Description

Technical Field

[0001] This utility model belongs to the field of control cabinet technology, and specifically relates to an electrical control cabinet. Background Technology

[0002] Current electrical control cabinets are equipped with perfluorohexanone (PFH) fire extinguishing systems, allowing personnel to quickly extinguish open flames inside the cabinet in the event of a fire. PFH is a highly efficient fire extinguishing device and is widely used in existing technology.

[0003] However, some current perfluorohexanone fire extinguishing devices are fixed to the inner wall of the electrical control cabinet using multiple bolts, requiring the unscrewing of these bolts during installation and removal. Others are secured to the inner wall with clamps, necessitating the opening and closing of these clamps during disassembly. Neither bolted nor clamped installation allows for quick assembly and disassembly, especially crucial in the event of a fire where access to the extinguishing device is critical. The inability to quickly remove existing perfluorohexanone fire extinguishing devices from electrical control cabinets increases the risk of damage to the cabinet. Utility Model Content

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0046] Example:

[0047] like Figures 1-6 As shown, the electrical control cabinet provided in this embodiment includes a cabinet body 100, a latching assembly, and a fire extinguishing device 900. A fixing block 110 is provided on the side wall of the cabinet body 100. The fixing block 110 can be welded to the side wall of the cabinet body 100 or bolted to the side wall of the cabinet body 100. The fixing block 110 can be inside or outside the cabinet body 100. The fixing block 110 has a mounting cavity inside, and the cavity wall of the mounting cavity has an insertion hole that penetrates the fixing block 110. Preferably, the insertion hole faces the side inside the cabinet body 100. The latching assembly is installed in the mounting cavity, and the latching assembly is connected to a driving assembly for driving it to fasten or loosen. That is, the driving assembly can drive the latching assembly to fasten or loosen.

[0048] The fire extinguishing device 900 has a protrusion 910 on its outer wall. The protrusion 910 passes through an insertion hole and extends into a mounting cavity. A latching assembly placed in the mounting cavity engages with the protrusion 910, thereby securing the protrusion 910 within the mounting cavity. When the latching assembly is released, it releases the protrusion 910. In essence, when the latching assembly is engaged, it secures the protrusion 910 within the mounting cavity; when it is disengaged, it releases the protrusion 910.

[0049] With the above structure, the fire extinguishing device 900 is installed on the side wall of the cabinet 100 through the cooperation of the protrusion 910, the snap-fit ​​assembly, and the fixing block 110. Specifically, during installation, the operator holds the fire extinguishing device 900 and inserts the protrusion 910 on the fire extinguishing device 900 into the insertion hole, so that the protrusion 910 enters the installation cavity and engages with the snap-fit ​​assembly. With the help of the driving assembly, the snap-fit ​​assembly is released when the protrusion 910 is inserted. When the protrusion 910 is inserted into the designated position in the installation cavity, the driving assembly drives the snap-fit ​​assembly to lock in place. Thus, the snap-fit ​​assembly secures the protrusion 910 in the installation cavity, connecting the fire extinguishing device 900 to the side wall of the cabinet 100. When it is necessary to remove it, the operator only needs to operate the driving assembly to release the snap-fit ​​assembly, thereby releasing the protrusion 910. Then, the protrusion 910 can be easily pulled out from the installation cavity and the insertion hole, and the fire extinguishing device 900 can be quickly removed. Therefore, the fire extinguishing device 900 on the electrical control cabinet provided in this embodiment can be quickly disassembled and assembled. In the event of a fire, the time spent by the staff to obtain the fire extinguishing device 900 is less, thus enabling rapid fire extinguishing.

[0050] To ensure a more stable connection between the fire extinguishing device 900 and the side wall of the cabinet 100, in this embodiment, two protrusions 910 are provided on the side wall of the cabinet 100, one above the other. Each protrusion 910 contains the aforementioned snap-fit ​​assembly. The outer wall of the fire extinguishing device 900 also contains two protrusions 910, one above the other, and each protrusion 910 engages with the snap-fit ​​assemblies of the two fixing blocks 110. That is, during installation, the two protrusions 910 are inserted into the two fixing blocks 110 and engage with the snap-fit ​​assemblies inside the two fixing blocks 110.

