DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0025] Example:

[0026] like Figure 1-5 As shown, this embodiment provides a desk-connected folding bed, comprising a bed frame 1 and a mattress 2, wherein two ends of the bed frame 1 are rotatably connected with a support member 3 and a rotating rod 4, respectively, the support member 3 is arranged in an inverted "T" shape, and the support member 3 has a vertically arranged support rod 6 and a horizontally arranged fixing rod 7 and a positioning rod 8;

[0027] The lower end surface of the middle part of the bed frame 1 is also rotatably connected to a desk 5, and the desk 5 has a connecting plate 9 and a desktop 10;

[0028] A connecting rod 11 is rotatably connected between the rotating rod 4 and the supporting rod 6 , and a connecting rod 12 is rotatably connected between the end of the positioning rod 8 and the middle of the desktop 10 .

[0029] In a specific application scenario, during the rotation of the bed frame 1 and the mattress 2 from the horizontal to the vertical state, the desk 5 connected to the middle of the lower end surface of the bed frame 1 will be synchronously lifted, and the middle of the desktop 10 is connected to the end of the positioning rod 8 through the connecting rod 12. Therefore, during the lifting of the desk 5 as a whole, it will be pulled and supported by the connecting rod 12, so that the desk 5 as a whole always remains in a horizontal state. After the bed frame 1 and the mattress 2 rotate to the vertical folding state, the desk 5 as a whole is unfolded from the bottom of the bed frame 1, so that the upper end surface of the desktop 10 provides a space for work and study, and the indoor activity space is increased by vertically folding the bed frame 1 and the mattress 2. The following is a further description of the desk-connected folding bed of the utility model in combination with this application scenario.

[0030] Further, refer to Figure 1-5 The bed frame 1 and the connecting rod 11 are arranged in parallel, the rotating rod 4 and the supporting rod 6 are arranged in parallel, and the length of the rotating rod 4 is consistent with the length of the supporting rod 6.

[0031] In this embodiment, when the bed frame 1 and the mattress 2 are subjected to force to rotate and lift, in order to make the rotating rod 4 and the connecting rod 11 rotate synchronously, the bed frame 1 and the connecting rod 11 are set to be parallel, and the rotating rod 4 and the supporting rod 6 are set to be parallel, so that the bed frame 1, the rotating rod 4, the supporting rod 6, and the connecting rod 11 move synchronously with the lifting of the bed frame 1 in a parallelogram trajectory, and then the rotating rod 4 and the connecting rod 11 are rotated to fit with the bed frame 1 for storage; and in order to keep the bed frame 1 and the mattress 2 horizontally unfolded smoothly, the rotating rod 4 and the supporting rod 6 are set to have the same length, so that the four corners of the bed frame 1 are kept stable on the ground for support.

[0032] For more details, see Figure 1-5The support members 3 and the rotating rods 4 are respectively arranged in pairs at the two ends of the bed frame 1, and a connecting rod 16 is fixedly connected between the paired support members 3 and the rotating rods 4. The connecting rod 16 between the support members 3 is also provided with a hook spring 17 at one end of the bed frame 1 close to the support member 3.

[0033] In this embodiment, in order to make the rotating rods 4 arranged in pairs at the same end of the bed frame 1 consistent during the rotation and folding process, a connecting rod 16 is fixedly connected between the two rotating rods 4 to keep the two rotating rods 4 linked and then folded synchronously to keep the consistency of the two rotating rods 4. At the same time, the elasticity of the hook spring 17 provides elastic assistance during the lifting process of the bed frame 1 to reduce the user's force burden. In the process of the bed frame 1 rotating from a vertical state to a horizontal state, a buffer is formed by the elasticity of the hook spring 17 to prevent the bed frame 1 from rotating and lowering too quickly due to its own gravity, resulting in injury to the user or the ground, thereby improving the safety of the bed frame 1 during the rotation, folding and unfolding process.

[0034] More preferably, referring to Figure 1-5 The length of the connecting plate 9 is smaller than the length of the rotating rod 4 and the supporting rod 6, and the connecting rod 12 is arranged in an arched or straight rod shape.

