Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1 to 4 This utility model relates to a connection mechanism for a building space frame, comprising a transition component 1 and six connecting components 2. The transition component 1 includes a base section 101 and six transition sleeves 102. By rotating and installing the transition sleeves 102 on the six faces of the base section 101 in the transition component 1, and installing the connecting components 2 on each transition sleeve 102, the rods are fixedly installed on the connecting components 2. By rotating the transition sleeves 102, the angles between the connecting components 2 can be adjusted so that the angles between the rods connected to the base section 1 meet the design requirements. By adjusting the length of the connecting arm 202 in the connecting component 2, the rods connected to the connecting arm 202 can be finely adjusted according to the design of the space frame, thereby eliminating errors that occur during rod connection, eliminating the need to adjust the length of the rods, and improving construction efficiency.

[0029] Specifically, the base 101 is a cube structure, with six adapter shafts 101a fixed on each of the six faces of the base 101, six adapter sleeves 102 rotatably mounted on the six adapter shafts 101a, and six connecting components 2 rotatably mounted inside the six adapter sleeves 102.

[0030] Furthermore, the connecting assembly 2 includes a universal joint sleeve 201 and a connecting arm 202. The universal joint sleeve 201 is connected to the end of the adapter sleeve 102 away from the adapter shaft 101a via a hinge structure, and the connecting arm 202 is installed at the end of the universal joint sleeve 201 away from the adapter sleeve 102.

[0031] Furthermore, a junction welding plate 101a-1 is fixedly provided on the outer side of one end of the adapter shaft 101a near the base junction 101, and an adapter sleeve welding plate 102a is fixedly provided on one end of the adapter sleeve 102 near the adapter shaft 101a. The joint between the junction welding plate 101a-1 and the adapter sleeve welding plate 102a has a longer welding length, making the weld between the adapter sleeve 102 and the base junction 101 more robust.

[0032] Furthermore, a top sleeve 201b is fixed at one end of the universal joint sleeve 201 away from the adapter sleeve 102, and a connecting sleeve 201c is fixed at one end of the top sleeve 201b away from the universal joint sleeve 201. The connecting sleeve 201c is used to install the connecting arm 202.

[0033] Furthermore, the connecting sleeve 201c has a thread inside, and the connecting arm 202 has a thread on the outside, and the connecting arm 202 is threadedly connected to the connecting sleeve 201c.

[0034] Furthermore, a compression spring 201a is fixedly connected to the top surface of the top sleeve 201b. The end of the compression spring 201a away from the universal joint sleeve 201 is pressed against the end face of the connecting arm 202 near the universal joint sleeve 201. The compression spring 201a presses the connecting arm 202 tightly to prevent the connecting arm 202 from loosening inside the connecting sleeve 201c.

[0035] The operation process in this embodiment is as follows:

[0036] Install each rod threadedly into the connecting arm 202, adjust the angles of the universal joint sleeve 201 and the adapter sleeve 102 so that the connection angle between the rod and each base joint seat 101 conforms to the design of the space frame, weld the joint seat welding plate 101a-1 and the adapter sleeve welding plate 102a, and weld the universal joint sleeve 201 and the adapter sleeve 102 to fix the angle between each base joint seat 101 and the rod, install the rod into the connecting arm 202, and adjust the length of the connecting arm 202 extending into the connecting sleeve 201c according to the design of the space frame to compensate for the length deviation of the rod during connection.

[0037] Example 2

[0038] Please seeFigures 1 to 5 Based on embodiment 1, a mating sleeve 202a is fixedly provided on the connecting arm 202. By threading the rod into the mating sleeve 202a and welding the rod to the mating sleeve 202a, the rod is fixedly connected to the base section seat 101.

[0039] Specifically, a mating sleeve 202a is fixed at the end of the connecting arm 202 away from the universal joint sleeve 101, and the mating sleeve 202a has an internal thread.

[0040] Furthermore, a set of welding notches 202a-1 are circumferentially arrayed on the side wall of the mating sleeve 202a. The length direction of the welding notches 202a-1 is parallel to the cylindrical axis of the mating sleeve 202a. The welding notches 202a-1 gradually expand outward from the internal thread, making the weld length between the rod and the mating sleeve 202a longer and the weld between the rod and the mating sleeve 202a more secure.

[0041] The operation process in this embodiment is as follows:

[0042] The rod is threaded into the mating sleeve 202a, and the welding notch 202a-1 is welded to the rod to fix the rod to the connecting arm 202.
