Description

Technical Field

[0001] This invention relates to the field of mechanical alarm equipment technology, and in particular to a tilt alarm device. Background Technology

[0002] In daily life and industrial production, long door handles are widely used in doors, windows, safes, equipment cabinets and other scenarios. In some scenarios (such as valuables storage cabinets, security doors and windows, special equipment cabinets), it is necessary to monitor the tilt status of the door handle. When the door handle is abnormally pried or tilted, an alarm signal should be issued in time to remind staff or users to pay attention to safety.

[0003] Currently, existing door handle tilt alarm devices cannot be quickly installed or disassembled and are difficult to adapt to long door handles of different sizes. Most existing devices use rigid fasteners such as bolts and screws to fix them to the door handle or mounting surface. Installation requires special tools such as screwdrivers and wrenches, which is cumbersome and time-consuming. Disassembly also requires tools, which is not conducive to the quick inspection, replacement or reuse of the device. At the same time, their installation structure is mostly designed with fixed size and lacks adjustability. It cannot flexibly adapt to long door handles of different diameters and specifications, resulting in one device being able to only correspond to one size of door handle. This has extremely poor versatility and cannot meet the needs of long door handles in various scenarios such as doors, windows and cabinets, thus limiting the promotion and application of the device. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a tilt alarm device that can be quickly installed and removed from long door handles of different specifications.

[0005] The objective of this invention is achieved through the following technical solution:

[0013] The drive mechanism is located within the receiving space and is used to drive the winding device to release the fixing strap that extends into the receiving space;

[0014] The restraint mechanism is located within the receiving space and is used to restrain the winding device from releasing the fixing strap that extends into the receiving space;

[0015] The release mechanism is located within the accommodating space and is used to release the constraint mechanism from the driving mechanism.

[0016] Furthermore, the housing is provided with a strap groove, one end of the fixing strap is detachably connected to the outer shell of the housing, and the other end is movably inserted into the strap groove.

[0017] Furthermore, the fixing strap is an anti-slip strap.

[0018] Furthermore, the fixing straps are provided in multiple pieces, and the multiple fixing straps together enclose the installation space.

[0019] Furthermore, the tilt detection module is made using a triaxial accelerometer.

[0020] Furthermore, the control module is made using an ESP32-C3.

[0021] Furthermore, the tilt alarm device also includes a power supply module, which is located in the housing and is used to supply power to the tilt detection module, the alarm module, and the control module.

[0022] Furthermore, the drive mechanism includes a mounting shaft, a first gear, and a torsion spring; the winding device is driven by a second gear; the mounting shaft is located within the receiving space; the first gear is rotatably sleeved on the mounting shaft; the first gear and the second gear mesh with each other; the torsion spring is sleeved on the mounting shaft; the two ends of the torsion spring are respectively connected to the first gear and the inner wall of the receiving space; the torsion spring is used to drive the first gear to drive the second gear, thereby causing the winding device to release the fixing strap extending into the receiving space.

[0023] Further, the constraint mechanism includes a mounting bracket, a biting block, a constraint block, and a first reset member. The mounting bracket is disposed within the accommodating space and has a guide rail. The biting block is slidably mounted on the guide rail and can mesh with the first gear. The direction in which the biting block points to the constraint block is defined as a first direction. The constraint block is disposed on the guide rail and located on one side of the biting block in the direction of the guide rail. The constraint block is used to prevent the biting block from sliding along the first direction. The first reset member is connected to the biting block and the mounting bracket at both ends, and the first reset member drives the biting block to mesh with the first gear.

