[0028] Please refer to Figure 1 , Figure 2 and Figure 3 , the utility model embodiment provides a kind of medical equipment 100 including at least one cantilever assembly 1, main shaft component 2 and at least one limit component 3;At least one cantilever assembly 1 is set on the outer periphery of main shaft component 2, and is electrically connected with main shaft component 2;At least one cantilever assembly 1 is configured to rotate around main shaft component 2;At least one limit component 3 is connected with main shaft component 2, and at least part of limit component 3 is located on the track of cantilever assembly 1 rotating around main shaft component 2;At least one limit component 3 is configured to limit the one-way rotation of cantilever assembly 1 around main shaft component 2.

[0029] The utility model embodiment provides a kind of medical equipment 100, which includes at least one cantilever assembly 1, main shaft component 2 and at least one limit component 3.Cantilever assembly 1 is set on the outer periphery of main shaft component 2, and can rotate around the outer periphery of main shaft component 2, by being provided with limit component 3 on main shaft component 2, the rotation of cantilever assembly 1 can be limited, prevent the one-way rotation of cantilever assembly 1 around main shaft component 2 from causing the breakage of wire connected between cantilever assembly 1 and main shaft component 2, guarantee the safety of medical equipment 100 in use process.

[0030] In the embodiments of the present application, the at least one cantilever assembly 1 is sleeved on the outer periphery of the main shaft assembly 2 and is electrically connected with the main shaft assembly 2, that is, the main shaft assembly 2 and the cantilever assembly 1 are connected through wires or cables. The one-way rotation of the cantilever assembly 1 around the main shaft assembly 2 is limited, that is, when the cantilever assembly 1 rotates around the main shaft assembly 2, the limiting assembly 3 is located on the rotation track of the cantilever assembly 1, which can prevent the cantilever assembly 1 from rotating in one direction, that is, the rotation angle of the cantilever assembly 1 in one direction is less than 360 degrees. In this way, the wires or cables used to connect the main shaft assembly 2 and the cantilever assembly 1 can be prevented from being continuously wound, pulled, or even broken during the one-way rotation of the cantilever assembly 1.

[0031] In some embodiments, referring to Figure 1 , a part of the limiting assembly 3 can be parallel to the main shaft assembly 2 in the first direction, wherein the first direction is the extension direction of the main shaft assembly 2. Since the cantilever assembly 1 can rotate around the main shaft assembly 2, and a part of the limiting assembly 3 can be parallel to the extension direction of the main shaft assembly 2, the extension direction of the main shaft assembly 2 is the length direction thereof. This part of the limiting assembly 3 can be located at least partially on the track of the cantilever assembly 1 rotating around the main shaft assembly 2, thereby preventing the cantilever assembly 1 from continuously rotating in one direction. That is, the cantilever assembly 1 can be blocked by a part of the limiting assembly 3 during rotation. When the cantilever assembly 1 is blocked by the limiting assembly 3, the cantilever assembly 1 can be limited to prevent it from continuing to rotate in the original direction. After the cantilever assembly 1 is blocked by the limiting assembly 3, it cannot continue to rotate in the original rotation direction and can rotate in the opposite direction of the original rotation direction. When the cantilever assembly 1 rotates in the opposite direction of the original rotation direction to interfere with the limiting assembly 3 again, the rotation can be stopped again. For example, the cantilever assembly 1 can rotate clockwise to interfere with the limiting assembly 3 and stop rotating; then it can rotate counterclockwise to interfere with the limiting assembly 3 and stop rotating; the cantilever assembly 1 can repeatedly rotate within the above rotation range.

[0032] In other embodiments, a plurality of limiting assemblies 3 can also be provided on the main shaft assembly 2 to limit the rotation angle of the cantilever assembly 1 around the main shaft assembly 2. For example, one limiting assembly 3 can be provided on each of the opposite sides of the main shaft assembly 2, so that the rotation angle of the cantilever assembly 1 is 180 degrees. Alternatively, one limiting assembly 3 can be provided at the 0-degree position and another limiting assembly 3 can be provided at the 90-degree position on the outer periphery of the main shaft assembly 2, so that the cantilever assembly 1 can rotate 90 degrees clockwise and 270 degrees counterclockwise.

[0033] In some embodiments, referring to Figure 1The limiting assembly 3 comprises a main body 31 and an extension 32. The main body 31 is connected with the main shaft assembly 2 and is arranged along the extension direction of the main shaft assembly 2. The extension 32 is connected with the main body 31 and is arranged along the second direction. The extension 32 is configured to limit the one-way rotation of the cantilever assembly 1 around the main shaft assembly 2. The second direction is perpendicular to the first direction, i.e. parallel to the radial direction of the main shaft assembly 2. The cantilever assembly 1 can be blocked by the extension 32 during rotation. When the cantilever assembly 1 is blocked by the extension 32, the cantilever assembly 1 can be limited to prevent further rotation in the original direction. After the cantilever assembly 1 interferes with the extension 32, it cannot continue to rotate in the original rotation direction and can rotate in the opposite direction of the original rotation direction. When the cantilever assembly 1 rotates in the opposite direction of the original rotation direction and interferes with the extension 32 again, the rotation can be stopped again.

