Abstract
Description
Technical Field
[0001] This utility model relates to the field of levelness measurement technology, and in particular to a levelness measurement device for graphic design. Background Technology
[0002] In the fields of architecture, engineering, and graphic design, slope measuring instruments are a commonly used tool for detecting the levelness and tilt angle of an object's surface.
[0003] However, traditional multi-functional slope measuring instruments typically employ an integrated structure. The parts of the instrument that directly contact the object being measured, such as the bottom and sides, are subject to continuous friction and impact during long-term use. This wear is particularly pronounced when repeatedly measuring on rough or uneven surfaces, significantly accelerating the wear rate of these contact points. This wear not only leads to blurred scales and difficulty in reading, but also directly affects measurement accuracy due to decreased surface flatness. It can even introduce systematic errors due to localized deformation. Because these critical contact parts are fixedly connected to the instrument body or manufactured as a single unit, users cannot replace worn components individually. If the measuring strip is damaged or malfunctions, the only option is to repair the entire measuring instrument or purchase new equipment, increasing operating costs. Therefore, this paper proposes a planar design levelness measuring device to overcome these shortcomings. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a levelness measuring device for planar design.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a levelness measuring device for planar design, comprising a measuring instrument body, a horizontal rail fixedly connected to the bottom of the measuring instrument body, a top block fixedly connected to the top left side of the horizontal rail, a vertical rail fixedly connected to the top of the top block, a horizontal bar slidably connected to the inner side of the horizontal rail, a vertical bar slidably connected to the inner side of the vertical rail, a corner block slidably connected to the inner side of the top block, a first fixed shaft rotatably connected to the lower right end face of the measuring instrument body, a first clamping plate fixedly connected to the outer side of the first fixed shaft, a second fixed shaft rotatably connected to the top left side of the measuring instrument body, a second clamping plate fixedly connected to the outer side of the second fixed shaft, magnetic sheets fixedly connected to the top outer side of the first and second clamping plates near the measuring instrument body, bolts spirally connected to the middle left side of the first clamping plate and the middle lower side of the second clamping plate, the right end face of the horizontal bar and the top of the vertical bar being made of magnetically attractable metal, and both the right end face of the horizontal bar and the top of the vertical bar being magnetically attracted and fixed by magnetic sheets.
[0006] As a further description of the above technical solution: The left end face of the measuring instrument body is fixedly connected to the right end face of the vertical rail. The top of the lower left corner of the measuring instrument body is fixedly connected to the top of the upper right corner of the top block. The bottom of the measuring instrument body is slidably connected to the top of the horizontal bar. The left end face of the measuring instrument body is slidably connected to the right end face of the vertical bar. The top of the right side of the horizontal rail contacts the left end face of the first clamping plate. Both the middle of the top of the right side of the horizontal rail and the middle of the top of the vertical bar are screwed with bolts, which can quickly replace the horizontal bar and the vertical bar that have been in contact with the measured object for a long time and thus cause wear or damage, avoiding the situation that the measurement result of the measuring instrument body deviates due to the wear of the horizontal bar or the vertical bar.
[0007] As a further description of the above technical solution: The longitudinal section shape of the horizontal rail is the same as the transverse section shape of the vertical rail. The length of the horizontal rail matches the length of the bottom of the measuring instrument body, and the length of the vertical rail matches the longitudinal length of the left end face of the measuring instrument body. The horizontal bar and the vertical bar are replaced by an insertion and sliding method. With the fixation of the first clamping plate, the second clamping plate and the bolt, it can be avoided that when the horizontal bar and the vertical bar contact the detected object and slide, the horizontal bar and the vertical bar are separated from the inner sides of the horizontal rail and the vertical rail due to the friction of the detected object.
[0008] As a further description of the above technical solution: Both the horizontal bar and the vertical bar are composed of a clamping bar and a contact plate. The clamping bar slides in the horizontal rail and the vertical rail. The inner sides of the horizontal rail and the vertical rail are provided with sliding grooves, and the section shape of the sliding groove matches the longitudinal section shape of the clamping bar. The longitudinal section shape of the horizontal bar and the transverse section shape of the vertical bar are both "soil" shaped. The horizontal bar and the vertical bar can only slide in the horizontal rail and the vertical rail, and cannot be forcibly separated from the horizontal rail and the vertical rail by pulling.
