Abstract
Description
Technical Field
[0001] This utility model relates to the field of folding bed technology, and in particular to a folding bed frame and bed with automatic joints. Background Technology
[0002] Foldable bed frames are favored for their foldable feature. When needed, the bed frame can be unfolded for resting, and when not in use, it can be folded up for storage, reducing space usage and making it very convenient.
[0003] Currently, traditional folding bed frames on the market typically use hinges, riveting, or bolts to connect the bed legs to the bed frame. The hinges allow for relative movement and folding between the bed frame and the bed legs. However, conventional hinges are not fixed in place. If the folding bed shifts significantly during use, the hinges may rotate, causing the bed legs to fold up and the bed frame to collapse, posing a significant safety hazard.
[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] To address the technical problem of the inability to relatively fix the legs of traditional folding beds, this utility model provides a folding bed frame with automatic joints. The folding bed frame with automatic joints includes a first bed frame and at least two sets of folding legs. The two sets of folding legs are respectively disposed at both ends of the first bed frame and are movably connected to the first bed frame. Each folding leg includes a first bed leg and an automatic joint. The first bed leg is movably connected to the first bed frame, and both ends of the automatic joint are movably connected to the first bed frame and the first bed leg, respectively.
[0006] The automatic joint includes a first link, a second link, and a limiting part. The first link is movably connected to the first bed leg, and the first link is sleeved on the second link. The first link and the second link are movably connected, and the second link is movably connected to the first bed frame. The first link has an adjustment groove, and the second link has a positioning groove. The limiting part is movably connected to the adjustment groove and the positioning groove, respectively.
[0007] Furthermore, the limiting part includes an adjusting member and a positioning pin. The adjusting member is movably connected to the first connecting rod, and the positioning pin is disposed on the adjusting member. The positioning pin passes through the adjusting groove and is movably connected to the adjusting groove and the positioning groove, respectively.
[0008] Furthermore, the automatic joint also includes an elastic element, the two ends of which are respectively connected to the first connecting rod and the adjusting element.
[0009] Furthermore, the automatic joint also includes a guide member, which is fixed to the first connecting rod and is movably connected to the adjusting member.
[0010] Furthermore, the second link includes two of the aforementioned positioning slots.
[0011] Furthermore, each set of the folding bed legs includes two of the aforementioned automatic joints.
[0012] Furthermore, the first bed frame includes a movable first bed body and a second bed body, with the first bed body and the second bed body being movably connected.
[0013] Furthermore, the first bed frame also includes a second bed leg, which is movably connected to the first bed body and the second bed body, respectively.
[0014] Furthermore, the folding bed frame with automatic joints also includes a plurality of spokes, which are arranged at intervals on the first bed body and the second bed body.
[0015] Furthermore, this utility model also provides a bed comprising a folding bed frame with automatic joints as described in any one of the above claims.
[0016] Based on the above, the folding bed frame and bed with automatic joints provided by this utility model, compared with the prior art, uses automatic joints instead of traditional hinges, and the fixed and movable states of the automatic joints can be changed by positioning pins.

[0028] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of a folding bed frame with automatic joints provided in an embodiment of the present invention; Figure 2 An exploded view of a folding bed frame with automatic joints, provided as an embodiment of the present invention.
[0029] To address the technical problem of the inability to relatively fix the legs of traditional folding beds, or to achieve at least one or more of the aforementioned advantages, an embodiment of this utility model provides a folding bed frame with automatic joints. As shown in the figure, the folding bed frame with automatic joints includes a first bed frame 100 and at least two sets of folding bed legs 200.
[0030] The first bed frame 100 includes a first bed body 110 and a second bed body 120. In practice, the first bed body 110 and the second bed body 120 are movably connected, allowing them to be folded, thus reducing the space occupied by the first bed frame 100 when folded. Preferably, the first bed frame 100 can be made of metal, which is lighter and has better strength.
[0031] Preferably, the first bed frame 100 further includes a second bed leg 130. The first bed body 110 and the second bed body 120 form a foldable movable connection structure through the second bed leg 130. At the same time, the second bed leg 130 can provide support for the first bed frame 100 in the unfolded state, making the first bed frame 100 more stable and smooth.
[0032] Two sets of folding bed legs 200 are respectively located at both ends of the first bed frame 100 and are movably connected to the first bed frame 100. Specifically, one set of folding bed legs 200 is movably located on one side of the first bed frame 110, providing support for the first bed frame 110. The other set of folding bed legs 200 is movably located on the side of the second bed frame 120 away from the first bed frame 110. When the user needs to use the bed, the first bed frame 110 and the second bed frame 120 can be unfolded, and then the two sets of folding bed legs 200 can be unfolded to form a complete bed frame for use.
