Description

[0001] This application is based on and claims priority to Chinese Patent Application No. 202211062725.4, filed on August 31, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of medical device technology, and in particular to an arm support device. Background Technology

[0003] An arm support device is an accessory for the operating table, primarily used to support the arm during surgery. In related technologies, the arm support device's hand rest needs to rotate 180° horizontally and lock relative to the connector. Therefore, the arm support device typically includes components such as a rod assembly to adjust the rotation angle of the hand rest.

[0004] However, in related technologies, the placement of the pole components is not ideal, making them prone to accumulating dirt, which greatly hinders the cleaning and disinfection of the arm support device. Summary of the Invention

[0005] In view of this, the embodiments of this application aim to provide an arm support device that is easy to clean and disinfect.

[0006] To achieve the above objectives, one embodiment of this application provides an arm support device, comprising:

[0007] Connection components;

[0008] A support component is rotatably connected to the connecting component, and the rotation angle is adjustable;

[0009] An operating component, which cooperates with the connecting component to achieve and / or release the locking of the rotation angle between the support component and the connecting component;

[0010] The operating component includes an operating body that can move relative to the support component. The rotation angle between the connecting component and the support component is locked, and the operating body is housed inside the support component.

[0011] Another embodiment of this application provides an arm support device, including:

[0012] Connection components;

[0013] A support component is rotatably connected to the connecting component, and the rotation angle is adjustable;

[0014] An operating component, which cooperates with the connecting component to achieve and / or release the locking of the rotation angle between the support component and the connecting component;

[0015] The operating component includes an operating body that can move relative to the support component. The operating body includes an operating part and a gripping part disposed at one end of the operating part. The operating part includes a first segment and a second segment. The end of the second segment opposite to the first segment is connected to the gripping part. The length of the first segment is greater than the length of the second segment. The first segment is hidden inside the support component.

[0016] Another embodiment of this application provides an arm support device for connection to an operating table, including: a connecting component;

[0017] A support component is rotatably connected to the connecting component, and the rotation angle is adjustable;

[0018] A locking component that cooperates with the connecting component to achieve and / or release the locking between the support component and the connecting component;

[0019] The locking component includes a locking member that is movable relative to the support component, and is in a locked state between the connecting component and the support component, wherein the locking member is housed inside the support component.

[0020] This application provides an arm support device, which includes a connecting component, a supporting component, and an operating component. The supporting component and the connecting component are rotatably connected, and the rotation angle is adjustable. The operating component cooperates with the connecting component to lock and / or release the rotation angle between the supporting component and the connecting component. When the rotation angle between the connecting component and the supporting component is locked, the operating body of the operating component is housed inside the supporting component. That is, when the rotation angle between the connecting component and the supporting component is locked, the operating body is not located on the outer surface of the supporting component. Therefore, the operating body is less prone to dirt accumulation. During cleaning and disinfection, generally only the outer surface of the arm support device needs to be cleaned and disinfected, without needing to clean and disinfect the operating body. This greatly improves the convenience of cleaning and disinfecting the arm support device. Attached Figure Description

Detailed Implementation

[0040] In the description of the embodiments of this application, it should be noted that the terms "length direction," "width direction," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0041] One embodiment of this application (first embodiment) provides an arm support device 100. Please refer to [link to relevant documentation]. Figures 1 to 7 The arm support device 100 includes a connection component 10, a support component 20, and an operation component 30.

[0042] The connecting component 10 is used to mount the arm support device 100 at a position such as the side rail 200 of the operating table.

[0043] Support component 20 is used to support the arm.

[0044] The support component 20 is rotatably connected to the connecting component 10, and the rotation angle is adjustable. That is, the support component 20 can rotate relative to the connecting component 10, and the rotation angle between the support component 20 and the connecting component 10 can also be adjusted as needed.

[0045] The operating component 30 cooperates with the connecting component 10 to lock and / or release the rotation angle between the support component 20 and the connecting component 10. That is, the operating component 30 can be used only to lock the rotation angle between the support component 20 and the connecting component 10, or only to release the rotation angle between the support component 20 and the connecting component 10, or it can be used to both lock and release the rotation angle between the support component 20 and the connecting component 10.

