Description

Technical Field

[0001] The utility model relates to the technical field of stationery, in particular to an electrically driven laser ruler. Background Art

[0002] Paperweights are traditional Chinese handicrafts. They refer to things used to press paper when writing or painting. Most commonly, they are rectangular strips, so they are also called rulers or pressure rulers. Calligraphers and calligraphy enthusiasts often encounter a problem. In the process of writing calligraphy with a brush, in order to meet the needs of the integrity of the writing layout and the layout specifications of the chapters, it is often necessary to fold the rice paper into fold lines or grid lines as auxiliary lines for writing, or measure the size with a ruler and draw auxiliary lines with a pencil for positioning. At present, this work can be completed with the assistance of a paperweight. In the relevant technology, a laser and a conventional ruler weight structure are used to easily realize the functions of an ordinary ruler weight and auxiliary lines.

[0003] For example, Chinese patent CN 213565203 U discloses a paperweight, including a paperweight body, a light emitter, a circuit board and a switch, wherein the paperweight body is provided with a mounting groove, and a plurality of light emitters are fixedly arranged in the mounting groove and can emit light outwardly toward the same side of the paperweight body, thereby forming a light beam used as an auxiliary line. A plurality of switches are connected to each light emitter in a one-to-one correspondence, and are used to switch the corresponding light emitter on and off. The interval change of the light beam is achieved by adjusting the light emitter emitting light. Only the switch needs to be switched on and off, and the light emitter does not need to be moved, so that the adjustment is convenient, and the connection structure is simpler than that of the sliding connection structure. However, the relative position of the laser line emitted by the paperweight is a fixed interval, and its applicability is not high when different font sizes are required for writing.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings.

[0035] like Figures 1 to 9 As shown, the utility model provides an electrically driven laser ruler, comprising a lower shell 1, an upper shell 2, an inner support body 3 and a driving assembly 4, wherein the lower shell 1 and the upper shell 2 are both in a rectangular shape, and the upper shell 2 is connected to the upper end of the lower shell 1, that is, the upper shell 2 and the lower shell 1 constitute the outer shell of the electrically driven laser ruler; after the lower shell 1 and the upper shell 2 are connected, a shell structure with an internal cavity is formed for installing the electronic equipment and internal components of the electrically driven laser ruler, that is, the inner support body 3 and the driving assembly 4 are connected to the cavity inside the lower shell 1 and the upper shell 2, and the driving assembly 4 is connected to the upper end of the inner support. The driving assembly 4 includes a scissors-type telescopic mechanism 41, a laser pointing assembly 42 and an electric push rod 43, wherein the scissors-type telescopic mechanism 41 is used to drive the movement of the laser pointing assembly 42, and the laser pointing assembly 42 is used to realize the effect of laser emission and thus lighting on paper. Specifically, the laser pointing assembly 42 can produce a strip-shaped laser line; one end of the scissors-type telescopic mechanism 41 is connected to the end of the inner bracket body 3, and the laser pointing assembly 42 includes a plurality of laser pointing assemblies 42 that are respectively connected to the upper end of the scissors-type telescopic mechanism 41 at intervals, and both ends of the electric push rod 43 are respectively connected between the scissors-type telescopic mechanism 41 and the inner bracket body 3 to drive the scissors-type telescopic mechanism 41 to realize the telescopic action.

[0036] When the electric-driven laser ruler of the utility model is used, one or more electric-driven laser rulers are first placed on the paper according to the requirements of calligraphy and painting. Since the gravity of the electric-driven laser ruler of the utility model can be pressed well on the paper of calligraphy and painting, the laser indication component 42 is turned on at this time so that the device can produce multiple parallel strip laser lines. The spacing between the laser indication components 42 is adjusted according to the requirements of writing, that is, the scissor-type telescopic mechanism 41 is driven to contract or open by the electric push rod 43, thereby driving the movement of the laser indication component 42. Since the spacing between each section on the scissor-type telescopic mechanism 41 is equal, the spacing between each laser indication component 42 is also kept in the same state, so that the multiple laser lines produced by the electric-driven laser ruler are parallel to each other and the distance between them is equal. The utility model discloses an electric-driven laser ruler weight, which is internally provided with an electric push rod 43 cooperating with a laser indicating assembly 42, and can conveniently and quickly adjust the distance between various laser lines, thereby facilitating timely adjustment of the spacing between the laser lines according to different needs, thereby better improving the applicability of the electric-driven laser ruler weight, that is, the distance between the laser lines can be conveniently and quickly adjusted according to different writing requirements, and has a good paperweight effect.