[0024] Furthermore, the constraint block has a pushed portion, and the release mechanism includes a push rod and a second reset member. The push rod is movably inserted through the housing and has a pressing end and a pushing end. The pressing end is for the user to press and is located outside the receiving space. The pushing end is used to push the pushed portion of the constraint block to drive the constraint block to prevent the engaging block from sliding in the first direction. The two ends of the second reset member are respectively connected to the push rod and the inner wall of the receiving space, and have a tendency to drive the pushing end of the push rod to push the pushed portion.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. A fixing strap, one end of which is movably connected to the outer shell of the housing, and the other end which is movably inserted through the housing and extends into the receiving space to form an installation space for accommodating a door handle; a winding device is rotatably fitted onto the housing, the winding device having a winding end and a driving end, the winding end being used to wind up or release the fixing strap extending into the receiving space, and the driving end being used by the user to quickly drive the winding end to wind up the fixing strap extending into the receiving space. This invention allows for rapid winding of the fixing strap by driving the driving end of the winding device, and adjustment of the installation space size by releasing the fixing strap through the winding end, adapting to long door handles of different specifications. It eliminates the need for separate devices for different door handle specifications, and simultaneously achieves rapid fixing of the device to the door handle, significantly improving the adaptability and ease of installation of the device.

[0027] 2. The invention comprises a drive mechanism located within the receiving space, used to drive the winding device to release the fixing strap extending into the receiving space; a constraint mechanism located within the receiving space, used to constrain the winding device from releasing the fixing strap extending into the receiving space; and a release mechanism located within the receiving space, used to release the constraint mechanism from the drive mechanism. This configuration allows for rapid release of the constraint via the release mechanism, and automatic release of the fixing strap by the drive mechanism, enabling rapid disassembly of the device. After disassembly, the constraint mechanism can re-constrain the drive mechanism, ensuring the stability of the device after installation and preventing loosening or detachment during use. This achieves both rapid assembly and disassembly and ensures the reliability of the device.

[0028] 3. Based on the integrated design of the housing, tilt detection module, alarm module, control module, fixing straps, and winding device, the invention integrates various components related to disassembly and assembly, including the housing, tilt detection module, alarm module, control module, fixing straps, and winding device. The housing contains a space to accommodate the extensions of each functional module and the fixing straps. This design integrates the tilt alarm function with the quick disassembly and assembly function, eliminating the need for additional disassembly and assembly auxiliary structures. It achieves quick disassembly and assembly of door handles of different sizes and tilt alarm functionality through the linkage of existing components. The overall structure is compact and reasonable, reducing the manufacturing cost and size of the device, facilitating user portability and operation, and further enhancing the device's practicality. Simultaneously, it realizes the dual functions of "quick disassembly and assembly" and "tilt alarm," improving the overall value of the device. Attached Figure Description

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] See Figures 1-4 A preferred embodiment of the present invention provides a tilt alarm device, comprising: a housing 1, a tilt detection module 2, an alarm module 3, a control module, a fixing strap 4, a winding device 5, a driving mechanism 6, a restraint mechanism 7, and a release mechanism 8.

[0038] The housing 1 is provided with a receiving space 101;

[0039] The tilt detection module 2 is disposed within the accommodating space 101, and the tilt detection module 2 is used to detect the change in the tilt angle of the housing 1;

[0040] The alarm module 3 is mounted on the housing 1;

[0041] The control module is electrically connected to the tilt detection module 2 and the alarm module 3 respectively;

[0042] One end of the fixing strap 4 is movably connected to the outer shell of the housing 1, and the other end is movably inserted through the housing 1 and extends into the receiving space 101 to form an installation space for accommodating the door handle.

[0043] The winding device 5 is rotatably sleeved on the housing 1. The winding device 5 has a winding end 501 and a driving end 502. The winding end 501 is used to wind up or release the fixing strap 4 extending into the receiving space 101. The driving end 502 is used for the user to quickly drive the winding end 501 to wind up the fixing strap 4 extending into the receiving space 101.

[0044] The drive mechanism 6 is disposed within the receiving space 101 and is used to drive the winding device 5 to release the fixing strap 4 extending into the receiving space 101;

[0045] The restraint mechanism 7 is disposed within the receiving space 101 and is used to restrain the winding device 5 from releasing the fixing strap 4 that extends into the receiving space 101;

[0046] The release mechanism 8 is located within the accommodating space 101 and is used to release the constraint mechanism 7 from the drive mechanism 6.

