Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, specifically an improved detection instrument. Background Technology

[0002] In recent years, with the rapid development of my country's social economy and the continuous acceleration of urbanization, the development of highway and bridge construction has been remarkable, making a significant contribution to the rapid development of the national economy. After the completion of highway and bridge construction, rigorous testing is required. Even the slightest substandard quality in a highway or bridge can pose a danger to vehicles and pedestrians. Levelness testing of highways and bridges is a crucial aspect of this process. However, traditional highway levelness testing devices are all mechanical measuring tools, requiring manual observation of the degree readings after measurement. If construction workers accidentally touch the leveling instrument while taking readings, it can cause angular deviations, necessitating recalibration. Furthermore, existing leveling instruments can only measure a specific area of ​​the road surface and cannot be moved to measure horizontally, limiting the measurement area and reducing their practicality. Utility Model Content

[0003] The purpose of this invention is to provide an improved detector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved detector, comprising a housing, a first movable plate provided in a groove of the housing, a first connecting shaft symmetrically and movably provided on the first movable plate, a roller movably connected to the first connecting shaft, the roller slidingly connected to the groove of the housing, an internal gear fixedly connected to the first movable plate, a first gear symmetrically meshing within the internal gear, a second connecting shaft fixedly connected to each of the first gears, a first connecting plate fixedly connected to each of the second connecting shafts, a level detector fixedly connected to the upper end of the first connecting plate, a third connecting shaft fixedly connected to the lower end of the first connecting plate, the third connecting shaft passing through the first movable plate, a first telescopic shaft fixedly connected to the lower end of the third connecting shaft, a first strip chain fixedly connected to the lower end of the first telescopic shaft, second gears meshing at both ends of the first strip chain, a fourth connecting shaft provided on the second gear, a second connecting plate fixedly connected to both ends of the fourth connecting shaft, a second telescopic shaft fixedly connected to the second connecting plate, a second strip chain meshing with the second gear, and a sleeve fixedly connected to the second strip chain.

[0005] Preferably, a first connecting sleeve is fixedly connected to the second telescopic shaft.

[0006] Preferably, a fifth connecting shaft is fixedly connected to the first connecting sleeve, a sixth connecting shaft is fixedly connected between the fifth connecting shafts, a second movable plate is fixedly connected to the sixth connecting shaft, and a locking pin is fixedly connected to one end of the second movable plate.

[0007] Preferably, one end of the first telescopic shaft is provided with a slot.

[0008] Preferably, the sleeve is fixedly connected to a support frame arranged in a ring around the center.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The level measuring instrument is fixed on the first connecting plate by a buckle on the first connecting plate. The symmetrically arranged second connecting shaft is fixed on the first gear. When the first gear meshes with the internal gear, the level measuring instrument remains on a horizontal plane regardless of its rotation. When the first movable plate slides left and right, the rollers on the first movable plate slide in the grooves at both ends of the housing, so that the level measuring instrument also moves on the same horizontal plane when moving left and right. Since the first and second chains are equipped with racks that match the second gear, pulling the first telescopic shaft upward causes the first chain fixedly connected to it to mesh with the first gear inside the second telescopic shaft. The first gear simultaneously meshes with the second chains at both ends inside the sleeve, allowing the first and second telescopic shafts to be adjusted upward in height. After the height adjustment is completed, the locking pin can be engaged in the slot, firmly fixing the first and second telescopic shafts. This avoids the situation where the level measuring instrument is accidentally touched by the construction worker during reading, resulting in an angle deviation and requiring recalibration. Furthermore, the equipment can be moved and measured in a horizontal area, increasing the measurement area and improving the practicality of the equipment. Attached Figure Description

The second gear 13 is provided with a fourth connecting shaft 14, and the two ends of the fourth connecting shaft 14 are fixedly connected to a second connecting plate 15. The second connecting plate 15 is fixedly connected to a second telescopic shaft 16. The second gear 13 is engaged with a second strip chain 17, and the second strip chain 17 is fixedly connected to a sleeve 18.

[0017] Furthermore, a first connecting sleeve 19 is fixedly connected to the second telescopic shaft 16. The first connecting sleeve 19 is used to connect the fifth connecting shaft 20, the sixth connecting shaft 21, the second movable plate 22, and the locking pin 23.
