Description

Technical Field

[0001] This application belongs to the field of lantern hanging technology, and in particular relates to a lantern hanging device. Background Technology

[0002] Lanterns are an ancient traditional handicraft. During holidays or major events, lanterns are hung on streetlights in many places to create an atmosphere. After a period of time, the lanterns need to be taken down and reinstalled for the next holiday.

[0003] Currently, in the process of hanging and retrieving lanterns, a long pole with a fork is sometimes used to move the lantern. Specifically, the lantern's hook is attached to the fork of the long pole, and the long pole is used to move the lantern to the vicinity of the hanging point, where the lantern's hook is then hung. During this process, the lantern's hook may slip off the fork, causing the lantern to fall to the ground and be damaged.

[0004] To prevent the lantern hooks from falling off, a gripping mechanism can be installed at the end of the long pole to stably hold the lantern hooks. However, since lantern hooks are usually quite thin (some lantern hooks may simply be made of thick wire bent into shape), they are prone to breakage or deformation under excessive pressure, which may affect the subsequent hanging of the lantern and make it difficult to grip the lantern hooks. Utility Model Content

[0005] The purpose of this application is to provide a lantern hanging device that can hang lanterns and reduce the risk of damage to the hook.

[0006] To achieve the above objectives, this application is implemented as follows: This application provides a lantern hanging device, including a device body, a rod, and a clamping mechanism. The clamping mechanism is located at the top of the rod and includes multiple grippers, each gripper having a return spring. The return spring is used to drive all grippers to close. The device body includes a housing, a drive device, and a traction rope. The housing is located at the bottom of the rod, and the main body of the drive device is fixed to the housing. The drive end of the drive device is connected to the bottom end of the traction rope, and the top end of the traction rope passes through the rod and is connected to each gripper. The drive device is used to drive the traction rope to pull the grippers and cause all grippers to open.

[0007] Optionally, the rod is a telescopic rod; the driving device is a motor; the main body of the device also includes a roller shaft, which is rotatably disposed in the housing, the main body of the motor is fixed on the housing, the drive shaft of the motor is coaxially connected to the roller shaft, and the bottom end of the traction rope is wound around the roller shaft.

[0008] Optionally, the drive device includes a plurality of traction ropes wound on the roller, the top ends of the plurality of traction ropes corresponding to and connected to a plurality of grippers.

[0009] Optionally, the rod body is provided with multiple corrugated tubes, each of which is fixed at both ends to the top and bottom of the rod body respectively; the multiple corrugated tubes correspond one-to-one with the multiple traction ropes, and the corrugated tubes are sleeved outside the corresponding traction ropes.

[0010] Optionally, the gripper includes a plurality of rotatably connected fingers, the bottom finger being the first finger, which is fixedly connected to the top end of the rod; the top finger being the second finger, the outer side of which is connected to the top end of the traction rope; a return spring is provided inside the gripper, with the two ends of the return spring connected to the first and second fingers respectively.

[0011] Optionally, a damper is provided between the knuckles of the gripper.

[0012] Optionally, the top end of the traction rope is connected to the outside of the second finger joint via a drive pulley set.

[0013] Optionally, the clamping mechanism includes at least three grippers, and the inner side of each gripper is provided with a silicone anti-slip pad.

[0014] Optionally, a camera is provided at the top of the rod, and a display is provided on the housing, with the display connected to the camera via a signal.

[0015] Optionally, a tension sensor is provided between the traction rope and the gripper.

[0016] Beneficial effects: In this embodiment, a return spring is provided inside or outside each gripper of the clamping mechanism. The return spring applies an elastic force to the gripper, so that the multiple grippers of the clamping mechanism can remain closed without being subjected to external force, thereby achieving the gripping of the hook. The traction rope is driven by the driving device to pull the gripper, so that the multiple grippers of the clamping mechanism open outward under the pulling force of the traction rope, thereby achieving the removal or insertion of the hook.

