[0028] A first arm 2, which is arranged to be higher on the left and lower on the right and whose other end is movably mounted on the right side of the upper end of the slide rail base 1, is movably arranged on the right end of the movable part of the first cylinder 4, and a second arm 3, which is arranged to be lower on the left and higher on the right and whose other end is movably mounted on the left side of the upper end of the sliding seat 9, is movably arranged on the left end of the movable part of the first cylinder 4. The first arm 2 and the second arm 3 are used in conjunction with each other to enable the sliding seat 9 to circulate left and right along the slide rail base 1;

[0029] The vertical frame 7 arranged vertically is arranged on the left side of the slide rail base 1, and a mounting carrier is provided for components such as a slide plate 72 through the vertical frame 7, and two slide plates 72 arranged vertically and extending from the lower side of the vertical frame 7 are symmetrically slidably connected to the left end of the vertical frame 7, and the slide plates 72 are used to realize the lifting movement, and then the auxiliary frame 71 located on the upper side of the slide plates 72 is movably installed inside the vertical frame 7, and a mounting carrier is provided for the push-pull rod 75 through the auxiliary frame 71;

[0030] The two push-pull rods 75, whose other ends are movably mounted on the upper end of the slide 72, are symmetrically and movably arranged on the left side of the lower end of the auxiliary frame 71. The auxiliary frame 71 is connected to the slide 72 through the push-pull rods 75. The movable part of the second cylinder 6, whose two fixed parts are movably arranged on the left end of the vertical part of the inverted U-shaped frame 5, is symmetrically and movably mounted on the right end of the auxiliary frame 71. The auxiliary frame 71 is driven to move through the second cylinder 6.

[0031] Two first connecting rods 73 located at the lower side of the second cylinder 6 and the other ends of which are movably arranged with the sliding seat 9 are symmetrically and movably installed on the right end of the vertical frame 7. The vertical frame 7 is connected to the sliding seat 9 through the first connecting rods 73, and two second connecting rods 74 located at the upper side of the second cylinder 6 and the other ends of which are movably arranged with the left end of the vertical part of the inverted U-shaped frame 5 are movably installed on the right end of the vertical frame 7.

[0032] When in use, the triangular structure formed by the first arm 2, the second arm 3 and the slide rail base 1 has an appearance close to a straight line. At this time, the thrust arm of the triangular structure is the largest. Then, the second cylinder 6 is started to drive the auxiliary frame 71 to move, thereby pulling the two push-pull rods 75 to move upward, so that the two slide plates 72 move upward along the vertical frame 7, and the first cylinder 4 is started to move the upper part of the first arm 2 and the upper part of the second arm 3 upward, so that the sliding seat 9 moves rightward along the slide rail base 1 to achieve the lifting movement.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the left end surface of the slide plate 72 is recessed to the right to form an L-shaped groove 721, and the L-shaped groove 721 provides an installation space for the cross bar 83. The two cross bars 83 that penetrate the vertical parts of the L-shaped groove 721 and fit on the bottom end of the vertical parts of the L-shaped groove 721 are symmetrically arranged on the right end of the mobile trolley 8. The cross bar 83 and the L-shaped groove 721 are used in conjunction with each other to facilitate the disassembly and assembly between the mobile trolley 8 and the slide plate 72.

The two push handle rods 82 are used in conjunction with each other to push the mobile trolley 8.

[0035] Two baffles 81 attached to the outer ends of the slide plate 72 are symmetrically arranged on the right end of the cross bar 83. The two baffles 81 are used in combination to limit the installation of the moving cart 8, and the two right end faces between the two baffles 81 overlap with the right end face of the cross bar 83 and the first magnetic plate 84 attached to the inner right wall of the L-shaped groove 721 is symmetrically embedded on the right end of the cross bar 83, and then the second magnetic plate 722 located on the upper side of the cross bar 83 and the left end face overlaps with the inner right wall of the L-shaped groove 721 is embedded in the right wall of the horizontal part of the L-shaped groove 721. The first magnetic plate 84 and the second magnetic plate 722 are used in combination to push the moving cart 8 in a small range.

[0036] The fire fighting equipment is installed in the mobile trolley 8. When in use, the first cylinder 4 and the second cylinder 6 are activated, so that the mobile trolley 8 is lowered from the compartment to the ground, and the mobile trolley 8 and the slide plate 72 are moved relative to each other, so that the cross bar 83 moves upward along the L-shaped groove 721, so that the cross bar 83 moves into the lateral part of the L-shaped groove 721, and the restriction on the mobile trolley 8 is released;

[0037] At this time, the first magnetic plate 84 and the second magnetic plate 722 on the cross bar 83 fit together, and a repulsive force is generated between the first magnetic plate 84 and the second magnetic plate 722. Under the action of the repulsive force, the cross bar 83 moves outward, and then the mobile cart 8 moves outward for a distance, thereby creating a space between the push handle 82 and the vertical frame 7. The operator can directly enter the space, hold and push the push handle 82, and conveniently push the mobile cart 8 to move the fire-fighting equipment to the required position, effectively avoiding the additional operation of pulling the mobile cart 8, and facilitating use.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
