It puts.
Preferably, Medicine applying bag is equipped between chest stretching device and stretching waist device；In stretching waist device
Portion sets ratchet device.
Original lying type by using shaft, can be drawn and changed by lumbar tractor provided by the utility model
For vertical traction, achieve the effect that traction therapeutic plus mechanical tensile forces using body weight.The ratchet mechanism set on shaft
Patient can be allowed to complete draw operations alone with retaining mechanism.The utility model delicate structure, cheap, easy to use, profit
In popularization.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the single supporting rod of the utility model；
Fig. 2 is the utility model overall structure diagram；
Fig. 3 is the utility model use state reference chart；

Specific embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
As shown in Fig. 1,2,4, a kind of lumbar tractor, including two symmetrically arranged shafts 10, in shaft 10
Bottom sets pedestal, support of the main part to provide of the diameter of pedestal greatly thereon, so that lumbar tractor is not
It can double swerve.In the top of shaft 10 setting liner 1, it is vertical to realize that liner 1 can be used to support the components such as the armpit of human body
Formula is drawn.One groove is set padding 1 bottom, is provided with internal thread；Correspondingly, outer spiral shell is set on the top of shaft 10
Line, the external screw thread on 10 top of shaft match to realize the spiral shell between liner 1 and shaft 10 with padding the internal thread of 1 bottom
Line connects.In the centre position of shaft 10, i.e. main part is also associated with chest stretching device 3 and stretching waist device 5,
In, chest stretching device 3 is arranged on main part upper position, and stretching waist device 5 is arranged on main part upper position, chest
Portion's stretching device 3 and stretching waist device 5 are connect by screw thread with shaft 10.It sets and locks in 3 upper end of chest stretching device
Locking apparatus 2 sets locking system 4 in its lower end.The main part of chest stretching device 3 and stretching waist device 5 is C words
Shape, two chest stretching devices 3 by be set to the straight line pole at C fonts both ends be joined together to form it is run-track shaped so as to hold
Receive human body, two stretching waist devices 5 by be set to the straight line pole at C fonts both ends be joined together to form it is run-track shaped from
And accommodate human body.Medicine applying bag 9 is equipped between chest stretching device 3 and stretching waist device 5.
Ratchet inner ring 64 in 5 middle part setting ratchet device 6 of stretching waist device, ratchet device 6 is equipped with internal thread simultaneously
It is screwed with 10 lower thread of shaft, pawl 63 passes through the outer ring ratchet of pawl wrench 62 and ratchet spring 61 and ratchet inner ring 64
Engagement.In 10 lower part of shaft, locking device 7 is set.
As shown in figure 3, lumbar tractor is placed on stool before use, shaft 10 surrounds human body wherein, and by
1 contact armpit of liner is so as to support human body.Rotatable liner 1 is so that tractor meets the height of human body；Chest is adjusted to draw
The relative altitude of device 3 and stretching waist device 5 is stretched, lumbar vertebrae is made to bear certain starting force.Pull the pawl on ratchet mechanism 6
Spanner 62, in pawl 63 under spring pressure by with 64 outer ratchet of ratchet inner ring engage drive ratchet inner ring 64 along
Screw thread rotation, when retracting pawl wrench 62, the inclined-plane of pawl 63 is jumped out from 64 outer ratchet of ratchet inner ring, constantly pulls pawl
Spanner 62 by the linear motion that the convert rotational motion of ratchet inner ring 64 is vertical direction, makes stretching waist device 5 in shaft
It is slided on 10, so as to generate pulling force.Ratchet rotation in ratchet mechanism 6, drives the operation downwards of stretching waist device 5, and waist is drawn
Distance is stretched between device 5 and chest stretching device 3 to suitable position.On the basis of body gravity, generate and keep certain
Extra traction, ratchet mechanism 6 have synchronizing function.After predetermined tractive force reaches, stretched in stretching waist device 5 and chest
Medicine applying bag 9 is fastened between device 3, is aided with treating lumbar diseases drug, physics traction is aided with drug therapy, is controlled so as to reach good
Therapeutic effect.
After patient treats for a long time, using retaining mechanism 7, the body of oneself can be dropped on stool, and make waist
Vertebra keeps certain tractive force, after treatment effect.And the spanner that whole process need to be only pulled on eccentric mechanism can be complete
Into.Treatment finishes, and releases waistband, packs up tractor, easy to operate.
The above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
