Description

Technical Field

[0001] The utility model belongs to the technical field of stationery, and in particular relates to a laser ruler. Background Art

[0002] Paperweights are traditional Chinese handicrafts. They refer to tools used to press paper when writing or painting. Most commonly, they are rectangular bars, 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, the structure of a laser and a conventional ruler is used to easily realize the functions of an ordinary ruler 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 the sliding connection structure. However, the relative position of the laser line emitted by the paperweight is fixed, that is, the spacing between the lines formed by the laser line on the paper is fixed, and its applicability is not high when different font sizes are required for writing. Utility Model Content

[0004] The purpose of the utility model is to propose a laser ruler to solve the problem that the line spacing cannot be adjusted by using a laser ruler in the prior art. The device can adjust the line spacing of the laser lines on the paper according to the writing requirements, has strong applicability, and is simple and convenient to operate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A laser ruler comprises a ruler body and a laser indicator block; a movable groove is provided on the side of the ruler body; at least three groups of the laser indicator blocks are movably arranged in the movable groove; a metal conductive strip is provided on the rear side of the movable groove; a laser emitting head is provided at the front end of the laser indicator block, and a conductive connecting block is provided at the rear end; the conductive connecting block is in contact with the metal conductive strip; a control compartment is provided at the rear of the movable groove; a rechargeable battery is provided in the control compartment; the metal conductive strip is connected to the rechargeable battery; a scale is provided below the opening of the movable groove.

[0007] The ruler is in the shape of a rectangular parallelepiped and is used to be pressed on paper for writing with a brush; the laser emission head of the laser indication module can emit laser lines and irradiate them on the paper, and the intervals between multiple light rays form auxiliary grids when writing; the conductive connection block is connected to the laser emission head; the conductive metal strip draws out the current of the rechargeable battery in the control compartment and provides power to the laser emission head through the electrical connection block; when the laser indication block moves in the movable groove, the conductive connection block always contacts the metal conductive strip, so that the laser emission head is continuously powered; the scale is used to mark the interval of the laser indication block, so that the user can adjust the position of the laser indication block to form a laser grid with a desired interval width on the paper; the laser emitted by the laser emission is tilted downward, so that the laser forms lines on the paper.

[0008] As a further technical improvement, two sets of guide rails are respectively provided on the upper side and the lower side of the movable groove.

[0009] As a further technical improvement, two sets of guide grooves are respectively provided on the upper and lower surfaces of the laser indicator block; the guide grooves are correspondingly matched and movably engaged with the guide rails. The laser indicator block moves on the guide rails through the guide grooves, thereby adjusting the relative position of the laser indicator block and finally adjusting the width of the laser grid on the paper.

[0010] As a further technical improvement, the front end of the laser indicator block is provided with an indicator line groove; the indicator line groove is directly opposite to the scale line on the scale. The indicator line groove corresponds to the position of the laser line emitted by the laser indicator block; the position of the laser line on the paper can be accurately adjusted by aligning the indicator line groove with the corresponding scale line on the scale, thereby adjusting the laser line width.

[0011] As a further technical improvement, a hollow groove is provided at the rear of the scale. The side of the hollow groove is used to draw the scale lines of the scale; the hollow groove is hollowed out to reduce weight.

[0012] As a further technical improvement, the side of the control compartment is closed; a switch and a charging interface are provided on the side of the control compartment. A control component is also provided in the control compartment, which is used to connect the switch with the conductive metal strip, and control the start and stop of the laser transmitter by controlling the on and off of the current on the conductive metal strip; and the control component also connects the charging interface with the rechargeable battery, so that the charging interface can charge the rechargeable battery after connecting the charger.

[0013] As a further technical improvement, the two sides of the movable groove are open, so that the laser indicator block can be inserted into the movable groove from the side. In this way, more laser indicator blocks can be added, so as to adjust and irradiate more laser lines on the paper.

[0014] The above-mentioned method of using a laser ruler:

[0015] When in use, first insert the corresponding number of laser indicator blocks into the movable slot; then, according to the writing needs, push the laser indicator block to adjust the distance between adjacent laser indicator blocks, and obtain the distance value between the laser indicator blocks from the scale; at this time, the conductive connecting block is always in contact with the metal conductive strip; turn on the device, the laser emitter emits laser, and hits the writing paper, so that rows formed by laser light appear on the paper, and the row grid spacing is the distance between the laser emission positions of two adjacent groups of laser indicator blocks on the scale.

[0016] The technical solution of the utility model has the following beneficial effects:

[0017] 1. The utility model device adopts the form of detachable and movable sleeve laser indicator blocks in the movable groove, so that the user can increase, decrease and adjust the number and spacing of laser indicator blocks according to writing needs, thereby adjusting the number and spacing of laser light lines appearing on the paper, so that the device can be suitable for different writing needs and has a wide range of applicability.

[0018] 2. The utility model emits laser light through the laser emitting head on the laser indicating block, which can form lines composed of laser light on the paper, thus playing a role in assisting the user in writing.

[0019] 3. The utility model enables the user to accurately adjust the position of the laser indicator block through the scale and the indicator line groove, so that the spacing between the laser light lines on the paper can be adjusted, so that the spacing between each line is the same, which is helpful for the user to write.

[0020] 4. The utility model uses the metal conductive strip and the conductive connecting block to enable the laser indicator block to conduct electricity when moving, thereby ensuring that the laser indicator block can continuously emit laser. BRIEF DESCRIPTION OF THE DRAWINGS
