[0039] The present invention provides a card box 100 , which has good safety in use.

[0040] Reference Figures 1 to 5 The card box 100 proposed in the present invention includes a box body 110, and the box body 110 includes a front panel 111, two side panels 112 connected to the front panel 111, a top panel 113 and a bottom panel 114 connected to the front panel 111, and a card issuing port 115 is provided on the front panel 111. The card box 100 also includes a locking mechanism installed in the box body 110, and the locking mechanism includes a baffle 120, a fixing plate 130, two first locking members 140, a first reset member (not shown) and two second locking members 150. The baffle 120 can be installed on the box body 110 in an upside-down manner to control the opening and closing of the card issuing port 115. The upper surface of the baffle 120 is provided with a baffle 121 and a limiting groove 122 (as shown in the figure). Figure 6 The limiting groove 122 is located between the rotation axis of the door stopper 120 and the front panel 111. The fixing plate 130 is installed above the door stopper 120. The fixing plate 130 is provided with a first slide groove 131 and a second slide groove 132 extending from one side plate 112 of the box body 110 toward the other side plate 112 in the vertical direction. Figure 7 The first slide groove 131 is located between the front panel 111 and the second slide groove 132. The two first locking members 140 are installed on the fixing plate 130 (as shown) at intervals in the direction from one of the side panels 112 to the other side panel 112. Figure 4As shown in the figure, one of the first locking members 140 is slidably installed in the first slide groove 131 and is carried by the fixed plate 130, and the lower end of the first locking member 140 extends out of the first slide groove 131 and is located directly above the limiting groove 122. The first reset member is connected to the first locking member 140 located above the limiting groove 122 for its elastic reset. The two second locking members 150 are installed on the fixed plate 130 at intervals in the direction from one of the side plates 112 to the other side plate 112, and one of the second locking members 150 is slidably installed in the second slide groove 132 and is carried by the fixed plate 130, and the lower end of the second locking member 150 extends out of the second slide groove 132 and has a first position for stopping the block 121 and a second position for avoiding the block 121.

[0041] Specifically, the box body 110 is a cubic structure and has an inner cavity. Figure 2 and Figure 3 , a baffle 117 is disposed in the inner cavity, and the baffle 117 divides the inner cavity into a first accommodating cavity and a second accommodating cavity, wherein the first accommodating cavity is used to accommodate the card 300, and the second accommodating cavity is used to install the locking mechanism. The first accommodating cavity is formed by the baffle 117 and the front panel 111, and a gap is left between the lower end of the baffle 117 and the bottom plate 114 of the box body 110 for the card 300 to pass through. The front panel 111 of the box body 110 also has a key hole 116 (such as Figure 1 As shown), for the key plate 210 to be inserted.

[0042] There are many ways to install the baffle 120 on the box body 110 so that it can be turned upside down. For example, in this embodiment, a rotating shaft 118 is provided between the two side plates 112 of the box body 110, and the rotating shaft 118 is a straight shaft. The baffle 120 is passed through the rotating shaft 118 and can rotate along the rotating shaft 118. In other embodiments, a crankshaft can also be provided on the baffle 117, and the baffle 120 can be rotatably installed on the crankshaft.

[0043] The shape of the stopper 121 can be various, for example, the stopper 121 can be set in a block shape, or in a strip shape extending from one side plate 112 of the box body 110 toward the other side plate 112. The stopper 121 can be located between the rotation axis of the stopper 120 and the front panel 111, or above the rotation axis of the stopper 120, or on the side of the rotation axis of the stopper 120 away from the front panel 111, and no specific limitation is made here. The limiting groove 122 is located between the rotation axis of the baffle door 120 and the front panel 111. In this way, when the baffle door 120 is flipped upward, the first locking member 140 can be inserted into the corresponding limiting groove 122, thereby locking the first locking member 140. The key plate 210 installed on the card issuing machine 200 is locked through the first locking member 140 to prevent the key plate 210 from being pulled out, thereby achieving the card box 100 being locked on the card issuing machine 200 during the card issuing process, thereby improving the safety of the card box 100.

