Description
Technical Field
The utility model relates to a living furniture, in particular to a double-layer bed air pressure bed box.
Background
The bunk bed is a piece of furniture commonly used in daily life, and generally, a pull-out type bed box is arranged below the bunk bed, and when the bed box is pulled out, the bunk bed can also be used as a bed. In order to make full use of the space of the bed box, the bed plates of the bed box are generally openable, so that the interior of the bed box can be used for storing articles.
For example, the chinese patent discloses a pneumatic lifting device (CN 204181282U) for bed box, which comprises a four-bar lifting mechanism and a gas spring, wherein the four-bar lifting mechanism is fixed and connected to two inner plate walls of the bed box in bilateral symmetry, and the gas spring is connected to the four-bar lifting mechanism. The four-bar lifting mechanism comprises four independent rigid bodies, wherein two bar ends of the connecting bar are respectively and fixedly connected with a stressed rocker and a connecting rocker, the other ends of the stressed rocker and the connecting rocker are rotatably connected to vertical planes on two sides of an angle bar of the steering connecting bar, the steering connecting bar is hinged to a steering knuckle to longitudinally extend through the stress rocker, the length of the stressed rocker is greater than that of the connecting rocker, one end of the air spring is fixedly hinged to the steering knuckle of the stressed rocker, and the other end of the air spring is connected to a limit steering knuckle at the extending part of the steering connecting bar, so that the air pressure lifter is formed.
The bed board can be opened and closed on the bed box by the air pressure lifter, the storage function in the bed box is realized, but the lifting structure has the following problems: under the action of the air pressure lifter, the opening angle of the bed plate is fixed, and if a large object needs to be stored, the opening angle of the bed plate needs to be large; however, if the opening angle of the bed board is designed to be larger, the bed board is inconvenient to use and is not suitable to be opened and closed, and bedding on the bed board slides down.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a bunk beds atmospheric pressure bed case is adjustable through the jacking angle design with atmospheric pressure lift to solve the problem of bed board opening angle adjustable.
The utility model discloses a following technical scheme realizes: a double-layer bed air pressure bed box comprises a box body and a bed plate buckled at an opening at the upper end of the box body; an air pressure lifter is connected between the box body and the bed plate; the pneumatic lifter comprises a four-bar mechanism formed by sequentially hinging a front rocker, a bottom frame, a rear rocker and an upper connecting bar; an air spring rod is hinged between the front end of the upper connecting rod and the front rocker; the front end of the upper connecting rod is provided with a main sliding chute, and the upper side of the main sliding chute is provided with positioning grooves which are uniformly distributed; a limit pin is fixed at the upper end of the gas spring rod and is arranged in the locating slot.
The limiting pin is arranged in the main sliding groove in a sliding mode, and the main sliding groove and the positioning groove are communicated through an inclined sliding way.
Compared with the prior art, the beneficial effects of the utility model are that: when the bed is used in normal times, the limiting pin at the upper end of the air spring rod is arranged in the positioning groove at the outermost side, and the opening angle of the bed plate is smaller, so that the operation is convenient; when a large object needs to be placed, the bed board is lifted upwards by a large angle, the limiting pin slides out of the positioning groove in the front side and enters the main sliding groove, and then the limiting pin slides into the positioning groove in the rear side, so that the opening angle of the bed board is increased, and the large object is convenient to place.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a double-deck pneumatic bed box comprises a box body 1 and a bed plate 2 fastened at an opening at the upper end of the box body 1; an air pressure lifter is connected between the box body 1 and the bed plate 2; the pneumatic lifter comprises a four-bar mechanism which is formed by sequentially hinging a front rocker 5, an underframe 6, a rear rocker 7 and an upper connecting bar 8; an air spring rod 4 is arranged between the front end of the upper connecting rod 8 and the front rocker 5.
