Description

A kind of expansion and cotraction regulator

Technical field

The utility model is related to mechanical-stretchings to adjust field, more specifically more particularly to a kind of expansion and cotraction regulator.

Background technology

In the prior art, telescopic device be typically be fixed by screw, buckle, the fastening means such as bolt implement locking, When with above method, the relative position of fastening object has just been fixed, if the fixed position of fastening object is inappropriate It needs to reopen clamp device and re-starts fixation behind the position of adjustment fastening object, such mode of operation compares It is time-consuming and relatively elaborate.For example, in the adjusting height devices of common teaching desk and chair, connected usually using bolt Upper and lower two columns, all many holes on the column of such design extract bolt when needing to adjust height, mobile good position At the hole for postponing alignment lower upright, it is inserted into bolt.These pin members usually pass through the gravity pressure between lower upright Firmly bolt carrys out vertical columns, plays adjustment effect.

It can be seen that these modes are very time-consuming, laborious and efficiency is low, complicated defect；For this defect, Also occurs a kind of device using hydraulic regulation height in the market, but device is because of the defects of its is of high cost, complicated hardly possible To be esthetically acceptable to the consumers.So it is this field skill to provide a kind of extension adjustment device that convenience is flexible, simple in structure, safe and reliable The technical issues that need to address of art personnel.

Utility model content

The utility model provides a kind of structure letter for the difficult point that existing telescopic device is complicated, scaling operation is cumbersome Singly, convenient for the expansion and cotraction regulator of scaling operation.

The utility model using following technical scheme in order to solve the above technical problems, realized：

A kind of expansion and cotraction regulator is designed, the expansion and cotraction regulator includes the first column, guide rail, the second column, adjuster；Institute It includes button nail, locking plate, torsional spring, torsional spring bolt, lock body, locking plate pressure tongue to state adjuster；The button nail is fixed in the upper of locking plate End, locking plate are superimposed upon on lock body, and torsional spring is superimposed upon on locking plate, and torsional spring bolt is each passed through lockhole and torsional spring；The adjuster Lock body is bolted with the second column by first；The guide rail is plugged between lock body and torsional spring, torsional spring bolt, on guide rail End is equipped with several pressure tongue apertures that upper next column arranges；First column, guide rail are fixed together by the 4th bolt.

In use, it is fixed in the first pillar, press the button nail of adjuster so that locking plate upper end direction guiding rail side To close, under the effect of regulations and parameters principle, locking plate pressure tongue in locking plate lower end is detached from guide rail pressure tongue apertures and only needs to pull in that case Second pillar can easily make the first pillar and the second pillar make opposite sliding to achieve the purpose that adjust height；When adjusting is arrived When appropriate height, release button nail so that locking plate resets, and locking plate pressure tongue is held in pressure tongue apertures, you can so that the second pillar is solid It is scheduled on the first pillar corresponding height, without declining.Utilize principles above, you can conveniently and efficiently adjust telescopic adjustment height.

Preferably, described first bolt or so is respectively provided with two.Reinforce the fastening effect between adjuster and the second column.

Preferably, the pressure tongue apertures is equipped with seven altogether.It can easily realize the adjusting of length.

Preferably, it is attached by elastic component between the guide rail and adjuster；Elastic component is bolted by second In the lock body lower end of adjuster, the other end is bolted to guide rail lower end by third.By elastic component by guide rail and adjuster It links together, when being followed closely by lower button, the effect of power is lost between locking plate pressure tongue and pressure tongue apertures, using returning for elastic component Elastic energy, the first pillar and the second pillar rapid desufflation, have the function that shorten adjustable range automatically.

Preferably, the elastic component is tension spring.

With the above structure, advantageous effect is the utility model：The utility model is simple using simple structure, can It leans on, it may be convenient to carry out telescopic adjustment operation up and down.

Description of the drawings

The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute to this reality With novel any restrictions.

Fig. 1 is the structure schematic elevation view of the utility model；

Fig. 2 is the structure left view schematic diagram of the utility model；

Fig. 3 is the utility model decomposition texture schematic diagram.

In figure：First column 1, the second column 3, adjuster 4, lockhole 5, elastic component 6, button nail 7, locking plate 8, is turned round guide rail 2 Spring 9, torsional spring bolt 10, lock body 11, locking plate pressure tongue 12, the first bolt 13, pressure tongue apertures 14, the second bolt 15, third bolt 16, the Four bolts 17.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Refering to fig. 1 shown in -3, a kind of expansion and cotraction regulator of the utility model, including the first column 1, guide rail 2, the second column 3, adjuster 4；Adjuster 4 includes button nail 7, locking plate 8, torsional spring 9, torsional spring bolt 10, lock body 11, locking plate pressure tongue 12；Button nail 7 It is fixed in the upper end of locking plate 8, locking plate 8 is superimposed upon on lock body 11, and torsional spring 9 is superimposed upon on locking plate 8, and torsional spring bolt 10 is each passed through lock Hole 5 and torsional spring 9.
