[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] like Figures 1 to 5 Shown

[0026] A mounting device for a fire extinguisher bracket of a passenger boarding ladder comprises a mounting frame 1, a placement bucket 2 and a fire extinguisher body 8. A symmetrically arranged semicircular bucket cover 6 is installed on the top of the placement bucket 2 through a hinge. An inclined reset spring 7 is installed on the inner wall of the opposite side of the placement bucket 2. The two reset springs 7 are symmetrical to each other. The top ends of the two reset springs 7 are respectively installed on the outer walls 7 at the bottoms of the two bucket covers 6. When the fire extinguisher body 8 needs to be taken out, the hand can be directly inserted into the placement bucket 2 to lift the fire extinguisher body 8 upward. After the fire extinguisher body 8 is taken to the outside of the placement bucket 2, the two bucket covers 6 can be reset to a horizontal state under the action of the two reset springs 7. A symmetrically installed limit seat 10 is slidingly arranged on the inner side of the placement bucket 2. The two limit seats 10 are provided with arc-shaped limit grooves 14 on the opposite sides. The two sides of the fire extinguisher body 8 are respectively in contact with the two arc-shaped limit grooves 14, so that the fire extinguisher body 8 can be placed firmly.

[0027] In a specific embodiment, a symmetrically arranged movable groove 11 is opened on the inner wall of the bottom of the placement barrel 2, and the inner walls of the two movable grooves 11 are slidably connected with movable plates 12. The top ends of the two movable plates 12 are respectively fixedly installed on the outer walls of the bottoms of the two limit seats 10. Symmetrically arranged compression springs 13 are installed on the inner walls on the opposite sides of the placement barrel 2, and the opposite ends of the two compression springs 13 are respectively installed on the outer walls of one side of the two movable plates 12. A placement groove 9 is opened on the inner wall of the bottom of the placement barrel 2, and the bottom end of the fire extinguisher body 8 is in contact with the inner wall of the bottom of the placement groove 9.

[0028] Furthermore, the mounting frame 1 is composed of a mounting plate 3, a bottom support plate 4 and a stabilizing support plate 5. The bottom support plate 4 is fixedly mounted on the bottom outer wall of the placement bucket 2, and the stabilizing support plate 5 is fixedly mounted in the middle position of the placement bucket 2. The placement bucket 2 can be stably mounted at an appropriate position at the bottom of the boarding ladder in conjunction with expansion bolts.

[0029] The implementation principle of the installation device of the fire extinguisher bracket of the passenger boarding ladder of this embodiment is as follows:

[0030] By setting up the mounting frame 1, and the mounting frame 1 is composed of a mounting plate 3, a bottom support plate 4 and a stable support plate 5, the placement barrel 2 can be stably installed at an appropriate position at the bottom of the boarding ladder in conjunction with expansion bolts. By installing reset springs 7 at the bottom positions of the two barrel covers 6, when the fire extinguisher body 8 needs to be taken, the hand can be directly inserted into the placement barrel 2 to lift the fire extinguisher body 8 upward. After the fire extinguisher body 8 is taken to the outside of the placement barrel 2, the two barrel covers 6 can be reset to a horizontal state under the action of the two reset springs 7. When the fire extinguisher body 8 is placed, the bottom end of the fire extinguisher body 8 is directly placed on the two barrel covers 6, so that the fire extinguisher body 8 is on the two barrel covers. The barrel covers 6 are squeezed so that the fire extinguisher body 8 can enter the placement barrel 2. When the two sides of the bottom end of the fire extinguisher body 8 are respectively in contact with the opposite sides of the top of the two limit seats 10, the two limit seats 10 are squeezed to both sides by the two movable grooves 11, two movable plates 12 and two compression springs 13, so that the two sides of the fire extinguisher body 8 are respectively in contact with the arc-shaped limit grooves 14, and the bottom end of the fire extinguisher body 8 is in contact with the bottom inner wall of the placement groove 9, so as to achieve a stable placement of the fire extinguisher body 8. After the fire extinguisher body 8 is completely entered into the placement barrel 2, under the action of the two reset springs 7, the two barrel covers 6 can be reset to a horizontal state.