[0017] The lantern hook is gripped via a return spring, allowing the clamping mechanism to fit snugly against the surface of hooks of any size, thus enabling a relatively stable grip on hooks of different specifications. Simultaneously, it provides different gripping forces for hooks of varying thicknesses, preventing excessive compression and minimizing the risk of damage or deformation. Furthermore, by placing the drive device at the bottom of the device, the rod is prevented from being subjected to excessive weight pressure, maintaining a relatively straight position (avoiding bending under pressure). This facilitates a more stable hanging of the lantern by the clamping mechanism at the top of the rod, improving the efficiency and accuracy of the hanging operation.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The lantern-hanging device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] like Figure 1-3 As shown, this application embodiment provides a lantern hanging device, including a device body 1, a rod 2, and a clamping mechanism 3; the clamping mechanism 3 is disposed at the top end of the rod 2, and the clamping mechanism 3 includes multiple grippers 31, each gripper 31 is provided with a return spring 32, the return spring 32 is used to drive all grippers 31 to close; the device body 1 includes a housing 11, a driving device 12, and a traction rope 13, the housing 11 is disposed at the bottom end of the rod 2, the main body of the driving device 12 is fixed on the housing 11, the driving end of the driving device 12 is connected to the bottom end of the traction rope 13, the top end of the traction rope 13 passes through the rod 2 and is connected to each gripper 31, the driving device 12 is used to drive the traction rope 13 to pull the grippers 31 and drive all grippers 31 to open.

[0027] In this embodiment, the lantern hook is gripped by the clamping mechanism 3, and then the entire device is moved so that the rod 2 can carry the clamping mechanism 3 to hang the lantern hook at a high place, or so that the rod 2 can carry the clamping mechanism 3 to remove the lantern hanging at a high place.

[0028] Since lantern hooks are typically thin (some may simply be bent wire), they are prone to breakage or deformation under excessive pressure. Therefore, in this embodiment, the hook is gripped primarily through the return spring 32 of the clamping mechanism 3. Specifically, return springs 32 are installed inside or outside each gripper 31 of the clamping mechanism 3. The return springs 32 apply elastic force to the grippers 31, ensuring that the multiple grippers 31 of the clamping mechanism 3 remain closed without external force, thus gripping the hook. Under the elastic force of the return spring 32, the clamping mechanism 3 can fit tightly against the surface of hooks of any size, thus enabling relatively stable gripping of hooks of different sizes. Furthermore, the gripping force applied by the clamping mechanism 3 to the hook is mainly provided by the elastic force of the return spring 32. Therefore, the clamping mechanism 3 mainly applies elastic compressive force to the hook. When the hook is thicker, the closing degree of the clamping mechanism 3 is smaller, and the elastic force applied by the return spring 32 is larger, providing a greater gripping force. When the hook is thinner, the closing degree of the clamping mechanism 3 is larger, and the elastic force applied by the return spring 32 is smaller, providing a smaller gripping force. Thus, different gripping forces can be provided for hooks of different thicknesses, so that the hook will not be excessively compressed, and it is not easy to damage or deform the hook.

[0029] Based on this, in this embodiment, the driving device 12 drives the traction rope 13 to pull the gripper 31, so that the multiple grippers 31 of the clamping mechanism 3 open outward under the action of the traction rope 13, thereby realizing the removal or insertion of the hook. Specifically, the relatively heavy drive device 12 is installed inside the housing 11 of the main body 1 and located at the bottom of the rod 2. This concentrates the weight at the bottom of the device, preventing the rod 2 from being squeezed by excessive weight and keeping it relatively straight (avoiding the rod 2 from bending under the pressure of heavy objects). This facilitates the clamping mechanism 3 at the top of the rod 2 to hang the lantern more stably, improving the efficiency and accuracy of the hanging operation. The rod 2 has a hollow structure, and the traction rope 13 passes through the rod 2. When the multiple grippers 31 of the clamping mechanism 3 need to open, the drive end of the drive device 12 applies a pulling force to the bottom end of the traction rope 13, which in turn applies a pulling force to the top end of the traction rope 13 on the multiple grippers 31 of the clamping mechanism 3. When the applied pulling force exceeds the elastic force applied by the return spring 32, the multiple grippers 31 of the clamping mechanism 3 open outward.

