Description

Technical Field

[0001] This utility model relates to the field of sponge sealing technology, and in particular to an adjustable sponge sealing component. Background Technology

[0002] Sponge seals are annular seals used to form a seal at the joint of connectors, preventing media leakage or the entry of external impurities. Compared with traditional rubber seals, sponge seals have better elasticity and compressibility, are more adaptable to different shaped joint surfaces, ensure good sealing effect, and have better cushioning performance. They are widely used in many fields such as electronic products, automotive parts, and home appliances.

[0003] When using sponge seals, they are usually directly fitted onto the parts to be sealed. However, in the existing technology, since the height of the sponge seal is fixed, it is necessary to adjust the height of the sponge seal according to the height of the parts. For shorter parts, the sponge seal can be cut to fit, while for longer parts, it needs to be spliced ​​to lengthen it. However, the sealing performance is poor after splicing, and the operation is also inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing sponge seals are inconvenient to adjust according to the height of the parts to be sealed, and to propose an adjustable sponge seal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a sponge sealing component body, with an upper support ring plate and a lower support ring plate fixed at the upper and lower ends of the sponge sealing component body, respectively. A plurality of pull lines are fixed at equal intervals on the top surface of the lower support ring plate. Each pull line extends through the sponge sealing component body to the outside of the upper support ring plate. A placement groove is opened on the top of the sponge sealing component body outside each pull line. A rigid support plate is provided inside each placement groove. Each rigid support plate is fixed to the bottom surface of the upper support ring plate.

[0006] Preferably, the inner diameters of the upper and lower support ring plates are both larger than the inner diameter of the main body of the sponge seal, and the outer diameters of the upper and lower support ring plates are both smaller than the outer diameter of the main body of the sponge seal.

[0007] Preferably, the height of each pull line is greater than the sum of the heights of the sponge seal body and the upper support ring plate, and an auxiliary pull ring is fixed to one end of each pull line extending to the outside of the upper support ring plate.

[0008] Preferably, the diameter of each auxiliary pull ring is smaller than the inner diameter of the rigid support plate, the height of the auxiliary pull ring is smaller than the inner height of the rigid support plate, and the outer surface of the pull line is provided with scale lines.

[0009] Preferably, each of the rigid support plates has a through hole at its bottom that mates with the pull line, and a limiting ring plate is fitted on the pull line inside each of the rigid support plates. The inner ring of each limiting ring plate slides and fits against the outer surface of the pull line, and the outer diameter of the limiting ring plate is larger than the diameter of the through hole.

[0010] Preferably, each of the rigid support plates has a symmetrical fixing strap on its inner sidewall, and each of the two fixing straps has a fixing Velcro strap on the opposite side away from the fixing end.

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

[0012] 1. In this utility model, the height of the sponge seal is adjusted by loosening and clamping. While ensuring the integrity of the sponge seal, it solves the problem that existing sponge seals are inconvenient to adjust according to the height of the parts to be sealed. This improves the applicability of the sponge seal, and while being simple and convenient to operate, it also ensures the sealing performance of the sponge seal.

[0013] 2. In this utility model, through the retractable design of the pull line, after the main body of the sponge seal is pulled to the required height, the pull line can be rolled up or folded and fixed inside the fixing strap together with the auxiliary pull ring, so as to avoid affecting the applicability of the sponge seal.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1-4 As shown, this utility model provides an adjustable sponge seal, including a sponge seal body 1. An upper support ring plate 2 and a lower support ring plate 3 are fixed to the upper and lower ends of the sponge seal body 1, respectively. The inner diameters of both the upper and lower support ring plates 2 and 3 are larger than the inner diameter of the sponge seal body 1, and the outer diameters of both are smaller than the outer diameter of the sponge seal body 1. This allows the upper and lower support ring plates 2 and 3 to support the sponge seal body 1, clamping it without affecting its operation. 1. The inner and outer sides are in contact with the structure. Several pull lines 4 are fixed at equal intervals on the top surface of the lower support ring plate 3. The height of each pull line 4 is greater than the sum of the heights of the sponge seal body 1 and the upper support ring plate 2. An auxiliary pull ring 8 is fixed at one end of each pull line 4 extending to the outside of the upper support ring plate 2. Each pull line 4 passes through the sponge seal body 1 and extends to the outside of the upper support ring plate 2. A placement groove 5 is opened on the top of the sponge seal body 1 outside each pull line 4. A rigid support plate 6 is set inside each placement groove 5. Each rigid support plate 6 is fixed to the bottom surface of the upper support ring plate 2.

[0022] The specific settings and functions of this embodiment are described below: The diameter of each auxiliary pull ring 8 is smaller than the inner diameter of the rigid support plate 6, and the height of the auxiliary pull ring 8 is smaller than the internal height of the rigid support plate 6, ensuring that the auxiliary pull ring 8 can be stored inside the rigid support plate 6. Each rigid support plate 6 has a through hole at its bottom that mates with the pull line 4. Each rigid support plate 6 has a limiting ring plate 7 fitted on the pull line 4 inside its interior. The inner ring of each limiting ring plate 7 slides and fits against the outer surface of the pull line 4. Fixing straps 9 are symmetrically fixed on the inner sidewall of the rigid support plate 6. Fixing Velcro 10 is fixed on the opposite side of the two fixing straps 9 away from the fixing end. The outer diameter of the limiting ring plate 7 is larger than the diameter of the through hole, so that the limiting ring plate 7 can abut against the inner bottom surface of the rigid support plate 6. The outer surface of the pull line 4 is provided with scale lines.

[0023] The overall effect of this embodiment is that by adjusting the distance between the upper support ring plate 2 and the lower support ring plate 3, the height of the sponge seal body 1 can be controlled, thereby adapting to parts of different heights to be sealed and improving the applicability of the sponge seal body 1.

[0024] The usage method and working principle of this device are as follows: When the sponge seal body 1 is required, first adjust the height of the sponge seal body 1 according to the height of the part. During adjustment, control the upper support ring plate 2, press the auxiliary pull ring 8, and drive the pull line 4 to move outward, thereby driving the lower support ring plate 3 to move closer to the upper support ring plate 2, thereby adjusting the distance between the upper support ring plate 2 and the lower support ring plate 3. Control the height of the sponge seal body 1 according to the scale line on the surface of the pull line 4. After the adjustment is completed, tie the pull line 4 into a knot so that the knot of the pull line 4 abuts against the limiting ring plate 7, and pushes the limiting ring plate 7 against the inside of the rigid support plate 6. Then, put the excess pull line 4 and the auxiliary pull ring 8 into the inside of the rigid support plate 6. Pass the two fixing straps 9 through the auxiliary pull ring 8 and wrap the excess pull line 4. Then fix the fixing straps 9 to the outside of the auxiliary pull ring 8 and the excess pull line 4 with the fixing Velcro 10, thereby fixing the excess pull line 4 of the auxiliary pull ring 8 inside the rigid support plate 6.