[0046] Please continue reading. Figures 2 to 5 The operating component 30 includes an operating body 31 that can move relative to the support component 20. When the rotation angle between the connecting component 10 and the support component 20 is locked, the operating body 31 is housed inside the support component 20.

[0047] Figure 4 and Figure 5 The operating component 30 shown is a rigid component, specifically, Figure 4 and Figure 5 The operating component 30 shown is a lever assembly, the operating body 31 is a lever, and the operating part 311 of the operating body 31 is a lever.

[0048] In other embodiments, please refer to Figure 17 The operating component 30 can also be a combination of rigid and flexible components; that is, the operating body 31 can be a combination of flexible and rigid bodies, for example, in... Figure 17 In the operation body 31, the operation part 311 is a flexible body, which can be a rope such as a brake rope, or a strip with a certain width, while the grip part 312 is a rigid body.

[0049] In some other embodiments, the operating component 30 may also be a flexible component, wherein the operating body 31 of the flexible component is a flexible body.

[0050] It should be noted that the operating body 31 is housed inside the support component 20, as long as it does not exceed the overall outline of the support component 20. The operating body 31 may be completely invisible to the outside, or it may be partially visible through the holes opened on the support component 20.

[0051] In other words, at least when the rotation angle between the connecting component 10 and the supporting component 20 is locked, the operating body 31 is not located on the outer surface of the supporting component 20. The operating body 31 can be completely or partially covered by the supporting component 20, which not only makes it less prone to dirt but also improves its appearance.

[0052] In related technologies, the operating body is generally set on the outer surface of the arm support plate, which means that the operating body is completely exposed. Therefore, dirt is easily generated on the operating body, which brings great inconvenience to the cleaning and disinfection of the arm support device.

[0053] Please see Figure 2 and Figure 5 The support component 20 has a receiving space 21 and an opening 22 communicating with the receiving space 21. The operating part 311 and the grip part 312 are disposed in the receiving space 21, with the grip part 312 positioned opposite the opening 22. That is, the grip part 312 is exposed to the external view through the opening 22. When the user needs to apply force to the operating body 31, he / she only needs to put his / her hand into the receiving space 21 through the opening 22 to grasp the grip part 312, making the operation simple and convenient.

[0054] An openable and closable cover can also be provided at the opening 22. When the grip 312 is not in use, the cover can be closed to seal the opening 22. When the grip 312 needs to be used, the cover can be opened.

[0055] Please see Figure 5 The support assembly 20 includes a support plate 23, and the accommodating space 21 includes an accommodating groove 211 disposed on the support plate 23. The groove opening of the accommodating groove 211 is opened on one side surface of the support plate 23, and the operating part 311 is inserted into the accommodating groove 211 from the groove opening. That is to say, the operating part 311 can be accommodated inside the support plate 23.

[0056] Figures 1 to 3 The receiving groove 211 and the connecting assembly 10 shown are respectively disposed on opposite sides of the support plate 23. That is, the operating part 311 is inserted into the receiving groove 211 from the side of the support plate 23 away from the connecting assembly 10. In another embodiment, please refer to... Figures 8 to 11 The receiving groove 211 can also be provided on the same side of the support plate 23 as the connecting component 10. That is, the operating part 311 can be inserted into the receiving groove 211 from the side of the support plate 23 where the connecting component 10 is provided.

[0057] Please see Figure 5 The accommodating space 21 may also be provided with an accommodating hole 212. The accommodating hole 212 is provided on the support plate 23 and is open to the outside of the support component 20. The area of ​​the accommodating hole 212 that is open to the outside of the support component 20 forms an opening 22. The gripping part 312 is provided in the accommodating hole 212 and is provided relative to the opening 22.

[0058] In other words, the support plate 23 can also be provided with a receiving hole 212 for accommodating the gripping part 312, and the receiving hole 212 has an opening 22.

[0059] In this embodiment, the receiving hole 212 and the receiving groove 211 are interconnected, and the receiving hole 212 and the receiving groove 211 together form a receiving space for placing the operating body 31.

