Description

Technical Field

[0001] This utility model belongs to the field of level technology, specifically relating to a multifunctional level with adjustable laser line angle. Background Technology

[0002] Laser levels are commonly used measuring tools in civil construction, decoration, and installation. Existing levels typically consist of a main body containing a power supply and a laser head; the laser head and main body work together to facilitate measurement and position calibration. A patent with publication number CN219736379U discloses a easily portable level detector, including a digital display laser level main body with an extension end inserted at one end. Both the extension end and the main body have elongated strips at their top and bottom. However, the light source of this existing level detector cannot rotate relative to the main body, meaning the rotation angle of the light source cannot be adjusted independently, limiting its application and resulting in poor versatility. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a multifunctional level with an adjustable laser line angle. The level features a rotatable light source assembly on the main body of the level, which can maintain any rotation angle, making it convenient to use and highly versatile.

[0004] The objective of this invention is achieved through the following technical solution: a multifunctional level with adjustable laser line angle, comprising a level body, an adapter fixedly mounted at the end of the level body, a light source assembly rotatably connected to the adapter, the light source assembly comprising a main housing, a laser head body retractable relative to the main housing, a battery pack and a circuit board; an elastic locking component for locking the light source assembly and the adapter, and a hinge pin for hinged connection between the adapter and the light source assembly; a composite sheath fixedly mounted on the main housing, a positioning protrusion on the adapter, and a support portion on the composite sheath, the positioning protrusion and the support portion being adjacent to each other.

[0005] Preferably, the light source assembly further includes a slider, a reset spring, and a mounting plate; the slider is slidably mounted in the main housing, and a laser head body is provided inside the slider; a reset spring is provided between the slider and the main housing; the elastic locking assembly includes a locking switch, and an elastic protrusion is provided on the adapter adjacent to the locking switch; the locking switch is slidably mounted on the adapter.

[0006] Preferably, the sliding member has a detachable mounting plate at its open end, and the laser head body is disposed between the mounting plate and the sliding member; the main housing contains a circuit board and a battery pack, and the battery pack and the laser head body are electrically connected to the circuit board.

[0007] Preferably, the sliding member is slidably installed inside the main box. The outer wall of the sliding member is provided with a strip-shaped groove, and the inner wall of the main box is provided with a strip-shaped protrusion. The strip-shaped protrusion is disposed in the strip-shaped groove, and the outer contour of the strip-shaped protrusion matches the outer contour of the strip-shaped groove. The main box is provided with a first chamber and a second chamber arranged adjacent to each other. The sliding member is disposed in the first chamber, and the circuit board is disposed in the second chamber.

[0008] Preferably, a wire hole is provided between the first chamber and the second chamber; a charging hole is provided on the side of the main body, and a charging interface is provided on the circuit board, with the charging hole and the charging interface being coaxially arranged; a guide groove for installing a reset spring is provided on the sliding member, with one end of the reset spring abutting against the guide groove and the other end of the reset spring abutting against the inner wall of the first chamber.

[0009] Preferably, the adapter has a slot for mounting a locking switch, the slot being positioned directly above the elastic protrusion; the slider has a limiting groove for inserting the locking switch, and the main housing has a first through hole for inserting the locking switch; in the default state, the return spring inside the main housing is compressed, and when the slider is retracted inside the main housing, the locking switch is inserted into the first through hole and the limiting groove; the elastic protrusion can elastically deform relative to the adapter, and the locking switch has a first groove for inserting the elastic protrusion; the outer contour of the elastic protrusion matches the outer contour of the first groove, and in the default state, the end of the elastic protrusion is engaged in the first groove.

