Description

[0053] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0054] like Figures 1-14 As shown, this utility model discloses a level with an adjustable measuring angle, comprising:

[0055] Ruler body 1, which is a long strip extending from left to right;

[0056] Adjustable horizontal measuring component 2 is located at the right end of the ruler body 1.

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

[0058] Mounting housing 21 is fixedly installed inside the ruler body 1 by embedding;

[0059] The rotating carrier 22 is rotatably mounted on the mounting housing 21 by means of axial two-end snap-fit, and the rotation axis of the rotating carrier 22 is along the front-back direction;

[0060] Adjusting handwheel 23 is rotatably mounted on mounting housing 21 by means of axial two-end snap-fit, and the rotation axis of adjusting handwheel 23 is in the left and right direction;

[0061] An adjustable level 24 is embedded in and fixedly installed in a rotating base 22, so that the rotation of the rotating base 22 can drive the adjustable level 24 to rotate.

[0062] Linkage component 25 is disposed between the rotating base 22 and the adjusting handwheel 23 so that the adjusting handwheel 23 rotates and drives the rotating base 22 to rotate.

[0063] The reading structure 26 is provided on the mounting housing 21 and the rotating base 22 to measure the angle between the length direction of the adjustable level bubble 24 and the length direction of the scale body 1.

[0064] Therefore, the user can rotate the adjusting handwheel 23 to make the rotating carrier 22 rotate in conjunction with the linkage component 25, thereby adjusting the angle of the adjustable level 24. After adjustment, the angle between the length direction of the adjustable level 24 and the length direction of the ruler 1 can be determined through the reading structure 26. Thus, the adjustable level 24 can be adjusted to any angle for use, greatly improving adaptability. Among them, the common usage methods include the following two: The first method is to pre-adjust the adjustable level 24 to a specific angle k1. While keeping the adjustable level 24 stationary, adjust the length direction of the ruler 1 to the position to be measured. By observing whether the bubble in the level is centered, the angle between the measured position and the horizontal plane can be determined to be k1. The second method is to first adjust the ruler 1 to the position to be measured, and then rotate the adjusting handwheel 23 until the bubble in the adjustable 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 adjustment handwheel 23 is designed so that the adjustable bubble level 24 and the reading structure 26 will not be obstructed by the user's hand when the user drives the adjustment handwheel 23 to rotate. That is, there is no need to raise your hand to observe the current reading and the state of the adjustable bubble 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. The main scale 261 is disposed on the rotating base 22 and is circular. The included angle between adjacent scale lines of the main scale 261 is 1°. n°, meaning the smallest division of the main scale 261 is 1. n°, wherein the vernier scale 262 is disposed on the mounting housing 21, and the vernier scale 262 is arranged in an arc shape. The 0° mark of the vernier scale 262 is aligned with the 0° mark of the main scale 261 when the adjustable bubble level 24 is horizontal. The included angle between adjacent scale lines on the vernier scale 262 is a specific 1°. n°, that is, when any line of the main scale 261 is aligned with the zero line of the vernier scale 262, the value shown by this line of the main scale 261 is the angle between the length direction of the adjustable bubble 24 and the length direction of the scale body 1. During measurement, the value shown by this line of the main scale 261 is the angle between the object and the horizontal line. Similarly, when the 0° line of the main scale 261 is aligned with any line of the vernier scale 262, the value shown by this line of the vernier scale 262 is the angle between the length direction of the adjustable bubble 24 and the length direction of the scale body 1. During measurement, the value shown by this line of the vernier scale 262 is the angle between the object and the horizontal line. For example, the specific angle values ​​shown by the lines of the vernier scale 262 are 22.5°, 45°, 75°, etc.

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

[0067] In other embodiments, the vernier scale 262 can be set to unequal angles according to different needs, in order to adapt to the needs of a specific environment.

[0068] In other embodiments, the vernier scale 262 may not need to be set.

[0069] Specifically, the linkage component 25 in this embodiment includes a first bevel tooth 251 and a second bevel tooth 252. The first bevel tooth 251 is integrally formed on the outer periphery of the rotating carrier 22, and the second bevel tooth 252 is integrally formed on one axial end of the adjusting handwheel 23. The first bevel tooth 251 and the second bevel tooth 252 mesh with each other.

[0070] Therefore, the adjustment handwheel 23 rotates in the left-right direction, which in turn drives the rotating carrier 22 to rotate in the front-back direction through the linkage of the first bevel tooth 251 and the second bevel tooth 252.

