Description

Technical Field

[0001] This utility model relates to the field of safety elevator technology, specifically a pressure alarm safety elevator. Background Technology

[0002] Ladders, as a core tool for working at heights, are widely used in home repairs, construction, and electrical maintenance, and their safety is directly related to the life safety of users. However, traditional ladder designs are based on "passive protection," relying on the strength of the mechanical structure and user experience, lacking active monitoring and intelligent early warning functions, and thus posing the following prominent safety hazards.

[0003] First, the accuracy of load-bearing monitoring is insufficient. Although existing improved ladders integrate pressure sensors, the sensor installation position may be unreasonable, failing to accurately sense the overall load-bearing capacity of the ladder, resulting in errors in the monitoring data. Second, the alarm effect is limited. Alarms are mostly single-sound alerts, which are easily ignored in noisy environments and cannot promptly remind users of the risk of overloading. Third, the unfolding stability needs improvement. The support rods on both sides are mostly connected by simple hinges, relying solely on friction to maintain balance after unfolding, lacking an effective spacing fixing mechanism. When the user moves on the ladder, the support rods are prone to retracting inward or swaying left and right, especially on soft ground, posing a high risk of collapse. In view of this, this utility model aims to solve the above problems and provide a pressure-alarm safety system that can accurately monitor load-bearing capacity, provide effective alarms, and unfold stably. Utility Model Content

[0004] The purpose of this invention is to provide a pressure alarm safety elevator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure alarm safety ladder, comprising a first rotating shaft, a support rod, and a first connecting plate, wherein support rods are installed on both sides of the first rotating shaft, a first connecting plate is provided on the inner side of the support rod, and a processing structure is installed at the bottom of the support rod;

[0006] The processing structure includes a second connecting plate, a pressure sensor, and a second protective pad. The second connecting plate is installed at the bottom of the support rod, the pressure sensor is installed on the inner side of the second connecting plate, the second protective pad is installed at the bottom of the second connecting plate, and an LED flashing light is installed on the lower part of the outer wall of the support rod.

[0007] Preferably, the pressure sensor is electrically connected to an LED flashing light, and the pressure sensor is powered by a battery.

[0008] Preferably, the second connecting plate and the second protective pad are fitted together tightly.

[0009] Preferably, the support rods on both sides are rotatably connected by a first rotating shaft, and the first rotating shaft is perpendicular to the support rods.

[0010] Preferably, a first anti-slip pad is installed on the outer side of each support rod.

[0011] Preferably, a rotating structure is provided between the two support rods, and the outer side of the rotating structure is fixedly connected to the outer wall of the first connecting plate.

[0012] Preferably, the rotating structure includes a second rotating shaft, a connecting rod, and a third rotating shaft. The second rotating shaft is installed on the outer wall of the support rod, and a connecting rod is installed on the outer side of the second rotating shaft. The two connecting rods are connected to each other through the third rotating shaft.

[0013] Preferably, the connecting rod and the second rotating shaft are rotatably connected.

[0014] Preferably, the connecting rods on both sides are rotatably connected via a third rotating shaft.

[0015] Preferably, the support rod, the first connecting plate, and the rotating structure are all made of high-strength aluminum alloy.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting a first rotating shaft, a support rod and a first connecting plate, support rods are installed on both sides of the first rotating shaft, a first connecting plate is provided on the inner side of the support rod, and a processing structure is installed at the bottom of the support rod;

[0018] The processing structure includes a second connecting plate, a pressure sensor, and a second protective pad. The second connecting plate is installed at the bottom of the support rod, the pressure sensor is installed on the inner side of the second connecting plate, the second protective pad is installed at the bottom of the second connecting plate, and an LED flashing light is installed on the lower part of the outer wall of the support rod, in a position that is easy for the user to observe.

[0019] The pressure sensor is electrically connected to the LED flashing light. The pressure sensor is powered by a battery and is embedded inside the second connecting plate at the point of contact with the ground.

[0020] The second connecting plate and the second protective pad are designed to fit tightly together, increasing friction with the ground and preventing the ladder from slipping.

