Description

Technical Field

[0001] This invention relates to the field of bed frame technology, and in particular to a bed board connection structure and a bed frame. Background Technology

[0002] Bed frame slats typically consist of profiles, plastic connectors, and wooden boards. The profiles are often made of aluminum, while the boards can be straight or curved. The ends of the wooden boards are fitted into plastic connectors, which are then attached to the profiles. Together, the profiles form the supporting frame. This type of slatted frame usually includes two rows of wooden boards, each row consisting of multiple spaced-apart boards, arranged in a rib-like pattern to provide good ventilation and support.

[0003] In the prior art, patent document CN213550795U discloses a bed frame with a replaceable headboard. This structure includes a bed frame, which consists of side panels, support rods, four-hole corner brackets, and a crossboard. The side panels and crossboard are fixedly connected by four-hole corner brackets and locking bolts. The bed board includes a rectangular frame, a support plate, two-hole small corner brackets, and a wooden board. The entire structure is placed on the four-hole corner brackets via the rectangular frame and fixed using multiple sets of corner brackets and locking bolts. While this structure allows for a replaceable headboard, its connection relies heavily on a large number of locking bolts and corner bracket components.

[0004] However, the existing wooden panels require multiple four-hole brackets and locking bolts to be individually fixed to the side and cross panels. Due to the large number of panels, repeated bolt tightening is necessary during assembly, making the installation process cumbersome and inefficient. Furthermore, relying solely on bolt tightening is prone to loosening under long-term load and vibration, affecting the overall stability of the bed frame. Summary of the Invention

[0005] In order to address the technical deficiencies mentioned in the background art, the present invention aims to provide a bed board connection structure and bed frame. By using the protrusion at the bottom of the plastic connecting sleeve to engage with the pre-punched elastic clip on the profile, not only are many bolt locking steps eliminated, significantly improving installation efficiency, but the elastic abutment of the elastic clip also effectively prevents the connection structure from loosening, thus solving the problems of inconvenient installation and easy loosening in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bed board connection structure includes a profile, a plastic connecting sleeve, and a wooden board. The profile has a plurality of connecting holes spaced apart along its length. The inner wall of each connecting hole is connected to a downwardly bent elastic card. The plastic connecting sleeve has at least one socket for inserting the wooden board. The bottom of the plastic connecting sleeve has a downwardly extending protrusion corresponding to each socket. The protrusion is inserted into the connecting hole and elastically abuts against the elastic card.

[0007] Specifically, the protrusion includes a columnar connecting part connected to the bottom surface of the plastic connecting sleeve and a tapered insertion part connected to the lower end of the columnar connecting part, and the surface of the columnar connecting part is provided with several annular flanges.

[0008] Specifically, the top surface of the plastic connecting sleeve is provided with several reinforcing ribs, the top surface of the socket is concave, and the bottom surface of the socket is concave.

[0009] Specifically, the plastic connecting sleeve has two protrusions, and the elastic force directions of the two elastic cards corresponding to the two protrusions on the same plastic connecting sleeve are opposite.

[0010] Specifically, the plastic connector sleeve has two opposite insertion ports, into which two pieces of wood are inserted respectively, and the protrusion is located between the two insertion ports.

[0011] A bed frame, comprising: Bed frame; The bed board connection structure has the profile connected to the bed frame, and the wooden boards are spaced apart on the inner side of the bed frame.

[0012] Specifically, the bed frame includes two crossbeams, two longitudinal beams, and right-angle connecting seats for connecting the crossbeams and the longitudinal beams. A middle beam connects the two longitudinal beams, and the profile is fixed on both the crossbeams and the middle beam.

[0013] Specifically, the crossbeam and the profile are integrally formed, and the intermediate beam and the profile are integrally formed.

[0014] Specifically, the intermediate beam is provided with sliding plates and self-tapping screws at both ends, and the self-tapping screws are threadedly connected to the longitudinal beam after passing through the sliding plates.

[0015] Specifically, the bed frame is provided with support components at its four corners. The support components include a first mounting base fixed to the bottom of the crossbeam, a second mounting base fixed to the bottom of the longitudinal beam, an inclined support beam connecting the first mounting base and the second mounting base, and a support foot fixed to the lower end of the inclined support beam by bolts.

