Description

Technical Field

[0001] This invention relates to the field of woodworking clamps technology, specifically a flexible, non-marking bamboo and wood spring clamp. Background Technology

[0002] A-frame spring clips are lightweight clamping tools with a symmetrical "A"-shaped structure. They consist of two one-piece molded clamping arms, a top hinge pin assembly, a bottom clamping end, and a torsion spring fitted onto the hinge pin. Spring clips are mostly made of metal or hard plastic. Metal clips offer high strength and stable clamping force, making them suitable for woodworking, handcrafting, and other similar applications.

[0003] However, when spring clips are used to clamp high-end or fragile items such as wooden furniture, lacquered products, ancient books and papers, and high-end fabrics, the clamping ends are often made of metal or hard plastic. Their surfaces are often designed with narrow surfaces, serrated edges, or simple raised structures. This not only results in a small contact area with the clamped item, but the material of the clamping end is also harder than the item itself, easily leaving indentations. These indentations severely damage the item's appearance and collectible value. Furthermore, during opening and closing or clamping, the sharp edges of the clamping ends can easily scratch the item. Even if the clamping ends are machined into a smooth structure without sharp edges, sharp edges will inevitably reappear after long-term repeated clamping and friction. While using plastic or additional rubber anti-slip pads on the clamping ends can reduce the probability of scratches to some extent, under prolonged clamping and pressure, the molecular chains of the plastic or rubber can easily interpenetrate with the clamped item, leading to adhesion and fusion, which can also cause secondary damage to high-end and fragile items. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a flexible, non-marking bamboo and wood spring clip, which has the advantages of a large contact area at the clamping end, material hardness that is compatible with the clamped item, and no sharp edges, thus solving the problem of indentations and scratches when clamping fragile items.

[0005] (II) Technical Solution To achieve the aforementioned goals of a large contact area at the clamping end, material hardness adapted to the clamped item, and absence of sharp edges, the present invention provides the following technical solution: a bamboo-wood flexible, traceless spring clip, comprising two sets of clamping arms, each clamping arm having a connecting seat fixedly mounted on it. The two sets of clamping arms are rotatably connected via the connecting seats, and a pin is provided between the two sets of connecting seats. A torsion spring is coaxially mounted on the pin, and spring arms are provided at both ends of the torsion spring, with each spring arm connecting to one of the two sets of clamping arms respectively. The clamping arm has a clamping end on one side with the connecting seat as the dividing point, and a force-applying end on the other side. The clamping arm is made of continuous bamboo-wood material, which includes bamboo node segments and internode segments. The clamping end and the force-applying end are internode segments, and the connection position between the clamping arm and the connecting seat is a bamboo node segment.

[0006] Preferably, the inner side of the clamping arm is machined with a mounting groove, the location of which corresponds to the bamboo joint section of the bamboo material, and the connecting seat is fixedly installed in the mounting groove.

[0007] Preferably, bolts are fixedly assembled between the connecting seat and the mounting groove; pin holes are provided on the connecting seat, and the pins are coaxially inserted into the pin holes on the two sets of connecting seats.

[0008] Preferably, the connector and the pin are made of metal.

[0009] Preferably, the surface of the clamping end is machined with anti-slip texture.

[0010] Preferably, a groove is formed on the inner side of the clamping arm to accommodate and restrict the spring arm, and the length of the groove is greater than the vertical projection length of the spring arm on the clamping arm.

[0011] Preferably, the clamping arm is formed by pressing together two or more sets of continuous bamboo and wood materials in the transverse direction.

[0012] Preferably, the clamping end is cut with continuous sheet-like elastic sheets along the contour direction from its upper end surface to its lower end surface, and the connection point between the elastic sheet and the upper end surface is broken. The elastic sheet is reconnected to the cut upper end surface, and the reconnection point between the elastic sheet and the upper end surface is away from the break point of the upper end surface sheet along the contour direction from the upper end surface to the lower end surface, so that the elastic sheet and the clamping end form an elastic protrusion deformation facing the clamped object; and in the clamping state, the elastic sheet adheres to the surface of the clamped object after being squeezed by the clamped object to form a surface contact structure.

[0013] Preferably, a connecting buckle is provided between the elastic sheet and the upper surface; and the surface of the elastic sheet is processed with anti-slip texture.

