[0036] The following is a detailed description of a device for collecting synchronous emergency stop trigger signals according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0037] like Figures 1 to 3 As shown, the acquisition device for synchronous emergency stop trigger signal according to the embodiment of the utility model includes a housing 10 , a trigger pole piece 20 , a pole piece trigger ring 30 , a trigger button 40 and a buffer assembly 50 .

[0038] Specifically, a housing 10 defines a housing cavity 11, and the housing 10 is used to be arranged on the emergency stop button. The trigger pole piece 20 is arranged in the housing cavity 11 and is located at the bottom of the housing cavity 11. The pin of the trigger pole piece 20 can extend out of the housing 10 to connect to an external device. The pole piece trigger ring 30 is arranged in the housing cavity 11, and the pole piece trigger ring 30 is movable toward the trigger pole piece 20. The trigger button 40 is arranged at the top of the housing 10, and a part of the trigger button 40 extends into the housing cavity 11. The buffer assembly 50 is arranged in the housing cavity 11, and the buffer assembly 50 is located between the trigger button 40 and the pole piece trigger ring 30. The trigger button 40 is connected to the buffer assembly 50. The buffer assembly 50 and the pole piece trigger ring 30 have a movable space along the axial direction of the housing 10. When the trigger button 40 moves, the pole piece trigger ring 30 and the trigger pole piece 20 can contact or disconnect.

[0039] In other words, if Figures 1 to 3 As shown, the acquisition device for synchronous emergency stop trigger signal according to the embodiment of the utility model is mainly composed of a housing 10, a trigger pole piece 20, a pole piece trigger ring 30, a trigger button 40 and a buffer component 50. Figure 3 As shown, a receiving chamber 11 is provided in the housing 10, and the housing 10 can be directly arranged on the upper part of the emergency stop button. Figure 1 and Figure 2 As shown, the trigger pole piece 20 is installed in the accommodating cavity 11, and the trigger pole piece 20 is located at the bottom of the accommodating cavity 11. The pins of the trigger pole piece 20 can extend out of the housing 10 to connect to an external device, so as to facilitate reading the connection status of the trigger pole piece 20. The pole piece trigger ring 30 is installed in the accommodating cavity 11, and the pole piece trigger ring 30 is movable toward the trigger pole piece 20 to achieve contact or disconnection with the trigger pole piece 20.

[0040] like Figure 1 As shown, the trigger button 40 is installed on the top of the housing 10, and a part of the trigger button 40 can extend into the accommodating cavity 11. By rotating the trigger button 40, the height of the pole piece trigger ring 30 relative to the bottom plane of the trigger button 40 is adjusted. The buffer assembly 50 is installed in the accommodating cavity 11, and the buffer assembly 50 is located between the trigger button 40 and the pole piece trigger ring 30. The trigger button 40 is connected to the buffer assembly 50, and the buffer assembly 50 and the pole piece trigger ring 30 have a movable space along the axial direction of the housing 10. When the trigger button 40 is active, the pole piece trigger ring 30 and the trigger pole piece 20 can be in contact or disconnected. Under the action of the trigger button 40 and the buffer assembly 50, the pole piece trigger ring 30 can move toward the trigger pole piece 20. During the triggering process of the emergency stop button, the pole piece trigger ring 30 will not block the pressing of the emergency stop button. At the same time, the pole piece trigger ring 30 and the trigger pole piece 20 can be turned on and output a switch signal for processing by the lower-level device.

[0041] The acquisition device of the utility model adopts a non-intrusive signal acquisition method, which effectively avoids the risk of hardware disassembly and is isolated from the original circuit of the equipment, so it is highly safe. The emergency stop signal is collected non-invasively to avoid modifying the original system, reducing the difficulty and risk of operation. By using the emergency stop signal as a trigger condition, synchronous transmission with other device signals is achieved to improve measurement accuracy and reliability. It is also suitable for measurement scenarios of high-speed moving objects to meet the needs of real-time execution of other processes. The existing emergency stop trigger signal can only be collected through button contacts, and the external device or temporary test collection of the emergency stop signal requires the signal acquisition circuit to be incorporated into the emergency stop control circuit. In addition, the external device is required to adapt the trigger signal voltage, which may have a certain impact on the original circuit scheme of the equipment, and there is also a certain risk associated with hardware disassembly.

[0042] The acquisition device of the utility model can reduce the trigger delay, and the test accuracy and reliability are high. The existing emergency stop signal acquisition generally relies on human sensory judgment and acquisition, which has certain errors, and after the signal is acquired, it is impossible to synchronize the lower-level equipment in time to perform data acquisition or other actions.

[0043] At the same time, the movable space between the trigger button 40 and the buffer assembly 50 of the acquisition device of the utility model is adjustable. Through the cooperation of the trigger button 40 and the buffer assembly 50, the key travel between the pole piece trigger ring 30 and the trigger pole piece 20 can be adjusted, which is convenient for adapting to a variety of emergency stop buttons with no trigger key travel.

