Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hand tool technology, and in particular relates to a storage box for utility knife blades. Background Technology
[0002] A utility knife, also known as a carving knife or wallpaper knife, is a common hand tool primarily used for cutting thin materials such as paper, plastic, thin wood panels, and wallpaper. Due to its simple structure, ease of operation, and precise cutting ability, it is widely used in art creation, handicrafts, interior decoration, and office work. Because the blade of a utility knife wears down during use, leading to a decrease in cutting performance, it needs to be replaced regularly. To improve blade replacement efficiency and ensure safe storage, current technology generally adopts a box-type blade storage design.
[0003] Currently, utility knife razor blade holders on the market mainly fall into two types: The first type uses a traditional open-top design, which is simple in structure, but users must completely open the box to retrieve the stored blades. This is not only cumbersome but also poses a safety hazard of blades cutting the user during retrieval. The second type uses a push-rod design, with an opening on the box that allows the blades to be pushed out. While this design eliminates the need to open the box, significantly improving ease of operation and efficiency, the blades may accidentally slip out of the opening if the box is tilted during storage, also posing a safety risk.
[0004] Therefore, there is an urgent need for a storage box for utility knife blades to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a storage box for utility knife blades, which can remove utility knife blades without opening the box, making the operation convenient and quick, improving the convenience and efficiency of removing utility knife blades, and also ensuring that the utility knife blades will not slip out of the box during daily use, thus ensuring the safety of the storage of utility knife blades.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A storage box for utility knife blades is provided, comprising:
[0008] The box body has a storage cavity for storing utility knife blades, and a blade retrieval port is provided at one end of the box body along its extension direction.
[0009] A pusher is movably disposed on the box body along the extension direction of the box body. The pusher includes an operating part and a limiting part connected together. The operating part is located outside the box body. The limiting part is provided with a limiting groove. The utility knife blade can be embedded in the limiting groove. The limiting part has a storage position that limits the utility knife blade as a whole in the storage cavity and a feeding position that allows the utility knife blade to extend out of the dispensing port. When the limiting part is in the feeding position, the utility knife blade can disengage from the limiting groove. When the operating part is driven to move along the extension direction of the box body, the operating part can drive the utility knife blade embedded in the limiting groove to move towards the feeding position through the limiting part.
[0010] Optionally, the limiting part includes a plate, a stop block, and a push block. The plate extends along the extension direction of the box body, the stop block is located at one end of the plate near the dispensing port, and the push block is located at the other end of the plate body. The space between the stop block and the push block forms at least a partial limiting groove.
[0011] Optionally, the storage cavity contains multiple utility knife blades, which are stacked along the thickness direction of the box body. One of the multiple utility knife blades can be embedded in the limiting groove. The thickness of the push block is no greater than the thickness of a single utility knife blade, and the thickness of the stop block is no greater than twice the thickness of a single utility knife blade.
[0012] Optionally, the storage cavity contains multiple utility knife blades, which are stacked along the thickness direction of the box body, and one of the utility knife blades can be embedded in the limiting groove.
[0013] The storage box for utility knife blades also includes a blocking member disposed on the box body. The blocking member and the limiting part are arranged at intervals along the thickness direction of the box body. The blocking member is configured to limit several utility knife blades, except for those embedded in the limiting groove, within the box body.
[0014] Optionally, when the limiting part is in the storage position, the blocking member and the bottom wall of the limiting groove are arranged at intervals along the thickness direction of the utility knife blade; the minimum distance between the blocking member and the bottom wall of the limiting groove is not less than the thickness of a single utility knife blade, and not more than twice the thickness of a single utility knife blade.
[0015] Optionally, the housing is provided with a connecting hole extending along its extension direction, and the pusher also includes a connecting part, one end of which is connected to the operating part, and the other end passes through the connecting hole and is connected to the limiting part, and the position of the connecting part in the connecting hole is adjustable.
[0016] Optionally, a groove is formed between the operating part, the connecting part and the limiting part, and a sliding part is provided on the box body, the sliding part being located in the groove and slidingly engaging with the groove.
