Description

Technical Field

[0001] This utility model relates to the field of rubber seal technology, and in particular to a rubber seal with a buffer structure. Background Technology

[0002] In many practical working conditions, rubber seals are subjected to various impact forces. Road bumps, acceleration and deceleration generate vibrations and impacts, which are transmitted to the rubber seals. Instantaneous collisions and friction between components also generate impact forces that act on the seals. These impact forces may cause the rubber seals to shift or deform, damaging their sealing performance. Therefore, it is necessary to design a rubber seal with a buffer structure.

[0003] Traditional rubber seals mostly offer basic sealing functions and lack effective buffering measures against vibrations and impacts that pipelines may experience. The absence of specialized buffering devices to absorb and disperse impact forces makes these seals quite fragile when facing vibrations, making it difficult to maintain a good seal. They are prone to aging, hardening, and cracking, leading to premature seal failure. Installing an externally spring-loaded retractable sealing and shock-absorbing structure inside the connecting pipe can effectively buffer the impact of vibrations on the rubber seals. The spring absorbs and disperses the impact force, allowing the seal to maintain a stable position and shape even under vibration, tightly fitting the inner wall of the connecting pipe, improving the stability and reliability of the seal, and reducing the risk of leakage. Furthermore, traditional rubber seals often neglect the protection of the connecting pipe and the seal itself, lacking additional protective devices to resist external collisions, friction, and environmental factors, making them relatively fragile under complex operating conditions.

[0004] A sealing component with a buffer structure disclosed in publication number CN213176799U includes a mounting post, a first buffer module, and a second buffer module, which are mounted on the mounting post. The first buffer module includes a first mounting ring, a threaded ring, a first spring, and a first gasket. The first mounting ring includes a threaded ring mounting surface, a first fixing baffle, a first outer ring, a large inclined surface, an inner ring, a small inclined surface, and a second outer ring. The first gasket is located on the left side of the first mounting ring. This sealing component, by incorporating two buffer modules, allows the two components connected by the sealing component to move within a certain range without loosening, providing elasticity and stability to the connection. The inclusion of a threaded ring, fixing baffle, threaded groove, and threaded teeth allows for more diverse connections and simplifies the connection method.

[0005] While the aforementioned patent achieves the ability to buffer external impacts and increases the versatility of installation, the device lacks a protective measure for the structure itself. When the buffer device itself is subjected to impact or vibration, it may inevitably be damaged, affecting the subsequent sealing effect and efficiency. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The purpose of this invention is to provide a rubber seal with a buffer structure, which solves the problems mentioned in the background art regarding the basic sealing function, absorption and dispersion of impact force, difficulty in maintaining a good sealing state, and easy occurrence of aging, hardening, cracking and other phenomena.

The shock-absorbing mechanism includes a shrink-sealing ring installed on the outside of the through tube, a shrink-sealing pleat on the outside of the shrink-sealing ring, a shock-absorbing spring installed inside the shrink-sealing pleat, and the periphery of the shock-absorbing spring slidably connected to the inside of the connecting tube. The sealing mechanism includes a sleeve sleeved on the outside of the connecting tube, sleeves fixedly connected to both sides of the sleeve, and fixing strips fixedly connected to the periphery of both sides of the sleeve.

[0010] As a further embodiment of this utility model, the fixing strip has several fixing holes inside, and the fixing bolts pass through the fixing holes. The fixing bolts facilitate installation and connection.

[0011] As a further embodiment of this utility model, a sealing gasket is installed on the inner side of the through-tube. The sealing gasket is installed on the outer side of the middle section of the connecting tube. The sealing gasket serves to fill the internal gaps and provide shock absorption and sealing.

[0012] As a further embodiment of this utility model, a rubber ring is installed on the inner ring of the sleeve. The inner ring of the rubber ring is installed on the outside of the external pipe, and the rubber ring serves to achieve a connection and seal.

[0013] As a further embodiment of this utility model, an annular groove is provided on the inner right end of the connecting pipe. The inside of the annular groove is slidably connected to the outside of the shrink sealing ring. The annular groove facilitates the installation of the shrink sealing ring and increases the sealing effect.

[0014] As a further embodiment of this utility model, flanges A are fixedly connected to both the left and right sides of the connecting pipe. Several connecting holes are opened inside the flanges A, and connecting bolts pass through the connecting holes. The connecting bolts serve to connect and install the pipe.

[0016] (III) Beneficial Effects

[0017] This utility model provides a rubber seal with a buffer structure, which has the following beneficial effects:

[0018] 1. This rubber seal with a buffer structure, through the setting of the shock absorption mechanism, when the device is to be used, first install the connecting pipe on the external pipeline, and then install the through pipe together with the connecting bolts. A shrink sealing ring is installed on the outside of the through pipe, and a shock absorption spring is set on the outside of the shrink sealing ring. The shrink sealing ring and the shock absorption spring slide and are embedded in the annular groove inside the connecting pipe. This plays a role in relieving the internal pressure of the pipeline while sealing, avoiding the lack of a buffer device to absorb and disperse the impact force, which makes the seal very fragile, difficult to maintain a good sealing state, and prone to aging, hardening, cracking and other phenomena, leading to premature failure of the seal.

[0019] This rubber seal with a buffer structure, through the setting of the sealing mechanism, when the device is to be used, after the connecting pipe and the through pipe are installed on the external pipeline, a sealing gasket is installed at the middle section of the outer connecting pipe. Then, the sleeve is installed on the upper and lower sides of the connecting pipe. After that, the sleeve is tightened and fixed by passing the fixing bolt through the fixing strip. Since the sleeve is also installed on both sides of the sleeve, the sleeve is placed on the outside of the external pipeline, increasing the coverage area and improving the sealing performance. It plays the role of sealing externally and protecting the internal buffer mechanism. This avoids the problem that most traditional rubber seals neglect the protection of the connecting pipe and the seal itself, and lack additional protective devices to resist external collisions, friction and environmental factors, making the seal more vulnerable to complex working conditions.
