Description

Technical Field

[0001] The present invention relates to the technical field of furniture, and more particularly to a plate member connection structure and a bed frame. Background Art

[0002] Existing beds generally include a bed frame and a bed board, wherein the bed frame is composed of a crossbeam and a longitudinal beam (i.e., a supporting beam), the longitudinal beam is vertically installed between two main crossbeams, and the longitudinal beam is used to support the bed board.

[0003] Bed frames are divided into wooden bed frames and metal bed frames according to the materials. Since wooden bed frames are made of wood, which is hygroscopic and expandable, they are easily affected by moisture and expand after long-term use, especially in a humid environment. This expansion will cause the size of the wood to change, and then the originally tight connection will become loose, reducing the stability of the bed frame. Therefore, metal bed frames are more stable than wooden bed frames and are relatively widely used. However, online shopping has gradually become a common and very popular consumption pattern. Since wooden and metal bed frames are usually larger in size and weight, the transportation cost accounts for a higher proportion of the total cost. In order to maintain profits, merchants often add higher transportation costs to the sales price, which may result in the final selling price being higher than consumers' expectations. The high transportation costs make the price of bed frame products uncompetitive, especially when competing with lighter and lower-cost alternatives.

[0004] Based on this, some people have proposed that the bed frame should be made of extruded board, which is not only highly resistant to compression but also lightweight. The lightweight property of the extruded board makes it easy to transport and install. Therefore, the bed frame uses extruded board as the main beam material, which can not only meet the structural strength requirements, but also reduce the overall weight and improve the convenience of installation. However, since the extruded board is an internal hollow frame structure, the extruded board constituting the cross beam of the bed frame and the extruded board constituting the longitudinal beam of the bed frame are usually connected by screws. After long-term use, the threaded holes in the extruded board are prone to deformation. This deformation will cause the screws to be unable to be tightly fixed on the extruded board, which will cause the connection between the extruded board constituting the cross beam of the bed frame and the extruded board constituting the longitudinal beam of the bed frame to become unstable, thereby generating friction and abnormal noise when subjected to force. Summary of the invention

[0031] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0032] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0033] See also Figures 1-2As shown, a plate member connection structure provided by the present invention includes a beam body 1, a first fastener 2 and a second fastener 3.

[0034] In this embodiment, the beam body 1 is a frame structure with a hollow interior, and the beam body 1 includes a first side surface 111 and a second side surface 112 arranged opposite to the first side surface 111. A first mounting hole is arranged in the beam body 1 and passes through the first side surface 111 and the second side surface 112 along a first direction; a first fastener 2 is arranged in the first mounting hole, a first clamping portion 21 is arranged at one end of the first fastener 2, and a second clamping portion 22 is arranged at the other end of the first fastener 2, and the first clamping portion 21 contacts the first side surface 111; at least a portion of the second fastener 3 is arranged in the first fastener 2, and the second fastener 3 includes a first limiting portion 31 and a second limiting portion 32, and the first limiting portion 31 contacts the second side surface 112, and the first limiting portion 31 and the second limiting portion 32 cooperate to clamp the second clamping portion 22 and at least a portion of the beam body 1. More specifically, a threaded hole for cooperating with a fastener is arranged in the second fastener 3. By such a design, the first limiting portion 31 and the second limiting portion 32 of the second fastener 3, the first clamping portion 21 and the second clamping portion 22 of the first fastener 2 and the beam body 1 together constitute a locking point, ensuring that the force applied by the fastener can be evenly transmitted to various parts of the locking point. When the locking point is subjected to force, the force can be evenly dispersed to the front and rear sides of the second clamping portion 22 and the beam body 1, avoiding deformation due to excessive local force on the locking point, thereby reducing the risk of loosening of the fastener.

[0035] It is worth mentioning that the beam body 1 in this embodiment is an extruded part. The extrusion molding process is also called the extrusion molding process, which refers to extruding the molten plasticized plastic through the mouth gap of the mold at the head of the extruder to form a profile similar to the shape of the mold mouth.

