Abstract
A split lift-and-pull erector is provided, which belongs to the office furniture field, and comprises an erector base, an external iron casing pipe erected on the base and an internal iron casing pipe inside it, and is characterized in that: the internal iron casing pipe is inserted with an axial linkage shaft rod, which has a pull handle connected with the internal iron casing pipe at the top end, and the lower end is provided with a limiting hole and a limiting pin sliding along the hole, the limiting pin is provided with a flat cross screw; a spring is connected between the linkage shaft rod and the internal iron pipe; the inner wall of the external iron casing pipe is welded with a vertical pinion rack; a positioning spacer is arranged and connected between the internal and external iron casing pipes. By adopting the split structure, the lift-and-pull type erector drives the lift up and down of desk legs depend on the moving upward and downward of the linkage rod, and is easy to operate, durable, and is suitable for 5 years children and above and adults, being very economic.
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 split crane of desktop or table surface height.
Background technology
In the adjustment action for the desk height, lifting is to realize by stretching of table pin length.Have only the desk of child below 10 years old that height-adjustable function is arranged at present, and be to realize by more original mode.Original mode is they to be fixed up with nut by two joints monolithic hollow or steel plate with holes, refill after must will nut taking out when realizing the desktop lifting, operate loaded down with trivial details, again since a table pin be last wide down carefully, entire table is waved also built on the sand easily after tightening up nut.The not single child of this regulative mode independent operation of having no way, adult's gas of also requiring great effort very much that operates, the life-span of this type of desk is very short in addition, how could become child's study desk and to regulate height and durable in use easily? for solving this class problem, thereby the hope and the demand of further reform have been produced.
Summary of the invention
The utility model technical issues that need to address are, relatively require great effort and child can't independently operate at existing up-down mode, and there is inconvenience in this version, in order to overcome these defectives, will redesign a kind of version.The purpose of this utility model provides a kind of pull-type crane, and this is a kind of split-type structural mechanical elevating frame, and it adopts the rising or the reduction that drives the desk foot rest that move up and down of trace.
The purpose of this utility model realizes by the following technical solutions, a kind of pull-type 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, be inserted with interlock axostylus axostyle assembly in the interior ferule vertically, this interlock axostylus axostyle upper end is provided with a pull handle that links to each other with interior ferule, the spacer pin that interior ferule lower end is provided with spacing hole and slides along the hole, and this spacer pin is provided with the tack Philip's head screw; Be connected with a spring between described interlock axostylus axostyle and the described interior ferule; Be welded with a vertical stationary rack on the described outer ferule inwall; Be connected between the inside and outside ferule and locate, be provided with positioning spacer.Described interlock axostylus axostyle also moves up and down under the moving up and down of pull handle thereupon, slides along spacing hole thereby drive spacer pin, under the telescopic action of spring, realize that spacer pin tightens on stationary rack, and the connecting axle by being attached thereto, the lifting of ferule in promoting.
The beneficial effects of the utility model are that this pull-type crane because the employing split-type structural relies on trace to move up and down, drives the lifting of desk pin, makes easy to operate, durable in use, suitable children and adult's use, economical and practical more than five years old.
Description of drawings
Fig. 1 is a pull-type split crane structure connection diagram.
The specific embodiment
With reference to Fig. 1, expression pull-type split crane structure, the crane base is 1 among the figure, it is supporting interlock axostylus axostyle assembly 3, be crane upper table surface 2 topmost, what be positioned at couple axle bar assembly periphery under the table top is ferule 4, and it is outer to be outer ferule 6, the parts that connect internal and external casing are positioning spacer 5, and outer ferule inside is welded with vertical stationary rack 7.In the described interlock axostylus axostyle assembly 3, also include the spacing hole 3.1 that is positioned at the ferule bottom, with interlock axostylus axostyle and the fixing spring 3.2 of interior ferule, spacer pin 3.3 also is provided with flat head screw 3.4 on this spacer pin, and axostylus axostyle top is provided with and lifts handle 3.5.Positioning spacer between the inside and outside ferule adopts the plastic cement spacer.
Claims (2)
1. pull-type 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, be inserted with interlock axostylus axostyle assembly in the interior ferule vertically, this interlock axostylus axostyle upper end be provided with one with the pull handle that links to each other, the spacer pin that interior ferule lower end is provided with spacing hole and slides along the hole, this spacer pin is provided with the tack Philip's head screw; Be connected with a spring between described interlock axostylus axostyle and the described interior ferule; Be welded with a vertical stationary rack on the described outer ferule inwall; Be connected between the inside and outside ferule and locate, be provided with positioning spacer.
