In the hidden upturning support device 100 of the embodiment of the present utility model, the outer casing 1 adopts an aluminum profile; the inner shell 2 comprises an outer ferrous layer 23 and an inner plastic layer 24.
The utility model relates to an upturning door locker, which comprises a locker body 200, a locker door 300 hinged with the locker body, and a hidden upturning supporting device 100, wherein a shell 1 of the hidden upturning supporting device is fixedly arranged at the front edge of a side plate of the locker body 200, and a connecting rod mechanism 6 of the hidden upturning supporting device is connected with the locker door 300; wherein, the storage opening 101 is located at the front position of the outer casing 1, the back of the outer casing 1 is provided with a plugging strip 14 along the length direction thereof, and the front edge of the side plate of the cabinet 200 is provided with a plugging slot 201, and the plugging strip 14 is plugged into the plugging slot 201 and fixed by glue, so that the hidden upturning support device 100 and the cabinet 200 are fixed.
The hidden upturning support device with adjustable force and the upturning door locker adopting the hidden upturning support device have the advantages that:
1) The hidden upturning support device is arranged at the front edge of the side plate of the cabinet body, so that the space in the cabinet is not occupied, the width of the cabinet body is not increased, the installation size and the household layout are not affected basically, and the attractive appearance of the cabinet can be maintained.
2) The hidden upturning support device is arranged at the front edge of the side plate of the cabinet body, and the observation hole, the operation hole and the like are positioned at the front position, so that the adjustment operation can be very easy, and the operation effect can be very easy to observe. If the upturning support device is installed in the cabinet, a plurality of inconveniences are brought: for example, the head needs to be stretched into the cabinet for observation and operation, so that the cabinet is inconvenient, the space in the cabinet is narrow and dark, the difficulty is further improved, the risk of smashing the head under the cabinet door is caused by the error adjustment, and the cabinet is very inconvenient; for example, if the spring strength is required to be improved due to long-term use and aging of the spring, the articles in the cabinet need to be taken out first, and after adjustment, the articles are put back into the cabinet, which is very troublesome.
3) The hidden upturning support device is very simple to install and can be adhered by glue.
4) In order to be suitable for being mounted on the front edge of the side plate of the cabinet body and being suitable for the mounting mode of glue cementation, the device needs to be designed to be light enough; however, the problem of insufficient spring moment can be caused, so that the technical effect of increasing the included angle between the supporting arm and the acting force of the spring and further increasing the spring moment is realized by arranging the kidney-shaped hole and the fixed shaft on the first connecting rod and adding the push rod at the top end of the supporting arm; meanwhile, as the waist-shaped hole and the fixed shaft are arranged on the first connecting rod, the weight can be reduced because the waist-shaped hole is of a hollowed-out structure, the size of the push rod is not required to be large, and the push rod can be abutted with the fixed shaft, so that the whole volume and the weight of the hidden upturning supporting device are basically unaffected.
The hidden upturning support device with adjustable force and the upturning door locker adopting the hidden upturning support device provided by the embodiment of the utility model have the following working principle:
1) According to the upturned door locker disclosed by the embodiment of the utility model, when the cabinet door is unfolded in a range of 0-30 degrees, the cabinet door is in a state capable of being automatically buffered and closed, and when the cabinet door is unfolded in a range of 30-90 degrees, the cabinet door is in a state capable of being hovered at will; when the cabinet door is unfolded to 45 degrees, the push rod and the fixing column are abutted, when the cabinet door is gradually unfolded to 90 degrees from 45 degrees, the push rod is gradually moved to the other end from one end in the kidney-shaped hole, and the spring moment is gradually increased in the process.
2) When the cabinet door is opened, the cabinet door is directly pulled upwards to 30-90 degrees; when the cabinet door is closed, the cabinet door is lowered to within 30 degrees, and then the cabinet door can be automatically buffered and closed.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