[0060] Please see Figures 3 to 5 The support component 20 also includes a shielding member 24, which covers the opening of the receiving groove 211. In other words, the opening can be blocked by the shielding member 24 to enclose the operating part 311 in the receiving groove 211. The shielding member 24 can be any part that can cover the opening and be fixed to both sides of the opening. In this embodiment, the shielding member 24 is a Velcro.

[0061] Please see Figures 1 to 6 The support assembly 20 also includes a support pad 25, which is disposed on the side of the support plate 23 with a slot, and the shield 24 is located between the support pad 25 and the support plate 23.

[0062] The support pad 25 is designed to come into contact with a person's arm, meaning the arm rests against the support pad 25. The support pad 25 is positioned on the side of the support plate 23 with the slot, effectively shielding the slot and the cover 24. This makes the slot and cover 24 invisible from the outside of the arm support device 100, thus improving its appearance and facilitating cleaning and disinfection. Additionally, the cover 24 provides support to the support pad 25, preventing any portion of it from being pressed into the receiving groove 211 when the arm is resting on it.

[0063] In some embodiments, the shielding member 24 may not be provided. For example, the support pad 25 may be directly provided on the side of the support plate 23 with the slot, so as to shield the slot of the receiving groove 211 by means of the support pad 25.

[0064] Please see Figure 5 The support assembly 20 also includes a limiting member 26, which covers at least one end of the slot near the grip portion 312. In other words, the limiting member 26 can... Figure 5 The cover shown is only applied to the end of the slot near the grip 312, or it can be like this. Figure 13 The other parts of the support plate 23 are also shown.

[0065] The limiting member 26 can be a relatively hard material, such as plastic, or a relatively soft material, such as soft rubber. The way the limiting member 26 is placed on the end of the slot near the gripping part 312 is not limited. For example, the limiting member 26 can be bonded, welded, or fastened to the support plate 23.

[0066] Figure 5The blocking member 24 covers the limiting member 26. The blocking member 24 can be connected to the limiting member 26. For example, the blocking member 24 can be bonded to the limiting member 26 to constrain the limiting member 26 and prevent it from loosening. In other embodiments, the blocking member 24 may only contact the limiting member 26 without being connected to it.

[0067] For example, the hardness of the limiting member 26 can be greater than the hardness of the blocking member.

[0068] In other embodiments, the shielding member 24 may also be arranged to avoid the limiting member 26, which is equivalent to the shielding member 24 not covering the limiting member 26.

[0069] The limiting member 26 can limit the operation part 311 to prevent the operation part 311 from coming out of the slot when the user applies force to the grip part 312.

[0070] Please see Figure 5 The support plate 23 can be recessed in a portion of its area on either side of the groove to form a limiting groove 23b, and the portion of the limiting member 26 located at the groove opening is disposed within the limiting groove 23b. The limiting groove 23b is mainly used to limit the portion of the limiting member 26 located at the groove opening. In addition, the portion of the limiting member 26 located at the groove opening is disposed within the limiting groove 23b, and this portion may not extend out of the limiting groove 23b, or only a portion of it may extend out of the limiting groove 23b. Thus, the side of the support plate 23 with the receiving groove 211 can be kept approximately flat.

[0071] Please see Figures 12 to 16 The receiving hole 212 is provided through the support plate 23, and the receiving groove 211 has a connecting hole 213 for connecting the receiving groove 211 and the receiving hole 212.

[0072] Please continue reading. Figures 13 to 16 The limiting member 26 includes a first limiting part 261, a connecting part 262, and a fixing part 263. The first limiting part 261 and the fixing part 263 are located at opposite ends of the connecting part 262, and are bent and extended on the same side relative to the connecting part 262. The first limiting part 261 covers the position near the slot and the connecting hole 213, and the connecting part 262 covers the wall surface where the connecting hole 213 is located. That is, the connecting part 262 is located on the side of the support plate 23 where the connecting hole 213 is provided, but the connecting part 262 does not obstruct the connecting hole 213. The first limiting part 261 and the fixing part 263 are respectively provided on opposite sides of the support plate 23.

[0073] In other words, the limiting member 26 is roughly C-shaped. When the limiting member 26 is installed on the support plate 23, the fixing part 263 is located on the side of the support plate 23 away from the first limiting part 261. This kind of limiting member 26 can improve the stability of the connection with the support plate 23, thereby improving the limiting effect.

