieving uniform compression of the sealing ring, causing the sealing ring to deform under pressure, so that it fits the sealing surface more closely, significantly improving the sealing degree with the sealing surface, and effectively preventing the leakage of media such as fluids or gases.

[0016] 2. By setting the anti-deflection component, rotating the bolt drives the abutment block to slide in the guide groove, so that the abutment block is in close contact with the fixed part of the sealing device, thereby generating friction to prevent the movement of the limit ring, and can limit the displacement of the limit ring in multiple directions.

[0017] 3. The provision of the rubber pad enhances the friction and fit between the abutment block and the sealing surface, and the rubber pad further improves the overall stability of the sealing device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] See attached Figure 1-4 As shown, an embodiment of the present invention provides a waterproof sealing rubber ring, including a sealing ring 100 made of rubber material, with limiting rings 101 arranged on both sides of the sealing ring 100, and a displacement component arranged between the two groups of limiting rings 101 for narrowing the distance to compress the sealing ring 100 and improve the sealing degree with the sealing surface, wherein the inner cavity of one group of limiting rings 101 is provided with an anti-deflection component for preventing the limiting ring 101 from being displaced, and the displacement component includes a plurality of groups of connecting columns 203 fixedly mounted on one side of one group of limiting rings 101, and the connecting columns 203 are arranged in a ring array, and one end of the connecting column 203 sequentially penetrates the sealing ring 100 and the other group of limiting rings 101 and is fixedly connected with a threaded column 200, and the surface of the threaded column 200 is threadedly connected with a nut 201, and one side of the nut 201 is tightly attached to the surface of the other group of limiting rings 101. By setting the displacement assembly, when the rotating nut 201 pushes the limit ring 101 to move, the connecting columns 203 of the annular array can ensure that the limit ring 101 smoothly applies pressure to the sealing ring 100, thereby achieving uniform compression of the sealing ring 100, causing the sealing ring 100 to be deformed under pressure, thereby fitting more closely to the sealing surface, significantly improving the sealing degree with the sealing surface, and effectively preventing leakage of media such as fluids or gases.

[0029] The anti-deflection assembly includes grooves 102 formed on the upper and lower sides of one set of limit rings 101. The inner arc surfaces of the upper and lower sides of one set of limit rings 101 are each provided with guide grooves 103. The inner cavities of the two sets of guide grooves 103 are connected to the inner cavities of the corresponding side grooves 102. The mouths of the guide grooves 103 located in the grooves 102 are connected to bolts 300 via rotating connectors. One end of the two sets of bolts 300 extends into the inner cavities of the corresponding side guide grooves 103. The screw surfaces of the bolts 300 located in the guide grooves 103 are threadedly connected to abutment blocks 302. The two sets of abutment blocks 302 are respectively slidably connected to the inner cavities of the corresponding side guide grooves 103. Through the provision of the anti-deflection assembly, rotating the bolts 300 drives the abutment blocks 302 to slide within the guide grooves 103, so that the abutment blocks 302 are in close contact with the fixed portion of the sealing device, thereby generating friction to prevent the movement of the limit ring 101, thereby limiting the displacement of the limit ring 101 in multiple directions.

[0030] The rotating connector includes bearings 301 embedded in the opposing openings of the two sets of guide slots 103. The inner rings of the two sets of bearings 301 fit over the necks of the corresponding bolts 300. The bearings 301 provide excellent rotational support when the bolts 300 need to rotate, significantly reducing friction between the bolts 300 and the openings of the guide slots 103.

[0031] The two sets of abutment blocks 302 are each provided with an arc-shaped notch 304 on the opposite side, and rubber pads 303 are bonded inside the arc-shaped notch 304 to enhance the friction and fit between the abutment blocks 302 and the sealing surface. The rubber pads 303 further improve the overall stability of the sealing device.

[0032] A wedge-shaped washer 202 is sleeved on the surface of the threaded column 200 located between the other set of limiting rings 101 and the nut 201 to effectively prevent the nut 201 from loosening due to vibration or other external forces during operation of the equipment.

[0033] When the embodiment of the present invention is used, one group of limit rings 101 is placed on the sealing surface, and then a tool is used to rotate the bolts 300 located in the upper and lower grooves 102 respectively. As the bolts 300 rotate, the abutment blocks 302 threadedly connected to the bolts 300 will slide downward in the guide groove 103 according to the direction of rotation of the bolts 300. The two groups of abutment blocks 302 will slide relative to each other until they respectively contact the sealing surfaces of the sealing device. An arc-shaped notch 304 is provided on the opposite side of the abutment blocks 302, and a rubber pad 303 is bonded inside the arc-shaped notch 304. When the abutment blocks 302 contact the fixed part, the rubber pad 303 can increase the friction when in contact with the fixed part, thereby effectively limiting the movement of the limit ring 101.

[0034] Then take out the sealing ring 100, put it on the sealing surface, and push the sealing ring 100 to one side so that the connecting column 203 on the surface of the limiting ring 101 passes through the sealing ring 100, then take out another set of limiting rings 101, and make its connecting column 203 pass through the limiting ring 101, then put a wedge washer 202 on the surface of the threaded column 200 fixedly installed at one end, then thread the nut 201 onto the surface of the threaded column 200, and make the wedge washer 202 abut against the surface of the limiting ring 101.

[0035] When the rubber ring ages after long-term use, resulting in a decrease in sealing, by rotating the nut 201, the nut 201 and the threaded column 200 are threadedly connected, and the nut 201 will move along the axial direction of the threaded column 200. One side of the nut 201 is close to the surface of the other set of limiting rings 101. As the nut 201 moves, it will apply a thrust to the other set of limiting rings 101, pushing this set of limiting rings 101 toward the direction close to the sealing ring 100. At this time, the distance between the two sets of limiting rings 101 will gradually decrease, and the sealing ring 100 located between them will be squeezed by the two sets of limiting rings 101, thereby being elastically deformed and compressed. This elastic deformation of the sealing ring 100 makes it more closely contacted with the sealing surface, thereby improving the sealing.

[0036] The above shows and describes the basic principles of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the scope of protection of the present invention.
