It can be imagined that the screw buckle for preventing shaking also includes some other functional modules, such as rivet punches, etc., which are well-known technologies to those skilled in the art and will not be elaborated here.

[0021] The surface buckle 10 includes a surface cover 11 and a cover column plate 12 buckled to the surface cover 11. The surface buckle 10 is used to assist in fixing the female buckle 20 so that the female buckle 20 is riveted to the surface buckle 10. The cover column plate 12 is provided with a hollow column and an annular clearance groove. The surface buckle 10 is a general technology and will not be elaborated here.

[0022] The female buckle 20 includes a female buckle main body 21, an installation groove 22 provided in the female buckle main body 21, a spring groove 23 provided on the side of the installation groove 22, a spring 24 provided in the spring groove 23, and a connection hole 25 provided on the female buckle 20.

[0023] The outer contour of the female buckle body 21 is composed of two arc-shaped bosses, and both sides of the female buckle body 21 are arranged in a stepped shape. The female buckle body 21 includes a first boss 211 and a second boss 212 arranged above the first boss 211. In this embodiment, the diameter of the first boss 211 is smaller than the diameter of the face buckle 10, so that the contact area between the female buckle 20 and other objects is reduced, and the influence of the contact between the female buckle 20 and other structures on the fixing effect is avoided.

[0024] The center of the second boss 212 and the central axis of the first boss 211 are on the same straight line. The diameter of the second boss 212 is smaller than the diameter of the annular clearance groove, so that the face buckle 10 and the female buckle 20 are closer when installed.

[0025] The installation groove 22 is arranged in the first boss 211 and the second boss 212. The installation groove 22 starts from the side of the first boss 211 away from the second boss 212 and extends into the second boss 212. The installation groove 22 is frustum-shaped, and the central axis of the installation groove 22 is arranged on the same straight line as the first and second bosses 211, 212. The installation groove 22 is used to sleeved the screw sub-buckle 30. The installation groove 22 is arranged in cooperation with the screw sub-buckle 30. The diameter of the installation groove 22 is greater than or equal to the diameter of the screw sub-buckle 30 sleeved therein, so that the screw sub-buckle 30 can be sleeved in the installation groove 22 and the two are closely fitted.

[0026] The spring groove 23 is arranged on the side wall of the installation groove 22 and is located in the first boss 211, so that the spring 24 is buckled at the installation position of the screw sub-buckle 30 and the female buckle 20. The spring groove 23 is used to cooperate with the spring 24 to clamp the screw sub-buckle 30.

[0027] The spring 24 is an annular spring. The inner diameter of the spring 24 is smaller than the diameter of the installation groove 22, and the outer diameter of the spring 24 is larger than the diameter of the installation groove 22, so that the spring 24 can be clamped and installed on the spring groove 23. The central axis of the spring 24 and the central axis of the spring groove 23 are on the same straight line. Before the screw sub-buckle 30 is inserted and the spring 24 is not deformed, there is a gap between the spring 24 and the spring groove 23, and the gap between the spring 24 and the spring groove 23 is the deformation size when the spring 24 is sleeved on the screw sub-buckle 30. When the screw sub-buckle 30 is sleeved in the female buckle 20, the spring 24 is sleeved on the outside of the screw sub-buckle 30 and is elastically deformed by being stretched to eliminate the gap, so that the spring 24 is in contact with the side wall of the spring groove 23 and applies a fastening force to the screw sub-buckle 30, so that the screw sub-buckle 30 is clamped in the installation groove 22 by the spring 24.

[0028] The connecting hole 25 is used for passing through the hollow column of the face buckle 10, so that the face buckle 10 and the female buckle 20 are installed by riveting punching.

[0029] The screw sub-buckle 30 includes a clamping main body 31, a receiving groove 32 provided on the clamping main body 31, a nail part 33 provided on the receiving groove 32, a screw rod 34 provided below the clamping main body 31, and a guiding part 35 provided below the screw rod 34.

