Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a handheld fire extinguisher. Background Technology

[0002] A fire extinguisher is a manually operated device that uses internal pressure to spray out an extinguishing agent to put out a fire. Water-based fire extinguishers include water extinguishers and foam extinguishers. Dry powder extinguishers include sodium bicarbonate dry powder extinguishers (also called Class BC dry powder extinguishers) and sodium bicarbonate dry powder extinguishers (also called Class ABC dry powder extinguishers). Foam extinguishers are mainly used to extinguish Class B fires, such as initial fires involving gasoline, kerosene, diesel, benzene, toluene, xylene, vegetable oil, and animal fats. They can also be used for initial fires involving solid materials such as wood, bamboo, paper, and cotton / linen fabrics.

[0003] Existing handheld fire extinguishers have some shortcomings in use. Traditional nozzles are directly connected to the fire extinguisher handle interface, resulting in relatively poor sealing at the joint and a risk of extinguishing agent leakage. This not only affects the fire extinguishing needs but also poses a risk to personnel and reduces the stable use of the fire extinguisher. Therefore, a handheld fire extinguisher is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a handheld fire extinguisher to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a handheld fire extinguisher, including a fire extinguisher barrel, a fire extinguisher handle fixedly installed at the upper end of the fire extinguisher barrel and a safety bolt installed inside the fire extinguisher handle, a pressure gauge installed on the outside of the fire extinguisher handle, a nozzle installed on one side of the fire extinguisher handle and an atomizing nozzle fixedly connected to one end of the nozzle, and a limit structure installed on the outer wall of the nozzle on the outside of the fire extinguisher barrel;

[0006] A sealing structure is provided between the fire extinguisher handle and the nozzle. The sealing structure includes a handle connector fixedly installed on one end of the fire extinguisher handle. A sealing groove is opened inside the handle connector. A rubber sealing gasket is fixedly installed inside the sealing groove. A sealing ring is provided on the outside of the rubber sealing gasket. A sealing snap ring is fixedly installed at one end of the nozzle. A first sealing cover plate and a second sealing cover plate are fitted at the gap between the sealing snap ring and the handle connector.

[0007] As a preferred embodiment of the above technical solution, the rubber sealing gasket and sealing ring are adapted to the size of the sealing groove, the sealing snap ring is inserted into the sealing groove in a corresponding position, and the nozzle and pressure handle connecting pipe are adapted to each other.

[0008] As a preferred embodiment of the above technical solution, the first sealing cover and the second sealing cover are adapted to the diameter of the pressure handle tube, and the first sealing cover and the second sealing cover are respectively fixedly installed with limiting blocks of the same size at both ends, and bolts are inserted into the two sets of limiting blocks.

[0009] As a preferred embodiment of the above technical solution, a sealing gasket is fitted on the outer wall of the bolt, the sealing gasket is in contact with the limiting blocks at both ends of the first sealing cover, a locking nut is threaded on the outer wall of the bolt, auxiliary handles are symmetrically fixedly connected to the outer wall of the fire extinguisher barrel, and an installation collar is fixedly provided on the outer wall of the fire extinguisher barrel.

[0010] As a preferred embodiment of the above technical solution, a placement box is fixedly provided on the outer wall of the mounting collar, a dust cap of a suitable size is fitted on one end of the atomizing nozzle, and the limiting structure includes a limiting frame fixedly installed on the outer wall of the mounting collar.

[0011] As a preferred embodiment of the above technical solution, the outer end of the limiting frame is provided with a slot, and multiple sets of limiting rods are symmetrically arranged inside the limiting frame, with limiting springs sleeved on the outer wall of the limiting rods. One end of each of the two sets of limiting springs is connected to two limiting clamps, and the limiting clamps are adapted to the diameter of the nozzle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model device is equipped with a sealing structure. When one end of the nozzle is connected to the pressure handle connector, the sealing ring and rubber sealing gasket are squeezed to make the nozzle and pressure handle connector relatively sealed. The first sealing cover plate and the second sealing cover plate are fitted and fixed together. Then, the bolts and locking nuts cooperate to limit the position, which facilitates the pre-tightening of the first sealing cover plate and the second sealing cover plate to effectively seal the gap. This helps to improve the sealing performance of the connection between the nozzle and the pressure handle connector, avoid problems such as fire extinguishing agent leakage caused by poor sealing at the interface, and improve the stability of the fire extinguisher in use.

[0014] 2. This utility model device is equipped with a limiting structure. By setting a limiting frame, after the fire extinguisher is used, the nozzle of the fire extinguisher is placed inside the limiting frame. Under the cooperation of the limiting spring, the limiting clamp plate squeezes the nozzle to lock and fix it. At the same time, an anti-slip pad is set on the outer wall of the limiting clamp plate to stabilize and limit the outer wall of the nozzle. This helps to limit and fix the nozzle after use, avoids problems such as tangling and knotting caused by the nozzle shaking back and forth during the handling of the fire extinguisher, and facilitates the protection of the nozzle.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown, this embodiment provides a handheld fire extinguisher, including a fire extinguisher barrel 1, a fire extinguisher handle 3 fixedly installed at the upper end of the fire extinguisher barrel 1, and a safety bolt installed inside the fire extinguisher handle 3, a pressure gauge installed on the outside of the fire extinguisher handle 3, a nozzle 2 installed on one side of the fire extinguisher handle 3, and an atomizing nozzle 8 fixedly connected to one end of the nozzle 2, and a limiting structure 10 is provided on the outer wall of the nozzle 2 located on the outside of the fire extinguisher barrel 1;

[0025] A sealing structure 5 is provided between the fire extinguisher handle 3 and the nozzle 2. The sealing structure 5 includes a handle connector 51 fixedly installed on one end of the fire extinguisher handle 3. A sealing groove 52 is provided inside the handle connector 51. A rubber sealing gasket 53 is fixedly installed inside the sealing groove 52. A sealing ring 54 is provided on the outside of the rubber sealing gasket 53. A sealing snap ring 21 is fixedly installed on one end of the nozzle 2. A first sealing cover plate 55 and a second sealing cover plate 56 are fitted at the gap between the sealing snap ring 21 and the handle connector 51.

