Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to a fire extinguisher box assembly that can be opened and closed quickly. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are the most common fire-fighting tool, and care must be taken when using them to avoid accidents. When fire extinguishers are in public places, they should be stored in fire extinguisher boxes to prevent damage from external objects and ensure their continued use. Currently, the most common type of fire extinguisher box is the floor-standing box. To facilitate retrieval, these boxes typically have two doors: a front door and an upper door. The upper door latches the front door, and opening the upper door automatically opens the front door. However, current fire extinguisher boxes have the following technical problems in practical use: For fire extinguishing, two fire extinguishers are usually placed inside the box, and floor-standing boxes are generally placed against a wall. The upper lid lacks a corresponding limiting device after opening, causing it to easily rotate back and close again after the user stops pushing, making it difficult to quickly retrieve all the fire extinguishers and resulting in poor usability. Utility Model Content

[0003] The present invention aims to provide a fire extinguisher box assembly that can be quickly opened and closed, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick-opening and closing fire extinguisher box assembly includes a placement box, a front door rotatably connected to the placement box, a rotating rod rotatably connected to the placement box, an upper door connected to the rotating rod, a latch plate connected to the upper door, the latch plate cooperating with the front door, a mounting groove provided on the side wall of the placement box, a ratchet connected to the rotating rod, the ratchet located inside the mounting groove, an adjusting rod rotatably connected to the inner side of the mounting groove, a mounting block connected to the adjusting rod, a pawl rotatably connected to the mounting block, the pawl cooperating with the ratchet, a spring connected to the mounting block, the free end of the spring connected to the pawl, a turning block connected to the adjusting rod, a positioning rod slidably connected to the turning block, and a positioning hole provided in the placement box, the positioning rod cooperating with the positioning hole, and several sets of positioning holes provided.

[0006] Preferably, the screwing block is provided with a storage groove, the positioning rod is connected to a limiting block, the limiting block is slidably connected to the storage groove, and the limiting block cooperates with the positioning hole.

[0007] Preferably, the twisting block is made of ferrous material, and the positioning rod is connected to an adsorption magnet.

[0008] Preferably, a placement cylinder is connected to the inside of the placement box.

[0009] Preferably, the front door is connected to an observation window.

[0010] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0011] (1) This technical solution achieves one-way limiting of the upper box door through the cooperation of ratchet and pawl. When the upper box door is to be turned open, there is no limiting effect. Users can easily and quickly turn the upper box door upward to open the fire extinguisher box. After the upper box door is turned, the upper box door will not turn back due to the limiting of the ratchet and pawl, which prevents the upper box door from covering the fire extinguisher box again. This allows users to quickly take out all the fire extinguishers, greatly improving the practicality of the fire extinguisher box. The angle of the pawl can be adjusted by turning the positioning rod, which can then adjust the upper box door to reset. The structure is simple, easy to use, and the practicality is greatly improved.

[0012] (2) This technical solution uses an adsorption magnet to make the positioning rod and the limiting block stably inserted into the positioning hole, which improves the stability of the pawl operation. The setting of the storage groove and the limiting block prevents the positioning rod from slipping out of the twisting block, further improving the stability of the device.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] like Figures 1 to 7 The fire extinguisher box assembly shown includes a storage box 1, a front door 2 rotatably connected to the storage box 1, a rotating rod 7 rotatably connected to the top rear side of the storage box 1, an upper door 17 connected to the rotating rod 7, and a latch 3 connected to the upper door 17. The latch 3 cooperates with the front door 2. When the upper door 17 is latched, the latch 3 can restrict the forward rotation of the front door 2. Figure 4 As shown, the side wall of the placement box 1 has a mounting groove 5. A rotating rod 7 is connected to a ratchet 8, which is located inside the mounting groove 5. An adjusting rod 9 is rotatably connected to the inside of the mounting groove 5. The adjusting rod 9 is connected to a mounting block 10, which is rotatably connected to a pawl 11. The pawl 11 cooperates with the ratchet 8 and can engage with the ratchet 8. A spring 16 is connected to the mounting block 10, and the free end of the spring 16 is connected to the pawl 11. The adjusting rod 9 is connected to a turning block 4, which is located outside the mounting groove 5. A positioning rod 14 is slidably connected to the turning block 4. The placement box 1 has a positioning hole 15, which cooperates with the positioning hole 15. The positioning rod 14 can be inserted into the positioning hole 15. Inside the 5, there are two sets of positioning holes 15, which are arranged sequentially from top to bottom along the placement box 1. The rotating block 4 is provided with a storage groove 19. The positioning rod 14 is connected to a limit block 13. The limit block 13 is slidably connected to the storage groove 19. The limit block 13 and the positioning hole 15 cooperate with each other. The limit block 13 can be inserted into the positioning hole 15. The diameter of the limit block 13 is larger than the diameter of the positioning rod 14. The diameters of the storage groove 19 and the positioning hole 15 are the same as the diameter of the limit block 13. The rotating block 4 is made of iron material. The positioning rod 14 is connected to an adsorption magnet 12, so that the adsorption magnet can be tightly adsorbed on the rotating block 4, preventing the positioning rod 14 and the limit block 13 from sliding outward.

