Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a cantilever structure for supporting detachable movable wooden boards. Background Technology

[0002] A detachable movable plank is a specially designed and functional plank that is connected to a load-bearing structure using special connecting devices such as hinges, pins, hooks, bolts, and nuts. The cantilever structure used to support the detachable movable plank is a mechanical structure that typically consists of a fixed part and a cantilevered part. The cantilevered part is used to support the detachable movable plank, with one end mounted to the wall and the other end cantilevered out to support the plank.

[0003] A search revealed Chinese Patent Publication No. CN118087838A, which discloses a cantilever support system for exterior walls. The cantilever support system adopts a prefabricated structure, including a truss-type load-bearing cantilever frame, a double-row coupler-type steel pipe scaffolding, unloading steel wire ropes, and wall ties. The truss-type load-bearing triangular steel cantilever frame is composed of combined triangular steel cantilever frames, serving as the foundation of the entire external protective scaffolding. The triangular steel cantilever frame uses a double-row coupler-type steel pipe scaffolding. The scaffolding includes uprights, longitudinal horizontal bars, and transverse horizontal bars; the unloading wire rope is used for unloading the upper part of each truss-type load-bearing triangular steel cantilever scaffold; the wall tie is used to ensure the stability of the truss-type load-bearing cantilever scaffold. However, the wooden planks themselves will deform due to moisture, dryness, and temperature changes, causing the middle of the planks to bulge and the edges to warp. The contact surface between the supporting structure and the planks will shift due to its smoothness, which will disrupt the balance of the planks and eventually cause them to tip over. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cantilever structure for supporting detachable movable wooden boards, aiming to improve the problem in the prior art where the contact surface between the support structure and the wooden board will shift due to its smoothness, which will disrupt the balance of the wooden board and eventually cause it to tip over.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cantilever structure for supporting detachable movable wooden boards, comprising multiple elongated short pieces, each of which has a triangular plate two fixedly connected to an adjacent side of its outer wall, a serrated strip one fixedly connected to the top of the triangular plate two, multiple triangular plates one fixedly connected at equal intervals to the rear side of the outer wall of the triangular plate two, and serrated strips two fixedly connected to the rear side of the outer wall of each triangular plate one, multiple bolt slots equally spaced on the outer wall of the elongated short pieces, each bolt slot having a threaded connection to a bolt one, and multiple pressing mechanisms equally spaced on the front side of the outer wall of the elongated short pieces, the pressing mechanisms being used to press down and fix the wooden board stored on the top of the serrated strip one.

[0006] As a further description of the above technical solution:

[0007] The pressing mechanism includes an elongated support plate, which is equidistantly installed on the front side of the outer wall of the elongated short piece. A threaded rod is rotatably connected to the top of the elongated support plate, and a lower pressure plate is threadedly connected to the outer wall of the threaded rod. An inner slider guide plate is fixedly connected to the top of the elongated support plate, and a worm gear is fixedly connected to the bottom end of the threaded rod. A support short plate is fixedly connected to the bottom of the left side of the elongated support plate, and a worm is rotatably connected to the middle of the outer wall of the support short plate. The worm is meshed with the worm gear.

[0008] As a further description of the above technical solution:

[0009] A circular throttle is fixedly connected to the left end of the outer wall of the worm gear.

[0010] As a further description of the above technical solution:

[0011] An anti-slip sleeve is fixedly connected to the outer wall of the circular throttle.

[0012] As a further description of the above technical solution:

[0013] A hollow box is fixedly connected to the bottom of the elongated support plate on the left, and a drawer is slidably connected inside the hollow box.

[0014] As a further description of the above technical solution:

[0015] A handle is fixedly connected to the left side of the outer wall of the drawer, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0016] As a further description of the above technical solution:

[0017] Multiple sealing rings are fixedly connected at equal intervals on the front side of the outer wall of the bolt groove.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the elongated short piece on the left is threaded with a bolt two, and the outer wall of the bolt two is threaded with multiple warning signs at equal intervals.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the triangular structure of the triangular plate enhances the rigidity and stability of the cantilever and reduces deformation. The serrated strip increases the friction between the cantilever and the placed wooden board, preventing the wooden board from sliding. This avoids the problem that the contact surface between the support structure and the wooden board will shift due to smoothness, which would disrupt the balance of the wooden board and ultimately cause it to tip over.

