Description

Technical Field

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

[0002] Replaceable blades for utility knives are usually stacked and stored in a storage box. The stacked blades will stick together due to the negative pressure created by the anti-rust oil, making it difficult for users to separate individual blades from the stack. This can easily result in cuts to the fingers and a lot of oil stains.

[0003] Existing storage boxes use a button to hang a single layer of blades, and releasing the button causes the blades to pop out simultaneously. During the pop-out process, if a finger slips, the button will return to its original position at high speed under the spring's restoring force. This causes the blades to gain significant kinetic energy and be ejected from the box at high speed, potentially causing injury to the user. Furthermore, the blades may remain at a high speed even after fully ejecting from the box, potentially causing other accidental injuries to the surrounding environment.

[0004] The above description of "prior art" provides background information only and does not acknowledge that the above description of "prior art" discloses the subject matter of this application. It does not constitute prior art of this application, and no description of the above "prior art" should be considered part of this application. Utility Model Content

[0005] The main purpose of this application is to provide a blade storage box that can reduce the speed at which the blade pops out, thus preventing user injury or other accidental damage.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] According to one aspect of this application, a blade storage box is provided, comprising a box body, a base plate, a button, an elastic element, a plurality of blades, and a damping element. The box body has a notch. The base plate is connected to the box body and defines a cavity with the box body. The button is disposed at the notch, and the button and the side wall of the box body have a slit for the blade to pass through. The button has a hook portion extending into the cavity, the free end of which is used to hook the blade and eject the blade through the slit into the blade storage box. The elastic element is disposed on the base plate and provides an elastic force toward the button. The plurality of blades are stacked and located between the elastic element and the button. The damping element is disposed on the button and contacts the blade, the damping force of the damping element being adjustable according to the direction of movement of the blade.

[0008] According to one embodiment of this application, the damping element includes a body and at least one damping arm, the damping arm being connected to the body, the body being mounted on the button, and the damping arm contacting the blade.

[0009] According to one embodiment of this application, the damping arm is L-shaped and includes a first arm and a second arm connected to each other. The first arm is connected to a surface of the body, and the distance between the free end of the second arm and the surface of the body is less than the distance between the connecting end of the second arm and the surface of the body.

[0010] According to one embodiment of this application, there are multiple damping arms, arranged in a row or array on the body, wherein the free ends of the second arm of each damping arm face the same direction.

[0011] According to one embodiment of this application, the free end of the second arm is oriented away from the slit.

[0012] According to one embodiment of this application, the angle between the surface of the first arm facing away from the second arm and the surface of the body is greater than 90°.

[0013] According to one embodiment of this application, the second arm contacts the blade, and the contact area of ​​the second arm with the blade varies depending on the direction of movement of the blade, thereby allowing the damping force to change according to the direction of movement of the blade.

[0014] According to one embodiment of this application, the button further includes a receiving cavity for accommodating the damping element, the size of the receiving cavity being smaller than the maximum size of the damping element, and the damping element elastically deforming and being accommodated within the receiving cavity.

[0015] According to one embodiment of this application, the housing includes at least one bearing surface located in the cavity for bearing the blade, the bearing surface and the damping member being located on the same side of the blade, and the damping member protruding from the bearing surface when the damping member is not in contact with the blade.

[0016] According to one embodiment of this application, the damping element is made of a highly elastic polymeric material.

[0017] As can be seen from the above technical solution, the advantages and positive effects of the blade storage box proposed in this application are as follows:

[0018] The blade storage box proposed in this application has a damping element on the part of the button facing the blade that contacts the blade surface. When the blade pops out of the storage box at high speed, the surface of the blade that contacts the damping element slides relative to the damping element. Thus, the damping element can apply a damping force to the blade surface in the opposite direction of the blade's movement. This can reduce the blade popping speed and prevent user injury or other accidental damage.

