Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and more particularly to a structurally stable pen lamp. Background Technology

[0002] In daily life, pens and lamps are common objects, each performing its own function to serve people's work and life.

[0003] However, in existing pen lights, the on / off state and pen tip extension are usually controlled by a sliding switch. When the pen light is dropped, the sliding switch is prone to moving out of its original position, causing damage to the internal components of the pen light. Summary of the Invention

[0004] In view of the above, it is necessary to propose a structurally stable pen lamp that can solve the problem of damage to internal components when the pen lamp is dropped.

[0005] This application provides a structurally stable pen light, including a pen shell, a tail assembly, and a control assembly. The pen shell has a positioning groove, and the control assembly includes a slider and a lever. The slider is located inside the pen shell, and the lever passes through the slider and the positioning groove. The lever is used to drive the slider to move within the pen shell to activate the lighting switch in the tail assembly. The lever and the slider are telescopically connected, and the telescopic direction is perpendicular to the axis of the pen shell, so that when the lever is engaged in the positioning groove, it retracts relative to the slider, and when the lever is separated from the positioning groove, it extends relative to the slider.

[0006] Thus, by setting the lever and the slider to be telescopically connected with the telescopic direction perpendicular to the pen shell axis, the lever retracts relative to the slider when it is engaged in the positioning groove, and extends relative to the slider when the lever is separated from the positioning groove. This ensures that the lighting device can only be switched on and off by sliding along the pen shell axis when the lever is separated from the positioning groove, preventing the lever from shifting and damaging internal components when the pen light is dropped.

[0007] In some embodiments, a pen refill is provided inside the pen casing, and a first elastic element is provided at the end of the pen refill away from the tail assembly. The sliding switch moves in a direction away from the tail assembly and pushes the pen refill to squeeze the first elastic element so that the pen refill extends out of the pen casing.

[0008] Thus, by having a refill inside the pen casing, with a first elastic element at the end of the refill away from the tail assembly, the sliding switch moves away from the tail assembly and pushes the refill to squeeze the first elastic element, causing the refill to extend out of the pen casing. When the sliding switch moves in the opposite direction, it can control both the lighting device and the refill's ejection, making operation convenient. Simultaneously, the positioning groove prevents the refill from bursting out of the pen casing and damaging the pen tip if the pen light is dropped.

[0009] In some embodiments, the slider is provided with a limiting hole, the axis of which is perpendicular to the axis of the slider, and the lever passes through the limiting hole.

[0010] Thus, by providing a limiting hole in the slider, with the axis of the limiting hole perpendicular to the axis of the slider, and the lever passing through the limiting hole, the lever is prevented from separating from the slider when it drives the slider to move, making the movement of the slider by the lever more stable.

[0011] In some embodiments, a second elastic element is provided in the limiting hole for ejecting the lever from the sliding element when the lever is separated from the positioning groove.

[0012] Thus, by providing a second elastic element in the limiting hole, the lever is ejected from the sliding element when it separates from the positioning groove, allowing the lever to rise rapidly when it separates from the positioning groove for user control, thereby improving the user experience.

[0013] In some embodiments, a limiting rib is provided in the limiting hole, and an abutment is provided at the bottom of the lever. When the lever is separated from the positioning groove, the abutment abuts against the limiting rib to prevent the lever from disengaging from the sliding member.

[0014] Thus, by providing a limiting rib in the limiting hole and an abutment at the bottom of the lever, the abutment abuts against the limiting rib when the lever separates from the positioning groove, preventing the lever from detaching from the sliding part. This ensures that when the lever separates from the positioning groove, the lever will not completely detach from the sliding part, thus preventing the loss or damage of parts.

[0015] In some embodiments, a limiting sleeve is provided at the position of the lever near the positioning groove. The limiting sleeve is used to engage or disengage with the positioning groove, and a second elastic element is provided between the limiting sleeve and the limiting rib.

