Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a hexagon bolt, as shown in fig. 1 and 2, which comprises a rod part 1 and a head part 2 which are fixedly connected, wherein the head part 2 is in a regular hexagon shape and is positioned on the upper side of the rod part 1, and the outer surface of the rod part 1 is provided with an external thread extending along the vertical direction. The up end of head 2 is equipped with mounting groove 3, and the cross section of mounting groove 3 is regular hexagon and with the axis collineation of head 2.

As shown in fig. 1 and 2, a material saving groove 4 extending in the vertical direction is formed in the lower end surface of the rod portion 1, and an internal thread is formed on the inner wall of the material saving groove 4. The material-saving groove 4 reduces production materials of the rod part 1 on the premise of not influencing the fastening performance of the bolt, and saves energy consumption. In addition, people can also be with pole portion 1 and the 4 screw connection of 4 screw-thread fit's in festival material groove bolt and festival material groove 4, occupation space when having reduced and accomodating a plurality of bolts. The bottom surface of mounting groove 3 is equipped with the through-hole 5 with festival silo 4 intercommunication, and people can pour into lubricating fluid such as engine oil into to festival silo 4 by through-hole 5, has increased the lubricating property of bolt, the convenient rotation.

As shown in fig. 3 and 4, the front and rear end surfaces of the head 2 are provided with fixing grooves 6 extending in the horizontal direction, the right end of the fixing groove 6 is hinged with a moving rod 7, and the left inner wall of the fixing groove 6 is provided with a positioning groove 8. During dismouting bolt, people's accessible rotates transfer bar 7 for the axle center along its articulated department with head 2 for transfer bar 7 stretches out fixed slot 6 and makes its and fixed slot 6's right side inner wall butt, and the rethread rotates transfer bar 7 and makes its drive head 2 rotate, and then drives the rotation of pole portion 1 rotation in order to realize the bolt. One can adjust the direction of rotation of the bolt by turning two different travel bars 7 to control the loosening or tightening of the bolt. When the movable rod 7 is not used, the movable rod 7 is rotated into the fixed groove 6 to reduce the occupied space of the whole bolt.

As shown in fig. 3 and 4, an extension groove 9 is provided on an end surface of the moving rod 7 away from the hinge joint with the head 2, the extension groove 9 extends in the horizontal direction, and an extension rod 10 is slidably provided in the extension groove 9. The inner wall of the extension groove 9 far away from the fixing groove 6 is provided with a moving hole 11 extending along the horizontal direction, a push block 12 is arranged in the moving hole 11 in a sliding manner, and the push block 12 is fixed at one end of the extension rod 10 close to the hinged position of the extension rod and the head 2. When the movable rod 7 stretches out the fixed slot 6, the push block 12 is pushed by hand to move towards one side of the hinged end far away from the movable rod 7 and the head 2, the extension rod 10 moves along with the push block and stretches out the extension slot 9, and at the moment, the extension rod 10 can drive the head 2 to rotate, so that the moment is increased, and the labor-saving effect is achieved. When the movable rod 7 withdraws the fixing groove 6, the extension rod 10 extends into the positioning groove 8 through the push block 12, and the movable rod 7 is limited by the side wall of the positioning groove 8 and is not easy to separate from the fixing groove 6.

As shown in fig. 2 and 3, a plurality of anti-slip blocks 13 are fixed on the surface of the push block 12, and the anti-slip blocks 13 increase the friction force between the human hand and the push block 12, so that the human hand is not easy to slip when moving the push block 12.

As shown in fig. 3 and 4, a stopper 14 is fixed on an end surface of the push block 12 away from the hinge joint of the moving rod 7 and the head 2, and the stopper 14 is made of an elastic material and is hemispherical. The end face of the movable hole 11 far away from the hinged position of the movable rod 7 and the head 2 is provided with a clamping groove 15, and the clamping groove 15 is hemispherical and is in interference fit with the clamping block 14. When the extension rod 10 extends out of the extension groove 9, the push block 12 is moved to enable the clamping block 14 and the clamping groove 15 to be in interference fit, so that the extension rod 10 is not easy to retract into the extension groove 9, and the stability of the extension rod 10 is improved.

The working principle of the embodiment is as follows: when dismouting bolt, earlier make extension rod 10 and constant head tank 8 separation through ejector pad 12, again with ejector pad 12 to keeping away from one side pulling of fixed slot 6 so that the carriage release lever 7 rotates out fixed slot 6, make the one end of extension rod 10 stretch out extension tank 9 again, people's accessible rotates extension rod 10 and makes its drive head 2 rotate and need not with the help of specialized tool such as spanner, easy dismounting.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