[0019] The blade storage box proposed in this application features a damping force in its damping component that can be adjusted according to the blade's direction of movement. The damping force provided by the damping component when the blade is ejected from the storage box at high speed differs from the damping force provided when the blade is retracted into the storage box under external force. This design ensures that, while preventing user injury or other accidental damage, the storage box will not make blade retraction difficult due to the damping component. Attached Figure Description

[0060] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0061] In the following description of various exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form part of the present invention, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of the present invention. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of the present invention. Furthermore, although the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein only for convenience, such as the orientation according to the examples shown in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention.

[0062] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0063] Relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship of one element to another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, and the term “bottom” can include both “bottom” and “top” orientations, depending on the specific orientation of the figure. Similarly, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “bottom” or “below” can include both “up” and “down” orientations.

[0064] like Figures 1 to 5 As shown, the blade storage box 1 of this application includes a box body 10, a base plate 20, a button 30, an elastic element 40, a plurality of blades 2, and a damping element 304. The box body 10 has a notch 101. The base plate 20 is connected to the box body 10 and defines a cavity 102 with the box body 10. The button 30 is disposed in the notch 101 and can slide relative to the box body 10 within the notch 101. The base plate 20 is detachably connected to the box body 10. When the base plate 20 is detached, blades 2 can be placed or added to the box body 10. The button 30 and the side wall of the box body 10 have a slit 301, through which the blades 2 can be ejected from the storage box 1, or retracted into the storage box 1 under external force. The button 30 has a hook portion 302 extending into the cavity 102. The free end of the hook portion 302 is used to hook the blades 2 and eject the blades 2 from the blade storage box 1 through the slit 301. An elastic element 40 is disposed on the base plate 20 and provides an elastic force toward the button 30. In this embodiment, the elastic element 40 is an arched spring sheet, with several blades 2 stacked and located between the button 30 and the elastic element 40. The elastic element 40 provides an upward elastic force toward the button 30 to the stacked blades 2, thereby causing the button 30 to provide a downward force toward the elastic element 40 to the blades 2. A damping element 304 is disposed on the portion of the button 30 facing the blades 2. The damping element 304 contacts the blades 2, and the value of the damping force of the damping element 304 can be changed according to the different movement directions of the blades 2.

[0065] The blade storage box 1 of this application has a hook 302 on the button 30 that hooks the desired blade 2. Then the blade 2 pops out from the slit 301 along with the button 30. This makes it safer and more convenient for the user to take the blade 2 out of the storage box, so that when the user takes the blade 2, there will be no difficulty in peeling it off or easy injury.

[0066] The blade storage box 1 of this application has a damping element 304 on the part of the button 30 facing the blade 2, and the damping element 304 is close to the slit 301. When the blade 2 pops out of the storage box 1, the damping force generated by the damping element 304 on the blade 2 will increase. This can prevent the blade 2 from gaining too much kinetic energy and ejecting out of the box 10 at high speed, causing injury to the user; it can also prevent the blade 2 from maintaining a high speed when it is fully ejected from the box 10, causing other accidental injuries to the surrounding environment. When the ejected blade 2 needs to be returned to the storage box 1, an external force pushes the blade 2 to move in the opposite direction to the direction in which the blade 2 popped out. At this time, the damping force applied to the blade 2 by the damping element 304 will decrease, and the blade 2 can be returned to the storage box 1 more easily.

[0067] The blade storage box 1 of this application can ensure that, while preventing user injury or other accidental damage, the storage box 1 will not make it difficult to retract the blade 2 due to the setting of the damping element 304.

[0068] Regardless of whether the blade 2 is present between the elastic element 40 and the button 30, the elastic element 40 is always in a compressed state, meaning it always provides an elastic force towards the button 30. The free end of the hook portion 302 of the button 30 includes a protrusion 303, which hooks the blade 2 and prevents it from detaching from the button 30. The protrusion 303 can also apply the force generated by the movement of the button 30 to the blade 2, thereby causing it to pop out. The shape of the protrusion 303 matches the shape of the end of the blade 2. Since the end of the blade 2 is inclined relative to its length, the protrusion 303 is also inclined, ensuring that the hook portion 302 securely and stably hooks the end of the blade 2.

