[0002] With the development of information technology, computer systems are increasingly used in the coal mining industry. From production scheduling to safety management, computers have become indispensable tools. However, the coal mining environment is unique. The air often contains large amounts of dust, coal particles, and other debris. These pollutants can easily infiltrate computer keyboards and other peripherals, leading to increased equipment failure rates, rising maintenance costs, and affecting work efficiency.

[0003] Traditional keyboards are exposed to the elements during use, making them ineffective against external contaminants. This is especially true in harsh environments like coal mines. Dust and coal dust accumulate inside the keyboard after prolonged use, affecting key feel and responsiveness and potentially causing short circuits. To address this issue, keyboards with protective covers or sealed structures have emerged on the market. However, these designs often come with drawbacks such as inconvenience and inability to completely prevent the ingress of contaminants. Utility Model Content

DETAILED DESCRIPTION

[0040] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] The utility model relates to a keyboard for a coal mine management system which is easy to clean. Figures 1 to 7 Shown, including:

[0042] Base 1, the basic part of the entire device, is independently fixed and has a storage cavity;

[0043] The support frame 2 is provided at the top of the base 1. A notch is provided on one side of the support frame 2 to allow the keyboard to enter and exit. An adjustment slot is provided at the connection between the support frame 2 and the base 1 at one end of the notch to adjust the support angle of the keyboard.

[0044] The driving mechanism 3 is provided on the support frame 2, and the driving mechanism 3 provides power for the keyboard to enter and exit the slot of the support frame 2;

[0045] The moving member 4 is provided on the driving mechanism 3 and is provided with a positioning groove for positioning the keyboard to ensure that the keyboard remains stable during storage and use. The moving member 4 is slidably connected to the base 1;

[0046] Screw 5 is set in the threaded inner hole of the moving part 4 to lock the position of the keyboard and the moving part 4. When the keyboard is placed, tightening the screw 5 can firmly fix the keyboard on the moving part 4 to prevent it from accidentally sliding out;

[0047] A sealing mechanism 6 is provided on the top of the support frame 2. The sealing mechanism 6 cooperates with the base 1 to seal the keyboard inside the support frame 2. When the keyboard is not in use, it can be sealed inside the support frame 2, helping to prevent external contaminants from entering while keeping the keyboard clean.

[0048] The working principle of this device is as follows:

[0049] When the keyboard needs to be used, the user can control the driving mechanism 3, which will push the moving member 4 to slide outward until the keyboard is completely exposed from the notch of the support frame 2;

[0050] After use, the driving mechanism 3 is started again to retract the moving part 4 with the keyboard into the support frame 2. At this time, the sealing mechanism 6 and the base 1 form a sealed space to protect the keyboard from contamination.

[0051] When the keyboard is not in use, the sealing mechanism 6 is always kept closed to ensure that the keyboard is always in a clean and tidy state;

[0052] Through the cooperation of the sealing mechanism 6 and the base 1, a closed environment can be formed when the keyboard is not in use, effectively preventing external pollutants such as dust and coal particles from entering the support frame 2, keeping the keyboard always in a clean and tidy state, which is crucial for computer systems working in special environments such as coal mines, reducing the failure rate caused by dust and debris. The user only needs to simply control the drive mechanism 3 to realize the automatic entry and exit of the keyboard, without manually pulling out or pushing the keyboard in, simplifying the operation process and improving work efficiency. At the same time, the positioning groove design on the moving part 4 ensures the stability of the keyboard during storage and use, avoiding the inconvenience caused by accidental sliding. The notch design at the top of the support frame 2 and the application of the adjustment slot not only allow the keyboard to enter and exit smoothly, but also support the adjustment of the keyboard support angle according to user needs to adapt to different work scenarios and personal preferences, thereby making better use of limited space resources.

[0053] The traditional driving method can be realized by using existing technologies such as simple motor drive or manual push and pull, but these existing technologies can only realize simple linear movement or switch action functions. Since the present device requires a driving mechanism that can not only accurately control the keyboard in and out, but also maintain the stability of the keyboard during movement, but also has a fast response and easy maintenance. In order to solve the above problems, the present device designs a better driving mechanism 3, such as Figures 1 to 7 Shown, including:

[0054] Two mounting members 31 are symmetrically arranged at both ends of the moving member 4. The two mounting members 31 are slidably connected to the inner walls of the support frame 2 at the corresponding ends to ensure that the moving member 4 can move smoothly along a straight path. The moving member 4 is rotatably mounted around the inner holes of the two mounting members 31, allowing the keyboard to be easily adjusted in angle after it is fully moved out.

[0055] Two transmission shafts 32 are rotatably disposed in the connection holes of the two mounting members 31, and the rotation axes of the two transmission shafts 32 are parallel to the movement tracks of the mounting members 31;

[0056] Two threaded columns 33 are coaxially arranged on the two transmission shafts 32, and the threaded columns 33 are installed in conjunction with the threaded grooves at the corresponding ends of the support frame 2. As the transmission shaft 32 rotates, the threaded columns 33 will move linearly in the threaded grooves, thereby pushing or pulling the moving member 4;

[0057] The servo motor 34 is mounted on a mounting member 31, and the output end of the servo motor 34 is connected to the transmission shaft 32. The servo motor 34 is the power source of the entire drive system and can generate precise rotation according to the control instructions.

