The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A type of fire truck for laying water hoses, such as Figures 1-9 As shown, the fire truck includes a main body 1 and a take-up roller 14. A housing 2 is installed on the outer surface of the main body 1. A pressing assembly 8 is provided on the take-up roller 14. A groove 4 is provided in the lower part of the housing 2. A first motor 5 is installed on one side of the housing 2, and the output end of the first motor 5 is connected to a bidirectional lead screw 7 extending into the groove 4. When the take-up roller 14 needs to be moved upward, the first motor 5 can be started. The operation of the first motor 5 can drive the bidirectional lead screw 7 to rotate. Two threaded seats 6 are sleeved on the outer wall of the bidirectional lead screw 7. One end of the bidirectional lead screw 7 is connected to the inner wall of the groove 4 through a bearing. When the bidirectional lead screw 7 rotates, it will drive the two threaded seats 6 to move. The bearing can improve the stability of the bidirectional lead screw 7 when rotating. Movable grooves 11 are provided on both sides of the housing 2. Movable plates 13 are provided inside the two movable grooves 11 so that the movable plates 13 can slide inside the movable grooves 11 and allow the take-up roller 14 to move.

[0042] SeeFigures 2-5 One side of the movable plate 13 is provided with the second motor 12, and the output end of the second motor 12 is connected with the second rotating seat 16. One side of the other movable plate 13 is connected with the first rotating seat 15 through a bearing. The first rotating seat 15 and the second rotating seat 16 are convenient for the rotating of the winding roller 14, so that the winding roller 14 can wind the water belt. The first rotating seat 15 and the second rotating seat 16 are both provided with cavities 22. The cavities 22 are internally provided with return springs 19. One end of the two return springs 19 is respectively connected with an insertion block 17 penetrating to the outside of the first rotating seat 15 and the second rotating seat 16. When the insertion block 17 moves into the cavity 22, the insertion block 17 will press the return spring 19, so that the return spring 19 is forced to compress, which is convenient for the subsequent reset movement of the insertion block 17. The box body 2 is also provided with a cover plate 3 rotatably arranged thereon, which is convenient for covering the box body 2.

[0043] Referring to Figures 2-7 The two sides of the winding roller 14 are both provided with insertion slots 18. The insertion block 17 is located in the insertion slot 18. The insertion block 17 is slidably connected with the cavity 22. The insertion block 17 is adapted with the insertion slot 18. When the winding roller 14 is installed, the insertion block 17 can be inserted into the insertion slot 18, so that the winding roller 14 can be locked and positioned, preventing the winding roller 14 from falling. The two movable plates 13 are provided with a lifting plate 10. The bottom of the lifting plate 10 and the threaded seat 6 are connected with a push plate 9 through a rotating shaft. When the threaded seat 6 moves, it will drive the push plate 9 to rotate. The push plate 9 can push the lifting plate 10 to move, so as to adjust the height of the lifting plate 10. The movable plate 13 is slidably connected with the movable slot 11. The outer wall of the threaded seat 6 is attached to the inner wall of the groove 4, so that the movable plate 13 can slide in the movable slot 11 and drive the winding roller 14 to move, so that the winding roller 14 can move upwards.

[0044] Specifically, the pressing assembly 8 includes a sliding groove 802 and two limiting grooves 805 arranged on both sides of the winding roller 14. The sliding groove 802 is internally provided with a sliding block 803, and two locking grooves 804 are arranged on the sliding block 803. The limiting groove 805 is internally provided with a spring 806, and one end of the spring 806 is connected with a movable block 808. The movable block 808 is provided with a locking block 807 extending into the sliding groove 802. The two sliding blocks 803 are provided with a pressing frame 801. The pressing frame 801 is slidably connected with the sliding groove 802 through the sliding block 803. The bottom of the sliding block 803 and the top of the locking block 807 are both provided with inclined surfaces. The locking block 807 is adapted with the locking groove 804. The locking block 807 is slidably connected with the limiting groove 805 through the movable block 808. After the locking block 807 moves into the locking groove 804, the sliding block 803 can be locked and positioned, and the pressing frame 801 can also be positioned. After one end of the water belt is placed below the pressing frame 801, the staff can press the pressing frame 801 downward, so that the pressing frame 801 moves downward and drives the sliding block 803 to move downward.
