Description

Technical Field

[0001] This utility model relates to the field of locks, and more specifically, to an electrically controlled anti-climbing pole tower lock. Background Technology

[0002] Currently, to prevent unauthorized personnel from climbing utility poles or towers used in power systems, communication systems, etc., anti-climb pole locks are commonly installed on the poles. When locked, these locks create a physical barrier by unfolding the internal support components, effectively preventing climbing and ensuring facility and public safety. However, current anti-climb pole locks cannot achieve perfect coaxiality between the fixed and moving parts during installation. In addition, there may be angular errors in the installation of the lock pole, which often leads to jamming when unlocking the anti-climb pole lock.

[0003] Furthermore, most existing anti-climb pole locks employ purely mechanical structures, relying on dedicated physical keys (such as the E40 key) for opening and closing. Authorized operators must carry the matching key to the site and manually unlock the lock to perform pole climbing operations. While this method provides a certain level of safety protection, it still has the following significant drawbacks:

[0004] 1. Existing locks only support mechanical key unlocking, which is a single function. Operators must carry a special key with them at all times. If the key is lost, damaged, or not carried, it will be impossible to unlock in time, which will seriously affect the efficiency of emergency maintenance. At the same time, the management and distribution of keys are also inconvenient and increase the operation and maintenance management costs.

[0005] 2. Pole climbing is inherently a high-altitude operation with high risks. Before climbing, workers need to laboriously operate the unlocking mechanism from below the pole. Especially at night, in bad weather, or when handling emergency malfunctions, the inconvenience of operation not only increases the labor intensity but also prolongs the time exposed to the dangerous environment, which may bring secondary safety hazards.

[0006] 3. Traditional mechanical locks cannot record information such as unlocking time, lack effective security audit and traceability mechanisms, and managers cannot remotely monitor the status of locks (such as whether they have been opened abnormally), making it difficult to achieve intelligent and refined asset security management.

[0007] With the development of IoT technology and the increasing demand for intelligent management of power and communication networks, the industry urgently needs a new type of anti-climb pole lock. Therefore, it is necessary to propose an electronically controlled anti-climb pole lock that solves the above problems. Utility Model Content

[0008] To overcome at least one of the defects (deficiencies) of the prior art, this utility model provides an electrically controlled anti-climbing pole lock.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: an electrically controlled anti-climbing pole tower lock, comprising a fixed part, a support assembly, a movable part, a lock body, a lock rod, an electrically controlled unlocking device, and a mechanical unlocking device;

[0010] The fixed part is fixedly mounted on the anti-climb pole, the movable part is movably mounted on the anti-climb pole, and the spreading component is disposed between the fixed part and the movable part. When the spreading component is spread open, the movable part moves toward the fixed part. When the spreading component is closed, the movable part moves away from the fixed part.

[0011] The fixed part is provided with a positioning seat, the movable part is provided with a connecting hole, the locking rod is provided with a swingable fulcrum joint, the locking rod is set on the positioning seat through the fulcrum joint, and the other end of the locking rod passes through the connecting hole;

[0012] The locking bar has a locking position, and the lock body has a retractable locking tongue. When the locking tongue and the locking bar are locked together, the front end of the locking tongue is locked in the locking position of the locking bar, and the end of the locking tongue abuts against the electric unlocking device and the mechanical unlocking device respectively. Since the locking bar has a swingable fulcrum joint, the fulcrum joint can swing freely within a certain range. When the movable part is pulled up and down, it can automatically adapt to the installation error between the fixed part and the movable part, making unlocking smoother. In addition, since the end of the locking tongue abuts against the electric unlocking device and the mechanical unlocking device respectively, the operator can remotely unlock the tower lock through the electric control after climbing. This facilitates the operation of the operator and also makes it easy for the control center to record the unlocking status and unlocking time of the electric anti-climb tower lock.

