In case limited slip block is slidably.
In the present invention, upper locking piece one end passes through connector A and rod hinge connection, and the other end is cut with scissors by connector B with sliding block
Connect.
In the present invention, it is provided for installing the groove of scotch on sliding block.
In the present invention, when position-limit mechanism is locked, 90 ° of the angle convergence between upper locking piece and sliding block.
In the present invention, the locking of position-limit mechanism is spacing comprises the following steps that with unblock：
1）Locking is spacing
Spring is in compressive state, and its elastic force promotes sliding block, scotch and chute to produce the extruding force, the extruding force to prevent upper locking piece
During change state, sliding block, scotch are arbitrarily slided with respect to chute；When upper locking piece is separated with sliding block, connecting rod promotes sliding block and stop
Block is along slide；When upper locking piece and shoe contact, connecting rod pushes or pull on upper locking piece and produces extruding force to scotch, sliding block and
Scotch increases the extruding force of chute, and sliding block and scotch increase with respect to the force of sliding friction of chute, when connecting rod thrust or drawing
The timing of power one, with sliding block angle closer to 90 °, upper locking piece produces extruding force bigger scotch to upper locking piece, when 90 ° of angle convergence
When, upper locking piece produces extruding force convergence infinitely great scotch；When sliding block and scotch and the timing of coefficient of friction one of chute, slide
Block and scotch are made a concerted effort more than connecting rod in the component in chute direction with respect to slide friction, that is, realize that the locking of sliding block is spacing；
2）Unblock
Rotate upper locking piece to be separated with scotch, connecting rod promotes sliding block to slide, you can unblock.
Beneficial effect：The present invention can be used for the spacing of back and forth movement, by means of external force effect, may be implemented in any position in the range of certain
Put spacing, simple structure, be easily installed and safeguard.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to a kind of position-limit mechanism of Fig. 1 ~ Fig. 5, including chute 1, sliding block 2, scotch 3, upper locking piece 4, connecting rod 5, spring 6
And connector A7 and connector B8, wherein, the one end of upper locking piece 4 is hinged by connector A7 with connecting rod 5, and the other end passes through connector
B8 is hinged with sliding block 2, and scotch 3 is arranged in the groove set on sliding block 2, and sliding block 2 is arranged in chute 1, can be slided along chute 1
It is dynamic；The one end of spring 6 is connected with sliding block 2, and the other end is connected with scotch 3, and scotch 3 can be along the telescopic direction opposing slider 2 of spring 6
Slide, while into angle between upper locking piece 4 and sliding block 2；When spring 6 is in compressive state, its elastic force promotes sliding block 2, scotch 3
Extruding force is produced with chute 1, in case limited slip block 2 is slidably.
As shown in figure 3, spring 6 is in compressive state, its elastic force promotes sliding block 2, scotch 3 and chute to concrete operating principle
1 produces extruding force, and when the extruding force prevents upper locking piece 4 from changing state, sliding block 2, scotch 3 are arbitrarily slided with respect to chute 1；Lock
When block 4 is separated with sliding block 2, connecting rod 5 pushes or pull on sliding block 2 and scotch 3 is slided along chute 1, as shown in Figure 4, Figure 5, locks
When block 4 is contacted with sliding block 2, connecting rod 5 pushes or pull on upper locking piece 4 and produces extruding force, 3 pairs of cunnings of sliding block 2 and scotch to scotch 3
The extruding force increase of groove 1, sliding block 2 and scotch 3 increase with respect to the force of sliding friction of chute 1, when the thrust of connecting rod 5 or pulling force are certain
When, closer to 90 °, upper locking piece 4 produces extruding force bigger scotch 3 for upper locking piece 4 and the angle of sliding block 2, when 90 ° of angle theta convergence
When, upper locking piece 4 produces extruding force convergence infinitely great scotch 3；When sliding block 2 and scotch 3 are certain with the coefficient of friction of chute 1
When, appropriate angle theta is set, sliding block 2 and scotch 3 can be made to make a concerted effort more than connecting rod 5 in the side of chute 1 with respect to the sliding friction of chute 1
To component, that is, realize the locking limit function of sliding block 2；
