Description

Technical Field

[0001] The present application relates to the technical field of sealing, and in particular to a sealing sponge structure. Background Art

[0002] Sponge sealing structures are often used in the fields of automobiles, home appliances, aircraft, mechanical equipment, etc. The traditional way is to use strip sponges and ordinary frame sponges. The traditional strip sponges have seams at the joints, which are prone to air leakage, water leakage, and sound leakage, which ultimately affects the performance; the frame sponge has no seams, but the sponge cut out of the frame basically becomes waste, so the cost will be relatively high, and the corners where the sponge is pasted are basically rounded or beveled, and gaps are easily generated at the joints, which in turn leak sound, water, air leakage, etc., ultimately affecting the performance.

[0003] For example, a sealing sponge structure disclosed in the Chinese patent announcement number (CN211649044U) is characterized in that it includes a sealing strip, a cutting center line is provided in the middle of the sealing strip, splicing dovetails are provided at both ends of the sealing strip, and both sides of the sealing strip are provided with drawing corners protruding outwards respectively, and the sealing strip is stretched outwards from the drawing corners to form a frame-shaped sponge body. The sealing sponge structure of the utility model has a simple structure, low cost, good sealing performance, strong practicality and good application prospects.

[0004] However, in the prior art such as the above-mentioned patent, there is still a problem of poor combined sealing effect of the sealing strip. For example, in the prior art, the sealing sponge that is split into the sealing strip is combined and connected for sealing by cutting the center line and setting a dovetail, and there are drawn corners on both sides of the sealing strip, and the structure protrudes outward, resulting in that when the sealing strip is fitted and sealed on that side, when the rest of the surface is fitted, the corner part will be pressed inward and deformed, resulting in more gaps at that location, which affects the sealing performance of the sealing strip. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a sealing sponge structure having the advantages of good combined sealing effect, etc., and solves the problem of poor combined sealing effect of the sealing strip.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a sealing sponge structure, comprising a sealing strip, a connecting component is provided on the left side of the sealing strip, and a sealing component is provided on the inner wall of the sealing strip;

[0007] The connecting assembly includes a connecting plug, a limiting column and a splicing corner block. A storage groove is provided on the left side of the sealing strip, and one end of the connecting plug is fixed to the inner wall of the storage groove, and the other end of the connecting plug is fixed to the limiting column. Corner slots are provided on the left and right sides of the lower surface of the sealing strip, and the splicing corner block is inserted between the front and rear inner walls of the corner slot.

[0008] By adopting this technical solution, by setting a connecting component on the left side of the sealing strip, the structural integrity and stability of the sealing strip when assembled are ensured. The sealing component set on the inner wall provides a basic sealing effect, laying the foundation for further improving the sealing performance.

[0009] Furthermore, the length of the connecting plug block is equal to the thickness of the sealing strip, and the length of the limiting column is equal to the length of the connecting plug block.

[0010] The adoption of this technical solution helps to improve the stability of the connection components and the consistency of the overall structure.

[0011] Furthermore, the shape of the splicing corner block is L-shaped, and the splicing corner block is a hard sponge block.

[0012] By adopting this technical solution, additional structural reinforcement is provided to ensure that the connection is more secure.

[0013] Furthermore, a combination slot is provided on the right side of the sealing strip, and the thickness of the connecting plug is equal to the distance between the upper and lower inner walls of the combination slot.

[0014] By adopting this technical solution, the accuracy and tightness during assembly are ensured.

[0015] Furthermore, a limiting groove having a diameter equal to that of the limiting column is formed on the inner wall of the combined slot.

[0016] By adopting this technical solution, the limiting effect of the connecting component is enhanced, preventing the connecting component from shifting during use.

[0017] Furthermore, the sealing assembly includes a sealing inner layer, an intermediate sealing layer and a supporting layer, the sealing inner layer is fixed to the inner wall of the sealing strip, the intermediate sealing layer is bonded to the inner wall of the sealing inner layer, and the supporting layer is bonded to the inner wall of the intermediate sealing layer.