[0014] Preferably, an airbag is fixedly installed between the elastic sheet and the lower end surface. In the clamping state, the airbag is squeezed by the elastic sheet, causing the side of the airbag that is not squeezed to expand and deform toward the clamped object, thereby pushing the elastic sheet at the corresponding position to synchronously adhere to the surface of the clamped object.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a flexible, traceless bamboo and wood spring clip, which has the following beneficial effects: 1. This bamboo and wood flexible non-marking spring clip utilizes the combination of bamboo and wood materials with bamboo joint sections. The connection between the clip arm and the connecting seat is set at the bamboo joint section. The high density and high strength of the bamboo joint section stably bear the tension of the torsion spring and the hinge force, avoiding the deformation of the bamboo and wood material connection point during clamping. The clamping end and the force-applying end are set at the internode section. The good toughness brought by the longitudinal continuous fibers of the bamboo in the internode section is adapted to the slight deformation during clamping, allowing the clamping end to form surface contact with the clamped object. At the same time, since the entire clip arm is made of bamboo and wood material, its hardness is compatible with the hardness of high-grade and fragile items. Combined with the flexible deformation characteristics of the internode section, the clamping pressure is effectively dispersed, effectively solving the problem of indentation and scratches caused by the small contact area and large hardness difference between the clamped metal or hard plastic clip ends and the clamped object.

[0016] 2. This bamboo and wood flexible, non-marking spring clip utilizes the combined use of an elastic sheet structure and a clamping end structure. By leveraging the length redundancy created by the reconnection of the elastic sheet to the upper surface after disconnection, and combining this with the flexibility of the internode sections, the elastic sheet undergoes an elastic protrusion deformation towards the clamped object. This allows the elastic sheet to replace the clamping end in contact with the object during clamping. The flexibility of the bamboo and wood internode sections enables the elastic sheet to self-adaptively deform, further optimizing the surface contact effect and more effectively dispersing clamping pressure. Compared to hard clamping ends, this significantly reduces the problem of indentations and scratches. Simultaneously, the connecting buckle at the connection point allows the elastic sheet to rotate slightly left and right relative to the upper surface, thus counteracting the effects of clamp arm swaying and preventing displacement or rotation between the elastic sheet and the clamped object, greatly reducing the risk of scratches caused by collisions or other accidents.

[0017] 3. This bamboo and wood flexible traceless spring clip, through the combined use of an elastic sheet structure and an air bladder structure, allows the elastic sheet to produce adaptive deformation that adheres more closely to the clamped object. Furthermore, the flexible deformation of the elastic sheet and the expansion of the air bladder can create a dual pressure dispersion effect, thereby greatly reducing the probability of indentations and scratches, and providing more comprehensive protection for high-end and fragile items.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-4A flexible, traceless bamboo and wood spring clip includes two sets of clamping arms 1. A connecting seat 2 is fixedly mounted on each clamping arm 1. The connecting seat 2 has a block-shaped structure, with a flat mounting surface on one side facing the clamping arm 1 that fits against the inner surface of the clamping arm 1. A pin hole, adapted to a pin 21, is opened on the side away from the clamping arm 1. The pin hole is a through-hole structure with a smooth inner wall. The two sets of clamping arms 1 are rotatably connected by the connecting seat 2, and a pin 21 is provided between the two sets of connecting seats 2. A torsion spring 22 is coaxially mounted on the pin 21. Spring arms 221 are provided at both ends of the torsion spring 22, and each end of the spring arms 221 connects to one of the two sets of clamping arms 1. Both ends of the spring arms 221 are bent towards the clamping arm 1 to form a fitting section. The fitting section fits tightly against the inner surface of the clamping arm 1, and a matching limiting groove is reserved on the inner surface of the clamping arm 1 corresponding to the fitting point of the spring arm 221 to ensure that the spring arm 221 does not shift under stress. The clamping arm 1 has a clamping end 11 on one side, with the connecting seat 2 as the dividing line, and a force-applying end 12 on the other side. The clamping arm 1 is made of continuous bamboo-wood material, cut from a single piece of bamboo, retaining the bamboo node section 3 and internode section 4. The bamboo node section 3 is the naturally formed raised portion during bamboo growth, and the internode section 4 is the straight portion between two adjacent bamboo nodes. The length direction of the clamping arm 1 is consistent with the longitudinal fiber direction of the bamboo. The bamboo-wood material includes the bamboo node section 3 and the internode section 4, such as... Figure 3 As shown, the clamping end 11 and the force-applying end 12 are internode sections 4, and the connection position between the clamping arm 1 and the connecting seat 2 is the bamboo joint section 3. The clamping end 11 and the force-applying end 12 are set as internode sections 4, and the connection position with the connecting seat 2 is set as the bamboo joint section 3 because the bamboo joint section 3 has a higher fiber density and a more compact structure, which has a stronger load-bearing capacity and resistance to deformation. It can withstand the tension of the torsion spring 22 and the force of the hinge. The longitudinal fibers of the internode section 4 are continuous and have excellent toughness, which can adapt to slight deformation during the clamping process and avoid damage to the clamped object due to excessive rigidity.