[0044] The fixing plate 130 is installed above the baffle 120, wherein the fixing plate 130 is fixed to the two side plates 112 of the box body 110. Figure 4 As shown, in this embodiment, the two sides of the fixing plate 130 extend downward to form two mounting parts, and the two ends of the rotating shaft 118 are inserted into the two mounting parts. The upper surface of the fixing plate 130 is provided with a key position corresponding to the key port 116, wherein the key position is formed by the two first locking members 140 and the two second locking members 150. If the card box 100 is installed on the card issuing machine 200, the key plate 210 on the card issuing machine 200 can be inserted into the key position. During the process of inserting the key plate 210 into the key position, the key plate 210 will drive the first locking member 140 and the second locking member 150 to slide. When the second locking member 150 slides from the first position to the second position, the stopper 120 can rotate freely. In this way, the card 300 in the box body 110 can drive the stopper 120 to flip upward, and the card issuing port 115 is opened, and the card 300 can be issued smoothly.

[0045] Furthermore, during the card issuing process, the lower end of the first locking member 140 is inserted into the corresponding limiting groove 122 because the blocking door 120 is turned upward, thereby preventing the first locking member 140 from sliding along the first sliding groove 131, that is, locking the first locking member 140. At this time, the first locking member 140 can lock the key plate 210, preventing the key plate 210 from being withdrawn, thereby locking the card box 100 on the card issuing machine 200.

[0046] It should be explained that when the second locking member 150 is in the first position, the lower end of the second locking member 150 is in contact with the side of the stopper 121 away from the front panel 111 (eg, Figure 2As shown), at this time, the blocking door 120 closes the card issuing port 115, and the blocking door 120 cannot rotate freely; when the second locking member 150 is in the second position, the lower end of the second locking member 150 does not abut against the stopper 121 (as shown in FIG. Figure 3 As shown), at this time, the blocking door 120 can rotate freely to open the card issuing port 115.

[0047] One of the first locking members 140 is slidably mounted in the first slide groove 131, and the other first locking member 140 may be slidably mounted in the first slide groove 131, or may be fixedly mounted on the fixed plate 130. Similarly, one of the second locking members 150 is slidably mounted in the second slide groove 132, and the other second locking member 150 may be slidably mounted in the second slide groove 132, or may be fixedly mounted on the fixed plate 130.

[0048] There are many ways to install the first reset member, wherein the first reset member can be arranged between the two first locking members 140, for example, one end of the first reset member is connected to one of the first locking members 140, and the other end is connected to the other first locking member 140. Of course, the first reset member can also be arranged between the first locking member 140 and the fixing plate 130, for example, one end of the first reset member is connected to the fixing plate 130, and the other end is connected to the corresponding first locking member 140. Specifically, the first reset member can be a spring or silicone.

[0049] In this embodiment, the cross section of the head of the key plate 210 is hexagonal. Thus, when the head of the key plate 210 is just inserted into the key position, the first locking member 140 is pushed by the key plate 210 and slides to the side away from the key plate 210; and when the head of the key plate 210 is inserted into the key position, the first locking member 140 can slide toward the direction close to the key plate 210 under the action of the rebound force of the first restoring member, and abut against the key plate 210 to lock the key plate 210.

