One side of the bottom box 12 has a bottom box opening, and the two card seats 13 are respectively fixed at both ends of the bottom box opening, so that a lock case opening is formed in the middle of the bottom box opening. The handle 2 is a long strip-shaped structure corresponding to the lock case 1. The positioning buckle 4 and the locking buckle 3 are respectively arranged corresponding to the two card seats 13. One of the card seats 13 has a card seat perforation 130 corresponding to the lock head 31 of the locking buckle 3. In the above structure, the lock case 1 is assembled by the bottom box 12 and the card seats 13, which also facilitates the convenient installation of the hidden push-pull door lock mechanism of the refrigerator in the lock case 1, and has the characteristics of simple structure and easy assembly.
[0035] Further, the two end side walls of the bottom box 12 are provided with clamping grooves 121, and the clamping seat 13 is correspondingly provided with clamping heads 131 corresponding to the clamping grooves 121. The clamping heads 131 are inserted into the clamping grooves 121 of the bottom box 12 to connect the clamping seat 13 with the bottom box 12. In the above structure, through the mutual cooperation of the clamping heads 131 and the clamping grooves 121, the rapid connection between the clamping seat 13 and the bottom box 12 is realized.
[0036] Reference Figures 1 to 3 , a refrigerator door lock structure installation structure, which includes a box body 5 and a door body 6. The above-mentioned refrigerator hidden push-pull door lock mechanism is installed between the door body 6 and the box body 5. The refrigerator hidden push-pull door lock mechanism is installed inside one side surface of the door body 6. When installing, the front surface of the handle 2 can be kept flush with the side surface of the door body 6 as much as possible. A lock seat 7 is installed on the front surface of the box body 5.

When closing the door, the user can press the handle 2 from the front surface of the handle 2 again to make the lock head 31 retract into the inner cavity 10 of the lock shell. After closing the door body 6 and releasing the hand, the lock head 31 automatically pops out and inserts into the lock hole 71 to make the refrigerator hidden push-pull door lock mechanism restore to the locked state, realizing the locking of the door body 6.
[0040] It should be noted that the end of the lock head 31 can also be set as a beveled lock tongue structure, so that the lock head 31 can automatically retract after being impacted. When closing the door, the user only needs to gently push the door body 6. When the lock head 31 hits the lock seat 7, it will automatically retract and then automatically pop into the lock hole 71 to lock the door body 6.
[0041] The refrigerator of this embodiment can also adopt an upper and lower double-door structure. Specifically: a horizontal partition 50 is provided in the middle of the box body 5 to divide the box body 5 into upper and lower 2 refrigeration chambers. The door body 6 includes 2 arranged up and down along the front of the box body 5. The lock seat 7 has a vertical locking portion 72 and a seat portion 73 horizontally connected to the middle of the locking portion 72 at one end. The seat portion 73 has a seat mounting hole and is connected to the front of the horizontal partition 50 by a bolt 731. The locking portion 72 faces the side of the door body 6. The lock holes 71 of the lock seat 7 include 2 and are symmetrically arranged at both ends of the locking portion 72. The lock heads 31 of the hidden push-pull type door lock mechanism of the upper and lower 2 door bodies 6 of the refrigerator face the 2 lock holes 71 of the lock seat 7.
[0042] For a refrigerator with an upper and lower double-door structure, the lock heads 31 on the upper door and the lock heads 31 on the lower door are arranged close to each other, so that the lock holes 71 of the lock seat 7 can be directly opposite to the lock heads 31 very conveniently, thereby ensuring the smoothness of unlocking and locking.
