Description

Extinguisher to easily remove safety device.

FIELD OF THE INVENTION The present invention relates to a fire extinguisher in which a safeguard device is easily removed, and more particularly, to a fire extinguisher in which a safety device for easily removing a safeguard device and effectively suppressing fire when a fire occurs is easily removed.

Fire extinguishers are devices that can transport fire extinguishers to fire by using the effects of cooling or air shutoffs of the fire extinguisher in the early stages of the fire.

FIG. 1 is a cross-sectional view of a conventional fire extinguisher, and a general structure and problems of the fire extinguisher will be described with reference to FIG.

The fire extinguisher includes a main body 80 for storing an extinguishing agent, a discharge pipe 42 for transferring the extinguishing agent to the outside and located inside the main body 80, a lower handle 20 fixed to the upper portion of the extinguisher main body 80, The rotary shaft 70 rotatable in the direction of the lower handle is positioned on the upper handle 10 and the discharge pipe 42 so as to prevent the excretion of the extinguishing agent from being normally blown out. When pressed by the rotation of the upper handle, A hose for supporting the injection of the extinguishing agent into the correct position when the extinguishing agent in the extinguisher body is ejected by the pushing pin and a handle are generally pressed against the extinguisher due to a mistake, And a safety pin 30 located in a through hole 31 passing through the upper handle 10 and the lower handle 20 to prevent the release of the extinguishing agent.

The safety pin serves to fix the upper handle 10 so as not to rotate downward in the direction of the lower handle 20. When the user unintentionally grasps the upper handle 10 and the lower handle 20 in an emergency situation at the fire scene The upper handle 10 presses the safety pin 30 so that a large shearing force is transmitted to the safety pin so that the safety pin is not pulled out. That is, in the conventional fire extinguisher, the user can not remove the safety pin quickly, and the fire can not be suppressed in the early stage, so that the fire is spread to a large fire.

Korean Patent Registration No. 10-1444688 relates to a fire extinguisher having a safety handle and will be described with reference to FIG.

2 is a cross-sectional view of a safety handle for reducing the applied shear force of the safety pin. The safety pin 30 is inserted into the through hole 55 through which the support pin 50 provided on the rotatable hinge shaft 60 passing through the upper handle 10 passes through the lower handle 20 and the support pin 50 . The support pin 50 which is completely fixed by the safety pin 30 serves to support the upper handle 10 so as to prevent the lower handle 20 from rotating downward in the direction of the lower handle 20. Thus, when the user presses the upper handle 10 and the lower handle 20 The pressure of the upper handle 10 is not directly applied to the safety pin 30 even if the safety pin 30 is removed to suppress the fire at this time. The shear force can be removed with a small force.

However, in the conventional technique as described above, since the support pin 55 exerts a concentrated load on the center of the safety pin 30, the safety pin is still pressed against the safety pin, so that the safety pin can not be easily removed in an emergency.

Specific features and advantages of the present invention will be described in detail below with reference to the accompanying drawings. The detailed description of the functions and configurations of the present invention will be omitted if it is determined that the gist of the present invention may be unnecessarily blurred.

FIELD OF THE INVENTION The present invention relates to a fire extinguisher in which a safeguard device is easily removed, and more particularly, to a fire extinguisher in which a safety device for easily removing a safeguard device and effectively suppressing fire when a fire occurs is easily removed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a view showing the construction of a fire extinguisher in which a safety device using a fixing block according to the present invention is easily removed, FIG. 4 is a perspective view of a fire extinguisher, Fig. 5 is a partially enlarged cross-sectional view showing in detail the operation of the handle after the safety pin of the fire extinguisher, in which the safety device using the fixing block according to the present invention is easily removed, is removed.

As shown in FIGS. 3 to 5, the fire extinguisher which can easily remove the safety device according to the present invention includes a fire extinguisher body 800 to be filled with fire extinguishing agent, A lower handle 200 located at the upper portion of the main body 800 and a rotary shaft 700 penetrating the lower handle 200. The lower portion of the lower portion of the main body 800 is connected to the lower portion of the main body 800, The upper handle 100 is provided at an upper portion of the discharge pipe 420 so as to block the discharge pipe 420 and prevent the discharge of the extinguishing agent. A push pin 400 for ejecting the extinguishing agent through the gap generated when the pushpin 400 is pressed in the direction of the push pin 400 and a hose 900, and an upper handle (100) A fixing block 330 which is attached to the lower handle 200 and is in contact with the rotation guide pin 510 and a lower handle 200 which is attached to the lower handle 200. The rotation guide pin 510 is connected to the first hinge shaft 610, And a safety pin 310 which is positioned in the first through hole of the rotation guide pin 510 and circumscribes and fixes the rotation guide pin 510. [

The safety device of the fire extinguisher is composed of a rotation guide pin 510, a safety pin 310 and a fixing block 330.

