Description

Technical Field

[0001] The utility model relates to the technical field of treadmills, in particular to a folding structure of a treadmill column and a treadmill. Background Art

[0002] With the improvement of people's living standards and the promotion of national fitness, users have an increasing demand for treadmills. There are many types of treadmills. Among them, foldable treadmills are more suitable for indoor use. They take up less space and are deeply loved by users.

[0003] A foldable treadmill usually has foldable columns. There are many types of folding structures. For example, the applicant's earlier patent application CN114796990A discloses a folding mechanism for a treadmill and a treadmill, which uses an eccentric handle to lock the treadmill column. However, during actual use, the applicant discovered the following disadvantages of this structure:

[0004] When a user grabs the treadmill column handrail while running, the treadmill column handrail will swing back and forth to some extent. This shaking process can easily cause the handle to loosen. Once the handle is loose, the treadmill column will be difficult to effectively support. Only by fully fastening the handle during operation can the occurrence of such situations be reduced. Due to the characteristics of this type of handle itself, it is inevitable that the user will not fasten the handle into place during actual use. For this reason, the applicant filed this application. Utility Model Content

[0033] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] See also Figures 1-6 The folding structure of the treadmill column includes a treadmill frame 1. The corresponding first axis 11 and second axis 12 are fixed on the left and right sides of the treadmill frame 1 respectively, wherein the first axis 11 is used to cooperate with the support unit 2, and the second axis 12 is used to cooperate with the column unit 3, so that the corresponding column units 3 and the corresponding components for locking the column units 3 are respectively arranged on the left and right sides of the treadmill frame 1. The upper ends of the two column units 3 can jointly support the column handrails 31 for users to hold on to. Of course, the column handrails and the two column units can be integrally formed or can be locked and connected by fasteners.

[0035] The second shaft 12 is arranged at a more forward position of the treadmill frame 1 relative to the first shaft 11, and the column unit 3 is rotatably configured on the second shaft 12 so that the column unit 3 can rotate relative to the second shaft 12. As one of the options, after the second shaft 12 passes through the hole at the lower end of the column unit 3, the column unit 3 can be positioned laterally by a fastener threadedly connected thereto, so that the flipping angle of the column unit 3 is more accurate.

[0036] In this embodiment, a third shaft 13 is fixed on the column unit 3 above the position that cooperates with the second shaft 12. The third shaft 13 is rotatably connected to one end of the support unit 2. As one of the options, after the third shaft 13 passes through the hole at one end of the support unit 2, the support unit 2 can be positioned laterally by a fastener threadedly connected to it.

[0037] As mentioned above, the other end of the support unit 2 cooperates with the first shaft 11. In this embodiment, the support unit 2 includes a movable groove 21, and the outer end of the first shaft 11 is configured at the movable groove 21. The movable groove 21 provides a movable space for the first shaft 11. Through the cooperation between the first shaft 11 and the movable groove 21, the support unit 2 and the first shaft 11 form a sliding fit connection. When the column unit 3 is in the expanded state, the first shaft 11 is located at the lower end position of the movable groove 21. Figure 2 When the column unit 3 is in the folded state, the first shaft 11 is located at the upper end of the movable groove 21, as shown Figure 6 shown.

[0038] As one option, the outer end of the first shaft 11 includes a fitting hole 111 , and a positioning member 112 for laterally positioning the support unit is assembled at the fitting hole 111 , and the positioning member 112 and the fitting hole 111 are connected by threaded fit or interference fit.

[0039] As one option, the movable groove 21 is a straight groove, and its width is adapted to the outer diameter of the first shaft 11 , so that the cooperation between the movable groove 21 and the first shaft 11 provides a guide for the flipping of the column unit 3 .

[0040] After the column unit 3 is unfolded, it needs to be locked to provide a stable and reliable handhold for users who are running. In this embodiment, a fourth shaft 14 is fixed to the support unit 2, and the positioning unit 4 is rotatably connected to the fourth shaft 14. As one option, the fourth shaft 14 can be fixed at the top of the lower end of the support unit 2.

[0041] The positioning unit 4 includes a positioning portion 41 and a toggle portion 42. The positioning portion 41 is used to cooperate with the first shaft 11. After the column unit 3 is unfolded, the first shaft 11 is located at the lower end of the movable groove 21. At this time, the positioning unit 4 is flipped down, and the outer edge of the positioning portion 41 contacts the first shaft 11 until the positioning unit is snapped into place. The first shaft 11 supports the positioning portion 41. The direction of the supporting force of the first shaft 11 on the positioning portion 41 is the same as or close to the inclination direction of the support unit 2, and the positioning of the positioning portion 41 by the first shaft 11 can ensure that the positioning unit cannot be flipped up and unlocked without human operation. Not only is the locking effect good, but the locking is more stable. At the same time, the locking operation is simple.

[0042] As one option, the positioning portion 41 is a sheet-like component, which is arranged between the support unit 2 and the treadmill frame 1, and the toggle portion 42 can be arranged above the support unit 2. It can be integrally formed with the positioning portion 41. When the positioning unit is flipped down to its locked state, the lower side wall of the toggle portion 42 is attached to the upper side wall of the support unit 2 to improve the overall positioning effect.

[0043] To facilitate the unlocking operation, in this embodiment, one end of the toggle portion 42 can be appropriately extended outward. Specifically, when the positioning unit is in the locked state, at least part of the toggle portion 42 extends outside the support unit 2, that is, at this time, the outer end of the toggle portion 42 has a portion 421 that does not overlap with the support unit. Figure 3 As shown, this part is convenient for the user to flip it up and unlock it.

[0044] Since the positioning unit moves from top to bottom during the locking operation, in this embodiment, the lower wall 412 of the outer edge 411 of the positioning portion 41 is designed as a sloped wall or an arc wall so that it can be more smoothly inserted into the space defined by the first axis.

[0045] As one option, the outer edge of the positioning portion 41 includes a positioning step 413, and the positioning step 413 can be formed by cutting the upper end of the lower wall of the outer edge of the positioning portion, such as Figure 5 As shown, the upper end of the lower wall 412 on the outer edge of the positioning portion transitions to a sloped wall inclined toward the inner side of the positioning portion. The sloped wall serves as a positioning step, and the wall 414 above the sloped wall can be a sloped wall or an arc-shaped wall.

[0046] The size of the positioning part only needs to be able to be effectively supported by the first axis after buckling. For details, please refer to Figure 3 shown.

[0047] A treadmill comprises the above-mentioned column folding structure, and a treadmill platform is arranged on the treadmill frame.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
