Abstract

The invention provides a withdrawing and releasing adjusting mechanism which comprises a tube and a rotary shaft. The rotary shaft is penetratingly arranged in the tube, and a button is arranged at an end of the rotary shaft. The withdrawing and releasing adjusting mechanism is characterized in that left-handed threads and right-handed threads which are separated from each other are axially distributed on the rotary shaft, swivel nuts are respectively in screw connection with the left-handed threads and the right-handed threads, the swivel nut on the left-handed threads and the swivel nut on the right-handed threads are respectively connected with ends of two traction ropes extending into the tube, the rotary shaft and the tube are axially limited relatively by an axial limiting component, the traction ropes are penetratingly disposed in rope sleeves, and an end of each rope sleeve can be inserted into a traction rope penetrating hole on the corresponding end surface of the tube. One traction rope can ascend while the other traction rope descends via one action of rotation by the aid of the mechanism, and the mechanism is reasonable in arrangement and convenient to operate.

Description

A kind of two-way folding and unfolding controlling mechanism

Technical field

The present invention relates to a kind of regulator, particularly a kind of two-way folding and unfolding controlling mechanism.

Background technique

Existing employing screw rod carries out the mechanism that folding and unfolding is regulated; For on screw rod, being arranged at the rope drawing machine structure of screw rod interlock; But lifting rope drives the action that the screw rod rotation is received rope and put rope through the chain that places the outer drive screw turns of screw rod, can only carry out the gathering of rope or decontrol the action of a direction.

Summary of the invention

The present invention is directed to above problem, proposed a kind of two-way folding and unfolding controlling mechanism, this mechanism can realize simultaneously that through a spinning movement tow rope rises and the action that tow rope descends, and mechanism is provided with rationally, and is easy to operate.

Technical program of the present invention lies in: a kind of two-way folding and unfolding controlling mechanism; Comprise that the package end interior with being arranged in package has the rotating shaft of knob; It is characterized in that: said rotating shaft is distributed with one section left-handed thread spaced apart from each other and one section right-handed thread vertically; Be bolted with swivel nut on said left-handed thread and the right-handed thread respectively, the swivel nut on the said left-handed thread is connected with two termination portions that stretch into the tow rope in the package respectively with swivel nut on the right-handed thread, realizes axial limiting through the axial limiting assembly between said rotating shaft and the package; One of them contacts swivel nut on swivel nut on the said left-handed thread and the right-handed thread with the package upper inside surface and slides; Another contacts with the package lower inner surface and slides, and said tow rope is arranged in the rope sling, and the tow rope that the package end face can be inserted in the termination of said rope sling penetrates in the hole.

The invention has the advantages that: this mechanism member is simple, is provided with rationally, drives the screw rod rotation through rotary knob and can realize that one receives one and puts two actions, designs ingenious; This mechanism's Applicable scope is extensive, can be used for suspending in midair the angular adjustment of plate, the folding and unfolding of suspention article etc., and operation is very convenient.

Embodiment

A kind of two-way folding and unfolding controlling mechanism; Comprise that a package 1 end interior with being arranged in package has the rotating shaft 3 of knob 2; It is characterized in that: said rotating shaft is distributed with one section left-handed thread 4 spaced apart from each other and one section right-handed thread 5 vertically, is bolted with swivel nut 6 on said left-handed thread and the right-handed thread respectively, and the swivel nut on the said left-handed thread is connected with two termination portions 8 that stretch into the tow rope 7 in the package respectively with swivel nut on the right-handed thread; Realize axial limiting through axial limiting 9 assemblies between said rotating shaft and the package; One of them contacts swivel nut on swivel nut on the said left-handed thread and the right-handed thread with the package upper inside surface and slides, and another contacts with the package lower inner surface and slides, prevent two swivel nuts in opposite directions or during reversing motion two tow ropes interfere with each other; Said tow rope is arranged in the rope sling 13; The tow rope that the package end face can be inserted in the termination 18 of said rope sling penetrates in the hole, and rope sling is flexible rope sling, can spur to any direction.

The upper and lower end portion of said package is arch respectively, in order to cooperating slip with the upper and lower arch position that contacts of swivel nut, in order to the axial rotation of restriction swivel nut.

Offer the draw-in groove 10 that passes and can block tow rope termination portion in order to tow rope on the arch end face of the upper end portion of said swivel nut or underpart; Tow rope is stuck between the arch end face of draw-in groove and package, and tow rope can not deviate from from swivel nut when guaranteeing pulling traction rope.

Said knob is the knob that connecting end has interior hexagon chamber 11, and said interior hexagon chamber cooperates with the hexagon connecting end 12 of rotating shaft, knob is set is convenient to be rotated operation.

Said axial limiting assembly comprises the circular groove 14 that rotating shaft is offered near knob one side; Offer the aperture 15 that runs through respectively on the position corresponding on the housing front and back sides with circular groove; One U type bayonet lock 16 passes aperture and is stuck in the circular groove of rotating shaft; When rotary knob, the axial motion of screw rod is limited, and can only do the rotation running.

Existing is that example is explained working procedure of the present invention with embodiment: knob turns clockwise; Knob drives screw rod and turns clockwise, and the right-handed thread on the screw rod makes the swivel nut that is mated to left movement, and tow rope is loosened; Its suspension heavy weight is done descending motion under the deadweight effect; Left-handed thread moves right the swivel nut that is mated simultaneously, and tow rope is stretched, and drives its weight that suspends in midair rising; Otherwise, being rotated counterclockwise knob, knob drives screw rod and is rotated counterclockwise; Left-handed thread on the screw rod makes the swivel nut that is mated to left movement; Tow rope is loosened, and its suspension heavy weight is done descending motion under the deadweight effect, and right-handed thread moves right the swivel nut that is mated simultaneously; Tow rope is stretched, and drives its weight that suspends in midair rising; Pass through the action of a rotation like this, but tow rope of synchronization control rises a tow rope decline.

The above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
