Description

Technical Field

[0001] This application relates to the field of mechanical connection technology, and more specifically, to a hooking device, system, and method. Background Technology

[0002] Mounting devices are typically used to attach the device itself to a target. For example, when mounting a surveillance camera, the device itself can be the camera, and the target can be a horizontal bar on a support frame erected in the area to be monitored. Another example is mounting an equipotential bonding display; the device itself can be the equipotential bonding display, and the target can be a power cable. These mounting devices achieve attachment by triggering the mounting mechanism as the device approaches the target.

[0003] Current attachment devices primarily achieve attachment by having at least two swing-connected arms enter a attachable state under the action of an elastic element. The main process of entering the attachable state involves the attachment arms being kept in a non-attached state, or rather, restricted from entering the attachable state under the action of a trigger element. As the attachment device approaches the target, the trigger element contacts the target and moves under the target's contact, thus removing the restriction on the attachment arms entering the attachable state; that is, the attachment device is triggered. Therefore, under the action of the attachment arms, attachment to the target is achieved.

[0004] Current types of attachment devices involve at least two arms swinging under the action of their elastic components during the attachment process, requiring coordination between these swinging arms. However, these devices often suffer from insufficient coordination, leading to interference between the arms during swing and hindering successful attachment to the target. In other words, current attachment devices are prone to failure during attachment. This is especially true when the device itself is an equipotential bonding indicator, which has a higher probability of failure when attaching to power cables. Furthermore, equipotential bonding failure can prevent the indicator from accurately indicating the power cable's energization status, potentially causing safety accidents. Summary of the Invention

[0005] The purpose of this application is to provide a hooking device, system and method, which uses long arms and short arms of different "lengths" on the device body as the main components in the process of hooking to the target. Since the lever arms of the long arms and short arms are different in the force that they need to overcome when swinging on the device body, the interference points of the long arms and short arms can be staggered during the pressing down of the long arms and short arms, thereby increasing the probability of successful hooking.

[0006] In a first aspect, this application provides a mounting device, including a device body, a long arm, a short arm, a support arm, a first elastic element, and a second elastic element; a first end of the long arm is rotatably connected to a first side of the end of the device body via the first elastic element; a first end of the short arm is rotatably connected to a second side of the end of the device body via the second elastic element; a first end of the support arm is rotatably connected to a second end of one of the long arm and the short arm; wherein the distance between the first and second ends of the long arm is greater than the distance between the first and second ends of the short arm, and the rotation planes of the long arm and the short arm are parallel; wherein, when the second end of the support arm abuts against the short arm or the long arm, the long arm and the short arm form an opening with an intermediate region; and, when the second end of the support arm disengages from abutting against the short arm, the long arm and the short arm, respectively, move along the rotation plane and approach the end of the device body under the action of the first elastic element and the second elastic element.

[0007] The aforementioned hooking device uses long and short arms of different "lengths" (the distance between the first and second ends) on the device body as the main components for hooking onto the target. Since the lever arms that the long and short arms need to overcome when swinging on the device body are different, the swinging of the long and short arms will not be synchronized. This avoids the point where the long and short arms interfere with each other during the downward pressing process, thereby reducing the probability of hooking failure due to interference between the long and short arms after the support arm disengages and comes into contact with the long or short arm. Furthermore, in the state of waiting to be attached, since the two ends of the support arm are located at the second end of the long arm and the second end of the short arm respectively, and the "length" of the long arm and the short arm is different, when the end of the device body is facing directly upward, the straight line defined by the first end and the second end of the support arm is in an inclined state. This makes the angle between the long arm and the short arm larger, that is, the opening in the middle area between the long arm and the short arm is larger. Ultimately, this further facilitates the target to enter the middle area between the long arm and the short arm during the attachment process, increasing the probability of successful attachment.

[0008] In conjunction with the first aspect, optionally, the long arm has a length direction extending along the direction of the first end and the second end of the long arm; the long arm has a hollow portion extending along the length direction; during the process of the second end of the support arm disengaging from the short arm, the short arm passes through the hollow portion.

[0009] The aforementioned attachment device, by creating a perforation in the long arm, allows the short arm to pass through the perforation when triggered for attachment, continuing its uninterrupted swing. Furthermore, the line connecting the first ends of the long and short arms is parallel to the plane of rotation of the long arm. In this configuration, when the long and short arms press against the ends of the device body through their swinging motion, there is no gap, unlike in traditional attachment devices where two arms press parallel to each other and have a gap between them. Such a gap allows slender attachment targets, such as power cables, to pass through, causing detachment. In other words, the perforation design in the long arm prevents such gaps between the long and short arms, reducing the probability of detachment when the attachment device is attached to a target. This improves the attachment stability and reliability of the device.

[0010] In conjunction with the first aspect, optionally, the support arm has a third arcuate portion between the first end and the second end; the third arcuate portion is curved along the plane of rotation of the support arm; wherein, when the second end of the support arm abuts against the short arm or the long arm, the opening of the third arcuate portion faces away from the end of the device body.

[0011] The aforementioned attachment device, through a third arc-shaped section designed on the support arm, ensures that the middle of the support arm is recessed towards the device body when it is in the engagement state, abutting with the long or short arm. As the attachment device approaches the target to trigger engagement, the target needs to be positioned further within the middle area between the short and long arms. This further reduces the probability that, after the support arm detaches and abuts with the long or short arm, the long and / or short arm will not press the target under it when it swings and presses against the end of the device body. In other words, it further reduces the probability of engagement failure or failure to achieve the desired engagement, and further increases the probability of successful engagement.

