[0003] Fitness centers are usually equipped with display screens, where users can view or adjust running parameters such as mileage and speed. However, there are differences in height among users, so the display screen needs to have an adjustment mechanism for adjusting the pitch angle. Traditional adjustment mechanisms only manually loosen the bolts of the display screen, then manually rotate the display screen to reach the desired angle, and finally tighten the bolts to fix the display screen. However, most people do not have tools and do not have enough strength to turn the bolts, so users often choose to give up and use the original angle, resulting in very few people using the adjustment mechanism. Over time, the adjustment mechanism becomes abandoned.

DETAILED DESCRIPTION

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

[0034] The present invention provides a display screen position adjustment device on a fitness center armrest, comprising a pitch mechanism 1 and a rotation mechanism, such as Figures 4 to 6 As shown, the pitch mechanism 1 includes a first rotating motor 11, a first screw rod 12, and a first gear 13. Figure 1 , Figure 2 , Figure 3 and Figure 7 The fitness center includes an armrest 3, a display screen 4, a rotating shaft 5 and a frame 6. The armrests 3 are respectively arranged on both sides of the frame 6. The rotating shaft 5 is rotatably connected between the two armrests 3. The rotating shaft 5 is provided with a first bearing 15 at the rotating connection on the armrest 3. The display screen 4 is fixed on the rotating shaft 5. The first gear 13 is sleeved and fixed on the rotating shaft 5. A second bearing 14 is provided at the sleeve connection. The first gear 13 can be sleeved on the rotating shaft 5 and then connected to the rotating shaft 5 through a key. The first screw rod 12 is provided with an external thread that is threadably matched with the first gear 13. The first rotating motor 11 is connected and drives the first screw 12 to rotate.

[0035] The display screen 4 is detachably fixed on the rotating shaft 5. The detachable structure can be of various types. This embodiment adopts a relatively simple structure. The specific structure is as follows: a display screen mounting plate 41 is provided between the display screen 4 and the rotating shaft 5. The display screen 4 is mounted on the display screen mounting plate 41. The display screen mounting plate 41 is detachably fixed on the rotating shaft 5. The display screen mounting plate 41 includes a front shell 411 and a rear shell 412. The display screen 4 is mounted on the front shell 411. The front shell 411 and the rear shell 412 are covered together to form a cavity for accommodating the first rotating motor 11, the first screw 12, the first gear 13 and the rotating shaft 5. The adjustment mechanism 1 of this case can be designed inside the display screen mounting plate 41. The pitch angle of the display screen 4 is controlled by controlling the display screen mounting plate 41. The rotating shaft 5 passes through both sides of the display screen mounting plate 41 and is rotatably connected to the armrest 3.

[0036] The front shell 411 is integrally formed with a front half cover 4111 on the front half of the rotating shaft 5, and is separately formed with a rear half cover 4112 that is interlocked with the front half cover 4111. The front half cover 4111 is provided with a semicircular groove for accommodating the front half of the rotating shaft 5, and the rear half cover 4112 is provided with the same semicircular groove for accommodating the rear half of the rotating shaft 5; the front shell 411 is provided with screws, the front half cover 4111 is provided with a threaded hole, and the rear half cover 4112 is provided with a through hole at a position corresponding to the threaded hole, and the screw passes through the through hole and is tightly connected with the threaded hole, so that the rear half cover 4112 is fixed to the front half cover 4111. When it is necessary to disassemble the display screen 4, first open the rear shell 412, then loosen the screw, remove the rear half cover 4112, and finally remove the display screen 4 together with the display screen mounting plate 41 from the rotating shaft 5, which is very convenient. In this embodiment, a first dustproof housing 413 is further provided outside the first gear 13 and the first screw rod 12 to prevent dust from entering the threaded fitting portion between the first gear 13 and the first screw rod 12 .

[0037] In order to increase the stability of the structure, there are two front half covers 4111 and two rear half covers 4112 , which are respectively located on both sides of the back of the front shell 411 , and the first gear 13 is located on the rotating shaft 5 between the two front half covers 4111 .

[0038] like Figure 4 and Figure 5 As shown, the working process of the angle of the display screen 4 of the present invention is that the first rotating motor 11 rotates forward, driving the first screw 12 to rotate forward, and the first screw 12 drives the first gear 13 to rotate upward through the thread structure, so that the first gear 13 drives the display screen mounting plate 41 fixed on the same rotating shaft 5 and the display screen 4 to tilt upward. Conversely, the working process of the angle of the display screen 4 is as follows. Figure 6As shown, the first rotating motor 11 reverses and drives the first screw 12 to rotate in the opposite direction. The first screw 12 drives the first gear 13 to rotate downward through the threaded structure, so that the first gear 13 drives the display mounting plate 41 and the display screen 4 fixed on the same rotating shaft 5 to tilt downward, thereby realizing the adjustment of the pitch angle of the display screen 4.

[0039] like Figures 7 to 10 As shown, the rotating mechanism 2 includes a second rotating motor 21, a second screw 22, and a second gear 23. The display screen mounting plate 41 forms a cavity for accommodating the second rotating motor 21, the second screw 22, and the second gear 23. The second rotating motor 21 is fixed on the front shell 411.

[0040] The second rotary motor 21 is connected to and drives the second screw 22 to rotate. The second screw 22 is provided with an external thread that is threadedly matched with the second gear 23. The front shell of the display screen mounting plate 41 is provided with an axial hole 414. The back of the display screen 4 is provided with a convex shaft 42. During installation, the convex shaft 42 passes through the axial hole 414 and is fixedly inserted into the center hole 231 of the second gear 23. The convex shaft 42 is connected to the center hole 231 of the second gear 23 by a key. Then, a limit plate 43 is provided on the outer end surface of the convex shaft 42. The limit plate 43 is locked on the outer end surface of the convex shaft 42 by a screw (not shown in the figure). The limit plate 43 limits the axial movement of the second gear 23. Finally, a second dustproof housing 44 is provided on the outside of the second gear 23 and the second screw 22 to prevent dust from entering the threaded matching part of the second gear 23 and the second screw 22.

[0041] Combination Fig.11 The figure shows a schematic diagram of the display screen 4 of the present invention in a common state and not yet rotated. When the display screen 4 of the present invention needs to be rotated, the second rotary motor 21 is started to drive the second screw 22 to rotate, and the second screw 22 drives the second gear 23 to rotate through the thread structure, so that the second gear 23 drives the display screen 4 to rotate through the convex shaft 42. Fig.12 As shown, the electric control display screen 4 rotates; of course, Figure 6 What is shown is only a schematic diagram of the state after the display screen 4 is rotated 90 degrees. The rotation angle of the present invention can be arbitrary, so that the display screen 4 can be placed horizontally, vertically, or diagonally at various angles.

[0042] In addition, since the armrest 3 can rotate relative to the frame, the present invention also has the function of adjusting the up and down movement of the display screen 4. The armrest 3 drives the shaft 5 and the display screen 4 on the shaft 5 to move up and down to achieve height changes, further facilitating users to customize the position of the display screen.

[0043] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.
