Detailed Description

An embodiment of the laser level 100 of the present application will be described in detail below with reference to fig. 1-9.

The laser level 100 comprises a housing 10; a laser generator 20, which is located inside the housing 10 (specifically, on a pendulum body disposed inside the housing 10) and can generate a lower plumb beam S1 emitted to the outside of the housing 10 and/or a laser plane containing the lower plumb beam S1; a base 30 pivotably assembled to the housing 10 and having an attachment portion 301 for external mounting; the housing 10 has a lower opening 101a for the lower vertical light beam and/or the laser surface to emit, and an abdicating space 40 is formed below the lower opening 101a and above the bottom surface 102, the base 30 can rotate between the first position and the second position relative to the housing 10, and when the base 30 is located at the first position, the attaching portion 301 is arranged in the abdicating space 40. The base 30 also has at least one second position, and the base 30 is pivotable relative to the housing 10 between a first position and a number of second positions. Let a space 40 basic function avoid down plumb light beam or laser face jet out the route, this application will let a space 40 below lower shed 101a as the storage area of attached portion 301, make full use of the design space of current laser level appearance, compact structure, convenient transportation also is difficult for damaging. The attachment portion 301 in this embodiment is a magnetic attachment portion, and thus can be flexibly attached to metal surfaces with different heights, and of course, in other embodiments, the attachment portion 301 may also be a fixing clip, a fixing hole, or other possible forms, and does not particularly limit the scope of the present application. In addition, in the present application, besides the lower vertical beam S1 and/or the laser surface including the lower vertical beam S1, other laser reference planes may also be generated, such as a horizontal beam S2 and an upper vertical beam S3 emitted to the outside, and accordingly, the suspension window 101 has a side opening 101b and an upper opening 101c for emitting the horizontal beam.

With reference to the drawings, a suspending window 101 protrudes from one side of the housing 10, the lower opening 101a is disposed on the suspending window 101, and a projection of the suspending window 101 in a vertical direction covers the attachment portion 301 at the first position. In particular, in the present embodiment, as seen from the top view of the base 30 in the first position, the base 30 and the attachment portion 301 thereof are completely covered by the housing 10 and the suspension window 101 thereof, so that the compact design and the storage effect can be intuitively embodied. The attachment portion 301 is secured to a base 30 and has an attachment surface 3011, and the hung window 101 has an outer side wall 1011 that is generally flush with the attachment surface 3011 when the base 30 is placed in the first position. This design utilizes the attachment portion 301 to secure the encasement or storage of the laser level, such as by mounting a row of metal strips (not shown) on the underside of the encasement to which the attachment portion 301 is secured. In addition, the base 30 is non-detachably assembled to the housing 10, thereby avoiding loss and frequent assembly and disassembly, and providing possibility for subsequent locking structure and vibration damping design on the mating surfaces of the housing 10 and the base 30. It should be noted that non-removable is intended to mean that removal is not required during normal use, and does not represent absolute non-removal for repair, maintenance, or other special circumstances.

The laser level 100 has a locking structure that locks the base 30 in a first position. The base 30 is attached to the bottom surface 102 of the housing 10, and the locking structure includes a resilient thimble 302 disposed on the base 30 and a receiving hole 1021 disposed on the bottom surface 102 for receiving the resilient thimble 302. In addition to the receiving recess 1021 at the corresponding first position, the base 30 can be locked at least at a preset second position by a locking structure in the pivoting section to lock and hold some specific positions. When the base 30 is located at the second position, the attaching portion 301 leaves the relief space 40, thereby opening an emitting path of the lower plumb beam S1 and/or the laser surface including the lower plumb beam S1.

The housing 10 has a pivot axis P for pivoting the base 30, the laser level 100 further has a vibration damping isolating member 50, the vibration damping isolating member 50 includes an inner shaft sleeve 501 sleeved on the pivot axis P and an outer shaft sleeve 503 embedded on the base 30, and the inner shaft sleeve 501 and the outer shaft sleeve 503 are connected only by a plurality of ribs 505 distributed on the circumference. The design that the ribs 505 are connected and the rest parts are hollowed out can obstruct or reduce the transmission of vibration and can slow down the transmission of the base 30 to the shell 10 when the base is collided. The inner shaft sleeve 501, the outer shaft sleeve 503 and the plurality of ribs 505 are molded through integral injection, and a vibration damping material (such as a TPE rubber ring) can be further embedded between the inner shaft sleeve 501 and the outer shaft sleeve 503 to reduce the burden of the plurality of ribs 505 and achieve a better vibration damping effect in an auxiliary manner. The pivot axis P is disposed on the housing 10, the periphery of the vibration damping isolating member 50 is fixed to the base 30, and the middle of the vibration damping isolating member 50 is fixed to the pivot axis P. The vibration damping isolation member 50 is elastically fixed to the pivot axis P by a spring washer 509, and the metal elastic piece 509 is combined with the vibration damping isolation member 50 to better achieve vibration damping, so that the low base 30 impacts the built-in precise laser generator 20 when receiving an external force, and simultaneously, the relative position between the housing 10 and the base 30 is not deviated.

The above detailed description is merely illustrative of the present application and is not intended to limit the present application. For example, it is said that the laser range finder of the present application can generate a laser plane of a plumb-lowering beam, and it is not said that the laser level meter can generate an independent plumb-lowering beam, but it is only required that the laser plane is projected downward, that is, it is only required that the sector of the laser plane covers the plumb-lowering beam. Furthermore, the laser level has a separate switch 40 for controlling the on/off of the laser generator, and in other embodiments, the switch 40 may be omitted and the rotation (or the switching between the first position and the second position) of the base 30 relative to the housing 10 may be used. In addition, when the base is located in the first position, the abdicating space below the lower opening is closed, and the whole laser level does not work, but it cannot be excluded that in other embodiments, for example, when a lower vertical beam or a laser surface including a lower vertical beam is not needed, other calibration laser lines can still be used normally, and then 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 positions. In summary, those skilled in the art can make various changes and modifications without departing from the scope of the present application, and therefore all equivalent technical solutions also belong to the scope of the present application, and the protection scope of the present application should be defined by the claims.
