Description

Technical Field

[0001] This utility model relates to the field of blade storage technology, and in particular to a blade box. Background Technology

[0002] In daily life and industrial production, blades are commonly used tools for cutting, trimming, and other operations. To facilitate storage and safe use, various types of blade holders have emerged on the market. However, existing blade holders still have certain design shortcomings, mainly in the following aspects: some lack a waste blade recycling function; others are inconvenient to retrieve.

[0003] For example, Chinese patent document CN101570017A discloses a blade box, including: a box body, which is a vertical structural component with an arc-shaped cross-section, an open bow chord surface, a blade outlet on the arc end face, and a through hole on the upper end face; a box lid, which is nested and connected to the bow chord surface of the box body; a spring guide rail, which is vertically installed in the box body and fixedly connected to the upper and lower end faces of the box body; a spring, which is fitted on the spring guide rail; a blade holder, which is fitted on the spring guide rail and presses against the spring; a set of blades, which is set on the blade holder; a blade extension push button, which presses against the blade and can drive a blade to extend from the blade outlet; and a push button, which is set on the upper end face of the box body and passes through the through hole on the upper end face and is fixedly connected to the blade extension push button. This patent uses a top push button to retrieve the internal blades, but it does not show how to recycle old blades, and the blade retrieval parts are relatively complicated. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The problem to be solved by this utility model is to provide a blade holder to overcome the defects in the prior art.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, this utility model provides a blade holder, including a receiving body, which is hollow to form a receiving cavity. A rotatable blade holder is provided at the lower opening of the receiving body, and a blade retrieval groove for accommodating a single blade is provided at the upper end of the blade holder. A blade retrieval port communicating with the receiving cavity is provided at the upper end of the receiving body. An upper top block and a lower top block are slidably disposed inside the receiving cavity, and an elastic element is provided between the upper top block and the lower top block. The upper top block forms a used blade stacking cavity with the upper wall of the receiving cavity, and used blades are inserted into this cavity through the blade retrieval port. The lower top block forms a new blade stacking cavity with the blade holder. When retrieving a blade, the blade holder is rotated open to remove a single new blade from the retrieval groove. When no used blade is inserted, the upper top block abuts against the upper wall of the receiving cavity.

[0008] In this design, the receiving cavity is divided into a new blade stacking cavity and an old blade stacking cavity by sliding an upper top block, a lower top block, and an elastic element within the receiving cavity. New blades are stacked in the new blade stacking cavity of the receiving cavity, and old blades are stacked in the old blade stacking cavity of the receiving cavity. Both new and old blades are always subjected to a pushing force. The lower top block pushes the stacked new blades downwards, facilitating the replenishment of new blades in the blade removal groove after removal. The receiving body is equipped with a blade recycling port, so used old blades do not need to be thrown away randomly; they can be recycled through the blade recycling port. When an old blade is inserted into the blade box or a new blade is removed, the new blade stacking cavity will relatively decrease in size, and the old blade stacking cavity will relatively increase in size. When no old blade is inserted, the upper top block is against the upper wall of the receiving cavity, and when no new blade is installed, the lower top block is located at the bottom of the receiving cavity.

[0009] In some embodiments, the blade holder is provided with a pin, and the housing is provided with a shaft hole corresponding to the pin. The pin is inserted into the shaft hole, and the blade holder rotates to open relative to the housing with the pin as the center.

[0010] In this solution, the blade holder can rotate smoothly through the cooperation of the pin and the shaft hole, allowing the user to rotate and open the blade holder to remove the blade.

[0011] In some embodiments, the lower end of the upper top block is provided with a plurality of protrusions, and the upper end of the lower top block is provided with a plurality of grooves that can cooperate with the protrusions; when the protrusions of the upper top block and the grooves of the lower top block are inserted into each other, the blade box can no longer store old blades in the blade box.