[0033] like Figure 3 As shown, the folding bed leg 200 includes a first bed leg 210 and an automatic joint 220. In specific implementation, the first bed leg 210 is movably connected to the first bed frame 100. The two ends of the automatic joint 220 are movably connected to the first bed frame 100 and the first bed leg 210, respectively, that is, the first bed frame 100, the first bed leg 210, and the automatic joint 220 can form a stable triangle, providing stable support and improving stability.
[0034] like Figure 4 then Figure 5 As shown, to provide stable support by forming a stable triangle between the first bed frame 100, the first bed leg 210, and the automatic joint 220, and to enable the folding bed leg 200 to have a foldable characteristic, the automatic joint 220 includes a first link 221 and a second link 222. Specifically, the first link 221 is movably connected to the first bed leg 210. The first link 221 is fitted onto the second link 222, forming a slidable connection between them. The second link 222 is movably connected to the first bed frame 100. When the relative position between the first link 221 and the second link 222 is adjusted, the length of the automatic joint 220 changes, resulting in a foldable structural relationship between the folding bed leg 200 and the first bed frame 100.
[0035] Furthermore, the automatic joint 220 also includes a limiting part 223. Specifically, the first link 221 has an adjustment groove 300. The second link 222 has a positioning groove 400. The limiting part 223 can pass through the adjustment groove 300 and engage with the positioning groove 400. When the limiting part 223 engages with the positioning groove 400, the first link 221 and the second link 222 cannot slide, so that the length of the automatic joint 220 is relatively fixed, forming a stable triangle with the first bed frame 100 and the first bed leg 210, avoiding safety hazards caused by the rotation and folding of the folding bed leg 200 when the first bed frame 100 may shift.
[0036] In some preferred embodiments, the limiting part 223 includes an adjusting member 2231 and a positioning pin 2232. The adjusting member 2231 is movably connected to the first connecting rod 221. Specifically, the adjusting member 2231 and the first connecting rod 221 are perpendicular to each other and form a sliding connection. The positioning pin 2232 is disposed on the adjusting member 2231, and the positioning pin 2232 can pass through the adjusting groove 300 and engage with the positioning groove 400. By adjusting the adjusting member 2231, the positioning pin 2232 can be controlled to engage or disengage with the positioning groove 400, allowing the user to freely control the folding and unfolding of the folding bed leg 200.
[0037] Preferably, there can be two positioning slots 400 on each second link 222, so that the automatic joint 220 can be fixed in both unfolded and folded states, avoiding the problem that the folding bed legs cannot be fixed and unfolded after folding.
[0038] Based on the above, the automatic joint 220 also includes an elastic element 224. The two ends of the elastic element 224 are respectively connected to the first connecting rod 221 and the adjusting element 2231. In a specific implementation, the elastic element 224 can be a spring. The two ends of the elastic element 224 abut against the first connecting rod 221 and the adjusting element 2231 respectively, so that the positioning pin 2232 can be stably engaged with the positioning groove 400 without falling off, while also facilitating user operation of the adjusting element 2231.
[0039] In some preferred embodiments, the automatic joint 220 further includes a guide 225. The guide 225 is fixed to the first link 221. Specifically, the guide 225 is fixed to one side of the first link 221 and forms a sliding connection with the adjusting member 2231. When the user adjusts the adjusting member 2231, the guide 225 can provide guidance for the adjusting member 2231, preventing the elastic member 224 from getting stuck or disengaging due to the left and right swinging of the adjusting member 2231.
[0040] In some preferred embodiments, each set of folding bed legs 200 includes two automatic joints 220, enabling the folding bed legs 200 to fold or unfold smoothly.
[0041] In some preferred embodiments, the folding bed frame with automatic joints also includes a plurality of spokes 500. The plurality of spokes 500 are arranged at intervals on the first bed body 110 and the second bed body 120.
[0042] In some preferred embodiments, connection holes 600 may be provided along the side edge of the first bed frame 100. Users can connect two or more first bed frames 100 via connectors 700 according to specific usage needs, thereby increasing the reach and improving the user experience.
[0043] In some preferred embodiments, the present invention also provides a bed comprising a folding bed frame with automatic joints, as described above.
[0044] In summary, the folding bed frame and bed with automatic joints provided by this utility model, compared with the prior art, uses automatic joints instead of traditional hinges, and the fixed and movable states of the automatic joints can be changed by positioning pins. This allows the folding bed legs to have foldable characteristics while being fixed in the unfolded or folded state, forming a stable connection relationship. This improves the support stability of the folding bed legs and avoids the safety hazards caused by the rotation or folding of the folding bed legs due to possible displacement of the first bed frame.
