Detailed implementation manner

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-7 , the present invention discloses an up-turning and plugging door structure, including an up-turning door buffer and boost mechanism 3. The up-turning door buffer and boost mechanism 3 includes a fixed sheet metal 31. A guide rail 32 is provided at the top of the fixed sheet metal 31. A door panel guide wheel 33 is movably provided inside the guide rail 32. A boost arm 34 is movably provided on one side of the fixed sheet metal 31. One end of the boost arm 34 is movably provided with a gas spring or a rebound damper 35. The end of the gas spring or the rebound damper 35 away from the boost arm 34 is movably connected to one side of the fixed sheet metal 31.

[0027] Specifically, a door panel mounting angle bracket 331 is provided on one side of the door panel guide wheel 33. A sliding wheel 36 is movably provided inside one end of the boost arm 34. One end of the boost arm 34 abuts against the door panel 2 through the sliding wheel 36, which can boost the door panel 2 when it is turned up, and at the same time avoid scratching one side of the door panel 2.

[0028] Specifically, a plug 37 is provided at one end of the guide rail 32, and a load-bearing wheel 371 is movably provided on one side of the plug 37. The top of the load-bearing wheel 371 protrudes to the top of the guide rail 32. Refer to Figures 6-7 , the load-bearing wheel 371 is used to support the door panel 2 in the stored state. This design method can avoid direct friction between the door panel 2 and the end of the guide rail 32, and at the same time make the pulling of the door panel 2 smoother.

[0029] Specifically, an anti-collision limit member 38 is provided at the end of the guide rail 32 away from the plug 37. One end of the anti-collision limit member 38 extends to the top of the guide rail 32. The anti-collision limit member 38 is provided to prevent the door panel 2 from hitting the back panel of the cabinet body 1 when it is stored.

[0030] Specifically, one side of the fixed sheet metal 31 is connected with a boosting spring 39 through a hanging shaft 311. A positioning shaft 341 which is clamped with one end of the boosting spring 39 is arranged inside the boosting arm 34. The arrangement of the boosting spring 39 can assist the gas spring or the rebound damper 35 to pull the boosting arm 34 to turn over.

[0031] Specifically, a first positioning post 312 located below the hanging shaft 311 is arranged on one side of the fixed sheet metal 31. The boosting arm 34 is hinged to one side of the fixed sheet metal 31 through the first positioning post 312. A second positioning post 313 located obliquely below the anti-collision limiting member 38 is arranged on one side of the fixed sheet metal 31. One end of the gas spring or the rebound damper 35 is hinged to one side of the fixed sheet metal 31 through the second positioning post 313. The first positioning post 312 and the second positioning post 313 are respectively used for installing the boosting arm 34 and the gas spring or the rebound damper 35.

[0032] Specifically, both the fixed sheet metal 31 and the guide rail 32 are inclined. Refer to Figure 6 , the inclined fixed sheet metal 31 and guide rail 32 make the door panel 2 in an inclined state when in the storage state, so that it will not slide out suddenly, and it is safer to use.

[0033] Specifically, it further includes a cabinet body 1 and a door panel 2. The fixed sheet metal 31 is installed on both sides of the inner wall of the cabinet body 1. One side of the top of the door panel 2 is fixedly connected with one side of a door panel mounting angle code 331. The surface of the sliding wheel 36 is movably connected with one side of the door panel 2. Closing limiting members 11 are arranged on both sides of the inner wall of the cabinet body 1. The closing limiting members 11 are in contact with one side of the door panel 2. The closing limiting members 11 are used for limiting the door panel 2 after it turns down in place. After the door panel 2 turns down in place, the handle bar 21 is completely immersed in the cabinet body 1, and the appearance is more beautiful.

[0034] Specifically, a handle bar 21 is arranged at the bottom of the door panel 2. Refer to Figure 1 and 4 , books are placed both inside the cabinet body 1 and on one side of the door panel 2, which facilitates the display of books, convenient for display and sale. The handle bar 21 can not only hold the books on one side of the door panel 2, but also the user can pull the door panel 2 through the handle bar 21, and when the door panel 2 is turned up, it is not necessary to remove the books on the door panel 2, and the operation and use are more convenient.

[0035] In summary, for this upward-opening plug door structure, the door panel 2 is in an upward-opening form and can be stored inside the cabinet body 1 without occupying external space, and the installation difficulty is greatly reduced. The flip door buffer boosting mechanism 3 can boost the door panel 2 when it is turned up and buffer when it is turned down, making it more labor-saving for the user to turn up and with a uniform speed when turning down. Books can be placed both inside the cabinet body 1 and on the door panel 2, and it is more convenient to use.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
