Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, and in particular to a quick-assembly and disassembly structure for disc-lock scaffolding and its method of use. Background Technology

[0002] Disc-type scaffolding is a new type of scaffolding introduced from Europe in the 1980s. It is an upgraded version of the cup-lock scaffolding. This type of scaffolding typically consists of uprights and horizontal bars. The uprights are made of steel pipes of a certain length, with a disc welded at regular intervals. These novel and aesthetically pleasing discs connect to the horizontal bars, and the bottom has a connecting sleeve. The horizontal bars are made of steel pipes with plugs fitted with pins welded to both ends, connecting to the discs.

[0003] CN112031375B discloses a disc-lock scaffolding, which discloses a disc that is movably connected to the uprights, but it still has the following disadvantages and deficiencies: The installation method between the disc and the upright is extremely complicated. Operators need to install multiple parts during installation, which is inconvenient. In addition, the method of connecting the horizontal bar and the disc with wedge pins is also quite complicated. Operators need to use external tools to hammer and tighten it, which affects the efficiency of scaffolding installation and dismantling. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a quick-assembly and disassembly structure for disc-lock scaffolding and its usage method.

[0005] To solve the above-mentioned technical problems, the present invention provides a quick assembly and disassembly structure for disc-lock scaffolding, comprising uprights and horizontal bars.

[0006] In the above scheme, preferably, the upright is provided with a movable disc; The upright is provided with a plurality of mounting hole groups, and the disc is provided with a plurality of locking pins that cooperate with the mounting hole groups. The disc is provided with a first elastic piece and a pin hole that are adapted to the locking pin. One end of the locking pin is engaged with the first elastic piece, and the other end slides through the pin hole. The first elastic sheet is an arc-shaped sheet, which can elastically deform to the other side and stabilize the deformation state after being subjected to force on one side.

[0007] In the above scheme, preferably, the first elastic sheet is made of manganese steel plate, and the locking pin is provided with a groove that cooperates with the first elastic sheet.

[0008] In the above scheme, preferably, the crossbar includes a connector, the disc has a hole that mates with the connector, and the connector has a latch that movably mates with the hole.

[0009] In the above scheme, preferably, the connector includes a top plate, a bottom plate and a movable groove, and the buckle is rotatably disposed on the top plate and its lower end is movably disposed in the movable groove.

[0010] In the above scheme, preferably, a drive arm is provided on the side of the upper end of the buckle away from the connector, and a top pin that cooperates with the drive arm is slidably provided on the side of the top plate away from the connector. The top pin slides against the upper surface of the disc and then engages with the drive arm to rotate the buckle and lock it into the disc hole.

[0011] In the above scheme, preferably, the buckle is provided with a first protrusion and a second protrusion on both sides to cooperate with the wall of the disc hole.

[0012] In the above scheme, preferably, the bottom plate is provided with a second elastic piece that cooperates with the locking pin at the end away from the connector, and the second elastic piece is provided with a locking groove that engages with the locking pin after elastic deformation.

[0013] In the above scheme, preferably, the second elastic sheet is an arc-shaped sheet that is equidistant from the first elastic sheet, and its material is manganese steel plate.

[0014] In the above scheme, preferably, the disc includes a sliding sleeve, and the first elastic piece is provided with support plates at both ends that are connected to the outer wall of the sliding sleeve. The first elastic piece, the support plates on both sides and the outer wall of the sliding sleeve form an opening groove for the operator to drive.

[0015] In the above scheme, a preferred method for using a disc-lock scaffolding quick-assembly and disassembly structure is as follows: S1: When in use, first put the disc on the upright, then slide the disc to the corresponding mounting hole group position, then press the first elastic piece to deform the first elastic piece towards the center of the disc, so that the locking pin slides into the mounting hole of the mounting hole group to achieve circumferential and axial locking between the disc and the upright. S2: Then slide the connector of the crossbar into the disk through the movable groove. When sliding, the upper end face of the second elastic plate will contact the lower end face of the disk. At this time, the lower end face of the top pin is placed above the disk. S3: In step S2, the buckle rotates after contacting the edge of the disc. Then, as the connector continues to slide, the buckle disengages from the upper surface of the disc, rotates back to its original position, and slides into the disc hole. S4: Then, press the connector to make the buckle slide downward relative to the disc hole, while the top pin slides upward relative to the connector. During the sliding process, the drive arm of the buckle is pressed against the upper end face of the top pin, causing the buckle to rotate in the disc hole, and finally the first protrusion and the second protrusion contact and press against the hole wall of the disc hole. S5: During the S4 operation, the second elastic plate slides down synchronously and eventually slides to the position corresponding to the first elastic plate. Finally, the second elastic plate is pressed to make it elastically deform towards the first elastic plate. At this time, the opening groove on the second elastic plate slides and engages with the locking pin, so that the connector is locked by the locking pin when it slides upward and cannot move, thus realizing the fixed connection between the connector and the disc.

