[0028] like Figures 1 to 5 As shown, the utility model provides a floor blower that is convenient for pulley storage, comprising:

[0029] A floor blower body 1, with protective nets 2 fixedly installed at both ends of the floor blower body 1, and a telescopic pull rod 3 fixedly installed on the top of the floor blower body 1;

[0030] A storage mechanism, which is arranged at the rear side of the floor blower body 1;

[0031] A fixing mechanism, which is arranged inside the floor blower body 1;

[0032] Wherein, the storage mechanism includes a pulley 12;

[0033] Vertical grooves 4 are provided at both ends of the rear side of the floor blower body 1, a vertical rod 5 is fixedly installed inside the vertical groove 4, a movable block 6 is movably sleeved on the outer side of the vertical rod 5, a cross plate 8 is fixedly installed between the inner sides of the movable block 6, mounting blocks 10 are fixedly installed below both ends of the cross plate 8, a connecting shaft 11 is fixedly installed between the inner sides of the mounting blocks 10, and a pulley 12 is movably sleeved on the outer side of the connecting shaft 11.

[0034] When the floor blower is needed, it is only necessary to pull the horizontal plate 8 downward so that the horizontal plate 8 drives the movable block 6 to move downward. The movable block 6 moves downward around the vertical rod 5 inside the vertical groove 4 to stretch the return spring 7, so that the mounting block 10 moves downward with the movable block 6. The mounting block 10 drives the pulley 12 to move downward and contact the ground through the connecting shaft 11, and the movable block 6 is fixed by the fixing mechanism. When it needs to be stored, the return spring 7 releases the elastic potential energy to drive the movable block 6 to move upward, and the movable block 6 drives the pulley 12 to move upward to store the pulley 12.

[0035] By pulling the cross plate 8 downward, the movable block 6 drives the pulley 12 to move downward to stretch the return spring 7. After the floor blowing work is completed, the return spring 7 releases the elastic potential energy to bring the movable block 6 back to its original position, and the pulley 12 is stored. Compared with the traditional floor blower, this floor blower which is easy to store the pulley has a limiting effect on the pulley 12 through the return spring 7. When the work is completed, the return spring 7 releases the elastic potential energy to drive the pulley 12 to move upward to store the pulley 12.

[0036] Wherein, the fixing mechanism includes an inclined surface block 19;

[0037] A circular groove 14 is provided inside the floor blower body 1, and a round block 17 is movably installed inside the circular groove 14. A rectangular groove 15 is provided inside the floor blower body 1 and is located on the right side of the circular groove 14. A connecting rod 18 extending into the rectangular groove 15 is fixedly installed on the right side of the round block 17, and a bevel block 19 is fixedly connected to the outer side of the connecting rod 18.

[0038] The contact between the movable block 6 and the inclined surface of the inclined surface block 19 drives the inclined surface block 19 to move inward, and the inclined surface block 19 drives the connecting rod 18 to move inward. The connecting rod 18 drives the round block 17 to move inward to the inside of the circular groove 14, so that the inclined surface block 19 squeezes the telescopic spring 20. When the slot 9 moves to the outside of the inclined surface block 19, the telescopic spring 20 releases its elastic potential energy to push the inclined surface block 19 to the inside of the slot 9, thereby fixing the movable block 6 and pulling the push block 22. The push block 22 drives the inclined surface block 19 to move inward through the connecting block 21, thereby releasing the movable block 6.

[0039] The inclined surface of the movable block 6 contacts the inclined surface of the inclined surface block 19 to make the inclined surface block 19 move inward, and the inward movement of the inclined surface block 19 drives the telescopic spring 20 to be squeezed. When the slot 9 moves to the outside of the inclined surface block 19, the telescopic spring 20 releases its elastic potential energy to push the inclined surface block 19 to the inside of the slot 9. Compared with the traditional floor blower, this floor blower which is easy to store the pulley fixes the movable block 6 through the inclined surface block 19, and pulls the push block 22 to release the movable block 6, which is convenient for the staff to use the floor blower.

