Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and in particular to a portable fire extinguisher. Background Technology

[0002] Fire extinguishers are one of the most common fire-fighting equipment. Among them, portable fire extinguishers are a type of fire extinguisher that is placed or fixed on a mobile frame, making them easy to move and thus attracting widespread attention.

[0003] To prevent the fire extinguisher from shaking during movement, current portable fire extinguishers are usually secured to a mobile frame using clips (or clamps). However, in some scenarios, the mobile frame often cannot reach the fire scene, so the fire extinguisher needs to be removed for use in an emergency. The current portable fire extinguisher secured by clips takes a lot of time to remove, often causing the best opportunity to extinguish the fire to be missed.

[0004] Secondly, existing portable fire extinguishers are equipped with support legs on their mobile stands. These support legs are usually bent and are used to support the mobile stand when not in use. However, these bent support legs often affect the mobile stand's ability to pass through some obstacles (protruding parts or bumpy sections of the mobile path, the same below). In the context of a race against time to fight a fire, this can easily cause the fire extinguisher to tip over or people to fall.

[0005] In conclusion, existing portable fire extinguishers need to be improved so that they do not easily shake when moved and the mobile stand does not collide with road obstacles, and can be easily removed and used in emergencies. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable fire extinguisher, which aims to solve the problems mentioned in the background technology.

[0007] The technical solution of this utility model is implemented as follows: a portable fire extinguisher includes a mobile frame and a fire extinguisher placed on the mobile frame, wherein the mobile frame includes: The frame is equipped with wheels and has a support base for placing fire extinguishers; Limiting ring, fixed to the frame; A clamping device is provided on the frame; The clamping device includes a clamping plate that can move relative to the frame, a pressure block that is telescopically mounted on the support, and a lever structure that is connected between the pressure block and the clamping plate. When the fire extinguisher is placed on the support, the lever structure is controlled by the pressure block to drive the clamping plate to move closer to the limit ring.

[0008] By adopting the above technical solution: This invention features a pressing device on a movable frame. The pressing plate of the pressing device is controlled by a pressure block on the support base via a lever structure. When the fire extinguisher is placed on the pressure block of the support base, the fire extinguisher uses its own weight to drive the lever structure to move the pressing plate toward the limiting ring via the pressure block. Thus, the fire extinguisher can be fixed by the pressing plate and the limiting ring, preventing the fire extinguisher from shaking during movement.

[0009] Preferably, the lever structure includes: The lever plate is rotatably connected to the frame via a hinge shaft; The drive plate is slidably connected to the frame and can be raised by one end of the lever. The clamping plate and the frame form an active area for the drive plate to move, and the mating surfaces of the clamping plate and the drive plate are provided with mutually compatible protrusions and grooves. When the drive plate slides, the protrusion can enter or leave the groove; when the protrusion leaves the groove, the protrusion pushes up the clamping plate and drives the clamping plate to move closer to the limit ring.

[0010] Preferably, the clamping plate comprises: The clamping plate has a limiting sliding post on the side near the frame. The first limiting spring is fixedly connected to the limiting slide pin; The frame is provided with a limiting groove for the insertion of the limiting slide column, and the other end of the first limiting spring is fixedly connected to the limiting groove.

[0012] By adopting the above technical solution: The movement of the pressing plate in this invention is controlled by the lifting and lowering of the drive plate. The drive plate is provided with a protrusion. When the drive plate moves up and down, the protrusion will leave or enter the groove. When the protrusion leaves the groove, it will push the pressing plate outward, thereby causing the pressing plate to move closer to the limiting ring.

[0013] Preferably, the frame is also equipped with a self-locking plug that slides and rises, the self-locking plug being able to fall down after the pressing plate moves close to the limiting stop ring, and is used to restrict the movement of the pressing plate.

[0014] By adopting the above technical solution: When the clamping plate approaches the limiting ring, a gap will be created between the clamping plate and the frame. At this time, the self-locking insert falls down and is located in the gap between the clamping plate and the frame, thereby preventing the clamping plate from resetting and achieving the purpose of restricting the movement of the clamping plate.

[0015] The frame of this utility model is also hinged with a support device, which includes: A storage slot is recessed at the bottom of the frame; The support feet are rotatably connected to the wall of the storage slot via a shaft; A drive structure is mounted on the frame and is used to control the rotation of the support leg and maintain it in a first or second position; wherein, in the first position, the support leg is retracted into the storage slot; and in the second position, the support leg leaves the storage slot and remains perpendicular to the frame.

[0016] By adopting the above technical solution: This utility model uses retractable support legs. When supporting, the support legs leave the storage slot and are used to support the frame. When storing, the support legs can be stored in the storage slot, thereby preventing the support legs from colliding with obstacles when moving.

Detailed Implementation

[0025] 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.

