DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0021] like Figures 1 to 4 A safe and environmentally friendly gas fire extinguishing device is shown, comprising a protective box 1 and a fire extinguisher 2, wherein the fire extinguisher 2 is connected to the protective box 1 and can be directly placed in the protective box 1, wherein a first box door 14 is connected to the front side of the protective box 1, wherein the protective box 1 is connected to a closed frame 4, wherein the closed frame 4 is rotatably connected to a bidirectional threaded rod 7, wherein the right end of the bidirectional threaded rod 7 is rotatably connected to the protective box 1, wherein both ends of the bidirectional threaded rod 7 are respectively threadedly connected to clamping plates 3, wherein the bidirectional threaded rod 7 comprises a forward threaded section and a reverse threaded section, namely, two clamping plates 3 are respectively threadedly connected to the forward threaded section and the reverse threaded section, The clamping plate 3 is in contact with the inner wall of the top of the protection box 1, and the side wall of the protection box 1 plays a role in limiting the rotation of the clamping plate 3. The bidirectional threaded rod 7 is connected to the driven bevel gear 8. The protection box 1 is rotatably connected to the rotating rod 5, and the rotating rod 5 is located on the inner side of the closed frame 4. The rotating rod 5 is connected to the active bevel gear 11 and the twisting block 10. The twisting block 10 is located on the outer side of the protection box 1. The active bevel gear 11 is meshed with the driven bevel gear 8. The rotating rod 5 is connected to the carrying belt 13. The closed frame 4 is provided with a through hole 16. The free end of the carrying belt 13 passes through the through hole 16 and is connected to the first box door 14.

[0022] A positioning rod 19 is slidably connected to the side wall of the through hole 16, and the positioning rod 19 is connected to the mounting frame 18. The positioning rod 19 is sleeved with a spring 20, and the two ends of the spring 20 are respectively connected to the side wall of the through hole 16 and the mounting frame 18. The mounting frame 18 is rotatably connected to a rotating roller 17. There are two groups of rotating rollers 17, and the two groups of rotating rollers 17 are respectively located on the left and right side walls of the through hole 16. The rotating rollers 17 are in conflict with the carrying belt 13, that is, the carrying belt 13 is located between the two groups of rotating rollers 17.

[0023] The rotating rod 5 is connected to a positioning ring 12, and two groups of positioning rings 12 are provided. The side wall of the protective box 1 is connected to a second box door 6. The protective box 1 is connected to a friction tube 9. The twisting block 10 is rotatably connected to the friction tube 9. The friction tube 9 can increase the resistance of the twisting block 10 during rotation. The protective box 1 and the first box door 14 are respectively connected to magnets 15, and the two groups of magnets 15 attract each other.

[0024] The specific implementation process is as follows:

[0025] like Figure 1 and Figure 3 As shown, when the first box door 14 is closed, the carrying belt 13 is rolled up on the rotating rod 5, and the carrying belt 13 is located between the two sets of positioning rings 12. At this time, the two clamping plates 3 clamp the fire extinguisher 2 and fix it in the protective box 1. When the first box door 14 is opened, as the first box door 14 rotates, the first box door 14 pulls the carrying belt 13 to move, thereby causing the rotating rod 5 to rotate, and the active bevel gear 11 rotates with the rotating rod 5, thereby driving the driven bevel gear 8 and the two-way threaded rod 7 to rotate. Since the side wall of the protective box 1 acts as a rotation limit for the clamping plate 3, as the two-way threaded rod 7 rotates, the two sets of clamping plates 3 move outwards along the two-way threaded rod 7 at the same time, thereby releasing the clamping of the fire extinguisher 2. When the first box door 14 is fully opened, the clamping plate 3 moves completely to both sides, so that the fire extinguisher 2 can be quickly taken out, and the two sets of rotating rollers are made to rotate by the spring 20. 17 clamps the carrying rope to prevent the carrying rope from folding during movement, and the positioning rod 19 allows the installation frame 18 to move stably and smoothly; when placing a new fire extinguisher 2, place the fire extinguisher 2 between the two clamping plates 3, and directly close the first box door 14. After the first box door 14 is closed, due to the action of the spring 20 and the rotating roller 17, the excessively long carrying belt 13 will not enter the closed frame 4, thereby preventing the carrying belt 13 on the winding and rotating rod 5 from loosening. After the first box door 14 is closed, the twisting block 10 can be rotated, and the rotating rod 5 can be rotated by rotating the twisting block 10. The rotating rod 5 rotates the winding and carrying belt 13 while rotating the bidirectional threaded rod 7, thereby causing the two clamping plates 3 to move inward along the bidirectional threaded rod 7 to complete the clamping of the fire extinguisher 2. The second box door 6 can be opened later to inspect the active bevel gear 11, etc.

[0026] The present technical solution can drive the two-way threaded rod 7 to rotate while opening the first box door 14, thereby releasing the clamping of the clamping plate 3 on the fire extinguisher 2, and there is no need to spend time and effort to open the clamping hoop after opening the door, so that the fire extinguisher 2 can be quickly taken out when the door is opened, saving time and the whole taking-out process is simple. The clamping is completed by driving the clamping plate 3 to move by the two-way threaded rod 7 to improve the clamping stability. After closing the door, the load-bearing rope is located in the protection box 1 to prevent the protection rope from leaking out and being damaged by external hooks or being pulled by mistake, thereby improving the stability of the device. The active bevel gear 11 is protected by the closed frame 4 to prevent the active bevel gear 11 from being damaged when taking and placing the fire extinguisher 2, thereby improving the stability of the device. The positioning ring 12 allows the load-bearing rope to be smoothly retracted on the rotating rod 5. It is convenient to inspect and repair the active bevel gear 11, etc. through the second box door 6; the twisting block 10 will not rotate easily through the friction cylinder 9, thereby improving the stability of the device; the protective box 1 and the first box door 14 are respectively connected with magnets 15, and the two groups of magnets 15 attract each other, so that the first box door 14 can be stably closed and quickly opened at the same time, which is convenient for quickly opening the protective box 1 to take out the fire extinguisher 2 for easy use; the carrying belt 13 is clamped by the cooperation of two groups of rotating rollers 17 and the spring 20, so that the carrying belt 13 will not be scattered randomly in the closed frame 4, and it is convenient to stably reel the carrying belt 13 on the rotating rod 5 later, so as to avoid the carrying belt 13 being scattered randomly in the closed frame 4 after closing the door, and at the same time avoid the carrying belt 13 reeled on the rotating rod 5 from loosening.

[0027] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
