Specific implementation mode

[0031] As Figures 1 - 4As shown in the figure, an explosion-proof distribution box with an auxiliary installation structure includes an explosion-proof distribution box body 10. A waterproof cover 11 is fixedly connected to the front side of the explosion-proof distribution box body 10 through a set of bolts. An auxiliary installation component is arranged on the rear side of the explosion-proof distribution box body 10. The auxiliary installation component includes a U-shaped frame 12. Convex blocks 13 are fixedly connected to the left and right sides inside the U-shaped frame 12 respectively. An installation mechanism 20 is arranged on the rear side of the U-shaped frame 12. The installation mechanism 20 includes a back plate 201. A T-shaped block 202 is fixedly connected to the front side of the back plate 201. The T-shaped block 202 includes a horizontal block and a vertical block connected vertically. A first guiding groove 203 adapted to the convex block 13 is opened on each of the left and right sides of the vertical block.

[0032] Specifically, a set of positioning grooves 14 are opened inside the convex block 13. A positioning bolt 15 is threadedly connected to the bottom of the U-shaped frame 12. A first sliding groove 204 is opened inside the vertical block. A slider 205 is arranged inside the first sliding groove 204. A first spring 208 is fixedly connected to the top of the slider 205. The top of the first spring 208 is fixedly connected to the first sliding groove 204. A through groove 211 is opened at the bottom of the first sliding groove 204. A set of uniformly arranged through grooves are opened on each of the left and right sides of the vertical block. The inner side of the through groove communicates with the first sliding groove 204, and a positioning plug 209 is slidably connected inside the through groove 211. A connecting rod 210 is hinged to the inner side of the positioning plug 209 through a hinge. The inner side of the connecting rod 210 is hinged to the slider 205 through a hinge.

[0033] Preferably, a second guiding groove 206 is opened on the top of the slider 205. A first guiding block 207 is slidably connected inside the second guiding groove 206. The top of the first guiding block 207 is fixedly connected to the first sliding groove 204. Thus, the guiding effect on the movement of the slider 205 is achieved.

[0034] Before installing the explosion-proof distribution box body 10, it is necessary to first install the back plate 201 on the appropriate wall surface through fasteners such as bolts. Then, the operator pushes the explosion-proof distribution box body 10 to insert the inner hollow part of the U-shaped frame 12 into the vertical block, and makes the convex block 13 insert into the first guiding groove 203. Then, the explosion-proof distribution box body 10 is pushed upward until the explosion-proof distribution box body 10 moves to the appropriate position. Then, the positioning bolt 15 is rotated to make the positioning bolt 15 move upward to contact the bottom of the slider 205 through the through groove 211 and drive the slider 205 to move upward. Thus, the positioning plug 209 is driven by the connecting rod 210 to move outward along the through groove 211 and insert into the corresponding positioning groove 14, achieving the effect of installing the explosion-proof distribution box body 10 on the back plate 201. And during the installation, through the guiding and positioning of the auxiliary installation structure, the effect of quick and convenient installation of the explosion-proof distribution box body 10 is achieved.

[0035] During the above installation process, since the explosion-proof distribution box body 10 is relatively heavy, it is necessary to lift it by multiple operators to complete the installation action, which affects the installation efficiency; therefore, an auxiliary mechanism 30 is proposed.

[0036] Refer to Figures 3 - 6 , the auxiliary mechanism 30 includes a pair of fixed boxes 301 that are respectively and fixedly connected to the bottom of the T-shaped block 202 and are symmetric left and right. A set of labor-saving springs 302 are fixedly connected to the bottom of the fixed box 301. A cleaning mechanism 40 is arranged at the bottom of the labor-saving spring 302. The cleaning mechanism 40 includes a cleaning box 401 connected to the labor-saving spring 302. A connecting block one 303 is fixedly connected to the bottom of the cleaning box 401. A pressing groove 305 is formed in the rear side inside the connecting block one 303. A pressing spring 306 is fixedly connected to the inner side of the pressing groove 305. A fixed point block one 307 that is slidably connected to the pressing groove 305 is fixedly connected to the rear side of the pressing spring 306; a notch one 308 is formed in the front surface of the back plate 201, and the fixed point block one 307 is inserted into the notch one 308.

