Description

Technical Field

[0001] The utility model discloses a fire extinguishing device, in particular to a portable fire fighting and extinguishing device. Background Art

[0002] There are various types of fire extinguishing devices. Among them, fire hydrants, fire pipelines, fire extinguishers and other fire fighting appliances can all be called fire extinguishing devices. In the prior art, fire extinguishers are generally more common. Fire hydrants and fire pipelines are generally used more in larger places or in the overall building. Fire extinguishers are the most common, and fire extinguisher boxes are provided in basic buildings to store fire extinguishers for standby.

[0003] Moreover, the size of the fire extinguisher can also be designed according to the usage and standby situations. Therefore, it is the most convenient type among fire extinguishing devices and is often used. In-vehicle fire extinguishers are a small and portable style. In the prior art, fire extinguishers are generally locked and restricted by bolts and safety pins. By pulling out the safety pin or bolt, the internal dry powder or other chemical substances can be pressed out for fire extinguishing. However, because of its convenience, it is often carried around. For example, in-vehicle fire extinguishers are jolted and transported around with the vehicle. Although the bolt connection is relatively tight, after long-term jolting and touching, there is still a risk of the bolt becoming loose. Therefore, there may be a situation of accidental pressing. In the prior art, there are methods to eliminate hidden dangers by changing the bolt restriction method and the valve switch, but this application still proposes another solution to make the bolt fall off but there will be no accidental pressing of the fire extinguisher. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a portable fire fighting and extinguishing device to solve the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: A portable fire fighting and extinguishing device includes a bottle body, a spray pipe and a pressing plate. A connecting part is arranged between the bottle body and the pressing plate. A bolt is arranged outside the connecting part. A support member for restricting the downward movement of the pressing plate is arranged between the pressing plate and the connecting part. A first spring is sleeved outside the support member. The pressing plate is provided with a through hole for the support member to pass through. A limiting component for restricting the support member is slidably connected to the pressing plate.

[0006] Preferably, the limiting component includes a limiting strip slidably connected to the pressing plate for blocking the support member. The pressing plate is provided with a guiding groove for the limiting strip to move. The pressing plate is provided with a second spring for pushing the limiting strip to reset.

[0007] Preferably, the tail of the limiting strip passes through the pressing plate. The limiting strip is elastically arranged, and the distance from the front end of the limiting strip to the through hole is relatively long.

[0008] Preferably, an opening for the restraining strip to pass through is provided at the tail of the pressing plate, and a blocking block for blocking the restraining strip and changing its moving path is provided on the opening.

[0009] Preferably, a connecting rope is connected to the end of the bolt, the other end of the connecting rope is connected to the end of the restraining strip, a restraining groove for accommodating the movement of the connecting rope and restricting its moving path is provided on the pressing plate, and a sliding groove for accommodating the movement of the connecting rope is provided at the upper end of the groove where the connecting part is embedded with the bolt.

[0010] Preferably, rollers for accommodating the winding of the connecting rope are provided on the end of the pressing plate and the sliding groove of the connecting part.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] After using this device, if it is placed in a vehicle or carried out, during transportation, due to bumps and shakes, the bolt may fall off. Since the restraining strip can only move horizontally and cannot move upward, the upward movement of the support member is blocked. The support member is blocked by the restraining strip and cannot move upward, so that the blocking of the support member restricts the downward movement of the pressing plate. In this way, even if the bolt falls off during transportation and shakes and bumps and squeezes the pressing plate, it will not cause accidental spraying, thus achieving a protective effect.

Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] A portable fire extinguishing device, as Figures 1-3 shown, includes a bottle body 1, a nozzle 2, and a pressing plate 3. A connecting portion 4 is provided between the bottle body 1 and the pressing plate 3. A pin 5 is provided outside the connecting portion 4. A support member 6 for restricting the downward movement of the pressing plate 3 is provided between the pressing plate 3 and the connecting portion 4. A first spring 7 is sleeved outside the support member 6. A through hole 8 for the support member 6 to pass through is provided on the pressing plate 3. A limiting component for restricting the support member 6 is slidably connected to the pressing plate 3. The limiting component includes a limiting strip 9 slidably connected to the pressing plate 3 for blocking the support member 6. A guiding groove 10 for the limiting strip 9 to move is provided on the pressing plate 3. In the prior art, when using a fire extinguisher, the pin 5 is pulled out and the pressing plate 3 is pressed to open the valve in the connecting portion 4, and chemical substances are sprayed out through the nozzle 2 to achieve the fire extinguishing effect. However, when the portable device is used in a vehicle or carried out, it often shakes or jolts. Therefore, the pin 5 may become loose and fall off due to shaking or collision during long-term carrying. As a result, the restriction on the pressing plate 3 is released, and it is very likely that the pressing plate 3 will be pressed down due to collision or accidental touch, and the chemical substances inside the spraying part will be affected. Therefore, it will affect the subsequent use and the storage location. After using this device, the support member 6 between the pressing plate 3 and the connecting portion 4 provides support, and the limiting strip 9 is slidably connected to the pressing plate 3 horizontally and cannot move upward. Therefore, under the mutual restriction of the support member 6, the pressing plate 3, and the limiting strip 9, the support member 6 cannot pass through the through hole 8, and the pressing plate 3 cannot move downward. In this way, even if the pin 5 becomes loose and the pressing plate 3 is collided or squeezed during transportation, the pressing plate 3 cannot be pressed, thus avoiding the occurrence of accidental spraying.

[0019] The tail of the limiting strip 9 passes through the pressing plate 3. The limiting strip 9 is elastically arranged, and the front end of the limiting strip 9 is far away from the perforation 8. The pressing plate 3 is provided with an opening 12 at the tail to accommodate the limiting strip 9 to pass through. The opening 12 is provided with a blocking block 13 for blocking the limiting strip 9 and changing the moving path. The pressing plate 3 is provided with a spring 11 for pushing the limiting strip 9 to reset. If the device is used normally, it only needs to slide the limiting strip 9 backward and compress the spring 11 to cancel the blocking of the perforation 8. After the blocking of the support member 6 is released, the pressing plate 3 can move downward. The spring 7 is pressed and compressed, and when the limiting strip 9 moves backward, the tail can pass through the opening 12 through the restriction of the blocking block 13. The end of the latch 5 is connected with a connecting rope 14, and the other end of the connecting rope 14 is connected to the end of the limiting strip 9. The pressing plate 3 is provided with a limiting groove 15 that accommodates the movement of the connecting rope 14 and limits the movement path of the connecting rope 14. The connecting part 4 is located at the upper end of the groove where the latch 5 is embedded, and a sliding groove 16 that accommodates the movement of the connecting rope 14 is provided. The end of the pressing plate 3 and the sliding groove 16 of the connecting part 4 are provided with a roller 17 that accommodates the winding of the connecting rope 14, and move downward so that the limiting groove 15 can be used to limit the movement of the connecting rope 14. The strip 9 is deformed and moved downward, pulling the connecting rope 14 at the same time, pushing the latch 5 out of the connecting portion 4 along the slide groove 16 and canceling the restriction on the pressure plate 3, and the connecting rope 14 continues to move along the restriction groove 15, limiting the movement path of the connecting rope 14 to ensure that when the connecting rope 14 is pulled downward, the latch 5 can be pushed out, and when the connecting rope 14 is pulled, the roller 17 can facilitate the movement of the connecting rope 14, reducing the restriction of friction, and finally when the restriction strip 9 continues to move downward, it can drive the pressure plate 3 to move downward, so that after the above arrangement, when the fire extinguisher needs to be used, Only by pushing the limit bar 9 backward, the latch 5 can be pulled to release the limit on the pressure plate 3, and the pressure plate 3 can be directly pressed down by moving downward, so as to achieve the effect of spraying along the nozzle 2 by using the deflated air. After the limit bar 9 is pulled back, the spring 1 7 and the spring 2 11 can drive the limit bar 9 and the pressure plate 3 to reset, and the connecting rope 14 is loosened, and the latch 5 can be pulled again to drive the connecting rope 14 to be embedded. On the contrary, when the limit bar 9 is not in use, it cannot be moved by simply shaking, and even if the latch 5 falls, the pressure plate 3 cannot be pressed, so as to achieve protection to avoid accidental touch. It is easy to use, the safety factor is improved, and the practicality is increased.
