[0024] This application provides a EPDM sealing strip that effectively solves the technical problem that during installation, the positioning strip 2 is inserted into the positioning groove of the installation position, and the sealing strip is fixed inside the positioning groove by the shape of the positioning strip 2. When the positioning strip 2 undergoes slight deformation due to external environmental factors (such as temperature changes, mechanical vibration, etc.), the connection stability between the positioning strip 2 and the positioning groove is reduced, thereby affecting the sealing performance of the sealing strip. Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this embodiment effectively solves the technical problem that during the installation of the sealing strip, the positioning strip 2 is inserted into the positioning groove of the installation position, and the sealing strip is fixed inside the positioning groove by the shape of the positioning strip 2. When the positioning strip 2 undergoes slight deformation due to external environmental factors (such as temperature changes, mechanical vibration, etc.), the connection stability between the positioning strip 2 and the positioning groove decreases, thereby affecting the sealing performance of the sealing strip. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a EPDM sealing strip, including a sealing strip body 1, a positioning clip 2 fixedly installed on the outside of the sealing strip body 1, a cavity 3 opened on the outside of the positioning clip 2, and a clamping mechanism for connecting with the positioning groove on the outside of the sealing strip body 1. The clamping mechanism includes an opening 4, a clamping plate 5, an opening 6, a clamping plate 7, and springs 8. The opening 4 is opened on the outside of the sealing strip body 1 and communicates with the inside of the cavity 3. The clamping plate 5 is slidably connected to the inside of the opening 4. The opening 6 is opened on the side of the sealing strip body 1 near the opening 4 and communicates with the inside of the cavity 3. The clamping plate 7 is slidably connected to the inside of the opening 6. There are two springs 8, which are arranged on the side of the clamping plate 7 near the clamping plate 5 and are used to support the clamping plate 7 and the clamping plate 5. The two springs 8 are located inside the cavity 3.

[0027] A rubber block 10 is provided on the outside of the clamping plate 2 7. The rubber block 10 is slidably connected to the inside of the cavity 3. A placement groove 9 is provided on the side of the rubber block 10 near the clamping plate 1 5. Two springs 8 are fixedly connected to the inside of the placement groove 9. The clamping plate 1 5 is slidably connected to the inside of the placement groove 9.

[0028] Both ends of the clamping plate 5 are fixedly installed with support shafts 11, and springs 8 are movably sleeved on the outside of the support shafts 11.

[0029] Two clamping blocks 12 are fixedly installed at both ends of the clamping plate 2 7. The two ends of the rubber block 10 are provided with slots 13. The two slots 13 are connected to the interior of the placement slot 9. The clamping blocks 12 are engaged inside the slots 13.

[0030] Each card block 12 has a threaded hole 14 on its exterior, and each threaded hole 14 has a bolt 15 threadedly connected inside, with the bolt 15 located inside the placement groove 9.

[0031] Opening 4 and opening 6: These are the moving channels for clamping plate 5 and clamping plate 7, respectively, so that the clamping plates can move telescopically between the sealing strip body 1 and the cavity 3 of the positioning strip 2 to achieve the clamping and releasing function of the positioning groove.

[0032] Clamping plate 1 5 and clamping plate 2 7: Both clamping plate 1 5 and clamping plate 2 7 are made of rubber and are in contact with the inner wall of the positioning groove. Through the elastic force of spring 8, they are tightly clamped inside the positioning groove, which enhances the connection and tightness between the sealing strip and the installation position, prevents the sealing strip from falling off, and further improves the stability of the sealing strip after installation.

[0033] Spring 8: Provides elastic restoring force. When the clamping plate is pushed to compress the spring 8, the spring 8 can push the two clamping plates to make close contact with the inner wall of the positioning groove when releasing the external force, ensuring the clamping effect. At the same time, it can adapt to positioning grooves of different sizes to a certain extent, increasing the applicability of the rubber strip.

[0034] Rubber block 10 and placement groove 9: Rubber block 10 provides installation space for spring 8 and clamping plate 5, and placement groove 9 provides sliding space for spring 8 and clamping plate 5, so that spring 8 can be compressed and extended in it, while restricting the direction of movement of clamping plate 5 and ensuring the stability of its movement.

[0035] Support shaft 11: Fixed at both ends of clamping plate 1 5, with spring 8 movably sleeved on its outside, serving to guide the extension and retraction direction of spring 8 and prevent spring 8 from twisting, so that the elastic force of spring 8 can act more effectively on clamping plate 1 5 and clamping plate 2 7.

[0036] The clamping block 12 and the slot 13: The clamping block 12 is made of rubber and is snapped into the slot 13, which realizes the detachable connection between the clamping plate 7 and the rubber block 10, making it convenient for installation, maintenance and replacement of parts.

[0037] Bolt 15: It engages with the threaded hole 14 on the outside of the clamping block 12 to fix the clamping block 12 in the clamping groove 13, further enhancing the reliability of the connection between the clamping plate 2 7 and the rubber block 10 and preventing the two from separating during use.

[0038] Working principle:

[0039] First, insert clamping plate 2 7 and rubber block 10 into the cavity 3, then push rubber block 10 to move clamping plate 2 7 through opening 2 6 to the outside of cavity 3. At this time, clamping plate 1 5 enters the cavity 3 through opening 1 4, and then push clamping plate 1 5 to enter the placement groove 9. At this time, spring 8 is movably sleeved on the outside of support shaft 11.

[0040] In the second step, before the positioning clip 2 needs to be inserted into the positioning groove of the installation position, push the clamping plate 5 and the clamping plate 7 so that they enter the interior of the opening 4 and the opening 6 respectively. Since the clamping plate 5 has a support shaft 11 fixed at both ends, the spring 8 is movably sleeved on the outside of the support shaft 11. The spring 8 will be compressed or extended as the clamping plate 5 moves. At the same time, the support shaft 11 ensures the stability of the extension and contraction direction of the spring 8 and avoids the spring 8 from twisting and deforming. At this time, one end of the clamping plate 5 pushes the spring 8 to compress the spring 8. Then, the positioning clip 2 is inserted into the interior of the positioning groove. Under the action of the spring 8, the clamping plate 5 and the clamping plate 7 move to the outside of the opening 4 and the opening 6 and contact the interior of the positioning groove.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