[0013] Furthermore, the lock body includes a lock body mounting shell, a lock tongue positioning pin, a return spring, an unlocking button, an unlocking spring, an unlocking retaining ring, and a reed switch pin;

[0014] The lock rod is provided with an unlock button slot, and the unlock ring can move back and forth on the unlock button slot. One end of the unlock ring is connected to the unlock button, and the other end is set on the lock body mounting shell through an unlock spring.

[0015] The lock body mounting shell is provided with a lock rod through hole for the lock rod to pass through, and the side end of the lock rod through hole is provided with a locking communication hole;

[0016] The latch has a slotted hole, and one end of the latch positioning pin is set on the lock body mounting shell, while the other end passes through the slotted hole on the latch.

[0017] The latch is provided with a latch protruding end that is connected to the locking position, and the return spring is sleeved on the latch between the latch protruding end and the latch positioning pin;

[0018] The locking tongue has a beveled arc-shaped groove at its end, which matches a reed switch pin. Under the control of both the electronic and mechanical unlocking devices, the reed switch pin is vertically adjustable at the end of the locking tongue. When the reed switch pin rises, the locking tongue, under the action of the return spring, separates its protruding end from the locking rod. When the reed switch pin descends, it pushes the locking tongue outward, causing its protruding end to pass through the locking hole and lock into the locking position on the locking rod. Through the design of the unlocking button, unlocking spring, and unlocking ring, unlocking the locking rod only requires pressing the unlocking button to compress the unlocking spring and release the unlocking ring. The ring separates from the unlocking button slot on the lock bar, thereby unlocking the lock bar. Since the lock bar is engaged by both the bolt and the unlocking ring when locked, the occurrence of misoperation can be effectively reduced. In addition, since there is a beveled arc groove at the end of the bolt, when the lock bar needs to be relocked, the reed pin will move down again under the control of the electric or mechanical unlocking device and engage in the beveled arc groove. Therefore, the beveled arc groove facilitates the downward movement of the reed pin, so that the reed pin abuts against the end of the bolt and engages the protruding end of the bolt in the lock bar engagement position.

[0019] Furthermore, the mechanical unlocker includes a lock cylinder, an unlocking pin, a locking shaft, an unlocking pin return spring, and an unlocking pin positioning shaft;

[0020] The unlocking pin is provided with an unlocking strip-shaped movable hole, and the unlocking pin positioning shaft passes through the unlocking strip-shaped movable hole on the unlocking pin and is fixed on the lock body mounting shell;

[0021] The lock cylinder is mounted on the lock body housing. Both the end of the locking shaft and the beginning of the unlocking pin are beveled. The beginning of the locking shaft is connected to the lock cylinder, and the end of the locking shaft presses against the beveled end of the unlocking pin. The end of the unlocking pin is connected to a reed switch pin. A return spring is sleeved on the end of the unlocking pin. When unlocking the electrically controlled anti-climbing pole lock, simply insert the key into the lock cylinder and rotate it. Since the locking shaft is connected to the lock cylinder, it rotates synchronously. Because both the end of the locking shaft and the beginning of the unlocking pin are beveled, the rotation of the locking shaft pushes the unlocking pin upwards, causing it to lift the reed switch pin, thus unlocking the bolt.

[0022] Furthermore, the inclined surfaces of the locking shaft and the unlocking pin are provided with horizontal support surfaces. By providing horizontal support surfaces on the inclined surfaces of the locking shaft and the unlocking pin, after the locking shaft rotates to its position, the locking shaft can be supported by the horizontal support surfaces on the locking shaft and the unlocking pin, thereby enabling better control of lifting and pulling the reed switch pin.

[0023] Furthermore, the electronically controlled unlocker includes a switch, a signal interface, a control circuit board, a controller, and electronically controlled components for interconnecting with the reed switch pin.

