Abstract

This utility model discloses a pen, including a shell, an unlocking component, a first resetting component, and a pen refill. The shell has a receiving cavity, and its upper and lower ends each have a first opening and a second opening matching the pen tip, respectively. The side wall of the shell has an installation port. The outer side wall of the pen refill has a locking part matching the unlocking component. The unlocking component rotates relative to the shell, thereby locking or unlocking the unlocking component and the locking part. When the unlocking component and the locking part are locked, the shell, the unlocking component, and the locking part are locked together.

The upper and lower ends of the outer casing 10 are respectively provided with a first opening 101 and a second opening 102 that matches the pen tip 42. Both the first opening 101 and the second opening 102 are connected to the receiving cavity.

[0035] The pen refill 40 is inserted into the receiving cavity through the first opening 101. The first reset member 30 is connected to the outer shell 10 and the pen refill 40 respectively, and the first reset member 30 causes the pen refill 40 to tend to move away from the outer shell 10.

[0036] The outer shell 10 and the pen refill 40 are detachably connected, thereby enabling the locking and unlocking of the outer shell 10 and the pen refill 40. When the outer shell 10 and the pen refill 40 are unlocked, the first reset member 30 drives the pen refill 40 to move in a direction away from the outer shell 10.

[0037] When this pen is in use, once the pen tip 40 is used up, simply operate the detachable housing 10 and pen tip 40 to unlock. At this time, the first reset member 30 drives the pen tip 40 to move away from the housing 10, and inserts the new pen tip 40 into the receiving cavity through the first opening 101, thereby locking the housing 10 and pen tip 40 and completing the replacement of the pen tip 40.

[0038] Compared with traditional pens, this new type of pen allows for easy replacement of the refill 40 without disassembling the outer casing 10 after the refill 40 is used up, making it more convenient to use.

[0039] Preferably, in this embodiment, the pen also includes an unlocking component 20, and the side wall of the outer casing 10 is provided with an installation port 103 communicating with the receiving cavity, and the unlocking component 20 is rotatably disposed in the installation port 103.

[0040] The outer wall of the pen refill 40 is provided with a locking part 44 that matches the unlocking member 20. The unlocking member 20 rotates relative to the housing 10, thereby locking or unlocking the unlocking member 20 and the locking part 44. When the unlocking member 20 and the locking part 44 are locked, the housing 10, the unlocking member 20 and the locking part 44 are locked together. When the unlocking member 20 and the locking part 44 are unlocked, the first reset member 30 drives the pen refill 40 to move in a direction away from the housing 10.

[0041] In this embodiment, the outer shell 10 and the pen refill 40 are detachably connected by the unlocking member 20 provided at the mounting port 103.

[0042] In other embodiments, the housing 10 and the pen refill 40 may also be detachably connected in other ways, such as by snap-fit, threaded connection, interference fit, etc.

[0043] At this time, when the pen refill 40 is used up, simply operate the unlocking member 20 to rotate relative to the outer shell 10, so that the unlocking member 20 and the locking part 44 are unlocked, thereby unlocking the outer shell 10 and the pen refill 40. At this time, the first reset member 30 drives the pen refill 40 to move in a direction away from the outer shell 10, and inserts the new pen refill 40 into the receiving cavity again through the first opening 101, so that the unlocking member 20 and the locking part 44 are locked together, and the outer shell 10, the unlocking member 20 and the locking part 44 are locked together, completing the replacement of the pen refill 40.

[0044] Preferably, in this embodiment, the unlocking member 20 includes a locking engagement part 22, a rotating part 24, and an operating part 26 connected in sequence.

[0048] In other embodiments, the locking part 44 may be configured as a locking block, and the locking engagement part 22 may be configured as a locking groove.

[0049] Referring to the accompanying drawings, in this embodiment, the first reset member 30 is a spring sleeved on the outside of the pen refill 40. After the pen refill 40 is inserted into the receiving cavity through the first opening 101, the first reset member 30 is elastically compressed, thereby causing the pen refill 40 to tend to move away from the outer shell 10.

[0050] In other embodiments, the first reset member 30 may also be other elastic structures or two mutually repulsive magnets.

[0051] Preferably, in this embodiment, the pen further includes a second reset member 50, which is connected to the housing 10 and the operation part 26 respectively, and the second reset member 50 causes the locking engagement part 22 to tend to move closer to the locking part 44.

[0052] More preferably, in this embodiment, the second reset member 50 is a spring. After compression, the second reset member 50 is connected to the end of the locking engagement part 22 away from the rotating part 24. The end of the locking engagement part 22 away from the rotating part 24 is used to snap-fit ​​with the locking part 44.

[0053] In other embodiments, the second reset member 50 may also be other elastic structures or two mutually repulsive magnets.

[0054] Preferably, in this embodiment, the outer side of the outer shell 10 is provided with a receiving groove 104 communicating with the mounting port 103, and the second reset member 50, the rotating part 24 and the operating part 26 are disposed in the receiving groove 104.

[0055] Preferably, in this embodiment, the locking part 44 is annular. The annular locking part 44 ensures that the pen refill 40 can be inserted into the receiving cavity from the first opening 101 at any angle, while still achieving the locking of the unlocking member 20 and the locking part 44.

[0056] Specifically, referring to the accompanying drawings, in this embodiment, the locking part 44 is an annular groove.

[0057] Specifically, referring to the accompanying drawings, in this embodiment, the end of the locking part 22 away from the rotating part 24 is an arc shape that matches the locking part 44.

[0058] Preferably, in this embodiment, the upward-facing side of the locking engagement part 22 away from the rotating part 24 and / or the downward-facing side of the locking part 44 are curved or arc-shaped surfaces.

[0059] The side of the locking engagement part 22 facing upward away from the rotating part 24 and / or the side of the locking part 44 facing downward are curved or arc-shaped, which makes it easier for the pen refill 40 to be inserted into the receiving cavity through the first opening 101, thereby achieving the locking of the unlocking part 20 and the locking part 44.

The interior of the cylindrical pressing member 14 and the interior of the cylindrical body 12 together form a receiving cavity. The pen tip 42 of the pen refill 40 passes through the cylindrical pressing member 14 and is inserted into the cylindrical body 12.

[0063] The press-and-extend assembly is located between the upper end of the cylindrical press member 14 and the cylindrical body 12. The cylindrical body 12, the cylindrical press member 14, the press-and-extend assembly and the first reset member 30 work together to realize the press-and-extend of the pen refill 40.

[0064] Combination Figure 5 In this embodiment, the cylindrical pressing member 14 is slidably sleeved on the upper end of the cylindrical body 12. The pressing telescopic assembly includes a driving block 16 disposed on the outer side of the upper end of the cylindrical body 12 and a pressing telescopic structure 18 disposed on the inner side of the cylindrical pressing member 14.
