DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. The described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0029] Example 1:

[0030] Please refer to the drawings Figure 1 and Figure 2The cantilever mechanism of this utility model can serve as a carrier for the human-machine interaction system in equipment, especially in roller pressing equipment. The cantilever mechanism is easy to use and can meet the needs of different application scenarios.

[0031] The cantilever mechanism of this utility model includes a rotating base 1, which is specifically a circular base. A cantilever 2 is rotatably mounted on the rotating base 1. The cantilever 2 includes a shaft 21, which passes through the rotating base 1 and is rotatably connected to the rotating base 1. In some specific embodiments shown, the shaft 21 passes vertically through the rotating base 1. The cantilever 2 uses the shaft 21 as the center of rotation, and the shaft 21 can rotate freely around its axis.

[0032] A rotating structure 3 is provided between the shaft 21 and the rotating seat 1. The rotating structure 3 includes an axial bearing 31 and a radial bearing 32. The axial bearing 31 and the radial bearing 32 are both sleeved on the shaft 21 and are coaxially arranged. The axial bearing 31 and the radial bearing 32 are both arranged inside the rotating seat 1. In some specific embodiments shown, the radial bearing 32 is located above the axial bearing 31. The radial bearing 32 and the axial bearing 31 are spaced apart. The shaft 21 can maintain stable rotation through the combined action of the radial bearing 32 and the axial bearing 31.

[0033] A locking component 33 is provided between the shaft 21 and the rotating seat 1 for locking the shaft 21. When the cantilever 2 rotates to a suitable angle, the locking component 33 can restrict the rotation of the shaft 21 and realize the positioning of the shaft 21.

[0034] In a preferred embodiment, the cantilever 2 includes a rod 22 connected to a shaft 21. Specifically, the cantilever 2 can be made of stainless steel tubing, which helps to enhance the structural strength and corrosion resistance of the cantilever 2.

[0035] In a preferred embodiment, a touchscreen 5 is provided at the end of the rod 22 away from the shaft 21. In some specific embodiments, the touchscreen 5 includes a button plate 51 and a back plate 52, with a hinge 54 connecting the button plate 51 and the back plate 52. The button plate 51 is connected to the rod 22, and a tubular handle 53 for the operator to grip is provided on the back plate. During actual operation, the operator can send commands to the main device through the control interface of the touchscreen 5 to monitor the working status of the main device in real time.

[0036] When the operator needs to adjust the operation angle of the touch screen 5, the operator drives the rod body 22 to rotate through the touch screen 5, and the rod body 22 drives the shaft body 21 to rotate relative to the rotating seat 1. In the rotating process of the shaft body 21, the axial bearing 31 can bear the axial load and limit the axial movement of the shaft body 21, thereby ensuring the stability of the rotation of the shaft body 21. The radial bearing 32 can bear the radial load of the shaft body 21 and transmit the radial load to the rotating seat 1, thereby reducing the radial friction in the rotating process of the shaft body 21 and ensuring the smoothness and stability of the rotating action of the shaft body 21. The coaxial arrangement of the axial bearing 31 and the radial bearing 32 can effectively improve the stability and accuracy of the rotation of the cantilever 2, ensure that the operator can accurately operate at a suitable angle, reduce the rotation deviation of the cantilever 2, and thereby reduce the operation failure rate caused by the rotation error and eliminate the potential safety hazard caused by the insufficient accuracy in the rotation adjustment of the cantilever 2.

[0037] Embodiment 2:

[0038] The difference between this embodiment and embodiment 1 is that the rotating structure 3 of the utility model is further optimized in this embodiment. Please refer to Figure 2 .

[0039] The axial bearing 31 of this embodiment is preferably but not limited to a thrust ball bearing, and the radial bearing 32 is preferably but not limited to a deep groove ball bearing. The radial bearing 32 is provided in multiple numbers and is spaced and sleeved on the shaft body 21 and located in the rotating seat 1. As shown in some specific embodiments, the radial bearing 32 is provided in two numbers. It can be understood that this is not a specific limitation on the number of radial bearings 32, and a person skilled in the art can adjust it according to actual needs.

[0040] In the preferred embodiment, a dust isolation structure is arranged between the two radial bearings 32. Specifically, a groove 211 is formed in the outer wall of the shaft body 21, which is an annular groove formed along the rotating direction of the shaft body 21 and located between the two radial bearings 32. The dust isolation structure includes a first dust isolation sheet 34 arranged in the groove 211. The first dust isolation sheet 34 can reduce the influence of dust on the radial bearing 32, thereby ensuring the accuracy of the radial bearing 32.

[0041] Further, a second dust isolation sheet 35 is arranged between the radial bearing 32 and the axial bearing 31. Specifically, the second dust isolation sheet 35 is an annular sheet sleeved on the outer side of the shaft body 21. The second dust isolation sheet 35 can reduce the influence of dust on the axial bearing 31, thereby further ensuring the rotation adjustment accuracy of the rotating structure 3.

[0042] In the preferred embodiment, the shaft body 21 is provided with an anti-abrasion sheet 212 at one end in the axial direction. When assembled, the cable passes through the anti-abrasion sheet 212 into the shaft body 21 and is inserted into the rod body 22 by the shaft body 21, and finally is electrically connected with the touch screen 5. The anti-abrasion sheet 212 can protect the cable. When the cantilever 2 rotates, the cable inside is easily damaged. The anti-abrasion sheet 212 can reduce the direct contact between the cable and the shaft body 21, thereby improving the problem of cable damage caused by long-term wear of the cable and the cantilever 2, and ensuring the normal operation of the equipment.

Specifically, the limiting plate 41 can be a convex plate, etc. The rod body 22 includes a contact portion 221 in contact with the limiting plate 41. When the rod body 22 rotates to the contact portion 221 in contact with the limiting plate 41, the limiting plate 41 limits the continued rotation of the rod body 22.

[0046] Please refer to Figure 5 , in the preferred embodiment, the limiting plate 41 includes a limiting end 411, and the limiting plate 41 is provided with a stop bolt 42 at the limiting end 411.

When the rod body 22 drives the contact portion 221 to rotate to the limiting end 411, the stop bolt 42 is in contact with the contact portion 221 to limit the continued rotation of the rod body 22. The stop bolt 42 is threadedly connected with the limiting end 411. By adjusting the length of the stop bolt 42 screwed into the limiting end 411, the rotation angle range of the rod body 22 can be adjusted to flexibly change the maximum rotation angle of the rod body 22 to meet the needs of different application scenarios. At the same time, when the rod body 22 rotates to the limit position, the limiting assembly 4 plays a limiting role for the rod body 22, which can effectively reduce the possibility of collision between the cantilever 2 or the touch screen 5 and the main equipment, thereby reducing the mechanical damage of the cantilever 2 mechanism and protecting the personal safety of the operator.
