Referring to fig. 1-3, in order to solve the problem that the rubber ring is difficult to achieve effective balance between the tightness and the compressibility, the present application provides a mounting seal structure, which includes a fastener 100, a fixing sleeve 200 and an elastic seal sleeve 400, wherein the fastener 100 includes a rod 110 and a fixing head 120 fixed at one end of the rod 110, the fastener 100 is inserted into the fixing sleeve 200 through the rod 110, and the fixing head 120 is abutted to one end of the fixing sleeve 200.

The elastic sealing sleeve 400 is sleeved on the outer side of the rod body 110 and abuts against one end of the fixing head 120, which is close to the fixing sleeve 200, and the elastic sealing sleeve 400 is tightly clamped between the outer wall of the rod body 110 and the inner wall of the fixing sleeve 200, and the side wall of the elastic sealing sleeve 400 is provided with a deformation groove 410, so that the compressed elastic sealing sleeve 400 can deform towards the deformation groove 410.

It should be noted that, "the elastic sealing sleeve 400 is tightly clamped between the outer wall of the rod 110 and the inner wall of the fixing sleeve 200" means that: the elastic sealing sleeve 400 is pressed by the rod body 110 and the fixing sleeve 200 at both inner and outer sides thereof, respectively.

During assembly, the elastic sealing sleeve 400 is first sleeved on the outer side of the rod 110 and abuts against the fixing head 120, and then the rod 110 sleeved with the elastic sealing sleeve 400 is inserted into the fixing sleeve 200, and the elastic sealing sleeve 400 is difficult to slide relative to the rod 110 due to the stop effect of the fixing head 120. Because the elastic sealing sleeve 400 is sleeved on the outer side of the rod body 110, the elastic sealing sleeve 400 cannot eccentrically move during assembly, so that the assembly precision of the elastic sealing sleeve 400 is improved, and the tightness of the installation sealing structure is improved.

Moreover, by providing the elastic sealing sleeve 400 tightly clamped between the outer wall of the rod body 110 and the inner wall of the fixed sleeve 200, the elastic sealing sleeve 400 is in a compressed state, and as the elastic sealing sleeve 400 can be elastically deformed, the compressed elastic sealing sleeve 400 has a tendency to expand. In this manner, the elastic sealing kit 400 can effectively seal and block the gap between the fixing sleeve 200 and the rod body 110 by its own expansion, thereby greatly improving the connection sealability between the fastener 100 and the fixing sleeve 200.

Further, by providing the deformation groove 410, the deformed elastic sealing sleeve 400 can be expanded towards the deformation groove 410, that is, the deformation groove 410 can provide sufficient deformation space for the elastic sealing sleeve 400, so as to prevent the elastic sealing sleeve 400 from being difficult to be compressed due to overlarge volume.

In summary, the mounting sealing structure provided by the present application can not only realize effective sealing of the gap between the fastener 100 and the sealing sleeve through the elastic sealing sleeve 400, but also reduce the compression difficulty of the elastic sealing sleeve 400 through the deformation groove 410.

Specifically, the elastic sealing sleeve 400 is a rubber member, a silicone member, or an engineering plastic member. Correspondingly, the fastener 100 and the retaining sleeve 200 are both metal pieces.

It should be noted that the elastic sealing sleeve 400 is made of a soft material and has a certain elastic deformation capability, and of course, in the automotive industry, the elastic sealing sleeve 400 needs to have a certain wear resistance and corrosion resistance.

The deformation grooves 410 may be provided in various ways, and are specifically described below.

In one embodiment, as shown in fig. 2, the deformation groove 410 is formed around the sidewall of the elastic sealing member 400 along the circumferential direction of the elastic sealing member 400.

In this manner, sufficient deformation space can be provided for axial deformation of the elastic sealing sleeve 400.

Further, in an embodiment, as shown in fig. 2, the deformation groove 410 is wound around the outer side of the elastic sealing sleeve 400 along the circumferential direction of the elastic sealing sleeve 400, and the opening of the deformation groove 410 faces the fixing sleeve 200.

In this way, the processing difficulty of the deformation groove 410 is reduced, and the deformation groove 410 can be processed by an integral molding or turning mode.

In another embodiment, the deformation groove 410 is wound around the inner side of the elastic sealing sleeve 400 along the circumferential direction of the elastic sealing sleeve 400, and the opening of the deformation groove 410 faces the rod 110.

In this way, the sealability of the elastic sealing sleeve 400 and the rod body 110 is improved.

