Referring to fig. 1-7, an orthopedic traction bed comprises a bed body 1, four support columns 2 are arranged at the bottom of the bed body 1, a first rope pulley 3 and a second rope pulley 4 are arranged at one end of the bed body 1, the first rope pulley 3 is positioned above the second rope pulley 4, one side of the first rope pulley 3 and one side of the second rope pulley 4 are matched with a same traction adjusting device 5, the top of the traction adjusting device 5 is connected with a first traction rope 6, and one end of the first traction rope 6, which bypasses the first rope pulley 3, is connected with a fixing clamp 7 connected with a part to be traction of a patient;

the bottom of the bed body 1 is provided with a third rope wheel 8, the bottom of the traction adjusting device 5 is connected with a second traction rope 9, and one end of the second traction rope 9 sequentially bypassing the second rope wheel 4 and the third rope wheel 8 is connected with a traction hammer 10. When the traction hammer 10 is in contact with the ground, the traction adjusting device 5 automatically pulls the second traction rope 9 upwards and drives the traction cone to hang in the air.

Clinically, the traction hammer 10 needs to be suspended from the ground and always give traction force to the part to be pulled of the patient. When the body position of the patient changes or the whole body slides along the direction of the traction force, the traction hammer 10 touches the ground, the counter traction force is reduced or disappears, and the traction effect is invalid. The above phenomena are particularly likely to occur during the rest period of the patient at night. At this time, once the traction hammer 10 touches the ground, the traction adjusting device 5 automatically pulls the second traction rope 9 upwards and drives the traction cone to hang in the air, thereby ensuring the continuation of the bone traction process.

In the above, the fixing clip 7 is a prior art, and can be connected with the part of the patient to be pulled. Furthermore, there is another implementation in which the traction shoe cover is worn by the patient's foot first, and then the retaining clip 7 cooperates with the traction shoe cover to impart a traction force to the patient's foot through the traction shoe cover.

Further, the fixing clip 7, the first sheave 3, the second sheave 4, and the third sheave 8 together form an "コ" shape. From another perspective, it is understood that the four components described above constitute four points to form a Contraband-like arrangement. Thereby giving the external force in the same direction to both ends of the traction adjusting device 5.

Further, the traction adjusting device 5 comprises an upper shell 11 matched with the first rope pulley 3 and a lower shell 12 matched with the second rope pulley 4, a same return spring 13 is connected between the upper shell 11 and the lower shell 12, the upper shell 11 and the lower shell 12 are both arranged in a hollow manner, a same slide rod 14 is connected in the upper shell 11 and the lower shell 12 in a sliding manner, and a hook 15 matched with one end of the second traction rope 9 is arranged at the bottom of the slide rod 14;

the sliding rod 14 is sleeved with a first spring 16, and the first spring 16 is located between the lower shell 12 and the sliding rod 14. One end of the first spring 16 is fixedly connected with the inner wall of the lower shell 12, the other end of the first spring 16 is fixedly connected with a fixing plate 17, one side of the fixing plate 17 is fixedly connected with the middle part of the sliding rod 14, and the other side of the fixing plate 17 is abutted against the inner wall of the lower shell 12.

When the traction hammer 10 is suspended from the ground and the sliding rod 14 is only matched with the lower shell 12, the first spring 16 is in a compressed state, and the upper shell 11 and the lower shell 12 are subjected to the same-direction external force, so that the return spring 13 positioned between the upper shell 11 and the lower shell 12 is subjected to the forced bending, and the upper end of the sliding block is pressed and clamped by the lower end surface of the upper shell 11 (see the detailed figure 6).

When the traction hammer 10 touches the ground, the upper shell 11 and the lower shell 12 are not subjected to the same outward force, then the return spring 13 is restored to be deformed under the action of the elastic potential energy thereof, and then the first spring 16 pushes the sliding rod 14 to move towards the upper shell 11, so that the second traction rope 9 is moved upwards and drives the traction hammer 10 to hang from the ground again (see fig. 3 in detail).

