Description

Technical Field

[0001] This invention relates to the field of door lock removal technology, specifically a quick door lock removal tool. Background Technology

[0002] A door lock is a device installed on a door to open and close it mechanically or electronically, ensuring the security of the space. Its core consists of a lock cylinder, lock body, panel, handle, and key or identification module. The lock cylinder is the heart of the lock; its internal precision tumbler or leaf structure determines the uniqueness of the key. Traditional mechanical locks rely on the key's teeth aligning with the tumblers to rotate the lock cylinder and drive the bolt, while smart locks use electronic signals such as fingerprints, passwords, card swipes, or facial recognition to trigger a motor that moves the bolt. The lock body, as the actuator, contains the main bolt, latch, and deadbolt, which extend or retract under the drive of the lock cylinder or motor to engage with the door frame strike plate and complete the locking process. The panel covers the exterior of the lock body for decoration and protection, while the handle is used to manually open the latch. Modern door locks not only pursue physical protection levels against prying, drilling, and technical opening, but also gradually incorporate Internet of Things (IoT) technology to achieve remote monitoring and anomaly alarms, making them a security terminal that integrates precision mechanical manufacturing, materials science, and electronic information technology.

[0003] The existing demolition tools are power tools, which are quite heavy and require considerable effort from operators to hold, necessitating frequent breaks and impacting demolition efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a quick door lock removal tool to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a quick door lock removal tool, including a base, wherein a platform is provided on the top of the base; An adjustment mechanism is provided between the base and the platform. The adjustment mechanism includes a first fixing plate, which is fixedly connected to the top of the base. A first electric push rod is fixedly connected to the side of the first fixing plate. An abutment rod is fixedly connected to the side of the first electric push rod. An inclined block is fixedly connected to the bottom of the platform. The abutment rod contacts the inclined block. A telescopic rod is fixedly connected between the base and the platform. A dismantling device is provided on the top of the platform.

[0006] Preferably, a second fixing plate is fixedly connected to the side of the base, a second electric push rod is fixedly connected to the bottom of the second fixing plate, a ring plate is fixedly connected to the bottom of the second electric push rod, and a suction cup is fixedly connected to the bottom of the ring plate.

[0007] Preferably, there are two suction cups, which are respectively located on the left and right sides of the base. An adjustment mechanism is provided, where a first electric push rod drives an abutment rod to slide along the inclined plane of the inclined block. Utilizing the inclined plane principle, the horizontal thrust is converted into a vertical lifting force. Combined with the guiding and limiting function of the telescopic rod, this allows for precise height adjustment of the platform and the dismantling equipment on it. Operators can adjust the dismantling equipment to the optimal working position with a single click according to different door lock installation heights, eliminating the need to hold heavy equipment throughout the process, significantly reducing labor intensity, extending continuous working time, and effectively improving dismantling efficiency. Simultaneously, a second electric push rod drives a ring plate to move the suction cups downwards and attach them to the ground, ensuring the base remains stable during equipment operation and preventing displacement due to equipment vibration or reaction forces, thus guaranteeing the accuracy and safety of the dismantling operation.

[0008] Move the base directly in front of the lock to be removed. Activate the second electric push rod. The piston rod of the second electric push rod extends, pushing the ring plate and suction cup downwards synchronously until the suction cup firmly adheres to the ground, stabilizing the base. Two suction cups are placed on the left and right sides of the base to ensure balanced force and prevent tipping. Activate the first electric push rod. The piston rod of the first electric push rod extends, pushing the contact rod horizontally to the right. The end of the contact rod contacts the inclined surface of the wedge block. Under the guidance of the inclined surface, the horizontal thrust is converted into a vertical upward force, pushing the wedge block upwards. The wedge block is fixedly connected to the bottom of the platform, so the platform rises synchronously with the wedge block. The telescopic rod extends and acts as a guide and limiter, ensuring the platform rises vertically without deviation. When the platform rises to the point where the working end of the removal equipment is aligned with the lock cylinder or panel, the first electric push rod stops, completing the height adjustment.

[0009] Preferably, the top of the platform is provided with a pulling mechanism, which includes a vertical plate fixedly connected to the top of the base. A third electric push rod is fixedly connected to the side of the vertical plate and is slidably connected to the demolition equipment.

[0010] Preferably, the top of the platform is provided with a first slide groove, a slider is slidably connected inside the first slide groove, and a connecting plate is fixedly connected to the top of the slider.