[0069] In this embodiment, see Figure 2 and Figure 3 Button 30 can switch between a first position without external force and a second position with external force. After the storage box 1 is installed, button 30 will not detach from the box body 10 when switching between the first and second positions. Button 30 may be provided with a limiting structure to restrict the position of button 30 relative to the box body 10. When button 30 is in the second position, the free end of hook 302 can hook the blade. A limiting structure may be formed between the outer wall of the box body 10 and the outer wall of button 30 (see...). Figure 3 When an external force pushes button 30 from the first position to the second position, the hook portion 302 of button 30, which extends into the cavity 102 of the housing 10, moves accordingly to one end of the blade 2 facing away from the slit 301. Since the end of the blade 2 is inclined, the protrusion 303 of the hook portion 302 of button 30 can hook the end of the blade 2 when button 30 is in the second position, so that a pushing force can be applied to the blade 2 to eject the blade 2 from the storage box 1 (see [reference]). Figure 4 and Figure 5 When button 30 rebounds from the second position to the first position, a limiting structure is provided between button 30 and housing 10 to prevent button 30 from disengaging from housing 10. This can be a protrusion and a stop, or a structure where a protrusion slides in a groove, with the end of the groove providing a limiting position. The stop or groove is located in housing 10, and the protrusion is located in button.

[0070] In this embodiment, see Figures 2 to 6 The damping element 304 includes a body 3041 and at least one damping arm 3042. In this embodiment, there are four damping arms 3042 arranged side by side. The damping arm 3042 is connected to the body 3041, which is mounted on the button 30. The damping arm 3042 contacts the blade 2. The body 3041 is connected to the button 30, and the damping arm 3042 faces the blade 2 and can apply a damping force to the blade 2. This ensures that while preventing user injury or other accidental damage, the storage box 1 will not have difficulty retracting the blade 2 due to the damping element 304.

[0071] In this embodiment, see Figures 6 to 7 The damping arm 3042 is L-shaped and includes a first arm 30421 and a second arm 30422 connected to each other. The first arm 30421 is connected to a surface 30411 of the body 3041. The distance D1 between the free end of the second arm 30422 and the surface 30411 of the body 3041 is smaller than the distance D2 between the connecting end of the second arm 30422 and the surface 30411 of the body 3041. When the blade 2 moves in different directions, the direction of the force applied by the blade 2 to the damping arm 3042 is different. The L-shaped damping arm 3042 allows the second arm 30422 to swing relative to the first arm 30421 under different forces applied by the blade 2, thereby changing the contact area between the second arm 30422 and the blade 2. This causes the value of the damping force of the damping element 304 to change with the different directions of movement of the blade 2.

[0072] In this embodiment, the free ends of the second arms 30422 of each damping arm 3042 face the same direction, ensuring that the damping force generated by each damping arm 3042 remains the same. The free ends of the second arms 30422 all face away from the slit 301. When the blade 2 is ejected outward from the housing 10 of the storage box 1 through the slit 301, the blade 2 will push the second arm 30422 of the damping member 304 towards the slit 301, allowing the free end of the second arm 30422 to swing relative to the first arm 30421. This increases the contact area between the second arm 30422 and the blade 2, increasing the damping force applied to the blade 2 by the damping member 304, thereby reducing the ejection speed of the blade 2. When the ejected blade 2 needs to be retracted into the storage box 1, an external force pushes the blade 2 to move in the opposite direction to the direction in which it was ejected. At this time, the blade 2 will push the second arm 30422 of the damping member 304 away from the slit 301, so that the free end of the second arm 30422 can swing relative to the first arm 30421 in the opposite direction to the previous swing. As a result, the contact area between the second arm 30422 and the blade 2 is reduced, the damping force applied by the damping member 304 to the blade 2 is reduced, and the blade 2 can be retracted into the storage box 1 more easily.

