To ensure personnel safety and a clean environment, door opening alarms are installed on the door frame and door body. A Chinese patent application, publication number CN214365555U, discloses a magnetic door stopper with a switch. This switch uses springs to trigger three contact points at different locations, increasing safety. However, this structure is bulky and inconvenient to install. Furthermore, the springs trigger three different contact points, requiring them to reach specific contact points at different door opening states. This makes the springs susceptible to fatigue and requires high processing requirements. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3 As shown, a door-touching trigger device includes a mounting base 1, the mounting base 1 includes a trigger side 16, the trigger side 16 is provided with a magnetic part 2, a core shaft 3, an elastic part 4 and a micro switch 5 are provided in the mounting base 1, one side of the micro switch 5 is provided with a contact 6, and one side of the contact 6 is correspondingly provided with a core shaft 3, the elastic part 4 abuts between the core shaft 3 and the micro switch 5, and the end of the core shaft 3 extends to the outside of the trigger side 16. The magnetic part 2 and the micro switch 5 are arranged on the mounting base. When closing the door, the door body is adsorbed and fixed by the magnetic part 2, and the core shaft 3 abuts against the contact 6 of the micro switch 5 to trigger the signal of the micro switch 5. When opening the door, the door body is pulled to release the magnetic attraction, and the elastic part 4 pushes the core shaft 3 to reset, and the contact signal of the micro switch 5 becomes a non-contact signal. The micro switch responds quickly and can be opened faster. After obtaining the signal that the door is opened, the controller controls the automation equipment to alarm and shut down, with a high safety factor; the contact 6 of the micro switch 5 is triggered by the core shaft 3, and only the triggering position needs to reach the characteristic contact point position. The core shaft 3 is easy to process, and the core shaft 3 is reset by the elastic member 4. When resetting, it is only necessary to ensure that the core shaft 3 no longer triggers the micro switch 5 and the end of the core shaft 3 extends to the outside of the trigger side 16. This position does not require particularly precise triggering, and the processing accuracy requirement is lower than that of the shrapnel that needs to accurately trigger three positions; by placing the elastic member 4, the core shaft 3 and the magnetic member 2 in sequence on one side of the contact 6 of the micro switch 5 and then encapsulating the mounting base 1, it is convenient to assemble, and no large space is required in the mounting base to complete the installation. The core shaft 3 only needs to move a certain distance axially to complete the signal triggering, and the overall structure is compact.

[0025] There are two micro switches 5, and the contacts 6 of the two micro switches 5 are both arranged on one side of the core shaft 3. The contacts 6 are all arranged corresponding to the end face of the core shaft 3. Two micro switches 5 are installed. When one set of contacts 6 fails, the other set of contacts 6 can still work, which plays a role of double protection, meets the 3C certification requirements, and improves the safety factor. Since the stroke of the core shaft 3 is very small, almost the stroke of the micro switch 5, the micro switch 5 will be activated as long as the safety door is opened a little, thereby realizing an alarm and a faster response speed.

[0026] The elastic member 4 is a rubber spring, which is low in cost and easy to assemble. It has a good reset function and can realize the reset of the core shaft 3. The rubber spring can absorb the impact force when partially closing the door and transfer the impact force to the housing of the micro switch 5 to prevent damage to the contact 6.

[0027] The core shaft 3 is T-shaped, and a groove 7 is provided at the bottom of the core shaft 3. One end of the elastic member 4 abuts in the groove 7, and the other end abuts against the end face of the micro switch 5. The groove 7 is convenient for installing the elastic member 4.

[0028] The mounting base 1 is provided with a mounting hole 8 for easy assembly. The locking piece is passed through the mounting hole 8, and the lower bottom surface of the mounting base 1 is aligned with the door frame, and the trigger side 16 is aligned with the door panel, so that the core shaft 3 can contact the door panel when closing the door, triggering the micro switch 5.

[0029] The magnetic member 2 is sleeved on the core shaft 3 , and a buffer member 9 is provided between the mounting seat 1 and the magnetic member 2 . The buffer member 9 is sleeved on the core shaft 3 to achieve noise reduction and buffering of impact on the micro switch 5 .

[0030] The mounting base 1 includes a front sealing plate 10 and a rear sealing plate 11. The front sealing plate 10 is arranged on the peripheral side of the magnetic part 2. The front sealing plate 10 is used to fix the magnetic part 2 in the mounting base 1. The rear sealing plate 11 is arranged at the rear of the micro switch 5 for easy assembly. The micro switch 5 is encapsulated in the mounting base 1 by the front sealing plate 10 and the rear sealing plate 11, which reduces the influence of external factors such as disinfection chemicals on the micro switch 5 and improves reliability.

[0031] The mounting base 1 is injection molded to achieve waterproofing and reduce manufacturing costs.

[0032] like Figure 4 As shown, a safety door includes a door frame 12 and a door body 13. The door frame 12 is installed with the door collision trigger device as described above, and the door body 13 is provided with a door collision plate 14 corresponding to the door collision trigger device. The interior of the door frame 12 is provided with a wiring channel 15 to facilitate installation and improve the safety factor.