[0012] In conjunction with the first aspect, optionally, the plane of rotation of the support arm is parallel to the plane of rotation of the long arm; the first end of the support arm is rotatably connected to the second end of the long arm via a third elastic element; the swing trajectory of the second end of the support arm intersects with the hollow portion; the third elastic element is configured to output a third torque to the first end of the support arm; wherein the direction of the third torque is consistent with the direction of the second torque applied by the second elastic element.

[0013] The aforementioned mounting device, by incorporating a third elastic element into the support member, allows the support arm to swing and press against either the device body or the short arm when the short and long arms press the mounting target against the end of the device body. In this situation, if the mounting device is to be detached from the mounting target, not only must the mounting target break free from the pressure of the short and long arms, but it must also break free from the pressure of the support arm. Thus, the support arm acts as an additional layer of protection for the mounting device in the mounted state, further enhancing the mounting stability and reliability of the device.

[0014] In conjunction with the first aspect, optionally, the distance between the first end and the second end of the support arm is greater than the length difference; wherein, the length difference is equal to the distance between the first end and the second end of the long arm minus the distance between the first end and the second end of the short arm; and the distance between the first end and the second end of the support arm is less than the distance between the first end and the second end of the long arm.

[0015] The aforementioned mounting device, by defining the relationship between the distances at both ends of the support arm, the long arm, and the short arm, ensures that the support arm can properly open the long and short arms and obtain a sufficiently large opening in the middle area between the long and short arms. Furthermore, it ensures that the support arm will not be interfered with by the first end of the long arm or other parts near the first end during its swing on the long arm, thereby further improving the smoothness of the mounting process.

[0016] In conjunction with the first aspect, optionally, a first anti-slip surface is provided at the position where the short arm contacts the second end of the support arm; and / or a second anti-slip surface is provided at the second end of the support arm.

[0017] The aforementioned mounting device, by providing a first anti-slip surface and / or a second anti-slip surface, ensures a more stable connection between the second end of the support arm and the short arm when in the mounting state. This reduces the probability of the connection between the support arm and the short arm prematurely disengaging due to vibration or other factors before the mounting device approaches the mounting target and the support arm is pushed open by the target. In other words, it further increases the probability of successful mounting.

[0018] In conjunction with the first aspect, optionally, the long arm includes a support arm clamping portion located at its second end; the support arm clamping portion has a support arm clamping surface; the support arm clamping surface is parallel to the rotation plane of the support arm and clamps the first end of the support arm.

[0019] The aforementioned hooking device, through the constraint of the support arm clamping surface of the support arm clamping part, restricts the swing of the support arm on the long arm to the plane where the support arm clamping surface is located. Since the support arm clamping surface is parallel to the original plane of rotation of the support arm, it also restricts the swing of the support arm in directions outside its plane of rotation, thereby improving the stability and reliability of the hooking process after being triggered for hooking, and ultimately further increasing the probability of successful hooking.

[0020] In conjunction with the first aspect, optionally, the device further includes a long-arm clamping portion and a short-arm clamping portion; the long-arm clamping portion is disposed on a first side of the end of the device body and has a long-arm clamping surface; the long-arm clamping surface is parallel to the rotation plane of the long arm and clamps the first end of the long arm; the short-arm clamping portion is disposed on a second side of the end of the device body and has a short-arm clamping surface; the short-arm clamping surface is parallel to the rotation plane of the short arm and clamps the first end of the short arm.

[0021] The aforementioned hooking device, through the constraints of the long arm clamping surface and the short arm clamping surface, restricts the swinging of the long arm and short arm on the device body to the planes where the long arm clamping surface and the short arm clamping surface are located, respectively. Since the long arm clamping surface and the short arm clamping surface are parallel to the original rotation planes of the long arm and short arm, respectively, the swinging of the long arm and short arm in directions outside their rotation planes is also restricted. This further improves the stability and reliability of the hooking device during the hooking process after being triggered, and ultimately further increases the probability of successful hooking.

[0022] In conjunction with the first aspect, optionally, the elastic coefficient of the first elastic element is less than the elastic coefficient of the second elastic element.

[0023] In the aforementioned mounting device, because the lever arm of the force that the long arm needs to overcome when swinging on the device body is greater than that of the short arm, the time required for the long arm to reach the position pressing against the device body through swinging is generally longer than the time required for the short arm. Furthermore, by using a first elastic element with a lower elastic coefficient than the second elastic element, the first torque provided by the first elastic element to the long arm is less than the second torque provided by the second elastic element to the short arm. This further increases the time difference between the time required for the long arm to press against the device body and the time required for the short arm, thereby further reducing the probability of interference between the long and short arms during swinging, and the probability that the short arm fails to press against the target after the long arm presses against it. Ultimately, this also further increases the probability of successful mounting.

[0024] In conjunction with the first aspect, optionally, the long arm has a first arcuate portion between its first end and second end; the first arcuate portion is curved along the plane of rotation of the long arm; wherein, when the second end of the support arm abuts against the short arm or the long arm, the opening of the first arcuate portion faces the short arm; the short arm has a second arcuate portion between its first end and second end; the second arcuate portion is curved along the plane of rotation of the long arm; wherein, when the second end of the support arm abuts against the short arm or the long arm, the opening of the second arcuate portion faces the long arm.

[0025] The aforementioned mounting device, by setting a first arc-shaped part and a second arc-shaped part in the middle of the long arm and the short arm respectively, allows the first arc-shaped part and the second arc-shaped part to form a certain gap with the device body when the long arm and the short arm press the mounting target on the device body, so as to accommodate the mounting target and avoid the mounting target being crushed due to excessive swinging force of the long arm and the short arm.