[0030] In summary, this embodiment uses the return spring 32 to grip the lantern hook, allowing the clamping mechanism 3 to fit tightly against the surface of hooks of any size, thus enabling a relatively stable grip on hooks of different sizes. Simultaneously, it provides different gripping forces for hooks of different thicknesses, preventing excessive compression and minimizing the risk of damage or deformation. Furthermore, by placing the drive device 12 at the bottom of the device, the rod 2 is not subjected to excessive weight pressure, maintaining a relatively straight position (avoiding bending of the rod 2 under pressure). This facilitates a more stable hanging of the lantern by the clamping mechanism 3 at the top of the rod 2, improving the efficiency and accuracy of the hanging operation.

[0031] Optionally, the drive device 12 can be a cylinder or a motor. When the drive device 12 is a cylinder, the extension and retraction of the cylinder output end drives the traction rope 13 to apply tension to the gripper 31; when the drive device 12 is a motor, the rotation of the motor output end drives the traction rope 13 to apply tension to the gripper 31.

[0032] Optionally, the number of traction ropes 13 can be one or multiple. When there is one traction rope 13, the top of the traction rope 13 can form multiple branch ropes, and the multiple branch ropes correspond one-to-one with and are connected to multiple grippers 31; when there are multiple traction ropes 13, the bottom ends of the multiple traction ropes 13 are simultaneously connected to the drive end of the drive device 12, and the top ends of the multiple traction ropes 13 correspond one-to-one with and are connected to multiple grippers 31.

[0033] Optionally, the housing 11 has a handle 15, which makes it convenient for operators to hold the device for operation. The housing 11 can be equipped with a control switch for the drive device 12, which allows operators to control the drive device 12 to close or open the clamping mechanism 3.

[0034] In some embodiments, a camera 4 is provided at the top of the rod 2, and a display 16 is provided on the housing 11, the display 16 being signal-connected to the camera 4.

[0035] In this embodiment, the camera 4 at the top of the rod 2 transmits the working image of the clamping mechanism 3 back to the display 16 in real time, so that the staff can observe the working process and make fine adjustments.

[0036] Optionally, an angle sensor can also be installed inside the housing 11. The angle sensor can collect the gripping angle of the device and determine the timing of closing or opening the clamping mechanism 3 based on the gripping angle. For example, if the device is laid flat, it means that the lantern hook needs to be removed from or hung on the clamping mechanism 3 at a low position, and the clamping mechanism 3 can be opened naturally at this time. On the other hand, if the device is tilted upward, it means that the clamping mechanism 3 needs to grab the hook and move the lantern, and the clamping mechanism 3 can be closed naturally at this time, thereby improving the convenience of operation.

[0037] In some embodiments, a tension sensor is provided between the traction rope 13 and the gripper 31.

[0038] In this embodiment, the tension applied by the traction rope 13 to the gripper 31 is monitored in real time by a tension sensor to avoid excessive tension on the gripper 31 and damage to the gripper 31.

[0039] Optionally, a buzzer can be installed inside the housing 11. The buzzer is connected to the tension sensor signal. When the tension detected by the tension sensor exceeds the threshold, the buzzer sounds an alarm to inform the operator of the risk.

[0040] Optionally, a power module 17 and a microcontroller can also be installed inside the housing 11. The buzzer, tension sensor, angle sensor, display 16, and camera 4 are all connected to the microcontroller. The display 16 can simultaneously display the image captured by the camera 4, the power level of the power module 17, the angle, and other visual information.

[0041] In some embodiments, the rod 2 is a telescopic rod.

[0042] In this embodiment, the rod 2 is an adjustable telescopic rod, which facilitates hanging lanterns of different heights and also makes it easy to store the device. The length of the telescopic rod can range from 1.5m to 5m.

[0043] Optionally, the telescopic rod can be a rod formed by sequentially fitting multiple sleeves, and its telescopic movement can be adjusted electrically or manually. The number of sleeves can be three: an outer sleeve, a middle sleeve, and an inner sleeve, sequentially fitted from the outside in. The outer diameter of the outer sleeve can be 5cm, the outer diameter of the middle sleeve can be 4cm, and the outer diameter of the inner sleeve can be 3cm. The top end of the inner sleeve can be connected to the base of the clamping mechanism 3.

[0044] Optionally, the telescopic pole can be made of carbon fiber and has a load-bearing capacity of 15kg.

[0045] Optionally, when the telescopic rod is a manually telescopic rod, the adjacent hollow tubes can be fixed after telescopic movement by means of a spring plunger structure or a pin.

