DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Mount the handheld calibrator on a horizontal member, such as Figure 1-4 As shown, it includes a support frame 1, which is L-shaped as a whole. The support frame 1 serves as the bearing base of the entire device, wherein the support frame 1 includes a vertical plate and a horizontal plate, a horizontal support shaft 2 located above the horizontal plate is installed on one side of the vertical plate, a vertical rocker arm 3 is installed on the horizontal support shaft 2, one end of the vertical rocker arm 3 is sleeved on the horizontal support shaft 2 and can rotate freely around the horizontal support shaft 2, so that the vertical rocker arm 3 can eventually stay in a vertical posture under the action of its own gravity, and a ray emitter 4 is installed at the other end of the vertical rocker arm 3, the axis of the emission port of the ray emitter 4 is perpendicular to the axis of the vertical rocker arm 3, so that the light emitted by the ray emitter 4 is perpendicular to the vertical rocker arm 3 mutually perpendicular horizontal rays, the rays emitted by the ray emitter 4 are used as the calibration reference during the installation of the horizontal component. When in use, the calibrator of the present application is placed at one end of the component (the bottom surface of the horizontal plate is placed in contact with the surface of the component), and with the assistance of the rays emitted by the ray emitter 4, the horizontal posture of the component during installation is adjusted; wherein an emission switch 5 is installed on the support frame 1, and the emission switch 5 is connected to the ray emitter 4 for communication. By triggering the emission switch 5, the ray emitter 4 can be started or shut down. When in use, wireless signal communication control can be adopted to reduce the application of communication cables, improve the neatness of the overall structure, and also facilitate the adaptation to the swing of the vertical rocker arm 3. wherein in order to better ensure that the vertical rocker arm 3 is stable in the vertical direction in the natural state, a counterweight block is provided on the outer wall of the lower end of the vertical rocker arm 3, which helps to stabilize the vertical rocker arm 3 in the vertical state.

[0026] In actual use, the light emitted by the ray emitter 4 is visible light, and a laser emitter or an infrared reflector may be used.

[0027] A shield 6 covering the vertical rocker arm 3 is installed on the support frame 1. The lower end of the vertical rocker arm 3 extends out of the shield 6. The lower end of the shield 6 is an open structure, which can protect the vertical rocker arm 3 and limit the swing amplitude of the vertical rocker arm 3 by the size of its opening. In actual design, a scale 8 in the circumferential direction can be provided on the side wall of the shield 6, and an indicating arrow 14 corresponding to the circumferential scale 8 can be designed on the vertical rocker arm 3. Since the present application is placed on a component for use, if the component is horizontal, the indicating arrow 14 will point to the zero point of the scale 8 when it is in a vertical state. If the component is tilted, since the horizontal plate and the surface of the component are in contact with each other, the entire support frame 1 is also tilted. In this way, the indicating arrow 14 on the vertical rocker arm 3 cannot point to the zero point of the scale 8, but will point to a certain tilt angle. At this time, the indicated angle can be used to assist in judging the angle that needs to be rotated when the component is adjusted, so as to facilitate better adjustment. In order to better observe the corresponding relationship between the indicating arrow 14 and the scale 8, the protective cover 6 is made of a transparent material, so that the situation of the vertical rocker arm 3 inside the protective cover 6 can be clearly observed.

[0028] In order to prevent the friction between the vertical rocker arm 3 and the horizontal support shaft 2 from affecting the vertical posture of the vertical rocker arm 3, the present application provides a lubricating layer 7 (lubricating oil can be used) at the joint between the vertical rocker arm 3 and the horizontal support shaft 2, which can reduce the friction between the two and further facilitate the free swing of the vertical rocker arm 3, so that it can better stay in the vertical direction.

[0029] In order to facilitate the observation of the light emitted by the ray emitter 4 and use it as a calibration reference, the distance between the bottom surface of the horizontal plate and the emission port of the ray emitter 4 in the present application is 2-3 cm. In actual use, the distance between the emitted light and the surface of the component is 2-3 cm. The closer the distance between the two is, the more helpful it is to adjust the component.

[0030] When the component is made of steel or iron, in order to better place the calibrator on one end of the component, the present application embeds a magnet 9 on the bottom wall of the horizontal plate. The end face of the magnet 9 is flush with the bottom surface of the horizontal plate. The adsorption force of the magnet 9 can better place the calibrator on the component, avoiding the problem of easy shaking of the calibrator and improving stability.

[0031] In order to better calibrate the component, the present application also includes a positioning block 10, a magnet 9 is installed at the bottom of the positioning block 10, and a positioning mark is provided on the side wall of the positioning block 10. The distance between the positioning mark and the bottom wall of the positioning block 10 is equal to the distance between the bottom surface of the horizontal plate and the emission port of the ray emitter 4. When in use, the positioning block 10 is installed at the end of the component away from the calibrator and facing the direction of the emitted light. When the light emitted by the ray emitter 4 falls on the positioning mark, the surface component is horizontal, which serves as an adjustment reference and helps to improve the adjustment efficiency. When the positioning block 10 is not in use, it can be stored in the receiving hole 13. The bottom wall of the receiving hole 13 is provided with a magnet 9, and the positioning block 10 is fixed by magnetic adsorption.

[0032] In order to prevent the vertical rocker arm 3 from swinging when the calibrator is not in use, the present application installs a positioning pin 11 at the upper end of the shield 6. One end of the vertical rocker arm 3 is connected to the horizontal support shaft 2 through a sleeve. The sleeve is provided with a positioning hole. The positioning pin 11 can be inserted into the positioning hole to fix the position of the vertical rocker arm 3. One end of the positioning pin 11 is connected to the shield 6 by a pull rope to avoid loss.

[0033] In order to facilitate carrying the calibrator, the present application provides a handle 12 on the side wall of the vertical plate for the operator to hold it conveniently.

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
