Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a treadmill screen horizontal rotation mechanism and a treadmill. Background Technology

[0002] With increasing health awareness, treadmills have become common fitness equipment in homes and gyms. Modern treadmills are usually equipped with smart displays to show running data, play entertainment content, or offer online fitness courses. Currently, most treadmill screens are fixed to the handrails, with no adjustable viewing angle. Only the runner can view the screen, which is not something runners do while exercising, resulting in wasted resources. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a treadmill screen horizontal rotation mechanism foot machine, which can be equipped with a horizontally rotating screen, so that the screen can be used by other people and is applicable to more usage scenarios.

[0004] The technical solution adopted in this utility model is: a treadmill screen horizontal rotation mechanism, installed between the handrail tube and the screen support. The treadmill screen horizontal rotation mechanism includes a mounting box, a thrust bearing, a fixing component, a worm gear, and a worm. The seat ring of the thrust bearing is fixedly installed in the mounting box, and the worm gear is press-fitted into the shaft ring of the thrust bearing. The fixing component is clearance-fitted with the seat ring of the thrust bearing and is located in the mounting box below the seat ring. The fixing component and the worm gear are fixedly connected by fasteners. The rod part of the worm gear located inside the mounting box meshes with the worm gear. In the use state, the worm gear is fixedly installed at the bottom of the screen support, and the mounting box is fixedly installed on the handrail tube. The rotation of the worm gear drives the worm gear, the fixing component, and the screen support to rotate horizontally.

[0005] Preferably, the mounting box includes an upper cover and a lower cover that are fastened together. The seat ring of the thrust bearing is installed in the lower cover. The lower cover below the thrust bearing is provided with a mounting groove. A fixing member is provided in the mounting groove. The fixing member has an extension in the middle. The extension extends upward and passes through the seat ring and is connected to the worm gear through a fastener.

[0006] Preferably, a thrust pad is provided in the mounting groove, and the thrust pad is disposed between the mounting groove and the fixing member.

[0007] Preferably, the extension is connected to the worm gear by two fasteners.

[0008] Preferably, the treadmill screen horizontal rotation mechanism further includes a drive motor, which is connected to a worm gear transmission.

[0009] Preferably, the drive motor is a servo motor.

[0010] The treadmill includes handrail tubes and a screen bracket, and also includes the aforementioned treadmill screen horizontal rotation mechanism, wherein the screen bracket is rotatably mounted on the handrail tube via the treadmill screen horizontal rotation mechanism.

[0011] The beneficial effects of this utility model are as follows: The horizontal rotation mechanism of the treadmill screen of this utility model adopts a thrust bearing, which prevents the screen support from axial movement and ensures that the screen is stable and does not wobble during rotation. Furthermore, the drive mechanism of the drive motor, worm gear and worm can stop the screen at any angle, making it easy to adjust and allowing users to view and use the screen from multiple angles.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 5As shown, this embodiment provides a treadmill screen horizontal rotation mechanism, installed between the handrail tube 1 and the screen support 2. The rotation component includes a mounting box 3, a thrust bearing 4, a fixing member 6, a worm gear 5, and a worm 9. The seat ring of the thrust bearing 4 is fixedly installed in the mounting box 3, and the worm gear 5 is press-fitted into the shaft ring of the thrust bearing 4. The fixing member 6 is clearance-fitted with the seat ring of the thrust bearing 4 and is located in the mounting box 3 below the seat ring. The fixing member 6 and the worm gear 5 are fixedly connected by fasteners 602. The rod portion of the worm 9 located inside the mounting box 3 meshes with the worm gear 5. In the use state, the worm gear 5 is fixedly installed at the bottom of the screen support 2, and the mounting box 3 is fixedly installed on the handrail tube 1. The rotation of the worm gear 9 drives the worm gear 5, the fixing member 6, and the screen support 2 to rotate horizontally.

[0019] In this embodiment, the mounting box 3 includes an upper cover 301 and a lower cover 302 that are fastened together. The seat ring of the thrust bearing 4 is installed in the lower cover 302. The lower cover 302 below the thrust bearing 4 is provided with a mounting groove 3021. A fixing member 6 is provided in the mounting groove 3021. An extension 601 is provided in the middle of the fixing member 6. The extension 601 extends upward and is connected to the worm gear 5 through a fastener 602. A thrust flat pad 7 is provided in the mounting groove 3021. The thrust flat pad 7 is located between the mounting groove 3021 and the fixing member 6.

[0020] In this embodiment, the extension 601 is connected to the worm gear 5 by two fasteners 602. Preferably, the fasteners 602 in this embodiment are bolts.

[0021] This embodiment also relates to a treadmill, which includes a screen bracket 2 and a handrail tube 1, and also includes the above-mentioned treadmill screen horizontal rotation mechanism. The screen bracket 2 is rotatably mounted on the handrail tube 1 through the treadmill screen horizontal rotation mechanism.

[0022] The treadmill screen horizontal rotation mechanism in this embodiment also includes a drive motor 8, which is connected to the worm gear 9. During operation, the drive motor 8 is electrically connected to the treadmill's control system. The user can control the rotation angle between the screens through the control system. When the drive motor 8 starts, it drives the worm wheel 5 to rotate through the worm gear 9. The worm wheel 5 drives the screen support 2 to rotate. In this embodiment, the drive motor 8 is a servo motor.

[0023] The horizontal rotation mechanism of the treadmill screen in this embodiment uses a thrust bearing 4, which prevents the screen support 2 from axially shifting, ensuring that the screen rotates smoothly without shaking. It also uses a drive mechanism consisting of a drive motor 8, a worm gear 5, and a worm 9, which allows the screen to stop at any angle. The adjustment is convenient and allows users to view and use the screen from multiple angles.

[0024] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