The essence of the application is that the traction direction formed by four points of the fixing clamp 7, the first rope wheel 3, the second rope wheel 4 and the third rope wheel 8 is skillfully utilized, so that two ends of the traction adjusting device 5 are subjected to equidirectional external force. It will be appreciated that the traction hammer 10 is suspended from the ground only when the two ends of the traction adjusting device 5 are subjected to a co-directional external force, so that traction force is present. Once the traction hammer 10 contacts the ground, when the gravity of the traction hammer 10 is borne by the ground, no traction force applies force to the two ends of the traction adjusting device 5, so that the two ends of the traction adjusting device 5 are adjusted by using the special structure of the traction adjusting device, and the second traction rope 9 is driven to move upwards and drive the traction hammer 10 to suspend above the ground again.

Further, the end of the upper shell 11 facing the lower shell 12 and the end of the lower shell 12 facing the upper shell 11 are provided with sockets 18, each socket 18 includes a fixing ring 19 slidably connected to the sliding rod 14, a butt block 20 is fixedly sleeved outside the fixing ring 19, and the butt block 20 can separate the fixing ring 19 into a threaded portion 21 and a socket portion 22. The fixing ring 19 is screwed to the upper casing 11/the lower casing 12 at one side of the screw portion 21, and the return spring 13 is sleeved outside the sleeved portion 22 of the fixing ring 19.

Specifically, one end of the return spring 13 is fixedly connected to the abutment block 20 located on the upper housing 11, and the other end of the return spring 13 is fixedly connected to the abutment block 20 located on the lower housing 12.

When the traction hammer 10 is suspended from the ground and the sliding rod 14 is only engaged with the lower shell 12, the first spring 16 is in a compressed state, and the upper shell 11 and the lower shell 12 are subjected to a co-directional external force, so that the return spring 13 between the upper shell 11 and the lower shell 12 is subjected to a forced bending, and the upper end of the sliding block is pressed and clamped by the lower end face of the fixing ring 19 of the upper shell 11 (see fig. 6 in detail).

Through the above arrangement, the present application has several technical purposes:

2. The end of the fixing ring 19 (the end facing the first spring 16) of the lower case 12 serves as a stopper for restricting the fixed plate 17 from coming out.

Furthermore, a limiting plate 23 for limiting the outward release of the sliding rod 14 is disposed at an end of the lower shell 12 away from the upper shell 11, and an end of the first spring 16 is fixedly connected to the limiting plate 23. A gap 24 for the hook 15 to be exposed outwards is arranged at one side of the limit plate 23 in a penetrating way.

Furthermore, a driving rod 25 penetrates through one side of the upper shell 11, a second spring 26 is sleeved at one end of the driving rod 25 in the upper shell 11, and the second spring 26 is located between the driving rod 25 and the upper shell 11. One end of the second spring 26 abuts against the fixing ring 19 on the upper housing 11, and the other end of the second spring 26 is provided with a driving plate 27, one side of the driving plate 27 is fixedly connected with the driving rod 25, and the other side of the driving plate 27 abuts against the inner wall of the upper housing 11. One end of the driving rod 25 is slidably connected to a fixing ring 19 provided on the upper case 11.

When one end (top) of the driving plate 27 abuts against the inner wall of the upper case 11, one end of the driving rod 25 is exposed to the outside of the upper case 11 (see fig. 3 in detail).

When the upper shell 11 and the lower shell 12 are simultaneously sleeved outside the sliding rod 14, the sliding rod 14 can be pressed downwards by pressing one end of the driving rod 25 until the sliding rod 14 is only matched with the lower shell 12. At this time, once the upper housing 11 and the lower housing 12 are under the action of the same-direction external force, the return spring 13 between the upper housing 11 and the lower housing 12 is forced to bend, so that the upper end of the slider is pressed and clamped by the lower end surface of the fixing ring 19 of the upper housing 11 (see fig. 6 in detail).

Further, the end of the upper housing 11 away from the lower housing 12 is provided with a connecting buckle 28 which can be matched with the first traction rope 6. The connecting buckle 28 and the driving rod 25 are independent and have no connection relationship.
