Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a detachable and portable scaffolding. Background Technology

[0002] Scaffolding is a commonly used auxiliary equipment in construction and decoration work, providing a platform for workers to stand and operate. Traditional scaffolding is mostly a fixed structure, cumbersome to install and dismantle, and bulky, making it inconvenient to transport and carry. Its use is particularly limited in scenarios requiring frequent changes of work location or where working space is limited. Therefore, there is an urgent need for a type of scaffolding that is easy to dismantle, carry, and assemble to meet practical needs. Summary of the Invention

[0003] The purpose of this utility model is to provide a detachable and portable scaffolding that, through optimized connection structure, enables rapid erection and dismantling, while being easy to carry and transport, thereby improving construction efficiency and safety.

[0004] The technical solution of this utility model is as follows: A detachable and portable scaffolding system includes multiple uprights, multiple horizontal bars, and footboards. The uprights and horizontal bars are detachably connected via a quick-connect mechanism. The quick-connect mechanism includes a connector at the top of the upright and a connector seat at the end of the horizontal bar that is adapted to the connector. Each footboard includes a footboard body and mounting portions on both sides of the footboard body; the mounting portions are adapted to the middle side of the horizontal bar, enabling stable installation and securing with locking devices.

[0005] The connector includes an eccentric quick-lock pin and a positioning connecting post. The positioning connecting post is a cuboid structure, protruding from one corner of the top of the column. Multiple eccentric quick-lock pins are provided, fixed to the two sides of the positioning connecting post near the central axis of the column. Each eccentric quick-lock pin includes a quick-lock base, a toggle pin body, and an eccentric shaft. One end of the quick-lock base is fixedly connected to the positioning connecting post, and the other end is eccentrically rotatably connected to the toggle pin body via the eccentric shaft. The toggle pin body is a column; its bottom surface near the quick-lock base is the first working surface, and its side parallel to the eccentric shaft is the second working surface; the distance between the first working surface and the eccentric shaft is less than the distance between the second working surface and the eccentric shaft. When extended, the eccentric quick-lock pin has an overall columnar structure. The connector is provided with a quick-lock pin adapter hole that precisely matches the eccentric quick-lock pin, allowing the eccentric quick-lock pin to be inserted and quickly locked by rotating and bending the eccentric quick-lock pin to press against the periphery of the quick-lock pin adapter hole. The connecting seat is also equipped with a lateral positioning post, which is a cuboid structure that is laterally set at the end of the crossbar. After installation, its side abuts against the side of the top of the column.

[0006] The quick-lock base includes a fixed base and a rotating shaft; the fixed base is fixed to the positioning connecting post; one end of the rotating shaft is rotatably connected to the fixed base about its own axis, and the other end is rotatably connected to the actuating pin about an eccentric axis. The spatial angle between the rotating shaft and the eccentric axis is within 90 degrees. This design makes the actuating pin more flexible during operation, allowing it to be moved to a position that facilitates quick locking and unlocking.

[0007] An arc-shaped curved surface tangent to both the first and second working surfaces is provided between the first and second working surfaces. This design allows the actuating pin to better fit against the hole wall when engaging with the quick-lock pin adapter hole, providing a more stable locking force.

[0008] The eccentric quick-lock pin also includes a guide plate fixed on the quick-lock base and a guide groove disposed within the actuating pin body. The guide plate is rotatably connected within the matching guide groove via an eccentric shaft perpendicular to it. The cooperation between the guide plate and the guide groove ensures the stability and accuracy of the rotation of the actuating pin body, making the operation of the eccentric quick-lock pin more reliable.

[0009] The mounting section consists of multiple crossbar latches located on both sides of the pedal. Each crossbar latch has a pair of latching plates on its sides that mate with the middle side of the crossbar. The locking element is an adjusting positioning pin. The end of each latching plate has a positioning pin adapter hole. The two positioning pin adapter holes on a pair of latching plates are aligned and connected, and are adapted to the adjusting positioning pin. The adjusting positioning pin can pass through the pair of positioning pin adapter holes to adjust the clamping tightness of the latching plates.