[0047] The working principle of this invention is as follows: During operation, the user operates the release mechanism 8 to release the constraint mechanism 7 from the drive mechanism 6. The drive mechanism 6 then drives the winding device 5 to release the fixing strap 4, creating an installation space for the door handle to accommodate long door handles of different specifications. After placing the door handle in the installation space, the user quickly winds the fixing strap 4 until it fits tightly against the door handle using the drive end 502 of the winding device 5, completing the fixation. The constraint mechanism 7 resets the constraint on the drive mechanism 6 to prevent loosening. The internal accommodating space 101 of the housing 1 provides installation space for each module and also serves a protective function. The tilt detection module 2 continuously detects changes in the tilt angle of the housing 1. Since the housing 1 is fixed to the door handle, its tilt change corresponds to the target tilt state, enabling real-time monitoring. The control module receives and analyzes the signal from the tilt detection module 2. When the tilt angle exceeds a preset threshold, the control module triggers the alarm module 3 to issue a warning, thus triggering a tilt alarm. When disassembling or replacing the door handle, the user operates the release mechanism 8 again to release the constraint, and the drive mechanism 6 drives the winding device 5 to release the fixing strap 4, allowing for quick removal of the device. The components work together to achieve real-time detection and alarm of target tilt, and also enable quick installation and removal of the device on door handles of different sizes. It is highly adaptable, easy to operate, and ensures flexibility and practicality in use.

[0048] Among them, alarm module 3 can be a buzzer, a warning light, or a combination of both.

[0049] Obviously, one end of the fixing strap 4 is movably connected to the outer shell of the housing 1, and the other end is movably inserted through the housing 1 into the receiving space 101, forming an installation space for accommodating the door handle. The winding device 5 is rotatably sleeved on the housing 1. The winding device 5 has a winding end 501 and a driving end 502. The winding end 501 is used to wind up or release the fixing strap 4 extending into the receiving space 101, and the driving end 502 is used for quick driving by the user to drive the winding end 501 to wind up the fixing strap 4 extending into the receiving space 101. This invention allows for the rapid winding of the fixing strap 4 by driving the driving end 502 of the winding device 5, and the adjustment of the installation space size by releasing the fixing strap 4 by the winding end 501. It adapts to long door handles of different specifications, eliminating the need for separate devices for different door handle specifications, and simultaneously achieving rapid fixation of the device to the door handle, greatly improving the adaptability and ease of installation of the device.

[0050] The drive mechanism 6 is located within the receiving space 101 and is used to drive the winding device 5 to release the fixing strap 4 extending into the receiving space 101; the constraint mechanism 7 is located within the receiving space 101 and is used to constrain the winding device 5 from releasing the fixing strap 4 extending into the receiving space 101; the release mechanism 8 is located within the receiving space 101 and is used to release the constraint mechanism 7 from the drive mechanism 6. This design allows for rapid release of the constraint by operating the release mechanism 8, and automatic release of the fixing strap 4 by the drive mechanism 6, enabling rapid disassembly of the device. After disassembly, the constraint mechanism 7 can re-constrain the drive mechanism 6, ensuring the stability of the device after installation and preventing loosening or detachment during use. This achieves both rapid assembly and disassembly and ensures the reliability of the device.

[0051] Based on the integrated design of the housing 1, tilt detection module 2, alarm module 3, control module, fixing strap 4, and winding device 5, the housing 1 has an internal accommodating space 101 to accommodate the various functional modules and the extension of the fixing strap 4. This design integrates the tilt alarm function with the quick disassembly / reassembly function, eliminating the need for additional disassembly / reassembly auxiliary structures. It achieves quick disassembly / reassembly and tilt alarm functions for door handles of different sizes by relying on the linkage of existing components. The overall structure is compact and reasonable, reducing the manufacturing cost and size of the device, facilitating user portability and operation, and further enhancing the device's practicality. Simultaneously, it achieves the dual functions of quick disassembly / reassembly and tilt alarm, improving the overall value of the device.

