[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0034] Example 1:

[0035] As shown in the attached diagram, an adjustable fitness bed includes a bed frame 1 and two side frames 2. The side frames 2 adopt a U-shaped steel tube bending structure, which realizes the integrated molding design of the bed legs 21 and the guardrails 22. The square frame structure of the bed frame 1 and the two side frames 2 can be fixed by bolts. When the bed frame is made of steel or aluminum alloy, the three can also be fixed by welding. The above structure greatly simplifies the design, manufacturing and assembly process of the entire bed, improves manufacturing and assembly efficiency, and also reduces manufacturing costs.

[0036] The present invention has a guide part provided on the inner side of the bed body 1. In this embodiment, internal rails 11 are respectively provided on both sides of the bed body 1 as guide parts. A movable bed 3 is provided in conjunction with the internal rails 11. The bottom of the movable bed is provided with sliding wheels that cooperate with the internal rails 11 to achieve lateral guidance. Several tension springs 32 are provided between the movable bed 3 and the bed body 1.

[0037] More specifically, inside the bed body 1, on the left and right sides of the foot of the bed, near the internal track 11, there are positioning seats 14 respectively. The positioning seats 14 are provided with a number of positioning grooves 141. A tension spring positioning rod 15 is fixed in the positioning groove 141. The tension spring 32 is fixed between the tension spring positioning rod 14 and the tension spring fixing plate 31 on the bottom surface of the movable bed 3. When using the bed, the user can adjust the tension of the tension spring 32 by adjusting the tension spring positioning rod 14 in different positioning grooves 141.

[0038] The bed frame 1 is provided with an adjustment compartment 4 at its rear end. The bed frame 1 is provided with a handrail 5 at its rear end via a handrail hinge shaft 50. The handrail consists of a top force-applying handle 51 and side rods 52 on both sides. The side rods 52 are hinged to the bed frame 1 via the handrail hinge shaft 50. A swing link 53 is hinged to the side rod 52. The bottoms of the two swing links 53 are connected to a locking rod 54.

[0039] An adjustment chamber 4 is equipped with a pressure plate assembly 8, which includes a pressure plate 81. The pressure plate 81 is hinged to the adjustment chamber 4 via a pressure plate assembly hinge shaft 80 on its side. Several locking grooves 83 are provided on the side plate 82 of the pressure plate 81. A swing linkage 53 is hinged to the aforementioned handrail 5, and a locking rod 54 is fixed to the swing linkage 53. A horizontal guide groove 43 is provided on the side of the adjustment chamber 4, and the locking rod 54 moves within the horizontal guide groove 43. The locking rod 54 and the locking groove 83 are inserted and engaged to achieve a locking position. An clearance groove 41 is provided on the front side plate of the adjustment chamber 4, and a lifting handle 84 is fixed to the pressure plate 81. The lifting handle 84 passes through the clearance groove 41. With the above structural design, the user can lift the pressure plate 81 using the lifting handle 84. After lifting, the locking groove 83 separates from the locking rod 54. By pulling the force application handle 51 back and forth, the locking rod 54 moves back and forth within the horizontal guide groove 43 to achieve positioning. After stopping the movement, the pressure plate 81 presses down to achieve positioning. This utility model can quickly achieve positioning of the handrail 5 at multiple angles, and the positioning components are simple, easy to manufacture, and easy to assemble, reducing manufacturing costs while ensuring stable positioning.

[0040] This utility model also has a traction training function with the traction rope 70, such as Figure 1As shown, two uprights 12 are installed at the head end of the bed frame 1, and pull rope guide wheels 13 are installed on the top of each upright 12. A locking assembly is installed at the bottom of the movable bed 3. Figure 4 , 9 As shown, the locking assembly 6 includes a swing handle 61, which is L-shaped and hinged in the middle to the bottom of the movable bed 3. One end of the swing handle 61 is exposed to the outside for the operator to apply force, and the other end is hinged to a central drive plate 62. Side drive plates 63 are also hinged to the left and right sides of the central drive plate 62, respectively. The side drive plates 63 are symmetrically arranged and have the same connection structure as the outside. Specifically, an active clamping block 64 is hinged to the side drive plate 63, and the active clamping block 64 is connected to a driven clamping block 66 through a connecting plate 65. The purpose of this locking assembly 6 is to lock and fix the pull rope 70 to the movable bed 3, and to quickly adjust the length of the pull rope 70 according to the different users' force application habits. In use, force is applied to move the swing handle 61. The swing handle 61 pulls the central drive plate 62, causing the side drive plate 63 to move. When the side drive plate 63 drives the active clamping block 64, the active clamping block 64 squeezes the pull rope onto the driven clamping block 66. The pull rope 70 is clamped by both of them. An elastic recovery roller 69 is also provided on the rear side of the active clamping block 64 and the driven clamping block 66. The function of the elastic recovery roller 69 is to surround the pull rope and always provide a certain pulling force to the pull rope. When adjusting the length of the pull rope, the elastic recovery roller 69 pulls to achieve winding. The structural principle of the elastic recovery roller 69 is existing technology. It is equipped with a torsion spring inside, which drives the entire roller to rotate. This structure can be referred to in publication number CN218248316U, entitled "Internal Structure of an Adjustable Tensioner". The structural details are not described here.

[0041] To ensure that the pull rope always passes between the active clamping block 64 and the driven clamping block 66, this utility model, in conjunction with the locking assembly 6, provides guide ring I 67 and guide ring II 68 on the front and rear sides of the connecting plate 65, respectively. The two guide rings constrain the pull rope 70 to pass between the active clamping block 64 and the driven clamping block, preventing the pull rope 70 from swaying or shifting. This structure ensures the stability of the pull rope under stress and adjustment conditions.

[0042] Based on the technology of the above embodiments, the user can adjust the angle of the armrest 5 by adjusting the pressure plate assembly 8 during training. As a further technical extension, when leg pedaling training is required using the foot of the bed, a vertical end baffle 7 can be fixed on the adjustment compartment 4. This utility model provides a insertion hole 42 on the adjustment compartment 4 and an insertion rod 71 on the vertical end baffle 7. The insertion rod 71 is inserted into the insertion hole 42 to fix the vertical end baffle 7. The side of the vertical end baffle 7 facing the headboard is padded, which can realize the function of assisting leg pedaling.

[0043] In summary, this utility model, through various structural improvements, overcomes many shortcomings of the prior art. While ensuring the stability of its various functions, it achieves rapid adjustment of the armrest angle by 5 degrees and lock adjustment after rapid adjustment of the pull rope by 70 degrees, making it an ideal adjustable fitness bed.