The fixing block 330 attached to the lower knob 200 prevents the rotation guide pin 510 from protruding out of the lower knob 200, and in a preferred embodiment slightly tilts inward. If the rotation guide pin 510 is in a vertical state from the surface of the lower knob 200, even if the upper knob 100 is pressed, only the force in the vertical direction is received, so that the sliding movement of the upper knob 100 is difficult. The rotation guide pin 510 is guided to be slid in the horizontal direction by maintaining the slant at a constant slope.

The safety pin 310 is inserted into the first through hole 600 penetrated through the lower handle 200 and secured to the rotation guide pin 510 which is tilted by the fixing block 330 so as to be circumscribed, The rotation guide pin 510 is not caught by the safety pin 310 so that the upper grip 100 is rotated to prevent the pressing pin 400 from being pressed.

Since the rotation guide pin 510 is fixed even if the upper handle 100 is pressed, the safety pin 310 can be easily removed because the safety pin 310 does not apply a shearing force.

When the safety pin 310 is removed to use a fire extinguisher, the rotation guide pin 510 is slidable in a tilted direction. When the user grasps the upper grip 100 and the lower grip 200, The upper handle 100 is lowered in the direction of the lower handle 200 and the presser pin 400 is pressed to eject the extinguishing agent.

Compared with the conventional fire extinguisher equipped with the conventional safety pin, when the safety pin 310 is removed while the upper and lower grips 100 and 200 are being held, a load is generated only at the center of the safety pin 310, A smaller shearing force is generated, and the safety pin 310 can be easily removed.

FIG. 6 is a view illustrating a configuration of a fire extinguisher in which a safety device using a rotating block according to another embodiment of the present invention is easily removed. FIG. 7 is a perspective view illustrating a safety device using a rotating block according to another embodiment of the present invention. FIG. 8 is a partial enlarged cross-sectional view showing a handle portion coupled with a safety pin of a fire extinguisher in detail; FIG. 8 is a detail enlarged cross-sectional view illustrating a handle portion after a safety pin of a fire extinguisher, Fig.

6 to 8, a fire extinguisher in which a safety device according to another embodiment of the present invention is easily removed includes a fire extinguisher body 800 to be filled with fire extinguishing agent, A discharge pipe 420 which is a transfer passage for discharging the extinguishing agent to the outside and a lower handle 200 located at an upper portion of the main body 800 and a rotary shaft 700 passing through the lower handle 200 The upper handle 100 is provided at an upper portion of the discharge pipe 420 to block the discharge pipe 420 and prevent the discharge of the extinguishing agent. A push pin 400 for ejecting the extinguishing agent through a gap generated when the push button 400 is pushed in the direction of the discharge pipe 420 by rotation, A hose 900 for assisting the upper handle, A rotation guide pin 510 connected to the second hinge shaft 620 installed to penetrate the first hinge shaft 620 and rotated and connected to the third hinge shaft 630 installed through the lower handle 200, And a safety pin 310 which is located in the second through hole 640 of the lower handle 200 and is fixed to the rotary block 320 in a circumscribed state .

The safety device of the fire extinguisher includes a rotation guide pin 510, a safety pin 310 and a rotation block 320. The rotation guide pin 510 surrounds the rotation block 320 and the rotation block 320 is a safety pin 310).

The third hinge shaft 630 connected with the rotation block 320 and the second through hole 640 through which the safety pin 310 is inserted are positioned such that the axes are parallel to each other at the same height from the lower knob 200 The second hinge shaft 620 of the rotation guide pin 510 is located at a position vertically extending between the third hinge shaft 630 and the second through hole 640.

The rotation guide pin 510 connected to the second hinge shaft 620 is perpendicular to the surface of the lower handle 200 and is positioned at the extended position between the third hinge shaft and the second through hole 640. At this time, the rotation guide pin 510 is out of contact with the crushed part in the upper center of the rotation block 320 and can not move, and acts only in the vertical direction from the surface of the lower knob 200.

Accordingly, when the user holds the upper grip 100 and the lower grip 200 while the safety pin 310 is not removed, the rotation guide pin 510 receives a force from the lower grip 200 in a vertical state The upper handle 100 can not press the push pin 400 and the fire extinguishing agent is not sprayed.

It is preferable that the front and back sides of the rotation block 320 are formed so as to be higher than the center so that the rotation guide pin 510 receives the force only in the vertical direction and can be safely positioned at the center. That is, the rotation guide pin 510 is placed on the concave portion of the center portion.

