DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figures 1 to 6The utility model provides a technical solution: a quick-detachable T-bolt embedded part, including an embedded T-bolt 1 and an embedded bolt connector 2, the embedded T-bolt 1 includes a stud 11 and a bolt head 12, the stud 11 is provided with a hexagonal nut 3 connected by a thread, the embedded bolt connector 2 includes an outer ring 21 and an inner ring 22, the outer ring 21 is provided with a bolt hole 211 in the middle, the outer ring 21 is provided with an outer fixed arc groove 212 around the periphery, and the inner ring 22 is provided with a The bolt self-locking hole 221, the inner ring 22 is provided with an inner fixed arc groove 222 and an inner connecting arc groove 223 around the periphery, the material of the embedded bolt connector 2 is metal iron, the embedded bolt connector 2 can be integrally cast, or it can be formed by wire cutting to separately process the outer ring 21 and the inner ring 22, and then align the outer fixed arc groove 212 with the inner fixed arc groove 222 and weld them together, wherein the welding point is arranged inside the inner connecting arc groove 223, and the embedded bolt connector is installed. When connecting the parts 2, firstly a circular slot hole is opened on the steel plate, and then the embedded bolt connector 2 is inserted into the slot hole and fixedly connected by welding with the outer ring 21 facing outward, wherein the welding point is arranged in the slot hole formed by the outer fixed arc groove 212 and the inner fixed arc groove 222, the cross section of the bolt head 12 is an unequal side hexagon with a length dimension greater than a width dimension, the shape and size of the through bolt hole 211 are the same as the shape and size of the bolt head 12, and the bolt head 12 can pass through the through bolt hole 211 to enter the bolt In the self-locking hole 221, the thickness of the bolt head 12 is equal to or less than the depth of the bolt self-locking hole 221. The bolt head 12 can rotate in one direction and is blocked by the inner side of the bolt self-locking hole 221 after rotating 90°. At this time, the long side of the bolt head 12 is stuck under the outer ring 21, so that the embedded T-bolt 1 cannot be pulled out from the embedded bolt connector 2. The hexagonal nut 3 is a flange anti-loosening nut. When the hexagonal nut 3 is tightened toward the root of the stud 11, the embedded T-bolt 1 and the embedded bolt connector 2 can be locked.

[0028] When in use, first make the embedded bolt connector 2 according to the size of the bolts to be installed on the platform, wherein the embedded bolt connector 2 can be integrally cast or can be welded and fixed after the inner and outer rings 21 are processed separately by wire cutting. If it is integrally cast, the inner layer connecting arc groove 223 does not need to be made. If it is welded and spliced, the welding point is set in the inner layer connecting arc groove 223, and the welding point cannot pop out of the inner layer connecting arc groove 223. If it pops out, the side needs to be polished and smoothed, and then the outer surface of the platform is processed into a circular groove by an electric drill. The inner diameter of the groove is The size of the recess is the same as the outer diameter of the embedded bolt connector 2, and the depth of the recess is the same as the thickness of the embedded bolt connector 2. When installing the embedded bolt connector 2, first knock it into the groove with a hammer. In fact, the outer surface of the embedded bolt connector 2 is flush with the outer surface of the platform. The embedded bolt connector 2 is further fixed to the platform by welding, wherein the welding point is set inside the fixed arc groove. At this time, the welding point is hidden inside the fixed arc groove instead of protruding from the outer surface of the platform, so that the surface of the platform remains flat after the embedded part is installed. Since the embedded part is relatively thin, The thickness requirement of the platform is also relatively small, and the platform will not be easily penetrated, and the damage to the platform is very small. In addition, the embedded part is small in size and easy to process. Therefore, it is not only convenient for processing but also has a relatively low processing cost. When it is necessary to install bolts on the platform, first insert the bolt head 12 of the embedded T-bolt 1 into the through-bolt hole 211 and insert it to the bottom, further tighten the hexagonal nut 3 and rotate the embedded T-bolt 1 90° at the same time. At this time, the bolt head 12 of the embedded T-bolt 1 is stuck in the bolt self-locking hole 221. When the hexagonal nut 3 is screwed to the root of the stud 11 and tightened, the embedded T-bolt 1 is It is locked and cannot be rotated. At this time, one side of the embedded T-bolt 1 is fixed on the plane for connecting the external structure. When the embedded T-bolt 1 needs to be removed, it is only necessary to loosen the hexagonal nut 3 and twist the embedded T-bolt 1 to pull it out from the embedded bolt connector 2. Since the twisting angle of the embedded T-bolt 1 during disassembly and assembly is limited by the inner wall of the bolt self-locking hole 221, blind twisting can be achieved to reach the set angle. Therefore, disassembly and assembly are very easy to operate. After removing the embedded T-bolt 1, the embedded bolt connector 2 is still buried inside the platform, and the outer surface of the platform is still flat and beautiful.

[0029] In summary, the quick-detachable T-bolt embedded part can be fixed to the platform welding machine by fixing the arc groove, and it is convenient to install without drilling and tapping. Since the embedded bolt connector 2 is very thin and small and the outer surface is flat, the platform will not be excessively damaged when installing the embedded part, and the outer surface of the embedded bolt connector 2 is flat so that the platform can still remain flat after the embedded part is installed. Since the embedded bolt connector 2 is circular and relatively thin as a whole, only a circular shallow groove needs to be opened during installation, and the opening of the circular groove is very simple, so the embedded part The embedded installation groove is easy to process. During installation, the bolt head 12 of the embedded T-bolt 1 can be easily inserted into the embedded bolt connector 2, and then the embedded T-bolt 1 and the embedded bolt connector 2 can be locked by twisting along the tightening direction of the hexagonal nut 3. During disassembly, the embedded T-bolt 1 can be rotated to an angle that can just be pulled out from the embedded bolt connection by twisting along the loosening direction of the hexagonal nut 3, thereby achieving the effect of rapid disassembly and assembly. Since the embedded bolt connector 2 is small in size and can be cast as one piece or formed by wire cutting, it is easy to process.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