[0011] Preferably, the connecting plate has a second sliding groove inside, a movable block is slidably connected inside the second sliding groove, a movable plate is fixedly connected to the top of the movable block, the movable plate is set at the bottom of the dismantling equipment, and a spring is fixedly connected between the second sliding groove and the movable block.

[0012] Preferably, a contact plate is fixedly connected to the front of the movable plate, and a wave plate is fixedly connected to the top of the platform. The contact plate contacts the wave plate. By setting a pulling mechanism, the third electric push rod drives the dismantling device to reciprocate horizontally, realizing the automatic pulling and dismantling of the door lock panel and lock cylinder without manual force. At the same time, during the horizontal movement of the dismantling device, the connecting plate and the movable plate move synchronously. The contact plate at the front end of the movable plate periodically contacts the wave plate. Under the elastic force of the spring, the movable plate generates high-frequency micro-amplitude vibration along the second slide groove. This vibration is transmitted to the dismantling device, effectively assisting in the loosening and disengagement of the lock cylinder from the door body, reducing jamming, and improving the smoothness of dismantling. The cooperation between the first slide groove and the slider ensures that the movement trajectory is straight and stable during the pulling process, avoiding deviation and damage to the door structure.

[0013] Start the dismantling equipment, positioning its working end against the door lock panel, and simultaneously activate the third electric push rod. The piston rod of the third electric push rod extends, pushing the dismantling equipment horizontally away from the door, applying an outward pulling force to the lock cylinder. During horizontal movement, the bottom of the dismantling equipment remains in contact with the moving plate, pushing the moving plate to move synchronously. The moving plate is slidably connected to the second slide groove via a moving block, and a connecting plate is fixedly connected to its bottom. This connecting plate is slidably connected to the first slide groove via a slider, ensuring the moving plate moves along a straight trajectory. Simultaneously, the abutment plate fixed to the front of the moving plate moves with the moving plate, periodically contacting the wave plate fixed to the top of the platform. When the abutment plate passes the crest of the wave plate, it is pushed away from the surface, causing the moving plate and moving block to compress the spring backward along the second slide groove; when the abutment plate passes the trough of the wave plate, the spring releases its elasticity, pushing the moving block and moving plate forward along the second slide groove to reset. Under the reciprocating extension and retraction of the spring, the moving plate generates high-frequency micro-amplitude vibration, which is transmitted to the dismantling device above it, assisting in loosening the jam between the lock cylinder and the door.

[0014] Preferably, a cleaning mechanism is provided on the top of the platform. The cleaning mechanism includes a support plate fixedly connected to the top of the platform. A motor is fixedly connected to the side of the support plate, and a threaded rod is fixedly connected to the output end of the motor via a coupling. A threaded sleeve is threadedly connected to the outer wall of the threaded rod, and a fan is fixedly connected to the top of the threaded sleeve. A limit plate is fixedly connected to the side of the support plate, and the threaded sleeve contacts the limit plate. By setting up the cleaning mechanism, the motor drives the threaded rod to rotate, causing the threaded sleeve and fan to move horizontally back and forth along the direction of the limit plate. During the movement, the fan continuously blows air onto the demolition work area, promptly removing metal debris, wood chips, and dust generated during demolition, preventing debris from accumulating and obstructing vision or entering the equipment and causing jamming and wear. Simultaneously, compared to a fixed fan, the mobile fan has a wider coverage area and more thorough cleaning, effectively improving the working field of vision, reducing subsequent manual cleaning procedures, and further improving the overall efficiency of the demolition operation.

[0015] The cleaning mechanism is activated simultaneously during dismantling. The motor starts, and its output drives the threaded rod to rotate via a coupling. The threaded rod, in conjunction with the motor's forward and reverse rotation, drives the threaded sleeve to reciprocate along the threaded rod's axial direction. A fan is fixedly connected to the top of the threaded sleeve, and the fan reciprocates synchronously with the threaded sleeve. A limit plate is fixedly connected to the side of the support plate, contacting the threaded sleeve and restricting its rotation with the threaded rod, ensuring that the threaded sleeve only reciprocates in a straight line. During the reciprocating movement, the fan continuously blows air onto the dismantling area, blowing away metal debris, wood chips, and dust generated during dismantling, ensuring a clear field of vision and smooth equipment operation. After dismantling is completed, the motor, the third electric push rod, and the dismantling equipment are turned off in sequence. The second electric push rod is then activated to lift the suction cup off the ground, remove the base, and complete the entire dismantling operation.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This rapid door lock removal tool features an adjustment mechanism. A first electric push rod drives an abutment rod to slide along the inclined plane of a ramp, converting horizontal thrust into vertical lifting force using the ramp's engagement principle. Combined with the guiding and limiting function of a telescopic rod, this allows for precise height adjustment of the platform and the removal equipment. Operators can adjust the removal equipment to the optimal working position with a single click, eliminating the need to handle heavy equipment throughout the process, significantly reducing labor intensity, extending continuous working time, and effectively improving removal efficiency. Simultaneously, a second electric push rod drives a ring plate to move a suction cup downwards and adhere to the ground, ensuring the base remains stable during operation and preventing displacement due to equipment vibration or reaction forces, thus guaranteeing the accuracy and safety of the removal operation.

