Description

Technical Field

[0001] The invention relates to the technical field of decoration and renovation, and in particular to a sprinkler head centering positioning tool for decoration. Background Art

[0002] In the process of decoration and renovation, for the sake of beautiful visual effects and convenient construction and maintenance, the ceiling is mostly constructed with block surface layers (such as high crystal panels, aluminum gusset plates) and other materials instead of integral surface layers. In addition, the professional end points are generally installed in the center, such as the sprinkler heads installed on the block ceiling. Existing centering positioning methods include directly laying out lines to determine the intersection, or directly installing the sprinkler head after installing the main and secondary keels. However, no matter laying out the lines or installing the main and secondary keels first, the sprinkler head cannot be accurately placed in the center of a ceiling panel. This is because when determining the intersection by directly laying out the lines, people need to fix a line in the middle of both ends of the aisle, and at the same time, a line perpendicular to the above line is set at the horizontal position of the aisle. The middle point is determined by the intersection of the two lines. However, when fixing the above two lines, it is also necessary to control the fixing point of the line to be in the middle of the aisle. In case the middle point is wrong, the exact center position of the ceiling panel cannot be determined. In the installation operation of the main and secondary keels, the installation of the main and secondary keels is affected by the size of the building and the position of the aisle, and it cannot be guaranteed that the main and secondary keels are directly in the middle of the aisle. Therefore, the center position of the ceiling panel cannot be accurately located.

[0003] Therefore, it is necessary to provide a decoration sprinkler head centering positioning tool to solve the above technical problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a sprinkler head centering positioning tool for decoration.

When the device is in use, first rotate and unfold the first rotating frame and the second rotating frame to a mutually horizontal state on the aisle where the sprinkler head is installed, then make one end of the extrusion block contact one end of the first rotating frame and the second rotating frame, then move the middle end position of the first rack and the second rack connected to the extrusion block to the middle plane of the fixed column through the centering device, then rotate the device as a whole to the position where the middle position needs to be measured, then fix the aisle through the operation of the centering device, and then measure the center position of the ceiling board through the operation of the centering drawing device.

[0006] Preferably, the top of the top plate is provided with mounting grooves in a circular array, and a first anti-skid rubber pad is installed in the middle of the mounting groove. When the top plate is placed on the top of the corridor ceiling, the first anti-skid rubber pad is in contact with the ceiling to fix the entire device, thereby preventing the top plate from sliding on the corridor ceiling due to human force.

[0007] Preferably, the centering device comprises a first rack, a second rack, a rotating rod, a first gear, a second gear and a first hand wheel, the middle parts of the first rotating frame and the second rotating frame are provided with positioning grooves, the first rack and the second rack are slidably installed in the two positioning grooves, the first rack and the second rack are arranged in two sections, the middle ends of the first rack and the second rack are installed by damping rotation, one end of the first rack and the second rack are fixedly connected to the extrusion block, the rotating rod is rotatably installed between the top plate and the bottom plate through the bearing, the first gear and the second gear are fixedly installed on the outer side of the rotating rod corresponding to the position of the first rack and the second rack, the first rack is meshed with the first gear, the second rack is meshed with the second gear, and the bottom of the rotating rod is fixedly installed with a first hand wheel for rotating the rotating rod. By rotating the first hand wheel, the movement of the first rack and the second rack is driven, so that the two extrusion blocks can squeeze the two ends of the aisle, and the central position of the ceiling of the aisle can be determined.

[0008] Preferably, the two extrusion blocks are fixedly mounted with second anti-skid rubber pads at one end away from the first rack and the second rack respectively, so as to prevent the whole device from sliding on the wall of the aisle when the extrusion blocks squeeze the two ends of the aisle.

[0009] Preferably, an anti-slip plate is fixedly mounted on one end of the two extrusion blocks away from the second anti-slip rubber pad to prevent the first rack and the second rack from slipping out of the positioning groove when the device is stored.

After the centering position is determined, the lifting plate can be driven to rotate by rotating the second hand wheel, so that the first drawing marker draws a circle on the ceiling, and the drawing of the center position is realized.

[0012] Preferably, a second fixed fork is fixedly installed in the middle of the upper surface of the lifting plate, and a second drawing marker is slidably placed inside the second fixed fork. During the rotation of the lifting plate, a dot can also be drawn on the ceiling by the second drawing marker to achieve drawing at the center point.

[0013] Compared with the related art, the present invention has the following beneficial effects:

[0014] When the present invention is used, the first rotating frame and the second rotating frame are first rotated and unfolded to a mutually horizontal state on the aisle where the sprinkler head is installed, and then the middle end positions of the first rack and the second rack are moved to the middle plane of the fixed column through the operation of the centering device, and then the device as a whole can be rotated to a position perpendicular to the aisle, and the top plate is placed against the surface of the ceiling, and then the two extrusion blocks are squeezed against the aisle through the storage operation of the centering device to fix the device. At this time, the fixed column will be in the middle of the ceiling, and the device is determined to be in the middle of the ceiling of the aisle;

[0015] The lifting plate is driven to rotate by the operation of the centering drawing device, so that the first drawing marker draws a circle on the ceiling to achieve drawing at the center position. At the same time, a dot is drawn on the ceiling by the second drawing marker to achieve drawing at the center point.

[0016] When measuring the middle of the next aisle ceiling, the squeezing of the aisle by the squeezing block is cancelled by the operation of the centering device, and the device can be directly moved to the next aisle ceiling position to achieve measurement of the middle of the ceiling, making it convenient for people to reuse the device.
