Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a distribution box for a brewing workshop. Background Technology

[0002] Traditional Chinese Baijiu is made using solid-state fermentation, with various grains as raw materials and rice husks and other materials as auxiliary materials. Under the combined action of microorganisms in the starter culture, cellar mud, and surrounding environment, complex physicochemical changes occur, forming the unique quality and style of Chinese Baijiu.

[0003] In brewing workshops, a large amount of volatile organic compounds are used. When the vapors of these compounds mix with air in a certain proportion and reach an explosive concentration, they will burn or explode when exposed to open flames, high temperatures, electric arcs, etc. These workshops naturally become flammable and explosive hazardous areas. Explosion-proof safety must be the top priority in the electrical design of the workshops. Among them, the distribution boxes will be selected as explosion-proof to effectively prevent such dangerous situations from occurring.

[0004] However, existing explosion-proof distribution boxes typically use bolts to fix the door to the distribution box around the front side to ensure the door is stable and sealed. Using too many bolts makes it very inconvenient for staff to open the door when the distribution box needs maintenance, wasting time. Therefore, we propose a distribution box for brewing workshops to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a power distribution box for a brewing workshop, so as to solve the problem of excessive bolts fixing the door in the prior art, which makes it inconvenient to open the door when the power distribution box needs maintenance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distribution box for a brewing workshop, comprising a box body and a door, wherein the door is hinged to the front left end of the box body, and further comprising: a concave frame, wherein the concave frame is installed on the front wall of the box body and surrounds the outer wall of the door; slots, wherein three sets of slots are respectively opened on the upper, lower, and right sides of the concave frame, and each set of slots comprises three slots; a hollow column, wherein the hollow column is installed on the outer wall of the door at a position corresponding to the slot, and the hollow column is located in the inner cavity of the slot; and a connecting block, wherein the connecting block is installed on the concave frame. The outer wall corresponds to the slot; the positioning post is inserted into the top of the connecting block and extends into the inner cavity of the hollow column, and the inner cavity of the positioning post is also provided with a pressing component and a positioning component; the slots are respectively opened in the inner cavities of the connecting block and the hollow column, and each set of slots has two slots, which are located in the middle of the left and right sides of the inner cavity of the connecting block and the top of the left and right sides of the inner cavity of the hollow column; the slides are respectively opened at the front and rear ends of the left and right sides of the box; the support mechanism is set at the bottom of the box, and its top is inserted into the slide.

[0007] In a preferred embodiment, there is a gap between the outer wall and top of the hollow column and the inner wall of the slot and the bottom of the connecting block.

[0008] In a preferred embodiment, the extrusion assembly includes: a positioning post inserted into the top of the connecting block and extending into the inner cavity of the hollow post; an insert rod inserted into the top of the positioning post and extending into its inner cavity; a concave plate mounted on the bottom end of the insert rod; a first spring sleeved on the outer wall of the insert rod located in the inner cavity of the positioning post, with the upper and lower ends of the first spring respectively engaged with the top of the inner wall of the positioning post and the top of the concave plate; and two spheres respectively mounted on the left and right sides of the bottom end of the concave plate.

[0009] In a preferred embodiment, the positioning assembly includes: a support rod installed in the middle of the inner cavity of the positioning post; a spring plate, the top of which is sleeved on the outer wall of the support rod, and both ends of the spring plate extending to the lower part of the inner cavity of the positioning post; two grooves respectively formed at the bottom ends of the left and right sides of the spring plate; a positioning rod installed in the inner cavity of the groove by screws, and the outer end of the positioning rod extending through the positioning post into a slot in the inner cavity of the hollow post; and a second spring engaged with the bottom end of the inner wall of the spring plate.

[0010] In a preferred embodiment, the outer wall of the sphere is attached to the top wall surfaces of the left and right sides of the spring sheet.

[0011] In a preferred embodiment, the top cavities of the support rod and the spring plate are both arranged in matching rectangles.

