Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a sealing component with dustproof effect. Background Technology

[0002] In the operation of many mechanical equipment, seals play a crucial role, not only preventing internal media leakage but also resisting the entry of external dust, particles, and other impurities. However, existing seal designs are ineffective at blocking the intrusion of fine dust particles. Common examples include O-rings, which rely solely on simple compression sealing. When faced with pressurized, dusty airflow, dust can easily enter the equipment through the minute gaps between the seal and the mating surface, affecting the overall sealing performance. Prolonged use can lead to airtightness issues and accelerate equipment aging and damage. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sealing element with dustproof effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dustproof seal includes a sealing ring, an inner connecting ring fixedly connected to the inner side of the sealing ring, inner extension rings fixedly connected to both sides of the inner connecting ring, a retaining mechanism for maintaining the shape of the inner extension ring on the side wall of the inner extension ring, a compression ring fixedly connected to the outer side of the sealing ring, the compression ring having an inner cavity, a blocking mechanism for external obstruction on the side wall of the compression ring, and a reinforcing mechanism for strengthening the sealing ring structure inside the sealing ring.

[0006] Preferably, the retaining mechanism includes a plurality of circumferentially arranged elastic strips fixedly connected to the inner side of the inner extension ring. The length ratio of the elastic strips to the width of the inner extension ring is 6:4. By setting compression rings and connecting rings on the inner and outer sides of the sealing ring, the sealing size of the sealing ring can be extended. At the same time, the inner and outer extension rings form an inwardly bent sealing structure on both the inner and outer sides of the pipe. This can achieve the effect of preventing dust from entering the sealing area in both directions at the pipe connection while assisting the sealing ring in sealing.

[0007] Preferably, the blocking mechanism includes two symmetrically arranged extended rings fixedly connected to the side wall of the extrusion ring, and multiple layers of equally spaced corrugated plates are fixedly connected to the outer side of the extended rings.

[0008] Preferably, the reinforcing mechanism includes an inner groove formed within a sealing ring, an inner ring within the inner groove, an inner steel ring within the inner ring, and two symmetrically arranged support rings fixedly connected to the side wall of the inner ring, the support rings being disposed within the inner groove.

[0009] Preferably, an outer steel ring is provided inside the inner cavity.

[0010] Preferably, both the inner and outer extension rings have arc-shaped cross-sections, and the arcs of the inner and outer extension rings are arranged opposite to each other.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. This utility model incorporates an inner connecting ring, a compression ring, an inner extension ring, an outer extension ring, and a corrugated plate. By setting the compression ring and connecting ring on the inner and outer sides of the sealing ring, the sealing dimension of the sealing ring can be extended. Simultaneously, the inner and outer extension rings form an inwardly curved sealing structure on both the inner and outer sides of the pipe, which, while assisting the sealing ring in sealing, also prevents dust from entering the sealing area in two directions at the pipe connection. 2. This utility model incorporates a corrugated plate, an inner steel ring, an outer steel ring, a support ring, and an elastic strip. The corrugated plate provides support for the outer extension ring, ensuring its strength. Together with the inner and outer steel rings and the elastic strip, they provide support strength for the sealing ring, compression ring, and inner extension ring, respectively, ensuring both strength and sealing performance while avoiding any impact on the sealing performance of the sealing ring due to compression.

Detailed Implementation

[0017] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Reference Figure 1-4 A dustproof sealing element includes a sealing ring 1, an inner connecting ring 2 fixedly connected to the inner side of the sealing ring 1, and inner extension rings 7 fixedly connected to both sides of the inner connecting ring 2. The cross-sections of the inner extension rings 7 and the outer extension rings 4 are both arc-shaped, and the arc shapes of the inner extension rings 7 and the outer extension rings 4 are arranged opposite to each other. By setting compression rings 3 and connecting rings on the inner and outer sides of the sealing ring 1, the sealing size of the sealing ring 1 can be extended. At the same time, the inner extension rings 7 and the outer extension rings 4 form an inwardly bent sealing structure on both the inner and outer sides of the pipe. While the auxiliary sealing ring performs sealing, it can simultaneously prevent dust from entering the sealing area in two directions at the pipe connection.

[0019] The inner extension ring 7 has a retaining mechanism on its side wall to maintain its shape. The retaining mechanism includes multiple circumferentially arranged elastic strips 8 fixedly connected to the inner side of the inner extension ring 7. The ratio of the length of the elastic strip 8 to the width of the inner extension ring 7 is 6:4, that is, the length of the elastic strip 8 is less than the total width of the inner extension rings 7 on both sides. At this time, the inner extension rings 7 on both sides can form elastic edges that contact the inner wall of the pipe. In this way, the sealing of the inner wall at the pipe connection can be guaranteed.

[0020] A compression ring 3 is fixedly connected to the outer side of the sealing ring 1. The compression ring 3 has an inner cavity 9 and an outer steel ring 12. The side wall of the compression ring 3 is provided with a blocking mechanism for external obstruction. The blocking mechanism includes two symmetrically arranged outer extension rings 4 fixedly connected to the side wall of the compression ring 3. Multiple layers of equally spaced corrugated plates 6 are fixedly connected to the outer side of the outer extension rings 4.

[0021] The sealing ring 1 is provided with a reinforcing mechanism for strengthening the structure of the sealing ring 1. The reinforcing mechanism includes an inner groove 5 opened in the sealing ring 1, an inner ring 10 in the inner groove 5, an inner steel ring 11 in the inner ring 10, and two symmetrically arranged support rings 13 fixedly connected to the side wall of the inner ring 10. The support rings 13 are arranged in the inner groove 5.

[0022] When using this utility model, such as Figure 1-4As shown, during use, the widths of the inner connecting ring 2 and the compression ring 3 are first set according to the thickness of the pipe. Through the compression deformation of the inner connecting ring 2 and the compression ring 3, the sealing ring 1 can be extended at the pipe connection. At this time, when the pipe compresses the sealing ring 1, the inner connecting ring 2 and the compression ring 3 are simultaneously compressed. At this time, the outer steel ring 12 inside the compression ring 3 is located outside the pipe through compression, providing support for the installation of the sealing ring 1 and ensuring the overall installation strength of the sealing ring 1. At this time, the inner extension ring 7, under the arc support of multiple elastic strips 8, maintains an arc bend towards the sealing ring 1, thus connecting with the pipe. The inner wall of the pipe is in contact with the outer wall, while the outer extension ring 4 on the outside is in arc-shaped contact with the outer wall of the pipe. Combined with multiple corrugated plates 6, dust can be blocked, preventing dust from entering the pipe through the connection between the inner and outer sides and affecting the sealing performance of the sealing ring 1, thus impacting the service life of the equipment. During this process, the hollow structure of the inner cavity 9 provides space for the compression deformation of the sealing ring 1. Simultaneously, the inner steel ring 11, while preventing compression deformation of the sealing ring 1 and ensuring sealing performance, provides support strength for the sealing ring 1, thereby guaranteeing the stability and sealing performance of the sealing ring 1. The above description is only a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
