[0030] See also Figure 1-Figure 7 The present invention provides the following technical solutions: a simple automatic rebound door lock, comprising a door lock housing 1, a door lock side cover 2 is installed on one side of the door lock housing 1, and a switch handle 3 is installed in the middle of one side of the door lock side cover 2;

[0031] Example 1: Figures 1-4 As shown, the device utilizes the door core mechanism to enable the lock tongue 8 to automatically rebound, specifically as follows:

[0032] An automatic rebound door core mechanism is installed in the cavity of the door lock shell 1. The door core mechanism includes a door lock body 4, one end of the door lock body 4 is installed at one end in the cavity of the door lock shell 1, a safety bolt 5 is provided below one end of the door lock body 4, and the safety bolt 5 is located below the outer side of the door lock shell 1, and a rebound chamber 6 is opened above one end of the door lock body 4, and auxiliary slides 7 are provided in the middle of the top and bottom of the rebound chamber 6. One end of the rebound chamber 6 is stuck in one end of a lock tongue 8, and the middle of the top and bottom of the lock tongue 8 are provided with auxiliary slides 10, and the auxiliary slides 7 are correspondingly stuck in the auxiliary slides 10. The two ends of the top of the rebound chamber 6 are correspondingly provided with moving grooves 11, and a recovery chamber 12 is opened at one end of the rebound chamber 6. One end of the lock tongue 8 is connected to one end of the assembly column 13, and the other end of the assembly column 13 is inserted into one end of the recovery chamber 12;

[0033] A rebound spring 14 is sleeved on the outside of the assembly column 13, and an assembly frame 15 is installed at both ends of one side of the top of the door lock body 4, and the two assembly frames 15 are respectively located above the two moving grooves 11, and an assembly rod 16 is installed between the two ends of the cavity of the two assembly frames 15. Auxiliary slides 17 are installed at both ends of one side of the top of the lock tongue 8, and the tops of the two auxiliary slides 17 pass through the moving grooves 11 respectively, and the tops of the two auxiliary slides 17 are respectively sleeved on one end of the two assembly rods 16, and the other ends of the two assembly rods 16 are sleeved with auxiliary springs 18, and the auxiliary springs 18 are located between one end of the cavity of the assembly frame 15 and the top of one side of the auxiliary slide 17;

[0034] By utilizing the cooperation of the auxiliary slide bar 7 and the auxiliary slide groove 10, the direction of movement of the lock tongue 8 such as rebound is limited to prevent the lock tongue 8 from deviating during the movement, causing the lock tongue 8 to be stuck and unable to work. The assembly frame 15 is used to assemble parts such as the assembly rod 16. The auxiliary spring 18 can assist the rebound spring 14 in pushing the lock tongue 8, so that the lock tongue 8 can rebound faster and more reliably.

[0035] Example 2: Figure 5-Figure 6 As shown, the device can disinfect the switch handle 3 after use by using a disinfection mechanism, as follows:

[0036] A disinfection mechanism for disinfecting the switch handle 3 is provided above one side of the door lock side cover 2. The disinfection mechanism includes a mounting shell 9, which is mounted above one side of the door lock side cover 2. A removal port 19 is provided below one side of the mounting shell 9. A moving motor 20 is installed above one end of the cavity of the mounting shell 9. A moving screw rod 21 is installed between one end of the moving motor 20 and the top of the other end of the cavity of the mounting shell 9. A moving slider 22 is sleeved on one end of the outer side of the moving screw rod 21. The bottom of the moving slider 22 is connected to one end of the top of the ultraviolet germicidal lamp 23, and the ultraviolet germicidal lamp 23 is located below the cavity of the mounting shell 9 and on one side of the removal port 19.
