Description
Technical field
The utility model relates to a kind of drawing arrangement for adjusting height.
Background technology
At seat, on the daily household such as desk or specifically working equipment, setting height(from bottom) adjusting device can conveniently regulate and use, current modal arrangement for adjusting height is screw jacking mechanism and bolt connecting mechanism, the high still inconvenient operation of said mechanism security, need to take time dismounting, patent 2014200062840 " adjustable for height portable seat " provides a kind of arrangement for adjusting height utilizing latch and spring, comprise the inner and outer tubes be nested together and the spring be fixed together and latch, two inner and outer tubes are equipped with jack, latch is stuck in jack and inner and outer tubes is fixed, latch can be made to exit jack by Compress Spring, now inner and outer tubes can regulate height by Relative sliding, under the restoring force of spring, when interior pipe or outer sliding tube move on to certain position, latch card is stuck in jack again and inner and outer tubes is fixed, this device is easy to adjust, but there is following problem: when 1) fixing, latch is only stuck in the side of inner and outer tubes, inner and outer tubes discontinuity, affect service life, 2) spring is fixed on internal tube, inconvenient spring fitting.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of drawing arrangement for adjusting height, this apparatus structure is simple, easy for installation, uniform force.
The technical solution adopted in the utility model is:
A kind of drawing arrangement for adjusting height, comprise fixed bar, carriage release lever and link assembly, fixed bar is provided with hollow groove, and carriage release lever is located in the hollow groove of fixed bar, and fixed bar and carriage release lever are equipped with jack, described link assembly comprises latch, spring and button, the two ends of spring are connected with the outside of fixed bar and button respectively, and spring housing is on latch, and one end of latch is connected with button, under nature, latch is arranged in the jack of fixed bar both sides and the jack of carriage release lever.
As further improvement of the utility model, described spring is connected with fixed bar by sleeve, sleeve is located in the jack of fixed bar side, sleeve is provided with external screw thread, the jack that fixed bar is provided with sleeve side is screwed hole, sleeve and fixed bar are threaded connection, and one end and the sleeve of spring are fixed.
As further improvement of the utility model, be provided with sheet metal between described button inner face and latch end face, one end of spring is fixed on sheet metal, and button, sheet metal and latch are closely fixed by screw.
As further improvement of the utility model, the jack on described carriage release lever is provided with chamfering near one end of coupling assembling.
Compared to the prior art the utility model, has following outstanding beneficial effect:
1) in its natural state, because latch is arranged in the jack of fixed bar both sides and the jack of carriage release lever, fixed bar and carriage release lever can not Relative sliding, and now the stressed of fixed bar can be distributed to both sides, uniform force.
2) link assembly is located at outside fixed bar, facilitates spring fitting.
3) sleeve can be connected and fixed with the jack of differing heights on fixed bar, realizes two-way height and regulates, thus strengthen the adjustable range of height.

In figure: 1-carriage release lever; 2-fixed bar; 3-link assembly; 4-jack; 11-chamfering; 21-hollow groove; 31-sleeve; 32-latch; 33-spring; 34-sheet metal; 35-button; 36-screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As depicted in figs. 1 and 2, a kind of drawing arrangement for adjusting height, comprise fixed bar, carriage release lever and link assembly, fixed bar is provided with hollow groove, carriage release lever is located in the hollow groove of fixed bar and (can only moves up and down), fixed bar and carriage release lever are equipped with jack, described link assembly comprises latch, spring and button, the two ends of spring are connected with the outside of fixed bar and button respectively, spring housing is on latch, one end of latch is connected with button, under nature while fixing (namely fixed bar is relative with carriage release lever), latch is arranged in the jack of fixed bar both sides and the jack of carriage release lever.
In its natural state, because latch is arranged in the jack of fixed bar both sides and the jack of carriage release lever, fixed bar and carriage release lever can not Relative sliding, now the stressed of fixed bar can be distributed to both sides, uniform force, when needs regulate height, only need to pull out button, button drives latch outwards to move, when the on-fixed end of latch exits the jack on carriage release lever completely, carriage release lever can move up and down, when arriving required adjusting position, under the restoring force of spring, latch enters in the jack of fixed bar both sides and the jack of carriage release lever again.
As depicted in figs. 1 and 2, in the present embodiment, described spring is connected with fixed bar by sleeve, sleeve is located in the jack of fixed bar side, sleeve is provided with external screw thread, the jack that fixed bar is provided with sleeve side is screwed hole, and sleeve and fixed bar are threaded connection, and one end and the sleeve of spring are fixed.Sleeve can be connected and fixed by the jack of screw thread and differing heights, realizes two-way height and regulates, thus strengthen the adjustable range of height.
As shown in Figure 1 to Figure 3, be provided with sheet metal between described button inner face and latch end face, one end of spring is fixed on sheet metal, and button, sheet metal and latch are closely fixed by screw.Spring is fixed on sheet metal, and sheet metal is fixed on button, and this fixed form solves spring and is not easily fixed on problem on button, button, sheet metal can be fixed together with latch simultaneously, and structure is simple, easy to operate.
As depicted in figs. 1 and 2, the jack on described carriage release lever is provided with chamfering near one end of coupling assembling.Carriage release lever arranges chamfering and is convenient to coordinate with latch.
Should be understood that, above-mentioned specific embodiment only in order to explain the utility model, and is not used in restriction the utility model.
