[0002] A hexagon head bolt is a screw rod with six external threads, and its head is hexagonal, which is used for fastening connection in cooperation with a nut. It is usually used in fields such as mechanical equipment, construction projects, and automobile manufacturing, and is an indispensable connecting element. Hexagon head bolts can be divided into ordinary bolts and bolts for reamed holes according to the force-bearing mode of connection. Ordinary bolts are used for general fastening connections, while bolts for reamed holes need to match the size of the hole and are used for connections subject to lateral forces. According to the head shape, hexagon head bolts have various types such as hexagon head, round head, square head, countersunk head, etc. Among them, hexagon head bolts are the most commonly used type because their head shape is easy to operate with tools such as wrenches.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a hexagon head bolt with a positioning bead on the head, including a bolt body 1, a hexagonal groove 2 is opened at the top of the bolt body 1, a braking assembly 3 is provided at the top of the bolt body 1, the braking assembly 3 is used to brake the bolt body 1, and a positioning assembly 4 is provided on the side of the bolt body 1, and the positioning assembly 4 is used to position the bolt body 1.

[0024] The braking assembly 3 includes fixing blocks 31 symmetrically arranged on the top surface of the bolt body 1. A rotating rod 32 is rotatably installed in the fixing block 31. A handle 33 is provided at the top of the rotating rod 32. Fixing frames 34 are provided on the left sides of the fixing blocks 31. Sliding plates 35 are slidably installed in the fixing frames 34. Insertion rods 36 are provided in the middle of the sliding plates 35, and the insertion rods 36 slide in the fixing frames 34. First springs 37 are wound around the surfaces of the insertion rods 36. Two groups of positioning grooves 38 are formed on the outer walls of the rotating rod 32 corresponding to the inner end surfaces of the insertion rods 36. The positioning assembly 4 includes a plurality of groups of sliding grooves 41 formed on the outer wall of the bolt body 1. Second springs 42 are provided on the inner walls of the sliding grooves 41. The other ends of the second springs 42 are fixedly connected with positioning beads 43, and the positioning beads 43 slide linearly in the sliding grooves 41.

[0025] By means of the braking assembly 3 provided at the top of the bolt body 1, the handle 33 drives the rotating rod 32 to rotate in the fixing block 31, and the handle 33 is rotated to be perpendicular to the top surface of the bolt body 1. At this time, the restoring force of the first spring 37 pushes the sliding plate 35 to slide in the fixing frame 34, and drives the insertion rod 36 to insert into a group of positioning grooves 38, so as to achieve the purpose of limiting the rotation of the handle 33. Then, by using the handle 33, the purpose of rotating the bolt body 1 is achieved, effectively solving the problem that the hexagonal groove 2 is damaged and the staff cannot rotate the bolt body 1. By means of the positioning assembly 4 provided on the side of the bolt body 1, when the bolt body 1 is installed on an object, the through hole on the object is aligned with the positioning bead 43. At this time, the restoring force of the second spring 42 pushes the positioning bead 43 to slide and reset in the sliding groove 41, and abuts against the through hole on the object, so as to achieve the purpose of self-locking of the bolt body 1, preventing the bolt body 1 from loosening or falling off under vibration or impact.

[0026] As Figure 5 shown, the handle 33 is designed in a cylindrical shape. Anti-slip patterns are provided on the outer wall of the handle 33. An anti-slip rubber sleeve can also be sleeved on the handle 33, which can increase the friction between the staff's hand and the handle 33, so that when the handle 33 drives the bolt body 1 to rotate, it is not easy to slip, thus improving the stability of the handle 33 during use.

[0027] As Figure 5 shown, connecting plates 39 are fixedly connected to the outer end surfaces of the insertion rods 36. The connecting plates 39 are designed in a C shape, which enables the staff to operate the two insertion rods 36 simultaneously through the connecting plates 39, thereby improving the operation efficiency of the staff for the two insertion rods 36.

[0028] As Figure 2As shown, the positioning bead 43 is designed in a spherical shape, and a through hole adapted to the positioning bead 43 is provided on the object. By threadedly connecting the bolt body 1 to the object, the positioning bead 43 is aligned with the through hole on the object. Then, the restoring force of the second spring 42 is used to push the positioning bead 43 to slide back in the chute 41 and abut against the through hole on the object, thereby achieving the purpose of self-locking the bolt body 1.

[0029] As Figure 2 shown, six groups of chutes 41 are provided. The six groups of chutes 41 are all equidistantly arranged on six surfaces of the outer wall of the bolt body 1, which can increase the self-locking strength of the positioning bead 43 on the bolt body 1 and prevent the positioning bead 43 from sliding out of the through hole when the bolt body 1 is subjected to vibration or impact, thereby preventing the bolt body 1 from loosening.

[0030] The usage method and working principle of this device: When in use, first pull the connecting plate 39 in the direction away from the fixed block 31, so that the connecting plate 39 drives the two groups of insertion rods 36 to slide in the fixed frame 34, and the insertion rods 36 synchronously drive the sliding plate 35 to slide in the fixed frame 34, and the sliding plate 35 squeezes the first spring 37. At the same time, the insertion rods 36 slide out of the positioning grooves 38. Then, rotate the handle 33, so that the handle 33 drives the rotating rod 32 to rotate in the fixed block 31, and the handle 33 rotates from the top surface of the bolt body 1 to a state perpendicular to the top surface. At this time, another group of positioning grooves 38 on the rotating rod 32 are aligned with the insertion rods 36 as the handle 33 rotates. Then, release the connecting plate 39, and use the restoring force of the first spring 37 to push the sliding plate 35 to slide back in the fixed frame 34, and the sliding plate 35 synchronously drives the insertion rods 36 to insert into the positioning grooves 38, thereby achieving the purpose of restricting the rotation of the handle 33. Then, by using the handle 33, the bolt body 1 is rotated.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