[0010] The adjusting positioning pin includes a connecting piece in the middle and adjusting pin bodies symmetrically arranged on both sides. The connecting piece and the adjusting pin bodies are rotatably connected by a positioning pin shaft. When straight, the connecting piece and the adjusting pin bodies are cylindrical; when bent, they are tri-fold cylindrical. A wave cam is provided on the adjusting pin body near the connecting piece. The wave cam is a wave-shaped curved surface with a step-increasing distance from the positioning pin shaft on the same side, which can abut against the wall of the positioning pin adapter hole to form a locking structure. This wave cam design allows the adjusting positioning pin to provide multi-level locking force when adjusting the clamping degree of the bayonet clip, adapting to different usage requirements.

[0011] The end of the wave cam is equipped with a protruding locking post, which abuts against the wall of the locating pin's adapter hole to form a limiting structure. The locking post further enhances the locking stability of the adjusting locating pin and prevents it from accidentally loosening during use.

[0012] The adjusting positioning pin also includes a positioning pin guide groove disposed within the adjusting pin body. Both ends of the connecting piece are respectively adapted to the positioning pin guide groove and are rotatably connected to the adjusting pin body within the positioning pin guide groove. The positioning pin guide groove ensures smooth and stable rotation between the connecting piece and the adjusting pin body.

[0013] The base of each column is also equipped with a column base. The column base has multiple column fixing holes. These fixing holes are through holes running vertically. Bolts and other connectors can be used to securely fix the columns to the ground or other supporting surfaces through these fixing holes, improving the overall stability of the scaffolding.

[0014] The beneficial effects of this utility model are as follows: Quick installation and dismantling: The quick-locking structure of the eccentric quick-locking pin and the connecting seat, as well as the quick adjustment of the platform installation part by the adjusting positioning pin, make the scaffolding erection and dismantling process free from the use of complicated tools, greatly saving time and labor costs and improving construction efficiency.

[0015] Portable: The scaffolding components are detachable, and the disassembled parts are small in size, making them easy to transport and store, and convenient to transfer between different construction sites.

[0016] Stable structure: The design of eccentric quick-locking pins, lateral positioning columns, and adjusting positioning pins ensures the firmness and stability of the connection between the uprights and horizontal bars, and between the scaffolding and the horizontal bars, ensuring that the scaffolding can withstand a certain weight and external force during use, and protecting the safety of construction workers.

[0017] Optimized locking effect: The rotating shaft can drive the actuating pin to rotate 90 degrees before locking. Since the actuating pin is a cuboid and its bottom surface is not square, after rotation, its long side and short side switch orientations, which can increase the pressure action surface of the first working surface, the arc surface and the second working surface around the fast locking pin adapter hole, improve the locking effect, and further improve the locking reliability of the connection between the column and the crossbar.

[0026] Example 1 I. Overall Structure like Figure 1-8 As shown, a detachable and portable scaffolding includes four uprights 1, four horizontal bars 2 arranged in pairs, two footboards 3, and a quick-connect mechanism. The main body of the uprights 1 and horizontal bars 2 is rectangular in shape and welded from square steel pipes. The bottom of the uprights 1 is provided with an upright base 13, on which four upright fixing holes 14 are distributed. These upright fixing holes 14 are through holes in the vertical direction, used to firmly fix the uprights 1 to the ground or other supporting surfaces.

