Description of reference numerals:
the bolt comprises a rubber part 1, an elastic clamping piece 1-1, a thread ring 1-2, a caulking groove 1-3, a side hole 1-4, a connecting iron pin 2, a rod body 2-1, a fastening connector 2-2 and a key groove 2-3.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 5, the technical solution adopted by the present embodiment is: the rubber part comprises a rubber part 1 and a connecting iron pin 2, wherein the total length of the connecting iron pin 2 is twice that of the rubber part 1; the rubber part 1 is of a hollow structure, a spring clamping piece 1-1 is arranged on the inner side wall of the rubber part 1, a threaded ring 1-2 is arranged on the outer ring surface of one end of the rubber part 1, a caulking groove 1-3 is arranged inside the left end of the rubber part 1, and a side hole 1-4 is formed in the side surface of the rubber part 1; the rubber part 1, the spring clamping piece 1-1 and the thread ring 1-2 are of an injection molding integrated forming structure, the two ends of the connecting iron pin 2 are connected with the rubber part 1, the two ends of the rod body 2-1 of the connecting iron pin 2 are provided with fastening connectors 2-2, the rod body 2-1 and the fastening connectors 2-2 are of an integral structure, the fastening connectors 2-2 on the left side and the right side are respectively inserted into the rubber part 1 on the left side and the right side of the rod body 2-1, the edges of the left side and the right side of the rod body 2-1 are provided with chamfers, the connecting parts of the fastening connectors 2-2 and the rod body 2-1 are provided with key grooves 2-3, and the key grooves 2-3 are clamped in the spring clamping piece 1-1.
The working principle of the specific embodiment is as follows: firstly, two wood boards to be connected are punched according to positioning, a group of connecting pieces are composed of two identical rubber pieces 1 and a connecting iron pin 2, the two rubber pieces 1 are respectively pressed into drill holes formed in the two wood boards, the left end of each rubber piece 1 is an insertion end, a thread ring 1-2 at the left end is pressed into each drill hole under the action of external force, a side hole 1-4 at the outer side of each thread ring 1-2 is extruded and contracted so as to be convenient to install, after the rubber pieces 1 are completely pressed into the drill holes, the side holes 1-4 lose extrusion force and recover to an initial state under the action of elastic force, so that the thread rings 1-2 are in contact with the inner wall of the drill holes, the rubber pieces 1 can be firmly fixed in the drill holes and are not easy to fall off, then one end of the connecting iron pin 2 is knocked into the rubber pieces 1 through a hammer, and a fastening connector 2-2 enters an embedding groove 1-3 in the rubber pieces 1, the key groove 2-3 is clamped in the elastic clamping piece 1-1 positioned in the rubber piece 1, the fastening connector 2-2 is limited and fixed by the elastic clamping piece 1-1 to prevent the elastic clamping piece 1 from being separated, and then the other end of the connecting iron pin 2 is knocked into the rubber piece 1 in another wood board, so that the two boards are fixedly connected.
