Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a level measuring auxiliary device. Background Art

[0002] The level is a commonly used level that uses a micro-tilt screw to obtain a horizontal line of sight. When operating, first use a circular level to roughly level the instrument, and then use the micro-tilt screw before each reading to make the level rise and fall in the vertical plane until the level bubble is accurately centered and the line of sight is horizontal. Compared with ordinary levels, the micro-tilt precision level has a small graduation value and high sensitivity of the tube level, a large magnification and strong brightness of the telescope, and a sturdy instrument structure, especially the connection between the telescope and the tube level is firm. It is equipped with an optical micrometer and a precision leveling ruler to improve the reading accuracy. The level measuring equipment currently used all adopts a handheld measurement method, which is not conducive to the user's operation and also affects the accuracy of the measurement data. The currently used levels bring many adverse effects and inconveniences to users during use.

[0003] To solve the above problems, the existing patent (publication number: CN220205309U) is a level measurement auxiliary device. When using this device, the main body support rotating device can be set to avoid manual operation of the device and free the user's hands. At the same time, the stability and practicality of the device are improved. The user first fixes the first-level telescopic rod on the lower end outer surface of the fixed bottom, and then adjusts the position relationship between the first-level telescopic rod and the second-level telescopic rod by locking the steel ball so that the main body support rotating device can be fully supported on the ground.

[0004] However, when the level in the above-mentioned public document is not in use, its lens is exposed and easily damaged by collision. If a protective cover is added, it needs to be opened and closed manually, which is very troublesome. If you forget to close the protective cover by mistake, the lens is also at risk of being damaged by collision.

[0005] Therefore, those skilled in the art provide a level measurement auxiliary device to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0022] See also Figures 1 to 5 In an embodiment of the utility model, a level measurement auxiliary device includes a base 1, a level body 2 is arranged on the upper end of the base 1, the level body 2 is used for measuring work, the front end of the level body 2 is connected to two connecting blocks 6, the two connecting blocks 6 are rotatably connected with a rotating column 7, the rotating column 7 can rotate on the connecting block 6, the rotating column 7 is connected to the baffle 9 by two connecting rods 8, the baffle 9 is consistent in size with the lens on the level body 2, and the baffle 9 is used to block the lens.

[0023] The internal rotation of the level body 2 is connected to a driving wheel 14, and the rotating column 7 is fixedly connected to a driven wheel 16. The driving wheel 14 and the driven wheel 16 are connected by a chain 15. When the driving wheel 14 rotates, the driven wheel 16 is driven to rotate synchronously through the chain 15, and the chain 15 runs through the level body 2.

[0024] A spring column 11 is fixedly connected inside the level body 2, and the lower end of the spring column 11 is fixedly connected to the push rod 10. The spring column 11 is used to restore the push rod 10 that is not subject to external force to its original position. The push rod 10 passes through the lower end of the level body 2. A plurality of tooth grooves 12 are provided on the push rod 10. A gear 13 is fixedly connected to the driving wheel 14. When the push rod 10 moves, the tooth groove 12 will push the gear 13 to rotate.

[0025] A support rod 17 is rotatably connected to the base 1, and a movable rod 18 is slidably connected to the support rod 17. The support rod 17 and the movable rod 18 are used to support the level body 2. A positioning cone 19 is fixedly connected to the lower end of the movable rod 18. The positioning cone 19 can be inserted into the ground for fixation when the level is in use, thereby ensuring its stability during measurement.

[0026] A clamp ring 20 is sleeved on the support rod 17 and can be deformed when squeezed. A spiral rod 21 is spirally connected to the clamp ring 20. The tightness of the clamp ring 20 can be adjusted by rotating the spiral rod 21, thereby fixing the movable rod 18 based on the support rod 17.

[0027] The working principle of the utility model is as follows: when the device needs to be used for measurement, the support rod 17 is first rotated based on the base 1, and the support rod 17 rotates to drive the movable rod 18 and the positioning cone 19 to rotate synchronously. When the three rotate to the appropriate position, they stop and are placed at the construction point. At this time, the stable placement of the device is completed. If the construction ground is uneven, the spiral rod 21 can be rotated at this time to adjust the clamping ring 20 to a relaxed state, and then the movable rod 18 is moved along the support rod 17, so that the movable rod 18 drives the positioning cone 19 to move and contact and support the uneven ground, ensuring that the device can still be used on the uneven ground It can remain stable, and then the level body 2 is inserted into the base 1. Limited by the base 1, the push rod 10 will move toward the inside of the level body 2. When the push rod 10 moves, on the one hand, it will squeeze the spring column 11, and on the other hand, it will push the gear 13 to rotate through the tooth groove 12. When the gear 13 rotates, it drives the driving wheel 14 to rotate. Under the action of the chain 15, the driven wheel 16 rotates synchronously, so that the rotating column 7 rotates on the connecting block 6, and finally the baffle 9 is turned over through the connecting rod 8, so that the lens on the level body 2 is opened, and the staff does not need to open it manually, saving time and effort.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