[0016] Thus, by providing a limiting sleeve at the position of the lever near the positioning groove, the limiting sleeve is used to engage or disengage with the positioning groove. The second elastic element is provided between the limiting sleeve and the limiting rib, so that the limiting sleeve limits the lever to be below the positioning groove, further preventing the lever from separating from the positioning groove when the pen light falls.

[0017] In some embodiments, the pen shell is provided with a limiting groove, a positioning groove is provided in the limiting groove, and the end of the lever is provided through the limiting groove so that when the lever moves along the limiting groove, it drives the sliding member to move.

[0018] Thus, by providing a limiting groove in the pen casing, the end of the lever passes through the limiting groove, so that when the lever moves along the limiting groove, it drives the sliding component to move, allowing the lever to slide within the limiting groove and preventing it from exceeding the preset travel distance. This would otherwise damage the lighting switch.

[0019] In some embodiments, the end of the lever is provided with a limiting part, which is used to limit the lever in the limiting groove in a direction perpendicular to the axis of the pen shell.

[0020] Thus, by providing a limiting part at the end of the lever, the limiting part is used to limit the lever in the limiting groove in a direction perpendicular to the axis of the pen shell, preventing the lever from falling into the limiting hole and thus preventing the sliding component from being controlled by the lever, thereby ensuring the stability of the lever.

[0021] In some embodiments, the end of the slider facing the pen refill forms a limiting cavity, and the end of the pen refill is disposed within the limiting cavity.

[0022] Thus, by forming a limiting cavity at the end of the slider facing the pen refill, and with the end of the pen refill located within the limiting cavity, the connection between the pen refill and the slider becomes more stable and reliable, and the slider will not deviate from the pen refill when it pushes the pen refill out.

[0023] In some embodiments, the control component further includes an impact plate disposed inside the pen housing and located between the slider and the lighting switch, wherein the impact plate is pushed toward the lighting switch when the slider slides toward the lighting switch.

[0024] Thus, by setting the control component, an impact plate is also included. The impact plate is located inside the pen shell and between the slider and the lighting switch. When the slider slides toward the lighting switch, it pushes the impact plate toward the lighting switch, so that the lever drives the slider to slide toward the lighting switch inside the pen shell until the slider abuts against the impact plate. Then the slider pushes the impact plate to touch the lighting switch, realizing the switching of the lighting device. This makes the lighting switch evenly stressed when it is touched, preventing uneven stress on the lighting switch and thus preventing damage, and extending the service life of the lighting switch.

[0025] In some embodiments, the slider has a baffle perpendicular to the slider axis inside, and the surface of the impact plate facing the slider is connected to the impact column. When the slider moves toward the lighting switch, the baffle abuts against the end of the impact column to push the impact column and the impact plate to move.

[0026] Thus, by providing a baffle perpendicular to the axis of the slider inside the slider, and the impact plate connected to the impact column on the surface of the slider, when the slider moves toward the lighting switch, the baffle abuts against the end of the impact column to push the impact column and the impact plate to move. When the lever drives the slider to move toward the lighting switch, the baffle in the slider abuts against the impact column and pushes the impact plate toward the lighting switch, thereby increasing the contact area between the slider and the impact plate and making the movement of the impact plate more stable and reliable.

[0044] Please see Figures 1 to 6 This application provides a structurally stable pen lamp, including a pen shell 100, a tail assembly 200, and a control assembly 300. The pen shell 100 is provided with a positioning groove 140. The control assembly 300 includes a slider 311 and a lever 312. The slider 311 is disposed inside the pen shell 100, and the lever 312 passes through the slider 311 and the positioning groove 140. The lever 312 is used to drive the slider 311 to move within the pen shell 100 to activate the lighting switch 210 in the tail assembly 200. The lever 312 and the slider 311 are telescopically connected, and the telescopic direction is perpendicular to the axis of the pen shell 100, so that when the lever 312 is engaged in the positioning groove 140, it retracts relative to the slider 311, and when the lever 312 is separated from the positioning groove 140, it extends relative to the slider 311.