[0026] Example 1: like Figures 1-6 As shown, this embodiment provides a portable fire extinguisher, including a mobile frame 10 and a fire extinguisher 11 placed on the mobile frame 10. In this embodiment, no improvement is made to the fire extinguisher. Therefore, the fire extinguisher in this embodiment can be any existing type of fire extinguisher.

[0027] The movable frame 10 in this embodiment includes: The frame 100 is rotatably connected to the wheels 101 and has a support base 102 for placing the fire extinguisher 11. The limiting ring 103 is fixed on the frame 100. In this embodiment, the limiting ring 103 is semi-circular and its two ends are fixedly connected (by welding) to the frame 100. A clamping device is provided on the frame 100; The clamping device includes a clamping plate 20 that can move relative to the frame 100, a pressure block 21 that is telescopically mounted on the support base 102, and a lever structure that is connected between the pressure block 21 and the clamping plate 20. When the fire extinguisher 11 is placed on the support base 102, the lever structure is controlled by the pressure block 21 to drive the clamping plate 20 to move closer to the limit ring 103.

[0028] In this embodiment, the support base 102 is provided with a bottom groove 102a, and the frame 100 is provided with an installation cavity 100a. The bottom groove 102a is connected to the installation cavity 100a. In this embodiment, the pressure block 21 is slidably connected to the bottom groove 102a. The pressure block 21 is partially exposed in the bottom groove 102a, and a support spring 21a is provided between the pressure block 21 and the bottom of the bottom groove 102a.

[0029] The lever structure in this embodiment includes: The lever plate 30 is rotatably connected to the frame 100 via the hinge shaft 31, and the hinge seat 32 is fixedly connected in the mounting cavity 100a in this embodiment; The drive plate 33 is slidably connected to the frame 100 and can be controlled to rise by one end of the lever plate 30. In this embodiment, a first slide rail 33a is installed on the inner wall of the frame 100, and the drive plate 33 is slidably connected to the first slide rail 33a. Among them, an active area 33b for the drive plate 33 to move is formed between the clamping plate 20 and the frame 100, and a mutually adapted protrusion 40 and groove 41 are provided on the mating surface of the clamping plate 20 and the drive plate 33. When the drive plate 33 slides, the protrusion 40 can enter or leave the groove 41; when the protrusion 40 leaves the groove 41, the protrusion 40 pushes up the clamping plate 20 and drives the clamping plate 20 to move closer to the limit ring 103.

[0030] The clamping plate 20 in this embodiment includes: The clamping plate 200 has a limiting slide post 201 on the side near the frame 100; The first limiting spring 202 is fixedly connected to the limiting slide 201; The frame 100 is provided with a limiting groove 203 for the insertion of the limiting slide 201, and the other end of the first limiting spring 202 is fixedly connected to the limiting groove 203.

[0031] The lever plate 30 in this embodiment includes: The plate 300 is rotatably connected to the hinge seat 32 of the frame 100 via the hinge shaft 31; The first rod portion 301 is integrally formed on one side of the plate 300; The second rod portion 302 is integrally formed on the other side of the plate 300; The first rod 301 has a through groove 301a, and the bottom of the pressure block 21 is equipped with a limiting pin 301b that can slide in the groove 301a. In this embodiment, the bottom of the pressure block 21 is integrally formed with a lifting column 301c, and the two sides of the lifting column 301c are fixedly connected with the limiting pins 301b.

[0032] In this embodiment, the bottom of the drive plate 33 is integrally formed with a lifting plate 50. The lifting plate 50 is provided with a slot 51 for the second rod part 302 to be inserted. The inner wall of the mounting cavity 100a in this embodiment is fixedly connected with a second slide rail 52, and the lifting plate 50 is slidably connected to the second slide rail 52.

[0033] In this embodiment, the frame 100 is also slidably connected with a self-locking plug 60. The self-locking plug 60 can fall down after the pressing plate 200 moves close to the limiting ring 103 and is used to restrict the movement of the pressing plate 200.

[0034] In this embodiment, a pressure shaft 40a is rotatably connected to the protrusion 40. During the lifting and lowering movement of the drive plate 33, the pressure shaft 40a contacts and rotates with the groove wall of the groove 41, thereby guiding the protrusion 40 into or out of the groove 41.

[0035] In this embodiment, a handrail 100f is fixedly connected to the frame 100.

[0036] refer to Figures 1-6 The principle of this embodiment is: When the fire extinguisher is not in use, the distance between the clamping plate (clamping plate body) and the limiting ring is slightly larger than the cross-sectional diameter of the fire extinguisher, so that the fire extinguisher can be easily placed on the support base. When the fire extinguisher is placed on the support base, the bottom of the fire extinguisher contacts the pressure block. The pressure block is pressed down and the support spring is squeezed. The limiting pins on both sides of the lifting column at the bottom of the pressure block apply pressure to the first rod and control the second rod of the lever to lift up. The second rod supports the lifting plate to rise and causes the drive plate to rise. After the drive plate rises, the protrusion leaves the groove and drives the clamping plate to move towards the limiting ring. The fire extinguisher can be clamped by the clamping plate and the limiting spring, which can prevent the fire extinguisher from shaking when moving.

