[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] The following describes some embodiments of the present invention in conjunction with the accompanying drawings to provide a rotary tooth air compressor gearbox.

[0023] Example 1:

[0024] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a rotary gear air compressor gearbox, including a box body 100, a sealing assembly 200, a box cover 300 and a dust cover 400.

[0025] Specifically, a first air storage tank 104 and a groove 103 are provided on the right side of the box body 100, an air inlet pipe 101 is provided at the top of the box body 100, an air outlet pipe 102 is provided at the bottom of the air inlet pipe 101, and a support rod 105 for fixing is provided at the bottom of the box body 100. Both support rods 105 are provided with mounting holes. When in use, the air inlet pipe 101 can suck air into the box body 100, and then a sealed cavity is formed through the two rotating gears of the air compressor, thereby compressing the gas. The compressed gas will be discharged through the air outlet pipe 102 for use.

[0026] Specifically, the sealing assembly 200 is arranged inside the groove 103. The sealing assembly 200 includes a first fixing ring 201 inserted in the groove 103, a plurality of springs 202 arranged on the right side of the first fixing ring 201, a second fixing ring 203 arranged on the right side of the plurality of springs 202, and a sealing strip 204 bonded to the right side of the second fixing ring 203. The cross-sections of the first fixing ring 201, the second fixing ring 203 and the sealing strip 204 are all annular, and the first fixing ring 201, the second fixing ring 203 and the sealing strip 204 are all inserted in the groove 103. When in use, the first fixing ring 201 of the sealing assembly 200 can be aligned with the groove 103 and inserted. During the insertion process, the second fixing ring 203 and the sealing strip 204 are inserted into the groove 103 in sequence. After insertion, when fixing the box cover 300, due to the elasticity of the spring 202, the sealing strip 204 can firmly adhere to the box cover 300, thereby greatly improving the sealing performance.

[0027] Specifically, the box cover 300 is fixedly connected to the box body 100 by bolts, and a threaded seat 301 and a balloon 302 are provided on the right side of the box cover 300, and a second air storage tank 303 corresponding to the first air storage tank 104 is provided on the left side of the box cover 300. A balloon 302 connected to the second air storage tank 303 is arranged on the right side of the box cover 300. During use, when there is an air leakage between the box body 100 and the box cover 300, the gas will enter the first air storage tank 104 and the second air storage tank 303 through the gap between the box body 100 and the box cover 300, and then enter the balloon 302. At this time, due to the high air pressure, the balloon 302 will be inflated, and the state of the balloon 302 can be used to determine whether the gear box is leaking, thereby achieving the effect of visual air leakage detection for easy use.

[0028] Specifically, the dust cover 400 is threadedly connected to the threaded seat 301, and several dust covers 400 correspond to the threaded seats 301 one by one, and several threaded seats 301 are provided with round holes for installing bolts. When in use, the dust cover 400 can seal the bolts inserted into the threaded seat 301 to slow down the aging and corrosion rate of the bolts.

[0029] The working principle and usage process of the present invention are as follows: when there is an air leak between the box body 100 and the box cover 300, the gas will enter the first air storage tank 104 and the second air storage tank 303 through the gap between the box body 100 and the box cover 300, and then enter the balloon 302. At this time, due to the high air pressure, the balloon 302 will be inflated, and the state of the balloon 302 can be checked to determine whether the gear box is leaking, thereby achieving the effect of visual air leakage detection for easy use. At the same time, the first fixing ring 201 of the sealing assembly 200 can be aligned with the groove 103 and inserted. During the insertion process, the second fixing ring 203 and the sealing strip 204 are inserted into the groove 103 in turn. After insertion, when fixing the box cover 300, due to the elasticity of the spring 202, the sealing strip 204 can be firmly attached to the box cover 300, thereby greatly improving the sealing performance.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
