Abstract
A pulling type crane with screens being separated belongs to the field of office furniture, including a crane chassis, an external ferule erected on the chassis, and a internal ferule positioned in the inner side of the chassis; equidistant round holes are arranged along the wall surface of the internal ferule; a hollow short round tube is arranged at the upper end of the external ferule which is internally provided with a screens pulling plug module the center of which is provided with a screens shaft contacted with the internal ferule; the terminal part of the screens shaft is provided with a screw thread and sleeved with a spring; the outside of the screens pulling plug module is provided with a puling plug knob the inner side of which is provided with a screw thread which is connected to the screens shaft through a meshed locknut; a plastic positioning gasket is arranged at the connection between the internal ferule and the external ferule. The pulling type crane lifts and descends the desk feet by loosening and tightening the screens pulling plug and the horizontal motion of the screens pulling plug. The pulling type crane has convenient operation, durable usage and stronger function and elegant appearance.
Description
Technical field
The utility model belongs to field of office furniture, specially refers to when being used for table for computer and workbench, regulates the pull-type screens split crane of desktop or table surface height.
Background technology
The adjustment of desk, computer desktop height, lifting are to realize by stretching of table leg length.Present same table much adopts Pneumatic elevation to regulate height, and this up-down mode when table top is elevated to certain altitude, can produce instability, and certain danger is arranged.Some desk or table for computer are by more original mode, they are fixed up with nut by two joints monolithic hollow or steel plate with holes, realize the support to desktop.Realize the desktop lifting, refill after must will nut taking out that operate loaded down with trivial detailsly, entire table is waved easily behind the hold-down nut.This regulative mode, children's independent operation of having no way not only, adult's very effort that operates also.In addition, the life-span of this type of desk is very short, how could become the desk that children learn usefulness and regulate height and durable in use easily? for solving this class problem, produced the demand of further reform.
Summary of the invention
The utility model technical issues that need to address are, at existing up-down mode relatively require great effort, children can't independently operate and crane waits defective built on the sand, in order to overcome these many deficiencies, will redesign a kind of version.The purpose of this utility model provides a kind of pull-type screens split crane, and this is a kind of split-type structural mechanical elevating frame that utilizes screens, and it adopts and twists, spurs rising or the reduction that the screens pulling plug is realized the lifting foot rest.
The purpose of this utility model realizes by the following technical solutions, a kind of pull-type screens split crane, comprise the crane base, be erected at the outer ferule on the base and be positioned at the ferule of its inboard, it is characterized in that, along on the interior ferule wall, be provided with equidistant circular hole, empty short pipe in outer ferule upper end is provided with, be provided with screens pulling plug assembly in it, this screens pulling plug assembly center is provided with one and the contacted screens axle of interior iron pipe, and the screens shaft end is provided with rib-loop and is with spring, and the screens pulling plug assembly outside is provided with the pulling plug handle, this pulling plug handle inboard is provided with screw thread, and this screw thread links to each other with the screens axle by the nut that tightens up of interlock; Inside and outside ferule junction is provided with the plastic cement positioning spacer.Described screens axle, its axostylus axostyle adopts a circular section or an end circular section, and the other end is an oval cross section.Ferule also easily moves up and down under the degree of tightness of pressure and screens axle up or down thereupon in described, thereby realizes the lifting of crane.The degree of tightness of described screens axle is to realize by the spring of screens pulling plug the inside.
The beneficial effects of the utility model are, this pull-type screens crane, owing to adopt split-type structural, rely on degree of tightness screens pulling plug, the light oscilaltion of ferule in making, rotation pulling plug handle can be realized mobile, easy to operate, durable in use, suitable children and adult's use, with better function, elegant in appearance more than five years old of ferule in the crane.
Description of drawings
Fig. 1 is a pull-type split crane structure connection diagram;
Fig. 2 is screens pulling plug assembly and inside and outside ferrous pipe structure connection diagram;
Fig. 3 draws for screens and fastens the assembly decomposing schematic representation.
The specific embodiment
With reference to Fig. 1, expression pull-type split crane structure, the crane base is 8 among the figure, and it is supporting outer ferule 2, and the most inboard is interior ferule 1, and the parts that connect internal and external casing are positioning spacer 9, empty short pipe 10 in outer ferule outside is welded with.In the described screens pulling plug assembly 3, also include the pulling plug handle 4 that is positioned at screens pulling plug top, with pulling plug the palmistry interlock tighten up nut 5, with the pulling plug handle with tighten up the screens axle 7 that nut is together in series, and the spring 6 that is enclosed within screens axle one end.Positioning spacer between the inside and outside ferule adopts the plastic cement spacer.During the same table frame, only need turn 4 liang of circles of pulling plug handle, make it loosening, then toward horizontal direction pulling pulling plug handle, under the effect of spring 6, locating shaft 7 leaves interior iron pipe circular hole, at this moment only need up or in press down ferule 1, be raised to predetermined altitude, decontrol pulling plug handle 4, the screens axle promptly inserts interior ferule circular hole, has promptly realized the lifting of crane.
Claims (3)
1. pull-type screens split crane, comprise the crane base, be erected at the outer ferule on the base and be positioned at the ferule of its inboard, it is characterized in that, along on the interior ferule wall, be provided with equidistant circular hole, empty short pipe in outer ferule upper end is provided with, be provided with screens pulling plug assembly in it, this screens pulling plug assembly center is provided with one and the contacted screens axle of interior iron pipe, the screens shaft end is provided with rib-loop and is with spring, the screens pulling plug assembly outside is provided with the pulling plug handle, and this pulling plug handle inboard is provided with screw thread, and this screw thread links to each other with the screens axle by the nut that tightens up of interlock; Inside and outside ferule junction is provided with the plastic cement positioning spacer.
