[0023] As shown in the attached Figure 1 to the attached Figure 6 figures

[0024] Embodiment 1: The present utility model provides a waterproof equipment distribution box, which includes a box body assembly 1. The box body assembly 1 includes a distribution box body 101, a sealing gasket 102 and an enclosing door 103. The enclosing door 103 is inserted into the side surface of the distribution box body 101, and the sealing gasket 102 is inserted into the inside of the distribution box body 101, and both sides of the sealing gasket 102 are respectively abutted and squeezed by the distribution box body 101 and the enclosing door 103. It further includes a sealing assembly 2. The sealing assembly 2 includes a control panel 201, a force application block 202, a positioning worm gear 203, an operating worm 204 and a transmission block 205. The control panel 201 is rotatably connected to the inside of the enclosing door 103, and the force application block 202 is inserted into the inside of the enclosing door 103. The positioning worm gear 203 is rotatably connected to the outside of the enclosing door 103, and the operating worm 204 is rotatably connected to the outside of the enclosing door 103. There is a transmission connection between the positioning worm gear 203 and the operating worm 204, and the transmission block 205 is inserted into the inside of the rotating shaft of the positioning worm gear 203

[0025] In the embodiment of the present disclosure, a locking groove 1011 is provided inside the distribution box body 101, and the force application block 202 is inserted into the locking groove 1011. The shapes of the outer cross-sections of the locking groove 1011 and the force application block 202 are both right-angled triangles, and the hypotenuses of the groove body of the locking groove 1011 and the block body of the force application block 202 are both designed to face the outside of the distribution box body 101. During use, the closing door 103 is installed and removed on the distribution box body 101 through the sealing assembly 2. Insert the closing door 103 into the distribution box body 101, and rotate the positioning worm gear 203 in the locking direction by operating the worm 204. When the positioning worm gear 203 is rotated in the locking direction by operating the worm 204, the positioning worm gear 203 can drive the transmission block 205 to rotate synchronously. Under the action of the transmission top spring 2051, the hypotenuses of the teeth between the transmission block 205 and the transmission tooth ring 2052 of the control disk 201 can be mutually squeezed and touched, thereby driving the control disk 201 to rotate synchronously. A control rod 2021 is provided on the side surface of the force application block 202, and a control groove 2011 is provided inside the control disk 201. The control rod 2021 is inserted into the control groove 2011. When the control disk 201 rotates, the control groove 2011 can drive the force application block 202 to move outwards through the control rod 2021 and extend out of the closing door 103. After the force application block 202 extends out of the closing door 103, it will be inserted into the locking groove 1011. As the force application block 202 gradually extends out of the closing door 103, the hypotenuses between the force application block 202 and the locking groove 1011 can be mutually squeezed and abutted, so that the closing door 103 is locked inside the closing door 103, and the locking pressure can act on the sealing gasket 102 through the closing door 103, thereby squeezing and deforming the sealing gasket 102 to realize the function of sealing the connection part between the closing door 103 and the distribution box body 101. The use is stable, the sealing gasket 102 is uniformly stressed, and the sealing effect is excellent. When it is necessary to disassemble the closing door 103, just operate the worm 204 to drive the positioning worm gear 203 to rotate in the loosening direction. At this time, the force application block 202 will move and hide inside the closing door 103, thereby releasing the locking force between it and the distribution box body 101. Until the force application block 202 is completely hidden inside the closing door 103, the closing door 103 can be removed from the side of the distribution box body 101, which is convenient for subsequent maintenance and other operations, and the use is flexible and convenient.

[0026] In the embodiment of the present disclosure, the cross-sectional shape of the block body of the transmission block 205 is a regular polygon, and this design makes the rotation states of the transmission block 205 and the positioning worm gear 203 always synchronous.