[0036] The inventor found that although the beam body 1 is made by extrusion technology, it can greatly reduce the production cost, reduce the overall weight of the bed frame, and facilitate the reduction of transportation costs. However, in the actual production process, it faces multiple problems, such as: the bed frame uses extruded board as the main beam material, and when the extruded board constituting the cross beam of the bed frame and the extruded board constituting the longitudinal beam of the bed frame are assembled into an integral part, threaded holes are generally opened on the beam body 1, and screws are inserted into the threaded holes to fix the two together. However, since the extruded board is an internal hollow frame structure, the threaded holes in the extruded board are prone to deformation. This deformation will cause the screws to be unable to be tightly fixed on the extruded board, and then cause the connection between the extruded board constituting the cross beam of the bed frame and the extruded board constituting the longitudinal beam of the bed frame to become unstable, which is prone to friction and abnormal noise when subjected to force. Based on this, the inventor proposed a solution, namely: riveting a ram in the extruded board, and cooperating with the screw through the ram.

[0037] However, since the extruded board is hollow inside, when a ram is riveted inside the extruded board so that the ram is connected with the screw, the connection strength between the ram and the extruded board is still difficult to meet the requirements. When the locking point is subjected to force, the connection between the ram and the extruded board is prone to loosening, causing the ram to loosen and fall off, and then causing the screws connected to the ram thread to fall off.

[0038] Based on the above problems, an embodiment of the present invention provides a plate member connection structure. By adopting the above structure, the first limiting portion 31 and the second limiting portion 32 of the second fastener 3, the first clamping portion 21 and the second clamping portion 22 of the first fastener 2 and the beam body 1 together constitute a locking point, ensuring that the force applied by the fastener can be evenly transmitted to various parts of the locking point. When the locking point is subjected to force, the force can be evenly dispersed to the front and rear sides of the second clamping portion 22 and the beam body 1, avoiding the situation where the locking point is locally subjected to excessive force and deformation, thereby reducing the risk of fastener loosening.

[0039] It is worth mentioning that the first clamping portion 21 of the first fastener 2 in the present embodiment is located outside the beam body 1, and the first clamping portion 21 is in contact with the first side surface 111 of the beam body 1; the first limiting portion 31 of the second fastener 3 is located outside the beam body 1, and the first limiting portion 31 is in contact with the second side surface 112. This design effectively fixes the fastener body composed of the first fastener 2 and the second fastener 3 to the beam body 1 at multiple points. Compared with single-point fixation, this multi-point fixing method can significantly enhance the overall stability of the plate member connection structure and reduce the risk of structural deformation or damage due to external force.

[0040] Since the beam body 1, the first fastener 2 and the second fastener 3 are split structures, the first fastener 2 and the second fastener 3 can be made of harder metal materials. The materials made of the first fastener 2 and the second fastener 3 include but are not limited to carbon steel, titanium alloy, etc., and technical personnel in this field can select the corresponding material according to actual production needs.

[0041] In this embodiment, the first fastener 2 is a ram buckle, and the second fastener 3 is preferably a ram. Ram is a mechanical part and also a commonly used connection accessory, which can be connected with other parts through internal threads. Among them, ram is also called a rivet nut.

[0042] In this embodiment, the outer wall of the second fastener 3 is provided with a plurality of convex strips extending along its axial direction, and the plurality of convex strips are arranged around the outer wall of the second fastener 3, thereby constructing a deformation portion on the second fastener 3. After the second fastener 3 is inserted into the first fastener 2, the second fastener 3 is tightened by the ram gun, so that the deformation portion of the outer wall of the second fastener 3 is deformed to form a second limiting portion 32, so that the second limiting portion 32 can cooperate with the first limiting portion 31 to clamp the second clamping portion 22 and at least a portion of the beam body 1, thereby enhancing the connection strength of the beam body 1, the first fastener 2 and the second fastener 3, and preventing the second fastener 3 from falling off the beam body 1.