[0023] The inside of the storage box 1 is connected to a storage cylinder 6, and fire extinguishers can be placed inside the storage cylinder 6. Several sets of storage cylinders 6 can be set according to the actual needs of placing fire extinguishers. The front door 2 is connected to an observation window 18, which is made of transparent material. The storage status of fire extinguishers in the fire extinguisher box can be observed through the transparent window, which is convenient for timely replacement of fire extinguishers.

[0024] The following is Figure 2 and 6 Taking the opening of the upper box door 17 as an example, we will further describe it. Figure 2 and Figure 5As shown, the limit block is inserted into the positioning hole 15, preventing the turning block 4 and adjusting rod 9 from rotating. Under the force of the spring 16, the pawl 11 inserts between two adjacent sets of ratchet teeth on the ratchet 8, allowing the ratchet 8 to rotate counterclockwise. To open the upper compartment door 17, simply rotate the upper compartment door 17 counterclockwise. The rotating rod 7 rotates counterclockwise with the upper compartment door 17. Since the pawl 11 does not restrict the counterclockwise rotation of the ratchet 8, the upper compartment door 17 can be opened quickly (the upper compartment door 17 rotates counterclockwise). (i.e., open), after the upper box door 17 is opened, the latch 3 no longer presses against the front box door 2, and the front box door 2 also rotates clockwise and opens forward. When the upper box door 17 is open, due to the elastic force of the spring 16, the pawl 11 is still locked between the two adjacent sets of ratchet teeth of the ratchet 8. At this time, the pawl 11 will restrict the clockwise rotation of the ratchet 8, thus preventing the upper box door 17 from rotating clockwise, and thus keeping the upper box door 17 in the open state; thus, it is possible to take out all fire extinguishers; when it is necessary to close the upper box door 17, Figure 5 For example, pull the magnetic magnet 12 to the left. The magnetic magnet 12 drives the positioning rod 14 and the limiting block 13 to move to the left, so that the limiting block 13 slides out of the positioning hole 15 and into the storage slot 19. At this time, the twisting block 4 can rotate relative to the placement box 1, which can drive the adjusting rod 9 to rotate. Rotate the twisting block 4 and the adjusting rod 9 clockwise, so that the mounting block 10 rotates with the adjusting rod 9, so that the pawl 11 rotates away from the two adjacent sets of ratchet teeth of the ratchet 8. After the twisting block 4 rotates 180 degrees, the limiting block 13 can be inserted into the positioning hole 15 on the lower side of the placement box 1. At this time, the pawl 11 no longer has a limiting effect on the ratchet 8, so the front box door 2 and the upper box door 17 can be reset. After the upper box door 17 is reset, rotate the mounting block 10 so that the pawl 11 can be locked into the two adjacent sets of ratchet teeth of the ratchet 8 again.

[0025] The specific implementation process is as follows:

[0026] When using the fire extinguisher, place it in the storage container 6. When needed, open the upper door 17 and the front door 2 to take out the fire extinguisher. After use, return the front door 2 and the upper door 17 to their original positions.
