Description

Technical Field

[0001] The utility model relates to the technical field of traction equipment, in particular to a hand-cranked traction bed. Background Art

[0002] A traction bed is a medical device that uses mechanical transmission for traction. Combining the characteristics of human physiology and mechanical physics and mechanics, it is widely used in various symptoms such as lumbar disc herniation and low back pain caused by acute and chronic injuries.

[0003] In the prior art, the traction method is usually manual traction by people. During the traction process, it is difficult to control the magnitude of the traction force, and it is inconvenient to adjust the traction according to needs. The above-mentioned manual traction method can no longer meet people's needs for traction.

[0004] Therefore, a multi-functional hand-cranked belt traction bed for cervical vertebra, lumbar vertebra, scapulohumeral periarthritis and lumbar sprain has become an urgent problem to be solved in the whole society. Content of the Utility Model

[0005] In view of this, in order to solve the problems in the technical background, the utility model provides a hand-cranked traction bed, and the specific technical solutions are as follows:

[0006] A hand-cranked traction bed includes a bed body. One end of the bed body is provided with a traction mechanism. The traction mechanism includes a wire winding disc, a hook and a hand crank. A traction wire is wound on the wire winding disc. One end of the traction wire is provided with a hook, and a hand crank is arranged on the side wall of the wire winding disc. The rotation of the hand crank drives the wire winding disc to rotate, thereby tightening the traction wire.

[0007] Further, one end of the bed body is provided with a first bed board, and the other end is provided with a second bed board. The height of the second bed board is less than the height of the first bed board. The height of the first bed board is 30 cm, and the height of the second bed board is 25 cm. Patients with lumbar spondylosis and patients with lumbar and ankle sprains sit at one end close to the first bed board, and patients with cervical spondylosis and scapulohumeral periarthritis sit at one end close to the second bed board.

[0008] Further, an adjusting board is obliquely placed at one end of the bed board close to the second bed board. The back of the adjusting board is rotatably connected to a connecting rod through a hinge. The connecting rod is connected and fixed to a fixing frame through a bolt. The fixing frame is vertically arranged on the side wall of the bed board. A plurality of small holes are equidistantly formed on the connecting rod. The bolt passes through the fixing frame and the connecting rod and then is fixed.

[0009] Further, one or more fixed pulleys are arranged below the bed body, and the traction wire passes through the fixed pulleys.

[0010] Further, through holes are formed on the second bed board.

[0011] Adopting the above technical solution, the following beneficial effects are achieved:

[0012] The utility model is used in cooperation with a bed body, a traction mechanism, etc., and is combined with a first bed board, a second bed board, an adjusting board, a fixed pulley connecting rod, etc. By manually rotating the hand crank, the tightness of the traction wire can be adjusted, and the flexibility is relatively high. It is used to treat symptoms such as cervical spondylosis, lumbar sprain, scapulohumeral periarthritis, and ankle sprain and fracture. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1: Refer to Figure 1-2 the shown traction bed. The overall length is 190 cm, of which the length of the bed body 1 is 150 cm, the width is about 35 cm, and the height is 46 cm. There are two types of bed boards with different heights at both ends of the bed, namely the first bed board 4 and the second bed board 5, which are 30 cm and 25 cm respectively. The overall dimensions of the traction mechanism are 20 cm in height, 11 cm in width, and 40 cm in length. The material of the bed body 1 is steel.

[0018] A manual traction bed, comprising a bed body 1, one end of the bed body 1 is provided with a traction mechanism, the traction mechanism includes a wire winding disc 2, a hook 3 and a hand crank 11, a traction wire is wound on the wire winding disc 2, one end of the traction wire is provided with a hook 3, the side wall of the wire winding disc 2 is provided with a hand crank 11, and the hand crank 11 rotates to drive the wire winding disc 2 to rotate so as to tighten the traction wire. One end of the bed body 1 is provided with a first bed board 4, and the other end is provided with a second bed board 5. The height of the second bed board 5 is less than that of the first bed board 4. The height of the first bed board 4 is 30 cm, and the height of the second bed board 5 is 25 cm. Patients with lumbar spondylosis and those with sprained waist and sprained feet sit at one end close to the first bed board 4, and patients with cervical spondylosis and scapulohumeral periarthritis sit at one end close to the second bed board 5. An adjusting board 6 is obliquely placed at one end of the bed board close to the second bed board 5. The back of the adjusting board 6 is rotatably connected to a connecting rod through a hinge, the connecting rod is connected and fixed to a fixing frame 8 through a bolt, the fixing frame 8 is vertically arranged on the side wall of the bed board, a plurality of small holes are equidistantly opened on the connecting rod, and the bolt passes through the fixing frame 8 and the connecting rod and then is fixed. One or more fixed pulleys 9 are arranged below the bed body 1, and the traction wire passes through the fixed pulleys 9. A through hole 7 is opened on the second bed board 5.

[0019] This embodiment further includes a traction garment used together during traction. The traction garment is made of canvas belt.
