As shown in Figures 1 and 2, the pulley gear 10 in one embodiment of the invention is used to be installed on the cavity 21 of proximate matter 20
It is interior.Pulley gear 10 includes shell 100, pulley mechanism 200, supports mechanism 300 and sliding rail 400.Shell 100 is hollow structure.
Pulley mechanism 200 is movably contained in shell 100.Mechanism 300 is supported to connect with one end of shell 100.Support mechanism 300
Including supporting piece 310.Supporting piece 310 along shell 100 width direction can Elastic Sliding, and can be with the cavity 21 of proximate matter 20
Madial wall elasticity abuts.Sliding rail 400 extends along the width direction of shell 100.Supporting piece 310 is slidably disposed in sliding rail 400
It is interior.
Above-mentioned pulley gear 10 supports mechanism 300 and sliding rail 400 by setting, supports the one of mechanism 300 and shell 100
End connection, support mechanism 300 include supporting piece 310, supporting piece 310 along shell 100 width direction can Elastic Sliding, sliding rail
400 along shell 100 width direction extend, supporting piece 310 is slidably disposed in sliding rail 400, so that pulley gear
The 10 madial wall elasticity that the cavity 21 of the supporting piece 310 of mechanism 300 and the proximate matter 20 of different size can be supported by it abut
Together, it realizes by the adjusting of the width to pulley gear 10 to be adapted to the use of the proximate matter 20 of different size, has very
Adaptivity well.
As shown in Figures 2 and 3, in one embodiment, further, supporting piece 310 is arranged in pairs.Two supporting pieces 310
It is respectively arranged at the opposite sides of 100 width direction of shell, and can be slided with respect to reverse sync.Two supporting pieces 310 can be same
Two madial wall elasticity opposite with the cavity 21 of proximate matter 20 are walked to abut.
It is arranged in pairs due to constituting two supporting pieces 310 for supporting mechanism 300, and two supporting pieces 310 are respectively set
In the opposite sides of 100 width direction of shell, and can be slided with respect to reverse sync so that two supporting pieces 310 can synchronize with
The opposite two madial wall elasticity of the cavity 21 of proximate matter 20 abut, to realize the symmetrical tune to 10 or so width of pulley gear
Section so that pulley gear 10 is capable of the cavity 21 of adaptive proximate matter 20, and symmetrical placed in the middle fixed, performance is stablized.
As shown in figure 3, further, it further includes gear 320 to support mechanism 300.Gear 320 is rotatablely arranged at shell
100 one end, and between two supporting pieces 310.The both ends of gear 320 are meshed with two supporting pieces 310 respectively, so that
Two 310 opposite shells 100 of supporting piece synchronous slide in opposite direction.
Distinguish opposite shell 100 when two supporting pieces 310 for supporting mechanism 300 to slide along the width direction elasticity of shell 100
When dynamic, since the both ends of gear 320 are meshed with two supporting pieces 310 respectively, in nibbling for the both ends of the gear 320 of relative rotation
It closes and is driven to descend to enable two 310 opposite shells 100 of supporting piece synchronous slide in opposite direction, so that two support
Part 310 can synchronize two madial wall elasticity opposite with the cavity of proximate matter 20 21 and abut.
It is understood that in other embodiments, it includes multiple to support mechanism 300 and sliding rail 400.It is multiple to support machine
300 opposite shell 100 of structure is spaced apart along the length direction of shell 100.Multiple sliding rails 400 support mechanism 300 one by one with multiple
It is corresponding.Specific set-up mode can be reasonably selected according to actual conditions, be filled with being adapted to the pulley with different pulley quantity
Set 10 actual use demand.