[0017] Optionally, the storage box for utility knife blades also includes an elastic element disposed in the storage cavity. The elastic element is located at the first end of the box body, and the pushing element is located at the second end of the box body. Multiple utility knife blades can be stacked between the elastic element and the limiting part. The utility knife blades near the first end of the box body can contact the elastic element, and the utility knife blades near the second end of the box body can be embedded in the limiting groove. When the utility knife blades embedded in the limiting groove are disengaged from the limiting groove, several utility knife blades not embedded in the limiting groove can move towards the second end of the box body under the elastic force of the elastic element until the utility knife blades near the second end of the box body are embedded in the limiting groove. The first end and the second end are the two ends of the box body along its thickness direction.
[0018] Optionally, the box body is provided with a groove extending along its extension direction, the operating part is located in the groove, and the top surface of the operating part is not higher than the groove opening.
[0019] Optionally, the box body includes a first main body and a second main body that are detachably connected. The first main body and the second main body surround a tablet storage cavity, and the tablet dispensing port is located in the first main body.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This utility model provides a storage box for utility knife blades. When the operating part is moved along the extension direction of the box body, the operating part drives the limiting part to move from the storage position to the feeding position. The limiting part drives the utility knife blade, which is embedded in the limiting groove, from a position where it is entirely confined within the storage cavity to the direction of the dispensing opening, until the utility knife blade moves to the point where it can extend out of the dispensing opening. That is, when the limiting part is in the feeding position, the utility knife blade can at least partially extend out of the box body. At this time, by applying a certain force to the utility knife blade, the blade blade can be removed from the limiting groove. This allows the user to remove the utility knife blade without opening the box body, making the operation convenient and quick, and improving the convenience and efficiency of utility knife blade removal. The utility knife blade is embedded in the limiting groove, and the groove wall of the limiting groove can restrict the movement of the utility knife blade, helping to prevent the utility knife blade from automatically sliding out of the dispensing opening. Even if the box body is tilted during daily use, the utility knife blade will not slide out of the dispensing opening, ensuring the safety of the utility knife blade stored in the storage cavity.

Therefore, they should not be construed as limitations on this utility model.
[0036] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] like Figures 1 to 7 As shown, this embodiment provides a storage box for utility knife blades, which allows the utility knife blades 100 to be taken out without opening the box body 1. The operation is convenient and quick, improving the convenience and efficiency of taking out the utility knife blades 100. It also ensures that the utility knife blades 100 will not slide out of the box body 1 during daily use, thus guaranteeing the safety of the storage of the utility knife blades 100.
[0039] See Figure 1 and Figure 2 The storage box for utility knife blades includes a box body 1 and a pusher 2. The box body 1 is provided with a storage cavity 11 for storing utility knife blades 100. The box body 1 extends along its extension direction ( Figure 1 One end of the box (in the X direction) is provided with a chip pick-up port 121; the pusher 2 is movably disposed on the box 1 along the extension direction of the box 1. The pusher 2 includes a connected operating part 21 and a limiting part 22. The operating part 21 is located outside the box 1. The limiting part 22 is provided with a limiting groove 221. The utility knife 100 can be embedded in the limiting groove 221. The limiting part 22 has a storage position that limits the utility knife 100 as a whole in the chip storage cavity 11 and a feeding position that allows the utility knife 100 to extend out of the chip pick-up port 121. When the limiting part 22 is in the feeding position, the utility knife 100 can disengage from the limiting groove 221. When the operating part 21 is driven to move along the extension direction of the box 1, the operating part 21 can drive the utility knife 100 embedded in the limiting groove 221 to move towards the feeding position through the limiting part 22.
[0040] The storage box for utility knife blades provided in this embodiment, when the operating part 21 moves along the extension direction of the box body 1, drives the limiting part 22 to move from the storage position to the feeding position. The limiting part 22 drives the utility knife blade 100 embedded in the limiting groove 221 from the position where it is entirely limited within the storage cavity 11 to the direction of the dispensing port 121, until the utility knife blade 100 moves to the point where it can pass through the dispensing port 121. That is, when the limiting part 22 is in the feeding position, the utility knife blade 100 can at least partially be located outside the box body 1. At this time, by applying a certain force to the utility knife blade 100 by hand, the utility knife blade 100 can be taken out from the limiting groove 221, so that the user can take out the utility knife blade 100 without opening the box body 1. The operation is convenient and quick, improving the convenience and efficiency of taking out the utility knife blade 100. The utility knife blade 100 is embedded in the limiting groove 221. The groove wall of the limiting groove 221 can restrict the movement of the utility knife blade 100, which helps to prevent the utility knife blade 100 from automatically sliding out of the dispensing port 121. Even if the box body 1 is tilted during daily use, the utility knife blade 100 will not slide out of the dispensing port 121, thus ensuring the safety of the utility knife blade 100 stored in the storage cavity 11.