[0051] An optional implementation of this embodiment is as follows: The aforementioned latching assembly includes a gripper 200 and a first rotating shaft 300 extending vertically. It should be noted that the aforementioned protrusion 910 extends horizontally into and out of the aforementioned insertion hole. The gripper 200 is rotatably mounted on the bottom wall of the mounting cavity via the first rotating shaft 300. Specifically, a circular countersunk hole is provided on the bottom wall of the mounting cavity, and the bottom of the aforementioned first rotating shaft 300 is rotatably inserted into the aforementioned circular countersunk hole. The aforementioned driving assembly is connected to the gripper 200 and is used to drive the gripper 200 to rotate around the first rotating shaft 300. A hook is provided at a position on the gripper 200 away from the first rotating shaft 300. When the gripper 200 rotates around the first rotating shaft 300, the hook rotates in the horizontal plane. A barb 911 is provided on the outer wall of the end of the aforementioned protrusion 910 away from the fire extinguishing device 900, and the barb 911 can cooperate with the aforementioned hook.

[0052] When the gripper 200 rotates in the first direction and its hook engages the barb 911, the protrusion 910 cannot be removed from the mounting cavity, and thus remains within the mounting cavity. When the gripper 200 rotates in the second direction and its hook disengages from the barb 911, the latching assembly releases the protrusion 910, allowing it to be removed from the mounting cavity. The second direction is opposite to the first direction. Thus, by driving the gripper 200 in both forward and reverse directions, the latching assembly can either engage or disengage the protrusion 910.

[0053] Of course, the above-mentioned buckle assembly can also be a locking rod that can slide vertically in the mounting cavity. The drive assembly connects to the locking rod and drives the locking rod to slide vertically. An axially vertical locking hole is provided on the protrusion 910. Before the protrusion 910 is inserted into the mounting cavity, the drive assembly drives the locking rod to move up to the highest point. After the protrusion 910 is inserted into the mounting cavity, the drive assembly drives the locking rod to move down and insert into the locking hole.

[0054] An optional implementation of this embodiment is as follows: This embodiment takes the buckle assembly including a gripper 200 and a first rotating shaft 300 as an example for description. The driving assembly in this embodiment includes a slider 400, an axially vertical second rotating shaft 600, and a first gear 610, wherein:

[0055] The aforementioned mounting cavity is a square chamber. The cavity walls are defined by a first cavity wall and a second cavity wall facing each other. The insertion hole is located in the first cavity wall. The slider 400 is slidably mounted between the first and second cavity walls via a guide member, allowing the slider 400 to move back and forth between them. A toothed portion 410 extending along the sliding direction of the slider 400 is provided on its outer side wall. This toothed portion 410 can be understood as a rack, with its length direction aligned with the sliding direction of the slider 400. Specifically, the sliding direction of the slider 400 is in a horizontal plane, and the length direction of the rack is also in a horizontal plane. The slider 400 is also connected to a translation drive unit, which drives the slider 400 to move back and forth between the first and second cavity walls.

[0056] The axial direction of the second rotating shaft 600 is parallel to that of the first rotating shaft 300. The top end of the second rotating shaft 600 is rotatably connected to the top wall of the mounting cavity. Specifically, a circular recess is provided on the top wall of the mounting cavity, and the top end of the second rotating shaft 600 is rotatably placed in the circular recess. The bottom end of the second rotating shaft 600 is connected to the gripper 200. Thus, when the second rotating shaft 600 rotates, it can drive the gripper 200 to rotate. The first gear 610 is sleeved or welded to the outside of the second rotating shaft 600, so that the first gear 610 is coaxial with the second rotating shaft 600, and the first gear 610 meshes with the toothed portion 410. Thus, when the slider 400 moves back and forth between the first cavity wall and the second cavity wall, it can drive the first gear 610 to drive the second rotating shaft 600 to rotate in both directions, thereby driving the gripper 200 to rotate in both directions.