[0035] In this embodiment, when the bed frame 1 and the mattress 2 are horizontally unfolded for rest or sleeping, in order to avoid the connection plate 9 being too long and causing conflict with the ground, thereby affecting the stability of the bed frame 1 and the mattress 2, the length of the connection plate 9 is set to be smaller than the length of the rotating rod 4 and the supporting rod 6, so that after the four corners of the bed frame 1 are supported by the rotating rod 4 and the supporting rod 6, there is a gap between the connection plate 9 and the ground, avoiding direct conflict between the connection plate 9 and the ground, thereby improving the practicality of the folding bed; because the upper end surface of the desktop 10 needs to bear weight when the desk 5 is used for storage or work or study, the connection rod 12 is set to be arched to effectively absorb and bear the weight, thereby keeping the load of the desk 5 stable; when it is set to be a straight rod, the transmission stroke between the positioning rod 8 and the desktop 10 can be shortened, so that the transmission of the connection rod 12 is more stable and fast.

[0036] More preferably, referring to Figure 1-5 The bottom end of the rotating rod 4 is threadedly connected with an adjusting foot pad 13, and the adjusting foot pad 13 is made of plastic material.

[0037] In the present embodiment, during the process of the bed frame 1 and the mattress 2 being restored to the horizontal state by rotation, since the rotating rod 4 needs to form a stable support after contacting the ground, in order to avoid instability caused by the unevenness of the ground contacted by the adjusting rotating rod 4, an adjusting foot pad 13 is threadedly connected to the bottom end of the rotating rod 4, so that the overall length of the rotating rod 4 can be adjusted by rotating the adjusting foot pad 13, so that the rotating rod 4 can adapt to the unevenness of the ground and maintain stable support, thereby maintaining the overall stability of the bed frame 1.

[0038] Furthermore, refer to Figure 1-5 The fixing rod 7 is an "L"-shaped flat iron with a turning portion, and a bolt groove and a bolt hole are respectively penetrated on the rod body and the turning portion of the fixing rod 7. The fixing rod 7 maintains an adjustable bolt connection with the bottom of the support member 3 through the bolt groove. The turning portion of the fixing rod 7 is set in contact with the wall and fixedly connected to the wall through the bolt hole; the end of the bed frame 1 close to the support member 3 is rotationally limited by the interference with the support rod 6.

[0039] In this embodiment, in order to provide a stable support point during the rotation and folding of the bed frame 1 and the mattress 2, the turning portion of the fixing rod 7 is arranged to be close to the wall and fixedly connected to the wall through the bolt hole, so that the bed frame 1 and the mattress 2 can maintain rotation stability during the rotation with the support member 3 as the fulcrum, and prevent the support member 3 from sliding and causing the bed frame 1 and the mattress 2 to rotate unsmoothly; at the same time, the bed frame 1 is parallel to the wall after rotation and folding, and in order to avoid the mattress 2 from rubbing and colliding with the wall when the thickness of the mattress is too large, the fixing rod 7 is arranged to be connected to the support member 3 through the bolt groove. 3, the bottom of the bed frame 1 is kept in an adjustable bolt connection, so that the fixing rod 7 can be adjusted through the bolt groove, so that the distance between the wall and the bed frame 2 can be adjusted to adapt to the thickness of the mattress 2; and in the rotation process of the bed frame 1 and the mattress 2, in order to prevent the bed frame 1 and the mattress 2 from rotating excessively and causing the mattress 2 to fall on the ground, the end of the bed frame 1 is set to contact with the support rod 6 to perform rotation limit, so as to prevent the bed frame 1 and the mattress 2 from rotating excessively, thereby maintaining the stability of the vertical folding of the bed frame 1 and the mattress 2, and at the same time, the mattress 2 can also form a side support through the wall to prevent the mattress 2 from tipping over.

[0040] Furthermore, refer to Figure 1-5 A limiting member 14 is fixedly mounted on one end of the bed frame 1 close to the supporting member 3 . The limiting member 14 protrudes from the upper end surface of the bed frame 1 and limits one end of the mattress 2 .