[0026] In conjunction with the first aspect, optionally, a groove is provided on the device body between the first end of the long arm and the first end of the short arm; the groove is perpendicular to the rotation plane of the long arm.

[0027] The aforementioned mounting device, by providing grooves on the device body, allows the target to be received when it is pressed against the device body by the long and short arms. This not only prevents the target from being crushed due to excessive swinging force of the long and short arms, but also limits the position of the target, preventing it from swinging or rotating on the device body to a certain extent, thereby further improving the stability of the mounting device when it is attached to the target.

[0028] In conjunction with the first aspect, optionally, the mounting device is used to mount a mounting target; wherein, both the first and second sides of the end of the device body are far from the center position of the end of the device body; the distance between the first and second sides of the end of the device body is greater than twice the diameter of the cross-section of the mounting target; the cross-section is a section parallel to the plane of rotation of the long arm when the device is mounted on the mounting target; the distance between the first and second ends of the support arm is greater than the distance between the first and second sides of the end of the device body.

[0029] The aforementioned mounting device, by designing that the distance between the first and second ends of the device body is greater than twice the diameter of the cross-section of the target, allows the long and short arms to be nearly horizontal when pressing the power cable onto the device body, thereby further improving the stability of the mounting device when attached to the target. Furthermore, by ensuring that the distance between the first and second ends of the support arm is greater than the distance between the first and second ends of the device body, the opening in the middle area between the long and short arms is enlarged, further facilitating the target's entry into the middle area of ​​the long and short arms during the mounting process, ultimately increasing the probability of successful mounting.

[0030] In conjunction with the first aspect, the mounting target may optionally include power cables.

[0031] The aforementioned mounting device, by using the mounting devices provided in the various embodiments of this application for mounting power cables, improves the smoothness of mounting power cables and the stability when mounting power cables, thereby reducing the risk to operators when performing power-related operations, reducing the probability of damage caused by equipment falling from heights, and thus avoiding safety accidents.

[0032] Secondly, this application provides a mounting system including a receiving mechanism and a mounting device described in the first aspect; the receiving mechanism includes a housing; wherein the housing surrounds a receiving space having an opening; the receiving space is used to receive the device body of the mounting device, and the opening is used for the mounting device to pass through during entry into and exit from the receiving space.

[0033] The above-described mounting system has the same beneficial effects as the mounting device provided in the first aspect or any optional embodiment of the first aspect, and will not be described in detail here.

[0034] In conjunction with the second aspect, optionally, the receiving mechanism includes an image acquisition device; the image acquisition device is disposed outside the housing of the receiving mechanism; wherein the angle between the field of view of the image acquisition device and the orientation of the opening is an acute angle, and the field of view of the image acquisition device includes the orientation of the opening.

[0035] The aforementioned mounting system, by configuring an image acquisition device on the mounting system, facilitates users to adjust the operation based on the images acquired by the image acquisition device, thereby improving the convenience of the mounting system during the mounting process.

[0036] Thirdly, this application provides a hooking method applied to a hooking system; wherein the hooking system includes a receiving mechanism and a hooking device; the hooking device includes a device body, a long arm, a short arm, and a support arm; the method includes: moving the hooking system closer to the hooking target and using the support arm to abut against the hooking target; moving the hooking system further closer to the hooking target until the support arm disengages from the abutment of the short arm or the long arm; and, when the long arm and the short arm are pressing against the hooking target together, moving the receiving mechanism back.

[0037] The above-described mounting method has the same beneficial effects as the mounting system provided in the second aspect or any optional embodiment of the second aspect, and will not be described in detail here.

[0038] In conjunction with the third aspect, optionally, the step of bringing the attachment system closer to the attachment target and having the support arm abut against the attachment target includes: the drone bringing the attachment system closer to the attachment target and having the support arm abut against the attachment target; the step of bringing the attachment system closer to the attachment target until the support arm disengages from the abutment of the short arm or long arm includes: the drone bringing the attachment system closer to the attachment target until the support arm disengages from the abutment of the short arm; the step of bringing the receiving mechanism back includes: the drone bringing the receiving mechanism back.

[0039] The aforementioned splicing method, which uses a drone to power the splicing system, eliminates the need to replace poles of varying lengths depending on the height of the target cable compared to manual methods using support poles, thus significantly improving splicing flexibility. Furthermore, using a drone to power the splicing system almost completely isolates the user from direct or indirect physical contact with the target cable, thereby enhancing safety during the splicing process.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] Please refer to Figure 1 and Figure 2 , Figure 1 This is a perspective view of the mounting device 100 provided in the embodiments of this application; Figure 2 yes Figure 1 A schematic diagram of the mounting device 100 before attachment from a neutral viewing angle. The mounting device provided in this application embodiment may include a device body 110, a long arm 120, a short arm 130, a support arm 140, a first elastic element 150, and a second elastic element 160. The device body 110 may be the main part of the mounting device 100 that is attached via the long arm 120, short arm 130, etc. Specifically, the device body 110 may be a monitoring camera, an equipotential bonding display, or a similar device. The first elastic element 150 may specifically be a first spring or a first spring bar, etc., and the second elastic element 160 may specifically be a second spring or a second spring bar, etc.

[0055] The long arm 120 and the short arm 130 can both be elongated. The elongated shape of the long arm 120 and the short arm 130 is not necessarily straight; they can also be curved. The distance between the first and second ends of the long arm 120 can be greater than the distance between the first and second ends of the short arm 130, and the planes of rotation of the long arm 120 and the short arm 130 can be parallel. In other words, the length of space occupied by the long arm 120 can be greater than the length of space occupied by the short arm 130.

