[0041] The present invention provides a clock-in device 100, which aims to solve the problem that the current clock-in device 100 can only perform the clock-in function and affects the electricity consumption of users.

[0042] The specific structure of the punch card device 100 of the present invention is described below:

[0043] Combined with reference Figure 1 and Figure 5 In one embodiment of the punching device 100 of the present invention, the punching device 100 includes a housing 10, a punching assembly 20, at least two sockets 30 and a conductive member 40;

[0044] An installation cavity is formed in the shell 10, and the shell 10 has a display window 121, and is provided with a through hole 111 and at least two sockets 122 connected to the installation cavity, and at least two of the sockets 122, the display window 121 and the through hole 111 are arranged at intervals; the punching assembly 20 is arranged in the installation cavity, and has a display screen 221 and a wireless module 23 arranged at intervals, the display screen 221 is arranged opposite to the display window 121, the wireless module 23 is electrically connected to the display screen 221, and is used to communicate with the mobile terminal to update the display screen on the display screen 221 in real time; at least two sockets 30 are arranged in the installation cavity, and each socket 30 is arranged opposite to one of the sockets 122; the conductive member 40 is electrically connected to the punching assembly 20 and at least two of the sockets 30, and is penetrated through the through hole 111, and is used to be electrically connected to an external power supply to power the punching assembly 20 and at least two of the sockets 30.

[0045] It can be understood that the punching device 100 of the present invention has a punching assembly 20 installed in the housing 10, the punching assembly 20 is electrically connected to the wireless module 23, and at least two sockets 30 and a conductive member 40 are also installed in the housing 10. The conductive member 40 is electrically connected to the punching assembly 20 and the at least two sockets 30, and is penetrated through the through hole 111 of the housing 10 for being electrically connected to an external power source to supply power to the punching assembly 20 and the at least two sockets 30; in this way, during use, the punching assembly 20 can be supplied with power through the conductive member 40. The clock-in device 100 is powered by the component 20 and at least two sockets 30. On the one hand, the tenant can scan the QR code on the display screen 221 on the clock-in component 20 through the display window 121 to clock in. At the same time, the QR code on the display screen 221 can be updated in real time under the control of the wireless module 23 to prevent the tenant from taking photos and clocking in remotely. On the other hand, each plug of the device to be charged can be inserted into a socket 122 and inserted into a socket 30 to power the device to be charged. That is, the clock-in device 100 can also function as a socket. Therefore, the technical solution of the present invention solves the problem that the current clock-in device 100 can only function as a clock-in, which affects the user's electricity consumption.

[0046] Specifically, two sockets 122 may be provided, in which case they can be adapted for use with two plugs; or, three sockets 122 may be provided, in which case they can be adapted for use with three plugs; or, the socket 122 may be provided with two sockets 122 adapted for use with two plugs and three plugs adapted for use with three plugs, that is, a total of five sockets 122 are provided; similarly, the number of sockets 30 and sockets 122 is consistent, that is, when two sockets 122 are provided, two sockets 30 are also provided, and so on, which will not be repeated here.

[0047] The socket 30 can be fixed to the punch assembly 20 by welding, plugging, snapping, etc., or can be fixed to the cavity wall of the installation cavity by welding, plugging, snapping, etc.; the punch assembly 20 can be fixed in the installation cavity of the shell 10 by screws, buckles, crimping, etc. to ensure the installation stability of the punch assembly 20.

[0048] It should be noted that the punching device 100 of the present invention can be directly plugged into an ordinary wall socket, in which case it can be used as a transfer socket; or, the punching device 100 can be installed on an ordinary wall in the same manner as an ordinary wall-mounted socket to be used as a wall-mounted socket.

[0049] In actual application, when the punching device 100 is used as a transfer socket, the socket 30 can be directly electrically connected to the punching component 20. At this time, when the conductive member 40 supplies power to the punching component 20, the socket 30 can be powered by the punching component 20; or, when the punching device 100 is used as a wall socket, the socket 30 can be electrically connected to the pre-buried wires on the wall using wires.

