[0003] When not in use, fire extinguishers are usually placed in corners such as against walls. When using them for firefighting or to adjust their location, they are usually moved as a whole, which requires lifting and moving them continuously. Their weight makes the movement inconvenient, and this method of moving them is not convenient for carrying them for a long time, affecting their actual ease of use.

[0004] Therefore, we provide a portable fire extinguisher. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: A portable fire extinguisher, such as... Figures 1-4 As shown, the device includes a fire extinguisher body 1, a support cylinder 2 and a support base 3 located below the fire extinguisher body 1. The support cylinder 2 is installed on the upper end of the support base 3, and the fire extinguisher body 1 is inserted into the support cylinder 2. A connecting groove 4 is provided through the support base 3. A roller 16 and an auxiliary wheel 17 for moving the support are installed at the lower end of the support base 3. A positioning rotation arc 13 is provided on the outer side of the roller 16. The positioning rotation arc 13 is inserted into the roller 16 through a positioning tooth 15. A pull plate 7 is rotatably provided above the roller 16. A rotating sleeve 8 for adjusting the position of the positioning rotation arc 13 is provided in the middle of the lower half of the pull plate 7. A connecting rod 10 is provided between the rotating sleeve 8 and the positioning rotation arc 13. The connecting rod 10 is inserted through the connecting groove 4.

[0026] With the support of the support cylinder 2 supporting the fire extinguisher body 1, and with the rotational support of the rollers 16 and auxiliary wheels 17 below the support base 3, the device is able to move. By setting the two auxiliary wheels 17 as universal wheels, the positioning teeth 15 position the rollers 16 by rotating the positioning rotation arc 13, restricting the rotation of the rollers 16 and preventing the device from slipping during placement, thus providing stability during normal placement. Through the connection of the rotating sleeve 8 and the connecting rod 10, the pull plate 7 can simultaneously release the limiting state of the rollers 16 when it is rotated, making it easy to engage the limiting state while the device is moving, thus improving its ease of use. According to the actual needs of the device, the upper part of the pull plate 7 can be set to have a telescopic structure to meet the needs of use at different heights. Since the telescopic method is an existing structure and is not a necessary technical feature of this application, it will not be described in detail in this embodiment and the figures.

[0027] like Figures 1-4 As shown, a symmetrically distributed support plate 5 is installed on the upper end of the support base 3, and a rotating column 6 is rotatably installed in the middle of the support plate 5. The lower half of the pull plate 7 is fixedly sleeved on the outside of the rotating column 6.

[0028] The rotating sleeve 8 is fitted on the outer side of the middle part of the rotating column 6, and the rotating sleeve 8 is fixedly connected to the rotating column 6.

[0029] When the pull plate 7 is pulled to adjust the angle, under the combined support of the support plate 5 and the rotating column 6, the rotation of the pull plate 7 causes the rotating column 6 to rotate synchronously, and the rotating sleeve 8 rotates simultaneously with the rotating column 6. Thus, under the connection of the rotating sleeve 8 to the connecting rod 10, the connecting rod 10 is controlled to rotate synchronously with the pull plate 7.

[0030] like Figures 1-4 As shown, a rotating support frame 9 is installed on the outside of the rotating sleeve 8, and a connecting rod 10 is rotatably installed in the middle of the rotating support frame 9. A double-headed rotating frame 11 is rotatably connected to the end of the connecting rod 10 away from the rotating support frame 9.

[0031] A rotating auxiliary frame 12 is installed on the outer arc surface of the positioning rotating arc 13, and the rotating auxiliary frame 12 is rotatably installed in the middle of the double-headed rotating frame 11.

[0032] With the upper rotating support frame 9 rotating to connect the connecting rod 10, and with the lower double-headed rotating frame 11 and rotating auxiliary frame 12 rotating together, the connecting rod 10 can move simultaneously in terms of angle during rotation. With the length of the connecting rod 10 itself fixed, the rotating sleeve 8 can stably drive the positioning rotating arc 13 to rotate simultaneously during rotation, thereby causing the positioning rotating arc 13 and the positioning tooth 15 to disengage from the limiting state of the roller 16, ensuring that the limiting state can be accurately and automatically released during its movement, and ensuring its reliability during movement.

[0033] Example 2: A portable fire extinguisher, such as... Figures 1-4 As shown, two symmetrically distributed side fixing plates 14 are installed at the lower end of the support base 3. The roller 16 and the positioning rotation arc 13 are rotatably installed between the two side fixing plates 14.

[0034] The outer arc surface of the roller 16 has several toothed grooves, and the positioning teeth 15 are inserted into the toothed grooves.

[0035] The rotational support of the side fixing plates 14 on both sides ensures the accuracy of the roller 16 during rotation and use, and the reliable positioning of the roller 16 is ensured by the insertion and positioning of the positioning teeth 15 and the tooth groove.

[0036] like Figures 1-4 As shown, a triangular positioning plate 18 is installed on the outside of the support cylinder 2, and a triangular groove is provided through the pull plate 7 to be inserted into the triangular positioning plate 18. A positioning bracket 19 is inserted into the triangular positioning plate 18.

[0037] By inserting the triangular slot into the triangular positioning plate 18 for positioning, and then pressing the positioning frame 19 to insert and position it into the triangular positioning plate 18, the pull plate 7 is provided with position limitation to ensure the stability of the position of the pull plate 7 when it is placed and used.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
