[0039] In order to further illustrate the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments of the present application are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0040] Please refer to Figures 1 to 3 The embodiment of the present application provides a quick multi-blade switch, which comprises a multi-blade switch body 100, the multi-blade switch body 100 comprising:

[0041] a rotating trigger assembly 1;

[0042] an on-trigger assembly 2, which is driven to rotate by the rotating trigger assembly 1;

[0043] A PCB board 3 is provided with a code disc 31 and at least one output end 32. The code disc 31 is divided into several areas, specifically, six areas in the embodiment, i.e. A area, B area, C area, D area, E area and F area. Each area has a common end and a conductive area corresponding to the common end. The conductive area is provided with several spaced-apart conductive contacts. Specifically, the conductive area of each area is provided with four conductive contacts in the embodiment. Specifically, the A area has a common end A0 and conductive contacts A1-A4, the B area has a common end B0 and conductive contacts B1-B4, the C area has a common end C0 and conductive contacts C1-C4, the D area has a common end D0 and conductive contacts D1-D4, the E area has a common end E0 and conductive contacts E1-E4, and the F area has a common end F0 and conductive contacts F1-F4. The output end 32 is provided with several output end points. The common ends and the conductive contacts of the several areas are respectively electrically connected to the output end points one by one through a wire. Specifically, the number of the output end 32 is two, and the two output ends 32 are oppositely arranged on the two sides of the PCB board 3. When the code disc is divided into six areas and the conductive area of each area is provided with four conductive contacts, the common end and the conductive contacts of each area need to be electrically connected to five output end points respectively, and a total of 30 output end points are needed, i.e. 30 output end points need to be provided on the output end 32.

[0044] As shown in Figure 3 , the common ends and the conductive contacts of each area are connected to the output end points with the same mark through wires (not shown in the figure). For example, the common end A0 is connected to the output end point A0 through a wire, the conductive contact A1 is connected to the output end point A1 through a wire, the conductive contact A2 is connected to the output end point A2 through a wire, the conductive contact A3 is connected to the output end point A3 through a wire, and the conductive contact A4 is connected to the output end point A4 through a wire.

[0045] As can be seen from the structural design of the code disc 31 and the output end 32, the several conductive contacts of the conductive area of each area correspond to several gears, i.e. four conductive contacts correspond to four gears.

[0046] In the embodiment, the common ends and the conductive contacts of each area are triggered to conduct by the conduction trigger assembly 2. When the conduction trigger assembly 2 triggers the conduction between the common ends and the conductive contacts of each area, one gear in each area of the code disc 31 can be triggered to conduct at the same time, for example, when the code disc is divided into six areas, four gears can be triggered to conduct at the same time, i.e. six signals can be output by the output end 32 at the same time, which are used to control six components and realize six functions. At the same time, there are six areas on the code disc, so the switch product is called a six-blade switch.

[0047] Of course, the number of regions on the code disc 31, the number of conductive contacts on each conductive region, and the number of output terminals 32 can be set according to specific needs, and the above examples are merely for the convenience of explanation.

[0048] In the present embodiment, as shown in Figure 3 , the common terminals (A0, B0, C0, D0, E0, F0) are arc-shaped, and the common terminals are independent structures, which are clear and distinct; the plurality of conductive contacts (A1-A4, B1-B4, C1-C4, D1-D4, E1-E4, F1-F4) on the conductive regions are fan-shaped distributed outside the common terminals (A0, B0, C0, D0, E0, F0), and the common terminals (A0, B0, C0, D0, E0, F0) of the plurality of regions enclose to form an inner circle, and the conductive regions of the plurality of regions enclose to form an outer circle.

[0049] In the present embodiment, as shown in Figure 2 , Figure 4 and Figure 5 , the conductive trigger assembly 2 includes a rotating disc 21 connected to the rotating trigger assembly 1, and a plurality of conductive tabs 22 arranged on the rotating disc 21 and in contact with the code disc 31. Specifically, the plurality of conductive tabs 22 are annularly distributed on the lower end surface of the rotating disc 21. When the rotating trigger assembly 1 drives the rotating disc 21 to rotate, the plurality of conductive tabs 22 rotate with the rotating disc 21, and then the plurality of conductive tabs 22 annularly slide on the code disc 31, thereby triggering the conduction between the common terminals of each region on the code disc 31 and the different conductive contacts on the corresponding conductive regions, i.e. the conductive tabs 22 play the role of electrically connecting the common terminals and the conductive contacts, thereby realizing the conduction of different gears on each region. Thus, each region can output a signal for controlling different components to achieve different functions.

[0050] Specifically, as shown in Figure 4 , the conductive tab 22 mainly includes a connecting block 221 arranged on the rotating disc 21, and a first conductive tab arm 222 and a second conductive tab arm 223 respectively connected to the connecting block 221 and extending obliquely towards the code disc 31, wherein a conductive contact (2221, 2231) is formed at the end of the first conductive tab arm 222 and the second conductive tab arm 223 respectively, the conductive contact 2221 of the first conductive tab arm 222 is in sliding contact with the conductive region of the outer circle, and the conductive contact 2231 of the second conductive tab arm 223 is in sliding contact with the common terminal of the inner circle. In the present embodiment, the connecting block 221 can be directly welded to the rotating disc 21. Specifically, for the number of conductive tabs 22, when the code disc is divided into six regions, the number of corresponding conductive tabs 22 is six. The six conductive tabs 22 respectively control the conduction between the common terminals on the six regions and the different conductive contacts on the corresponding conductive regions.

