Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of size measuring equipment, in particular to a digital caliper for measuring granite. Background Art
[0002] When granite is processed into slabs, blocks or specific shapes, precise measurements are required to ensure that the processed dimensions meet the design requirements, so digital vernier calipers are often used.
[0003] When measuring and drawing on hard and smooth granite, the current digital vernier caliper may slip due to accidental touching of the digital vernier caliper, thereby losing the original measurement origin and making it impossible to continue the measurement on the original basis. Utility Model Content
[0004] The utility model aims to provide a digital caliper for measuring granite, which can be used as a caliper and also as a circle drawing tool.
[0005] The granite measuring digital caliper comprises a main scale arranged horizontally, a vernier which can move left and right along the main scale is installed on the main scale, a digital display module which moves with the vernier is fixed on the vernier, the right end of the main scale is the measuring starting point, a longitudinal sleeve is fixed on the front side of the main scale at the measuring starting point, the rear end of the sleeve is connected to the main scale, a connecting tube which can only rotate left and right is longitudinally connected to the sleeve, the rear end of the connecting tube is connected to the sleeve in a rotating matching manner, a suction cup which is adsorbed forward is connected to the front end of the connecting tube, and the vertical center line of the suction cup coincides with the measuring starting point;
[0006] A fixing groove for fixing the painting pen is provided at the right end of the digital display module. The fixing groove is arranged to be connected front to back and is an arc-shaped structure. The center line of the arc coincides with the center line of the suction cup. A detachable fixing sheet is installed on the digital display module at the fixing groove.
[0007] A protective pad is installed on the front side wall of the digital display module.
[0008] The digital display module is used to display the data measured by the vernier. The protective pad can protect the caliper when it is used and placed to reduce wear. When measuring granite, the suction cup can locate the starting point of the measurement. When leaving midway or needing to locate, it can avoid the situation where the starting point of the measurement cannot be found due to no marking or too many markings. The brush is fixed in the fixed groove by a fixing piece. The center line of the brush coincides with the center line of the suction cup. After the brush moves to the left with the cursor, the connecting tube can only rotate left and right along the sleeve. The data displayed by the digital display module can be used as the radius, and the main ruler can be rotated to draw a circle with the suction cup as the center. It can be used as a caliper and a circle drawing tool. When the cursor is at the starting point of the measurement, due to the obstruction of the main ruler, the brush can only be extended and fixed in the fixed groove after the cursor moves to the left, and then a circle can be drawn.
[0009] Furthermore, a circular groove is processed at the front end of the connecting tube, an internal thread is processed on the inner wall of the circular groove, and an external thread that is threadably matched with the internal thread of the circular groove is processed at the rear end of the suction cup.
[0010] The suction cup and the connecting tube are connected by threads, which is convenient for installation and disassembly.
[0011] Furthermore, a through hole communicating front to back is provided on the connecting tube at the rear end of the circular groove, and the front end of the sleeve independently extends into the through hole and is connected to the connecting tube in a rotationally matched manner.
[0012] The through hole facilitates the rotational connection between the connecting tube and the sleeve.
[0013] Furthermore, the diameter of the circular groove is larger than the aperture of the through hole, the inner wall of the sleeve is processed with an internal thread, and the front end of the sleeve independently passes through the through hole and limits the connecting tube by bolts.
[0014] The front end of the sleeve extends into the circular groove, and then the screw rod of the bolt is threadedly matched with the internal thread of the sleeve to limit the connecting tube and prevent the connecting tube from slipping out of the front end of the sleeve. In actual use, the prior art can also be used to set a bearing on the sleeve, the inner ring of the bearing is fixed on the sleeve, and the outer ring of the bearing is installed in the through hole, so that the connecting tube can only rotate left and right relative to the sleeve. Other rotationally matched connection methods in the prior art can also be used.
[0015] Furthermore, installation grooves are provided at the upper and lower ends of the left side wall of the digital display module, the upper and lower ends of the protective pad are bent, and can extend into the installation groove from the left end of the digital display module, and the protective pad is connected to the installation groove in an interference fit.
[0016] In actual use, the protective pad can also be inserted into the installation groove and then limited by fasteners such as bolts to facilitate disassembly, assembly and replacement.
[0017] Furthermore, threaded holes for locking the fixing plate are processed on the digital display modules at the upper and lower ends of the fixing groove.
[0018] The threaded holes are convenient for adjusting the tightness of the upper and lower ends of the fixing plate by means of bolts.
[0019] Furthermore, the fixing plate is in an arc-shaped structure with its opening facing leftwards.
[0020] The arc-shaped structure of the fixing plate and the arc-shaped structure of the fixing groove hold and fix the paintbrush together, making it more stable and not easy to shift.
[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] When measuring granite, the suction cup can locate the measurement starting point. When leaving halfway or needing to locate, it can avoid the situation where the measurement starting point cannot be found due to no marking or too many markings. The brush is fixed in the fixed groove by a fixing plate, and the center line of the brush coincides with the center line of the suction cup. After the brush moves to the left with the cursor, the connecting tube can rotate left and right on the sleeve. The data displayed on the digital display module can be used as the radius, and the main ruler can be rotated to draw a circle with the suction cup as the center. It can be used as a caliper and as a circle drawing tool. BRIEF DESCRIPTION OF THE DRAWINGS
