Description

Technical Field

[0001] This technical solution relates to the field of cutting tool technology, specifically a box opener. Background Technology

[0002] A box opener is a tool used to open packaging materials such as boxes and cartons.

[0003] For example, Chinese patent CN202322019671.X discloses a box opener, which includes a blade, a handle unit, a blade head unit, and a spring unit. When in use, you only need to press the blade head at the place to be cut to make the blade automatically exposed for cutting. After use, the blade head automatically resets and covers the blade again, so that the blade will not be easily exposed and cause injury.

[0004] These types of box cutters have the drawback of being single-function, equipped with only a single blade for cutting, making them inconvenient to use. For example, while you can use a box cutter to cut tape when opening a package, the waybill contains personal information. To prevent the leakage of personal information when throwing away the package, you need to use a marker to cover up the information on the waybill after opening the package. This results in the need to use multiple tools, which are not only easy to lose, but also inconvenient to carry when going out, and you need to find the corresponding parts when using them. Utility Model Content

[0005] The purpose of this technical solution is to provide a box opener that improves the problem of the single function of existing box openers by sequentially setting a first mounting cavity and a second mounting cavity inside the outer shell, with a cutting tool device installed in the first mounting cavity and a marker pen device installed in the second mounting cavity.

[0006] The purpose of this technical solution is achieved as follows:

[0016] A driving component is slidably disposed on the housing, and the driving component extends into the mounting cavity through the strip hole of the housing and is connected to the blade;

[0017] By driving the drive member to slide within the strip hole, the drive member causes the blade to slide within the mounting cavity, thereby enabling the blade to extend or retract relative to the mounting cavity.

[0018] Preferably, the front end of the outer shell is provided with a strip-shaped hole along its length, and a limit groove is provided on the side wall of the strip-shaped hole;

[0019] The driving component can be engaged or disengaged from the limiting groove;

[0022] Preferably, the driving component includes a driving part, a sliding part, and an abutting part. The driving part is located on the outside of the housing, the sliding part is slidably disposed in the strip-shaped hole, and the abutting part is located in the mounting cavity and connected to a driving seat. The rear end of the blade is fixed on the driving seat through the abutting part.

[0023] At least one fixing post is provided on the drive seat or the abutment part, and at least one fixing hole corresponding to the fixing post is provided at the rear end of the blade, and the fixing post is inserted into the corresponding fixing hole.

[0024] Preferably, the front end of the blade is provided with a first blade and a second blade on opposite sides, and the second blade has a serrated structure.

[0025] Preferably, the upper end of the outer shell is provided with an installation port, the installation port is snapped with a cover, the cover is provided with an installation groove, and a magnetic suction element is provided in the installation groove.

[0026] Preferably, a limiting opening is provided on the side wall of the second mounting cavity, and the limiting opening passes through the cavity opening of the second mounting cavity;

[0047] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-8 .

[0048] Example 1:

[0049] A box opener includes:

[0050] The outer casing 1 has a first mounting cavity 11 and a second mounting cavity 12, and the first mounting cavity 11 is located on the side of the second mounting cavity 12, that is, the first mounting cavity 11 and the second mounting cavity 12 are distributed on the left and right sides inside the outer casing 1.

[0051] The cutting tool device 2 is installed in the mounting cavity 11, and the blade 21 of the cutting tool device 2 can extend out of the mounting cavity 11. By controlling the blade 21 to extend or retract relative to the mounting cavity 11, the cutting tool device 2 can cut or store items.

[0052] The marker pen device 3 is detachably installed in the mounting cavity 12 and can be used by removing the marker pen device 3.

[0053] The outer casing 1 houses two modules: a knife device 2 and a marker device 3. This design facilitates portability and use, prevents the loss of individual modules, and enhances the versatility of functions.

[0054] The side wall of the outer shell 1 is provided with a notch 13, which connects the mounting cavity 11 to the outside. The notch 13 penetrates the front end, side end and rear end face of the outer shell 1. The blade 212 of the blade 21 is movably placed at the notch 13.

[0055] When cutting rope-like items, the object to be cut is placed into the notch 13, and the blade 21's first edge 212 cuts the object. This prevents the first edge 212 from protruding outside the notch 13 and cutting the user. Cutting can be achieved simply by placing the object into the notch 13, without any other steps, thus improving cutting efficiency and making it safe and convenient.