[0037] When the pressure plate moves toward the limit ring, the space between the pressure plate and the frame expands. At this time, the self-locking insert descends and is located between the pressure plate and the frame, thereby preventing the pressure plate from resetting.

[0038] When you need to remove the fire extinguisher, first pull the self-locking plug upwards, then lift the fire extinguisher. After the fire extinguisher is lifted, the pressure block loses pressure and is reset by the support spring. The limit pin at the bottom of the pressure block controls the first rod to rise, and then controls the second rod of the lever plate to fall. After the second rod falls, the lifting plate loses the support of the second rod (and the falling of the second rod can also drive the lifting plate to fall), and the drive plate falls. After the drive plate falls, the clamping block loses its restraint and is pulled back by the first limit spring and moves away from the limit stop ring, so that the fire extinguisher can be removed smoothly.

[0039] Example 2: like Figures 7-11 As shown, this embodiment, based on embodiment 1, adds a support device to the frame. The support device in this embodiment is hinged to the frame and includes: The storage slot 70 is recessed at the bottom of the frame 100; The support foot 71 is rotatably connected to the wall of the storage groove 70 via a drive shaft; The drive structure is mounted on the frame 100 and is used to control the rotation of the support leg 71 and maintain it in a first position or a second position. In the first position, the support leg 71 is stored in the storage slot 70. In the second position, the support leg 71 leaves the storage slot 70 and remains perpendicular to the frame 100.

[0040] In this embodiment, the cross-sectional shape of the support foot 70 is T-shaped, and an anti-slip layer (not shown in the figure, the material can be rubber) is fixedly connected to the support end (bottom) of the support foot 70 to improve the anti-slip effect.

[0041] In this embodiment: the driving structure includes: Drive shaft 80 is rotatably connected to frame 100; The pedal 81 is fixedly connected to the drive shaft 80; A limiting structure is provided on the drive shaft 80, and a slot for the limiting structure to be engaged is provided on the frame 100. The transmission structure is connected between the drive shaft and the support leg; The card slot is composed of a first card slot 821 and a second card slot 822, which correspond to the first pose and the second pose, respectively.

[0042] The limiting structure in this embodiment includes: The mounting groove 90 is recessed on the drive shaft 80; The card holder 91 is slidably connected to the mounting groove 90, and partially exposed in the mounting groove 90; The second limiting spring 92 has its two ends connected to the bottom of the slot of the card seat 91 and the mounting slot 90, respectively; The card holder 91 has a recessed groove 93 on the side away from the second limiting spring 92, and a roller 94 is rotatably connected in the groove 93.

[0043] The transmission structure in this embodiment includes: The first transmission wheel 95 is coaxially connected to the drive shaft 80 via the first transmission shaft 95a; The second drive wheel 96 is connected to the support leg 71 via the second drive shaft 96a; The transmission belt 97 is connected between the first transmission wheel 95 and the second transmission wheel 96.

[0044] In this embodiment, the bottom of the frame 100 is recessed and provided with two transmission grooves 98, in which the first transmission wheel, the second transmission wheel and the transmission belt are all installed.

[0045] In this embodiment, the top of the transmission groove 98 is recessed and provided with a lifting groove 990. The tension wheel mounting seat 991 is slidably connected in the lifting groove 990. The tension wheel mounting seat 991 is rotatably connected to the tension wheel 992, which is in contact with the transmission belt. The frame 100 is threadedly connected with a clamping bolt 993. One end of the clamping bolt 993 can abut against the tension wheel mounting seat 991. During long-term use, if the transmission belt and the transmission wheel slip, the clamping bolt can be turned to drive the tension wheel down and ensure the tensioning effect of the transmission belt.

[0046] In this embodiment, a limiting part 70a is provided on the wall of the storage groove 70, and the limiting part contacts the supporting foot when the supporting foot 71 is in the second position.

[0047] refer to Figures 7-11 The principle of this embodiment is: When the mobile frame is idle, the drive shaft is rotated clockwise by stepping on the pedal, causing the holder (including rollers) on the drive shaft to enter the second slot. The rotation of the drive shaft drives the support leg to leave the storage slot and maintain the second position (e.g., Figures 7-8 In the second position, the mobile frame is supported by the support feet when constrained.

[0048] When the mobile frame needs to be moved, the drive shaft is rotated counterclockwise by stepping on the pedal, and the card on the drive shaft enters the first slot. The rotation of the drive shaft drives the support foot to be stored in the storage slot through the transmission structure (the first position). When passing through the road obstacle, the support foot can avoid colliding with the road obstacle.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