[0071] Preferably, the adjustment handwheel 23 is located on the right side of the rotating base 22, so that for most right-handed users, the ruler 1 can be held in the desired measurement position by supporting it with the left hand, and then the adjustment handwheel 23 on the right side of the rotating base 22 can be rotated with the right hand. At this time, the right hand is less likely to obstruct the user's field of vision, making it easier to observe.

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

[0073] Specifically, the mounting base 21 is formed by splicing the first half-shell 211 on the front side and the second half-shell 212 on the rear side, so that an assembly cavity 213 is formed inside the mounting base 21. The rotating carrier 22 and the adjusting handwheel 23 are disposed in the assembly cavity 213. The mounting base 21 is provided with a transparent viewing window 214 at the front end of the rotating carrier 22, and the mounting base 21 is provided with an outward protrusion opening 215 for the adjusting handwheel 23 to extend forward.

[0074] Therefore, the transparent viewing window 214 allows the user to observe the reading of the main scale 261 and the status of the adjustable bubble 24, while the outward opening 215 allows the adjustment handwheel 23 to extend outward, making it convenient for the user to drive the adjustment handwheel 23 to rotate.

[0075] Specifically, in this embodiment, a weight-reducing cavity 15 is provided inside the ruler body 1. The ruler body 1 includes a first plate 11 located in front of the weight-reducing cavity 15, a second plate 12 located below the weight-reducing cavity 15, a third plate 13 located behind the weight-reducing cavity 15, and a fourth plate 14 located above the weight-reducing cavity 15. The first plate 11 and the third plate 13 are both perpendicular to the front-back direction, and the width of the first plate 11 is smaller than the width of the third plate 13. The second plate 12 is perpendicular to the vertical direction, and the front side of the width of the second plate 12 is connected to the lower side of the width of the first plate 11, and the rear side of the width of the second plate 12 is connected to the lower side of the width of the third plate 13. The fourth plate 14 is an inclined plate that slopes from the lower front to the upper rear, and the lower side of the width of the fourth plate 14 is connected to the upper side of the width of the first plate 11, and the upper side of the width of the fourth plate 14 is connected to the upper side of the width of the third plate 13, so that the ruler body 1 as a whole is a right trapezoid. In addition, the fourth plate 14 is provided with a length scale 16 on the side near the third plate 13.

[0076] Therefore, in use, by placing the third plate 13 on the plane where the required measurement position is located, and then adjusting it so that the length scale 16 is parallel or coincident with the required measurement position, and since the fourth plate 14 is set at an angle and the length scale 16 is set on the fourth plate 14 close to the third plate 13, the length scale 16 is closer to the required measurement position, so that the user can more accurately align the length scale 16 with the required measurement position and read the value more accurately based on visual judgment.

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

[0078] In addition, in this embodiment, a scribing device 5 is slidably disposed on the ruler body 1 in the left and right direction. The scribing device 5 is provided with a reading part 51 and a positioning part 52. The reading part 51 is in conjunction 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 13 and the fourth plate 14 away from the ruler body 1 for scribing.

[0079] Therefore, the marking device 5 can be positioned more accurately by the cooperation of the reading unit 51 and the length scale 16, and after positioning, the marking unit 52 marks the corresponding position so that the required position can be marked after the level is removed.

[0080] Specifically, the reading section 51 has a racetrack-shaped reading notch 511 extending through it, and a triangular reading pointer 512 protrudes from the peripheral wall of the reading notch 511. Therefore, the area near the reading pointer 512 is delineated by the reading notch 511, allowing the user to quickly identify the approximate reading of the reading pointer 512, and then determine the accurate reading by the specific indication of the reading pointer 512 within the reading notch 511.

[0081] The positioning part 52 is provided with a positioning hole 521 and a V-shaped notch 522. The positioning hole 521 is provided through the positioning part 52, and the V-shaped notch 522 is provided on the side of the positioning part 52 away from the ruler body 1. Therefore, the positioning hole 521 allows the positioning point to be marked at the desired measurement position by passing a marker pen through the positioning hole 521, while the V-shaped notch 522 allows the marking of a V-shaped line at the desired measurement position by moving the marker pen along the edge of the V-shaped notch 522.

