Description

Technical Field

[0001] The utility model relates to the technical field of hose retraction and deployment, in particular to a pneumatic hose retraction and deployment device. Background Art

[0002] There are many varieties of pneumatic pressure hoses, which are generally produced with PU raw materials. They have stable quality, are resistant to high pressure, weather, wear, and tortuosity. The tube body is smooth and flexible, with bright colors, high elasticity, resistance to bending, and a small bending radius.

[0003] Existing pneumatic pressure hoses are often wrapped around retractable rollers. When using the pneumatic pressure hose, the retractable roller is first placed on a fixed rod, and then one end of the pneumatic pressure hose is pulled to drive the retractable roller to rotate, thereby realizing the hose release operation. Among them, firstly, it is difficult to find a suitable fixed rod to make the retractable roller rotate regularly in different working environments; secondly, when the hose needs to be stretched too long, pulling one end of the hose to move can easily damage the hose, and it is inconvenient to retract and release.

When in use, the storage roller 201 is placed into the storage box 1, and the movable side panel 102 is closed to form a closed box body, which is convenient for people to carry and move; at the same time, when different types of pneumatic hoses 202 need to be replaced, the movable side panel 102 can be conveniently opened to replace different types of pneumatic hoses 202; a storage through groove 103 is provided to expose one end of the pneumatic hose 202 from the storage through groove 103, which is convenient for connecting the required equipment.

[0052] like Figures 1 to 6 As shown, the placement portion includes: a rotating sleeve 301, one end of which is connected to the box side plate 101, and the inner wall of the other end is provided with a thread to be threadedly connected to the clamping portion.

[0053] like Figures 1 to 6 As shown, the driving part includes: a second turning handle 304, which passes through the box side plate 101 and is fixedly connected to one end of the rotating sleeve 301 to drive the rotating sleeve 301 to rotate.

[0054] In the embodiment of the present invention, the second turning handle 304 is manually rotated to drive the rotating sleeve 301 to rotate. The rotating sleeve 301 is threadedly connected to the clamping portion, thereby driving the retractable roller 201 to rotate simultaneously through the clamping portion.

[0055] like Figures 1 to 6 As shown, the clamping part includes: a second sleeve 408, which is sleeved on the rotating sleeve 301; four groups of telescopic parts are provided, and the four groups of telescopic parts are circumferentially arranged on the second sleeve 408 to clamp the retracting rollers 201 of different sizes; four groups of limiting parts are provided, and the four groups of limiting parts and the four groups of telescopic parts are correspondingly arranged on the rotating sleeve 301, and are connected to the telescopic parts to limit the movement of the telescopic parts; a second driving part is connected to the other end of the rotating sleeve 301, and is fixedly connected to the second sleeve 408 to drive the second sleeve 408 to move.

Since four groups of extrusion plates 404 extending in four different directions are provided at the same time, the retracting roller 201 is clamped from the inside to the outside, thereby fixing the position of the retracting roller 201.

[0060] Among them, the retracting rollers 201 with different inner diameters can be fixed by rotating the first handle 303 to different degrees. At the same time, for retracting rollers 201 with different widths, the center of the retracting roller 201 can be aligned with the retracting groove 103 through manual adjustment to facilitate the retraction and extension of the pneumatic hose 202.

[0061] Working principle: When in use, the movable side panel 102 is opened manually, and then the designated retractable roller 201 is sleeved on the extrusion plate 404. The position of the retractable roller 201 is determined manually according to the width of the retractable roller 201. Then, the first turning handle 303 is manually rotated to drive the threaded shaft 302 to move inward along the inner wall of the rotating sleeve 301, thereby driving the second sleeve 408 and the first turning handle 303 to move toward the box side panel 101, thereby driving the second fixed plate 407 to move toward the box side panel 101, so that the second fixed plate 407 drives the first fixed plate 405 to extend outward through the hinge shaft 406, and at the same time drives the limiting slider 403 to slide in the sliding limiting groove 402, thereby 3 and drives the first fixed plate 405 to extend outward, driving the squeezing plate 404 to extend outward regularly. Since four groups of squeezing plates 404 extending in four different directions are provided at the same time, the retracting roller 201 is clamped from the inside to the outside, thereby fixing the position of the retracting roller 201. At this time, the movable side plate 102 is closed to form a closed box body, which is convenient for people to carry and move. By rotating the second turning handle 304, the rotating sleeve 301 is driven to rotate, and the rotating sleeve 301 drives the retracting roller 201 to rotate through the threaded shaft 302, the second sleeve 408, the second fixed plate 407, the hinge shaft 406, the first fixed plate 405 and the squeezing plate 404, thereby retracting and releasing the pneumatic hose 202 wound on the retracting roller 201.