[0016] Beneficial effects: This application utilizes a snap-fit ​​mechanism between a protrusion at the bottom of the plastic connecting sleeve and an elastic clip inside the profile connecting hole. During installation, after the wooden board is placed inside the plastic connecting sleeve, simply pressing down allows the protrusion to insert into the connecting hole and be elastically secured by the clip, eliminating the need for bolts or tools and significantly improving bed frame assembly efficiency. The elastic clip, formed from bent scrap material from profile punching, provides continuous and stable elastic pressure, effectively preventing the protrusion from loosening and enhancing the anti-loosening performance and load-bearing capacity of the connection structure. Simultaneously, the combination of the double-opening plastic connecting sleeve and the single row of connecting holes reduces the number of profile punching holes, simplifies the production process, lowers manufacturing costs, and ensures a stable and reliable overall structure, extending the service life of the bed frame.

Detailed Implementation

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0022] In this application, unless otherwise expressly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components, unless otherwise expressly limited.

[0023] Example 1 Please refer to Figures 1 to 9This embodiment discloses a bed board connection structure, including a profile 10, a plastic connecting sleeve 20 and a wooden board 30. The profile 10 has a plurality of connecting holes 11 spaced apart along its length. The inner wall of the connecting holes 11 is connected to a downwardly bent elastic card 12. The plastic connecting sleeve 20 has at least one insertion port 21 for inserting the wooden board 30. The bottom of the plastic connecting sleeve 20 has a downwardly extending protrusion 22 corresponding to each insertion port 21. The protrusion 22 is inserted into the connecting hole 11 and elastically abuts against the elastic card 12. During installation, insert both ends of the wooden board 30 into the slots 21 of the plastic connecting sleeve 20, then align the protrusion 22 at the bottom of the plastic connecting sleeve 20 with the connecting hole 11 on the profile 10, and press down on the plastic connecting sleeve 20 to insert the protrusion 22 into the connecting hole 11. The elastic card 12 is squeezed by the protrusion 22 and undergoes elastic deformation, then elastically returns to its original position and abuts against the protrusion 22, thereby completing the quick snap-fit ​​fixing of the wooden board 30 and the profile 10 without the need for additional tools or bolts, significantly improving installation efficiency. At the same time, the elastic abutment of the elastic card 12 can effectively prevent the protrusion 22 from loosening, ensuring the stability of the connection, and maintaining a good connection even after long-term use or under heavy load.

[0024] A number of spaced connecting holes 11 are punched at the upper end of the profile 10 using a punching machine. The connecting holes 11 have a D-shaped structure, and the punch of the punching machine adopts a corresponding D-shaped structure. After punching, the upper wall material of the profile 10 is not completely cut off, but some punching residue is bent and connected to the lower part of the connecting hole 11. This part of the punching residue is the elastic card 12. The elastic card 12 is suspended in the hollow interior of the profile 10 at an angle. During subsequent installation, after the protrusion 22 is inserted into the connecting hole 11, the elastic card 12 elastically abuts against the protrusion 22, thereby preventing the protrusion 22 from loosening. This punching design ensures the forming accuracy of the connecting hole 11 and provides a reliable elastic abutment structure through the elastic card 12 formed by the residual material. Compared with the traditional fully punched hole, the bending suspension structure of the elastic card 12 is not easy to break and can continuously provide uniform elastic pressure after the protrusion 22 is inserted, further improving the anti-loosening performance of the connection. At the same time, the cooperation between the D-shaped punch and the connecting hole 11 also facilitates the precise alignment of the protrusion 22 and reduces the installation difficulty.