[0024] The control circuit board is housed inside the lock body mounting shell, and the switches, signal interfaces, and electronic control components are respectively connected to the control circuit board;

[0025] The controller is connected to the signal interface. Since the switch, signal interface, and electronic control components are all connected to the control circuit board, when the lock bar needs to be unlocked, the operator can press the switch on the control circuit board. At this time, the controller connected to the control circuit board will start wireless broadcasting and send the operator's unlocking request to the control center. After the control center remotely authorizes unlocking, the electronic control components control the reed switch pin to rise, and the lock tongue moves into the lock body under the action of the return spring. The protruding end of the lock tongue separates from the lock bar, thereby realizing unlocking.

[0026] Furthermore, it also includes reed switches and magnets;

[0027] The reed switch is connected to the control circuit board, and the magnet is set on the latch. When the latch moves into position, the magnet on the latch and the reed switch sense each other. By sensing the position of the magnet on the latch through the reed switch on the control circuit board, the current locking status of the electric anti-climb pole tower lock can be quickly determined, which is convenient for remote monitoring by the control center.

[0028] Furthermore, the controller is equipped with wireless broadcast transmitting and receiving modules. The wireless broadcast transmitting module can transmit the real-time status of the electrically controlled anti-climb pole lock and the unlocking request from the operator to the control center, while the wireless broadcast receiving module can receive the instructions sent by the control center, which facilitates the control of the electrically controlled anti-climb pole lock to perform unlocking or locking operations.

[0029] Furthermore, the controller is provided with a hook fixing plate. The controller is mounted on the fixed part or the movable part through the hook fixing plate. The hook fixing plate makes it easy to fix the controller on the fixed part or the movable part, which is simple and practical.

[0030] Furthermore, the fulcrum joint includes a swing rod, a swing positioning pin, and a joint connecting ball disposed on the positioning seat;

[0031] The locking rod is provided with a positioning pin hole;

[0032] One end of the swing rod is connected to the joint connecting ball, and the other end is locked in the positioning pin hole of the lock rod by a swing positioning pin. With the swing rod, swing positioning pin and joint connecting ball, the joint connecting ball and the swing rod on the lock rod can swing freely within a certain range after the lock rod is installed. Therefore, when the movable part is pulled up and down, the joint connecting ball on the lock rod can automatically adapt to the installation error between the fixed part and the movable part, making unlocking smoother.

[0033] Furthermore, the spreading assembly includes multiple sets of extension rods and support rods;

[0034] The first end of the extension rod is hinged to the fixed part, the first end of the support rod is hinged to the movable part, and the end of the support rod is hinged to the middle of the extension rod.

[0035] The end of the extension rod is equipped with a linkage ring. By setting up multiple sets of extension rods and support rods, the extension rods and support rods can easily form a physical obstacle after being extended, thereby effectively preventing climbing and ensuring facility safety and public safety. In actual use, linkage ropes can be tied between adjacent linkage rings to facilitate the synchronous deployment of multiple sets of extension rods and support rods.