Even if the user touches the upper handle 100 without removing the safety pin 310, since the safety pin 310 does not have a shearing force, the user can easily remove the safety pin in an emergency.

When the safety pin 310 is removed to use a fire extinguisher and the user grips the upper handle 100 and the lower handle 200, the rotation block 320 fixed by the safety pin 310 is moved downward And the rotation guide pin 510, which is circumscribed and fixed to the rotation block 320, is tilted along the rotation direction of the rotation block 320, and the force is transmitted in the horizontal direction to be slid. As a result, the upper knob 100 is rotated downward in the direction of the lower knob 200 to press the push pin 400, thereby extinguishing the extinguishing agent.

Accordingly, when the safety pin 310 is removed, the rotation block 320 rotates to rotate the rotation guide pin 510 in a vertical direction And is rotated in the horizontal direction.

When the safety pin 310 is removed while the upper and lower grips 100 and 200 are being held, the concentrated load generated by the rotation guide pin 510 is transmitted to the rotation block 320, The safety pin 310 can be easily removed because the shearing force can be reduced.

3 to 5 differs from the embodiment shown in Figs. 3 to 5 in that the vertical force is exerted because the direction of the force exerts only on the rotation guide pin 510, but the embodiment shown in Figs. The rotation guide pin 510 is tilted forward after a horizontal force acts on the rotation guide pin 510 so that the direction of the force acting on the rotation guide pin 510 can be moved toward the front end of the rotation block 320.

FIG. 9 is a view illustrating a configuration of a fire extinguisher in which a safety device using a safety handle is easily removed according to another embodiment of the present invention. FIG. 10 is a side view of a safety device using a safety handle according to another embodiment of the present invention. FIG. 11 is a partially enlarged cross-sectional view illustrating in detail a safety release state of a fire extinguisher in which a safety device using a safety handle according to another embodiment of the present invention is easily removed. FIG.

As shown in FIGS. 9 to 11, the fire extinguisher in which the safety device according to another embodiment of the present invention is easily removed is generally used for a small fire extinguisher of 1.5 kg or less, A discharge pipe 420 which is located inside the main body 800 and is a moving passage for discharging the extinguishing agent to the outside and a lower handle 200 located at an upper portion of the main body 800, An upper handle 100 having a rotary shaft 700 penetrating through the lower handle 200 and capable of rotating downward in the direction of the lower handle 200 and an upper handle 100 positioned above the discharge tube 420, A push pin 400 for blocking the ejection of the extinguishing agent and ejecting the extinguishing agent through the gap generated when the upper handle 100 is pushed toward the discharge pipe 420 by the rotation of the upper handle 100, (Not shown) A fixed guide pin 500 attached to the upper handle 100 to move along the rotational direction of the upper handle 100 and a hinge 900 attached to the lower handle 200 through the hinge 900. [ And a safety handle 300 connected to the fourth hinge shaft 650 and rotatable upward in the direction of the lower handle 200 and external to the fixed guide pin 500.

The safety device for the fire extinguisher is composed of a safety handle 300 and a fixed guide pin 500.

That is, unlike the embodiment of FIGS. 3 to 8, there is a large difference that no safety pin is formed.

The safety handle 300 is characterized in that the safety handle 300 is composed of a short engaging portion that is in contact with the fixed guide pin 500 on both sides with respect to the fourth hinge shaft 650 and a long handle portion that can be held by the user.

When the upper grip 100 and the lower grip 200 are only gripped without applying a force to the safety grip 300, the stationary guide pin 500 is fixed by the engagement portion of the safety grip 300, Can not be rotated downward in the direction of the lower knob 200, so that the presser pin 400 can not be pushed and the fire extinguishing agent is not sprayed.

When the user grips the safety handle 300 to use the fire extinguisher, the safety handle 300 is inserted into the lower handle 200 while being rotated upward in the direction of the lower handle 200, When the lower handle 200 is rotated in the lower direction, the stationary guide pin 500 attached to the upper handle 100 is inserted into the guide groove 301 formed in the safety handle 300, 400) and the fire extinguishing agent is sprayed.

In addition, in the case of a conventional fire extinguisher having a safety pin, compared with the problem that the safety pin was not removed due to a large shear force when the handle was caught and the fire was not extinguished in the early stage, when the user presses the upper handle 100 and the lower handle The fire extinguishing agent can be sprayed simply by grabbing the safety handle 300 and the upper handle 100 by spreading a hand held in a state in which the fire extinguisher 200 is held.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as a limitation of the scope of the present invention. Or modify it. The scope of the invention should, therefore, be construed in light of the claims set forth to cover many of such variations.
