Example 1:

referring to fig. 1-6, the present embodiment provides a waterproof tie comprising a tie body 1, a seal assembly and an elastic shroud 3.

Wherein, the one end of the belt body 1 is the locking piece 11, has seted up lockhole 111 on the locking piece 11, and the other end and the lockhole 111 cooperation of the belt body 1, the specific theory of operation of the belt body 1 of this embodiment and further specific structure are the conventional structure setting of ribbon, are prior art, and this embodiment is not repeated.

The seal assembly comprises a sealing plate 22 and a plug 21, and the plug 21 is fixedly arranged on the upper surface of the sealing plate 22. The plug 21 is mounted in a mounting hole in the sheet metal.

The elastic shield 3 is provided with a sealing opening 31. In this embodiment, the shape of the elastic shield 3 is substantially similar to a truncated cone, and the sealing opening 31 is located at the bottom wall of the elastic shield 3.

Wherein the locking piece 11 is fixed to the lower surface of the sealing plate 22 such that the band body 1 and the sealing assembly form an integral structure. By mounting the sealing plate 22 to the sealing port 31 such that the plug 21 passes through the sealing port 31, the front end of the plug 21 is finally exposed outside the elastic shield 3, and the rest is located inside the elastic shield 3. The part of the plug 21 outside the elastic shield 3 can be installed in the installation hole on the metal plate, so that the opening edge of the elastic shield 3 can be pressed on the metal plate to play a waterproof role on the installation hole on the metal plate. The sealing plate 22 can seal the sealing opening 31, so that a relatively airtight space is formed between the elastic shield 3 and the metal plate, and the waterproof effect is achieved.

Unlike the prior art, in this embodiment, the elastic shield 3 is made of a soft material with a certain degree of deformability, such as TPE (thermoplastic elastomer), so that the edge profile of the sealing opening 31 can be slightly changed according to the specific shape of the edge of the sealing plate 22 during the process of assembling the sealing plate 22 to the sealing opening 31, so that the gap between the edge profile of the sealing plate 22 and the edge profile of the sealing plate 22 is reduced or eliminated, so that the sealing performance between the sealing plate 22 and the edge of the sealing opening 31 is improved, and finally, the edge of the sealing opening 31 and the edge of the sealing plate 22 are elastically connected. The above elastic connection manner avoids further using glue between the sealing plate 22 and the edge of the sealing opening 31, and the corresponding surface and opening edge of the elastic shield 3 will not reduce the tightness between the metal plate due to the protrusion of the glue.

In addition, the elastic shield 3 can also improve the shock-resistant buffer capacity through deformation, so that the shock-resistant buffer is suitable for jolting in the running process of an automobile, and the damage condition of the elastic shield 3 is reduced, so that good sealing performance is kept between the sealing plate 22 and the edge of the sealing opening 31 for a long time.

In order to prevent the seal plate 22 from being detached from the seal port 31, the present embodiment provides one of specific structures of the seal plate 22.

Wherein the sealing plate 22 comprises a first plate 221, a second plate 222 and a connecting post 223. The shapes of the first plate 221 and the second plate 222 are substantially consistent, the first plate 221 and the second plate 222 are approximately in a disc shape or an elliptic sheet shape, the first plate 221 and the second plate 222 are oppositely arranged, two ends of the connecting column 223 are respectively and fixedly connected in the middle of the first plate 221 and the middle of the second plate 222, and a certain gap is reserved between the first plate 221 and the second plate 222 through the connecting column 223 while the first plate 221 and the second plate 222 are connected through the connecting column 223, so that a first clamping tooth 2211 can be arranged on one surface of the first plate 221 facing the second plate 222, the first clamping tooth 2211 is accommodated in the gap between the first plate 221 and the second plate 222, and particularly, a certain gap is reserved between the first clamping tooth 2211 and the second plate 222. The inner wall of the elastic shield 3 is provided with a second latch 32, and the second latch 32 can be engaged with the first latch 2211 by using a gap between the first latch 2211 and the second plate 222, so as to avoid the sealing plate 22 from rotating at the sealing opening 31. In addition, the second latch 32 and the elastic shield 3 are integrally formed, so that the elastic shield 3 and the second latch 32 are made of the same material, and the second latch 32 can be abutted against the second plate 222 after being snapped onto the first latch 2211, thereby preventing the sealing plate 22 from moving axially at the sealing opening 31.

Preferably, the first latch 2211 is positioned at the edge of the first plate body 221, so that after being engaged with the second latch 32, the contact area between the sealing plate 22 and the edge of the sealing port 31 can be increased, thereby improving the sealing degree. In addition, since the connection post 223 is positioned between the first plate 221 and the second plate 222, the edge of the first plate 221 may provide enough space for the first latch 2211.

In order to avoid radial movement of the sealing plate 22 at the sealing opening 31, in this embodiment, a plurality of limiting ribs 33 are provided on the inner wall of the elastic shield 3, the limiting ribs 33 encircle the connecting column 223, and the limiting ribs 33 play a radial limiting role on the connecting column 223, so as to radially limit the whole sealing plate 22. Certain things can be left between the ends of the adjacent limiting ribs 33, so that the second latch 32 is avoided.

In order to be able to further improve the connection stability and the connection strength of the sealing plate 22 at the sealing port 31, the sealing plate 22 further includes a connection block 224. The connection block 224 is located between the first plate 221 and the second plate 222 while maintaining a fixed connection relationship with the first plate 221 and the second plate 222. The connecting post 223 and the connecting block 224 are enclosed to form a limiting hole 2241, and the limiting rib 33 passes through the limiting hole 2241, so that the difficulty of separating the limiting rib 33 from the sealing plate 22 is increased.

Because spacing rib 33 and the inner wall fixed connection of elastic shield 3, in order to make spacing rib 33 pass spacing hole 2241 smoothly, spacing rib 33 is provided with on the outer wall of elastic shield 3 inner wall department and dodges breach 331, dodges breach 331 promptly and is located between spacing rib 33 and the elastic shield 3 inner wall, thereby connecting block 224 is located and dodges breach 331 department and obtain dodging.

In this embodiment, the second plate 222 fills and covers the sealing opening 31, and the connecting block 224 is located at the edges of the first plate 221 and the second plate 222 to be attached to the inner wall of the elastic shield 3, so as to increase the contact area between the sealing plate 22 and the edge of the sealing opening 31, thereby improving the tightness of the edge of the sealing opening 31.

Based on the above structure, the seal assembly and the elastic shield 3 cannot be assembled in a conventional clamping manner, so that the seal assembly and the elastic shield 3 are obtained by a double-color injection molding process, and the seal assembly and the belt body 1 are made of the same material, and the material is different from that of the elastic shield 3. For example, the materials of the belt body 1 and the sealing component in this embodiment are PA66.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