[0018] By adopting this technical solution, a more reliable sealing effect is provided, and each layer plays its unique role to enhance the overall sealing performance.

[0019] Furthermore, the sealing inner layer is a sealing sponge layer, and the supporting layer is a high-density sponge layer.

[0020] By adopting this technical solution, the sealing performance and supporting strength are optimized, ensuring the stability of the sealing strip under different pressures.

[0021] Furthermore, the cross-sectional shape of the middle sealing layer is O-shaped, and the middle sealing layer is a silicon foam sponge layer.

[0022] By adopting this technical solution, not only a good sealing effect is provided, but also the characteristics of the silicone foam sponge, such as good elasticity and recovery, are utilized to ensure the durability and reliability of the sealing effect.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. The sealing sponge structure, by setting up a connecting component and fixing the connecting plug and the limit column, enhances the connection stability between the sealing strips and forms a solid frame structure. The size matching of the combination slot and the limit slot ensures the precise alignment of the sealing strips when combined, avoiding misalignment and gaps. The modular design allows the sealing strips to be conveniently combined and disassembled through the connecting component. The use of the splicing corner block effectively fills the gap at the connection of the sealing strip, reducing the risk of sound leakage, water leakage and air leakage. When the sealing strip is used alone, the connecting plug and the limit column can be folded and stuffed into the storage tank, avoiding gaps when the sides are fitted, thereby improving space utilization and sealing performance.

[0025] 2. The sealing sponge structure provides a multi-layer sealing effect and enhances the sealing performance by setting up a sealing component, which is composed of a sealing inner layer, an intermediate sealing layer and a supporting layer. The intermediate sealing layer design helps to achieve uniform stress distribution on the sealing contact surface and improves the reliability of the seal. The multi-layer structure design improves the durability of the sealing component, so that it can withstand long-term use without losing sealing performance and can adapt to different contact surface shapes and pressure changes.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] See also Figure 1 A sealing sponge structure in this embodiment includes a sealing strip 1, a connecting component 2 is provided on the left side of the sealing strip 1, and a sealing component 3 is provided on the inner wall of the sealing strip 1.

[0032] See also Figure 2 In order to facilitate the combined connection of the sealing sponge, the connection assembly 2 in this embodiment includes a connection plug block 21, a limit column 22 and a splicing corner block 23. A storage groove 24 is provided on the left side of the sealing strip 1, and one end of the connection plug block 21 is fixed to the inner wall of the storage groove 24. When the sealing strip 1 is used alone, the connection plug block 21 and the limit column 22 can be folded and inserted into the storage groove 24. This design avoids the occurrence of gaps when the sides are fitted together, thereby improving the sealing performance when used alone. The other end of the connection plug block 21 is fixed to the limit column 22, and the left and right sides of the lower surface of the sealing strip 1 They are all provided with corner slots 25, and the splicing corner blocks 23 are inserted between the front and rear inner walls of the corner slots 25. When a frame-type sealing sponge needs to be formed, first, four sealing strips 1 are placed in place in the form of a frame, and a sealing strip 1 is taken out, and the connecting plug 21 and the limiting column 22 on it are inserted into the combined slot 26 and the limiting groove 27 on the other sealing strip 1. This step ensures the stability and accuracy of the connection by matching the sizes of the combined slot 26 and the limiting groove 27. According to the above method, all sealing strips 1 are connected in turn until a complete frame-shaped knot is formed.