[0026] like Figures 3 to 4 As shown, the rubber sealing gasket 53 and sealing ring 54 are adapted to the size of the sealing groove 52, the sealing snap ring 21 is inserted into the sealing groove 52, the nozzle 2 and the pressure handle connector 51 are adapted to the size, the first sealing cover plate 55 and the second sealing cover plate 56 are adapted to the diameter of the pressure handle connector 51, the first sealing cover plate 55 and the second sealing cover plate 56 are respectively fixedly installed with limit blocks 57 of the same size at both ends, the two sets of limit blocks 57 are each inserted with bolts 58, the outer wall of the bolts 58 is fitted with sealing gaskets 581, the sealing gaskets 581 are in contact with the limit blocks 57 at both ends of the first sealing cover plate 55, the outer wall of the bolts 58 is threaded with locking nuts 59, the outer wall of the fire extinguisher barrel 1 is symmetrically fixedly connected with auxiliary handles 4, and the outer wall of the fire extinguisher barrel 1 is fixedly provided with installation collars 6.

[0027] By squeezing the sealing ring 54 and the rubber sealing gasket 53 when one end of the nozzle 2 is connected to the pressure handle connector 51, the nozzle 2 and the pressure handle connector 51 are relatively sealed. Finally, the first sealing cover plate 55 and the second sealing cover plate 56 are fitted and fixed together, and then the bolts 58 and the locking nut 59 are used to limit the movement, so that the first sealing cover plate 55 and the second sealing cover plate 56 are pre-tightened to effectively seal the gap, thereby improving the sealing performance of the connection between the nozzle 2 and the pressure handle connector 51.

[0028] A placement box 7 is fixedly installed on the outer wall of the mounting collar 6. A dust cap 9 of a suitable size is fitted on one end of the atomizing nozzle 8. The limiting structure 10 includes a limiting frame 101 fixedly installed on the outer wall of the mounting collar 6. A slot 102 is opened at the outer end of the limiting frame 101. Multiple sets of limiting rods 103 are symmetrically arranged inside the limiting frame 101, and a limiting spring 104 is fitted on the outer wall of the limiting rod 103. Two sets of limiting springs 104 are respectively connected to two limiting clamps 105 at one end. The limiting clamps 105 are adapted to the diameter of the nozzle 2.

[0029] By setting up a dust cap 9 and a placement box 7, the dust cap 9 can be used to seal the atomizing nozzle 8 when the fire extinguisher is not in use, thus preventing pollution caused by exposure to air. When in use, it can simply be placed in the placement box 7. The limiting bracket 101 allows the fire extinguisher to be placed inside the limiting bracket 101 after use. With the cooperation of the limiting spring 104, the limiting clamp 105 can be driven to squeeze and lock the nozzle 2. At the same time, an anti-slip pad is provided on the outer wall of the limiting clamp 105 to stabilize and limit the outer wall of the nozzle 2.

[0030] The working principle and process of this utility model are as follows: When using a fire extinguisher, it needs to be assembled. One end of the nozzle 2 is connected to one end of the fire extinguisher handle 3 on the fire extinguisher body 1. The sealing ring 21 of the nozzle 2 is then connected and fixed to the sealing groove 52 in the handle connector 51. This causes the sealing ring 21 to squeeze the rubber sealing gasket 53 and sealing ring 54 in the sealing groove 52, thus filling the gaps for effective sealing. Finally, the first sealing cover plate 55 and the second sealing cover plate 56 are aligned and connected to the two sets of limiting blocks 57 by two bolts 58. Then, the two bolts 58 are tightened and fixed by the locking nut 59, thereby further sealing the joint and preventing problems such as leakage of extinguishing agent due to poor sealing at the connection of the nozzle 2 during use, which would affect the use of the fire extinguisher.

[0031] When using a fire extinguisher, the operator opens the dust cap 9 and places it inside the storage box 7. Then, the safety pin is pulled out, and the fire extinguisher handle 3 is manually pressed to spray the extinguishing agent from the atomizing nozzle 8 on the nozzle 2 to extinguish the flames. After the flames are extinguished, the nozzle 2 is squeezed into the slot 102 in the limiting bracket 101. Then, multiple sets of limiting rods 103 and limiting springs 104 work together to cause the outer wall of the nozzle 2 to press against the two limiting clamps 105 and move outward. When the nozzle 2 is fully squeezed in, it rebounds under the elastic force of the limiting spring 104, thus clamping and limiting the nozzle 2. When taking it out, it can be pulled out directly. The operation is simple and avoids problems such as the nozzle 2 shaking back and forth and getting tangled when the fire extinguisher is moved. Finally, the operator can carry it with the auxiliary handle 4.
