DETAILED DESCRIPTION
[0023] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] This secure storage device uses a sliding door, such as Figure 1 , Figure 6 and Figure 7 The closure member 4 is provided with a plurality of closure members 12, 13 and 14 for closing the door opening 2. The closure member 4 is provided with a plurality of closure members 12 for closing the door opening 2. The closure member 4 is provided with a plurality of closure members 12 for closing the door opening 2. The closure member 4 is provided with a plurality of closure members 12 for closing the door opening 2. The closure member 4 is provided with a plurality of closure members 12 for closing the door opening 2.
[0025] like Figure 1 , Figure 6 and Figure 7As shown, the elastic deformation part includes a first elastic deformation block 6, a rigid sliding block 7, and a second elastic deformation block 8 which are fixed in sequence along a direction gradually away from the door leaf 3. The first elastic deformation block 6, the rigid sliding block 7, and the second elastic deformation block 8 are fixed by bonding with an adhesive. The rigid sliding block 7 is slidably connected to the closing member 4. A plurality of sliding rods 9 distributed in an array along its length direction are fixedly connected to the rigid sliding block 7. The sliding rod 9 and the rigid sliding block 7 are both made of stainless steel. The high structural strength of the stainless steel material is utilized to ensure that the rigid sliding block 7 and the sliding rod 9 have good and stable structural strength. A plurality of sliding holes 10 are provided on the closing member 4 for the sliding rod 9 to penetrate and slide. The rigid sliding is achieved through the joint action of the sliding rod 9 and the sliding hole 10. The stable sliding between the movable block 7 and the closing member 4, with the help of the sliding connection between the rigid sliding block 7 and the closing member 4, realizes the stable guiding and limiting effect on the elastic deformation process of the first elastic deformation block 6 and the second elastic deformation block 8, ensuring that the first elastic deformation block 6 and the second elastic deformation block 8 can stably perform elastic deformation under the extrusion of the door leaf 3. The first elastic deformation block 6 and the second elastic deformation block 8 are both set to silicone rubber material, and the good elastic deformation characteristics of this type of material are used to ensure that the first elastic deformation block 6 and the second elastic deformation block 8 have good and stable elastic deformation performance. When the user's hand is accidentally clamped by the door leaf 3, the first elastic deformation block 6 and the second elastic deformation block 8 can be stably squeezed and deformed, thereby achieving stable protection for the user's hand.
[0026] like Figure 1 , Figure 6 and Figure 7 As shown, a placement hole 11 facing the door leaf 3 is penetrated through the first elastic deformation block 6, and a pressure sensor 12 flush with the opening of the placement hole 11 is fixedly connected in the placement hole 11. The pressure sensor 12 is electrically connected to the PLC controller. When the user's hand is accidentally clamped, the first elastic deformation block 6 will be squeezed and deformed and pressure will be applied to the pressure sensor 12. Under the action of the pressure sensor 12, the pressure is converted into an electrical signal, which is transmitted to the PLC controller. The driving state of the driving part is controlled by the PLC controller, thereby reducing the possibility of the user's hand being clamped.
[0027] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, safety gratings 13 are fixedly connected on both sides of the length direction of the door opening 2. The safety gratings 13 are electrically connected to the PLC controller. The safety gratings 13 are used to sense the situation of the user's hand reaching into the door opening 2. When the user's hand reaches into the door opening 2, it will be sensed by the safety grating 13, and the sensed situation will be converted into an electrical signal and transmitted to the PLC controller. The driving part is controlled by the PLC controller to reduce the possibility of false start-up of the driving part and reduce the possibility of the user's hand being pinched and injured.
[0028] like Figure 1 , Figure 4 and Figure 5 As shown, a symmetrically arranged guide rail 14 is fixedly connected to the support plate 1 by means of bolt locking, and a plurality of sliders 15 sliding on the guide rail 14 are fixedly connected to the door leaf 3 by means of bolt locking. The sliding of the sliders 15 on the guide rail 14 enables stable sliding between the door leaf 3 and the guide rail 14, thereby ensuring that the door leaf 3 can slide stably relative to the support plate 1, and ensuring that the door leaf 3 can slide stably relative to the support plate 1 under the action of the driving unit, so that the door leaf 3 can stably close and open the door opening 2.
[0029] like Figure 1 and Figure 2 As shown, the driving part includes a driving motor 16 fixedly connected to the support plate 1 and a gear 17 fixedly connected to the output shaft of the driving motor 16. The driving motor 16 is fixed to the support plate 1 by bolt locking. The driving motor 16 is configured as a turbine motor. A rack 18 meshing with the gear 17 is fixedly connected to the door leaf 3 by bolt locking. The driving motor 16 is electrically connected to the PLC controller. The driving motor 16 is used to drive the gear 17 to rotate. The rotation of the gear 17 pushes the rack 18 to slide through meshing, and the sliding of the rack 18 drives the door leaf 3 to slide. The transmission of the gear 17 and the rack 18 has the characteristic of good stability to ensure that the driving motor 16 can stably drive the door leaf 3 to move.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