[0051] When the conducting spring 22 slides on the code disc 31 in a ring shape, there is one conducting spring 22 sliding on each region, as shown in the figure, the conducting contact 2221 of the first conducting spring arm 222 slides on the conductive area of the outer circle, and the conducting contact 2231 of the second conducting spring arm 223 slides on the common end of the inner circle, thereby triggering the conduction between the common end of each region and the different conductive contacts on the corresponding conductive area by the conducting spring 22, and when the conducting spring 22 turns to the designated position, a specific set of signals can be output. Figure 5

[0052] In this embodiment, as shown in the figure, the rotating trigger assembly 1 includes a driving shaft 11 and a switch handle 12 connected to the upper end of the driving shaft 11, wherein the rotating disc 21 is sleeved on the periphery of the driving shaft 11. By rotating the switch handle 12, the driving shaft 11 is driven to rotate, which in turn drives the rotating disc 21 to rotate synchronously, thereby realizing the sliding of the conducting spring 22 on the code disc 31 and outputting multiple sets of signals. Figure 2

[0053] The PCB board 3 provided in this embodiment has various combinations of output signals, a total of 16777216 combinations, which can meet the arbitrary needs of customers, as shown in Table 1.

[0054]

[0055]

[0056] Table 1

[0057] From the above Table 1, it can be seen that the output signal and the non-output signal, i.e. the signal output and the non-signal output of the output end 32 of the PCB board 3, the non-signal output state can be realized in the following three ways:

[0058] (1) The conductive wire between the conductive contact on the corresponding gear of the corresponding region and the output end point is removed in advance, so that there is always no signal output;

[0059] (2) The pin in the jack 321 of the following output end 32 is pulled out in advance, so that there is always no signal output, and the output end point at the position of the pulled-out pin and the conductive contact on the corresponding gear of the corresponding region are connected by a conductive wire.

[0060] (3) When the conducting contact 2221 of the first conducting spring arm 222 on the conducting spring 22 slides away from the conductive contact on the gear, the conductive contact on the gear and the common end are disconnected, so that there is no signal output.

[0061] ​​Since the PCB board 3 can output different specific signals, it can be used to control various components and realize various functions, so as to meet the various needs of customers and facilitate various operation controls during on-site maintenance and debugging of the rail transit shield door, such as opening of the shield door, closing of the shield door, alarm, etc.

[0062] In order to facilitate the installation of the multi-blade switch body 100, the following three structures are provided in the embodiment to realize three installation modes.

[0063] (1) A plurality of jacks 321 corresponding to the output end points are formed on the output end 32, as shown in Figure 3 . In this way, the multi-blade switch body 100 can be directly inserted and welded on the control panel in the equipment (rail transit shield door). Specifically, as long as the corresponding pins on the control panel are inserted into the jacks 321 on the output end 32 and welded, the pins on the control panel and the output end points on the output end 32 are electrically connected one by one.

[0064] (2) Based on the structure of the above (1), as shown in Figure 1 and Figure 5 , a pin group 33 is inserted on the output end 32, which is composed of a plurality of pins 331 inserted into the jacks 321 and welded on the output end points. At the same time, a docking socket 201 is welded on the control panel 200 in the equipment (rail transit shield door). As shown in Figure 6 , two docking sockets 201 are arranged on the control panel 200 corresponding to the two output ends 32. During installation, the pin group 33 of the multi-blade switch body 100 is directly inserted into the docking socket 201.

[0065] (3) An installation positioning structure 5 is arranged on the multi-blade switch body 100, which is a combination of a plurality of studs 51 and nuts 52, or a plurality of supports 53. The multi-blade switch body 100 is directly positioned and installed in the equipment (rail transit shield door) by the installation positioning structure 5. Then, the output end 32 is connected to the outside through the plug-in interface and plugged into the corresponding control panel. Of course, another installation mode can be realized by combining the above (2) structure, that is, the multi-blade switch body 100 can be positioned or plugged, as shown in Figure 7 .

[0066] As can be seen from the above (1) to (3) structures and installation modes, the multi-blade switch provided in the embodiment can balance the installation on the control panel according to the actual needs on site, and directly control the target. The installation mode is various, convenient and fast, with high installation precision and small error. Moreover, the disassembly is also convenient and fast, with small difficulty, time and labor saving, and convenient for replacement of the switch product.

[0067] In the embodiment, a silk screen panel 6 is arranged on the multi-blade switch body 100 and can be selectively installed according to the use requirement. The silk screen panel 6 can be silk-screened with scales or patterns, etc. to play a role of marking and indicating, facilitating the control of the rotation range of the switch handle 12 in the trigger assembly 1 and the control and debugging of the shielding door.

[0068] In the embodiment, the overall height of the multi-blade switch body 100 is less than 60 mm and the width is less than 55 mm, the volume is small, the required installation space is small, the narrow installation space of the shielding door can be adapted, the structure is compact, and the application is more flexible. The installation reserved size and the opening requirement are lower, and the variable installation environment can be better adapted.

[0069] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application in any way. Therefore, other structures obtained by using the same or similar technical features as the above-mentioned embodiments of the present application are within the protection scope of the present application.