[0016] The beneficial effects of this invention are as follows: This invention provides a quick assembly and disassembly structure for disc-lock scaffolding and its usage method. By setting a first elastic plate and a locking pin in a pressing fit, the disc can be quickly fixedly connected to the upright, achieving rapid installation of the disc. Furthermore, a movable buckle is set in the connector, and the horizontal bar and disc are quickly installed by the pressing fit between the buckle and the disc hole, achieving the effect of quick assembly and disassembly, improving the installation speed of scaffolding and reducing installation costs.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-6 A quick-assembly and disassembly structure for disc-lock scaffolding includes uprights 1 and horizontal bars 2. The uprights 1 are provided with movable discs 3, which are disc-lock discs, and this is the prior art.

[0024] Based on the aforementioned disc-type disc, this embodiment further improves the disc 3. Specifically, the disc 3 includes a sliding sleeve 306 integrally formed therewith, such as... Figure 3-4As shown, the upright 1 is a hollow circular tube with several sets of mounting holes 101 evenly spaced on it. The mounting hole set 101 is a circular hole that penetrates the tube wall and is evenly arranged around the circumference. In this embodiment, four mounting holes are used as an example. A locking pin 301 is provided on the sliding sleeve 306 to match the number of mounting holes. The locking pin 301 is slidably disposed on the wall of the sliding sleeve 306. The sliding sleeve 306 is provided with a pin hole 303 that matches the locking pin 301.

[0025] The outer wall of the sliding sleeve 306 is uniformly fixed with first elastic pieces 302, matching the number of locking pins 301. Each first elastic piece 302 is arc-shaped, with a locking hole for mounting the locking pin 301 at the center of its arc. One end of each locking pin 301 has a groove 304 that matches the locking hole. That is, one end of the locking pin 301 is engaged with the first elastic piece 302 through the groove 304, and the other end passes through the pin hole 303 of the sliding sleeve 306. Initially, the first elastic pieces 302 are in the following state: Figure 4 As shown, after the locking pin 301 is installed, one end of it is hidden inside the sliding sleeve 306.

[0026] The first elastic piece 302 is preferably made of manganese steel plate. Its two ends are fixedly connected to the outer wall of the sliding sleeve 306 through the support plate 307. When the first elastic piece 302 is pressed towards the axis of the sliding sleeve 306, the first elastic piece 302 can be deformed, so that the outermost arc is deformed and placed near the outer wall of the sliding sleeve 306. When installing the disc 3, the sliding sleeve 306 is fitted onto the outer wall of the upright 1, and then it is moved to any mounting hole group 101. At this time, any first elastic piece 302 is pressed and the sliding sleeve 306 is rotated in coordination, so that the locking pin 301 driven by the first elastic piece 302 slides into the mounting hole of the mounting hole group 101 through the pin hole 303, realizing the axial and circumferential positioning of the disc 3. Then the remaining first elastic pieces 302 are pressed to complete the positioning and installation of the disc 3.

[0027] In this embodiment, to facilitate the installation and disassembly of the disc 3, the first elastic piece 302 forms an opening groove 308 when it is fixedly connected to the sliding sleeve 306 via the support plate 307. When the first elastic piece 302 is pressed and deformed and approaches the outer wall of the disc 3, that is, after the locking pin 301 is inserted into the mounting hole group 101, the inner wall of the first elastic piece 302 can be pried by inserting a rod-shaped object into the opening groove 308, causing it to deform away from the center of the disc 3, thereby disengaging the locking pin 301 from the mounting hole group 101 and completing the disassembly of the disc 3. It can be seen that the first elastic piece 302 can achieve elastic deformation to the other side and stabilize the deformation state after being subjected to force on one side.

[0028] To facilitate quick assembly and disassembly of the crossbar 2 and the disc 3, the crossbar 2 includes a connector 201. The connector 201 comprises a top plate 203, a bottom plate 204, and a movable groove 205. The movable groove 205 is located in the central area formed by the top plate 203 and the bottom plate 204. The connector 201 is movably equipped with a buckle 202 that mates with the disc hole 305. Figure 2 , 3 As shown in Figures 5 and 6, the upper end of the buckle 202 is rotatably mounted on the top plate 203 via a rotating pin. The top plate 203 has a hollow groove for the buckle 202 to rotate without interference, and its lower end is movably mounted in the movable groove 205. The disc 3 has a disc hole 305 that mates with the connector 201. During installation, the edge of the disc 3 enters the movable groove 205, at which point the disc 3 contacts the buckle 202, causing the buckle 202 to move along... Figure 2 As shown, rotate counterclockwise by a certain angle. When the disc hole 305 is positioned below the buckle 202 after the disc 3 is displaced, the buckle 202 disengages from the disc 3 and resets clockwise to above the disc hole 305. Then, press the connector 201 downwards so that the lower end of the buckle 202 slides into the disc hole 305, allowing the buckle 202 to engage with the disc hole 305.

