Description

Technical Field

[0001] The utility model relates to the technical field of laser pens, in particular to a laser pen capable of preventing rolling and loss. Background Art

[0002] Laser pens are commonly used in lectures, speeches, meetings, business presentations, and other settings to indicate specific locations and key points during presentations. Currently, most laser pens are cylindrical in shape, and due to their smooth, rounded exterior, they are prone to rolling and being lost. Especially when designed with a detachable pen body and cap, the cap is smaller, making it more prone to rolling and sometimes difficult to find, increasing the probability of loss. To avoid this, existing split-body laser pens often use a cord to connect the components to prevent loss, but this is often inconvenient. Some laser pens are designed to be stored in a fixed holder on a lectern or conference table, but when used portable, this prevents the pen from being lost. Furthermore, high-end laser pens are typically made of anodized metal, which is expensive to manufacture and difficult to produce in multiple colors. Most are black, resulting in a single color palette for laser pens. Utility Model Content

[0025] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0026] like Figures 1 to 4 As shown, the anti-rolling laser pen has a large contact surface with a support, such as a tabletop, when placed, preventing rolling and thus significantly reducing the chance of rolling or being lost. This embodiment includes a laser pen body 1, which is configured to be flat, thereby forming surface contact with the support to ensure stability and firmness when placed. Specifically, the end face of the laser pen body 1 is provided with two opposing and parallel straight edges and two opposing curved edges, and each curved edge is smoothly connected to the other straight edges. In other words, the end face of the laser pen body 1 has an overall runway-shaped structure, with the surface of the straight edges forming a flat surface to ensure contact with the support when placed.

[0027] An adsorbent cap 2 is partially mounted on the outer periphery of the laser pen body 1. The shape of the cap 2 matches that of the laser pen body 1, namely, the cap 2 is a hollow cylindrical structure with a runway-shaped end surface. It is directly and detachably mounted on the laser pen body 1. The adsorbent cap 2 has an adsorbent property, which can enhance the fixation of the laser pen body 1 when in contact with the support, thereby preventing it from being dropped or lost.

[0028] The absorbent pen cap 2 of this embodiment includes a soft rubber outer shell 21, which encapsulates a magnetic inner core 22. The magnetic inner core 22 is magnetic and can be adsorbed to the surface of a metal support, such as a magnetic conference board in a conference room, a metal base of a computer, or a metal housing of a monitor, thereby achieving adsorption and fixation, and also preventing the pen from rolling away and being lost. The soft rubber outer shell 21 can be made of rubber, which is relatively soft in texture. It can also provide a certain buffering and protective effect when the laser pen body 1 falls due to a user's loose grip.

[0029] Specifically, if Figure 4 As shown, the magnetic core 22 is configured as an integrated soft magnetic sheet wrapped in the soft rubber outer shell 21, which is convenient for processing and manufacturing. Figure 5 As shown, the magnetic inner core 22 can also be set as a plurality of soft magnetic strips, each of which is parallel and evenly distributed in the soft rubber outer shell 21, which can reduce the amount of soft magnetic material used and reduce the cost of manufacturing materials.

[0030] In this embodiment, at least the outer surface of the soft rubber outer shell 21 is uniformly and uniformly provided with parallel anti-slip ridges 23. These ridges 23 are arranged along the axial direction of the soft rubber outer shell 21. During use, these ridges provide high friction with the hand, ensuring a secure grip. When these ridges 23 are provided, the soft magnetic strip can be placed between two adjacent ridges 23.

[0031] To enhance the aesthetics of the laser pen body 1, a decorative color layer 24 can be provided on at least the outer surface of the soft rubber outer shell 21, such as red, white, gray, yellow, etc., to provide a certain degree of decorative beauty to the laser pen body 1, diversify its colors, and thus increase customer choice. In the actual production process, the decorative color layer 24 can be provided separately on the surface of the soft rubber outer shell 21, or the pigment can be incorporated into the material used to make the soft rubber outer shell 21 and integrally formed with the soft rubber outer shell 21, which can also serve to beautify the laser pen product.

[0032] The laser pen body 1 of this embodiment comprises a snap-fit ​​pen body 11 and a pen cap 12. The pen cap 12 protects the laser emitter when not in use. The end surface of the pen cap 12 is also shaped like a racetrack to fit the pen body 11. This prevents the pen cap 12 from rolling away and getting lost when placed on a table after removal. The pen body 11 is equipped with an operation button 13, an indicator light 14, and a charging port 15. These buttons 13, indicator light 14, and charging port 15 are all exposed on the outside of the absorbent pen cap 2. The operation button 13 facilitates control of the laser pen, while the indicator light 14 indicates the power level of the laser pen, allowing for timely recharging to prevent interruptions to normal use due to low power. The charging port 15 is a USB port that works with a data cable and charger to recharge the laser pen. The internal structure and operating principle of the laser pen body 1 are well known to those skilled in the art and will not be described in detail here.

[0033] The description of the present invention is provided for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
