DETAILED DESCRIPTION

[0026] Example 1

[0027] See also Figures 1 to 6As shown, a wall cabinet and a bottom-folding storage cabinet of the utility model comprises a cabinet body 1 and a cabinet door 2 matched with the front end opening of the cabinet body 1, and a handle is provided at the cabinet door to facilitate opening and closing of the cabinet door. Of course, if the upper end of the cabinet door is designed to be arc-shaped or other conventional structures in the field that are easy to operate by hand to open and close the cabinet door are designed, these are equivalent alternatives that can be easily thought of by technicians in this field. The two ends of the cabinet door 2 are connected to the cabinet body 1 through an opening and closing mechanism 3, and the left and right sides of the cabinet body 1 are respectively provided with a base 4, and a mounting plate 5 is provided on the base 4. A plurality of positioning columns 6 are distributed on the base 4, and a first positioning hole 5a corresponding to each positioning column 6 is provided on the mounting plate 5.

[0028] A connection hole 6a is axially arranged at the free end of the positioning column 6, and a screw passes through the first positioning hole 5a and is threadedly connected to the connection hole 6a, and the opening and closing mechanism 3 is connected between the mounting plate 5 and the cabinet door 2. In this embodiment, when the first positioning hole is a columnar through hole and is adapted to the positioning column, the outer diameter of the screw nut is larger than the inner diameter of the first positioning hole; of course, as a person skilled in the art, the first positioning hole can also be designed as a stepped hole, which is an easily conceivable equivalent alternative.

[0029] With this structure, the structures for installing the opening and closing mechanism at the left and right ends of the cabinet can be made of plastic, and the metal mounting plate can bear the force applied to the mounting position by the opening and closing mechanism. This can greatly reduce the weight of the product and the processing cost.

[0030] Preferably, the cabinet 1 includes quadrilateral mounting cavities 1a located on the left and right sides, and the two mounting cavities 1a are connected by four cross beams 1b to form a cabinet frame; the base 4 is integrally formed in the corresponding mounting cavity 1a. When forming the cabinet, it is sufficient to install the corresponding partition between two adjacent cross beams. The operation is very convenient, and the material can be selected according to the specific needs.

[0031] In this embodiment, the opening and closing mechanism 3 includes a connecting rod 3a hinged on the mounting plate 5, and the end of the connecting rod 3a close to the mounting plate 5 is connected to a linkage bar 3b, and the free end of the linkage bar 3b is hinged to a gas spring 3c, and the free end of the gas spring 3c is hinged to the mounting plate 5; a limiting structure for limiting the rotation angle of the connecting rod 3a is provided on the mounting plate 5.

[0032] When the cabinet door 2 is in a closed state, the gas spring 3c is in an extended state so that the cabinet door 2 is close to the opening of the cabinet body 1; when the cabinet door 2 is in an open state, the connecting rod 3a or the linkage bar 3b or the gas spring 3c is in contact with the limiting structure, and at the same time, the angle α formed by the connecting line segment s from the center point of the hinge point of the connecting rod 3a and the mounting plate 5 to the center point of the hinge point of the linkage bar 3b and the gas spring 3c and the central axis of the gas spring 3c is 178-210°.

[0033] It should be noted that the angle α is the angle formed by the connection line segment s and the central axis of the gas spring and gradually increases. As a person skilled in the art, based on the concept and drawings of the utility model, it can be clearly known that when the angle α is 180°, the gas spring is at the upper limit of extension, and the cabinet door is preferably in a horizontal state at this time; and when the angle is at 178°, the cabinet door is about to open to a horizontal state, and the value is set to 178, mainly considering the resistance generated by the friction at the product connection caused by the processing technology, so that the gas spring will not automatically retract. Correspondingly, based on this concept, if some related friction-increasing or limiting structures are designed, the value can be smaller in theory. Similarly, when the value is 210, the cabinet door continues to flip backward to a certain tilt angle after opening to a horizontal state. At this time, the gas spring will theoretically retract, but because of the setting of the blocking column, the cabinet door can be stably maintained in a corresponding tilt state under the action of the gas spring retraction force and the positioning of the blocking column. For this concept, the corresponding tilt angle can be specifically selected by those skilled in the art, which does not require creative labor.