[0050] The card box 100 of the present invention adopts a flap door 120 that can be flipped up and down at the card issuing port 115 of the box body 110 of the card box 100 to control the opening and closing of the card issuing port 115, wherein the upper surface of the flap door 120 is provided with a stopper 121 and a limit groove 122, the fixing plate 130 is installed above the flap door 120, the fixing plate 130 is penetrated by a first slide groove 131 and a second slide groove 132, the first slide groove 131 and the second slide groove 132 are extended along one side plate 112 of the box body 110 toward the other side plate 112, the two first locking members 140 are spaced apart on the fixing plate 130, and one of the first locking members 140 is spaced apart from the other side plate 112 of the box body 110. The first locking member 140 is slidably installed in the first sliding groove 131 and carried by the fixing plate 130. The lower end of the first locking member 140 extends out of the first sliding groove 131 and is located directly above the limiting groove 122. The first reset member is connected to the first locking member 140 located above the limiting groove 122 for its elastic reset. Two second locking members 150 are spaced apart on the fixing plate 130, wherein one of the second locking members 150 is slidably installed in the second sliding groove 132 and carried by the fixing plate 130. The lower end of the second locking member 150 extends out of the second sliding groove 132 and has a first position of stopping the stopper 121 and a second position of avoiding the stopper 121. Thus, before the card box 100 is loaded into the card issuing machine 200, since at least one of the second locking members 150 is located at the first position to prevent the blocking door 120 from rotating, the card issuing port 115 is closed to prevent the card 300 in the card box 100 from falling out; after the card box 100 is installed in the card issuing machine 200, the key plate 210 on the card issuing machine 200 is inserted into the corresponding key position, and the second locking member 150 is driven to slide from the second position to the first position, so that the blocking door 120 can rotate freely. At this time, The cards 300 in the card box 100 can be issued smoothly; during the card issuance process, the card 300 will drive the baffle door 120 to flip upward and open the card issuance port 115. As the baffle door 120 flips upward, the lower end of the first locking member 140 will be inserted into the corresponding limit groove 122, thereby locking the first locking member 140. The key plate 210 is locked through the first locking member 140 to lock the card box 100 on the card issuing machine 200, thereby improving the safety of the card box 100.

[0051] In a preferred embodiment, the two first locking members 140 are both slidably installed in the first slide groove 131, and the lower ends of the two first locking members 140 extend out of the first slide groove 131, and the upper surface of the fixed plate 130 is provided with two limiting grooves 122, and each limiting groove 122 is located directly below a corresponding first locking member 140.

[0052] The two second locking members 150 are both slidably installed in the second sliding groove 132 , and the lower ends of the two second locking members 150 extend out of the second sliding groove 132 to have a first position for stopping the stopper 121 and a second position for avoiding the stopper 121 .

[0053] Reference Figure 7 In order to improve the support strength of the fixing plate 130, the first sliding groove 131 may include two first sub-grooves 1311 arranged at intervals. One of the first locking members 140 is slidably installed in one of the first sub-grooves 1311, and the other first locking member 140 is slidably installed in the other first sub-groove 1311.

[0054] Similarly, the second sliding groove 132 may also include two second sub-grooves 1321 spaced apart from each other. One of the second locking members 150 is slidably installed in one of the first sub-grooves 1311 , and the other second locking member 150 is slidably installed in the other second sub-groove 1321 .

[0055] Furthermore, two first mounting grooves 133 are formed on the upper surface of the fixing plate 130, and the two first mounting grooves 133 are respectively located on both sides of the first sliding groove 131. The first resetting member is installed in the first mounting groove 133, and one end of the first resetting member is connected to the side wall of the first mounting groove 133, and the other end is connected to the corresponding first locking member 140. In this embodiment, a mounting column 135 is provided on a side wall of the first mounting groove 133 opposite to the first locking member 140, for mounting one end of the first resetting member.

[0056] Furthermore, the locking mechanism further includes two second reset members, each of which is connected to a corresponding second locking member 150, so that the second locking member 150 can be reset elastically. The second reset member can be arranged between the two second locking members 150, for example, one end of the second reset member is connected to one of the second locking members 150, and the other end is connected to the other second locking member 150. Of course, the second reset member can also be arranged between the second locking member 150 and the fixing plate 130, for example, the upper surface of the fixing plate 130 is provided with a second mounting groove 134, the second reset member is installed in the second mounting groove 134, and one end of the second reset member is connected to the inner side wall of the second mounting groove 134, and the other end is connected to the corresponding second locking member 150.
