[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] like Figures 1 to 13As shown, the utility model provides a centralized control operation keyboard with an upper cover that can be opened and stopped at any time, including an upper cover plate 1 and a lower shell 2. The end of the upper cover plate 1 and the corresponding end of the lower shell 2 are connected by a hinge, so that the upper cover plate 1 can be flipped up and opened and closed at will, and the other end of the upper cover plate 1 and the other end of the lower shell 2 are detachably connected by screws. The main control board 10 and the serial port adapter board 20 are installed on the lower shell 2, and the main control board 10 and the serial port adapter board 20 are electrically connected. The bottom of the upper cover plate 1 is installed with an independent key board 11 and a matrix key board 12, and the top of the upper cover plate 1 is installed with a key 13, which is inserted into the upper cover plate 1. When the upper cover plate 1 and the lower shell 2 are closed, when the key 13 is pressed, the end of the key 13, the independent key board 11 and the matrix key board 12 are in contact with the main control board 10.

[0029] In order to ensure the universality of the keypad in different keyboards, the keypad adopts anisotropic design when determining the external dimensions of the keypad, taking into full consideration the size limitations caused by the different key layouts in each operating keyboard. The length and width of the keyboard are 600mm×400mm, which is greatly reduced compared to the original operating keyboard.

[0030] like Figure 2 and Figure 3 As shown, a stop-gas strut 3 is provided between the upper cover plate 1 and the lower shell 2. The number of the stop-gas struts 3 is two and they are arranged in parallel. The stop-gas struts 3 are Su Shibo stop-gas struts with a support force of 60N. The stop-gas struts 3 allow the upper cover plate 1 to arbitrarily hover between 30° and 85°. In this embodiment, the stop-gas struts 3 are existing stop-gas strut equipment, which can stop the upper cover plate 1 within a set angle according to actual use needs.

[0031] In this embodiment, the hinges are movable hinges, and there are two of them. The movable hinge is an existing connection method, which enables the upper cover 1 to be flipped up and opened and closed at will. The structure of the utility model allows the upper cover 1 to be suspended at a desired angle when installing and repairing internal electrical components, which is convenient for personnel to operate.

[0032] like Figures 4 to 6 As shown, a lower shell flash 21 is provided on the outer sides of the lower shell 2, and a polyurethane flat foam sealant 14 is coated on the upper cover 1, and the foam sealant 14 expands up to 10 mm; after the upper cover 1 is closed and the screws on the upper cover 1 are tightened, the foam sealant 14 of the upper cover 1 is in close contact with the lower shell flash 21 of the lower shell 2, and the foam sealant 14 is compressed, so that the lower shell 2 is sealed.

[0033] In this embodiment, the cross section of the lower shell flash 21 is a "C" shaped structure. The foam sealant 14 contacts the top of the lower shell flash 21 and can achieve a sealing effect under the action of pressure.

[0034] The screws on the upper cover plate 1 are M5 countersunk screws, and the number is 5. The keys 13 are all keys with a protection level of at least IP65, and the overall protection level of the keyboard can reach IP65.

[0035] The joints at the ends of the upper cover 1 and the lower shell 2 are respectively concave to form hand-gripping grooves, and the size parameters of the hand-gripping grooves are: length 100mm, height 20mm, and depth 8mm. When the operator puts both fingers into the hand-gripping grooves, because the fingers do not contact the lower shell flash 21 of the lower shell 2 when putting down the upper cover 1, the risk of fingers being pressed when closing the upper cover 1 is eliminated. By setting the hand-gripping grooves, it is convenient for operators to use.

[0036] Two first threaded holes 22 are respectively provided on both sides of the lower shell 2, and four second threaded holes 23 are provided on the bottom of the lower shell. Both the first threaded holes 22 and the second threaded holes 23 are countersunk holes, and blind holes of the M10 model.

[0037] During actual use of the utility model, when the operation keyboard of the utility model is fixed on an existing centralized control center or operating table, the operation keyboard is fixed by cooperating with the first threaded hole 22 and the second threaded hole 23 through the existing M10 screws on the operating table.

[0038] A lower shell back groove is provided on the back of the lower shell 2, and the size parameters of the lower shell back groove are: length 180mm, height 42mm, depth 23mm; an M12 square connector 24 and an RJ45 metal connector 25 are installed in the lower shell back groove, the M12 square connector 24 is connected to the main control board 10, and the RJ45 metal connector 25 is connected to the serial port adapter board 20, the M12 square connector 24 and the RJ45 metal connector 25 can not protrude to the outside of the lower shell, and the M12 square connector 24 and the RJ45 metal connector 25 both have an IP65 protection grade.

[0039] In this embodiment, the operation keyboard of the utility model uses an M12 square connector 24 to connect the existing 12V DC power to the keyboard to power the operation keyboard. The main control board 10 uses RS422 / 485 bus communication, and the serial port adapter board 20 converts the RS422 / 485 communication bus into an Ethernet signal, which is connected to an external switch through an RJ45 metal connector 25 installed on the lower housing 2. The main control board 10 can communicate with an existing external host computer.

[0040] A fixing part 26 is provided inside the lower housing 2, and the fixing part 26 is located at the front part of the lower housing 2. A buzzer 27 is installed between the fixing parts 26, and the buzzer 27 has a protection level of IP68. A sealing ring 28 is sleeved on the buzzer 27, and the sealing ring 28 abuts against the fixing part 26 of the lower housing 2 to ensure the sealing inside the lower housing 2. A buzzer through hole 29 is provided on the lower housing 2, and the buzzer through hole 29 is connected to the outside and will not be connected to the inside of the lower housing 2. The generating part of the buzzer 27 is connected to the external air, and the sound of the buzzer 27 is transmitted.

[0041] The fixing member 26 is a tubular structure, and a fixing member groove is provided inside the fixing member 26. The sealing ring 28 is located in the fixing member groove and is arranged radially. The diameter of the buzzer through hole 29 is 3.5 mm. In this embodiment, the buzzer 27 is electrically connected to the main control board 10. When the key 13 is triggered during the key operation, the main control board 10 receives the trigger signal, and the main control board 10 controls the buzzer 27 to emit a short sound. If the key 13 is not triggered, the buzzer will not sound. The buzzer 27 will emit a short sound to prompt the operator that this key is triggered.

[0042] The upper cover plate 1 is installed with corresponding buttons according to the button layout (two-column, four-column and coal mining machine). The upper cover plate layout can also be redesigned according to different layout requirements and patterns, and different buttons can be installed in different positions. The operation keyboard supports the installation of up to 32 independent buttons and 64 matrix buttons.

[0043] like Fig.12 and Fig.13 As shown, the utility model adopts the same structural design and the same circuit board in actual use. According to the different key layouts, number of keys and screen printing patterns of the upper cover plate 1, it can also be divided into a four-column bracket operation keyboard and a coal mining machine operation keyboard.
