Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting equipment, in particular to a hanging type fire extinguisher. Background Art

[0002] In factory buildings, fire prevention measures must be taken due to the large number of electrical equipment, and most of these measures involve the placement of hanging fire extinguishers in advance. After the equipment is moved, some of the original hanging fire extinguishers need to be removed and then re-hanged. This requires operations such as climbing, which is very troublesome. Summary of the invention

[0003] The utility model aims at the deficiencies of the prior art and provides a hanging fire extinguisher, which can change the angle of the hanging fire extinguisher without changing its original position, thereby avoiding the problem of needing to disassemble and reassemble the device after changing its position.

[0004] In order to solve the above technical problems, the utility model is solved through the following technical solutions: a suspended fire extinguisher, comprising a fixed component, a rotating ring, a connecting ring, a hook rod and a fire extinguisher body, the fixed component is provided with an annular groove, the rotating ring is embedded in the annular groove and rotatably connected thereto, the rotating ring is provided with a limit ring at one end embedded in the annular groove, an annular tension spring is provided inside the rotating ring, the other end of the tension spring is connected to the connecting ring, the inner ring of the connecting ring is symmetrically provided with two support plates, the support plates are provided with holes, the fire extinguisher body is provided with two symmetrical protrusions, the protrusions pass through the holes and are rotatably connected to the support plates, the top of the fire extinguisher body close to the fixed component end is hemispherical, the fixed component is provided with a corresponding groove at the end close to the fire extinguisher body, and the fire extinguisher body is provided with a nozzle and a hanging buckle at the end away from the fixed component. With this structure, the fire extinguisher is hung on the top of the factory building. When in use, the existing hook rod is used to hook the hook on the fire extinguisher body and pull it downward. The tension spring is stretched and rotated to rotate the rotating ring, that is, the fire extinguisher body rotates. Then the hook is hooked and the hook rod is swung to make the fire extinguisher swing left and right. The hook rod is loosened, and the connecting ring presses the fixed component under the action of the tension spring. Under the action of the friction force of the contact surface, it no longer rotates. Similarly, the hemispherical part of the fire extinguisher body is retracted into the groove on the fixed component and positioned under the action of friction.

[0005] In the above technical solution, preferably, the groove and the hemispherical end of the fire extinguisher body are provided with an anti-skid layer. With this structure, after the tension spring contracts, the hemispherical end of the fire extinguisher body is pressed tightly in the groove, and the anti-skid layer increases the friction, so that it is not easy to move after pressing.

[0006] In the above technical solution, preferably, the surface of the connecting ring in contact with the fixing component is provided with an anti-skid layer. With this structure, after the tension spring contracts, the anti-skid layer increases the friction force, and displacement is not easy to occur after compression.

[0007] In the above technical solution, preferably, the top of the fixing component is provided with a hook for fixing.

[0008] In the above technical solution, preferably, the hook is in the shape of a semicircular ring.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the hanging fire extinguisher uses a hook rod to hook the hook buckle and pull it down, then rotates and adjusts the angle as needed, releases the hook rod, and the position of the fire extinguisher body is fixed under the action of friction, which solves the problem of needing to disassemble and reassemble the fire extinguisher after changing the position of the equipment in the factory.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 4A hanging fire extinguisher includes a fixed component 1, a rotating ring 2, a connecting ring 3, a hook rod and a fire extinguisher body 4. The fixed component 1 is provided with an annular groove, the rotating ring 2 is embedded in the annular groove, and a limit ring 8 is provided at one end of the rotating ring 2 embedded in the annular groove. An annular tension spring 7 is provided inside the rotating ring 2, and the other end of the tension spring 7 is connected to the connecting ring 3. The inner circle of the connecting ring 3 is symmetrically provided with two support plates 5, and the support plates 5 are provided with holes. The fire extinguisher body 4 is provided with two symmetrical protrusions 6, which pass through the holes and are rotatably connected with the support plates 5. The top of the fire extinguisher body 4 near the fixed component 1 is hemispherical, and the fixed component 1 is provided with a corresponding groove 9 at the end of the fire extinguisher body 4 near the fixed component 1. The fire extinguisher body 4 is provided with a nozzle 10 and a hook 11 at the end away from the fixed component 1. The fire extinguisher is suspended on the top of the factory building. When in use, the existing hook rod is used to hook the hook on the fire extinguisher body and pull it down, the tension spring is stretched, and the rotating ring is rotated, that is, the fire extinguisher body rotates, and then the hook is hooked and the hook rod is swung to swing the fire extinguisher left and right. Loosen the hook rod, and the connecting ring presses the fixed part under the action of the tension spring, and no longer rotates under the action of the friction force of the contact surface. Similarly, the hemispherical part of the fire extinguisher body is retracted into the groove on the fixed part and positioned under the action of friction.

[0015] In this embodiment, the groove 9 and the hemispherical end of the fire extinguisher body 4 are provided with an anti-skid layer. After the tension spring contracts, the hemispherical end of the fire extinguisher body is pressed tightly in the groove, and the anti-skid layer increases the friction, so that it is not easy to move after pressing.

[0016] In this embodiment, the surface of the connecting ring 3 in contact with the fixing component 1 is provided with an anti-skid layer. After the tension spring contracts, the anti-skid layer increases the friction force, and it is not easy to move after being pressed.

[0017] In this embodiment, a hook 12 for fixing is provided at the top of the fixing component 1 .

[0018] In this embodiment, the hook 11 is in the shape of a semicircular ring.

[0019] Compared with the prior art, the utility model uses a hook rod to hook the hook buckle and pull it down, then rotates and adjusts the angle as needed, releases the hook rod, and the position of the fire extinguisher body is fixed under the action of friction, thus solving the problem of needing to disassemble and reassemble the fire extinguisher after changing the position of the equipment in the factory.

[0020] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
