Abstract
The invention discloses a bolt capable of reducing looseness, which comprises a regular hexagonal prism-shaped end part and a cylindrical column part, wherein a regular hexagonal sliding body is arranged on the end part in a sliding mode. The invention has the following advantages and effects: through setting up the sliding body, can make regular hexagonal shape hole on the work piece to the cooperation between bolt and the nut produce stable limiting displacement to avoid the not hard up problem of cooperation between bolt and the nut that causes because reasons such as vibrations, guarantee the security of equipment operation.
Description
Technical Field
The invention relates to the technical field of fasteners, in particular to a bolt capable of reducing looseness.
Background
Bolts and nuts are used as conventional fasteners, usually in conjunction to secure the parts to be fastened.
But the cooperation of bolt and nut after long-term use, easily produce to become flexible, especially when using on the great equipment of vibrations, more easily produce to become flexible and need frequent maintenance to guarantee the stability of equipment. However, when the bolt and nut matching structure is installed in some large-scale equipment, the bolt and nut matching structure at the inner part is difficult to overhaul, so that the running safety of the equipment is affected.
Disclosure of Invention
The invention aims to provide a bolt capable of reducing looseness.
The technical purpose of the invention is realized by the following technical scheme: the bolt capable of reducing looseness comprises a regular hexagonal prism-shaped end part and a cylindrical column part, and a regular hexagonal sliding body is arranged on the end part in a sliding mode.
Further setting the following steps: the thickness of the slider body is 1/2 the thickness of the end portion.
Further setting the following steps: the outer surface of the end part is provided with at least two sliding grooves, and the inner wall of the sliding body is provided with a sliding rod extending to the sliding grooves.
Further setting as follows: the top of tip is provided with the open slot, is provided with horizontal perforating hole on the inner wall of open slot, is provided with the gag lever post in the perforating hole, is provided with compression spring in the open slot, and compression spring's one end is supported in the inboard one end of gag lever post.
Further setting as follows: the through-hole includes two and relative setting.
Further setting the following steps: the open slot is in the shape of a regular hexagon prism.
In conclusion, the invention has the following beneficial effects: through setting up the sliding body, can make regular hexagonal shape hole on the work piece produce stable limiting displacement to the cooperation between bolt and the nut to avoid the not hard up problem of cooperation between bolt and the nut that causes because reasons such as vibrations, guarantee the security of equipment operation.
Drawings
Fig. 1 is a schematic structural view of a bolt.
In the figure: 1. an end portion; 2. a cylindrical portion; 3. a sliding body; 4. a chute; 5. a slide bar; 6. an open slot; 7. a through hole; 8. a limiting rod; 9. a compression spring; 10. and a nut.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The bolt capable of reducing looseness comprises a cylindrical column part and an end part positioned at one end of the column part, wherein the end part is in a regular hexagonal prism shape. The column part is provided with threads and is matched with the nut to fix a required workpiece when in use.
Two opposite surfaces of the end part are respectively provided with a sliding groove, a sliding body is arranged outside the end part, the inside of the sliding body is communicated, the communicated part is in a regular hexagon shape, and the inner wall of the communicated part is attached to the outer wall of the end part. The sliding rod embedded into the sliding groove is arranged on the inner wall of the sliding body, so that the sliding body can be limited, and the sliding body is prevented from being separated from the end part.
The thickness of the sliding body is 1/2 of the end thickness, and the bolt is matched with a regular hexagonal hole on a workpiece to be used when in use. After the bolt is inserted, the end of the column is connected with the nut. The nut is directly embedded into the regular hexagonal hole, the sliding body is located at the top of the end portion, and the sliding body of the bolt is screwed by a tool, so that the workpiece can be fastened. Meanwhile, the lower end face of the end part is sunk into the regular hexagonal hole. After the lower end face of the end part sinks into the regular prismatic hole, the sliding body is shifted towards the lower end face of the end part, the outer wall of the sliding body can be attached to the inner wall of the regular hexagonal hole, and therefore the situation that the bolt and the nut are loosened during vibration is avoided.
The top end of the end part is provided with an open slot, and the section of the open slot can be arranged to be a regular hexagon for increasing the applicability. The inner wall of the open slot is provided with two opposite through holes, the through holes are internally provided with a limiting rod, the inner end of the limiting rod is larger in section so as to avoid the limiting rod from being separated from the through holes, a compression spring is arranged between the opposite ends of the two limiting rods, and the compression spring can push the limiting rod outwards. When the lower end face of the end part sinks into the regular prismatic hole, the sliding body is stirred towards the lower end face of the end part, and then the limiting rod can limit the sliding body, so that the stability of the sliding body is guaranteed.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
