Description

Technical Field

[0001] This application relates to laser levels, and more particularly to laser levels with a rotating base. Background Technology

[0002] A laser level is an optical leveling and plumb line calibration device, generally consisting of a housing, a plumb bob suspended within the housing, and a laser generator mounted on the plumb bob. Because operators need to level the surface using different height references during operation, height adjustment components such as tripods are often used. However, users often need to prepare their own suitable height adjustment components, which is inconvenient. Laser levels with built-in height adjustment bases are also available on the market, but these products are bulky and inconvenient to store and carry.

[0003] Therefore, it is necessary to improve and optimize the technical problems existing in the prior art. Summary of the Invention

[0004] The main problem this application aims to solve is that laser levels with attached bases are inconvenient to store and carry.

[0005] To address the aforementioned technical problems, this application provides a laser level, comprising: a housing; a laser generator located within the housing and capable of generating a downward vertical beam emitted to the outside of the housing and / or a laser surface containing the downward vertical beam; a base pivotally mounted to the housing and having an attachment portion for external mounting; the housing having a lower opening for the downward vertical beam and / or laser surface to be emitted, and forming a clearance space below the lower opening and above the bottom surface; the base being rotatable relative to the housing between a first position and a second position; when the base is in the first position, the attachment portion is positioned within the clearance space.

[0006] This application uses the clearance space below the lower opening as a storage area for the attachment part, making full use of the design space of the existing laser level, resulting in a compact structure that is easy to transport and carry. Attached Figure Description

[0017] The following is in conjunction with the appendix Figures 1 to 9 The specific embodiments of the laser level 100 of this application are described in detail.

[0018] The laser level 100 includes a housing 10; a laser generator 20 located within the housing 10 (specifically mounted on a pendulum body within the housing 10) and capable of generating a downward vertical beam S1 emitted to the outside of the housing 10 and / or a laser surface containing the downward vertical beam S1; a base 30 pivotally mounted to the housing 10 and having an attachment portion 301 for external mounting; the housing 10 has a lower opening 101a for the downward vertical beam and / or laser surface to be emitted, and a clearance space 40 is formed below the lower opening 101a and above the bottom surface 102; the base 30 is rotatable relative to the housing 10 between a first position and a second position; when the base 30 is in the first position, the attachment portion 301 is placed in the clearance space 40. The base 30 also has at least one second position, and the base 30 is pivotable relative to the housing 10, converting between the first position and several second positions. The basic function of the clearance space 40 is to avoid the emission path of the lower vertical beam or laser surface. In this application, the clearance space 40 below the lower opening 101a is used as the storage area for the attachment part 301, making full use of the design space of the existing laser level. The structure is compact, convenient for transportation, and not easily damaged. In this embodiment, the attachment part 301 is a magnetic attachment, so it can be flexibly attached to metal surfaces at different heights. Of course, in some other embodiments, the attachment part 301 can also be a fixing clip, a fixing hole, or other possible forms, which will not constitute a special limitation on the scope of protection of this application. Furthermore, in addition to generating the lower vertical beam S1 and / or the laser surface containing the lower vertical beam S1, this application can also generate other laser reference planes, such as the horizontal beam S2 and the upper vertical beam S3 emitted to the outside. Correspondingly, the sill 101 has a side opening 101b and an upper opening 101c for the horizontal beam to be emitted.

