[0053] To enable those skilled in the art to better understand the present invention and thus more clearly define the scope of protection of the present invention, the present invention will be described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only some specific embodiments of the concept of the present invention and only a part of the embodiments of the present invention. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present invention, and each specific feature does not of course and directly limit the scope of implementation of the present invention. Conventional selections and substitutions made by those skilled in the art under the guidance of the concept of the present invention shall be regarded as being within the scope of protection required by the present invention.

[0054] As Figures 1-14 shown, the present invention discloses a spirit level with adjustable measuring angle, comprising:

[0055] A body 1, the body 1 is in the shape of a long strip extending left and right;

[0056] An adjustable level measuring assembly 2, the adjustable level measuring assembly 2 is arranged at the right end of the body 1.

[0057] Specifically, the adjustable level measuring assembly 2 includes:

[0058] A mounting housing base 21, the mounting housing base 21 is fixedly arranged in the body 1 by an embedding method;

[0059] A rotating carrier 22, the rotating carrier 22 is rotatably arranged in the mounting housing base 21 by a clamping method at both axial ends, and the rotation axis of the rotating carrier 22 is along the front-back direction;

[0060] An adjusting handwheel 23, the adjusting handwheel 23 is rotatably arranged in the mounting housing base 21 by a clamping method at both axial ends, and the rotation axis of the adjusting handwheel 23 is along the left-right direction;

[0061] An adjustable spirit level 24, the adjustable spirit level 24 is fixedly installed in the rotating carrier 22 by being embedded in the rotating carrier 22, so that the rotation of the rotating carrier 22 can drive the adjustable spirit level 24 to rotate;

[0062] A linkage assembly 25, the linkage assembly 25 is arranged between the rotating carrier 22 and the adjusting handwheel 23 so that the rotation of the adjusting handwheel 23 drives the rotation of the rotating carrier 22;

[0063] A reading structure 26, the reading structure 26 is arranged between the mounting housing base 21 and the rotating carrier 22 to measure the angle between the length direction of the adjustable spirit level 24 and the length direction of the body 1.

[0064] Therefore, the user can rotate the adjustment handwheel 23 to drive the rotary carrier 22 to rotate under the action of the linkage assembly 25, so as to adjust the angle of the adjustable spirit level 24. After the adjustment is completed, the angle between the length direction of the adjustable spirit level 24 and the length direction of the scale body 1 can be determined through the reading structure 26. Thus, the adjustable spirit level 24 can be adjusted to any angle for use, greatly improving the adaptability. Among them, the common usage methods include the following two: The first is to pre-adjust the adjustable spirit level 24 to a specific angle k1. Without moving the adjustable spirit level 24, adjust the length direction of the scale body 1 to the position to be measured, and determine whether the angle between the measured position and the horizontal plane is k1 by observing whether the bubble in the spirit level is centered; The second is to first adjust the scale body 1 to the position to be measured, and then rotate the adjustment handwheel 23 until the bubble in the adjustable spirit level 24 is centered. At this time, the reading k2 on the reading structure 26 is the angle between the measured position and the horizontal plane. In addition, the setting of the adjustment handwheel 23 enables the adjustable spirit level 24 and the reading structure 26 not to be blocked by the user's hand when the user drives the adjustment handwheel 23 to rotate, that is, there is no need to raise the hand to observe the current reading and the state of the adjustable spirit level 24, making the adjustment process more convenient.

[0065] Specifically, the reading structure 26 in this embodiment includes a main scale 261 and a vernier scale 262. Among them, the main scale 261 is arranged on the rotary carrier 22, and the main scale 261 is circularly arranged. The angle between adjacent scale lines of the main scale 261 is 1*n°, that is, the minimum scale value of the main scale 261 is 1*n°. Among them, the vernier scale 262 is arranged on the mounting housing 21, and the vernier scale 262 is arc-shaped. The 0° scale line of the vernier scale 262 is aligned with the 0° scale line of the main scale 261 when the adjustable spirit level 24 is in a horizontal state. The angle between adjacent scale lines on the vernier scale 262 is a specific 1*n°. That is, when any scale line of the main scale 261 is aligned with the zero line of the vernier scale 262, the value indicated by this scale line of the main scale 261 is the angle between the length direction of the adjustable spirit level 24 and the length direction of the scale body 1. During measurement, the value indicated by this scale line of the main scale 261 is the angle between the object and the horizontal line. Similarly, when the 0° scale line of the main scale 261 is aligned with any scale line on the vernier scale 262, the value indicated by this scale line of the vernier scale 262 is the angle between the length direction of the adjustable spirit level 24 and the length direction of the scale body 1. During measurement, the value indicated by this scale line of the vernier scale 262 is the angle between the object and the horizontal line. For example, the specific angle values indicated by the scale lines of the vernier scale 262 are 22.5°, 45°, 75°, etc.

