[0004] The splicing rods and other components in the aforementioned patents are made of metal. These splicing rods generate significant noise during installation, affecting the user experience when installing the bed frame. Utility Model Content

[0005] To reduce noise during bed frame installation, this application provides a low-noise bed frame.

[0006] The low-noise bed frame provided in this application adopts the following technical solution:

[0007] A low-noise bed frame, comprising:

[0008] The main frame is rectangular and includes two horizontal fixing rods and two vertical fixing rods, with the ends of the horizontal fixing rods perpendicularly connected to the ends of the vertical fixing rods.

[0009] Several support columns are fixed to the frame body to provide support for the frame body.

[0010] A longitudinal support rod is located between two longitudinal fixed rods and is parallel to the longitudinal fixed rods. The end of the longitudinal support rod is fixed to the support column.

[0011] Several transverse support rods are located between the transverse fixed rod and the longitudinal fixed rod, and are parallel to the transverse fixed rod. The outer end of the transverse support rod is engaged with the longitudinal fixed rod, and an elastic element is provided at the engagement point. The inner end of the transverse support rod is engaged with the longitudinal support rod, and an elastic element is provided at the engagement point.

[0012] By adopting the above technical solution, during installation, the outer end of the transverse support rod is snapped into the longitudinal fixing rod, and the inner end of the transverse support rod is snapped into the longitudinal support rod. Since elastic element one and elastic element two are designed at the snapping point, elastic element one and elastic element two can play a role in buffering and shock absorption when the transverse support rod is installed, thereby reducing noise and improving the experience of installing the bed frame.

[0013] Preferably, the elastic element has a mounting groove, and the outer end of the transverse support rod is inserted into the mounting groove of the elastic element; the longitudinal fixing rod has an inner cavity, and the inner side of the longitudinal fixing rod has a snap-fit ​​hole communicating with the inner cavity, and the snap-fit ​​part of the elastic element passes through the snap-fit ​​hole and is inserted into the inner cavity.

[0014] By adopting the above technical solution, the elastic element is set on the outer end of the transverse support rod, and the snap-fit ​​part of the elastic element is inserted into the inner cavity of the longitudinal fixing rod, so as to realize the snap-fit ​​between the transverse support rod and the longitudinal fixing rod, while avoiding direct contact between the transverse support rod and the longitudinal fixing rod, thus reducing the noise generated during the installation of the transverse support rod.

[0015] Preferably, the elastic element further includes a limiting flange connected to the snap-fit ​​portion, the snap-fit ​​portion being inserted into the inner cavity of the longitudinal fixing rod, and the limiting flange being located outside the inner cavity of the longitudinal fixing rod and able to abut against the side wall of the longitudinal fixing rod.

[0016] By adopting the above technical solution and setting a limit flange, it is possible to prevent the elastic element from falling into the inner cavity of the longitudinal fixing rod due to friction during disassembly.

[0017] Preferably, the snap-fit ​​portion of the elastic element has a barb, which can be deformed to pass through the snap-fit ​​hole and snap into the inner cavity of the longitudinal fixing rod. The distance between the end of the barb near the limiting flange and the end of the limiting flange near the barb is greater than or equal to the thickness of the inner wall of the longitudinal fixing rod.

[0018] By adopting the above technical solution, the barb is deformed and engaged in the inner cavity of the longitudinal fixing rod, cooperating with the limiting flange to avoid a large gap between the elastic element and the longitudinal fixing rod, thereby improving the stability of the connection between the transverse support rod and the longitudinal fixing rod.

[0019] Preferably, a connecting bracket is fixed to the upper end face of the longitudinal support rod. The connecting bracket has a U-shaped groove with the opening facing upward. Both ends of the U-shaped groove pass through the connecting bracket. The second elastic element is disposed in the U-shaped groove and has a snap-fit ​​groove. The inner end of the transverse support rod is snapped into the snap-fit ​​groove.

[0020] By adopting the above technical solution, the inner end of the transverse support rod is engaged with the snap-fit ​​groove, and does not directly contact the longitudinal support rod. The elastic element 2 plays a buffering role, reducing noise during installation.

[0021] Preferably, the side wall of the connecting bracket is provided with a connecting hole communicating with the U-shaped groove, and the outer side of the elastic element two has barbs two, which can be engaged in the connecting hole through elastic deformation.

[0022] By adopting the above technical solution, the second elastic element is snapped into the connecting bracket by the second barb, making replacement and maintenance quick.

[0023] Preferably, the snap-fit ​​groove of the second elastic element is provided with a limiting protrusion, and the inner end of the transverse support rod can be in contact with the limiting protrusion.

[0024] By adopting the above technical solution, the elastic element 2 is equipped with a limiting protrusion, which can reduce the risk of the lateral support rod moving sideways.

[0025] Preferably, the first elastic element and the second elastic element are plastic or rubber parts.

[0026] By adopting the above technical solution, the elastic component and the elastic component are designed as plastic or rubber parts, which can generate elastic deformation to provide cushioning while keeping material costs low.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Two elastic elements are provided at the snap-fit ​​joint. When the horizontal support rod is installed, elastic elements one and two can play a role in buffering and shock absorption, thereby reducing noise and improving the experience of installing the bed frame.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, the bed frame includes a main frame 1, support columns 2, longitudinal support rods 3, and transverse support rods 4.

[0038] In this embodiment, the frame body 1 is rectangular and includes two horizontal fixing rods 11 and two vertical fixing rods 12. The ends of the horizontal fixing rods 11 and the ends of the vertical fixing rods 12 are perpendicularly connected. The connection can be achieved by fasteners such as screws for detachable connection, or by rivets, welding or other methods for non-detachable connection.

[0039] There are several support columns 2, which are fixed to the frame body 1 to provide support for the frame body 1.

