Abstract

A cervical vertebra tractor mainly comprises a casing, hand wheels, mini bearings, pinions, main gears, ratchets, positioning plates, positioning wrenches, force measuring springs, pulleys, traction ropes, end sleeves, an arc transverse tube, a flexible traction part, gear shafts and flexible shoulder carriers, and is characterized in that gear reduction mechanisms are adopted, the purpose of inputting torque by rotating the handle wheels can be achieved, the cervical vertebra tractor is convenient and comfortable in use, rotation of the ratchets is controlled by adjusting the positioning plates through the positioning wrenches (see the figure 3) in axial angular asymmetric design so as to achieve positioned directional rotation of the gear mechanisms, the traction ropes wound on the pulleys are connected with the force measuring springs, traction force can be measured effectively, and the arc transverse tube and the casing are fixedly connected to form an arch support structure so that the cervical vertebra tractor is more stable and reliable in structure. The cervical vertebra tractor is easy in operation, easy in traction force control, and more flexible and convenient in use, and is especially suitable for family and office uses.

Description

Cervical vertebra tractor

Technical field

This utility model relates to a kind of treatment of cervical spondylopathy device, especially relates to a kind of cervical vertebra tractor.

Background technology

The cervical vertebra tractor of many treatment cervical spondylosiss has been arranged at present, had fixed and portable.The portable cervical vertebra tractor device volume that is fit to domestic is little, in light weight, as the patent No. of having announced is that the utility model patent of 03269137.8 (applying date is on July 21st, 2003) discloses a kind of portable cervical vertebra tractor, inconvenient operation when this traction apparatus shortcoming is traction wheel work lacks comfort; And need the very big drag torque of input, could regulate and guarantee has enough pull strengths to cervical region; And the size of very difficult control and demonstration pull strength; Also attractive in appearance inadequately, generous in appearance.

Summary of the invention

The purpose of this utility model mainly is to solve cervical vertebra tractor of the prior art inconvenient operation in use, and input service moment is big, and the problems such as size of very difficult control and demonstration pull strength also.

Above-mentioned technical problem of the present utility model is solved by following technical scheme.

This utility model mainly comprises housing, handwheel, miniature bearing, pinion, gear wheel, ratchet, spacer, dowelled spanner, dynamometer spring, pulley, pull rope, termination point casing, arc transverse tube, software drawing piece, gear shaft, flexible buttstrap, it is characterized in that: miniature bearing is housed in housing, mounting teeth wheel shaft on miniature bearing, gear wheel and pinion are installed on gear shaft, the gear reduction traction apparatus of being made up of miniature bearing, pinion, gear wheel, gear shaft is housed in housing; Fixedly hands is taken turns on the gear shaft of pinion; Fixed ratchet wheel on the gear shaft of gear wheel; Regulate control spacer, and then the positioning and directing of control ratchet rotates, the directed positioner of forming by ratchet, spacer and dowelled spanner by the dowelled spanner that is installed on the housing; Pull rope one end is fixed on the gear shaft, and the other end is walked around pulley and linked to each other with the software drawing piece, and dynamometer spring one end is fixed on the housing, and the other end links to each other with pulley, the device for measuring force of being made up of dynamometer spring, pulley, pull rope; The two-part housing in the left and right sides links to each other by the arc transverse tube, type arched supporting construction, and the termination point casing card passes the arc transverse tube, and is stuck on the housing; Flexible buttstrap interts in the lower end of housing.

Owing to this utility model gear reduction, obtain bigger pull strength thereby therefore can import less moment, adopt the handwheel design that meets ergonomics simultaneously, can reach the purpose of input torque by the rotation handwheel, easy to use, comfortable; Dowelled spanner by angled asymmetric design is vertically regulated spacer, thus the rotation of control ratchet, and the positioning and directing that finally reaches gear mechanism rotates; By pull rope around pulley and with being connected of dynamometer spring, can measure the size of pull strength effectively; Arc transverse tube and the housing arch support structures that has been composed of a fixed connection makes structure more firm, and is reliable.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings the technical solution of the utility model is described further.

Embodiment: referring to Fig. 1, Fig. 2 (a), Fig. 2 (b), Fig. 3, this utility model mainly comprises housing 1, handwheel 2, miniature bearing 3, pinion 4, gear wheel 5, ratchet 6, spacer 7, dowelled spanner 8, dynamometer spring 9, pulley 10, pull rope 11, termination point casing 12, arc transverse tube 13, software drawing piece 14, gear shaft 15, flexible buttstrap 16, it is characterized in that: mounting teeth wheel shaft 15 in housing 1, gear wheel 5 and pinion 4 are installed on gear shaft 15, gear wheel 5 and pinion 4 engaged transmission work, fixing handwheel 2 on the gear shaft 15 of pinion 4, by the turn to handwheel 2, input torque; Fixed ratchet wheel 6 on the gear shaft 15 of gear wheel 5 is regulated by the dowelled spanner 8 that is installed on the housing 1, control spacer 7, and then the positioning and directing rotation of control ratchet 6, and the positioning and directing that finally reaches control gear axle 15 rotates; Pull rope 11 1 ends are fixed on the gear shaft 15, the other end is walked around pulley 10 and is linked to each other with software drawing piece 14, dynamometer spring 9 one ends are fixed on the housing 1, the other end links to each other with pulley 10, the pull strength that passes on the pull rope 11 of pulley 10 can be reacted directly on the dynamometer spring 9, by the displacement of dynamometer spring, measure the size of pull strength.

Housing 1, handwheel 2, dowelled spanner 8, pulley 10, termination point casing 12, gear shaft 15 adopt injection molding; Pinion 4, gear wheel 5 are by extrusion process, cutting forming then; Miniature bearing 3 is standard components; Dynamometry bullet 9 springs adopt spring steel to make shaping; Spacer 7 adopts the steel plate drawing; Ratchet 6 can adopt injection molding or steel plate drawing; Pull rope 11 can adopt the software plastic ties; Software drawing piece 14 adopts lining or leather cutting, and sewing is made; Flexible buttstrap 16 adopts the nylon ribbon to be made.