[0066] In other embodiments, the main scale 261 can be arranged in an arc shape according to different requirements.

[0067] In other embodiments, the cursor scale 262 can be set to an unequal angle according to different requirements to meet the needs in a specific environment.

[0068] In other embodiments, the cursor scale 262 may not be set either.

[0069] Specifically, the linkage assembly 25 in this embodiment includes a first bevel gear 251 and a second bevel gear 252. The first bevel gear 251 is integrally formed on the outer periphery of the rotating carrier 22, and the second bevel gear 252 is integrally formed at one axial end of the adjusting handwheel 23. The first bevel gear 251 and the second bevel gear 252 are meshed.

[0070] Therefore, when the adjusting handwheel 23 rotates axially in the left - right direction, the rotating carrier 22 axially in the front - back direction is driven to rotate through the linkage of the first bevel gear 251 and the second bevel gear 252.

[0071] Preferably, the adjusting handwheel 23 is located on the right side of the rotating carrier 22. For most users who use their right hand as the dominant hand, the left hand can support the body 1 of the ruler to keep the body 1 in the required measurement position, and then the right hand rotates the adjusting handwheel 23 on the right side of the rotating carrier 22. At this time, the right hand is not likely to block the user's vision, which is convenient for observation.

[0072] Preferably, the modulus ratio of the first bevel gear 251 and the second bevel gear 252 in this embodiment is 3 - 7, so that the rotation amplitude of the rotating carrier 22 driven by one - turn rotation of the adjusting handwheel 23 is smaller, thereby improving the adjustment accuracy.

[0073] Specifically, the mounting housing 21 is formed by splicing a first half - shell 211 at the front side and a second half - shell 212 at the rear side, so that an assembly cavity 213 is formed inside the mounting housing 21. The rotating carrier 22 and the adjusting handwheel 23 are arranged in the mounting cavity. A transparent viewing window 214 is provided at the front end of the mounting housing 21 where the rotating carrier 22 is located, and an outward - extending opening 215 through which a part of the adjusting handwheel 23 protrudes forward is provided on the mounting housing 21.

[0074] Therefore, the setting of the transparent viewing window 214 enables the user to observe the indication of the main scale 261 and the state of the adjustable spirit level 24 inward, and the setting of the outward - extending opening 215 allows a part of the adjusting handwheel 23 to protrude out, which is convenient for the user to drive the adjusting handwheel 23 to rotate.

[0075] Specifically, a mass-reducing cavity 15 is provided inside the body 1 of the ruler. The body 1 of the ruler includes a first plate body 11 on the front side of the mass-reducing cavity 15, a second plate body 12 on the lower side of the mass-reducing cavity 15, a third plate body 13 on the rear side of the mass-reducing cavity 15, and a fourth plate body 14 on the upper side of the mass-reducing cavity 15. Both the first plate body 11 and the third plate body 13 are perpendicular to the front-rear direction, and the width of the first plate body 11 is smaller than the width of the third plate body 13. The second plate body 12 is perpendicular to the vertical direction, and the front side of the width of the second plate body 12 is connected to the lower side of the width of the first plate body 11, and the rear side of the width of the second plate body 12 is connected to the lower side of the width of the third body. The fourth plate body 14 is an inclined plate that slopes from the front lower side to the rear upper side, and the lower side of the width of the fourth plate body 14 is connected to the upper side of the width of the first plate body 11, and the upper side of the width of the fourth plate body 14 is connected to the upper side of the width of the third plate body 13, so that the overall body 1 of the ruler is in the shape of a right trapezoid. In addition, a length scale 16 is provided on the side of the fourth plate body 14 close to the third plate body 13.

[0076] Therefore, when in use, by placing the third plate body 13 on the plane where the position to be measured is located, and then adjusting to make the length scale 16 parallel or coincident with the position to be measured. Among them, since the fourth plate body 14 is inclined, and the length scale 16 is provided at the position of the fourth plate body 14 close to the third plate body 13, so that the length scale 16 is closer to the position to be measured, so that the user can more accurately align the length scale 16 with the position to be measured and read the value more accurately according to visual judgment.

