[0044] On the basis of the above embodiments, the technical features involved in the present application are further explained so that technicians in the technical field of the present invention can fully understand the technical features and technical solutions recorded in the present application and be able to reproduce them.

[0045] In the present application, the bed 8 is a hollow rectangular frame structure, and bed legs 7 are fixedly connected to the corners of the bed 8 , and the bed legs 7 can support and place the bed 8 .

[0046] The bed body 8 is provided with a plurality of groups of guardrail sockets 9 on the side, and a guardrail 3 is connected between each group of guardrail sockets 9. The guardrail 3 is higher than the surface of the bed body 8 to cooperate with the bed body 8 to protect the traction patient.

[0047] The bed body 8 is also fixedly connected with a leg connecting rod 15 between the bed legs 7 on the same side in the length direction, and the top surface between adjacent leg connecting rods 15 is fixedly connected with a bed bottom plate 14, and the bed bottom plate 14 is symmetrically provided with bottom plate guide drive holes 27 and slide rails, and a slider connected to the traction movable seat body 10 is provided on the slide rail, and a movable seat drive cylinder 29 is also installed on the bottom surface of the bed bottom plate 14, and the telescopic end of the movable seat drive cylinder 29 is connected to the movable seat connecting block 28 at the corresponding position, and the movable seat connecting block 28 is located inside the bottom plate guide drive hole 27 and can move along the bottom plate guide drive hole 27.

[0048] The movable seat connecting block 28 can move along the bottom plate guide driving hole 27 under the drive of the movable seat driving cylinder 29, thereby driving the traction movable seat 10 integrally provided therewith to move along the guide rail on the bed bottom plate 14.

[0049] The movement of the traction movable seat body 10 relative to the bed bottom plate 14 can make the traction plate bodies 4 connected thereto move individually or together in a direction away from the middle fixed block 5, thereby realizing the traction operation.

[0050] In the present application, a traction fixed block 11 is fixedly installed at one end of the traction movable seat body 10, and a traction guide slide rail 13 is also installed on the traction movable seat body 10, and a traction movable block 12 is slidably connected to the traction guide slide rail 13, and the traction movable block 12 moves relative to the traction guide slide rail 13.

[0051] The traction fixed block 11 and the traction moving block 12 are both fixedly connected with the jacking cylinder 18, and the traction fixed block 11 and the traction moving block 12 on both sides of the jacking cylinder 18 are respectively fixedly connected with the jacking guide rod 19, and the top of the jacking guide rod 19 is provided with a sleeve bottom plate 26, and the sleeve bottom plate 26 is processed with a through hole at the position corresponding to the telescopic end of the jacking cylinder 18, and the other end surface corresponding to the through hole is coaxially fixedly connected with a limiting sleeve 20, and a jacking connecting rod 21 is provided in the limiting sleeve 20, and the top of the jacking connecting rod 21 extends out from the limiting sleeve 20, and the bottom end of the jacking connecting rod 21 is connected to the telescopic end of the jacking cylinder 18. The jacking connecting rod 21 can extend into the interior of the traction connecting sleeve 22 under the action of the jacking cylinder 18 and connect with the traction connecting sleeve 22 or detach from the interior of the traction connecting sleeve 22 to achieve separation from the traction connecting sleeve 22.

[0052] The traction connecting sleeve 22 is symmetrically distributed at both ends of the traction plate body 4. The traction plate body 4 at the middle position of the traction connecting sleeve 22 is slidably set in the slide groove of the bed guide support plate 30 through a sliding protrusion, so as to realize sliding along the bed guide slide rod 24 under the support of the bed guide support plate 30.

[0053] The top of the traction plate body 4 is provided with a plurality of restraint connecting holes 16 distributed along its length direction. The restraint connecting holes 16 can be connected to the restraint through fasteners, and the restraint is used to connect the part to be pulled or the adjacent part, and traction is achieved under the movement of the traction plate body 4.

[0054] In the present application, since a traction fixed block 11 and a traction movable block 12 that moves relative to the traction fixed block 11 to achieve spacing adjustment are provided, a traction adjustment cylinder 17 is fixedly mounted on the traction fixed block 11, and the telescopic end of the traction adjustment cylinder 17 is connected to the traction movable block 12, and the distance adjustment between the two is achieved under the action of the traction adjustment cylinder 17.

[0055] The distance between the traction fixed block 11 and the traction movable block 12 is adjusted so that the jacking connecting rods 21 connected thereto can achieve different spacings. The different spacings between adjacent jacking connecting rods 21 can cooperate with the corresponding traction connecting sleeves 22 at different positions, thereby realizing the linkage between one or more traction plate bodies 4.

[0056] During the linkage process of the above-mentioned one or more traction plates 4, it will inevitably drive the traction plate 4 at the end to move when it is away from the middle fixed block 5, that is, the traction plate 4 connected with the traction end reset rod 25 to move. When the traction connection sleeve 22 is separated from the jacking connection rod 21, the traction end reset rod 25 can be pushed to reset the traction end reset rod 25 under the action of the reset spring in the reset spring cylinder 23, and the traction end reset rod 25 can also be used to push the end traction plate 4 away from the middle fixed block 5 to reset, and the end traction plate 4 can drive the rest of the traction plate 4 to reset to the initial position.

[0057] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
