Description
Technical Field
The invention relates to the field of auxiliary tools for building construction, in particular to a marking lamp.
Background
In the building or decoration process, sometimes, a reference straight line needs to be temporarily drawn on a wall body to research the reasonability of the design layout or the standard reaching degree of a construction object. At present, for the temporary reference straight line, either the original perpendicular bisector is adopted for reference drawing, or a laser line marking instrument which has higher cost and larger volume and is not very flexible is adopted for marking; due to the complexity and variety of construction sites, more flexible and compact tools are generally required.
Disclosure of Invention
Aiming at the problems, the invention aims to provide a multifunctional building marking lamp which is small, exquisite, light and portable and can mark straight lines on a building wall at any time; meanwhile, the dynamic spiral line can be easily marked on the building wall.
The technical scheme adopted by the invention for solving the technical problems is as follows: the multifunctional building marking lamp comprises a circular rotating base and a circular turntable which are assembled on the same base shaft; the rotary base and the rotary disc can freely rotate around the base shaft; a light beam lamp which can generate a linear light beam parallel to the axis of the base shaft and facing the rotary disc is arranged on the rotary base and close to the outer edge; the turntable is provided with an annular lens coaxial with the turntable, and the annular lens deflects the linear light beams emitted by the light beam lamps radially outwards away from the axis of the base shaft; and the virtual focal length of the annular lens varies continuously around the circumferential direction.
Preferably, the minimum virtual focal length of the annular lens is less than 5cm, and the maximum virtual focal length is greater than 10 m; further, the virtual focal length of the annular lens starts from the minimum and goes around a half cycle, the virtual focal length increases from the minimum to the maximum, and goes around a half cycle again, and the virtual focal length decreases from the maximum to the minimum.
Preferably, two bubble levelers with mutually vertical axes are arranged on the back surface of the rotating base; when one of the bubble levels is in a horizontal state, the linear light beam of the light beam lamp is positioned in the vertical middle tangent plane of the rotating base.
Preferably, the rotating base is pivoted to a fixed base behind the rotating base, the fixed base has a flat lower bottom surface, and the highest part above the fixed base is not higher than the upper edges of the rotating disc and the rotating base, so that the hands of a user can hold the fixed base while fingers are caught on the upper edges of the rotating disc and the rotating base.
The invention has the beneficial effects that: when the multifunctional building marking lamp works, if a reference straight line needs to be marked on a wall body, only the rotating base needs to be fixed, namely the light beam lamp is fixed, and the turntable is turned, so that the degree of radial outward deflection of the linear light beam of the light beam lamp is continuously changed due to continuous change of the virtual focal length of the annular lens, and the linear light beam continuously moves on the opposite wall body along the straight line (namely the radial direction of the annular lens) to form the reference straight line; when the turntable is held and the rotary base is turned, the linear light beam generated by the light beam lamp has radial motion and rotary motion, so that a dynamic spiral line pattern can be formed on the opposite wall, and the turntable has high enjoyment and can make constructors relax.

Detailed Description
In the embodiment shown in fig. 1-3, the utility building marking light comprises a circular rotating base 2 and a circular turntable 3 mounted on the same base shaft 1; the rotating base 2 and the rotating disc 3 can freely rotate around the base shaft 1; a light beam lamp 4 which can generate a linear light beam parallel to the axis of the base shaft and facing the rotary disc 3 is arranged on the rotary base 2 and close to the outer edge; an annular lens 30 coaxial with the turntable is arranged on the turntable 3, and the annular lens 30 deflects the linear light beams emitted by the light beam lamp 4 radially outwards away from the axis of the base shaft 1; moreover, the virtual focal length (i.e. the distance between the f point and the center of the turntable 3 in fig. 1) of the annular lens 30 continuously changes around the circumferential direction, i.e. the annular lens 30 is a concave lens with continuous zooming in the circumferential direction.
The marking lamp, the minimum virtual focal length of the annular lens 30 is less than 5cm, and the maximum virtual focal length is more than 10 m; therefore, the difference between the maximum deflection angle and the minimum deflection angle of the straight line light of the light beam lamp 4 is large, and the light spot projected on the wall after the straight line light is deflected has a large variation range. Namely, a spiral line with a larger area or a reference straight line with a larger length can be formed.
Further, the virtual focal length of the annular lens 30 starts at the minimum and goes around half a circle, the virtual focal length increasing from the minimum to the maximum, and goes around half a circle again, the virtual focal length decreasing from the maximum to the minimum. Therefore, when the rotary base 2 rotates continuously, after the linear light of the light beam lamp 4 is deflected dynamically, dynamic spiral light which firstly rotates from the inner circle to the outer circle and then rotates from the outer circle to the inner circle can be formed on the wall, and the rotary base has richer and continuous artistic expression effects.
In addition, in the embodiment, two bubble levels 6a and 6b with mutually vertical axes are arranged on the back surface of the rotating base 2; when one of the bubble levels 6b is in a horizontal state, the linear light beam of the light beam lamp 4 is in the vertical middle tangent plane of the rotating base 2. Therefore, when the rotary base 2 is fixed and the bubble level device 6b is in a horizontal state, the rotary disc 3 is rotated, and a vertical reference straight line can be drawn on the opposite wall; and when the bubble leveler 6a is in a horizontal state, a horizontal reference line can be drawn on the opposite wall.
In addition, the rotating base 2 is coupled to a fixed base 5 behind the rotating base 2, the fixed base 5 has a flat lower bottom surface, and the highest part above the fixed base 5 is not higher than the upper edges of the rotating disc 3 and the rotating base 2, so that the hands of a user can hold the fixed base 5 and simultaneously, fingers can be hitched on the upper edges of the rotating disc 3 and the rotating base 2. The fixing base 5 can facilitate fixing the rotating base 2 on the ground.
When the multifunctional building marking lamp works, if a reference straight line needs to be marked on a wall body, only the rotating base 2 needs to be fixed, namely the light beam lamp 4 is fixed, and the turntable 3 is turned, because the virtual focal length of the annular lens 30 is continuously changed, the degree of the radial outward deflection of the annular lens on a straight line light beam of the light beam lamp 4 is continuously changed, so that the straight line light beam continuously moves along the straight line (namely the radial direction of the annular lens) on the opposite wall body to form the reference straight line; when the turntable 3 is held and the rotary base 2 is turned, the linear light beam generated by the light beam lamp 4 has not only radial motion generated by continuous change of the deflection rate, but also rotary motion, so that a dynamic spiral line pattern can be formed on the opposite wall, and the rotary base has high appreciation and can make constructors relax.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