[0077] In addition, a first spirit level 3 and a second spirit level 4 are provided on the body 1 of the ruler in this embodiment. The length direction of the first spirit level 3 is along the left-right direction and parallel to the length direction of the body 1 of the ruler, and the length direction of the second spirit level 4 is along the vertical direction and perpendicular to the length direction of the body 1 of the ruler. Specifically, the first spirit level 3 is provided in the middle of the length of the body 1 of the ruler, the second spirit level 4 is provided at the left end of the body 1 of the ruler, and the adjustable horizontal measuring assembly 2 is provided at the right end of the body 1 of the ruler.

[0078] In addition, a scribing tool 5 is slidably provided on the body 1 of the ruler in the left-right direction. The scribing tool 5 is provided with a reading part 51 and a positioning part 52. The reading part 51 cooperates with the length scale 16 to measure the reading of the current position of the positioning part 52. The positioning part 52 extends upward from the intersection of the third plate body 13 and the fourth plate body 14 and is away from the body 1 of the ruler for scribing use.

[0079] Therefore, the setting of the scribing tool 5 can be more accurately positioned through the cooperation of the reading part 51 and the length scale 16, and after positioning, scribing is performed at the corresponding position through the positioning part 52 to mark the required position after the leveling ruler is removed.

[0080] Specifically, the reading portion 51 is provided with a runway-shaped reading notch 511, and a triangular reading pointer 512 is protruded from the peripheral wall of the reading notch 511. Therefore, the area near the reading pointer 512 is circled by the reading notch 511, so that the user can more quickly identify the approximate reading of the reading pointer 512, and then determine the accurate reading through the specific indication of the reading pointer 512 in the reading notch 511.

[0081] The positioning portion 52 is provided with a positioning hole 521 and a V-shaped notch 522. The positioning hole 521 is provided to penetrate the positioning portion 52, and the V-shaped notch 522 is provided on the side of the positioning portion 52 away from the ruler body 1. Therefore, the positioning hole 521 is provided so that the positioning point can be marked at the position to be measured by passing a marking pen through the positioning hole 521, and the V-shaped notch 522 is provided so that the V-shaped line can be marked at the position to be measured by moving the marking pen along the edge of the V-shaped notch 522.

[0082] The scriber 5 includes a sliding portion 53 arranged on the first plate body 11 and an extension portion 54 arranged on the fourth plate body 14. The sliding portion 53, the extension portion 54, the reading portion 51 and the positioning portion 52 are integrally formed and connected in sequence. In addition, the sliding portion 53 is provided with a first hook-shaped clamping portion 531 at the lower width side of the first plate body 11, and a second hook-shaped clamping portion 532 is provided at the upper width side of the first plate body 11. A first clamping groove 111 opening downward is provided at the lower width side of the first plate body 11, and a second clamping groove 112 opening upward is provided at the upper width side of the first plate body 11. The first clamping portion 531 is provided with a first clamping portion 532 opening upward. The portion 531 is snap-fitted into the first slot 111, and the second portion 532 is snap-fitted into the second slot 112, so that the scriber 5 can slide on the ruler body 1 along the left-right direction under the cooperation of the first portion 531 and the first slot 111 and the second portion 532 and the second slot 112, wherein the scriber 5 is made of a deformable material, so that the positioning portion 52 can be flipped forward to realize the second portion 532 to escape from the second slot 112. In addition, after the second portion 532 escapes from the second slot 112, the scriber 5 can be disassembled by downwardly detaching the first portion 531 from the first slot 111.

[0083] In addition, a handle 533 in the form of an arc sheet is provided at the front side of the sliding portion 53 , and the handle 533 is perpendicular to the left and right directions, so that the user can slide and drive the sliding portion 533 left and right by holding the handle 533 .

[0084] Wherein, end caps 6 are detachably provided at both ends of the length of the ruler body 1 , so that the two ends of the reduced-mass cavity 15 are sealed by the end caps 6 .

[0085] In addition, the end cap 6 is provided with an insertion portion 61. The outer peripheral shape and size of the insertion portion 61 are adapted to the shape and size of the peripheral wall of the mass reduction cavity 15, so as to be inserted into the mass reduction cavity 15 through the insertion portion 61 for plug-in fit, and after the insertion portion 61 is completely inserted into the mass reduction cavity 15, it is positioned by abutting against the body 1 through the end cap 6.
