Abstract

The invention relates to a traction bed comprising a bedstead A, a bed board, a bedstead B and a bedstead C, wherein the bed board is connected to the middle of the bedstead A, and the bedstead B and the bedstead C are hinged on two sides of the bedstead A. The traction bed is characterized in that the bedstead B and the bedstead C are respectively provided with a towing board, and a driving mechanism for driving the towing board is installed between the towing board and the bedstead. The invention provides a physiotherapy rehabilitation traction bed which can be controlled by self, has simple structure and is practical and convenient.

Description

Extension table

Technical field

The present invention relates to a kind of extension table, be applicable to the home physiotherapy rehabilitation.

Background technology

Extension table is a kind of apparatus of physiotherapy and rehabilitation; Be widely used in various acute and chronic trauma cause in hospital or the medical institutions prolapse of lumbar intervertebral disc, walking is unable and cause the physical therapy of clinical symptoms such as legs and feet amyotrophy and cervical spondylosis, and be used for family voluntarily physiotherapy and rehabilitation extension table seldom.Existing extension table complex structure, expensive, function singleness can only position of physical therapy, can not carry out the physical therapy at a plurality of positions simultaneously.

Summary of the invention

The object of the present invention is to provide a kind of extension table, the present invention provides and can control voluntarily, and is simple in structure, convenient and practical physiotherapy and rehabilitation extension table.

The invention is characterized in: a kind of extension table; Comprise bedstead A and the bed board that is connected bedstead A middle part and the bedstead B and the bedstead C that are hinged on bedstead A both sides; It is characterized in that: said bedstead B and bedstead C install towing plate, and the driving mechanism that is used to drive towing plate is installed between said towing plate and the bed board.

Advantage of the present invention: 1) adopt the rack pinion transmission, be converted into rectilinear motion rotatablely moving, drive mechanism is simple, reliable and stable; 2) extension table can be folded into chaise longue or seat, can work as extension table, also can work as the household articles for use, does not take up room; 3) adopt handle and the draw-in groove that has straight pin, realize traction in various degree; 4) can realize a plurality of positions, like the traction in cervical vertebra, lumbar vertebra and shank joint.

Simple structure of the present invention, easy to operate, reliable and stable, cheap; Diverse in function can be controlled voluntarily, is applicable to that the patient carries out the traction physical therapy and the rehabilitation in cervical vertebra, lumbar vertebra and shank joint at home; Help neck lumbar vertebra patient away from slight illness, come into health, have wide development and application prospect.

The specific embodiment

With reference to legend; A kind of extension table; Comprise bedstead A and the bed board 1 that is connected bedstead A middle part and the bedstead B and the bedstead C that are hinged on bedstead A both sides;, it is characterized in that: said bedstead B and bedstead C install towing plate 2, and the driving mechanism 3 that is used to drive towing plate 2 is installed between said towing plate 2 and the bed board 1.

For the effect that realizes drawing; Said driving mechanism 3 comprises a rotating shaft 3-1; Said rotating shaft 3-1 one sidepiece be connected with one stretch out bed surface from bottom to top handle 3-2, thereby said rotating shaft 3-1 drives towing plate 2 through the gear driven mechanism 3-3 that is connected on the rotating shaft 3-1 with the tooth bar 3-4 that is fixedly connected on the gear driven mechanism 3-3.

In order to realize successive draw; Said handle 3-2 bottom passes the radially port 3-5 on rotating shaft 3-1 one side; Said handle 3-2 passes on top the handle port 4 of bedstead A side; Handle 3-2 side is provided with positioning of rotating bayonet lock 5, and said positioning of rotating bayonet lock 5 radially can block the draw-in groove 6 that is opened on bedstead port 4 inwalls during downward slippage of port 3-5 at handle 3-2 along rotating shaft 3-1.

In order to realize the traction to cervical vertebra, said bedstead B both sides are hinged with clamping rocking handle 7, and said rocking handle 7 lower ends are through the steady pin 8 mutually clamping of trapezoidal draw-in groove 7-1 with the corresponding side of bedstead A; Said bedstead B respective end is provided with a fixed muffle 9 and the sliding axle 10 that is mated use, and said sliding axle 10 1 terminations are provided with a pair of splayed support 11, and said support 11 is provided with pulley 12.

Motionless in order to fasten the person, said bedstead A, bedstead B and bedstead C are provided with belt 13.

Work process of the present invention is: the people lies in after the extension table, buckles belt, all has belt can fasten people's shoulder, waist and shank at the two ends of extension table, and the slip through plank realizes traction function; Swing the handle that has the positioning of rotating bayonet lock with hands, drive the rotation of the rotating shaft at the bed end, thereby make the gear driven mechanism transmission; Engaged transmission through gear driven mechanism and tooth bar; Drive tooth bar and move, slide thereby promote to have towing plate, thereby realize traction function to the both sides straight line.

The degree of traction during traction, needs handle to be fixed on certain position by the decision of handle rotation angle, is controlled by the positioning of rotating bayonet lock on the handle.When being drawn to certain degree, the pressed downward handle lets the positioning of rotating bayonet lock get in the draw-in groove, and the people just can let go like this, keeps the state of traction.When front haulage is worked as in cancellation, only need to swing a little forward or backward and upwards mention handle to get final product.

The above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to the covering scope of this patent.
