[0024] A composite floor slab connection and fixing device includes a floor slab body 1. A connecting component 2 is symmetrically arranged on the left side of the base surface of the floor slab body 1. A fixing seat 3 is symmetrically arranged on the right side of the base surface of the floor slab body 1. Fixing grooves 4 are symmetrically opened on the front and back sides inside the fixing seat 3. Limiting rods 5 are symmetrically arranged on the front and back of the left side of the floor slab body 1. Limiting holes 6 are symmetrically opened on the front and back of the right side of the floor slab body 1.

[0025] The connecting assembly 2 includes a connecting seat 201. A threaded rod 202 is rotatably disposed in the middle of the connecting seat 201. An adjusting sleeve 203 is threaded on the outer wall of the threaded rod 202. A first rotating rod 204 is disposed on the front side of the adjusting sleeve 203, and a second rotating rod 205 is disposed on the back side of the adjusting sleeve 203. A first adjusting groove 206 is opened on the front side of the connecting seat 201, and a second adjusting groove 207 is opened on the back side of the connecting seat 201. A first fixing rod 208 is slidably disposed inside the first adjusting groove 206, and a second fixing rod 209 is slidably disposed inside the second adjusting groove 207. A first connecting rod 210 is rotatably disposed between the rear end of the first fixing rod 208 and the first rotating rod 204, and a second connecting rod 211 is rotatably disposed between the front end of the second fixing rod 209 and the second rotating rod 205. An adjusting knob 212 is rotatably disposed on the base surface of the connecting seat 201.

[0026] The bottom of the connecting seat 201 is fixedly connected to the left side of the base surface of the floor slab body 1. The outer wall of the adjusting knob 212 is evenly provided with anti-slip texture to increase the friction with the hand and make it rotate more stably. The adjusting knob 212 is connected to the upper end of the threaded rod 202 through the connecting shaft. The fixing seat 3 is arranged in a "U" shape and is adapted to the connecting seat 201. The first fixing rod 208 and the second fixing rod 209 are respectively adapted to the fixing groove 4, the first adjusting groove 206, and the second adjusting groove 207, so that the first fixing rod 208 and the second fixing rod 209 can enter the interior of the fixing groove 4, and the first fixing rod 208 and the second fixing rod 209 can slide stably inside the first adjusting groove 206 and the second adjusting groove 207, respectively. The limiting hole 6 is adapted to the limiting rod 5. This allows the limiting rod 5 to enter the limiting hole 6. By setting the connecting component 2 on the composite floor slab connection and fixing device, when connecting, the limiting rod 5 on the floor slab body 1 is inserted into the upper limiting hole 6 of the adjacent floor slab body 1. At this time, the fixing seat 3 is engaged with the connecting seat 201 on the adjacent floor slab body 1. Rotating the adjusting knob 212 can drive the threaded rod 202 to rotate.

The connection is relatively convenient, the overall device structure is simple, the operation is convenient and the practicality is higher.

[0027] The working process of this utility model is as follows: When using the composite floor slab connection and fixing device, a connecting component 2 is set on the composite floor slab connection and fixing device. During connection, the limiting rod 5 on the floor slab body 1 is inserted into the upper limit hole 6 of the adjacent floor slab body 1. At this time, the fixing seat 3 is engaged with the connecting seat 201 on the adjacent floor slab body 1. Then, the adjusting knob 212 is rotated. When the adjusting knob 212 rotates, it drives the threaded rod 202 to rotate. Since the adjusting sleeve 203 is threadedly connected to the threaded rod 202, the threaded rod 202 drives the adjusting sleeve 203 to move when it rotates. When the adjusting sleeve 203 moves, it can... The first rotating rod 204 and the second rotating rod 205 are moved respectively. The first connecting rod 210 and the second connecting rod 211 can move the first fixed rod 208 and the second fixed rod 209 respectively. When the first fixed rod 208 and the second fixed rod 209 move, they respectively drive the first connecting rod 210 and the second connecting rod 211 to rotate. When the first connecting rod 210 and the second connecting rod 211 rotate, they respectively drive the first fixed rod 208 and the second fixed rod 209 to move. When the first fixed rod 208 and the second fixed rod 210 move into the inside of the fixing groove 4, they can be connected and fixed.
