Abstract

The utility model is a first improvement for a chair cervical vertebrae tractor. The utility model adopts a sliding pair, which consists of a sleeve of a roof bar to replace a traditional wire rope pulley block structure. A rack and gear transmission mode with double locked ratchets is used to realize the lifting and the self-locking location of a top rod in the vertical direction. A demountable and foldable mode is adopted in the structure, which is greatly convenient for the transportation and the storage. The utility model has the advantages of simplified structure, simple self-operation and low cost, which are beneficial to the popularization and the application in families and office plates.

Description

Post rod type cervical traction chair

Technical field

This utility model belongs to a kind of medical machinery, specifically to the improvement of chair form cervical vertebrae traction machine.

Background technology

Along with social progress and development of science and technology, people's study is more and more heavier with mental work, and the thing followed is rolling up of cervical spondylosis.Except that the necessary medicine treatment, efficient assistant method is exactly a traction treatment to this class disease.So various types of traction devices arise at the historic moment.Wherein a kind of simple and practical be exactly the chair type cervical vertebra tractor.This apparatus is made up of the vertical lifting mechanism on seat and the fixed seat.The people is sitting on the seat, hangs forehead under the patient with cervical vertebra band, and the top suspender belt is fixed on the vertical lift structure, and upwards traction on cervical vertebra, reaches the purpose of treatment with the pulling force continuous action.What this vertical distraction mechanism adopted usually is that assembly pulley and steel wire rope are formed, and its driving device is made up of arm pivot post.Steel wire rope is wrapped in the rotating shaft, rotates by handle steel wire rope is tightened up, again by steel wire rope be positioned at seat frame top sheave group and realize the upwards action of traction.The haulage gear that this assembly pulley adds steel wire rope should use inconvenience, and the elasticity varicose of steel wire rope often causes operational error.Locking tweezers is big, and bad control, and cost is also higher, and installation and adjustment management, maintenance all are unsuitable for family and office application.

Summary of the invention

The purpose of this utility model is that the chair type traction apparatus for cervical vertebrae is done further improvement, particularly its vertical lifting mechanism is done more and is simplified practical improvement design, makes it all be applicable to family and office space more on from the cost to the structure.

Particular content of the present utility model is exactly the vertical lifting mechanism that the elevating mechanism of original steel wire rope transmission is improved to direct post rod type transmission.Its concrete design is exactly that the mechanism that is slidingly matched of a push rod and sleeve pipe composition is located on the seat.At driving mechanism of latter end configuration of push rod, this driving mechanism can slide push rod along sleeve pipe and forms vertical displacement movement.Be provided with the cross suspension gear of location cervical traction cover in the upper end of push rod, rise along with push rod directly produces along the slip of sleeve pipe vertical direction under the driving mechanism effect like this, just can finish traction cervical vertebra.Sleeve pipe and chair component directly fixedly become one, and will form a post rod type cervical traction seat.

Description of drawings

How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the structural representation of top rod driving mechanism.

Wherein, 1 is push rod, and 1A is the tooth bar of push rod hypomere side embedding, and 2 is sleeve pipe, 2A is the location-plate of the driving mechanism of sleeve pipe hypomere processing setting, and 3A is cross cross-arm hook, and 3B is the adjustable pipe box of suspension, 3C is a clamping screw, and 4 is the cervical vertebra suspender, and 5 is seat support, 6 for chair leans on, and 7 is back leg, and 5A is a seat board, 7A is a chair lower limb before the type, and 8 is driving handle, and 9 is release lever, 10 is driven wheel, and 11 are and two ratchet mechanisms of gear 10 interlocks, and 12 is turning cylinder.

The specific embodiment

After determining that this utility model vertical lifting mechanism is formed pair wire rope pulley that replacement the is traditional combination of sliding with push rod 1 and sleeve pipe 2, the structure that driving mechanism is taked is by the gear 10 that is embedded in the lateral tooth bar 1A of push rod hypomere and cooperates with tooth bar 1A, forms with two ratchet mechanisms 11 of gear interlock with the driving handle 8 of two ratchet interlocks and the lock handle 9 of another ratchet relieving mechanism.All mechanism is positioned on the location-plate 2A of hypomere on the sleeve pipe 2 by turning cylinder 12.

In above structural design, what the cross section of push rod 1 and sleeve pipe 2 was taked is the square-section, also can take the push rod of circular cross section and pipe box to match, and its principle also is the same.

Seat part among the design leans on 6 by sleeve pipe 2 and the chair that is positioned on the sleeve pipe 2, connects the back leg 7 that is positioned at sleeve pipe 2 lower ends, Before the type chair lower limb 7A and connect before back leg (7,7A) seat board 5A and locate superincumbent seat support 5 and form.Wherein the coupling part is all taked just to dismantle or is collapsible, is beneficial to storage and transportation.

Be fixed with a cross hitch in the upper end of push rod 1, form by regulating sleeve pipe 3B and cross cross-arm hook 3A, the scalable pipe box is provided with fastening bolt 3C, be used for adjusting and lock the position that the cantilever of cross cross-arm hook 3A leans out with decision, thereby guarantee vertically upward the pull strength of cervical region.

Take above structure can realize oneself's operation of patient easily.Put cervical traction cover 4 and be suspended on the cross cross-arm hook.Just sitting straight upright after, available hands is pressed driving handle 8, and the gear driven tooth bar is slowly risen push rod 1, arrive suitable traction dynamics after, automatically lock by ratchet mechanism.Available hand push lifts release lever after finishing traction, and the ratchet locking is opened, and push rod is driven power by automatic downslide.Because with handle 8 interlocks, the suspension apparatus falling head is limited, anti-very naturally locking hook casualty accident.Put in order in addition, transport, preserve conveniently, cheap, for the medical apparatus and instruments of this health extends to family and the office space is used, for a new road has been opened up in the control of cervical spondylosis.