[0009] As a further description of the above technical solution: The number of the top blocks is two groups, and the top blocks are distributed at the front and rear tops of the lower left corner of the measuring instrument body. The distance between the top blocks is the same as the width of the inner center of the angle block, and the front and rear length of the angle block is the same as the total front and rear length between the two top blocks at the top of the lower left corner of the measuring instrument body. The setting of the angle block enables the measuring instrument body to have the ability to measure a 90° angle while the horizontal bar and the vertical bar can be replaced, and the angle block has a detachable effect, and has the same detachable and replaceable effect as the horizontal bar and the vertical bar.
[0010] As a further description of the above technical solution: a reserved hole is provided in the middle of the lower part of the first card plate and in the middle of the left side of the second card plate. A reserved groove is provided on the right end face of the horizontal bar and the top of the vertical bar. The cross-sectional diameter of the reserved hole and the reserved groove are matched with the cross-sectional diameter of the bolt. This allows the first card plate to restrict the top right side of the horizontal bar and the second card plate to restrict the top of the vertical bar. Both the first card plate and the second card plate are fixed to the horizontal bar and the vertical bar by bolts, which improves the stability and ease of replacement of the horizontal bar and the vertical bar to a certain extent.
[0011] This utility model has the following beneficial effects:
[0012] The planar design levelness measuring device of this utility model, through the design and cooperation of the horizontal and vertical rails, allows for the quick replacement of the horizontal and vertical rails that have been in contact with the object being measured for a long time, resulting in wear or damage. The replacement method adopts an insertion and sliding mechanism, which, together with the first and second clamping plates and bolts for fixing, can prevent the horizontal and vertical rails from detaching from the inner side of the horizontal and vertical rails due to friction from the object being measured when they are in contact with and sliding. This improves the stability and ease of replacement of the horizontal and vertical rails to a certain extent. Attached Figure Description

[0019] Reference Figures 1 to 4, a level measurement device for graphic design provided by the utility model includes a measuring instrument body 1. A horizontal rail 2 is provided at the bottom of the measuring instrument body 1. A top block 3 is welded to the top left end of the horizontal rail 2. A vertical rail 4 is welded to the top of the top block 3. A horizontal bar 5 is inserted and slides inside the horizontal rail 2. A vertical bar 6 is inserted and slides inside the vertical rail 4. A corner block 7 is inserted inside the top block 3. A first fixed shaft 8 is provided below the right end face of the measuring instrument body 1. A first clamping plate 9 is welded to the outside of the first fixed shaft 8. A second fixed shaft 10 is provided on the left side of the top of the measuring instrument body 1. A second clamping plate 11 is welded to the outside of the second fixed shaft 10. Magnetic pieces 13 are provided at the outer top ends of the end faces of the first clamping plate 9 and the second clamping plate 11 close to the measuring instrument body 1. Bolts 12 are inserted and screwed in the middle of the left side inside the first clamping plate 9 and the middle of the lower part inside the second clamping plate 11;
[0020] The left end face of the measuring instrument body 1 is fixedly connected to the right end face of the vertical rail 4. The top left corner of the measuring instrument body 1 is fixedly connected to the top right corner of the top block 3. The bottom of the measuring instrument body 1 is slidably connected to the top of the horizontal bar 5. The left end face of the measuring instrument body 1 is slidably connected to the right end face of the vertical bar 6. The top right end of the horizontal rail 2 contacts the left end face of the first clamping plate 9. The middle of the top right end of the horizontal rail 2 and the middle of the top of the vertical bar 6 are both screwed with bolts 12. The horizontal bar 5 and the vertical bar 6 that have been in contact with the measured object for a long time during measurement and have thus caused wear or damage can be quickly replaced, avoiding the situation where the measurement result of the measuring instrument body 1 is deviated due to the wear of the horizontal bar 5 or the vertical bar 6.
[0021] As a further implementation of the above technical solution: The longitudinal section shape of the horizontal rail 2 is the same as the transverse section shape of the vertical rail 4. The length of the horizontal rail 2 matches the length of the bottom of the measuring instrument body 1, and the length of the vertical rail 4 matches the longitudinal length of the left end face of the measuring instrument body 1. The horizontal bar 5 and the vertical bar 6 are replaced by an insertion and sliding method. With the fixation of the first clamping plate 9, the second clamping plate 11 and the bolts 12, the problem that the horizontal bar 5 and the vertical bar 6 are separated from the inside of the horizontal rail 2 and the vertical rail 4 due to the friction of the measured object when the horizontal bar 5 and the vertical bar 6 contact the measured object and slide can be avoided.
