Detailed Description
The core of the invention is to provide a side hung door limiting device, which can realize limiting in two states of opening and closing a cabinet door and prevent the cabinet door from moving accidentally.
In order to make those skilled in the art better understand the technical solution of the present invention, the vertical hinged door limiting device and the cabinet of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, which is a schematic structural diagram of the side hung door limiting device of the present invention, the side hung door limiting device of the present invention is applied to a cabinet door that can be opened in a turnover manner, and is used for limiting an open state and a closed state of the cabinet door. The vertical hinged door limiting device comprises a limiting part 1, wherein the limiting part 1 can adopt a plate-shaped structure, an arc-shaped groove 2 is formed in the limiting part 1, and the widths of all positions of the arc-shaped groove 2 are basically equal; the arc-shaped groove 2 can be in the form of a through hole penetrating through the whole limiting part 1, and can also be in the form of a blind hole if the structure of the limiting part 1 is thicker.
The arc-shaped groove 2 is approximately C-shaped and slightly provided with a certain radian, and the arc-shaped groove 2 can be an arc or an arc with unequal curvatures at each part; two ends of the arc-shaped groove 2 are respectively provided with a limiting groove 3, the limiting grooves 3 are mutually communicated with the arc-shaped groove 2, the width of each limiting groove 3 is larger than that of the arc-shaped groove 2, and the two limiting grooves 3 respectively form an approximate L-shaped structure at two ends of the arc-shaped groove 2; smooth transition is formed between the arc-shaped groove 2 and the limiting groove 3, and smooth step-shaped transition is formed between the arc-shaped groove 2 and the limiting groove 3.
Spacing part 1 rotates to be connected on the cabinet body, and its axis of rotation is vertical setting, and spacing part 1 can rotate in the horizontal plane, and the orientation of seting up of arc wall 2 is vertical along, and is mutually perpendicular with the pivot direction. The cabinet door is provided with a limiting pin 4, and the limiting pin 4 can move synchronously with the cabinet door.
Fig. 2 is a schematic diagram of the vertical hinged door limiting device of the present invention, and a cabinet door and a cabinet body are assembled relatively, where a represents the cabinet body, B represents the cabinet door, a limiting component 1 is connected with the cabinet body through a rotating shaft, and the limiting component 1 can rotate along a direction indicated by an arrow in the figure.
The limiting pin 4 is inserted in the arc-shaped groove 2 and respectively positioned in the limiting grooves 3 at the two ends when the cabinet door is in a closed state and a maximum opening state; shown in fig. 2 that the cabinet door is in the closed condition, this moment spacer pin 4 is arranged in left spacing recess 3, when the cabinet door is opened to needs, needs exert certain external force to the vertical hinged door, makes spacer pin 4 overcome the blockking that spacing recess 3 caused, can get into arc wall 2 to make the cabinet door open smoothly.
According to the side hung door limiting device, when the cabinet door is opened or closed in a rotating mode, the limiting pin rotates along with the cabinet door, when the limiting pin is located in the limiting grooves at the two ends, the limiting pin is clamped into the limiting grooves under the action of elastic force of the elastic piece to achieve clamping limiting, the limiting pin 4 can be stably sunk into the limiting grooves 3 at the two ends, and therefore limiting can be achieved at the two ends.
According to the side hung door limiting device, the cabinet door drives the limiting pin 4 to move, the limiting pin 4 drives the limiting component 1 to rotate around the rotating shaft in the moving process, the limiting pin 4 can be respectively sunk into the limiting grooves 3 at two ends in the closing state and the maximum opening state of the cabinet door, the limiting grooves 3 exert blocking acting force on the limiting pin 4, and the cabinet door can be stably limited in two different states. When the limiting pin 4 is positioned in the limiting groove 3, the blocking force of the limiting groove 3 to the limiting pin 4 is far greater than the friction resistance of the limiting pin 4 moving in the arc-shaped groove 2, and only when the cabinet door is rotated by artificial external force, the limiting pin 4 can be moved into the arc-shaped groove 2 from the limiting groove 3 to easily rotate the cabinet door.
The vertical hinged door limiting device can change the force required by the limiting pin 4 moving out of the limiting groove 3 by replacing elastic pieces with different elastic coefficients or changing the width of the limiting groove 3, thereby adjusting the stability during limiting and locking.
On the basis of the scheme, the elastic part is the extension spring 5, as shown in fig. 2, one end of the extension spring 5 is connected to the end part of the limiting part, the other end of the extension spring is connected to one side of the cabinet body close to the arc center of the arc-shaped groove 2, and when the cabinet door rotates along the anticlockwise state, the limiting pin 4 moves from the left side to the right side of the arc-shaped groove 2 until the limiting pin is clamped into the limiting groove 3 on the right side; in both the fully opened and the fully closed states, the tension spring 5 applies an elastic force to the restricting member so that it has a tendency to rotate, thereby enabling the restricting pin 4 to be effectively caught in the restricting groove 3.
Besides the tension spring, a torsion spring may be disposed at the rotation shaft of the position limiting component, which also enables the position limiting component 1 to have a tendency to rotate, and these specific embodiments are all included in the protection scope of the present invention.
Preferably, the plastic shells for reducing friction and noise are respectively wrapped on the edges of the two sides of the arc-shaped groove 2, the limiting pin 4 and the limiting part 1 are made of metal materials, and the limiting pin 4 is in direct contact with the plastic shells, so that the friction resistance of the limiting pin 4 in the moving process can be reduced, the noise is reduced, and the use is more quiet.
Preferably, the invention is sleeved with a bearing at the periphery of the limit pin 4, and the outer ring of the bearing is contacted with the plastic shell at the edge of the arc-shaped groove 2, so that the noise can be reduced.
The limiting pin 4 is a bolt and a nut which are matched with each other, and the friction force between the limiting pin and the arc-shaped groove 2 can be adjusted; the bolt runs through whole arc wall 2 in the structure shown in fig. 2, and the bolt head and the nut are pressed on the both sides surface of arc wall 2 from both sides respectively, can adjust the degree of tightening of nut and adjust the degree of compressing tightly to arc wall 2, and then change frictional force size, adjust the friction damping of spacer pin 4 motion in arc wall 2.
The invention also provides a cabinet which comprises the vertical hinged door limiting device and can realize the same cabinet door limiting effect. For other parts of the cabinet, reference is made to the prior art, and the present invention is not described herein again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