[0037] Further, refer to Figure 6 , a translation groove 309 is formed in the right side of the connecting block one 303. The translation groove 309 communicates with the pressing groove 305. A fixed frame 310 is fixedly connected to the inside of the translation groove 309. A pair of connecting springs 311 arranged front and back are fixedly connected to the right side of the fixed frame 310. A connecting block two 312 that is slidably connected to the translation groove 309 is fixedly connected to the right side of the connecting spring 311; a turning rod 315 is hinged to the inside of the fixed frame 310 through a hinge. A sliding groove two 313 is formed in the left side of the turning rod 315. A driving rod 314 is slidably connected to the inside of the sliding groove two 313. The left side of the driving rod 314 is hinged to the fixed point block one 307 through a hinge; boundary grooves 16 are respectively formed in the left and right sides of the U-shaped frame 12.

[0038] Specifically, refer to Figure 6 , an internal groove 322 is formed in the back plate 201. A fixed cylinder 316 is fixedly connected to the top right side inside the internal groove 322. A return spring 317 is fixedly connected to the bottom side of the fixed cylinder 316. A driving block 318 is fixedly connected to the top of the return spring 317. The bottom of the driving block 318 is slidably connected to the fixed cylinder 316 through a seal; an upward moving cylinder 320 is fixedly connected to the top left side of the internal groove 322. A sealing top block 321 is slidably connected to the inside of the upward moving cylinder 320. The sealing top block 321 is located directly below the fixed point block one 307. An air pipe 319 is fixedly connected and communicated between the fixed cylinder 316 and the upward moving cylinder 320.

[0039] Preferably, the right surface of the second connecting block 312 is semi-circular, and the top of the driving block 318 is designed with an arc shape that gradually rises from front to back.

[0040] During installation, the U-shaped frame 12 is first slidably connected to the vertical block. During the sliding process, the left and right tops of the U-shaped frame 12 first contact the outer surface of the second connecting block 312. The contact force causes the second connecting block 312 to sink into the translation groove 309 and compresses the connecting spring 311. Then the U-shaped frame 12 continues to move until the boundary groove 16 corresponds to the position of the second connecting block 312. Thus, the connecting spring 311 rebounds and drives the second connecting block 312 into the boundary groove 16. Along with the movement of the U-shaped frame 12, the U-shaped frame 12 contacts the top surface of the driving block 318. The contact force causes the bottom of the driving block 318 to contact and compresses the return spring 317. During the downward movement of the driving block 318, the air inside the fixed cylinder 316 enters the upward movement cylinder 320 through the air pipe 319, causing the sealing top block 321 to move upward. The sealing top block 321 pushes the fixed point block one 307 out of the notch one 308. Thus, the first connecting block 303 loses its restriction. Thus, the two sets of labor-saving springs 302 rebound and drive the first connecting block 303 to move towards the position of the T-shaped block 202. And during the upward movement of the fixed point block one 307, it will drive the flipping rod 315 to rotate clockwise to a horizontal state through the driving rod 314, so that the right end of the flipping rod 315 abuts against the left side of the second connecting block 312, making the second connecting block 312 unable to move inward. And this state will be ensured during the movement of the first connecting block 303. And during the upward movement of the first connecting block 303, the second connecting block 312 contacts the top side of the boundary groove 16, thus providing an upward force for the U-shaped frame 12, so as to achieve the effect of labor saving during the installation process of the explosion-proof distribution box body 10.