[0056] The first end of the long arm 120 can be rotatably connected to the first side of the end of the device body 110 via the first elastic member 150. That is, while one end of the long arm 120 is rotatably connected to the device body 110, the entire long arm 120 is swayably connected to the device body 110. It can also swing towards the short arm 130 under the action of the first elastic member 150, or maintain a tendency to swing towards the short arm 130. For example: Figure 1 The counterclockwise direction in the middle. Specifically, the end of the device body 110 can be the top of the device body 110, the bottom of the device body 110, or other parts of the device body 110.

[0057] The first end of the short arm 130 can be rotatably connected to the second side of the end of the device body 110 via the second elastic member 160. Similarly, with one end of the short arm 130 rotatably connected to the device body 110, the entire short arm 130 is swayably connected to the device body 110. It can also sway towards the long arm 120 under the action of the second elastic member 160, or maintain a tendency to sway towards the long arm 120. For example: Figure 1 The clockwise direction in the middle.

[0058] A first end of the support arm 140 can be rotatably connected to a second end of one of the long arm 120 and the short arm 130. The other end of the support arm 140 can at least be used to abut against the second end of the other of the long arm 120 and the short arm 130 to limit the swinging of the long arm 120 and the short arm 130 under the action of the first elastic member 150 and the second elastic member 160, respectively. For example, as... Figure 1As shown, the support arm 140 can be roughly positioned horizontally between the long arm 120 and the short arm 130, maintaining a certain opening between them. However, under the action of the first elastic element 150 and the second elastic element 160, the long arm 120 and the short arm 130 respectively apply force to the support arm 140, thus "clamping" the support arm 140 between the long arm 120 and the short arm 130. This prevents the long arm 120 from swinging clockwise in its natural state and the short arm 130 from swinging counterclockwise in its natural state, thereby increasing the opening between the long arm 120 and the short arm 130. The support arm 140 then disengages from the contact with either the long arm 120 or the short arm 130 and swings counterclockwise under gravity. When the mounting device 100 is not mounted to a target, the long arm 120, the short arm 130, and the support arm 140 on the mounting device 100 can be in this ready-to-mount state.

[0059] When the second end of the support arm 140 abuts against the short arm 130 or the long arm 120, the long arm 120 and the short arm 130 can form an opening with a middle region. And when the second end of the support arm 140 disengages from the short arm 130, the long arm 120 and the short arm 130 can move along the plane of rotation and approach the end of the device body 110 under the action of the first elastic member 150 and the second elastic member 160, respectively.

[0060] Continue with Figure 1 For example, when the mounting device 100 is in the aforementioned ready-to-mount state, it can be manually moved to a high mounting target using tools such as a support pole, or it can be moved to a high mounting target, such as a power cable, using tools such as a drone. As the mounting device 100 approaches the power cable, the support arm 140 can be kept approximately perpendicular to the power cable. When the mounting device 100 moves to the point where the support arm 140 contacts the power cable, the mounting device 100 continues to move upwards. Under the contact of the power cable, the support arm 140 swings counterclockwise around the second end of the long arm 120, thereby disengaging the second end of the support arm 140 from the contact with the short arm 130. At this point, the power cable has entered the intermediate area between the long arm 120 and the short arm 130. Correspondingly, the restrictions on the long arm 120 and the short arm 130 are released, and the long arm 120 and the short arm 130 swing towards each other under the action of the first elastic member 150 and the second elastic member 160, respectively. After the long arm 120 and the short arm 130 swing at a certain angle, they will respectively rest on the power cable. As the long arm 120 and the short arm 130 continue to swing, they will eventually press down on the ends of the device body 110. In this state, the power cable is also pressed down under the long arm 120 and the short arm 130 and on the ends of the device body 110. The attached device 100 after being attached is as follows: Figure 3 As shown, Figure 3 yes Figure 1 A schematic diagram of the mounting device 100 after it has been mounted from a neutral viewing angle.

[0061] In the above implementation process, long arms 120 and short arms 130 with different "lengths" (distance between the first end and the second end) are respectively set on the device body 110 as the main components in the process of hanging on the target. Since the lever arms of the forces that the long arms 120 and the short arms 130 need to overcome when swinging on the device body 110 are different, the swinging of the long arms 120 and the short arms 130 will not be synchronized. This avoids the point where the long arms 120 and the short arms 130 interfere during the downward pressing process, thereby reducing the probability of hanging failure caused by interference between the long arms 120 and the short arms 130 after the support arm 140 disengages from the long arms 120 or the short arms 130 when it comes into contact with them. Furthermore, in the state of waiting to be attached, since the two ends of the support arm 140 are located at the second end of the long arm 120 and the second end of the short arm 130 respectively, and the "length" of the long arm 120 and the short arm 130 is different, when the end of the device body 110 is facing directly upward, the straight line defined by the first end and the second end of the support arm 140 is in an inclined state, which makes the angle between the long arm 120 and the short arm 130 larger, that is, the opening of the middle area between the long arm 120 and the short arm 130 larger. Ultimately, this further facilitates the target to enter the middle area between the long arm 120 and the short arm 130 during the attachment process, and increases the probability of successful attachment.

[0062] Please continue to refer to Figure 1 In some alternative embodiments, the long arm 120 may have a length direction extending along the direction of the first and second ends of the long arm 120. A hollow portion 121 extending along the length direction may be provided on the long arm 120. During the process of the second end of the support arm 140 disengaging from its contact with the short arm 130, the short arm 130 can pass through the hollow portion 121. When the short arm 130 passes through the hollow portion 121, it is in a swinging state under the action of the second elastic member 160. Therefore, in accordance with the spirit described above to avoid interference between the long arm 120 and the short arm 130, the support arm 140 should not continue to swing due to interference from the edge of the hollow portion 121 on the long arm 120 during the process of passing through the hollow portion 121, until it presses against the end of the device body 110.

