Detailed Description
As shown in fig. 1 to 9, a pressing device for a drawer bottom plate, hereinafter referred to as a pressing device, is composed of a fixed seat 1, an elastic sheet 2, an adjusting screw, a stop nut, a first spring seat 3, a spring and a second spring seat 4.
The fixing seat is fixed on a side plate behind the drawer bottom plate, one side of the fixing seat, which is far away from the drawer rear baffle plate, is provided with a screw connecting lug perpendicular to the fixing seat, one side of the fixing seat, which is close to the rear baffle plate, is provided with a stop connecting lug, and the stop connecting lug is provided with a screw hole.
After the drawers of the solid wood furniture are assembled, a pressing device is respectively arranged on the side plates on the two sides of the rear of each drawer rear baffle, the fixing seat is fixed on the side plates by screws firstly during installation, the fixing seat is fixed by at least two screws, and at least one screw hole on the fixing seat is a long hole so as to have certain adjusting capacity during installation. After the fixing seat is installed, the tail end of the adjusting screw penetrates through the screw connecting lug, then sequentially penetrates through the stop nut, the first spring seat, the spring and the second spring seat, then penetrates through the middle of the elastic sheet and then is screwed on the screw hole in the stop connecting lug, and the lower part of the elastic sheet is supported on the bottom plate from back to front.
The lower part of the elastic sheet is provided with a square bulge which is arched towards the direction far away from the front stop, and the bottom plate enters the inner cavity of the square bulge and is propped tightly.
The wall surface of the square protrusion facing the bottom plate is provided with a semicircular protrusion protruding towards the bottom plate, and the bottom plate is abutted against the semicircular protrusion.
The stop nut is screwed on the adjusting screw, and the elastic force of the spring enables the first spring seat to be tightly pressed on the stop nut and the second spring seat to be tightly pressed on the elastic sheet.
The distance between the stop nut and the stop lug can be changed by adjusting the position of the stop nut on the adjusting screw, so that the prestress of the spring is changed.
Or the position of the adjusting screw on the stop connecting lug can be changed by screwing the adjusting screw, so that the distance between the stop nut on the adjusting screw and the stop connecting lug is changed, and the prestress of the spring can be changed.
Through the two ways of changing the prestress of the spring, the force of the elastic sheet pressing the drawer bottom plate can be changed. The more the spring is compressed, the more tightly the elastic sheet can push the bottom plate to the direction of the front stop, otherwise, the force of the elastic sheet pushing the bottom plate to the direction of the front stop is weakened.
One or two stop nuts are preferably selected, so that the displacement can be effectively prevented, and the two stop nuts can tightly press the first spring seat to prevent the displacement of the stop nuts after long-time use.
The first spring seat is in a hollow cylindrical shape, and one end, far away from the drawer front stop, of the spring enters the hollow part of the first spring seat to prevent the spring from displacing.
The second spring seat is provided with a hollow column, and one end of the spring facing the drawer front stop enters the hollow part of the second spring seat. The spring is restrained on the adjustment screw between the first spring seat and the second spring seat.
The end face of the second spring seat far away from the spring is provided with a hemisphere which is arched outwards, and the outer wall of the hemisphere is abutted against the elastic sheet.
The fixing seat above the stop connecting lug is provided with a baffle plate, and the upper part of the elastic sheet is fixed through the baffle plate.
The blocking piece is perpendicular to the fixing seat, an elastic piece hole is formed in the blocking piece, and the upper portion of the elastic piece penetrates through the elastic piece hole from back to front, so that the elastic piece is not prone to swinging.
The tail end of the upper part of the elastic sheet is bent from front to back, so that the elastic sheet is not easy to be separated from the elastic sheet hole.
The shell fragment supports tight bottom plate forward from the back, when the bottom plate received expend with heat and contract with cold's influence to the direction extrusion of shell fragment when removing, the shell fragment also can extrude the spring by the bottom plate extruded, the spring receives the extrusion also can produce bigger tension when producing more deformations, thereby reduce the removal of bottom plate to the direction of shell fragment, when the bottom plate weakens to the extruded strength of the direction of shell fragment, the tension of spring can compress tightly the middle part of shell fragment, the direction extrusion bottom plate that the lower part that makes the shell fragment kept off forward, thereby make the direction removal that the bottom plate kept off forward keep off until reaching before.
When the elastic sheet is required to have stronger or smaller force for pressing the bottom plate, the adjusting screw is screwed towards the front stop or away from the front stop.
In practical application, the fixing seat, and the screw connecting lug, the stop connecting lug and the blocking piece which are arranged on the two sides of the fixing seat are punched on one section. Firstly, a fixing seat, a screw connecting lug, a stop connecting lug and a blocking piece are punched from a plane section bar according to shapes, then a screw hole for installing the fixing seat on a drawer side plate is punched at a corresponding position on the fixing seat, and then the screw connecting lug, the stop connecting lug and the blocking piece are respectively bent to be vertical to the fixing seat.
In order to stabilize the position of the screw screwed on the stop connecting lug, a small hole is punched on the stop connecting lug, the edge of the small hole is extruded outwards along the periphery of the small hole to form a larger hole integrated with the stop connecting lug, and then the screw thread matched with the adjusting screw is formed in the hole.
The upper part of the elastic sheet is fixed through the blocking sheet, the middle part of the elastic sheet is fixed on the adjusting screw, the middle part of the elastic sheet is influenced by the tension of the spring, the spring extrudes the elastic sheet forwards, the bottom plate of the drawer pushes the lower part of the elastic sheet backwards when the bottom plate expands thermally, the bottom plate can not move backwards greatly through the counter balance between the backward pushing force of the bottom plate and the forward tension of the spring, the bottom plate is kept at a proper position, and the phenomenon that objects in the drawer fall downwards from a gap due to the fact that the gap between the bottom plate and the front block is too large.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
