Abstract

The invention relates to the technical field of machines, in particular to a height adjuster. The height adjuster comprises a body, a lengthened rack, a driving base, a swivel limiter, a swivel, a swivel clamping groove, a rotating space, a connecting rod, a driving gear and a spring. The lengthened rack is located inside the body; the driving base is located on the outer side of the body; the swivel limiter is located on the outer side of the swivel 4; the swivel limiter is located in the swivel clamping groove; the rotating space is located inside the driving base; the rotating space is located between the swivel and the body; the connecting rod is located between the swivel and the driving gear; the driving gear is located inside the body; the driving gear is engaged with the lengthened rack; the connecting rod is sleeved with the spring; the spring is located between the body and the swivel. The height adjuster is simple in structure and convenient to use, and can carry out height adjustment only by a person with a screwdriver; after adjustment is completed, the spring can automatically pop out the swivel outwards, the swivel limiter is embedded into the swivel clamping groove, rotation of the driving gear is effectively avoided, the height of the height adjuster is prevented from changing, and high stability is achieved.

Description

A kind of height adjuster

Technical field

The present invention relates to field of mechanical technique is and in particular to a kind of height adjuster.

Background technology

In daily life, the article height being frequently encountered use needs to be adjusted, but enters in article Line height all uses self-contained scalable device when adjusting, and always some objects itself need without height adjusting function again Altitude mixture control to be carried out, is run into this situation and typically using external force, whole article is sling, and lowly fills in certain padded Article, also need to loaded down with trivial details manpower and materials and sling again object when needing Secondary Control.

Content of the invention

Present invention aims to the defect of prior art and deficiency, provide a kind of structure simple, reasonable in design, make With a kind of easily height adjuster, it includes body, extends tooth bar, drive seat, swivel stop, swivel, swivel draw-in groove, rotation Turn space, connecting rod, driving gear, spring；Extend tooth bar and be located within the body portion；Drive seat is located at outer body；Rotation Ii miter It is located at outside swivel 4；Swivel stop is located in swivel draw-in groove；Revolution space is located inside drive seat；Revolution space is located at and turns Between body and body；Connecting rod is located between swivel and driving gear；Driving gear is located within the body portion；Driving gear and prolongation tooth It is engaged between bar；Spring housing is on connecting rod；Spring is located between body and swivel.

After said structure, the present invention has the beneficial effect that：A kind of height adjuster of the present invention, its structure letter Single, easy to use it is only necessary to a people be may be height adjusted using a screwdriver；After regulation terminates, spring can be by Swivel outwards ejects automatically, so that swivel stop is embedded in swivel draw-in groove, is effectively prevented the rotation of driving gear, prevents Height adjuster highly changes, and stability is strong.

Brief description

Accompanying drawing described herein is used to provide a further understanding of the present invention, constitutes the part of the application, but Do not constitute inappropriate limitation of the present invention, in the accompanying drawings：

Fig. 1 is present configuration schematic diagram；

Fig. 2 is the sectional view of A-A part in Fig. 1.

Description of reference numerals：

1- body, 2- extend tooth bar, 3- drive seat, 4- swivel stop, 5- swivel, 6- swivel draw-in groove, 7- revolution space, 8- even Bar, 9- driving gear, 10- spring, 2-1 straight-tooth, 5-1 cross rotation slot.

Specific embodiment

To describe the present invention below in conjunction with accompanying drawing and specific embodiment in detail, illustrative examples therein and saying Bright be only used for explaining the present invention, but not as a limitation of the invention.

As illustrated, a kind of height adjuster described in this specific embodiment, it includes body 1, extends tooth bar 2, drives Dynamic seat 3, swivel stop 4, swivel 5, swivel draw-in groove 6, revolution space 7, connecting rod 8, driving gear 9, spring 10；Extend tooth bar 2 Inside body 1；Drive seat 3 is located at outside body 1；Rotation Ii miter 4 is located at outside swivel 5；Swivel stop 4 is located at and turns In body draw-in groove 6；Revolution space 7 is located inside drive seat 3；Revolution space 7 is located between swivel 5 and body 1；Connecting rod 8 is located at and turns Between body 5 and driving gear 9；Driving gear 9 is located inside body 1；It is engaged between driving gear 9 and prolongation tooth bar 2；Spring 10 It is enclosed within connecting rod 8；Spring 10 is located between body 1 and swivel 5.

Further：The described surface extending tooth bar 2 is provided with straight-tooth 2-1.

Further：The outside side of described swivel is provided with cross rotation slot 5-1.

A kind of height adjuster of the present invention, it only needs to adjust actuator as needs height when in use Below the object of section, the form of two ends welding may also be employed；When carrying out altitude mixture control, it is placed in cross rotation slot 5- with screwdriver At 1, while pushing, swivel 5 internally moves in revolution space 7, and swivel stop 4 is transported inside swivel draw-in groove 6 simultaneously Dynamic, it is separated from the restriction of swivel draw-in groove 6, driving gear 9 extends tooth bar 2 transverse movement in the transmission dynamics lower edge of connecting rod 8；Then Rotated at cross rotation slot 5-1 with screwdriver, under being transmitted by the dynamics turning 5 and connecting rod 8, driving gear 9 follows rotation, Thus driving prolongation tooth bar 2 to move up and down；After altitude mixture control puts in place, while Unscrewed screw knife, spring 10 self-resetting, 5 will be turned outwards elapse, and so that swivel stop 4 is come back to inside swivel draw-in groove 6, carry out spacing and Stabilization.

A kind of height adjuster of the present invention, its structure is simple, easy to use it is only necessary to a people adopts a spiral shell Silk knife may be height adjusted；After regulation terminates, swivel can outwards be ejected by spring automatically, so that swivel stop is embedded in In swivel draw-in groove, it is effectively prevented the rotation of driving gear, prevents height adjuster from highly changing, stability is strong.

The above is only the better embodiment of the present invention, therefore the construction described in all scopes according to present patent application, Equivalence changes or modification that feature and principle are done, are all included in the range of present patent application.