[0012] In some embodiments, when the blade holder rotates to retrieve the blade, the blade holder is provided with a plurality of raised limiting protrusions, which can prevent other blades from falling.

[0013] In this design, the limiting protrusion effectively prevents the blade from falling due to the pressure of the lower top block during the picking process. When the blade holder is reset, the limiting protrusion no longer blocks the blade from falling, and the blade can be replenished in the blade picking groove in a timely manner.

[0014] In some embodiments, the blade holder is further provided with a toggle part that facilitates the user to rotate the blade holder, and an avoidance cavity is provided on the outside of the blade removal groove. The avoidance cavity is used to facilitate the finger pinching of the blade when removing the blade, and a new blade is pulled out from one side of the avoidance cavity when removing the blade.

[0015] In some embodiments, a slide rail is provided on each side of the lid, and a protrusion corresponding to the slide rail is provided on the lower top block. Through the cooperation of the slide rail and the protrusion, the lower top block can slide vertically in the receiving cavity.

[0016] In some embodiments, the elastic element is configured as a spring structure.

[0017] In some embodiments, the upper top block is provided with a first groove for mounting the elastic element, and the lower top block is provided with a second flange for mounting the elastic element.

[0018] In some embodiments, the receiving body includes a box body and a box lid, the box body is provided with a buckle, and the box lid is provided with a slot that engages with the buckle.

[0019] In some embodiments, the lid is provided with an observation slot for observing the number of blades inside the receiving cavity. The design of the observation slot allows the user to intuitively understand the number of remaining blades inside the box.

[0020] (III) Beneficial Effects

[0021] This utility model provides a blade box that allows for easy retrieval of individual blades by rotating the blade holder. The upper and lower top blocks divide the receiving cavity into an old blade stacking cavity and a new blade stacking cavity, enabling the entire blade box to handle both new and old blade retrieval. A blade retrieval port allows used blades to be directly placed into the old blade stacking cavity. Multiple limiting protrusions on the blade holder effectively prevent other blades from falling during retrieval. The receiving body also features an observation groove and blade scale lines, allowing users to directly observe the remaining number of blades in the receiving cavity and promptly replace them with new blades, thus reusing the blade box.

[0037] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0038] See Figures 1 to 8 This utility model provides a blade box, including a receiving body 1, which is hollow to form a receiving cavity 5. The receiving body 1 has a rotatable blade holder 4 at its lower opening, and the blade holder 4 has a blade retrieval groove 401 at its upper end that can accommodate a single blade. The receiving body 1 has a blade recycling port 6 at its upper end that communicates with the receiving cavity 5. An upper top block 7 and a lower top block 8 are slidably provided inside the receiving cavity 5. An elastic member 9 is provided between the upper top block 7 and the lower top block 8. The upper top block 7 is used to form an old blade stacking cavity 501 with the upper wall of the receiving cavity 5. Used old blades are inserted into the old blade stacking cavity 501 from the blade recycling port 6. The lower top block 8 is used to form a new blade stacking cavity 502 with the blade holder 4. When retrieving a blade, the blade holder 4 is rotated open to remove a single new blade from the blade retrieval groove 401. When no old blade is inserted, the upper top block 7 is located on the upper wall of the receiving cavity 5.

[0039] When retrieving the blade, the rotating blade holder 4 is driven to rotate, and the blade retrieval groove 401 carries out the blade. At this time, the limiting protrusion 404 on the blade holder 4 blocks other blades from falling. After the blade is removed, the blade holder 4 is rotated to reset it. The elastic element 9 applies downward pressure, pushing the lower top block 8 to make the bottommost new blade fall into the blade retrieval groove 401. After the old blade is used up, it is inserted into the old blade stacking cavity 501 from the blade recycling port 6. The old blade and the new blade are separated by the upper top block 7 and the lower top block 8.

