The embodiment of the utility model is shown in figures 1-4, and the socket type disc buckle scaffold comprises a vertical rod 1, a cross rod 2 and a bolt 3, wherein a connecting disc 4 is arranged on the vertical rod 1, a plurality of jacks 41 are arranged on the connecting disc 4, connectors 5 are arranged at two ends of the cross rod 2, pin holes 51 are arranged on the connectors 5, and the jacks 41 are connected with the pin holes 51 through the bolts 3. On the basis, the bolt 3 provided by the utility model comprises a big head end 31, a splicing section 32, a transition section 33 and a hanging section 34 which are integrally connected from top to bottom, the longitudinal section of a connector 5 is in an F shape, the opening of the connector is used for being spliced with a connecting disc 4, the edge of the top surface of the connector 5 is provided with a notch 52 matched with the big head end 31, two corner ribs 53 are arranged at two ends of the inner side of the connector 5 near the bottom of the connector, two clamping springs 6 are rotatably arranged on the two corner ribs 53, each clamping spring 6 comprises two spring feet 63, each spring foot 63 is matched with clamping grooves 35 arranged at two sides of the hanging section 34, two countersunk holes 54 symmetrically distributed about the pin holes 51 are arranged at the top of the connector 5, an inner hexagon bolt 7 is arranged in each countersunk hole 54, and the bottom of the inner hexagon bolt 7 is in contact fit with a self-locking groove 42 arranged on the connecting disc 4.

Specifically, the pin 3 is inserted into the pin hole 51 and the jack 41 from top to bottom, the big end 31 of the pin can be clamped with the notch 52, the pin 3 is prevented from swinging, and the stability of the pin 3 on the connecting disc 4 and the connecting head 5 is improved. The clamping grooves 35 on the two sides of the bolt 3 can be movably clamped with the clamping springs 6, for example, the spacing between the two spring feet 63 of the clamping springs 6 is smaller in a free state, and the clamping pins can be matched with the clamping grooves 35 after being spread and clamped into the clamping grooves 35, and certain elastic pressure is maintained; the clamp spring 6 can be opened by manual or auxiliary instruments to unlock the bolt 3; after the inner hexagon bolt 7 is matched with the self-locking groove 42, the connector 5 and the connecting disc 4 can be prevented from generating larger radial displacement, so that the matching performance of the clamping groove 35 and the clamping spring 6 is improved, and the connection reliability of the connecting disc 4 and the connector 5 is improved. The fit tightness degree of the clamping groove 35 and the clamping spring 6 is moderate under the fit of the inner hexagon bolt 7 and the self-locking groove 42, so that the clamping purpose can be achieved and the separation is convenient.

In order to improve the utilization rate of the device, the self-locking groove 42 designed on the connecting disc 4 gradually becomes shallow from one end close to the upright 1 to the edge of the connecting disc 4. In this way, the socket head cap screw 7 can be always installed in the counter bore 54, and only the actual sinking position of the bottom of the socket head cap screw is required to be finely adjusted in the use process; if the connecting disc 4 and the connecting head 5 are in a non-connection state, the bottom of the inner hexagon bolt 7 extends out of the mouth end of the F-shaped mouth for a certain distance; in the process of inserting and matching the connector 5 towards the connecting disc 4, the connector 5 and the cross rod 2 can be lifted slightly, the inner hexagon bolt 7 slides along the direction of the self-locking groove 42, the F-shaped opening of the connector 5 is bitten on the connecting disc 4 and moves towards the center direction of the vertical rod 1 until the connector 5 and the connecting disc 4 are completely inserted, the limit effect can be achieved by screwing the inner hexagon bolt 7 for a few circles, reasonable radial activity allowance is reserved for the connector 5 and the connecting disc 4, larger displacement is not generated, and the connection reliability of the device is guaranteed.