[0041] Preferably, a pair of left and right arranged guide rails one 304 are fixedly connected to the front surface of the back plate 201. The guide rails one 304 are slidably connected to the corresponding first connecting blocks 303, so as to achieve the effect of guiding and limiting the movement of the first connecting blocks 303.

[0042] When it is necessary to maintain and disassemble the explosion-proof distribution box body 10, by reversing the positioning bolt 15, the positioning bolt 15 is removed from the T-shaped block 202, so that the first spring 208 rebounds and drives the slider 205 to move downward, and then drives the two groups of positioning inserts 209 to move inward through the connecting rod 210 to disengage from the positioning groove 14, so that the U-shaped frame 12 loses its restriction, and the U-shaped frame 12 and the explosion-proof distribution box body 10 move downward; during the downward movement, the first connecting block 303 is driven to move downward, and during the downward movement, the labor-saving spring 302 deforms to provide an upward force when the explosion-proof distribution box body 10 moves downward, which can buffer the downward movement of the explosion-proof distribution box body 10 and prevent the inertial force from being too large when the explosion-proof distribution box body 10 slides down and causing harm to the operator's body; when the U-shaped frame 12 slides down, it first loses the compression of the driving block 318, so that the return spring 317 rebounds and the driving block 318 moves upward, and then the air inside the upward moving cylinder 320 is pumped out through the air pipe 319, so that the sealing top block 321 moves downward away from the first notch 308; when the fixed point block 307 is aligned with the first notch 308 as the U-shaped frame 12 continues to move downward, the downward pressure spring 306 rebounds and drives the fixed point block 307 to insert into the first notch 308, completing the positioning of the first connecting block 303, and during the downward movement of the fixed point block 307, the driving rod 314 and the flipping rod 315 are flipped upward, so that the second connecting block 312 loses its restriction and can move left and right, and then the boundary groove 16 of the U-shaped frame 12 that continues to move downward will contact the fixed point block 307, and the fixed point block 307 moves inward and is disengaged from the U-shaped frame 12; and the auxiliary mechanism 30 returns to its original state. At the same time, the separation of the U-shaped frame 12 from the back plate 201 also completes the disassembly of the explosion-proof distribution box body 10. The above-mentioned auxiliary mechanism 30 can provide an upward pulling force to assist in the installation when the explosion-proof distribution box body 10 is installed, and can also provide a buffering force to prevent the explosion-proof distribution box body 10 from impacting the operator at high speed when the explosion-proof distribution box body 10 is disassembled; and the opening and closing of the auxiliary mechanism 30 are controlled by a mechanical trigger, which is time-saving and labor-saving without manual opening, and does not require electric power to start, so that the auxiliary mechanism 30 can adapt to more environments.

[0043] Since the explosion-proof distribution box body 10 is often installed in an environment with strong winds and sand such as a construction site or the wilderness, a layer of dust will adhere to the surface of the back plate 201. When the auxiliary mechanism 30 is opened, these dusts will affect the smooth upward movement of the first connecting block 303, and further affect the assistance provided by the labor-saving spring 302 for the upward movement of the U-shaped frame 12, thus a cleaning mechanism 40 is proposed.

[0044] Reference Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11, parallel grooves 405 are respectively formed on the left and right sides inside the cleaning box 401. A second guide rail is fixedly connected to the top of the parallel groove 405. A displacement block 407 is slidably connected to the bottom of the second guide rail. A rotating rod 402 is rotatably connected to the inner sides of the two displacement blocks 407. A roller cleaning brush 403 is fixedly connected to the outer side of the rotating rod 402. The rear surface of the roller cleaning brush 403 contacts the surface of the back plate 201. A shovel block 404 is fixedly connected to the bottom of the rear side of the cleaning box 401; the cleaning mechanism 40 further includes a pair of driving frames 420 fixedly connected to the front surface of the back plate 201. A pair of teeth are respectively fixedly connected to the upper and lower sides inside the driving frame 420. The rear teeth are engaged with a gear 421. The inner side of the gear 421 is fixedly connected to the rotating rod 402; the bottom of the cleaning box 401 is fixedly installed with a collection box 428 through a fastener.

