Abstract
Description
Technical Field
[0001] The utility model relates to the field of measurement, in particular to a nighttime level measurement scale lighting device. Background Art
[0002] In leveling, when there is a bridge on the leveling route and the heavy traffic during the day makes it impossible to measure the bridge vibration normally, it is often necessary to measure at night when there are fewer vehicles. There are currently two common practices. One is to add two staff members, each holding a flashlight, to illuminate the two leveling rods respectively so that the observation can be carried out normally. This is the most commonly used method at present, but when the measurement team is in the field and cannot send additional personnel, the work cannot be carried out normally. The second is to clamp the lighting strip on the leveling rod, but because the light strip is too long to be carried, and the failure rate is high, and the required mobile power supply is difficult to fix on the rod, it has not been popularized.
[0003] In order to solve the above problems, the utility model proposes a nighttime leveling measuring scale lighting device to achieve the purpose of facilitating nighttime measurement. Utility Model Content
[0004] The purpose of the utility model can be achieved through the following technical solutions:
[0005] A nighttime leveling scale lighting device comprises a magnetic bracket and a connecting bracket matched therewith, wherein the magnetic bracket comprises a connecting block 1 and a connecting block 2, two parallel spring rods are connected between the connecting block 1 and the connecting block 2, and the front parts of the connecting block 1 and the connecting block 2 are both integrally connected with a limit rod away from the side.
[0006] The connecting bracket includes a magnetic frame, the bottom of the magnetic frame is connected to a beam shaper, and both sides of the rear of the magnetic frame are provided with magnetic grooves adapted to the limit rod;
[0007] Screw holes are opened on both sides of the front of the magnetic frame, and a connecting fixing bracket is provided at the front of the magnetic frame. Fixing bolts matching the screw holes are threadedly connected through both sides of the front of the fixing bracket, and a columnar light source is provided between the rear of the fixing bracket and the front of the magnetic frame.
[0008] As a further solution of the utility model, an arc groove is provided at the center of the rear of the fixing bracket and at the center of the front of the magnetic frame, and the columnar light source is located inside the two arc grooves.
[0009] As a further solution of the utility model, the limit rod is arranged in an L shape, and the transverse section of the limit rod is clamped and adsorbed inside the magnetic attraction groove.
[0010] Beneficial effects of the utility model:
[0011] The utility model cooperates with the connecting bracket by arranging a magnetic bracket and connects the connecting block one with the connecting block two by arranging a spring rod, so that the two limit rods can be easily separated and quickly assembled to the two sides of the leveling ruler, and then the magnetic groove and the limit rod are adsorbed and fixed, so that the magnetic bracket and the connecting bracket can be quickly assembled, and then the fixed bracket and the columnar light source are fixed by fixing bolts to realize the rapid fixation of the columnar light source, so that it is convenient and quick to put into use for night measurement lighting, and the overall structure is simple, easy to carry, and easy to use. At the same time, because it is suitable for long strip measuring tools, it can be used not only for leveling rulers, but also for optical leveling rulers and electronic leveling rulers, and has a wide range of applications.