[0040] Preferably, the connection between the transverse fixing rod 11 and the longitudinal fixing rod 12 is provided with a support column 2, the midpoint of the transverse fixing rod 11 and the longitudinal fixing rod 12 is also provided with a support column 2, and the midpoint of the longitudinal support rod 3 is also provided with a support column 2.

[0041] The longitudinal support rod 3 is located between the two longitudinal fixed rods 12 and is parallel to the longitudinal fixed rods 12. The end of the longitudinal support rod 3 is fixed to the support column 2. The connection method can be screws, connectors or a combination of screws and connectors.

[0042] In this embodiment, the end of the longitudinal support rod 3 is located at the midpoint of the transverse fixing rod 11, and the transverse support rod 4 is located between the transverse fixing rod 11 and the longitudinal support rod 3, and is parallel to the transverse fixing rod 11. That is, transverse support rods 4 are distributed on both sides of the longitudinal support rod 3.

[0043] like Figure 1 , Figure 3 , Figure 4 As shown, the outer end of the transverse support rod 4 is engaged with the longitudinal fixing rod 12, and an elastic element 5 is provided at the engagement point.

[0044] Specifically, the elastic element 5 is sleeve-shaped and has an installation groove 51. The outer end of the transverse support rod 4 is inserted into the installation groove 51 of the elastic element 5. The longitudinal fixing rod 12 has an inner cavity 121. The inner side of the longitudinal fixing rod 12 has a snap-fit ​​hole communicating with the inner cavity 121. The snap-fit ​​part 52 of the elastic element 5 passes through the snap-fit ​​hole and is inserted into the inner cavity 121.

[0045] In this embodiment, the elastic element 5 also includes a limiting flange 53 connected to the snap-fit ​​portion 52. The snap-fit ​​portion 52 is inserted into the inner cavity 121 of the longitudinal fixing rod 12. The limiting flange 53 is located outside the inner cavity 121 of the longitudinal fixing rod 12 and can be attached to the side wall of the longitudinal fixing rod 12, so as to prevent the elastic element 5 from falling into the inner cavity 121 of the longitudinal fixing rod 12 due to friction during disassembly.

[0046] The snap-fit ​​portion 52 of the elastic element 5 has a barb 54. The barb 54 can deform through the snap-fit ​​hole and snap into the inner cavity 121 of the longitudinal fixing rod 12. The distance between the end of the barb 54 near the limiting flange 53 and the end of the limiting flange 53 near the barb 54 is greater than or equal to the thickness of the inner wall of the longitudinal fixing rod 12. The barb 54 snaps into the inner cavity 121 of the longitudinal fixing rod 12 through deformation, and cooperates with the limiting flange 53 to avoid a large gap between the elastic element 5 and the longitudinal fixing rod 12, thereby improving the stability of the connection between the transverse support rod 4 and the longitudinal fixing rod 12.

[0047] In this embodiment, the elastic element 5 is a plastic or rubber part, and the snap-fit ​​part 52, the limiting flange 53, and the barb 54 adopt an integrally formed structure. When the barb 54 passes through the snap-fit ​​hole, the deformation can be that both the snap-fit ​​part 52 and the barb 54 deform.

[0048] As an alternative, the barb 54, the limiting flange 53, and the snap-fit ​​part 52 can also be designed as separate structures. The deformation of the barb 54 when passing through the snap-fit ​​hole can also be the deformation of only the barb 54 itself.

[0049] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the inner end of the transverse support rod 4 is engaged with the longitudinal support rod 3, and an elastic element 6 is provided at the engagement point.

[0050] In this embodiment, a connecting bracket 7 is fixed to the upper end face of the longitudinal support rod 3. The connecting bracket 7 has a U-shaped groove 71 with the opening facing upward and both ends of the U-shaped groove 71 penetrating through the connecting bracket 7.

[0051] Preferably, the connecting bracket 7 is U-shaped; as another option, the connecting bracket 7 can be of other shapes, as long as it has a corresponding U-shaped groove 71.

[0052] The second elastic element 6 is disposed in the U-shaped groove 71, and the second elastic element 6 has a snap-fit ​​groove 61, and the inner end of the transverse support rod 4 is snapped into the snap-fit ​​groove 61.

[0053] In this embodiment, the elastic element 6 is also U-shaped, and its shape is in contact with the U-shaped groove 71.

[0054] The side wall of the connecting bracket 7 has a connecting hole 72 that communicates with the U-shaped groove 71. The outer side of the elastic element 6 has a barb 62, which can be engaged in the connecting hole 72 through elastic deformation.

[0055] Preferably, the locking groove 61 of the elastic element 2 6 is provided with a limiting protrusion 63, and the inner end of the transverse support rod 4 can be in contact with the limiting protrusion 63.

[0056] Since there are transverse support rods 4 on both sides of the longitudinal support rod 3, the ends of the transverse support rods 4 on both sides can directly contact the limiting protrusions 63 during installation, causing the limiting protrusions 63 to deform, improving connection stability while reducing the risk of the transverse support rods 4 moving around.

[0057] In this embodiment, the elastic element 2 6 is also a plastic or rubber part, and the limiting protrusion 63 and the elastic element 2 6 are an integral structure. As another option, it can also be designed as a separate part.

[0058] The working principle of this embodiment is as follows: During installation, the outer end of the transverse support rod 4 is snapped with the longitudinal fixing rod 12, and the inner end of the transverse support rod 4 is snapped with the longitudinal support rod 3. Since the design provides elastic element 1 5 and elastic element 2 6 at the snapping point, the elastic element 1 5 and elastic element 2 6 can play a buffering and shock-absorbing role when the transverse support rod 4 is installed, thereby reducing noise and improving the experience of installing the bed frame.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
