Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly relates to a bed frame. Background Art

[0002] The existing bed frame for nursing includes a bottom frame, a backrest arranged at the edge of the bottom frame, and guardrails arranged on both sides of the bottom frame. The bottom frame is used to support a mattress or an electric slat frame, and the guardrails are used to limit the displacement of the user, preventing the user from turning over and falling, and also facilitating the user to grasp when getting up and lying down. The middle section of the side plate of the existing bottom frame is an independently arranged structure, and the bottom frame with a conventional wooden board structure has insufficient rigidity. After the guardrail is connected to the bottom frame, when the guardrail is laterally stressed, it is easy to drive the bottom frame to deform, affecting the stability of the bottom frame, shortening the service life of the bottom frame, and affecting the use experience. Summary of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a bed frame, which is provided with a connection component that clamps and fixedly connects the side plates through an internal component and an external component, and a reinforcing bar is arranged between the corresponding connection components on both side plates, ensuring that the guardrail can be firmly connected to the side plate through the connection component, providing effective limitation for the user by the guardrail, and also improving the anti-deformation performance of the side plate by arranging the reinforcing bar, prolonging the service life of the bottom frame, and improving the use experience.

[0004] The utility model is realized in the following way: A bed frame includes a bottom frame and guardrails arranged above both sides of the bottom frame. The bottom frame includes parallelly arranged side plates and end plates bridging between the corresponding ends of the side plates. The guardrails are fixedly connected to the side plates of the bottom frame through connection components. The connection components include internal components arranged on the inner walls of the side plates and external components arranged on the outer walls of the side plates and supporting the guardrails. The external components and the internal components are clamped and fixedly connected to the side plates through fasteners, and at least one reinforcing bar is arranged between the connection components on both side plates. By arranging the connection components that clamp and fixedly connect the side plates through the internal components and the external components, it is ensured that the guardrail can be firmly connected to the side plate through the connection component, providing effective limitation for the user by the guardrail, preventing the user from falling, ensuring the safety of the user, and arranging the reinforcing bar between the corresponding connection components on both side plates. The reinforcing bar can transmit the acting force between the two side plates, effectively improving the anti-deformation performance of the side plate, and further prolonging the service life of the bottom frame and improving the use experience.

[0005] Preferably, corresponding through holes are provided on the external components, the side plates, and the internal components, and the fasteners pass through the through holes and are screwed and locked with nuts so that the external components and the internal components move closer to each other and clamp the side plates. The external components and the internal components are respectively attached to the two side walls of the side plate and fixedly connected and locked through the fasteners passing through the through holes, ensuring that the connection component is fixedly connected to the side plate and maintaining the relative position fixed, providing effective support and positioning for the guardrail.

[0006] Preferably, there are at least two fasteners which are vertically arranged separately, so that the external part and the side plate, and the side plate and the internal part are closely attached. By increasing the number of fasteners, the connection strength between the connection component and the side plate is improved, effectively preventing the connection component from shifting or deflecting relative to the side plate. Furthermore, it ensures that the guardrail is firmly installed on the side plate in a vertical posture, playing a role in limiting and providing a grasping support for the user.

[0007] Preferably, the connection component includes a U-shaped connecting piece integrally arranged. The two end parts of the connecting piece respectively form the external part and the internal part, and the inner cavity width of the connecting piece matches the thickness of the side plate. The integrally formed connecting piece is convenient for assembly, without the need to adjust the relative positions between the external part and the internal part, improving the assembly efficiency.

[0008] Preferably, the external part includes a vertical plate that fits against the outer wall of the side plate and a horizontal plate arranged in the middle of the outer side of the vertical plate. The connection component includes a bottom bar arranged on the horizontal plate for the guardrail to be stacked and connected. The bottom bar is fixedly connected by at least one fastener passing through it. The vertical plate fits against the outer wall of the side plate, improving the positioning reliability by increasing the contact area to ensure a firm connection between the external part and the side plate. The relative position between the horizontal plate and the side plate is fixed, ensuring that the horizontal plate can obtain the support of the vertical plate and effectively support the bottom bar, ensuring the reliable installation of the guardrail. The bottom bar is fixedly connected by at least one fastener passing through it, ensuring the relative position between the bottom bar and the side plate is fixed, and thus ensuring a firm connection between the guardrail and the side plate.