[0045] The pen casing 100 contains a pen core 120. The end of the pen core 120 away from the tail assembly 200 is provided with a first elastic element 130. The sliding switch 310 moves in the direction away from the tail assembly 200 and pushes the pen core 120 to squeeze the first elastic element 130 so that the pen core 120 extends out of the pen casing 100.

[0046] The slider 311 slides toward the lighting switch 210, which can push the impact plate 320 to control the opening and closing of the lighting device 230. When the slider 311 slides toward the pen tip, it pushes the pen refill 120 to compress the first elastic member 130. It can be understood that the first elastic member 130 is a spring, with one end of the spring abutting against the pen tip and the other end abutting against the end of the pen refill 120. The pen refill 120 is pushed by the slider 311 to compress the spring until it extends out of the pen tip. At this time, the end of the limiting groove 110 is provided with a bent section 111, so that the lever 312 can slide into the bent section 111 to realize the positioning of the slider 311 and maintain the extended posture of the pen refill 120. The extension direction of the bent section 111 is perpendicular to the axis of the pen shell 100. When writing ends, the lever 312 slides out of the bent section 111 and slides towards the tail along the straight section of the limiting groove 110. At this time, the lever 312 drives the slider 311 away from the position held at the tail of the pen refill 120, and the spring bounces the pen refill 120 back into the pen case 100.

[0047] Thus, by providing a pen refill 120 inside the pen casing 100, and a first elastic element 130 at the end of the pen refill 120 away from the tail assembly 200, the sliding switch 310 moves in the direction away from the tail assembly 200 and pushes the pen refill 120 to squeeze the first elastic element 130, causing the pen refill 120 to extend out of the pen casing 100. When the sliding switch 310 moves in the opposite direction, it can control the on / off state of the lighting device 230 and the ejection of the pen refill 120 respectively, making operation convenient. At the same time, the positioning groove 140 can prevent the pen refill 120 from being ejected from the pen casing 100 and causing damage to the pen tip when the pen light is dropped.

[0048] The pen casing 100 is provided with a limiting groove 110, and the end of the lever 312 is provided through the limiting groove 110 so that when the lever 312 moves along the limiting groove 110, it drives the sliding member 311 to move.

[0049] It is understood that the length direction of the limiting groove 110 is set along the axis of the pen shell 100 to form an elongated limiting groove 110 on the surface of the pen shell 100, and the movement direction of the lever 312 is also along the axis of the pen shell 100. After passing through the limiting groove 110, the lever 312 is inserted into the limiting hole 313 of the slider 311. The user moves the lever 312 along the limiting groove 110, causing the lever 312 to drive the slider 311 to move within the pen shell 100, thereby controlling the lighting, which is convenient and quick to use.

[0050] Thus, by providing a limiting groove 110 in the pen housing 100, and having the end of the lever 312 pass through the limiting groove 110, the lever 312 moves along the limiting groove 110, causing the sliding member 311 to move, allowing the lever 312 to slide within the limiting groove 110, preventing the lever 312 from exceeding its preset travel distance. This would damage the lighting switch 210.

[0051] A second elastic element 150 is provided in the limiting hole 313 to eject the lever 312 from the sliding member 311 when the lever 312 is separated from the positioning groove 140. Thus, by providing the second elastic element 150 in the limiting hole 313 to eject the lever 312 from the sliding member 311 when it is separated from the positioning groove 140, the lever 312 can rise rapidly when separated from the positioning groove 140 for user control, improving the user experience.

[0052] When using the pen light, the user needs to press the lever 312, which compresses the second elastic element 150, causing the lever 312 to disengage from the positioning groove 140. Only then can the lever 312 move up and down along the axis of the pen casing 100 within the limiting groove 110, thereby driving the sliding element 311 to move up and down. When the sliding element 311 moves upward, the lighting switch 210 can be pressed; when the sliding element 311 moves downward, the pen refill 120 can be pushed to compress the first elastic element 130, causing the pen refill 120 to extend out of the pen casing 100.

