Embodiment 1

[0019] Example 1 as figure 1 , figure 2 , image 3 with Figure 4 As shown, the protection device for the external port of electrical equipment of the present invention includes a panel 1 and a cover plate 2, the panel 1 has at least one hole 11 for the external port, grooves 12 are respectively opened on both sides of the panel 1, and the grooves 12, the upper section is widened inwardly, the back of the panel 1 is provided with a ridge-shaped flange 13 outside the groove 12, the cover plate 2 is located on the front of the panel 1, and the two sides of the back of the cover plate 2 are respectively provided with There is a bracket 21, the end of the bracket 21 is provided with a support foot 22, and the support foot 22 is folded back toward the back of the cover plate 2, so that the support foot 22 can be bent inwardly, and the outer surface of the end of the support foot 22 is A bulge 23 is provided, and the cross-sectional size of the bulge 23 is smaller than the inne...

Embodiment 2

[0027] Example 2 as figure 1 As shown, on the basis of Embodiment 1, the front of the panel 1 is provided with protruding guide rails 15 on the outside of the two grooves 12, and when the cover plate 2 slides along the front of the panel 1, its back is against The guide rail 15. This design makes the back of the cover plate only contact with the raised guide rail when sliding on the front of the panel, and does not rub against the front of the panel, so as to avoid wear on the front of the panel.

[0028] The invention solves the problems that the cover plate of the traditional protection device for the external port is easy to fall off, the sliding is not smooth, and the installation is inconvenient. The protection device has a firm structure, beautiful and novel appearance, the cover plate and the panel are closely connected without gaps, the two are naturally integrated in appearance, and can be easily moved with fingers, and the operation is smooth. There is no need to u...

Abstract

The invention discloses an electrical equipment external port protection device, which comprises a panel, wherein a hole of at least one external port is formed in the panel, grooves are formed in both sides of the panel, the upper section of each groove is widened toward the inner side, and the back surface of the panel is provided with ridged flanges on the outer sides of the grooves; a cover plate is arranged on the front surface of the panel, two sides of the back surface of the cover plate are each provided with a bracket, the tail end of each bracket is provided with a supporting foot, the outer sides surface of the tail end of each supporting foot is provided with a bump, the two brackets at the back surface of the cover plate and the supporting feet are inserted into the grooves at the widened sections of the panel grooves, the bump surface of each supporting foot is presses against the corresponding ridged flange at the back surface of the panel, the two brackets at the back surface of the cover plate slide along the grooves, the bumps of the supporting feet slide along the ridged flanges, the hole of the external port in the panel is exposed when the cover plate slides to the top ends of the grooves through the brackets and the supporting feet, and the cover plate covers the hole of the external port in the panel when sliding to the bottom ends of the panel grooves. The electrical equipment external port protection device is convenient in installation and firm in structure, is not prone to fall off, is flexible in switching on / off, is beautiful and novel in appearance, and effective protects electrical connection performance of the external port.

Description

technical field [0001] The invention relates to a protection device for an external port of electrical equipment. Background technique [0002] Generally, electrical equipment is equipped with various external ports, such as USB ports, flash memory card ports, network ports, etc., for connecting external devices to achieve electrical connections; exposed external ports are easy to accumulate dust or be corroded by harmful media, which affects the performance of electrical connections. Generally, the protective structures of the external ports mainly include a plug cover type, a rotating shaft cover plate type and a sliding cover plate type. The plug-type appearance is not beautiful, and the plug is easy to fall off and lose. The shaft cover type has a fragile shaft, and when the opening angle is too large or the force is improper, the shaft is likely to break or fall off. The sliding cover plate type has problems such as inflexible sliding, inconvenient finger movement, di...