[0041] Optionally, see Figure 2 , Figure 3 and Figure 4 The limiting part 22 includes a plate 222, a stop 223, and a pusher 224. The plate 222 extends along the extending direction of the box body 1. The stop 223 is located at one end of the plate 222 near the dispensing port 121, and the pusher 224 is located at the other end of the plate 222. The space between the stop 223 and the pusher 224 forms at least a partial limiting groove 221. This arrangement ensures that the stop 223 can always restrict the movement of the utility knife blade 100 within the limiting groove 221, whether in the storage position or the feeding position, thus ensuring safety during daily use. When the limiting part 22 moves from the storage position to the feeding position, the pusher 224 can push the utility knife blade 100 located in the limiting groove 221 to move together, so as to remove the utility knife blade 100 from the dispensing port 121.
[0042] Specifically, the plate 222 and the utility knife 100 are arranged in parallel. The space between the plate 222, the stop 223 and the push block 224 forms a rectangular groove, which is the limiting groove 221. The utility knife 100 embedded in the limiting groove 221 can contact the plate surface of the plate 222, the side of the stop 223 facing the push block 224, and the side of the push block 224 facing the stop 223.
[0043] In this embodiment, see Figure 2 , Figure 3 and Figure 4 The storage cavity 11 contains multiple utility knife blades 100, which are arranged along the thickness direction of the box body 1. Figure 2The multiple utility knife blades 100 are stacked in the Z-direction, with one of them able to be embedded in the limiting groove 221. The thickness of the push block 224 is no greater than the thickness of a single utility knife blade 100, and the thickness of the stop block 223 is no greater than twice the thickness of a single utility knife blade 100. The fact that the thickness of the push block 224 is no greater than the thickness of a single utility knife blade 100 ensures that when the limiting part 22 moves from the storage position to the feeding position, it can only move one utility knife blade 100 at a time, which helps improve the safety of removing the utility knife blade 100 and enhances the user experience.
[0044] For example, the thickness of the stop 223 is less than the thickness of a single utility knife blade 100, so that the user can remove the utility knife blade 100 from the limiting groove 221 at the feeding position; in other embodiments, the thickness of the stop 223 is equal to the thickness of a single utility knife blade 100, or the thickness of the stop 223 is greater than the thickness of a single utility knife blade 100 but less than twice the thickness of a single utility knife blade 100.
[0045] For example, see Figure 2 , Figure 3 and Figure 4 There are two stops 223, which are symmetrically arranged on the utility knife blade 100 along its width direction. Figure 2 On both sides of the Y direction in the middle; three push blocks 224 are provided, and three stop blocks 223 are arranged at intervals along the width direction of the utility knife blade 100.
[0046] Optionally, see Figure 2 The storage cavity 11 stores a plurality of utility knife blades 100, which are stacked along the thickness direction of the box body 1. One of the utility knife blades 100 can be embedded in the limiting groove 221. The storage box for utility knife blades also includes a blocking member 3 disposed on the box body 1. The blocking member 3 and the limiting part 22 are arranged at intervals along the thickness direction of the box body 1. The blocking member 3 is configured to limit a plurality of utility knife blades 100, except for the utility knife blades 100 embedded in the limiting groove 221, within the box body 1. This design ensures that no matter how the box 1 is tilted during storage, multiple utility knife blades 100 cannot slide out between the blocking member 3 and the limiting member 22, further improving the stability and safety of the utility knife blades 100 during storage. Moreover, when the limiting member 22 moves the utility knife blades 100 embedded in the limiting groove 221, the blocking member 3 can prevent the movement of other utility knife blades 100, ensuring that only the utility knife blades 100 embedded in the limiting groove 221 can be removed from the blade removal port 121 each time, which helps to improve the safety of removing the utility knife blades 100 and enhance the user experience.