[0063] In view of this, the vertical projection of the hollow portion 121 at the end of the device body 110, compared with the vertical short arm projection of the short arm 130 at the end of the device body 110, except for the edges at both ends of the vertical hollow portion projection along the straight line between the first and second ends of the long arm 120, can be designed not to intersect with the vertical short arm projection. For example, the vertical short arm projection is rectangular, parallel to the two sides of the straight line between the first and second ends of the long arm 120, and parallel to the vertical short arm projection.

[0064] In the above implementation process, by creating a cutout 121 on the long arm 120, the short arm 130 can pass through the cutout 121 on the long arm 120 and continue to swing without interference when triggered for attachment. Furthermore, the straight line containing the first ends of the long arm 120 and the short arm 130 is parallel to the plane of rotation of the long arm 120. In this case, when the long arm 120 and the short arm 130 respectively swing and press against the ends of the device body 110, there is no situation similar to the two conventional attachment arms pressing against the device body 110 parallel to each other, with a gap between the two attachment arms. Such a gap allows a thin, elongated attachment target, such as an electrical cable, to pass through, causing detachment. In other words, by designing the cutout 121 on the long arm 120, a similar gap between the long arm 120 and the short arm 130 is avoided, thereby reducing the probability of the attachment device 100 detaching when attached to an attachment target. This improves the stability and reliability of the mounting device 100.

[0065] Please continue to refer to Figure 2 and Figure 3 In some alternative embodiments, a third arcuate portion 141 may be provided between the first end and the second end of the support arm 140. The third arcuate portion 141 may be a circular arc, an elliptical arc, a hyperbolic arc, or other conical arcs, or other regular or irregular arcs.

[0066] The third arcuate portion 141 can be bent along the plane of rotation of the support arm 140. Wherein, when the second end of the support arm 140 abuts against the short arm 130 or the long arm 120, the opening of the third arcuate portion 141 can face away from the end of the device body 110. For example, Figure 2 The downward bend is shown in the diagram.

[0067] In the aforementioned implementation process, the third arc-shaped portion 141 designed on the support arm 140 ensures that, in the ready-to-hook state when the support arm 140 is in contact with the long arm 120 or the short arm 130, the middle portion of the support arm 140 is recessed towards the device body 110. During the process of the hooking device 100 approaching the hooking target to trigger hooking, the hooking target needs to be positioned deeper into the middle area between the short arm 130 and the long arm 120. This further reduces the probability that, after the support arm 140 disengages from the long arm 120 or the short arm 130, when the long arm 120 and the short arm 130 swing and press against the end of the device body 110, the long arm 120 and / or the short arm 130 will not press the hooking target under it. In other words, this further reduces the probability of hooking failure or hooking not achieving the expected result, and further increases the probability of successful hooking.

[0068] Please continue to refer to Figure 2 and Figure 3 In some alternative embodiments, the plane of rotation of the support arm 140 may be parallel to the plane of rotation of the long arm 120. Based on the parallelism between the plane of rotation of the long arm 120 and the plane of rotation of the short arm 130, and given that the second end of the support arm 140 is used to abut against the short arm 130, if the plane of rotation of the support arm 140 is parallel to the plane of rotation of the long arm 120, then the straight line containing the first ends of the long arm 120 and the first ends of the short arm 130 is collinear with the vertical projection of the support arm 140 onto the end of the device body 110.

[0069] The first end of the support arm 140 can be rotatably connected to the second end of the long arm 120 via a third elastic element 170. The third elastic element 170 can specifically be a third spring or a third spring bar, etc. That is, in the state to be attached, the second end of the support arm 140 abuts against the short arm 130.

[0070] The swing trajectory of the second end of the support arm 140 can intersect with the hollow part 121. This means that the support arm 140 can pass through the hollow part 121 without interference during the swinging process on the long arm 120.

[0071] The third elastic element 170 can be configured to output a third torque to the first end of the support arm 140. The direction of the third torque is consistent with the direction of the second torque applied by the second elastic element 160.

[0072] Combination Figure 2Taking a power cable as the mounting target, after the power cable pushes open the support arm 140, causing the support arm 140 to detach from the short arm 130, as described above, the short arm 130 and the long arm 120 will swing under the action of the first elastic member 150 and the second elastic member 160, respectively. In this embodiment, the support arm 140 will also swing clockwise on the long arm 120 under the action of the third elastic member 170. When the long arm 120 and the short arm 130 are respectively resting on the power cable and pressing the power cable onto the end of the device body 110, the second end of the support arm 140 will eventually press onto the short arm 130 or the end of the device body 110. Furthermore, under the action of the third elastic member 170, it will continue to maintain a clockwise swinging trend.

[0073] In the above implementation process, by configuring a third elastic element 170 on the support member, when the short arm 130 and the long arm 120 press the target onto the end of the device body 110, the support arm 140, under the action of the third elastic element 170, swings and presses against the device body 110 or the short arm 130. In this case, when the hanging device 100 is attached to the target, to detach it from the target, not only does the target need to break through the pressure of the short arm 130 and the long arm 120, but it also needs to break through the pressure of the support arm 140. Thus, the support arm 140 acts as another layer of protection for the hanging device 100 in the attached state, thereby further improving the hanging stability and reliability of the hanging device 100.

