Detailed Description of the Embodiment
[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] The following is a further detailed description of this application in conjunction with the attached Figures 1-6 drawings,
[0033] An embodiment of the present application discloses an intelligent biological evidence sample cabinet, including a cabinet body 1, and a plurality of electric slide drawers 2 which are independently and automatically opened or closed under the control of an electronic control system are arranged on the cabinet body 1;
[0034] The electric slide drawer 2 includes a gear A 4 and a gear B 5 meshed with a toothed belt 3, a motor 6 for driving the gear A 4 to rotate, and a drawer 8 that slides in or out of a drawer slot 7 by following the transmission of the toothed belt 3;
[0035] The motor 6 drives the gear A 4 to rotate to drive the toothed belt 3 to drive, so that the drawer 8 slides into the drawer slot 7 to store the evidence samples placed in the drawer 8;
[0036] The motor 6 drives the gear A 4 to rotate to drive the toothed belt 3 to drive, so that the drawer 8 slides out of the drawer slot 7 to facilitate authorized personnel to access the evidence samples.
[0037] When the motor 6 does not operate, the gear A 4 does not rotate, and it is impossible for a person to pull the drawer 8 out of the drawer slot 7. The automatic opening and closing of the electric slide drawer 2 reduces the need for manual operation and improves efficiency. The independent control and automatic locking function of the electric slide drawer 2 helps to prevent unauthorized access and potential evidence tampering. When it is necessary to access the evidence samples in the drawer 8, authorized personnel can easily control the automatic sliding out of the drawer 8 through the electronic control system, which can be operated quickly and conveniently. The compact design of the slide drawer 8 enables the evidence sample cabinet to store more physical evidence in a limited space. The use of the automatic slide drawer 8 reduces the risk of physical damage to the evidence samples during manual access.
[0038] The motor 6 is fixed on a partition 9 of the cabinet body 1 and is located in the drawer slot 7. A bearing seat A 10 rotatably connected to the output shaft of the motor 6 is fixedly arranged at the top of the partition 9, and the output shaft of the motor 6 is fixedly connected to the gear A 4.
[0039] Placing the motor 6 in the drawer slot 7 can make the most of the space because there is no need to reserve space for the motor 6 outside the cabinet body 1. This design makes the entire evidence sample cabinet more compact and helps to save space. The motor 6 is located in the drawer slot 7, reducing the possibility of personnel contacting the motor 6, thereby improving the operation safety.
[0040] Through the connection between the bearing seat A 10 and the gear A 4, the design of the transmission system is simplified and the number of components is reduced. The bearing seat A 10 provides stable support and rotation, ensuring efficient transmission between the output shaft of the motor 6 and the gear A 4. The effective use of the bearing seat A 10 reduces the wear of the gear and other transmission components and extends the service life of the equipment.
[0041] The axle of the gear B5 is rotatably arranged on the bearing block B11 at the top of the partition plate 9, and the gear A4 and the gear B5 are respectively located at both ends of the drawer slot 7.
[0042] The gear A4 and the gear B5 are respectively located at both ends of the drawer slot 7, which can balance the load and improve the stability of the whole system. The two gears are located at both ends of the drawer slot 7, which can achieve more efficient transmission and reduce energy loss. Such a layout makes the sliding in and out of the drawer 8 smoother and simplifies the operation process.
[0043] The buckle 12 fixedly arranged on the toothed belt 3 is fixed to the bottom of the drawer 8.
[0044] The buckle 12 is fixed to the bottom of the drawer 8 and fixedly connected to the toothed belt 3, and the toothed belt 3 drives the drawer 8 to translate.
[0045] When the drawer 8 slides out or slides into the drawer slot 7, it slides along the slide rail 13 and the guide wheel 14 at the top of the partition plate 9 for guiding.
[0046] The bottom of the drawer 8 is fixedly provided with a slider 15 that cooperates with the slide rail 13 for guiding and sliding.
[0047] The guide wheel 14 is rotatably arranged on the wheel frame 16, and the wheel frame 16 is fixed to the bottom of the partition plate 9 and located at one end far from the motor 6.
[0048] The slide rail 13 and the guide wheel 14 ensure the precise guiding of the drawer 8 during the movement process and avoid the deviation of the drawer 8 during the movement process. The presence of the slide rail 13 and the guide wheel 14 enables the drawer 8 to move smoothly when sliding out or sliding in, reducing vibration and noise. The design of the slide rail 13 and the guide wheel 14 can reduce the direct contact between the drawer 8 and other parts of the cabinet body 1, thereby reducing wear.
[0049] The setting of the slider 15 makes the drawer 8 easier to be pushed and pulled, providing a more convenient operation experience. Due to the presence of the slider 15 and the guide wheel 14, the sliding of the drawer 8 is smoother.
[0050] Two buffer blocks 17 are fixedly arranged on both sides of the bottom of the rear side of the drawer 8, and the partition plate 9 is provided with a limit plate A18 for limiting the drawer 8 sliding into the drawer slot 7 and a limit plate B19 for limiting the drawer 8 sliding out of the drawer slot 7; the limit plate A18 and the limit plate B19 respectively cooperate with the buffer blocks 17 for buffer limiting.
[0051] The buffer blocks 17 can play a role in shock absorption when the drawer 8 slides in or out, protecting the physical evidence in the drawer 8 from being affected by vibration.
[0052] The buffer block 17 cooperates with the limit plate A 18 and the limit plate B 19 to limit the movement of the drawer 8, preventing the drawer 8 from sliding in or out excessively due to inertia, and ensuring the safety of operation.
[0053] The limit plate A 18 and the limit plate B 19 can accurately limit the sliding position of the drawer 8, ensuring that the drawer 8 can accurately stop at the specified position. The limit plate A 18 and the limit plate B 19 protect the drawer 8 from damaging the slide rail 13 or other parts of the cabinet body 1 due to excessive sliding.
[0054] The buffer limit ensures that the drawer 8 can stop smoothly when reaching the limit, rather than braking suddenly, further protecting the physical evidence in the drawer 8. Through the buffer limit, the impact on the slide rail 13 and the drawer 8 itself when the drawer 8 reaches the limit is reduced, thereby reducing wear. The combined use of the limit plate and the buffer block 17 improves the overall safety of the drawer 8 operation and ensures the safety of the physical evidence.
[0055] For this intelligent biological physical evidence storage cabinet, the motor 6 is located inside the partition 9 of the cabinet body 1, saving space, reducing human contact, and improving operation safety. The connection between the bearing seat A 10 and the gear A 4 simplifies the design of the transmission system, reduces the number of components, reduces wear, and extends the service life of the equipment. The design of the gear B 5 balances the load, improves the stability of the system, realizes more efficient transmission, reduces energy loss. The setting of the clip 12 fixes the bottom of the drawer 8 and cooperates with the toothed belt 3 to ensure the stable and smooth movement of the drawer 8. The design of the slide rail 13 and the guide wheel 14 provides precise guidance and smooth movement, reduces vibration and noise, and protects the drawer 8 and the cabinet body 1 from wear. The cooperation between the buffer block 17 and the limit plate provides shock absorption and limit functions, protecting the physical evidence in the drawer 8 from damage and ensuring the safety of operation and the accuracy of the drawer 8.
