Description

M248875 3. Creation description (1) [Technical field to which the new type belongs] The new type is a composite design of a hinge and a special element, which has a conventional hinge device that saves effort with the prior art, including: an upper part, a rotary base, Locked between a fixed seat and a rotary seat on a door panel for connecting and fixedly disposed between the fixed seat and the rotary seat, and a buffer member provided on the fixed seat and the connection; when the door panel is opened to a door opening position, the positioning member is When the door is closed and the positioning member is driven, the buffering member is set to release the restoring force of the buffering member, and then the board is moved to a door closing position. Although the conventional hinge device provides the restoring force to reset the positioning member, during the resetting process, the restoring force of the cushioning member is also released instantaneously, causing the door finger and the door plate to collide with the door frame, which will cause the situation. It is easy to cause 0 and other known hinges on door panels and door frames. For details, see Zhongfu. Its structure is roughly the same as the above. It is a fixed air-hydraulic cylinder. The door panel is opened. Pneumatic hinge with elastic cushioning effect. ~ Solid; ~ Between the seat and the upper palate. When the rotating parts abut the board, the positioning pieces of the positioning pieces are locked to a door frame connecting piece and installed on the fixed rotating seat; a positioning piece is installed on the opposite side of the connecting piece; the rotating seat is far away from the fixing seat, so that 7 members 'Make the buffering part to make' The state of the rotating seat close to the fixed seat is lifted, and the release piece is reset, and when the door is closed, the door panel is brought to the closed position by the buffering member, but suddenly comes off in the top state The solution makes the buffer plate close quickly, which can easily cause a loud sound of the crushing hand, which will cause damage in long-term use. Republic of China Patent Bulletin No. 509270 The above-mentioned buffer member is a post-mounted 疋 bit that will drive the pneumatic cylinder

M248875 Description of creation (2) = Cylinder = Retracted to the air-hydraulic cylinder to provide positioning force. When the door is closed, the return and re-cylinder shaft set by ^ is extended, and the plate is driven by the mountain L. Slowly close it to make the soil come out of the emulsification cylinder. 『Κ However, it is possible to improve the shortcomings of the fast closing door panel mentioned above from the second and the ancient. The locking mr # force of the door panel: Under long-term application of force, the rotating seat and the [new inner ξ] door panel are damaged. Existing == ;; The purpose is to solve the above-mentioned shortcomings, to avoid the missing closure, resulting in finger injury Dongda: ^ Off: when the '& pieces will not be quickly I · large and continuous and need not be applied when opening the door Yuan, ϋDescription; r, the new type of pneumatic hinge system provides-reset single elastic 3 = pieces, an abutment piece and a pressure rainbow; use the above-mentioned pieces to provide the restoring force of the abutment piece reset; and the above-mentioned air pressure The cylinder has a retractable, mortal shaft'-cylinder shaft-terminus provided on the above-mentioned abutment piece, and in addition, the outer wall of which is adjusted to a thickness of two cylinder shafts extending from the center The pressure of the random pressure cylinder is smaller than that of the pressure cylinder. When the panel is opened to the door opening position, the abutment member will stop the above-mentioned elastic element. At this time, the m pieces will generate a restoring force to reset the abutment member, and the abutment member will drive the cylinder shaft into the pneumatic cylinder; When closing the board

Factory: r reset, at this time, the abutment piece will drive the 乱 cylinder, so that the cylinder produces a cushioning force that can slowly reset the abutment piece, by I

Page 6 M248875 4. Creation instructions (3) · The restoring force and buffering force mentioned above allow the board to be slowly moved to the door closing position to avoid the restoring force generated by the elastic member to quickly reset the board.
