Description

Technical Field

[0001] The invention relates to the technical field of scaffolds, and in particular to a disc-lock structure of a disc-lock type scaffold. Background Art

[0002] The scaffolding is a common scaffolding used in construction. Its structure is mainly composed of vertical poles, horizontal poles and scaffolding connectors. Through the scaffolding connectors, a stable structure is formed, which can withstand large loads. The scaffolding can also freely adjust the height and layout according to construction needs to adapt to various construction environments. In order to ensure safety and stability during installation, the bolts of the scaffolding usually need to be hammered with a hammer to enhance the fixity of the bolts.

[0003] In the prior art, the buckle connectors are mostly connected to the vertical poles by welding and are non-detachable. Vertical poles with different diameters need to be equipped with different buckle connectors, which is very troublesome. The vertical poles may have different connection heights with the cross bars or diagonal bars in different construction occasions. Since the position of the buckle connector is fixed, it is necessary to have vertical poles with buckle connectors of different heights or to add additional buckle connectors, which is inconvenient. In addition, the buckle connectors are connected to the fastener heads of the cross bars or diagonal bars by pins, and there is no further fixing device. When erecting scaffolding, workers can easily make the rod-shaped components touch and knock the erected scaffolding in the process of handing over parts. Repeated touching and knocking will vibrate the buckle pins of the scaffolding, and the pins will become loose due to the influence of external force. At the same time, when the scaffolding shakes during use, the pins will also loosen, thereby affecting its fixed state, thereby reducing the stability of the scaffolding and increasing the risk of collapse.

[0028] Furthermore, slideways 116 are provided on the upper and lower surfaces of the annular groove 112, and columns 214 are fixedly provided on the upper and lower surfaces of the locking block 21. A slider 215 is fixedly provided at the end of the column 214, and the slider 215 is slidably connected to the slideway 116. A plurality of avoidance grooves 213 are spaced apart on the surface of one side of the locking block 21, and a plurality of convex plates 212 are fixedly provided on the surface of the other side at intervals. The plurality of convex plates 212 correspond one-to-one to the plurality of avoidance grooves 213 of adjacent locking blocks 21, and the convex plates 212 are slidably connected to the corresponding avoidance grooves 213. This arrangement can also increase the anti-slip effect on the surface of the upright 4.

[0029] Furthermore, the convex plate 212 abuts against the outer wall of the vertical rod 4, and a plurality of protrusions 16 are fixedly arranged on the inner wall of the annular groove 112 along the circumferential direction. The protrusions 16 extend to the outside of the locking block 21, and a threaded hole 161 is penetrated through the surface of the protrusion 16 on one side facing the locking block 21.

[0030] Furthermore, a rotating member 22 is fixedly provided at one end of the driving plate 23 away from the disc 12, and a plurality of connecting columns 221 are circumferentially provided on the surface of one end of the rotating member 22 close to the driving plate 23. A plurality of avoidance holes 118 are circumferentially penetrated through the outer sides of the upper and lower surfaces of the locking plate 11, and the plurality of connecting columns 221 correspond to the plurality of avoidance holes 118 one by one.

The outer wall of the connecting column 221 is slidably connected with the inner wall of the annular groove 112. The driving plate 23 is driven to rotate by the rotating member 22, and then the locking block 21 is driven to move by the driving plate 23, thereby changing the size of the locking cavity. The moved locking block 21 is tightened by the locking screw 18, so that the locking block 21 can clamp the vertical rod 4 to prevent the locking plate 11 and the vertical rod 4 from sliding relative to each other.

[0031] The cam 334 is provided with a plurality of springs 335 on the bottom surface of the locking cam 336, and the cam 336 is provided with a plurality of springs 336 on the bottom surface of the locking cam 336. When the pawl 332 passes through a tooth of the locking groove 314, the reset spring 335 will shrink accordingly. If the pressure plate 33 moves in the opposite direction, the tooth of the locking groove 314 will lock the pawl 332. At this time, the unlocking block 331 is pulled to separate the pawl 332 from the locking groove 314, and the pressure plate 33 can be moved in the opposite direction. The provided latch member 31 and the pressure plate 33 cooperate with each other to lock the fastener head and prevent the latch member 31 from loosening. At the same time, it can also adapt to fastener heads of different lengths, increase the stability of the scaffolding, and reduce the risk of collapse.