[0053] Thus, by setting the lever 312 and the slider 311 to be telescopically connected with the telescopic direction perpendicular to the axis of the pen housing 100, the lever 312 retracts relative to the slider 311 when it is engaged in the positioning groove 140, and extends relative to the slider 311 when the lever 312 is separated from the positioning groove 140. This ensures that the lighting device 230 can only be switched on and off along the axis of the pen housing 100 when the lever 312 is separated from the positioning groove 140, thus preventing the lever 312 from shifting when the pen light is dropped, which could damage the internal components.

[0054] In some embodiments, the slider 311 is provided with a limiting hole 313, the axis of which is perpendicular to the axis of the slider 311, and the lever 312 passes through the limiting hole 313. The end of the lever 312 is provided with a limiting part 314, which is used to limit the lever 312 in the limiting groove 110 in a direction perpendicular to the axis of the pen shell 100.

[0055] A limiting rib 330 is provided in the limiting hole 313, and an abutment 340 is provided at the bottom of the lever 312. When the lever 312 is separated from the positioning groove 140, the abutment 340 abuts against the limiting rib 330 to prevent the lever 312 from disengaging from the sliding member 311. A limiting sleeve 350 is provided near the positioning groove 140 of the lever 312. The limiting sleeve 350 is used to engage or disengage with the positioning groove 140. A second elastic member 150 is provided between the limiting sleeve 350 and the limiting rib 330.

[0056] Thus, by providing a limiting rib 330 in the limiting hole 313 and an abutment 340 at the bottom of the lever 312, the abutment 340 abuts against the limiting rib 330 when the lever 312 separates from the positioning groove 140, preventing the lever 312 from detaching from the sliding member 311. This ensures that the lever 312 will not completely detach from the sliding member 311 when it separates from the positioning groove 140, thus preventing the loss or damage of parts. By providing a limiting sleeve 350 near the positioning groove 140 on the lever 312, the limiting sleeve 350 is used to engage or disengage with the positioning groove 140. A second elastic member 150 is provided between the limiting sleeve 350 and the limiting rib 330, so that the limiting sleeve 350 limits the lever 312 to below the positioning groove 140, further preventing the lever 312 from separating from the positioning groove 140 when the pen light is dropped.

[0057] It is understood that the lever 312 is a cylindrical lever that passes through the slider 311. The axis of the lever 312 is perpendicular to the axis of the slider 311. The slider 311 has a pair of clamping plates perpendicular to its axis, forming a limiting hole 313 between them. The clamping plates provide support for the lever 312, preventing excessive stress between the lever 312 and the slider 311 when the lever 312 moves, thus preventing the lever 312 from breaking. A limiting part 314 is located at the end of the lever 312, and the projected width of the limiting part 314 onto the limiting groove 110 is greater than the width of the limiting groove 110, preventing the lever 312 from falling out of the limiting groove 110 and thus preventing the user from controlling the lever 312. The limiting part 314 can be spherical, cylindrical, sheet-like, or plate-like; this embodiment does not impose specific limitations on the structure of the limiting part 314.

[0058] Thus, by providing a limiting hole 313 in the slider 311, with the axis of the limiting hole 313 perpendicular to the axis of the slider 311, and the lever 312 passing through the limiting hole 313, the lever 312 is prevented from separating from the slider 311 when it drives the slider 311 to move, making the movement of the slider 311 by the lever 312 more stable. By providing a limiting part 314 at the end of the lever 312, the limiting part 314 is used to limit the lever 312 in the limiting groove 110 in a direction perpendicular to the axis of the pen shell 100, preventing the lever 312 from falling into the limiting hole 313 and thus preventing the slider 311 from sliding through the lever 312, ensuring the stability of the lever 312.

[0059] In some embodiments, the end of the slider 311 facing the pen refill 120 forms a limiting cavity 316, and the end of the pen refill 120 is disposed in the limiting cavity 316.