[0047] See Figure 2The blocking member 3 is a side plate of the box body 1 and is located on the same side as the tablet dispensing port 121. The side wall of the blocking member 3 facing the inside of the box body 1 forms a cavity wall of the tablet storage cavity 11, and the gap between the blocking member 3 and the limiting part 22 forms the tablet dispensing port 121. Specifically, when the limiting part 22 is in the storage position, multiple utility knife blades 100 are located in the tablet storage cavity 11, and at this time, multiple utility knife blades 100 are located on one side of the blocking member 3; when the limiting part 22 is in the feeding position, the utility knife blades 100 embedded in the limiting groove 221 pass through the gap between the blocking member 3 and the limiting part 22, and several utility knife blades 100 not embedded in the limiting groove 221 are still located on one side of the blocking member 3.
[0048] In this embodiment, when the limiting part 22 is in the storage position, the blocking member 3 and the bottom wall of the limiting groove 221 are arranged at intervals along the thickness direction of the utility knife blade 100; the minimum distance between the blocking member 3 and the bottom wall of the limiting groove 221 is not less than the thickness of a single utility knife blade 100 and not more than twice the thickness of a single utility knife blade 100, so that when the limiting part 22 moves from the storage position to the feeding position, several utility knife blades 100 other than those embedded in the limiting groove 221 can be limited by the blocking member 3 to the storage position.
[0049] The bottom wall of the limiting groove 221 is the plate surface of the plate 222 facing the utility knife blade 100.
[0050] Optionally, see Figure 5 and Figure 6 The box body 1 is provided with a connecting hole 122 extending along its extension direction. The pusher 2 also includes a connecting part 23. One end of the connecting part 23 is connected to the operating part 21, and the other end passes through the connecting hole 122 and is connected to the limiting part 22. The position of the connecting part 23 within the connecting hole 122 is adjustable. The connection hole 122 allows the connecting part 23 to move along the extension direction of the box body 1. Thus, when the user pushes the operating part 21 to move along the extension direction of the box body 1, the operating part 21 drives the limiting part 22 to move through the connecting part 23, realizing the linkage between the operating part 21 and the limiting part 22.
[0051] In this embodiment, see Figure 5 and Figure 6 A groove 24 is formed between the operating part 21, the connecting part 23, and the limiting part 22. A sliding part 123 is provided on the box body 1. The sliding part 123 is located in the groove 24 and slides in cooperation with the groove 24. This arrangement allows the sliding part 123 to stably install the pusher 2 on the box body 1 through the groove wall of the groove 24 without affecting the movement of the pusher 2.
[0052] For example, see Figure 5 and Figure 6The cross-sectional shape of the pusher 2 is I-shaped. The operating part 21 and the limiting part 22 are the two flanges of the pusher 2, the connecting part 23 is the web of the pusher 2, and the slide groove 24 is the space between the web and the flange of the I-shaped pusher 2. There are two sliding parts 123. The wall of the hole 122 extending along the extension direction of the box body 1 is a sliding part 123. The two sliding parts 123 correspond one-to-one with the two slide grooves 24, which helps to improve the stability of the pusher 2 when it moves as a whole.
[0053] Optionally, see Figure 2 The storage box for utility knife blades also includes an elastic element 4 disposed in the storage cavity 11. The elastic element 4 is located at the first end of the box body 1, and the pushing element 2 is located at the second end of the box body 1. Multiple utility knife blades 100 can be stacked between the elastic element 4 and the limiting part 22. The utility knife blades 100 near the first end of the box body 1 can contact the elastic element 4, and the utility knife blades 100 near the second end of the box body 1 can be embedded in the limiting groove 221. When the utility knife blades 100 embedded in the limiting groove 221 are dislodged from the limiting groove 221, several utility knife blades 100 that are not embedded in the limiting groove 221 can move towards the second end of the box body 1 under the elastic force of the elastic element 4 until the utility knife blades 100 near the second end of the box body 1 are embedded in the limiting groove 221. The first end and the second end are the two ends of the box body 1 along its thickness direction. This design allows the utility knife blade 100 in the storage cavity 11 to automatically move towards the limiting groove 221 under the action of elastic force after the utility knife blade 100 in the limiting groove 221 is removed, thereby realizing automatic replenishment of the utility knife blade 100 in the limiting groove 221 without manual operation by the user, thus improving the user experience.
