The right side of the closure auxiliary connection has a deflection storage groove, and the left side of the inner wall of the deflection storage groove is movably connected to the opposite ends of two auxiliary buckles through two rotation reset structures. The right side of the closure auxiliary connection is fixedly connected to the left side of the locating guide block.

[0007] As a further aspect of the present invention: the upper arc positioning groove is located above the corresponding lower arc positioning component, and the lower arc positioning groove is located below the corresponding upper arc positioning component.

[0008] As a further aspect of the present invention: the position of the closing auxiliary connecting groove is consistent with that of the corresponding closing auxiliary connecting member, the inner wall of the alignment guide groove is funnel-shaped, and the inner wall of the alignment guide groove matches the surface shape of the alignment guide block.

[0009] As a further aspect of the present invention: there are three positioning auxiliary blocks and three positioning auxiliary slots, the positioning auxiliary blocks are fitted with the inner walls of the corresponding positioning auxiliary slots, and the inner walls of the positioning auxiliary slots are provided with rubber blocks.

[0010] As a further aspect of the present invention: two pre-installation holes are provided on the right side of the closing auxiliary connector, and screws provided in the pre-installation holes are fixedly connected to the right side of the prefabricated floor base.

[0013] As a further aspect of the present invention: the curvature of the surfaces of the lower arc sliding member and the upper arc sliding member are consistent with the curvature of the inner walls of the lower arc sliding groove and the upper arc sliding groove, respectively.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This prefabricated flooring, which is easy to assemble, uses upper and lower arc-shaped sliding components, upper and lower arc-shaped sliding grooves, positioning auxiliary blocks, and positioning auxiliary grooves. During installation, a certain tilt angle is maintained. Then, the prefabricated flooring base is tilted at a certain angle so that the lower and upper arc-shaped sliding components correspond to the upper and lower arc-shaped sliding grooves, respectively. As they move closer together, the lower surface of the upper part of the groove is in contact with the upper surface of the lower arc-shaped sliding component, maintaining a certain curvature as they slide into the corresponding upper and lower arc-shaped sliding grooves. When the upper and lower arc-shaped sliding components slide into their corresponding upper and lower arc-shaped sliding grooves, the two prefabricated flooring bases remain tightly fitted. This method is simple to install. Under the interaction between the two arcs and the help of gravity, there is no lateral displacement. The structure is stable and the installation is more convenient.

[0017] 2. This easily assembled prefabricated flooring utilizes a combination of auxiliary connectors, auxiliary clips, deflection storage grooves, positioning pins, return torsion springs, and auxiliary slots. The positioning auxiliary block fits tightly into the positioning auxiliary groove. As the prefabricated flooring base moves downwards, the two auxiliary connectors on its right side move synchronously, entering the auxiliary connector groove. Subsequently, under the action of the alignment guide block and alignment guide groove, the auxiliary connector moves stably upwards within the groove. Simultaneously, the two auxiliary clips on the inner wall of the deflection storage groove rotate on the surface of the positioning pin under the action of the inner wall of the groove. At the same time, the return torsion spring is turned until the auxiliary connector is fully inside the groove. The auxiliary clips then pop out from the deflection storage groove under the action of the return torsion spring and enter the auxiliary slot to remain locked. This method maintains the fixation of the side of the prefabricated flooring base, further improving the stability of the installation structure.

