Description

Technical Field

[0001] This utility model relates to the field of sealing strip manufacturing technology, and in particular to a reinforced sealing strip. Background Technology

[0002] Sealing strips are elastic material products used to seal objects, making them difficult to open and preventing the leakage of liquids, gases, or dust. They also serve functions such as shock absorption, waterproofing, and dustproofing. They are made of various materials such as rubber, metal, and plastic and are widely used in various industries and daily life.

[0003] Patent CN218992333U discloses a sealing strip that is easy to remove, including a sealing strip, a U-shaped groove, a splicing insert, a positioning clip, an elastic support, a U-shaped cavity, and a support piece. The sealing strip has a U-shaped groove on its lower end face, and an elastic support is fitted inside the U-shaped groove. The splicing insert is symmetrically inserted into the left and right ends of the sealing strip, and a positioning clip is connected to the right end face of the splicing insert. The sealing strip has a U-shaped cavity on its upper side, and a support piece is fitted inside the U-shaped cavity.

[0004] In the above case, the sealing strip is secured to the inside of the object by a positioning clip and supported by an elastic support piece. However, relying solely on an elastic support piece to ensure the installation stability of the sealing strip, and the fact that the top of the sealing strip is too easily deformed, makes it unable to provide stable support, resulting in low practicality of the sealing strip.

[0005] Therefore, this utility model provides a reinforced sealing strip to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide a reinforced sealing strip to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reinforced sealing strip, comprising an insertion section, a sealing head fixedly connected to the top of the insertion section, a support assembly fixedly connected to the inner side of the insertion section, the support assembly comprising side pieces fixedly connected to both ends of the inner side of the insertion section, a plurality of support spring pieces fixedly connected sequentially from top to bottom between two side pieces, a plurality of inner holes opened on the inner side of the support spring pieces, a reinforcing assembly fixedly connected to the inner side of the sealing head, the reinforcing assembly comprising a reinforcing steel ring fixedly connected to the inner side of the sealing head, a plurality of connecting strips fixedly connected to the inner side of the reinforcing steel ring, a common ring fixedly connected between the plurality of connecting strips, an inner cavity opened inside the sealing head, a plurality of buffer rings fixedly connected to the inner side of the inner cavity, and an inner ring fixedly connected to the inner side of the buffer rings.

[0008] In a preferred embodiment, the width of the plug segment gradually decreases from top to bottom, the bottom end of the plug segment is arc-shaped, and the plug segment includes reinforcing blocks fixedly connected to both ends at the top, the reinforcing blocks being fixedly connected to the bottom of the sealing head.

[0009] In a preferred embodiment, the number of supporting springs is four, which are evenly distributed between the two side pieces, and the middle part of the supporting springs is bent upward.

[0010] In a preferred embodiment, the number of connecting strips is four, which are located on both sides of the upper and lower ends of the inner side of the reinforcing steel ring.

[0011] In a preferred embodiment, a number of compression rings are fixedly connected to the outer side of the plug segment, and the number of compression rings is six, which are evenly distributed on both sides of the plug segment.

[0012] In a preferred embodiment, a top strip is fixedly connected to the top end of the inner side of the plug segment, and the top strip is fixedly connected to the middle end of the bottom of the sealing head.

[0013] In a preferred embodiment, the inner cavity is located on the side of the sealing head away from the insertion section, and both the buffer ring and the inner ring are elliptical, with their orientations perpendicularly intersecting.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting an extrusion ring and a support component, enables the device to support both ends of the plug section through the cooperation of multiple support springs, thereby improving the stability of the plug section when it is snapped into the installation position. The extrusion ring further enhances the installation stability of the sealing strip through its compression support. The reduced width of the plug section, combined with its arc shape at the bottom, makes the sealing strip easier to install, thus improving the practicality of the device.

[0016] This utility model, by setting up a reinforcing component, an inner cavity, a buffer ring, and an inner ring, enables the reinforcing steel ring to reinforce and support the sealing head, preventing it from deforming too easily. The reinforcing steel ring is further supported by a connecting strip and a ring, increasing its supporting force. The combination of the inner cavity and the buffer ring not only saves materials but also buffers external impacts, avoiding excessive impact force and improving the service life and practicality of the device.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figures 1-3 This utility model provides a reinforced sealing strip, including an insertion section 1. A sealing head 2 is fixedly connected to the top of the insertion section 1, and a support assembly 3 is fixedly connected to the inner side of the insertion section 1. The support assembly 3 includes side pieces 301 fixedly connected to both ends of the inner side of the insertion section 1. A plurality of support spring pieces 302 are fixedly connected between the two side pieces 301 from top to bottom. A plurality of inner holes 303 are opened on the inner side of the support spring pieces 302. The width of the insertion section 1 gradually decreases from top to bottom, and the bottom end of the insertion section 1 is arc-shaped. The plug-in section 1 includes reinforcing blocks fixedly connected to both ends of the top, which are fixedly connected to the bottom of the sealing head 2. There are four supporting springs 302, which are evenly distributed between the two side pieces 301. The middle part of the supporting springs 302 is bent upward. There are six extrusion rings 4 fixedly connected to the outer side of the plug-in section 1, which are evenly distributed on both sides of the plug-in section 1. A top strip 9 is fixedly connected to the top end of the inner side of the plug-in section 1, which is fixedly connected to the middle end of the bottom of the sealing head 2.