[0060] The end of the slider 311 facing the pen refill 120 forms a limiting cavity 316 adapted to the tail of the pen refill 120, so that the tail of the pen refill 120 can be held and fixed in the limiting cavity 316, so that the slider 311 and the pen refill 120 are stably connected. Preferably, the limiting cavity 316 is provided with a spring piece 317, which clamps the tail of the pen refill 120, further improving the tightness of the connection between the slider 311 and the pen refill 120.

[0061] Thus, by forming a limiting cavity 316 at the end of the slider 311 facing the pen refill 120, and with the end of the pen refill 120 located within the limiting cavity 316, the connection between the pen refill 120 and the slider 311 becomes more stable and reliable, and the slider 311 will not deviate from the pen refill 120 when it pushes the pen refill 120 out.

[0062] When the user is using the pen lamp and needs illumination, the user slides the sliding switch 310 along the pen shell 100, causing the sliding switch 310 to move toward the tail assembly 200 at the tail of the pen lamp. A push-type lighting switch 210 is provided at the connection between the tail assembly 200 and the pen shell 100. When the sliding switch 310 touches the lighting switch 210 and is pressed, the lighting switch 210 can control the lighting device 230 to turn on and off, thus completing the illumination.

[0063] Thus, by sliding the slide switch 310 along the pen shell 100, the slide switch 310 slides to trigger the lighting switch 210 facing the slide switch 310 in the tail assembly 200, thereby controlling the lighting device 230 in the tail assembly 200 to turn on and off. The operation is simple and convenient for users to switch the lighting device 230 on and off, improving the user experience.

[0064] The lever 312 extends into the pen casing 100 and is connected to the slider 311, so that the lever 312 can protrude outside the pen casing 100, making it convenient for the user to operate while driving the slider 311 to move inside the pen casing 100.

[0065] The slider 311 is located inside the pen housing 100 and connected to the lever 312, so that the lever 312 drives the slider 311 to slide inside the pen housing 100. This allows the lever 312 to control the slider 311 to slide toward the lighting switch 210, thereby turning the lighting device 230 on and off, which is convenient to operate.

[0066] In some embodiments, the power supply 220 includes a battery and a charging device, both of which are located inside the tail assembly 200. The outer surface of the tail assembly 200 is provided with a charging interface electrically connected to the charging device. Thus, by configuring the power supply 220 to include a battery and a charging device, both located inside the tail assembly 200, and with a charging interface electrically connected to the charging device on the outer surface of the tail assembly 200, the lighting device 230 can be powered by the battery and the charging device, extending the lighting duration of the lighting device 230.

[0067] In some embodiments, the control component 300 further includes an impact plate 320, which is disposed inside the pen housing 100 and located between the slider 311 and the lighting switch 210. When the slider 311 slides toward the lighting switch 210, it pushes the impact plate 320 to move toward the lighting switch 210.

[0068] Understandably, the impact plate 320 is a circular plate adapted to the inner cavity of the pen casing 100, used to press the lighting switch 210. The impact plate 320 is located between the slider 311 and the lighting switch 210, and can move within the pen casing 100. During the movement of the lever 312 towards the lighting switch 210, the lever 312 abuts against the impact plate 320 and pushes the impact plate 320 towards the lighting switch 210. The impact plate 320, facing away from the surface of the slider 311, finally abuts against and presses the lighting switch 210, turning on the light. When the impact plate 320 is used to press the lighting switch 210, the lighting switch 210 can be conveniently positioned at any location within the plane, facilitating the utilization of space within the pen casing 100.

[0069] The sliding member 311 has a baffle 315 perpendicular to the axis of the sliding member 311 inside. The surface of the impact plate 320 facing the sliding member 311 is connected to the impact column 321. When the sliding member 311 moves toward the lighting switch 210, the baffle 315 abuts against the end of the impact column 321 to push the impact column 321 and the impact plate 320 to move.

