Description
Technical field
The utility model relates to regulating mechanism, in particular to a kind of flexible lock adjustment mechanism.
Background technique
Existing height-adjustable desk or chair generally use the structure of foot tube design packaged tube, by desktop or
Person's seat fastens again when being raised to required height.But current lock mechanism is usually laborious when in use, locking
When it is laborious while when being adjusted loose, also usually there is the stuck appearance for being difficult to flexible situation, locking mechanism
Being difficult to the case where resetting usually occurs, the space that could be improved.
Utility model content
The purpose of the utility model is to provide a kind of flexible lock adjustment mechanisms, can easily be adjusted, locking and
Loose process is laborsaving and convenient.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of flexible lock adjustment mechanism slides the telescoping tube being sheathed in outer tube including outer tube, along outer tube length direction
And be installed on outer tube and stretch the sliding of telescoping tube into line-locked locking mechanism, the locking mechanism includes that fixation is arranged
In outer tube tail end positioning seat, be connected to the outer surface of positioning seat and extend through elastic press in telescoping tube, be installed on
Positioning seat and be connected to elastic press with into telescoping tube elasticity squeeze the locking member of the elastic press, along the length of telescoping tube
It is fixedly mounted to be matched with the locating piece that the elastic press is positioned；The locking mechanism further includes having along elastic press
It wears direction of extrusion elasticity and is connected to the reset for carrying out elastic reset between positioning seating face and elastic press to elastic press
Part.
Using the above scheme, realized by the positioning seat of locking mechanism and be fixedly connected with outer tube, elastic press with position
Block, which is matched with locking piece, can be realized occlusion locking, so that telescoping tube can mutually keep pine in elastic press and locating piece
Flexible sliding is carried out when the state of relaxation, and then can be realized fixed limit when the two is mutually twisted locking, by locking member side
Just the adjustment of realization foot tube length；And the return unit that elasticity abuts between elastic press and positioning seating face is to elastic press
Apply the elastic acting force of oriented remotely located piece of side movement tendency, so that when locking piece relaxation unlocks, bullet
Property briquetting under the effect of the elastic force of own resilient and return unit be smoothly detached from the occlusion of locating piece, avoid because of elastic press
Elastic force is too small and deformation failure causes locating piece and elastic press to be difficult to the drawbacks of being detached from and telescoping tube is caused to be difficult to telescopic adjustment,
It is more easily convenient when use.
Preferably, the elastic press is in T-shape, the positioning seat is equipped with the positioning for the elastic press inlay card

Position slot.
Using the above scheme, the locating slot that is opened up on positioning seat and in " T-type elastic press cooperates, locating slot
The perforation that center opens up elastic press partially to wear to carry out locking occlusion, and part is connected to the surface of locating slot
On limited, return unit is connected to locating slot and can smoothly be abutted with elastic press to carry out force reset.
Preferably, the surface bulge of the locating slot has the positioning column limited to return unit.
Using the above scheme, the positioning column of the surface bulge of locating slot can limit return unit, so that return unit
Installation stablize, stablize force direction, and the setting of positioning column also can effectively prevent elasticity
Briquetting causes deformation to be difficult to autonomous elastic recovery because squeezing.
Preferably, the positioning column is provided with several and symmetrically sets in the two sides of the perforation in the surface of locating slot
It sets.
Using the above scheme, positioning column is several in the setting of the surface of locating slot and is symmetrically arranged about perforation so that resetting
Part, for the force balanced, symmetrical of elastic press, avoids elastic press in locating slot because exerting a force not when being resetted
Skew inlay card caused by, when reset more smoothly and stabilization.
Preferably, the elastic press is provided with double wedge close to the side of locating piece, the surface edge of the locating piece is stretched
The length direction of the draw offers the tooth socket for being engaged in double wedge, and the tooth socket is arranged upward along the short transverse inclination of foot tube.
Using the above scheme, the double wedge on elastic press and the tooth socket on locating piece surface can be intermeshed inlay card, in turn
Realize mutual positioning, tooth socket is arranged upward along the short transverse inclination of pin, so that elastic press and locating piece are real
After existing inlay card, the case where telescoping tube is to outer tube contract appearance can be effectively avoided, and then be matched with locking member and to lock
Securely stablize when pin is supported use.
Preferably, the trailing exterior surface circumferential projection of the outer tube has several buckles for being fastened on the positioning seat；Institute
The card slot offered on telescoping tube for the locating piece inlay card is stated, the positioning seat is extended with inlay card in the flange in card slot.
Using the above scheme, the buckle of the trailing exterior surface circumferential projection of outer tube can carry out snapping to positioning seat and realize peace
Dress；The card slot opened up on telescoping tube can carry out inlay card limit to locating piece, and the flange inlay card that positioning seat extends makes in card slot
Obtain the cooperation for facilitating locating piece and elastic press when installation and adjusting.
Preferably, the tail end of the telescoping tube is fixedly installed with feet, the end surface of the feet is set in arc-shaped
It sets and is spaced apart and be equipped with several non-slip textures.
Using the above scheme, telescoping tube tail end be fixedly mounted feet can when pin is supported use into
Row abuts support, and the arc-shaped setting of end is matched with non-slip texture and makes when being supported according to adjusting height
Change so that feet there can be sufficient area stablize abutting with ground always.
Preferably, the locking member is eccentric cam spanner, the eccentric orfice and elastic press of the eccentric cam spanner
And the central axis of perforation is coplanar.
Preferably, the side of the eccentric cam spanner is protruding with tight locking button, the positioning seat circumferentially prolongs in locating slot
Stretching has boss, and the side of the boss offers the locking slot for being fastened on the tight locking button.
Using the above scheme, locking member uses eccentric cam spanner, enable when being moved smoothly into
Row locks and unlocks relaxation, and the tight locking button on locking member and the locking slot on the boss of positioning seat can cooperate, so that lock
Tight part can be fixed after being locked by stable, avoid easily being detached from.
In conclusion the utility model has the following beneficial effects:
By the cooperation of the locking member of locking mechanism, elastic press and locating piece, it is mutual with outer tube to can be realized telescoping tube
Between it is flexible, preliminary relaxation can be realized when locking member unlocks by the elasticity of elastic press itself and be detached from positioning
Block is realized quickly and smoothly and is detached from, and then the inlay card between elastic press and locating piece is avoided to make under the cooperation of return unit
At flexible difficulty, structure is simple, and effect is prominent.