[0024] When the bottom end of the plug segment 1 is inserted into the installation part, the outer compression ring 4 will contact the inner wall of the installation part and generate compression during the insertion process, thereby providing a preliminary sealing effect. At the same time, the support spring 302 will be compressed and deformed during the insertion process. After installation, the support spring 302 will press the two ends of the plug segment 1 to both sides, so that the two ends of the plug segment 1 are tightly fitted to the inner wall of the installation part.

[0025] The gradually narrowing width from top to bottom and the rounded bottom shape make it easier to insert the plug section 1 into the installation location, reducing resistance and friction during installation. This not only improves the ease of installation of the sealing strip but also significantly enhances its practicality in actual use.

[0026] By utilizing the coordinated action of multiple support springs 302, strong support can be provided to both ends of the plug segment 1, thereby effectively enhancing the snap-fit ​​stability of the plug segment 1 at the installation location. This design not only ensures that the sealing strip will not loosen or fall off due to external forces during use, but also greatly improves its overall structural reliability. During installation, the compression ring 4 is in close contact with the installation location and generates a certain elastic compression effect. This compression effect can not only fill the tiny gaps between the sealing strip and the installation location, but also effectively prevent gas or liquid leakage, thereby significantly improving the sealing performance. In addition, the uniform distribution design of the compression ring 4 can also ensure that the sealing strip is subjected to uniform support force in all directions, further enhancing its stability after installation.

[0027] Please see Figures 1-3 A reinforcing component 8 is fixedly connected to the inner side of the sealing head 2. The reinforcing component 8 includes a reinforcing steel ring 801 fixedly connected to the inner side of the sealing head 2. Several connecting strips 802 are fixedly connected to the inner side of the reinforcing steel ring 801. The same ring 803 is fixedly connected between the several connecting strips 802. An inner cavity 5 is opened inside the sealing head 2. Several buffer rings 6 are fixedly connected to the inner side of the inner cavity 5. An inner ring 7 is fixedly connected to the inner side of the buffer ring 6. There are four connecting strips 802, which are located on the upper and lower sides of the inner side of the reinforcing steel ring 801 respectively. The inner cavity 5 is located on the side of the sealing head 2 away from the insertion section 1. Both the buffer ring 6 and the inner ring 7 are elliptical, and the orientation of the buffer ring 6 and the inner ring 7 is perpendicular and staggered. Both the reinforcing component 8 and the support component 3 are made of elastic metal.

[0028] When an external object impacts the sealing head 2, the connecting strip 802 and the ring 803 support the reinforcing steel ring 801, and the reinforcing steel ring 801 supports the sealing head 2. The buffer ring 6 and the inner ring 7 can absorb the kinetic energy generated by the external impact and reduce the impact.

[0029] The reinforcing steel ring 801 provides strong reinforcement support for the sealing head 2, preventing it from easily deforming under external forces during use. This design not only ensures the stability of the sealing head 2 under high pressure or complex environments, but also greatly improves the overall structural strength of the sealing strip. The connecting strip 802 is evenly distributed on the inner side of the reinforcing steel ring 801 and forms a stable support network through its fixed connection with the ring 803. This structural design can not only disperse external forces, but also ensure that the reinforcing steel ring 801 has a uniform support effect in all directions, thereby further improving the pressure resistance and stability of the sealing strip.

[0030] The design of the inner cavity 5 cleverly reduces the amount of material used, lowers production costs, and lightens the overall weight of the sealing strip, making it easier to install and use. The buffer ring 6 provides additional cushioning for the sealing strip. When the sealing strip is subjected to external impact, the buffer ring 6 can effectively absorb and disperse the impact force, preventing the sealing head 2 from being damaged by excessive instantaneous impact. This cushioning design not only extends the service life of the sealing strip but also ensures its reliability and stability during long-term use.

[0031] The working principle and usage process of this utility model are as follows: The bottom end of the plug section 1 is inserted into the installation part. During the insertion process, the outer compression ring 4 will contact the inner wall of the installation part and generate compression, thereby providing a preliminary sealing effect. At the same time, the support spring 302 will be compressed and deformed during the insertion process. After installation, the support spring 302 will press the two ends of the plug section 1 to both sides, so that the two ends of the plug section 1 are tightly fitted with the inner wall of the installation part. When an external object impacts the sealing head 2, the connecting strip 802 and the ring 803 will support the reinforcing steel ring 801 and support the sealing head 2 through the reinforcing steel ring 801. The buffer ring 6 and the inner ring 7 can absorb the kinetic energy generated by the external impact and reduce the impact.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
