Problems solved by technology

[0006] The existing automatic hose reel for storing hoses or cables is provided with a quarter-circumference arc rack on the rotating lower plate, and a pinion gear meshed with it is provided on the lower shell, and at the same time There is a toggle lever with a part of the gear next to the pinion, which can only be toggled to work when the turntable is in a certain position. In use, the mainspring sometimes retracts too fast when retracting the hose or cable. Excessive force will cause the hose or cable to swing like cosine waves and Fourier curves during the process of retracting the hose or cable, which sometimes causes personal injury and damage to the hose or cable and joints; in addition, The existing automatic hose reels also have the problems of difficulty in controlling the operation of locking the hose or cable during use and insufficient reliability and stability

Embodiment Construction

[0066]The operator first fixes a bracket that can be rotated slightly within 180 degrees through a long pin connection on the outer shell of a tube winding device with various damping mechanisms; because the groove on the shaft of the stationary inner disc is equipped with a coil spring One end of the center of circle of clockwork spring, the outer circle of coil spring spring is contained on the card post at the edge place of the main wheel (14) of rotation, and block with the four places of upper big plate by edge, so big gear does not move. When pulling the pipeline, because the main wheel 14 is equipped with a pipe joint, the pipeline (113) has been installed on the pipe joint, and the pipeline and the retaining ball (95) are passed through the rowing hand (107) of the pipe rower. It is wound on the main wheel, and the main wheel and the lower plate are fixed and integrated by screws, and the center tube shaft of the lower plate is rotated and inserted into the smooth outer...

Abstract

A hydrodynamic traveling hose reel with logarithmic spiral grooves is characterized in that a position lock with a lock device is of a crank pin (10) which is run by internal and external cam grooveswith far and near multiple controlling points along the plane, spirals containing curvature and contingence angle away from a circle center adopt higher mathematics approximate similar Archimedes spirals (3aa) as internal grooves (3n), and spirals containing curvature and contingence angle away from the circle center of external ring grooves (3g) of the external cam grooves only adopt equiangularspirals of higher mathematics function curves with characteristics of pressure angles being equal everywhere, that is logarithmic spirals (3cc), to be more suitable for forming the internal and external cam grooves with the far and near multiple controlling points to run the crank pin (10), so that more smooth operation without occasional stuck is facilitated, the reliability of products is greatly improved, and an international problem of occasional failure is solved.

Description

technical field [0001] The present invention relates to the technical field of the retracting device of the pipeline winder, in particular to a further improved logarithmic spiral groove reel tube for a water-powered walker with a position lock mechanism for damping hoses or cables device. Background technique [0002] The existing automatic hose reel for storing hoses or cables is provided with a quarter-circumference arc rack on the rotating lower plate, and a pinion gear meshed with it is provided on the lower shell, and at the same time There is a toggle lever with a part of the gear next to the pinion, which can only be toggled to work when the turntable is in a certain position. In use, the mainspring sometimes retracts too fast when retracting the hose or cable. Excessive force will cause the hose or cable to swing like cosine waves and Fourier curves during the process of retracting the hose or cable, which sometimes causes personal injury and damage to the hose or ...
