Strip hole extends along the length direction of lower pillar stand 2 on the deck 5, and one is additionally provided with deck 5 with the position of bar hole 10
Corresponding arc-shaped hole 12, second fastener is the bulge-structure 13 on the wall of side on fastener 4, and the bulge-structure 13 be able to be along the circle
Arcuate socket 12 is slided, on deck 5 first fastener be arc-shaped hole 12 dorsad the side end of tooth bar 3 formed grown along lower pillar stand 2
The turning structure 14 that degree direction extends, the rotating shaft 11 of the fastener 4 strip hole movement along deck 5 be able to make raised knot on fastener 4
Structure 13 is slided into the turning structure 14 of the end of arc-shaped hole 12 of deck 5, when the bulge-structure 13 on fastener 4 slips into circular arc
After in the turning structure 14 of the end of hole 12, the bulge-structure 13 on fastener 4 is subject to the longitudinal side wall backstop of turning structure 14, fastener 4
Cannot now rotate again, it is to avoid stuck point 7 is contacted with the teeth groove 8 of tooth bar 3 thereon, it is to avoid fastener 4 is engaged with tooth bar 3, now
Can ensure that upper pillar stand 1 is not limited slidably by fastener 4.
The turning structure 14 of the end of arc-shaped hole 12 is square up or down along the length direction of lower pillar stand 2 on the deck 5
Extend.
An elastic component is additionally provided with, the elastic component can keep fastener 4 to become with the motion rotated towards the direction of tooth bar 3 all the time
Gesture, it is ensured that upper and lower column 2 is not acted on down the engagement for remaining fixed by external force, it is to avoid forgotten after the completion of regulation
Going back to card causes upper pillar stand 1 to be glided automatically under Gravitative Loads.
The elastic component is the torsion spring 15 being sheathed in the rotating shaft 11 of fastener 4, the two ends of torsion spring high 15 respectively with fastener 4 and deck
5 are fixedly connected, the simple structure, are easy to implement, and can also be realized using extension spring or stage clip in addition.
On the basis of actually used direction, the upper side wall of teeth groove 8 of the tooth bar 3 is horizontal plane, and lower wall is inclined plane, tooth
The opening of groove 8 is additionally provided with one with the opening direction identical V of teeth groove 8 gradually to increase each top of teeth groove 8 in structure, and tooth bar 3
Shape open slot 16, is additionally provided with a salient point 6 on fastener 4, on the fastener 4 stuck point 7 and salient point 6 respectively with teeth groove 8 and V on tooth bar 3
The size and shape of shape open slot 16 is matched, and stuck point 7 on fastener 4 is able to corresponding inserted in the tooth on tooth bar 3 with salient point 6
In groove 8 and V shaped opening groove 16, after salient point 6 and V shaped opening groove 16 are pinned, the upward stress of tooth bar 3 is not allowed to be twitched, stuck point 7 and teeth groove
The stress of Poly tooth bar 3 is not upper after 8 pinnings slides.
An indent slot structure is formed on the lateral wall of the upper pillar stand 1, tooth bar 3 is installed on the side wall of the indent slot structure,
An interior male structure is formed on the madial wall of lower pillar stand 2, the interior male structure is just stretched into the indent slot structure of upper pillar stand 1, deck 5 is installed
With the interior male structure towards on the surface of groove structure bottom surface side.
The function introduction of the vertical column expanding structure of the console television machine support is as follows：
1. when being adjusted up height, upper pillar stand 1 moves moved on band carry-over bar 3 upwards, and the meeting band moved fastener 4 of tooth bar 3 is automatic to return
Bullet, when the teeth groove 8 and open slot 16 on upper pillar stand 1 to tooth bar 3 and the stuck point 7 and salient point 6 on fastener 4 respectively to it is corresponding when fastener 4
Meeting self-return under the effect of spring force elastic force so that stuck point 7 and salient point 6 on fastener 4 slip into the He of teeth groove 8 of tooth bar 3 respectively
In open slot 16, upper pillar stand 1 is unclamped, during by the downward natural force of upper pillar stand 1, fastener 4 is engaged with tooth bar 3 and blocked, and is reached
Column 1 to the function of gliding, does not then lock the device of fastener 4, prevents fastener 4 from left-right rotation, plays safety effect；
2. regulation downwards：Downwards during regulation height, the fastener device (i.e. bolt) on fastener 4 need to be first opened, then rotated
Card makes stuck point 7 thereon and salient point 6 exit the teeth groove 8 and open slot 16 of tooth bar 3, fastener 4 is pulled then up, by fastener 4
On bulge-structure 13 move in the turning structure 14 of the end of arc-shaped hole 12 of deck 5, fastener 4 cannot automatic rebounding, this
When can freely adjust the height of upper pillar stand 1, when height regulation is to correct position, fastener 4 is pushed the circle that can be rotated automatically
In arcuate socket 12, fastener 4 will spring-loaded automatically reset and blocked with tooth bar 3, play positioning action, lock fastener dress again
Put.