[0056] The two opposite sidewalls of the notch 13 are obliquely cut towards the direction in which the blade 21 extends out of the mounting cavity 11. The oblique cutting of the sidewalls of the notch 13 makes it easy for the object to be cut to be placed in the notch 13, and the object to be cut slides along the sidewall of the notch 13 toward the blade 212, which facilitates the cutting of the blade 21 and improves the cutting efficiency and cutting effect.

[0057] An opening 14 is provided at the bottom of the outer casing 1, and a strip-shaped hole 15 is provided on the front end face of the outer casing 1;

[0058] The cutting tool device 2 includes:

[0059] The blade 21 is slidably disposed in the mounting cavity 11, and the front end of the blade 21 can extend out of the mounting cavity 11 through the opening 14 of the housing 1.

[0060] The driving component 22 is slidably disposed on the housing 1, and the driving component 22 extends into the mounting cavity 11 through the strip hole 15 of the housing 1 and is connected to the blade 21.

[0061] Driven by external force, the drive component 22 slides within the slotted hole 15, causing the drive component 22 to drive the blade 21 to slide within the mounting cavity 11, thereby enabling the blade 21 to extend or retract relative to the mounting cavity 11. This allows the blade 21 to extend for cutting or retract into the mounting cavity 11 to avoid scratching the user.

[0062] The front end of the outer casing 1 is provided with a strip-shaped hole 15 along its length direction, and a limit groove 151 is provided on the side wall of the strip-shaped hole 15.

[0063] The drive component 22 can engage or disengage from the limiting groove 151; when the drive component 22 engages with the limiting groove 151, the blade 21 is kept inside the mounting cavity 11 to prevent the blade 21 from accidentally extending and scratching the user.

[0064] At least one limiting groove 152 is provided on the side wall of the strip hole 15. The limiting groove 151 and the limiting groove 152 are arranged sequentially along the length direction of the strip hole 15, and the limiting groove 152 is closer to the opening 14 than the limiting groove 151. The driving member 22 is engaged with or disengaged from the limiting groove 152.

[0065] In this embodiment, two limiting grooves 152 are provided. When the driving member 22 is engaged with the limiting groove 152 located near the limiting groove 151, the distance of the front end of the blade 21 can ensure that the tape on the carton is cut without scratching the items inside the carton. When the driving member 22 is engaged with the limiting groove 152 located away from the limiting groove 151, the front end of the blade 21 can be fully extended out of the mounting cavity 11.

[0066] The driving component 22 includes an integrally formed driving part 221, a sliding part 222, and an abutting part 223. The driving part 221 is located on the outside of the housing 1 and is used for pressing and pushing by the user. The sliding part 222 is slidably disposed in the strip hole 15. The two ends of the sliding part 222 are respectively connected to the driving part 221 and the abutting part 223. The abutting part 223 is placed in the mounting cavity 11 and connected to the driving seat 23. The abutting part 223 is engaged with the locking hole 232 of the driving seat 23 through the buckle 224. The rear end of the blade 21 is fixed on the driving seat 23 through the abutting part 223, so that the blade 21 is installed on the driving component 22.

[0067] The rear end of the blade 21 is fixed to the drive seat 23 by the abutment part 223. Specifically, the lower end of the abutment part 223 and the upper end of the blade 21 can be glued together, and the upper end of the drive seat 23 and the lower end of the blade 21 can be glued together. Alternatively, after the abutment part 223 and the drive seat 23 are engaged, there is a clamping space between the abutment part 223 and the drive seat 23 for the rear end of the blade 21 to be inserted. The blade 21 is fixed by the clamping force between the abutment part 223 and the drive seat 23.

[0068] Alternatively, this technical solution employs at least one fixing post 231 on the drive seat 23 or the abutment part 223, and at least one fixing hole 211 corresponding to the fixing post 231 is provided at the rear end of the blade 21. The fixing post 231 is inserted into the corresponding fixing hole 211, and the abutment part 223 is placed above the fixing post 231 to prevent the blade 21 from falling off the fixing post 231, that is, to prevent the blade 21 from detaching from the drive seat 23 or the abutment part 223. The number of fixing posts 231 can be set to multiple, thereby ensuring that the blade 21 is more stable after installation and preventing the blade 21 from moving. In this embodiment, a fixing post 231 is provided on the drive seat 23. When the fixing post 231 is inserted into the fixing hole 211, the rotation limiting part 214 of the blade 21 abuts against the front end of the side wall of the drive seat 23, and the rear end side wall of the blade 21 abuts against the side end of the side wall of the drive seat 23, thereby restricting the rotation of the blade 21 on the drive seat 23.