[0057] Specifically, when the slider 400 slides toward the first cavity wall, the tooth 410 drives the first gear 610, the second rotating shaft 600, and the gripper 200 to rotate in the second direction, thereby causing the hook on the gripper 200 to disengage from the barb 911 on the protrusion 910, so that the gripper 200 releases the protrusion 910; when the slider 400 slides toward the second cavity wall, the tooth 410 drives the first gear 610, the second rotating shaft 600, and the gripper 200 to rotate in the first direction, thereby causing the hook on the gripper 200 to engage with the barb 911 on the protrusion 910, so that the gripper 200 grips the protrusion 910.

[0058] With the above structure, the operator only needs to operate the above translation drive unit to make the slider 400 move back and forth between the first cavity wall and the second cavity wall, thereby realizing the latching assembly to fasten or release the protrusion 910, which is simple and convenient to operate.

[0059] Of course, the aforementioned drive assembly can also be screwed onto the side wall of the fixing block 110 with a screw rod. The front end of the screw rod is hinged to the outer side wall of the aforementioned gripper 200. In this way, when the operator rotates the screw rod, the screw rod can enter and exit the aforementioned mounting cavity from the side. When the screw rod moves into the mounting cavity, the screw rod pushes the aforementioned gripper 200 inward, thereby causing the gripper 200 to rotate in the first direction. When the screw rod moves out of the mounting cavity, the screw rod pulls the gripper 200 outward, thereby causing the gripper 200 to rotate in the second direction.

[0060] To ensure that the protrusion 910 is more stably locked in the mounting cavity, in this embodiment, two barbs 911 are provided on the protrusion 910, and the two barbs 911 are respectively provided on both sides of the protrusion 910. There are two sets of snap-fit ​​components in the mounting cavity, and the two sets of snap-fit ​​components correspond one-to-one with the two barbs 911. There are two second rotating shafts 600 and two first gears 610. The two opposite outer walls of the slider 400 are provided with the teeth 410. The two first gears 610 respectively mesh with the teeth 410 on the two opposite outer walls of the slider 400. The two second rotating shafts 600 are respectively connected to the two grippers 200. In this way, the protrusion 910 can be fastened from both sides by using two sets of snap-fit ​​components.

[0061] Optionally, the guide member includes two slide rods 500, with both ends of the slide rods 500 connected to the first cavity wall and the second cavity wall, respectively. Optionally, the slide rods 500 can be welded or heat-fused to the first and second cavity walls, or they can be connected by insertion. The axial direction of the slide rods 500 is parallel to the central axis of the insertion hole, and the two slide rods 500 are arranged in parallel. The slider 400 has two sliding holes that penetrate the slider 400, and the two slide rods 500 are slidably inserted into the sliding holes. The two slide rods 500 can prevent the slider 400 from rotating and can effectively guide the slider 400.

[0062] Of course, the aforementioned guide can also be a guide rail installed on the top wall of the mounting cavity, with the aforementioned slider 400 slidingly engaging with the guide rail. One end of the guide rail is in contact with the aforementioned first cavity wall, and the other end of the guide rail is in contact with the aforementioned second cavity wall.

[0063] Optionally, in this embodiment, the bottom end of the second rotating shaft 600 can be connected to the aforementioned gripper 200 via a spline, thereby enabling the second rotating shaft 600 to drive the gripper 200 to rotate. Another embodiment of this work is as follows:

[0064] A horizontally extending connecting rod 620 is connected to the bottom end of the second rotating shaft 600. A vertically extending lever 630 is fixed to the end of the connecting rod 620 opposite to the second rotating shaft 600, and the lever 630 is located below the connecting rod 620. A travel groove 210 is formed on the top surface of the gripper 200. The width of the travel groove 210 is adapted to the outer diameter of the lever 630. The lever 630 is inserted into the travel groove 210, and its outer wall is in contact with the side wall of the travel groove 210. In this configuration, the lever 630 is not coaxial with either the first rotating shaft 300 or the second rotating shaft 600. When the second rotating shaft 600 drives the lever 630 to rotate via the connecting rod 620, the lever 630 inserted into the travel groove 210 will drive the gripper 200 to rotate. Optionally, the lever 630 overlaps the bottom of the travel groove 210.

