DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: a building scaffolding plug-in connection locking member, including a supporting device 3, a positioning device 1 is symmetrically slidably sleeved on the top of the supporting device 3, and a positioning device 2 is fixedly installed on the top of both sides of the supporting device 3. The positioning device 1 includes a supporting pedal 4, an alignment socket 5 and an extension card 6. The alignment socket 5 is symmetrically arranged at the top and side ends of the extension card 6, and the extension card 6 is fixedly installed at both ends of the supporting pedal 4. The supporting device 3 includes a supporting top frame 13, an alignment groove 14, a scaffold 15 and a protrusion 16. The protrusion 16 is symmetrically fixedly installed on the top of the supporting top frame 13, the supporting top frame 13 is fixedly installed on the top two ends of the scaffold 15, and the alignment groove 14 is symmetrically arranged on the outside of the supporting top frame 13.

[0021] The positioning device 2 includes a reset spring 7, an alignment rod 8, a connecting plate 9, a supporting substrate 10, a handle 11 and a positioning cavity 12. The handle 11 is symmetrically slidably inserted into the outside of the positioning cavity 12. The connecting plate 9 is fixedly installed at one end of the handle 11. The alignment rod 8 is fixedly installed on the side end of the connecting plate 9 away from the handle 11. The reset spring 7 is symmetrically fixedly installed between the connecting plate 9 and the positioning cavity 12. The positioning cavity 12 is fixedly installed on the top of the supporting substrate 10.

[0022] The support base plate 10 is fixedly mounted on the top ends of both sides of the scaffolding 15 , and the extended clamping plate 6 is slidably sleeved on the top end of the support top frame 13 , which can facilitate the docking of the support pedal 4 with the support top frame 13 .

[0023] The bottom of the side end of the extension card plate 6 away from the support pedal 4 is inclined at 45 degrees, so as to improve the smoothness of the extension card plate 6 when passing through the alignment rod 8.

[0024] The alignment socket 5, alignment rod 8, alignment groove 14 and protrusion 16 are all vertically aligned to improve the installation accuracy of the support pedal 4. The alignment rod 8 is arranged in an arc state away from the top of the side end of the handle 11, so that the smoothness of the extended card 6 passing through the alignment rod 8 can be improved.

[0025] The interior of the positioning cavity 12 is hollow, and a connecting rod is fixedly installed at one end of the handle 11 close to the alignment rod 8. When the handle 11 moves, the connecting rod can drive the connecting plate 9 and the alignment rod 8 to move.

[0026] Working principle: When in use, first assemble the scaffolding 15, then move the scaffolding 15 as a whole to the designated working area, then move the support pedal 4 to the top of the support top frame 13, and then move the support pedal 4 downward until the alignment socket 5 is slidably sleeved on the protrusion 16, thereby preventing the support pedal 4 from being skewed. Afterwards, when the support pedal 4 continues to move downward to the limit position, it can drive the extension card 6 to completely pass through the alignment plug rod 8, and the bottom of the side end of the extension card 6 away from the support pedal 4 is 4 The 5° tilt setting can improve the smoothness of the extended card plate 6 passing through the alignment rod 8. Subsequently, when the support pedal 4 is installed in place, the alignment rod 8 can be vertically aligned with the alignment hole 5 at the side end of the extended card plate 6 away from the support pedal 4. At this time, the elasticity of the reset spring 7 will drive the alignment rod 8 to quickly insert into the alignment hole 5 inside the side end of the extended card plate 6, thereby limiting the positioning of the extended card plate 6 and preventing the extended card plate 6 from falling off again. Moreover, when the alignment rod 8 is completely reset, it can penetrate the extended card plate The alignment socket 5 inside the side end of 6 enters the alignment groove 14, so that the limiting strength of the extension card plate 6 can be improved to complete the installation and positioning of the support pedal 4. Subsequently, when the support pedal 4 needs to be removed, the handle 11 can be pulled outward, so that the connecting plate 9 and the alignment plug rod 8 can be driven to move into the positioning cavity 12 until the alignment plug rod 8 and the alignment socket 5 inside the side end of the extension card plate 6 are removed, and then the support pedal 4 is pulled upward as a whole, so that the support pedal 4 can be moved out from the top of the scaffold 15 to complete the installation and positioning of the support pedal 4. During the disassembly of the support pedal 4, the present device drives the alignment socket 5 to quickly dock and match the protrusion 16 and the alignment rod 8 through the extended card plate 6, so that the alignment rod 8 and the protrusion 16 can limit the extended card plate 6, thereby preventing the support pedal 4 from falling off when the construction workers step on it. Moreover, when the support pedal 4 needs to be removed, the handle 11 can be pulled outward to drive the alignment rod 8 to move out from the inside of the extended card plate 6, thereby releasing the support pedal 4, making it easy to disassemble the support pedal 4 and complete the work.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