[0045] When the first connecting block 303 moves upward, the cleaning box 401 at its top moves in the same direction. During the movement, the gear 421 rolls along the surface of the rear teeth of the driving frame 420, so that the rotating rod 402 and the roller cleaning brush 403 rotate clockwise to perform rotational cleaning on the surface in contact with the back plate 201. When the clockwise rotating roller cleaning brush 403 contacts the dust on the surface of the back plate 201, it will drive the dust downward to cooperate with the shovel block 404 below, so that the dust enters the gap between the shovel block 404 and the roller cleaning brush 403, and is collected into the collection box 428 along the inclined surface at the bottom side inside the cleaning box 401, achieving the effect of integrating the cleaning and collection of the dust on the surface of the back plate 201, cleaning the movement path of the first connecting block 303 on the back plate 201, and effectively preventing the first connecting block 303 from jamming and affecting the auxiliary mechanism 30.

[0046] Further, a scraper 426 is fixedly connected to the left and right sides inside the cleaning box 401. The scraper 426 is located directly in front of the roller cleaning brush 403 and there is a certain distance between the two; a fixed-point groove 408 is formed at the bottom of the left displacement block 407. A fixed-point spring 409 is fixedly connected to the inside of the fixed-point groove 408. A second fixed-point block 410 that is slidably connected to the fixed-point groove 408 is fixedly connected to the bottom of the fixed-point spring 409; mirror-symmetrical clamping grooves 411 are formed on the front and rear sides of the bottom of the left parallel groove 405. A sliding plate 412 is slidably connected to the inside of the clamping groove 411. A connecting frame 413 is fixedly connected to the inside of the sliding plate 412. A rolling rod 415 is rotatably connected to the inside of the connecting frame 413. A rotatable inclined rod 414 is rotatably connected to the front side of the rolling rod 415. The bottom of the inclined rod 414 is hinged to the bottom of the clamping groove 411 through a hinge.

[0047] Specifically, transverse through grooves are formed on the outer sides of the two clamping grooves 411. A third guiding groove 417 is formed at the top of the transverse through groove. A push rod 416 is slidably connected inside the transverse through groove. A third guiding block 418 is fixedly connected to the top of the push rod 416. The third guiding block 418 is slidably connected to the third guiding groove 417. A second notch 427 is formed on the outer side of the rear transverse through groove. Trigger grooves 423 are respectively formed on the left and right sides of the front surface of the back plate 201. A trigger spring 424 is fixedly connected to the inner side of the trigger groove 423. A trigger block 425 slidably connected to the trigger groove 423 is fixedly connected to the front side of the trigger spring 424. The front surface of the trigger block 425 is semicircular. The front push rod 416 extends forward and is located outside the cleaning box 401. A pressing block 419 is fixedly connected to the rear side of the left displacement block 407. The pressing block 419 extends rightward and penetrates through the surface of the connecting block cleaning box 401. A trapezoidal block 422 is arranged on the front side of the pressing block 419. The left side of the trapezoidal block 422 is fixedly connected to the driving frame 420 through a connecting member.

