[0038] Embodiment 1
[0039] The manual adjustable bed provided in this embodiment, as Figures 1-8 shown, includes: a bed frame 1, a fixed bed board 2 is fixedly installed on the upper part of the bed frame 1, both ends of the fixed bed board 2 are hinged with a movable bed board 3, a cross bar 301 is fixedly installed on each movable bed board 3, and a set of angle adjustment mechanisms 5 are installed between each cross bar 301 and the bed frame 1. The angle adjustment mechanism 5 is used to adjust the tilt angle of the movable bed board 3 to meet the needs of different users.
[0040] Specifically, in this embodiment, each set of angle adjustment mechanisms 5 includes two fixed frames 503, two intermediate baffles 504, a positioning rod 501 and a connecting rod 502. The two fixed frames 503 are symmetrically and fixedly installed on both sides of the bed frame 1, and a number of angle adjustment slots 505 are opened at the bottom of the inner frames of the two fixed frames 503. The two intermediate baffles 504 are symmetrically and fixedly installed on both sides of the bed frame 1. The intermediate baffle 504 on the same side is located in the inner frame of the fixed frame 503 on the same side, and there are gaps between both ends of the intermediate baffle 504 on the same side and the inner frame of the fixed frame 503 on the same side. Elastic expansion pins 507 are installed at both ends of the positioning rod 501. The elastic expansion pins 507 can be inserted into the angle adjustment slots 505 at corresponding positions, and the elastic expansion pins 507 can pass through the gaps. One end of the connecting rod 502 is fixedly connected to the positioning rod 501, and the other end of the connecting rod 502 is hinged to the cross bar 301.
[0041] Specifically, in this embodiment, the elastic expansion pin 507 includes a sealing cap 5071, a resisting seat 5074, a return spring 5073 and a cylindrical pin 5072. The sealing cap 5071 is fixedly installed at the end of the positioning rod 501, and a guiding hole 5075 is centrally opened on the sealing cap 5071. The resisting seat 5074 is fixedly installed inside the end of the positioning rod 501. The return spring 5073 abuts between the resisting seat 5074 and the cylindrical pin 5072, and the return spring 5073 is located inside the end of the positioning rod 501. Under the action of the return spring 5073, one end of the cylindrical pin 5072 passes through the guiding hole 5075 and extends to the outside of the sealing cap 5071, and the cylindrical pin 5072 can be inserted into the angle adjustment slot 505.
[0042] When the angle adjustment mechanism 5 adopting the above scheme is in use, the movable bed board 3 is lifted so that the cylindrical pin 5072 is inserted into the angle adjustment slot 505. The cylindrical pin 5072 can be inserted into different angle adjustment slots 505 according to needs. The difference between the angle adjustment mechanism 5 designed in this application and the adjustment mechanism in the prior art is:
[0043] When the movable bed board 3 is lifted to the highest position and continues to be lifted, the cylindrical pin 5072 can pass through the gap near the middle of the bed frame 1 and enter the space between the upper part of the middle baffle 504 and the top of the inner frame of the fixed frame 503. Then, the movable bed board 3 is released. Under the action of the gravity of the movable bed board 3, the cylindrical pin 5072 slides towards the gap away from the middle of the bed frame 1 until it falls into the space between the bottom of the middle baffle 504 and the bottom of the inner frame of the fixed frame 503 through the gap. At this time, the movable bed board 3 is in a horizontal state. Then, the movable bed board 3 is lifted so that the cylindrical pin 5072 is stuck in the angle adjustment slot 505, and the inclination angle of the movable bed board 3 can be adjusted again. During the whole process of adjusting the inclination angle until the movable bed board 3 is in a horizontal state, the cylindrical pin 5072 always moves counterclockwise along the outer peripheral track of the middle baffle 504. The operation method is novel and interesting, which can greatly improve the operation experience.