However, in other embodiments, the deformation groove 410 may be disposed inside the elastic sealing member 400, that is, the deformation groove 410 is a hollow structure disposed inside the elastic sealing member 400.

In this way, the sealability of both sides of the elastic sealing member 400 can be improved.

In one embodiment, the deformation groove 410 is provided on a sidewall of the elastic sealing member 400 and extends along an axial direction of the elastic sealing member 400.

In this manner, sufficient deformation space can be provided for circumferential deformation of the elastic sealing member 400.

Further, the deformation groove 410 penetrates through the sidewall of the elastic sealing sleeve 400 along the axial direction of the elastic sealing sleeve 400.

In this way, the difficulty of deformation of the elastic sealing sleeve 400 along the circumferential direction is further reduced.

In particular, the deformation groove 410 may be provided inside, outside, or inside the elastic sealing member 400.

In one embodiment, as shown in fig. 3, the deformation groove 410 includes a first groove 411 extending along the circumference of the elastic sealing member 400 and a second groove 412 extending along the axial direction of the elastic sealing member 400, and the first groove 411 and the second groove 412 are disposed to intersect.

In this way, sufficient deformation space can be provided for both circumferential deformation and axial deformation of the elastic sealing sleeve 400.

Similarly, the cross-sectional shape of the deformation groove 410 may be various, specifically, the cross-sectional shape of the deformation groove 410 may be square, arc, trapezoid or triangle, which are not listed herein.

In one embodiment, the compression Q of the elastomeric seal 400 is satisfied, 5% Q50%.

When the compression amount of the elastic sealing member 400 is greater than or equal to 5%, it is possible to avoid the problem that the expansion pressing force applied to the rod body 110 and the fixing sleeve 200 by the elastic sealing member 400 is too small, resulting in a decrease in sealability of the elastic sealing member 400. That is, the compression amount of the elastic sealing sleeve 400 is greater than or equal to 5%, which is beneficial to improving the expansion extrusion force of the elastic sealing sleeve 400, and further improving the tightness of the elastic sealing sleeve 400. When the compression amount of the elastic sealing sleeve 400 is less than or equal to 50%, the excessive compression amount of the elastic sealing sleeve 400 can be avoided, so that the elasticity of the elastic sealing sleeve 400 is reduced and the hardness is increased, and further, the elastic sealing sleeve 400 cannot effectively fit the inner wall of the fixed sleeve 200 and the outer wall of the rod body 110. That is, the compression amount of the elastic sealing sleeve 400 is less than or equal to 50%, which is favorable for ensuring the elastic deformation capability of the elastic sealing sleeve 400, thereby improving the fitting tightness of the elastic sealing sleeve 400 and the inner wall of the fixing sleeve 200, and improving the fitting tightness of the elastic sealing sleeve 400 and the outer wall of the rod body 110.

Further, in one embodiment, 15% Q.ltoreq.20%.

Through a great number of experimental test analyses, when the compression amount of the elastic sealing sleeve 400 is kept between 15% and 20%, the elastic sealing sleeve 400 can effectively balance the expansion extrusion force and the self elastic deformation capability, that is, the elastic sealing sleeve 400 still has better elastic deformation capability on the premise of keeping a certain expansion extrusion force. In this manner, the sealability between the fastener 100 and the fixing sleeve 200 is greatly improved.

Specifically, in one embodiment, the volume of the elastic sealing sleeve 400 is pi (D22-D12) L, the volume of the elastic sealing sleeve 400 is calculated as 3234.583 cubic millimeters, the volume of the gap between the fixing sleeve 200 and the rod 110 with the same length (also L) is pi (D22-D12) L, and the volume of the gap between the fixing sleeve 200 and the rod 110 is calculated as 2695.486 cubic millimeters, so that the compression amount q= (3234.583-2695.486)/3234.583 ≡16.6% of the elastic sealing sleeve 400 is obtained.

In one embodiment, as shown in fig. 1 and 2, one end of the fixing sleeve 200 is provided with a flange 300, and the fixing head 120 abuts against the end of the flange 300 away from the fixing sleeve 200.

In this way, the contact area between the fixing sleeve 200 and the fastener 100 is increased, which is advantageous in improving the assembly stability of the fixing sleeve 200 and the fastener 100.

In one embodiment, as shown in fig. 2, the fastener 100 further includes a tightening head 130, the tightening head 130 is connected to an end of the fixing head 120 away from the rod 110, and the tightening head 130, the fixing head 120 and the rod 110 are integrally formed.

Further, the cross section of the tightening head 130 is hexagonal.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described 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 only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
