Abstract
An elevating device can position a corner. One end of a handle of the elevating device is fixedly connected with one end of a push rod, another end of which is provided with a U-shaped slot. The push rod and one end of a guide rod are linked inside the U-shaped slot by the pattern of hinge joint. A soleplate is provided with a knuckle bearing, and the guide rod is put through the soleplate and is synchronously articulated at the knuckle bearing. A tension spring is fixed at the middle part of the push rod, and another end of the tension spring is put through the soleplate and is connected with the terminal end of a guide slot, which is fixed at the bottom of the soleplate. The terminal end of the guide slot is also connected with a pressure spring, another end of which is connected with the guide rod, which is put through the guide slot. An outside cylinder is provided with a blocking plate and a sleeve of the blocking plate. The blocking plate and the sleeve of the blocking plate are arranged as interference fit. The sleeve of the blocking plate also meshes the soleplate, and the sleeve of the blocking plate and the soleplate are all blocked tightly with interference. The bottom of a pedestal cylinder is fixed at the pedestal. The inside of the blocking plate is provided with a plurality of blocking slots, which match with the shape of the guide rod. The elevating mechanism can ensure the function of elevating and at the same time can realize the function of rotary positioning, and the use performance of the elevating mechanism is improved, and the structure is simple, and the operation and use is flexible and convenient.
Description
Technical field
The present invention relates to a kind of elevating mechanism, relate in particular to a kind of lowering or hoisting gear of energy positioning corner.
Background technology
Existing rotatable elevating mechanism adopts Pneumatic power elevator apparatus usually.It as the patent No. 02250660.8 reinforced Pneumatic elevation bar, the occasion that this lowering or hoisting gear rotates to an angle at needs, can not on the position of required rotation, locate automatically, but it is fixing to need the user with additional force or device it to be blocked, uses extremely inconvenient.
Summary of the invention
Purpose of the present invention just provides a kind of lowering or hoisting gear of energy positioning corner, and this elevating mechanism can be realized the function of rotation location when guaranteeing elevating function, and the serviceability of raising elevating mechanism is simple in structure, manipulates flexible.
The present invention solves its technical problem, and the technical scheme that is adopted is:
A kind of lowering or hoisting gear of energy positioning corner, comprise handle, handle and connecting rod, base plate, starting bar, piston rod, urceolus, base, its design feature is: an end of the push rod on an end of handle and connecting rod and the base plate is fixedlyed connected, the other end of push rod has a U-lag, and push rod links to each other in U-lag in hinged way with an end of guide rod; Base plate is provided with free bearing, and guide rod passes base plate and is hinged on the free bearing simultaneously; The middle part of push rod is fixed with extension spring, and the other end of extension spring passes base plate, and links to each other with the end of the fixing guide groove of floor below; The end of guide groove also is connected with stage clip, and the other end of stage clip links to each other with the guide rod that passes guide groove; Urceolus is provided with chuck and chuck sleeve, chuck and chuck sleeve interference fit, and chuck sleeve meshes with the base tube again, and all interference is clamped on the urceolus; The bottom of base tube is fixed on the base; Have a plurality of in the chuck and the suitable draw-in groove of guide rod shape.
Operation principle of the present invention and process are: when elevating mechanism did not need to rotate, guide rod reset on the some draw-in grooves position in the chuck under the effect of stage clip elastic force, made about elevating mechanism to fix, and can not rotate; But under the effect of handle and connecting rod, the effect by starting bar, piston rod fully can oscilaltion, because push rod and the guide rod that links to each other with push rod link to each other with starting bar by extension spring, so can not influence the elevating function of elevating mechanism.When the user need rotate to an angle elevating mechanism, (or right) direction plate fixed handle left, the promotion push rod moves right, push rod drives guide rod and overcomes the elastic force of stage clip to left movement, withdraw from the draw-in groove on the chuck, and under the effect of the power of push rod, rotate around piston rod, and the base plate that drives elevating mechanism by free bearing rotates together, makes whole elevating mechanism rotation.When rotating to desired location, release handle, guide rod under the effect of stage clip elastic force, is returned in the draw-in groove of a certain correspondence on the chuck again, is positioned on this assigned address thereby base plate also is an elevating mechanism.
Compared with prior art, the invention has the beneficial effects as follows: by the effect of push rod, guide rod and chuck, elevating mechanism of the present invention can also can be realized spinning movement when realizing lifting, and the anglec of rotation can be controlled, and elevating mechanism can be positioned on the appointed positions; Simple in structure, easy for operation.
The present invention is further detailed explanation below in conjunction with accompanying drawing and concrete embodiment.

Fig. 2 is part (base plate) the sectional structure schematic diagram of the embodiment of the invention.
The specific embodiment
Embodiment
Fig. 1,2 illustrates, and a kind of specific embodiment of the present invention is:
A kind of lowering or hoisting gear of energy positioning corner, comprise handle 1, handle and connecting rod 1a, base plate 4, starting bar 10, piston rod 11, urceolus 12, base 13, one end of the push rod 2 on the end of handle and connecting rod 1a and the base plate is fixedlyed connected, the other end of push rod 2 has a U-lag, and push rod 2 links to each other in U-lag in hinged way with an end of guide rod 3; Base plate 4 is provided with free bearing 5, and guide rod 3 passes base plate 4 and is hinged on simultaneously on the free bearing 5; The middle part of push rod 2 is fixed with extension spring 6, and the other end of extension spring 6 passes base plate 4, and links to each other with the end of the guide groove 7 of base plate 4 belows; The end of guide groove 7 also is connected with stage clip 8, and the other end of stage clip 8 links to each other with the guide rod 3 that passes guide groove 7; Urceolus 12 is provided with chuck 14 and chuck sleeve 14a, and chuck 14 and chuck sleeve 14a interference fit, chuck sleeve 14a mesh with base tube 13a again, and all interference is clamped on the urceolus 12; The bottom of base tube 13a is fixed on the base 13; Have in the chuck 14 and have a plurality of and the suitable draw-in groove 14b of guide rod 3 shapes in the suitable draw-in groove 14b chuck 14 of a plurality of and guide rod 3 shapes.
The present invention is when implementing, and the number of the draw-in groove on the chuck can be decided according to the angle of the required rotation of reality location.
