Description

Technical Field

[0001] The present application relates to the technical field of packaging and storage, and more specifically to a utility knife blade box. Background Art

[0002] A utility knife is a handheld small knife for arts and crafts, which includes a handle and a blade slidably mounted on the handle. The handle and the blade adopt a detachable push-pull structure. When the blade is not long enough or the blade is rusted or over-oxidized, a new blade needs to be replaced, so a blade box that can safely store multiple blades is needed. Traditional blade boxes are mostly composed of a box body and a box cover, and users need to manually take and put the blades. However, in order to prevent the blades from rusting, the blades are usually coated with anti-rust oil, which makes the adjacent blades fit tightly and inconvenient to take out. In addition, the blades are thin and one side is sharp. When taking out the blades, the blades are easy to scratch the hands, which poses a safety hazard. Existing blade boxes mostly use a push button and a blade to directly contact each other through friction to push the blade out of the blade box. However, since there is no clamping fixation between the push button and the blade, it is only pushed out through friction, which leads to failure of the blade to be pushed out, or it is easy to push out multiple blades at the same time. In addition, the push button cannot be automatically reset after the blade is pushed out, and it is often necessary to manually push the push button again to reset it, which is complicated and the efficiency of blade pushing is low. In view of the above problems, for example, a utility model patent with announcement number: CN212887703U discloses a blade box, which has a box body, an inner cavity for accommodating a blade, and an outlet is provided on the box body, wherein the inner cavity is located on one side of the blade and is provided with a push piece corresponding to the outlet, the push piece is slidably assembled on the box body to slide between a storage position and a push-out position, the storage position is a position where the push piece does not push the blade, the push-out position is a position where the push piece pushes the blade out of the box body, a push-butt edge is provided on the side of the push piece facing the blade, the push piece has a push-holding portion exposed outside the box body, and the inner cavity is provided with an elastic The invention relates to a blade box having a plurality of push-out members, wherein the push-out member is provided with a push-out member corresponding to the outlet on one side of the blade in the inner cavity of the box body, the push-out member is slidably assembled on the box body, a push-butting edge is provided on the side of the push-out member facing the blade, and an elastic element is provided in the inner cavity, the elastic force of the elastic element pushes the blade against the push-out member, and the blade can be smoothly pushed out by the push-out member. However, most of the current blade boxes use a convex rib structure to abut against the end of the blade to push the blade out. The transmission arm and distance required to push the blade are relatively long, the structure is complex and the use is relatively laborious. The present application provides a blade box with a new push-out structure, and the overall structure is more compact and the transmission coordination is more efficient. Summary of the invention

In the present scheme, an elastic pushing portion adapted to the mounting hole of the blade is provided on the switch, and the blade can be driven to extend from the opening through the buckle of the elastic pushing portion and the mounting hole. When the blade needs to be taken, the user presses the switch into place, and the switch slides under force so that the elastic pushing portion slides and buckles with the mounting hole of the blade. At this time, the first elastic member is in a compressed force state, and the user releases the switch, and the switch slides and resets under the action of the first elastic member. The elastic pushing portion drives the blade to slide out of the opening through sliding reset, which is convenient for the user to take it directly, and the switch automatically resets to facilitate the next use of the blade.
