DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1 The figure shows a large-capacity and easy-to-move fire extinguisher, which includes a base frame 1 and a fire extinguisher body 18. A column 2 is fixedly installed on the upper end of the base frame 1, a handle 3 is fixedly installed on the upper end of the column 2, a rotating shaft 4 is rotatably installed inside the base frame 1, and rollers 5 are fixedly installed at both ends of the rotating shaft 4. A fixing plate 6 is fixedly installed on the inner side of the column 2, and a double-axis cylinder 7, a control switch 8 and a power supply 9 are fixedly installed on the outer side of the fixing plate 6. A sliding sleeve 10 is movably installed on the outer side of the column 2, and a connecting frame 11 is fixedly installed inside the sliding sleeve 10. A movable plate 12 is fixedly installed at the lower end of the connecting frame 11, a shock absorber 13 is fixedly installed on the upper end of the movable plate 12, and a support plate 14 is fixedly installed on the upper end of the shock absorber 13. A positioning hole 15 is opened inside the support plate 14, a positioning frame 16 is movably installed on the upper end of the fixing plate 6, and a buffer pad 17 is fixedly installed on the lower end of the positioning frame 16. A positioning block 19 is fixedly installed on the lower end of the fire extinguisher body 18.

[0025] See also Figure 1 A roller 5 is respectively arranged on both sides of the base frame 1, and the side of the base frame 1 away from the roller 5 is inclined.

[0026] In this embodiment, the roller 5 drives the base frame 1 to move. In the absence of external force, the inclined end of the base frame 1 contacts the ground, thus supporting the base frame 1.

[0027] See also Figure 1 The column 2 is perpendicular to the base frame 1 , two columns 2 are symmetrically arranged, and the handle 3 is inclined to the column 2 .

[0028] In this embodiment: the operator grasps the handle 3 and pushes the roller 5 forward.

[0029] Working principle: The operator turns on the double-axis cylinder 7 through the control switch 8, and the output ends on the upper and lower sides of the double-axis cylinder 7 move at the same time. The output end on the lower side drives the connecting frame 11 to move downward, and the sliding sleeve 10 connected to the connecting frame 11 moves along the column 2 to guide the connecting frame 11. The output end on the upper side of the double-axis cylinder 7 drives the positioning frame 16 to move upward, and then the fire extinguisher body 18 is moved to the upper end of the support plate 14, and the positioning block 19 is sleeved in the positioning hole 15 to position the bottom of the fire extinguisher body 18. Then the double-axis cylinder 7 is turned on again, and the output end on the lower side drives the connecting frame 11 to move downward. The sliding sleeve 10 connected to the connecting frame 11 moves along the column 2 to guide the connecting frame 11. The output end on the upper side of the double-axis cylinder 7 drives the positioning frame 16 to move upward, and then the fire extinguisher body 18 is moved to the upper end of the support plate 14, and the positioning block 19 is sleeved in the positioning hole 15 to position the bottom of the fire extinguisher body 18. The connecting frame 11 is driven to move upward, and the output end on the upper side drives the positioning frame 16 to move downward. When the positioning frame 16 is sleeved on the upper end of the fire extinguisher body 18, the double-axis cylinder 7 is closed, and the positioning frame 16 positions the top of the fire extinguisher body 18. The operator grabs the handle 3 and pushes the roller 5 forward. The roller 5 drives the base frame 1 to move. In the absence of external force, the inclined end of the base frame 1 contacts the ground, which supports the base frame 1 and prevents it from tipping over. During the movement, the shock absorber 13 buffers and reduces shocks on the fire extinguisher body 18 through the support plate 14, thereby improving the stability during movement.

[0030] Example 2

[0031] See also Figure 2 The double-axis cylinder 7 is electrically connected to the control switch 8, and the output end on the lower side of the double-axis cylinder 7 is fixedly connected to the connecting frame 11.

[0032] In this embodiment: the operator turns on the double-axis cylinder 7 by controlling the switch 8, and the output ends on the upper and lower sides of the double-axis cylinder 7 move simultaneously, and the output end on the lower side drives the connecting frame 11 to move up and down, and the sliding sleeve 10 connected to the connecting frame 11 moves along the column 2 to guide the connecting frame 11.

[0033] See also Figure 4 The movable plate 12 is located directly above the base frame 1 , and four shock absorbers 13 are provided.

[0034] In this embodiment, the shock absorber 13 plays a role in buffering and absorbing shock for the support plate 14 .

[0035] See also Figure 1 and Figure 5 The center of the positioning block 19 and the center of the fire extinguisher body 18 are located on the same vertical line, and the positioning block 19 fits the inner side of the positioning hole 15 .

[0036] In this embodiment, the positioning block 19 is sleeved in the positioning hole 15 to position the bottom of the fire extinguisher body 18 .

[0037] See also Figure 4 The output end on the upper side of the double-axis cylinder 7 is fixedly connected to the positioning frame 16, and the positioning frame 16 is sleeved and installed on the outer side of the upper end of the fire extinguisher body 18.

[0038] In this embodiment, the output end of the upper side of the double-axis cylinder 7 drives the positioning frame 16 to move up and down, and after being sleeved on the upper end of the fire extinguisher body 18, it plays a positioning role on the top of the fire extinguisher body 18.
