Technical Field
[0001] The utility model belongs to the technical field of bolts, in particular to an improved shockproof bolt for automobiles. Background Art
[0002] Bolt: A mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which must be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
[0003] The bolts used in the upper part of the shockproof car are usually prevented from loosening by using washers. However, when the bolts are prevented from loosening by using washers, the bolt bodies will also become loose after long-term use, so that the bolts do not have a good anti-loosening effect. For this reason, we propose an improved shockproof car bolt. Utility Model Content

[0023] Embodiment 1, by Figure 1-3 Provided is an improved anti-vibration bolt for automobiles, comprising a bolt 10 and a nut 20, wherein the nut 20 is screwed onto the upper portion of the bolt 10;
[0024] The bolt 10 includes a twisting block 11, a threaded forward rotating screw 12 and a threaded reverse rotating screw 13. The threaded forward rotating screw 12 is installed at the bottom of the twisting block 11. The threaded reverse rotating screw 13 is plug-connected with the threaded forward rotating screw 12. A slot 120 is provided at the bottom of the threaded forward rotating screw 12.
[0025] The inside of the reverse-rotating screw rod 13 of the thread pattern is evenly provided with action grooves 130, and the inside of the action groove 130 is provided with a spring 131, and the other end of the spring 131 is provided with a clamping block 132, and the clamping block 132 is clamped with the clamping groove 120. When the device is used, the bolt 10 can be fixed to the upper part of the automobile accessory by rotating the nut 20, and the bolt 10 can be fixed by the rotation of the nut 20, so that the bolt 10 can be better screwed and fixed. After the nut 20 is screwed, the bolt 10 can be rotated by rotating the screwing block 11 when it is screwed, and the rotation of the screwing block 11 drives the thread-shaped forward-rotating screw rod 12 to rotate, and the rotation of the thread-shaped forward-rotating screw rod 12 makes The nut 20 can be tightened better, and the reverse-rotating screw 13 is rotated by rotating the reverse-rotating screw 13, and the reverse-rotating screw 13 is screwed into the inside of the nut 20, so that the reverse-rotating screw 13 and the forward-rotating screw 12 fit together, and when the reverse-rotating screw 13 is rotating, the clamping block 132 will be clamped in the inside of the clamping groove 120, thereby limiting the position of the reverse-rotating screw 13, and by providing the action groove 130, the position of the spring 131 and the clamping block 132 can be limited, so that the clamping block 132 can better perform the upward and downward extension work, and the position of the nut 20 is limited by the forward-rotating screw 12 and the reverse-rotating screw 13, so as to avoid the nut 20 from being screwed. The automatic loosening phenomenon occurs, and the position of the reverse-rotating screw rod 13 of the silk pattern is limited by a clamping method to prevent the reverse-rotating screw rod 13 of the silk pattern from automatically rotating in the reverse direction. A through groove is provided inside the forward-rotating screw rod 12 of the silk pattern, and a column is provided on the upper part of the reverse-rotating screw rod 13 of the silk pattern. The column and the through groove are plug-connected. By providing the through groove, the position of the column can be effectively limited, so that when the reverse-rotating screw rod 13 of the silk pattern is rotating, the column can correct the position of the reverse-rotating screw rod 13 of the silk pattern, and assist the reverse-rotating screw rod 13 to rotate and tighten better. The shape of the clamping groove 120 is an inverted triangle, and the shape of the clamping block 132 is a triangle.