[0074] Please continue to refer to Figure 2 and Figure 3 In some optional embodiments, the distance between the first and second ends of the support arm 140 can be greater than the length difference. The length difference can be equal to the distance between the first and second ends of the long arm 120 minus the distance between the first and second ends of the short arm 130. Assuming that the support arm 140, long arm 120, and short arm 130 are all long, straight parts, then correspondingly, in this embodiment, the length of the support arm 140 is greater than the length difference between the long arm 120 and the short arm 130. This ensures that even in the theoretically extreme case, where the first end of the long arm 120 coincides with the first end of the short arm 130, both ends of the support arm 140 can still contact the second ends of the long arm 120 and the short arm 130, thereby separating the long arm 120 and the short arm 130.

[0075] The distance between the first and second ends of the support arm 140 can be less than the distance between the first and second ends of the long arm 120. Similarly, based on the aforementioned assumption, the length of the support arm 140 in this embodiment is also less than the length of the long arm 120, which ensures that the support arm 140 passes through the hollow portion 121 without interference during the swinging process on the long arm 120.

[0076] Those skilled in the art should understand that although the above description of the scheme and principle of the embodiments of this application is based on the assumption that the support arm 140, the long arm 120 and the short arm 130 are all long and straight parts, since the embodiments of this application define the distance between the two ends of the support arm 140, the long arm 120 and the short arm 130, rather than their actual length, even if at least one of the support arm 140, the long arm 120 and the short arm 130 is bent, the principle on which it is based is still as described above.

[0077] In the above implementation process, by limiting the relationship between the distances at both ends of the support arm 140, the long arm 120, and the short arm 130, it is ensured that the support arm 140 can properly open the long arm 120 and the short arm 130, and obtain a sufficiently large opening in the middle area between the long arm 120 and the short arm 130. Furthermore, it is ensured that the support arm 140 will not be interfered with by the first end of the long arm 120 or other parts near the first end during its swing on the long arm 120, thereby further improving the smoothness of the connection process.

[0078] Please continue to refer to Figure 2 In some optional embodiments, a first anti-slip surface 131 may be provided at the position where the short arm 130 contacts the second end of the support arm 140; and / or a second anti-slip surface 142 may be provided at the second end of the support arm 140.

[0079] The first anti-slip surface 131 can be a structural design with a rough surface at the contact position, or it can be anti-slip rubber or adhesive provided at the contact position, or it can be a magnet or electromagnet provided at the contact position. Similarly, the second anti-slip surface 142 can be a structural design with a rough surface at the second end of the support arm 140, or it can be anti-slip rubber or adhesive provided at the contact position, or it can be a magnet or electromagnet provided at the contact position.

[0080] In the above implementation process, by setting the first anti-slip surface 131 and / or the second anti-slip surface 142, the contact between the second end of the support arm 140 and the short arm 130 is relatively more stable in the waiting-to-be-attached state. This reduces the probability that the contact between the support arm 140 and the short arm 130 will prematurely detach due to factors such as vibration before the attachment device 100 approaches the attachment target and the support arm 140 is pushed open by the attachment target. In other words, it further improves the probability of successful attachment.

[0081] Please continue to refer to Figure 3In some alternative embodiments, the long arm 120 may include a support arm clamping portion 122 located at its second end. The support arm clamping portion 122 may have a support arm clamping surface. Exemplarily, two clamping plates may be disposed opposite each other at the second end of the long arm 120, with the second end of the support arm 140 located between the two clamping plates. A pivotable connection between the support arm 140 and the long arm 120 is achieved by a rotating pin passing through the two clamping plates and the second end of the support arm 140. In this case, the support arm clamping surface may specifically be the surfaces of the two clamping plates facing each other. The support arm clamping surface may be parallel to the plane of rotation of the support arm 140 and may clamp the first end of the support arm 140.

[0082] In the above implementation process, the swing of the support arm 140 on the long arm 120 is restricted to the plane where the support arm clamping surface is located by the constraint of the support arm clamping surface of the support arm clamping part 122. Since the support arm clamping surface is parallel to the original rotation plane of the support arm 140, the swing of the support arm 140 in directions outside its rotation plane is also restricted, thereby improving the stability and reliability of the hooking process of the hooking device 100 after being triggered for hooking, and ultimately further improving the probability of successful hooking.

[0083] Please continue to refer to Figure 3 In some optional implementations, the mounting device 100 provided in this application embodiment may further include a long arm clamping part 111 and a short arm clamping part 112.

[0084] The long arm clamping part 111 can be disposed on the first side of the end of the device body 110 and can have a long arm clamping surface. For example, two clamping plates can also be disposed opposite each other on the first side of the end of the device body 110, with the first end of the long arm 120 located between the two clamping plates. A pivoting pin passes through the two clamping plates and the first end of the long arm 120 to achieve a swingable connection between the long arm 120 and the device body 110. In this case, the long arm clamping surface can specifically be the surfaces of the two clamping plates facing each other. The long arm clamping surface can be parallel to the rotation plane of the long arm 120 and can clamp the first end of the long arm 120.

[0085] The short arm clamping part 112 can be disposed on the second side of the end of the device body 110 and can have a short arm clamping surface. Exemplarily, two clamping plates can also be disposed opposite each other on the second side of the end of the device body 110, with the first end of the short arm 130 located between the two clamping plates. A pivotable connection between the short arm 130 and the device body 110 is achieved by a rotating pin passing through the two clamping plates and the first end of the short arm 130. In this case, the short arm clamping surface can specifically be the surfaces of the two clamping plates facing each other. The short arm clamping surface can be parallel to the rotation plane of the short arm 130 and can clamp the first end of the short arm 130.

[0086] In the above implementation process, the swinging of the long arm 120 and the short arm 130 on the device body 110 is restricted to the planes where the long arm clamping surface and the short arm clamping surface are located, respectively, by the constraint of the long arm clamping surface and the short arm clamping surface. Since the long arm clamping surface and the short arm clamping surface are parallel to the original rotation plane of the long arm 120 and the short arm 130, the swinging of the long arm 120 and the short arm 130 in directions outside their rotation plane is also restricted, thereby further improving the stability and reliability of the hooking device 100 in the hooking process after being triggered for hooking, and ultimately further improving the probability of successful hooking.

