Description

Technical Field

[0001] This application relates to the field of disc buckle support frame technology, and in particular to a locking structure for a quick-installation assembly disc buckle support frame. Background Technology

[0002] Due to its many advantages, such as high load-bearing capacity, high safety, good stability, fast assembly and disassembly speed, open working space, neat and beautiful appearance, and saving labor costs, the disc-lock scaffold has been successively applied to housing construction projects, other important construction projects, road and bridge projects, municipal engineering, stage construction, large-scale cultural and sports facilities and other fields.

[0003] During the erection of disc-lock scaffolding, the adjustable bases are typically placed first, followed by the insertion of scaffolding uprights onto the bases. Then, the connectors on the horizontal bars are placed onto the support plates on the uprights between two adjacent uprights. Finally, pins are inserted between the support plates on the uprights and the connectors on the horizontal bars. After inserting the pins, workers need to hammer them to tighten them. This method of fixing the horizontal bars to the uprights and inserting pins, followed by hammering each pin individually, is cumbersome. Furthermore, the disc-lock scaffolding's connection to the uprights is fixed, meaning the position of the disc-locks is fixed and cannot be adjusted vertically, thus failing to meet different usage needs.

[0004] To address this, a locking structure for a quick-assembly modular disc buckle support frame is proposed. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a locking structure for a quick-installation assembly disc buckle support frame.

[0006] This application provides a locking structure for a quick-installation, modular disc-type support frame, employing the following technical solution: It includes a lower support member and an upper support member. A fixed cylinder is positioned above the lower support member, and a plug-in cylinder is fixedly connected to the top of the fixed cylinder. A connecting plate is sleeved on the outside of the fixed cylinder, and multiple connecting holes are formed on the surface of the connecting plate. An installation adjustment component is provided between the connecting plate and the fixed cylinder. A crossbar is positioned on the outside of the fixed cylinder, and mounting seats are fixedly connected to both ends of the crossbar. Two mounting holes are formed through the surface of the mounting seats, and the two mounting holes are correspondingly installed to the sides of the connecting holes on the connecting plate via the mounting seats. A plug is installed between the connecting holes and the two mounting holes, and a fixing component is provided on one side of the plug.

[0007] Optionally, the fixing assembly includes a transverse groove, a connecting rod, a rigid spring, a retaining block, and a drive handle. The transverse groove is formed on the outside of the insert block. The retaining block is slidably connected to the inside of the transverse groove. One end of the connecting rod is fixedly connected to one side of the retaining block, and the other end of the connecting rod extends through to the outside of the insert block and is fixedly connected to one end of the drive handle. The rigid spring is sleeved and installed on the outside of the connecting rod, and both ends of the rigid spring are fixedly connected to one side of the retaining block and the inside of the transverse groove, respectively. One side of the retaining block is set with an inclined surface.

[0008] Optionally, the lower support includes a base plate, a first stud, and a rotating sleeve. The first stud is fixedly connected to the top of the base plate, and the rotating sleeve is threadedly connected to the outside of the first stud.

[0009] Optionally, the upper support includes a second stud, a rotating handle, and a support base. The second stud is fixedly connected to the bottom of the support base, and the rotating handle is threadedly connected to the outside of the second stud.

[0010] Optionally, the installation adjustment assembly includes an external thread, a first nut, and a second nut. The connecting disc is sleeved and installed on the outside of the external thread. The first nut and the second nut are threaded onto the outside of the external thread, and the internal threads of the first nut and the second nut are opposite in direction. The first nut and the second nut abut against each other with the connecting disc.

[0011] Optionally, the fixing sleeve is installed outside the first stud, and the bottom end of the second stud is installed inside the insertion sleeve.

[0012] Optionally, two limiting plates are fixedly connected to both sides of the insert block, and the two limiting plates are installed above the mounting base.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, through the setting of a fixing component, a plug, a mounting base, and mounting holes, etc., is installed on the outside of the connecting plate by the mounting base, and the mounting holes are aligned vertically with the connecting holes, so that the plug is installed inside the mounting holes and connecting holes. Under the action of the spring, the connecting rod is driven to move and push the clamping block. After the clamping block moves, the mounting block and the connecting plate are locked together. At the same time, when removing, only the drive handle is used to pull the pull rod to move the clamping block, which can complete the removal of the plug from the mounting holes and connecting holes. This facilitates installation and disassembly, reduces the trouble of traditional methods of inserting a pin and hammering, and improves the work efficiency of scaffolding assembly.

[0015] 2. This utility model, by setting up an adjustment component and a connecting plate, allows the connecting plate to move on the external thread and be tightened by the rotation of the threads of the first nut and the second nut, facilitating the vertical height adjustment of the connecting plate and meeting different needs.

[0022] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0023] This application discloses a locking structure for a quick-assembly modular disc buckle support frame. For example... Figures 1 to 3 As shown, a fixed cylinder 2 is provided above the lower support 5. A plug-in cylinder 12 is fixedly connected to the top of the fixed cylinder 2. A connecting plate 3 is sleeved on the outside of the fixed cylinder 2. Multiple connecting holes 4 are opened on the surface of the connecting plate 3. An installation adjustment component is provided between the connecting plate 3 and the fixed cylinder 2. The installation adjustment component includes an external thread 6, a first nut 13 and a second nut 7. The connecting plate 3 is sleeved on the outside of the external thread 6. The first nut 13 and the second nut 7 are threaded on the outside of the external thread 6, and the internal threads of the first nut 13 and the second nut 7 are opposite in direction. The first nut 13 and the second nut 7 abut against the connecting plate 3. By rotating the first nut 13 and the second nut 7 on the external thread of the external thread 6 and locking the connecting plate 3, the height of the connecting plate 3 can be adjusted.