[0029] To ensure a tight engagement between the latch 202 and the disc hole 305 after the connector 201 is pressed, a drive arm 206 extending towards the side of the latch 202 away from the connector 201 is provided. A top pin 207, which slidably engages with the drive arm 206, is vertically slidably provided on the top plate 203 away from the connector 201; that is, the upper end of the top pin 207 is positioned below the drive arm 206. The top pin 207 slides against the upper surface of the disc 3 and then engages with the drive arm 206. The buckle 202 rotates and engages with the disc hole 305. The buckle 202 has a first protrusion 208 and a second protrusion 209 on both sides that cooperate with the hole wall of the disc hole 305. When the buckle 202 is engaged with the disc hole 305, the first protrusion 208 and the second protrusion 209 press against the hole walls on both sides of the disc hole 305, realizing the engagement between the buckle 202 and the disc 3. At this time, the connector 201 achieves horizontal fixation and vertical downward displacement limitation.

[0030] To further secure the buckle 202 after it is engaged, i.e., to limit its upward displacement, this embodiment provides a second elastic piece 210 on the bottom plate 204 away from the connector 201, which cooperates with the locking pin 301. The second elastic piece 210 has a locking groove 211 that engages with the locking pin 301 after elastic deformation. Preferably, the locking groove 211 is an open groove at one end. Figure 5 The end shown is near the top plate 203; the second elastic piece 210 is an arc-shaped piece equidistant from the first elastic piece 302, and its material is manganese steel plate. When the buckle 202 is engaged with the disc 3, Figure 1 , 3In state 5, the second elastic piece 210 is pressed against the upright 1, so that the locking groove 211 and the locking pin 301 are engaged at one end outside the first elastic piece 302. At this time, when the connector 201 moves upward, it is limited by the locking pin 301 and the lower end of the locking groove 211, thus realizing the vertical and horizontal locking between the connector 201 and the disc 3.

[0031] A method for using a quick-assembly and disassembly structure for disc-lock scaffolding is as follows: S1: When in use, first put the disc 3 on the upright 1, then slide the disc 3 to the corresponding mounting hole group 101 position, then press the first elastic piece 302 to deform the first elastic piece 302 towards the center of the disc 3, so that the locking pin 301 slides into the mounting hole of the mounting hole group 101 to achieve circumferential and axial locking between the disc 3 and the upright 1; S2: Then slide the connector 201 of the crossbar 2 into the disk 3 through the movable groove 205. When sliding, the upper end face of the second elastic piece 210 contacts the lower end face of the disk 3. At this time, the lower end face of the top pin 207 is placed above the disk 3. S3: In step S2, after the buckle 202 contacts the edge of the disk 3, it rotates. Then, as the connector 201 continues to slide, the buckle 202 disengages from the upper surface of the disk 3, rotates back to its original position, and slides into the disk hole 305. S4: Then, press the connector 201 to make the buckle 202 slide downward relative to the disc hole 305, while the top pin 207 slides upward relative to the connector 201. During the sliding process, the drive arm 206 of the buckle 202 is pushed against the upper end face of the top pin 207, causing the buckle 202 to rotate in the disc hole 305, and finally the first protrusion 208 and the second protrusion 209 contact and push against the hole wall of the disc hole 305. S5: During the action of S4, the second elastic plate 210 slides down synchronously and finally slides to the position corresponding to the first elastic plate 302. Finally, the second elastic plate 210 is pressed to make it elastically deform towards the first elastic plate 302. At this time, the opening groove 308 on the second elastic plate 210 slides and engages with the locking pin 301, so that the connector 201 is locked by the locking pin 301 when it slides upward and cannot move, thus realizing the fixed connection between the connector 201 and the disc 3. S6: During disassembly, the operator uses a rod-shaped object to pry the second elastic plate 210 to elastically deform it away from the upright 1, causing the locking groove 211 on the second elastic plate 210 to disengage from the locking pin 301. At this time, the limit on the upward displacement of the connector 201 is released. By lifting the connector 201 upward, the buckle 202 slides out of the disc hole 305. Then, the connector 201 is moved away from the upright 1 to disengage it from the disc 3, thus completing the disassembly.
