Description

Technical Field

[0001] The utility model relates to the field of measurement technology related to architectural design, and specifically relates to a measuring ruler for architectural design. Background Art

[0002] Architectural design is done before a building is constructed. In order to facilitate the staff to have a grasp of the various dimensions of the building materials, it is necessary to use a corresponding measuring ruler to perform measurement work. As we all know, when observing the scale of the measuring ruler, the eyes need to be directly above the scale line to ensure that there is no deviation. For high-altitude measurements, in order to ensure that the eyes are looking directly at the scale line, two people are required to operate, one holding the ruler below and the other observing from above, which is prone to errors. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a measuring ruler for architectural design.

[0004] The technical solution adopted by this utility model:

[0005] A measuring ruler for architectural design comprises an outer tube and an inner tube. The outer tube is sleeved onto the inner tube, with a clearance fit between the outer and inner tubes. A nut is provided at the inner end of the inner tube wall, forming an integral structure with the inner tube. The nut is threadedly sleeved onto a lead screw, the lower portion of which is fixedly connected to a stepped shaft A. A permanent magnet is fixedly connected to the outer wall of the stepped shaft A. An induction coil is embedded around the inner wall of the outer tube, the permanent magnet corresponding to the induction coil, and the induction coil and the permanent magnet are in sliding engagement. A handle is fixedly connected to the lower portion of the outer tube, which is provided with a display screen. A counting chip is integrated into the display screen, and a wire connects the counting chip to the induction coil.

[0006] The lower part of the step shaft A is fixedly connected to the step shaft B. The diameter of the step shaft B is smaller than that of the step shaft A. The outer wall of the step shaft B is sleeved with two bearings. The inner wall of the handle is fixedly connected to the spacer. The spacer is located between the outer rings of the two bearings. The two ends of the spacer respectively abut against the outer rings of the two bearings. The screw passes through the baffle cover and enters the handle. The lower part of the handle is connected to the baffle cover by the screw. The baffle cover and the lower bearing are clearance-matched. The inner ring of the upper bearing abuts against the step shaft A. The lower part of the step shaft B is fixedly connected to the step shaft C. The step shaft C passes through the baffle cover. The step shaft C and the baffle cover are clearance-matched. The end of the step shaft C is fixedly connected to the hand crank;

[0007] The outer wall of the inner ruler tube has an arc protrusion, which is arranged along the axial direction of the inner ruler tube. The inner wall of the outer ruler tube has an arc groove, which is arranged along the axial direction of the outer ruler tube. The arc protrusion is in the arc groove and slides with the arc groove.

[0008] The upper part of the inner ruler tube is fixedly connected to a limiting cap, the outer diameter of the limiting cap is the same as the outer diameter of the outer ruler tube, and the outer wall of the inner ruler tube has a scale line A.

[0009] The outer wall of the outer ruler cylinder has a scale mark B, and the zero position mark of the scale mark B of the outer ruler cylinder is located at the top.

[0010] Beneficial effects of the utility model:

[0011] Since the pitch of the lead screw is the same, the length of the inner ruler tube extended is consistent every time the lead screw rotates one circle. The induction coil records the angle and number of rotations of the permanent magnet block, and the precise length of the inner ruler tube extended can be calculated through the counting chip to ensure measurement accuracy. At the same time, the inner and outer ruler tubes can also be used as ordinary measuring rulers. When the limit cap presses against the measured end point, the display shows the measurement result.

The counting chip is connected to the induction coil 6 by a wire.

[0019] The lower part of the stepped shaft A15 is fixedly connected to the stepped shaft B16. The diameter of the stepped shaft B16 is smaller than that of the stepped shaft A15. The outer wall of the stepped shaft B16 is sleeved with two bearings 20. The inner wall of the handle 4 is fixedly connected to the spacer 18. The spacer 18 is located between the outer rings of the two bearings 20. The two ends of the spacer 18 respectively abut against the outer rings of the two bearings 20. The screw passes through the block cover 7 and enters the handle 4. The lower part of the handle 4 is connected to the block cover 7 by the screw. The block cover 7 is clearance-fitted with the lower bearing 20. The inner ring of the upper bearing 20 abuts against the stepped shaft A15. The lower part of the stepped shaft B16 is fixedly connected to the stepped shaft C17. The stepped shaft C17 passes through the block cover 7. The stepped shaft C17 is clearance-fitted with the block cover 7. The end of the stepped shaft C17 is fixedly connected to the hand crank 8.

[0020] The outer wall of the inner ruler tube 2 has an arc protrusion 10, which is arranged along the axial direction of the inner ruler tube 2. The inner wall of the outer ruler tube 1 has an arc groove 11, which is arranged along the axial direction of the outer ruler tube 1.
