UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of fire extinguisher of convenient hand to solve the problems raised in the above background.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of fire extinguisher of convenient hand, including fire extinguisher bottle body, the fire extinguisher bottle body top end is fixedly installed with sealing valve, the sealing valve side is communicated with spout, the sealing valve top end is fixedly installed with pressure gauge, the sealing valve top end is fixedly installed with press button, the press button bottom end is fixedly installed with hand strap, the press button is opened with through slot corresponding hand strap, the hand strap passes through through slot, the hand strap is slidably connected with through slot, the press button is fixedly connected with installation limit frame close to through slot side, the limit frame top end is fixedly connected with support frame, the support frame is rotatably connected with round shaft, the round shaft is fixedly connected with metal plate, the round shaft side is opened with first insertion hole, the limit frame is opened with second insertion hole corresponding first insertion hole, first insertion hole and second insertion hole are inserted with bolt in common.

[0006] Preferably, the hand strap is made of nylon material.

[0007] Preferably, the side of the metal plate close to the hand strap is serrated, and the metal plate is attached to the top end of the hand strap.

[0008] Preferably, when the first insertion hole of the circular shaft corresponds to the second insertion hole of the limiting frame, the metal plate is in an inclined state.

[0009] Preferably, the limiting frame is a frame-shaped structure, and the hand strap is slidably connected to the limiting frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by wrapping the hand holding the fire extinguisher with a hand strap that can be quickly adjusted to tighten or loosen, the fit between the hand and the handle is enhanced, thereby increasing the stability of holding and lifting, reducing the risk of the fire extinguisher slipping from the hand during the holding process, and the structure is simple and easy to use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5This utility model provides a technical solution: a portable fire extinguisher, including a fire extinguisher bottle 1, a sealing valve 2 fixedly installed at the top of the fire extinguisher bottle 1, a nozzle 3 connected to one side of the sealing valve 2, a pressure gauge 4 fixedly installed on the sealing valve 2, a pressure handle 5 fixedly installed at the top of the sealing valve 2, a hand strap 6 fixedly installed at the bottom of the pressure handle 5, a through groove 7 opened on the pressure handle 5 corresponding to the hand strap 6, the hand strap 6 passing through the through groove 7, the hand strap 6 and the through groove 7 being slidably connected, a mounting limit frame 8 fixedly connected to the side of the pressure handle 5 near the through groove 7, a support frame 9 fixedly connected to the top of the limit frame 8, a round shaft 10 rotatably connected to the support frame 9, a metal plate 11 fixedly connected to the round shaft 10, a first insertion hole 12 opened on one side of the round shaft 10, a second insertion hole 13 opened on the limit frame 8 corresponding to the first insertion hole 12, and a pin 14 being inserted into both the first insertion hole 12 and the second insertion hole 13.

[0019] The wrist strap 6 is made of nylon material, which makes it easy to wrap the palm with the high-strength and unbreakable wrist strap 6. The side of the metal plate 11 near the wrist strap 6 is serrated. The metal plate 11 fits into the top of the wrist strap 6. When the first insertion hole 12 of the round shaft 10 corresponds to the second insertion hole 13 of the limiting frame 8, the metal plate 11 is in an inclined state, which makes it easy for the inclined serrated metal plate 11 to limit the wrist strap 6. The limiting frame 8 has a frame structure design. The wrist strap 6 is slidably connected to the limiting frame 8, which makes it easy for the limiting frame 8 to limit the wrist strap 6.

[0020] Specifically, when using this utility model, after removing the safety pin of the fire extinguisher, insert your left hand into the gap between the hand strap 6 and the pressure handle 5, and pull the hand strap 6. The hand strap 6 moves towards the limiting frame 8 through the through groove 7 opened in the pressure handle 5. Since the serrated metal plate 11 is attached to the surface of the nylon hand strap 6, when the hand strap 6 retracts, the serrated metal plate 11 squeezes and blocks the surface of the hand strap 6, fixing the position of the hand strap 6. At this time, the hand strap 6 wraps around the left hand, increasing the stability of the grip. After use, pull the pin 14 out from the first insertion hole 12 and the second insertion hole 13. At this time, the round shaft 10, which is no longer positioned by the pin 14, is in a movable state. The movable round shaft 10 then drives the metal plate 11 to move. At this time, the movable metal plate 11 can hardly squeeze and block the hand strap 6, so the left hand can be pulled out.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
