Description

Technical Field

[0001] The utility model relates to the field of level instruments, in particular to a level auxiliary ruler-finding device. Background Technique

[0002] A level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the level measurement principle. When an ordinary optical level is used for outdoor night operations, it is difficult to find and aim at the leveling staff due to insufficient light. Usually, the instrument needs to be adjusted many times, resulting in low work efficiency.

[0003] According to a patent document with the publication number CN220104096U, a night auxiliary ruler-finding device for a level is disclosed. It includes a level body and a leveling staff. Both the front and rear ends of the shell of the level body are fixedly connected with two limiting strips arranged at intervals front and back. A plug-in block with an n-shaped cross-section is clamped on the shell of the level body. The left and right ends of the plug-in block are respectively located between the corresponding two limiting strips. A rectangular installation groove is opened at the upper end of the plug-in block, and a fixing block with a shape matching that of the installation groove is placed in the installation groove. When this technical solution is used, the infrared emitter can emit longitudinal infrared laser. Then, when measuring in a place with insufficient light at night, the infrared emitter is turned on, and the vertically inserted leveling staff can be quickly found by using the longitudinal infrared laser for measurement work. For the above technical solution, although the scheme realizes the quick search for the leveling staff, the infrared emitter body cannot be shielded and protected after use, and collision is likely to cause damage to the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a leveling instrument auxiliary ruler-finding device, including a device body. The device body includes a fixed seat 1, a support seat 2 is movably installed on the top of the fixed seat 1, an adjustment knob 3 is installed between the support seat 2 and the fixed seat 1, a limiting component 4 is movably installed on the fixed seat 1, a rotating seat 5 is rotatably installed on the support seat 2, a mounting seat 6 is fixed on the rotating seat 5, a fixed block 9 is fixed on the top of the mounting seat 6, a connecting rod 11 is movably installed on the fixed block 9, one end of the connecting rod 11 is fixed with a movable block 10, a movable cylinder 12 is fixedly installed between the movable block 10 and the fixed block 9, an objective lens 7 is fixedly installed at one end of the mounting seat 6, an eyepiece 8 is fixedly installed at the other end of the mounting seat 6. Receiving grooves are opened on one side of the fixed block 9 and the movable block 10, and both ends of the movable cylinder 12 are movably installed inside the receiving grooves for receiving, and the two ends of the movable cylinder 12 are sealed after receiving.

[0024] In this embodiment, a sliding groove 13 is opened on the top of the mounting seat 6, a slider 14 is movably installed inside the sliding groove 13, the slider 14 is installed inside the sliding groove 13 through a support mechanism 15, a rotating column 16 is rotatably installed on the slider 14, one end of the rotating column 16 is fixed on the movable cylinder 12, a lighting lamp 17 and an infrared emitter are respectively fixedly installed at both ends of the movable cylinder 12. The limiting component 4 includes a mounting groove 18, a limiting plate 19 is movably installed inside the mounting groove 18, a fixing hole 20 is opened on the limiting plate 19, and the support mechanism 15 is a support spring. The support spring enables the slider 14 to move inside the sliding groove 13, and when the movable cylinder 12 does not need to move, one end of the movable cylinder 12 is pressed against the fixed block 9 through the support mechanism 15 for limiting.

[0025] In this embodiment, a limiting groove 21 is opened on the inner wall of the mounting groove 18, a reset mechanism 22 is fixedly installed inside the limiting groove 21, one end of the reset mechanism 22 is fixed with a limiting block 23, one end of the limiting block 23 is fixed on the limiting plate 19, an opening is opened on the fixed seat 1, a threaded pipe 24 is fixed at the top of the opening, a threaded column 25 is rotatably installed inside the threaded pipe 24, a movable column 26 is movably installed inside the threaded column 25, one end of the movable column 26 is matched with the limiting plate 19, a groove 27 is opened on the side of the movable column 26, a convex block 28 is movably installed inside the groove 27, and the convex block 28 is movably installed inside the groove 27. The reset mechanism 22 is a reset spring, and the reset spring pushes the limiting plate 19 to return later. When the limiting plate 19 loses the support of the movable column 26, the limiting plate 19 shrinks into the mounting groove 18 for receiving.

[0026] The device provides the required electrical energy for the electrical appliances inside the device through the internal storage battery. When using this device, first place the fixing base 1 on the bracket and the bracket seat. After the fixing base 1 is placed on the bracket seat, press the movable column 26 with a tool. The movable column 26 moves downward to squeeze the limiting plate 19. The limiting plate 19 moves toward the side of the fixing base 1 under the squeeze. After the limiting plate 19 moves out, it limits the fixing base 1. When the fixing base 1 needs to be quickly disassembled, after moving the movable column 26 upward, one end of the limiting plate 19 loses the supporting force, and the reset mechanism 22 pushes the limiting plate 19 to contract and be stored inside the installation groove 18. After the limiting plate 19 moves out and continues to move, the position of the fixing hole 20 is exposed. The fixing base 1 can be fixed at the use position through the fixing hole 20 with bolts. When the fixing base 1 needs to be fixedly installed for a long time, rotate the threaded column 25. The threaded column 25 rotates and pushes the convex block 28 through one end of the groove 27 to make the movable column 26 move downward. The movable column 26 is limited by the cooperation of the convex block 28 and the groove 27, and the fixing base 1 can be fixedly installed for a long time. When this device needs to be used, the movable block 10 rotates on the fixing block 9 through the connecting rod 11. The rotation opens one end of the movable cylinder 12. After one end of the movable cylinder 12 is opened, it is used for lighting at night through the lighting lamp 17. When the working ruler needs to be found, drive one end of the movable cylinder 12 to separate from the fixing block 9 by the slider 14. After separation, the movable cylinder 12 rotates through the rotating column 16 to expose one end of the infrared emitter. Turn on the infrared emitter, and the vertical leveling staff inserted vertically can be quickly found by using the longitudinal infrared laser for measurement work, without the need for manual lighting to search.
