Description

Technical Field

[0001] The utility model relates to the field of engines, in particular to an anti-slip hexagon socket bolt and a hexagon socket screwdriver. Background Art

[0002] In the field of mechanical manufacturing, hexagon socket bolts are widely used due to their compact structure and stable connection. However, in actual use, due to differences in bolt materials and inertia during operation, hexagon socket bolts often slip during tightening. This slippage not only affects the tightening effect of the bolts, but can also cause operator injury and pose a safety hazard to production.

[0003] While there are many types of hexagon socket bolts on the market, no product has yet been found that effectively solves the slippage problem. Traditional hexagon socket bolt designs primarily rely on a hexagonal internal groove structure, which provides a stable connection when the force is evenly distributed. However, under high torque or when the material is insufficiently hard, the hexagonal internal groove structure is prone to slippage due to insufficient friction, thereby reducing the bolt's tightening performance and operational safety. Utility Model Content

[0004] The utility model aims to provide an anti-skid hexagon socket bolt and a hexagon socket screwdriver, so as to solve the problem of easy slipping in the prior art.

[0005] The utility model is realized by adopting the following technical scheme: an anti-skid hexagon socket bolt comprises a bolt body, the upper end surface of the bolt body is provided with a hexagonal groove, the hexagonal groove is provided with an anti-skid protrusion, and the anti-skid protrusion is a prism.

[0006] Furthermore, the protrusion distance of the anti-slip protrusion is 1 / 2 of the depth of the hexagonal groove, so as to ensure the external dimension structure of the original hexagon socket bolt without increasing the cost of raw materials.

[0007] Furthermore, the anti-slip protrusion is a triangular prism, and the cross-sectional shape of the anti-slip protrusion on the rotation axis of the hexagon socket bolt is a triangle to maximize friction.

[0008] Furthermore, one of the side surfaces of the anti-slip protrusion is parallel to one side surface of the hexagonal groove, and the geometric center of the cross section of the anti-slip protrusion on the rotation axis of the hexagonal socket bolt and the geometric center of the cross section of the hexagonal socket groove on the rotation axis of the hexagonal socket bolt are both located on the rotation axis of the hexagonal socket bolt.

[0009] Furthermore, the triangular side length of the anti-slip protrusion cross section is greater than 2 / 3 of the hexagonal side length of the hexagonal groove cross section, and the anti-slip protrusion is an equilateral triangle.

[0010] Furthermore, the bolt body adopts a bolt larger than M4.

[0011] A hexagonal screwdriver for use with an anti-slip hexagonal screw bolt comprises a screwdriver body. The screwdriver body has the same shape as a hexagonal groove and can be inserted into the hexagonal groove. An anti-slip groove having the same shape as an anti-slip protrusion is provided on the end surface of the screwdriver body. When the screwdriver body is inserted into the hexagonal groove, the anti-slip protrusion is also inserted into the anti-slip groove.

[0012] The anti-slip hexagon socket bolt and hexagon socket screwdriver described in the utility model have the following beneficial effects:

[0013] Significantly Improved Anti-Slip Performance: The raised portion of the triangular prism structure increases the contact area and friction between the screwdriver and the screwdriver, effectively preventing slipping during tightening. This design not only improves bolt tightening performance but also reduces the risk of operator injury.

[0014] Maintaining the original hexagon socket bolt's usability: The new anti-slip hexagon socket bolt maintains its basic shape and dimensions, making it compatible with existing hexagon socket drivers. This feature allows for easy upgrades to existing equipment without having to replace existing drivers or bolt holes, reducing retrofit costs.

[0015] Cost is the same as that of an existing hexagon socket bolt: Since the non-slip hexagon socket bolt of this utility model does not increase the cost of raw materials and the production process is relatively simple, its overall cost is comparable to that of an existing hexagon socket bolt. This advantage makes the non-slip hexagon socket bolt of this utility model more competitive in the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0023] like Figure 1-3 As shown, a non-slip hexagon socket bolt and a hexagon socket driver, wherein the hexagon socket bolt includes a bolt body, the upper end surface of the bolt body 1 of the bolt body is provided with a hexagonal groove 2, and the hexagonal groove 2 is provided with an anti-slip protrusion 3. The hexagonal socket driver includes a driver body 4, the driver body 4 is the same shape as the hexagonal groove 2 and can be inserted into the hexagonal groove 2, and the end surface of the driver body 4 is provided with an anti-slip groove 5, the anti-slip groove 5 is the same shape as the anti-slip protrusion 3, when the driver body 4 is inserted into the hexagonal groove 2, the anti-slip protrusion 3 is also inserted into the anti-slip groove 5.

[0024] The anti-slip protrusion 3 is a triangular prism, with a triangular cross-section along the rotation axis of the hexagon socket bolt. The protrusion distance of the anti-slip protrusion 3 is half the depth of the hexagonal groove 2. This design maintains the original dimensions of the hexagon socket bolt without increasing the cost of raw materials. The bolt head length can also be increased according to actual requirements. Both methods can meet the requirements of the original hexagon socket bolt driver and can be used uniformly, thus saving costs.

[0025] The anti-slip projection 3 effectively prevents slipping during the use of the hexagon socket bolt. While it can also be a polygonal shape, such as a rectangular or pentagonal column, the frictional force decreases as the number of sides increases, so a triangular column is the optimal choice. It can also be used to tighten the bolt when the original hexagon socket's rotation function fails.

[0026] One side of the anti-slip protrusion 3 should be parallel to one side of the hexagonal groove 2. The geometric center of the cross section of the anti-slip protrusion 3 on the rotation axis of the hexagonal socket bolt and the geometric center of the cross section of the hexagonal groove 2 on the rotation axis of the hexagonal socket bolt are both located on the rotation axis of the hexagonal socket bolt. The triangular side length of the anti-slip protrusion 3 cross section is greater than 2 / 3 of the hexagonal side length of the hexagonal groove 2 cross section and is an equilateral triangle. The bolt body 1 uses a bolt of M4 or larger.

[0027] The above embodiments describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Without departing from the spirit and scope of the present invention, modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the scope of protection of the appended claims.