[0019] Please refer to the accompanying drawings. A cantilever window 101 protrudes from one side of the housing 10. A lower opening 101a is disposed within the cantilever window 101. The projection of the cantilever window 101 in the vertical direction covers the attachment portion 301 in the first position. Specifically, in this embodiment, a top view of the base 30 in the first position shows that the base 30 and its attachment portion 301 are completely covered by the housing 10 and its cantilever window 101, visually demonstrating the compact design and storage effect. The attachment portion 301 is fixed to the base 30 and has an attachment surface 3011. When the base 30 is in the first position, the cantilever window 101 has an outer wall 1011 that is generally flush with the attachment surface 3011. This design utilizes the attachment portion 301 to secure the laser level in its packaging or storage, for example, by installing a row of metal strips (not shown) on the lower side of the packaging box for securing the attachment portion 301. Furthermore, the base 30 is non-removably assembled to the housing 10, thereby avoiding loss and damage from frequent disassembly and assembly. This also provides the possibility for subsequent installation of locking structures and vibration damping designs on the mating surfaces of the housing 10 and the base 30. It should be noted that "non-removable" here refers to the fact that disassembly is not required during normal use, and does not mean that disassembly is absolutely impossible during maintenance, repair, or other special circumstances.

[0020] The laser level 100 has a locking structure for locking the base 30 in a first position. The base 30 is attached to the bottom surface 102 of the housing 10. The locking structure includes a resilient pin 302 disposed on the base 30 and a receiving recess 1021 disposed on the bottom surface 102 for receiving the resilient pin 302. In addition to the receiving recess 1021 disposed at the first position, the base 30 can also be locked in at least one preset second position within the pivoting range by the locking structure to lock and maintain certain specific positions. When the base 30 is in the second position, the attachment portion 301 moves away from the clearance space 40, thereby opening the emission path of the lower vertical beam S1 and / or the laser surface containing the lower vertical beam S1.

[0021] The housing 10 has a pivot shaft P for the base 30 to pivot. The laser level 100 also has a vibration damping isolator 50. The vibration damping isolator 50 includes an inner bushing 501 sleeved on the pivot shaft P and an outer bushing 503 embedded in the base 30. The inner bushing 501 and the outer bushing 503 are connected only by a number of ribs 505 distributed in the circumferential direction. This design, where the connection is only through a number of ribs 505 and the rest is hollow, blocks or reduces the transmission of vibration, which can slow down the transmission of vibration from the base 30 to the housing 10 when it is impacted. In this embodiment, the inner bushing 501, the outer bushing 503, and the number of ribs 505 are integrally injection molded. A damping material (such as a TPE rubber ring) can also be embedded between the inner bushing 501 and the outer bushing 503 to reduce the burden on the number of ribs 505 and at the same time help to achieve a better damping effect. The pivot shaft P is disposed on the housing 10, the periphery of the vibration damping isolator 50 is fixed to the base 30, and the middle part of the vibration damping isolator 50 is fixed to the pivot shaft P. The vibration damping isolator 50 is elastically fixed to the pivot shaft P by a spring washer 509. The metal spring washer 509, in conjunction with the vibration damping isolator 50, can better achieve vibration reduction, reduce the impact on the built-in precision laser generator 20 when the base 30 is subjected to external force, and at the same time ensure that the relative position between the housing 10 and the base 30 does not shift.

[0022] The above specific embodiments are only used to illustrate this application and are not intended to limit this application. For example, as mentioned earlier, the laser rangefinder of this application can generate a laser surface with a downward vertical beam. This does not mean that the laser level can necessarily generate an independent downward vertical beam; it only requires that the laser surface projects downward, that is, that the fan-shaped area of ​​the laser surface covers the downward vertical beam. Furthermore, the laser level has an independent switch 40 for controlling the start and stop of the laser generator. In some other embodiments, the switch 40 can also be omitted, and the rotation of the base 30 relative to the housing 10 (or the switching between the first position and the second position) can be used to achieve this. In addition, when the base described in this application is in the first position, the clearance space below the lower opening is closed, and the entire laser level does not work. However, this does not preclude the possibility that in some other embodiments, such as when the downward vertical beam or a laser surface containing the downward vertical beam is not needed, other calibration laser lines can still be used normally. In this case, the first position can also be used as the second position (i.e., the storage position is also the working position), and there is no absolute conflict between the two. In summary, those skilled in the art can make various changes and modifications without departing from the scope of this application. Therefore, all equivalent technical solutions also fall within the scope of this application, and the scope of patent protection of this application should be defined by the claims.
