[0022] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] Reference to “an embodiment” in this text means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor does it necessarily refer to a particular alternative embodiment in isolation or in preference to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The structure of the present application is a handheld fire extinguishing stick structure, and the specific structure is as shown in Figures 1-6 .

[0026] As shown in Figure 1 , the fire extinguishing stick structure includes a holding cylinder 10. The outer wall of the holding cylinder 10 is provided with a push block 20 that translates along the outer wall of the holding cylinder 10 and a removable safety cover 30. The outer wall of the holding cylinder 10 is also provided with a plurality of strip-shaped anti-skid grooves 10. In combination with Figure 1 and Figure 2 , a switch mechanism 40 for controlling the opening of the fire extinguishing stick is arranged in the holding cylinder 10, and the push block 20 is connected with the switch mechanism 40 and is used to control the on-off of the switch mechanism 40.

[0027] The push block 20 has an initial position and an end position. Specifically, as shown in Figure 1 and Figure 2 , when the push block 20 is in the initial position, the switch mechanism 40 is in the off state, and at this time, the safety cover 30 is arranged above and outside the push block 20 and is used to limit the push block 20 to the initial position. The safety cover 30 above the push block 20 in the Figure 1 and Figure 2 state is removed, and then the push block 20 is pushed upward, obtaining Figure 3 andFigure 4 As shown, at this time, the dial 20 is in the terminal position, the switch mechanism 40 is in the connected state, and the fire extinguishing rod is in the open state.

[0028] The fire extinguishing rod structure of the embodiment sets the dial 20 that translates on the outer wall of the holding cylinder 10 to control the switch mechanism 40, and the safety block 30 blocks the movement of the dial 20 in the initial position. After the safety block 30 is removed, the dial 20 can be pushed to open the fire extinguishing rod. The dial 20 does not need to be set at the position close to the bottom of the holding cylinder 10, and the safety block 30 is also set on the outer wall of the holding cylinder 10. Therefore, the convenience of use is improved.

[0029] It is more in line with the general use habit to push the dial 20 upward to open the fire extinguishing rod. However, in other embodiments, the safety block 30 can also be set on the lower outer side of the dial 20. After the safety block 30 is removed, the dial 20 can be pushed horizontally downward to connect the switch mechanism 40 and open the fire extinguishing rod. Alternatively, the safety block 30 can also be set on the left side or the right side of the dial 20. After the safety block 30 is removed, the dial 20 can be pushed horizontally leftward or rightward to connect the switch mechanism 40 and open the fire extinguishing rod.

[0030] In some embodiments, as shown in Figure 4 and Figure 5 , the switch mechanism 40 includes a metal spring 41 and a main control circuit board 42. The spring 41 can be made of copper material, which is beneficial to reduce the resistance. The spring 41 is fixedly connected to the dial 20, and the main control circuit board 42 is provided with a positive plate 421 and a negative plate 422, and the positive plate 421 and the negative plate 422 are arranged along the translation direction of the dial 20. The spring 41 is provided with two U-shaped bends 411, and the U-shaped bends 411 of the spring 41 are in close contact with the surface of the main control circuit board 42. When the dial 20 is in the terminal position, the two U-shaped bends 411 simultaneously contact the positive plate 421 and the negative plate 422 to make the switch mechanism 40 connected. When the dial 20 is in the initial position, as shown in Figure 2 , the lower U-shaped bend 411 of the spring 41 contacts the lower negative plate 422, and the upper U-shaped bend 411 is separated from the positive plate 421, so as to realize the disconnection of the switch mechanism 40, and the fire extinguishing rod is in the closed state. Due to the blockage of the safety block 30, the dial 20 cannot move to the terminal position (the conduction position), which avoids the dial 20 being misoperated to translate to connect the switch mechanism 40 and cause the fire extinguishing rod to be misopened.

[0031] In some embodiments, as shown in Figure 4 , the holding cylinder 10 is also provided with a power supply 50, and the power supply 50 is electrically connected to the main control circuit board 42. The power supply 50 supplies power to the entire fire extinguishing rod.

[0032] In some embodiments, in combination with Figure 5 and Figure 6As shown, the shift block 20 is provided with two upper and lower parallel positioning posts 21. Two positioning holes 412 are respectively provided between the two U-shaped bends 411 of the spring clip 41. The positioning posts 21 are inserted into the positioning holes 412 to prevent relative rotation between the spring clip 41 and the shift block 20. Furthermore, an internally threaded hole 23 is provided between the two positioning posts 21. A screw 43 passes through the through hole 413 between the two positioning holes 412 and is then screwed into the internally threaded hole 23 to fully secure the spring clip 41 to the shift block 20.

[0033] In other embodiments, the switch mechanism may also adopt common switch elements, for example, the switch mechanism adopts a two-speed sliding switch, and the shifting rod and the shifting block of the sliding switch are fixedly connected.

[0034] In some embodiments, as Figure 5 As shown, the wall of the gripping tube 10 is provided with a notch 12, the shifting block 20 is engaged with the notch 12 and forms a sliding connection with the notch 12, and the vertical length direction of the notch 12 is the translation direction of the shifting block 20. Figure 5 and Figure 6 As shown, the shift block 20 is provided with two latches 22 inserted into the slot 12 , the latches 22 are respectively engaged with the slot 12 and the latches 22 are slidably connected with the side walls of the slot 12 , so that the shift block 20 can translate in a straight line and the shift block 20 will not fall out of the slot 12 .

[0035] In some embodiments, as Figure 5 As shown, the outer wall of the grip tube 10 is provided with a vertical groove 13, the notch 12 is provided in the vertical groove 13, and the shift block 20 is placed in the vertical groove 13, which is conducive to reducing the height of the shift block 20 protruding from the grip tube 10. In addition, the outer surface of the shift block 20 is provided with an anti-slip protrusion 201. In addition, as shown in FIG. Figure 5 As shown, a transverse groove 14 is further provided on the outer wall of the grip tube 10, which is connected to the vertical groove 13. A safety block 30 is detachably fixed in the transverse groove 14. When the fire extinguisher needs to be opened, after removing the safety block 30, the upper end of the dial block 20 is pushed into the transverse groove 14 to open the switch mechanism 40.

[0036] Specifically, in some embodiments, the safety block piece 30 is made of a soft rubber that is easily deformed to facilitate removal of the safety block piece 30 from the transverse groove 14. Figure 5 and Figure 6As shown, the safety stopper 30 is provided with a long clamping tongue 32 and a short clamping tongue 31 at two ends of one side of the safety stopper 30, respectively, and the long clamping tongue 32 and the short clamping tongue 31 are inserted into the corresponding clamping holes 141 of the horizontal slot 14 to form clamping fixation. One end of the safety stopper 30 is provided with a pull tab 33 for pulling the safety stopper 30 out of the horizontal slot 14. When it is necessary to open the fire extinguishing rod, the safety stopper 30 is pulled out through the pull tab 33 so that the safety stopper 30 no longer blocks the push block 20, and the short clamping tongue 31 can be pulled out of the clamping hole 141 or the short clamping tongue 31 and the long clamping tongue 32 can be pulled out of the two clamping holes 141.