[0027] In the embodiment of the present disclosure, a transmission top spring 2051 is provided inside the transmission block 205, and both ends of the transmission top spring 2051 abut against the inside of the transmission block 205 and the inside of the positioning worm gear 203 respectively. Transmission tooth rings 2052 are provided on the opposite sides of the transmission block 205 and the control disk 201. Under the action of the transmission top spring 2051, the teeth between the two transmission tooth rings 2052 are inserted into each other. The cross-sectional shape of a single tooth of the transmission tooth ring 2052 is a right triangle. When the positioning worm gear 203 rotates in the locking direction, the hypotenuses of the teeth of the two transmission tooth rings 2052 are squeezed and transmitted to each other. During use, the sealing assembly 2 also has the function of limiting the locking force, which can effectively avoid the phenomenon that the sealing gasket 102 is over-squeezed and damaged, resulting in the failure of the sealing function. The use is stable. When the locking force is less than the set force, at this time, the locking pressure is less than the force maintained by the transmission top spring 2051 for the hypotenuse extrusion transmission between the two transmission tooth rings 2052. Therefore, at this time, the transmission block 205 can stably drive the control disk 201 to rotate to achieve the locking action. When the locking force is greater than the set force, at this time, the locking pressure is greater than the force maintained by the transmission top spring 2051 for the hypotenuse extrusion transmission between the two transmission tooth rings 2052. At this time, under the action of the hypotenuse contact of the two transmission tooth rings 2052, the transmission block 205 will automatically move into the inner part of the rotating shaft of the positioning worm gear 203 to avoid its own rotation action, and will not continue to drive the control disk 201 to rotate, thus realizing the function of limiting the locking force.

[0028] The specific usage method and function of this embodiment:

[0029] In the present utility model, the closing door 103 is installed and removed on the power distribution box body 101 through the sealing assembly 2. The closing door 103 is inserted into the interior of the power distribution box body 101, and by operating the worm 204, the positioning worm wheel 203 can be driven to rotate in the locking direction. When the positioning worm wheel 203 is driven to rotate in the locking direction by operating the worm 204, the positioning worm wheel 203 can drive the transmission block 205 to rotate synchronously. Under the action of the transmission top spring 2051, the tooth hypotenuses between the transmission block 205 and the transmission tooth ring 2052 of the control disk 201 can be mutually extruded and touched, thereby driving the control disk 201 to rotate synchronously. When the control disk 201 rotates, the control groove 2011 can drive the force application block 202 to move outwards through the control rod 2021 and extend out of the interior of the closing door 103. And after the force application block 202 extends out of the interior of the closing door 103, it will be inserted into the locking groove 1011. As the force application block 202 gradually extends out of the closing door 103, the hypotenuses between the force application block 202 and the locking groove 1011 can be mutually extruded and abutted, so that the closing door 103 is locked inside the power distribution box body 101, and the locking pressure can act on the sealing gasket 102 through the closing door 103, thereby extruding and deforming the sealing gasket 102 to realize the function of sealing the connection part between the closing door 103 and the power distribution box body 101. It is stable in use, the sealing gasket 102 is uniformly stressed, and the sealing effect is excellent. Moreover, the sealing assembly 2 also has the function of limiting the locking force, which can effectively avoid the phenomenon that the sealing gasket 102 is over-extruded and damaged due to excessive locking force, resulting in the failure of the sealing function. It is stable in use. When the locking force is less than the set force, at this time the locking pressure is less than the force for maintaining the hypotenuse extrusion transmission between the two transmission tooth rings 2052 by the transmission top spring 2051. Therefore, at this time, the transmission block 205 can stably drive the control disk 201 to rotate to realize the locking action. When the locking force is greater than the set force, at this time the locking pressure is greater than the force for maintaining the hypotenuse extrusion transmission between the two transmission tooth rings 2052 by the transmission top spring 2051. At this time, under the action of the hypotenuse abutment of the two transmission tooth rings 2052, the transmission block 205 will automatically move into the interior of the rotating shaft of the positioning worm wheel 203 to avoid its own rotation action, and will not continue to drive the control disk 201 to rotate, thereby realizing the function of limiting the locking force. When it is necessary to disassemble the closing door 103, only need to operate the worm 204 to drive the positioning worm wheel 203 to rotate in the loosening direction. At this time, the force application block 202 will move into the interior of the closing door 103 and hide, thereby releasing the locking force between it and the power distribution box body 101. Until the force application block 202 is completely hidden in the interior of the closing door 103, the closing door 103 can be removed from the side of the power distribution box body 101, which is convenient for subsequent maintenance and other operations.

[0030] In another embodiment, it can be used by assembling drive top springs 2051 of different specifications. The elastic forces of drive top springs 2051 of different specifications are also different. Therefore, assembling drive top springs 2051 of different specifications can realize the function of adjusting the maximum locking force, and can be used on box assemblies 1 of different types and specifications, improving the adaptability of the device.