[0050] In one embodiment, in conjunction with reference to Figures 1 to 4 The following will take the case where the punching device 100 is used as a transfer socket as an example for explanation:

[0051] Combined with reference Figure 1 In one embodiment of the punching device 100 of the present invention, at least two of the sockets 30 are electrically connected to the punching assembly 20, so that the conductive member 40 is electrically connected to at least two of the sockets 30 through the punching assembly 20. In this way, when the conductive member 40 supplies power to the punching assembly 20, the socket 30 can be powered by the punching assembly 20, without the need to set up an additional circuit or battery to provide power to the socket 30, thereby improving the convenience of using the punching device 100.

[0052] Combined with reference Figure 1 and Figure 2 In one embodiment of the punch card device 100 of the present invention, the housing 10 has a front side and a back side that are arranged back to back, the front side has the display window 121 and is provided with the jack 122, and the back side has the through hole 111. By arranging both the display window 121 and the jack 122 on the front side of the housing 10, it is convenient for the user to scan the QR code on the display screen 221 through the display window 121, and it is also convenient for the user to insert the plug of the device to be powered into the corresponding jack 122; in addition, by arranging the through hole 111 on the back side of the housing 10, it is convenient for the conductive member 40 to pass through the through hole 111 on the back side and be electrically connected to the socket on the wall.

[0053] Combined with reference Figure 1 In one embodiment of the punching device 100 of the present invention, at least two through holes 111 are provided, and at least two of the through holes 111 are arranged at intervals. The conductive member 40 includes at least two pins, and at least two of the pins are electrically connected to the punching component 20. Each of the pins is inserted into one of the through holes 111 and protrudes from the back side, and is used to be plugged into a socket to supply power to the punching component 20.

[0054] With such a configuration, when installing the clock-in device 100, the clock-in component 20 can be powered by directly plugging the pin on the clock-in device 100 into the socket on the wall, so that the clock-in component 20 is in a pass state. At this time, the clock-in device 100 is in normal use, and the tenant can scan the QR code on the display screen 221 on the clock-in component 20 through the front display window 121 to clock in.

[0055] Combined with reference Figure 1 , Figure 3 and Figure 4 In one embodiment of the punching device 100 of the present invention, the back surface is further provided with a clearance hole 112 spaced apart from the through hole 111; the punching device 100 further includes a micro switch 50, which is disposed in the installation cavity and electrically connected to the punching assembly 20, and a contact 51 of the micro switch 50 is penetrated through the clearance hole 112 and protrudes from the back surface;

[0056] Among them, when the pin is inserted into the socket, the contact 51 abuts against the socket to trigger the micro switch 50, so that the punch assembly 20 is in a circuit state; when the pin is pulled out of the socket, the contact 51 disengages from the socket to reset the micro switch 50, so that the punch assembly 20 is in a circuit-breaking state.

[0057] With such a configuration, when the clocking-in device 100 is installed, the pin can be inserted into the socket to supply power to the clocking-in component 20. During this process, the contact 51 abuts against the socket to trigger the microswitch 50, so that the clocking-in component 20 is in a connected state. At this time, the clocking-in device 100 is in normal use, and the tenant can scan the QR code on the display screen 221 on the clocking-in component 20 through the front display window 121 to clock in; if the pin in the clocking-in device 100 is pulled out of the socket, during this process, the contact 51 is disengaged from the socket to reset the microswitch 50, so that the clocking-in component 20 is in an open circuit state. At the same time, the chip in the microswitch 50 sends a reset signal to the mobile terminal or the control module of the clocking-in device 100, so as to control the clocking-in component 20 to fail through the mobile terminal or the control module. At this time, the clocking-in device 100 cannot be used again. Therefore, the tenant cannot move the punching device 100 at will, so that the punching device 100 has an anti-plugging function, which can prevent the tenant from subletting or group renting.

[0058] The card punching device 100 of the present invention has the effect of single use only. During use, if the pin in the card punching device 100 is pulled out of the socket, the contact 51 will be separated from the socket to reset the micro switch 50. At this time, the reset signal can be sensed by the chip inside the micro switch 50, and the reset signal is sent to the mobile terminal or the control module on the card punching device 100, so as to control the card punching assembly 20 to fail through the mobile terminal or the control module. It should be noted that the control module on the card punching device 100 can be the circuit board 21 on the card punching assembly 20, or it can be a control module electrically connected to the circuit board 21 on the card punching assembly 20. The control module is connected to the chip in the micro switch 50 for communication to receive the signal transmitted by the chip in the micro switch 50.

