Description

Technical Field

[0001] The utility model relates to the technical field of a device for storing a bus card, in particular to a device for storing a bus card. Background Art

[0002] The principle of the tumbler: objects that are light on top and heavy on the bottom are more stable, that is, the lower the center of gravity, the more stable it is. When the tumbler is in balance in an upright position, the distance between the center of gravity and the contact point is the smallest, that is, the center of gravity is the lowest. After deviating from the equilibrium position, the center of gravity always rises. Therefore, this state of balance is a stable balance. So no matter how the tumbler swings, it will never fall.

[0003] The bus IC card is a contactless data card. It uses the chip integrated in the card to convert the induced current into direct current through the inductor coil on the card (the inductor coil is a coil wound with copper wire) at both ends of the coil through various circuits. A relatively large capacitor is then added from both ends of the direct current to keep the voltage at both ends stable. Two wires are then drawn from both ends of the coil to the chip as signal transmission lines. When approaching the card reader, the coil generates an induced voltage, which can transmit data between the card and the external database.

[0004] The payment methods for taking the bus include bus cards, boarding codes, cash payment, etc. However, for students who do not have mobile phones, the only way to take the bus is to use bus cards or cash payment. For younger students, bus cards are easy to drop, and students often need to carry not only bus cards but also keys to school, and even need to carry medicines during special needs. When there are many things, it is not only easy to miss items, but also easy to lose them. For example, when students under the age of ten are sick, they need to carry medicines. Parents often prepare their medicines at home and pack them in medicine boxes so that their children can take them directly. However, the sealing of the medicine boxes is often not enough. When the medicine boxes fall, the medicines are easy to spill, and the medicines are easy to get damp on rainy days, which is inconvenient for students to use. Therefore, based on the above, it can be seen that for younger students, a centralized storage box for smaller daily items is needed. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] Please refer to 1-4, a device for storing a bus card includes a lower shell 1, an upper shell 2 is clamped on the lower shell 1, a bus card mechanism is arranged on the top of the inner cavity of the upper shell 2, a locking block 5 is arranged in the upper shell 2, a fixing block 6 is arranged in the lower shell 1, an arc block 61 is fixedly connected to the top of the fixing block 6, an arc ring 62 is movably sleeved outside the fixing block 6, two sliding grooves 51 are provided in the locking block 5, a wedge block 54 is slidably arranged in the sliding groove 51, a screw 52 is spirally connected in the sliding groove 51, and a compression spring 53 is arranged between the screw 52 and the wedge block 54.

[0027] Specifically, when the lower shell 1 and the upper shell 2 are buckled together, the arc block 61 abuts against the two wedge blocks 54. After overcoming the elastic force of the compression spring 53, the arc block 61 enters the inner cavity of the locking block 5. The two wedge blocks 54 limit the arc block 61 in the inner cavity of the locking block 5, thereby locking the lower shell 1 and the upper shell 2. When it is necessary to unlock the lower shell 1 and the upper shell 2 to take out the items inside, it is only necessary to squeeze the locking block 5 downward so that the arc ring 62 overcomes the elastic force of the compression spring 53. After the force is applied, the arc ring 62 also enters the inner cavity of the locking block 5, and then the locking block 5 is lifted. At this time, the arc ring 62 and the arc block 61 successively withdraw from the inner cavity of the locking block 5, and there is no longer a locking relationship between the lower shell 1 and the upper shell 2. The tumbler can be opened, and the lower shell 1 and the upper shell 2 form a larger inner cavity, which can be used to store items such as keys and medicines. Several essential items for younger students can be summarized in the inner cavity to avoid the situation where essential items are forgotten to be brought.

[0028] Furthermore, a connecting rod 3 is provided in the upper shell 2 , one end of the connecting rod 3 is fixedly connected to the top end of the locking block 5 , and the other end of the connecting rod 3 passes through the upper shell 2 and is connected to a pressing block 31 .

[0029] Specifically, refer to Figure 1 , connected with the locking block 5 through the connecting rod 3 and coordinated with the setting of the pressing block 31, it is convenient for students to open the tumbler. By pressing the pressing block 31, the locking relationship between the lower shell 1 and the upper shell 2 can be unlocked.