[0022] Please see Figures 1-4The inner side of the clamping arm 1 is machined with a mounting groove 13, the location of which corresponds to the bamboo joint section 3 of the bamboo material. The connecting seat 2 is fixedly installed in the mounting groove 13. The mounting groove 13 is located on the inner side of the clamping arm 1 and has a rectangular groove structure. The depth of the groove is adapted to the thickness of the connecting seat 2. The length and width of the mounting groove 13 are slightly larger than the size of the connecting seat 2 to ensure that the connecting seat 2 can be smoothly inserted. The bottom of the mounting groove 13 is polished to ensure the fit between the connecting seat 2 and the bottom of the groove. The location of the mounting groove 13, corresponding to the bamboo joint section 3 of the bamboo material, can withstand the fastening force when the connecting seat 2 is fixed and the force during the subsequent clamping process, preventing cracking or deformation due to insufficient strength at the location of the mounting groove 13. Bolts are used to fix the connecting seat 2 and the mounting groove 13. The connecting seat 2 has pin holes, and the pins 21 are coaxially inserted into the pin holes on the two sets of connecting seats 2. The connecting seat 2 has a through bolt hole on one end face facing the mounting groove 13. A matching threaded hole is also provided at the corresponding position on the bottom of the mounting groove 13. The bolt passes through the threaded hole in the mounting groove 13 and is threaded into the bolt hole of the connecting seat 2. The head of the bolt is embedded in the countersunk hole on the outer side of the clamping arm 1. The pin hole on the connecting seat 2 is a cylindrical through hole, and the pin 21 is a cylindrical structure with its outer diameter transitionally fitting the inner diameter of the pin hole, ensuring that the pin 21 can be smoothly inserted into the pin hole without significant gaps. The connecting seat 2 and the pin 21 are made of metal. The connecting seat 2 is preferably made of 304 stainless steel, and the pin 21 is made of brass. Both undergo surface finishing; the surface of the connecting seat 2 is passivated for rust prevention, and the surface of the pin 21 is polished smooth. The clamping end 11 has anti-slip textured surfaces. The anti-slip texture adopts a horizontal continuous stripe structure. The inner side of the clamping arm 1 is provided with a groove 121 to accommodate and restrict the spring arm 221. The length of the groove 121 is greater than the vertical projection length of the spring arm 221 on the clamping arm 1, and its width is adapted to the width of the spring arm 221. The groove wall is smoothed. The length of the groove 121 is designed to be greater than the vertical projection length of the spring arm 221 on the clamping arm 1 to provide sufficient room for the spring arm 221 to move during the deformation of the torsion spring 22, avoiding hard collision or jamming between the spring arm 221 and the end of the groove 121. The clamping arm 1 is formed by pressing together two or more sets of continuous bamboo and wood materials in the transverse direction. The clamping arm 1 is formed by pressing together multiple sets of bamboo and wood materials in the transverse direction. Each set of bamboo and wood materials is cut into flat sheets along the longitudinal fiber direction of the bamboo. When stacked, the fiber directions of adjacent sets of materials are cross-distributed. Before pressing, natural bamboo glue is evenly applied to the contact surface of each set of materials. Then, the materials are tightly bonded together by a low-temperature hot pressing process. After pressing, the entire surface of the clamping arm 1 is polished. Because a single bamboo clamp arm 1 is prone to deformation or cracking under lateral force during clamping, multiple sets of bamboo and wood materials are cross-pressed together, and the fibers of each set of materials reinforce each other, forming a mechanical property similar to a composite structure, thus avoiding deformation of the main body of the clamp arm 1 due to lateral force during clamping.

