The structure of the existing hose reel mainly includes a shell, a reel is set in the shell, a hose is wound around the reel, and a coil spring is connected to the reel. When the hose is pulled out, the hose will drive the reel to rotate. The reel drives the coil spring to tighten and store pressure. When the hose is released, the coil spring will drive the reel to rotate back under the action of the restoring force, and the reel drives the hose to retract into the shell. This structure has no impact on the hose or The reel deceleration device causes the hose to retract too fast and too violently, causing the hose to swing like a cosine wave and a Fourier curve during the retraction process, posing a certain safety hazard

Embodiment Construction
[0023] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0024] see figure 1 As shown, it is a structural schematic diagram of the reel in the automatic retraction deceleration device of the hose reel of the present invention; the hose reel includes a base 1, the base 1 is a symmetrical structure, and there are multiple installations on the left and right sides hole 11 for fixing the hose reel, figure 1 As shown in , the number of the installation holes 11 is four, and they are arranged symmetrically. The upper surface of 1 is symmetrically provided with two support arms 2, and the support arms 2 are in the shape of "7". Easy to bend, the opposite side of the support arm 2 is hollow, which not only reduces the weight of the support arm 2, but also does not affect the strength and rigidity of the support arm 2; an automatic retraction deceleration is provided b...

The invention provides an automatic shrinkage speed reducing device of a pipe winder. The automatic shrinkage speed reducing device is divided into a left shell and a right shell, wherein two stand columns are respectively arranged on the left and right shells; and the positions of the stand columns on the left shell are corresponding to the positions of the stand columns on the right shell. The automatic shrinkage speed reducing device further comprises a coil spring, wherein the coil spring is positioned between the left and right shells; cavities are respectively formed in the outer sides of the left and right shells; and small gears are arranged in the cavities, are mounted on rotating shafts through square keys, and synchronously rotate with the left and right shells. The automatic shrinkage speed reducing device further comprises a large gear; and the large gear is engaged with the small gears to form a speed reducing mechanism. The automatic shrinkage speed reducing device further comprises two belt wheels; and one ends of the belt wheels are connected with an output shaft of the large gear, and the other ends are contacted with the left and right shells. The automatic shrinkage speed reducing device uses the large and small gears for forming the speed reducing mechanism, and uses the left and right shells and the belt wheels for forming a speed reduction circulating mechanism, so that the phenomenon of over-fast and over-strong shrinkage of pipes cannot be generated in the shrinkage of the pipes.
Description
technical field [0001] The invention relates to a deceleration device, in particular to an automatic retraction deceleration device for a hose reel. Background technique [0002] The hose reel, also known as the wire winder, winds the pipe or wire on a shaft, and it can be retracted automatically after being pulled out. It is simple and practical. widely used. The structure of the existing hose reel mainly includes a shell, a reel is set in the shell, a hose is wound around the reel, and a coil spring is connected to the reel. When the hose is pulled out, the hose will drive the reel to rotate. The reel drives the coil spring to tighten and store pressure. When the hose is released, the coil spring will drive the reel to rotate back under the action of the restoring force, and the reel drives the hose to retract into the shell. This structure has no impact on the hose or The reel deceleration device causes the hose to retract too fast and too fast, causing the hose to swin...
