Technical Field

[0001] The utility model relates to the technical field of mobile phone card holders, in particular to a dual-slot mobile phone card holder. Background Technique

[0002] A mobile phone SIM card holder is a device used to fix and protect the SIM card. It can help the SIM card be fixed in the mobile phone and not easily fall off, and can prevent the SIM card from being damaged or lost. The main uses of the SIM card holder include fixing the SIM card, protecting the SIM card, and facilitating replacement. Generally speaking, the mobile phone SIM card holder is a mobile phone accessory designed to better protect and use the SIM card. For the existing mobile phone SIM card holders, when installing the SIM card, due to the small size of the SIM card, it is easy to fall off during installation, resulting in chip contamination or loss of the SIM card. When the SIM card needs to be taken out, the common method is to flip the card holder and shake it forcefully to pour out the SIM card, which is easy to fall and cause damage to the SIM card. To solve the above problems, a dual-slot mobile phone card holder is needed.

[0003] When operating an existing dual-slot mobile phone card holder, there are problems that it cannot prevent falling off and cannot automatically pop out. Therefore, a dual-slot mobile phone card holder is urgently needed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a dual-slot mobile phone card holder to solve the problems that the existing dual-slot mobile phone card holder cannot prevent falling off and cannot automatically pop out when in use.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A dual-slot mobile phone card holder, including a card holder plate, a thimble hole is opened on the side wall of the card holder plate, and a slot is opened on the inner wall of the card holder plate.

[0006] An anti-falling-off mechanism is installed on the inner wall of the card holder plate.

[0007] A return mechanism is installed at the bottom of the card holder plate.

[0008] Preferably, the anti-falling-off mechanism includes a slide bar, a return spring and a limiting plate. The slide bar is installed on the inner wall of the card holder plate, the return spring is installed on the outer wall of the slide bar, and the limiting plate is installed on the side wall of the return spring.

[0009] Preferably, the slide bars are symmetrically arranged with the central axis of the card holder plate as the center, and the limiting plate and the slide bar form a telescopic structure through the return spring.

[0010] Preferably, the upper surface of the limiting plate is provided with concave-convex stripes, and both sides of the limiting plate are provided with protrusions.

[0011] Preferably, the resilient mechanism includes a limit sleeve, a top piece, a limit spring and a limit rod. The limit sleeve is installed at the bottom of the card holder plate. The top piece is installed on the inner wall of the limit sleeve. The limit spring is installed at the bottom of the top piece. The limit rod is installed on the inner wall of the limit spring.

[0012] Preferably, the limit sleeve and the top piece are snap-connected. The top piece and the limit rod form a telescopic structure through the limit spring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the anti-detachment mechanism provided in the present utility model, the slide rods are symmetrically arranged around the central axis of the card holder plate. The limit plate and the slide rods form a telescopic structure through the return spring. When using the device, since there is no fixing component when installing the SIM card, the SIM card is likely to slide out of the card holder plate, resulting in dropping or loss. However, with the setting of the limit plate, during use, slide the limit plate along the slide rod to one side, then install the SIM card in the card slot of the card holder plate, and then release the limit plate. The limit plate slides back under the elastic force of the return spring, and the elastic forces of the return springs on both sides of the limit plate are the same, so that the limit plate always remains in the middle position of the card holder plate when not under force. At this time, the protruding parts on both sides of the limit plate squeeze and fix the SIM card, preventing the SIM card from detaching and increasing the stability of the device.

[0015] 2. Through the resilient mechanism provided in the present utility model, the limit sleeve and the top piece are snap-connected. The top piece and the limit rod form a telescopic structure through the limit spring. When using the device, when the SIM card needs to be taken out, the usual method is to flip the card holder plate and shake it forcefully to pour out the SIM card, which is likely to slide and be lost. However, the top piece jacks up the SIM card under the elastic force of the limit spring. At this time, when the limit plate is slid away, the limit plate releases the pressure fixation on the SIM card, and the SIM card is jacked up by the top piece and automatically pops out, facilitating the taking out of the SIM card and increasing the convenience of the device.

Due to the setting of the limit plate 403, when in use, slide the limit plate 403 along the slide bar 401 to one side, then install the SIM card in the card slot of the card tray plate 1, and then release the limit plate 403. The limit plate 403 slides back by the elastic force of the return spring 402, and the elastic forces of the return springs 402 on both sides of the limit plate 403 are the same, so that the limit plate 403 always remains in the middle position of the card tray plate 1 in the non-loaded state. At this time, the protruding parts on both sides of the limit plate 403 squeeze and fix the SIM card to prevent the SIM card from falling off and increase the stability of the device. Then, when it is necessary to take out the SIM card, the usual method is to flip the card tray plate 1 and shake it forcefully to pour out the SIM card, which is easy to slip and be lost. However, the top piece 502 pushes up the SIM card by the elastic force of the limit spring 503. At this time, when the limit plate 403 is slid away, the limit plate 403 releases the pressure fixation on the SIM card, and the SIM card is pushed up by the top piece 502 and automatically pops out, facilitating the taking out of the SIM card and increasing the convenience of the device. In this way, the use process of the device is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
