[0002] With the increase of people's economic activities and the increasingly close communication between work and life, the requirements for safe storage and delivery of materials are constantly increasing. Password storage products with anti-theft functions and convenient opening will be more and more urgently used. In metallurgy, coal mining, electric power and other industries, material sampling, sample preparation, storage, delivery and handover of samples require material storage products everywhere. In order to ensure that samples are not mixed or replaced during transportation, more and more manufacturers are using material barrels with password covers for sample transportation and storage. Among the existing password barrels, one adopts a double actuator plus double buckle structure, which integrates a rechargeable battery and a control chip inside, and controls the opening of the password cover by swiping a card. This double actuator plus double buckle structure is prone to cause the lock to automatically loosen during transportation, and the seal fails. Another intelligent locking sample storage barrel uses a motor-driven belt to open and close the barrel cover. The actuator is complex, has low reliability, and is difficult to implement. Both methods use rechargeable batteries to power the actuator, which consumes a lot of power and requires frequent charging. It is unknown when the battery will run out of power, so the utilization rate is very low in actual work.

[0019] The guide plate 6 is fixed to the inner base of the cover body 1 by bolts, and grooves matching with the upper return spring 8 and the lower return spring 9 are provided at the middle positions of the top and bottom of the guide plate 6 to prevent the springs from shifting. The middle part of the guide plate 6 is provided with a first opening matched with a cylindrical pin 16, and the first opening and the cylindrical pin 16 are transitionally matched and connected, and the middle parts of the upper slider 5 and the lower slider 7 are both provided with a second opening matched with the cylindrical pin 16, and the top of the cylindrical pin 16 passes through the upper return spring 8 and is clamped in the second opening of the upper slider 5 by the shaft retaining ring, and the bottom of the cylindrical pin 16 is provided with a step protrusion, and its bottom passes through the lower return spring 8 and is clamped in the second opening of the lower slider 7 by the step protrusion. The cylindrical pin 16 connects the upper slider 5, the upper return spring 8, the guide plate 6, the lower return spring 9 and the lower slider 7 into a whole in series; under the action of external force, the upper slider 5 and the lower slider 7 respectively overcome the action of the upper return spring 8 and the lower return spring 9, and move up and down along the cylindrical pin 16 to drive the lock hook 15 to separate and bite from the outer edge 18 of the barrel body; after the external force disappears, the upper return spring 8 and the lower return spring 9 respectively drive the upper slider 5 and the lower slider 7 to reset.

[0020] The inner part of the guide plate 6 is provided with a plurality of evenly distributed guide square holes along the circumferential direction. The inner end of the lock hook 15 is slidably arranged in the guide square hole. The lower part of the outer end is provided with an arc opening engaged with the outer edge 18 of the barrel body. The top of the barrel body is rolled outward to form a circular ring structure engaged with the lock hook 15. The upper slider 5 and the lower slider 7 are both movably connected to the inner end of the lock hook 15 through the connecting rod 10. The upper slider 5 and the lower slider 7 move toward each other, and the connecting rod 10 drives the lock hook 15 to slide outward, and the lock hook 15 is separated from the outer edge 18 of the barrel body; the upper slider 5 and the lower slider 7 move in the opposite direction, and the connecting rod 10 drives the lock hook 15 to slide inward, and the lock hook 15 is engaged with the outer edge 18 of the barrel body.

[0021] One end of the connecting rod 10 is movably connected to the slider, and the other end is movably connected to the lock hook 15. Multiple connecting rods 10 can be provided, and they are selected according to the size of the barrel diameter. In this embodiment, three guide square holes are distributed on the guide plate 6, which are distributed at 120 degrees and serve as the track for the lock hook 15 to slide. There are six connecting rods 10, three of which are used to connect the upper slider 5 and the lock hook 15, and three are used to connect the lower slider 7 and the lock hook 15.

[0022] A limiting mechanism is also provided inside the cover body 1. The limiting mechanism includes a safety lock plate 13 and an electromagnetic latch 12. The safety lock plate 13 is installed on the upper slider 5 and engages with the electromagnetic latch 12. The electromagnetic latch 12 is fixed to the base of the inner cavity of the cover body 1 by bolts. When the electromagnetic latch 12 is energized, it is separated from the safety lock plate 13; when the electromagnetic latch 12 is de-energized, it engages with the safety lock plate 13. The upper and lower parts of the safety lock plate 13 are respectively provided with an upper engaging opening 13.1 and a lower engaging opening 13.2. When the electromagnetic latch 12 engages with the lower engaging opening 13.2, the upper slider 5 is restricted in a high position and cannot move downward, and the locking part is in a locked working state (see Figure 5 ); When the electromagnetic latch 12 is engaged with the upper engagement opening 13.1, the upper slider 5 is restricted in the low position and cannot move upward, and the locking portion is in the open working state (see Figure 6 ), at this time, the external force is removed, the button is in a pressed self-locking state, the lock hook 15 is separated from the outer edge of the barrel, and the barrel cover can be removed. A reset spring is designed between the two sliders. After the external force disappears, the two sliders automatically reset, the electric plug resets, and the barrel cover is in a password locked state. Before the external force disappears, the electric plug resets, and the barrel cover is in a state of opening and waiting to be removed. The actuator is simpler, and the limiting effect of the electromagnetic plug 12 makes the lock buckle have an anti-pry function, which is more reliable to use.

