Description

Technical Field

[0001] The utility model relates to the technical field of washers, in particular to a Y-shaped skeleton rubber washer. Background Art

[0002] Rubber gaskets are annular parts made of rubber materials with elasticity and sealing functions. They are widely used in many fields such as machinery, automobiles, aviation, and construction, especially in components such as engines, transmissions, water tanks, oil tanks, and hydraulic systems.

[0003] At present, a Chinese patent discloses a rubber gasket (publication number CN209430655U). Although the patent improves the pressure resistance of the rubber gasket through an internal reinforcement structure, when the rubber gasket is used outdoors, the external wind and rain will accelerate the aging rate of the rubber itself, which will gradually weaken the elasticity of the rubber, which will increase the probability of damage to the rubber gasket. In addition, the reinforcement structure also sacrifices part of the elasticity of the rubber gasket, exacerbating the probability of cracking and damage of the rubber gasket under impact.

[0004] Therefore, a Y-shaped skeleton rubber gasket is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a Y-shaped skeleton rubber gasket in order to solve the above problems, thereby improving the problem that the existing rubber gasket is easily damaged, resulting in reduced performance.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme. A Y-shaped frame rubber gasket comprises: a rubber ring and an elastic Y-shaped frame, wherein the elastic Y-shaped frame is embedded and installed inside the rubber ring; a repair device, wherein the repair device is arranged between the rubber ring and the elastic Y-shaped frame; the repair device comprises a capsule, wherein the capsule is fixedly connected between the rubber ring and the elastic Y-shaped frame, and the interior of the capsule is filled with sealant. When the rubber ring is cracked and damaged, since the capsule is fixed inside the rubber ring, the tension generated by the rubber ring after the cracking will also tear the nearest capsule. When the capsule is torn, the sealant flows along the broken part of the capsule to the crack connected with it, which can bond the crack of the rubber ring together and repair the rubber ring by itself. This can not only prevent the rubber ring from continuing to crack to avoid the crack from gradually increasing, but also prolong the effective service life of the rubber ring, and at the same time, it does not require the staff to actively maintain it, thereby reducing the labor intensity of the staff, and the staff can judge the use of the rubber ring according to the repair area of ​​the sealant, so that the staff can perform corresponding evaluation or replacement operations.

[0007] Preferably, the number of the repair devices is not less than ten, and the repair devices are distributed in a ring shape around the axis of the rubber ring between the rubber ring and the elastic Y-shaped frame, which can increase the effective repair range of the rubber ring and further extend the effective service life of the rubber ring.

[0008] Preferably, the surface of the elastic Y-shaped skeleton is provided with evenly distributed grooves, and the capsule is embedded and installed inside the grooves. The grooves can locate the position of the capsule, so that the staff can cover and wrap the capsule at the same time as the rubber ring is wrapped around the elastic Y-shaped skeleton, thereby reducing the production difficulty of the Y-shaped skeleton rubber gasket.

[0009] Preferably, the capsule is spherical in shape, the cross-sectional shape of the groove is arc-shaped, and the diameter of the capsule is larger than the maximum inner diameter of the inner side of the groove, which can make the force on the capsule more balanced to ensure that the capsule can be effectively torn.

[0010] Preferably, the corners of the connection between the groove and the elastic Y-shaped frame are rounded, which can reduce the probability of the groove scratching the capsule and avoid premature loss or solidification of the sealant.

[0011] Preferably, a cavity is provided inside the capsule, and the cavity is filled with compressed gas. When the capsule is torn, the pressure inside the capsule drops suddenly, and the compressed gas can squeeze the sealant inside the capsule through the cavity, which can quickly squeeze the sealant into the corresponding crack, thereby reducing the probability of the sealant being retained inside the capsule to improve the effective utilization rate of the sealant. Even if the crack is above the capsule, the sealant can effectively fill the gap, which effectively expands the sealing range of the sealant, thereby improving the practicability of the repair device.

[0012] Preferably, the cavity is arranged on the side of the sealant facing the elastic Y-shaped frame, which can push the sealant toward the side away from the elastic Y-shaped frame to increase the repair rate of the gap on the surface of the rubber ring.

[0013] Preferably, the compressed gas is an inert gas material component.