[0018] 3. This easy-to-assemble prefabricated flooring, with its alignment guide blocks, alignment guide grooves, and horizontal arc-shaped protrusions and concave ribs, allows for easy installation. One prefabricated flooring base is placed, followed by placing the front of another prefabricated flooring base against the back of the first. The horizontal arc-shaped protrusions and concave ribs of the two bases are then aligned at a certain angle, providing excellent installation and positioning assistance. This ensures a tight fit and better sealing. When the alignment guide blocks and alignment guide grooves are engaged, they maintain stable placement of the closing auxiliary connectors and closing auxiliary connector grooves, resulting in more accurate installation.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-5 As shown, the present invention provides a technical solution: a tightly assembled and locked prefabricated floor, comprising a prefabricated floor base 1, two closing auxiliary connectors 2 provided on the right side of the prefabricated floor base 1, the front of the prefabricated floor base 1 fixedly connected to the back of two lower arc sliding members 3, the back of the prefabricated floor base 1 fixedly connected to the front of two upper arc sliding members 4, two lower arc sliding grooves 6 formed on the front of the prefabricated floor base 1, two upper arc sliding grooves 5 formed on the back of the prefabricated floor base 1, and two closing auxiliary connection grooves 9 formed on the left side of the prefabricated floor base 1. Auxiliary slots 10 are provided on both the front and back of the inner wall of the auxiliary connecting groove 9. A aligning guide groove 11 is provided on the right side of the inner wall of the closing auxiliary connecting groove 9. The front of the prefabricated floor base 1 is fixedly connected to the back of several positioning auxiliary blocks 7. Several positioning auxiliary grooves 8 are provided on the back of the prefabricated floor base 1. A deflection storage groove 14 is provided on the right side of the closing auxiliary connector 2. The left side of the inner wall of the deflection storage groove 14 is movably connected to the opposite end of two auxiliary buckles 15 through two rotation reset structures 16. The right side of the closing auxiliary connector 2 is fixedly connected to the left side of the aligning guide block 17.

[0027] Specifically, such as Figure 1 , 2As shown in Figure 3, the upper arc sliding groove 5 is located above the corresponding lower arc sliding component 3, and the lower arc sliding groove 6 is located below the corresponding upper arc sliding component 4. There are three positioning auxiliary blocks 7 and three positioning auxiliary grooves 8. The positioning auxiliary blocks 7 are in contact with the inner wall of the corresponding positioning auxiliary groove 8. A rubber block is provided on the inner wall of the positioning auxiliary groove 8. The upper surface of the auxiliary buckle 15 is arc-shaped. The front of the prefabricated floor base 1 is provided with a horizontal arc-shaped protrusion 12, and the back of the prefabricated floor base 1 is provided with a horizontal arc-shaped concave rib 13. The surface of the horizontal arc-shaped protrusion rib 12 and the inner wall curvature of the horizontal arc-shaped concave rib 13 are consistent. The curvature of the surfaces of the lower arc sliding component 3 and the upper arc sliding component 4 are consistent with the inner wall curvature of the lower arc sliding groove 6 and the upper arc sliding groove 5, respectively. By setting the upper arc sliding groove 5, the upper arc sliding groove 5 can maintain a stable fit with the upper arc sliding component 4 during use. Simultaneously, the cooperation between the upper arc sliding component 3 and the lower arc sliding groove 6 can maintain its... Lateral stability and fixation are achieved through the placement of a positioning auxiliary block 7. The positioning auxiliary block 7 and the positioning auxiliary groove 8 work together to maintain a stable fit, ensuring a secure connection between the upper arc sliding groove 5 and the upper arc sliding component 4. This prevents misalignment during use. A rubber block keeps the positioning auxiliary block 7 within the positioning auxiliary groove 8, ensuring a stable fit. A horizontal arc-shaped protrusion 12 and a horizontal arc-shaped concave rib 13 work together to maintain a stable position during deflection and improve the closure of the upper surface, preventing loose fit. A lower arc sliding component 3, when working with the upper arc sliding component 4, provides excellent limiting and support due to their mutual curvature, resulting in greater stability during use.

