DETAILED DESCRIPTION

[0019] 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.

[0020] Refer to the instruction manual Figure 1-3 ,like Figure 1 As shown, a detachable prefabricated floor slab snap-on connection structure of an embodiment of the utility model comprises a transverse steel frame 1, a vertical steel frame 2 is fixedly installed on one side of the transverse steel frame 1, and a prefabricated floor slab 3 is inserted into the inner side of the transverse steel frame 1. Figure 2 As shown, a block 4 is slidably connected inside the transverse steel frame 1, and the block 4 is inserted into the interior of the prefabricated floor 3. A limiting rod 5 is fixedly installed on one side of the block 4. A positioning plate 7 is slidably connected inside the transverse steel frame 1. A first spring 6 is provided on one side of the positioning plate 7. The first spring 6 is fixedly installed on one side of the block 4. The limiting rod 5 is slidably connected inside the positioning plate 7. A transmission member 8 is slidably connected inside the prefabricated floor 3, and a push plate 9 is fixedly installed on one end of the transmission member 8. By setting the push plate 9, the contact area with the block 4 is increased, so that the block 4 can push the transmission member 8 to slide. The push plate 9 is slidably connected inside the prefabricated floor 3, as shown in FIG. Figure 3 As shown, a second spring 10 is provided on one side of the transmission member 8. The second spring 10 is fixedly installed inside the prefabricated floor slab 3. A bevel transmission rod 11 is slidably connected inside the prefabricated floor slab 3.

[0021] It should be noted that, when the prefabricated floor 3 needs to be fixed, the prefabricated floor 3 is placed on the inner side of multiple horizontal steel frames 1 and vertical steel frames 2. At this time, the bevel groove opened at the bottom of the prefabricated floor 3 contacts the block 4, and the prefabricated floor 3 is pressed flat to make it drop. When the prefabricated floor 3 continues to apply pressure to the block 4, the block 4 will gradually slide toward the inside of the horizontal steel frame 1, and the first spring 6 will contract. After the prefabricated floor 3 drops to the lowest point, the block 4 coincides with the fixing hole on one side of the prefabricated floor 3, and the block 4 loses its limit. Under the tensile action of the limit rod 5, the block 4 is inserted into the inside of the prefabricated floor 3. , thereby fixing the prefabricated floor 3. At the same time, when the block 4 is engaged in the fixing hole of the prefabricated floor 3, the push plate 9 will be pushed, so that the transmission member 8 slides to one side. When the transmission member 8 slides, the second spring 10 will contract and at the same time, the bevel transmission rod 11 will slide to one side by contacting the bevel of the bevel transmission rod 11. At the same time, the third spring 13 will contract, so that the fixing pin 12 will be inserted into the interior of the vertical steel frame 2, thereby further fixing the prefabricated floor 3, thereby improving the stability of the prefabricated floor 3, and at the same time, the time required for installing the prefabricated floor 3 is reduced by the snap connection, thereby improving the efficiency of installing the prefabricated floor 3.

[0022] Further, such as Figure 3 As shown, a fixing pin 12 is fixedly installed at one end of the bevel transmission rod 11, and the fixing pin 12 is inserted into the interior of the vertical steel frame 2. The fixing pin 12 is slidably connected to the interior of the prefabricated floor 3. A third spring 13 is provided at one end of the bevel transmission rod 11, and the third spring 13 is fixedly installed inside the prefabricated floor 3. Figure 2 As shown, the interior of the vertical steel frame 2 is rotatably connected with a double-headed screw 14, the outer side of the double-headed screw 14 is threadedly connected with an internal thread block 15, the internal thread block 15 is slidably connected to the interior of the vertical steel frame 2, the positioning plate 7 is fixedly installed on one side of the internal thread block 15, one end of the double-headed screw 14 is fixedly installed with a first bevel gear 16, the outer side of the first bevel gear 16 is meshed with a second bevel gear 17, the top of the second bevel gear 17 is fixedly installed with an extension rod 18, the extension rod 18 is rotatably connected to the interior of the vertical steel frame 2, and the top of the extension rod 18 is fixedly installed with a turning handle 19.

[0023] It should be noted that, when the prefabricated floor 3 needs to be disassembled, the extension rod 18 drives the second bevel gear 17 to rotate by turning the handle 19, and then the second bevel gear 17 is meshed with the first bevel gear 16 to cause the double-headed screw 14 to rotate. Since the internal thread block 15 is threadedly connected to the double-headed screw 14, when the double-headed screw 14 rotates, the internal thread block 15 slides to one side, thereby driving the positioning plate 7 to slide to one side and causing the block 4 to move synchronously, thereby separating from the prefabricated floor 3. The rod 14 is a double-headed screw rod, which will cause the block 4 on the other side to slide synchronously while rotating, thereby simultaneously releasing the clamping and fixing of multiple blocks 4 to the prefabricated floor slab 3. At the same time, since the push plate 9 loses the limit of the block 4, the second spring 10 is stretched to reset the transmission member 8. At the same time, the bevel transmission rod 11 loses the limit of the transmission member 8 and the fixing pin 12 is reset under the stretching action of the third spring 13. At this time, the prefabricated floor slab 3 can be disassembled, thereby achieving the purpose of quickly disassembling the prefabricated floor slab 3, thereby improving the efficiency of disassembling the prefabricated floor slab 3.
