[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides a technical solution: a push-type wooden floor connection structure, including a floor body 1, both ends of the bottom of the floor body 1 are connected with connection keys 2, the floor body 1 includes a horizontal plate 8, both ends of the bottom of the horizontal plate 8 are provided with L-shaped grooves 9, and the top of the inner wall of the L-shaped groove 9 is integrally provided with a clamping block 10, the side wall of the L-shaped groove 9 is integrally connected with a protrusion 11, and the area between the clamping block 10 and the protrusion 11 forms a groove 12.

[0018] It should be noted that the connection between the two vertical surfaces of the L-shaped groove 9 is an arc-shaped structure, and the end of the clamping block 10 is slightly inclined toward the outside, so that the position of the clamping block 10 is more stable after connection.

[0019] The connecting key 2 includes a base plate 6, a boss 3 is integrally provided on the top of the base plate 6, a protrusion 4 is symmetrically integrally provided on the top of the base plate 6 and located outside the boss 3, a slot 5 is formed between the protrusion 4 and the boss 3, a connecting groove 7 is formed between the top of the base plate 6 and the protrusion 4, the protrusion 4 is snapped into the groove 12, the block 10 is snapped into the slot 5, and the protrusion 11 is snapped into the connecting groove 7.

[0020] It should be noted that, during the process of connecting the floor body 1 and the connecting key 2, the connecting key 2 is pressed vertically from top to bottom to connect, so that the protrusion 4 on the connecting key 2 corresponds to the groove 12 on the floor body 1, the block 10 on the floor body 1 corresponds to the groove 5, and the protrusion 11 on the floor body 1 corresponds to the connecting groove 7. As the depth of the pressed connection increases, the protrusion 4 on the side of the connecting key 2 cuts into the groove 12 of the floor body 1 to form a snap-fitting position, the block 10 on the floor body 1 corresponds to the groove 5, and the protrusion 11 corresponds to the inside of the connecting groove 7. When disassembling, the floor body 1 can be disassembled by using a suction cup lifting device.
