Abstract

The invention relates to a liftable rotatable adjusting device. The liftable rotatable adjusting device comprises a containing shelf base (1), a lead screw nut (2) is arranged in the sampling tube containing shelf base (1), and the containing shelf base (1) is fixedly connected with the lead screw nut (2). A lead screw (3) which is in thread fit with the lead screw nut is arranged in the lead screw nut (2), a plane bearing (9) is arranged on the upper portion of the lead screw (3), an elastic retaining ring for a shaft (10) is used for limiting the upper portion of the plane bearing (9) which is arranged in a bearing base (12), and a lead screw bearing cover (7) is connected with the bearing base (12) through a sunk screw (8). The bearing base (12) is connected with a containing shelf bracket (11) which can be freely rotated. The liftable rotatable adjusting device is used for adjusting the height, the position and the direction of a pipe fitting, and is simple in structure, high in practicability and suitable for being popularized on the market.

Description

The rotatable controlling device of a kind of lifting

Technical field

The present invention relates to a kind of lifting rotation controlling device.

Background technique

Existing elevation and subsidence regulating device is a lot, but most structure is more complicated, and price is more expensive, and can only carry out up-down adjustment.For some, there are the pipe fitting of specific (special) requirements or the object of orientation requirement not to be suitable for, so wish the controlling device that a kind of cost is lower and a plurality of devices of energy are used in conjunction with.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structurely, cost is relatively low, and is applicable to the rotary regulator of the lifting of large-size pipe.

Realize that the technological scheme that the object of the invention adopts is:

The rotatable controlling device of a kind of lifting, height and position and orientation for regulating pipe fitting is characterized in that: this controlling device comprises that is shelved a stand, and the sample pipe is shelved in stand a feed screw nut, shelves stand and is fixedly connected with the feed screw nut; Be provided with a screw mandrel of screw-thread fit with it in the feed screw nut; One plane bearing is arranged at screw mandrel top, by circlip for shaft, that it is spacing above plane bearing, and plane bearing is placed in bearing support, by sunk screw, connects screw mandrel bearing cap and bearing support; Bearing support is linked with shelves carriage, shelves carriage and can rotate freely adjusting pipe fitting direction.

Preferentially, the upper end of described screw mandrel is provided with a handlebar, and there is respectively a handle ball at the handlebar two ends.

Preferentially, the described stand of shelving is trigonometric form, which is provided with a screw shell, and described carriage can move up and down.

Preferentially, the described carriage of shelving is placed on above bearing, by bearing, and the rotatable adjusting of carriage orientation.

The invention has the beneficial effects as follows: carry out the lifting of object on bracket by the rotation between screw mandrel and screw shell, come the orientation of object place horizontal plane on bracket by the rotation of the plane bearing on screw mandrel.

Low cost of the present invention, realized by mechanical realization the controlling device that a kind of cost is lower and a plurality of devices of energy are used in conjunction with, and is applicable to promoting the use of.

Fig. 1 is basic profile of the present invention and structural representation;

Fig. 2 is broken section of the present invention and structural representation;

Fig. 3 is sample pipe kitchen knife rest schematic diagram of the present invention.

In accompanying drawing: 1, shelve stand 2, feed screw nut 3, screw mandrel 4, Cock screw 5, handlebar 6, handle ball 7, screw mandrel bearing cap 8, sunk screw 9, plane bearing 10, circlip for shaft 11, shelve carriage 12, bearing support 13, shelf supporting leg 14, shelf standpipe

Embodiment

Below by a kind of specific embodiment of the present invention, the present invention is further expalined and illustrates, as shown in accompanying drawing 1 and accompanying drawing 2, the rotatable controlling device of a kind of lifting, for regulating height and position and the orientation of pipe fitting, what this controlling device comprised three legs shelves stand [1], the sample pipe is shelved in stand [1] a feed screw nut [2], shelves stand [1] and is fixedly connected with feed screw nut [2]; Be provided with a screw mandrel of screw-thread fit [3] with it in feed screw nut [2]; Described screw mandrel [3] upper end is provided with a handlebar [5], one plane bearing [9] is arranged at screw mandrel [3] top, by circlip for shaft [10], that it is spacing above plane bearing [9], plane bearing [9] is placed in bearing support [12], by sunk screw [8], connects screw mandrel bearing cap [7] and bearing support [12]; Bearing support [12] is linked with shelves carriage [11], and shelving carriage [11] can rotate freely.

By above structure, the present invention has realized having the pipe fitting of specific (special) requirements or the adjusting of the object that orientation requires to use for some, and cost is lower.

But above specific embodiment is only a kind of better embodiment of the present invention, not content of the present invention is whole, and the equivalents that Dan Fan does in protection domain of the present invention is all in protection domain of the present invention.