[0044] Therefore, according to the acquisition device for synchronous emergency stop trigger signal of the embodiment of the utility model, by rotating the trigger button 40, the height of the pole piece trigger ring 30 relative to the bottom plane of the trigger button 40 is adjusted. Under the action of the trigger button 40 and the buffer assembly 50, the pole piece trigger ring 30 can move toward the trigger pole piece 20. During the triggering process of the emergency stop button, the pole piece trigger ring 30 will not block the pressing of the emergency stop button. At the same time, the pole piece trigger ring 30 and the trigger pole piece 20 can be connected to output a switch signal for processing by the lower-level equipment. The acquisition device of the utility model adopts a non-intrusive signal acquisition method, effectively avoids the risk of hardware disassembly, and forms isolation with the original circuit of the equipment, with high safety. At the same time, the acquisition device can reduce the trigger delay, and the accuracy and reliability of the test are high. In addition, the movable space between the trigger button 40 and the buffer assembly 50 of the acquisition device is adjustable. Through the cooperation of the trigger button 40 and the buffer assembly 50, the key travel between the pole piece trigger ring 30 and the trigger pole piece 20 can be adjusted, which is convenient for adapting to a variety of emergency stop buttons that do not form a trigger key travel.

The bottom of the housing 10 is provided with a mounting groove 13, and the trigger pole piece 20 is embedded in the mounting groove 13 to ensure the stability of the installation of the trigger pole piece 20 at the bottom of the housing 10.

[0047] According to an embodiment of the utility model, the acquisition device for synchronous emergency stop trigger signal further includes: a first elastic member 60, which is sleeved on the side of the trigger button 40 facing the pole piece trigger ring 30, and the first elastic member 60 is stopped on the top surface of the housing 10. The first elastic member 60 can be a button return spring.

[0048] In other words, Figure 1 and Figure 2 As shown, the acquisition device for synchronous emergency stop trigger signal also includes: a first elastic member 60, which can be sleeved on the side of the trigger button 40 facing the pole piece trigger ring 30. And the first elastic member 60 can stop on the top surface of the housing 10, and the pressing and resetting of the trigger button 40 are achieved through the first elastic member 60. The first elastic member 60 can be a button return spring, which has a simple structure and is convenient for pressing and resetting the trigger button 40.

[0049] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the buffer assembly 50 includes a buffer 51 and a second elastic member 52.

The circumference of the first buffer body 511 is provided with a plurality of grooves 513, and the inner wall surface of the housing 10 is provided with a plurality of protrusions 14 extending along the axial direction thereof. The first buffer body 511 is correspondingly connected to the protrusions 14 through the grooves 513. The first buffer body 511 is provided with an internal thread, and the trigger button 40 is provided with an external thread. A part of the trigger button 40 extends into the first buffer body 511 and is threadedly connected to the first buffer body 511. The second elastic member 52 is a buffer spring.

[0050] That is to say, Figure 1 and Figure 2As shown, the buffer assembly 50 is mainly composed of a buffer 51 and a second elastic member 52. The buffer 51 is installed in the accommodating cavity 11, and the buffer 51 is movable relative to the axial direction of the housing 10. The second elastic member 52 is connected to the buffer 51, and a part of the second elastic member 52 stops the pole piece trigger ring 30. The buffer 51 includes a first buffer body 511 and a second buffer body 512, wherein the radial dimension of the first buffer body 511 is greater than the radial dimension of the second buffer body 512, and the second elastic member 52 can be sleeved on the second buffer body 512. The circumference of the first buffer body 511 can be provided with a plurality of grooves 513, and the inner wall surface of the housing 10 can be provided with a plurality of protrusions 14 extending along the axial direction thereof, and the first buffer body 511 is correspondingly connected to the protrusions 14 through the grooves 513. The first buffer body 511 is provided with an internal thread, and the trigger button 40 is provided with an external thread, and a part of the trigger button 40 can extend into the first buffer body 511 and be threadedly connected with the first buffer body 511. The second elastic member 52 may be a buffer spring.

[0051] In the present utility model, if Figures 1 to 3 As shown, the trigger pole piece 20 is embedded in the bottom of the housing 10, and the pin of the trigger pole piece 20 can be connected to the wire and led out of the housing 10, so that the external device can read the pole piece connection status. The first elastic member 60 serves as a reset spring on the trigger button 40, and the concave (groove 513) of the buffer member 51 is engaged with the inner wall column (convex column 14) of the housing 10, and the trigger height is adjusted in conjunction with the internal thread of the trigger button 40. The buffer spring (second elastic member 52) is embedded in the buffer member 51, and is embedded in the buffer member 51 in conjunction with the pole piece trigger ring 30, and can meet the up and down movement of the pole piece trigger ring 30.

[0052] The specific triggering function of the acquisition device of the utility model is as follows: the acquisition device can be directly covered on the upper part of the emergency stop button, and the height of the pole piece trigger ring 30 relative to the bottom plane of the trigger button 40 can be adjusted by rotating the trigger button 40, and the emergency stop button is determined to be pressed down to the untriggered position (the trigger pole piece 20 and the pole piece trigger ring 30 are not in contact), and the height adjustment of the buffer component 50 is completed.
