Specific embodiment
Technical solution of the present invention is further elaborated with specific embodiment with reference to the accompanying drawing.
Referring to a kind of Fig. 1 to rehabilitation parallel bar shown in Fig. 3, this rehabilitation parallel bar includes that two groups of height are adjustable and parallel
The unilateral thick stick 1 being arranged.Unilateral thick stick 1 includes pedestal 2, the first support frame 3 and the second support frame 4, is set to the first support frame 3 and second
Handrail 5 on support frame 4.
First support frame 3 and the second support frame 4 include the fixed frame 6 being fixed on pedestal 2, can be high along fixed frame 6
Spend the crane 7 of direction sliding setting.Handrail 5 is set on two cranes 7, and two cranes 7 are able to drive in handrail 5
Lower movement.Preferably, guide rail is equipped between fixed frame 6 and crane 7, guide rail is extended along the short transverse of fixed frame 6,
Crane 7 can move up and down along guide rail, so that its movement is more steady.
Unilateral thick stick 1 further includes that one in the crane 7 for manipulate the first support frame 3 and the second support frame 4 moves up and down
Operating-controlling mechanism, for two cranes 7 to be synchronised the linkage mechanism of connection, connection of two cranes 7 in linkage mechanism
Under being capable of synchronization lifting.During adjusting unilateral thick stick 1, handrail 5 remains horizontality, avoids the production of handrail 5
Raw damage.
Below by taking the crane 7 that operating-controlling mechanism manipulates the first support frame 3 moves up and down as an example, the knot of unilateral thick stick 1 is described
Structure and lifting effect.It is emphasized that when the crane 7 for manipulating the second support frame 4 with operating-controlling mechanism moves up and down, it is single
The lifting effect of side thick stick 1 is identical, also within the scope of protection of this application.
Linkage mechanism includes the first fixed pulley assembly 9 and the second fixed pulley being arranged on the fixed frame 6 of the first support frame 3
10, the third fixed pulley 11 and both ends being arranged on the fixed frame 6 of the second support frame 4 are separately fixed at two cranes 7
The first traction rope 12 that is upper and successively bypassing the first fixed pulley assembly 9, the second fixed pulley 10, third fixed pulley 11.Preferably,
One fixed pulley assembly 9 is adjustably set to 6 lower end of fixed frame of the first support frame 3 along the short transverse height of the first support frame 3,
Second fixed pulley 10 is set to the top of the first fixed pulley assembly 9.The one end of first traction rope 12 bypasses the first fixed pulley assembly 9
Setting is upwardly extended, the upper end of the crane 7 of the first support frame 3 is fixed on;The other end of first traction rope 12 is around the
Three fixed pulleys 11 extend downwardly setting, are fixed on the lower end of the crane 7 of the second support frame 4.When operating-controlling mechanism manipulates first
When the crane 7 of support frame 3 moves upwards, the first traction rope 12 can pull the crane 7 of the second support frame 4 to synchronize upward fortune
It is dynamic.When the crane 7 that operating-controlling mechanism manipulates the first support frame 3 moves downward, the crane 7 of the second support frame 4 is due to self weight
It can synchronize and move downward.The crane 7 of second support frame 4 gives the crane 7 of the first support frame 3 by the first traction rope 12
One downward power.
In the present embodiment, the first fixed pulley assembly 9 includes first pulley seat 91, can rotationally set around own axes direction
In the first fixed pulley 92 on first pulley seat 91, the first bolt 93 that first pulley seat 91 can be fixed on pedestal 2, lead to
It crosses and turns the first bolt 93 and can adjust height of the first pulley seat 91 apart from pedestal 2, can control the first traction rope 12
Tightening degree, and then control relative altitude of two cranes 7 in fixed frame 6.
Linkage mechanism further includes the 4th fixed pulley 13 being arranged on the fixed frame 6 of the first support frame 3, is arranged at second
The 5th fixed pulley 14 and the 6th fixed pulley assembly 15 and both ends on the fixed frame 6 of support 4 are separately fixed at two liftings
On frame 7 and successively around the 4th fixed pulley 13, the 5th fixed pulley 14, the 6th fixed pulley assembly 15 the second traction rope 16.It is preferred that
, the 6th fixed pulley assembly 15 is adjustably set to the fixed frame 6 of the second support frame 4 along the short transverse height of the second support frame 4
Lower end, the 5th fixed pulley 14 are set to the top of the 6th fixed pulley assembly 15.The one end of second traction rope 16 is fixed around the 4th
Pulley 13 extends downwardly setting, is fixed on the lower end of the crane 7 of the first support frame 3;The other end of second traction rope 16
Setting is upwardly extended around the 6th fixed pulley assembly 15, is fixed on the upper end of the crane 7 of the second support frame 4.When manipulation machine
When the crane 7 that structure manipulates the first support frame 3 moves upwards, the first traction rope 12 can pull the crane 7 of the second support frame 4
It synchronizes and moves upwards.When the crane 7 that operating-controlling mechanism manipulates the first support frame 3 moves downward, the second traction rope 16 can be drawn
The crane 7 of dynamic second support frame 4, which synchronizes, to be moved downward.
6th fixed pulley assembly 15 includes second pulley seat 151, can be rotatably arranged in the second cunning around own axes direction
The 6th fixed pulley 152 on wheel seat 151, the second bolt 153 that second pulley seat 151 can be fixed on pedestal 2.By twisting
Dynamic second bolt 153 can adjust height of the second pulley seat 151 apart from pedestal 2, can control the receipts of the second traction rope 16
Tight degree, and then control relative altitude of two cranes 7 in fixed frame 6.
This unilateral thick stick 1 further includes that both ends are fixedly connected with 6 phase of fixed frame of the first support frame 3 and the second support frame 4 respectively
Connecting tube 17.Connecting tube 17 can play firm effect to unilateral thick stick 1.Meanwhile second fixed pulley 10, the 4th fixed pulley
13, third fixed pulley 11 and the 5th fixed pulley 14 are at the port of connecting tube 17, the first traction rope 12 and the second traction rope
16 both pass through the setting of connecting tube 17, and connecting tube 17 can play protection to the first traction rope 12 and the second traction rope 16, prevent him
People touches and influences the position of two cranes 7.Meanwhile in order to save space, saving material and be easily installed, the 4th fixed pulley
13 and second fixed pulley 10 rotate coaxially setting, the 5th fixed pulley 14 rotates coaxially setting with third fixed pulley 11.
In the present embodiment, operating-controlling mechanism is preferably self-locking air spring 8, is also possible to the energy such as pneumatic device, hydraulic device
Enough the device of driving crane 7 lifting is in the protection scope of the present embodiment.Self-locking air spring 8 includes gas spring ontology 81
Gentle snap switch 82.The both ends of gas spring ontology 81 are fixedly installed with fixed frame 6 and crane 7 respectively, gas spring switch 82
It stretches out fixed frame 6 to be arranged, be adjusted in order to operate.When inflate snap switch 82 when, gas spring ontology 81 can stretch;Work as closing
When gas spring switch 82, gas spring ontology 81 is locked.Preferably, the elastic force of self-locking air spring 8 and handrail 5, first support
The crane 7 of frame 3, the gravity of crane 7 of the second support frame 4 and identical.When opening gas spring switch 82, handrail 5,
The crane 7 of the crane 7 of one support frame 3 and the second support frame 4 remains static, and handrail 5 can be driven by external force
It is moved upwardly or downwardly.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