[0052] refer to Figure 1 , Figure 2 and Figure 3Preferably, the housing 1 is provided with a strapping groove 102, one end of the fixing strap 4 is detachably connected to the outer shell of the housing 1, and the other end is movably inserted into the strapping groove 102. This arrangement allows the strapping groove 102 to limit and guide the movable end of the fixing strap 4, preventing deviation or entanglement during winding and unwinding, ensuring that the fixing strap 4 can move smoothly along the set trajectory, thereby achieving quick and stable fixing of the device to door handles of different specifications. The fixing strap 4 is detachably connected, and can be hinged to the outer shell of the housing 1 using a buckle or bolt, facilitating quick replacement if the strap is damaged. The strapping groove 102 is adaptable to the width of the strap, and the groove wall of the strapping groove 102 can be made of wear-resistant material.

[0053] Preferably, the fixing strap 4 is an anti-slip strap. This design increases the friction between the fixing strap 4 and the door handle surface through the anti-slip properties of the strap itself, preventing slippage or loosening due to door vibration or external force after the device is fixed. This ensures the stability of the connection between the device and the door handle, thereby guaranteeing that the tilt detection module 2 can accurately detect changes in the tilt angle of the housing 1 and the door handle, avoiding detection deviations and delayed alarms caused by loosening. Simultaneously, the anti-slip properties reduce slippage when the fixing strap 4 is wound up, allowing the user to quickly tighten the strap to fit the door handle using the drive end 502 of the winding device 5. This further improves the installation efficiency and fixing reliability of the device, adapts to the disassembly and assembly needs of long door handles of different specifications, and extends the service life of the strap. The anti-slip strap can be made of rubber or webbing material with anti-slip textures on the surface, further enhancing the anti-slip effect and fit.

[0054] refer to Figure 1 and Figure 2 Preferably, the fixing straps 4 are provided in multiple pieces, which together enclose the installation space. This arrangement, with multiple fixing straps 4 forming the installation space, makes the contact points between the fixing straps 4 and the door handle more even, distributing the weight of the device itself and the forces generated during use, preventing excessive stress on a single strap that could lead to loosening or breakage, and significantly improving the stability and reliability of the connection between the device and the door handle. Simultaneously, the tension of each of the multiple straps can be independently adjusted via the winding device 5, better adapting to long door handles of different thicknesses and cross-sectional shapes, further expanding the device's adaptability range, ensuring a tight fit and fixation for door handles of various specifications. Combined with the winding device 5, drive mechanism 6, and other components, it further optimizes the quick assembly and disassembly effect, ensuring that the device will not shift after installation and ensuring the detection accuracy of the tilt detection module 2. The multiple fixing straps 4 can be evenly distributed around the perimeter of the housing 1, further improving the stability of the enclosure and fixation. The straps can be made of the same specification of anti-slip straps, balancing anti-slip properties and durability.

[0055] Preferably, the tilt detection module 2 is made of a triaxial accelerometer. This configuration utilizes the characteristics of the triaxial accelerometer to achieve comprehensive and accurate detection of tilt angle changes of the housing 1 in the X, Y, and Z directions. Compared to single-axis or dual-axis sensors, it effectively avoids detection blind spots, ensuring that tilting of the housing 1 (i.e., the door handle) can be detected promptly regardless of the direction of tilt, significantly improving the comprehensiveness and accuracy of tilt detection. In addition to the triaxial accelerometer, the tilt detection module 2 can also use a dual-axis tilt sensor or a mercury tilt switch. Furthermore, when the triaxial accelerometer detects a change in the triaxial gravity vector exceeding a set threshold, it triggers the control module to enter the working state from sleep mode via an interrupt pin (INT).