[0058] The transmission mechanism 35 is provided on the two transmission shafts 32 and is used for synchronous rotation of the two transmission shafts 32;

[0059] The control mechanism 36 is provided on the sealing mechanism 6 and is used to control the direction of the servo motor 34. The control mechanism receives an operation command from the user to determine whether the servo motor 34 rotates forward or reverse, thereby controlling the entry and exit movement of the keyboard;

[0060] The working principle of the driving mechanism 3 of this device is as follows:

[0061] When the user needs to use the keyboard, the control system activates the servo motor 34, which drives the transmission shaft 32 on one side to rotate. The transmission mechanism 35 causes the transmission shaft 32 on the other side to rotate synchronously. The rotating transmission shaft 32 drives the threaded column 33 to move outward along the threaded groove on the support frame 2, thereby pushing the moving member 4 together with the keyboard out of the notch of the support frame 2;

[0062] After use, the servo motor 34 is started again, but this time it rotates in the opposite direction, which will cause the threaded column 33 to move inward, pulling the moving member 4 and the keyboard back into the support frame 2. At this time, the sealing mechanism 6 is closed, forming a sealed space to protect the keyboard from external contamination;

[0063] The control mechanism 36 is located on the sealing mechanism 6. It can control the direction of the servo motor 34 according to user needs or preset logic to ensure that the keyboard entry and exit process is automated, safe and reliable.

[0064] As a preferred solution, Figures 3 to 7 Shown, including:

[0065] Two pulleys 35a are coaxially arranged on the two transmission shafts 32;

[0066] The transmission belt 35b is rolled on two pulleys 35a. The pulleys 35a serve as support points for the transmission belt 35b and transmit the power of the servo motor 34 to the other transmission shaft 32, driving the two transmission shafts 32 to rotate synchronously. Each pulley 35a is designed with precise teeth or grooves to ensure that the transmission belt 35b can fit tightly and effectively transmit power.

[0067] The transmission mechanism 35 of the present invention not only realizes the synchronous rotation of the two transmission shafts 32, but also ensures the simplicity and reliability of operation. It is particularly suitable for keyboard management of computer systems in special environments such as coal mines. The selection and installation method of the transmission belt 35b further improves the stability and durability of the system, reduces maintenance costs and enhances user experience.

[0068] As a preferred solution, Figures 1 to 6 As shown, the control mechanism 36 includes:

[0069] The switch system 36a is provided on the sealing mechanism 6. The switch system 36a is provided with a keyboard storage button and a keyboard deployment button, including a keyboard storage button and a keyboard deployment button, providing an intuitive and easy-to-operate human-machine interface for directly controlling the direction of the servo motor 34;

[0070] The battery 36b is disposed inside the storage cavity of the base 1. The battery 36b provides a stable and continuous power supply to the servo motor 34. The battery 36b should be an explosion-proof or certified safety battery.

[0071] When the user needs to use the keyboard, he only needs to press the keyboard expansion button. After receiving the signal, the control system activates the servo motor 34 to rotate forward. After use, the user presses the keyboard storage button again, and the control system sends a reverse instruction to the servo motor 34. The control mechanism 36 of the utility model not only realizes precise steering control of the servo motor 34, but also provides a simple operation interface and reliable power supply. It is particularly suitable for keyboard management of computer systems in special environments such as coal mines. The design of the switch system 36a takes into account the user experience, and the selection of the battery 36b improves the stability and safety of the system.

[0072] The traditional sealing mechanism can be realized by using existing technologies such as simple cover or flip cover, but these existing technologies can only realize simple covering or opening functions. Since the present device requires a sealing mechanism that can not only ensure the effective sealing inside the support frame but also provide a convenient cleaning tool storage solution, in order to solve the above problems, the present device designs a better sealing mechanism 6, such as Figures 1 to 6 As shown, the sealing mechanism 6 particularly includes:

[0073] The sealing cover 61 is provided on the support frame 2 and is provided with a storage slot for storing cleaning brushes and wiping cloths. The switch system 36a is provided on the sealing cover 61 to provide an intuitive operation interface for the user;

[0074] The rotating cover 62 is disposed at the storage slot of the sealing cover 61, and the rotating cover 62 has an interference fit with the storage slot. This design ensures that the rotating cover 62 can tightly close the storage slot to prevent dust or particles from entering. At the same time, the rotating cover 62 can be easily rotated to open, making it convenient for users to take out cleaning tools;

[0075] An extension piece 63 is provided on the rotating cover 62 to facilitate manual operation of the rotating cover 62 by the user;

[0076] The sealing mechanism 6 of the present invention not only achieves effective sealing of the interior of the support frame 2, but also provides a convenient storage solution for cleaning tools. It is particularly suitable for keyboard management of computer systems in special environments such as coal mines. The design of the sealing cover 61 takes into account the needs of dust prevention and cleaning, while the rotating cover 62 and its extension 63 improve the usability and aesthetics of the system.

[0077] As a preferred solution, Figure 2 As shown, the bottom end of the moving member 4 is provided with a mounting slot, and an adjusting leg 41 is rotatably provided in the mounting slot, allowing the user to adjust the height and tilt angle of the keyboard according to actual needs;

[0078] The design of the adjustment leg 41 takes the user's personalized needs into consideration, which not only enables convenient adjustment of the keyboard height and tilt angle, but also improves the stability and adaptability of the system.

[0079] As a preferred solution, Figure 4 As shown, a sealing gasket 42 is provided at the top of the moving member 4 for sealing the notch of the support member when the keyboard is in the storage state, thereby preventing external contaminants from entering the support frame 2 and keeping the keyboard clean;

[0080] The sealing gasket 42 not only achieves effective sealing of the notch of the support frame 2, but also enhances the reliability of the system and the convenience of the user.

[0081] The utility model provides a keyboard for a coal mine management system that is easy to clean. The installation method, connection method or setting method thereof are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
