Description

Technical Field

[0001] The present invention belongs to the technical field of sampling and sample encapsulation, and relates to a sample bucket and its lid structure, in particular to an automatically locking and unlocking lid structure and a sample bucket having the same. Background Art

[0002] Currently, in most samplings at home and abroad, the final sample encapsulation is to encapsulate the sample in a sample bucket that is not easy to open. Most of the currently used sample buckets are crimped and coded sample buckets. For the crimped and coded sample buckets, the lid needs to be opened in a destructive manner when opening the lid, and the lid cannot be reused. Moreover, the sample bucket is in an open state inside the sample divider, resulting in a large loss of moisture.

[0003] In summary, how to effectively solve the problems of non-reusability of the sample bucket lid, high cost, and large loss of moisture in the sample in the bucket is an urgent problem for those skilled in the art at present.

[0004] Therefore, in view of the defects existing in the prior art, there is an urgent need to develop a new type of sample bucket. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects existing in the prior art, and provide an automatically locking and unlocking lid structure and a sample bucket having the same, which can achieve a perfect structure between the lid structure and the barrel body, and can have two states of unlocking and locking, and can effectively solve the problems of non-reusability of the sample bucket, high cost, and large loss of moisture in the sample in the bucket.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] An automatically locking and unlocking lid structure, which is internally provided with a circuit board and an automatically locking and unlocking structure. The automatically locking and unlocking structure is characterized in that it includes a motor connected to the circuit board, a screw rod is connected to the output shaft of the motor, and a nut is sleeved on the screw rod. A spring is also sleeved on the screw rod, and both ends of the spring are respectively connected to the nut and the lock core. The forward and reverse rotation of the motor will drive the nut to move left and right, and the left and right movement of the nut will drive the spring to stretch and contract, and the spring will drive the lock core to move left and right.

[0008] Preferably, the automatically locking and unlocking mechanism further includes an infrared sensor disposed on the side of the screw rod and connected to the circuit board, and the infrared sensor is used to detect the position of the lock core.

[0009] Preferably, there are two groups of the infrared sensors, and the two groups of infrared sensors are arranged along the axial direction of the screw rod.

[0010] Preferably, two of the automatic opening and closing structures are provided inside the barrel cover structure with automatic opening and closing, and the two automatic opening and closing structures are symmetrically arranged with respect to the center of the barrel cover structure.

[0011] Preferably, a battery is further provided inside the barrel cover structure with automatic opening and closing, and the battery is used to supply power to the circuit board, the motor and the infrared sensor.

[0012] Preferably, a mushroom head is provided on the top surface of the barrel cover structure with automatic opening and closing.

[0013] Preferably, a wireless charging coil is provided inside the mushroom head, and the wireless charging coil is used to charge the battery.

[0014] Preferably, the circuit board has a Bluetooth module to facilitate wireless communication with other devices.

[0015] In addition, the present invention also provides a sample barrel, which includes the above-mentioned barrel cover structure with automatic opening and closing and a barrel body that cooperates with the barrel cover structure.

[0016] Preferably, a folded edge that turns inward is provided at the joint of the barrel body and the barrel cover structure, and the folded edge is used to clamp the protruding lock core.

[0017] Compared with the prior art, the barrel cover structure with automatic opening and closing of the present invention and the sample barrel having the same have one or more of the following beneficial technical effects:

[0018] 1. The present invention can automatically control the extension and retraction of the lock core, so that there can be two states of unlocking and locking. In the unlocking state, the barrel cover structure and the barrel body can be easily separated. In the locking state, since the lock core clamps the folded edge at the upper end of the barrel body, the barrel cover and the barrel body are locked and difficult to separate. Thus, a perfect fit between the barrel cover structure and the barrel body can be achieved.

[0019] 2. The barrel cover structure and the barrel body of the sample barrel of the present invention can have two states of separation and locking, so that the problems of high cost and large loss of moisture in the sample in the barrel due to the inability to reuse the sample barrel can be effectively solved.

[0028] To solve the problems existing in the sample barrels in the prior art, the inventor has conducted long-term research and invented an automatic opening and closing barrel cover structure and a sample barrel having the same.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0031] As Figures 1-6 shown, the automatic opening and closing barrel cover structure G of the present invention is circular and includes a top surface 1 and a bottom surface 2. Among them, a mushroom head 11 is provided on the top surface 1 to facilitate clamping of the barrel cover structure G. A plurality of connection holes are provided on the bottom surface 2 to facilitate connection of a sealing plate. Through the sealing plate, a sealed space is formed between the top surface 1, the bottom surface 2, and the sealing plate.

[0032] Among them, a circuit board 3 and an automatic opening and closing structure are provided inside the sealed space. The automatic opening and closing structure includes a motor 5 connected to the circuit board 3. The motor 5 is fixed inside the sealed space and a screw rod 6 is connected to the output shaft of the motor 5, so that the motor 5 can drive the screw rod 6 to rotate.