[0087] In some alternative implementations, the elastic coefficient of the first elastic element 150 may be less than the elastic coefficient of the second elastic element 160.

[0088] In the above implementation process, since the lever arm of the force that the long arm 120 needs to overcome to swing on the device body 110 is greater than the lever arm of the force that the short arm 130 needs to overcome to swing on the device body 110, the time required for the long arm 120 to reach the position pressing on the device body 110 by swinging is usually greater than the time required for the short arm 130. Based on this, by using a first elastic element 150 with a lower elastic coefficient than the second elastic element 160, the first torque provided by the first elastic element 150 to the long arm 120 is less than the second torque provided by the second elastic element 160 to the short arm 130. This further increases the time difference between the time required for the long arm 120 to press on the device body 110 by swinging and the time required for the short arm 130, thereby further reducing the probability of interference between the long arm 120 and the short arm 130 during swinging, and the probability that the short arm 130 fails to press on the target after the long arm 120 presses on it. Ultimately, this also further increases the probability of successful attachment.

[0089] Please continue to refer to Figure 2 and Figure 3 In some alternative embodiments, a first arcuate portion 123 may be provided between the first and second ends of the long arm 120. The first arcuate portion 123 can be a circular arc, an elliptical arc, a hyperbolic arc, or other conical curve arcs, or other regular or irregular arcs. The first arcuate portion 123 can be bent along the plane of rotation of the long arm 120. Wherein, when the second end of the support arm 140 abuts against the short arm 130 or the long arm 120, the opening of the first arcuate portion 123 can face the short arm 130. For example, Figure 2 The curve to the right is shown in the diagram.

[0090] A second arcuate portion 132 may be provided between the first and second ends of the short arm 130. The second arcuate portion 132 can also be a circular arc, an elliptical arc, a hyperbolic arc, or other conical curve arcs, or other regular or irregular arcs. The second arcuate portion 132 can be bent along the plane of rotation of the long arm 120. Specifically, when the second end of the support arm 140 abuts against either the short arm 130 or the long arm 120, the opening of the second arcuate portion 132 can face the long arm 120. For example, Figure 2 The curve to the left is shown in the diagram.

[0091] In the above implementation process, by setting a first arc-shaped part 123 and a second arc-shaped part 132 in the middle part of each of the long arm 120 and the short arm 130 respectively, when the long arm 120 and the short arm 130 press the target onto the device body 110, the first arc-shaped part 123 and the second arc-shaped part 132 can respectively form a certain gap with the device body 110 to accommodate the target, thereby avoiding the target from being crushed due to factors such as excessive swing force of the long arm 120 and the short arm 130.

[0092] Please continue to refer to Figure 2 and Figure 3 In some alternative embodiments, a groove 113 may be provided on the device body 110 between the first end of the long arm 120 and the first end of the short arm 130. The groove 113 may be perpendicular to the plane of rotation of the long arm 120. Perpendicularity does not mean that the angle between the groove 113 and the plane of rotation of the long arm 120 must be an absolute 90°, but can be slightly inclined.

[0093] In the above implementation process, by providing a groove 113 on the device body 110, when the target is pressed onto the device body 110 by the long arm 120 and the short arm 130, the groove 113 can receive the target. In addition to further avoiding damage to the target caused by excessive swinging force of the long arm 120 and the short arm 130, the edge of the groove 113 also plays a limiting role for the target, which can prevent the target from swinging or rotating on the device body 110 to a certain extent, thereby further improving the stability of the hanging device 100 when it is attached to the target.

[0094] Please continue to refer to Figure 2 and Figure 3 In some optional implementations, the mounting device 100 provided in this application embodiment can be used to mount to a mounting target.

[0095] The first and second ends of the device body 110 can be located away from the center of the end of the device body 110. That is, there is a certain distance between the first and second ends of the device body 110. The distance between the first and second ends of the device body 110 can be greater than twice the diameter of the cross-section of the target. The cross-section can be a section parallel to the plane of rotation of the long arm 120 when the device is attached to the target. Taking a power cable as an example, the cross-section of the cable is usually approximately circular. The distance between the first end of the long arm 120 and the first end of the short arm 130 can be greater than twice the diameter of the cable's cross-section. This ensures that when the power cable is crimped onto the device body 110, the long arm 120 and the short arm 130 are in a nearly horizontal state. Here, "horizontal state" can mean that the straight line between the first and second ends of the long arm 120 is nearly horizontal, or the straight line between the first and second ends of the short arm 130 is nearly horizontal.

[0096] The distance between the first and second ends of the support arm 140 can be greater than the distance between the first and second sides of the end of the device body 110. This means that when the support arm 140 is in the state of being attached to the long arm 120 or the short arm 130, the opening in the middle area of ​​the long arm 120 and the short arm 130 is greater than the distance between the first end of the long arm 120 and the first end of the short arm 130.

[0097] In the above implementation process, by designing that the distance between the first and second sides of the end of the device body 110 is greater than twice the diameter of the cross-section of the target, the long arm 120 and the short arm 130 can be in a nearly horizontal state when the power cable is crimped onto the device body 110, thereby further improving the stability of the hanging device 100 when it is attached to the target. Furthermore, by ensuring that the distance between the first and second ends of the support arm 140 is greater than the distance between the first and second sides of the end of the device body 110, the opening in the middle region of the long arm 120 and the short arm 130 is enlarged. This further facilitates the target entering the middle region of the long arm 120 and the short arm 130 through this opening during the hanging process, ultimately further increasing the probability of successful hanging.