[0028] Specifically, such as Figure 4 and 5As shown, the closing auxiliary connection groove 9 is positioned consistent with the corresponding closing auxiliary connection piece 2. The inner wall of the alignment guide groove 11 is funnel-shaped and matches the surface shape of the alignment guide block 17. Two pre-installation holes 18 are provided on the right side of the closing auxiliary connection piece 2. Screws installed in the pre-installation holes 18 are fixedly connected to the right side of the prefabricated floor base 1. The rotation reset structure 16 includes a positioning pin 161, a reset torsion spring 162, and a limit block 163. The positioning pin 161 connects one end of the auxiliary buckle 15 with the deflection... The left side of the inner wall of the storage slot 14 is movably connected, and the right end of the positioning pin 161 is fixedly connected to the left side of the limiting block 163. A reset torsion spring 162 is sleeved on the surface of the positioning pin 161. The two ends of the reset torsion spring 162 are fixedly connected to the right side of the auxiliary buckle 15 and the left side of the limiting block 163, respectively. By setting a closing auxiliary connecting groove 9, the size of the closing auxiliary connecting groove 9 is the same as the size of the closing auxiliary connecting piece 2. They can slide against each other during use and play a fixing role in cooperation with the closing auxiliary connecting piece 2. A locating guide groove 11 is provided, the lower surface of which is funnel-shaped. When sliding between the locating guide block 17 and the locating guide block 17, it can guide the locating guide block 17. At the same time, the locating guide block 17 and the locating guide groove 11 can fit together, which can assist in the sliding between the closing auxiliary connector 2 and the closing auxiliary connector groove 9, achieving a good connection effect. By providing a pre-installation hole 18, the closing auxiliary connector 2 can be easily installed on the surface of the prefabricated floor base 1 during use. At the same time, it can protect the screws during use. By providing a rotary reset structure 16, the positioning pin 161 of the rotary reset structure 16 can keep the auxiliary buckle 15 rotating stably on its surface. At the same time, under the action of the reset torsion spring 162, it maintains a reset elastic force. When rotating, the reset torsion spring 162 can maintain a torsional force under the action of the limiting block 163. At the same time, the limiting block 163 can effectively limit the reset torsion spring 162, so that the reset torsion spring 162 will not slip off the surface of the positioning pin 161 during use.

[0029] The working principle of this invention is as follows:

[0030] S1. During installation, first place one prefabricated floor base 1, then place the front of another prefabricated floor base 1 opposite the back of the first prefabricated floor base 1, and fit the horizontal arc-shaped protrusions 12 and horizontal arc-shaped concave ribs 13 of the two prefabricated floor bases 1 together, maintaining a certain angle of inclination. Then, place the rear prefabricated floor base 1 at a certain angle so that its lower arc sliding member 3 and upper arc sliding member 4 correspond to the upper arc sliding groove 5 and lower arc sliding groove 6 respectively.

[0031] S2, so that the lower surface of the upper part groove is in contact with the upper surface of the lower arc sliding part 3 as they move closer to each other, so that they slide into the corresponding upper arc sliding groove 5 and lower arc sliding groove 6 with a certain curvature. When the upper arc sliding part 4 and the lower arc sliding part 3 slide into the corresponding upper arc sliding groove 5 and lower arc sliding groove 6 respectively, the two prefabricated floor bases 1 are in close contact. At the same time, the positioning auxiliary block 7 enters the positioning auxiliary groove 8 and is in close contact. As the prefabricated floor base 1 moves downward, the two closing auxiliary connectors 2 on its right side move synchronously.

[0032] S3. When the closing auxiliary connector 2 moves, it enters the closing auxiliary connector groove 9. Then, under the action of the alignment guide block 17 and the alignment guide groove 11, the closing auxiliary connector 2 moves steadily upward in the closing auxiliary connector groove 9. At the same time, the two auxiliary buckles 15 on the inner wall of the deflection storage groove 14 of the closing auxiliary connector 2 rotate on the surface of the positioning pin 161 under the action of the inner wall of the closing auxiliary connector groove 9. At the same time, the reset torsion spring 162 is turned until the closing auxiliary connector 2 is completely entered into the closing auxiliary connector groove 9. Under the action of the reset torsion spring 162, the auxiliary buckles 15 pop out from the deflection storage groove 14 and enter the auxiliary buckle groove 10 to be locked. Then, repeat this step in sequence for installation.
