[0002] Refer to Figure 1 As shown, generally, there is no protection for the USB interface on the machine port. During long-term use, dust often falls into the open USB interface and enters the inside of the USB interface, thus affecting the performance of the internal main board. At the same time, the USB interface is located on one side of the front plastic panel of the machine device. Even if a cap is manually set for protection of the USB interface, the stability of its protective end is poor, and it is extremely easy to fall off and be lost. Utility Model Content

[0003] In order to improve the problems of preventing dust from entering the USB interface and the frequent loss and dropping of the cap, this application provides a dust-proof and anti-dropping USB cap.

[0004] The dust-proof and anti-dropping USB cap provided by this application adopts the following technical solutions:

[0005] A dust-proof and anti-dropping USB cap includes a USB board, a control panel, and a USB cap. The USB cap passes through the control panel and the USB board and is buckled. Among them, the USB cap has a first end face and a second end face arranged oppositely. The first end face faces away from the USB board, and the second end face is close to the USB board. A boss is integrally formed on the first end face. A plug hole and a cylinder are arranged on the second end face. The plug hole passes through the control panel and the USB board and is buckled. The cylinder is rotatably arranged on the control panel. A notch for inlaying the USB cap is opened on the control panel, and the shape and specification of the notch are the same as those of the first end face / second end face.

[0006] By adopting the above technical solutions, the boss on the first end face facilitates manual opening of the USB cap. The USB cap is completely inlaid in the USB notch of the control panel. After the USB cap is completely inserted, the first end face completely covers the notch position, effectively blocking the notch to prevent water and dust from entering the notch. The cylindrical part on the second end face enables the USB cap to be blocked during use and rotated along the axis of the cylinder, facilitating it to be placed beside the notch, reducing the occurrence of the USB cap falling off and being lost.

[0007] Optionally, one end face of the plug hole is striated, and the other end face of the plug hole is smooth.

[0008] By adopting the above technical solutions, the plug hole is used for protecting the USB notch, and the striations on its side increase friction and enhance the fixing effect.

[0009] Optionally, a dustproof and waterproof layer is also fixed on the second end surface.

[0010] By adopting the above technical solution, the dustproof and waterproof layer on the second end surface prevents the USB cap from getting wet or adhering to dust when it is opened, and reduces the possibility of dust and water being brought in when the USB cap seals the notch.

[0011] Optionally, a guide hole for the cylinder to penetrate is provided on the control panel, and a through groove is also provided on the control panel, and the shape and specification of the through groove and the plug mouth are matched.

[0012] By adopting the above technical solution, the size and shape of the plug are the same as the through groove. When the USB cap is installed on the control panel, the plug seals the through groove to prevent dust and water from entering. The cylinder is located in the guide hole to facilitate the rotation of the USB cap.

[0013] Optionally, a PCB LCD screen is also installed on the control panel, and the PCB LCD screen and the control panel are snap-fitted together. A front plastic panel is also installed on the end of the PCB LCD screen facing away from the control panel, and the control panel and the front plastic panel are snap-fitted together.

[0014] By adopting the above technical solution, the PCB LCD screen is installed on the control panel, and the four sides of the control panel are buckled on the front plastic panel to improve the stability of the overall structural assembly.

[0015] Optionally, a plurality of positioning grooves are provided on the control panel, and a positioning column and a positioning pin are installed on the side of the PCB LCD screen close to the control panel. The positioning column is snapped into the positioning groove and fastened by a nut, and the positioning pin is tightly fitted with the positioning hole provided on the control panel.

[0016] By adopting the above technical solution, when the PCB LCD screen and the control panel are assembled, the positioning is guided by the positioning column and the positioning pin, making the installation more convenient. The positioning pin is clamped in the positioning hole to fix the bottom of the PCB LCD screen. Finally, the positioning column is locked in the positioning groove to ensure that the PCB LCD screen is firmly installed.

[0017] Optionally, a limiting frame is integrally formed on one side of the USB board close to the control panel; the USB cap is buckled on the USB board, and the inner wall of the limiting frame is in contact with the outer wall of the plug port.

[0018] By adopting the above technical solution, the limiting frame and the plug opening are tightly assembled against each other, so that the USB cap can be installed stably and the occurrence of deviation of the USB cap after installation is reduced.

[0019] Optionally, a protrusion is arranged on the end of the cylinder, and the protrusions are symmetrically arranged along the axis of the cylinder, and a gap is formed between two protrusions.

[0020] By adopting the above technical solution, when the end of the cylinder penetrates the guiding hole on the control panel, the gap decreases and the two protrusions approach each other; when the end of the cylinder passes through the guiding hole, the gap between the protrusions resumes to the initial spacing, enabling the cylinder to be hung within the guide and preventing the USB cap from falling off.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When the USB cap is fully embedded in the notch on the control panel, the first end face / second end face completely seals the notch, and the plug port seals the through groove, preventing dust and moisture from entering, strengthening the protection of the USB interface. The outer part of the plug port has stripes to increase friction and enhance the fixing effect;

[0023] 2. For the cylindrical part on the USB cap, during use, after opening the USB cap, it is rotated and placed beside the notch at an angle to prevent the USB cap from falling off or being lost;

[0024] 3. The position of the boss on the first end face facilitates manual opening of the USB cap;

[0025] 4. The boss on the first end face, the plug port and the cylinder on the second end face, when the USB cap is buckled on the USB interface, enhance the overall mechanical aesthetics. Description of the Drawings
