Description

Technical Field

[0001] The utility model relates to a computer host structure, in particular to a case interface plug-in type closing mechanism. Background Art

[0002] A desktop computer usually includes a chassis, monitor, keyboard, mouse and other accessories. The chassis is a box that holds core components such as the processor, graphics card, hard disk, and motherboard.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] refer to Figures 1 to 5A chassis interface plug-in closure mechanism includes a chassis shell 1 and a USB interface 7, wherein the USB interface 7 is located in a slot 2 on the chassis shell 1; there is at least one USB interface 7 on the chassis shell 1, and the USB interface 7 is used to plug in USB plugs of accessories such as a mouse, keyboard, U disk, and mobile hard disk.

[0031] The USB interface 7 and the USB plug are both USB protocol standard interfaces.

[0032] The above-mentioned plug-in type sealing mechanism further comprises a sliding sealing plate 3, an elastic member 5 and an inner sealing sheet 6;

[0033] The sliding closing plate 3 is movably disposed in the sliding groove 4 of the chassis shell 1 and can be closed and opened to close or open the slot 2; it serves as the outermost protective barrier of the slot 2 and plays a waterproof and dustproof role.

[0034] The sliding closing plate 3 is provided with a guide fin 31 , and the guide fin 31 is provided with a guide slope; the guide fin 31 is in a sheet shape and is used for guiding.

[0035] The elastic member 5 is located in the slide groove 4 and connects the slide groove 4 and the sliding closing plate 3; the elastic member 5 is used to apply elastic force to the sliding closing plate 3, so that the sliding closing plate 3 maintains a normally closed state.

[0036] The inner sealing sheet 6 is connected to the slot 2 and is located between the sliding closing plate 3 and the USB interface 7; the inner sealing sheet 6 serves as the innermost protective barrier of the slot 2 and plays a role in waterproofing and dustproofing.

[0037] The inner sealing sheet 6 includes a first sealing portion 62 and a second sealing portion 63 , which cooperate with each other and are both used for sealing.

[0038] The slide groove 4 is extended along the plane where the chassis shell 1 is located, that is, the slide groove 4 is completely in the side wall of the chassis shell 1, and the slide groove 4 is connected with the slot 2; the width of the slide groove 4 is greater than the thickness of the sliding closing plate 3, thereby ensuring that the sliding closing plate 3 can slide back and forth in the slide groove 4.

[0039] The sliding closing plate 3 is in the shape of a flat plate, and the guide fins 31 are specifically located on the side of the sliding closing plate 3 away from the USB interface 7, that is, the guide fins 31 are arranged toward the outside of the chassis shell 1, so that the USB plug can touch the guide fins 31 first.

[0040] The guide slope is arranged in an inclined shape relative to the sliding closing plate 3, so that under the action of the slope, a component force along the slide groove 4 can be generated on the sliding closing plate 3 during the insertion of the USB connector, thereby driving the sliding closing plate 3 to slide along the slide groove 4; and an arc portion 34 is provided at the connection between the guide slope and the end of the sliding closing plate 3 away from the elastic member 5, and the arc portion 34 is used for guiding and transitioning, reducing friction, and avoiding damage to the USB connector.

[0041] A first slippery layer 32 is provided on the guide slope; a second slippery layer 33 is provided on the side of the sliding closing plate 3. The first slippery layer 32 and the second slippery layer 33 are both made of slippery materials, such as Teflon. The first slippery layer 32 and the second slippery layer 33 are used to help slip and reduce friction.

[0042] The slide slot 4 also includes a clearance groove 41, which is connected to the slide slot 4 and the slot 2, and corresponds to the position of the guide fin 31. The clearance groove 41 is used to make way for the movement of the guide fin 31 to avoid structural interference.

[0043] refer to Figure 3 The inner sealing sheet 6 includes a sheet body 61, which is in sheet shape and connected to the outline of the slot 2 at its edge. The inner sealing sheet 6 is made of a flexible material, which can be rubber or silicone.

[0044] The first sealing portion 62 and the second sealing portion 63 are arranged opposite to each other and are both connected to the middle of the sheet body 61; the first sealing portion 62 and the second sealing portion 63 are both in a U-shape, and are used to seal the USB interface 7 to prevent water and dust.

[0045] A first serration portion 64 is provided on the side of the first sealing portion 62 close to the second sealing portion 63, and a second serration portion 65 is provided on the side of the second sealing portion 63 close to the first sealing portion 62; the serration structures of the first serration portion 64 and the second serration portion 65 cooperate with each other, and the serrations of the first serration portion 64 can form a continuous cooperation with the serrations of the second serration portion 65, thereby realizing the cooperation between the first sealing portion 62 and the second sealing portion 63 to ensure the sealing effect.

[0046] The specific usage / working principle of the utility model is:

[0047] If you need to insert the USB plug of an accessory such as a mouse, keyboard, U disk, or mobile hard disk into the USB interface 7 on the chassis housing 1, hold the USB plug of the accessory with one hand to insert it, and the USB plug contacts the guide fins 31 on the sliding closing plate 3 of the closing mechanism. Under the separation effect of the guide inclined surface on the guide fins 31, the sliding closing plate 3 and the chassis housing 1 move relative to each other, and the sliding closing plate 3 slides along the slide groove 4, overcomes the elastic force of the elastic member 5, and gives way. That is, during the insertion process of the USB plug, the sliding closing plate 3 can give way, which is convenient for the insertion operation and can greatly improve the user experience.

[0048] When the USB plug moves away the sliding closing plate 3 and is inserted into the slot 2, the USB plug is in contact with the inner sealing sheet 6. Since the inner sealing sheet 6 is made of rubber and is soft, the end of the USB plug can push open the first sealing portion 62 and the second sealing portion 63 relative to the sheet body 61 during the movement, and then be inserted into the USB interface 7, thereby finally achieving plug-in cooperation with the USB interface 7.

[0049] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
