[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please see attached Figure 1-5 , an instrument screw waterproof structure in an embodiment of the utility model includes an instrument 1, the instrument 1 includes an upper shell 11 and a lower shell 13, the upper shell 11 and the lower shell 13 are connected to each other, and a waterproof member 12 is connected between the upper shell 11 and the lower shell 13;

[0027] The waterproof component 12 includes a waterproof gasket 121, which fits the upper shell 11. A plurality of sealing rings 122 are fixedly connected below the waterproof gasket 121. The upper and lower surfaces of the plurality of sealing rings 122 are both arc-shaped, so as to better cooperate with the cavity 112 inside the connecting column 111 and the card slot 132 of the lower shell 13, so as to make them fit more closely, increase the tightness of the connection, ensure the waterproof effect of the sealing ring 122, avoid the occurrence of connection gaps, and improve the stability and reliability of the product waterproofing. The integrated design of the waterproof gasket 121 and the plurality of sealing rings 122 can optimize the installation mode of the instrument screw waterproof structure, effectively avoid the leakage of the O-ring, improve the quickness of its assembly, save assembly time, and improve the product yield rate;

[0028] The bottom of the upper shell 11 is fixedly connected with a plurality of connecting columns 111 , and the lower shell 13 is fixed with a plurality of mounting columns 131 , which correspond to the connecting columns 111 , and the waterproof gasket 121 is connected to the mounting columns 131 and the connecting columns 111 through the sealing ring 122 .

[0029] The lower shell 13 is provided with a plurality of through holes 134, and the mounting column 131 is fixedly connected in the through hole 134. A slot 132 is provided on the side of the mounting column 131 close to the upper shell 11, and the sealing ring 122 is sleeved on the bottom of the slot 132. During installation, the slot 132 can further limit the sealing ring 122, and at the same time, the sealing ring 122 can fill the connection gap, thereby improving the tightness and stability of the connection.
