The utility model content
Technical problem to be solved in the utility model is to overcome defect and the deficiency existed in prior art, and a kind of domestic back traction device is provided, and this retractor structures is simple, and dismounting and convenient in carrying can realize spinal column dragging treatment at home.
This utility model is to address the above problem adopted technical scheme to be: domestic back traction device, comprise framework, screw rod and hands wheel, described framework is comprised of the upper frame relatively be set in together and underframe, described screw rod is set in framework along the suit direction of upper frame and underframe, one end of screw rod is provided with for the fixing step of upper frame, the two ends cooperation that screw rod stretches out framework is provided with nut, be arranged with the worm gear with the inner nut structure matched with screw thread on it on screw rod, described handwheel is fixed on underframe, be fixedly connected with on underframe and be useful on the fixedly fixed mount of worm gear, handwheel rotates by controlling the worm screw arranged that is meshed with worm gear, realize the motion of worm gear on screw rod.
The described underframe structure that takes the shape of the letter U, the two ends of underframe are provided with for being set with the cover tankage of upper frame.
Described handwheel drives worm screw by the parallel-crank mechanism be in transmission connection with it and rotates, and this parallel-crank mechanism can make the setting position of handwheel move outward, is convenient to the user operation.
The cross section of described screw rod one end is square, in the upper frame that end is connected therewith or underframe, is provided with the square opening coordinated with screw clearance, and such setting can reduce the degree of freedom of bolt rotary, makes this traction apparatus in use, and screw rod does not rotate.
This utility model in use, with fixing band through four jiaos of framework, this traction apparatus is fixed on to human body back, by rotating handwheel, drives worm screw and rotate, worm screw with the worm gear engaged transmission of inner nut structure, worm gear moves on screw rod, and when worm gear moves down along human body back, the spacing between upper frame and underframe widens, because whole traction apparatus is fixed on human body back, finally cause that the back spinal column is opened.
Beneficial effect: this domestic back traction device is by the combined complete of upper frame and underframe, this upper and lower framework can be fixed on to human body back, rotation by handwheel, realize the worm and gear engaged transmission, and then realize the motion of worm gear on screw rod, can realize the traction therapeutic to the human spine, simple to operate; This retractor structures is simple, is convenient to dismounting and carrying, and cost is low, can realize people's self-auxiliary treatment at home.
