Specific embodiment
It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this
Utility model.
Referring to figs. 1 to Fig. 5, an a kind of embodiment of expansion bracket of the utility model is proposed, including several stand on ground
The flexible frame body kept a foothold, be connected between adjacent keep a foothold, flexible frame body hingedly forms by several telescopic units, telescopic unit
Including 2 cross-shaped hinged connecting rods 201, the junction of 2 connecting rods 201 in telescopic unit passes through the first articulated shaft
202 hingedly, carried out hingedly between the connecting rod 201 of adjacent telescopic unit by the second articulated shaft 203, connecting rod 201
It upper end and is carried out hingedly by third articulated shaft 204 between keeping a foothold, 201 lower end of connecting rod and passes through between keeping a foothold and lock machine automatically
Structure carries out hinged and locking.
It keeps a foothold including upright bar 101, be installed vertically on 101 lower end of upright bar and fit in the pedestal 102 on ground.
Automatic locking mechanism includes the block set being sheathed in upright bar 101, and block set includes the socket section being sheathed in upright bar 101
Points 301, set on the groove seating portion 302 of 301 lateral position of block set part, set on the locking seating portion of 301 lateral position of block set part
303, connecting rod 201 is installed in groove seating portion 302 and is carried out hingedly with groove seating portion 302 by the 4th articulated shaft 304,
It locks and is equipped with latch recess 305 in seating portion 303, automatic locking mechanism further includes the lock cylinder being embedded in latch recess 305
306, card insertion enters the dead bolt 307 that can be rotated in lock cylinder 306 and in lock cylinder 306, connect with 307 end of dead bolt
Unlock pull ring 308, dead bolt 307 be equipped with annular along side 309, automatic locking mechanism further include be set to lock cylinder 306 in
Side and annular between side 309 to dead bolt 307 have return effect reset spring, 101 medial surface of upright bar with
Lock hole 103 is equipped at the corresponding position of dead bolt 307.Lock cylinder 306 plays the role of 3, has installation dead bolt
307 effect, the reset spring in lock cylinder 306 play the role of return to dead bolt 307, and lock cylinder 306 is inserted for locking
The effect that pin 307 reverses inside it, in this way, can be inserted to locking even if manpower pulls dead bolt 307 with various angles
Pin 307 carries out drawing operation.Such novel and reasonable structure when needing to stretch expansion bracket, need to be only pulled open flexible frame body to most
Extended state, lock hole 103 is corresponding with dead bolt 307 at this time, and card insertion under the action of reset spring of dead bolt 307 enters
In lock hole 103, it is achieved that AutoLock feature, squats down without operator, goes debugging jack, locking behaviour without manpower
Make simple and fast.When needing to shrink expansion bracket, manpower is only needed to pull unlock pull ring 308 to make to unlock pull ring 308 with any angle
It pulls outward, so that dead bolt 307 be driven to be moved out out lock hole 103 outward, unlock operation can be completed, so that it may will
Expansion bracket is shunk, unlock operation simple and fast, it is seen then that lock operation and unlock operation all very simple and fasts, time saving province
Power, it is practical, and also operator can carry out drawing unlock pull ring 308 with any angle, carry out drawing without special angle,
Further simplify unlocking motion.