[0056] Preferably, the control module is made of ESP32-C3. This configuration fully utilizes the core characteristics of the ESP32-C3 chip, such as high integration, low power consumption, and small size. Its compact size perfectly fits the space 101 within the housing 1, without requiring excessive additional installation space. It can be compactly arranged with components such as the tilt detection module 2 and the alarm module 3 without affecting the overall compactness of the device. The ESP32-C3 has stable signal processing capabilities and a fast response speed. It can receive the tilt angle signal transmitted by the tilt detection module 2 in real time, quickly complete signal analysis and judgment, and promptly send control commands to the alarm module 3, ensuring the timeliness and reliability of the alarm function and avoiding the problem of delayed alarms due to signal processing lag. In addition to ESP32-C3, the control module can also use low-power controllers such as HK32L084 or STM32L0.

[0057] refer to Figure 1 and Figure 2 Preferably, the tilt alarm device further includes a power supply module 9, which is located in the housing 1 and supplies power to the tilt detection module 2, the alarm module 3, and the control module. This configuration ensures that the power supply module 9 provides stable and continuous power to the core functional modules of the device, guaranteeing that the tilt detection module 2 can continuously and accurately detect changes in the tilt angle of the housing 1 and the door handle, the control module can process the detection signals in real time and trigger alarm commands, and the alarm module 3 can promptly issue alarm prompts. This ensures the stable and coordinated operation of all components of the device and avoids problems such as the device malfunctioning or alarm failure due to unstable power supply or power outages. The power supply module 9 can be a combination of a lithium battery and a battery holder or a button battery and a battery holder. Furthermore, the power supply module 9 can be located in the housing space 101 outside or inside the housing 1, depending on the actual situation.

[0058] refer to Figure 4Preferably, the drive mechanism 6 includes a mounting shaft 601, a first gear 602, and a torsion spring 603; the winding device 5 is driven by a second gear 10; the mounting shaft 601 is disposed within the accommodating space 101; the first gear 602 is rotatably sleeved on the mounting shaft 601; the first gear 602 and the second gear 10 mesh with each other; the torsion spring 603 is sleeved on the mounting shaft 601; the two ends of the torsion spring 603 are respectively connected to the first gear 602 and the inner wall of the accommodating space 101; the torsion spring 603 is used to drive the first gear 602 to drive the second gear 10, thereby causing the winding device 5 to release the fixing strap 4 extending into the accommodating space 101. This configuration utilizes the elastic reset characteristic of the torsion spring 603 to provide a stable and continuous driving force for the winding device 5 to release the fixing strap 4, eliminating the need for additional power components such as motors. This simplifies the structure of the drive mechanism 6, reduces the overall size, and perfectly fits the internal space 101 of the housing 1 without interfering with the layout of other components. The first gear 602 meshes with the second gear 10, ensuring precise and smooth transmission. This allows the elastic force of the torsion spring 603 to be smoothly transmitted to the winding device 5, ensuring the fixing strap 4 is released at a uniform speed and smoothly, avoiding jamming or tangling during release, and improving the ease of installation. The torsion spring 603 has a simple structure, is durable, and inexpensive, requiring no complex maintenance. Combined with the limiting and guiding function of the mounting shaft 601 on the first gear 602, it ensures the long-term stable operation of the drive mechanism 6. When the release mechanism 8 is released, the torsion spring 603 can quickly drive the gear transmission, enabling the fastening of the fixing strap 4, further optimizing the efficiency of device assembly and disassembly. At the same time, the elastic force of the torsion spring 603 can flexibly adapt to the strap release length required for different sizes of door handles, improving the adaptability of the device. Among them, the first gear 602 and the second gear 10 can be made of wear-resistant gear material to reduce transmission wear and extend service life. The mounting shaft 601 can be fixedly connected to the housing 1 to further improve the installation stability of the drive mechanism 6.

