DETAILED DESCRIPTION

[0019] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0020] A tapered pin structure that facilitates centering and disassembly of a steel frame, comprising a steel member 1, a steel member 2, and a connecting structure connecting the steel member 1 and the steel member 2;

[0021] A through hole 101 is formed along the thickness direction of the steel member 1, and a through hole 201 is formed along the thickness direction of the steel member 2;

[0022] The connection structure includes a double-headed tapered pin 3, a first tapered pin sleeve 4 and a second tapered pin sleeve 5 sleeved on both ends of the double-headed tapered pin 3, and a first fixing nut 6 and a second fixing nut 7 screwed and fixed to the ends of the double-headed tapered pin 3;

[0023] The outer surface of the double-headed tapered pin 3 is provided with a first tapered surface 301 and a second tapered surface 302 which are symmetrical along the middle part of its length direction. The axial center position of the first tapered pin sleeve 4 is provided with a first tapered through hole 401 which matches the first tapered surface 301, and the axial center position of the second tapered pin sleeve 5 is provided with a second tapered through hole 501 which matches the second tapered surface 302.

[0024] In the technical solution of the connection structure of the present invention, the connection structure consists of a double-headed tapered pin 3, a tapered pin sleeve and a fixing nut. When in use, the steel component 1 and the steel component 2 are arranged in parallel, the first tapered pin sleeve 4 is inserted into the through hole 101 from the outer end face of the steel component 1, and the second tapered pin sleeve 5 is inserted into the through hole 201 from the outer end face of the steel component 2. The double-headed tapered pin 3 is arranged between the steel component 1 and the steel component 2, and its two ends extend into the through hole 101 and the through hole 201 respectively. The first threaded section 303 of the double-headed tapered pin 3 extends from the other side through the steel component 1 and is fixed by the first fixing nut 6. The second threaded section 304 of the double-headed tapered pin 3 extends from the other side through the steel component 2 and is fixed by the second fixing nut 7.

[0025] It should be noted that a through hole 101 is provided along the thickness direction of the steel component 1, and a through hole 201 is provided along the thickness direction of the steel component 2. The through hole 101 is consistent with the shape of the first taper pin sleeve 4, and the through hole 201 is consistent with the shape of the second taper pin sleeve 5. Considering adaptability, generally speaking, the through hole 101 is consistent with the shape of the through hole 201.

[0026] In the technical solution of the tapered pin sleeve and the through hole of the present invention, an annular groove 102 is provided on the outer edge of the through hole 101 at the end surface of the steel component 1 facing away from the steel component 2 2, and an annular groove 202 is provided on the outer edge of the through hole 2 201 at the end surface of the steel component 2 2 facing away from the steel component 1 .

[0027] Furthermore, in the above solution, an annular protrusion 402 is provided at any end of the first tapered pin sleeve 4 , and the annular protrusion 402 is provided around the outer surface of the first tapered pin sleeve 4 and is integrally formed with the first tapered pin sleeve 4 .

[0028] Furthermore, in the above solution, a second annular protrusion 502 is provided at any end of the second tapered pin sleeve 5 , and the second annular protrusion 502 is provided around the outer surface of the second tapered pin sleeve 5 and is integrally formed with the second tapered pin sleeve 5 .

[0029] In a first embodiment of the present utility model, the first taper pin sleeve 4 is directionally inserted into the through hole 101 from the outside of the steel component 1, and the annular protrusion 402 on the first taper pin sleeve 4 matches the annular groove 102 at the end of the through hole 101. The second taper pin sleeve 5 is directionally inserted into the through hole 201 from the outside of the steel component 2, and the annular protrusion 2 502 on the second taper pin sleeve 5 matches the annular groove 202 at the end of the through hole 201. Under the action of the annular groove 102 and the annular groove 202, the outer surfaces of the annular protrusion 402 and the annular protrusion 2 502 are flush with the outer surface of the steel component, and the overall appearance is more beautiful. The embedded annular groove 102 and the annular groove 202 have a concealing effect on the annular protrusion to prevent scratches during assembly.

[0030] In a second embodiment of the present utility model, a through hole 101 is provided along the thickness direction of the steel component 1, and a through hole 201 is provided along the thickness direction of the steel component 2. The end of the first taper pin sleeve 4 is provided with an annular protrusion 402, and the end of the second taper pin sleeve 5 is provided with an annular protrusion 502. When the first taper pin sleeve 4 is inserted into the through hole 101, the annular protrusion 402 is affixed to the outer surface of the steel component 1. When the first taper pin sleeve 4 is inserted into the through hole 201, the annular protrusion 502 is affixed to the outer surface of the steel component 1. The difference from the technical solution of the first embodiment is that the steel component 1 and the steel component 2 are not provided with embedded annular grooves. When disassembling, the taper pin sleeve 1 and the taper pin sleeve 2 are more likely to fall off from the steel component.

[0031] As an improvement to the above scheme, the two ends of the double-headed tapered pin 3 are respectively provided with a first thread segment 303 and a second thread segment 304, the first thread segment 303 extends outward along the first conical through hole 401 and is screwed and fixed with the first fixing nut 6, and the second thread segment 304 extends outward along the second conical through hole 501 and is screwed and fixed with the second fixing nut 7.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
