[0004] Similar to the above-mentioned technical solutions, existing Pilates core beds adjust the tension by increasing or decreasing the number of springs, but adjusting the spring tension levels is not very convenient. Utility Model Content

[0005] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a Pilates core bed that allows for more convenient adjustment of the spring positions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A Pilates core bed includes a bed frame, a sliding plate, springs, and limiting rods. The sliding plate is horizontally slidably mounted on the bed frame along a first direction. Multiple sets of limiting grooves and a set of sliding grooves are symmetrically opened on both sides of the bed frame along the first direction, with the openings of the limiting grooves facing upwards. The limiting rod can be inserted into any set of limiting grooves. A slider is slidably mounted in the sliding groove, and a connecting rod is hinged to the slider. The two ends of the limiting rod are respectively connected to the connecting rods on both sides of the bed frame. The limiting rod and the sliding plate are connected by springs.

[0008] To better realize this utility model, the above structure is further optimized. The two sides of the bed frame are symmetrically provided with stop seats along the first direction, and the limiting groove is provided on the stop seats.

[0009] To better realize this utility model, the above structure is further optimized by setting four sets of limiting grooves at uniform intervals along the first direction.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Please refer to Figures 1-4The present application provides a Pilates core bed, including a bed frame 1, a sliding plate 2, a spring 3 and a limiting rod 4. The sliding plate 2 is horizontally slidably arranged on the bed frame 1 along a first direction. Multiple sets of limiting grooves 101 and a set of sliding grooves 102 are symmetrically opened on both sides of the bed frame 1 along the first direction, and the opening of the limiting grooves 101 faces upward. The limiting rod 4 can be inserted into any set of limiting grooves 101. A hook 401 is provided on the limiting rod 4, and the spring 3 is provided on the hook 401.

[0028] The slide groove 102 is set on the inner side of the bed frame 1. A slider 5 is slidably arranged in the slide groove 102, and a connecting rod 6 is hinged to the slider 5. The two ends of the limiting rod 4 are respectively connected to the connecting rod 6 on both sides of the bed frame 1. The limiting rod 4 and the slide plate 2 are connected by a spring 3 (only one spring is shown in the attached figure. In actual use, multiple springs are usually used in parallel). Since the slider 5 can only slide back and forth in the slide groove 102, it restricts the accidental movement of the limiting rod 4, making the operation safer and more controllable.

[0029] In this application, each set of limiting grooves 101 is equivalent to a gear position. The gear shift is completed when the limiting rod 4 engages in the corresponding limiting groove 101, thereby changing the spring tension between the limiting rod 4 and the sliding plate 2. This simplifies the method of adjusting the spring tension, allowing for multiple settings, which is more convenient than adjusting the tension by increasing or decreasing the number of springs.

[0030] In this embodiment, stop seats 11 are symmetrically arranged on both sides of the bed frame 1 along the first direction, and limiting grooves 101 are disposed on the stop seats 11. The stop seats 11 are fixedly connected to the bed frame 1 by bolts. The number of stops in the stop seats 11 can be adjusted by changing them. In this embodiment, the limiting grooves 101 are evenly spaced in four groups along the first direction, that is, there are four stops available for selection.

[0031] When shifting gears, pull the limit rod 4 upward to disengage it from the limit groove 101, then move the limit rod 4 and the slider 5 back and forth so that the limit rod 4 is aligned with the limit groove 101 of the corresponding gear, and press the limit rod 4 downward to lock it into the limit groove 101 of the corresponding gear, thus completing the gear shift.

[0032] Secondly, in this embodiment, the slide plate 2 and the bed frame 1 are connected by rollers 7 and guide wheels 8. In the prior art, due to frequent use of the slide plate 2, the rollers 7 and guide wheels 8 inevitably wear down, leading to problems such as uneven movement. Furthermore, because the screw heads are located internally, adjusting or replacing the rollers is inconvenient. Therefore, the technical solution adopted in this application is as follows: a support base 201 is provided at the bottom of the slide plate 2, and the rollers 7 and guide wheels 8 are all bolted and fixed to the outer side of the support base 201, so that the nuts of all fixing screws face outwards, thereby facilitating disassembly for adjustment, maintenance, and replacement.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
