Description

Technical Field

[0001] This utility model relates to a portable safety box opener with replaceable blades, belonging to the technical field of box openers. Background Technology

[0002] A box opener is a tool used to open various boxes and cartons, and it is widely used in daily life, logistics, warehousing, and many other fields. Currently, the blades of traditional box openers are mostly fixed in place. When the blades wear out or are damaged, they are difficult to remove and replace individually, rendering the entire box opener unusable. This necessitates replacing the entire box opener, which not only wastes resources but also increases operating costs.

[0003] To address this, in the prior art, Chinese utility model patent application number CN202022385695.3 discloses a box opener that detachably mounts a pointed cone for opening boxes onto a mounting post via a threaded connection. This allows for easy replacement of the cone when it wears or is damaged, thereby reducing operating costs. However, the threaded connection method has the drawback of requiring a long time for assembly and disassembly, and there is also a risk of being punctured by the cone when screwing it in or out. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a portable safety box opener with replaceable blades.

[0005] The technical solution of this utility model is as follows:

[0006] A portable safety box opener with replaceable blades includes a handle portion, a mounting portion with a mounting cavity, a movable block rotatably connected to the mounting cavity via a rotating shaft, a blade portion being engaged with the mounting portion, the bottom of the blade portion abutting against one end of the movable block, and a pressure rod movably passing through the mounting portion via a connecting channel, the connecting channel being connected to the mounting cavity, the end of the pressure rod penetrating the mounting portion abutting against the other end of the movable block.

[0007] The mounting part is provided with a placement groove and a connecting groove, both of which are connected to the mounting cavity. The placement groove is adapted to the blade part, which is located in the placement groove. The connecting groove is located below the placement groove and has a snap-fit ​​block. The bottom of the blade part has a connecting part, which penetrates into the mounting cavity and abuts against the movable block. A snap-fit ​​groove is provided on the side wall of the connecting part near the snap-fit ​​block. When the connecting part abuts against the movable block, the snap-fit ​​block snaps into the snap-fit ​​groove.

[0008] The handle portion has a through-hole.

[0009] The blades on the blade section are arranged at an angle.

[0010] This utility model has the following beneficial effects:

[0011] This invention features an installation section with an installation cavity, a rotating shaft, a movable block, a connecting channel, and a pressure rod. The blade is snapped into the installation section. When the blade needs replacement due to wear, the operator inserts the pressure rod into the connecting channel, making it abut against one end of the movable block. Pressing the movable block downwards causes it to rotate around the rotating shaft, lifting the end of the movable block away from the pressure rod and pushing the blade out of the installation section. The operator then removes the pressure rod and snaps a new blade into the installation section, completing the blade replacement. Compared to existing technologies, this snap-fit ​​method replaces threaded connections, resulting in quick assembly and disassembly with less risk of injury from the blade. It offers advantages such as ease of use and high safety. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example: Please refer to Figures 1-4This embodiment provides a portable safety case opener with replaceable blades, including a handle part 1. A mounting part 2 is provided on the right end of the handle part 1. The handle part 1 can be secured to the mounting part 2 by opening a corresponding slot, allowing it to engage with the handle part 1 for subsequent replacement operations. Alternatively, it can be fixed to the handle part 1 using adhesive or other methods. The mounting part 2 has a mounting cavity 3. A movable block 5 is rotatably connected to the mounting cavity 3 via a rotating shaft 4. The rotating shaft 4 is horizontally positioned within the mounting cavity 3, and its connection to the movable block 5 is located slightly to the left of the movable block 5, facilitating the lever action of the movable block 5 to pry up the required component.

[0020] The mounting part 2 is fitted with a blade part 6. In this embodiment, the mounting part 2 has a placement groove 9 and a connecting groove 10. Both the placement groove 9 and the connecting groove 10 are connected to the mounting cavity 3. The placement groove 9 is adapted to the blade part 6 so that the blade part 6 can be placed into the placement groove 9. The connecting groove 10 is located below the placement groove 9 and is also connected to the placement groove 9. A vertically arranged locking block 11 is provided in the connecting groove 10. The bottom of the locking block 11 is fixedly connected to the bottom wall of the connecting groove 10. The top of the locking block 11 is provided with an arc-shaped protrusion near the side wall of the blade part 6. A connecting part 12 is fixedly provided at the bottom of the blade part 6. After the bottom of the connecting part 12 passes into the mounting cavity 3, it abuts against the top of the right end of the movable block 5. The bottom of the blade part 6 can abut against the right end of the movable block 5 through the setting of the connecting block. A snap-fit ​​groove 13 is opened on the side wall of the connecting part 12 close to the snap-fit ​​block 11. When the blade part 6 is placed in the placement groove 9 and the connecting part 12 abuts against the movable block 5, the arc-shaped protrusion structure at the top of the snap-fit ​​block 11 can snap into the snap-fit ​​groove 13, thereby realizing the snap-fit ​​between the blade part 6 and the mounting part 2, so as to fix the blade part 6 on the mounting part 2. A pressure rod 8 is also movably passed through the mounting part 2 through a connecting channel 7. The connecting channel 7 is connected to the mounting cavity 3. The end of the pressure rod 8 that passes into the mounting part 2 can abut against the top of the left end of the movable block 5.

[0021] With the aforementioned setup, when the blade on the blade section 6 needs replacement due to wear, the operator inserts the pressure rod 8 into the connecting channel 7 and abuts it against the top of the left end of the movable block 5. Then, the operator continues to press the movable block 5 downwards, causing it to undergo a lever motion around the rotating shaft 4. At this time, the right end of the movable block 5 applies a pushing force to the connecting part 12, allowing it to move upwards. This causes the locking block 11 to deform and disengage from the locking groove 13. The movable block 5 can pry the blade part 6 out of the mounting part 2, thereby completing the disassembly of the blade part 6. Then, the operator pulls out the pressure rod 8, takes out the new blade part 6 and places it into the placement groove 9, and presses the blade part 6 downward so that the connecting part 12 enters the connecting groove 10, and makes the arc-shaped protrusion on the top of the snap-fit ​​block 11 snap into the snap-fit ​​groove 13 on the connecting part 12. At this time, the connection of the snap-fit ​​block 11 and the snap-fit ​​groove 13 can fix the blade part 6 on the mounting part 2, thus completing the replacement of the blade part 6.

[0022] To facilitate use by staff, in this embodiment, a through-hole 14 is provided on the handle 1. Through the through-hole 14, staff can grip the handle 1 for easy use of the case opener, and can also use the through-hole 14 to hang the case opener for easy carrying.

[0023] To make it easier for this box opener to open boxes, in this embodiment, the blade on the blade section 6 is set at an angle. The angled blade can more easily cut through adhesive tools such as tape.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