[0059] The micro switch 50 is a common sensitive switch. For example, the micro switch 50 includes a trigger member and a contact piece, the trigger member has a trigger surface, a trigger point is arranged on the trigger surface, the contact piece has a fixed end and a free end arranged opposite to each other, the fixed end is connected to the trigger surface, so that the trigger point is located on the inner side of the contact piece, and the trigger point is arranged close to the fixed end, and the contact 51 is arranged at the free end; in this way, when the pin is inserted into the socket, the contact 51 will abut against the socket, so that the contact 51 slides along the clearance hole 112, and the contact piece can be driven to touch the trigger point in a lever manner, thereby triggering the micro switch 50; or, a trigger point is directly arranged on the trigger surface of the micro switch 50, when the pin is inserted into the socket, the contact 51 will abut against the socket, so that the contact 51 slides along the clearance hole 112, and the trigger point can be directly touched by pressing, thereby triggering the micro switch 50.

[0060] In actual application, the micro switch 50 can be set on the side of the punching component 20 facing away from the display window 121, and can be set at intervals with the pins, or can be set side by side with the punching component 20; similarly, the pins can be set on the side of the punching component 20 facing away from the display window 121, or can be set side by side with the punching component 20.

[0061] Furthermore, the micro switch 50 is disposed on the side of the punching assembly 20 facing away from the display window 121. With such a configuration, the micro switch 50 and the punching assembly 20 can be reasonably arranged in the thickness direction of the housing 10 to fully utilize the space inside the housing 10, thereby reducing the space occupied by the micro switch 50 and the punching assembly 20 in the width or length direction of the housing 10, thereby reducing the width or length of the housing 10, and reducing the overall space occupied by the punching device 100.

[0062] Furthermore, the micro switch 50 is welded to the clip assembly 20. In this way, by directly welding the micro switch 50 to the clip assembly 20, not only can the electrical connection between the micro switch 50 and the clip assembly 20 be ensured, but also the connection strength between the micro switch 50 and the clip assembly 20 can be ensured, so as to prevent the micro switch 50 from being separated during transportation or use and affecting the service life.

[0063] Of course, in other embodiments, the micro switch 50 can also be connected to the punching assembly 20 by means of screws, buckles, etc.

[0064] Combined with reference Figure 1 In one embodiment of the punching device 100 of the present invention, the conductive member 40 is arranged on the side of the punching component 20 facing away from the display window 121; with such a configuration, the conductive member 40 and the punching component 20 can be reasonably arranged in the thickness direction of the shell 10 to make full use of the space inside the shell 10, thereby further reducing the space occupied by the conductive member 40 and the punching component 20 in the width or length of the shell 10, thereby further reducing the width or length of the shell 10 to reduce the overall space occupied by the punching device 100.

[0065] Combined with reference Figure 1 In one embodiment of the clipping device 100 of the present invention, the conductive member 40 is welded to the clipping assembly 20; by so configuring, by directly welding the conductive member 40 to the clipping assembly 20, not only can the conductive member 40 and the clipping assembly 20 be electrically connected, but also the connection strength between the conductive member 40 and the clipping assembly 20 can be ensured, so as to prevent the conductive member 40 from detaching during transportation or use, thereby disconnecting the circuit between the conductive member 40 and the clipping assembly 20, thereby failing to supply power to the clipping assembly 20.

[0066] Combined with reference Figure 1 In one embodiment of the card punching device 100 of the present invention, the card punching component 20 includes a circuit board 21 and a display 22, the circuit board 21 is arranged opposite to the display window 121, the display 22 is arranged on the surface of the circuit board 21 facing the display window 121, and is electrically connected to the circuit board 21, and the display 22 has the display screen 221; the conductive member 40 is arranged on the surface of the circuit board 21 facing away from the display window 121, and is electrically connected to the circuit board 21; the socket 30 is arranged on the surface of the circuit board 21 facing the display window 121, and is electrically connected to the circuit board 21; the wireless module 23 is arranged on the surface of the circuit board 21 facing the display window 121, and is electrically connected to the display 22.