[0009] Preferably, a reinforcing rib is provided between the bottom of the horizontal plate and the vertical plate. By providing the reinforcing rib, the connection reliability between the vertical plate and the horizontal plate is improved. Furthermore, it ensures that the force received by the guardrail can be transmitted from the horizontal plate to the vertical plate and finally to the side plate, ensuring that the guardrail can effectively resist external forces and provide a reliable limiting effect.

[0010] Preferably, the guardrail includes a number of vertical rods arranged separately along the length direction of the side plate and a longitudinal rod spanning between the tops of the vertical rods. The vertical rods are swingably installed on the corresponding bottom bars through rotating shafts, so that the vertical rods can swing synchronously back and forth to drive the guardrail to switch between the use state and the storage state. The bottom of the vertical rod is swingably connected to the bottom bar, and the top is swingably connected to the longitudinal rod, enabling the longitudinal rod to swing around the bottom of the vertical rod and guiding the guardrail to switch between the raised use state and the lowered storage state. When the guardrail is in the use state, the longitudinal rod is suspended above the bottom bar. When the guardrail is in the storage state, the longitudinal rod descends and approaches the bottom bar, facilitating the user to get on or off the bed.

[0011] Preferably, the reinforcing bar is arranged between the corresponding internal parts on the side plate to limit the deflection and offset of the side plate under stress. The internal parts are arranged on the opposite inner walls of the two side plates. The reinforcing bar spans between the corresponding internal parts, playing a role in supporting and positioning the side plate, and thus effectively improving the anti-deformation performance of the side plate.

[0012] Preferably, connecting plates that are fitted and fixedly connected to the inner walls of the corresponding side plates are provided at both ends of the transverse reinforcing rod, and the connecting plates form the built-in components. Connecting plates are fixedly connected to both ends of the reinforcing rod. The connecting plates are in contact with the inner walls of the side plates and form built-in components that cooperate with the external components to clamp the side plates, which not only effectively simplifies the structure but also ensures that the reinforcing rod can be fixedly connected to the side plate through the connecting plate, and then fixedly connected to the guardrail through the external component, improving the anti-deformation performance of the side plate.

[0013] Preferably, a clamping cavity is provided inside the side plate. The side plate includes an outer clamping plate, an inner clamping plate, and a sandwich wooden strip. The top and bottom edges of the outer clamping plate and the inner clamping plate are connected by the sandwich wooden strip to enclose and form the clamping cavity. The outer clamping plate and the inner clamping plate are arranged in parallel and fixedly connected by the sandwich wooden strip, which not only ensures that the side plate has a firm outer wall and inner wall, facilitating the clamping and fixing of the connecting components, but also reduces the raw material usage and cost by setting the clamping cavity.

[0014] The beneficial effects of the present utility model are as follows: A connecting component for clamping and fixedly connecting the side plate through the built-in component and the external component is provided to ensure that the guardrail can be firmly connected to the side plate through the connecting component, providing effective limit for the user, preventing the user from falling, ensuring the safety of the user. A reinforcing rod is provided between the corresponding connecting components on both side plates. The reinforcing rod can transmit the acting force between the two side plates, effectively improving the anti-deformation performance of the side plate, thereby extending the service life of the bottom frame and enhancing the use experience.

The external parts 5 and the built-in parts 6 are clamped and fixedly connected to the side plates 3 through fasteners 7. At least one reinforcing rod 12 is arranged between the connecting components on the two side plates 3. The connecting components that clamp and fixedly connect the side plates 3 through the built-in parts 6 and the external parts 5 ensure that the guardrails 2 can be firmly connected to the side plates 3 through the connecting components, ensure that the guardrails 2 provide effective limiting for users, prevent users from falling, ensure the safety of users. The reinforcing rod 12 is arranged between the corresponding connecting components on the two side plates 3. The reinforcing rod 12 can transmit the acting force between the two side plates 3, effectively improving the anti-deformation performance of the side plates 3, and further extending the service life of the bottom frame 1 and improving the use experience.

[0021] In actual operation, the guardrails 2 are fixedly connected to the side plates 3 through at least two groups of separately arranged connecting components, ensuring that the guardrails 2 can maintain a vertical posture, and further effectively preventing the guardrails 2 from tilting and toppling, ensuring the use safety.