[0027] The upright 1 and the crossbar 2 are detachably connected via a quick-connect mechanism. The quick-connect mechanism includes a connector and a connector seat. The connector is located at the top of the upright 1 and includes an eccentric quick-lock pin 11 and a positioning connecting post 12. The positioning connecting post 12 has a cuboid structure and protrudes from one corner of the top of the upright 1. The positioning connecting post 12 is a square steel tube welded to two vertically aligned sides integrally formed with the upright 1. Two eccentric quick-lock pins 11 are provided for each upright 1, made of high-quality carbon structural steel, and are fixed to the two sides of the positioning connecting post 12 near the central axis of the upright 1, perpendicular to each other. The eccentric quick-lock pin 11 includes a fixed seat 111, a moving pin body 112, a guide plate 113, a rotating shaft 115, and an eccentric shaft 116. The fixed base 111 is fixed on the positioning connecting post 12; one end of the rotating shaft 115 is perpendicular to the fixed base 111 and rotatably connected to it about itself as an axis, and the other end is fixedly connected to the guide plate 113; the guide plate 113 is eccentrically rotatably connected to the actuating pin 112 through the eccentric shaft 116; the spatial angle between the rotating shaft 115 and the eccentric shaft 116 is 90 degrees. The actuating pin 112 is also provided with a guide groove 114 that matches the guide plate 113. The guide plate 113 is set in the guide groove 114, and the eccentric shaft 116 passes perpendicularly through the guide plate 113 and the guide groove 114, is fixed to the actuating pin 112 on the outside, and is rotatably connected to the guide plate 113 on the inside. The actuating pin 112 is generally rectangular. The bottom surface near the quick-lock base is the first working surface 118, and the side parallel to the eccentric shaft 116 and far away from the eccentric shaft 116 is the second working surface 119. An arc-shaped curved surface 117 tangent to the first working surface 118 and the second working surface 119 is provided.

[0028] The connecting seat at the end of the crossbar 2 is adapted to the connector. The connecting seat is provided with a rectangular quick-locking pin adapter hole 22 that precisely matches the eccentric quick-locking pin 11. The eccentric quick-locking pin 11 can be inserted and the first working surface of the actuating pin body 112 can be changed to the second working surface by bending the eccentric quick-locking pin 11, thereby pressing the periphery of the quick-locking pin adapter hole 22 to achieve quick locking. The connecting seat is also provided with a lateral positioning post 21. The lateral positioning post 21 is a cuboid structure that is laterally set at the end of the crossbar 2. After installation, its side abuts against the side of the top of the column 1 to achieve positioning and prevent deformation of the connection angle between the crossbar 2 and the column 1.

[0029] The pedal 3 includes a pedal body and mounting portions on both sides of the pedal body. The mounting portions consist of four crossbar latches 36 on both sides of the pedal 3. The crossbar latches 36 are locked by adjusting positioning pins 31. Pairs of latch clips 32 are provided on both sides of the crossbar latches 36 to fit the middle side of the crossbar 2; the ends of the latch clips 32 are provided with positioning pin fitting holes 33, and the two positioning pin fitting holes 33 on a pair of latch clips 32 are aligned and connected, fitting with the adjusting positioning pins 31. The adjusting positioning pins 31 include a connecting piece 311 in the middle and adjusting pin bodies 312 symmetrically arranged on both sides. The connecting piece 311 and the adjusting pin bodies 312 are rotatably connected by a positioning pin shaft. When straight, it is a rectangular prism shape; when bent, it is a three-fold prism shape. A wave cam 313 is provided near the connecting piece 311 on the adjusting pin body 312. The wave cam 313 is a wave-shaped curved surface with a step-increasing distance from the positioning pin shaft on the same side. It can abut against the wall of the positioning pin adapter hole 33 to form a locking structure. The protruding locking position 314 at its end can abut against the wall of the positioning pin adapter hole 33 to form a limiting structure. The adjusting positioning pin 31 also includes a positioning pin guide groove 315 provided in the adjusting pin body 312. Both ends of the connecting piece 311 are respectively adapted to the positioning pin guide groove 315 and are rotatably connected to the adjusting pin body 312 in the positioning pin guide groove 315.

[0030] II. Scaffolding Erection Steps Preparation: At the construction site, ensure the ground is flat and firm, suitable for scaffold installation. Move all components, including uprights 1, horizontal bars 2, footboards 3, adjusting positioning pins 31, etc., to the installation location, and check that each component is intact and undamaged, without any deformation, damage, or other issues that may affect its use.

[0031] Column placement or installation: Place the column base 13 vertically to the ground in the predetermined position.

[0032] If conditions permit, bolts can be used to pass through the column fixing holes 14 to vertically fix the column 1 to the ground.

[0033] Four columns are placed or installed in this way, arranged in a rectangular pattern.

[0034] Connection between crossbar and column: Pick up a horizontal bar 2 and align the lateral positioning post 21 of the connecting seat at the end of the horizontal bar 2 with the inner side of the top of the column 1, so that the side of the lateral positioning post 21 is tightly against the inner side of the column 1 and the lower side of the end of the lateral positioning post 21 is tightly against the top of the column 1, which plays a preliminary positioning role.

