Abstract
A leg pipe height adjusting device comprises a leg pipe, a telescopic pipe, a blocking sleeve, a foot pad knob, a foot pad disk and an adjusting mechanism. The adjusting mechanism comprises a slotted nut, a lining, a nut, a compressed spring, a connecting sleeve and a bolt. The height adjustment is to tighten and loosen the slotted nut by the bolt, and the telescopic pipe is adjusted by tightening and loosening the slotted nut and the leg pipe. Meanwhile, for the action of the compressed spring, the utility model is provided with buffer action. The utility model can be used in chairs, beds, stools and the other components, by which the height or length adjustment is needed.
Description
Technical field
The utility model relates to the adjustable for height device of a kind of pin pipe, particularly a kind of adjusting device with cushioning effect.
Background technology
Existing pin pipe height is regulated, with the chair is example, and its governor motion generally adopts card 11, card bed 12, stage clip 13, sees Fig. 1, during use, card 11 is pressed, spurred telescoping tube 14 then, when being adjusted to desired height, loosen card 11, under the effect of stage clip, card 11 upwards blocks telescoping tube 14 and finishes adjusting.The advantage of this governor motion is simple in structure, and is easy to adjust.Its shortcoming is: 1, owing to use card to block the telescoping tube surface, therefore after repeatedly using, stay many scars on the telescoping tube surface, influence outward appearance; 2, between telescoping tube and pin pipe, and all gapped between they and the card bed, therefore have noise in use and produce, and be sitting in loosening sense is arranged on the chair.
Summary of the invention
The utility model solves mainly that the pin pipe easily abrades in the prior art, influences attractive in appearance and comfortableness.
The utility model is to solve by following technical scheme.
The utility model is made up of pin pipe 1, telescoping tube 2, interstage sleeve 3, foot pad knob 4, foot pad dish 5 and governor motion 6, it is characterized in that governor motion 6 is made of slotted nut 61, bolt 62, stage clip 63, adapter sleeve 64, lining 65 and nut 66, its assembly relation is a dress adapter sleeve 64 on telescoping tube 2, put stage clip 63 on the adapter sleeve 64, on stage clip 63, put lining 65, bolt 62 is penetrated adapter sleeve 64, stage clip 63, lining 65 backs to be tightened with nut 66, be screwed into slotted nut 61 then, be inserted in pin pipe 1 to shelves at last and overlap till 3.During use, with 4 counter-rotatings of foot pad knob, bolt 62 and fluting spiral shell 61 are unscrewed, and slotted nut 61 and pin pipe 1 unclamp, and can spur telescoping tube 2 to desired height, then that foot pad knob 4 is clockwise, bolt 62 is tightened slotted nut 61, and slotted nut 61 struts, thereby makes the inwall frictional force of slotted nut 61 and pin pipe 1 increase to pre-provisioning request, just can bear external weight, therefrom locking.Because be with stage clip 63 in the bolt 62, as seen from Figure 2, pin pipe 1 is under the effect of external force, stage clip 63 has played cushioning effect.
Advantage of the present utility model: 1, easy to adjust, to unscrew and tighten the foot pad knob, the pulling telescoping tube can be regulated height; 2, owing in the pin pipe stage clip is housed, can plays cushioning effect when being stressed, as being contained on the chair, four legs of chair can be adjusted to comfortable position, particularly ground not at ordinary times automatically, and are particularly suitable; 3, because whole governor motion all in pipe, makes whole pin pipe more attractive in appearance.
The utility model can be used on the member that the chair, bed, stool of metal control and height or length need stretch.
Description of drawings
Fig. 1 is the schematic diagram that prior art pin pipe height is regulated;
Fig. 2 is a structure chart of the present utility model;
Fig. 3 is the structure chart of slotted nut 61 of the present utility model;
Fig. 4 is a simple type structure chart of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, technology of the present utility model is described further.
Embodiment 1: the utility model as shown in Figure 2, pin pipe 1 and telescoping tube 2 can be made of pipe or square tube, use pipe in the present embodiment, pin pipe 1 usefulness aluminium alloy φ 19 * 1.2, telescoping tube aluminium alloy φ 16 * 1.2, slotted nut 61, lining 65, adapter sleeve 64, interstage sleeve 3, foot pad knob 4, foot pad dish are all used the engineering plastics injection mo(u)lding, and bolt 62, nut 66 and stage clip 63 are made of a steel.The periphery of slotted nut 61 has flank, sees Fig. 3, and it and pin pipe 1 inwall have initial frictional, makes bolt 62 when beginning to twist, and slotted nut 61 can and then not change, and can tighten.
Embodiment 2: in embodiment 1 as nut 66, lining 65, stage clip 63 are saved, change the through hole of adapter sleeve 64 into blind hole and bolt 62 is injection molded into one, as shown in Figure 4, then the utility model becomes the simple type with cushioning effect, cost can reduce, and can select according to purposes.
Claims (3)
