Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] See Figure 1-4 The present invention provides a waterproof rubber plug sealing structure 100, which includes a middle frame housing 10 and a waterproof rubber plug 20 installed on the middle frame housing 10. The middle frame housing 10 is provided with a mounting groove 11 for installing the waterproof rubber plug 20. The waterproof rubber plug 20 includes a foldable sealing part 21 and a connecting part 22 elastically connected to the bottom of the sealing part 21. The waterproof rubber plug 20 is installed in the mounting groove 11 through the connecting part 22. The mounting groove 11 is provided with a mounting structure that cooperates with the connecting part 22. By utilizing the foldable sealing part 21 of the waterproof rubber plug 20, the sealing part 21 of the waterproof rubber plug 20 can be stored without affecting the waterproof function of the unfolded side. It can also meet the waterproofing problem of the interface structure on multiple parts of the middle frame housing 10, and effectively reduce the number of rubber plugs required, thus reducing production costs. Furthermore, by using the mounting structure to install the waterproof rubber plug 20 into the mounting groove 11 of the middle frame housing 10 through the connecting part 22, the stability of the waterproof rubber plug 20 installed on the middle frame housing 10 can be effectively guaranteed, and the occurrence of the waterproof rubber plug 20 falling off the middle frame housing 10 can be avoided.

[0019] like Figure 2 As shown, the sealing part 21 of the waterproof rubber plug includes a first sealing plate 211 and a second sealing plate 212 that are movably connected. Both the first sealing plate 211 and the second sealing plate 212 can meet the requirements for sealing and waterproofing the interface within the mounting groove 11 of the middle frame housing 10. In addition, the first sealing plate 211 is provided with a folding boss 2111, and the second sealing plate 212 is provided with a folding groove 2121 for the folding boss 2111 to be inserted. When the interface at the first sealing plate 211 or the second sealing plate 212 is needed, the first sealing plate 211 can be folded and stored on the second sealing plate 212, or the second sealing plate 212 can be folded and stored on the first sealing plate 211, so that the folding boss 2111 is inserted into the folding groove 2121, which can meet the storage requirements of the first sealing plate 211 and the second sealing plate 212 of the waterproof rubber plug, without affecting the sealing and waterproofing function of the folded sealing plate for the interface.

[0020] like Figure 3 As shown, the mounting groove 11 includes a snap-fit ​​portion 111 that engages with the second sealing piece 212 and a mounting portion 112 for mounting in conjunction with the connecting portion 22 of the waterproof rubber plug 20. The mounting structure includes a plurality of positioning posts 1121 disposed within the mounting portion 112 and mounting holes 1122 disposed between the positioning posts 1121. The bottom of the connecting portion 22 is provided with a connecting boss 221 that engages with the positioning posts 1121 and the mounting holes 1122. When the waterproof rubber plug 20 is installed in the mounting groove 11 of the middle frame housing 10, the connecting portion 22, which is elastically connected to the bottom of the sealing portion 21, is first bent so that the connecting boss 221 is flush with the mounting portion 112 of the mounting groove 11 in the horizontal direction. Subsequently, the connecting boss 221 is provided with a plurality of positioning holes 2211 for embedding into the positioning posts 1121, and the plurality of positioning holes 2211 are provided with clearance holes 2212 for avoiding the mounting holes 1122. By embedding the positioning post 1121 into the positioning hole 2211 of the connecting boss 221, the operation of positioning and installing the connecting part 22 of the waterproof rubber plug 20 into the mounting groove 11 can be completed.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the mounting structure also includes a fixing plate 30, which has a fixing hole 31 for a locking member to pass through. The locking member passes through the fixing hole 31 and is locked in the mounting hole 1122, so that the fixing plate 30 is pressed against the top of the connecting boss 221. After the positioning pin 1121 in the mounting groove 11 is inserted into the positioning hole 2211 of the connecting boss 221, the fixing plate 30 is pressed against the top of the connecting boss 221, and the fixing members such as bolts, studs and pins pass through the fixing hole 31 on the fixing plate 30 and are locked in the mounting hole 1122 of the mounting groove 11. This effectively ensures the stability of the fixing plate 30 locked against the top of the connecting boss 221, thereby effectively improving the stability of the connecting boss 221 of the waterproof rubber plug 20 installed in the mounting groove 11.

[0022] like Figure 2 and Figure 3As shown, the mounting portion 112 of the mounting groove 11 also has a mounting boss 1123, and the middle part of the connecting portion 22 has a hollow structure and forms a connecting groove 222 for the mounting boss 1123 to be inserted. By inserting the mounting boss 1123 into the connecting groove 222 of the connecting portion 22, the positioning accuracy and installation stability of the connecting portion 22 of the waterproof plug in the mounting groove 11 can be further improved. In addition, positioning protrusions 32 are provided on both sides of the fixing piece 30, and the mounting portion 112 of the mounting groove 111 has a positioning groove 1124 for the positioning protrusions 32 to be inserted. By inserting the positioning protrusions 32 of the fixing piece 30 into the positioning grooves 1124 of the mounting portion 112 of the mounting groove 111, the positioning accuracy of the fixing piece 30 in the mounting portion 112 can be effectively improved, and the stability of the fixing piece 30 pressed and installed on the top of the connecting boss 221 can be further improved.

[0023] like Figure 2 and Figure 4 As shown, the bottom of the first sealing piece 211 and the second sealing piece 212 of the waterproof rubber plug 20 are provided with a sealing part 23 for sealing the interface. In the embodiment provided by this utility model, the mounting groove 11 of the middle frame housing 10 is also provided with a sealing groove and a sealing boss that cooperate with the sealing part 23, thereby effectively ensuring the sealing performance of the sealing part 23 of the first sealing piece 211 and the second sealing piece 212 when they are fastened and installed in the mounting groove 11 of the middle frame housing 10, thereby further ensuring the waterproof sealing function of the first sealing piece 211 and the second sealing piece 212 of the waterproof rubber plug 20.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