[0044] Specifically, in this embodiment, in order to enable the cylindrical pin 5072 to smoothly enter the gap of the middle baffle 504 away from the middle of the bed frame 1, guide blocks 506 are fixedly installed on both sides of the upper part of the bed frame 1 and outside the fixed frame 503. When the end of the cylindrical pin 5072 extending outside the sealing cap 5071 abuts against the guide block 506, it can completely retract into the guide hole 5075. A guide inclined cut is provided on the inner side of one end of the guide block 506 facing the middle of the bed frame 1, so as to facilitate the cylindrical pin 5072 to contract towards the guide hole 5075 smoothly under the guiding action of the guide inclined cut, enabling the cylindrical pin 5072 to smoothly enter the gap away from the middle of the bed frame 1, and thus smoothly completing the angle adjustment operation of the movable bed board 3.
[0045] Specifically, in this embodiment, in order to improve the structural stability of the angle adjustment mechanism 5, each set of the angle adjustment mechanism 5 is provided with two connecting rods 502, and the two connecting rods 502 are symmetrically arranged between the cross bar 301 and the positioning rod 501.
[0046] Specifically, in this embodiment, in order to facilitate the stable placement of the bed frame 1, legs 4 are fixedly installed at the bottom of the bed frame 1. In order to improve the anti-slip effect of the legs 4, plastic sheaths are sleeved on the bottom ends of the legs 4.
[0047] Specifically, in this embodiment, in order to improve the comfort, wire meshes are fixedly installed on the upper part of the fixed bed board 2 and the upper part of the movable bed board 3.
[0048] Specifically, in this embodiment, in order to facilitate the operation of the movable bed board 3, handles 302 are fixedly installed on the upper parts of the ends of the movable bed board 3 away from the fixed bed board 2.
[0049] It should be noted that the cylindrical pin 5072 is T-shaped, and the end in contact with the return spring 5073 is larger, which can prevent it from completely popping out of the guide hole 5075 and affecting the use.
[0050] Meanwhile, when the cylindrical pin 5072 is snapped into the angle adjustment slot 505, it abuts against the inner side wall of the bed frame 1, which can prevent the cylindrical pin 5072 from shaking. At the same time, when it is snapped into different angle adjustment slots 505, it gives people a certain sense of force, which can greatly improve the operation experience.
[0051] The difference between this embodiment and Embodiment 1 is that in order to enable the movable bed board 3 to be reset smoothly and lie flat, a pulling auxiliary component 6 is provided between the positioning rod 501 and the end of the bed frame 1. The pulling auxiliary component 6 includes a first spring seat 601, a second spring seat 602 and a pulling spring 603. The first spring seat 601 is fixedly installed at the end of the bed frame 1, the second spring seat 602 is fixedly installed on the positioning rod 501, and the pulling spring 603 is installed between the second spring seat 602 and the first spring seat 601. Under the action of the pulling spring 603, the movable bed board 3 can be reset smoothly and lie flat.
[0052] In summary, the manual adjustable bed provided by this embodiment has the following advantages:
[0053] When the angle adjustment mechanism 5 is used, the movable bed board 3 is lifted so that the cylindrical pin 5072 is snapped into the angle adjustment slot 505. The cylindrical pin 5072 can be snapped into different angle adjustment slots 505 according to needs. The difference between the angle adjustment mechanism 5 designed in this application and the adjustment mechanism in the prior art is:
[0054] When the movable bed board 3 is lifted to the highest position and then lifted further, the cylindrical pin 5072 can pass through the gap near the middle of the bed frame 1 and enter the upper part between the middle baffle 504 and the inner frame top of the fixed frame 503. Then the movable bed board 3 is released. Under the gravity of the movable bed board 3, the cylindrical pin 5072 slides towards the gap away from the middle of the bed frame 1 until it falls through the gap into the bottom between the middle baffle 504 and the inner frame bottom of the fixed frame 503. At this time, the movable bed board 3 is in a horizontal state. Then the movable bed board 3 is lifted so that the cylindrical pin 5072 is snapped into the angle adjustment slot 505, and the inclination angle of the movable bed board 3 can be adjusted again. During the whole process of adjusting the inclination angle until the movable bed board 3 is in a horizontal state, the cylindrical pin 5072 always moves counterclockwise along the outer peripheral trajectory of the middle baffle 504. The operation method is novel and interesting, which can greatly improve the operation experience.
[0055] The above is only a preferred embodiment of the present invention, and it does not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be able to realize that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
