Description

Technical Field

[0001] The utility model belongs to the technical field of sealing rings, and particularly relates to a vacuum adsorption type sealing ring. Background Art

[0002] The selection of the sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the use performance of the sealing ring, which is elastic and resilient; has appropriate mechanical strength, including expansion strength, elongation rate, tear strength, etc., has stable performance, is not easily swollen in the medium, has a small thermal shrinkage effect, is easy to process and form, and can maintain precise dimensions, does not corrode the contact surface, does not pollute the medium, etc. The most suitable and commonly used material that meets the above requirements is rubber. Therefore, most sealing rings are made of rubber materials. There are many varieties of rubber, and new rubber varieties are constantly emerging.

[0003] The existing sealing rings have the following problems during use:

[0004] 1. When the sealing ring is in use, when the outer side of its surface and the connecting component are squeezed, since their contact surface is usually smooth, it is easy to loosen during use, thereby resulting in poor sealing effect;

[0005] 2. When the sealing ring is in use, it mainly relies on the mutual extrusion and fitting between the sealing ring itself and the connecting component to achieve sealing. However, when the contact between the sealing ring and the connecting component is relatively smooth, the sealing effect is not good. Therefore, we propose a vacuum adsorption type sealing ring. Content of the Utility Model

[0006] The purpose of the utility model is to provide a vacuum adsorption type sealing ring to solve the technical problems raised in the background art.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A vacuum adsorption type sealing ring includes a sealing ring body. A first groove is opened in the upper part of the outer side of the surface of the sealing ring body, and a second groove is opened in the lower part of the outer side of the surface of the sealing ring body.

[0008] Preferably, fixing clamping grooves are opened at both the upper and lower ends of the sealing ring body, and a connecting extrusion mechanism is movably connected inside the fixing clamping grooves.

[0009] Preferably, a third groove is opened in the upper part of the inner side of the sealing ring body, and a fourth groove is opened in the lower part of the inner side of the sealing ring body.

[0010] Preferably, the connecting extrusion mechanism includes a compression rubber block, and a clamping block is provided at the bottom end of the compression rubber block.

[0011] Preferably, the bottom of the compressed rubber block fits with the inner side of the fixed card slot, and a card slot adapted to the card block is provided on the inner side of the fixed card slot.

[0012] Preferably, a fixed groove is formed in the top of the compressed rubber block.

[0013] A vacuum adsorption type sealing ring of the present utility model has the following advantages:

[0014] 1. For this vacuum adsorption type sealing ring, through the provided first groove, second groove, third groove and fourth groove, during the use process, when the sealing ring body and the connecting component are connected and extruded with each other, the whole sealing ring body will be extruded, causing the sealing ring body to deform, so that the inner sides of the first groove, second groove, third groove and fourth groove all fit with the surface of the connecting component, thereby achieving adsorption and fitting and improving the sealing effect.

[0015] 2. For this vacuum adsorption type sealing ring, through the provided fixed card slot and the connection and extrusion mechanism, when connecting with the connecting component, the connecting component extrudes the connection and extrusion mechanism, causing the connection and extrusion mechanism to move towards the inside of the sealing ring body, and then expanding the sealing ring body, so that the sealing ring body and the connecting component can be fully fitted and adsorbed, further improving the overall connection and sealing effect.

[0026] To better understand the purpose, structure, and function of the present invention, the following further describes a vacuum adsorption type sealing ring of the present invention in detail with reference to the drawings.

[0027] As Figures 1-3As shown in the figure, a vacuum adsorption type sealing ring of the utility model includes a sealing ring body 1. An upper part on the outer side of the surface of the sealing ring body 1 is provided with a first groove 2, and a lower part on the outer side of the surface of the sealing ring body 1 is provided with a second groove 3.

[0028] Both the upper and lower ends of the sealing ring body 1 are provided with fixed clamping grooves 4, and a connecting and pressing mechanism 5 is movably connected inside the fixed clamping grooves 4.

[0029] An upper part inside the sealing ring body 1 is provided with a third groove 6, and a lower part inside the sealing ring body 1 is provided with a fourth groove 7. When the sealing ring body 1 is subjected to extrusion, the sealing ring body 1 will deform, so that the inner sides of the third groove 6 and the fourth groove 7 are in fit with the connecting component, improving the connection sealing performance.

[0030] The connecting and pressing mechanism 5 includes a compression rubber block 8. A clamping block 9 is arranged at the bottom end of the compression rubber block 8. When the compression rubber block 8 is subjected to extrusion, the bottom of the compression rubber block 8 is extruded into the inside of the fixed clamping groove 4, causing extrusion and expansion of the sealing ring body 1, so that the sealing ring body 1 is tightly connected and fitted with the connecting component.

[0031] The bottom of the compression rubber block 8 is mutually in fit with the inside of the fixed clamping groove 4. A clamping groove adapted to the clamping block 9 is arranged inside the fixed clamping groove 4, facilitating that when assembling the whole, the bottom of the compression rubber block 8 can be stably stuck inside the fixed clamping groove 4, so as to carry out stable assembly.

[0032] A fixed groove 10 is arranged at the top of the compression rubber block 8, facilitating that when the compression rubber block 8 is subjected to extrusion, the compression rubber block 8 can be stably connected with the connecting component under the action of the fixed groove 10, and the operation is convenient.

[0033] The working principle of the vacuum adsorption type sealing ring: During use, place the whole at the end of the required connecting component, and then connect the connecting components. When the connecting components are connected, the compression rubber block 8 can be extruded, so that the bottom end of the compression rubber block 8 can be inserted into the inside of the fixed clamping groove 4, causing extrusion of the sealing ring body 1, so that the sealing ring body 1 deforms, and the sealing ring body 1 is tightly connected and fitted under the action of the second groove 3, the fixed clamping groove 4, the third groove 6 and the fourth groove 7. At the same time, when the top of the compression rubber block 8 is extruded and deformed, it can be mutually connected and adsorbed with the connecting component under the action of the fixed groove 10, improving the connection sealing effect of the whole, and the operation is convenient.

[0034] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