[0074] Please see Figure 13 The blocking member 24 can be bonded to the first limiting part 261 to constrain the limiting member 26.

[0075] To facilitate the installation of the C-shaped limiting component and the operating body, the operating part 311 includes a first rod 3111 and a second rod 3112, which are split structures. That is, the first rod 3111 and the second rod 3112 are two separable sections. The first rod 3111 is located in the receiving groove 211, one end of the second rod 3112 is connected to the gripping part 312, and the end of the second rod 3112 facing away from the gripping part 312 extends into the receiving groove 211 from the connecting hole 213 and connects to the first rod 3111.

[0076] Figure 5 The second rod 3112 is integrally formed with the gripping part 312. In other embodiments, the second rod 3112 and the gripping part 312 can be detachably connected, such as by snap-fitting or fastening with screws or other fasteners. Alternatively, the second rod 3112 and the gripping part 312 can be non-detachably connected, such as by bonding or welding. The connection between the first rod 3111 and the second rod 3112 can be a detachable connection, such as by snap-fitting or fastening with screws or other fasteners, or a non-detachable connection, such as by bonding or welding.

[0077] Specifically, with Figure 5 Taking the operating entity 31 shown as an example, because Figure 5 The second rod 3112 of the operating body 31 shown is integrally formed with the grip part 312. Therefore, when installing the operating body 31, it is only necessary to first place the first rod 3111 into the receiving groove 211, and then insert the end of the second rod 3112 away from the grip part 312 into the receiving groove 211 from the connecting hole 213 and connect it with the first rod 3111. For operating bodies 31 where the second rod 3112 and the grip part 312 are not integrally formed, the second rod 3112 can be connected to the grip part 312 before placing the first rod 3111 into the receiving groove 211.

[0078] Setting the operating part 311 into a split first rod 3111 and second rod 3112 facilitates the installation of the operating body 31 and improves the installation efficiency of the operating body 31.

[0079] Please see Figure 2A positioning element 27 can be provided on one side of the support plate 23. The positioning element 27 is rotatably connected to the connecting component 10. In other words, the rotation of the support component 20 relative to the connecting component 10 can be achieved through the positioning element 27.

[0080] Please see Figure 6 and Figure 7 The connecting component 10 is provided with first locking teeth 11 arranged in an arc shape. The operating component 30 includes a locking portion 32 with second locking teeth 322a. The locking portion 32 is located at the end of the operating portion 311 away from the grip portion 312. The second locking teeth 322a engage with the first locking teeth 11 to lock the supporting component 20 and the connecting component 10. That is, when the first locking teeth 11 and the second locking teeth 322a are separated, the supporting component 20 can rotate relative to the connecting component 10. When the second locking teeth 322a engage with the first locking teeth 11, the supporting component 20 can be locked onto the connecting component 10.

[0081] Please see Figure 6 The latching part 32 includes a connecting part 321 and a toothed part 322 having a second tooth 322a. The connecting part 321 extends into the support plate 23 and connects to the operation part 311. The toothed part 322 is at least partially disposed outside the support plate 23.

[0082] Figure 6 The connecting part 321 and the locking tooth part 322 shown are integrally formed. In other embodiments, the connecting part 321 and the locking tooth part 322 can also be a separate structure. That is, the connecting part 321 and the locking tooth part 322 can also be two independent parts. The independent connecting part 321 and the locking tooth part 322 can be fixed together by detachable means such as snap-fitting and fastening, or they can be fixed together by non-detachable means such as welding and bonding.

[0083] The connection sub-part 321 facilitates the connection between the snap-fit ​​part 32 and the operating part 311 located inside the support plate 23, while the snap-fit ​​sub-part 322 facilitates the engagement of the second snap-fit ​​tooth 322a with the first snap-fit ​​tooth 11. This improves the ease of assembly of the operating component 30 and the connecting component 10. In addition, by providing the snap-fit ​​part 32, which includes the connection sub-part 321 and the snap-fit ​​sub-part 322, a transfer function can be provided, that is, the connection position between the operating component 30 and the connecting component 10 can be transferred to the outside of the support plate 23, thereby providing conditions for placing the operating body 31 inside the support component 20.

