[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of an emergency alarm device for freight elevators provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the elastic support component. Figure 3 for Figure 1 The diagram shows the structure of the alarm device. Figure 4 for Figure 1 The diagram shows the structure of the sliding component. Figure 5 for Figure 1 The diagram shows the structure of the buffer baffle. An emergency alarm device for a freight elevator includes: a supporting sliding frame assembly 1 and an alarm device 2. The alarm device 2 is installed on the top inner wall of the supporting sliding frame assembly 1. Elastic supporting components 3 slide at both ends of the supporting sliding frame assembly 1 for elastic support of the alarm device 2. A position sliding component 4 slides on the inner wall of the supporting sliding frame assembly 1. Limiting active components 5 are provided at both ends of the position sliding component 4 for limiting the sliding of the elastic supporting components 3. A buffer component 6 is installed on the top of the position sliding component 4 for position buffering of the alarm device 2.

[0023] The supporting sliding frame assembly 1 includes a sliding adjustment frame 11. The inner wall of the sliding adjustment frame 11 is provided with a cable fixing groove 12 for the installation of the alarm device 2 cable. The two ends of the sliding adjustment frame 11 are provided with sliding vertical grooves 13 for limiting the sliding of the active component 5. The two ends of the sliding adjustment frame 11 are provided with fastening plates 14.

[0024] The sliding adjustment frame 11 can support the position of the internal alarm device 2, reducing workpiece deviation during use. In addition, the cable fixing groove 12 and sliding vertical groove 13 on the side can facilitate the sliding installation of the required structure.

[0025] Among them, the supporting slide frame assembly 1 includes, but is not limited to, metal guide rail slide frame and aluminum alloy profile slide frame; in this embodiment, the supporting slide frame assembly 1 is preferably an aluminum alloy profile slide frame.

[0026] The elastic support assembly 3 includes a limiting slider 31, a rotating frame 32 is installed inside the limiting slider 31, a support baffle 33 is rotatably mounted on the side of the rotating frame 32, and a return spring 34 is provided at both ends of the support baffle 33 for resetting the position of the support baffle 33. An elastic positioning element 35 is provided on the side of the limiting slider 31 for elastic positioning of the limiting slider 31.

[0027] When retracting the position support of the alarm device 2, the support baffle 33 can be rotated along the position of the rotating frame 32. Under the gravity of the alarm device 2, the position support installation can be carried out. Furthermore, the elastic positioning member 35 provided on the side will be locked to the inner walls of both ends of the support slide frame assembly 1 for further elastic support to reduce workpiece deviation during use. Subsequently, when retracting, the rotating support baffle 33 will be elastically reset by the return spring 34 to retract the workpiece. In addition, the limit active assembly 5 will retract the elastic positioning member 35 on the side to ensure convenient retraction of the limit slider 31.

[0028] Among them, the elastic support component 3 includes, but is not limited to, a compression spring structure and a pneumatic support structure; in this embodiment, the elastic support component 3 is preferably a compression spring structure.

[0029] The position sliding component 4 includes a sliding baffle 41, a fixed handle 42 is installed on the side of the sliding baffle 41 for limiting the sliding of the workpiece of the active component 5, and support baffles 43 are fixed at both ends of the sliding baffle 41 for limiting the position support of the active component 5.

[0030] When the alarm device 2 at the top is slidable, the position of the sliding baffle 41 can be easily adjusted by using the fixed handle 42, thereby improving the ease of use of the device and reducing the limitation of the workpiece that prevents the structure from shrinking.

[0031] The limiting active component 5 includes an extension support rod 51, with an inclined limiting block 52 installed on the top of the extension support rod 51 for sliding and retracting the elastic support component 3. The two ends of the extension support rod 51 are equipped with mounting sleeves 53 for positional installation of the extension support rod 51.

[0032] When the top elastic support component 3 is slid and retracted, the inclined surface of the top inclined limiting block 52 will structurally limit the elastic support component 3. Subsequently, the other side of the inclined limiting block 52 will retract the elastic structure to facilitate the retraction and sliding of the elastic support component 3.

[0033] Among them, the active limiting component 5 includes, but is not limited to, an electromagnetic limiting structure and a manual mechanical limiting structure; in this embodiment, the active limiting component 5 is preferably a manual mechanical limiting structure.

[0034] The buffer assembly 6 includes an elastic buffer rod 61, and a buffer baffle 62 is installed on the top of the elastic buffer rod 61 for position buffering of the alarm device 2. A sponge pad layer 63 is installed on the top of the buffer baffle 62.

[0035] When the alarm device 2 at the top slides downwards, the buffer baffle 62 at the bottom is elastically supported by the elastic buffer rod 61 to reduce workpiece damage during sliding.

[0036] The buffer component 6 includes, but is not limited to, a rubber buffer pad and a spring damping structure; in this embodiment, the buffer component 6 is preferably a spring damping structure.

[0037] The working principle of the emergency alarm device for freight elevators provided by this utility model is as follows:

[0038] During daily use, the alarm device can be activated by pressing the internal alarm device 2. When a user falls, the internal sliding component 4 can be slid downwards. As the sliding component 4 slides downwards, the limiting active components 5 at both ends restrict the elastic support component 3. Subsequently, the elastic support component 3 will retract. When the internal structure retracts, it will not support the inner wall of the side of the support slide frame component 1, and the alarm device 2 at the top will automatically slide downwards to facilitate the user to press the alarm device 2 in time for warning. At the same time, when the alarm device 2 slides, the buffer component 6 at the bottom will cushion the position of the alarm device 2 to reduce damage caused by collisions during use.

[0039] Compared with related technologies, the emergency alarm device for freight elevators provided by this utility model has the following advantages:

[0040] Beneficial effects:

[0041] To enhance the ease of operation during daily use, the alarm device incorporates a flexible support component 3 and a limiting active component 5. This allows the top alarm device 2 to automatically slide downwards, enabling easy activation of the alarm even if someone falls. This significantly shortens the alarm response time, providing valuable time for timely rescue and greatly improving the success rate of emergency alarms, effectively protecting the lives of trapped individuals. Simultaneously, the bottom buffer component 6 provides cushioning support during the sliding motion of the alarm device 2, reducing the risk of internal component loosening or casing damage due to impacts, thus minimizing disruption to normal operation and lifespan.