[0040] In some embodiments, such as Figure 2 As shown, the blade holder 4 is provided with a pin 402, which is inserted into the shaft hole 201 on the housing 2. The pin 402 serves as a fulcrum for rotation, allowing the blade holder 4 to rotate around the pin 402. With this structure, the blade holder 4 can be rotated open relative to the housing 2 to bring out the blade from the receiving cavity 5.

[0041] In some embodiments, such as Figure 2As shown, the blade holder 4 is provided with multiple raised limiting protrusions 404. These raised limiting protrusions 404 are used to block new blades in the new blade stacking cavity 502, preventing the blades from falling when the blade holder 4 rotates to remove the blades. The position of the limiting protrusions 404 ensures that when removing the blades, only one blade in the blade removal groove 401 can be brought out, and other blades will not be brought out.

[0042] In some embodiments, such as Figure 3 As shown, to facilitate user operation of the blade holder 4, a toggle part 403 is provided on the blade holder 4. The toggle part 403 is a protruding structure that allows the user to rotate the blade holder 4 with their fingers to perform blade removal or reset operations.

[0043] In some embodiments, such as Figure 2 As shown, each side of the lid 3 has a slide rail 10, which engages with the protrusion 11 on the lower top block 8. Through the engagement of the slide rail 10 and the protrusion 11, the lower top block 8 can slide vertically within the receiving cavity 5. When the user removes the blade, the lower top block 8 slides along the slide rail 10 under the action of the elastic element 9 to ensure smooth removal and replenishment of the blade.

[0044] In some embodiments, such as Figure 4 As shown, the elastic element 9 is configured as a spring structure. The two ends of the spring are connected to the upper top block 7 and the lower top block 8 respectively, ensuring that the elastic element 9 can apply downward pressure after the blade is removed, pushing the lower top block 8 so that the blade can be automatically replenished into the blade removal groove 401. The upper top block 7 is always subjected to an upward thrust, which can push the old blade against the upper wall of the receiving cavity 5, so that the old blade in the blade box will not shake.

[0045] In some embodiments, such as Figure 2 As shown, the lower end of the upper top block 7 has multiple protrusions 15, and the upper end of the lower top block 8 has multiple corresponding grooves 16 that can mate with the protrusions 15. When the protrusions 15 of the upper top block 7 and the grooves 16 of the lower top block 8 are inserted and engaged, old blades can no longer be stored in the blade box. Figure 4 As shown, this indicates that the blade box is "full". Only after taking out a new blade can an old blade be stored in the blade box.

[0046] In some embodiments, such as Figure 2 As shown, the upper top block 7 is provided with a first groove 701 for installing the elastic element 9, and the lower top block 8 is provided with a second flange 801 for installing the elastic element 9.

[0047] In some embodiments, such as Figure 5 As shown, a clearance cavity 405 is also provided on the outside of the knife-removing groove 401. The clearance cavity 405 is used to facilitate the finger gripping of the blade when removing the knife. The clearance cavity 405 is located at one end away from the rotating hinge of the blade holder 4.

[0048] like Figure 7 As shown, when removing the blade, the new blade is pulled out from one side of the clearance cavity 405.

[0049] In some embodiments, such as Figure 5 As shown, the housing 1 includes a box body 2 and a lid 3. The box body 2 is provided with a buckle 12, and the lid 3 is provided with a slot 13 that cooperates with the buckle 12. When the user closes the lid 3, the buckle 12 and the slot 13 are tightly engaged to ensure that the lid 3 is fixed on the box body 2.

[0050] In some embodiments, such as Figure 1 As shown, to facilitate user observation of the number of blades in the receiving cavity 5, the cover 3 is provided with an observation slot 14. This observation slot 14 allows the user to visually see the number of remaining blades in the receiving cavity 5.

[0051] In some embodiments, the scale lines on the product clearly show the number of remaining blades in the receiving cavity 5, allowing for timely replacement of new blades inside the receiving cavity 5 and reuse of the blade box.

[0052] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