[0036] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0037] The electrically controlled anti-climb pole tower lock disclosed in this utility model has a swingable fulcrum joint on the lock rod. Therefore, the fulcrum joint can swing freely within a certain range. When the movable part is pulled up and down, it can automatically adapt to the installation error between the fixed part and the movable part, making the unlocking smoother. In addition, since the end of the lock tongue abuts against the electric unlocking device and the mechanical unlocking device respectively, the operator can remotely unlock the pole after climbing. This facilitates the operator's work and also makes it easier for the control center to record the unlocking status and unlocking time of the electrically controlled anti-climb pole tower lock.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0049] like Figure 1-2 As shown, an electrically controlled anti-climb pole tower lock includes a fixed part 1, a spreading assembly 2, a movable part 3, a lock body 4, a locking rod 5, an electrically controlled unlocking device 6, and a mechanical unlocking device 7. The fixed part 1 is fixedly mounted on the anti-climb pole 8, the movable part 3 is movably mounted on the anti-climb pole 8, and the spreading assembly 2 is positioned between the fixed part 1 and the movable part 3. When the spreading assembly 2 is spread open, the movable part 3 moves towards the fixed part 1; when the spreading assembly 2 is closed, the movable part 3 moves away from the fixed part 1. The fixed part 1 is provided with a positioning seat 9, the movable part 3 is provided with a connecting hole 10, and the locking rod 5 is provided with a swingable fulcrum joint 12. The locking rod 5 is mounted on the positioning seat 9 through the fulcrum joint 12, and the other end of the locking rod 5 passes through the connecting hole 10. The locking rod 5 is provided with a locking position 11, and the lock body 4 contains... The device is equipped with a retractable locking tongue 13. When the locking tongue 13 is locked to the locking rod 5, the front end of the locking tongue 13 is engaged in the locking position 11 of the locking rod 5, and the end of the locking tongue 13 abuts against the electric unlocking device 6 and the mechanical unlocking device 7 respectively. Since the locking rod 5 is equipped with a swingable fulcrum joint 12, the fulcrum joint 12 can swing freely within a certain range. When the movable part 3 is pulled up and down, it can automatically adapt to the installation error between the fixed part 1 and the movable part 3, making unlocking smoother. In addition, since the end of the locking tongue 13 abuts against the electric unlocking device 6 and the mechanical unlocking device 7 respectively, the operator can remotely unlock the device through the electric control after climbing. This facilitates the operation of the operator and also makes it easier for the control center to record the unlocking status and unlocking time of the electric anti-climb pole tower lock.

[0050] like Figure 3-4As shown, the lock body 4 includes a lock body mounting shell 14, a bolt positioning pin 15, a return spring 16, an unlock button 17, an unlock spring 18, an unlock ring 19, and a reed switch pin 20; the lock rod 5 is provided with an unlock button groove 21, and the unlock ring 19 can move back and forth on the unlock button groove 21. One end of the unlock ring 19 is connected to the unlock button 17, and the other end is set on the lock body mounting shell 14 through the unlock spring 18; the lock body mounting shell 14 is provided with a lock rod through hole 22 for the lock rod 5 to pass through, and the side end of the lock rod through hole 22 is provided with a locking communication hole 23; the bolt 13 is provided with a strip hole 24. One end of the latch positioning pin 15 is set on the lock body mounting shell 14, and the other end passes through the strip hole 24 on the latch 13. The latch 13 has a latch protruding end 25 connected to the locking position 11. The return spring 16 is sleeved on the latch 13 between the latch protruding end 25 and the latch positioning pin 15. The end of the latch 13 has an arc-shaped groove 27 with a bevel 26. The arc-shaped groove 27 with a bevel 26 matches the reed switch iron pin 20. Under the control of the electric unlocking device 6 and the mechanical unlocking device 7, the reed switch iron pin 20 can be raised and lowered at the end of the latch 13. When the reed switch iron pin 20 is raised, the latch... 13. Under the action of the return spring 16, the protruding end 25 of the latch separates from the locking rod 5. When the reed switch pin 20 descends, the reed switch pin 20 pushes the latch 13 outward, so that the protruding end 25 of the latch passes through the locking hole 23 and is locked in the locking position 11 of the locking rod 5. With the setting of the unlocking button 17, the unlocking spring 18 and the unlocking ring 19, when unlocking the locking rod 5, it is only necessary to press the unlocking button 17 to compress the unlocking spring 18, and the unlocking ring 19 separates from the unlocking button groove 21 on the locking rod 5, thereby realizing the unlocking of the locking rod 5. Since the locking rod 5 is locked at the same time through the latch 13 and The locking ring 19 is used to lock the bolt, which can effectively reduce the occurrence of misoperation. In addition, since the end of the bolt 13 is provided with an arc groove 27 with a bevel 26, when the locking rod 5 needs to be relocked, the reed pin 20 will move down again under the control of the electric unlocker 6 or the mechanical unlocker 7 and lock onto the arc groove 27 with the bevel 26. Therefore, the arc groove 27 with the bevel 26 can facilitate the downward movement of the reed pin 20, so that the reed pin 20 abuts against the end of the bolt 13 and the protruding end 25 of the bolt is locked onto the locking position 11 of the locking rod 5.

