Furthermore, an accommodating cavity is arranged in the bolt column, the accommodating cavity is positioned between two opposite grooves, a capsule filled with glue and pressing plates positioned on two sides of the capsule are arranged in the accommodating cavity, a first through hole is formed in the surface, opposite to the grooves, of the accommodating cavity, a second through hole opposite to the first through hole is formed in the bottom surface of the groove, a push rod is connected to the pressing plates, and the other end of the push rod penetrates through the first through hole and the second through hole in sequence and then is connected with the right-angle triangular limiting plate; and a flow passage is formed between the outer wall of the plug and the accommodating cavity.
Furthermore, the return spring is sleeved on the push rod.
Furthermore, a limiting bolt is arranged between the right-angle triangular limiting plate and the bottom surface of the groove, and the limiting bolt is made of a hollow fragile material.
Further, the capsule is made of a plastic film.
Furthermore, glue is coated on the bottom surface of the bolt cap.
Furthermore, the outlet of the flow channel is positioned at the thread of the outer wall of the bolt column, and a plurality of inlets of the flow channel are respectively arranged at the top, the bottom and the middle of the accommodating cavity.
The invention has the advantages that:
1. the fastening glue is simple to glue, the bolt can be fastened and glued only by normally screwing the bolt, the harm to hands is avoided, and the glue cannot drip outside the screw hole;
2. the glue is uniformly coated, and the pressing plate slowly extrudes the capsule in the screwing process of the bolt, so that the glue is slowly extruded out and automatically coated along with the rotation of the bolt;
3. the right-angle triangular limiting plate is matched with the glue to achieve double fastening of the bolt, so that the fastening effect of the bolt is greatly improved;
4. when leaving the factory, glue is stored in the bolt, and the reduction of glue can not be caused due to packaging and transportation vibration.

description of the reference symbols
The capsule comprises a bolt cap 1, a bolt column 2, a groove 3, a right-angle triangular limiting plate 4, a return spring 5, a containing cavity 6, a capsule 7, a push rod 8, a pressing plate 9, a flow channel 10, glue 11 and a limiting bolt 12.
Detailed Description
The present invention will be described in further detail with reference to examples.
The embodiment provides a locking bolt, as shown in fig. 1 and 2, comprising a bolt cap 1 and a bolt 2 with a thread, wherein 2 pairs of symmetrical grooves 3 are formed on the side wall of the bolt 2, and 2 pairs of grooves 3 are respectively arranged at the upper part and the lower part of the bolt 2. A right-angle triangular limiting plate 4 is arranged in the groove 3, the right-angle end of the right-angle triangular limiting plate 4 faces the bolt cap 1, and the smallest acute-angle end faces the end, far away from the bolt cap 1, of the bolt column 2; be equipped with between 3 bottoms of right angle triangle limiting plate 4 and recess and reply spring 5, when reply spring 5 not compressed, 4 protrusions of right angle triangle limiting plate and the 2 lateral walls of embolus, when reply spring 5 was compressed, right angle triangle limiting plate 4 got into in the recess 3.
Through the answer spring 5 of chooseing for use suitable elasticity, can avoid right angle triangle limiting plate 4 to be pushed in because of exogenic action in packing or transportation, for further restriction right angle triangle limiting plate 4 takes place the maloperation under the exogenic action, this embodiment is equipped with spacing bolt 12 between right angle triangle limiting plate 4 and 3 bottoms surfaces of recess, spacing bolt 12 adopts hollow breakable material to make.
When the capsule compression device is used, a bolt is gradually screwed into a bolt hole by a wrench or a screwdriver, under the thrust action of the bolt hole, the right-angle triangular limiting plate 4 firstly crushes the limiting bolt 12 at the initial moving stage, and then is slowly pressed into the groove 3, so that the capsule 7 is compressed by the push rod 8 and the pressing plate 9. When the capsule 7 is compressed to a certain degree, the capsule 7 is broken, the glue in the capsule 7 flows out and flows to the thread position of the outer wall of the plug 2 through the flow passage 10, and the gluing is realized. After the bolt hole was twisted completely to the bolt, glue accomplished the solidification through the reaction of certain time, and simultaneously, right angle triangle limiting plate 4 can be outwards supported the bolt hole inner wall under the effect of answer spring 5, improves the frictional force between bolt and the bolt hole to locking effect has been improved.
Because the bolt can be horizontally placed, and can also be installed or inverted (the bolt cap 1 is upright when facing upwards, and is inverted when facing downwards), in order to facilitate the glue to flow into the flow channel 10, the outlet of the flow channel 10 in this embodiment is located at the thread of the outer wall of the bolt post 2, and a plurality of inlets of the flow channel 10 are respectively arranged at the top, the bottom and the middle of the accommodating cavity 6.
In order to further improve the anti-loosening degree of the bolt, glue is applied to the bottom surface of the bolt cap 1 in a spot mode, and the glue is attached to the bolt through machine glue dispensing.
The glue in the embodiment refers to fastening glue special for metal.
The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