[0073] In this embodiment, see Figure 7 The angle α between the surface of the first arm 30421 facing away from the second arm 30422 and the surface 30411 of the body 3041 is greater than 90°. This ensures a firm connection between the damping arm 3042 and the body 3041, preventing the damping arm 3042 from separating from the body 3041 under the reciprocating force of the blade 2.

[0074] In this embodiment, see Figures 2 to 7 The second arm 30422 contacts the blade 2. The contact area of ​​the second arm 30422 with the blade 2 varies depending on the direction of movement of the blade 2, thereby allowing the damping force to change according to the direction of movement of the blade 2.

[0075] In this embodiment, see Figures 2 to 5The button 30 includes a guide post 305. A raised wall 103 is provided on the housing 10, and a guide hole 104 is provided on the raised wall 103. The guide post 305 passes through the guide hole 104 and can move along the guide hole 104. The movement of the guide post 305 along the guide hole 104 enables the button 30 to move, thus allowing the button 30 to switch between a first position and a second position. The button 30 also includes a push-press part 306. One end of the guide post 305 is connected to the push-press part 306, and the other end is a free end. A compression spring 307 is provided on the guide post 305, located between the push-press part 306 and the raised wall 103. The compression spring 307 ensures that the button 30 is in the first position or moves towards the first position when no external force is applied, thereby causing the blade 2 to pop out of the slit 301, enabling the blade 2 to be retrieved.

[0076] In this embodiment, see Figures 8 to 9 The button 30 also includes a receiving cavity 308 for accommodating the damping element 304. The size of the receiving cavity 308 is smaller than the maximum size of the damping element 304, and the damping element 304 is elastically deformed and accommodated in the receiving cavity 308.

[0077] In this embodiment, see Figures 2 to 5 , Figures 10 to 11 The housing 10 includes at least one bearing surface 105 located in the cavity 102 for bearing the blade 2. The bearing surface 105 and the damping element 304 are located on the same side of the blade 2. When the damping element 304 is not in contact with the blade 2, the damping element 304 protrudes from the bearing surface 105. The protrusion of the damping element 304 from the bearing surface 105 ensures that when the blade 2 is installed, under the action of the elastic element 40, it first contacts the damping element 304 and then contacts the bearing surface 105. This ensures that the damping element 304 and the blade 2 are always in contact, and that the damping force of the damping element 304 can change with the different movement directions of the blade 2.

[0078] In this embodiment, the damping element 304 is made of a highly elastic polymeric material, such as natural rubber, synthetic rubber, or thermoplastic elastomer; more specifically, it can be vulcanized silicone rubber.

[0079] The blade storage box 1 of this application also has a second embodiment, wherein the blade storage box 1 of the second embodiment is related to... Figures 1 to 11 Compared to the blade storage box 1 of the second embodiment, it has a substantially the same structure in its basic construction. Therefore, in the following description of the blade storage box 1 of this second embodiment, the description will not be repeated. Figures 1 to 11 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 11 The blade storage box 1 described in the embodiment has the same structure and is labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structure will mainly be compared with the blade storage box 1 described in the embodiment. Figures 1 to 11The differences between the blade storage box 1 in this second embodiment and the previous embodiment will be explained. Specifically, the main difference in this second embodiment is the number and arrangement of the damping arms 3042 of the damping member 304. Figures 1 to 11 In one embodiment, four damping arms 3042 are arranged side by side. In this second embodiment, eight damping arms 3042 are arranged in an array. In other embodiments, the number of damping arms 3042 may be other numbers, arranged in an array or side by side.