[0051] like Figure 5As shown, the mechanical unlocking device 7 includes a lock cylinder 28, an unlocking pin 29, a locking shaft 30, an unlocking pin return spring 31, and an unlocking pin positioning shaft 32. The unlocking pin 29 has an unlocking strip-shaped movable hole 33. The unlocking pin positioning shaft 32 passes through the unlocking strip-shaped movable hole 33 on the unlocking pin 29 and is fixed to the lock body mounting shell 14. The lock cylinder 28 is mounted on the lock body mounting shell 14. The end of the locking shaft 30 and the beginning of the unlocking pin 29 are both beveled. The beginning of the locking shaft 30 is connected to the lock cylinder 28, and the end of the locking shaft 30 presses against the beveled end of the unlocking pin 29. The end of the unlocking pin 29 is connected to a reed switch pin 20. The unlocking pin return spring 31 is sleeved on the end of the unlocking pin 29. When it is necessary to unlock the electrically controlled anti-climbing pole tower lock, simply insert the key into the lock cylinder 28 and actuate the lock. When the lock cylinder 28 rotates, the locking shaft 30, which is connected to the lock cylinder 28, also rotates synchronously. Since the end of the locking shaft 30 and the beginning of the unlocking pin 29 are both inclined, the rotation of the locking shaft 30 pushes the unlocking pin 29 up, thereby causing the unlocking pin 29 to lift the reed switch pin 20 and unlock the bolt 13. A horizontal support surface 34 is provided on the inclined surfaces of the locking shaft 30 and the unlocking pin 29. Because of this horizontal support surface 34, after the locking shaft 30 rotates to its position, the locking shaft 30 can be supported by the horizontal support surface 34 on the locking shaft 30 and the horizontal support surface 34 on the unlocking pin 29, thus better controlling the lifting and lowering of the reed switch pin 20.

[0052] like Figure 6-7As shown, the electronic unlocking device 6 includes a switch 35, a signal interface 36, a control circuit board 37, a controller 38, and an electronic control component 39 for interconnection with the reed switch pin 20. The control circuit board 37 is located inside the lock body mounting housing 14. The switch 35, signal interface 36, and electronic control component 39 are respectively connected to the control circuit board 37. The controller 38 is connected to the signal interface 36. Since the switch 35, signal interface 36, and electronic control component 39 are respectively connected to the control circuit board 37, when it is necessary to unlock the lock lever 5, the operator can press the switch 35 on the control circuit board 37. At this time, the controller 38 connected to the control circuit board 37 activates wireless broadcasting to announce the operator's unlocking request. The request is sent to the control center. After remote authorization for unlocking, the control center controls the reed switch pin 20 to rise. The bolt 13 moves into the lock body 4 under the action of the return spring 16, and the protruding end 25 of the bolt separates from the lock rod 5 to achieve unlocking. In addition, it also includes a reed switch 40 and a magnet 41. The reed switch 40 is connected to the control circuit board 37, and the magnet 41 is set on the bolt 13. When the bolt 13 moves into position, the magnet 41 on the bolt 13 senses each other with the reed switch 40. By sensing the position of the magnet 41 on the bolt 13 through the reed switch 40 on the control circuit board 37, the current locking status of the electric anti-climb pole tower lock can be quickly determined, which is convenient for the control center to perform remote monitoring.