[0034] In some embodiments, referring to Figure 1 , the fixed end of the extension 32 is connected with the main body 31, and the free end extends from the main body 31 to the cantilever assembly 1 along the length direction of the main shaft assembly 2. Since the cantilever assembly 1 can rotate around the main shaft assembly 2, and the extension 32 can extend towards the cantilever assembly 1, and the extension 32 overlaps the cantilever assembly 1 in the height direction, i.e. the cantilever assembly 1 can interfere with the extension 32 during rotation. When the cantilever assembly 1 interferes with the extension 32, the cantilever assembly 1 can be limited to prevent further rotation in the original direction.

[0035] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the limiting assembly 3 comprises a first limiting part 33 and a second limiting part 34. The first limiting part 33 is connected with the main shaft assembly 2, and the second limiting part 34 is connected with the cantilever assembly 1. The second limiting part is configured to rotate with the cantilever assembly 1. The first limiting part is configured to limit the one-way rotation of the second limiting part around the main shaft assembly 2. The second limiting part 34 can interfere with the first limiting part 33 when rotating with the cantilever assembly 1 around the main shaft assembly 2, thereby stopping the further rotation of the second limiting part 34, i.e. stopping the further rotation of the cantilever assembly 1.

[0036] In some embodiments, referring to Figure 3 and Figure 4The first limiting part 33 comprises a first limiting block 331, a second limiting block 332 and a fastener 333. The first limiting block 331 and the second limiting block 332 are arranged around the outer periphery of the main shaft assembly 2 and are connected to the main shaft assembly 2 through the fastener 333. The first limiting part 33 can be detachably connected to the main shaft assembly 2 through the fastener 333, that is, the first limiting block 331 and the second limiting block 332 are fastened to the outer periphery of the main shaft assembly 2 through the fastener 333. Thus, when the second limiting part 34 rotates with the cantilever assembly 1 around the main shaft assembly 2, the first limiting part 33 fastened to the outer periphery of the main shaft assembly 2 can stop the second limiting part 34 and prevent the second limiting part 34 from continuously rotating in one direction.

[0037] In some embodiments, referring to Figure 3 and Figure 4 The first limiting block 331 and the second limiting block 332 are both arc-shaped. One end of the first limiting block 331 is provided with a groove 3311, and the other end is provided with a first through hole 3312. One end of the second limiting block 332 is provided with a protrusion 3321 corresponding to the position of the groove 3311, and the other end is provided with a second through hole 3322. When the first limiting block 331 and the second limiting block 332 are matched along the outer periphery of the main shaft assembly 2, one end of the first limiting block 331 and the second limiting block 332 is connected by inserting the protrusion 3321 into the groove 3311, and the other end is fastened by the fastener 333 passing through the first through hole 3312 and the second through hole 3322 in sequence. Thus, when the second limiting part 34 rotates with the cantilever assembly 1 around the main shaft assembly 2, the first limiting part 33 fastened to the outer periphery of the main shaft assembly 2 can stop the second limiting part 34 and prevent the second limiting part 34 from continuously rotating in one direction.

[0038] In some embodiments, referring to Figure 3 and Figure 4 The second limiting part 34 is provided with at least one third through hole 341, and the cantilever assembly 1 is provided with a connecting hole 111. The second limiting part 34 comprises a fastener 333, and the fastener 333 fixes the second limiting part 34 to the cantilever assembly 1 by passing through the third through hole 341 and the connecting hole 111 in sequence. Thus, when the second limiting part 34 rotates with the cantilever assembly 1 around the main shaft assembly 2, the second limiting part 34 can be stopped by interfering with the first limiting part 33.

[0039] In some embodiments, referring to Figure 3 and Figure 4 The cantilever assembly 1 comprises a bearing 11 and an arm body 12. The bearing 11 is sleeved on the outer periphery of the main shaft assembly 2 and rotates along the main shaft assembly 2. A wall body is connected to the bearing 11 and rotates with the bearing 11.

[0040] In some embodiments, referring to Figure 3 and Figure 4The main shaft assembly 2 comprises a main shaft and at least one support platform 21; the at least one support platform 21 is sleeved on the main shaft, and the support platform 21 is used for supporting the bearing 11 and limiting the bearing 11 from moving along the length direction of the main shaft. Thus, the cantilever assembly 1 is relatively stable during rotation and does not shake.

[0041] The above is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
