[0026] The hose reel auxiliary device of the present application is installed on the outside of the hose reel bracket, the hose reel includes a hose reel and a bracket, and the device is connected to the gear transmission on the hose reel through a transmission member;

[0027] The object to be wound in the present application is a hose for transmitting gas or liquid, or an electric wire, or a warning tape, etc.

[0028] like Figure 1-5 As shown, an embodiment of the present application provides a hose reel auxiliary device, including a housing 1, a groove 11 is formed on one side of the housing 1, a cover 12 is provided at the opening corresponding to the groove 11, and the cover 12 is connected to the housing 1;

[0029] A transmission member 3, which is arranged on the other side of the housing 1;

[0030] The speed reduction mechanism 2 includes a rotating disk 21 and a plurality of speed reduction members 22. The rotating disk 21 is slidably sleeved on the outer wall of the connecting member 4. The speed reduction members 22 are detachably and rotatably mounted on the outer peripheral edge of the rotating disk 21.

[0031] The housing 1 , the rotating disk 21 and the transmission member 3 are connected via a connecting member 4 , and the housing 1 , the rotating disk 21 , the transmission member 3 and the connecting member 4 are coaxially arranged.

[0032] In this embodiment, the connection between the cover body 12 and the housing 1 is a snap connection or a threaded connection. An end of the connecting member 4 close to the transmission member 3 is provided with an internal thread and is threadedly connected with a fastening nut 41. A through hole is provided at the axial position of the transmission member 3. The fastening thread penetrates the transmission member 3 and extends into the interior of the housing 1 to connect with the connecting member 4. Optionally, the transmission member 3 is a gear or a friction wheel.

[0033] The turntable 21 can only slide on the connecting member 4 and cannot rotate. When the connecting shaft drives the turntable 21 to rotate at a high speed, under the action of centrifugal force, the speed reducer 22 will open in the direction away from the turntable 21, contact the side wall of the groove 11 in the housing 1, and slide on the side wall of the groove 11. At this time, under the action of friction, the sliding speed of the speed reducer 22 on the side wall of the groove 11 will be reduced, resulting in a reduction in the speed of the turntable 21, the connecting member 4, and the transmission member 3, thereby achieving the purpose of limiting the pulling-out speed and the recovery speed of the winding member to be wound;

[0034] By setting up the deceleration mechanism 2, when the member to be wound is recovered, the deceleration mechanism 2 will decelerate the rotation speed of the connecting member 4 when the rotation speed of the connecting member 4 for recovering the member to be wound is too fast, thereby reducing the recovery speed of the member to be wound, preventing the end of the member to be wound from swinging irregularly due to the too fast recovery speed, causing harm to the user or surrounding objects, and improving the safety of the pipe reel.

[0035] In one embodiment, the rotating disk 21 and the connecting member 4 are detachably connected.

[0036] In this embodiment, the rotating disk 21 and the connecting member 4 are snap-connected, and the rotating disk 21 can only slide on the connecting member 4 but cannot rotate.

[0037] In one embodiment, the number of the speed reducers 22 is at least two, and the speed reducers 22 are arranged in a circular array on the edge of the turntable 21 .

[0038] In this embodiment, the number and contact area of ​​the deceleration members 22 can be selected according to the size of the hose reel spring force to achieve the recovery speed required by the user, and the deceleration members 22 are arranged in a circular array on the edge of the turntable 21, which can improve the rotation stability of the turntable 21.

[0039] In one embodiment, the deceleration member 22 includes a deceleration block 222 and a rotating shaft 221 . A fourth notch 211 is formed on the edge of the rotating disk 21 . The rotating shaft 221 is movably inserted into the fourth notch 211 . The deceleration block 222 is fixedly connected to the side wall of the rotating shaft 221 .

[0040] In this embodiment, under the action of centrifugal force, the speed reduction block 222 will continuously open in a direction away from the rotating disk 21 and close in a direction close to the rotating disk 21 , thereby driving the rotating shaft 221 to rotate in the fourth notch 211 .

[0041] In one embodiment, the center of gravity of the speed reduction block 222 is offset from the plane where the axis of the rotating disk 21 and the axis of the rotating shaft 221 are located.

[0042] In this embodiment, by setting the center of gravity of the speed reduction block 222 to be offset from the plane where the axis of the turntable 21 and the axis of the rotating shaft 221 are located, when the turntable 21 rotates in the direction opposite to the offset direction, the speed reduction block 222 will be retracted, and when the speed reduction block 222 rotates in the direction opposite to the offset direction, the speed reduction block 222 will be opened.

[0043] In one embodiment, a clamping block 223 is disposed at one end of the rotating shaft 221 .

[0044] In this embodiment, by providing a clamping block 223 at one end of the rotating shaft 221 , it is possible to prevent the rotating shaft 221 from sliding inside the clamping block 223 when the rotating disk 21 rotates at a high speed.

[0045] The working principle of the hose reel auxiliary device of this application is as follows:

[0046] When the pulling speed is too fast, resulting in an excessively fast rotation speed of the hose reel, the deceleration block 222 in the deceleration mechanism 2 contacts the inner wall of the groove 11 of the housing 1 under the action of centrifugal force and slides on the inner wall of the groove 11, and the rotation speed of the connecting member 4 is reduced under the action of friction, thereby reducing the rotation speed of the hose reel;

[0047] When the wound component needs to be recovered, if it is recovered too quickly, resulting in an excessively fast rotation speed of the reel, the deceleration block 222 in the deceleration mechanism 2 contacts the inner wall of the groove 11 of the shell 1 under the action of centrifugal force and slides on the inner wall of the groove 11. Under the action of friction, the rotation speed of the reel is reduced, allowing the wound component to be safely recovered.

[0048] This embodiment provides a hose reel, comprising the hose reel auxiliary device of any one of the above embodiments.

[0049] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