[0033] A nut 9 is sleeved on the screw rod 6. The rotation of the screw rod 6 can drive the nut 9 to move left and right.

[0034] A spring 10 is also sleeved on the screw rod 6, and both ends of the spring 10 are respectively connected to the nut 9 and the lock core 7. The lock core 7 can extend out of and retract into the side part of the sealed space.

[0035] In this way, the forward and reverse rotation of the motor 5 drives the nut 9 to move left and right, and the left and right movement of the nut 9 drives the spring 10 to expand and contract, and the spring 10 drives the lock core 7 to move left and right, so that the lock core 7 extends out of or retracts into the side part of the sealed space, thereby realizing unlocking and locking.

[0036] Preferably, the automatic unlocking and locking mechanism further includes an infrared sensor 8 arranged on the side of the screw rod 6 and connected to the circuit board 3. The infrared sensor 8 is used to detect the position of the lock core 7.

[0037] More preferably, there are two groups of the infrared sensors 8, and the two groups of the infrared sensors 8 are arranged along the axial direction of the screw rod 6.

[0038] Thus, when the lock core 7 is completely retracted, it will block all two groups of the infrared sensors 8, and when the lock core 7 extends out completely, it will make the two groups of the infrared sensors 10 unblocked and all conduct. In this way, the position of the lock core 7 can be detected by the infrared sensor 8, and the detection result is sent to the circuit board 3, so that the circuit board 3 can control the rotation and steering of the motor 5 according to the detection result, thereby realizing the automatic control of unlocking and locking.

[0039] In the present invention, preferably, two automatic unlocking and locking structures are arranged inside the sealed space, and the two automatic unlocking and locking structures are symmetrically arranged with respect to the center of the barrel cover structure G. Thus, the barrel cover structure G and the barrel body S can be locked together more firmly and have better sealing performance.

[0040] More preferably, a battery 4 is further arranged inside the sealed space. The battery 4 is used to supply power to the circuit board 3, the motor 5 and the infrared sensor 8. Thus, it can work independently without an external power source.

[0041] Even more preferably, a wireless charging coil 12 is arranged inside the mushroom head 11. The wireless charging coil 12 is used to charge the battery 4. Thus, it can be wirelessly charged, making charging more convenient.

[0042] In addition, in the present invention, preferably, the circuit board 3 has a Bluetooth module. Thus, the circuit board 3 can perform wireless communication with other devices. In this way, other devices can wirelessly send instructions to control unlocking and locking from the outside.

[0043] As shown in Figure 7 and 8 the sample bucket of the present invention includes the bucket lid structure G with automatic opening and locking and a bucket body S cooperating with the bucket lid structure G.

[0044] Among them, as shown in Figure 8 a folded edge 0 that is folded inward is provided at the joint of the bucket body S and the bucket lid structure G. The folded edge 0 is used to catch the protruding lock core 7.

[0045] Specifically, the motor 5 is fixed and can rotate forward and backward. Its forward and backward rotation can drive the nut 9 to move left or right on the screw rod 6. The spring 10 is installed between the movable lock core 7 and the nut 9 and is subjected to the acting forces of the lock core 7 and the nut 9.

[0046] Taking the automatic opening and locking structure on the right as an example, when the nut 9 moves to the right, it pushes the spring 10 to move to the right together. At the same time, the spring 10 generates a rightward thrust on the lock core 7, and the lock core 7 is pushed out to the right. Thus, the lock core 7 extends out and cooperates with the folded edge 0 and is buckled under the folded edge 0, thereby realizing the locking of the bucket lid structure G and the bucket body S.

[0047] At the same time, the position of the lock core 7 is restricted by the nut 9. When the nut 9 moves to the left, it pulls the lock core 7 to move left synchronously through the spring 10. Thus, the lock core 7 retracts and disengages from the buckle of the folded edge 0, thereby realizing the separation of the bucket lid structure G and the bucket body S.

[0048] Moreover, after the lock core 7 is completely retracted, it is blocked by the protruding structure provided in the top surface 1 and cannot continue to move left and retract, and the motor 5 will stop moving.

[0049] Therefore, the bucket lid structure G can cover the bucket body S to form a closed space for the bucket body S. When the lock core 7 is in the extended state, the bucket lid structure G cannot be separated from the bucket body S. When the lock core 7 is in the retracted state, the bucket lid structure G can be easily separated from the bucket body S.

[0050] The present invention can automatically control the extension and retraction of the lock core, so that there can be two states of unlocking and locking. In the unlocking state, the bucket lid structure and the bucket body can be easily separated. In the locking state, since the lock core catches the folded edge at the upper end of the bucket body, the bucket lid and the bucket body are locked and difficult to separate. Thus, a perfect fit between the bucket lid structure and the bucket body can be achieved. Moreover, the bucket lid structure and the bucket body of the sample bucket of the present invention can have two states of separation and locking, thereby effectively solving the problems of high cost due to non-reusability of the sample bucket and large loss of moisture in the sample in the bucket.

[0051] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or alterations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
