The outer side wall of the support ring 52 is provided with a transmission groove 521 along the axial direction, the transmission key 32 can move along the axial direction of the transmission groove 521, and when the transmission key 32 is positioned in the transmission groove 521, the rotation of the fixed ring 3 can drive the limit ring 5 and the support ring 52 to synchronously rotate.
Referring to fig. 7, 8, 9, 10 and 11, the sliding key 24 is fixedly connected to the outer side wall of the plugging rod 2, the connecting pipe 6 is slidably sleeved on the outer side wall of the plugging rod 2, the sliding groove 64 is formed in the inner side wall of the connecting pipe 6, the sliding key 24 can move along the axial direction of the sliding groove 64, and therefore the connecting pipe 6 can move along the axial direction of the plugging rod 2. The inner side wall of the connecting pipe 6 is fixedly connected with a limiting tooth 61 which can be meshed with the limiting groove 51. The spacing tooth 61 sets up the both ends at connecting pipe 6, and support ring 52, grafting pole 2, bracing piece 1 and solid fixed ring 3 all are provided with two, and two support rings 52, grafting pole 2, bracing piece 1 and solid fixed ring 3 set up respectively at the both ends of connecting pipe 6.
When the fastening block 31 is separated from the fastening key 11, the fixed ring 3 rotates to drive the transmission key 32 to rotate around the central axis of the insertion rod 2, the transmission key 32 abuts against the side wall of the transmission groove 521 to drive the support ring 52 to rotate, and the limit groove 51 and the support ring 52 synchronously rotate, so that the limit groove 51 is separated from the limit teeth 61 (refer to fig. 12). Then the connecting pipe 6 is moved along the axial direction, the relative distance between the connecting pipe 6 and the limiting ring 5 is adjusted, because the limiting ring 5 can not move along the axial direction relative to the inserting connection rod 2, and the inserting connection rod 2 is fixed on the supporting rod 1, thereby adjusting the distance between the supporting rings 52 on two sides of the connecting pipe 6 according to the distance between the supporting rods 1 on two sides of the connecting pipe 6, reducing the deformation of the connecting pipe 6 and the supporting rod 1, and reducing the negative influence of the deformation of parts on the supporting effect of the support of the building steel pipe.
When the position of the supporting ring 52 is adjusted, the fixed ring 3 rotates to drive the supporting ring 52 to reversely rotate through the transmission key 32 and the transmission groove 521, and the limiting groove 51 and the supporting ring 52 synchronously rotate to be engaged with the limiting teeth 61, so that the movement of the supporting ring 52 relative to the connecting pipe 6 is limited.
Referring to fig. 7, 8 and 11, the outer side wall of the plugging rod 2 is fixedly connected with a snap ring 23, and the inner side wall of the supporting ring 52 is provided with a clamping groove 522 capable of being matched with the snap ring 23, so that the supporting ring 52 can rotate around the central axis of the plugging rod 2.

Since the insertion rod 2 is fixed to the support rod 1 at this time, the insertion rod 2 restricts the rotation of the support ring 52 by the first slide groove 221, the transmission key 32, and the transmission groove 521, thereby locking the engagement of the stopper teeth 61 with the stopper groove 51. When the fixing ring 3 drives the fastening block 31 to move away from the supporting rod 1, so that the fastening block 31 is separated from the fastening key 11, the transmission key 32 moves synchronously with the fixing ring 3 to separate from the first sliding groove 221, and at this time, the fixing ring 3 can rotate around the plugging rod 2, so that the fixing ring 3 can drive the supporting ring 52 to rotate, and the limiting teeth 61 can be separated from the limiting grooves 51.

When the limiting teeth 61 are separated from the limiting grooves 51, the first extruding springs 54 can extrude the connecting pipe 6 according to the distance between the supporting rods 1 on two sides of the connecting pipe 6, and then the relative distance between the connecting pipe 6 and the supporting ring 52 can be adaptively adjusted.
Referring to fig. 2 and 4, the side wall of the fixed ring 3 is provided with the locking hole 34, when the fastening block 31 is separated from the fastening key 11 and the limiting teeth 61 are separated from the limiting groove 51, the fixed ring 3 rotates around the inserting connection rod 2 to enable the limiting rod 4 to enter the locking hole 34, so that the separation state of the limiting teeth 61 and the limiting groove 51 can be maintained, and the adverse effect of irregular rotation of the supporting ring 52 on the adjustment distance between the supporting ring 52 and the connecting pipe 6 is reduced.
The implementation principle of the socket type key groove type building steel pipe support structure of the embodiment of the invention is as follows: when a constructor installs the building steel pipe support, firstly, the support rod 1 is vertically fixed, and the key groove 21 of the inserting connection rod 2 is matched with the fastening key 11 to be inserted and fixed.