[0012] In a preferred embodiment, the support mechanism includes: support rods, four of which are respectively inserted into the inner cavities of four sliding grooves, with the bottom ends of the support rods extending out of the sliding grooves; a base, which is mounted on the bottom ends of the four support rods via pins, allowing the support rods to rotate on the base under the action of the pins when they lose their limiting position; support blocks, two of which are respectively mounted on the upper and lower ends of the inner side of the support rods via pins, with the support block at the top abutting against the lower surface of the housing; and mounting holes, two of which are respectively opened on the front and rear sides of the top end of the support block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This invention allows the concave plate and sphere to move downwards by pressing down the insert rod. The sphere is compressed by a spring plate, causing it to deform and pull the positioning rod inwards. The positioning rod separates from the slot in the hollow column, allowing the positioning column to be pulled upwards and separated from the hollow column. The hollow column loses its fixation, and the stop door can be opened. The hollow column moves out of the slot together with the hollow column. Conversely, after the stop door is closed and pressed tightly against the box, pressing down the insert rod and the positioning column again can firmly fix the stop door back to the box. This allows the stop door to be easily opened when maintaining the distribution box, saving time and improving efficiency.

[0015] 2. The support mechanism of this invention can be disassembled from the box body. By moving the support rod outward, the support block can be extended outward. After the support rod is reinserted into the slide groove, the box body sits on the base. The box body and the base can be lifted together. After the support block is extended outward, it can be placed on the bracket on the wall and then fixed with bolts. Thus, the floor-standing type can be changed to the hanging type. It is flexible in use and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 This invention provides a technical solution: a power distribution box for a brewing workshop, comprising a box body 1, a door 2, a concave frame 3, slots 4, hollow columns 5, connecting blocks 6, positioning columns 7, slots 8, sliding grooves 18, and a support mechanism. The door 2 is hinged to the front left end of the box body 1. A sealing strip is affixed to the rear wall of the door 2. The concave frame 3 is installed on the front wall of the box body 1 and surrounds the outer wall of the door 2. A sealing strip is provided between the concave frame 3 and the door 2. Three sets of slots 4 are respectively located on the upper, lower, and right sides of the concave frame 3, with three slots in each set. The hollow columns 5 are installed on the outer wall of the door 2 at positions corresponding to the slots 4, and are located within the inner cavity of the slots 4. The connecting blocks 6 are installed on the outer wall of the concave frame 3 corresponding to the slots 4. Position; the positioning post 7 is inserted into the top of the connecting block 6 and extends into the inner cavity of the hollow post 5. The inner cavity of the positioning post 7 is also provided with a pressing component and a positioning component. Through the cooperation between the positioning post 7 and the pressing component and positioning component inside it, the hollow post 5 can be locked and fixed in the inner cavity of the slot 4, thereby realizing the fixation between the door 2 and the box 1; two sets of slots 8 are respectively opened in the inner cavities of the connecting block 6 and the hollow post 5, and there are two slots in each set, which are located in the middle of the left and right sides of the inner cavity of the connecting block 6 and the top of the left and right sides of the inner cavity of the hollow post 5, respectively; four sliding grooves 18 are respectively opened at the front and rear ends of the left and right sides of the box 1; the support mechanism is set at the bottom of the box 1, and its top is inserted into the sliding groove 18. The sliding groove 18 can facilitate the retraction of the support mechanism.

[0024] In practice, to ensure that the hollow column 5 can be moved out of the slot 4, there is a gap between the outer wall and top of the hollow column 5 and the inner wall of the slot 4 and the bottom of the connecting block 6.

[0025] In specific implementation, the extrusion assembly includes: a positioning post 7, an insert rod 9, a concave plate 10, a first spring 11, and two balls 12. The positioning post 7 is inserted into the top of the connecting block 6 and extends into the inner cavity of the hollow post 5; the insert rod 9 is inserted into the top of the positioning post 7 and extends into its inner cavity; the concave plate 10 is installed at the bottom end of the insert rod 9; the first spring 11 is sleeved on the outer wall of the insert rod 9 located in the inner cavity of the positioning post 7, and the upper and lower ends of the first spring 11 are respectively engaged with the top of the inner wall of the positioning post 7 and the top of the concave plate 10. The first spring 11 can easily drive the concave plate 10 and the insert rod 9 to move upward for resetting; the two balls 12 are respectively installed on the left and right sides of the bottom end of the concave plate 10. By pressing the insert rod 9 downward, the concave plate 10 and the balls 12 can be driven downward for extrusion operation.