[0059] refer to Figure 4Preferably, the constraint mechanism 7 includes a mounting frame 701, a biting block 702, a constraint block 703, and a first reset member 704. The mounting frame 701 is disposed within the accommodating space 101 and has a guide rail 7011. The biting block 702 is slidably mounted on the guide rail 7011 and can mesh with the first gear 602. The direction in which the biting block 702 points to the constraint block 703 is defined as a first direction. The constraint block 703 is disposed on the guide rail 7011 and located on one side of the biting block 702 in the direction of the guide rail 7011. The constraint block 703 is used to prevent the biting block 702 from sliding along the first direction. The first reset member 704 is connected to the biting block 702 and the mounting frame 701 at both ends, and the first reset member 704 drives the biting block 702 to mesh with the first gear 602. This configuration allows the first reset element 704 to continuously drive the biting block 702 to slide along the guide rail 7011 and tightly engage with the first gear 602 of the drive mechanism 6, thereby firmly constraining the rotation of the first gear 602. This, in turn, restricts the winding device 5 from releasing the fixing strap 4, ensuring that the strap will not loosen due to the driving force of the torsion spring 603 or external vibration after the device is installed and fixed. This ensures the stability of the connection between the device and the door handle. The guide rail 7011 on the mounting bracket 701 provides precise sliding guidance for the biting block 702, preventing the biting block 702 from deviating or getting stuck during sliding. This ensures that the biting block 702 can accurately engage with the first gear 602, improving the reliability of the constraint. The constraint block 703 can effectively limit the excessive sliding of the biting block 702 along the first direction, preventing the biting block 702 from misaligning with the first gear 602, further ensuring the constraint effect. The first reset component 704 can be a spring, which provides stable elastic reset and is inexpensive. The meshing surfaces of the biting block 702 and the first gear 602 can be provided with anti-slip teeth to further improve meshing stability and prevent slippage that could lead to constraint failure.

[0060] refer to Figure 4Preferably, the constraint block 703 has a pushed portion 7031, and the release mechanism 8 includes a push rod 801 and a second reset member 802. The push rod 801 is movably inserted through the housing 1. The push rod 801 has a pressing end 8011 and a pushing end 8012. The pressing end 8011 is for the user to press and is located outside the receiving space 101. The pushing end 8012 is used to push the pushed portion 7031 of the constraint block 703 to drive the constraint block 703 to prevent the engaging block 702 from sliding in the first direction. The two ends of the second reset member 802 are respectively connected to the push rod 801 and the inner wall of the receiving space 101, and have a tendency to drive the pushing end 8012 in the push rod 801 to push the pushed portion 7031. This configuration allows the push rod 801 to remain in a pushing state continuously through the elastic driving force of the second reset member 802, ensuring that the constraint block 703 always has the ability to prevent the engagement block 702 from engaging, thereby stably maintaining the constraint effect on the first gear 602. This ensures that the straps will not loosen due to accidental contact or vibration during installation, greatly improving the reliability and safety of the device's fixation. The pressing end 8011 of the push rod 801 is located outside the housing 1, allowing the user to operate it directly without disassembling the housing 1. Pressing the pressing end 8011 drives the push rod 801 to move in the opposite direction. The constraint block 703 quickly releases its obstruction of the engagement block 702, instantly unlocking the drive mechanism 6. Combined with the power of the torsion spring 603 of the drive mechanism 6, the fixing strap 4 can be automatically released with a single click, significantly improving the convenience and efficiency of device disassembly. The entire release mechanism 8 achieves the switching between constraint and release using a purely mechanical structure, without relying on electronic control. Its simple and compact structure, rapid response, and perfect fit within the narrow space 101 of the housing 1 do not interfere with the normal operation of other core components. Furthermore, the mechanical self-locking principle further ensures stability and durability during use. The second reset component 802 can be a tension spring; the pushed part 7031 and the pushing end 8012 can be engaged by a sloping sliding fit.

[0061] In another preferred embodiment, the alarm module 3, the control module, the tilt detection module 2, and the power supply module 9 are all integrated into the housing space 101 within the housing 1 to form an integrated structure, thereby achieving tight fixation of the entire device and the door handle.