[0017] 2. This quick door lock removal tool, through the installation of a pulling mechanism, uses a third electric push rod to drive the removal device to reciprocate horizontally, achieving automatic pulling and removal of the door lock panel and lock cylinder without manual force. Simultaneously, during the horizontal movement, the removal device drives the connecting plate and the moving plate to move synchronously. The contact plate at the front end of the moving plate periodically contacts the wave plate, and under the elastic force of the spring, the moving plate generates high-frequency micro-amplitude vibrations along the second sliding groove. This vibration is transmitted to the removal device, effectively assisting in the loosening and disengagement of the lock cylinder from the door body, reducing jamming and improving the smoothness of removal. The cooperation between the first sliding groove and the slider ensures a straight and stable movement trajectory during the pulling process, preventing deviation and damage to the door structure.

[0018] 3. This quick door lock removal tool features a cleaning mechanism. A motor drives a threaded rod to rotate, causing a threaded sleeve and fan to move horizontally back and forth along the direction of the limiting plate. During this movement, the fan continuously blows air onto the removal area, promptly removing metal debris, wood chips, and dust generated during the removal process. This prevents debris from accumulating and obstructing vision or entering the equipment and causing jamming and wear. Furthermore, compared to a fixed blower, the mobile blower provides a wider coverage area and more thorough cleaning, effectively improving visibility, reducing subsequent manual cleaning steps, and further enhancing the overall efficiency of the removal operation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7One embodiment of the present invention is: a quick door lock removal tool, including a base 1, and a platform 2 is provided on the top of the base 1; An adjustment mechanism 3 is provided between the base 1 and the platform 2. The adjustment mechanism 3 includes a first fixing plate 311, which is fixedly connected to the top of the base 1. A first electric push rod 312 is fixedly connected to the side of the first fixing plate 311. An abutment rod 313 is fixedly connected to the side of the first electric push rod 312. An inclined block 314 is fixedly connected to the bottom of the platform 2. The abutment rod 313 contacts the inclined block 314. A telescopic rod 315 is fixedly connected between the base 1 and the platform 2. A removal device 4 is provided on the top of the platform 2. A second fixing plate 316 is fixedly connected to the side of the base 1. A second electric push rod 317 is fixedly connected to the bottom of the second fixing plate 316. A ring plate 318 is fixedly connected to the bottom of the second electric push rod 317. A suction cup 319 is fixedly connected to the bottom of the ring plate 318. There are two suction cups 319, which are respectively located on the left and right sides of the base 1.

[0023] Working principle: Move base 1 to the front of the door lock to be removed, activate the second electric push rod 317. The piston rod of the second electric push rod 317 extends, pushing the ring plate 318 and suction cup 319 downwards synchronously until the suction cup 319 firmly adheres to the ground, keeping base 1 stable. There are two suction cups 319, one on the left and one on the right side of base 1, ensuring that base 1 is evenly stressed and does not tip over. Activate the first electric push rod 312. The piston rod of the first electric push rod 312 extends, pushing the contact rod 313 horizontally to the right. The end of the contact rod 313 contacts the inclined surface of the inclined block 314. Under the guidance of the inclined surface, the horizontal thrust is converted into a vertical upward component, pushing the inclined block 314 upwards. The inclined block 314 is fixedly connected to the bottom of platform 2, so platform 2 rises synchronously with the inclined block 314. The telescopic rod 315 extends and acts as a guide and limiter, ensuring that platform 2 rises and falls vertically without deviation. When platform 2 rises to the working end of dismantling equipment 4 and aligns with the door lock cylinder or panel, the first electric push rod 312 stops moving, completing the height adjustment.

