[0002] As an indispensable traditional writing tool, pens are usually carried by people in need of one or more pens, whether for daily use or traveling. Ordinary pens usually use pen caps to protect the nibs. There is also a type of pen that has a press-type retractable nib to protect the nib from damage due to bumps, which is also very practical.

[0003] The existing push-telescopic writing pen is usually composed of a pen case, a pen core, a telescopic locking mechanism, a push cap and other components, wherein the telescopic locking mechanism is generally composed of a locking member, a pressure rod, a guide rail, a guide rail arranged on the inner side of the pen case and other components. By pressing the push cap at the rear end of the pen, the front end of the pen core can be driven to extend or retract toward the outside of the pen case, thereby realizing the switch between the writing state and the storage state. For example, Chinese patent: CN202321226889.6 Push-telescopic writing pen; Chinese patent CN202222610756.0 A multifunctional push-telescopic pen; the above two push-telescopic pens can well meet the energy supply of push-telescopic, but both are relatively complex in structure, so their production process is relatively cumbersome, and there are relatively more parts. In addition, this kind of pen will make a "clicking" sound during the pressing process, which is very unpleasant in a quiet learning environment. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] like Figure 1-8 The illustrated embodiment of a light-sound-pressed gel pen comprises a pen case 1 with a notch 11, a refill 2 and a side pressure switch 3, wherein the side pressure switch 3 comprises a boat-shaped pressing plate 31 protruding from the pen case 1 at the notch 11, a mounting block 33 fixedly engaged with the pen case 1, and a sliding block 32 disposed in the pen case 1 and abutting against the tail of the refill 2. A hinge shaft 311 is provided in the middle of the boat-shaped pressing plate 31 which is hinged relative to the pen case 1, and the sliding block 32 is driven to extend and retract relative to the pen case 1 by pressing with an external force.

[0023] As a further configuration of the above scheme, a hinged rod 312 is further provided on the ship-shaped pressing plate 31, and the hinged rod 312 is hingedly engaged with a sliding groove 326 provided on the sliding block 32. When the ship-shaped pressing plate 31 is pressed and swung by an external force, the hinged rod 312 drives the sliding block 32 to move up and down.

[0024] As a further configuration of the above scheme, the hinge shaft 311 is connected to the mounting block 33, and a cam structure 313 is provided on at least one side of the hinge shaft 311 of the ship-shaped pressing plate 31, and a positioning groove 331 is provided on the mounting block 33 corresponding to the cam structure 313, and the positioning groove 331 includes an upper groove 3311 and a lower groove 3312.

[0025] As a further configuration of the above solution, the positioning groove 331 is further extended with an elastic notch 333 , and the elastic notch 333 is used to provide an elastic expansion opening margin for the positioning groove 331 .

[0026] As a further configuration of the above scheme, an engaging block 335 is provided on the mounting block 33 and a limiting column 336 is provided on the other side of the mounting block 33 relative to the engaging block 335 , a corresponding engaging groove 337 is provided above the notch 11 and a limiting hole 338 is provided corresponding to the limiting column 336 .

[0027] As a further configuration of the above solution, the bottom of the sliding block 32 abuts against the pen core 2 , and a spring 7 for driving the pen core 2 to retract into the pen case 1 is provided on the pen core 2 and the pen case 1 .

[0028] As described above, the light sound pressing gel pen of the utility model, the gel pen of this embodiment comprises a pen case 1 with a notch 11, a refill 2 arranged in the pen case 1 and a side pressure switch 3, wherein the side pressure switch 3 is installed and arranged with the pen case 1 through the notch 11, and the side pressure switch 3 comprises a boat-shaped pressing plate 31 as a main finger pressing element protruding from the pen case 1 at the notch 11, a mounting block 33 for engaging and fixing with the pen case 1 to keep the components in the pen case 1 from detaching from the pen case 1, a sliding block 32 located in the pen case 1 and abutting against the tail of the refill 2, and having a main telescopic effect, and it is worth noting that The main structure of the design of this embodiment includes a hinge shaft 311 provided in the middle of the boat-shaped pressing plate 31 connected to the mounting block 33. Based on the axial engagement and fixation between the mounting block 33 and the pen housing 1, the hinge shaft 311 is hinged and rotated relative to the pen housing 1, and the hinge rod 312 provided on the boat-shaped pressing plate 31 moves up and down relative to the pen housing 1 while swinging, so that the boat-shaped pressing plate 31 is pressed by external force to drive the hinge rod 312 to move up and down, driving the sliding block 32 located inside the pen housing 1 to slide up and down relative to the pen housing 1, and driving the pen core 2 abutting against the sliding block 32 to extend and retract relative to the pen housing 1. The specific structure is as follows Figure 2-7 shown.

