The present disclosure relates to the technical field of adjustable beds, and in particular to, a manually adjustable bed.
An adjustable bed is generally adjustable in height or an angle of a bed board, which can meet the needs of different users. Main adjustment methods include electric adjustment, hydraulic adjustment, or manual adjustment. In the scheme for manually adjusting the angle of the bed board, the angle is usually adjusted in a hand-operated manner by using a screw rod for driving or by cooperation between a clamping slot and a clamping block. Although all these methods can meet the usage need for adjusting the angle of the bed board, the above operation methods are too ordinary and boring, resulting in a poor operating experience. Therefore, a manually adjustable bed is proposed.
The present disclosure aims to solve the problems in the background section, and provides a manually adjustable bed.
Specific technical solutions are as follows:
A manually adjustable bed includes:

As a preferred solution of the present disclosure, each elastically telescopic pin includes a sealing cap, a resisting seat, a reset spring, and a cylindrical pin; the scaling cap is fixedly mounted at an end portion of the positioning rod; a guide hole is centrally formed in the sealing cap; the resisting seat is fixedly mounted in the end portion of the positioning rod; the reset spring resists between the resisting seat and the cylindrical pin; the reset spring is located in the end portion of the positioning rod; one end of the cylindrical pin extends out of the sealing cap through the guide hole under the action of the reset spring; and the cylindrical pin can be clamped into the adjustment clamping slot.
As a preferred solution of the present disclosure, guide blocks are fixedly mounted on two sides of the upper part of the bed frame and on outer sides of the fixed frames; and when ends of the cylindrical pins extending out of the sealing caps resist against the guide blocks, the cylindrical pins can fully retract into the guide holes.
As a preferred solution of the present disclosure, each group of angle adjustment mechanism includes two connecting rods; the two connecting rods are symmetrically arranged between the cross rod and the positioning rod.
As a preferred solution of the present disclosure, supporting legs are fixedly mounted at a bottom of the bed frame.

According to the manually adjustable bed provided in the present disclosure, when the movable bed boards continue to be lifted after being lifted to the highest positions, the cylindrical pins can enter a space between the upper parts of the middle baffle plates and the tops of the inner frames of the fixed frames through the gaps close to the middle of the bed frame, and the movable bed boards are then released. Under the action of the gravity of the movable bed boards, the cylindrical pins slide towards the gaps away from the middle of the bed frame until the cylindrical pins fall into a space between the bottoms of the middle baffle plates and the bottoms of the inner frames of the fixed frames through the gaps. At this time, the movable bed boards are in a horizontal state, and the movable bed boards are lifted to clamp the cylindrical pins into the angle adjustment slots to adjust the inclination angles of the movable bed boards again. In the entire process of adjusting the inclination angles until the movable bed boards are in the horizontal state, the cylindrical pins move counterclockwise along a trajectory of peripheral edges of the middle baffle plates all the time. The operation method is new and interesting, and the operation experience can be greatly enhanced.

When the angle adjustment mechanisms 5 of the above solution are used, the movable bed boards 3 are lifted to clamp the cylindrical pins 5072 into the angle adjustment clamping slots 505, so that the cylindrical pins 5072 can be clamped into different angle adjustment clamping slots 505 according to a need. A difference between the angle adjustment mechanisms 5 designed in the present disclosure and an adjustment mechanism in the prior art is that:
When the movable bed boards 3 continue to be lifted after being lifted to the highest positions, the cylindrical pins 5072 can enter a space between the upper parts of the middle baffle plates 504 and the tops of the inner frames of the fixed frames 503 through the gaps close to the middle of the bed frame 1, and the movable bed boards 3 are then released. Under the action of the gravity of the movable bed boards 3, the cylindrical pins 5072 slide towards the gaps away from the middle of the bed frame 1 until the cylindrical pins fall into a space between the bottoms of the middle baffle plates 504 and the bottoms of the inner frames of the fixed frames 503 through the gaps. At this time, the movable bed boards 3 are in a horizontal state. The movable bed boards 3 are then lifted to clamp the cylindrical pins 5072 into the angle adjustment slots 505 to adjust the inclination angles of the movable bed boards 3 again. In the entire process of adjusting the inclination angles until the movable bed boards 3 are in the horizontal state, the cylindrical pins 5072 move counterclockwise along a trajectory of peripheral edges of the middle baffle plates 504 all the time. The operation method is new and interesting, and the operation experience can be greatly enhanced.
Specifically, in this embodiment, to enable the cylindrical pins 5072 to successfully enter the gaps of the middle baffle plates 504 away from the bed frame 1, guide blocks 506 are fixedly mounted on two sides of the upper part of the bed frame 1 and on outer sides of the fixed frames 503; and when ends of the cylindrical pins 5072 extending out of the sealing caps 5071 resist against the guide blocks 506, the cylindrical pins can fully retract into the guide holes 5075. Oblique guide incisions are provided on inner sides of ends of the guide blocks 506 facing the middle of the bed frame 1, so that the cylindrical pins 5072 can successfully retract into the guide holes 5075 through the guide action of the oblique guide incisions, and the cylindrical pins 5072 can successfully enter the gaps away from the middle of the bed frame 1, thereby successfully completing the angle adjustment operation on the movable bed boards 3.
Specifically, in this embodiment, to improve the structural stability of the angle adjustment mechanisms 5, each group of angle adjustment mechanism 5 includes two connecting rods 502; and the two connecting rods 502 are symmetrically arranged between the cross rod 301 and the positioning rod 501.
Specifically, in this embodiment, to facilitate stable placement of the bed frame 1, supporting legs 4 are fixedly mounted at a bottom of the bed frame 1. To improve the antiskid effect of the supporting legs 4, bottom ends of the supporting legs 4 are all sleeved with plastic sheaths.

It is worth mentioning that the cylindrical pins 5072 are T-shaped, and ends of the cylindrical pins that are in contact with the reset springs 5073 are large, so that the impact on use caused by the fact that the cylindrical pins pop up completely from the guide holes 5075.
Meanwhile, when clamped into the angle adjustment clamping slots 505, the cylindrical pins 5072 resist against the inner side wall of the bed frame 1. In this way, the cylindrical pins 5072 can be prevented from shaking. Moreover, a user may feel it when the cylindrical pins are clamped into different angle adjustment clamping slots 505, which can greatly enhance the operation experience.
A difference between this embodiment and Embodiment 1 is that: To enable the movable bed boards 3 to be successfully reset and lie flatly, a pulling-assisted assembly 6 is arranged between the positioning rod 501 and an end portion of the bed frame 1; the pulling-assisted assembly 6 includes a first spring seat 601, a second spring seat 602, and a pull spring 603; the first spring seat 601 is fixedly mounted at the end portion of the bed frame 1; the second spring seat 602 is fixedly mounted on the positioning rod 501; and the pull spring 603 is mounted on the second spring seat 602 and the first spring seat 601. Under the action of the pull spring 603, the movable bed boards 3 can be successfully reset and lie flatly.