[0053] In this utility model, the controller 38 is equipped with a wireless broadcasting transmitter and a wireless broadcasting receiver module. The wireless broadcasting transmitter module can transmit the real-time status of the electrically controlled anti-climbing pole tower lock and the unlocking request from the operator to the control center. The wireless broadcasting receiver module can receive the instructions sent by the control center, which facilitates the control of the electrically controlled anti-climbing pole tower lock to perform unlocking or locking operations. In addition, the controller 38 is equipped with a hook fixing plate 42. The controller 38 is mounted on the fixed part 1 or the movable part 3 through the hook fixing plate 42. The hook fixing plate 42 makes it easy to fix the controller 38 on the fixed part 1 or the movable part 3, which is simple and practical.

[0054] like Figure 8 As shown, the fulcrum joint 12 includes a swing rod 43, a swing positioning pin 44, and a joint connecting ball 45 disposed on the positioning seat 9; the locking rod 5 is provided with a positioning pin hole 46; one end of the swing rod 43 is connected to the joint connecting ball 45, and the other end is locked in the positioning pin hole 46 of the locking rod 5 through the swing positioning pin 44. Due to the arrangement of the swing rod 43, the swing positioning pin 44, and the joint connecting ball 45, after the locking rod 5 is installed, the joint connecting ball 45 and the swing rod 43 on the locking rod 5 can swing freely within a certain range. Therefore, when the movable part 3 is pulled up and down, the joint connecting ball 45 on the locking rod 5 can automatically adapt to the installation error between the fixed part 1 and the movable part 3, making unlocking smoother.

[0055] In this utility model, the spreading component 2 includes multiple sets of extension rods 47 and support rods 48; the first end of the extension rod 47 is hinged to the fixed part 1, the first end of the support rod 48 is hinged to the movable part 3, and the end of the support rod 48 is hinged to the middle of the extension rod 47; the end of the extension rod 47 is provided with a linkage ring 49. By setting multiple sets of extension rods 47 and support rods 48, the extension rods 47 and support rods 48 can easily form a physical obstacle after being spread out, thereby effectively preventing climbing and ensuring facility safety and public safety. In actual use, linkage ropes can be tied between adjacent linkage rings 49 to facilitate the synchronous unfolding of multiple sets of extension rods 47 and support rods 48.

[0056] Example

[0057] In this embodiment, since the lock bar is provided with a swingable fulcrum joint, the fulcrum joint can swing freely within a certain range. When the movable part is pulled up and down, the fulcrum joint can automatically adapt to the installation error between the fixed part and the movable part, making the unlocking and the up and down movement of the movable part smoother.

[0058] In addition, when it is necessary to unlock the lock bar, the operator can choose the electronic unlocking method. In this case, the operator only needs to press the switch on the control circuit board. At this time, the controller connected to the control circuit board starts wireless broadcasting and sends the operator's unlocking request to the control center. After the control center remotely authorizes the unlocking, the electronic control components control the reed switch pin to rise, and the lock tongue moves into the lock body under the action of the return spring. The protruding end of the lock tongue separates from the lock bar, thereby realizing unlocking.

[0059] When mechanical unlocking is required using the E40 key, simply insert the key into the lock cylinder and rotate it. Since the locking shaft is connected to the lock cylinder, it also rotates synchronously. Because both the end of the locking shaft and the beginning of the unlocking pin are beveled, the rotation of the locking shaft will push the unlocking pin up, thereby causing the unlocking pin to lift the reed switch pin and unlock the bolt.

[0060] After the latch is unlocked, the operator only needs to press the unlock button to compress the unlock spring, and the unlocking ring separates from the unlock button slot on the lock bar, thus achieving secondary unlocking of the lock bar. Since the lock bar is locked simultaneously by the latch and the unlocking ring, the occurrence of misoperation can be effectively reduced. In addition, since there is a beveled arc groove at the end of the latch, when the lock bar needs to be relocked, the reed pin will move down again under the control of the electric unlocker or mechanical unlocker and lock into the beveled arc groove. Therefore, the beveled arc groove can facilitate the downward movement of the reed pin, so that the reed pin abuts against the end of the latch and locks the protruding end of the latch into the locking position of the lock bar.

[0061] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