[0041] In this embodiment, when the bed frame 1 and the mattress 2 are rotated from a horizontal state to a vertical state, the bottom of the mattress 2 loses the support of the bed frame 1, and the weight of the mattress 2 itself will cause the mattress 2 to fall to the ground. At this time, a limiting member 14 is provided to provide limiting support for one end of the mattress 2 in the vertical state to keep the vertical state of the mattress 2 stable.

[0042] More specifically, see Figure 1-5 A plurality of support bars 15 are threadedly connected to the upper end surface of the bed frame 1 and the mattress 2 is supported by the support bars 15 .

[0043] In this embodiment, when the bed frame 1 and the mattress 2 are in a horizontal state for resting or sleeping, since the bed frame 1 as a whole is only a frame structure, in order to maintain stable support for the mattress 2, a plurality of support bars 15 are provided on the upper end surface of the bed frame 1 to support and keep the mattress 2 horizontal and stable.

[0044] Working principle:

[0045] The desk-integrated folding bed of the utility model, when the bed body is unfolded and used normally, the four corners of the bed frame 1 are supported by the rotating rod 4 and the supporting rod 6, so that the bed frame 1 and the mattress 2 are kept horizontal and stable for rest and sleep. At this time, the desk 5 is folded under the bed frame 1 for storage; and when the mattress 2 is idle, the end of the bed frame 1 away from the supporting member 3 is lifted, so that the bed frame 1 drives the mattress 2 to rotate as a whole with the top of the supporting rod 6 as the fulcrum, and due to the connecting rod 11 rotatably connected between the rotating rod 4 and the supporting rod 6, the bed frame 1, the rotating rod 4, the connecting rod 11, and the supporting rod 6 form a parallelogram, and then in the process of the bed frame 1 and the mattress 2 rotating, the rotating rod 4 and the connecting rod 11 parallel to the bed frame 1 and the supporting rod 6 are driven to rotate synchronously with the trajectory of the parallelogram, so that the rotating rod 4 and the connecting rod 11 are rotated and folded, so that the rotating rod 4 and the connecting rod 11 are close to the bed frame 1 for storage;

[0046] During the rotation of the bed frame 1 and the mattress 2, the support member 3 is also fixedly connected to the wall and the ground through the fixing rod 7 and the bolt holes on the turning part of the fixing rod 7, so as to form a stable support for the bed frame 1. As the bed frame 1 is continuously lifted and rotated, the end of the bed frame 1 close to the support member 3 contacts the side of the support rod 6, thereby limiting the rotation of the bed frame 1, so that the bed frame 1 can only rotate to a vertical state. At the same time, the bottom end of the mattress 2 in the vertical state is supported by the limiting member 14, and the mattress 2 in the vertical state is supported laterally by the wall to prevent the mattress 2 from tipping over. The elasticity of the hook spring 17 provides elastic assistance during the lifting of the bed frame 1 to reduce the user's force burden, and can also keep the bed frame 1 in a stable vertical state through the elasticity of the spring. In the process of the bed frame 1 rotating from the vertical state to the horizontal state, the elasticity of the hook spring 17 also forms a buffer to prevent the bed frame 1 from rotating too fast due to its own gravity.

[0047] At the same time, during the process of the bed frame 1 and the mattress 2 rotating from a horizontal state to a vertical state, the desk 5 rotatably connected to the middle part of the lower end surface of the bed frame 1 will also be synchronously driven to be lifted synchronously, and the middle part of the desktop 10 is rotatably connected to the end of the positioning rod 8 through the connecting rod 12. Therefore, during the overall lifting of the desk 5, it will also be pulled and supported by the connecting rod 12, so that the desk 5 as a whole always remains in a horizontal state. After the bed frame 1 and the mattress 2 are rotated to be vertically folded, the desk 5 as a whole is unfolded from under the bed frame 1, so that the upper end surface of the desktop 10 provides space for working and studying; while the vertical folding of the bed frame 1 and the mattress 2 increases the indoor activity space, the space under the bed frame 1 is exposed, which is convenient for cleaning and maintenance of the space under the bed.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
