Description

Technical Field

[0001] This invention relates to the technical field of portable fire extinguishers, specifically a fixed structure for a portable fire extinguisher based on a mini fire truck. Background Technology

[0002] Mini fire trucks are usually modified from electric vehicles and are mostly used for rapid control of small fires in communities, factories, and other areas. They can quickly transport fire-fighting equipment to the fire site.

[0003] Transporting fire extinguishers is one of the important functions of mini fire trucks. However, due to the generally poor suspension of electric vehicles and the large margin of traditional fire extinguisher racks, frequent collisions between fire extinguishers and the racks or between the fire extinguishers and each other during transportation can easily lead to malfunctions. Therefore, we propose a portable fire extinguisher fixing structure based on mini fire trucks. Summary of the Invention

[0022] Please see Figure 1-6 This invention provides a technical solution: a portable fire extinguisher fixing structure based on a mini fire truck, including a cabinet 1. The opening of the cabinet 1 is located on its side. The opening of the cabinet 1 should also be provided with a cabinet door. When the cabinet door is opened, it is parallel to the ground and can provide a load-bearing function. This is a known technology and will not be described in detail. On the two corresponding side walls inside the cabinet 1, there are movable plates 3 connected to each other by slide rails 2. The movable plates 3 can slide to the outside of the cabinet 1 by slide rails 2. A rotating disk 4 is movably connected to the inner side wall of one movable plate 3. One end of a rotating rod 5 is fixedly connected to one side of the rotating disk 4. The other end of the rotating rod 5 is movably connected to another movable plate 3 by a bearing. A clamping mechanism 6 is provided on the rotating rod 5 for fixing the fire extinguisher. A movable mechanism 7 is provided on the rotating rod 5 for fixing the side and head of the fire extinguisher. A positioning tube 8 is also fixedly connected to one side of the rotating disk 4 for inserting into the bottom of the fire extinguisher, and the positioning tube 8 is opposite to the clamping mechanism 6.

[0023] The number of clamping mechanisms 6 is not less than three. The clamping mechanism 6 includes a fixed plate 61, a fixed arc plate 62, a movable arc plate 63, and a magnetic block 64. One side of the fixed plate 61 is fixedly connected to the rotating rod 5. The outer side of the fixed arc plate 62 is fixedly connected to the other side of the fixed plate 61. One end of the fixed arc plate 62 is movably connected to one end of the movable arc plate 63. The other end of the movable arc plate 63 and the other end of the fixed arc plate 62 are both equipped with magnetic blocks 64, and the two attract each other, so that the movable arc plate 63 and the fixed arc plate 62 are spliced ​​together to form a complete ring to fix the fire extinguisher. The fixed arc plates 62 on adjacent clamping mechanisms 6 are staggered to avoid restricting the movement of the movable arc plate 63.

[0024] The movable mechanism 7 includes a movable plate 71, a pressure pad 72, an annular groove 73, an annular guide groove 74, a guide block 75, an elastic plate 76, an arc-shaped pressure plate 77, and a protective pad 78. The movable plate 71 is sleeved on the rotating rod 5 through its central through hole. To ensure that the movable plate 71 rotates with the rotating rod 5, the rotating rod 5 adopts a prism structure. A U-shaped block 9 is fixedly connected to the inner side wall of the cabinet 1. The gap between the movable plate 71 and the movable plate 3 is opposite to the U-shaped block 9. To ensure that the U-shaped block 9 can be smoothly inserted into the gap, the two ends of the U-shaped block 9 are chamfered. On the other side of the movable plate 71, a pressure pad 72 is set at the position corresponding to the positioning tube 8 for fixing the fire extinguisher head. A hook 14 is also set on the other side of the movable plate 71 for fixing the fire extinguisher pin. The fire extinguisher pin can be hung on the hook 14. When the fire extinguisher is removed from the clamping mechanism 6, the pin can be pulled out smoothly, which is convenient for the fire extinguisher to be put into use quickly. At the same time, since the installation pin is perpendicular to the axis of the fire extinguisher, the movable plate 71... 1. The connection between the hook 14 and the mounting pin can drive the fire extinguisher to move along its axis, so that the bottom of the fire extinguisher can be inserted into or disengaged from the positioning tube 8. Annular grooves 73 are provided on the other side of the movable disc 71 and at corresponding positions on the rotating disc 4. Annular guide grooves 74 are provided on the side walls of the annular grooves 73. The two ends of several elastic plates 76 are respectively inserted into two annular grooves 73, and guide blocks 75 are fixedly connected to the elastic plates 76 at positions corresponding to the annular guide grooves 74. The guide blocks 75 are slidably connected within the annular guide grooves 74. Several magnetic blocks 10 are embedded in the bottom wall of the annular grooves 73. Magnetic blocks 11 are embedded in both ends of the elastic plates 76. When magnetic blocks 10 and 11 are attracted, the elastic plates 76 are opposite to the clamping mechanism 6. The cross-section of the annular guide groove 74 is fan-shaped, which can accommodate the movement of the guide blocks 75 when the elastic plates 76 deform. An arc-shaped pressure plate 77 is fixedly connected to the inner side of the elastic plates 76. A protective pad 78 is provided on the side of the arc-shaped pressure plate 77 away from the elastic plates 76.

[0025] The elastic plate 76 is an elastic steel sheet. The movement of the movable disc 71 in the direction of the rotating disc 4 causes the elastic plate 76 to deform inward, which can press against the side of the fire extinguisher.

[0026] A crossbar 12 is fixedly connected between the two movable plates 3 and on the upper part outside the rotating disk 4. A lever 13 is fixedly connected to the lower side of the crossbar 12. The lever 13 is on the movement trajectory of the elastic plate 76 following the movement of the rotating disk 4.

[0027] When using this equipment, to store the fire extinguisher, open the movable arc plate 63, place the fire extinguisher into the fixed arc plate 62, close the movable arc plate 63 so that it is fixed to the fixed arc plate 62 by magnetic block 64, hang the safety pin of the fire extinguisher on the hook 14, move the elastic plate 76 so that each elastic plate 76 is opposite to each fire extinguisher, the protective pad 78 is in contact with the side of the fire extinguisher, and the magnetic blocks 10 and 11 are attracted. Then push the two movable plates 3 into the cabinet 1 so that the U-shaped block 9 is inserted into the gap between the movable plate 71 and the movable plate 3. The movable plate 71 moves towards the rotating plate 4, the pressure pad 72 pushes the head of the fire extinguisher so that its bottom is inserted into the positioning tube 8, and at the same time the elastic plate 76 deforms towards the fire extinguisher. The arc-shaped pressure plate 77 presses the protective pad 78 tightly against the side of the fire extinguisher to fix its position, and close the cabinet door.

[0028] When retrieving a fire extinguisher, open the cabinet door, pull out the movable plate 3, the U-shaped block 9 disengages from the gap between the movable plate 71 and the movable plate 3, the elastic plate 76 rebounds, the movable plate 71 moves away from the rotating plate 4, the hook 14 pulls the safety pin, causing the bottom of the fire extinguisher to disengage from the positioning tube 8, push the rotating plate 4 downwards, the lever 13 blocks the elastic plate 76 to expose the fire extinguisher, open the movable arc plate 63, and retrieve the fire extinguisher. During the retrieval process, the safety pin of the fire extinguisher is pulled out by the hook 14, and the fire extinguisher can be used directly. Continue to push the rotating plate 4 downwards to retrieve other fire extinguishers.
