Description

A foldable screen

technical field

The utility model belongs to the technical field of furniture and relates to a screen, in particular to a screen that can be opened and closed.

Background technique

Screen is a commonly used home decoration item, but the existing screens are generally integral and relatively large in size, which is very inconvenient to carry and store. For this reason, the Chinese patent [authorized announcement number: CN201260520Y] discloses a foldable screen, the foot support at the lower end of the screen rod and the screen fan between the screen rods, the screen shaft is fixed inside the screen rod, and one side of each screen fan It is connected with the screen shaft that is close to it, so that the screen fan can be rolled into the screen rod with the rotation of the screen shaft. inside the chute. There are two sections of poles perpendicular to the screen poles between adjacent screen poles. The two sections of poles are movable hinges. The foot supports and diagonal supports can be retracted into the chute, and the foldable poles can make the screen poles move closer. , the screen fan can be rolled into the screen rod. Although the screen of this design can reduce the screen occupation to a certain extent and is convenient for storage, but because it has multiple screen rods and there is no direct connection between each screen rod, it is not stable enough to be placed during storage, and the occupied space is still relatively large. larger.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems in the existing technology, and propose an openable screen, which can realize opening and closing, and has a small storage volume.

The purpose of this utility model can be achieved through the following technical solutions: a screen that can be opened and closed is characterized in that it includes a base, a fixed plate, several support rods and a screen cloth arranged on the support rods, the fixed plate and The bases are fixedly connected, and the bottom of each support rod is hinged on the fixing plate through detachable bolt assemblies.

In this technical solution, each support rod is connected to the base through a bolt assembly. Since the bolt assembly is a detachable structure, one or more support rods can be wound around the axis of the bolt by loosening the bolt assembly. When the rotation is in place, re-tighten the bolt assembly to realize the repositioning of the bracket rod, so as to realize the opening and closing of the screen, ensure the stability of the screen in normal use, and increase the storage volume of the screen when it is not in use smaller.

In the above-mentioned openable screen, the support rods include vertical support rods, oblique support rods and horizontal support rods, the vertical support rods are arranged vertically, and the bottom of the vertical support rods is fixed to the fixing plate connected, the bottom of the oblique support rod is hinged to the fixed plate, and the oblique support rod can rotate around the hinge point of the oblique support rod and the fixed plate, the bottom of the horizontal support rod is hinged to the fixed plate, and The horizontal support rod can rotate around the hinge point between the oblique support rod and the fixed plate. The oblique support rods and the horizontal support rods are hinged with the base, and they can respectively rotate relative to their respective hinge points with the base to realize the opening and closing operation of the screen, and when they are folded, they can respectively move closer to the vertical support rods. Left and right sides, reducing storage volume.

In the aforementioned openable and closable screen, the fixed plate is L-shaped and includes a vertically arranged straight plate portion and a horizontally arranged horizontal plate portion, the bottom of the support rod is connected to the straight plate portion, and the horizontal plate portion Attached to the base with fasteners. The fixing plate is made by bending the plate, and the bracket rod is directly connected to the straight plate part through the bolt assembly, so the positioning is firmer, the rotation is more flexible, and the opening and closing of the screen is more convenient. The base plate has a downward opening groove, the The recess may be used to accommodate a nut or a nut of a bolt in a bolt assembly. The fasteners in the technical method can be bolts, screws or positioning pins and the like.

In the above-mentioned openable screen, the screen cloth has several cloth covers distributed in a fan shape and capable of being fitted on the support rod. When the support rod rotates, it can drive the screen cloth to open and close, and the screen cloth in the technical solution can only be installed or disassembled when the support rod is folded, which can ensure the stability of the screen cloth when the screen is opened and closed.

In the aforementioned openable and closable screen, the straight part has a connection hole 1 for connecting the vertical support rod, a connection hole 2 for connecting the oblique support rod and a connection hole 3 for connecting the horizontal support rod, The first connecting hole, the second connecting hole and the third connecting hole are arranged in an arc. The connecting shafts of each support rod and the fixing plate are located on the same circular arc, and when the support rod rotates to realize the opening and closing of the screen, it can also ensure that the screen cloth set on the support rod will not be displaced or come out.

Compared with the prior art, the utility model has the following advantages:

1. The bracket rod is hinged with the base, which can realize the opening and closing of the screen, and at the same time can make the volume of the screen smaller after being folded;

2. The screen cloth is firmly fixed when the screen is unfolded, and it is not easy to shift and fall out.