[0084] Please see Figure 6The operating component 30 includes an elastic reset member 33. When the operating body 31 is pulled, the elastic reset member 33 undergoes elastic deformation to unlock the support component 20 and the connecting component 10. When the operating body 31 is released, the operating body 31 resets under the elastic force of the elastic reset member 33 to lock the support component 20 and the connecting component 10.

[0085] Specifically, the elastic reset element 33 can be a spring, disc spring, elastic silicone, or other element with elastic force.

[0086] When the user holds the grip part 312 and pulls or pushes the operating body 31, the operating body 31 drives the locking part 32 to move away from the connecting component 10, and the elastic reset member 33 will also undergo elastic deformation. When the operating body 31 drives the locking part 32 to the position where the second locking tooth 322a separates from the first locking tooth 11, the support component 20 and the connecting component 10 are unlocked.

[0087] After unlocking, if the operating body 31 is released, that is, the user loosens the grip 312, the elastic reset member 33 can be reset under the action of elastic force. During the reset process, the elastic reset member 33 drives the operating component 30 to move closer to the connecting component 10 until the second locking tooth 322a engages with the first locking tooth 11, and the support component 20 is locked onto the connecting component 10 again.

[0088] Please see Figure 6 The elastic reset member 33 can be provided along the extension direction of the operating part 311 and abut against the locking part 32. That is, when the operating body 31 is pulled, the locking part 32 causes the elastic reset member 33 to undergo elastic deformation by squeezing the elastic reset member 33. When the operating body 31 is released, the elastic reset member 33 pushes the locking part 32 to move the operating component 30 toward the connecting component 10.

[0089] Please see Figure 6 The positioning member 27 has a protrusion 271 and a reset member receiving cavity 272. The part of the connecting assembly 10 with the first locking tooth 11 is rotatably connected to the protrusion 271. The reset member receiving cavity 272 is located on the side of the locking part 32 away from the first locking tooth 11. The elastic reset member 33 is installed in the reset member receiving cavity 272. That is to say, the elastic reset member 33 can be accommodated in the reset member receiving cavity 272 to facilitate the fixation of the elastic reset member 33.

[0090] Please see Figure 6 The positioning member 27 includes a cover 273 with an installation port, the cover 273 covers one side of the support plate 23, the installation port is located on the side of the cover 273 away from the support plate 23, and the protrusion 271 is located inside the cover 273 and is rotatably connected to the connecting assembly 10 via the installation port.

[0091] The cover 273 can cover the protrusion 271, the elastic reset member 33, the snap-fit ​​part 32 and other components, so that these components are not exposed. During cleaning and disinfection, only the outer surface of the cover 273 needs to be cleaned and disinfected. This can further improve the convenience of cleaning and disinfecting the arm support device 100.

[0092] Please see Figure 6 and Figure 7 The connecting assembly 10 includes a clamping body 12, a clamping arm 13, and an elastic element. The clamping body 12 has a clamping wall, and the clamping arm 13 is connected to the clamping body 12 and can rotate relative to the clamping wall. A clamping space for clamping is formed between the clamping wall and the clamping arm 13. The clamping space is used to accommodate the object to be clamped, such as the side rail 200 of an operating table. The elastic element drives the clamping arm 13 to rotate relative to the clamping wall. That is, by driving the clamping arm 13 to rotate relative to the clamping wall, the elastic element can adjust the distance between the clamping wall and the clamping arm 13 so that the clamping body 12 and the clamping arm 13 can clamp the object.

[0093] For example, the elastic element can be a torsion spring.

[0094] Please continue reading. Figure 6 and Figure 7 A handle 14 is connected to the clamping arm 13 and exposed outside the clamping body 12. By driving the handle 14, the clamping wall and the clamping arm 13 can be released. The handle 14 is the part where the user applies force. When it is necessary to release the clamping body 12 and the clamping arm 13 from the clamped object, by pressing the handle 14, the handle 14 drives the clamping arm 13 to rotate relative to the clamping wall, thus releasing the clamping wall and the clamping arm 13.

