Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1-3, an embodiment of the present invention discloses a rotating mechanism, which includes a mounting member 100 and a rotating sleeve 200. The rotation mechanism may be a mounting structure of the mounted apparatus 600 such as a camera. More specifically, the mounted device 600 may be fixedly mounted on the rotating sleeve 200, such that the mounted device 600 mounted on the rotating mechanism can rotate relative to a mounting base, such as a roof, a cavity, the mounting arm 500, or a mounting bracket. Alternatively, as shown in fig. 3, a rotating mechanism may be installed on the installation arm 500, so that the camera or the like installed device 600 can be hung at a preset height, and by means of the rotating mechanism, the viewing range of the camera or the like installed device 600 is expanded, and the viewing range of the camera is increased.

Wherein, the mounting member 100 comprises a mounting body 110 and a first limit boss 120, and the first limit boss 120 is convexly arranged at the side of the mounting body 110. Specifically, the side of the mounting body 110 is a surface between two opposite ends of the middle phase of the mounting body 110; or, the first limit projection 120 is coupled to the outer wall surface of the mounting body 110. Specifically, the first limit boss 120 may be integrally formed with the mounting body 110 to improve the connection reliability therebetween. The mounting body 110 may have a prismatic structure or a cylindrical structure. The mounting body 110 may have a solid structure or a hollow structure. The dimensions of the mounting body 110 and the first limit projection 120 may be determined according to actual requirements, and are not limited herein.

The rotating sleeve 200 includes a sleeve body 210 and a second limiting protrusion 220, the second limiting protrusion 220 is protruded from an inner wall of the sleeve body 210, the sleeve body 210 may be a sleeve and has a hollow structure, and the inner surface and the outer surface of the sleeve body 210 may have the same or different shapes. Optionally, the inner surface of the sleeve body 210 is cylindrical, and correspondingly, the outer edge of the first limiting boss 120 away from the mounting body 110 may also be arc-shaped or circular structure, so that the rotation between the sleeve body 210 and the first limiting boss 120 is smoother, and the mounting body 110 and the sleeve body 210 are more tightly fitted. Of course, in the case that the inner surface of the sleeve body 210 is of a prism-like structure, and the outer edge of the first limiting projection 120 away from the mounting body 110 includes a planar structure, the relative rotation between the rotating sleeve 200 and the mounting member 100 can also be ensured by designing the sizes of the two.

The second limiting boss 220 has a dodging hole, that is, the second limiting boss 220 in the sleeve body 210 does not completely block the cavity of the sleeve body 210, the dodging hole is formed by enabling the second limiting boss 220, the two ends of the sleeve body 210, which are opposite to each other, can be communicated with each other, and therefore the sleeve body 210 can be assembled with the mounting part 100.

In the assembling process of the rotating mechanism, one end of the mounting body 110 can extend into the sleeve body 210 and pass through the avoiding hole to extend out of the sleeve body 210, that is, the size of the mounting body 110 is smaller than that of the avoiding hole in the corresponding direction, so that the mounting body 110 can pass through the avoiding hole. By performing the above-described assembling operation, the mounting body 110 and the sleeve body 210 can be assembled together; also, the mounting body 110 and the sheath body 210 may be rotationally engaged, that is, the mounting body 110 and the sheath body 210 can be relatively rotated, so that the mounted apparatus 600 mounted on the rotating sheath 200 can be rotated relative to the mounting base.

Meanwhile, in order to prevent the installation body 110 and the sleeve body 210 from being separated from each other, the first limiting boss 120 is limited to the second limiting boss 220 along the extending direction of the installation body 110, so that after the installation body 110 extends into the sleeve body 210 through one end of the sleeve body 210, the installation body 110 can be limited through the first limiting boss 120, the installation body 110 is prevented from penetrating out of the sleeve body 210 in an uncontrolled manner, the rotating sleeve 200 can be reliably hung on the installation body 110, and the gravity of the rotating sleeve 200 (and the installed device 600 installed on the rotating sleeve 200) can act on the installation part 100.

