Description

Technical Field

[0001] The utility model relates to the technical field of drawing storage, in particular to an automatic flipping drawing fixing device. Background Art

[0002] In some work scenarios, drawings are stored in drawers, and the drawers need to be frequently pulled out to access the drawings. When placed in the drawers, the drawings may swell and touch the edges of the drawers, which may cause the drawings to be squeezed and damaged when the drawers are pulled out. Utility Model Content

[0003] In order to solve the problem that in certain work scenarios, drawers need to be frequently pulled out to store and retrieve items, which may cause damage to drawings in the drawers, the utility model provides an automatically flipping drawing fixing device.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An automatic flipping drawing fixing device comprises a fixing plate and a drawer, wherein sliding grooves are provided on both sides of the drawer and are slidably connected to sliding shafts located on the fixing plates on both sides thereof, and pulleys are provided at the ends of the sliding shafts away from the fixing plates; a flipping splint is rotatably connected to the inside of the drawer via a hinge shaft, and a torsion spring is provided on the hinge shaft for automatically resetting the flipping splint.

[0006] Preferably, the flipping splint is evenly distributed with a plurality of small holes for reducing the weight of the flipping splint to facilitate flipping.

[0007] Preferably, the edges of the flip clamp are rounded to prevent it from causing damage to the drawings or administrators.

[0008] Preferably, the pulley is rotatably connected to the pulley shaft via a bearing, and a concave track is provided on the flip clamp at a position corresponding to the pulley.

[0009] Compared with the prior art, the utility model has the following beneficial effects: when the drawer is pulled out, the flip clamp automatically flips over and no longer clamps the drawings, and when the drawer is pushed in, the flip clamp automatically clamps the drawings, effectively preventing damage to the drawings when the drawer is pulled out, and improving the safety and service life of the drawings.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figures 1 to 3 As shown, the embodiment of the utility model includes a fixed plate 1 and a drawer 4, and slide grooves 5 are opened on both sides of the drawer 4, and are slidably connected with the sliding shafts 2 located on the fixed plates 1 on both sides thereof, and pulleys 3 are provided at the ends of the sliding shafts 2 away from the fixed plates 1; the inside of the drawer 4 is rotatably connected with a flip splint 8 through a hinge shaft 6, and a torsion spring 7 is provided on the hinge shaft 6 for automatically resetting the flip splint 8.

[0018] Preferably, the flip splint 8 is evenly distributed with a number of small holes for reducing the weight of the flip splint 8 for easy flipping; the edges of the flip splint 8 are rounded to prevent it from causing damage to the drawings or the administrator; the pulley 3 is rotatably connected to the slide shaft 2 through a bearing, and a concave track is provided on the flip splint 8 at the position corresponding to the pulley 3.

[0019] like Figure 4 As shown, the drawer is in a closed state, at which time the flip plate 8 cooperates with the bottom of the drawer 4 to clamp the drawing. When the drawer 4 is pulled out, the flip plate 8 automatically flips upward under the action of the torsion spring 7. When the pulley 3 reaches the limit position of the slide slot 5, the pulley 3 limits the flip plate 8 to maintain a fixed angle, as shown in FIG. Figure 1 As shown, when the drawing is put in, as the drawer 4 is pushed in, the pulley 3 moves toward the front end of the slide slot 5 and presses down the flip clamp 8, and the flip clamp 8 fixes the drawing to prevent the drawing from being damaged when the edge is lifted and pulled out. When the drawer 4 is pulled out, the flip clamp 8 automatically flips over and no longer clamps the drawing, and automatically clamps the drawing when pushed in.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