[0082] The marking device 5 includes a sliding part 53 disposed on the first plate 11 and an extension part 54 disposed on the fourth plate 14. The sliding part 53, the extension part 54, the reading part 51, and the positioning part 52 are integrally formed and connected in sequence. In addition, the sliding part 53 has a hook-shaped first locking part 531 disposed on the lower side of the width of the first plate 11 and a hook-shaped second locking part 532 disposed on the upper side of the width of the first plate 11. The lower side of the width of the first plate 11 has a downward-opening first locking groove 111 and the upper side of the width of the first plate 11 has an upward-opening second locking groove 112. The first locking part 53... Part 531 is fitted into the first slot 111, and part 532 is fitted into the second slot 112. With the cooperation of the first slot 531 and the first slot 111, and the second slot 532 and the second slot 112, the scribing device 5 slides on the ruler body 1 in the left and right direction. The scribing device 5 is made of a deformable material so that the second slot 532 can be dislodged from the second slot 112 by flipping the positioning part 52 forward. In addition, after the second slot 532 is dislodged from the second slot 112, the scribing device 5 can be disassembled by dislodging the first slot 531 from the first slot 111 by turning it downward.

[0083] In addition, the sliding part 53 is provided with an arc-shaped handle 533 on the front side, and the handle 533 is perpendicular to the left and right direction, so that the user can slide left and right by holding the handle 533.

[0084] The ruler body 1 has detachable end caps 6 at both ends of its length, so that the two ends of the weight reduction cavity 15 can be sealed by the end caps 6.

[0085] In addition, the end cap 6 is provided with an insertion part 61. The outer periphery shape and size of the insertion part 61 are adapted to the periphery shape and size of the sublimation cavity 15 so that the insertion part 61 is inserted into the sublimation cavity 15 for insertion and engagement. After the insertion part 61 is fully inserted into the sublimation cavity 15, it is positioned by the end cap 6 abutting against the ruler body 1.

[0086] In addition, the insertion part 61 extends a first mounting part 62 at one end away from the end cover 6 in a direction away from the end cover 6. When the end cover 6 is assembled to the ruler body 1, the first mounting part 62 is close to the second plate body 12, and four fittings 621 are arranged circumferentially on the upper side of the first mounting part 62. Each fitting 621 has a buckle protrusion 622 protruding outward from the top. Correspondingly, a hole-shaped second mounting part 534 is provided through the middle of the sliding part 53.

[0087] The sliding part 53 is engaged with the ruler body 1 by the first locking part 531 and the second locking part 532 to form a usage state.

[0088] When the sliding part 53 is engaged with the first mounting part 62 via the second mounting part 534, and the end cap 6 is engaged with the ruler body 1, the scribing device 5 is built into the weight reduction cavity 15 to form a storage state.

[0089] Specifically, with the end cap 6 removed from the ruler body 1, the scribing device 5 is adjusted so that the sliding part 53 is at the bottom and the extension part 54 is located on the side of the sliding part 53 away from the end cap 6 and extends upward. Then, the sliding part 53 can be turned downward so that the first mounting part 62 can be inserted into the second mounting part 534. After the engagement is completed, without applying an upward force to the scribing device 5, the snap-fit ​​protrusion 622 can effectively prevent the first mounting part 62 from coming out of the second mounting part 534, thus ensuring the stability of the installation. If it is necessary to remove the scribing device 5 from the end cap 6, an upward force is actively applied to forcibly separate the first mounting part 62 and the second mounting part 534, so that the scribing device 5 can be detachably installed on the end cap 6.

[0090] In addition, when the scribing tool 5 is assembled on the end cap 6, the handle 533 is perpendicular to the front and back direction, so it can be inserted into the gap between the two fittings 621 on the left and the gap between the fittings 621 on the right, thereby providing circumferential limiting to further improve the stability of the scribing tool 5 assembled on the end cap 6.

[0091] Even better, the two assemblies 621 on the left side are provided with reinforcing ribs 623 extending to the left, and the two assemblies 621 on the right side are provided with reinforcing ribs 623 extending to the right. This makes the reinforcing ribs 623 have a circumferential rotation restriction effect on the handle 533. Under the action of the reinforcing ribs 623, the force acting on the assemblies 621 due to the rotation of the handle 533 is reduced, thus protecting the assemblies 621.

