Abstract

The utility model relates to a hand or motor driven traction table. The utility model is characterized in that a fixed bed bracket 1 is provided with a motor 9, a speed reducer 11, a clutch 13, a drive gears 15 and 16, a shaft roller 17, a rocker handle 7, and a drag rope 18, wherein, the clutch 13 is arranged on a decelerating transmission shaft 12 and the drive gears 15, the central shaft of the drive gears 15 is provided with the rocker handle 7, and the drive gears 16 is arranged on the shaft roller 17. The utility model adopts the clutch and the drag rope, and solves the problem that the exchange between the manual operation and the electric operation and the dragging operation are not smooth.

Description

The manual and electric dual-purpose extension table

This utility model belongs to a kind of medical apparatus and instruments, particularly the manual and electric dual-purpose extension table.

Traction therapeutic is that human synovial dislocation, dislocation reset, the common method of treatment of cervical spondylosis, lumbar spondylosis etc.And extension table is a kind of apparatus in the traction therapeutic apparatus.The version of extension table is varied, has to adopt the screw mandrel drive mechanism, the hydraulic drive structure, lever construction or the like.The useful electric control of device of these versions, also have manually.Owing to its structural reason, the traction therapeutic effect is not very good, and its shortcoming is an inconvenient operation, and drawing-in motion is not soft.Disclose the two-way transmission parallelogram of a kind of employing screw mandrel thruster as Chinese patent " multifunction traction physiotherapy bed " (Chinese patent application number 91226320.2) and made stretching motion, promote the relative slide displacement of slip bedstead, thereby play the traction purpose, but because this technical pattern more complicated, cost is also high, operate single, also light not too flexibly.

The new task of this practicality provides a kind of manual and electric dual-purpose extension table, and it can make manual operation and electric operating carry out conversion mutually easily.And can make operational motion soft, flexible to operation.

The new technical scheme of this practicality is such: a kind of manual, electric dual-purpose extension table that includes fixed bedstead, slip bedstead, drive mechanism composition, it is characterized in that on fixed bedstead, being equipped with motor, decelerator, clutch, travelling gear, beaming roller, crank, pull rope, clutch is installed on deceleration transmission axle and the travelling gear, on the travelling gear central shaft crank is set, travelling gear is installed on the beaming roller.

Clutch is then lived with manual separation connecting rod press-contacting type and is connected, and an end of connecting rod also links to each other with the jump ring bar.Be wound with pull rope on the beaming roller, a termination of rope is fixed on the bogie side frame of fixed bedstead, and the pulley on the slip bedstead is passed in another termination, is fixed on the middle bracket of fixed bedstead.On the one end frame of extension table slip bedstead tension meter is set, the other end is installed fixedly bedside rails and electric appliance control box on fixed bedstead.

Advantage of the present utility model has: owing to adopted manual and electric clutch drive mechanism device, can be easily to manual and electric operation implementation conversion, the operation light and flexible also owing to adopted beaming roller pull rope structure, makes drawing-in motion soft, and therapeutic effect is good.

Below in conjunction with embodiment and accompanying drawing this utility model is described in further detail.

Fig. 1 is this utility model embodiment shape assumption diagram.

Fig. 2 is this utility model example structure vertical view.

Concrete enforcement is as follows: make fixed bedstead 1, slip bedstead 2 with the shaped steel material earlier, slip bedstead 2 is slightly less than the bed frame of fixed bedstead 1, and is mobile so that slip bedstead 2 is cooperated on the bed frame of fixed bedstead 1.Install clutch 13 respectively on deceleration transmission axle 12 and travelling gear 15 axis, an end connection reducer 11 of deceleration transmission axle 12 fixedly installs deceleration transmission axle 12 and decelerator 11 on fixed bedstead 1 earlier.Install the travelling gear 16 that has the latch wheel earlier in a termination of beaming roller 17, then the beaming roller 17 that has travelling gear 16 is fixed on the fixed bedstead 1, the travelling gear 15 that is manufactured with crank 7 jacks is installed on the fixed bedstead 1, and clutch 13 is worked in coordination, travelling gear 15,16 intermeshes.Manual separation connecting rod 14 is installed again, and manual lever partly is placed on the side of extension table, separates shaft portion and will live and be connected, and work good with clutch 13, jump ring bar 8 formation press-contacting types.Jump ring bar 8 is placed on the side of extension table.On the frame of decelerator 11 fixed bedstead 1 nearby, install electronicly 9 again, link to each other with decelerator 11 wheel shafts with belt 10.Earlier around 5--8 circle steel wire rope 18, a termination of rope is fixed on the end frame of fixed bedstead 1 on beaming roller 17, and another termination is passed the pulley 19 that is fixed on the slip bedstead 2 termination framves and is fixed on fixed bedstead 1 middle bracket 20.The last tension meter 4 of installing on the cross-peen frame of slip bedstead 2 installs and fixes bedside rails 3 and electric appliance control box 5 at another cross-peen on fixed bedstead 1.

Operation operation of the present utility model is such: operation manual separation connecting rod 6, make clutch 13 connect travelling gear 15, open motor power, motor 9 rotates, after slowing down, decelerator 11 drives clutch 13, travelling gear 15 by deceleration transmission axle 12,16, beaming roller 17 is rotated, pull rope 18 draws slip bedstead 2 to a side shifting along with the rotation of beaming roller 17.If motor 9 counter-rotating, the bedstead 2 of then sliding moves to opposite side.If need not be electronic, change into manually, as long as stir manual separation connecting rod 6, make clutch 13 break away from travelling gears 15, on travelling gear 15, plug crank 7, both forward and reverse directions shakes, and slip bedstead 2 is moved as both forward and reverse directions.When moving to certain position, when reaching certain pulling force, need out of service, as long as stir the reversing that jump ring bar 8 just can block gear 16.