Of course, as mentioned above, the rotating mechanism may also be interconnected with other devices during use of the rotating mechanism. Specifically, the end of the mounting member 100 protruding from the rotary sleeve 200 may be coupled to a mounting base such as the mounting arm 500 or a mounting bracket, which may prevent the rotary sleeve 200 and the mounting member 100 from being separated from each other; in addition, the rotating sleeve 200 also needs to be connected with the mounted device 600, and the mounting piece 100 can be prevented from being separated from the rotating sleeve 200 under the blocking action of the mounted device 600.

More specifically, there are various ways of connection between the mounting member 100 and the mounting base, and between the rotating sleeve 200 and the mounted device 600. Alternatively, the mounting member 100 can be stably mounted on the mounting base by means of clamping or the like, and the mounted device 600 can be reliably connected with the rotating sleeve 200. Optionally, through threaded connectors such as bolts or screws, the connection difficulty between the mounting piece 100 and the mounting base and between the rotating sleeve 200 and the mounted device 600 can be reduced, the reliability of the connection relationship can be guaranteed to be high, and the mounting device is convenient to detach. Alternatively, the mounting member 100 and the rotating sleeve 200 may be provided with a threaded hole 211, and the threaded hole 211 may be engaged with the threaded connector 430.

The application provides a slewing mechanism, it includes installed part 100 and rotating sleeve 200, and the one end of installation body 110 can stretch into in the cover body 210 of rotating the piece in the installed part 100, and stretches out from the one end of cover body 210 to make installation body 110 can with installation basis interconnect such as installation arm 500 or mounting bracket, install slewing mechanism to the installation on the basis. Meanwhile, the first limit boss 120 in the mounting part 100 can be in limit fit with the second limit boss 220 in the sleeve body 210, so that the mounting body 110 and the sleeve body 210 which extend into one end of the sleeve body 210 are prevented from being separated from each other, and the rotating sleeve 200 can be stably connected to the mounting part 100 through the second limit boss 220. The mounting body 110 and the sleeve body 210 can rotate relative to each other, so that the mounted device 600 mounted on the rotating sleeve 200 can rotate relative to the mounting base, thereby enlarging the coverage of the mounted device 600. In conclusion, the rotating mechanism can provide a steering function for the mounted device 600, and the rotating mechanism is simple in structure, convenient to assemble and relatively low in cost.

As described above, there are various types of installation bases, and this embodiment specifically exemplifies an application scenario of the above-described rotating mechanism. In detail, the rotating mechanism can be installed on the medical equipment, in the process of diagnosing and treating diseases, a doctor is usually required to be assisted by the aid of the shooting equipment to know the illness state of a patient, the shooting equipment can be specifically installed at the tail end of a suspension arm of the medical equipment through the rotating mechanism, in order to prevent the suspension arm and other equipment from interfering with the diagnosis and treatment process, the position of the suspension arm is generally required to be changed according to the diagnosis and treatment process, in this case, the shooting equipment such as a camera and the like can be installed on the suspension arm through the rotating mechanism to adjust the orientation of the shooting equipment through the rotating mechanism, and further, no matter what position or what state the suspension arm is, the shooting equipment can be ensured to be oriented to the treatment table, so that the shooting equipment can always and normally acquire the view at the treatment table.

In order to ensure that the first limiting boss 120 and the second limiting boss 220 can limit each other in the axial direction of the avoiding hole, the sum of the angles of the first limiting boss 120 and the second limiting boss 220 extending in the axial direction around the avoiding hole can be larger than 360 degrees, in this case, no matter how the first limiting boss 120 and the second limiting boss 220 rotate relatively, partial structures in the first limiting boss 120 and the second limiting boss 220 can be guaranteed to limit each other in the axial direction of the avoiding hole, and the rotating sleeve 200 can be hung on the mounting member 100.