[0023] Please see Figures 1-4 When in use, when the force-applying end 12 is subjected to external force, the two sets of clamping arms 1 rotate relative to each other around the pin 21 on the connecting seat 2. During this process, the torsion spring 22 sleeved on the pin 21 is compressed and stores elastic potential energy. When the force-applying end 12 is released, the elastic potential energy of the torsion spring 22 is released, and the spring arms 221 at both ends drive the two sets of clamping arms 1 to reset, so that the clamping end 11 closes in the middle to realize the clamping action. The clamping arm 1 is made of naturally continuous bamboo and wood material along its length. The connection position between the clamping arm 1 and the connecting seat 2 corresponds to the bamboo joint section 3 of the bamboo and wood material. The bamboo joint section 3, with its high density and high strength, can stably bear the tension of the torsion spring 22 and the force of the hinge, thus ensuring that the connection position between the clamping arm 1 and the connecting seat 2 is not easily deformed. The clamping end 11 and the force-applying end 12 of the clamping arm 1 correspond to the internode sections 4 on both sides of the bamboo joint section 3. The internode sections 4 have good toughness due to the longitudinal continuous fibers of the bamboo, which can adapt to the slight deformation of the clamping end 11 and the force-applying end 12 during the clamping process. At the same time, the internode sections 4 can also provide a comfortable touch for the force-applying end 12. Furthermore, the clamping arm 1 is formed by pressing two or more sets of continuous bamboo and wood materials laterally, which can further improve the lateral bending strength and tear resistance of the clamping arm 1, thereby preventing the main body of the clamping arm 1 from deforming due to lateral force during clamping. During use, the hardness of bamboo and wood materials is similar to that of high-end and easily damaged items such as wooden furniture and painted products. Combined with the good flexible deformation characteristics of the intersegment section 4 of the clamping end 11, the clamping end 11 can form a surface contact with the clamped object, effectively dispersing the clamping pressure. This avoids the indentations and scratches caused by the small contact area and high hardness of traditional metal or hard plastic clamping ends 11, thus ensuring the stability and scratch-free effect of the clamping process.

[0024] Example 2 Please see Figures 5-7The clamping end 11 has continuous sheet-like elastic sheets 5 cut along the contour direction from its upper surface 111 to its lower surface 112. The connection point between the elastic sheet 5 and the upper surface 111 is broken, and the elastic sheet 5 is reconnected to the cut upper surface 111. The reconnection point between the elastic sheet 5 and the upper surface 111 is away from the break point of the upper surface 111 along the contour direction from the upper surface 111 to the lower surface 112, so that the elastic sheet 5 and the clamping end 11 form an elastic protrusion deformation facing the clamped object. The elastic sheet 5 is processed by cutting along the contour direction from the upper surface 111 to the lower surface 112 of the clamping end 11. During cutting, only the initial connection point between the elastic sheet 5 and the upper surface 111 is broken, while the connection integrity between the elastic sheet 5 and the lower surface 112 is preserved, so that the elastic sheet 5 has a sheet-like structure with one end fixed and the other end movable. When the elastic sheet 5 is reconnected to the cut upper surface 111, a fitted fixing method is adopted. The reconnection point is far away from the initial disconnection position along the contour direction, ensuring that the elastic sheet 5 retains sufficient length redundancy. Because the traditional clamping end 11 is a rigid whole, it cannot adapt to clamped objects with different contours. The elastic sheet 5 formed by cutting, combined with the length redundancy design, can naturally form an elastic protrusion deformation towards the clamped object by taking advantage of the flexible characteristics of the inter-segment section 4. This allows the elastic sheet 5 to contact the clamped object first during the clamping process. Through its own elastic deformation, it adaptively fits the surface of the clamped object, forming a full surface contact. Compared with the rigid clamping end 11, it can more effectively disperse the clamping pressure and avoid the generation of indentations and scratches. A connecting buckle 51 is provided between the elastic sheet 5 and the upper surface 111. The connecting buckle 51 adopts a positioning pin adapted to the material of the elastic sheet 5. One end of it is fitted and fixed to the upper surface 111, and the other end is fitted and connected to the reconnection point of the elastic sheet 5. In addition, the surface of the elastic sheet 5 is processed with anti-slip texture. The anti-slip texture features a fine horizontal stripe structure.

