Abstract
The invention provides a kind of folding and unfolding controlling mechanism, comprise a package and be arranged in the rotating shaft of the end in package with knob, it is characterized in that: described rotating shaft is distributed with one section of left-handed thread spaced apart from each other and one section of right-handed thread vertically, described left-handed thread and right-handed thread are bolted with swivel nut respectively, swivel nut in described left-handed thread is connected with the end head of two tow ropes stretched in package respectively with the swivel nut on right-handed thread, axial limiting is realized by axial limiting assembly between described rotating shaft and package, described tow rope is arranged in rope sling, the tow rope that package end face can be inserted in the termination of described rope sling penetrates this mechanism in hole and can realize a tow rope by a spinning movement simultaneously and rise and the action of a tow rope decline, organization establishes is reasonable, easy to operate.
Description
Technical field
The present invention relates to a kind of regulator, particularly the two-way folding and unfolding controlling mechanism of one.
Background technique
Existing employing screw rod carries out the mechanism of folding and unfolding adjustment; for being arranged at the rope reeling mechanism of screw rod linkage on screw rod; lifting rope, by being placed in the chain-driving screw rod of drive screw turns can rotate and carry out rope closing and put the action of rope outside screw rod, can only carrying out the gathering of rope or decontrol the action in a direction.
Summary of the invention
The present invention is directed to above problem, propose a kind of two-way folding and unfolding controlling mechanism, this mechanism can realize by a spinning movement action that a tow rope rises and a tow rope declines simultaneously, and organization establishes is reasonable, easy to operate.
Technical program of the present invention lies in: a kind of two-way folding and unfolding controlling mechanism, comprise a package and be arranged in the rotating shaft of the end in package with knob, it is characterized in that: described rotating shaft is distributed with one section of left-handed thread spaced apart from each other and one section of right-handed thread vertically, described left-handed thread and right-handed thread are bolted with swivel nut respectively, swivel nut in described left-handed thread is connected with the end head of two tow ropes stretched in package respectively with the swivel nut on right-handed thread, axial limiting is realized by axial limiting assembly between described rotating shaft and package, swivel nut in described left-handed thread and the swivel nut on right-handed thread one of them contact with package upper inside surface and slide, another contacts with package lower inner surface and slides, described tow rope is arranged in rope sling, the tow rope that package end face can be inserted in the termination of described rope sling penetrates in hole.
The invention has the advantages that: this mechanism member is simple, arrange rationally, drive screw rod rotation can realize receipts one by rotation knob and put two actions, design ingenious; This mechanism is applied widely, can be used for suspending the angular adjustment of plate, the folding and unfolding etc. of suspention article in midair, and it is very convenient to operate.

Embodiment
A kind of two-way folding and unfolding controlling mechanism, comprise a package 1 and be arranged in the rotating shaft 3 of the end in package with knob 2, it is characterized in that: described rotating shaft is distributed with one section of left-handed thread 4 spaced apart from each other and one section of right-handed thread 5 vertically, described left-handed thread and right-handed thread are bolted with swivel nut 6 respectively, the end head 8 of the tow rope 7 that the swivel nut in described left-handed thread and the swivel nut on right-handed thread stretch in package with two is respectively connected, axial limiting is realized by axial limiting 9 assembly between described rotating shaft and package, swivel nut in described left-handed thread and the swivel nut on right-handed thread one of them contact with package upper inside surface and slide, another contacts with package lower inner surface and slides, prevent two swivel nuts in opposite directions or reversing motion time two tow ropes interfere with each other, described tow rope is arranged in rope sling 13, the tow rope that package end face can be inserted in the termination 18 of described rope sling penetrates in hole, rope sling is flexible rope sling, can pull to any direction.
The upper and lower end portion of described package, respectively in arch, coordinates slide, in order to limit the axial-rotation of swivel nut in order to contacting arch position with swivel nut upper and lower.
The upper end portion of described swivel nut or the arch end face of underpart offer in order to tow rope through the draw-in groove 10 that also can block tow rope end head, tow rope is stuck between the arch end face of draw-in groove and package, and when guaranteeing pulling traction rope, tow rope can not be deviate from from swivel nut.
Described knob is the knob that connecting end has interior hexagon chamber 11, and described interior hexagon chamber coordinates with the hexagon connecting end 12 of rotating shaft, arranges knob and is convenient to carry out rotation process.
Described axial limiting assembly comprises the circular groove 14 that rotating shaft is offered near knob side, position corresponding with circular groove on housing front and back sides offers respectively the aperture 15 run through, one U-shaped bayonet lock 16 passes aperture and is stuck in the circular groove of rotating shaft, upon rotation of the knob, the axial motion of screw rod is limited, and can only do and rotate running.
Now for embodiment, working procedure of the present invention is described: turn clockwise knob, knob drives screw rod to turn clockwise, right-handed thread on screw rod makes the swivel nut be mated to left movement, tow rope is relaxed, its suspension heavy weight does descending motion under Gravitative Loads, left-handed thread makes the swivel nut be mated move right simultaneously, and tow rope is stretched, and the weight driving it to suspend in midair rises; Otherwise, be rotated counterclockwise knob, knob drives screw rod to be rotated counterclockwise, left-handed thread on screw rod makes the swivel nut be mated to left movement, tow rope is relaxed, and its suspension heavy weight does descending motion under Gravitative Loads, and right-handed thread makes the swivel nut be mated move right simultaneously, tow rope is stretched, and the weight driving it to suspend in midair rises; The action rotated by one like this, can rise by synchronization control tow rope, a tow rope declines.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
