[0002] A stepper is a type of fitness equipment mainly used to simulate activities such as climbing mountains and stairs, making it an ideal choice for modern urban dwellers to exercise and stay fit.

[0003] However, the contact area between the current stepper and the bottom surface is relatively small. Especially now, steppers supported by handrails and tilt frames are prone to displacement during use. If the hinge between the handrail and the tilt frame becomes loose or breaks, it will directly cause the handrail or tilt frame to tip over, resulting in injury to the exerciser. Summary of the Invention

[0005] This utility model is achieved through the following technical solution: a stable support stepper structure, including a handrail, an inclined frame, and a pedal assembly mounted on the inclined frame. The handrail, inclined frame, and pedal assembly are combined to form a stepper. A base tube is installed at one end of both the handrail and the inclined frame. Rotating seats are rotatably installed at both ends of the base tube. A crossbar is installed on each rotating seat. A combined base rod is connected between the crossbars. The base rod, handrail, and inclined frame are combined to form a triangular support structure. Multiple support blocks are provided between the inclined frame and the base tube, and between the handrail and the base tube. Each support block protrudes from one end face of the crossbar to form a positioning part. A positioning groove is provided on the inner side of the crossbar opposite the positioning part. The positioning part is inserted into the corresponding positioning groove.

[0006] As a preferred technical solution, each end face of the support block is provided with a lead screw hole, one end of which extends into the positioning part. Lead screws are threaded into the longitudinally opposite lead screw holes. A rotating sleeve is installed in the middle of each lead screw. First bearings are installed at both ends of the rotating sleeve in the middle of the lead screw. The outer rings of the first bearings are installed on the bottom tube.

[0007] As a preferred technical solution, a second bearing is installed in the openings at both ends of the bottom tube, and a shaft is installed in the inner ring of each second bearing, with one end of the shaft being fixedly connected to the rotating seat.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a stable support structure for a stepper, including a handrail 1, an inclined frame 2, and a pedal assembly 3 mounted on the inclined frame 2. The handrail 1, the inclined frame 2, and the pedal assembly 3 are combined to form a stepper. A base tube 4 is installed at one end of both the handrail 1 and the inclined frame 2. Rotating seats 5 are rotatably installed at both ends of the base tube 4. A crossbar 6 is installed on each of the rotating seats 5. A combined base rod is connected between the crossbars 6. The base rod, the handrail 1, and the inclined frame 2 are combined to form a triangular support structure. Multiple support blocks 9 are provided between the inclined frame 2 and the base tube 4, and between the handrail 1 and the base tube 4. Each support block 9 protrudes from one end face of the crossbar 6 to form a positioning part 12. A positioning groove is provided on the inner side of the crossbar 6 opposite to the positioning part 12. The positioning part 12 is inserted into the corresponding positioning groove.

[0021] In this embodiment, each of the support blocks 9 has a lead screw 10 hole on one end face. One end of each lead screw 10 hole extends into the positioning part 12. Each of the longitudinally opposite lead screw 10 holes is threaded with a lead screw 10. Each lead screw 10 is equipped with a rotating sleeve 11 in the middle. Each of the two ends of the rotating sleeve 11 in the middle of the lead screw 10 is equipped with a first bearing. The outer ring of each first bearing is installed on the bottom tube 4.

[0022] In this embodiment, a second bearing 13 is installed in the openings at both ends of the bottom tube 4, and a shaft 14 is installed in the inner ring of the second bearing 13. One end of the shaft 14 is fixedly connected to the rotating seat 5.

[0023] In this embodiment, half-columns 8 are installed at opposite ends of the crossbar 6, and adjacent half-columns 8 are combined to form a connecting column. External threads are provided on the outer ring surface of the connecting column, and locking rings 7 are fitted on the outside of the connecting column. Internal threads are provided on the inner ring surface of the locking rings 7, and the locking rings 7 are connected to the external threads on the connecting column through the internal threads.

[0024] In this embodiment, the semi-columns 8 are arranged at different heights. The higher semi-column 8 is provided with a positioning plate that limits the locking ring 7. After the locking ring disengages from the lower semi-column, the positioning plate can limit the locking ring and prevent the locking ring from disengaging from the higher semi-column.

[0025] In this embodiment, one side of the support block 9 is respectively in contact with the handrail 1 and the tilting frame 2, while one end of the support block is in contact with the ground, so that the weight on the tilting frame and the handrail can be transferred to the ground through the support block, thereby applying a tilted support force to them.

[0026] In use, the rotating seat and crossbar can be rotated around the shaft until the crossbars are positioned opposite each other. At this time, the locking sleeve can be threaded onto the connecting column, thereby fixing the crossbars together to form a base bar. The base bar increases the contact area with the ground, and the combination of the base bar, tilting frame and handrail forms a triangular support structure, which increases stability.

[0027] To increase the stability of the handrail and tilting frame, the screw can be rotated by rotating the sleeve. The rotation of the screw drives the support block until it moves to the inside of the handrail and the bottom tube, as well as the inside of the tilting frame and the bottom tube. The positioning part on the support block can be inserted into the positioning groove of the crossbar, so that the support block is connected to the crossbar. This allows part of the weight of the handrail and the tilting frame to be applied to the support block, reducing the pressure between the handrail and the tilting frame and increasing safety during use.

[0028] In this configuration, after the support block moves inward, the positioning part can be moved out of the positioning groove, and after the locking ring disengages from the lower half column, the crossbars can be separated, and the crossbars can be raised around the axis until they are flush with the tilting frame or handrail, so that the handrail and tilting frame can be folded smoothly.

[0029] 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 changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