[0069] The sliding part 222 is provided with a snap-fit ​​protrusion and a connecting strip on its side wall. The snap-fit ​​protrusion can snap into the second limiting groove 152 or the first limiting groove 151. When the driving member 22 moves under external force, the connecting strip can undergo elastic deformation to ensure that the snap-fit ​​protrusion disengages from the second limiting groove 152 or the first limiting groove 151. The elastic snap-fit ​​protrusion is connected to the side wall of the sliding part 222 by the connecting strip. Both sides of the snap-fit ​​protrusion have guide surfaces or the snap-fit ​​protrusion is a hemisphere, thereby guiding the snap-fit ​​protrusion to slide at the opening of the second limiting groove 152 or the first limiting groove 151 and disengage from the second limiting groove 152 or the first limiting groove 151.

[0070] The front end of the blade 21 has two opposing blades, one blade 212 and the other blade 213. Blade one 212 is a flat blade, and blade two 213 is a serrated structure, that is, blade two 213 is a serrated blade.

[0071] The upper end of the outer shell 1 is provided with an installation port 16, and the installation port 16 is snapped into the cover 4. The cover 4 is provided with an installation groove 41, and a magnetic suction element 5 is provided in the installation groove 41. The magnetic suction element 5 is a magnet, and the outer shell 1 is attracted to a magnetic metal surface by the magnetic force of the magnetic suction element 5.

[0072] The cover 4 is provided with a limiting protrusion 42, and the strip hole 15 passes through the rear end of the mounting cavity 11. When the cover 4 is snapped into the mounting opening 16, the limiting protrusion 42 is placed in the strip hole 15.

[0073] A limiting port 17 is provided on the side wall of the second mounting cavity 12. The limiting port 17 passes through the cavity opening of the second mounting cavity 12, that is, the limiting port 17 passes through the end of the second mounting cavity 12.

[0074] The marker device 3 includes:

[0075] The marker pen body 31 is detachably installed in the mounting cavity 2 12, and a limiting part 32 is provided on the rear side wall of the marker pen body 31.

[0076] When the rear end of the marker body 31 is engaged with the mounting cavity 2 12, the limiting part 32 is placed inside the limiting opening 17, and the front end of the marker body 31 can be located on the outside or inside of the mounting cavity 2 12.

[0077] When the marker pen device 3 is in the storage state, the front end of the marker pen body 31 is first inserted into the second mounting cavity 12, and then the limiting part 32 at the rear end of the marker pen body 31 is inserted into the limiting port 17. At this time, the front end of the marker pen body 31 is located inside the second mounting cavity 12.

[0078] When the marker pen device 3 is in use, by taking out the marker pen body 31, the rear end of the marker pen body 31 is inserted into the mounting cavity 2 12, and the limiting part 32 is inserted into the limiting port 17. At this time, the front end of the marker pen body 31 is located outside the mounting cavity 2 12, and the outer shell 1 can serve as the pen body for the user to hold. In practice, the marker pen body 31 can also be used independently.

[0079] The outer casing 1 is provided with an opening 18, which is used to insert ropes, keychains, or buckles for easy hanging and carrying.

[0080] Example 2:

[0081] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0082] The sidewall of the strip hole 15 does not have a limiting groove 151 and a limiting groove 152. The driving component 22 is slidably disposed in the strip hole 15. The driving component 22 is maintained in the set state and position by the friction between the driving component 22 and the strip hole 15 or by the external force applied to the driving component 22 by the user.

[0083] Example 3:

[0084] The design scheme of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2, except that:

[0085] A U-shaped groove is provided in the mounting cavity 11. The front end of the U-shaped groove is connected to the opening 14. The blade 21 is parallel to the bottom of the groove and is slidably disposed in the U-shaped groove. The U-shaped groove can ensure that the front end of the blade 21 extends out of the mounting cavity 11 through the opening 14.
