Description

Technical Field

[0001] This utility model relates to the field of tilt switch installation technology, specifically a stable tilt switch assembly. Background Technology

[0002] A tilt switch, also known as a tilting switch or fall switch, is a safety control component designed based on the principle of gravity sensing. Its core function is to automatically trigger the switching of the circuit's on / off state when the equipment or carrier tilts, falls, or flips at a specific angle, thereby achieving protection, alarm, or shutdown control of the associated equipment. It is widely used in various electrical equipment that require anti-tipping safety protection.

[0003] Current tilt switch installation methods have many drawbacks. Regarding the fixing structure, most methods rely on a single fixing method, such as the common screw fixing. This method only constrains the tilt switch in one dimension. In complex working environments, such as strong vibrations or large temperature fluctuations causing material expansion and contraction, the tilt switch is prone to shifting or loosening, leading to decreased detection accuracy or even complete loss of protection function, greatly increasing the safety risks of equipment operation. Furthermore, simple screw fixing cannot simultaneously ensure the tilt switch's positional stability in both the lateral and longitudinal directions, failing to meet the stringent requirements for installation stability. In demanding application scenarios, from the perspective of operational convenience, traditional transmission structures are complex in design. During installation, professional personnel often need to use various tools for precise adjustment, making the operation process cumbersome and consuming a lot of manpower and time. In mass production or equipment maintenance, frequent installation and disassembly work further amplifies this inconvenience. Taking a certain home appliance manufacturer as an example, when using the traditional tilt switch installation method, it took an average of about 15 minutes to install the tilt switch on each piece of equipment. If it involved later maintenance and replacement, due to the difficulty of disassembling and fixing the screws, a single maintenance time could be as long as 30 minutes or more, which seriously affected production and maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a stable tilt switch assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable tilt switch assembly, including a tilt switch, a stabilizing support plate at the bottom of the tilt switch, a cavity inside the stabilizing support plate, a rotating linkage rod rotating inside the cavity, a linkage component fixed to the outer wall of the rotating linkage rod, clamping components for clamping the tilt switch fixed to the top of both sides of the linkage component, a limiting slide rail fixed to one side of the top of the stabilizing support plate, a lifting pressure plate for pressing the tilt switch sliding on the outer wall of the limiting slide rail, and a limiting component for limiting the lifting pressure plate fixed to one side wall of the lifting pressure plate.

[0006] Preferably, the linkage component includes a drive turbine, the outer wall of the linkage rod is fixed with the drive turbine, one side of the drive turbine is engaged with a drive worm, and one side wall of the drive worm is fixed with a drive rod.

[0007] Preferably, the outer wall of the drive turbine is provided with an oblique groove, and the outer wall of the drive worm is provided with a protrusion that matches the outer wall of the drive turbine, so that the drive turbine can be driven to rotate through the thread transmission principle.

[0008] Preferably, the clamping member includes a driven gear, the driven gear is fixed to the bottom of the outer wall of the linkage rod, a sliding rack is meshed with the outer wall of the driven gear, a linkage vertical rod is fixed to the top of the sliding rack, and a sliding clamping plate is fixed to the inner side of the top of the linkage vertical rod.

[0009] Preferably, the inner wall of the sliding clamp is fixed with a rubber pad, which can increase the clamping force of the sliding clamp on the tilt switch.

[0010] Preferably, the limiting component includes a limiting crossbar, a limiting crossbar is fixed to one side wall of the lifting pressure plate, a sliding plate is slidably mounted on the outer wall of the limiting crossbar, and a limiting insert is fixed to the side of the sliding plate near the lifting pressure plate.

[0011] Preferably, the side wall of the limiting slide rail is provided with multiple limiting holes, which, together with the limiting rod, can limit the lifting pressure plate.

[0012] Preferably, the limiting crossbar is T-shaped, and a spring is fixed to one end face of the T-shaped crossbar. The spring is a return spring, and the other end of the return spring is fixed to one side wall of the sliding plate. The elasticity of the return spring can drive the sliding plate to return to its original position.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Multi-dimensional secure fixing enhances installation reliability:

[0015] The component achieves stable installation of the tilt switch through a dual fixing structure of "clamping + pressing": On the one hand, the transmission clamping mechanism, consisting of a drive rod, drive worm gear, drive turbine, linkage rod, driven gear, sliding rack, linkage vertical rod, and sliding clamping plate, can drive the sliding clamping plate to clamp the tilt switch inward synchronously through precise transmission of gears and worm gear. The rubber pad on the inner side of the sliding clamping plate can further enhance the clamping force and avoid clamping damage, ensuring the lateral stability of the tilt switch. On the other hand, the pressing and limiting mechanism, consisting of a limit slide rail, lifting pressure plate, and limiting components, can fix the top of the tilt switch by longitudinal pressing of the lifting pressure plate. At the same time, the cooperation of the limit rod and multiple sets of limit holes on the limit slide rail can achieve precise limiting of the lifting pressure plate at different heights. The dual fixing structure effectively avoids problems such as displacement and loosening of the tilt switch after installation, greatly improving the structural stability and reliability of use after installation.

[0016] 2. The transmission structure is precise and controllable, and the operation is convenient and efficient:

[0017] The component adopts a transmission design combining a worm gear and rack and pinion, with a clear transmission path and high transmission efficiency: the operator only needs to rotate the drive rod to drive the entire clamping mechanism, without the need for complicated tools or professional operating skills, simplifying the installation process; at the same time, the "T"-shaped limit bar in the limit component, combined with the design of the reset spring, allows the limit and unlocking operation of the lifting pressure plate to be completed in only three steps: "pull the sliding plate - adjust the pressure plate height - release and reset". The operation is simple and smooth, which greatly reduces the difficulty of installing and disassembling the tilt switch and improves the assembly efficiency, making it especially suitable for batch installation or later maintenance scenarios.

[0018] 3. The reset structure automatically locks, ensuring safe use:

[0019] The return spring design in the limit component has automatic reset and locking functions: after adjusting the height of the lifting pressure plate, releasing the slide plate will cause the slide plate to automatically reset through the elastic force of the return spring, so that the limit rod is accurately inserted into the limit hole of the limit slide rail, realizing the automatic locking of the lifting pressure plate. No manual additional fixing operation is required, which not only avoids the safety hazards caused by incomplete manual locking, but also prevents the limit rod from falling out due to vibration and other factors during use, further ensuring the stability and safety of the tilt switch after installation.