[0098] In some alternative implementations, the mounting target may include a power cable. Accordingly, the device body 110 may specifically be an equipotential bonding indicator. When the mounting device 100 is mounted on a power cable, the equipotential bonding indicator displays an indication of the energization status of the corresponding cable.

[0099] In the above implementation process, by using the hanging device 100 provided in the various embodiments of this application to hang power cables, the smoothness of hanging power cables and the stability when hanging power cables are improved, thereby reducing the risk to operators when performing power-related operations, reducing the probability of damage caused by equipment falling from a height, and thus avoiding safety accidents.

[0100] Please refer to Figure 4 , Figure 4 The embodiments provided in this application are related to Figure 2 A schematic diagram of the mounting system 10 from the same perspective. Based on the same concept, embodiments of this application provide a mounting system 10, which may include a receiving mechanism 200 and the mounting device 100 described above.

[0101] The receiving mechanism 200 may include a housing. The housing may form a receiving space with an opening. Exemplarily, the receiving mechanism 200 may be barrel-shaped. The receiving space may be used to receive the device body 110 of the attaching device 100, and the opening may be allowed for the attaching device 100 to enter and exit the receiving space.

[0102] During application, equipotentially charged displays, surveillance cameras, etc., can be placed into the receiving space through the opening. Following the process described above, the mounting system 10 is brought close to the mounting target until the support arm 140 is triggered, disengaging from the long arm 120 or short arm 130 and successfully mounting onto the target.

[0103] The above implementation process is the same as that of the hanging device 100 described above, and will not be repeated here.

[0104] Please continue to refer to Figure 4 In some optional embodiments, the receiving mechanism 200 may include an image acquisition device 300, such as a camera. The image acquisition device 300 may be disposed on the outside of the housing of the receiving mechanism 200. The angle between the field of view of the image acquisition device 300 and the orientation of the opening may be an acute angle, and the field of view of the image acquisition device 300 may include the orientation of the opening. That is, the image acquisition device 300 can acquire images of the long arm 120, the short arm 130, and the support arm 140 in real time and provide feedback to the user. This allows the user to adjust their operation based on the real-time images acquired by the image acquisition device 300 during the process of attaching the mounting system 10 to the mounting target.

[0105] In the above implementation process, by configuring an image acquisition device 300 on the mounting system 10, it is convenient for users to adjust the operation according to the image acquired by the image acquisition device 300, thereby improving the convenience of the mounting system 10 in the mounting process.

[0106] Please refer to Figure 5 , Figure 5 This is a first flowchart of the splicing method provided in the embodiments of this application. Based on the same concept, the embodiments of this application provide a splicing method that should be used in a splicing system.

[0107] The mounting system may include a receiving mechanism and a mounting device. The mounting device may include a device body, a long arm, a short arm, and a support arm. The specific structure of the mounting system may be the same as that of the mounting system 10 described in the previous embodiment.

[0108] The attachment method provided in this application embodiment may include:

[0109] Step S120: Move the attachment system closer to the attachment target and use the support arm to abut the attachment target.

[0110] In step S120 above, the mounting system can be moved closer to the target manually using tools such as support poles, or it can be moved closer to the target using automated equipment such as drones. During the process of moving the mounting system closer to the target, the direction of movement can be vertical or tilted upwards. That is, the target can be located at a high position. For example, power cables, the support frame of a surveillance camera, etc. During this process, the mounting device in the mounting system should be in a ready-to-mount state, that is, the support arm should be in contact with the long or short arm.

[0111] Step S140: Drive the attachment system to continue approaching the attachment target until the support arm disengages from the short or long arm.

[0112] In step S140 above, after the support arm of the attachment system abuts the attachment target, by controlling the attachment system to continue moving closer to the attachment target, the support arm will usually disengage from the abutment of the long arm or short arm under the abutment force of the attachment arm.

[0113] Step S160: With the long arm and short arm pressing and attaching to the target together, the receiving mechanism is driven back.

[0114] In step S160 above, after the support arm disengages from the long or short arm, the long and short arms swing toward the device body respectively, pressing the target onto the device body. The specific process can be the same as the operation of the attachment device described above. After successful attachment, when the receiving mechanism returns, it disengages from the attachment device, thus attaching the attachment device to the target while simultaneously retracting the receiving mechanism.

[0115] The above implementation process is the same as the previous described attachment system, and will not be repeated here.

[0116] Please refer to Figure 6, Figure 6 This is a second flowchart of the splicing method provided in this application embodiment. In some optional implementations, step S120 may include:

[0117] Step S121: The drone drives the attachment system to approach the attachment target and the support arm abuts against the attachment target.

[0118] Accordingly, step S140 may include:

[0119] Step S141: The drone drives the attachment system to continue approaching the attachment target until the support arm detaches from the short arm.

[0120] Accordingly, step S160 may include:

[0121] Step S161: The receiving mechanism is returned by the drone.

[0122] In the above steps, the housing mechanism can be detachably installed on the drone, for example, using components such as adapter plates and screws. During the process of attaching the system via the drone, the drone can be manually operated by the user, or the above steps can be programmed into the drone for automatic attachment.

[0123] In the aforementioned process, the use of drones to power the attachment system eliminates the need to replace support poles of varying lengths depending on the height of the target, thus significantly improving the flexibility of the attachment process compared to manual methods using poles. Furthermore, the drone-powered attachment system almost completely isolates users from direct or indirect physical contact with the attachment targets, such as power cables, thereby enhancing safety during the attachment process.

[0124] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
