Problems solved by technology

Fixing device and carrier are connected by stretching the expansion element so that it is firmly pressed against the edge of the opening of the carrier, but since the sealing element and the joint are directly connected by injection molding, so that the expansion element is stretched Sometimes it will cause the sealing element to bend, resulting in the gap between the sealing element and the carrier, which will affect the sealing effect and structural strength

Embodiment Construction

[0023] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0024] Such as Figure 1 to Figure 8 As shown, it is a structural schematic diagram of the fixing device provided by the present invention. The fixing device includes a connecting piece 10 , an engaging piece 20 matched with the connecting piece 10 , and an end cap 30 arranged on the connecting piece 10 . It is conceivable that the fixing device also includes some other functional modules, such as the carrier connected to the fixing device and the attachment element, etc., which are well known to those skilled in the art, and will not be repeated here.

[0025] The connector 10 includes a body 11, two flanges 12 radially extending from the side wall at one end of the body 11, an embedded portion 13 arranged at the o...

Abstract

The invention relates to a fixing device. The fixing device comprises a connecting piece, a joint piece and an end cap, wherein the connecting piece comprises a body, a flange, an embedded portion and a groove portion, the groove portion comprises a groove and a conical section, the joint piece comprises a cover body, a sealing rib, opening and closing elements and a clamping and locking element, and the cover body is of an arch-shaped structure and is symmetrically arranged by taking a symmetric plane as a symmetry plane. The two opening and closing elements are symmetrically arranged by taking a symmetric plane as a symmetric plane, the symmetric plane of the two opening and closing elements and the symmetric plane of the cover body coincide with each other, the cover body is arched towards the flange by taking a symmetric plane coincide with the symmetric plane of the two opening and closing elements as a standard, and the opening direction of the cover body faces the opening and closing elements, so that the opening and closing elements drive the cover body to be bent in the opening process of the opening and closing elements, the cover body which is originally in an arch shape becomes flat after the opening and closing elements are opened, the cover body and a carrier are attached more tightly, no gap exists, and the sealing performance and the structural strength are improved.

Description

technical field [0001] The invention relates to the technical field of fixing pieces, in particular to a fixing device. Background technique [0002] In the automotive industry, it is necessary to tightly connect the carrier and the attachment element by means of a multi-part fixing device, such as the connection between a body part and a door or panel. Such as the Chinese patent whose patent number is CN200980142850.2. When the fastening device is in the pre-assembled position, the locking element of the coupling part is locked in the first recess region of the connecting part, and the expansion element of the coupling part is in the engagement region. And when the fixing device is in the final assembly position, it is necessary to apply pressure to the upper part along the assembly direction, then the connecting piece moves relative to the engaging piece in the assembly direction after overcoming the holding force of the locking element until the locking element and the c...
