Description

Technical Field

[0001] The utility model relates to the field of bolts, in particular to a hexagonal bolt with double bolt heads and high stability. Background Art

[0002] As a common fastener, stud bolts play an irreplaceable role in machinery, construction, automobiles, aerospace and other fields. However, with the continuous advancement of science and technology and the rapid development of industry, the stability and performance requirements of stud bolts are becoming higher and higher. Under this background, it is particularly important to develop a stud bolt with good stability. During the use of traditional stud bolts, due to the influence of factors such as materials, processes or environment, problems such as loosening, breaking or corrosion often occur. These problems not only affect the service life of the stud bolts, but may also pose a threat to the stability and safety of the entire system. Therefore, how to improve the stability of stud bolts and reduce the problems that occur during their use has become an urgent problem to be solved. Utility Model Content

[0003] The utility model provides a double-bolt head hexagonal bolt with strong stability, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] A double-bolt head hexagonal bolt with high stability, comprising a bolt body and a nut, wherein the nut is sleeved outside the bolt body, the bottom of the bolt body has a tubular hole, and both sides of the tubular hole are connected to the outside through an opening respectively, and an anti-slip component is arranged in the tubular hole, and the anti-slip component protrudes outward through the openings on both sides and abuts against the inner surface of the nut;

[0006] The anti-dropping component extends along the length direction of the opening.

[0007] A preferred technical solution: The anti-slip assembly includes a rotationally symmetrically arranged reinforcement strip, the lower parts of the two reinforcement strips are connected to the inner side of the tubular hole, and the upper parts of the two reinforcement strips gradually extend toward the middle of the upper end of the tubular hole, there is a spacing between the two reinforcement strips, and the upper parts of the two reinforcement strips are connected by a connecting strip;

[0008] When the connecting strip is broken, the two reinforcing strips protrude outward through the adjacent openings and abut against the inner side surface of the nut.

[0009] A better technical solution: the outer side of the reinforcement strip is provided with an anti-slip protrusion, and the anti-slip protrusion extends along the length direction of the reinforcement strip. When the reinforcement strip protrudes outward from the opening, the anti-slip protrusion presses against the inner surface of the nut and is embedded in the thread on the inner surface of the nut.

[0010] Compared with the prior art, this technical solution has the following advantages:

[0011] Since the nut and the bolt body form a threaded connection, the inner surface of the nut has a thread groove. When the anti-slip component is against the nut, it will be embedded in the thread groove, so that when the nut rotates, force will be applied to the anti-slip component at the same time. Since the anti-slip component is connected to the inner side of the bolt body and does not have a large range of movement, it can form a circumferential rotation limit for the nut when it rotates, forming a limiting and anti-slip effect; and, the reinforcement strip has inclined ends from bottom to top. When the connecting strip is cut off and the reinforcement strip is against the inner side of the nut, the upper side of the anti-slip protrusion will protrude from the side of the bolt body and against the surface of the fixed object, thereby increasing the grip effect.

[0018] like Figure 1-Figure 4As shown, a hexagonal bolt with double bolt heads with high stability includes a bolt body 1 and a nut 2. The nut 2 is sleeved outside the bolt body 1. The bottom of the bolt body 1 has a tubular hole, and the two sides of the tubular hole are connected to the outside through an opening 11 respectively. An anti-slip component is arranged in the tubular hole, and the anti-slip component protrudes outward through the openings 11 on both sides and abuts against the inner surface of the nut 2. The anti-slip component extends along the length direction of the opening 11. Based on this, it can be known that the stud bolt in the utility model can be tightened by the nut 2 in use. To form a fixation, when fixed, the anti-slip component can protrude outward through the opening 11 and abut against the inner surface of the nut 2 to form a butting effect. Since the nut 2 and the bolt body 1 form a threaded connection, the inner surface of the nut 2 has a thread groove. When the anti-slip component abuts against the nut 2, it will be embedded in the thread groove, so that when the nut 2 rotates, force will be applied to the anti-slip component at the same time. Since the anti-slip component is connected to the inner side of the bolt body 1, it does not have a large range of movement. Therefore, when the nut 2 rotates, it can form a circumferential rotation limiting effect.

[0019] Furthermore, the anti-slip assembly includes a rotationally symmetrically arranged reinforcement strip 13, the lower parts of the two reinforcement strips 13 are connected to the inner side of the tubular hole, and the upper parts of the two reinforcement strips 13 gradually extend toward the middle part of the upper end of the tubular hole, there is a spacing between the two reinforcement strips 13, and the upper parts of the two reinforcement strips 13 are connected by a connecting strip 132; when the connecting strip 132 is broken, the two reinforcement strips 13 protrude outward through the adjacent openings 11 and abut against the inner side of the nut 2, so when in use, the bolt body 1 and the nut 2 can be installed first, and then the connecting strip 132 can be cut off by a tool, so that the two reinforcement strips 13 can swing outward and protrude through the opening 11, thereby abutting against the inner surface of the nut 2, forming a limiting and anti-slip effect;

[0020] And if Figure 2 , Figure 3 As shown, the reinforcing strip 13 has inclined ends from bottom to top. When the connecting strip 132 is cut off and the reinforcing strip 13 is pressed against the inner side of the nut 2, the upper side of the anti-slip protrusion 131 will also protrude from the side of the bolt body 1 and press against the surface of the fixed object to increase the grip effect.

[0021] In addition, an anti-slip protrusion 131 is provided on the outer side of the reinforcement strip 13, and the anti-slip protrusion 131 extends along the length direction of the reinforcement strip 13. When the reinforcement strip 13 protrudes outward from the opening 11, the anti-slip protrusion 131 presses against the inner surface of the nut 2 and is embedded in the thread on the inner surface of the nut 2.

[0022] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