[0025] Please see Figures 5-7The elastic sheet 5 is cut along the contour direction from the upper end surface 111 to the lower end surface 112 of the clamping end 11 to form a continuous sheet structure. Its length is consistent with the total contour length from the cut point of the upper end surface 111 to the end cut point of the lower end surface 112. However, when the elastic sheet 5 is reconnected to the cut upper end surface 111 and the reconnection point is far away from the cut point of the upper end surface 111 along the cutting direction, a length redundancy will be formed where the length of the elastic sheet 5 is greater than the contour distance between the reconnection point and the end cut point of the lower end surface 112. Furthermore, the inter-segment section 4 used in the clamping end 11 has flexible characteristics, which causes the elastic sheet 5 and the clamping end 11 to form an elastic protrusion deformation towards the clamped object, i.e., the contact position of the two sets of clamping arms 1 clamping end 11. This elastic protrusion deformation will cause the elastic sheet 5 to... It can replace the clamping end 11 to contact and be squeezed the clamped object. At the same time, with the flexible characteristics of the bamboo and wood internode section 4, the elastic sheet 5 will undergo adaptive deformation and completely adhere to the surface of the clamped object to form a surface contact structure. This effectively disperses the clamping pressure and avoids the indentations and scratches caused by the traditional hard clamping end 11. The anti-slip texture processed on the surface of the elastic sheet 5 increases the contact friction to prevent slippage. Meanwhile, the connecting buckle 51 set at the connection point allows the elastic sheet 5 to rotate slightly left and right relative to the upper surface 111. When the clamping arm 1 as a whole shakes relative to the clamped object, this rotation can offset the effect of the shaking and prevent displacement or rotation between the elastic sheet 5 and the clamped object. This effectively reduces the risk of the clamping arm 1 rotating due to collisions and other reasons, which would cause scratches on the surface of the clamped object.

[0026] Example 3 Please see Figures 8-9 An airbag 52 is fixedly installed between the elastic sheet 5 and the lower surface 112. The airbag 52 is a flexible structure filled with gas, and its shape matches the contour of the back of the elastic sheet 5. The edges are sealed, and the interior is filled with inert gas to ensure expansion stability. During installation, one side of the airbag 52 is completely adhered and fixed to the back of the elastic sheet 5 using natural environmentally friendly adhesive, and the other side is adhered and fixed to the lower surface 112 of the clamping end 11. After fixing, the airbag 52 is in a naturally inflated state, without applying any additional force to the elastic sheet 5. In the clamping state, the airbag 52 is compressed by the elastic sheet 5, causing the uncompressed side of the airbag 52 to expand and deform towards the clamped object, thereby pushing the corresponding position of the elastic sheet 5 to simultaneously adhere to the surface of the clamped object.

[0027] Please see Figures 8-9Based on the structure of Embodiment 2, when an airbag 52 is fixedly installed between the elastic sheet 5 and the lower end surface 112 of the clamping end 11, the squeezing force of the object being clamped on the elastic sheet 5 during the clamping process is synchronously transmitted to the airbag 52, causing the squeezed side of the airbag 52 to contract and deform, while the unsqueezed side expands and deforms towards the object being clamped. The expanded airbag 52 acts on the corresponding position of the elastic sheet 5 through the generated elastic thrust, prompting the elastic sheet 5 to overcome its own local rigidity limitations and undergo more sufficient adaptive deformation, such as... Figure 9 As shown, this ensures that the elastic sheet 5 completely adheres to the surface of the object being clamped, forming a gapless surface contact structure. This achieves dual pressure dispersion through the flexible deformation of the elastic sheet 5 and the buffer expansion of the airbag 52, further reducing the probability of indentations and scratches. Furthermore, the anti-slip texture on the surface of the elastic sheet 5 and the enhanced adhesion pressure brought by the airbag 52 greatly improve the anti-slip stability during clamping.
