Description
Technical Field
The utility model belongs to the technical field of the fastener, specifically speaking especially relates to an antiskid thread bolt structure.
Background
A bolt is a cylindrical threaded fastener fitted with a nut. The bolt is divided into the following parts according to the shape of the head: with hex heads, round heads, square heads, countersunk heads, etc., with hex heads being most commonly used. The bolt has simple structure, convenient use and good effect, and is widely used in various occasions.
When the bolt fastener is used, enough pretightening force needs to be ensured, but the bolt fastener cannot be screwed too tightly, and if the bolt fastener is screwed too tightly, the connecting piece can generate permanent deformation under the action of external force. In some vibration situations, bolts used for fastening are often loosened, and the connection is disconnected. When the outer wall of the nut is damaged to cause the phenomenon of bolt wire slipping, the manufacturing of the bolt capable of effectively preventing the loosening and the wire slipping becomes very urgent.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides an antiskid silk bolt structure prevents not hard up, and the buffering is hit, needs to possess good elasticity and shock resistance performance such as.
The purpose of the utility model can be realized by the following technical scheme: an anti-slip thread bolt structure comprises a bolt head, wherein a screw rod is fixedly connected to the lower surface of the bolt head, threads are arranged on the screw rod, a hexagon socket is formed in the center of the bolt head, hemispheres are symmetrically and fixedly connected to two sides of the hexagon socket on the bolt head, through holes are formed in the hemispheres, and pull rings are sleeved in the through holes;
the lower surface of the bolt head is provided with a circle of bulges at the outer side of the screw rod, and the bulges are connected to form a corrugated shape;
one end of the screw rod, which is far away from the bolt head, is provided with a truncated cone-shaped guide rod, a guide thread is arranged on the guide rod, and the angle of the guide thread is 30-45 degrees.
Furthermore, the hemispheroid, the bulge and the bolt head are integrally formed.
Furthermore, the guide rod and the screw rod are integrally formed.
Furthermore, the pull ring is arc-shaped and is not contacted with the hexagon socket when being attached to the bolt head.
The utility model has the advantages that:
1. the utility model is provided with the corrugated bulges, can effectively prevent looseness, can buffer impact, and has good elasticity, impact resistance and other performances;
2. when the bolt head of the utility model is disassembled and assembled, one of the inner hexagonal wrench and the outer hexagonal wrench can be selected, so that the use is more convenient;
3. the bolt head of the utility model is provided with a pull ring, which effectively prevents the slide wire; meanwhile, when no wrench is used, the bolt can be disassembled by inserting a rod into the pull ring to rotate.
Drawings
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic perspective view of the present invention.
In the figure: 1. a bolt head; 2. a screw; 3. a thread; 4. an inner hexagonal hole; 5. a hemisphere; 6. a through hole; 7. a pull ring; 8. a protrusion; 9. a guide bar; 10. and (4) guiding threads.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in fig. 1 in the attached drawings of the specification, an anti-slip thread bolt structure comprises a bolt head 1, wherein a screw 2 is fixedly connected to the lower surface of the bolt head 1, a thread 3 is arranged on the screw 2, a hexagon socket 4 is formed in the center of the bolt head 1, hemispheroids 5 are symmetrically and fixedly connected to two sides of the hexagon socket 4 on the bolt head 1, through holes 6 are formed in the hemispheroids 5, and pull rings 7 are sleeved in the through holes 6;
the lower surface of the bolt head 1 is provided with a circle of bulges 8 at the outer side of the screw rod 2, and the bulges 8 are connected to form a corrugated shape;
one end, far away from the bolt head 1, of the screw rod 2 is provided with a truncated cone-shaped guide rod 9, a guide thread 10 is arranged on the guide rod 9, and the angle of the guide thread 10 is 30-45 degrees.
Furthermore, the hemisphere 5 and the bulge 8 are integrally formed with the bolt head 1.
Further, the guide rod 9 and the screw rod 2 are integrally formed.
Furthermore, the pull ring 7 is arc-shaped and is not contacted with the hexagon socket 4 when being attached to the bolt head 1.
The use principle is as follows:
the anti-slip bolt structure comprises a bolt head 1, a screw rod 2 is fixedly connected to the lower surface of the bolt head 1, threads 3 are arranged on the screw rod 2, a hexagon socket 4 is formed in the center of the bolt head 1, hemispheroids 5 are symmetrically and fixedly connected to the two sides of the hexagon socket 4 on the bolt head 1, through holes 6 are formed in the hemispheroids 5, and pull rings 7 are sleeved in the through holes 6. The pull ring 7 is arc-shaped and is not contacted with the hexagon socket 4 when being attached to the bolt head 1. When the spanner is mounted or dismounted, the pull ring 7 is attached to the bolt head 1, so that the use of the spanner is not hindered. One of an inner hexagonal wrench and an outer hexagonal wrench can be selected, the bolt head 1 is sleeved by the outer hexagonal wrench, the inner hexagonal hole 4 is sleeved by the inner hexagonal wrench, and the use is more convenient; in addition, the pull ring 7 can effectively prevent the screw from slipping, and when a wrench is not used, a rod is inserted into the pull ring 7 to rotate, so that the bolt can be detached.