The clamping main body 31 includes a third boss 311 and a fourth boss 312 provided above the third boss 311. The centers of the third boss 311 and the fourth boss 312 are on the same straight line. The diameter of the third boss 311 is larger than the diameter of the installation groove 22, so as to prevent the third boss 311 from shifting after being installed in the female buckle 20, so as to confirm the fixed position after the anti-shake spring buckle is clamped with the female buckle 20. The diameter of the third boss 311 is smaller than the diameter of the first boss 211, so that the contact area between the third boss 311 and the outside is reduced, so that the screw sub-buckle 30 can be more stably clamped on the female buckle 20 and the shaking is reduced. When the screw sub-buckle 30 is installed with the female buckle 20, the fourth boss 312 is inserted into the installation groove 22, the fourth boss 312 is sleeved inside the first and second bosses 211 and 212, and the spring 24 is sleeved outside the fourth boss 312. One side of the third boss 311 facing the fourth boss 312 is attached to one side of the first boss 211 away from the second boss 212.

[0031] The central axis of the receiving groove 32 is the same as the central axes of the third and fourth bosses 311 and 312. The receiving groove 32 is used for receiving the hollow column in the processed cover column plate 12, and the depth of the receiving groove 32 is greater than the length of the processed hollow column.

[0032] The nail portion 33 is located on the same straight line as the central axis of the receiving groove 32 and the screw rod 34.

The nail portion 33 includes a lower bottom surface 331, an upper surface 332, and an inclined surface 333 connecting the lower bottom surface 331 and the upper surface 332. The lower bottom surface 331 is in the shape of a cross, and the upper surface 332 is in the shape of a circle after cutting, and its cutting shape is in the shape of a cross. The cross of the lower bottom surface 331 is smaller than the cross of the upper surface 332, and the cross cut on the upper surface 332 has the same center point as the cross of the lower bottom surface 331, so that the inclined surface 333 from the lower bottom surface 331 to the upper surface 332 is arranged in an inclined shape to facilitate the use of the screwdriver. The cross-shaped setting increases the contact area between the nail portion 33 and the matching screwdriver, and the right angle setting in the cross provides the screwdriver with clamping forces in different directions.

[0033] The central axes of the screw rod 34 and the nail portion 33 are arranged on the same straight line, the introduction portion 35 is arranged below the screw rod 34, and the screw rod 34 cooperates with the introduction portion 35 and the nail portion 33 to fix the screw button 30 on the object.

[0034] When in use, a hole is opened in the soft material, the face buckle 10 is inserted therein, and the female buckle 20 is inserted on the hollow column of the face buckle 10 through the connection hole 25 through the soft material. The second boss 212 and the face buckle 10 clamp the soft material and fit together. A riveting punch is used in the hollow column to rivet the face buckle 10 and the female buckle 20. The screw sub-button 30 is screwed into the hard material using an appropriate screwdriver. When installing, the clamping body 31 of the screw sub-button 30 is pressed into the installation groove 22 to fix the hard material and the soft material.

[0035] Compared with the prior art, the utility model provides a screw buckle that prevents shaking by setting the shapes of the clamping body 31 and the female buckle 20, so that the screw buckle 30 and the female buckle 20 are not easy to shake after installation. The diameter of the first boss 211 is smaller than the diameter of the face buckle 10, and the diameter of the third boss 311 is smaller than the diameter of the first boss 211, so that the contact area between the first boss 211 and the third boss 311 and the outside is reduced, so that the face buckle 10 and the female buckle 20, the screw buckle 30 and the female buckle 20 are more stable after installation and reduce shaking. The spring 24 is sleeved on the outside of the screw buckle 30 to increase the diameter of the screw buckle 30, and the spring 24 is attached to the side wall of the spring groove 23 to apply a tightening force to the screw buckle 30, so that the screw buckle 30 is clamped in the installation groove 22 by the spring 24. The nail part 33 is set in a cross groove, and the right angle in the cross groove increases the clamping force on the screwdriver to reduce shaking during installation.