[0037] like Figures 4 to 9 As shown, further, the utility model is an electric-driven laser ruler. In order to reduce the volume occupied by the driving mechanism of the electric-driven laser ruler, the electric push rod 43 includes a push rod bracket and a telescopic rod. The end of the telescopic rod away from the push rod bracket is connected to the scissor-type telescopic mechanism 41, and the end of the push rod bracket away from the telescopic rod is connected to the inner support body 3. When the telescopic rod moves into the push rod bracket, it pulls the scissor-type telescopic mechanism 41 to expand. Specifically, the inner support body 3 includes a fixed support column 34 and an inner support column 33. The fixed support column 34 is arranged at the end of the inner support body 3, and one end of the scissor-type telescopic mechanism 41 is rotatably connected to the fixed support column 34; the inner support column 33 is close to the middle position of the inner support, and the end of the push rod bracket away from the telescopic rod is fixedly connected to the inner support column 33. That is, since the scissors-type telescopic mechanism 41 has a large telescopic ratio, that is, its size after contraction is relatively large compared to its size after extension, in order to effectively utilize its extension and contraction characteristics, the electric push rod 43 is pulled in a pulling form, and the internal dimensions of the entire electric-driven laser ruler are better utilized.

[0038] like Figures 2 to 11As shown, further, the utility model is an electrically driven laser ruler. To ensure the flexibility and reliability of the laser indication component 42, the upper ends of both sides of the inner support body 3 are respectively connected with the first guide rail 31 and the second guide rail 32. The laser indication component 42 includes a support plate 421 in a long plate-like structure. The lower sides of both ends of the support plate 421 are respectively fixedly connected with the first slider 422 and the second slider 423. The first slider 422 is slidably connected to the first guide rail 31, and the second slider 423 is slidably connected to the second guide rail 32. That is, the first guide rail 31 and the second guide rail 32 are designed on both sides of the long side of the inner support body 3 to cooperate with the first slider 422 and the second slider 423 at both ends of the support plate 421. Combined with the scissor-type telescopic mechanism 41, the support plate 421 can slide smoothly, thereby ensuring that the laser lines emitted by the laser emitting component better maintain the same spacing with each other. In order to better ensure the flexibility and reliability of the laser pointing assembly 42, the laser pointing assembly 42 also includes a connecting column 424 and a laser 425. The laser 425 is connected to the upper side of one end of the support plate 421. The connecting column 424 is a cylindrical structure fixedly connected to the middle position of the support plate 421, and the scissor telescopic mechanism 41 is rotatably connected to the connecting column 424. That is, the laser 425 is fixedly connected to the support plate 421, and the support plate 421 is provided with a connecting column 424 connected to the scissor telescopic mechanism 41, so that the scissor telescopic mechanism 41 can more reliably drive the laser pointing assembly 42 to move. Furthermore, in order to improve the aesthetics of the outside of the ruler, a long strip-shaped light outlet slot 22 is opened on the side of the upper shell 2, and a transparent baffle is connected to the light outlet slot 22, and the laser emitted by the laser 425 can pass through the transparent baffle. That is, a long strip opening is provided at the position where the laser 425 emits laser light, so that a plurality of lasers 425 can be connected to emit laser light, thereby improving the applicability of the electrically driven laser ruler.

[0039] like Figures 1 to 3As shown, further, the utility model is an electrically driven laser ruler. In order to facilitate the identification of the intervals between the laser lines emitted by the laser indication component 42, so as to better improve the precise intervals between the laser lines, the side of the lower shell 1 is provided with a scale 11, and the scale 11 is arranged along the moving direction of the laser indication component 42. That is, through the scale 11 arranged on the side of the lower shell 1, the distance between the laser lines emitted by the laser indication component 42 can be more intuitively understood, so that timely adjustments can be made according to actual needs, which is more conducive to calligraphy creation. Further, in order to improve the stability of the electrically driven laser ruler during use, the lower shell 1 is provided with an anti-skid groove 12, and the anti-skid groove 12 includes a plurality of anti-skid grooves 12 and is staggered at the bottom of the lower shell 1. Since the electrically driven laser ruler is combined with the function of an ordinary ruler, in order to make it have a better ruler-stabilizing effect, an anti-skid groove 12 with an anti-skid effect is provided at the bottom of the lower shell 1, and the anti-skid grooves 12 are staggered to better ensure the anti-skid effect of the anti-skid grooves 12. As shown Figures 1 to 3 As shown, further, in order to facilitate the placement of the electric-driven laser ruler and thus improve the use efficiency of the electric-driven laser ruler, the two ends of the outer side of the upper shell 2 are provided with card holder slots 21, and the card holder slots 21 are concave structures relative to the surface of the upper shell 2. That is, by providing the card holder slots 21 on both sides of the upper shell 2, when moving the electric-driven laser ruler, it is possible to hold the card holder slots 21 by hand to move it conveniently.

[0040] Furthermore, in the utility model, an electric-driven laser ruler is used. In order to improve the comfort of using the electric-driven laser ruler and ensure the reliability of the electric-driven laser ruler when in use, the upper shell 2 is made of non-metallic materials, and the lower shell 1 is made of metal materials. That is, the lower shell 1 is made of metal materials such as stainless steel or copper, aluminum and other commonly used metal materials with good corrosion resistance to ensure the overall weight and structural strength of the electric-driven laser ruler. The weight of the electric-driven laser ruler can be appropriately increased to ensure its use effect when it is used as a conventional ruler. In order to improve the appearance of the electric-driven laser ruler, non-metallic materials such as high-grade wood or other materials with good colors are used, which can better improve the beauty of the electric-driven laser ruler, which is conducive to giving the author a better aesthetic feeling during the calligraphy and painting process, thereby improving the good mood during the calligraphy and painting process.