[0065] An optional implementation of this embodiment is as follows: The translation drive unit includes a vertically axial third rotating shaft 700 and a second gear 720. A through circular hole is provided on the top wall of the mounting cavity, which penetrates the top wall of the fixing block 110. The third rotating shaft 700 is rotatably inserted into the through circular hole. A handle 710 is installed at the top of the third rotating shaft 700, located above the fixing block 110. The handle 710 rests on the top wall of the fixing block 110. The second gear 720 is sleeved or welded to the outside of the third rotating shaft 700 and is coaxial with the third rotating shaft 700. The second gear 720 meshes with the toothed portion 410. It should be noted that there is only one third rotating shaft 700 and one second gear 720, and the second gear 720 meshes with one toothed portion 410. Thus, turning the handle 710 will drive the third shaft 700 and the second gear 720 to rotate. Since the second gear 720 meshes with the teeth 410, the rotating second gear 720 can drive the slider 400 to translate between the first cavity wall and the second cavity wall.

[0066] Of course, the translation drive unit can also be a lever block, which is fixed to the top wall of the slider 400. A slide rail communicating with the mounting cavity is provided on the top wall of the fixed block 110. The slide rail extends from the first cavity wall to the second cavity wall. The lever block is slidably placed in the slide rail. When the operator applies a force to the lever block, the lever block is driven to translate in the slide rail, thereby driving the slider 400 to translate between the first cavity wall and the second cavity wall.

[0067] More preferably, the translation drive unit in this embodiment further includes an elastic element disposed between the slider 400 and the first cavity wall, so that the slider 400 is elastically connected to the first cavity wall. Specifically, the elastic element is a spring, with its two ends respectively abutting against the slider 400 and the first cavity wall, and the spring sleeved on the slide rod 500. Thus, when the slider 400 moves toward the first cavity wall, causing the gripper 200 to rotate in the second direction, the gripper 200 releases the protrusion 910, at which point the slider 400 compresses the spring; conversely, the spring rebounds and returns to its original position. With the help of the spring, the two grippers 200 are in a clamped state in their natural state. When the barb 911 on the protrusion 910 enters between the two grippers 200, the two grippers 200 separate, causing the slider 400 to compress the spring. After the barb 911 on the protrusion 910 enters between the two grippers 200, the spring rebounds, causing the slider 400 to move automatically toward the second cavity wall, thereby causing the two grippers 200 to automatically come together and hook the barb 911 on the protrusion 910. Based on this, in this embodiment, the end wall of the hook body of the gripper 200 is set as a first guide slope, and the end walls of the barbs 911 on the protrusion 910 are all set as second guide slopes. When the barbs 911 of the protrusion 910 enter the insertion hole, the second guide slope cooperates with the first guide slope. During the further insertion of the protrusion 910, the two grippers 200 are opened. At this time, the buckle assembly can be opened without the help of the handle 710, the third rotating shaft 700 and the second gear 720. When the barbs 911 of the protrusion 910 enter between the two grippers 200, the spring rebounds and the two grippers 200 hook the two barbs 911 on the protrusion 910.

[0068] An optional implementation of this embodiment is as follows: In order to facilitate the disassembly and assembly of the components in the mounting cavity, the fixing block 110 in this embodiment actually includes a block body and a cover plate. The mounting cavity is opened on the front end face of the block body, and the cover plate is fixed to the front end face of the block body by bolts. When it is necessary to disassemble and assemble the components in the mounting cavity, the cover plate is removed.

[0069] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