[0067] With such an arrangement, the conductive member 40 can provide external power to the circuit board 21, and the circuit board 21 can provide power to the display 22, the wireless module 23 and the socket 30 at the same time, and the wireless module 23 can also be used to update the display screen 221 on the display 22 in real time to display the QR code.

[0068] Combined with reference Figure 1 In one embodiment of the punching device 100 of the present invention, the shell 10 includes a bottom plate 11 and a front shell 12; the bottom plate 11 is provided with the through hole 111; the front shell 12 is covered on the bottom plate 11 and is enclosed with the bottom plate 11 to form the installation cavity, and the front shell 12 has the display window 121 and is provided with the insertion hole 122.

[0069] With such arrangement, during the assembly of the punching device 100, the base plate 11 and the front shell 12 can be disassembled first, so that the punching assembly 20, the socket 30 and the conductive member 40 can be installed on the base plate 11, and then the front shell 12 can be covered on the base plate 11 to complete the quick assembly of the punching device 100.

[0070] Specifically, the front shell 12 can be detachably connected to the bottom plate 11 by means of screws, buckles, etc.

[0071] In addition, a support member 113 is protruding from the surface of the bottom plate 11 facing the front shell 12 , and the punching assembly 20 is sandwiched between the support member 113 and the inner side surface of the front shell 12 facing the bottom plate 11 .

[0072] With such arrangement, during the assembly process, the support member 113 and the front shell 12 can be used to directly clamp and fix the punching assembly 20, without the need to use other auxiliary structures such as screws to fix the punching assembly 20. Moreover, when disassembling the punching assembly 20, the front shell 12 can be opened to remove the punching assembly 20, so as to simplify the disassembly and assembly process of the punching assembly 20 and effectively improve the disassembly and assembly efficiency.

[0073] Specifically, the two opposite sides of the punch assembly 20 are respectively in contact with the side of the support member 113 facing away from the bottom plate 11 and the inner surface of the front shell 12 facing the bottom plate 11 .

[0074] Furthermore, the support member 113 is disposed around the circumference of the bottom plate 11. This arrangement can increase the contact area between the support member 113 and the clamping assembly 20, so as to further enhance the clamping and fixing strength of the clamping assembly 20.

[0075] Furthermore, the support member 113 is disposed close to the periphery of the bottom plate 11 , and the conductive member 40 is located in a space surrounded by the support member 113 .

[0076] In this way, by arranging the support member 113 close to the periphery of the base plate 11, the support member 113 can be in full contact with the outer periphery of the punching assembly 20 facing the support member 113, so as to fully ensure the support balance of the punching assembly 20 by the support member 113; in addition, by utilizing the space surrounded by the conductive member 40, the internal space of the outer shell 10 can be further fully utilized to ensure the compactness of the overall structure.

[0077] In another embodiment, in conjunction with reference to Figures 5 to 8 The following will take the case where the punch card device 100 is used as a wall socket as an example for explanation:

[0078] Combined with reference Figure 5 In another embodiment of the punching device 100 of the present invention, the conductive member 40 includes at least two conductive wires, and at least two of the conductive wires are passed through the through hole 111 and protrude from the back side, so as to be electrically connected to an external power source to supply power to the punching assembly 20.

[0079] With such a configuration, when installing the punching device 100, at least two conductive wires protruding from the back of the housing 10 can be twisted or welded together with at least two pre-buried wires on the wall, respectively, to achieve electrical connection between the conductive wires and the pre-buried wires, and then provide external power to the punching assembly 20 through the conductive wires.

[0080] Specifically, at least two conductive wires may pass through the same through hole 111 of the housing 10 , or at least two through holes 111 may be provided on the housing 10 so that each conductive wire passes through one through hole 111 .

[0081] Furthermore, an additional wire may be passed through the through hole 111 of the housing 10 and electrically connected to the socket 30, and the wire may be twisted or welded together with the pre-buried wire on the wall to achieve electrical connection between the wire and the pre-buried wire, thereby providing external power to the socket 30 through the wire.
