[0028] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0029] Please refer to Figures 1-6 The present application provides a technical solution: a PET glue box with good waterproofness, comprising a lower box body 1, an upper box body 11 inserted and connected to the upper side of the periphery of the lower box body 1, a threaded sleeve 12 rotatably installed on the periphery of the lower box body 1, the upper box body 11 being threadedly connected with the inner wall of the threaded sleeve 12, a cover plate 13 inserted and connected to the upper end of the upper box body 11, a first sealing ring 16 fixedly installed on the periphery of the upper end of the lower box body 1, the periphery of the first sealing ring 16 being in close contact with the inner wall of the upper box body 11, a second sealing ring 17 fixedly installed in the lower side of the inner cavity of the upper box body 11, and the inner wall of the second sealing ring 17 being in close contact with the periphery of the upper box body 11.

[0030] Working principle: when it is necessary to adjust the volume of the combined inner cavity of the lower box body 1 and the upper box body 11 according to the storage amount of the articles, the threaded sleeve 12 can be rotated on the periphery of the lower box body 1, thereby driving the upper box body 11 to move up and down on the periphery of the lower box body 1 through the threaded connection between the threaded sleeve 12 and the upper box body 11, achieving the effect of adjusting the volume of the combined inner cavity of the lower box body 1 and the upper box body 11. The first sealing ring 16 and the second sealing ring 17 are arranged to seal the upper and lower sides of the connection between the upper box body 11 and the lower box body 1.

[0031] As a further description of the above technical scheme: the first limiting plug rod 14 is fixedly installed at the upper end of the lower box body 1, and the first limiting plug hole 15 is formed at the lower end of the upper box body 11.

[0032] Specifically, through the plug-in connection between the first limiting plug rod 14 and the first limiting plug hole 15, the movement direction of the upper box body 11 can be limited outside the lower box body 1, so that when the threaded sleeve 12 rotates, the upper box body 11 can move up and down.

[0033] As a further description of the above technical scheme: the first limiting plug rod 14 is fixedly installed at the upper end of the lower box body 1, and the first limiting plug hole 15 is formed at the lower end of the upper box body 11.

[0034] Specifically, when the threaded sleeve 12 needs to be rotated, the rotating disc 25 can be rotated outside the limiting seat 24, and under the limitation of the movement direction of the positioning tooth block 22 through the plug-in connection between the second limiting plug rod 211 and the second limiting plug hole 221 in the recess cavity 21, the rotating disc 25 can drive each positioning tooth block 22 to contract into the recess cavity 21 through the sliding connection between the limiting sliding block 222 and the limiting sliding groove 251, so that the positioning tooth block 22 and the positioning tooth groove 231 are separated from each other, thereby the threaded sleeve 12 can be rotated, and the effect of adjusting the volume of the combined inner cavity of the lower box body 1 and the upper box body 11 is achieved.

[0035] When the adjustment is completed, the rotating disc 25 is loosened, and under the action of the restoring deformation of the disc spring 241, the rotating disc 25 can be reversely rotated to drive each positioning tooth block 22 to expand outward to be inserted with the positioning tooth groove 231, thereby achieving the effect of positioning the threaded sleeve 12.

[0036] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
