Technical Field

[0001] The utility model relates to the technical field of sofa beds, in particular to a three-section stretching sofa bed. Background Art

[0002] Sofa bed refers to a kind of furniture that can be used as both a sofa and a bed. Modern living room layout advocates simplicity, and multifunctional furniture is becoming more and more popular, and sofa bed is one of them.

[0003] The existing sofa bed has a poor support in the middle part of the bed frame, and the load is heavy, and the bed frame deforms and sinks when in use;

[0004] The reason for this problem is that most of the current sofa beds have three-section folding frames. When the sofa bed is unfolded and used as a bed, the middle part of the frame is usually located at the waist and hips of the human body, which will cause the middle part of the frame to be heavier. In order to facilitate the folding and storage of the frame, no supporting legs are set on the middle frame, resulting in poor support, which can easily cause the frame to deform and sink during use. In view of the shortcomings of the existing technology, we propose a three-section stretching sofa bed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The embodiment of the present application provides a three-section stretching sofa bed, which solves the problem that the bed frame in the middle part of the sofa bed has poor support, heavy load, and deformation and sinking of the bed frame during use.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a three-section stretching sofa bed.

[0027] According to the attached Figure 1-5 As shown, a three-section stretch sofa bed comprises a sofa frame 1 and a first bed frame 101, a second bed frame 2 and a third bed frame 3 arranged on the top of the sofa frame 1, a support assembly 4 is arranged between the second bed frame 2 and the third bed frame 3, and the support assembly 4 comprises:

[0028] A support rod 401 is provided at the bottom of the second bed frame 2. The support rod 401 is used to support the second bed frame 2, thereby avoiding the situation where the second bed frame 2 is poorly supported and easily causes the bed frame to bend;

[0029] The cross frame 402 is arranged at the bottom of the third bed frame 3 , and is used to fix the second bed frame 2 and the third bed frame 3 .

[0030] The second bed frame 2 is rotatably connected between the first bed frame 101 and the third bed frame 3. The first bed frame 101 is rotatably connected to the top of the sofa frame 1. A support frame 102 is fixedly connected to the inner side of the sofa frame 1. The support frame 102 is used to support the first bed frame 101. After the three sets of bed frames are unfolded, the support frame 102 can be rotated downward to support the second bed frame 2.

[0031] The two sides of the support rod 401 are fixedly connected with shaft rods 4011 , and the bottom of the second bed frame 2 is provided with a second slide groove 201 , and the shaft rod 4011 is rotatably connected inside the second slide groove 201 .

[0032] The side wall of the support rod 401 and the inside of the second slide groove 201 are both provided with a magnetic plate 4012, and the magnetic plate 4012 is used to fix the support rod 401. When the first bed frame 101 and the second bed frame 2 are folded and merged, the support rod 401 can be rotated upward and retracted into the second slide groove 201, and it can be fixed by the magnetic plate 4012, thereby preventing the support rod 401 from rotating at will.

[0033] A first slide groove 301 is provided at the bottom of the third bed frame 3, and the first slide groove 301 corresponds to the second slide groove 201. The cross frame 402 is slidably connected to the inside of the first slide groove 301 and the second slide groove 201. When the support frame 102 is rotated downward to support the second bed frame 2, the cross frame 402 in the first slide groove 301 is slid toward the second slide groove 201 until the end of the cross frame 402 is against the support frame 102. At this time, the cross frame 402 is placed between the first slide groove 301 and the second slide groove 201, which can not only support and fix the second bed frame 2 and the third bed frame 3, but also clamp and fix the support frame 102, thereby increasing the stability of the support frame 102.

[0034] A card block 4021 runs through the top of the horizontal frame 402. The first slide groove 301 and the second slide groove 201 are both provided with card slots 302. The card block 4021 is connected to the inside of the card slot 302. By pulling the card block 4021 downward and sliding it out of the card slot 302, the horizontal frame 402 can be moved.

[0035] The outer wall of the block 4021 is sleeved with a spring 4022, and both ends of the spring 4022 are fixedly connected to the block 4021. After the block 4021 is released, it will reset upward by the elastic force of the spring 4022. At this time, the block 4021 will be inserted into the slot 302 for fixation.

[0036] When the utility model is in use, the third bed frame 3 is first pulled outward until the third bed frame 3 drives the three sets of bed frames to be fully unfolded, and then the support rod 401 at the bottom of the second bed frame 2 is rotated downward for support, and then the block 4021 is pulled downward to slide out of the slot 302, and then the cross frame 402 is moved toward the second slide slot 201 until the end of the cross frame 402 abuts against the support frame 102, and then the block 4021 is released, and the block 4021 will be reset upward by the elastic force of the spring 4022, and inserted into the slot 302 for fixation, and finally the mattress is spread on the three sets of bed frames and it can be used as a bed for rest.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