[0021] The two support rods are rotatably connected by the first pivot, unfolding into an "A" shape. The first pivot is the core rotation hub of the ladder, connecting the two support rods to realize the folding and unfolding functions. The first pivot and the support rods are set perpendicular to each other.

[0022] The outer side of each support rod is equipped with a first anti-slip pad to prevent users from slipping.

[0023] A rotating structure is installed between the two support rods. The rotating structure restricts the swaying of the support rods, prevents over-expansion or inward tilting, and keeps the ladder stable. The outer side of the rotating structure is fixedly connected to the outer wall of the first connecting plate. The first connecting plate is a horizontal structure that the user steps on. It is fixed between the two support rods and is parallel to the support rods when folded.

[0024] The rotating structure includes a second rotating shaft, a connecting rod, and a third rotating shaft. The second rotating shaft is installed on the outer wall of the support rod, and the connecting rod is installed on the outer side of the second rotating shaft. The two connecting rods are connected to each other through the third rotating shaft.

[0025] The connecting rod and the second rotating shaft are rotatably connected.

[0026] The two connecting rods are rotatably connected by a third rotating shaft, which serves as the pivot for the rotation of the two connecting rods.

[0027] The support rod, the first connecting plate, and the rotating structure are all made of high-strength aluminum alloy, which is lightweight and has strong compressive strength.

[0028] Working principle:

[0029] When the two support rods are unfolded via the first pivot, the connecting rod of the rotating structure rotates synchronously around the second and third pivots. Once the support rods reach a safe angle, the third pivot locks the connecting rod, fixing the distance between the two support rods to prevent the inside from swaying or collapsing. When the support rods are rotated in the opposite direction, the connecting rods fold together and eventually become parallel to the support rods. After folding, the volume is reduced by 40%, making it easy to store and carry.

[0030] When a user steps on the first connecting plate, the weight is transferred to the second connecting plate at the bottom through the support rod. The pressure sensor is in close contact with the second connecting plate and directly senses the ground reaction force, converting the mechanical pressure into an electrical signal. The pressure sensor is electrically connected to the LED flashing light and is powered by a built-in battery, resulting in low power consumption. When the load exceeds the preset threshold, the electrical signal triggers the LED flashing light to flash at a high frequency, reminding the user of the overload risk and preventing the ladder from breaking or tipping over due to excessive force.

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

[0040] Example 1:

[0041] Please see Figure 1-4This utility model provides a pressure alarm safety ladder technical solution: a pressure alarm safety ladder includes a first rotating shaft 1, a support rod 2 and a first connecting plate 3. The support rod 2 is installed on both sides of the first rotating shaft 1, the first connecting plate 3 is provided on the inner side of the support rod 2, and a processing structure 4 is installed at the bottom of the support rod 2.

[0042] The processing structure 4 includes a second connecting plate 401, a pressure sensor 402, and a second protective pad 403. The second connecting plate 401 is installed at the bottom of the support rod 2. The pressure sensor 402 is installed on the inner side of the second connecting plate 401. The second protective pad 403 is installed at the bottom of the second connecting plate 401. An LED flashing light 404 is installed on the lower part of the outer wall of the support rod 2, which is an easy position for the user to observe.

[0043] The pressure sensor 402 is electrically connected to the LED flashing light 404. The pressure sensor 402 is powered by a built-in micro battery, which is designed to be rechargeable. The battery compartment is integrated inside the second connecting plate 401. The pressure sensor 402 is embedded inside the second connecting plate 401 at the point of contact with the ground.

[0044] The second connecting plate 401 and the second protective pad 403 are fitted together to increase friction with the ground and prevent the ladder from sliding.

[0045] The two support rods 2 are rotatably connected by the first pivot 1 and unfold into a "human" shape. The first pivot 1 is the core rotation hub of the ladder, connecting the two support rods 2 to realize the folding and unfolding functions. The first pivot 1 and the support rods 2 are set perpendicular to each other.

[0046] The outer sides of the support rods 2 are each equipped with a first anti-slip pad to prevent users from slipping. The first connecting plate 3 is connected to the support rods 2 via a foldable hinge. When the ladder is unfolded, the first connecting plate 3 can rotate or move to a horizontal position and lock, serving as a stable surface for users to step on. When folded, it can be folded up parallel to the support rods 2.

