the connecting portion 12 is provided with a first mounting hole 122, the end portion of the connecting rod 2 is provided with a second mounting hole 22, and the positioning member is inserted into the first mounting hole 122 and the second mounting hole 22 to connect the connecting rod 2 and the connecting portion 12.
The utility model discloses a tubular product connection structure utilizes the gomphosis, setting element and the multiple fixed of cooperation of first mounting hole and second mounting hole of cup jointing, arch and recess of connecting rod and connecting portion connecting rod and connecting piece make the connection stability of connecting piece and connecting rod better. Dismantle the utility model discloses a during tubular product connection structure, only need remove the setting element can separate connecting piece and connecting rod, the operation of being convenient for.
The positioning piece is a screw and comprises a threaded part and a nut; the outer surface of the connecting rod 2 is provided with a sinking platform 21, and the sinking platform 21 is formed by sinking the outer surface of the connecting rod 2 to the inner surface; the sink 21 is used to accommodate the nut. After the positioning piece is screwed down, the nut of the positioning piece is positioned in the sinking platform 21 and cannot protrude out of the surface of the connecting rod 2, so that the nut is prevented from protruding to scratch and obstruct the installation of other parts of the cabinet body, and meanwhile, the appearance of the cabinet body is more attractive.
To facilitate the insertion of the connector 1 and the connector rod 2, the recess 121 is open towards the end of the connecting portion 12. When the user assembles the connecting member 1 and the connecting rod 2, the relative positions of the first mounting hole 122 and the second mounting hole 22 in the circumferential direction can be restricted by aligning the sinking platform 21 with the groove 121 and pushing the connecting portion 12 into the connecting rod 2.
Further, the groove 121 includes a head 1211 and a tail end 1212, and the head 1211 is formed by opening the end of the groove 121 toward the connecting portion 12; when the first mounting hole 122 faces the second mounting hole 22, the end 1212 of the groove 121 abuts against the sinking platform 21. Therefore, when the sinking platform 21 is pushed to the groove end 1212, the first mounting hole 122 just faces the second mounting hole 22. The cooperation of heavy platform 21 and recess 121, can connecting portion 12 and the guide structure of connecting rod 2 grafting can regard as the prepositioning structure of first mounting hole 122 and second mounting hole 22 again, and convenience of customers installs the setting element.
The connecting part 12 is integrally cylindrical, and the connecting rod 2 is a circular hollow pipe. Because the groove 121 and the sinking platform 21 are used as guiding and positioning structures, the requirement on the dimensional accuracy of the outer surface and the inner surface of the connecting part 12 can be reduced by adopting cambered surfaces as the matching surfaces of the connecting part 12 and the connecting rod 2.
The central element 11 is a circular tube, and a partition plate with holes is arranged in the circular tube; the connecting rod 2 is in a plug-in fit with the end of the central element 11. Since the connecting rod 2 is a circular hollow tube, it can be directly fitted with the central element 11 without additional fittings. Under the action of gravity and pressure, the central element 11 is in sleeve fit with the connecting pipe to achieve the fastening effect.
The connecting portions 12 are circumferentially distributed along the central element 11, and the included angle between the axes of two adjacent connecting portions 12 is 90 degrees or 180 degrees.
As shown in fig. 1, two connecting portions 12 are connected to the central member 11, the axes of the two connecting portions 12 are perpendicular to each other, and the connecting member 1 is suitable for a double-rod connecting structure in the same horizontal plane.
As shown in fig. 3, the central element 11 is connected with three connecting portions 12, two connecting portions 12 are arranged oppositely, and the other connecting portion 12 is arranged between the two connecting portions 12, so that the connecting piece 1 is suitable for a three-rod connecting structure in the same horizontal plane.
As shown in fig. 4, four connecting portions 12 are connected to the central member 11, the four connecting portions 12 are evenly distributed along the circumference of the central member 11, and the connector 1 is suitable for a four-bar linkage structure in the same horizontal plane.
As shown in fig. 5, the connecting rod 2 is provided at a central portion thereof with a plurality of plate body connecting holes 23 distributed along the circumferential direction, and the interval between two adjacent plate body connecting holes 23 is 90 ° or 180 °. In practical application, a preset hole is formed in the plate body for forming the cabinet body, the preset hole corresponds to the plate body connecting hole 23, so that the locking piece can penetrate through the plate body connecting hole 23 and the preset hole, and the plate body is fixed on the connecting rod 2.
The utility model discloses still provide the cabinet body, as shown in fig. 6, the cabinet body has above-mentioned connecting piece 1 and connecting rod 2, wherein connecting rod 2 is connected with on at least one tip connecting piece 1, one be connected with two at least on the connecting piece 1 connecting rod 2.