[0024] Please see Figure 1-7Based on the above embodiments, in another embodiment of the present invention, a pulling mechanism 5 is provided on the top of the platform 2. The pulling mechanism 5 includes a vertical plate 511, which is fixedly connected to the top of the base 1. A third electric push rod 512 is fixedly connected to the side of the vertical plate 511. The third electric push rod 512 is slidably connected to the demolition device 4. A first sliding groove 513 is provided on the top of the platform 2. A slider 514 is slidably connected inside the first sliding groove 513. A connecting plate 515 is fixedly connected to the top of the slider 514. A second sliding groove 517 is provided inside the connecting plate 515. A moving block is slidably connected inside the second sliding groove 517. A moving plate 516 is fixedly connected to the top of the moving block. The moving plate 516 is located at the bottom of the demolition device 4. A spring 518 is fixedly connected between the second sliding groove 517 and the moving block. An abutment plate 519 is fixedly connected to the front of the moving plate 516. A wave plate 520 is fixedly connected to the top of the platform 2. The abutment plate 519 contacts the wave plate 520.

[0025] Working principle: The dismantling device 4 is activated, its working end acting on the door lock panel, simultaneously activating the third electric push rod 512. The piston rod of the third electric push rod 512 extends, pushing the dismantling device 4 horizontally away from the door, applying an outward pulling force to the lock cylinder. During horizontal movement, the bottom of the dismantling device 4 remains in contact with the moving plate 516, pushing the moving plate 516 to move synchronously. The moving plate 516 is slidably connected to the second slide groove 517 via a moving block, and a connecting plate 515 is fixedly connected to its bottom. The connecting plate 515 is slidably connected to the first slide groove 513 via a slider 514, ensuring that the moving plate 516 moves along a straight trajectory. Simultaneously, the abutment plate 519 fixedly connected to the front of the moving plate 516 moves with the moving plate 516, periodically contacting the wave plate 520 fixed to the top of the platform 2. When the abutment plate 519 passes the crest of the wave plate 520, it is pushed away from the surface of the wave plate 520, causing the moving plate 516 and the moving block to compress the spring 518 backward along the second slide groove 517. When the abutment plate 519 passes the trough of the wave plate 520, the spring 518 releases its elastic force, pushing the moving block and the moving plate 516 forward along the second slide groove 517 to reset. Under the reciprocating extension and retraction of the spring 518, the moving plate 516 generates high-frequency micro-amplitude vibration, which is transmitted to the removal device 4 contacting it above, assisting in loosening the jam between the lock cylinder and the door body.

[0026] Please see Figure 1-7Based on the above embodiments, in another embodiment of the present invention, a cleaning mechanism 6 is provided on the top of the platform 2. The cleaning mechanism 6 includes a support plate 611, which is fixedly connected to the top of the platform 2. A motor 612 is fixedly connected to the side of the support plate 611. A threaded rod 613 is fixedly connected to the output end of the motor 612 through a coupling. A threaded sleeve 614 is threadedly connected to the outer wall of the threaded rod 613. A fan 615 is fixedly connected to the top of the threaded sleeve 614. A limiting plate 616 is fixedly connected to the side of the support plate 611. The threaded sleeve 614 contacts the limiting plate 616.

[0027] Working Principle: During the dismantling process, the cleaning mechanism 6 is activated simultaneously. Motor 612 starts, and its output drives the threaded rod 613 to rotate via a coupling. The threaded rod 613, in conjunction with the motor 612, rotates in both directions, driving the threaded sleeve 614 to reciprocate along the axial direction of the threaded rod 613. A fan 615 is fixedly connected to the top of the threaded sleeve 614, and the fan 615 reciprocates synchronously with the threaded sleeve 614. A limiting plate 616 is fixedly connected to the side of the support plate 611, contacting the threaded sleeve 614 and restricting its rotation with the threaded rod 613, ensuring that the threaded sleeve 614 only reciprocates in a straight line. During its reciprocating movement, the fan 615 continuously blows air onto the dismantling area, blowing away metal debris, wood chips, and dust generated during the dismantling process, ensuring a clear field of vision and smooth equipment operation. After dismantling is completed, motor 612, the third electric push rod 512, and the dismantling equipment 4 are sequentially turned off. The second electric push rod 317 is then activated to lift the suction cup 319 off the ground, removing the base 1 and completing the entire dismantling operation.