[0023] A control circuit is also provided inside the cover body 1. The control circuit includes a card swiping induction coil 19, a chip 21, a circuit board and an elastic charging copper column 4. The elastic charging copper column 4 is connected to an external power source and is distributed on two concentric rings. The charging copper column is selected instead of the charging socket to facilitate automatic connection with the external power source. The elastic charging copper column 4 is divided into positive and negative poles, and the voltage is generally 12V and 24V. The control circuit is electrically connected to the electromagnetic plug 12 to control the legal opening and closing of the electromagnetic plug 12. The top of the upper slider 5 is connected to the cover opening button 3, which is a cavity structure, and the card swiping induction coil 19 is arranged in the cavity of the cover opening button 3. A plurality of small holes are provided on the top of the upper slider 5, and a plurality of protruding cylinders are provided at the bottom of the cover opening button 3. The bottom ends of the cylinders are correspondingly embedded in the small holes to prevent the rotation of the cover opening button 3 from causing damage to the card swiping coil circuit. In the process of opening and closing the cover, the cover opening button 3 is driven mechanically or manually by external force, and no electric drive is required. Under the action of external force, the upper slider 5 and the lower slider 7 slide axially, and the connecting rod 10 connects the upper and lower sliders 7 and the lock hook 15. The upper slider 5 and the lower slider 7 drive the lock buckle to slide radially through the connecting rod 10. The electric drive after password decoding only opens the electromagnetic latch 12, and the electromagnetic latch 12 restricts the sliding of the upper slider 5 and the lower slider 7, that is, the latch is not found, and the slider cannot be moved by external force.

[0024] The barrel is a carrier for placing materials, usually a conical barrel. Of course, the barrel can also be cylindrical, square, etc. according to the size and shape of the materials to be placed. The sample identity chip 21 is installed at the bottom of the barrel to record the identity information of the material. The middle of the barrel bottom is a concave structure so that the chip 21 does not protrude from the bottom of the barrel after installation to prevent wear during use. When the lid needs to be opened, the program controls the external power supply to automatically connect after the material information is automatically identified on the lid opening machine, automatically scan the barrel cover password, and automatically open the lid, which is conducive to automated assembly line operations, realizing the automatic identification of the same sample, and the assembly line operations of opening the lids of 2 or more barrels, pouring materials, etc.

[0025] In order to effectively isolate it from the outside world, a groove for installing an O-ring is opened on the barrel cover. A silicone sealing ring is installed in the groove, which is anti-aging and has good sealing.

[0026] In order to better illustrate the present invention, the working process is specifically described below: Opening process: When the password cover needs to be opened, first the external charging ring is connected to the elastic copper charging column of the barrel cover, and the electromagnetic plug 12 is energized by swiping the card, and the electromagnetic plug 12 is separated from the engagement opening 13.2 of the safety lock plate 13. At this time, the external force presses the opening button 3 for 4 seconds, and the electromagnetic plug 12 automatically loses power, and the electromagnetic plug 12 is engaged with the engagement opening 13.1 of the safety lock plate 13. The button is in a pressed and held state. At this time, the barrel cover can be removed to complete the opening action.

[0027] Capping process: First, the external mechanism sends the password cover to the top of the barrel body, and the charging ring is connected to the elastic copper charging column of the barrel cover. At this time, the electromagnetic latch 12 is energized by swiping the card, and the electromagnetic latch 12 is separated from the engagement opening 13.2 under the safety lock plate 13, and the sliding limit of the slider is released. When the lock hook 15 on the barrel cover contacts the outer edge of the barrel, the lock hook 15 slides radially under the reaction force of the outer edge 18 of the barrel body, and the upper and lower sliders 7 slide axially driven by the connecting rod 10 until the lock hook 15 is completely engaged with the circular ring on the outer edge of the barrel. At this time, the reset spring pushes the upper and lower sliders 7 to slide axially and return to the initial position, the electromagnetic latch 12 loses power, and the electromagnetic latch 12 re-engages with the engagement opening 13.2 under the safety lock plate 13, re-limiting the sliding of the slider, and the capping is completed.

[0028] It should be emphasized that the double slider and single guide plate 6 of the present embodiment can be evolved into a single slider and single guide plate 6 and a double slider and double guide plate 6 structure. By changing the connection method between the connecting rod 10 and the locking hook 15, the radial sliding of the locking hook 15 can also be evolved into a rotational motion. At the same time, the engagement of the locking hook 15 with the outer edge of the barrel can also be evolved into the engagement of the locking hook 15 with the inner edge of the barrel.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
