The tuck 41 includes swinging piece 411, swings 411 tail portion of piece and is provided with the insertion setting of 412 swing type of tuck column
In the tuck hole on the first rebound 4 head of sliding block, the head for swinging piece 411 is provided with tuck stick 413, and tuck stick 413 slides into certainly
Cooperate in locked groove 42 with it.
Working principle: as shown in Figure 1, 2, effect picture when being in close state for guide rail, in the closed state, first hangs
Button block 31 is connect with the first hanging buckle 51 being located on guide rail 5, and when user needs to open guide rail, firmly (inside) pressing is led to the left
It immediately looses one's grip after rail, pushes the first rebound sliding block 4 inwardly to move using the first hanging buckle 51, so that tuck 41 is detached from self-locking grooves 42,
At this point, first back-moving spring pulls the first buffer sliding block 3 and the first rebound sliding block under the pulling force effect of first back-moving spring 33
4 open to the right, so that pulling guide rail to rebound outward opens certain distance.
Wherein, when the first buffer sliding block moves, the driving of rack gear 6 on the first rebound sliding block 4 is located at the gear 61 on middle cover 1
Rotation, driving swing arm is swung when gear rotates, and driving torque arm is moved to the left when swing arm is swung, when torque arm moves downward, driving connection
Movable slider 64 moves downward in third sliding slot 65.
As shown in figure 3, second back-moving spring 53 pulls the second hanging block after the first hanging buckle block 31 is separated with the first hanging buckle 51
43 open to the right, and the second hanging block 43 pushes the second hanging buckle 52 on guide rail to outwardly open, and realize second segment when guide rail is opened
Rebound, so that the stroke that guide rail rebound is opened is increased, consequently facilitating the pumping that large-scale drawer guideway, more especially three sections are flexible
Drawer guide rail uses.As shown in Figure 6,7, end user pulls drawer until guide rail fully opens use.
As shown in Figure 8,9, when drawer guideway needs to close, user's (inside) pressing drawer guideway to the left, so that guide rail 5
On the second hanging buckle 52 first contacted with the second hanging block 43, the thrust that user applies pushes the second hanging block 43 is (inside) to the left to move,
At this point, under the guide pad 47 of hanging buckle sliding block 46 on the second hanging block 43 on it acts on so that guide pad 47 by the 4th sliding slot
12 enter in the 5th sliding slot 13, and hanging buckle sliding block 46 at this time sinks and 64 hanging buckle of catenating slider, therefore when the movement of the second hanging block 43,
Torque arm 63 and swing arm motion are driven by catenating slider 64,62 swing type of swing arm, driving gear 61 rotates, so that driving is nibbled with it
The rack gear 6 of conjunction moves along a straight line, and when rack gear 6 moves, the first rebound sliding block 4 is pushed inwardly to move.When the second hanging block 43 is led
Tuck and 42 hanging buckle of self-locking grooves when rail is pushed to inner dead point, on the first rebound sliding block.Wherein, the first rebound sliding block 4 is inwardly transported
When dynamic, change in location occurs between the first buffer sliding block 3, to stretch between the first rebound sliding block 4 and the first buffer sliding block 3
First back-moving spring 33 resets for guide rail buffering and makees preliminary preparation.
When user continues to close guide rail, the first hanging buckle 51 and the first hanging buckle block 31 on guide rail are hit, so that first hangs
Button block 31 deflects to be detached from out of 16 tail end of the 6th sliding slot locking sliding slot, and makes the first hanging buckle block 31 and the first hanging buckle 51
Docking, pulling force, the cushion dashpot 32 that the first back-moving spring 33 between the first buffer sliding block 3 and the first rebound sliding block generates at this time generate
Damping drive the first buffer sliding block to first rebound sliding block direction slowly move, thus drag guide rail and drawer buffering be reset to
Closed state.Wherein, after guide rail is closed, the first hanging buckle block 31 is appointed with the first hanging buckle 51 on guide rail is so in hanging buckle state, because
This can remain the state that drawer is closed, and avoid drawer from opening in the case where non-user operation, ensure that drawer is closed
Leakproofness and aesthetics afterwards, therefore can be widely used to promote.
Compared with traditional technology, unique linkage mechanism setting in this case, so that this guide rail is opened with press rebound, it is more
Long distance rebound is opened, and the effect of locking guide rail mentions while user-friendly after buffering is resetted and closed when closing
It rises user and uses texture, improve product specification, to have the higher market competitiveness.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.
