Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, and more specifically, to a high-definition lens for surveying instruments. Background Technology

[0002] Surveying instruments and devices are designed and manufactured for data acquisition, processing, and output. They are used in the planning, design, construction, and management phases of engineering projects for various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry instruments. These instruments consist of components such as telescopes, horizontal and vertical circles, and bases. Based on the reading device, they are classified into vernier theodolites, optical theodolites, and electronic (automatic display) theodolites. Theodolites are widely used for control, topographic, and construction layout surveying. However, when using surveying instruments, it is necessary to ensure the clarity of the surveying lens. During surveying, external dust adheres to the surface of the lens, requiring cleaning after each use. This can easily scratch the lens surface, making maintenance and repair inconvenient. To address this issue, a high-definition lens for surveying instruments is proposed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-definition lens for surveying instruments. The technical problem to be solved by the present invention is: how to facilitate the inspection and maintenance of the high-definition lens of the surveying instrument.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-definition lens for a surveying instrument, comprising a surveying instrument lens housing, wherein a mounting protrusion is provided in the middle of the outer end face, a concave mounting groove is provided on the inner end face of the surveying instrument lens housing, a supporting protrusion is provided on the lower side of the inner end face of the surveying instrument lens housing, a mounting clamping block is provided on the inner end face of the concave mounting groove, and a pressing protrusion is provided on the inner end face of the mounting clamping block;

[0005] The inner end face of the mounting clamping block has a mounting groove on the lower side of the pressing protrusion, the outer end face of the pressing protrusion has a clamping band, the inner end face of the mounting groove has a surveying instrument lens, and the outer end face of the surveying instrument lens has a sealing mounting gasket.

[0006] In a preferred embodiment, the upper side of the outer end face is provided with an external mounting thread, and the inner end face of the surveyor lens housing is provided with a support limiting ring on the upper side of the pressing protrusion.

[0007] In a preferred embodiment, the outer end face of the support limiting ring is adapted to the outer end face of the surveying instrument lens housing, and two concave mounting grooves are provided, which are arranged in a mirror state on both sides of the vertical central axis of the surveying instrument lens housing in the top view direction.

[0008] In a preferred embodiment, the inner end face of the concave mounting groove is adapted to the outer end face of the mounting clamp, and the inner end face of the supporting protrusion in the top view direction and the inner end face of the sealing mounting pad in the top view direction are set in a coplanar state.

[0009] The number of mounting clamps is two, and they are arranged in a mirror image on both sides of the vertical central axis of the clamping band when viewed from above.

[0010] In a preferred embodiment, the inner end face of the mounting groove is adapted to the outer end face of the sealing mounting pad, and the clamping band is a plastic component.

[0011] In a preferred embodiment, the outer end face of the surveyor lens is adapted to the inner end face of the sealing mounting pad, and the sealing mounting pad is a rubber component.

[0012] The surveying instrument lens is convex in the main viewing direction, and the sealing mounting gasket is arranged in a ring array on the outer end face of the surveying instrument lens in the top viewing direction.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In practical use, this invention allows for convenient installation and removal of the surveying instrument lens through the corresponding arrangement of the mounting clamp, clamping protrusion, mounting groove, surveying instrument lens, and sealing mounting pad. This increases the ease of maintenance for the surveying instrument lens. Simultaneously, the sealing mounting pad ensures the lens is sealed after installation, preventing external dust from entering the surveying instrument. Furthermore, the supporting limiting ring presses against the inner end face of the mounting clamp, preventing one end of the clamp from shifting inwards and causing the surveying instrument lens to loosen. The corresponding fit between the concave mounting groove and the mounting clamp effectively increases the stability of the surveying instrument lens installation. Attached Figure Description