[0030] Furthermore, the bus card mechanism includes a resin block 43, in which a chip 41 and a coil 42 are arranged, the chip 41 is electrically connected to the coil 42, and the chip 41 is placed on the inner side of the coil 42, a connecting ring plate 32 is arranged on the connecting rod 3, the connecting ring plate 32 is connected to the resin block 43 through a tension spring 34, a circular ring 33 is arranged on the connecting ring plate 32, a mounting groove 431 is opened on the resin block 43, a U-shaped sealing gasket 35 is placed in the mounting groove 431, the U-shaped sealing gasket 35 is movably sleeved on the outside of the connecting rod 3, and the circular ring 33 is pressed tightly against the U-shaped sealing gasket 35.

[0031] Specifically, refer to Figure 3, the resin block 43 is a resin block, the chip 41 and the coil 42 are placed in the melted resin, and the bus card mechanism is formed after it solidifies, and the bus card mechanism is glued to the top of the inner cavity of the upper shell 2, and the resin block 43 is provided with a through hole for the connecting rod 3 to pass through. When the tumbler is close to the bus card swiping area, the coil 42 generates an induced current, and then the chip 41 exchanges information with the card swiping terminal and completes the deduction. The connecting ring plate 32 and the connecting rod 3 are integrated into a design, and the circular ring 33 is located on the inner side of the tension spring 34. The circular ring 33 is tightly abutted against the U-shaped sealing pad 35 through the elastic force of the tension spring 34, separating the internal space of the tumbler from the outside world, ensuring that the inner cavity of the tumbler is dry, and at the same time, a tether ring 9 is fixedly connected to the upper shell 2. By tying a rope to the tether ring 9, the tumbler can be tied to a schoolbag or clothing, which can avoid the loss of the tumbler to a certain extent.

[0032] In a further embodiment, the installation sequence of the connecting rod 3 is: first, the U-shaped sealing gasket 35 is placed into the installation groove 431, and one end of the tension spring 34 is fixedly connected to the resin block 43, and then one end of the connecting rod 3 passes through the tension spring 34, the U-shaped sealing gasket 35, the resin block 43, and the upper shell 2 from the inside of the upper shell 2 in sequence and is spirally connected to the pressing block 31, and then the tension spring 34 is pulled, and the other end of the tension spring 34 is clamped on the connecting ring plate 32, so that the tension spring 34 is in a pulled state, and the ring 33 is tightly against the U-shaped sealing gasket 35.

[0033] Furthermore, the lower shell 1 is filled with a weight filler 11 .

[0034] Specifically, refer to Figure 1 By filling the lower shell 1 with a counterweight filler 11, the weight of the lower shell 1 is increased so that the center of gravity of the tumbler is located on the lower shell 1. When the tumbler falls, the lower shell 1 always lands first, which can well protect the bus card mechanism located in the upper shell 2.

[0035] Furthermore, rubber sleeves 7 are disposed outside the lower shell 1 and the upper shell 2 .

[0036] Specifically, refer to Figure 1 By connecting the rubber sleeve 7 on the lower shell 1 and the upper shell 2, not only the aesthetics of the tumbler is increased, but also its anti-fall performance is greatly enhanced.

[0037] Furthermore, a sealing gasket 8 is provided at the connection position between the lower shell 1 and the upper shell 2 .

[0038] Specifically, the sealing gasket 8 is sleeved on the lower shell 1 , and when the lower shell 1 is engaged with the upper shell 2 , the lower shell 1 and the upper shell 2 squeeze the sealing gasket 8 , so that the sealing between the lower shell 1 and the upper shell 2 is ensured.

[0039] In this utility model, reference is made to Figures 1 to 4First, when the lower shell 1 and the upper shell 2 are buckled together, the arc block 61 abuts against the two wedge blocks 54. After overcoming the elastic force of the compression spring 53, the arc block 61 enters the inner cavity of the locking block 5. The two wedge blocks 54 limit the arc block 61 in the inner cavity of the locking block 5, thereby locking the lower shell 1 and the upper shell 2. When it is necessary to unlock the lower shell 1 and the upper shell 2 to take out the items inside, it is only necessary to squeeze the locking block 5 downward so that the arc ring 62 overcomes the elastic force of the compression spring 53, so that the arc ring 62 also enters the inner cavity of the locking block 5, and then lift the upper shell 2 as a whole. At this time, the arc ring 62 and the arc block 61 successively withdraw from the inner cavity of the locking block 5, and there is no longer a locking relationship between the lower shell 1 and the upper shell 2, and the tumbler can be opened.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