[0047] A rotating structure 5 is provided between the two support rods 2. The rotating structure 5 restricts the swaying of the support rods 2, prevents over-expansion or inward tilting, and keeps the ladder stable. The outer side of the rotating structure 5 is fixedly connected to the outer wall of the first connecting plate 3. The first connecting plate 3 is a horizontal structure that the user steps on and is fixed between the two support rods 2. When folded, it is parallel to the support rods 2.

[0048] The rotating structure 5 includes a second rotating shaft 501, a connecting rod 502, and a third rotating shaft 503. The second rotating shaft 501 is installed on the outer wall of the support rod 2. The connecting rod 502 is installed on the outer side of the second rotating shaft 501. The two connecting rods 502 are connected through the third rotating shaft 503. When the support rod 2 is extended to a safe angle, the third rotating shaft 503 integrates a self-locking cam, which engages with the corresponding structure of the connecting rod 502 to automatically lock the connecting rod 502, thereby fixing the distance between the two support rods 2 and preventing the inner side from shaking or collapsing.

[0049] The connecting rod 502 and the second rotating shaft 501 are rotatably connected.

[0050] The two connecting rods 502 are rotatably connected by a third rotating shaft 503, which serves as the pivot for the rotation of the two connecting rods 502.

[0051] The support rod 2, the first connecting plate 3, and the rotating structure 5 are all made of high-strength aluminum alloy, which is lightweight and has strong compressive strength.

[0052] Example 2:

[0053] This embodiment, based on the previous embodiment, further expands the intelligence and safety of the pressure alarm safety elevator. It aims to provide more accurate and timely risk warnings through multi-dimensional data monitoring and improve the elevator's adaptability in complex environments.

[0054] The safety ladder in this embodiment maintains the same basic structure as the first embodiment. Based on this, the following innovative improvements have been added:

[0055] Inside the second connecting plate 401 of the processing structure 4, in addition to the pressure sensor 402, the following sensor modules are additionally integrated:

[0056] Tilt sensor: Monitors the tilt angle of the ladder in real time to determine whether the ladder is within the safe tilt angle range.

[0057] Grounding status sensor: A contact sensor is integrated inside the second protective pad 403 to detect whether the ladder legs are in good contact with the ground, especially for soft ground.

[0058] Ambient light sensor: Used to sense ambient brightness and automatically adjust the brightness of LED flashing light 404 so that it can be clearly seen under different lighting conditions.

[0059] These sensors are all connected to the central control module inside the equipment via wires. The central control module performs real-time fusion analysis of the data from all sensors, providing a more comprehensive safety status assessment.

[0060] Working principle:

[0061] First, when the user unfolds the two support rods (2) through the first pivot (1), the connecting rod (502) of the rotating structure (5) will rotate synchronously around the second pivot (501) and the third pivot (503). When the support rod (2) is unfolded and reaches a safe angle, the third pivot (503) will automatically lock the connecting rod (502), thereby fixing the distance between the two support rods (2), effectively preventing the inner side from shaking or accidental collapse, and ensuring the stability of the ladder after unfolding. When it is necessary to store it, the support rod (2) is operated in the opposite direction, and the connecting rod (502) is folded up together, eventually parallel to the support rod (2). The volume is significantly reduced after folding, making it easy to store and carry. When the user steps on the first connecting plate (3), its weight is transmitted to the bottom second connecting plate (401) through the support rod (2). The pressure sensor (402) is in close contact with the second connecting plate (401), directly sensing the ground reaction force and converting the mechanical pressure into an electrical signal. The pressure sensor (402) is electrically connected to the LED flashing light (404) and is powered by a built-in battery, featuring low power consumption. When the load exceeds a preset threshold, the electrical signal immediately triggers the LED flashing light (404) to flash at high frequency, alerting the user to the risk of overload in a way that is easy to observe. This effectively prevents the ladder from breaking or tipping over due to excessive force, ensuring safe use.

[0062] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