[0022] 2. In this utility model, the worm gear is rotated to drive the worm wheel, which is fixed at the bottom of the threaded rod, thereby causing the threaded rod to rotate. The threaded rod is threadedly connected to the lower pressure plate, so the lower pressure plate can move up and down along the outer wall of the threaded rod. The inner slider guide plate ensures that the lower pressure plate moves vertically and rises and falls smoothly until it contacts the wooden board and applies pressure, fixing the wooden board on the sawtooth strip, improving friction and stability, thereby reducing the probability of the wooden board sliding and tipping over.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides a cantilever structure for supporting detachable movable wooden boards, comprising multiple elongated short pieces 1. Triangular plates 2 5 are fixedly connected to adjacent sides of the outer wall of each elongated short piece 1. A serrated strip 1 6 is fixedly connected to the top of each triangular plate 2 5. Multiple triangular plates 1 4 are fixedly connected at equal intervals to the rear side of the outer wall of each triangular plate 2 5. A serrated strip 2 14 is fixedly connected to the rear side of the outer wall of each triangular plate 1 4. Multiple bolt grooves 17 are equidistantly provided on the outer wall of each elongated short piece 1. Bolts 1 3 are threaded into the bolt grooves 17. Multiple pressing mechanisms 2 are equidistantly installed on the front side of the outer wall of each elongated short piece 1. The pressing mechanisms 2 are used to press down and fix the wooden board placed on the top of the serrated strip 1 6. A circular handle 10 is fixedly connected to the left end of the outer wall of the worm gear 202. The circular handle 10 facilitates the operation of the worm gear 202 by the operator. An anti-slip sleeve 1 9 is fixedly connected to the outer wall of the circular handle 10. The anti-slip sleeve 1 9 prevents the operator from slipping their hand when turning the circular handle 10.

[0032] Specifically, multiple elongated short pieces 1 are connected and fixed adjacently via bolt slots 17 and bolts 3, forming the main frame of the cantilever. This structural design allows the entire cantilever structure to be assembled without welding, using only simple bolt connections. It is easy to process, disassemble, and adjust. Triangular plates 25 and 4, fixedly connected to adjacent sides of the outer wall of the elongated short pieces 1, form a triangular structure. Due to the stability of triangles, this design enhances the overall rigidity and stability of the cantilever structure, enabling it to better withstand loads and reduce the possibility of deformation. The serrated strip 6 at the top of triangular plate 25 and the serrated strip 14 on the rear side of the outer wall of triangular plate 4 form a toothed structure. When detachable movable wooden boards or pallets are directly placed on these toothed edges, the serrated strip 6 increases the friction between the contact surface and the wooden board. The friction force increases with the weight load, resulting in stronger interlocking between the saw teeth 6 and the wooden board, and better anti-slip effect. This effectively prevents the wooden board from sliding or shifting on the support structure. Since the wooden board rests directly on the toothed edge without the need for bolting, disassembly or forklift transport can be performed simply by lifting the wooden board or pallet from the toothed edge. This makes operation convenient and facilitates replacement or adjustment of the wooden board or pallet. The material is simple, using 3mm thick galvanized steel plate (Q235B), resulting in low material cost. A circular handle 10 is fixedly connected to the left end of the outer wall of the worm gear 202, allowing workers to easily rotate the worm gear 202. An anti-slip sleeve 9 is fixedly connected to the outer wall of the circular handle 10, preventing workers from slipping their hands when rotating the handle.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The pressing mechanism 2 includes an elongated support plate 201, which is equidistantly installed on the front side of the outer wall of the elongated short piece 1. A threaded rod 205 is rotatably connected to the top of the elongated support plate 201, and a lower pressure plate 204 is threadedly connected to the outer wall of the threaded rod 205. An inner slider guide plate 203 is fixedly connected to the top of the elongated support plate 201. Worm gears 207 are fixedly connected to the bottom ends of the threaded rods 205. A support short plate 206 is fixedly connected to the bottom of the left elongated support plate 201. A worm gear 202 is rotatably connected to the middle of the outer wall of the short plate 206. The worm gear 202 is meshed with the worm wheel 207. A hollow box 16 is fixedly connected to the bottom of the long support plate 201 on the left side. A drawer 15 is slidably connected inside the hollow box 16. The drawer 15 can conveniently store spare parts. A handle 12 is fixedly connected to the left side of the outer wall of the drawer 15. The handle 12 can facilitate the operation of the drawer 15 by the staff. An anti-slip sleeve 13 is fixedly connected to the outer wall of the handle 12.