[0095] Please see Figure 6 and Figure 7 The clamping body 12 is provided with a second limiting part 12a, which is used to limit the range of motion of the handle 14. That is, the second limiting part 12a cooperates with the handle 14 to allow the handle 14 to move within a set range. When it is necessary to fix the connecting component 10 to the clamped object, the user presses the handle 14 to move the handle 14 to the position where it abuts against the second limiting part 12a. Then, the user aligns the clamping space formed between the clamping wall and the clamping arm 13 with the clamped object, allowing the object to enter the clamping space. Then, the user releases the handle 14, and the clamping body 12 and the clamping arm 13 can clamp the object. This means that the user does not need to press the handle 14 to its limit position to complete the clamping of the connecting component 10, thereby improving the convenience of operation.

[0096] For example, please refer to Figure 6 and Figure 7The second limiting part 12a can be a limiting hole that passes through the clamping body 12, and the handle 14 passes through the limiting hole. That is to say, the handle 14 limits the range of motion by abutting against the side wall of the limiting hole.

[0097] Please see Figure 2 and Figure 3 The support plate 23 can be provided with strap fixing holes 23a for the strap to pass through.

[0098] The straps are used to bind and secure the arm.

[0099] In related technologies, straps are usually fixed to the support plate using Velcro or screws. Too many parts can easily cause dirt to accumulate and are not easy to clean and disinfect.

[0100] In this embodiment, the strap fixing hole 23a is directly set on the support plate 23. The strap can be installed on the support plate 23 by passing through the strap fixing hole 23a. Thus, the components such as Velcro and screws used to fix the strap can be eliminated, which not only facilitates cleaning and disinfection, but also improves the convenience of strap installation.

[0101] Please see Figure 2 and Figure 3 The support plate 23 has a relatively long length, and the strap fixing hole 23a extends along the length of the support plate 23. That is to say, the strap can slide within the strap fixing hole 23a to achieve adjustable position of the strap.

[0102] Please see Figure 2 and Figure 3 Multiple strap fixing holes 23a can be provided on the same side of the support plate 23. The multiple strap fixing holes 23a are spaced apart along the length direction so as to adjust the position of the straps or increase or decrease the number of straps as needed.

[0103] Please see Figure 2 and Figure 3 The support plate 23 has a shorter width direction, and strap fixing holes 23a can be provided on opposite sides of the support plate 23 along the width direction. The same strap can pass through the strap fixing holes 23a provided on opposite sides along the width direction.

[0104] Another embodiment of this application (the second embodiment) provides an arm support device 100, which includes a connecting component 10, a support component 20, and an operating component 30.

[0105] The connecting assembly 10 is used to mount the arm support device 100 at a position such as the side rail 200 of the operating table. The support assembly 20 is used to support the arm. The support assembly 20 is rotatably connected to the connecting assembly 10, and the rotation angle is adjustable. The operating assembly 30 cooperates with the connecting assembly 10 to lock and / or release the rotation angle between the support assembly 20 and the connecting assembly 10.

[0106] The operating component 30 includes an operating body 31 that can move relative to the supporting component 20. Please refer to [link / reference]. Figure 5 The operating body 31 includes an operating section 311 and a grip section 312 disposed at one end of the operating section 311. The grip section 312 is the part used by the user to apply force to the operating body 31; for example, the user can pull or push the grip section 312 to move the operating body 31. The operating section 311 includes a first segment and a second segment. The end of the second segment opposite to the first segment is connected to the grip section 312, and the length of the first segment is greater than the length of the second segment. The first segment is hidden inside the support assembly 20.

[0107] In other words, at least the first segment is hidden inside the support component 20.

[0108] In other words, most of the area of ​​the operating part 311 can be hidden inside the support component 20, or in other words, most of the area of ​​the operating part 311 is obscured by the support component 20. This includes, but is not limited to, the following two situations: First, the first segment of the operating part 311 is not visible from the outside of the support component 20, but the second segment of the operating part 311 is visible; Second, the entire operating body 31 is not visible from the outside of the support component 20.

