[0005] A concealed hinge for an experimental bench cabinet includes a first blade. The first blade includes a first screw hole plate and a first hinge. An embedding platform is provided between the first screw hole plate and the first hinge. The embedding platform is used to embed into a groove with a corresponding size in the cabinet body, so that the first screw hole plate is located inside the cabinet body.
[0006] Furthermore, it further includes a second blade. The second blade includes a second screw hole plate and a second hinge hinged with the first hinge. A cabinet door fitting surface for installing on the side edge of the cabinet door is provided on the second screw hole plate.
[0007] Furthermore, a first partition is provided between the first hinge and the embedding platform, so that a fitting embedding area is formed between the side surface of the embedding platform between the first hinge and the first screw hole plate.
[0008] Furthermore, the lengths of the first screw hole plate and the first partition in the cross-section are both greater than the length of the embedding platform in the cross-section, so that the embedding area is in a "匚" shape.
[0009] Furthermore, a second partition is provided between the second hinge and the second screw hole plate. When the cabinet door fitting surface fits on the side edge of the cabinet door, the side of the second partition close to the second screw hole plate fits on the side of the cabinet door facing the outside.
[0010] Furthermore, a first abutting edge is provided on the first partition, and a second abutting edge is provided on the second partition. When the cabinet door is closed, the second hinge rotates around the hinge axis to drive the second partition to flip, so that the second abutting edge abuts against the first abutting edge, so that the second screw hole plate flips and moves to the inner side of the cabinet.
[0011] Furthermore, the first hinge and the first partition are both made of PP plastic material, and the second hinge and the second partition are both made of PP plastic material.
[0012] Furthermore, it also includes a connecting shaft that passes through the first hinge and the second hinge, and the connecting shaft is made of PP plastic.

[0021] The following specific implementation contents provide a variety of different embodiments or examples for implementing the utility model. Of course, these are only embodiments or examples and are not intended to be limiting. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0023] like Figures 1 to 3 The hidden hinge of a laboratory bench cabinet shown in the figure comprises a first blade 1, wherein the first blade 1 comprises a first screw hole plate 11 and a first hinge 12, wherein an embedding platform 13 is provided between the first screw hole plate 11 and the first hinge 12, wherein the embedding platform 13 is used to embed into a groove of a corresponding size of a cabinet, so that the first screw hole plate 11 is located on the inner side of the cabinet. In the hidden hinge of the laboratory bench in this embodiment, a structural design of adding an embedding platform 13 is adopted on the first blade 1, so that when the hinge is installed, the embedding platform 13 can be embedded into the groove pre-opened in the cabinet, thereby hiding the first screw hole plate 11 on the inner side of the cabinet, and screws are driven into the inner side of the cabinet through the screw holes on the first screw hole plate 11, so as to achieve the effect of hiding the first screw hole plate 11 and the connecting screws in the cabinet of the laboratory bench, which can significantly reduce various rust, deformation, corrosion and aging of the connection part between the hinge and the cabinet, and improve the aesthetics of the hinge installed on the laboratory bench.
[0024] The concealed hinge of the laboratory bench cabinet of this embodiment further includes a second blade 2, which includes a second screw hole plate 21 and a second hinge 22 hingedly connected to the first hinge 12, and the second screw hole plate 21 is provided with a cabinet door fitting surface 211 for installation on the side of the cabinet door. After the second screw hole plate 21 is fixed to the side of the cabinet door by screws, when the cabinet door is closed, the second screw hole plate 21 flips and moves and is hidden in the gap between the side of the cabinet door and the cabinet body, further reducing various rust, deformation, corrosion, and aging of the connection part between the hinge and the cabinet body, and further improving the aesthetics of the hinge installed on the laboratory bench.
[0025] A first partition plate 14 is provided between the first hinge 12 and the embedding table 13, so that a fitting embedding area 15 is formed on the side surface of the embedding table 13 between the first hinge 12 and the first screw hole plate 11. Preferably, the lengths of the first screw hole plate 11 and the first partition plate 14 in the cross-section are both greater than the length of the embedding table 13 in the cross-section, so that the embedding area 15 is in a "C" shape. After the embedding table 13 is embedded into the cabinet groove, the cabinet is completely clamped into the fitting embedding area 15. At this time, the side of the first partition plate 14 close to the embedding table 13 presses against the side of the cabinet facing the outside world, and the side of the first screw hole plate 11 close to the embedding table 13 presses against the side of the cabinet facing its interior, making the fitting between the embedding table 13 and the cabinet more airtight.
[0026] A second partition plate 23 is provided between the second hinge 22 and the second screw hole plate 21. When the cabinet door fitting surface 211 fits against the side of the cabinet door, the side of the second partition plate 23 close to the second screw hole plate 21 fits against the side of the cabinet door facing the outside world, making the connection and fixation between the second screw hole plate 21 and the cabinet door more airtight.
[0027] A first abutting edge 141 is provided on the first partition plate 14, and a second abutting edge 231 is provided on the second partition plate 23. When the cabinet door is closed, the second hinge 22 rotates around the hinge axis to drive the second partition plate 23 to flip, so that the second abutting edge 231 abuts against the first abutting edge 141, so that the second screw hole plate 21 flips and moves to the inner side of the cabinet. The settings of the first abutting edge 141 and the second abutting edge 231 facilitate restricting the relative rotation angle between the first partition plate 14 and the second partition plate 23, thus ensuring that the cabinet door will not shift inward when closed.
[0028] Preferably in this example, the first hinge 12 and the first partition plate 14 are both made of PP plastic material, the second hinge 22 and the second partition plate 23 are both made of PP plastic material; the invisible hinge of the experimental bench cabinet in this embodiment further includes a connecting shaft 3 connecting the first hinge 12 and the second hinge 22, and the connecting shaft 3 is made of PP plastic material; secondly, the first screw hole plate 11, the second screw hole plate 21 and the embedding table 13 are all made of PP plastic material. The first hinge 12, the first partition plate 14, the second hinge 22, the second partition plate 23, the connecting shaft 3, the first screw hole plate 11, the second screw hole plate 21, and the embedding table 13 in this example are all made of PP plastic material, which can give full play to the greatest advantages of the PP plastic material in the laboratory environment and have properties such as waterproof, acid-proof, and alkali-proof that metal materials do not have.
[0029] Preferably, the edge of the first screw hole plate 11 away from the embedding table 13 is arc-shaped, which can prevent cutting hands and is convenient for installation.
[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
