Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, in particular to a gas fire extinguisher. Background Art

[0002] Gas fire extinguishing is a fire extinguishing system that uses a fire extinguishing agent that is usually in gaseous form at room temperature and atmospheric pressure to extinguish fires. It is generally composed of a fire extinguishing agent storage bottle, a control start valve group, a delivery pipeline, a nozzle, etc. Some also have an inert gas storage bottle for pressurized drive. When in use, the inert gas bottle is opened to allow the inert gas to spray out, thereby blocking oxygen and extinguishing the combustion. It usually does not produce any residual objects after extinguishing the fire, and is a better form of fire extinguishing.

[0003] However, in actual use, gas fire extinguishing devices are usually set up in fixed positions. This is because the inert gas storage cylinders are too large and inconvenient to transport. At the same time, the gas that can be stored in smaller gas cylinders is also relatively limited, resulting in unsatisfactory actual fire extinguishing effects. Therefore, a gas fire extinguishing device that can be easily transported is needed. At the same time, when in use, the gas cylinder needs to be replaced in time after it is used up. The traditional structure is not convenient to operate when it is fixed, and a device is also needed to facilitate the installation and placement of gas cylinders. Utility Model Content

An extrusion bolt is rotatably connected to the position corresponding to the center of the clamping piece inside the side wall of the clamping plate, and one end of the extrusion bolt rotates with the clamping piece through a bearing.

[0012] Preferably, a torsion spring is provided on one side of the gear rod, the gear rod is rotatably connected to the inside of the mounting frame via a rotating shaft, and the racks at the top and bottom of the gear rod are fixedly connected to different sliding blocks at both ends of the mounting frame respectively.

[0013] Preferably, the bottom of the gas cylinder is in contact with the placement plate, and a connecting valve is installed on the top of the gas cylinder, a conduit is provided on one side of the connecting valve, and a control switch is provided on the top of the connecting valve.

[0014] Preferably, the side wall of the baffle away from the gas cylinder is rotatably connected to a winding wheel, the outer wall of the winding wheel is circumferentially connected to a delivery pipe, and one end of the delivery pipe passes through the center of the winding wheel and is rotatably connected to the catheter.

[0015] Preferably, a slot corresponding to the gas cylinder is provided on the top of the placement plate, and a fixing plate is provided on the side of the bottom of the placement plate away from the rotating wheel, and the height of the fixing plate corresponds to the bottom position of the rotating wheel.

[0030] like Figure 1 , Figure 3 As shown, the clamping plate 4 is arc-shaped, and a clamping piece 6 is provided on one side of the clamping plate 4 away from the mounting frame 3 and close to the gas cylinder 2. An extrusion bolt 601 is rotatably connected to the inner side wall of the clamping plate 4 and the position corresponding to the center of the clamping piece 6. One end of the extrusion bolt 601 rotates with the clamping piece 6 through a bearing, and the clamping piece 6 can be further driven by rotating the extrusion bolt 601, thereby further squeezing the gas cylinder 2 to keep it fixed.

[0031] like Figure 4 , Figure 5 As shown, a torsion spring 502 is provided on one side of the gear rod 501, and the gear rod 501 is rotatably connected to the inside of the mounting frame 3 through a rotating shaft. The racks 302 at the top and bottom of the gear rod 501 are respectively fixedly connected to different sliding blocks 301 at both ends of the mounting frame 3, and the toothed belt 5 is pulled, so that the toothed belt 5 rotates and drives the two gear rods 501 to rotate accordingly, thereby causing the racks 302 at the top and bottom of the gear rod 501 to move, thereby driving the sliding block 301 to move to the inside of the mounting frame 3.

[0032] like Figure 1 , Figure 2As shown, the bottom of the gas cylinder 2 is fitted with the placement plate 1, and a connecting valve 201 is installed on the top of the gas cylinder 2, a conduit 202 is provided on one side of the connecting valve 201, and a control switch is provided on the top of the connecting valve 201, and a card slot corresponding to the gas cylinder 2 is provided on the top of the placement plate 1, and a fixing plate 102 is provided on the side of the bottom of the placement plate 1 away from the rotating wheel 101, and the height of the fixing plate 102 corresponds to the bottom position of the rotating wheel 101, and the baffle 7 can be easily pulled by pulling the handle 701 to drive the placement plate 1 to tilt, thereby releasing the fixing plate 102 from the ground, and then the device can be pulled to move through the rotating wheel 101, so as to conveniently drive the device to be transported to different locations.

[0033] like Figure 1 , Figure 2 As shown, the side wall of the baffle 7 is rotatably connected to the side away from the gas cylinder 2 with a winding wheel 702, and the outer wall of the winding wheel 702 is circumferentially connected to the delivery pipe 703, and one end of the delivery pipe 703 passes through the center of the winding wheel 702 and is rotatably connected to the conduit 202.

Since the delivery pipe 703 passes through the center of the winding wheel 702 and is rotatably connected to the conduit 202, there is no need to pull the delivery pipe 703 before connecting it to the conduit 202 when in use.

[0034] Working principle: When in use, the baffle plate 7 can be conveniently pulled by the handle 701 to make the placement plate 1 tilt, so that the fixing plate 102 is released from the ground, and the device can be pulled to move through the rotating wheel 101, so that the device can be conveniently driven and transported to different positions. At the same time, when in use, it can also be conveniently connected with the delivery pipe 703 through the conduit 202, and when extinguishing a fire, the delivery pipe 703 can be conveniently pulled directly, so as to be conveniently moved to different positions. By opening the connecting valve 201, the gas inside the gas cylinder 2 can reach the delivery pipe 703 through the conduit 202 and then be sprayed out, so as to realize the fire extinguishing operation. Since the delivery pipe 703 passes through the center of the winding wheel 702 and is rotatably connected to the conduit 202, there is no need to pull the delivery pipe 703 before connecting it to the conduit 202 when in use.

At the same time, when replacing or fixing, the clamping plate 4 is rotated to get closer to the gas cylinder 2, so that the clamping plate 4 rotates and drives the connecting ring 401 to rotate, so that the stopper 402 rotates accordingly. The stopper 402 squeezes the inclined surface of the sliding block 301, so that the sliding block 301 is squeezed and moved to the inside of the installation frame 3. At the same time, when the stopper 402 rotates to the other side of the sliding block 301, the squeezing of the sliding block 301 is released, and then under the action of the torsion spring 502, the gear rod 501 rotates, and then the gear rack 302 drives the sliding block 301 to move in the opposite direction and reach the outside of the installation frame 3, thereby blocking the stopper 402 to prevent it from moving in the opposite direction, and the clamping piece 6 can be further driven by rotating the squeezing bolt 601, thereby further squeezing the gas cylinder 2 to keep it fixed.