[0109] For the first scenario:

[0110] In one implementation, the specific implementation structure of the entire arm support device can be referred to the structure shown in the first embodiment above, in which a cover plate is placed on the opening 22 that is not in the accommodating space. In the first embodiment, when the connecting component 10 and the support component 20 are in the locked state, the part of the operating part 311 placed in the accommodating groove 211 is the first segment, and the part of the operating part 311 located in the accommodating hole 212 is the second segment.

[0111] In other implementations, compared to the first embodiment, only the receiving groove 211 can be provided. The end of the receiving groove 211 extends to the thickness surface of the support plate 23. The first section is accommodated in the receiving groove 211, and the second section and the gripping part 312 are located directly outside the entire support assembly 20.

[0112] For the second scenario:

[0113] In one implementation, the specific implementation structure of the entire arm support device can be referred to the structure shown in the first embodiment above, in which a cover plate is placed on the opening 22 of the accommodating space 21. In the first embodiment, when the connecting component 10 and the support component 20 are in the locked state, the part of the operating part 311 placed in the accommodating groove 211 is the first segment, and the part of the operating part 311 located in the accommodating hole 212 is the second segment.

[0114] Another embodiment of this application also provides an arm support device 100, please refer to... Figures 1 to 6 The arm support device 100 includes a connecting assembly 10, a support assembly 20, and a locking assembly 30. The support assembly 20 is rotatably connected to the connecting assembly 10, and the rotation angle is adjustable. The locking assembly 30 cooperates with the connecting assembly 10 to achieve and / or release the locking between the support assembly 20 and the connecting assembly 10. The locking assembly 30 includes a locking member 31 that is movable relative to the support assembly 20. When the connecting assembly 10 and the support assembly 20 are in a locked state, the locking member 31 is housed inside the support assembly 20.

[0115] The locking component 30 can be the operation component 30 described in the first embodiment above, or it can be other components with locking functions.

[0116] Please see Figures 1 to 6 The locking member 31 includes an operating part 311 and a gripping part 312 disposed at one end of the operating part 311. The operating part 311 is at least partially hidden inside the support component 20. That is, the operating part 311 is at least partially covered by the support component 20 and the operating part 311 is not visible from the outside of the support component 20.

[0117] It should be noted that when the locking component 30 is the operating component 30 described in the first embodiment above, the entire arm support device 100 is also as described in the first embodiment above, and will not be described again in this case.

[0118] In other embodiments, a portion of the operating part 311 may be hidden inside the support assembly 20. For example, the operating part 311 may include a first segment and a second segment, with the end of the second segment opposite to the first segment connected to the gripping part 312, and the length of the first segment being greater than the length of the second segment. The first segment is hidden inside the support assembly 20. That is, most of the operating part 311 may be hidden inside the support assembly 20, or in other words, most of the operating part 311 may be obscured by the support assembly 20, and the first segment of the operating part 311 may not be seen from the outside of the support assembly 20. The specific structure of the arm support assembly 100 in this embodiment can be found in the second embodiment, and will not be described again here.

[0119] Please see Figure 6 and Figure 7The connecting component has multiple locking parts arranged in an arc shape. The locking component locks the support component and the connecting component by engaging with the locking parts.

[0120] There are various ways in which the locking component 30 and the locking sub-part can lock together. For example, in one embodiment, the locking part is a first locking tooth 11. The locking component 30 also includes a locking part 32 disposed at the end of the operating part 311 away from the gripping part 312. The locking part 32 has a second locking tooth 322a. The second locking tooth 322a engages with the first locking tooth 11 to lock the support component 20 and the connecting component 10.

[0121] In another embodiment, the locking part can be a socket, and the operating part 311 locks the support component 20 and the connecting component 10 by engaging with the corresponding socket. That is, each socket corresponds to a different rotation angle. When the support component 20 rotates to the current required angle, the operating part 311 locks the support component 20 and the connecting component 10 by inserting into the socket corresponding to the current angle.

[0122] In another embodiment, the locking part can be a plug-in post, and the end of the operating part 311 away from the gripping part 312 has a slot. The slot engages with the corresponding plug-in post to lock the support assembly 20 and the connecting assembly 10. That is, each plug-in post corresponds to a different rotation angle. When the support assembly 20 rotates to the currently required angle, the slot engages with the plug-in post corresponding to the current angle to lock the support assembly 20 and the connecting assembly 10.