[0029] The hinged rod 312 provided on the boat-shaped pressing plate 31 of this embodiment is hingedly engaged with the sliding groove 326 provided on the sliding block 32, and the sliding groove 326 is slightly larger than the hinged rod 312, so that the hinged rod 312 can move in a non-axial direction of the pen shell 1 during the swinging process, thereby realizing that when the boat-shaped pressing plate 31 is pressed by external force and swings relative to the pen shell 1 based on the hinge shaft 311, the hinged rod 312 drives the sliding block 32 to move up and down relative to the pen shell 1.

[0030] The hinge shaft 311 of the present embodiment is hinged on the mounting block 33 on one side as shown in the figure, and a cam structure 313 is provided on the other side. It is worth noting that the purpose of the cam structure 313 of the present embodiment is to play a positioning and limiting role in the present utility model, so that when the boat-shaped pressing plate 31 is pressed by no external force, that is, the force transmitted from the side of the pen core 2 during the writing process, the sliding block 32 will not be pushed to move up and down, thereby realizing that the pen core 2 is stably extended and positioned and will not be retracted during the writing process. As shown in the figure, a positioning groove 331 is provided on the mounting block 33 of the present embodiment corresponding to the cam structure 313, and the positioning groove 331 includes an upper notch 3311 and a lower notch 3312. Figure 6 and Figure 7 As shown, during use, when the pen core 2 is extended, the cam structure 313 swings to the lower notch 3312 and remains based on pressing the boat-shaped pressing plate 31. When there is no active external force pressing the boat-shaped pressing plate 31, the cam structure 313 is stuck at the lower notch 3312, and the pen core 2 is stably extended for writing. After being pressed by external force, the cam structure 313 is driven to swing to the upper notch 3311, and the pen core 2 retracts. Furthermore, in order to ensure the smooth switching between the two, the positioning groove 331 of this embodiment is also extended to form an elastic notch 333, and the elastic notch 333 is used to provide an elastic expansion opening margin for the positioning groove 331. During use, the swing of the cam structure 313 will generate a stress on the mounting block 33, thereby causing the positioning groove 331 to expand. The elastic notch 333 is provided in this embodiment so that the positioning groove 331 has an expansion margin, thereby avoiding the cracking of the plastic caused by long-term forced expansion, which causes the mounting block 33 to be damaged.

[0031] As a further configuration of the above scheme, an embedding block 335 is provided on the mounting block 33 and a limiting post 336 is provided on the other side of the mounting block 33 opposite to the embedding block 335. A corresponding embedding groove 337 is provided above the notch 11 and a limiting hole 338 is provided corresponding to the limiting post 336. The mounting block 33 of this embodiment realizes axial limiting fixation of the mounting block 33 relative to the pen shell 1 through the embedding block 335 and the embedding groove 337. The top of the mounting block 33 is embedded in the upper end of the pen shell 1 for radial limiting, and the limiting post 336 with an inclined surface is inserted into the limiting hole 338 to provide further guarantee for the fixed embedding of the mounting block 33, so that it can be stably installed, and the cooperation between the embedding block 335 and the embedding groove 337 is locked. When disassembly is required, a tool is placed on the limiting post 336, and then the mounting block 33 is pushed upward to facilitate separation. Then the mounting block 33 can be removed, and the components inside the pen shell 1 can be poured out.

[0032] As a further configuration of the above scheme, the bottom of the sliding block 32 abuts against the pen core 2, and a spring 7 for driving the pen core 2 to retract into the pen shell 1 is provided on the pen core 2 and the pen shell 1. The spring 7 is used to automatically retract the pen core 2, which is a conventional configuration. On the basis of this embodiment, a further design can be made to directly fix the pen core 2 and the sliding block 32, so that when the sliding block 32 is extended and retracted up and down, the pen core 2 is also driven to directly retract and retract.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