[0032] Furthermore, a plurality of first connection holes 121 and a plurality of second connection holes 122 are arranged at intervals along the circumferential direction on the surface of the disk 12, and the plurality of first connection holes 121 and the plurality of second connection holes 122 are arranged alternately in sequence, and the fastener head at the end of the cross bar 5 is plugged into the first connection hole 121, the upper surface of the accommodating block abuts against the lower surface of the fastener head, and the lower surface of the pressure plate 33 abuts against the upper surface of the fastener head. The second connection hole 122 is used to connect the diagonal rod, and the fastener head of the diagonal rod is installed in the same manner as the cross bar 5. At the same time, in order to prevent the convex plate 212 of the locking block 21 from sliding relative to the surface of the vertical rod 4, a locking groove corresponding to the convex plate 212 can be opened on the surface of the vertical rod 4 to make the connection more stable.

[0033] When the disc-type scaffolding disc-type buckle structure is in use, the locking plate 11 needs to be installed in the middle of the vertical pole 4, the locking plate 11 is inserted into the vertical pole 4, and when the end of the vertical pole 4 contacts the inclined surface of the top tightening block 13, as the vertical pole 4 is inserted, the top tightening spring 114 contracts, and the top tightening block 13 slides into the groove 113, so that the space between the multiple top tightening blocks 13 becomes larger until the vertical pole 4 passes through. When the locking plate 11 is inserted into the required position, the rotating member 22 is rotated, and the rotating member 22 rotates, driving the driving plate 23 to rotate, and the driving plate 23 drives the locking block 21 to move until the convex plate 212 of the locking block 21 abuts against the outer wall of the vertical pole 4, and then the locking screw 18 is rotated, and the locking screw 18 moves until the end of the locking screw 18 abuts against the corresponding locking block 21. When the locking plate 11 is connected to the vertical rod 4, the locking plate 11 is installed on the other vertical rods 4 in the same way. When it is necessary to connect the cross bar 5 or the diagonal rod to the vertical rod 4, the fastener head of the cross bar 5 or the diagonal rod is plugged into the disc 12, and the fastener hole on the fastener head is aligned with the corresponding first connecting hole 121 or second connecting hole 122, so that the insertion rod 311 of the latch member 31 passes through the fastener hole and the connecting hole, and the lower surface of the baffle plate 312 abuts against the upper surface of the fastener head, and then the pressure plate 33 is inserted from the lower end of the insertion rod 311, and the pressure plate 33 slides upward until the upper surface of the pressure plate 33 abuts against the lower surface of the fastener head, and the pressure plate 33 is self-locked under the cooperation of the pawl 332 and the positioning groove 314, and the pressure plate 33 cooperates with the baffle plate 312 to lock the fastener head. At this time, the connection between the cross bar 5 or the diagonal rod and the vertical rod 4 is completed; When the locking disk 11 needs to connect the two vertical rods 4, the opposite ends of the two vertical rods 4 are inserted into the locking disk 11 at the same time, and the ends of the two vertical rods 4 abut against the middle of the accommodating hole 117, and then the rotating part 22 is rotated to make the locking blocks 21 at both ends of the locking disk 11 abut against the outer walls of the corresponding vertical rods 4 respectively, and the locking screw 18 is rotated to tighten the locking block 21. At this time, the two sections of the vertical rods 4 are connected. When it is necessary to remove the cross bar 5 or the diagonal bar, it is only necessary to push the unlocking block 331 outward. The unlocking block 331 drives the pawl 332 to separate from the positioning groove 314, and the insertion rod 311 is separated from the pressure plate 33, and then the pin member 31 is taken out. When removing the vertical rod 4, it is only necessary to rotate the tightening screw in the opposite direction. When the device is in use, the locking plate 11 can be freely combined on the vertical pole 4, and can be assembled into scaffolds of different shapes and sizes with the cross bar 5 and the diagonal bar, so that the height and layout of the scaffold can be adjusted more freely. At the same time, with the clamping component 2 and the locking component 3, the installation and disassembly of the scaffold is also faster and more convenient, thereby improving work efficiency.