In another embodiment of the present application, at least one of the first limiting projection 120 and the second limiting projection 220 is a closed circular ring-shaped structural member, in which case, on the one hand, the stability of the limiting fit relationship between the first limiting projection 120 and the second limiting projection 220 can be improved, and on the other hand, the rotational fit relationship between the first limiting projection 120 and the sleeve body 210, and/or between the second limiting projection 220 and the mounting body 110 can be more stable. Optionally, the first limit boss 120 and the second limit boss 220 may be both closed circular ring-shaped structural members, and correspondingly, the side surface of the mounting body 110 and the inner surface of the sleeve body 210 may be both cylindrical structures, so as to further improve the stability of the rotation fit relationship and the limit relationship between the mounting member 100 and the rotating sleeve 200.

Optionally, along the extending direction of the mounting body 110, that is, the axial direction of the avoiding hole, the first limiting boss 120 may be located in the middle of the mounting body 110, that is, a certain distance is provided between the two opposite ends of the first limiting boss 120 and the mounting body 110, in this case, when the first limiting boss 120 extends into the sleeve body 210 along with the mounting body 110 and is in limiting fit with the second limiting boss 220, besides the first limiting boss 120, a part of the mounting body 110 may also be accommodated in the sleeve body 210.

In another embodiment of the present application, optionally, the first limit projection 120 is disposed flush with one end of the mounting body 110, that is, the first limit projection 120 is disposed at one end of the mounting body 110. In this case, when the mounting member 100 and the rotating sleeve 200 are assembled, along with the fact that the end of the mounting body 110, which is far away from the first limiting boss 120, extends into the sleeve body 210, when the first limiting boss 120 and the second limiting boss 220 are limited, the area of the first limiting boss 120, which is far away from the second limiting boss 220, in the sleeve body 210 can be made to be free, so that the area can be used as a space for accommodating the mounted device 600, and further, the mounted device 600 can be mounted outside the rotating sleeve 200 or inside the rotating sleeve 200, the mounting manner of the mounted device 600 is enlarged, and the usability of the rotating mechanism is improved. Moreover, in the case of the above technical solution, more parts of the mounting body 110 may protrude from the sheath body 210, so as to increase the size of the connection portion between the mounting body 110 and the mounting base, in other words, in the case of the above technical solution, even if the overall size of the mounting body 110 is reduced, the size of the part of the mounting body 110 protruding from the sheath body 210 can be ensured to meet the mounting requirement.

Correspondingly, the second limiting boss 220 can be arranged in parallel with one end of the sleeve body 210, and compared with the scheme that the second limiting boss 220 is arranged between the two opposite ends of the sleeve body 210, by adopting the technical scheme, the accommodating space in the sleeve body 210 can be enlarged, and even if the size of the installation body 110 is relatively small, the size of the part, extending out of the sleeve body 210, of the installation body 110 can be ensured to meet the installation requirement.

Optionally, the second limiting boss 220 and the first end of the sleeve body 210 are axially spaced apart from each other along the avoiding hole, as described above, the first limiting boss 120 may extend into the sleeve body 210 along with the mounting body 110, and the first limiting boss 120 may be limited at the second limiting boss 220. The first limiting boss 120 may extend into the sleeve body 210 from the first end of the sleeve body 210, and the first end and the first limiting boss 120 may be axially spaced apart from each other along the avoiding hole. In the above situation, an accommodating space can be formed in the sheath body 210 on the side of the first limit boss 120 away from the second limit boss 220, so that a part of the mounted device 600 can extend into the sheath body 210 and be located in the accommodating space, and the mounted device 600 is fixedly connected with the sheath body 210. Under the condition of adopting the technical scheme, the first limiting boss 120 can be arranged between the second limiting boss 220 and the mounted equipment 600 along the axial limiting of the avoiding hole, so that a more stable and reliable hoisting relation is formed between the mounting part 100 and the rotating sleeve 200. When the distance between the second limit boss 220 and the mounted device 600 in the axial direction of the avoiding hole is slightly larger than the dimension of the first limit boss 120 in the aforementioned direction, the mounting member 100 and the rotating sleeve 200 can be basically kept fixed in the axial direction of the avoiding hole, so that the connection reliability between the mounting member 100 and the rotating sleeve 200 is further improved.

