Abstract
The utility model relates to a hand self-locking lifting device for controlling a stage curtain, a curtain and a clothes horse to lift, which is mainly composed of a rockerarm, a shell, a stranded wire wheel assembled in the shell, and a locking mechanism arranged between the stranded wire wheel and the rockerarm, wherein, the locking mechanism is composed of a transmission shaft of which one end is integrally connected with the rockerarm, a torsion spring assembled between the transmission shaft and the shell, and a convex block arranged on the stranded wire wheel. The front end of the transmission shaft is provided with a groove, and the convex block arranged on the stranded wire wheel is assembled in the groove; both end heads of the torsion spring are respectively arranged between the convex block and the groove. The lifting device has the advantage of simple and compact structure, small size and high capability; compared with the like products, the cost is reduced by more than 25%, and the service life is improved by more than six times.
Description
The utility model relates to a kind of hand self-locking type lifting device that is used to control stage curtain, curtain and clothes horse lifting.
At present, be used to control the lifter of curtain, curtain and clothes horse lifting, mostly the structure of Cai Yonging is by rocking arm, housing be assemblied in the twisted wire wheel in the housing and the lockout mechanism be located between twisted wire wheel and rocking arm is formed, its lockout mechanism mostly adopts ratchet or approach screw, very inconvenient when this kind lock mode uses, and its complex structure, volume is big, the cost height, load-carrying capacity is low.
It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, and volume is little, the hand self-locking type lifting device that can automatically lock in any position of flexible and convenient operation.
The purpose of this utility model is achieved in that this lifter comprises rocking arm, housing and is assemblied in the twisted wire wheel in the housing and is located at lockout mechanism between twisted wire wheel and rocking arm, the transmission shaft that said lockout mechanism is connected as a single entity by an end and rocking arm, be assemblied in the torsion spring between transmission shaft and the housing and the projection be located on the twisted wire wheel is formed, the front end of described transmission shaft is provided with a groove, the projection of being located on the twisted wire wheel is fitted in the groove, and the two ends of torsion spring places respectively between projection and the groove.
The torsion spring installs around between transmission shaft and housing, connects airtight between the three and touches, the gap between two ends that the two ends of torsion spring places groove to match with projection and form respectively.
One side of twisted wire wheel installs a bottom additional, and bottom is provided with a pivot pin, and pivot pin places twisted wire wheel and transmission shaft, and bottom fixedly is assemblied on the housing.
The technological advance that the utility model is obtained: under the effect of rocking arm, reel can carry out forward and reverse rotation arbitrarily, thereby can realize the lifting of clothes horse, curtain and curtain easily and flexibly.Under the effect of torsion spring, can make reel simultaneously in the lock-bit of any position.This lifter integral structure is simply compact, has reduced more than 25% than the cost of like product, and volume is little, is applicable to that less position, space installs.Load-carrying capacity improves greatly, and this lifter can be equipped with the steel wire pulling force rope, and its pulling force, elasticity, fatigue resistance and resistance to aging have tangible improvement, and improve 5 times or more than like product service life.
Be that embodiment further describes the utility model below with the accompanying drawing:
Fig. 1 is the utility model integral structure scheme drawing.
Fig. 2 is the lockout mechanism structural representation.
Fig. 3 is the left view of Fig. 2.
As shown in Figure 1, the external form of housing 1 is one hemispherical, twisted wire wheel 2 and lockout mechanism are assemblied in the housing 1, described lockout mechanism such as Fig. 2, shown in 3, the transmission shaft 4 that it is connected as a single entity by an end and rocking arm 3, torsion spring 5 and the projection of being located on the twisted wire wheel 2 are formed, the transmission shaft front end is provided with an arc groove 7, be respectively equipped with a convex edge B1 on two limits of its groove, A1, the arcuation projection of being located on the twisted wire wheel 26 is assemblied in the groove 7, torsion spring 5 installs around between transmission shaft 4 and housing 1, connect airtight between the three and touch, the discount A at torsion spring 5 two ends, the gap between two ends that B places 7 liang of convex edges of projection 6 and groove to match respectively to form, twisted wire wheel 2 rotates around a pivot pin, and this pivot pin present embodiment is assemblied on the bottom 8 that is connected with housing 1, pivot pin is through twisted wire wheel 2, and its termination places in the transmission shaft 4.Pivot pin also can be made one with transmission shaft 4, and its termination of passing twisted wire wheel 2 installs a gear pin additional, is used to limit the position of twisted wire wheel 2, also its termination can be placed in the pin hole of bottom.The working process of this lifter is as follows:
When rocking arm 3 clickwises; rocking arm 3 drives transmission shaft 4 and rotates; the convex edge B 1 on the transmission shaft 4 drives the discount B of torsion spring 5 and the contact B2 on the projection successively; make discount B produce displacement; its displacement is the static distance of discount B to projection 6 upper contact B2, because the displacement of discount B, promptly the pulling-down torque spring 5; make the reduced diameter of its torque spring 5, eliminated the friction force of 1 on torque spring 5 and shell.Thereby make rocking arm 3 drive transmission shaft 4 and twisted wire wheel 2 and the unresisted clockwise rotation of wire sling successively.When rocking arm 3 rotated counterclockwise, its working process and above-mentioned difference were that convex edge A1 drives discount A and contact A 2 successively, realizes that non-resistance rotates counterclockwise.
When the needs lock-bit, the rotation that stops rocking arm 3 can realize.Its working process is as follows: because the effect of loads on the wire sling, through wire sling and twisted wire wheel 2, to producing an application force for the B2 that touches on the projection 6 of one with twisted wire wheel 2, this application force drives discount B and convex edge B1 successively by touching a B2, make discount B produce displacement, the displacement of its discount B is that discount B is to the static distance between the convex edge, because the anti-phase displacement of discount B, promptly push away the torque spring 5 that rises, the external diameter of its torque spring 5 is risen greatly, make that the friction force between torque spring 5 and shell infinitely increases.Thereby can realize twisted pair wire wheel 2 automatically locking in any position.