[0026] In specific implementation, the positioning assembly includes: a support rod 13, a spring plate 14, a groove 15, a positioning rod 16, and a second spring 17. The support rod 13 is installed in the middle of the inner cavity of the positioning post 7. The top of the spring plate 14 is sleeved on the outer wall of the support rod 13, and both ends of the spring plate 14 extend to the bottom of the inner cavity of the positioning post 7. Two grooves 15 are respectively opened on the left and right bottom ends of the spring plate 14. The positioning rod 16 is installed in the inner cavity of the groove 15 by screws, and the outer end of the positioning rod 16 passes through the positioning post 7 and extends into the slot 8 in the inner cavity of the hollow post 5. Through the cooperation of the positioning rod 16 and the slot 8, the positioning post 7 can be fixed in the inner cavity of the connecting block 6 and the hollow post 5. The second spring 17 is engaged with the bottom end of the inner wall of the spring plate 14. The second spring 17 makes it easier for the deformed spring plate 14 to return to its initial state after losing external force.

[0027] In practice, in order to enable the sphere 12 to compress the spring sheet 14, the outer wall of the sphere 12 is attached to the top wall of the left and right sides of the spring sheet 14.

[0028] In practice, to ensure that the spring plate 14 is more stably fitted onto the support rod 13, the top inner cavities of both the support rod 13 and the spring plate 14 are arranged in a matching rectangular shape.

[0029] In specific implementation, the support mechanism includes: support rods 19, bases 20, support blocks 21, and mounting holes 22. Four support rods 19 are respectively inserted into the inner cavities of four sliding grooves 18, with the bottom ends of the support rods 19 extending out of the sliding grooves 18. The base 20 is mounted on the bottom ends of the four support rods 19 via pins. When the support rods 19 lose their limit position, they can rotate on the base 20 under the action of the pins. Two support blocks 21 are respectively mounted on the upper and lower ends of the inner side of the support rods 19 via pins, with the top support block 21 abutting against the lower surface of the housing 1. The top support block 21 can be bolted to the mounting hole 22. After the mounting hole 22 passes through, it is installed and fixed between the support block 21 and the housing 1. The two mounting holes 22 are respectively opened on the front and rear sides of the top of the support block 21. Since the support block 21 is installed on the support rod 19 by a pin, and the support rod 19 is connected to the base 20 by a pin, when the two are separated from the housing 1, the support rod 19 can drive the support block 21 to rotate to the outside. After the support rod 19 is fully inserted into the slide groove 18, the base 20 can retract to the lower surface of the housing 1. The housing 1 can be placed on the bracket on the wall by the support block 21 extending to the outside and fixed by bolts to realize the suspension of the housing 1.

[0030] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0031] In use, press down on the insertion rod 9. The insertion rod 9 moves the concave plate 10 and the ball 12 downwards. The ball 12 presses the spring plate 14 inwards. As the spring plate 14 deforms, it pulls the positioning rod 16 inwards. The positioning rod 16 separates from the slot 8 in the hollow column 5. At this time, the positioning post 7 moves upwards. The positioning post 7 can separate from the hollow column 5. The hollow column 5 loses its fixation, and the stop door 2 can be opened. After entering the connecting block 6 below the positioning post 7, release the insertion rod 9. Under the elastic force of the first spring 11, the concave plate 10, the ball 12, and the insertion rod 9 can move upwards and reset. The ball 12 pushes against the spring plate 14. At the same time, the spring... Plate 14 gradually returns to its initial state and moves the positioning rod 16 outward. The positioning rod 16 is inserted into the slot 8 in the inner cavity of the connecting block 6, so that the positioning post 7 can be fixed on the connecting block 6, avoiding complete disassembly and loss. When the door 2 needs to be fixed after closing, press down the insertion rod 9 again, the positioning rod 16 retracts, and the positioning post 7 is inserted into the hollow post 5. After releasing the insertion rod 9, the positioning rod 16 springs into the corresponding slot 8, fixing the hollow post 5 and the connecting block 6, so that the door 2 is fixed on the box 1 after closing, making it easier for the staff to open the door for maintenance work. The operation is simple and convenient.

[0032] In addition, when it is necessary to suspend the box 1 on the bracket on the wall, the support mechanism is removed from the box 1, the support rod 19 is rotated outward so that the support block 21 extends outward, and then the support rod 19 is reinserted into the slide groove 18. The box 1 sits on the base 20. The box 1 and the base 20 are lifted together and placed on the bracket on the wall by the outward-extending support block 21. Then it can be installed and fixed with bolts.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