[0022] As a further implementation of the above technical solution: Both the horizontal bar 5 and the vertical bar 6 are composed of a clamping bar and a contact plate. The clamping bar slides inside the horizontal rail 2 and the vertical rail 4. Chute grooves are provided inside the horizontal rail 2 and the vertical rail 4, and the cross-section shape of the chute grooves matches the longitudinal section shape of the clamping bar. The longitudinal section shape of the horizontal bar 5 and the transverse section shape of the vertical bar 6 are both in the shape of "soil". The horizontal bar 5 and the vertical bar 6 can only slide inside the horizontal rail 2 and the vertical rail 4, and cannot be forcibly separated from the horizontal rail 2 and the vertical rail 4 by pulling.
[0023] As a further implementation of the above technical solution: there are two sets of top blocks 3, and the top blocks 3 are distributed on the front and rear tops of the lower left corner of the measuring instrument body 1. The distance between the top blocks 3 is the same as the width of the inner center of the corner block 7, and the front and rear length of the corner block 7 is the same as the total front and rear length between the two top blocks 3 at the lower left corner of the measuring instrument body 1. The setting of the corner block 7 allows the measuring instrument body 1 to measure a 90° angle while replacing the horizontal bar 5 and the vertical bar 6. The corner block 7 is detachable, and has the same detachable and replaceable effect as the horizontal bar 5 and the vertical bar 6.
[0024] As a further implementation of the above technical solution: a reserved hole is provided in the middle of the lower part of the first card plate 9 and in the middle of the left side of the second card plate 11. A reserved groove is provided on the right end face of the horizontal strip 5 and the top of the vertical strip 6. The cross-sectional diameter of the reserved hole and the reserved groove are matched with the cross-sectional diameter of the bolt 12. This allows the first card plate 9 to restrict the top right side of the horizontal strip 5 and the second card plate 11 to restrict the top of the vertical strip 6. The first card plate 9 and the second card plate 11 are both fixed to the horizontal strip 5 and the vertical strip 6 by bolts 12, which improves the stability and ease of replacement of the horizontal strip 5 and the vertical strip 6 to a certain extent.
[0025] As a further implementation of the above technical solution: the right end face of the horizontal strip 5 and the top of the vertical strip 6 are made of magnetically attracted metal, and the right end face of the horizontal strip 5 and the top of the vertical strip 6 are both magnetically attracted and fixed by the magnetic sheet 13. The magnetic attraction of the magnetic sheet 13 can give the first card plate 9 a certain degree of positioning effect on fixing the horizontal strip 5 and the second card plate 11 on the vertical strip 6.
[0026] Working principle:
[0027] When using this utility model, insert the horizontal bar 5 into the inner side of the horizontal rail 2 at the bottom of the measuring instrument body 1 from left to right, and insert the vertical bar 6 into the inner side of the vertical rail 4 on the left end face of the measuring instrument body 1 from top to bottom. First, the end of the horizontal bar 5 with the reserved groove is set on the right side. Insert the top left side of the horizontal bar 5 into the inner side of the right end face of the horizontal rail 2 until the top left side of the horizontal bar 5 contacts the right end face of the top block 3. Move the first clamping plate 9 downward. The first clamping plate 9 rotates downward around the first fixed shaft 8 as the base point until the magnetic piece 13 on the lower left end face of the first clamping plate 9 is magnetically attracted and fixed to the right end face of the horizontal bar 5. Then, remove the bolt 12 and insert it into the reserved hole inside the first clamping plate 9 and the right end of the horizontal bar 5. Tighten the screw in the reserved groove on the surface, then tighten the vertical bar 6. The end of the vertical bar 6 with the reserved groove is set at the top. Insert the bottom of the vertical bar 6 into the top inner side of the vertical rail 4 from top to bottom until the bottom of the vertical bar 6 contacts the top of the top block 3. Rotate the second clamping plate 11. The second clamping plate 11 rotates to the left with the second fixed shaft 10 as the base point until the magnetic piece 13 on the left side of the lower end face of the second clamping plate 11 is magnetically fixed to the top of the vertical bar 6. Then use the bolt 12 to insert and tighten it in the reserved hole inside the second clamping plate 11 and the reserved groove on the top of the vertical bar 6. Finally, insert the corner block 7 between the top blocks 3. The operator holds the measuring instrument body 1 and begins the measurement operation.
