Problems solved by technology

[0004]According to the above-mentioned patent, the patent presses down the clamp, and the stopper will be sandwiched between the top block and the limit block, thereby realizing the locking and pressing However, when the lock is unlocked, the stopper will be blocked by the top block and cannot return to the original state normally, and the patent directly presses down the upper plate, which may easily cause damage to the upper plate, so that it cannot Press to the final position, therefore, there is currently a need for a self-locking device that can self-lock the pressing handle and can both automatically unlock the locked state and manually unlock the locked state

Embodiment 1

[0040] like Figure 1 to Figure 10 As shown, the fire extinguisher with the handle self-locking function of this embodiment includes a fire extinguisher body 1, and the fire extinguisher body 1 includes a cylinder body 1a and a cylinder cover 1b, and the cylinder cover 1b is connected to the cylinder body 1a. A grip 1d fixed thereon and a pressing handle 1e whose one end is hinged to the fixed end of the grip 1d, and between the grip 1d and pressing The self-locking device 2 for locking it, the self-locking device 2 includes a movable sleeve 2a arranged on the handle 1d, a clip 2b arranged in the movable sleeve 2a, and a joint 2b arranged at the connection between the handle 1d and the cylinder cover 1b. The automatic locking mechanism 2c, the movable sleeve 2a can move horizontally along its length direction on the handle 1d, the handle 1d is provided with a bar-shaped opening for the movable sleeve 2a to move, and the clip 2b can be moved on the movable sleeve 2a. It moves ...

Embodiment 2

[0058] Compared with Example 1, as Image 6 and Figure 7 As shown, in this embodiment, the toggle member 4d includes a toggle rod 4d2 with a spherical toggle head 4d1 at the end, the diameter of the spherical toggle head 4d1 is larger than the diameter of the toggle rod 4d2, and the free end of the toggle rod 4d2 is coaxial and threaded Connected to the bottom of the cylinder 2b1, the lower surface of the handle 1d is also fixedly provided with a sheath 4e that is sleeved on the lever 4d2, and the sheath 4e is provided with a supply lever 4d2 along the moving direction of the movable sleeve 2a. The moving dial, and the spherical dial 4d1 passes through the dial and is located on the outer side of the sheath 4e. When the operator holds the handle 1d, the operator's index finger is between the spherical dial 4d1 and the cylinder cover 1b. When the lever 1e is pressed down, the lever 4d2 protrudes from the lever opening. When it is necessary to release the locked state of the c...

Abstract

The invention relates to the field of fire extinguishers, in particular to a fire extinguisher with a handle self-locking function, which comprises a fire extinguisher body, the fire extinguisher body comprises a cylinder and a cylinder cover, the cylinder cover is connected with a spray pipe, a grip and a pressing handle, and a self-locking device is further arranged between the grip and the pressing handle. The self-locking device comprises a movable sleeve, a clamping piece and an automatic locking mechanism, the movable sleeve can horizontally move on the grip in the length direction of the grip, a strip-shaped opening allowing the movable sleeve to move is formed in the grip, the clamping piece can move in the movable sleeve in the axis direction of the movable sleeve, and a linkage pressing mechanism is further arranged between the grip and the pressing handle. By pressing the pressing handle to drive the linkage pressing mechanism to move the clamping piece downwards and matching the clamping piece with the automatic locking mechanism, locking of the clamping piece by the automatic locking mechanism is achieved, so that locking of the pressing handle is achieved, using force is reduced, and operation is facilitated.

Description

technical field [0001] The invention relates to the field of fire extinguishers, in particular to a fire extinguisher with a handle self-locking function. Background technique [0002] Fire is a kind of disaster that is not limited by time and space and occurs with high frequency. This kind of disaster occurs with the history of human use of fire, so the fire protection work to prevent and control fire also emerges as the times require. With the development and the progress of the times, firefighting technology has also been continuously developed and gradually improved. In the process of using traditional fire extinguishers, the fire hydrant needs to be opened first, and then the handle is pressed. In the process of extinguishing the fire, the handle needs to be pressed until The fire source is extinguished, but due to the heavy weight of the fire extinguisher, it will consume too much physical strength to keep pressing the handle. The phenomenon of physical overdraft occu...
