Description

Technical Field

[0001] This utility model relates to the field of lighting installation, and in particular to a distance measuring device for lighting installation. Background Technology

[0002] When installing architectural lighting fixtures, Chinese aesthetics require equidistant installation. The current method of measuring distance for lighting fixture installation involves workers using a tape measure to measure each section separately, which is extremely time-consuming.

[0003] Therefore, it is necessary to design a time-saving and labor-saving distance measuring device for lighting installation. Utility Model Content

[0004] The technical problem this invention aims to solve is that the existing method of measuring distance during lamp installation involves workers measuring section by section with a tape measure, which is extremely time-consuming.

[0005] To solve the above-mentioned technical problems, the present invention provides a distance measuring device for lamp installation. The distance measuring device includes a main rod, a groove is formed inside the main rod, a slider is provided inside the groove, a slide rail is formed on one side of the main rod, a secondary rod is slidably connected inside the slide rail, one end of the secondary rod is fixedly connected to the slider, the slider is larger than the slide rail, and the surfaces of the main rod and the secondary rod are provided with measuring scales.

[0006] A plug is inserted into the bottom of the main rod, a pull block is fixedly connected to the outside of the plug, a spring is fixedly installed on the inside of the pull block, and the other end of the spring is fixedly connected to the outer wall of the main rod. Several insertion holes are opened at the bottom of the auxiliary rod.

[0007] The main rod and the auxiliary rod are each equipped with a suction cup at their top ends, and the suction cups are rotatably connected to the main rod and the auxiliary rod.

[0008] Air holes are provided at the connection between the suction cup and the main rod and the auxiliary rod. A ball is installed inside the suction cup. Both ends of the ball are fixedly connected to elastic bands. The other end of the elastic bands is fixedly connected to the bottom of the inner side of the suction cup. A top rod is inserted into the bottom of the main rod and the auxiliary rod. The other end of the top rod is inserted into the air hole. A connecting rope is fixedly connected to the outer end of the top rod. The other end of the connecting rope is fixedly connected to the main rod and the auxiliary rod.

[0009] The beneficial effects of this utility model are as follows:

[0010] Equipped with a slider, spring, and suction cup, the overall length can be adjusted by extending and retracting the secondary rod within the slide rail. The slider acts as a limit, preventing the secondary rod from completely slipping off the slide rail. The distance between the two ends of the main rod and the secondary rod can be determined by observing the measurement scale, facilitating measurement. The spring constantly pulls the pull block towards the main rod. When the overall length needs adjustment, the pull block is pulled outward. After adjustment, releasing the pull block causes the spring to automatically pull the pull block, thereby driving the insertion rod into the insertion hole for fixation. After the length is adjusted, the suction cup is attached to the surface to be measured. The suction cup facilitates the fixation of the main rod and the secondary rod. The suction cup is rotatably connected to the main rod and the secondary rod. By removing one side of the suction cup while keeping the other side attached, the next equidistant distance can be measured by rotating the removed suction cup around the attached suction cup. This facilitates equidistant measurement. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] Please see Figure 1-4 The ranging device includes a main rod 1, with a groove 2 inside the main rod 1. A slider 3 is installed inside the groove 2. A slide 4 is provided on one side of the main rod 1. A secondary rod 5 is slidably connected inside the slide 4. One end of the secondary rod 5 is fixedly connected to the slider 3. The slider 3 is larger than the slide 4. Measuring scales are provided on the surfaces of the main rod 1 and the secondary rod 5. The overall length can be adjusted by extending and retracting the secondary rod 5 within the slide 4. The slider 3 can act as a limit to prevent the secondary rod 5 from completely slipping off the slide 4. The distance between the two ends of the main rod 1 and the secondary rod 5 can be determined by observing the measuring scales, which is convenient for measurement.

[0018] A rod 6 is inserted into the bottom of the main rod 1. A pull block 7 is fixedly connected to the outside of the rod 6. A spring 8 is fixedly installed on the inside of the pull block 7. The other end of the spring 8 is fixedly connected to the outer wall of the main rod 1. Several insertion holes 9 are opened at the bottom of the auxiliary rod 5. The spring 8 always pulls the pull block 7 toward the main rod 1. When the overall length needs to be adjusted, the pull block 7 is pulled outward. After the adjustment is completed, the pull block 7 is released, and the spring 8 will automatically pull the pull block 7, thereby driving the rod 6 to be inserted into the insertion hole 9 to achieve fixation.

[0019] Suction cups 10 are installed at the top of both ends of the main rod 1 and the auxiliary rod 5. The suction cups 10 are rotatably connected to the main rod 1 and the auxiliary rod 5. After the length is adjusted, the suction cups 10 are attached to the surface to be measured. The suction cups 10 facilitate the fixation of the main rod 1 and the auxiliary rod 5. The suction cups 10 are rotatably connected to the main rod 1 and the auxiliary rod 5. One side of the suction cup 10 is removed while the other side remains attached. By rotating the removed end of the suction cup 10 around the attached end of the suction cup 10, the next equidistant distance can be measured, which facilitates equidistant measurement.

[0020] Air holes 11 are provided at the connection between the suction cup 10 and the main rod 1 and the auxiliary rod 5. A ball plug 12 is provided inside the suction cup 10. Both ends of the ball plug 12 are fixedly connected to elastic bands 13. The other end of the elastic bands 13 is fixedly connected to the bottom of the inner side of the suction cup 10. A push rod 14 is inserted into the bottom of the main rod 1 and the auxiliary rod 5. The other end of the push rod 14 is inserted into the air hole 11. A connecting rope 15 is fixedly connected to the outer end of the push rod 14. The other end of the connecting rope 15 is fixedly connected to the main rod 1 and the auxiliary rod 5. The elastic band 13 always pulls the ball plug 12 downward to block the air hole 11 and prevent air leakage during suction. When it is necessary to remove the suction cup 10, push the push rod 14 upward. At this time, the push rod 14 will push the ball plug 12 upward and release the air hole 11, so that the suction cup 10 can be de-aired, which facilitates the disassembly of the suction cup 10.
