[0003] After searching, Chinese patent number CN213742235U discloses a flap structure of an all-steel attached lifting scaffolding. By inserting the pin into the slot, the flap can be extended, the flap and the buckle are adjusted to a suitable distance, so that the inside of the fixed grooves at both ends correspond, and then the buckle is fixed to the fixed grooves at both ends of the flap by the steel buckle to achieve the function of fixed installation. The overall pressure resistance of the structure is strong and can carry heavy objects. Through this mechanism, the device can be extended while supporting heavy weight.

[0004] However, when operating the flap structure, it is necessary to fix the flap structure with the pipes of the scaffolding with multiple special connectors, which consumes a lot of materials.

DETAILED DESCRIPTION

[0029] The embodiment of the invention discloses an integrated attached lifting scaffolding flap device.

[0030] Example 1

[0031] The present invention provides Figure 1-4 An integrated attached lifting scaffolding flap device shown includes multiple pipe fittings 1 and a flap base 2, a surface of the flap base 2 is provided with a placement groove, a flap 3 is provided in the placement groove, a support rod 4 is fixed inside the placement groove, and a rotating hole matching the support rod 4 is provided inside the flap 3.

[0032] The flap base 2 can be connected to the pipe fitting 1, and the flap 3 can rotate around the support rod 4 to separate from and cooperate with the placement groove.

[0033] In order to quickly connect the flap base 2 and the pipe fitting 1, as shown in FIG. Figure 1 and Figure 4 As shown, strip grooves are provided on both sides of the surface of the flap base 2, and a plug-in mechanism for connecting with the pipe fitting 1 is provided in each strip groove. The plug-in mechanism includes two symmetrically arranged fixing plates 6, and the two fixing plates 6 are fixed in the strip grooves, and fixing rods 7 are fixedly penetrated inside. Sleeves 8 are slidably sleeved on both ends of the rod wall of the fixing rod 7, and the end of the sleeve 8 passes through the flap base 2 and is inserted into the pipe fitting 1. A plug-in hole for matching the sleeve 8 is provided inside the pipe fitting 1, and a first spring 9 is sleeved on the rod wall of the fixing rod 7, and the two ends of the first spring 9 are fixedly connected to the fixing plate 6 and the sleeve 8 respectively. The outer walls of the plurality of sleeves 8 are fixedly provided with pull rods 10, and the pull rods 10 pass through the strip grooves and extend to the outside.

[0034] After the position of the pipe fitting 1 of the scaffolding is determined, a hole is opened inside the pipe fitting 1 in advance, and the flap base 2 is placed between four adjacent pipe fittings 1. Prior to this, the pull rod 10 is pulled to allow the sleeve 9 to slide along the fixed rod 7 and squeeze the first spring 9. At this time, the sleeve 8 is located in the strip groove. When the position of the flap base 2 is determined, the pull rod 10 is released, and the elastic force of the first spring 9 is restored to allow the sleeve 8 to be inserted into the plug-in hole inside the pipe fitting 1, thereby completing the position determination of the flap base 2 and the flap 3 in turn.

[0035] Example 2

[0036] Embodiment 2 is based on Embodiment 1 in order to avoid the longitudinal jumping of the flap 3 as much as possible after the flap 3 is turned over. Figure 1-2 As shown, a rotation limiting mechanism for limiting the rotation position of the flap 3 is provided between the rotating hole and the support rod 4, the rotation limiting mechanism includes a limiting rod 11, a telescopic rod 13 with a second spring 12 is fixedly connected to the bottom of the inner wall of the rotating hole, the top of the telescopic rod 13 is in contact with the support rod 4, the limiting rod is fixedly connected to the top of the inner wall of the rotating hole and inserted into the support rod 4, a limiting hole is provided inside the support rod 4 for inserting the limiting rod 11, and pulling holes are provided at both feet of the top of the flap 3.

[0037] Before the flap 3 is used, the flap 3 is located in the placement groove and the limit rod 11 is inserted into the limit hole. However, when the flap 3 needs to be flipped, the flap 3 is pushed so that the internal rotating hole of the flap 3 squeezes the telescopic rod 13 and the second spring 12, so that the limit rod 11 is separated from the limit hole. Then the flap 3 is turned out and the flap 3 is released. The elastic force of the second spring 12 is used to reinsert the limit rod 11 into the limit hole to fix the position of the flap 3, thereby minimizing longitudinal jumping and position deviation of the flap 3 when it is stepped on.

[0038] Example 3

[0039] Embodiment 3 is based on Embodiment 1 to extend the flap 3 and determine the position of the extension plate 5. Figure 1 and Figure 3 As shown, the positioning mechanism includes a positioning rod 14, a plurality of positioning holes arranged at intervals are opened on the side wall of the extension cavity, a cavity is opened inside the extension plate 5, and the top is slidably sleeved with the positioning rod 14, the upper end of the positioning rod 14 is inserted into the positioning hole, and the lower end of the positioning rod 14 is sleeved with a third spring 15, and the two ends of the third spring 15 are respectively fixedly connected to the positioning rod 14 and the cavity, a screw rod 16 is rotatably penetrated through the side wall of the extension plate 5, one end of the screw rod 16 penetrates into the cavity and is fixedly provided with a push block 17, the push block 17 is cooperatively connected with the positioning rod 14, and the other end of the screw rod 16 is fixedly provided with a knob 18.

[0040] When the flap 3 needs to be extended after rotation, the positioning rod 14 is located in the cavity, and the extension plate 5 is pulled to slide in the extension cavity. When the position of the extension plate 5 is determined, the knob 18 is turned to drive the screw 16 to rotate, so that the push block 17 moves horizontally and pushes the positioning rod 14, so that the positioning rod 14 stretches the third spring 15 while passing through the extension plate 5 and plugging into the positioning hole on the flap 3, completing the position fixation of the extension plate 5. In order to ensure that the positioning rod 14 can be pushed stably, as shown in FIG. Figure 3 As shown, the push block 17 is a truncated cone block, and is provided with an inclined surface at the lower end of the side wall of the positioning rod 14 for contact and cooperation.

[0041] When the push block 17 moves, since the push rod 17 is a truncated cone block with an inclined side wall, it can stably contact and cooperate with the inclined surface of the lower end of the positioning rod 14, so that the positioning rod 14 can be pushed longitudinally during the lateral movement.