Optionally, the mounting member 100 and the rotating sleeve 200 are both metal structural members to improve the structural strength of the mounting member 100 and the rotating sleeve 200, thereby improving the load-bearing capacity of the rotating mechanism. In the above case, the rotating mechanism may further include a gap maintaining member 310, and at least a portion of the gap maintaining member 310 is interposed between the mounting body 110 and the rotating sleeve 200, that is, the gap maintaining member 310 is disposed between the mounting body 110 and the rotating sleeve 200.

Furthermore, since the size of the avoiding hole needs to be larger than the size of the mounting body 110 in the corresponding direction, in order to prevent the mounting body 110 and the rotating sleeve 200 from generating noise due to mutual friction during the relative rotation process, optionally, during the process of assembling the rotating mechanism, the mounting body 110 may be attached to one side of the gap maintaining member 310, and the rotating sleeve 200 may be attached to the other side of the gap maintaining member 310, so that the inner walls of the mounting body 110 and the avoiding hole maintain a preset gap. That is, by providing the gap maintaining member 310, a certain interval may be always maintained between the mounting body 110 and the rotating sleeve 200 to prevent the rotating sleeve 200 and the mounting body 110 from directly contacting with each other by the gap maintaining member 310. Specifically, the size of the gap that is always maintained between the mounting body 110 and the rotating sleeve 200 may be determined according to actual requirements, and the size of the gap may be changed by controlling the size of the gap maintaining member 310 in the direction perpendicular to the axial direction of the avoiding hole.

By making the gap maintaining member 310 a non-metal structure, it is possible to prevent the installation body 110 and the rotation sleeve 200 from rubbing against each other to generate a harsh abnormal sound, thereby reducing the operating noise of the rotation mechanism. In addition, under the action of the gap maintaining member 310, the clamping phenomenon between the rotating sleeve 200 and the mounting body 110 can be prevented, and the normal rotating connection state between the rotating sleeve 200 and the mounting body 110 can be stably maintained.

Specifically, the gap retaining member 310 may be an open ring structure, such as a semi-ring structure, and the gap retaining member 310 may be sleeved outside the mounting body 110 and embedded inside the sleeve body 210. Alternatively, the gap maintaining member 310 can be fixed on the side surface of the mounting body 110 by means of bonding or the like, so that during the operation of the rotating mechanism, the gap maintaining member 310 can be prevented from moving relative to the mounting body 110 (and the sleeve body 210) along the axial direction of the avoiding hole, and thus the gap maintaining member 310 can be always clamped between the rotating sleeve 200 and the mounting body 110.

More specifically, the gap maintaining member 310 may be made of a flexible material such as rubber, or the gap maintaining member 310 may also be made of a hard plastic, so as to prevent the gap maintaining member 310 from being elastically deformed, and the rotating sleeve 200 and the mounting body 110 may press the gap maintaining member 310, so that the rotating sleeve 200 and the mounting body 110 relatively move in a direction perpendicular to the axial direction of the avoiding hole, thereby ensuring that the first limiting boss 120 and the second limiting boss 220 have high limiting reliability. More specifically, the gap maintaining member 310 may be made of polyoxymethylene resin, which has excellent comprehensive properties, good physical, mechanical and chemical properties, high hardness, and high friction resistance, so as to ensure a long service life of the gap maintaining member 310, reduce the friction between the rotating sleeve 200 and the mounting body 110, and prolong the service life of the rotating mechanism.

