[0033] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. Each technical feature in the creation of the present utility model can be combined interactively on the premise of not conflicting with each other.

[0034] Referring to Figures 1 to 4 , a card ejection device includes a housing 1, a card reader 2 is installed in the housing 1, the card reader 2 is provided with a card slot 21 and a card ejection button 22, and by pressing the card ejection button 22, the card in the card slot 21 can be ejected;

[0035] A housing bayonet 11 is opened on the housing 1, and the card slot 21 is aligned with the housing bayonet 11;

[0036] A slot 12 is provided on the housing 1 and adjacent to the card reader 2, a first button 3 slides in the slot 12, and the first button 3 is connected to the inner side of the housing 1 through an elastic member 4;

[0037] When the elastic member 4 is stretched, the first button 3 presses the card ejection button 22, and the card in the card slot 21 is ejected;

[0038] When the elastic member 4 is reset, the first button 3 moves away from the card ejection button 22.

[0039] When the user needs to eject the card, the first button 3 can be pulled from the outside of the housing 1 to drive the first button 3 to slide in the slot 12. Driven by the first button 3, when the elastic member 4 is stretched, the first button presses the card ejection button 22, so that the card is ejected from the card slot 21; when the first button 3 is released, the elastic member 4 is reset, and the first button 3 no longer presses the card ejection button 22; It can be seen that the card ejection operation in this device is achieved through the mutual cooperation of the first button 3, the slot 12 and the elastic member 4, with a simple structure, low manufacturing cost and convenient operation.

[0040] This device can be applied to devices that provide various services by inserting a card and reading the information on the card, such as ATM machines, POS machines, self-service ticket vending machines, and self-service recharge machines.

[0041] Referring to Figures 5 to 6, in one embodiment, the first button 3 includes a tongue 31, a first connecting member 32 fixedly connected to the tongue 31 vertically, and a second connecting member 33 connected to the first connecting member 32. The tongue 31 extends out of the housing 1 along the slot 12, and the first connecting member 32 is disposed inside the housing 1; one end of the elastic member 4 is connected to the second connecting member 33, and the other end of the elastic member 4 is connected to the inner side of the housing 1;

[0042] When the user presses the tongue 31, the elastic member 4 is stretched, the second connecting member 33 presses the card ejection button 22, and the card in the card slot 21 ejects;

[0043] When the user releases the tongue 31, when the elastic member 4 resets, the second connecting member 33 moves away from the card ejection button 22.

[0044] Specifically, the width of the end of the tongue 31 away from the first connecting member 32 is greater than the width of the slot 12, which can play a role in limiting and ensure that the tongue 31 is always outside the housing 1.

[0045] Specifically, a slot 321 is provided on the first connecting member 32, and a plug 331 is provided at one end of the second connecting member 33. The plug 331 is located in the slot 321. The arrangement of the plug 331 and the slot 321 facilitates the handling and assembly of the device, and the insertion direction of the second connecting member 33 and the first connecting member 32 is perpendicular to the axis of the elastic member 4; when the elastic member 4 expands and contracts, it will not affect the connection relationship between the plug 331 and the slot 321, ensuring that the relative positions of the first connecting member 32 and the second connecting member 33 remain fixed.

[0046] More specifically, a pressing block 332 is further provided at one end of the second connecting member 33, and the pressing block 332 abuts against the tongue 31. The pressing block 332 and the slot 321 cooperate with each other to strengthen the connection stability between the second connecting member 33 and the first connecting member 32, and prevent the second connecting member 33 from falling off the first connecting member 32 when the elastic member 4 expands and contracts.

[0047] Specifically, a first limiting flap 51 and a second limiting flap 52 are respectively fixedly connected to two sides adjacent to the slot 12 inside the housing 1; two sides of the first connecting member 32 are slidably abutted against the first limiting flap 51 and the second limiting flap 52 respectively; the second connecting member 33 extends from the gap between the first limiting flap 51 and the second limiting flap 52 towards the card ejection button 22;

[0048] When the elastic member 4 is stretched / reset, it drives the first connecting member 32 to slide on the first limiting block 51 and the second limiting block 52. The first connecting member 32 is used to fix the position of the first button 3 on the first limiting block 51. If the first limiting block 51 and the second limiting block 52 are not provided, the user may need to pinch the tongue 31 with the thumb and index finger and slowly move the first connecting member 32 along the direction of the slot 12. Otherwise, the tail of the first connecting member 32 may be lifted up in the housing 1, and the elastic member 4 may be separated from the second connecting member 33, affecting the use of the device.

[0049] More specifically, the horizontal cross-section of the second limiting blocking piece 52 is shaped like a “U”, and the horizontal cross-sections of the first limiting blocking piece 51 and the second limiting blocking piece 52 are shaped like a “Z”.

[0050] More specifically, the connection point between the elastic member 4 and the second connecting member 33 is located between the first limiting block 51 and the second limiting block 52. The short distance between the elastic member 4 and the insert block 331 and the pressure block 332 can reduce the possibility of the second connecting member 33 being separated from the first connecting member 32.

[0051] In any of the above embodiments, the elastic member 4 is a hook spring, and the second connecting member 33 is provided with a spring hook groove 333, through which one end of the hook spring passes to connect with the second connecting member 33, thereby further reducing the possibility of the elastic member 4 and the second connecting member 33 being disconnected.

[0052] Specifically, the second connecting member 33 includes a connecting arm 334 connected to the first connecting member 32, and a pressing member 335 provided at the end of the connecting arm 334 away from the first connecting member 32, and the pressing member 335 is located directly above the card ejection button 22; when the elastic member 4 is stretched, the pressing member 335 presses the card ejection button 22, and the card in the card reading port 21 is ejected; when the elastic member 4 is reset, the pressing member 335 is away from the card ejection button 22.

[0053] In one embodiment, the slot 12 is provided above the housing latch 11 .

[0054] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