[0035] At this point, the quick-locking pin adapter hole 22 on the connector is aligned with the eccentric quick-locking pin 11 on one side of the positioning connector 12. Insert the eccentric quick-locking pin 11 into the quick-locking pin adapter hole 22.

[0036] Operate the rotating shaft 115 to drive the actuating pin 112 to rotate 90 degrees (because the actuating pin 112 is a cuboid and its bottom surface is not square, its long side and short side switch orientations at this time). Since the spatial angle between the rotating shaft 115 and the eccentric shaft 116 is 90 degrees, this operation is relatively convenient, as it only involves the translation of the first working surface on the circumferential side of the quick-locking pin adapter hole 22.

[0037] Next, by actuating the actuating pin 112, the eccentric rotation of the eccentric shaft 116 causes the first working surface, the arc-shaped curved surface, and the second working surface of the actuating pin 112 to sequentially contact the circumferential side of the quick-locking pin adapter hole 22. Since the working surface increases after the rotating shaft 115 rotates 90 degrees, a more stable clamping force can be provided, achieving a quick locking connection between the upright 1 and the crossbar 2. Following the same method, the other crossbars are connected to the uprights to form the scaffold frame structure.

[0038] Pedal installation: Align the crossbar latches 36 on both sides of the pedal 3 with the middle side of the crossbar 2, so that the latch clips 32 fit against the crossbar 2. For example, there are two crossbar latches 36 on each side of the pedal 3, which are inserted into the appropriate positions in the middle of the crossbar 2.

[0039] The adjusting positioning pin 31 is passed through the aligned and through positioning pin adapter holes 33 on a pair of bayonet clips 32. The two ends of the connecting piece 311 of the adjusting positioning pin 31 are adapted to the positioning pin guide groove 315 in the adjusting pin body 312 to ensure smooth insertion.

[0040] The adjusting positioning pin 31 is bent so that the connecting piece 311 and the adjusting pin body 312 form a three-fold cylindrical shape. At this time, the wave cam 313 of the adjusting pin body 312 near the connecting piece 311 abuts against the wall of the positioning pin adapter hole 33. As the adjusting pin body 312 rotates, the wave-shaped curved surface of the wave cam 313 provides different degrees of locking force, and the construction personnel can adjust the clamping degree of the bayonet clip 32 on the crossbar 2 according to actual needs.

[0041] Once adjusted to the appropriate position, the locking position 314 at the end of the wave cam 313 abuts against the wall of the positioning pin adapter hole 33 to form a limiting structure, preventing the adjusting positioning pin 31 from loosening, thereby stably installing the pedal 3 on the crossbar 2. Repeat this step to install all pedals.

[0042] III. Scaffolding Dismantling Steps Remove the pedal: The locating pin 31 is adjusted in the reverse direction to straighten it into a cylindrical shape. Specifically, the adjusting pin 312 is rotated to disengage the wave cam 313 from the wall of the locating pin adapter hole 33.

[0043] At this point, the adjusting positioning pin 31 can be pulled out from the positioning pin adapter hole 33, and then the pedal 3 can be removed from the crossbar 2.

[0044] Remove the connection between the horizontal bar and the vertical column: When the eccentric quick-locking pin 11 is lifted, the second working surface, the arc-shaped surface and the first working surface successively abut against the circumferential side of the quick-locking pin adapter hole 22, and the actuating pin 112 changes from tight to loose.

[0045] The rotating shaft 115 drives the actuating pin 112 to rotate 90 degrees in the opposite direction to reset.

[0046] Remove crossbar 2 from post 1. Remove all crossbars in the same manner.

[0047] Raise or remove column 1 from the ground and organize all components for transport and storage.

[0048] In practical use, the number and layout of columns, horizontal bars, and scaffolding can be flexibly adjusted according to the size of the construction site and construction needs to build scaffolding of different shapes and heights. For example, in some interior decoration scenarios, smaller-scale scaffolding can be flexibly built according to the size of the room; while in outdoor construction, larger-scale scaffolding can be built to meet construction requirements.