[0010] In the default state, the elastic locking component is locked, and the slider and laser head body are retracted within the first chamber. At this time, the return spring is compressed, and the end of the locking switch is inserted into the limiting groove and the first through hole, preventing the main housing from rotating relative to the adapter. Simultaneously, the elastic protrusion on the adapter engages in the first groove of the locking switch, preventing it from sliding freely forward or backward. The locking groove provides lateral limit to the locking switch, allowing it to slide only forward and backward. When the laser head body needs to be used, the operator pushes the locking switch, overcoming the elastic force of the protrusion, and the end of the locking switch disengages from the first through hole and the limiting groove. At this point, both the main housing and the slider are no longer limited, and the slider, under the action of the return spring, slides out of the main housing along the axis of the strip protrusion. The strip protrusion and groove limit the movement path of the slider, ensuring its reliable ejection from the main housing. Because the outer edge of the main housing is equipped with a synthetic sheath, which is a one-piece molded plastic rubber-coated structure, with a plastic inner layer and a rubber outer layer, the rubber component provides damping. This prevents the main housing from rotating freely relative to the adapter; the operator must push the main housing to rotate it. A wire hole facilitates the insertion and installation of the laser head's wires from the first chamber to the second chamber, allowing for easy electrical connection of the laser head to the circuit board. Charging ports and interfaces facilitate battery charging, and the level can be used repeatedly for extended periods. To relock the light source assembly, push the locking switch to return it to its initial position, then rotate the main housing to return it to its initial horizontal position. Next, press the sliding component into the first chamber; then release the locking switch, which will engage with the limiting groove and the first through hole, restoring the elastic locking component to its default initial state.

[0011] Preferably, the main box body has a synthetic sleeve fixedly connected to the edge near the ruler body. The synthetic sleeve is a one-piece molded plastic coated with rubber. The main box body has a pair of metal connecting rods, and a pin is inserted in the adapter. One end of the metal connecting rod is fixedly connected to the main box body, and the other end of the metal connecting rod is rotatably connected to the pin.

[0012] Preferably, the synthetic sheath has a rotating part, which is arc-shaped; the adapter has a concave part facing the rotating part, which is interference-fitted with the rotating part; the outer layer of the adapter near the pin has several positioning protrusions, which are facing the concave part; the synthetic sheath has a support part facing the positioning protrusions, which fits against the positioning protrusions when the main box is rotated.

[0013] Preferably, in the default state, the upper surface of the main box is flush with the upper surface of the ruler body, and the rotation angle of the main box relative to the ruler body is in the range of 0-90 degrees.

[0014] The synthetic sheath is a one-piece molded design with rubber covering plastic. The inner layer of the synthetic sheath is a plastic component, and the outer layer is a rubber component. The plastic component has rigidity, while the rubber component provides cushioning and damping. A metal connecting rod is incorporated here to strengthen the connection between the adapter and the main housing. By default, the elastic locking component is locked, and the laser head and sliding component are retracted. At this time, the support on the synthetic sheath is adjacent to the positioning protrusion on the adapter. When the main housing rotates to any position, the positioning protrusion is always in contact with the support. Furthermore, the rotating part on the synthetic sheath and the concave part on the adapter are interference-fitted, with the outer contours of the rotating part and the concave part matching each other. This ensures that the main housing maintains a corresponding rotation angle relative to the adapter when rotating at any angle. By incorporating a pin with metal connecting rods at both ends and a synthetic sheath covering the outer layer of the metal connecting rods, the synthetic sheath provides axial positioning of the pin. The pin no longer requires external parts for fixation, facilitating the assembly of the main housing and the adapter. When the main housing operates within the 0-90 degree rotation range, the positioning protrusion works in conjunction with the support to position the main housing, thus maintaining it at the corresponding rotation angle. Simultaneously, the rotating part and the pin are eccentrically positioned, resulting in greater pressure between the positioning protrusion and the support when the main housing rotates. This further stabilizes the main housing at the corresponding rotation angle, preventing the laser head from deflecting during testing.

[0015] Compared with the prior art, this utility model has the following advantages: 1. The laser head body is installed inside the sliding member, and the sliding member can retract relative to the main box body; when the main box body rotates relative to the adapter, the sliding member can automatically pop out from the main box body, and the laser head body can start working immediately, resulting in a better user experience; 2. The main box body and the sliding member can be locked simultaneously by the elastic locking component, which makes it convenient for the operator to switch the working state of the laser head body; 3. A composite sleeve is set on the main box body, and the composite sleeve and the adapter are interference-fitted. In this way, the positioning protrusion on the adapter and the support part on the composite sleeve cooperate with each other, so that the main box body can be maintained at the corresponding rotation angle, which improves versatility; 4. The light source assembly includes the laser head body, which can generate a laser line when passing through. Since the light source assembly can rotate relative to the main box body, the angle of the laser line generated by the laser head body can be easily adjusted. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figures 1 to 10 As shown, this embodiment discloses a multifunctional level with adjustable laser line angle, including a level body 1. An adapter 2 is fixedly installed at the end of the level body 1. A light source assembly 3 is rotatably connected to the adapter 2. The light source assembly 3 includes a main housing 31, and a laser head body 32 that can extend and retract relative to it is provided inside the main housing 31. A battery pack 4 and a circuit board 5 are also provided inside the main housing 31. An elastic locking component 6 is provided between the light source assembly 3 and the adapter 2 for locking the two together. A pin 7 is provided between the adapter 2 and the light source assembly 3 to hinge the two together. A synthetic sheath 8 is fixedly installed on the main housing 31. A positioning protrusion 201 is provided on the adapter 2. A support part 81 is provided on the synthetic sheath 8. The positioning protrusion 201 and the support part 81 are arranged adjacent to each other.

