Description

Technical Field

[0001] This utility model relates to the field of rubber seal technology, and in particular to a rubber seal that can be combined and connected. Background Technology

[0002] Rubber seals, as a widely used type of sealing element, work on the principle of filling and compensating for the gap between two elements to be sealed, relying on the excellent deformability of rubber itself, thereby blocking the leakage path of fluid and achieving a reliable sealing effect. These seals are commonly used in daily life and industrial scenarios, appearing in everything from common pipe connections to precision equipment components. Structurally, the core components of most mainstream rubber seals on the market today are various types of rubber rings.

[0003] While the above technologies achieve a sealing effect, the different widths of the different frustum rubbers make it difficult for traditional fixed-size retaining rings to adapt to various installation scenarios, resulting in inconvenience in use. Therefore, a combinable rubber seal is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a combinable rubber seal, including a frustum rubber 1, an upper retaining ring 2 that is tightly wrapped and limited by the top edge of the frustum rubber 1, the interior of the upper retaining ring 2 being consistent with the lower retaining ring, a lower half retaining ring 3 with the same interior as the lower second half retaining ring 4 being provided at the bottom of the frustum rubber 1, a lower second half retaining ring 4 with the same symmetrical structure as the lower second half retaining ring 3 being provided on the outer wall of the lower second half retaining ring 3, an installation hole 5 being provided at the top of the lower second half retaining ring 3 to facilitate fixing the seal to the equipment interface, a groove 7 being provided on the outer wall of the frustum rubber 1, a limiting installation component 8 being provided on the inner wall of the lower second half retaining ring 3, and a width adjustment component 6 being provided inside the lower second half retaining ring 3; The width adjustment component 6 includes a retaining ring 61 with a polished outer wall. The top of the retaining ring 61 has a groove 62 with a rounded bottom. An elastic ball 64 is elastically connected inside the groove 62 via a spring 63. The lower second half-retaining ring 4 has a sliding groove 66 with a width matching the thickness of the retaining ring 61. The sliding groove 66 has a limiting groove 65 with a hemispherical groove matching the diameter of the elastic ball 64. The outer wall of the retaining ring 61 is slidably connected inside the sliding groove 66. The top of the frustum rubber 1 is fixed to the upper retaining ring 2 by a snap-fit ​​mechanism, while its bottom is installed in conjunction with the lower second half-retaining ring 3. The lower second half-retaining ring 3 and the lower third half-retaining ring 4 are adjustablely connected via the width adjustment component 6. When the retaining ring 61 slides along the sliding groove 66, the elastic ball 64, under the action of the spring 63, engages with the limiting groove 65 at different positions, thereby achieving width adjustment and fixation between the two to adapt to different installation space requirements. The limiting installation component 8 further enhances the stability of the overall structure.

[0019] Reference Figures 2-4The outer wall of the elastic ball 64 is engaged inside the limiting groove 65. One end of the spring 63 is fixedly connected inside the groove 62. The spring 63 and the groove 62 are fixed by welding, which provides a solid fixing base for the spring 63 and prevents the spring 63 from falling out of the groove 62 during the extension and contraction process. The other end of the spring 63 is fixedly connected to the rear wall of the elastic ball 64. The rear wall of the retaining ring 61 is fixedly connected to the inside of the next half retaining ring 3. The retaining ring 61 and the next half retaining ring 3 are manufactured by an integral molding process, with no splicing gap between them, resulting in high structural strength. The limiting installation component 8 includes a retaining block 81, which is a wedge-shaped structural part made of engineering plastic with a rounded transition design at the front end. The inner wall of the second half retaining ring 4 has a slot 82, and the rear wall of the retaining block 81 is open to the groove. The return spring 83 is elastically connected inside the slot 82. One end of the return spring 83 is fixedly connected to the rear wall of the retaining block 81. The return spring 83 and the retaining block 81 are connected by a snap-fit, which is convenient for disassembly and easy for later maintenance and replacement. The other end of the return spring 83 is fixedly connected to the inside of the slot 82. Multiple sets of retaining blocks 81 are provided, and the multiple sets of retaining blocks 81 are distributed in a ring along the inner wall of the lower second half retaining ring 4 and the lower first half retaining ring 3. The outer wall of the retaining block 81 is engaged inside the retaining groove 7. When the lower first half retaining ring 3 and the lower second half retaining ring 4 are combined, the retaining block 81 pops out under the elastic force of the return spring 83. The multiple sets of ring-distributed retaining blocks 81 work together to form a uniform radial limit on the frustum rubber 1, ensuring a tight fit between the frustum rubber 1 and the retaining ring assembly. At the same time, the retaining groove 7 on the outer wall of the frustum rubber 1 matches the corresponding structure of the retaining ring assembly, enhancing the overall sealing performance and connection firmness of the seal. A reliable sealing effect is achieved through the synergistic action of each component.

[0020] Working Principle: During assembly, the top of the frustum rubber 1 is fixed to the upper retaining ring 2 by a snap-fit, while the bottom is installed in conjunction with the lower half retaining ring 3. The lower half retaining ring 3 and the lower second half retaining ring 4 are adjustablely connected by the width adjustment component 6. When the retaining ring 61 slides along the slide groove 66, the elastic ball 64 is engaged in the limiting groove 65 at different positions under the action of the spring 63, thereby realizing the width adjustment and fixation between the two to adapt to different installation space requirements. The limiting installation component 8 further enhances the stability of the overall structure. When the lower first half retaining ring 3 and the lower second half retaining ring 4 are combined, the retaining block 81 pops out under the elastic force of the return spring 83. Multiple sets of ring-shaped retaining blocks 81 work together to form a uniform radial limit on the frustum rubber 1, ensuring a tight fit between the frustum rubber 1 and the retaining ring assembly. At the same time, the retaining groove 7 on the outer wall of the frustum rubber 1 cooperates with the corresponding structure of the retaining ring assembly, enhancing the overall sealing performance and connection firmness of the seal. A reliable sealing effect is achieved through the synergistic action of each component.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