[0025] Please refer to Figure 7The protrusion 22 includes a columnar connecting part 221 connected to the bottom surface of the plastic connecting sleeve 20 and a tapered insertion part 222 connected to the lower end of the columnar connecting part 221. The surface of the columnar connecting part 221 is provided with a plurality of annular flanges 223. The maximum outer diameter of the tapered insertion part 222 is larger than the outer diameter of the columnar connecting part 221, so that an annular groove is formed on the outer side of the columnar connecting part 221 to lock the lower wall surface and the inner wall surface of the connecting hole 11. When the protrusion 22 is inserted into the connecting hole 11, the tapered insertion part 222 first engages with the upper part of the connecting hole 11, and its tapered shape guides the protrusion 22 smoothly into the connecting hole 11. Then, the columnar connecting part 221 enters the connecting hole 11. The annular flange 223 and the annular groove work together to stably lock the lower part of the protrusion 22 onto the lower wall of the connecting hole 11, while the side is abutted by the elastic card 12, forming a stable limiting structure. This further prevents the plastic connecting sleeve 20 from shifting in the vertical and horizontal directions, and improves the reliability of the connection.

[0026] Please refer to Figure 6 The top surface of the plastic connecting sleeve 20 is provided with several reinforcing ribs 23. The reinforcing ribs 23 are arranged in a transverse direction, and each reinforcing rib 23 extends in a longitudinal direction. The extension direction of the reinforcing ribs 23 is consistent with the opening direction of the socket 21. When the wooden board 30 is inserted into the socket 21, the reinforcing ribs 23 can play a reinforcing role. The setting of the reinforcing ribs 23 enhances the overall structural strength of the plastic connecting sleeve 20. In particular, after the wooden board 30 is inserted, the reinforcing ribs 23 can disperse the pressure of the wooden board 30 on the socket 21, preventing the socket 21 from deforming or cracking due to excessive force.

[0027] Please refer to Figure 6 The top surface of the socket 21 is concave, and the bottom surface is concave. This inward-curving socket 21 structure allows the top and bottom surfaces of the socket 21 to exert an inward clamping force on the wooden board 30 after it is inserted. The wooden board 30 is firmly confined within the socket 21, preventing it from wobbling or coming out. At the same time, the inward-curving structure also increases the contact area between the wooden board 30 and the socket 21, further improving the stability of the connection. Even if the bed frame is subjected to external impact or long-term vibration, the wooden board 30 can maintain good positional stability.

[0028] Please refer to Figure 7The plastic connecting sleeve 20 has two protrusions 22, and the elastic clips 12 corresponding to the two protrusions 22 on the same plastic connecting sleeve 20 have opposite elastic force directions. The two protrusions 22 correspond to the two connecting holes 11 on the profile 10, and the design of opposite elastic force directions allows the two elastic clips 12 to apply elastic abutment force to the protrusions 22 from different directions after the plastic connecting sleeve 20 is installed, forming a symmetrical anti-loosening structure, effectively preventing the plastic connecting sleeve 20 from rotating or shifting in the horizontal direction, and further improving the stability and torsional performance of the connection; at the same time, the double protrusion 22 design also enhances the overall load-bearing capacity of the plastic connecting sleeve 20, and can better support the wooden board 30 and the load above it.

[0029] Please refer to Figure 1 This embodiment also discloses a bed frame, including a bed frame 40 and the aforementioned bed board connecting structure. Profiles 10 are connected to the bed frame 40, and wooden boards 30 are spaced apart on the inner side of the bed frame 40. After applying the bed board connecting structure to the bed frame, the wooden boards 30 are spaced apart on the inner side of the bed frame 40, forming a slatted frame structure. This ensures the breathability of the bed board and evenly distributes the weight of the human body, improving sleep comfort. At the same time, the quick-connect design of the bed board connecting structure makes the bed frame assembly simpler, reducing production assembly time and labor costs, and improving production efficiency.

[0030] Please refer to Figure 1 The bed frame 40 includes two crossbeams 41, two longitudinal beams 42, and right-angle connecting seats 43 for connecting the crossbeams 41 and longitudinal beams 42. A middle beam 44 connects the two longitudinal beams 42. Profiles 10 are fixed on both the crossbeams 41 and the middle beam 44. The crossbeams 41, longitudinal beams 42, and middle beam 44 together form the support frame of the bed frame 40. The right-angle connecting seats 43 ensure the vertical connection between the crossbeams 41 and longitudinal beams 42, improving the overall structural strength of the bed frame 40. The profiles 10 fixed on the crossbeams 41 and the middle beam 44 provide a mounting carrier for the wooden boards 30. The setting of the middle beam 44 further enhances the support capacity of the middle part of the bed frame 40, prevents the middle part of the bed board from collapsing, and improves the load-bearing performance and stability of the bed frame. The overall slatted frame structure consists of two rows of wooden boards 30, with each row of wooden boards 30 arranged at intervals to form a rib-like distribution, which not only ensures the uniformity of support but also has a good elastic cushioning effect.

