A type of roof rack luggage frame top frame sealing waterproof male and female threaded rod

Abstract

This utility model discloses a waterproof male and female screw rod for sealing the top frame of a car roof rack, relating to the technical field of car roof mounting brackets. It includes a female head with a male head at its bottom, the female and male heads being integrated. A cover is fixedly installed on the side of the male head away from the female head, and a removable sealing ring is installed inside the cover. The intersection of the male head and the sealing ring is a smooth surface. The integrated male and female screw rod, through the cover on the male head surface, allows the special synthetic rubber O-ring seal to be stressed when the screw rod is tightened downwards. The cover restricts the outward movement of the special synthetic rubber O-ring seal, causing it to be squeezed inwards to completely fill the gap between the screw rod and the roof nut, thereby achieving complete sealing of the roof through-hole and increasing the sealing performance between the screw rod and the roof through-hole.

Description

Technical Field

[0001] This utility model relates to the technical field of automobile roof mounting brackets, specifically a sealing and waterproof male and female threaded rod for the top frame of a roof rack luggage frame. Background Technology

[0002] Currently, car manufacturers fix roof racks / frames / roof frames to the headliner. Since the headliner mounting point and the interior trim have a through-hole, nuts are welded inside. A layer of EPDM closed-cell foam is sandwiched between the roof rack / frame / roof frame support and the headliner. Tightening the screw presses down on the EPDM foam to seal the gap between the screw and the nut. However, this method doesn't restrict the EPDM foam from concentrating on the gap between the screw and the nut. Furthermore, the support typically has two fixing points, and simultaneously tightening the screw downwards cannot achieve a complete fit to the headliner. Additionally, there are inherent gaps between the screw and the support, leading to incomplete sealing and allowing rainwater to seep into the interior trim and headliner. To address these issues, a waterproof male and female screw rod for sealing the roof rack / frame / roof frame is proposed. Utility Model Content

[0003] To solve the above problems, the purpose of this utility model is to provide a sealing and waterproof male and female screw rod for the top frame of a roof rack luggage frame.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a sealing and waterproof male and female screw rod for the top frame of a roof rack luggage frame, including a female head, a male head at the bottom of the female head, the female head and the male head being integrated, a cover being fixedly installed on the side of the male head away from the female head, a sealing ring being detachably provided inside the cover, three sets of protrusions being provided at the bottom of the sealing ring, the intersection of the male head and the sealing ring being a smooth surface, and screw threads being provided on the surface of the male head away from the sealing ring.

[0005] Preferably, the sealing ring is made of special synthetic rubber and is an O-ring.

[0006] Preferably, a threaded groove is provided at the center of the top of the female head.

[0007] Preferably, the outer shape of the female head is a hexagonal prism.

[0008] Preferably, the male connector has threads on its surface, and the sealing ring, female connector, and male connector are aligned with the same center line.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] The integrated male and female screws, through the cap on the male head surface, cause the special synthetic rubber O-ring to be stressed when the male and female screws are tightened downwards. The cap restricts the outward movement of the special synthetic rubber O-ring, causing the special synthetic rubber O-ring to be squeezed inwards to completely fill the gap between the screw and the top nut, thereby achieving complete sealing of the top hole and increasing the sealing performance between the screw and the top hole.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-4 As shown, this utility model provides a sealing and waterproof male and female screw rod for the top frame of a roof rack luggage frame, including a female head 101, a male head 201 at the bottom of the female head 101, the female head 101 and the male head 201 are integrated, a cover 202 is fixedly installed on the side of the male head 201 away from the female head 101, a sealing ring 3 is detachably provided inside the cover 202, the bottom of the sealing ring 3 is provided with three sets of bosses 301, the intersection of the male head 201 and the sealing ring 3 is a smooth surface, and the surface of the male head 201 away from the sealing ring 3 is provided with screw threads.

[0019] The sealing ring 3 is made of special synthetic rubber. The sealing ring 3 is O-shaped. The female head 101 has a threaded groove 4 at the center of the top. The female head 101 is hexagonal prism in shape. The male head 201 has threads on its surface. The sealing ring 3, the female head 101 and the male head 201 are on the same center line.

[0020] By employing the above technical solution, the male and female screws are directly screwed onto the roof using a sleeve. When the screws are tightened downwards, the special synthetic rubber sealing ring 3 is subjected to force. The cover 202 installed on the surface of the male head 201 restricts the sealing ring 3 from moving outwards, forcing it to compress inwards to completely fill the gap between the screw and the roof nut, thus completely sealing the roof opening. All the male and female screws are individually fixed to form a complete seal. Finally, the luggage rack / luggage frame / roof frame support is screwed onto the female head 101 of the male and female screws. This completes the sealing and waterproofing of the roof.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