[0034] Specifically, by rotating the worm 202, which is meshed with the worm wheel 207, the rotation of the worm 202 drives the worm wheel 207 to rotate. Since the worm wheel 207 is fixed to the bottom end of the threaded rod 205, its rotation drives the threaded rod 205 to rotate. The threaded rod 205 is threadedly connected to the lower pressure plate 204, so when the threaded rod 205 rotates, the lower pressure plate 204 moves up and down along the outer wall of the threaded rod 205. During this movement, the lower pressure plate 204 is restricted by the inner slider guide plate 203 and can only move in the vertical direction. Ensure the lower pressure plate 204 rises and falls smoothly until it contacts the surface of the wooden board and applies pressure, pressing the wooden board down and fixing it on the sawtooth strip 6. This increases the friction and stability between the wooden board and the cantilever structure. A hollow box 16 is fixedly connected to the bottom of the long support plate 201 on the left side. A drawer 15 is slidably connected inside the hollow box 16. The drawer 15 can easily store spare parts for daily use. A handle 12 is fixedly connected to the left side of the outer wall of the drawer 15. The handle 12 makes it easy for workers to open and close the drawer 15. An anti-slip sleeve 2 13 is fixedly connected to the outer wall of the handle 12.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Multiple sealing rings 11 are fixedly connected at equal intervals on the front side of the outer wall of the bolt groove 17. The sealing rings 11 can enhance the sealing between the bolt 13 and the bolt groove 17 and prevent impurities from entering. The bolt 2 7 is threadedly connected to the front side of the outer wall of the long short piece 1 on the left. Multiple warning signs 8 are threadedly connected to the outer wall of the bolt 2 7 at equal intervals. The warning signs 8 can remind the staff of the precautions for using the device, thereby reducing the probability of accidents.

[0036] Specifically, multiple sealing rings 11 are fixedly connected at equal intervals on the front side of the outer wall of the bolt groove 17. The sealing rings 11 can enhance the sealing between the bolt 13 and the bolt groove 17 and prevent impurities from entering. The front side of the outer wall of the left long piece 1 is threaded with a bolt 2 7. Multiple warning signs 8 are threadedly connected at equal intervals on the outer wall of the bolt 2 7. The warning signs 8 can remind the staff of the precautions for using the device, thereby reducing the probability of accidents.

[0037] Working principle: Multiple long and short pieces 1 are connected and fixed to each other through bolt slots 17 and bolts 3, forming the main frame of the cantilever. This structural design allows the entire cantilever structure to be assembled without welding, using only simple bolt connections. It is easy to process, disassemble, and adjust. Triangular plates 25 and 14, fixedly connected to adjacent sides of the outer wall of the long and short pieces 1, form a triangular structure. Due to the stability of triangles, this design enhances the overall rigidity and stability of the cantilever structure, enabling it to better withstand loads and reduce the possibility of deformation. The serrated strip 16 at the top of triangular plate 25 and the serrated strip 14 on the rear side of the outer wall of triangular plate 14 form a toothed structure. When detachable movable wooden boards or pallets are directly placed on these... When the serrated edge is in contact with the wooden board, the serrated strip 6 increases the friction between the serrated strip 6 and the wooden board. The greater the load, the stronger the interlocking action between the serrated strip 6 and the wooden board, and the better the anti-slip effect. This effectively prevents the wooden board from sliding and shifting on the support structure. Since the wooden board is directly placed on the serrated edge, there is no need to bolt it. When it needs to be disassembled or transported by forklift, you only need to lift the wooden board or pallet from the serrated edge. The operation is convenient and it is also easy to replace or adjust the wooden board or pallet. The material selection is simple and can use 3mm thick galvanized steel plate, material Q235B, which is low in material cost. This avoids the problem that the contact surface between the support structure and the wooden board will shift due to the smoothness, which would destroy the balance of the wooden board and eventually cause the wooden board to tip over.

[0038] By rotating the worm 202, which is meshed with the worm wheel 207, the rotation of the worm 202 drives the worm wheel 207 to rotate. Since the worm wheel 207 is fixed to the bottom of the threaded rod 205, the rotation of the worm wheel 207 will drive the threaded rod 205 to rotate. The threaded rod 205 is threadedly connected to the lower pressure plate 204. Therefore, when the threaded rod 205 rotates, the lower pressure plate 204 will move up and down along the outer wall of the threaded rod 205. During the movement, the lower pressure plate 204 is restricted by the inner slider guide plate 203 and can only move in the vertical direction, ensuring that the lower pressure plate 204 rises and falls smoothly until the lower pressure plate 204 contacts the surface of the wooden board and applies pressure, pressing the wooden board down and fixing it on the sawtooth strip 6. This increases the friction and stability between the wooden board and the cantilever structure, thereby reducing the probability of the wooden board sliding and tipping over.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
