Abstract

The utility model relates to a liftable and rotatable adjusting device. The adjusting device comprises a rest stand base (1). A feed screw nut (2) is arranged in the sampling tube rest stand base (1). The rest stand base (1) is fixedly connected with the feed screw nut (2). A screw rod (3) which is in screw-thread fit with the feed screw rod (2) is arranged in the feed screw rod (2). A surface bearing (9) is arranged on the upper portion of the screw rod (3) and is limited through an external circlip (10) on the surface bearing (9). The surface bearing (9) is arranged in a bearing base (12). A screw rod bearing cover (7) and the bearing base (12) are connected through a sunk screw (8). The bearing base (12) is connected with a rest carrier (11) which can rotate freely. The adjusting device is used for adjusting the height, the position and the direction of a pipe, simple in structure, high in practicality and suitable for market promotion.

Description

The rotatable controlling device of a kind of lifting

Technical field

The utility model 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.

Model utility content

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

The technological scheme that realizes the employing of the utility model object is:

The rotatable controlling device of lifting, for regulating height and position and the orientation of pipe fitting, is characterized in that: this controlling device comprises that is shelved a stand, and sample pipe is shelved in stand a feed screw nut, shelves stand and is fixedly connected with feed screw nut; In feed screw nut, be provided with a screw mandrel for screw-thread fit with it; One plane bearing is arranged at screw mandrel top, by circlip for shaft, 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 bracket, shelves bracket 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 handlebar two ends.

Preferentially, described in shelve stand and be trigonometric form, which is provided with a screw shell, described bracket can move up and down.

Preferentially, described in shelve bracket and be placed on above bearing, by bearing, the rotatable adjusting of bracket orientation.

The beneficial effects of the utility model are: by the rotation between screw mandrel and screw shell, carry out the lifting of object in bracket, come the orientation of object place horizontal plane in bracket by the rotation of the plane bearing on screw mandrel.

The utility model low cost, has 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.

Embodiment

By a kind of specific embodiment of the present utility model, the utility model is further expalined and is illustrated below, 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], sample pipe is shelved in stand [1] a feed screw nut [2], shelves stand [1] and is fixedly connected with feed screw nut [2]; In feed screw nut [2], be provided with a screw mandrel for screw-thread fit [3] with it; Described screw mandrel [3] upper end is provided with a handlebar [5], one plane bearing [9] is arranged at screw mandrel [3] top, plane bearing [9] is spacing by it by circlip for shaft [10] above, 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 bracket [11], and shelving bracket [11] can rotate freely.

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

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