[0024] Please see Figure 1 and Figure 2The fixing cylinder 2 is sleeved and installed outside the first stud 1, and the bottom end of the second stud 112 is installed inside the plug-in cylinder 12. Two limiting plates 19 are fixedly connected to both sides of the plug 22. The two limiting plates 19 are installed above the mounting base 9. The limiting plates 19 facilitate the position limitation of the plug 22 after installation.

[0025] Please see Figure 1 and Figure 5 The system includes a lower support member 5 and an upper support member 11. The upper support member 11 includes a second stud 112, a rotating handle 113, and a support base 111. The second stud 112 is fixedly connected to the bottom of the support base 111. The rotating handle 113 is threadedly connected to the outside of the second stud 112. By rotating the rotating handle 113 on the outside of the second stud 112, the height of the upper support member 11 can be easily adjusted. The lower support member 5 includes a base plate 21, a first stud 1, and a rotating sleeve 20. The first stud 1 is fixedly connected to the top of the base plate 21. The rotating sleeve 20 is threadedly connected to the outside of the first stud 1. By rotating the rotating sleeve 20 on the outside of the first stud 1, the height of the lower support member 5 can be easily adjusted.

[0026] Please see Figure 3 and Figure 4 A crossbar 8 is provided on the outer side of the fixed cylinder 2. Mounting seats 9 are fixedly connected to both ends of the crossbar 8. Two mounting holes 10 are formed through the surface of the mounting seats 9. The two mounting holes 10 are connected to the corresponding connecting holes 4 on both sides of the connecting plate 3 via the mounting seats 9. Insert blocks 22 are installed between the connecting holes 4 and the two mounting holes 10. Insert blocks 22 are installed into the connecting holes 4 and the mounting holes 10 to connect the mounting seats 9 and the connecting plate 3. A fixing component is provided on one side of the insert block 22. The fixing component includes a horizontal groove 17, a connecting rod 15, a rigid spring 16, a retaining block 18, and a drive handle 14. The horizontal groove 17 is formed on the outer side of the insert block 22, and the retaining block 18 is slidably connected to the horizontal groove 17. Inside, one end of the connecting rod 15 is fixedly connected to one side of the abutment block 18, and the other end of the connecting rod 15 extends through to the outside of the insert block 22 and is fixedly connected to one end of the drive handle 14. By setting the drive handle 14, the connecting rod 15 can be pulled to move under the action of the drive handle 14, and the abutment block 18 can be moved by the movement of the connecting rod 15. The rigid spring 16 is sleeved and installed on the outside of the connecting rod 15, and the two ends of the rigid spring 16 are fixedly connected to one side of the abutment block 18 and the inside of the transverse groove 17, respectively. One side of the abutment block 18 is set with an inclined surface. The abutment block 18 is driven to move by the action of the rigid spring 16, so that the abutment block 18 is located below the mounting base 9 and is firmly clamped to the mounting base 9 and the connecting plate 3.

[0027] The implementation principle of the locking structure of the quick-installation assembly disc buckle support frame in this application embodiment is as follows: When in use, the base plate 21 is placed on the ground, and the rotating sleeve 20 is rotated outside the first stud 1 to adjust to a suitable height, so that the fixing cylinder 2 is installed outside the first stud 1. At the same time, the rotating handle 113 is rotated outside the second stud 112 to a suitable height, so that the second stud 112 is installed inside the plug-in cylinder 12.

[0028] Then, the crossbar 8 and the mounting base 9 on one side are installed to the outside of the connecting plate 3, so that the mounting hole 10 corresponds to the connecting hole 4. The insert 22 is then installed into the connecting hole 4 and the mounting hole 10. During the installation process, the clamping block 18 is pressed. The clamping block 18 moves, driving the connecting rod 15 to move and press the rigid spring 16, so that the clamping block 18 is completely inside the transverse groove 17. After the limiting plate 19 contacts the mounting base 9, the insert 22 is installed in the designated position. At this time, the clamping block 18 loses its force, and under the action of the rigid spring 16, the clamping block 18 is able to move and press the rigid spring 16 to press the rigid spring 16 to press the rigid spring 16 to press the rigid spring 18 ... The clamping block 18 moves inside the transverse groove 17, which can be clamped and installed at the bottom of the mounting base 9, so that the mounting base 9 is connected to the connecting plate 3 and clamped and fixed. When it is necessary to pull out the insert 22, simply pull the connecting rod 15 by the drive handle 14. The movement of the connecting rod 15 drives the clamping block 18 to move, which can complete the disengagement of the insert 22 from the mounting hole 10 and the connecting hole 4. This facilitates installation and disassembly, reduces the trouble of using a hammer to hit the pin when inserting it, and improves the work efficiency of scaffold assembly.

[0029] Next, when changing the height of the connecting plate 3, the first nut 13 and the second nut 7 can be rotated respectively to adjust the connecting plate 3 to a suitable height, and then the first nut 13 and the second nut 7 can be used to lock and fix it, which can meet the needs of different applications.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