[0018] The light source assembly 3 further includes a slider 33, a return spring 34, and a mounting plate 35. The slider 33 is slidably mounted inside the main housing 31, and a laser head body 32 is disposed inside the slider 33. A return spring 34 is disposed between the slider 33 and the main housing 31. The elastic locking assembly 6 includes a locking switch 61. An elastic protrusion 202 adjacent to the locking switch 61 is provided on the adapter 2. The locking switch 61 is slidably mounted on the adapter 2. A detachable mounting plate 35 is provided at the open end of the slider 33. The laser head body 32 is disposed between the mounting plate 35 and the slider 33. A circuit board 5 and a battery pack 4 are disposed inside the main housing 31. The battery pack 4 and the laser head body 32 are both electrically connected to the circuit board 5. The sliding member 33 is slidably installed inside the main box 31. A strip-shaped groove 36 is provided on the outer wall of the sliding member 33, and a strip-shaped protrusion 37 is provided on the inner wall of the main box 31. The strip-shaped protrusion 37 is disposed within the strip-shaped groove 36, and its outline matches the outline of the strip-shaped groove 36. The main box 31 contains an adjacent first chamber 9 and a second chamber 10. The sliding member 33 is disposed within the first chamber 9, and the circuit board 5 is disposed within the second chamber 10. A wire-passing hole 11 is provided between the first chamber 9 and the second chamber 10. A charging port 12 is provided on the side of the main box 31, and a charging interface 13 is provided on the circuit board 5. The charging port 12 and the charging interface 13 are coaxially arranged. The sliding member 33 has a guide groove 38 for mounting a reset spring 34. One end of the reset spring 34 abuts against the guide groove 38, and the other end abuts against the inner wall of the first chamber 9. The adapter 2 has a slot 203 for mounting the locking switch 61, which is located directly above the elastic protrusion 202. The sliding member 33 has a limiting groove 39 for inserting the locking switch 61, and the main housing 31 has a first through hole 310 for inserting the locking switch 61. In the default state, the return spring 34 in the main housing 31 is in a compressed state. When the sliding member 33 is retracted into the main housing 31, the locking switch 61 is inserted into the first through hole 310 and the limiting groove 39. The elastic protrusion 202 can elastically deform relative to the adapter 2. The locking switch 61 has a first groove 62 for inserting the elastic protrusion 202. The outer contour of the elastic protrusion 202 matches the outer contour of the first groove 62. In the default state, the end of the elastic protrusion 202 is stuck in the first groove 62.

[0019] The main box 31 has a synthetic sleeve 8 fixedly connected to the edge near the ruler body 1. The synthetic sleeve 8 is integrally molded with rubber-coated plastic. The main box 31 has a pair of metal connecting rods 14, and a pin 7 is inserted inside the adapter 2. One end of the metal connecting rod 14 is fixedly connected to the main box 31, and the other end of the metal connecting rod 14 is rotatably connected to the pin 7. The synthetic sleeve 8 has a rotating part 82, which is arc-shaped. The adapter 2 has a concave part 204 facing the rotating part 82, and the concave part 204 is interference-fitted with the rotating part 82. The outer layer of the adapter 2 near the pin 7 has several positioning protrusions 201, which face the concave part 204. The synthetic sleeve 8 has a support part 81 facing the positioning protrusions 201. When the main box 31 is rotated, the support part 81 fits against the positioning protrusions 201. By default, the upper surface of the main box 31 is flush with the upper surface of the ruler body 1, and the rotation angle of the main box 31 relative to the ruler body 1 is in the range of 0-90 degrees.