[0040] A slide groove 16 is provided at the rear side of the floor blower body 1 , a connecting block 21 is fixedly installed on the outer side of the inclined clamping block 19 , the connecting block 21 is movably connected inside the slide groove 16 , and a push block 22 is fixedly installed on the outer side of the connecting block 21 .

[0041] The push block 22 is pulled, and the push block 22 drives the inclined surface block 19 to move inward through the connecting block 21, thereby releasing the movable block 6.

[0042] A return spring 7 is elastically installed between the upper side of the vertical slot 4 and the upper side of the movable block 6 , and the return spring 7 is movably connected to the outer side of the vertical rod 5 .

[0043] The movable block 6 moves downward around the vertical rod 5 inside the vertical groove 4 to stretch the reset spring 7, so that the mounting block 10 moves downward with the movable block 6, and the mounting block 10 drives the pulley 12 to move downward and contact the ground through the connecting shaft 11. When it needs to be stored, the reset spring 7 releases its elastic potential energy to drive the movable block 6 to move upward, and the movable block 6 drives the pulley 12 to move upward to store the pulley 12.

[0044] Wherein, fixing blocks 13 are fixedly installed on the outer sides of both ends of the mounting block 10 , and the fixing blocks 13 are located on the outer sides of the connecting shaft 11 .

[0045] The connecting shaft 11 is fixed by the fixing block 13 to prevent the connecting shaft 11 from loosening and detaching from the mounting block 10 and causing the pulley 12 to fall off.

[0046] A clamping slot 9 is provided on the outer side of the movable block 6 , and the clamping slot 9 corresponds to the inclined clamping block 19 .

[0047] The movable block 6 is fixed by inserting the inclined surface clamping block 19 into the clamping slot 9, which facilitates the use of the floor blower by the staff.

[0048] A telescopic spring 20 is elastically installed between the inner side of the rectangular groove 15 and the inner side of the inclined surface block 19 , and the telescopic spring 20 is movably connected to the outer side of the connecting rod 18 .

[0049] The connecting rod 18 drives the round block 17 to move inward to the inside of the circular groove 14, so that the inclined surface block 19 squeezes the telescopic spring 20. When the groove 9 moves to the outside of the inclined surface block 19, the telescopic spring 20 releases its elastic potential energy to push the inclined surface block 19 to the inside of the groove 9, thereby fixing the movable block 6.

[0050] The working principle and use process of this utility model:

[0051] When the floor blower is needed, it is only necessary to pull the horizontal plate 8 downward so that the horizontal plate 8 drives the movable block 6 to move downward. The movable block 6 moves downward around the vertical rod 5 inside the vertical groove 4 to stretch the return spring 7, so that the mounting block 10 moves downward with the movable block 6. The mounting block 10 drives the pulley 12 to move downward and contact the ground through the connecting shaft 11, and the movable block 6 is fixed by the fixing mechanism. When it needs to be stored, the return spring 7 releases the elastic potential energy to drive the movable block 6 to move upward, and the movable block 6 drives the pulley 12 to move upward to store the pulley 12.

[0052] The contact between the movable block 6 and the inclined surface of the inclined surface block 19 drives the inclined surface block 19 to move inward, and the inclined surface block 19 drives the connecting rod 18 to move inward. The connecting rod 18 drives the round block 17 to move inward to the inside of the circular groove 14, so that the inclined surface block 19 squeezes the telescopic spring 20. When the slot 9 moves to the outside of the inclined surface block 19, the telescopic spring 20 releases its elastic potential energy to push the inclined surface block 19 to the inside of the slot 9, thereby fixing the movable block 6 and pulling the push block 22. The push block 22 drives the inclined surface block 19 to move inward through the connecting block 21, thereby releasing the movable block 6.
