Description

Technical Field

[0001] The utility model relates to the technical field of double-head self-tapping screws, in particular to anti-deformation double-head self-tapping screws. Background Art

[0002] The double-headed self-tapping screw has threaded heads in both directions. When using it, it is necessary to operate it with physical strength and protect it to prevent it from deforming during use. After searching, the Chinese patent authorization number CN216842580U discloses an anti-deformation double-headed self-tapping screw, including a U-shaped frame, a double-headed self-tapping screw, a mounting hole, a rotating shaft, a socket, a limit hole, a limit rod, an anti-slip block, a first spring, a pressure rod, a slide groove, a slider and a locking mechanism. The inner side of the U-shaped frame is provided with a double-headed self-tapping screw, and the left and right sides of the double-headed self-tapping screw are both provided with mounting holes. The two mounting holes are symmetrically arranged, and the left inner wall and the right inner wall of the U-shaped frame can be rotatably provided with a rotating shaft. The two rotating shafts are symmetrically arranged, and the two rotating shafts are respectively inserted in the two mounting holes. The rotating shaft and the mounting hole are axially slidably matched, and the left and right sides of the double-headed self-tapping screw are both provided with two sockets, and the four sockets are distributed in a square array. Compared with the prior art, the self-tapping screw can be installed conveniently and quickly, and the wear or deformation of the double-headed self-tapping screw can be effectively prevented. The structure is simple, easy to use, and easy to promote and apply. However, the protective device can only clamp the screw body and limit it. After clamping, it is clamped by springs on both sides. When the device rotates due to the tightening device, the rotation speed is fast, which will cause the spring to shake, thereby easily loosening the clamping devices on both sides and causing the internal stud screws to fall off. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an anti-deformation double-headed self-tapping screw, which solves the problem that the protective device can only clamp the screw body and limit it. After clamping, it is clamped by springs on both sides. When the device rotates due to the tightening device, the rotation speed is relatively fast, which will cause the spring to shake, thereby easily loosening the clamping devices on both sides and causing the internal double-headed screw to fall off.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: an anti-deformation double-headed self-tapping screw, including a double-headed screw and a connecting seat, the side wall of the double-headed screw is symmetrically slidably connected to a limiting block, the connecting seat is provided with a connecting hole, and the side walls on both sides of the connecting hole are provided with limiting grooves, the right side of the connecting seat is fixedly connected to a connecting pipe, and the limiting block is slidably connected to the inside of the limiting groove through the double-headed screw.

[0005] Preferably, the portion where the limit block is connected to the stud screw is hollow, and tension springs are fixedly connected between adjacent stud screws, so that the limit blocks on both sides can move to both sides.

[0006] Preferably, the side wall of the connecting tube is symmetrically rotatably connected to a fixing rod, the side wall of the fixing rod is fixedly connected to a U-shaped handle, and a screwdriver groove is provided inside the right side wall of the connecting tube, so that the double-headed screw can be rotated more conveniently.

[0007] Preferably, the inner diameter of the connecting tube is equal to the diameter of the connecting hole, so that after the stud screw is inserted into the interior of the connecting seat, the screw portion can enter the interior of the connecting tube.

[0008] Preferably, the stud screw is symmetrically provided with moving grooves inside, and the side walls on both sides of the limit block are symmetrically fixedly connected with moving blocks, and the moving blocks are slidably connected to the inside of the moving grooves, so that the limit block can be conveniently limited.

[0009] The utility model provides an anti-deformation double-head self-tapping screw, which has the following beneficial effects:

[0010] The anti-deformation double-headed self-tapping screw can, when the double-headed self-tapping screw is used, allow the double-headed screw to enter the interior of the connecting seat through the provided connecting seat, and allow the limiting block to enter the interior of the limiting groove, so that even when the device is rotating, the position of the double-headed screw will not be loosened;

[0011] The anti-deformation double-headed self-tapping screw is rotatably connected to the connecting pipe through a fixed rod when the double-headed self-tapping screw is used, so that when the double-headed screw is placed, it can be manually twisted to prevent the position of the double-headed screw from being tilted and causing damage when the double-headed screw is turned.
