Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
The laser measuring apparatus 100 shown in fig. 1 includes: a main housing 11, a rotating housing 12, a first laser emitting device 13, a second laser emitting device 14, an angle measuring device (not shown) and a display device 15.
The main housing 11 is used for mounting the first laser emitting device 13, and the main housing 11 is also used for forming a main exterior part of the laser measuring device 100. The space enclosed by the main housing 11 can also accommodate the first laser emitting device 13, the angle measuring device, the circuit board, and the electronic circuit. The outer surface of the main housing 11 can form at least a support surface for the laser measuring device 100 to rest on a flat table. For example, the main housing 11 is formed with a side supporting surface 111a and a bottom supporting surface 111b, and the side supporting surface 111a and the bottom supporting surface 111b may be perpendicular to each other. The outer surface of the main housing 11 can also form visible windows or openings through which information desired by the user, such as data displayed by the display device 15, can be viewed.
The rotary housing 12 is used for mounting the second laser emitting device 14, and the rotary housing 12 is also connected with the main housing 11 in a rotatable manner with the rotation axis 101 as an axis. The space enclosed by the rotary housing 12 can accommodate the second laser emitting device 14, and when the rotary housing 12 rotates relative to the main housing 11 with the rotation axis 101 as the axis, the second laser emitting device 14 also rotates synchronously with the rotary housing 12.
The first laser emitting device 13 is used for emitting a laser plane or a laser line to a first target, and the first laser emitting device 13 is disposed in the main housing 11. As shown in fig. 1 and 2, the first laser emitting device 13 may emit a substantially fan-shaped laser plane, for example, and when the laser plane is projected onto a plane, a laser line may be formed on the plane, and the laser line may indicate whether a reticle or an object or the like is horizontal during operation.
A second laser emitting device 14 is used for emitting a laser plane or laser line to a second target, the second laser emitting device 14 being arranged within the rotary housing 12. As shown in fig. 2, the second laser emitting device 14 may also emit a substantially fan-shaped laser plane, for example, and when the laser plane is projected onto a plane, a laser line may be formed on the plane, and the laser line may indicate whether the reticle or the object is level during the operation.
The first target and the second target may be two different targets, or may be different positions or the same position on the same target.
In addition, as shown in fig. 2, the rotation axis 101 of the rotary housing 12 is also coplanar with the laser plane or laser line emitted by the first laser emitting device 13, and the rotation axis 101 of the rotary housing 12 is also coplanar with the laser plane or laser line emitted by the second laser emitting device 14.
The angle measuring device is used for detecting the angle formed by the laser plane or laser line emitted by the first laser emitting device 13 and the laser plane or laser line emitted by the second laser emitting device 14. The display device 15 is used for displaying the angle formed by the laser plane or laser line emitted by the first laser emitting device 13 and the laser plane or laser line emitted by the second laser emitting device 14.
Specifically, as shown in fig. 1, the main housing 11 includes: a main body portion 111 and a projection portion 112. The main body 111 is used for mounting the display device 15, and the display device 15 is mounted in a visible window or an opening formed in the main body 111. The main body 111 also has a substantially straight-line structure, and the longitudinal direction of the main body 111 can be considered as the longitudinal extension direction of the straight-line structure.
A projection 112 is provided at one end in the longitudinal direction of the main body portion 111, and the first laser emitting device 13 is accommodated in the projection 112. The protrusion 112 protrudes from the main body 111 in a direction perpendicular to the rotation axis 101 of the rotary case 12, specifically, in a length direction of the main body 111.
The rotary housing 12 may be connected to the projection 112, and the rotation axis 101 of the rotary housing 12 may also pass through the projection 112. Structurally, the rotating housing 12 is generally circular in configuration. The rotary case 12 also protrudes from the main body portion 111 in the direction of the rotation axis 101 of the rotary case 12, and further, the rotary case 12 also protrudes from the main body 11 in this direction. In this way, the user can relatively easily rotate the rotary case 12 without providing an operation projection structure on the outer circumference of the circular structure of the rotary case 12. Wherein, in the direction of the rotation axis 101 of the rotating shell 12, the ratio of the dimension of the rotating shell 12 exceeding the main shell 11 to the height of the main shell 11 in the direction can be more than 0.2, and more specifically, the dimension of the rotating shell 12 higher than the main shell 11 can be more than 5mm, which is more convenient for the operation of the user.
