[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A combined screw structure with a waterproof structure, including a screw body, on which a pressing plate is slidably sleeved, the upper end of the pressing plate is fixedly connected with a waterproof sleeve, the upper end of the waterproof sleeve is designed with an opening, a fixing block is fixedly connected to the side wall of the waterproof sleeve, a groove is opened on the side wall of the fixing block, a rotating rod is rotatably connected between the inner walls at both ends of the groove, a rotating plate is fixedly sleeved on the rotating rod, and a waterproof cover plate matched with the opening is fixedly connected to the end of the rotating plate.

[0007] Preferably, torsion springs are arranged at the rotational connections between both ends of the rotating rod and the groove.

[0008] Preferably, a nut is fixedly connected to the upper end of the screw body, and a cross slot is opened on the upper end of the nut.

[0009] Preferably, a rotating ring is rotatably connected to the lower end of the nut, and the rotating ring and the pressing plate are elastically connected by a spring.

[0010] Preferably, a thread groove is opened on the outer wall of the screw body.

[0011] Preferably, a waterproof pad is provided at the upper end of the waterproof sleeve, and the material of the waterproof pad is rubber.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By providing a waterproof sleeve and a waterproof cover plate, when the screw body is tightened, the waterproof cover plate is rotated so that the waterproof cover plate is in the vertical direction, and the pressing plate is pressed upward, thereby pushing the waterproof sleeve upward, so that the waterproof sleeve covers the nut. After the tightening is completed, the waterproof cover plate is loosened, and the waterproof cover plate rotates to the horizontal direction under the action of the torsion spring to cover the opening, so as to close the opening, wrap the nut in the waterproof sleeve, and avoid water erosion of the nut, resulting in difficult disassembly.

[0014] 2. By providing a pressing plate and a spring, when the screw body is tightened, the pressing plate below the screw body contacts the surface of the workpiece. When the locking is completed, the spring is compressed, and under the elastic force of the spring, the pressing plate presses against the surface of the workpiece, forming a reaction force on the screw body, so as to achieve the effect of pressing the screw body tightly, and can avoid loosening of the screw body, improving the practicability of the device.