[0031] Furthermore, the crossbeam 41 and the profile 10 are integrally formed, as are the intermediate beam 44 and the profile 10. This integral forming design avoids gaps between the crossbeam 41 and the profile 10, and between the intermediate beam 44 and the profile 10, improving the overall integrity and aesthetics of the structure. It also reduces the number of parts and simplifies the manufacturing process. The integrally formed connection parts are stronger and less prone to loosening or breakage under stress, further improving the stability and service life of the bed frame.

[0032] For further details, please refer to... Figure 8The intermediate beam 44 has sliding plates 45 and self-tapping screws at both ends. The self-tapping screws pass through the sliding plates 45 and are threadedly connected to the longitudinal beam 42. The sliding plates 45 can slide along the length of the intermediate beam 44. When the bed frame needs to be adapted to wooden boards 30 of different lengths or layouts, the relative distance between the intermediate beam 44 and the longitudinal beam 42 can be changed by adjusting the position of the sliding plates 45, and then locked and fixed with self-tapping screws to achieve flexible adjustment of the bed frame. This design not only improves the adaptability of the bed frame, but also adapts to different production or usage needs. In addition, in other embodiments, bolt fixing, slot and block fixing, etc. can also be used to replace self-tapping screws, further expanding the flexibility and applicability of the structure.

[0033] For further details, please refer to... Figure 9 The bed frame 40 has support components 50 at its four corners. Each support component 50 includes a first mounting base 51 fixed to the bottom of the crossbeam 41, a second mounting base 52 fixed to the bottom of the longitudinal beam 42, a diagonal support beam 53 connecting the first mounting base 51 and the second mounting base 52, and support feet 55 bolted to the lower end of the diagonal support beam 53. The support components 50 transfer the weight of the bed frame 40 to the support feet 55, improving the overall support height and stability of the bed frame. The combination of the first mounting base 51, the second mounting base 52, and the diagonal support beam 53 forms a triangular support structure, which enhances the load-bearing capacity of the bed frame 40 by utilizing the stability of the triangle, preventing the bed frame 40 from tilting or deforming. The bolted connection method facilitates installation and adjustment, and the height of the support feet 55 can be finely adjusted according to the actual use environment to ensure that the bed frame is placed stably.

[0034] Example 2 Please refer to Figure 10-12As shown, the main difference between this embodiment and embodiment 1 is that the plastic connecting sleeve 20 located at the middle beam 44 position has two opposite insertion ports 21, and the two insertion ports 21 are respectively inserted into two wooden boards 30. The protrusion 22 is located between the two insertion ports 21. Moreover, the profile 10 at the middle beam 44 position uses only one profile 10 and has a row of horizontal connecting holes 11. During installation, one end of each of the two wooden boards 30 is inserted into the two opposing slots 21 of the plastic connecting sleeve 20 at the position of the middle beam 44. The protrusions 22 of the plastic connecting sleeve 20 are aligned with the connecting holes 11 on the profile 10 and pressed down, so that the protrusions 22 are engaged and fixed with the elastic clips 12. This design of the double-opening plastic connecting sleeve 20 allows the profile 10 at the position of the middle beam 44 to fix the two wooden boards 30 at the same time with only one row of connecting holes 11, reducing the number of punches on the profile 10 and the processing cost, and simplifying the production process of the profile 10. At the same time, the two wooden boards 30 are connected by the same plastic connecting sleeve 20, which ensures the relative positional stability between the two wooden boards 30, avoids the spacing deviation caused by separate fixing, and improves the overall flatness and support consistency of the frame. In addition, this structure can flexibly adjust the arrangement and number of wooden boards 30 as needed, expanding the design diversity of the bed frame.

[0035] The above-described embodiments are merely illustrative of several specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
