[0031] like Figures 1 to 7 As shown, the utility model provides a gun cabinet with hidden hinges, the gun cabinet comprising a cabinet assembly 10, a cabinet door assembly 20, and a hinge device 30 connecting the cabinet assembly 10 and the cabinet door assembly 20, the cabinet door assembly 20 is connected to the cabinet assembly 10 through the hinge device 30, so as to realize the rotatable connection of the cabinet door assembly 20. The cabinet assembly 10 is provided with a receiving space, and an instrument mounting rack is installed in the cabinet assembly 10.

[0032] The cabinet assembly 10 is provided with a cabinet door groove 11, and the cabinet door groove 11 is a groove structure located at the opening of the cabinet assembly 10. When the cabinet door assembly 20 closes the opening of the cabinet assembly 10, the cabinet door assembly 20 abuts against the cabinet door groove 11, so that at least part of the cabinet door assembly 20 abuts against the cabinet door groove 11, and the edges of the cabinet door assembly 20 and the cabinet assembly 10 are flush to improve the flatness and aesthetics. The hinge device 30 connects the cabinet assembly 10 and the cabinet door assembly 20 respectively, wherein the hinge device 30 includes a first mounting seat 31, a second mounting seat 32, at least one group of first hinged assemblies 33 and at least one group of second hinged assemblies 34 that are hingedly connected, and the first hinged assemblies 33 and the second hinged assemblies 34 are hingedly connected to form a rotatable structure.

The first mounting seat 31 is embedded and installed in the first mounting groove 14, and the second mounting seat 32 is embedded and installed in the second mounting groove 21, so that the first mounting seat 31 is hidden in the cabinet assembly 10, and the second mounting seat 32 is hidden in the cabinet door assembly 20.

[0034] One end of the first hinge assembly 33 is hingedly connected to the first mounting seat 31, and the other end of the first hinge assembly 33 is slidably connected to the second mounting seat 32. One end of the second hinge assembly 34 is hingedly connected to the second mounting seat 32, and the other end of the second hinge assembly 34 is slidably connected to the first mounting seat 31. The first hinge assembly 33 and the second hinge assembly 34 intersect and rotate, and the hinge point is located between the first mounting seat 31 and the second mounting seat 32. The end of the first hinge assembly 33 is slidably connected to the second mounting seat 32 to balance the movement trajectory of the first hinge assembly 33, and also to improve the connection strength of the first hinge assembly 33 to the first mounting seat 31 and the second mounting seat 32. Similarly, the end of the second hinge assembly 34 is slidably connected to the first mounting seat 31, thereby forming a symmetrical sliding structure.

[0035] The cabinet door assembly 20 rotates to open and close the opening of the cabinet body assembly 10, and the first hinge assembly 33 and the second hinge assembly 34 rotate relatively, and at least part of the first hinge assembly 33 and the second hinge assembly 34 telescopically slide along the first mounting groove 14 and the second mounting groove 21. When the cabinet door assembly 20 is closed to the cabinet body assembly 10, the cabinet door assembly 20 rotates to abut against the cabinet door groove 11 of the cabinet body assembly 10. The first hinge assembly 33 and the second hinge assembly 34 can rotate relatively, and the ends of the first hinge assembly 33 and the second hinge assembly 34 slide into the first mounting groove 14 and the second mounting groove 21 correspondingly. The hinge device 30 is hidden in the cabinet body assembly 10 and the cabinet door assembly 20, thereby preventing the hinge device 30 from being directly damaged and improving safety. The hinge device 30 is provided with a first hinge component 33 and a second hinge component 34 which are hingedly connected, and is slidably matched with the first mounting seat 31 and the second mounting seat 32 to achieve multiple supports and improve impact resistance, thereby improving the rotation stability of the cabinet door assembly 20. The hidden setting of the hinge device 30 can also improve the overall aesthetics and surface smoothness of the gun cabinet.

[0036] like Figures 3 to 7 As shown, the first hinge assembly 33 and the second hinge assembly 34 have the same structure and working principle. In the direction of the rotation axis 36 of the hinge device 30, the first hinge assembly 33 and the second hinge assembly 34 are alternately distributed to form an axial misalignment. The first hinge assembly 33 is taken as an example for exemplary description, and the second hinge assembly 34 can be understood by reference.

The first mounting seat 31 and the second mounting seat 32 are basically the same in structure and principle, and are staggered at the connection position of the first hinge assembly 33 and the second hinge assembly 34.

[0043] The first mounting seat 31 includes a seat body 313, a sliding portion 311 disposed on the side of the seat body 313, and a hinge portion 314 located at one end of the seat body 313. The first hinge assembly 33 is hingedly connected to the hinge portion 314, and the second hinge assembly 34 is slidably connected to the sliding portion 311. The hinge portion 314 is provided with a hinge groove, and the hinge arm 333 extends into the hinge groove. The rotation shaft 36 connects the hinge arm 333 and the hinge portion 314 to form a rotation structure.

[0044] The sliding part 311 is located at one side of the seat part 313 to form a sliding structure. Optionally, the sliding part 311 is a sliding hole, and the second hinge assembly 34 is provided with a sliding column, which is inserted and slid in the sliding hole. Optionally, the sliding part 311 is a sliding groove, and the second hinge assembly 34 is provided with a slider, which is inserted and slid in the sliding groove. Optionally, the sliding part 311 is a T-slot, and the second hinge assembly 34 is provided with a sliding shaft 37, and both ends of the sliding shaft 37 are limited to the sliding part 311 to form a sliding structure.

[0045] In a specific embodiment, the sliding portion 311 includes a central sliding groove and guide grooves located on the groove walls on opposite sides of the central sliding groove, the second hinge assembly 34 extends into the central sliding groove, and both ends of the sliding shaft 37 of the second hinge assembly 34 are limited in the guide grooves. The central sliding groove and the guide groove form a structure similar to a T-shaped groove, the second hinge assembly 34 and the sliding shaft 37 at the end form a T-shaped structure, and the sliding shaft 37 is slidably limited in the guide groove, thereby realizing a sliding anti-slip structure.

[0046] like Figures 1 to 5 As shown, in one embodiment, flange bosses 312 are provided on both sides of the first mounting seat 31, and the flange bosses 312 are used to connect the cabinet assembly 10. The flange bosses 312 are distributed on both sides of the first mounting seat 31, so as to be locked with the two side walls of the opening of the first mounting groove 14 by fasteners, so that the seat body 313 extends into the first mounting groove 14, and the sliding portion 311 slides in the first mounting groove 14. Preferably, the flange bosses 312 are symmetrically distributed on both sides of the seat body 313 to form an assembly structure. Further, the flange bosses 312 are distributed at the ends of the seat body 313.

[0047] In one embodiment, the cabinet assembly 10 includes a cabinet plate 13 and an inner support frame 12, the first mounting groove 14 is a notch groove set in the inner support frame 12, the cabinet plate 13 covers the surface of the inner support frame 12, and there is a movable gap between the cabinet plate 13 and the cabinet door assembly 20. The inner support frame 12 is a rigid structure to provide support for the cabinet assembly 10 to prevent structural damage and heavy impact damage. The cabinet plate 13 covers the surface of the inner support frame 12, thereby concealing the opening area of ​​the inner support frame 12 and maintaining the rotation flexibility of the hinge device.

[0048] Further, the cabinet door assembly 20 includes a cabinet door plate 23 and a cabinet door frame 22, the second installation groove 21 is a groove recessed from the side of the cabinet door frame 22, and the cabinet door plate 23 covers the surface of the cabinet door frame 22.