[0043] See also Figure 1-2 As shown, a plurality of hollow cavities extending along the second direction are provided in the beam body 1, and two adjacent hollow cavities are separated by a connecting portion 13, and the connecting portion 13 and the beam body 1 are an integral structure, and the first direction and the second direction are perpendicular to each other. In this embodiment, the second direction is the length direction of the beam body 1, and the second direction is the width direction of the beam body 1.

[0044] Specifically, a plurality of hollow cavities extending along the second direction are provided in the beam body 1. Such a design not only reduces the weight of the beam body 1, but also improves the utilization rate of materials, and can effectively reduce the production cost and transportation cost of the bed frame. Secondly, two adjacent hollow cavities are separated by a connecting portion 13, which can improve the overall bearing capacity and stability of the beam body 1.

[0045] See also Figure 2 As shown, the beam body 1 includes a main body section 11 and a bending section 12, the bending section 12 is formed by bending one side wall of the main body section 11 from the second side surface 112 toward the direction close to the first fastener 2, and the bending section 12 and the other side wall of the main body section 11 are fixedly connected by a reinforcing rib 14. Specifically, the bending section 12 abuts against the outer wall of the first fastener 2, so that the second clamping portion 22 of the first fastener 2 is pressed against the surface of the first fastener 2, so that the second clamping portion 22 can be firmly embedded in the gap between the first limiting portion 31 and the second limiting portion 32, thereby enhancing the connection firmness of the first clamping portion 21, the second clamping portion 22 and the beam body 1.

[0046] In addition, the embodiment of the present invention also provides a bed frame, see Figure 4As shown, the bed frame includes the above-mentioned plate member connection structure and the connecting piece 4. Specifically, four beam bodies 1 are provided, and the four beam bodies 1 are connected in sequence to form a rectangular frame structure. One of two adjacent beam bodies 1 is fixedly connected to the connecting piece 4 by fasteners, and the other of the two adjacent beam bodies 1 is fixedly connected to the connecting piece 4 by fasteners. The bed frame provided in this embodiment adopts a modular design, that is, each beam body 1 and the connecting piece 4 can be produced as an independent component, and then assembled into an integral part. Such a design not only simplifies the production process, but also improves the flexibility and efficiency of assembly. Secondly, such a design can effectively reduce transportation costs.

[0047] See 5 and Figure 6 As shown, the connecting piece 4 includes a first base 41 and a second base 42, and the first base 41 and the second base 42 are arranged at 90 degrees. Specifically, the first base 41 and the second base 42 are both provided with a second mounting hole corresponding to the first mounting hole, and the second mounting hole is used for inserting a fastener.

[0048] Specifically, two adjacent beam bodies 1 are fixedly connected by connecting plates 4 and fasteners, ensuring the firmness between the beam bodies 1. The fasteners (such as screws, bolts, etc.) pass through the connecting plates 4 and cooperate with the threaded holes in the second fasteners 3 to connect, so that the connection between the two beam bodies 1 is not easy to loosen when subjected to external forces.

[0049] See 5 and Figure 6 As shown, a bed frame provided by an embodiment of the present invention also includes a supporting leg 5, on which a supporting table 51 is arranged, and the supporting table 51 includes a first extension surface 511 and a second extension surface 512, one of two adjacent beam bodies 1 is erected on the first extension surface 511, and the other of the two adjacent beam bodies 1 is erected on the second extension surface 512.

[0050] Specifically, a matching portion 52 is also provided on the supporting foot 5, and the matching portion 52 includes a first extension portion 521 and a second extension portion 522 perpendicular to the first extension portion 521, one of the two adjacent beam bodies 1 is fixedly connected to the first extension portion 521 by a fastener, and the other of the two adjacent beam bodies 1 is fixedly connected to the second extension portion 522 by a fastener.

[0051] See also Figure 6 As shown, it also includes a connector 6, one end of the connector 6 is inserted into one beam body 1, and the other end of the connector 6 is inserted into another beam body 1.
