Abstract
The utility model discloses an elevating mechanism. A screw rod capable of rotating around axial line of the mechanism is arranged on a pedestal. A sliding block is matched with screw thread of the screw rod. One end of a stayguy is connected with the sliding block after swinging around a fixed block. The utility model can realize the lifting operation of small weight with a simple structure. In addition, the self-locking effect of the screw can allow the heavy object retaining under the suitable position without using additional positioning devices.
Description
Technical field
The utility model relates to a kind of lifting mechanism.
Background technology
Occasion in the installation of heavy wares need often be used lift system, as in the prior art, stay cord (commonly used is steel rope) is walked around pulley, weight is hung on the end of stay cord, the other end affects stay cord by motor or other mechanism and weight is promoted, but this structure is mainly used in the occasion of heavy wares lifting, the complex structure of whole lifting mechanism; And in the relative lighter occasion of weight weight, as in teaching equipment, need flat screens is installed, adopt above-mentioned lifting mechanism and improper this moment, be difficult to realize and depend merely on manpower, and weights such as flat screens are risen to after the correct position, can't easily its position be fixed again.
So, need design a kind of lifting mechanism between heavy lifting mechanism and manpower lifting.
Summary of the invention
The purpose of this utility model is to provide a kind of lifting mechanism simple in structure, easy to use.
The utility model is achieved through the following technical solutions:
A kind of lifting mechanism can be located on the pedestal around the screw mandrel of its axis rotation, and slide block cooperates with wire rod thread, and after stay cord was walked around fixed pulley, wherein an end was connected with slide block.
By rotary screw rod, because screw mandrel and slide block be by screw thread fit, slide block just endwisely slips and affects the wherein end of stay cord along screw mandrel, and stay cord is walked around after the pulley, and the other end will heavily claim lifting; The utility model total is very simple, is convenient for carrying, and is applicable to the occasion that general weight promotes; Promote weight owing to drive stay cord by screw mandrel, after screw mandrel stopped operating, because the self-locking action of screw thread, weight just rested on this position, and does not need additionally to set up an organization weight is positioned.
Further improvement of the utility model is:
Described fixed pulley is at least two at least two, described stay cord; After at least two described stay cords were walked around one of them described fixed pulley respectively, wherein an end was connected with described slide block.By two fixed pulleys weight is promoted, the balance of weight is improved.
The other end of described stay cord is connected with described pedestal after walking around movable pulley; Weight finally acts on described movable pulley.After the employing movable pulley, the pulling force that stay cord is born reduces half.
Described screw mandrel and rocking handle be circumferential captives joint and is driven by this rocking handle.Drive the screw mandrel rotation and weight is promoted by hand rocking handle, simple in structure, be convenient for carrying, be applicable to the lifting of small-sized weight, range of use is wide.
Described screw thread is square thread or Acme thread.The resistance of square thread, Acme thread is little.
Be provided with guide rail on described pedestal, described slide block can slide along this guide rail.Guide rail and pedestal can be the branch body structure, also can be integrative-structures.
To sum up, the utility model has the advantages that:
1, simple in structure, be convenient for carrying, and can be applicable to occasion easily the lifting of small-sized weight;
2, at least two stay cords promote weight, and the balance of weight is improved;
3, by adopt fixed pulley can be easily to the dip direction of stay cord;
4, by adopting movable pulley can reduce the pulling force that stay cord bears;
5,, realize the screw thread self-locking and weight stayed in correct position and do not need the extra means location by the screw thread fit between screw mandrel and the slide block.

The specific embodiment
Embodiment one: see also Fig. 1, Fig. 2, a kind of lifting mechanism, can be located on the pedestal 3 around the screw mandrel 1 of its axis rotation, slide block 2 and screw mandrel 1 screw thread fit (its screw thread can adopt square thread or Acme thread), pedestal 3 is provided with guide rail 8, and slide block can slide in guide rail 8, after stay cord 4 is walked around fixed pulley 5, wherein an end is connected with slide block 2, and the other end of stay cord 4 is connected with pedestal 3 after walking around movable pulley 6; Weight finally acts on this movable pulley 6; Screw mandrel 1 is circumferentially captiveed joint with rocking handle 7 and is driven by this rocking handle 7.
When using present embodiment, hand rocking handle 7 drives screw mandrels 1 rotation, because screw mandrel 1 and slide block 2 screws thread fit, slide block 2 endwisely slips and affects stay cord 4 along screw mandrel 1, and stay cord 4 is by promoting movable pulley 6, and weight is mentioned; When weight reaches proper height, stop to shake of rocking handle 7, owing to the self-locking action of screw thread makes weight rest on proper height.
Embodiment two:
See also Fig. 3, the difference of present embodiment and embodiment one is: it is two that fixed pulley 5, movable pulley 6 are two, stay cord 4; After two stay cords 4 were walked around one of them fixed pulley 5 respectively, wherein an end was connected with slide block 2, and the other end is connected with pedestal 3 after walking around one of them movable pulley 6 respectively; Weight finally acts on movable pulley 6.In the present embodiment, promote weight by two stay cords 4, the balance of weight is better.