[0034] Based on the above concept, the utility model can also limit another angle that matches the angle α to be 360°, and its value also needs to be based on the above design concept. This is also an equivalent alternative solution that can be easily thought of by technical personnel in this field.

[0035] In this embodiment, the linkage bar 3b is composed of a clearance section 3d connected vertically or obliquely to the connecting rod 3a and a connecting section 3e integrally formed at the free end of the clearance section 3d and hinged to the gas spring 3c; the clearance section 3d and the connecting section 3e cooperate to form an L-shape or a V-shape. The purpose of the clearance section is to form gaps of different widths between the driving connecting rod and the connecting section and the inner wall of the accommodating cavity, so that the driving connecting rod will not hit the limit column when rotating, but the connecting section can hit it.

[0036] Preferably, the limiting structure is a limiting column 7 arranged on the mounting plate 5 at the lower side of the hinged part of the gas spring 3c and the linkage strip 3b, and a buffer rubber sleeve is provided on the outer sleeve of the limiting column 7; when the cabinet door 2 is opened, the gas spring 3c contracts, and when the hinged part of the gas spring 3c and the linkage strip 3b contacts the limiting column 7, the cabinet door 2 is in a fully open state and the hinge point of the connecting rod 3a and the accommodating cavity and the center point of the hinge point at both ends of the gas spring 3c are located on the same straight line. In this embodiment, the linkage strip is used to contact the limiting column. Of course, it is also possible to use the gas spring to contact the limiting column, but it may reduce the service life of the gas spring, and relevant protection design needs to be performed on the gas spring. At the same time, based on the above-mentioned conception about the angle, when the linkage strip contacts the limiting column, the angle α can also be greater than 180° to make the cabinet door in an inclined state.

[0037] Further preferably, the base 4 is composed of annular ribs 4a and reinforcing ribs 4b interlaced in the annular ribs 4a in a horizontal and vertical manner; the annular ribs 4a and the reinforcing ribs 4b have the same height and cooperate with each other to form a support surface. In this embodiment, the base and the mounting cavity are integrally injection molded to save processing costs.

[0038] The positioning posts 6 are located at the intersection of the transverse and longitudinal reinforcing ribs 4b and are higher than the reinforcing ribs 4b. When the mounting plate 5 contacts the supporting surface, each positioning post 6 extends into the corresponding first positioning hole 5a. This structure can improve the strength and stability of the positioning posts.

[0039] In this embodiment, in order to improve the strength and stability of the mounting plate, a reinforcing column 8 is provided in the middle of the annular rib 4a, and the reinforcing column 8 is located at the intersection of the transverse and longitudinal reinforcing ribs 4b and is higher than the reinforcing ribs 4b; a second positioning hole 5b corresponding to the reinforcing column 8 is provided on the mounting plate 5. The reinforcing column is designed to be larger than the positioning column, which can effectively ensure the strength of the mounting plate.

[0040] Example 2

[0041] See also Figure 7 and Figure 8 As shown, a wall cabinet flip-down storage cabinet of the utility model has a structure that is basically the same as that of Example 1, except that a positioning cover 9 is provided on the periphery of the mounting plate 5, and the positioning cover 9 is wrapped around the periphery of the base 4; a third positioning hole 9a corresponding to the positioning column 6 is provided on the positioning cover 9, and a screw passes through the third positioning hole 9a and the first positioning hole 5a in sequence and is threadedly connected with the connecting hole 6a. Compared with Example 1, the mounting plate can be further reinforced from all sides, and the structure will be more stable and have higher strength.

[0042] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
