Abstract
The utility model relates to a one-hand operating device for a semiautomatic umbrella, comprising a casing, a pull rope, a handle and a ratchet mechanism and fixed on the lower part of the umbrella rod of the semiautomatic umbrella via spiral ropes. When the handle is pressed, the pull rope is wound on a reel under the action of the ratchet mechanism to close the umbrella. When the umbrella needs to be opened, the shifting lever of a ratchet is pressed by hand, and the umbrella is opened automatically. The one-hand operating device enables the umbrella to have the one-hand operating function without changing the existing umbrella crown structure of the semiautomatic umbrella, solves the defect of inconvenient use of the semiautomatic umbrella and has simple structure and convenient operation.
Description
The utility model relates to the singlehanded headstock gear of semi-automatic umbrella.
At present, the semi-automatic umbrella of producing or selling no matter be stock or folding, can only eject automatically, needs two hands to work simultaneously and can regain during withdrawal, makes troubles people's development and production full automatic umbrella again for this reason, its complex structure, cost height to use.Chinese patent CN90219964 provides a kind of one-handed performance full-automatic en-toutcas, rely on gear mechanism and stay cord to realize when opening and closing umbrella, but the umbrella header structure of this umbrella is different with the semi-automatic umbrella of producing at present, and complex structure is not so this headstock gear is suitable on the semi-automatic umbrella.
The purpose of this utility model is to provide a kind of singlehanded headstock gear, can be installed on the semi-automatic umbrella of present production, substitutes original umbrella handle, makes semi-automatic parachute kit that the singlehanded function that opens and closes be arranged, and does not change the umbrella header structure of former semi-automatic umbrella, and cost is low.
For achieving the above object, the utility model is realized by following structure.
The singlehanded headstock gear of semi-automatic umbrella is made up of housing, stay cord, handgrip, ratchet mechanism, is fixed on semi-automatic umbrella umbrella bar bottom with nut.Three Xiao's axles are housed on housing, one is ratchet shaft, one is ratchet driving lever Xiao, ratchet and reel sub-assembly and a driven slip gear are housed on ratchet shaft, between reel assembly and driven slip gear, uni-directional brake is housed, the ratchet driving lever is installed in reel assembly top by driving lever Xiao, torsion spring is housed on the driving lever, the ratchet of driving lever one end and the ratchet engaged on the reel assembly, be installed in the handgrip of the band torsion spring on handgrip Xiao, its extension is an arc-shaped rack, and tooth bar is meshed with driven friction pulley, stay cord one end is fixed on the umbrella stand, and the other end is on reel.
Be installed between reel assembly and the driven slip gear uni-directional brake as shown in drawings, form by outer ring, stem stem, steel ball, outer ring and reel assembly one, be contained in the cavity of reel one end, stem stem is provided with the skewed slot of radius unequal, steel ball is installed in the skewed slot, and the stem stem other end is driven slip gear.
For further specifying the structure of this utility model, described below in conjunction with accompanying drawing.
The singlehanded headstock gear structural representation of the semi-automatic umbrella of Fig. 1
The singlehanded headstock gear cutaway view of the semi-automatic umbrella of Fig. 2
Among the figure: 15 driven slip gear 16 ratchet shafts 17 steel balls of 1 handgrip Xiao, 2 handgrip torsion springs, 3 handgrips, 4 top cord rings, 5 ratchet driving levers, 6 spline Xiao, 7 clamp nuts, 8 finer wire stay cords, 9 driving lever torsion springs, 10 ratchet driving lever Xiao, 11 ratchet reel assemblies, 12 copper sheathings, 13 housing fastening bolts, 14 uni-directional brake outer rings
The course of work of the present utility model is as follows:
When this headstock gear closes one's umbrella, press handgrip, the arc-shaped rack on the handgrip drives driven gear and rotates, driven slip gear drives stem stem, stem stem drives steel ball, and steel ball drives the outer ring, and outer ring and ratchet reel assembly rotate, umbrella is packed up in coiling, after pressing handgrip, handgrip is by the torsion spring return, and ratchet does not turn round by the effect of driving lever ratchet, press again handgrip, arc-shaped rack drives driven slip gear again and rotates, and by former direction coiling, works so successively about four times, umbrella can be packed up, finger unclamps and presses handgrip during parachute-opening, holds the handle of umbrella handle, presses the ratchet driving lever, the same with first automatic umbrella parachute-opening principle of present market, automatically open.
Advantage of the present utility model:
After semi-automatic umbrella is installed this device, can singlehandedly open and close umbrella, solve in use inconvenient defective of semi-automatic umbrella. This headstock gear can be recovered to any centre position to umbrella, all umbrella can be opened as long as press ratchet switch in any position. It is simple in structure. And need not change former umbrella head structure.
Embodiment:
Long 110～the 120mm of shell of the present utility model, wide 45～55mm, thick 24～26mm.Can be used as umbrella handle uses.
Shell, reel assembly, ratchet driving lever are casting spare.
Handgrip, driven slip gear are stamping parts.
