[0007] Preferably, the auxiliary component also includes a torsion spring, and the surface of the center column is connected to the torsion spring. The torsion spring is symmetrically arranged about the center line of the center column. Through the deformation of the torsion spring, the protective panel can automatically pop out and form a support after being opened to facilitate unlocking.
[0008] Preferably, the auxiliary component also includes an auxiliary lock and a gasket. An auxiliary lock is provided on the back of the protective panel. The back of the auxiliary lock is connected to the gasket. The gasket is made of rubber material. After the protective panel is closed, the gasket is pressed against the front of the keyhole to achieve precise local sealing and prevent moisture from seeping in.
[0009] Preferably, the opening and closing assembly includes a lock catch, a socket, and a latch. The front of the elastic lock core body is connected to the lock catch, the upper end of the lock catch is provided with a socket, the socket is engaged with the latch, and the latch is arranged at the lower end of the protective panel. By opening the auxiliary lock, the latch can be inserted into the socket, thereby achieving a locking effect.
[0010] Preferably, a sealing ring is connected to the back of the elastic lock core body. The sealing ring is made of rubber. By providing a back-adhesive sealing ring at the installation joint of the door lock and the box body, the problem of uneven sealing due to the traditional use of silicone pads and easy deformation during assembly can be prevented, thereby effectively improving the sealing effect.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The elastic lock core with a triple-proof structure can form a primary isolation for the elastic lock core body by providing a protective panel in front of the elastic lock core body, and a secondary seal is formed by providing a local corresponding gasket in front of the lock eye, and a back-adhesive sealing ring is provided on the back of the elastic lock core body to further form a sealing protection. Compared with the traditional locking method, the lock core has a triple protection structure, which not only effectively protects the internal parts from rain and salt spray erosion, but also prevents particles or other debris from entering the lock core, thereby extending its service life and ensuring that the door lock can be used normally;
[0013] 2. The elastic lock core with a three-proof structure is provided with a lock buckle under the protective panel, which can be easily closed by the engagement of the latch, and a pair of torsion springs are provided on the back of the protective panel, so that it can not only pop out automatically after opening, but also form an angle support to open the internal door lock, which is very convenient to use.

DETAILED DESCRIPTION
[0019] See also Figure 1-3 The utility model provides a technical solution: an elastic lock core with a three-proof structure, including an elastic lock core body 1, a connecting panel 2, a keyhole 3, a first groove 4, an auxiliary component 5, a protective panel 6, an opening and closing component 7, and a second groove 8; a connecting panel 2 is fixed to the front of the elastic lock core body 1, a keyhole 3 is arranged in the front of the elastic lock core body 1, a first groove 4 is opened in the front of the elastic lock core body 1, an auxiliary component 5 is arranged on the inner side of the first groove 4, a protective panel 6 is connected to the front of the auxiliary component 5, an opening and closing component 7 is connected to the front of the elastic lock core body 1, and a second groove 8 is opened in the front of the elastic lock core body 1. By arranging the protective panel 6 in front of the elastic lock core body 1, the elastic lock core body 1 can be initially isolated, and by arranging a partially corresponding gasket 505 in front of the keyhole 3, a second Secondary seal, and by arranging a back-adhesive sealing ring 9 on the back of the elastic lock core body 1, further sealing protection is formed. Compared with the traditional locking method, the lock core has a triple protection structure. The auxiliary component 5 includes a center column 501 and a sleeve 502. The center column 501 is fixed on the inner side of the first groove 4. The center column 501 is rotatably connected to the sleeve 502. The sleeve 502 is fixed on the back of the protective panel 6. The sleeve 502 rotates in the center column 501 to allow the protective panel 6 to rotate at an angle. The auxiliary component 5 also includes a torsion spring 503. The surface of the center column 501 is connected to the torsion spring 503. The torsion spring 503 is symmetrically arranged about the center line of the center column 501. Through the deformation of the torsion spring 503, the protective panel 6 can automatically pop out and form a support after being opened to facilitate unlocking.
[0020] See also Figure 3-4In this embodiment, the auxiliary component 5 also includes an auxiliary lock 504 and a gasket 505. The auxiliary lock 504 is arranged on the back of the protective panel 6. The back of the auxiliary lock 504 is connected to the gasket 505. The gasket 505 is made of rubber. After the protective panel 6 is closed, the gasket 505 is pressed against the front of the keyhole 3 to accurately achieve partial sealing to prevent moisture from penetrating. The opening and closing component 7 includes a lock buckle 701, a socket 702, and a latch 703. The front of the elastic lock core body 1 is connected to the lock buckle 701. A socket 702 is provided at the upper end, and the socket 702 is engaged with a latch 703. The latch 703 is arranged at the lower end of the protective panel 6. By opening the auxiliary lock 504, the latch 703 can be inserted into the socket 702, thereby achieving a locking effect. A sealing ring 9 is connected to the back of the elastic lock core body 1. The sealing ring 9 is made of rubber material. By providing a back-adhesive sealing ring 9 at the joint between the door lock and the box body, the problem of uneven sealing due to the traditional use of silicone pads and easy deformation during assembly can be prevented, thereby effectively improving the sealing effect.
[0021] When using the elastic lock core with a three-proof structure of the present technical solution, first press the protective panel 6 downward. Through the deformation of the torsion spring 503 and the rotation of the sleeve 502 on the central column 501, the protective panel 6 can be adjusted in angle until the back of the gasket 505 contacts the front surface of the keyhole 3. Then, the auxiliary lock 504 is started with a medicine key to drive the pin 703 to be inserted into the socket 702, thereby fixing the protective panel 6 and the lock buckle 701 together to form a protective effect.
[0022] Through the above steps, the auxiliary component 5 is first used to facilitate changing the angle of the protective panel 6, and then the protective panel 6 can be locked through the opening and closing component 7, and the gasket 505 and the sealing ring 9 can be used to enhance the sealing to protect the elastic lock core body 1.
