Problems solved by technology
[0004] However, by the patent image 3 It can be understood that: 1. The waterproof component does not have a positioning point, so that the construction personnel may need to use measuring tools and instruments to assist in measuring the depth of the waterproof component during assembly. Such joints increase the difficulty of assembly; 2. Due to the depth is not fixed, the patent image 3 3. The positioning hole of the patented waterproof component is always perforated, and such a structure cannot achieve the fine-tuning function of the shelf At the same time, the construction personnel must carefully lock the screws during assembly, otherwise there will be inaccurate problems in assembly

Embodiment Construction
[0028] see Figure 1 to Figure 4 The waterproof structure that the pipe material of the present invention joins, in figure 1 Shown is the structure of the roof rack 100 , which can also be used in bicycle carrying racks (not shown in the figure).
[0029] Such as Figure 2 to Figure 4 As shown, the roof rack 100 is a structure designed in half, and the roof rack 100 is manufactured by bending a metal pipe, so a male joint end 10 and a female joint end 20 are formed at the connecting portion. end 10 is smaller in diameter than the female mating end 20, as Figure 4 As shown, the male joint end 10 and the female joint end 20 are respectively provided with a joint hole 11, 21, and the wall surface of the joint hole 11, 21 is provided with sections of internal thread 111, 211, and the male joint end 10 is combined during assembly. Inside the female joint end 20 , the joint components such as joint bolt S are used to lock and joint the two.

The invention relates to a waterproof structure for pipe connection. The waterproof structure comprises a male joint end and a female joint end, the diameter of the male joint end is smaller than thediameter of the female joint end, the waterproof structure is of a rod-shaped structure and can define a first side, a second side and a connecting part, the first side is at least provided with a first water stop part, the second side is provided with a second water stop part, the first side and the second side are connected into a whole through the connecting part, a positioning through hole isformed in the connecting part, joint holes corresponding to each other are formed in the male joint end and the female joint end of the pipe, after at least one joint bolt penetrates into the joint holes, the bottom of the joint bolt is exactly assembled into the positioning through hole, therefore, the male joint end and the female joint end are jointed, and the effect of two-side waterproof is achieved.
Description
technical field [0001] The present invention relates to a connection structure, in particular to a waterproof structure in which pipes are connected with each other easily and with good waterproof effect. Background technique [0002] Such as figure 1 Shown is the storage rack on the roof of the vehicle. Most of this type of storage rack is formed by bending metal pipes. Generally speaking, the storage rack is constructed in two halves. When assembled on the roof, the two parts are connected by joint components such as screws. The combination of the former can reduce the volume of the package on the one hand, and on the other hand, it also provides the flexibility of assembly, making the assembly of the shelf more convenient. [0003] Because the storage rack is formed by metal pipes, the waterproofness of the assembly position must be considered. For example, US Patent No. US6425508 teaches that a waterproof component is assembled inside the male joint end, and the male jo...
