Description

Technical Field

[0001] This utility model relates to the field of screw technology, and in particular to an external hexagonal screw. Background Technology

[0002] Screws play a vital role in industry, and their function will remain important as long as industry exists on Earth. Some screws have hexagonal heads and require an external wrench to turn them. During installation, screws are typically aligned manually with the threaded hole, then screwed in partially until they can no longer be turned by hand, at which point a wrench is used to tighten them. However, for longer screws, manual tightening is cumbersome and inefficient. Utility Model Content

[0003] The present invention aims to solve, at least to some extent, one of the problems existing in the prior art. To this end, the present invention proposes an external hexagonal screw.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An external hexagonal screw includes a screw rod and a hexagonal nut at one end of the screw rod. A transverse groove is provided on the upper end face of the hexagonal nut. A rotating auxiliary component is hinged in the transverse groove. The rotating auxiliary component can be flipped out of the transverse groove or stored in the transverse groove.

[0006] In some embodiments, the rotating auxiliary component includes a support block, a rotating shaft disposed at one end of the support block, and a rotating rod rotatably disposed at the other end of the support block, wherein the two ends of the rotating shaft are rotatably disposed at one end of the transverse groove.

[0007] In some embodiments, a limiting seat is provided at one end of the transverse groove near the rotating shaft. When the support block flips out of the transverse groove along with the rotating shaft, one side of the support block can abut against the limiting seat, so that the support block and the rotating rod remain vertically flipped out of the transverse groove.

[0008] In some embodiments, a limiting protrusion is provided on the inner sidewall of the transverse groove. The limiting protrusion cooperates with the support block, thereby keeping the support block vertically flipped out of the transverse groove or horizontally stored inside the transverse groove.

[0009] In some embodiments, the transverse groove extends laterally along one of the diagonal directions of the hexagonal nut.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: a horizontal groove is provided on the upper end face of the hexagonal nut, and a rotating auxiliary component is hinged in the horizontal groove. The rotating auxiliary component can be flipped out of the horizontal groove or stored in the horizontal groove. That is to say, when it is necessary to tighten the screw, the rotating auxiliary component can be flipped out of the horizontal groove, and then the rotating auxiliary component can be manually held by hand to rotate it, which can improve the screw rotation effect, facilitate the installation and disassembly of the screw, and is particularly suitable for the use of long screws. When the rotating auxiliary component is not in use, it can be directly flipped back into the horizontal groove for storage, making it flexible and convenient to use. Attached Figure Description

[0013] Figure 3 This is a schematic diagram of the rotating auxiliary component of this utility model when it is flipped in the transverse groove. Detailed Implementation

[0014] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0015] like Figures 1-3 The external hexagonal screw shown includes a screw rod 1 and a hexagonal nut 2 located at one end of the screw rod 1. A transverse groove 3 is provided on the upper end face of the hexagonal nut 2. A rotating auxiliary component 4 is hinged in the transverse groove 3. The rotating auxiliary component 4 can be flipped out of the transverse groove 3 or stored in the transverse groove 3.

[0016] According to the above structure, when it is necessary to tighten the screw, the rotating auxiliary part 4 can be flipped out from the horizontal groove 3, and then the rotating auxiliary part 4 can be rotated manually by hand, which can improve the screw rotation effect, facilitate the installation and disassembly of the screw, and is especially suitable for the use of long screws. When the rotating auxiliary part 4 is not in use, it can be directly flipped back into the horizontal groove 3 for storage, making it flexible and convenient to use.

[0017] Furthermore, the rotating auxiliary component 4 includes a support block 21, a rotating shaft 22 located at one end of the support block 21, and a rotating rod 23 rotatably located at the other end of the support block 21. The two ends of the rotating shaft 22 are rotatably located at one end of the transverse groove 3. Of course, a rotating shaft body 24 is provided at the end where the support block 21 is connected to the rotating rod 23. The rotating rod 23 is rotatably connected to the rotating shaft body 24, so that when the rotating rod 23 and the support block 21 are flipped upwards out of the transverse groove 3, the rotating rod 23 can rotate smoothly.

[0018] When the rotating rod 23 and the support block 21 are housed in the horizontal groove 3, they will not protrude out of the horizontal groove and will not affect the fit between the wrench and the hexagonal nut 2.

[0019] See Figure 2 , Figure 3 As shown, a limiting seat 31 is provided at one end of the transverse groove 3 near the rotating shaft 22. When the support block 21 flips out of the transverse groove 3 along with the rotating shaft 22, one side of the support block 21 can abut against the limiting seat 31, so that the support block 21 and the rotating rod 23 remain vertically flipped out of the transverse groove 3.

[0020] Furthermore, a limiting protrusion 41 is provided on the inner side wall of the transverse groove 3. The limiting protrusion 41 cooperates with the support block 21, thereby keeping the support block 21 vertically flipped out of the transverse groove 3 or horizontally stored in the transverse groove 3.

[0021] In other words, when the rotating rod 23 and the support block 21 are flipped out of the transverse groove 3, one side of the support block 21 abuts against the limiting seat 31, while the other end is limited by the limiting protrusion 41, keeping the support block 21 in a vertical state. In addition, when the support block 21 is flipped downward and stored in the transverse groove 3, one side of the rotating rod 23 abuts against the bottom wall of the transverse groove 3, while one side of the support block 21 is limited by the limiting protrusion 41, keeping the support block 21 and the rotating rod 23 in a horizontal state. Of course, it should be noted that the limiting protrusion 41 does not protrude too much, and the support block 21 can be driven to flip by hand, but the support block 21 cannot be flipped without external force.

[0022] In this invention, the transverse extension direction of the transverse groove 3 is set along one of the diagonal directions of the hexagonal nut 2, thereby maximizing the transverse length of the transverse groove 3, and thus maximizing the extension length of the rotating rod 23.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
