Warning banner 334 is shown in red, i.e., when green is presented in display window 212, illustrates that grab 32 is in the lock state and (represent seat
Assembly is completed in chair 1), when red is presented in display window 212, illustrates that grab 32 is in the unlocked state and (represent seat 1 not completing
Assembly).
The working principle of the utility model is as follows:
(1) before assembling, as shown in figure 3, grab 32 is in the unlocked state, limiting slot 312 is not closed by the hook portion of grab 32,
Red is presented in display window 212, and the card column 11 of 1 bottom of seat setting is directed at limiting slot 312 and is inserted into, at this point, 1 bottom of seat is convex
If convex block 12 to button 35 apply pressure so that second spring e shrink, button 35 is retracted to immediately in groove 332, first
Under the action of spring d, drive rod 34 resets, and each grab 32 resets under the driving of drive rod 34, makes 31 turns of 32 opposite base of grab
Dynamic, the hook portion clamping lock of each grab 32 forms enclosed area b in card column 11, and by the closure of limiting slot 312, so that card column 11 be limited
In in the b of enclosed area, meanwhile, actuator 33 also generates displacement under the driving of grab 32, and green, instruction card is presented in display window 212
Hook 32 is in the lock state；
(2) before dismantling, as shown in Figure 4 and Figure 5, grab 32 is in the lock state, and the hook portion of grab 32 closes limiting slot 312
It closes, card column 11 is limited in the b of enclosed area, and green is presented in display window 212, the operation portion 331 of actuator 33 is pulled, in actuator
Under the action of 33, grab 32 generates displacement with respect to pedestal 2, rotates 32 opposite base 31 of grab, and the hook portion of grab 32 is detached from card
Column 11, meanwhile, button 35 is moved into limit hole 211, and when actuator 33 pulls in place, limit hole is inserted on the head of button 35
In 211, red is presented in display window 212 at this time, illustrates that grab 32 is in the unlocked state, since limit hole 211 is to button 35
Limit also can make grab 32 persistently keep unlocked state even if unclamping driving portion 33 at this time.