[0092] In addition, an unlocking member 63 is slidably provided on the insertion part 61 along the front-back direction. A pressing part 631 is provided at the front end of the unlocking member 63. The pressing part 631 extends forward or retracts backward from the insertion part 61 as the unlocking member 63 slides. In addition, a reset member 64 is provided between the insertion part 61 and the unlocking member 63. The reset member 64 is used to drive the pressing part 631 to extend forward from the insertion part 61. Correspondingly, a locking groove 113 is provided through the first plate 11 along the front-back direction. The pressing part 631 is engaged with the locking groove 113 to prevent the insertion part 61 from dislodging from the weight reduction cavity 15.

[0093] Therefore, when the end cap 6 needs to be assembled onto the body 1, the pressing part 631 is first pressed into the insertion part 61 and kept pressed, and then the insertion part 61 is inserted into the weight reduction cavity 15. When the insertion part 61 is inserted into place, the pressing part 631 and the locking groove 113 are aligned. Under the action of the reset member 64, the pressing part 631 is reset forward with the unlocking member 63, thereby achieving the engagement of the pressing part 631 and the locking groove 113. In addition, when the end cap 6 needs to be removed, the pressing part 631 is first pressed into the insertion part 61 and kept pressed to make the pressing part 631 disengage from the locking groove 113. Then, the insertion part 61 is pulled out from the weight reduction cavity 15. After that, under the action of the reset member 64, the pressing part 631 is reset forward with the unlocking member 63.

[0094] Specifically, the reset component 64 uses a compression spring.

[0095] In addition, in this embodiment, a handle 17 is provided through the middle of the left half of the ruler body 1 in the front-to-back direction.

[0096] In addition, in this embodiment, a first storage groove 18 is provided in the middle of the right half of the ruler body 1, extending to the front surface of the ruler body 1. A first opening and closing cover 181 for opening and closing the first storage groove 18 is slidably provided on the front surface of the ruler body 1. The length direction of the first storage groove 18 and the sliding direction of the first opening and closing cover 181 are both set along the length direction of the ruler body 1.

[0097] Therefore, 1. By setting the first storage slot 18, tools commonly used with a level can be stored in the first storage slot 18, and when not in use, they can be sealed by the first opening and closing cover 181 to ensure stable storage. 2. The lifting and gripping hole 17 is set in the middle of the left half of the ruler body 1, and the first storage slot 18 is set in the middle of the right half of the ruler body 1, making the overall structure more orderly and compact.

[0098] The first opening and closing cover 181 slides to the left to open the first storage slot 18 and slides to the right to close the first storage slot 18. After sliding to the right, the first opening and closing cover 181 is fixed by a buckle.

[0099] In addition, in this embodiment, a pencil sharpener 71, a collection cavity 72, and a second storage slot 73 are provided in the middle of the ruler body 1. The opening of the pencil sharpener 71 is located on the rear surface of the ruler body 1. The collection cavity 72 and the second storage slot 73 both extend to the rear surface of the ruler body 1. A second opening and closing cover 74 for opening and closing the collection cavity 72 and the second storage slot 73 is provided on the ruler body 1. The pencil sharpener 71 is used to cut pencils, the collection cavity 72 is used to collect the shavings cut by the pencil sharpener 71, and the second storage slot 73 is used to place pencils.

[0100] Therefore, the pencil used with the level can be sharpened with the pencil sharpener 71, and the shavings can be collected in the collection chamber 72. When collecting shavings, the collection chamber 72 is sealed by flipping the second opening and closing cover 74 to prevent shavings from falling out. When it is necessary to clean up the shavings, the collection chamber 72 can be opened by flipping the second opening and closing cover 74 to pour out the shavings. In addition, a second storage slot 73 is provided so that the used pencil can be placed in the second storage slot 73 for storage, and the second opening and closing cover 74 can seal the second storage slot 73 to ensure the pencil is stored stably.

[0101] Preferably, an elastic clip 731 is provided in the second storage slot 73 so that the pencil can be held by the elastic clip 731, thereby further improving the storage stability of the pencil.

[0102] The upper end of the second opening and closing cover 74 is provided with a U-shaped reverse part 741. One end of the U-shape of the reverse part 741 is integrally formed and connected to the upper end of the second opening and closing cover 74. The other end of the U-shape of the reverse part 741 is integrally formed and provided with a hinge rod 742. Correspondingly, the ruler body 1 is provided with a hinge slot 75 above the second collection groove, so that the hinge rod 742 extends into the second collection groove and passes through the second collection groove upward, and the hinge is realized through the cooperation of the hinge rod 742 and the hinge slot 75.