[0046] In some embodiments, the driving device 12 is a motor; the main body 1 of the device also includes a roller 14, which is rotatably disposed in the housing 11, the main body of the motor is fixed on the housing 11, the drive shaft of the motor is coaxially connected to the roller 14, and the bottom end of the traction rope 13 is wound around the roller 14.

[0047] In this embodiment, to enable the traction rope 13 to adapt to changes in the length of the telescopic rod, the drive device 12 is configured as a motor, and a roller 14 is installed between the bottom end of the traction rope 13 and the motor. When the telescopic rod shortens, the motor drives the roller 14 to rotate, allowing the excess length of the traction rope 13 to be retracted onto the roller 14. During this process, the return spring 32 in the gripper 31 applies an elastic tension to the traction rope 13, assisting in the tensioning of the traction rope 13, so that the traction rope 13 can be wound back onto the roller 14 in a relatively tight state. When the telescopic rod extends, the roller 14 releases the corresponding length of the traction rope 13, at which point the motor reverses.

[0048] In some embodiments, the drive device includes a plurality of traction ropes 13 wound on the roller 14, the top ends of the plurality of traction ropes 13 corresponding to and connected to a plurality of grippers 31.

[0049] In this embodiment, the number of traction ropes 13 is the same as the number of grippers 31, each traction rope 13 corresponds to one gripper 31, and the corresponding traction ropes 13 and grippers 31 are connected together.

[0050] Optionally, the main body 1 of the device includes multiple motors, each motor has a roller 14 connected to its output end, a traction rope 13 is wound on each roller 14, and each traction rope 13 is connected to a gripper 31. By using different motors and rollers 14 to individually store or release different traction ropes 13, the error caused by the change in the length of the traction rope 13 can be minimized, thereby improving the synchronization of all grippers 31 when they open.

[0051] Alternatively, the main body 1 of the device may include a motor, and the bottom ends of multiple traction ropes 13 may be simultaneously wound around the same roller 14. As the roller 14 rotates, the ropes are simultaneously wound or released, reducing the number of motors and rollers 14 in the device, reducing the weight of the device, and making it easier for operators to handle.

[0052] In some embodiments, the rod body 2 is provided with a plurality of corrugated tubes 21, and the two ends of each corrugated tube 21 are respectively fixed to the top and bottom ends of the rod body 2; the plurality of corrugated tubes 21 correspond one-to-one with the plurality of traction ropes 13, and the corrugated tube 21 is sleeved on the outside of the corresponding traction rope 13.

[0053] In this embodiment, the corrugated tube 21 guides the traction rope 13 inside, thereby improving the stability of the traction rope 13 during the application of tension.

[0054] When the rod 2 is a telescopic rod, since both ends of the corrugated tube 21 are fixed to the top and bottom of the rod 2 respectively, the corrugated tube 21 can extend and retract synchronously with the telescopic rod. The corrugated tube 21 guides the traction rope 13 inside, which can prevent multiple traction ropes 13 from getting tangled together inside the telescopic rod due to the swaying of the traction rope 13 when it is being stored or released, thus avoiding the situation where the traction rope 13 gets tangled together inside the telescopic rod, affecting the use of the device.

[0055] Optionally, the material of the corrugated pipe 21 may include PVC.

[0056] In some embodiments, the gripper 31 includes a plurality of rotatably connected fingers in sequence. The bottom finger is the first finger 311, which is fixedly connected to the top end of the rod 2. The top finger is the second finger 312, and the outer side of the top finger is connected to the top end of the traction rope 13. The gripper 31 is provided with a return spring 32, and the two ends of the return spring 32 are respectively connected to the first finger 311 and the second finger 312.

[0057] In this embodiment, when the gripper 31 grasps the lantern hook, the multiple joints of the gripper 31 will be subjected to the elastic force of the return spring 32 and the supporting force applied by the hook to the joints, causing the gripper 31 to form a bent posture that adapts to the hook surface. At this time, the inner surface of the multiple joints of the gripper 31 can be closely attached to the hook surface, improving the stability when grasping the hook.

