The specific embodiment
In order to understand the technique scheme of this utility model better, be explained in further detail below in conjunction with accompanying drawing and embodiment.
First embodiment of the manual self-adjustable cervical vertebra tractor of this utility model is sitting type structure, and is as shown in Figure 1.In the present embodiment, in the upper end of traction frame 1 fixed pulley 2 is installed; Fixed pulley 2, movable pulley 4 and pull rope 3 couplings are formed 3 fixed 3 running blocks, and on the cross-arm 5 that movable pulley 4 is installed in, pillow jaw suspender belt 6 is suspended on the cross-arm 5, constitutes the traction hitch; Pull rope 3 passes flexible pipe 7 and is connected to ropewinder 8.The traction frame bracing or strutting arrangement of present embodiment is an altitude mixture control connecting rod 9, and the structure of altitude mixture control connecting rod 9 is as shown in Figure 2.The top of altitude mixture control connecting rod 9 is provided with a plurality of altitude mixture control hole, and the installing hole of the bottom of traction frame 1 is connected with bolt or alignment pin with one of them altitude mixture control hole, and the control traction frame is to suitable height.The base 10 of present embodiment is common folding seat, and two installing holes of the bottom of altitude mixture control connecting rod 9 are fastened on bolt on the chair back of folding seat, forms the traction frame bracing or strutting arrangement of sitting type structure.
According to the needs of user, base 10 also can adopt chaise longue, couch, bed or other suitable seat furniture for sleeping in, and altitude mixture control connecting rod 9 is connected on the base 10, forms the manual self-adjustable cervical vertebra tractor of sitting posture, reclining posture or horizontal type structure.
Guide function by flexible pipe 7; Come pull rope 3 can regulate the pull strength and the draft travel of the manual self-adjustable cervical vertebra tractor of this utility model easily to any direction, the installation of ropewinder 8 and operating position no longer receive the restriction of the assembly pulley position and the pull rope direction of motion.
Ropewinder 8 is made up of handle 11, wheel shaft 12 and handle stop 13, and is as shown in Figure 3.Handle stop 13 is the alignment pin or the bolt that assemble spring 14, and its effect is a lock handle 11 after pull strength and draft travel adjusting completion, prevents that pull rope is loosening in the distraction procedure.
Another embodiment of the manual self-adjustable cervical vertebra tractor of this utility model is shoulder formula supporting construction, and is as shown in Figure 4.Traction frame bracing or strutting arrangement in the present embodiment is a shoulder back bracket frame 16, and the bottom of traction frame 1 directly is fixed on the shoulder back bracket frame 16, forms the manual self-adjustable cervical vertebra tractor of shoulder formula supporting construction.The traction hitch of present embodiment is identical with first embodiment, repeats no more at this.
By the guide effect of flexible pipe 7, user can use ropewinder 8 to regulate pull strength and draft travel in any position easily.User can utilize the holds handle 15 on the ropewinder 8 to hold ropewinder 8, and turning handle 11 coiling pull ropes 3 are regulated draft travel and pull strength, and the manual self-adjustable cervical vertebra tractor that has solved shoulder formula supporting construction is not easy to install and fix the problem of ropewinder.
Though the traction hitch of the manual self-adjustable cervical vertebra tractor of the foregoing description adopts 3 fixed 3 running blocks, yet the traction hitch of the manual self-adjustable cervical vertebra tractor of this utility model also can adopt 4 fixed 4 running blocks; Can know that by physics knowledge the stroke of 3 fixed 3 running blocks and 4 fixed 4 running block pull ropes is 6～8 times of movable pulley stroke, that is to say that the control accuracy of draft travel can improve 6～8 times; The pull rope pulling force be pull strength that assembly pulley produces be 1/6～1/8, if wheel shaft 12 winding radius of ropewinder 8 are 1/5 of handle 11 radiuss of turn, the power of turning handle is 1/30～1/40 of pull strength.Conventional according to medical treatment; Vertebrae traction recovering is treated required pull strength and is 10kg to the maximum; The operator of the manual self-adjustable cervical vertebra tractor of this utility model need use the power turning handle of 250～300g at most, just can regulate draft travel and pull strength easily.Even do not use ropewinder, the operator also only needs the power pulling traction rope about 1kg, just can regulate draft travel and pull strength, realizes manual self-regulated cervical traction function.
Another embodiment of the manual self-adjustable cervical vertebra tractor of this utility model is the radius of turn of the handle 11 of lengthening ropewinder 8; Be generally about one times of lengthening; The single raise binder is used for fixing shank on the base of seat, on cross-arm 5, hangs a secondary breast shoulder belt and is used to entangle shirtfront and back.The manual self-adjustable cervical vertebra tractor of this utility model is used as lumbar tractor.
Those of ordinary skill in the art will be appreciated that; Above embodiment only is the technical scheme that is used for explaining this utility model; And be not the qualification that is used as this utility model; As long as in the connotation scope of this utility model, all will drop in claims scope of this utility model variation, the modification of the above embodiment.