Optionally, the second limit projection 220 is provided with a receiving groove in which at least a portion of the gap maintaining member 310 is received. Specifically, the receiving groove communicates with the avoiding hole to ensure that at least a part of the gap maintaining member 310 received in the receiving groove can contact the mounting body 110 penetrating the avoiding hole; the gap maintaining member 310 is also in contact with the rotating sleeve 200, so that at least a part of the gap maintaining member 310 can be interposed between the rotating sleeve 200 and the mounting body 110.

In order to prevent the gap maintaining member 310 from moving on the mounting body 110 in the axial direction of the avoiding hole, the gap maintaining member 310 may be an open annular member, and a stopper member may be provided for the gap maintaining member 310. In the process of assembling the rotating mechanism, the gap retaining member 310 may be sleeved on the mounting body 110 from one side of the mounting body 110 by elastically deforming the gap retaining member 310 to a certain extent, and the limiting structural member is connected to the predetermined position of the mounting body 110, and the gap retaining member 310 may also be limited between the limiting structural member and the second limiting boss, thereby ensuring that the gap retaining member 310 can be always clamped between the rotating sleeve 200 and the mounting member 100.

In another embodiment of the present application, optionally, the gap maintaining member 310 is a closed annular structural member, in which case the gap maintaining member 310 may be installed outside the installation body 110 in a sleeved manner, in which case an inner sidewall of the gap maintaining member 310 is attached to the installation body 110, an outer sidewall of the gap maintaining member 310 is attached to the rotating sleeve 200, and at least a portion of the gap maintaining member 310 is extended into the receiving groove, so that at least a portion of the gap maintaining member 310 can be interposed between the installation body 110 and the rotating sleeve 200. Under the condition, the accommodating groove can be arranged in the middle of the second limit sinking platform along the axial direction of the avoiding hole, namely, the accommodating groove is provided with a part of the second limit sinking platform along the two sides of the axial direction of the avoiding hole, which are opposite to each other. In the process of assembling the rotating mechanism, the gap holder 310 may be installed into the accommodating groove, and then the mounting member 100 is inserted into the rotating sleeve 200, so that the first and second limit bosses 120 and 220 are limited to each other.

As described above, the gap maintaining member 310 may be a structural member made of a hard material, in which case, the closed annular gap maintaining member 310 is not easy to be installed into the receiving groove by the installation method provided by the above-mentioned embodiment. Alternatively, the receiving groove is located at an end of the second limit projection 220 facing away from the first limit projection 120 in the axial direction of the avoiding hole, in which case the gap maintaining member 310 may be directly mounted into the receiving groove and the structural integrity of the gap maintaining member 310 may be ensured. On this basis, the rotating mechanism provided in the embodiment of the present application may further include a limiting member 330, the limiting member 330 is detachably and fixedly connected to the mounting body 110, and after the gap retaining member 310 is mounted on the rotating sleeve 200 or the mounting body 110, the limiting member 330 is fixedly connected to the mounting body 110, so that the gap retaining member 310 can be limited, and thus the limiting member 330 can only move in a predetermined region, and at least a portion of the gap retaining member 310 can be always clamped between the rotating sleeve 200 and the mounting member 100.

Specifically, the limiting member 330 may be a limiting nail or a limiting protrusion, and the specific structure of the limiting member 330 is not limited herein. The limiting member 330 may be detachably and fixedly connected to the mounting body 110 by means of clamping, inserting, or connecting with a threaded connector.

Further, the rotating mechanism may further include a separation preventing member 320, the gap retaining member 310 is disposed around one end of the separation preventing member 320, that is, the diameter of the gap retaining member 310 is larger than the diameter of the end of the separation preventing member 320 connected to the gap retaining member 310, as described above, at least a portion of the gap retaining member 310 may be sandwiched between the limiting member 330 and the rotating sleeve 200; meanwhile, the anti-slip member 320 extends between the limiting member 330 and the mounting body 110, in this case, the anti-slip member 320 may provide a certain limiting effect for the gap maintaining member 310, so as to further prevent the gap maintaining member 310 from being separated from between the limiting member 330 and the rotating sleeve 200 due to the rotation relative to the mounting body 110.