[0080] The blade storage box 1 of this application also has a third embodiment, wherein the blade storage box 1 of the third embodiment is related to... Figures 1 to 11 Compared to the blade storage box 1 of the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the blade storage box 1 of this third embodiment, the description will not be repeated. Figures 1 to 11 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 11 The blade storage box 1 described in the embodiment has the same structure and is labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structure will mainly be compared with the blade storage box 1 described in the embodiment. Figures 1 to 11 The differences between the blade storage box 1 in this third embodiment and the previous one will be explained. Specifically, the main difference in the blade storage box 1 of this third embodiment lies in the angle α between the surface of the first arm 30421 facing away from the second arm 30422 and the surface 30411 of the body 3041. Figures 1 to 11 In one embodiment, the angle α between the surface of the first arm 30421 facing away from the second arm 30422 and the surface 30411 of the body 3041 is greater than 90°; in the third embodiment, the angle α between the surface of the first arm 30421 facing away from the second arm 30422 and the surface 30411 of the body 3041 is less than or equal to 90°.

[0081] The above is a detailed description of several exemplary embodiments of the blade storage box 1 of this application. The following will provide an exemplary description of the installation and use process of the blade storage box 1 proposed in this application.

[0082] Combined with appendix Figures 1 to 11 The installation and use process of the blade storage box 1 proposed in this application is as follows.

[0083] The damping element 304 is installed in the receiving cavity 308 of the button 30, wherein the damping arm 3042 does not contact the receiving cavity 308 of the button 30, and then the button 30 is installed in the housing 10.

[0084] The stacked blades 2 are installed into the housing 10, followed by the installation of the base plate 20. At this point, the elastic element 40 on the base plate 20 applies an upward elastic force to the blades 2 towards the button 30, thereby retracting the blades 2 between the button 30 and the elastic element 40. The button 30 is in the first position, and the damping element 304 contacts the blades 2. (See [reference needed]). Figure 2 .

[0085] When blade 2 is required, please refer to [link / reference]. Figure 3 An external force pushes button 30 to the second position, and the protrusion 303 at the free end of the hook portion 302 of button 30 hooks the blade 2, keeping the compression spring 307 compressed. Then the external force is removed, and button 30 moves back to the first position under the elastic force of the compression spring 307. (See [link]). Figure 4 and Figure 5 This causes the hook part 302 to eject the hooked blade 2 from the slit 301. During this process, the force applied by the blade 2 to the damping member 304 causes the second arm 30422 of the damping member 304 to swing clockwise relative to the first arm 30421, thereby increasing the contact area between the damping member 304 and the blade 2 and preventing the blade 2 from ejecting at high speed.

[0086] When the ejected blade 2 needs to be retracted, an external force pushes the blade 2 into the storage box 1. At this time, the force applied by the blade 2 to the damping member 304 can cause the second arm 30422 of the damping member 304 to swing counterclockwise relative to the first arm 30421, thereby reducing the contact area between the damping member 304 and the blade 2 and avoiding difficulty in retracting the blade 2.

[0087] In summary, the blade storage box proposed in this application includes a box body, a base plate, a button, an elastic element, several blades, and a damping element. The box body has a notch. The base plate is connected to the box body and defines a cavity with the box body. The button is disposed in the notch, and there is a slit between the button and the side wall of the box body for the blade to pass through. The button has a hook portion extending into the cavity, and the free end of the hook portion is used to hook the blade and eject the blade from the blade storage box through the slit. The elastic element is disposed in the base plate and provides an elastic force toward the button. Several blades are stacked and located between the elastic element and the button. The damping element is disposed in the button and contacts the blade. The damping force of the damping element can be changed according to the different movement directions of the blade. When the blade is ejected from the storage box at high speed, the surface of the blade in contact with the damping element slides relative to the damping element, so that the damping element can apply a damping force opposite to the movement direction of the blade to the surface of the blade. This reduces the ejection speed of the blade, avoids user injury or other accidental injuries, and does not make it difficult to retract the blade due to the setting of the damping element.