[0022] In actual operation, the connecting components include built-in parts 6 and external parts 5. Corresponding through holes are provided on the external parts 5, the side plates 3, and the built-in parts 6. The external parts 5 include vertical plates 19 attached to the outer walls of the side plates 3 and transverse plates 18 arranged in the middle of the outer sides of the vertical plates 19. The connecting components include bottom bars 8 arranged on the transverse plates 18 for the guardrails 2 to be stacked and connected. During installation, the built-in parts 6 and the external parts 5 are respectively attached to the inner and outer walls of the side plates 3 and are screwed and locked with nuts through fasteners 7 passing through the through holes, so that the external parts 5 and the built-in parts 6 move closer to each other and clamp the side plates 3. The guardrails 2 are installed on the bottom bars 8 and can be switched between a storage state and a use state.

[0023] In actual operation, there are at least two fasteners 7 and they are arranged vertically and separately, so that the external parts 5 and the side plates 3, and the side plates 3 and the built-in parts 6 are closely attached. The bottom bars 8 are penetrated and fixedly connected by at least one fastener 7, ensuring a firm connection between the bottom bars 8 and the side plates 3, and further providing effective support for the guardrails 2.

[0024] In actual operation, a reinforcing rib 9 is arranged between the bottom of the transverse plate 18 and the vertical plate 19. The reinforcing rib 9 is in a right triangle shape, and the edges of the reinforcing rib 9 are respectively attached and fixedly connected to the transverse plate 18 and the vertical plate 19, ensuring that the transverse plate 18 and the vertical plate 19 stably maintain a vertically arranged posture.

[0025] In actual operation, the connection component can have various structures and can be used in combination to ensure the firm connection between the guardrail 2 and the side plate 3. The connection component includes but is not limited to the following structures:

[0026] Structure 1: The connection component includes a U-shaped connecting piece integrally provided. The two end parts of the connecting piece respectively form the external part 5 and the internal part 6. The inner cavity width of the connecting piece matches the thickness of the side plate 3. During installation, the connecting piece is sleeved on the top edge of the side plate 3, so that after the internal part 6 and the external part 5 clamp the side plate 3, they are fixedly connected by a fastener 7.

[0027] Structure 2: The connection component includes a separately provided internal part 6 and external part 5. The internal part 6 and the external part 5 are respectively attached to the inner wall and the outer wall of the side plate 3 and are fixedly connected by a fastener 7.

[0028] Structure 3: As Figure 2 shown, the connection component includes a separately provided internal part 6 and external part 5. The two end parts of the transverse reinforcing bar 12 are provided with connecting plates 13 that are fixedly attached to the inner wall of the corresponding side plate 3. The connecting plates 13 form the internal part 6. The internal part 6 and the external part 5 are respectively attached to the inner wall and the outer wall of the side plate 3, and a reinforcing bar 12 is provided between the internal parts 6 on both side plates 3. The connection component not only plays a role in clamping the side plate 3, but also plays a role in improving the anti-deformation performance of the side plate 3, thereby effectively preventing the guardrail 2 from tilting horizontally due to the deformation of the side plate 3.

[0029] In actual operation, the guardrail 2 includes a plurality of vertical bars 10 distributed along the length direction of the side plate 3 and a longitudinal bar 11 straddling the tops of the vertical bars 10 (as Figure 3 shown). The vertical bars 10 are swingably installed on the corresponding bottom brackets 8 through rotating shafts, so that the vertical bars 10 can swing synchronously back and forth and drive the guardrail 2 to switch between the use state and the storage state. The longitudinal bar 11 is connected to the connection component through a plurality of vertical bars 10. The longitudinal bar 11 always maintains a horizontal posture and can swing around the bottom end of the vertical bar 10, so that the guardrail 2 can switch between the use state where the longitudinal bar 11 is lifted and the storage state where the longitudinal bar 11 falls, which is convenient for use.

[0030] In actual operation, a clamping cavity 17 is provided inside the side plate 3. The side plate 3 includes an outer clamping plate 14, an inner clamping plate 15, and a sandwich wood strip 16. The top and bottom edges of the outer clamping plate 14 and the inner clamping plate 15 are connected by the sandwich wood strip 16 to enclose and form the clamping cavity 17. The outer clamping plate 14 and the inner clamping plate 15 are arranged in parallel, and the sandwich wood strip 16 is provided between the corresponding regions of the two, ensuring that each region of the side plate 3 has good compressive performance and preventing the side plate 3 from being recessed due to local stress, which affects the clamping reliability between the built-in part 6 and the external part 5. The sandwich wood strips 16 are separately arranged and can form the clamping cavity 17 between the inner clamping plate 15 and the outer clamping plate 14, which not only ensures that the side plate 3 has good structural strength, but also effectively reduces the weight of the side plate 3, reduces the raw material consumption, and reduces the cost.
