However, when the pulley slides through the intersection of the two slide grooves, it cannot fit tightly against the inner wall of the slideway, which easily leads to unstable rotation of the rotating plate.

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings and are constructed and operated in specific directions. They are only for the convenience of describing the present technical solution and do not indicate that the devices or components referred to must have specific directions. Therefore, they should not be understood as limiting the present invention.

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Please refer to Figures 1 to 4 As shown, the rotation and translation mechanism includes a fixed plate 10, a rotating plate 20, a pulley 40, a magnetic member 60 and a connecting plate 30 located between the fixed plate 10 and the rotating plate 20, the connecting plate 30 is connected to the rotating plate 20 and is slidably connected to the fixed plate 10, the rotating plate 20 has a first surface 20a and a second surface 20b relative to each other, the first surface 20a refers to the surface of the rotating plate 20 facing the connecting plate 30, the second surface 20b refers to the surface of the rotating plate 20 facing away from the connecting plate 30, and the second surface 20b of the rotating plate 20 is connected to the rotating cabinet, and the surface of the fixed plate 10 facing away from the connecting plate 30 is connected to the fixed cabinet. When the rotating cabinet is driven to rotate, the rotating plate 20 is driven to rotate relative to the fixed plate 10. Since the connecting plate 30 is connected to the rotating plate 20 and is slidably connected to the fixed plate 10, the connecting plate 30 is driven to rotate by the rotating plate 20 and can slide relative to the fixed plate 10, thereby having a rotation and translation effect.

[0027] Specifically, two slide grooves 21 extending along the first direction X are provided on the first surface 20a. The two slide grooves 21 are symmetrical about the center line of the rotating plate 20 and are connected to form a closed slideway. A pulley 40 is slidably provided in the slideway. The outer surface of the pulley 40 is in rolling contact with the inner wall of the slideway, and the pulley 40 is connected to the fixed plate 10. That is to say, when the rotating plate 20 is driven by the rotating cabinet to rotate, the fixed plate 10 is in a fixed state, and the pulley 40 is connected to the fixed plate 10. The pulley 40 will not move. The rotating plate 20 is only rotated to cause the slideway on the rotating plate 20 to cause the pulley 40 to produce relative displacement, thereby realizing the change of the position of the pulley 40. In addition, the rotating plate 20 can slide relative to the fixed plate 10 through the connecting plate 30, so that the rotating plate 20 can produce the effect of rotation and translation relative to the fixed plate 10. It should be noted that the above-mentioned first direction X refers to the direction of translation of the rotating plate 20. For details, please refer to Figure 1 The X direction in .

[0028] The pulley 40 is made of a magnetic material. The magnetic material can be a magnet or other magnetic metal material, and there is no limitation on this. The magnetic member 60 is connected to the second surface 20b, and the projection of the magnetic member 60 on the first surface 20a is located at the outer edges of both ends of the slide, which is used to apply an adsorption force to the passing pulley 40 so that the pulley 40 is close to the inner wall of the slide. It should be noted here that the magnetic member 60 can specifically be a magnet, but is not limited to this. It can also be a component that can apply an adsorption force to the pulley 40 passing through the intersection of the two chutes 21.

[0029] In this embodiment, a magnetic member 60 is provided on the second surface 20b, and the projection of the magnetic member 60 on the first surface 20a is located on the outer surface of the slide. In addition, the pulley 40 is made of magnetic material, so that the pulley 40 passing therethrough is pressed against the inner wall of the slide by the magnetic force generated by the magnetic member 60, thereby avoiding the problem of not being able to press against the inner wall of the slide, resulting in an unsmooth passage through the intersection of the two slide grooves 21, thereby causing unstable rotation of the rotating plate 20.

[0030] In one embodiment, a protrusion 70 is provided on the second surface 20b. The protrusion 70 is located at the outer edge of the projection of the two ends of the slideway on the second surface 20b, and the protrusion 70 defines a mounting cavity, and the magnetic member 60 is mounted in the mounting cavity. In other words, by providing the protrusion 70 with a mounting cavity on the second surface 20b, the magnetic member 60 can be installed in the mounting cavity.

[0031] Furthermore, the magnetic member 60 includes multiple magnetic blocks, which are installed in the mounting cavity at intervals. This allows for replacement of a magnetic block due to a drop in magnetic properties, eliminating the need to replace all of the blocks, thus saving costs. It should be noted that the term "multiple" refers to two or more, depending on the specific situation.

[0032] In one embodiment, a cover plate 120 is further included, and a frame 50 connected end to end is provided around the outer edge of the second surface 20b to form a storage cavity 70a on the second surface 20b. The protrusion 70 is located in the storage cavity 70a, and the cover plate 120 is used to cover the storage cavity 70a.

[0033] In one embodiment, a mounting block 110 is provided on the second surface 20b, and a mounting hole 120a is defined in the cover plate 120 for mating with the mounting block 110. After the cover plate 120 is placed over the receiving cavity 70a, the mounting block 110 is aligned with the mounting hole 120a. Fasteners (e.g., screws) can then be inserted through the mounting hole 120a and the mounting block 110 to secure the cover plate 120 to the rotating plate 20. This provides a simple structure and facilitates subsequent assembly and disassembly.

[0034] In one embodiment, the chute 21 is formed by the first surface 20a being recessed toward the second surface 20b, and the thickness of the pulley 40 is less than or equal to the depth of the chute 21. Specifically, the thickness of the pulley 40 needs to be less than or equal to the depth of the chute 21 to ensure that the pulley 40 is completely positioned within the chute 21, preventing it from jumping out while being driven to move within the chute 21, thereby ensuring normal rotation of the rotating plate 20. For example, if the thickness of the pulley 40 is greater than its depth, the pulley 40 may jump out of the chute 21 while moving along the trajectory of the chute 21, thereby preventing subsequent rotation from proceeding normally.

[0035] In one embodiment, the intersection of the two chutes 21 is in an arc-shaped transition. In this way, when the pulley 40 switches from one chute 21 to another chute 21, the transition can be performed smoothly, avoiding the problem of being stuck or unable to switch.

[0036] In one embodiment, the device further includes a slide rail 80 and a slider 90. The slide rail 80 is provided on the surface of the fixed plate 10 facing the connecting plate 30 and extends along the first direction X. The slider 90 is slidably connected to the slide rail 80 and is connected to the connecting plate 30. In other words, when the connecting plate 30 is driven to translate, the connecting plate 30 can move linearly along the predetermined direction of the slide rail 80, thereby making the translation of the connecting plate 30 smoother.

[0037] In one embodiment, stoppers 100 are provided on the surfaces of both ends of the slide rail 80 to prevent the slider 90 from separating from the slide rail 80. In this way, the stoppers 100 provided at both ends of the slide rail 80 limit the sliding distance of the slider 90, thereby preventing the slider 90 from falling off the slide rail 80 and preventing subsequent translation.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