[0033] In this embodiment, the length of the connecting block 21 is equal to the thickness of the sealing strip 1, the length of the limiting column 22 is equal to the length of the connecting block 21, and the shape of the splicing corner block 23 is L-shaped. After the frame structure is formed, since the corner slots 25 on the inner side of the sealing strip 1 correspond to each other, the splicing corner block 23 is taken out at this time and inserted into the corresponding two corner slots 25. The splicing corner block 23 is a hard sponge block. This step uses an L-shaped hard sponge block to effectively fill the gap at the connection of the seal 1, further improving the sealing performance. When a combination slot 26 is provided on the right side of the sealing strip 1, and the thickness of the connecting block 21 is equal to the distance between the upper and lower inner walls of the combination slot 26, a limiting slot 27 equal to the diameter of the limiting column 22 is provided on the inner wall of the combination slot 26. Through the connecting component 2, the sealing strip 1 can be easily combined into the required frame structure to adapt to different application scenarios.

[0034] See also Figure 3 In order to improve the sealing performance of the sealing sponge, the sealing component 3 in this embodiment includes a sealing inner layer 31, an intermediate sealing layer 32 and a supporting layer 33. The sealing inner layer 31 is fixed to the inner wall of the sealing strip 1. As a part of the sealing component 3, the sealing inner layer 31 is directly fixed to the inner wall of the sealing strip 1 to provide a first layer of sealing effect. The intermediate sealing layer 32 is bonded to the inner wall of the sealing inner layer 31. The intermediate sealing layer 32 has a silicon foam sponge layer with an O-shaped cross-section, which is bonded to the sealing inner layer 31 to form a sealed main body. The supporting layer 33 is bonded to the inner wall of the intermediate sealing layer 32. The sealing inner layer 31 and the supporting layer 33 provide fixing and supporting effects, and the O-shaped design of the intermediate sealing layer 32 ensures that they can fit tightly during docking and use, reducing gaps and improving sealing performance.

[0035] In this embodiment, the sealing inner layer 31 is a sealing sponge layer, the supporting layer 33 is a high-density sponge layer, and the cross-sectional shape of the middle sealing layer 32 is O-shaped. The O-shaped design can provide uniform compression force and enhance the sealing effect. The middle sealing layer 32 is a silicone foam sponge layer. The supporting layer 33 is bonded to the middle sealing layer 32 to provide additional support and strength for the sealing component 3, thereby ensuring the stability and durability of the sealing component 3 when under pressure.

[0036] The working principle of the above embodiment is:

[0037] (1) When a frame-type sealing sponge is required, four sealing strips 1 are first placed in place in a frame-like manner, and one sealing strip 1 is taken out, and the connecting plug 21 and the limiting column 22 on the sealing strip 1 are inserted into the combination slot 26 and the limiting groove 27 on another sealing strip 1. This step ensures the stability and accuracy of the connection by matching the size of the combination slot 26 and the limiting groove 27. According to the above method, all sealing strips 1 are connected in turn until a complete frame structure is formed. After the frame structure is formed, due to the position of the corner card slot 25 on the inner side of the sealing strip 1 Correspondingly, at this time, take out the splicing corner block 23 and insert it into the corresponding two corner slots 25. This step uses an L-shaped hard sponge block to effectively fill the gap at the connection of the seal 1, further improving the sealing performance. When the sealing strip 1 is used alone, its connecting block 21 and the limit column 22 can be folded and stuffed into the storage slot 24. This design avoids the appearance of gaps when the sides are fitted, thereby improving the sealing performance when used alone. Through the connecting component 2, the sealing strip 1 can be conveniently combined into the required frame structure to adapt to different application scenarios.

[0038] (2) As a part of the sealing component 3, the sealing inner layer 31 is directly fixed to the inner wall of the sealing strip 1 to provide the first layer of sealing effect. The middle sealing layer 32 has a silicone foam sponge layer with an O-shaped cross-section, which is bonded to the sealing inner layer 31 to form the main part of the seal. The O-shaped design can provide uniform compression force and enhance the sealing effect. The supporting layer 33 is bonded to the middle sealing layer 32 to provide additional support and strength for the sealing component 3, ensuring the stability and durability of the sealing component 3 when under pressure. The sealing inner layer 31 and the supporting layer 33 provide fixing and supporting effects, while the O-shaped design of the middle sealing layer 32 ensures a close fit during docking and use, reduces gaps, and improves sealing performance.