As shown in fig. 3, in a plane perpendicular to the rotation axis 101 of the rotary housing 12, the projection of the edge of the rotary housing 12 in the plane is also located in the projection of the edge of the main housing 11 in the plane, which enables downsizing of the entire laser measuring device 100. Here, for the sake of easy understanding, a plane perpendicular to the rotation axis 101 of the rotary case 12 may be regarded as a paper surface direction in fig. 3.
As further shown in fig. 2, the rotatable housing 12 is now in a reference position relative to the main housing 11. When the rotary housing 12 is located at the reference position, the laser plane or laser line emitted by the first laser emitting device 13 coincides with the laser plane or laser line emitted by the second laser emitting device 14. Specifically, as described above, the first laser transmitter 13 and the second laser transmitter 14 may both emit fan-shaped laser planes, and when the rotary housing 12 is located at the reference position, the planes of the fan-shaped laser planes emitted by them coincide with each other, that is, the planes of the fan-shaped laser planes emitted by them are located in the same plane. Alternatively, it can be understood that the light emitted from the first laser emitting device 13 forms a laser line when projected onto the target plane, and the light emitted from the second laser emitting device 14 forms a laser line when projected onto the target plane, and when the rotary housing 12 is located at the reference position, the straight lines of the laser lines projected onto the target plane respectively coincide.
When the rotary housing 12 is rotated relative to the main housing 11, as shown in fig. 4 and 5, the rotary housing 12 can be rotated to a measurement position, which can be regarded as other positions where the rotary housing 12 is rotated out of the reference position. When the rotary housing 12 is in the measuring position, the laser light plane or laser light line emitted by the first laser emitting device 13 obliquely intersects the laser light plane or laser light line emitted by the second laser emitting device 14.
Specifically, fig. 4 shows a laser surface and a laser line projected on a wall surface facing the direction of the emitted light when the side support surface 111a of the laser measuring apparatus 100 is placed on the table. In the position shown in fig. 4, the rotary housing 12 is in a measuring position relative to the main housing 11, in which the laser light plane emitted by the first laser emitting device 13 and the laser light plane emitted by the second laser emitting device 14 intersect obliquely. Fig. 5 shows a structure of a laser line projected by the laser surveying device 100 of fig. 4 onto a wall surface on the side of the laser emitting device as viewed in the direction D. As shown in fig. 5, the laser line emitted by the first laser emitting device 13 can be adjusted to extend along the horizontal direction, and the laser line emitted by the second laser emitting device 14 is inclined and intersected with the laser line emitted by the first laser emitting device 13 to form an included angle a, so that the included angle between the object on the wall surface and the horizontal plane can be measured, or the included angle between two object lines can be measured, and the angle measurement can be realized.
In this way, the rotary housing 12 is installed on the main housing 11, and in the case where the size of the rotary housing 12 is much smaller than that of the main housing 11, the measurement of the angle by the laser measuring device 100 can still be achieved, so that the size of the laser measuring device 100 is reduced, the weight is light, the operation is simple, the rotary housing 12 does not need to be positioned, and the measurement accuracy is high.
As further shown in fig. 1, the angle measuring device may be communicatively connected to the display device 15, so that when the angle measuring device measures the corresponding angle, the information can be transmitted to the display device 15 and displayed by the display device 15 in time, wherein the display device 15 may be a display screen, such as an L CD display screen or a L ED display screen.
The laser measuring apparatus 100 may further include: a distance measuring device (not shown) and a level indicating device 16. A distance measuring device for measuring a target distance based on the emission light of the laser light emitted to the target by the first laser emitting device 13 or the second laser emitting device 14 may be provided in the main housing 11. The distance measuring device may also be in communication with a display device 15, which may transmit information to a display screen for display when the distance measuring device measures the target distance. The level indicating device 16 may be a bubble device, and specifically, may include a first bubble device capable of indicating whether the laser measuring device 100 is level in a length direction thereof, may further include a second bubble device capable of indicating whether the laser measuring device is level in a width direction perpendicular to the length direction, and may further include a third bubble device capable of indicating whether the laser measuring device is level in a height direction perpendicular to the length direction.
As an alternative, a leveling device (not shown) may be further provided at one or both of the bottom supporting surface 111b and the side supporting surface 111a of the main housing 11. When the level indicating device 16 indicates that the position where the laser measuring device 100 is placed is not flat, adjustment can be performed by the leveling device, thereby improving the accuracy of measurement.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