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

[0015] 1. When the rubber ring is cracked and damaged, the tensile force generated by the crack will also tear the nearest capsule. When the capsule is torn, the sealant flows along the broken part of the capsule to the crack connected with it, which can bond the crack of the rubber ring together and repair the rubber ring by itself. This can not only prevent the rubber ring from continuing to crack, so as to avoid the gradual increase of cracks, thereby extending the effective service life of the rubber ring, but also does not require the staff to take the initiative to maintain it, reducing the labor intensity of the staff, and the staff can judge the use of the rubber ring according to the repair area of ​​the sealant, so that the staff can carry out corresponding assessment or replacement operations;

[0016] 2. When the capsule is torn, the pressure inside the capsule drops suddenly, and the compressed gas can squeeze the sealant inside the capsule through the cavity, which can quickly squeeze the sealant into the corresponding crack, which not only reduces the probability of the sealant being retained inside the capsule to improve the effective utilization rate of the sealant, but also even if the crack is above the capsule, the sealant can effectively fill the gap, which effectively expands the sealing range of the sealant and thereby improves the practicability of the repair device.

[0022] 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.

[0023] When implementing: Figure 1-4As shown, a Y-shaped skeleton rubber gasket comprises: a rubber ring 1 and an elastic Y-shaped skeleton 2, wherein the elastic Y-shaped skeleton 2 is embedded and installed inside the rubber ring 1; a repair device 3, wherein the repair device 3 is arranged between the rubber ring 1 and the elastic Y-shaped skeleton 2; the repair device 3 comprises a capsule 31, wherein the capsule 31 is fixedly connected between the rubber ring 1 and the elastic Y-shaped skeleton 2, and the interior of the capsule 31 is filled with a sealant 32; the number of the repair devices 3 is not less than ten, and the repair devices 3 are distributed in a ring shape around the axis of the rubber ring 1 between the rubber ring 1 and the elastic Y-shaped skeleton 2; the surface of the elastic Y-shaped skeleton 2 is provided with evenly distributed grooves 21, and the capsule 31 is embedded and installed inside the groove 21; the shape of the capsule 31 is spherical, the cross-sectional shape of the groove 21 is arc-shaped, and the diameter of the capsule 31 is greater than the maximum inner diameter of the inner side of the groove 21; the corners of the connection between the groove 21 and the elastic Y-shaped skeleton 2 are rounded.

[0024] like Figure 4 As shown, a cavity 311 is provided inside the capsule 31, and the cavity 311 is filled with compressed gas; the cavity 311 is arranged on the side of the sealant 32 facing the elastic Y-shaped frame 2; the compressed gas is an inert gas material component;

[0025] When the capsule 31 is torn, the pressure inside the capsule 31 drops suddenly, and the compressed gas can squeeze the sealant 32 inside the capsule 31 through the cavity 311, which can quickly squeeze the sealant 32 into the corresponding crack, which can not only reduce the probability of the sealant 32 being retained inside the capsule 31 to improve the effective utilization rate of the sealant 32, but also even if the crack is above the capsule 31, the sealant 32 can effectively fill the gap, which effectively expands the sealing range of the sealant 32, thereby improving the practicality of the repair device 3.

[0026] When the utility model is in use, after the rubber ring 1 is cracked and damaged, since the capsule 31 is fixed inside the rubber ring 1, the tension generated by the cracking of the rubber ring 1 will also tear the nearest capsule 31. When the capsule 31 is torn, the sealant 32 flows along the broken part of the capsule 31 to the crack connected thereto, which can bond the crack of the rubber ring 1 together and repair the rubber ring 1 by itself. This can not only prevent the rubber ring 1 from continuing to crack, so as to avoid the gradual increase of the crack, and thus extend the effective service life of the rubber ring 1, but also does not require the staff to actively maintain it, thereby reducing the labor intensity of the staff, and the staff can judge the use of the rubber ring 1 according to the repair area of ​​the sealant 32, so that the staff can perform corresponding evaluation or replacement operations.

[0027] It should be noted that the sealant 32 in the above description is a device with relatively mature application in the prior art, and the specific model can be selected according to actual needs, which will not be described in detail here.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