[0020] The specific operation process of this embodiment is as follows: In the default state, the elastic locking component 6 is in a locked state, and the sliding member 33 and the laser head body 32 are retracted and disposed in the first chamber 9; at this time, the reset spring 34 is in a compressed state, and the end of the locking switch 61 is inserted into the limiting groove 39 and the first through hole 310, so that the main box 31 cannot rotate relative to the adapter 2. At the same time, the elastic protrusion 202 on the adapter 2 is stuck in the first groove 62 of the locking switch 61, so that the locking switch 61 will not slide back and forth arbitrarily. By setting the slot 203, the locking switch 61 is limited to the left and right, so that the locking switch 61 can only slide back and forth. When the laser head body 32 needs to be used, the operator pushes the locking switch 61, so that the locking switch 61 will overcome the elastic force of the elastic protrusion 202, and the end of the locking switch 61 will disengage from the first through hole 310 and the limiting groove 39. At this time, the main box 31 and the sliding member 33 lose their limits, and the sliding member 33 slides out from the main box 31 along the axis of the strip protrusion 37 under the action of the return spring 34. Here, the strip protrusion 37 and the strip groove 36 are set to limit the movement path of the sliding member 33, so that the sliding member 33 can reliably pop out from the main box 31. Because the outer edge of the main housing 31 is provided with a synthetic sheath 8, which is a one-piece molded plastic rubber-coated plastic sheath 8, with a plastic inner layer and a rubber outer layer, the rubber has a damping effect. This prevents the main housing 31 from rotating freely relative to the adapter 2, requiring the operator to push the main housing 31 to rotate it. The wire hole 11 facilitates the insertion and installation of the laser head body 32's wires from the first chamber 9 into the second chamber 10, allowing for convenient electrical connection of the laser head body 32 to the circuit board 5. By setting the charging port 12 and charging interface 13, it is convenient to charge the battery pack 4, and the level can be used repeatedly for a long time. When it is necessary to relock the light source assembly 3, push the locking switch 61 to reset it to the initial position, then rotate the main box 31 to reset it to the initial horizontal position, and then press the sliding member 33 into the first chamber 9. Then release the locking switch 61, so that the locking switch 61 will be locked into the limiting groove 39 and the first through hole 310, thereby restoring the elastic locking assembly 6 to the default initial state.

[0021] The synthetic sheath 8 is a one-piece molded plastic-coated rubber structure. The inner layer of the synthetic sheath 8 is plastic, and an outer layer of rubber is wrapped around the plastic. The plastic provides rigidity, while the rubber provides cushioning and damping. A metal connecting rod 14 is provided to strengthen the connection between the adapter 2 and the main housing 31. In the default state, the elastic locking component 6 is locked, and the laser head body 32 and the sliding component 33 are retracted. At this time, the support portion 81 on the synthetic sheath 8 is adjacent to the positioning protrusion 201 on the adapter 2. When the main housing 31 rotates to any position, the positioning protrusion 201 is always in contact with the support portion 81. Furthermore, the rotating portion 82 on the synthetic sheath 8 is interference-fitted with the concave portion 204 on the adapter 2, and the outer contour of the rotating portion 82 matches the outer contour of the concave portion 204. Thus, when the main housing 31 rotates at any angle, it can maintain the corresponding rotation angle relative to the adapter 2. By setting a pin 7 and installing metal connecting rods 14 at both ends of the pin 7, and setting a composite sheath 8 on the outer layer of the metal connecting rods 14, the composite sheath 8 can axially limit the pin 7. The pin 7 does not need to be fixed with external parts, which facilitates the assembly of the main housing 31 and the adapter 2. When the main housing 31 works in the rotation range of 0-90 degrees, the positioning protrusion 201 can cooperate with the support part 81 to position the main housing 31, so that the main housing 31 can be maintained at the corresponding rotation angle. At the same time, the rotating part 82 is eccentrically set with the pin 7. When the main housing 31 rotates, the pressure between the positioning protrusion 201 and the support part 81 is greater, so that the main housing 31 is more stable in maintaining the corresponding rotation angle and avoids the laser head body 32 from deflecting during testing.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