[0070] Thus, by providing a baffle 315 perpendicular to the axis of the slider 311 inside the slider 311, and the surface of the impact plate 320 facing the slider 311 connected to the impact column 321, when the slider 311 moves toward the lighting switch 210, the baffle 315 abuts against the end of the impact column 321 to push the impact column 321 and the impact plate 320 to move. When the lever 312 drives the slider 311 to move toward the lighting switch 210, the baffle 315 in the slider 311 abuts against the impact column 321 and pushes the impact plate 320 toward the lighting switch 210, thereby increasing the contact area between the slider 311 and the impact plate 320, making the movement of the impact plate 320 more stable and reliable. The control component 300 also includes an impact plate 320, which is located inside the pen housing 100 and between the slider 311 and the lighting switch 210. When the slider 311 slides toward the lighting switch 210, it pushes the impact plate 320 toward the lighting switch 210, so that the lever 312 drives the slider 311 to slide toward the lighting switch 210 inside the pen housing 100 until the slider 311 abuts against the impact plate 320. Then, the slider 311 pushes the impact plate 320 to touch the lighting switch 210, thereby turning the lighting device 230 on and off. This ensures that the lighting switch 210 is subjected to uniform force when touched, preventing damage due to uneven force on the lighting switch 210 and extending the service life of the lighting switch 210.

Claims

1. A structurally stable pen lamp, characterized in that, The device includes a pen casing, a tail assembly, and a control assembly. The pen casing has a positioning groove. The control assembly includes a slider and a lever. The slider is located inside the pen casing, and the lever passes through the slider and the positioning groove. The lever is used to move the slider within the pen casing to activate a lighting switch in the tail assembly. The lever and the slider are telescopically connected, and the telescopic direction is perpendicular to the axis of the pen casing. This allows the lever to retract relative to the slider when engaged in the positioning groove, and to extend relative to the slider when separated from the positioning groove. The control component also includes an impact plate, which is disposed inside the pen shell and located between the slider and the lighting switch. When the slider slides toward the lighting switch, it pushes the impact plate to move toward the lighting switch. The sliding member has a baffle perpendicular to its axis. The surface of the impact plate facing the sliding member is connected to the impact column. When the sliding member moves toward the lighting switch, the baffle abuts against the end of the impact column to push the impact column and the impact plate to move. The sliding member is provided with a limiting hole, the axis of the limiting hole is set perpendicular to the axis of the sliding member, and the lever passes through the limiting hole; The limiting hole is provided with a second elastic element, which is used to eject the lever from the sliding element when the lever is separated from the positioning groove; The pen shell is provided with a limiting groove, and the positioning groove is provided in the limiting groove. The end of the lever passes through the limiting groove so that when the lever moves along the limiting groove, it drives the sliding member to move.

2. The pen lamp with stable structure as described in claim 1, characterized in that, The pen casing contains a pen refill, and the end of the pen refill away from the tail assembly is provided with a first elastic element. The slider moves in a direction away from the tail assembly and pushes the pen refill to squeeze the first elastic element so that the pen refill extends out of the pen casing.

3. A structurally stable pen lamp as described in claim 1, characterized in that, The limiting hole is provided with a limiting rib, and the bottom of the lever is provided with an abutment. When the lever is separated from the positioning groove, the abutment abuts against the limiting rib to prevent the lever from disengaging from the sliding member.

4. A structurally stable pen lamp as described in claim 3, characterized in that, A limiting sleeve is provided at the position of the lever near the positioning groove. The limiting sleeve is used to engage or disengage with the positioning groove. The second elastic element is provided between the limiting sleeve and the limiting rib.

5. A structurally stable pen lamp as described in claim 1, characterized in that, The end of the lever is provided with a limiting part, which is used to limit the lever in the limiting groove in a direction perpendicular to the axis of the pen shell.

6. A structurally stable pen lamp as described in claim 2, characterized in that, The sliding member forms a limiting cavity at the end facing the pen refill, and the end of the pen refill is located within the limiting cavity.
