[0020] like Figures 1 to 7As shown, a fire ladder limit frame includes a main body support base 1 made of stainless steel material, and a symmetrical fastening connection plate 2 is respectively provided on the left and right sides of the main body support base 1, and the overall fixed fit is performed through this structure. An integrally formed rectangular main body fastening and matching limit column 4 is provided at the center position of the upper end of the main body support base 1, which is the main body matching structure during the limit fit. A rectangular main body fastening connection hole 3 is provided at the upper end of the fastening connection plate 2, and the limit frame as a whole can be locked and matched with the fire equipment structure through the fastening bolts at this position. The side of the main body fastening and matching limit column 4 is provided with limit matching combination holes 5 evenly distributed up and down, which can be accurately positioned and matched with the matching structure during the movable adjustment of the movable parts, and can provide auxiliary support for the movable structure components, ensuring better structural bearing strength at the matching position. The upper end of the main body fastening and matching limit column 4 is provided with an arc-shaped support and stable matching groove 6 with an opening upward, which can be matched with the matching structure at the upper end for positioning during installation, and can also improve the overall stability of the limit frame during installation, and can also be more comprehensively associated with the main body of the fire-fighting equipment. The lower end of the main body support base 1 is located at the center of the left and right directions and is provided with an inverted T-shaped integral stable combination seat 7, which can be combined with the slide rail structure to make the overall load-bearing stability better during matching, and can be safely and smoothly adjusted according to needs. The width of the integral stable combination seat 7 is greater than half of the left and right width of the main body support base 1. It adopts a brand-new structural design, and can be adjusted in position by the way of slide rail matching during installation. By setting the limit matching hole on its main structure, it can ensure that the movable parts can provide accurate matching when they are matched in different positions, and can also play a supporting and auxiliary role for the movable parts, so that the movable structure components are safer and more durable when in use, and the safety of the fire-fighting equipment is more reliable when in use.

[0021] Preferably, the length of the fastening connecting plate 2 is smaller than that of the main support base 1, so that the structure of the fastening position occupies less space, the fastening and matching operation is more convenient during use, and more space can be provided for the matching of other surrounding components.

[0022] Preferably, the thickness of the fastening connecting plate 2 is the same as the thickness of the main supporting base 1, so that the overall structure has better flatness, is more convenient during production and processing, and has relatively low production costs.

[0023] Preferably, the left and right sides of the upper end of the bottom structure of the integral stable assembly seat 7 are respectively provided with a safe and stable fitting inclined plane. When matched with the guide rail structure, the inclined plane structure can make the fitting area larger and the stability during matching stronger.

[0024] Preferably, the length of the integral stable assembly seat 7 is the same as that of the main support base 1, so that the structural bearing strength at the lower end can reach the maximum, and the safety is higher when used in combination in the later stage.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