Specifically, the limiting member 330 may be a long strip-shaped structural member, a certain gap may be provided between the limiting member 330 and the mounting body 110, and the limiting member 330 may be connected to the mounting body 110 through a plurality of connecting members, so as to ensure that the limiting member 330 can provide a required accommodating space for the anti-falling member 320.

As described above, the gap maintaining member 310 may be a closed circular ring-shaped structural member, and based on this, in another embodiment of the present application, optionally, the limiting member 330 and the anti-falling member 320 are both closed circular ring-shaped structural members, which may further enhance the limiting effect of the anti-falling member 320 on the gap maintaining member 310, so that the gap maintaining member 310 is more stably clamped between the rotating sleeve 200 and the mounting body 110. Optionally, a through hole or a threaded hole may be formed in the limiting member 330, so that the limiting member 330 sleeved outside the mounting member 100 may be detachably and fixedly connected to the mounting body 110 through a threaded connector such as a bolt, so as to improve the connection reliability between the limiting member 330 and the mounting body 110, and by making the size of the inner wall of the limiting member 330 larger than the size of the side surface of the mounting body 110 in the corresponding direction, that is, making the inner diameter of the limiting member 330 larger than the outer diameter of the mounting body 110, it may be ensured that an accommodation gap may be formed between the limiting member 330 and the mounting body 110, and the anti-falling member 320 may be mounted in the accommodation gap and clamped between the limiting member 330 and the mounting body 110. In addition, in the above embodiment, the entire rotating mechanism can be mounted on the mounting base through the stopper 330.

As described above, the mounted device 600 is mounted on the rotating sleeve 200, and may be connected outside the rotating sleeve 200 or inside the rotating sleeve 200, and the mounting body 110 may have a solid structure or a hollow structure. Optionally, the installation body 110 and the limiting member 330 are both provided with threading holes, that is, the installation body 110 and the limiting member 330 are both hollow structures, and the cable of the installed device 600 fixed on the rotating sleeve 200 can pass through the threading holes, so as to provide a binding effect for the cable by means of the installation member 100 and the limiting member 330, and prevent the cable from being entangled with other objects.

Based on the above situation, optionally, one of the limiting member 330 and the rotating sleeve 200 is provided with a first positioning member 410, the other one is provided with a second positioning member 420, and the first positioning member 410 and the second positioning member 420 are distributed along the circumferential direction of the rotating sleeve 200. Based on the above embodiment, after the rotating sleeve 200 rotates by a certain angle relative to the limiting member 330 in the first direction, the first positioning member 410 and the second positioning member 420 can limit the rotating sleeve 200 to continue to rotate relative to the limiting member 330 in the first direction, so that the rotating sleeve 200 can only rotate relative to the limiting member 330 in the opposite direction of the first direction; correspondingly, after the rotating sleeve 200 rotates by a certain angle relative to the limiting member 330 in the opposite direction of the first direction, the first positioning member 410 and the second positioning member 420 still contact and limit each other. That is, by providing the first positioning member 410 and the second positioning member 420, the rotating sleeve 200 and the mounting member 100 can only rotate reciprocally within a predetermined angle range, thereby preventing the cable threaded through the cable hole from twisting due to the fact that the rotating sleeve 200 and the mounting member 100 can rotate relatively without limitation.

In the case where the sizes of the first and second positioning members 410 and 420 are not determined, the maximum angle at which the relative rotation between the rotating sleeve 200 and the mounting member 100 is possible is different. Alternatively, the aforementioned angular range may be α, and 0 ° ≦ α < 360 ° may be provided, and more specifically, the maximum angle that enables relative rotation between the rotating sleeve 200 and the mounting member 100 may be 355 °.
