Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to an angle measuring instrument for construction. Background Art

[0002] Building angle measurement is an important part of building surveying and mapping, and its application range is very wide, including determining the location of buildings, establishing control networks, etc. Angle measurement is mainly divided into horizontal angle measurement and vertical angle measurement. Horizontal angle measurement is used to determine the plane position of ground points. Specifically, it is done by vertically projecting the direction lines of any two points on the ground onto the horizontal plane, and then measuring the angle formed. This angle is the horizontal angle. The principle of horizontal angle measurement is to place a horizontal disk with a scale on the plumb line passing through the vertex of the angle, and make the center of the disk pass through the plumb line of the vertex of the angle. When measuring, place the theodolite so that the center of the instrument and the center of the station mark are on the same plumb line. After leveling the instrument with the level on the sighting part, make horizontal angle observations.

[0003] A Chinese patent with publication number CN110360981A discloses a positioning measuring ruler for architectural decoration, which integrates a vertical measuring frame, a horizontal measuring frame and a connecting frame, and has significant functional characteristics and practicality. The vertical measuring frame and the horizontal measuring frame of this measuring ruler both adopt a rectangular frame structure with plate-shaped sides, which ensures the stability of the structure and the accuracy of the measurement. The horizontal measuring frame is designed to be two, which are symmetrically installed on both sides of the connecting frame, thereby increasing the flexibility and adaptability of the measurement. By adjusting the angle between the vertical positioning frame and the horizontal positioning frame, this measuring ruler can also realize fixed-point measurement of variable angles, so as to accurately measure and locate specific inclination angles. This flexibility makes it perform well when handling complex decoration tasks. However, in the prior art, it is impossible to measure the inner angle and the outer angle at the same time with the same tool, and it is not convenient enough to measure different angles.

[0031] In this embodiment, the mounting rod 4 is a hollow structure, a slider 5 is slidably installed in the mounting rod 4, a tension spring 29 is fixedly installed at the lower end of the slider 5, and the tension spring 29 is fixedly connected to the bottom of the mounting rod 4. No matter what position the slider 5 is in the mounting rod 4, the tension spring 29 is always in a stretched state.

[0032] The upper end of the mounting rod 4 is open and communicated with the interior of the mounting rod 4. The slider 5 can slide out of the upper end of the mounting rod 4, but in order to ensure measurement, it cannot slide out completely. The upper end of the mounting rod 4 is fixedly equipped with a limit shaft 1 27 and a limit shaft 28. The upper end of the slider 5 is fixedly equipped with a central shaft 24, and a contact plate 1 22 and a contact plate 25 are hinged on the central shaft 24. A slide groove 1 23 is provided on the contact plate 1 22, and the limit shaft 1 27 is located in the slide groove 1 23. When the slider 5 slides, the limit shaft 1 27 limits the contact plate 1 22 through the slide groove 1 23. The contact plate 25 is provided with a slide groove 26, and the limit shaft 28 is located in the slide groove 26. When the slider 5 slides, the limit shaft 28 limits the contact plate 25 through the slide groove 26, thereby controlling the angle between the contact plate 1 22 and the contact plate 25.

[0033] The slider 5 is a hollow structure, and a slide rod 10 slides inside the slider 5. A long spring 11 is fixedly installed at the lower end of the slide rod 10. The long spring 11 is fixedly connected to the lower end of the inner side of the slide rod 10. Chamfers are set on both sides of the upper end of the slide rod 10, and a right-angle recess is set in the middle of the upper end of the slide rod 10. The chamfers and the right-angle recess are used to support the inner and outer corners of the wall for preliminary positioning, so that measurement can be performed more stably.

[0034] A fixing seat 6 is fixed on the slider 5, a fixing groove 7 is arranged on the fixing seat 6, a plurality of scale lines 8 are evenly arranged on the fixing seat 6, the scale line 8 in the middle is the longest and is the standard line, two plug-in components are arranged on the mounting rod 4, the plug-in components can be inserted into the fixing groove 7, the slider 5 is restricted by the fixing groove 7 and the plug-in components and can only slide a short distance equal to the fixing groove 7, and the positions of the two plug-in components are just near the right angle position for measuring the inner angle and the outer angle.

[0035] In this embodiment, the first plug-in assembly includes a positioning seat 12, which is fixedly mounted on the mounting rod 4, a positioning shaft 15 is slidably mounted in the positioning seat 12, a positioning cap 14 is fixedly mounted on the first end of the positioning shaft 15, a positioning spring 13 is fixedly mounted between the positioning cap 14 and the positioning seat 12, the positioning spring 13 is sleeved on the positioning shaft 15, an indicating needle 16 is fixedly mounted on the positioning shaft 15, and the indicating needle 16 is used to indicate the scale. When the indicating needle 16 coincides with the middle scale line 8, the inner sides of the contact plate 12 and the contact plate 25 are just in a vertical state; the second The plug-in assembly includes a positioning seat 19, which is fixedly installed on the mounting rod 4 at a position closer to the limiting shaft 28. A positioning shaft 20 is slidably installed in the positioning seat 19. The first end of the positioning shaft 20 is fixedly rotated with a positioning cap 17. A positioning spring 18 is fixedly installed between the positioning cap 17 and the positioning seat 19. The positioning spring 18 is sleeved on the positioning shaft 20. An indicator needle 21 is fixedly installed on the second end of the positioning shaft 20. The indicator needle 21 indicates the scale. When the indicator needle 21 coincides with the scale line 8 in the middle of the fixed seat 6, the outer sides of the contact plate 1 22 and the contact plate 25 are 270 degrees.

[0036] Working principle: select different handles 1 according to needs and fix them on the lower side of the mounting rod 4, and clamp them in the fixing groove 7 through different components according to needs. The diameters of the positioning shaft 15 and the positioning shaft 2 20 are smaller than the length in the fixing groove 7, and the positioning shaft 15 is clamped in the fixing groove 7. At this time, the tension spring 29 stretches the fixing seat 6, so that the fixing seat 6 tends to approach the lower end of the mounting rod 4, but is restricted by the end of the fixing groove 7 and the positioning shaft 15. At this time, the angle between the contact plate 1 22 and the contact plate 2 25 is slightly less than ninety degrees. The contact plates 1 22 and the contact plates 2 25 are pressed against the two surfaces of the corner. Since the right angle is measured, the contact plates 1 22 and the contact plates 2 25 will be opened, and the slider 5 will slide in the mounting rod 4. When the indicator needle 16 coincides with the middle scale line 8, it means it is exactly a right angle. If it is not a right angle, the indicator needle 16 will coincide with different scale lines 8.
