[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. The directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the accompanying drawings. They are only for the convenience of description and cannot be understood as limitations on the technical solution. The "first, second..." used are only used to distinguish the names and do not represent specific quantities and orders.

[0033] like Figure 1-4As shown, the utility model provides a detection device for elevator floor door, including a shell 1, a hook body 2, a processing module, a display 3, a force measuring module and a detection module. The shell 1 has a accommodating cavity, and the hook body 2 is arranged at one end of the shell 1. When in use, the hook body 2 acts on the locking element of the elevator floor door lock, and the processing module (not shown in the figure) is arranged in the accommodating cavity of the shell 1. The display 3 is exposed on the surface of the shell 1 and is electrically connected to the processing module. The force measuring module (not shown in the figure) is arranged in the accommodating cavity of the shell 1 and is electrically connected to the processing module. When in use, people hold the shell 1 tightly and pull the elevator floor door through the hook body 2. The force measuring module detects the force exerted on the hook body 2 and sends data to the processing module. The processing module receives the data and displays it through the display 3. If the pulling force is greater than 300N and the elevator floor door is still not opened, the locking efficiency of the elevator floor door meets the requirements. The detection module is electrically connected to the processing module, including a contact connector 4, the number of which is two, and also includes a speaker 5 or an indicator light 6. Specifically, the two contact connectors 4 are respectively overlapped with the two contacts on the elevator floor door locking switch. If the closing switch of the elevator floor door is short-circuited, the detected data will be sent to the display 3 through the processing module, the speaker 5 will sound an alarm, and the indicator light 6 will change. Therefore, through the above-mentioned detection device, not only can the locking efficiency of the elevator floor door door lock be detected, but also it can be determined whether the elevator floor door closing switch is short-circuited, which has the advantages of simple operation, convenience and high efficiency. It should be noted that the force measurement module and the processing module belong to the prior art in this field and are not described in detail in this article.

[0034] More specifically, as shown in the working principle of the rapid detection module, the locking switch and closing switch of each floor of the elevator are designed in series. When the second floor door is opened, the second floor locking switch is disconnected. When the closing switch is not short-circuited, Figure 5 As shown, because the second layer is locked and the second layer closed switch is in the open position, there is no potential difference between nodes 3 and 4; when the second layer closed switch is short-circuited, as shown in Figure 6 As shown, there is a 110V potential difference between nodes 3 and 4. That is, by judging the voltage across the landing door locking switch, it is possible to indirectly judge whether the landing door closing switch is short-circuited.

[0035] When the contact connector 4 of the detection module is connected to the two contacts on the elevator door locking switch, the display principle of the display circuit is as follows: Figure 7As shown, when the bonding contact L1 corresponding to the bonding contact 10 is connected to the positive pole (+) of DC power, and the other bonding contact L2 is connected to the negative pole (-) of DC power, the current passes through the current limiting resistor R1, then flows through D1, D2, R2 and the speaker LS1, and finally flows back to L2 through the high-voltage diode D5, so the green indicator lights D1 and D2 are always on and the speaker does not sound an alarm. Because the diode is forward-conducting and reverse-cutoff, the current cannot flow through D6 into D3, D4, R2 and the speaker LS2, so the red indicator lights D3 and D4 are not on and the speaker does not sound an alarm; when L2 is connected to the positive pole (+) of DC power and M1 is connected to the negative pole (-) of DC power, the current passes through D3, D4, R2 and the speaker LS2, then flows through D6, and finally flows back to L1 through the 50K current limiting resistor R1, so the red indicator lights D3 and D4 are always on and the speaker does not sound an alarm, and the green indicator lights D1 and D2 are not on and the speaker does not sound an alarm. When L1 is connected to the L pole of AC power and L2 is connected to the N pole of AC power, in the positive half axis of AC power, the current flows through the current limiting resistor R1 and then flows through D1, D2, R2 and the speaker LS1, and finally flows back to L2 through the high-voltage diode D5, so the green indicator lights D1 and D2 light up and the speaker sounds an alarm. Because the diode is forward-conducting and reverse-cutoff, the current cannot flow through D6 into D3, D4, R2 and the speaker LS2, so the red indicator lights D3 and D4 do not light up and the speaker does not sound an alarm. In the negative half axis of AC power, the current flows through D3, D4, R2 and the speaker LS2, then flows through D6, and finally flows back to L1 through the 50K current limiting resistor R1, so the red indicator lights D3 and D4 are always on and the speaker sounds an alarm. Because the diode is forward conducting and reverse blocking, the current cannot flow through D5 into D1, D2, R2 and speaker LS1, so the green indicator lights D1 and D2 are not on. When L2 is connected to the L pole of the AC power and L1 is connected to the N pole of the AC power, it can be analyzed by analogy. So when detecting AC power, in theory, D1, D2, D3 and D4 flash alternately. Because the AC power frequency is 50Hz, the human eye cannot distinguish that the LED is flashing alternately. In fact, what we see is: when testing AC power, we will see that the red LEDs D1 and D2 and the green LEDs D4 and D5 are always on. The above detected data will be processed by the processing module and displayed in the display 3.

[0036] In a specific embodiment, the detection module also includes an adjustment button 7, which is exposed on the surface of the shell 1. The adjustment button 7 is used to adjust the length of the contact connector 4, so as to facilitate the overlap of the contact connector 4 with the two contacts on the elevator door locking switch.

[0037] In a specific embodiment, the detection device for elevator landing doors further includes a data storage module, which is disposed in the accommodating cavity of the housing 1 and is electrically connected to the processing module. Under the action of the data storage module, the detected data can be stored, so as to better understand the state of the elevator landing doors.

[0038] In a specific embodiment, the detection device for the elevator landing door further includes a pull ring 8, which is arranged at the other end of the housing 1. Since the housing 1 is relatively large, it is not convenient for people to hold it tightly when using the detection device. However, the pull ring 8 makes it easier for people to pull the elevator landing door.

[0039] In a specific embodiment, the detection device for the elevator floor door can be directly connected to the power supply. However, in order to facilitate people's use, the detection device of the utility model is preferably provided with a lithium battery, and the lithium battery is arranged in the accommodating cavity of the shell 1, and the lithium battery is used to provide power for the detection device.

[0040] In a specific embodiment, the display 3 is provided with a control button 9, and the control button 9 is exposed on the upper surface of the housing 1. Through the control button 9, people can control the display 3 to be turned on or off, and can also set the function of the display.

[0041] In a specific embodiment, the hook body 2 and the pull ring 8 can both rotate 360° along their own central axis, so as to facilitate the force measurement module to transmit the force. The housing 1 is made of metal material, and the metal material is preferably stainless steel, so as to improve the durability of the housing 1.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