[0054] For example, see Figure 2 In the orientation, the thickness direction of box 1 is horizontal, the first end is the right end of box 1, and the second end is the left end of box 1.
[0055] In this embodiment, see Figure 2 and Figure 7The elastic element 4 includes a first elastic part 41 and two second elastic parts 42. The two second elastic parts 42 are respectively disposed at both ends of the first elastic part 41. The first elastic part 41 can contact the utility knife 100 near the first end of the box body 1. The end of the second elastic part 42 away from the first elastic part 41 slides in cooperation with the box body 1. This configuration ensures that when utility knife blades 100 are filled into the tablet storage cavity 11, the overall weight of the multiple utility knife blades 100 increases with the number of blades 100. The utility knife blades 100 near the first end will compress the first elastic part 41 and move it away from the utility knife blade 100. The first elastic part 41 compresses the second elastic part 42 to slide on the box body 1, causing the overall size of the elastic element 4 along the thickness direction of the box body 1 to decrease, and the elastic element 4 can accumulate elastic potential energy. When the limiting part 22 moves the utility knife blades 100 near the second end out of the tablet storage cavity 11, the compressive force of the utility knife blades 100 on the first elastic part 41 decreases, and the second elastic part 42 has a tendency to recover its deformation. The second elastic part 42 drives the first elastic part 41 to move towards the utility knife blade 100, thereby realizing the automatic replenishment of the utility knife blades 100 to the limiting groove 221.
[0056] For example, see Figure 7 The elastic element 4 is a spring sheet with a trapezoidal cross-sectional shape. The first elastic part 41 is the top surface of the trapezoidal spring sheet, and the second elastic part 42 is the inclined surface of the trapezoidal spring sheet.
[0057] Optionally, see Figure 1 , Figure 2 and Figure 5 The box body 1 has a groove 124 extending along its extension direction. The operating part 21 is located within the groove 124, and the top surface of the operating part 21 is not higher than the opening of the groove 124. This design makes it less likely for the operating part 21 to be accidentally touched by the user during storage, effectively reducing the possibility of the utility knife 100 being removed from the box body 1 due to accidental touching of the operating part 21, and further improving the safety of the utility knife 100 during storage. The groove 124 extends along the extension direction of the box body 1, ensuring that the groove 124 does not affect the movement of the operating part 21 on the box body 1, thus ensuring the smooth movement of the operating part 21.
[0058] Optionally, see Figure 2 and Figure 6 The box body 1 includes a first main body 12 and a second main body 13 that are detachably connected. The first main body 12 and the second main body 13 surround a storage cavity 11, and a dispensing port 121 is provided on the first main body 12. After all the utility knife blades 100 in the storage cavity 11 have been removed, the user can separate the first main body 12 and the second main body 13 to supply new utility knife blades 100 into the storage cavity 11. This allows the storage box for utility knife blades provided in this embodiment to be reused, reducing the usage cost of the storage box for utility knife blades.
[0059] In this embodiment, see Figure 2 The first body 12 is a cube, the second body 13 is the end cap of the first body 12, and the second body 13 and the plate-taking port 121 are respectively located at both ends of the first body 12 along its extension direction.
[0060] For example, the first body 12 and the second body 13 are snapped together.
[0061] Optionally, see Figure 3 The operating part 21 is provided with a plurality of protrusions 211, which are arranged at intervals along the extending direction of the housing 1. The arrangement of the plurality of protrusions 211 can increase the friction between the user and the operating part 21 when the operating part 21 is pushed to move, prevent the user's hand from slipping, and improve the stability of the user pushing the operating part 21 to move.
[0062] For example, see Figure 3 The cross-sectional shape of the protrusion is semi-circular, which helps to improve the user's pushing feel and enhance the user experience.
[0063] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
