[0007] A flat head part;

[0008] A screw rod is fixedly connected to the flat head part;

[0009] The bottom of the flat head part is provided with a groove.

[0010] Preferably, the thickness of the flat head part is 0.9-1.1mm.

[0011] Further, the groove depth of the groove is 0.3-0.5mm.

[0012] Preferably, an assembly groove is formed in the flat head part.

[0013] Further, the assembly groove is a Chinese character slot.

[0014] Preferably, a transition angle is formed in the flat head part.

[0015] Further, the radius of the transition angle is 0.4mm.

[0016] Further, the groove is a circular groove, and the groove diameter is 10.1-10.3mm.

[0017] Compared with the prior art, the utility model provides a flat head screw, which has the following beneficial effects:

[0018] The part not involved in the device is the same as or can be realized by the prior art, the recess on the flat head part is designed to lock the screw into the wood plate, effectively solves the problem of uneven locking caused by the wood tip against the screw, improves the flatness and stability of the installation; meanwhile, the thickness of the flat head part in the application is 0.9-1.1mm, when applied to the cabinet door rebounder, the door gap thickness can be smaller, not only plays a role in flatness and beauty, but also effectively prevents insects, improves the practicability and beauty of the product.

[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Embodiment 1:

[0025] Referring to Figures 1-3 , a flat head screw comprises:

[0026] a flat head part 1;

[0027] a screw rod 2 fixedly connected to the flat head part 1;

[0028] The flat head part 1 is provided with a recess 101 at the bottom.

[0029] The thickness of the flat head part 1 is 0.9-1.1mm.

[0030] The groove depth of the recess 101 is 0.3-0.5mm.

[0031] During installation, first align the screws with the pre-drilled mounting holes on the cabinet door rebound device and the wooden board. Then, use the appropriate screwdriver to screw the screws into the cross-shaped mounting groove 103. Since the flat head 1 has a groove 101 at the bottom, the wooden dot can enter the groove 101 during the screw tightening process, preventing it from pressing against the screw and allowing the screw to be smoothly locked flat. At the same time, the flat head 1 is relatively thin, which can effectively reduce the thickness of the door gap, achieving a flat and beautiful appearance and insect-proof effect after the cabinet door is installed.

[0032] An assembly slot 103 is provided on the flat head 1.

[0033] Assembly slot 103 is a star-shaped groove.

[0034] A transition angle 102 is provided on the flat head 1.

[0035] The radius of the transition angle 102 is 0.4 mm.

[0036] The groove 101 is a circular groove with a diameter of 10.1-10.3 mm.

[0037] This utility model, through the design of the groove 101 on the flat head 1, allows the screw to be locked flat after being inserted into the wooden board, effectively solving the problem of uneven locking caused by the wooden tip pressing against the screw, and improving the flatness and stability of the installation; at the same time, the flat head 1 in this application is designed with a thickness of 0.9-1.1mm, which can make the door gap thickness smaller when applied to the cabinet door rebound device, not only playing a flat and beautiful role, but also effectively preventing insects, improving the practicality and aesthetics of the product.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