[0048] When the cleaning box 401 moves upward and contacts the front side of the trigger block 425, the contact force causes the trigger block 425 to sink into the interior of the trigger slot 423 and compresses the trigger spring 424. Until the notch two 427 is opposite to the position of the trigger block 425, the trigger spring 424 rebounds and drives the trigger block 425 to insert into the notch two 427. And the trigger block 425 contacts the rear push rod 416 and drives the rear push rod 416 to move forward. The push rod 416 moves and contacts the surface of the corresponding inclined rod 414, and drives the inclined rod 414 to gradually become vertical, so that the sliding plate 412 jacks up the fixed point block two 410. Thus, the displacement block 407 loses its restriction, and the return spring 406 contracts and rebounds to drive the displacement block 407 to move forward, thereby driving the rotating rod 402, the gear and the 421 roller cleaning brush 403 to move forward, so that the roller cleaning brush 403 disengages from the back plate 201 and contacts the scraper 426. At the same time, the moved gear 421 contacts the front side teeth, until the displacement block 407 is opposite to the position of the front side clamping groove 411. Thus, the fixed point spring 409 rebounds and drives the fixed point block two 410 to insert into the interior of the front side clamping groove 411, achieving the positioning after the movement of the roller cleaning brush 403; When the explosion-proof distribution box body 10 is disassembled, the cleaning box 401 will move downward with the connecting block one 303. During the downward movement, the gear 421 rolls along the surface of the front side teeth, thereby driving the gear 421 to rotate, and then driving the rotating rod 402 and the roller cleaning brush 403 to rotate. And during the rolling connection of the roller cleaning brush 403, it contacts the surface of the scraper 426, thereby scraping off the dust on the surface of the roller cleaning brush 403, thus achieving the self-cleaning effect of the roller cleaning brush 403 and ensuring the cleaning effect of the roller cleaning brush 403 during subsequent installation; And when the cleaning box 401 moves to the displacement of the trapezoidal block 422, the front push rod 416 will first contact the inclined surface at the top of the trapezoidal block 422, and drive the push rod 416 to move inward with the contact force. The push rod 416 drives the corresponding inclined rod 414 to gradually turn to the vertical state, so that the corresponding sliding plate 412 moves upward to eject the fixed point block two 410 from the interior of the clamping groove 411. Then the push rod 416 slides to the parallel surface of the trapezoidal block 422, so that the fixed point block two 410 always remains disengaged from the front side clamping groove 411. Then the pressing block 419 contacts the inclined surface of the trapezoidal block 422, and drives the pressing block 419 to move inward with the contact force, driving the displacement block 407 to move in the same direction, so that the rotating rod 402, the gear 421 and the roller cleaning brush 403 move in the same direction, until the fixed point block two 410 corresponds to the rear side clamping groove 411. Thus, the fixed point spring 409 drives the fixed point block two 410 to insert into the rear side clamping groove 411 to complete the positioning. At the same time, the roller cleaning brush 403 contacts the surface of the back plate 201 and the gear 421 meshes with the rear side teeth to return to the original state.When the above-mentioned cleaning mechanism 40 is installed on the explosion-proof distribution box body 10, it can achieve the effect of cleaning the moving path of the first connecting block 303 on the surface of the back plate 201; when the explosion-proof distribution box body 10 is disassembled, it can achieve the self-cleaning effect of the roller cleaning brush 403; and it can freely switch between the two states without a driving member, increasing the automation effect of the cleaning mechanism 40, thereby improving the utilization rate of the device.

[0049] The working principle of the present invention is as follows: Before installing the explosion-proof distribution box body 10, the back plate 201 needs to be installed on the surface of a suitable wall through fasteners such as bolts first. Then, the operator pushes the explosion-proof distribution box body 10 to insert the inner hollow part of the U-shaped frame 12 into the vertical block, and makes the protruding block 13 insert into the first guiding groove 203. Then, the explosion-proof distribution box body 10 is pushed upward until the explosion-proof distribution box body 10 moves to a suitable position. Then, the positioning bolt 15 is rotated, so that the positioning bolt 15 moves upward to contact the bottom of the slider 205 through the through groove 211 and drives the slider 205 to move upward. Thus, the positioning insert block 209 is driven by the connecting rod 210 to move outward along the through groove 211 and insert into the corresponding positioning groove 14, achieving the effect of installing the explosion-proof distribution box body 10 on the back plate 201. And during installation, through the guiding and positioning of the auxiliary installation structure, the explosion-proof distribution box body 10 can be installed quickly and conveniently.

Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
