Description

Fitment wallboard that can assemble

Technical Field

The invention relates to the technical field of architectural decoration, in particular to an assembled decoration wallboard.

Background

The wall panel is a house structure of a bearing system consisting of walls and floor slabs, and can be divided into a mixed structure, an assembled large-plate structure and a cast-in-place wall panel structure according to different used materials and construction methods.

The traditional wall board is generally of a one-piece structure, and during installation, a hole is usually drilled in an indoor wall to install an expansion bolt or a wood plug with a similar function, then a keel made of wood or other materials is fixed on the wall, a bottom board (generally a cement board, a gypsum board and the like) is fixed in the keel, and finally wall paper and wall cloth are pasted on the surface layer of the bottom board or paint is sprayed on the surface layer of the bottom board for decoration.

However, the bottom plate of the wall plate is usually of an integrated structure, and is generally difficult to disassemble, assemble and replace, and particularly, when the bottom plate is locally damaged, only the whole bottom plate can be replaced, so that the engineering quantity is large, and the operation is troublesome.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the assembled decoration wallboard which has the effects of small dismantling and replacing work amount and simplicity and convenience in operation when the bottom plate is locally damaged.

In order to achieve the purpose, the invention provides the following technical scheme: an assembled decoration wallboard comprises a keel frame and a bottom plate, wherein the bottom plate comprises a plurality of fixing plates detachably arranged on the keel frame, one end of each fixing plate is hinged with the keel frame through a hinge piece, and the other end of each fixing plate is clamped with the keel frame through a clamping piece; the keel frame is in a grid shape and is provided with a plurality of mounting holes, and driving pieces for driving the movable end of the fixed plate to move to one side far away from the keel frame are arranged in the mounting holes; the driving piece comprises a driving plate and a rotating shaft arranged in the middle of the driving plate, and two ends of the rotating shaft are respectively and rotatably connected to the inner walls opposite to the mounting holes; one end of the fixing plate, which is close to the hinged end of the fixing plate, is provided with a moving hole, and a button used for pushing the driving plate is installed in the moving hole.

Through adopting above-mentioned technical scheme, the bottom plate is split into the independent fixed plate of polylith, and people need not to change other fixed plates together with when monolithic fixed plate is impaired, and the engineering volume when tearing open and changing is little, compares in tearing open and changing monoblock bottom plate convenient and fast more. When the driver is detached, the button is moved to one side close to the driver plate, so that one end, close to the hinged end of the fixing plate, of the driver plate moves to one side far away from the fixing plate. Because the drive plate articulates in the mounting hole through the pivot, the one end that the fixed plate hinged end was kept away from to the drive plate this moment can be to the one side removal that is close to the fixed plate to produce the effort of keeping away from keel frame one side towards the free end of fixed plate, the fixed plate uses the articulated elements to rotate as the centre of a circle under the effect of this effort, and with keel frame between produce the clearance, people can should point and stretch into in this clearance in order to stir the fixed plate and rotate, at last with impaired fixed plate and keel frame split can. The setting of button and driving piece has the effect that makes things convenient for people to increase fixed plate and keel frame clearance, is favorable to demolising of fixed plate.

The invention is further configured to: the button includes fixed connection's reset block and ejector pad, the ejector pad cunning is established in removing the hole, be equipped with on the fixed plate with remove the reset groove of hole intercommunication, reset groove is located the one side that the mounting hole was kept away from to the hole that removes, reset groove is equipped with reset spring on being close to the inner wall of mounting hole, reset spring's the other end and reset block fixed connection.

Through adopting above-mentioned technical scheme, when utilizing the button to drive the drive plate and remove, press the reset block with tools such as hand or member for reset spring pressurized deformation and production elasticity, ejector pad move to the one side that is close to the drive plate thereupon, move with the drive plate butt and drive plate and close one end rather than one side of keeping away from the fixed plate when the ejector pad removes. After the reset block is loosened, the reset block and the push block can automatically move to one side far away from the drive plate under the action of the reset spring, so that the automatic reset of the button is realized, and the reuse by people is facilitated.

The invention is further configured to: and a pushing groove for the pushing block to extend into is formed in the end face, close to the fixed plate, of the driving plate.

Through adopting above-mentioned technical scheme, one end stretches into in the lapse groove when the ejector pad promotes the drive plate, and the lapse groove plays the effect of restriction ejector pad migration range for the ejector pad during operation is difficult for producing relative movement by a wide margin with the drive plate, has improved the stability of ejector pad.

The invention is further configured to: the two ends of the driving plate are respectively provided with a limiting piece for limiting the rotation of the driving plate, wherein the limiting piece close to the hinged end of the fixing plate is positioned on one side of the driving plate far away from the fixing plate, and the limiting piece close to the movable end of the fixing plate is positioned on one side of the driving plate close to the fixing plate; the locating part includes fixed connection's stopper and spacing spring, all be equipped with the spacing groove on the relative inner wall of mounting hole, two the other end of spacing spring is connected respectively at two spacing inslots and drive rather than the stopper of being connected and stretch out the spacing groove, the stopper is close to the drive plate and all is equipped with the direction inclined plane with the one side of keeping away from the drive plate.

Through adopting above-mentioned technical scheme, the drive plate receives the difficult rotation of restriction of two locating parts during natural state for the drive plate can not contact with the fixed plate and lead to the free end and the keel frame separation of fixed plate, has still improved the stability of drive plate self simultaneously. The both ends of button during operation drive plate respectively with rather than close stopper butt for during the stopper compression is connected spacing spring and income spacing groove, the effect of direction is played in the drive plate removal in the direction inclined plane, has ensured the normal rotation of drive plate.

The invention is further configured to: and one side of the limiting block is provided with a butt joint block fixed on the inner wall of the mounting hole, and when the driving plate is in a vertical state, the two butt joint blocks are respectively butted on two sides of the driving plate.

Through adopting above-mentioned technical scheme, the butt piece can restrict the drive plate and move to one side that is close to the fixed plate with the close one end of button, and the both sides of drive plate all receive the restriction, have further improved the stability of drive plate.
