[0002] Both ends of the stud hexagon bolt can be used for connection. Usually, a nut is screwed on each end, but a single nut is difficult to prevent from falling off. If the external environment keeps vibrating for a long time, the nut is easy to loosen. Therefore, the utility model proposes an anti-falling stud hexagon bolt. Utility Model Content

[0003] The utility model aims to overcome the deficiencies in the prior art and provide an anti-loosening double-headed hexagonal bolt, which has the characteristics of convenient screwing and anti-loosening.

[0004] To solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves an anti-slip stud hexagon bolt, including a rotating part in the shape of a non-rotating column, and both ends of the rotating part are respectively provided with stud parts extending linearly along its length direction, and a non-standard nut is threadedly connected to the stud part. The side of the stud part is surrounded by a plurality of stop grooves extending along the axial direction, and at least one end of the non-standard nut is provided with a stop ring close to the center hole, and the stop ring is provided with side openings equal to the number of the stop grooves and matched one by one, and a stop spring is provided in the side opening, and one end of the stop spring is connected to the wall of the side opening, and the other end extends into the stop groove.

[0005] The utility model is further configured that: the interval angles between two adjacent stop grooves are equal.

[0006] The utility model is further configured as follows: the number of the retaining grooves is four.

[0007] The utility model is further configured as follows: a stop ring close to the center hole is provided at one end of the non-standard nut.

[0008] The utility model is further configured as follows: the rotating part is in the shape of a regular hexagonal prism.

[0009] To sum up, the utility model has the following beneficial effects: the anti-slip stud hexagonal bolt involved in the utility model, by opening a stop groove on the stud part of the stud bolt, matched with the stop spring piece on the non-standard nut, makes the non-standard nut in rotation unable to reverse, achieves the effect of only moving forward but not backward, thereby playing an anti-slip effect, is easy to rotate and prevent loosening, has perfect overall functions and strong practicality.

[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 and Figure 2 As shown, the present embodiment involves an anti-slip stud hexagonal bolt, comprising a rotating portion 1 in the shape of a regular hexagonal prism, wherein both ends of the rotating portion 1 are respectively provided with a stud portion 2 extending linearly along its length direction, a non-standard nut 3 is threadedly connected to the stud portion 2, and four stop grooves 4 extending along the axial direction are arranged around the side surface of the stud portion 2, and the interval angles between two adjacent stop grooves 4 are equal, one end of the non-standard nut 3 is provided with a stop ring 5 close to the center hole, and the stop ring 5 is provided with side openings 6 equal to the number of the stop grooves 4 and matched one by one, a stop spring piece 7 is provided in the side opening 6, and one end of the stop spring piece 7 is connected to the wall of the side opening 6 and the other end extends into the stop groove 4.

[0016] In this embodiment, when the non-standard nut 3 is screwed onto the stud portion 2, during the screwing process, the stop spring piece 7 continuously switches between the movement state of disengaging from the stop groove 4 and the movement state of extending into the stop groove 4. Because one end of the stop spring piece 7 is connected to the wall of the side opening 6, when the non-standard nut 3 is rotated in the reverse direction, the other end of the stop spring piece 7 will abut against the wall of the stop groove 4, thereby playing a locking role and preventing reverse rotation.

[0017] The anti-slip double-headed hexagonal bolt involved in the utility model has a stopping groove on the stud part of the double-headed bolt, which is matched with the stopping spring piece on the non-standard nut, so that the non-standard nut cannot be reversely rotated during rotation, so as to achieve the effect of only moving forward but not backward, thereby playing the role of anti-slipping, convenient rotation and anti-loosening, with perfect overall function and strong practicality.

[0018] Unless otherwise specified, in the present invention, the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicating orientation or positional relationship are based on the orientation or positional relationship actually shown, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation.