[0058] Each gripper 31 may have only one return spring 32. The two ends of the return spring 32 can be connected to the first phalanx 311 and the second phalanx 312, respectively. By pulling the bottom phalanx (i.e., the first phalanx 311) and the top phalanx (i.e., the second phalanx 312) with the return spring 32, the gripper 31 naturally bends inward, thus closing the gripping mechanism 3. In this case, the return spring 32 is preferably located inside the gripper 31, and is covered by the outer shell of the gripper 31. This prevents part of the surface of the return spring 32 from being exposed on the inside of the gripper 31 when the gripper 31 is in a bent position, so that the return spring 32 preferentially contacts the hook and affects the gripper 31's gripping of the hook.

[0059] Optionally, the return spring 32 can be a disc spring.

[0060] Optionally, the gripper 31 may include three rotatably connected knuckles in sequence; further, two adjacent knuckles may be hinged by a pin, and each knuckle may independently achieve a bending degree of ±45° based on the adjacent knuckles. The three knuckles can work together to form an adaptive angle range of 0-180°; further, the pin may be made of titanium alloy material with a diameter of 3mm.

[0061] In addition, each gripper 31 may also have multiple return springs 32, with one return spring 32 between every two adjacent phalanges. The pull of the return springs 32 causes any two adjacent phalanges to tend to bend inward.

[0062] Optionally, the return spring 32 can be a torsion spring.

[0063] In some embodiments, a damper 33 is provided between the knuckles of the gripper 31.

[0064] In this embodiment, by setting the damper 33, the impact force of the gripper 31 when closing can be reduced, so that the compression increases linearly (rather than abruptly), further reducing the risk of damage or deformation to the hook; and by setting the damper 33, the impact force of the gripper 31 when opening can be reduced, thereby improving the service life of the gripper 31.

[0065] Optionally, the damper 33 may be a spring damper 33, and the diameter of the spring damper 33 may be 1.5 mm.

[0066] In some embodiments, the top end of the traction rope 13 is connected to the outer side of the second finger joint 312 via a transmission wheel assembly.

[0067] In this embodiment, by setting up the transmission wheel set, the top end of the traction rope 13 is guided to extend outward from the top end of the rod 2 and connected to the outside of the second finger joint 312, thereby improving the transmission continuity of the traction rope 13 applying tension to the gripper 31.

[0068] Optionally, the transmission wheel assembly may include guide wheels 5 disposed on the inner and outer sides of the top of the rod 2 and on the outer sides of each finger joint, and guide the change of direction of the traction rope 13 through multiple guide wheels 5.

[0069] Optionally, the transmission wheel assembly may further include a movable pulley 6, which is connected to the outside of the first finger joint 311. The top end of the traction rope 13 passes around the movable pulley 6 from the outside to the inside and is connected near the bottom of the gripper 31. By setting the movable pulley 6, the driving force of the drive device 12 to drive the gripper 31 to open is reduced.

[0070] Optionally, when the surface of the traction rope 13 is relatively smooth, the traction rope 13 can be exposed. In this case, the traction rope 13 is unlikely to scratch the lantern, and can serve to separate the clamping mechanism 3 from the lantern, thus preventing the clamping mechanism 3 from scratching the lantern.

[0071] Optionally, when the surface of the traction rope 13 is relatively rough, a flexible pad can be wrapped around the outside of each clamp 31 to prevent the traction rope 13 from rubbing against the lantern, thereby preventing the traction rope 13 from scratching the lantern.

[0072] In some embodiments, the clamping mechanism 3 includes at least three grippers 31, and the inner side of each gripper 31 is provided with a silicone anti-slip pad 313.

[0073] In this embodiment, the hook is gripped by at least three grippers 31, forming a stable surrounding structure. The hook is less likely to slip or rotate among the at least three grippers 31, making the grip more reliable. The silicone anti-slip pad 313 is elastic and can conform to the small irregular surface of the hook, increasing the contact area and friction, adapting to hooks of different shapes or sizes, and improving the grip's firmness. At the same time, the silicone also provides a certain degree of cushioning and protection, further reducing the risk of damage or deformation to the hook.

[0074] Optionally, a 0.5mm thick silicone pad can be embedded in the inner surface of the gripper 31 that contacts the hook. The surface of the pad is engraved with micron-level textures, which not only enhances friction but also avoids damage or deformation of the hook caused by rigid compression through flexible contact.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
