[0034] The utility model is further described in conjunction with the following embodiments.

[0035] Example 1.

[0036] like Figure 1-2 As shown, a card ejection mechanism of a card-insertion type card reader comprises a card slot 1, a locking mechanism 2 is arranged beside the card slot 1, a storage card 3 is inserted into the card slot 1, slideways 4 are arranged on both sides of the card slot 1, and an ejection mechanism 5 is installed at the bottom of the card slot 1, and the ejection mechanism 5 is installed in cooperation with the locking mechanism 2.

[0037] When in use, the storage card 3 is inserted into the slide 4 of the card slot 1 and pushed downward. After the storage card 3 is inserted, the pop-up mechanism 5 will be compressed, and the locking mechanism 2 will be controlled to lock the position of the pop-up mechanism 5 and the storage card 3. When performing the pop-up operation, it is only necessary to unlock the locking mechanism 2 and release the pop-up mechanism 5 to eject the storage card 3.

[0038] The pop-up mechanism 5 includes a moving block 6, on the top of which telescopic protrusions 7 are evenly installed. The telescopic protrusions 7 pass through the bottom of the card slot 1. A limiting groove 8 is provided on one side of the moving block 6. A telescopic spring 16 corresponding to the telescopic protrusion 7 is provided at the bottom of the moving block 6, and a fixing plate 9 is connected to the bottom end of the telescopic spring 16.

[0039] When the telescopic protrusion 7 in the ejection mechanism 5 is inserted into the storage card 3 in the card slot 1 and compressed, the moving block 6 can be compressed downward, so that the telescopic spring 16 installed below the moving block 6 is also compressed, thereby realizing the installation and ejection of the storage card 3.

[0040] The locking mechanism 2 includes a slide groove 10 , which is arranged on one side of the card slot 1 . An extended sliding bar 11 is installed inside the slide groove 10 . A moving head 12 is installed on the top of the extended sliding bar 11 . A positioning pin 13 is installed on the bottom end of the extended sliding bar 11 .

[0041] When the locking mechanism 2 is in use, the moving head 12 is controlled to move in the slide groove 10, and the extended sliding bar 11 installed below the moving head 12 is displaced laterally in the slide groove 10. The positioning pin 13 installed at the bottom of the extended sliding bar 11 is used to insert and limit the limit groove 8 opened on the moving block 6 to prevent the pop-up mechanism 5 from ejecting the storage card 3.

[0042] The positioning pin 13 cooperates with the limiting groove 8 provided on the moving block 6 , and the positioning pin 13 is inserted into the limiting groove 8 laterally.

[0043] A limit plate 14 is installed near the end of the moving head 12 of the extended sliding bar 11. The limit plate 14 passes through the slide 4 in the card slot 1 and extends into the card slot 1. After locking, the limit plate 14 will limit the top of the storage card 3, and form two sets of limit locking methods with the positioning pin 13 to increase the locking stability.

[0044] The telescopic protrusions 7 are all provided with a rubber buffer layer 15 , and the rubber buffer layer 15 provided on the telescopic protrusions 7 can prevent the bottom of the storage card 3 from being damaged by a hard collision when the storage card 3 is inserted.

[0045] During the production process, the storage card 3 entering the card slot 1 of the card reader is locked and ejected through the locking mechanism and the ejection mechanism 5 arranged on the card slot 1. When the storage card 3 is inserted, the telescopic protrusion in the ejection mechanism 5 can be compressed, so that the telescopic spring 16 under the moving block 6 is compressed to achieve the ejection effect. At the same time, the extended sliding bar 11 that can move laterally in the locking mechanism 2 on the side can lock and limit the limiting groove 8 opened on the moving block 6 through the positioning pin 13. The limiting plug plate 14 arranged on the top of the extended sliding bar 11 can limit the top position of the storage card 3. The storage card 3 can be quickly ejected by sliding the locking mechanism 2 housing, thereby improving the safety of installing and ejecting the storage card 3 and increasing the efficiency of using the card reader.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
