Description

Technical Field

[0001] This utility model relates to the field of rangefinder technology, specifically a handheld laser rangefinder. Background Technology

[0002] Handheld laser rangefinders are widely used tools in surveying, construction, exploration and other fields. They are designed to provide portable and fast distance measurement solutions.

[0003] Handheld laser rangefinders are typically small and lightweight, making them easy for users to carry and use for quick measurements in various environments. However, they suffer from drawbacks such as being prone to dropping and inconvenient to store. In practice, due to the need to frequently take the rangefinder out and put it back, traditional handheld designs often lack sufficient protective measures, making the rangefinder susceptible to damage from accidental drops. Furthermore, when not in use, users usually need to put the rangefinder in their pockets or bags, which can not only damage it due to impacts but also affect work efficiency due to the inconvenience of taking it out and putting it back. Therefore, handheld laser rangefinders were proposed to solve the aforementioned problems. Utility Model Content

Fixing components are provided on both sides between the lower housing 1 and the upper housing 2. A clamping component is provided on the front side of the lower housing 2.

[0029] Example 1: The fixing assembly includes an adjusting plate 7, two connecting blocks and a connector 10. A sliding groove 6 is provided on the side of the lower housing 1. The adjusting plate 7 is in the shape of a boss and is slidably connected to the sliding groove 6. The two connecting blocks are the first connecting block 8 and the second connecting block 9, which are respectively bolted to the adjusting plate 7 and the upper housing 2 on the same side. The connector 10 is installed between the two connecting blocks.

[0030] In this embodiment, the upper box 2 is welded with plugs near the four corners at the bottom, and the lower box 1 is provided with plug slots at the top corresponding to the four plugs, and plugs into the four plugs respectively, thereby initially fixing the upper box 2 and the lower box 1.

[0031] In this embodiment, guide grooves 4 are provided on both sides of the rangefinder body 3, and guide protrusions 5 are provided on the inner walls of the lower box 1 and the upper box 2 at the corresponding positions of the guide grooves 4 and are inserted into the guide grooves 4 to install the rangefinder body 3 inside the lower box 1 and the upper box 2.

[0032] In this embodiment, both connecting blocks are H-shaped in cross-section, with a cylindrical part in the middle. The connecting member 10 consists of two rings 1001 and two connecting plates 1002. The two rings 1001 are rotatably connected to the cylinder in the middle of the two connecting blocks, so that the upper box 2 can be rotated when the upper box 2 is opened.

[0033] In this embodiment, the first connecting block 8 is bolted to the upper middle part of the outer side of the adjusting plate 7. The lower middle part of the adjusting plate 7 is provided with a fixing through hole 11. The side of the slide 6 is provided with an adjusting groove 12 near the bottom. When the adjusting plate 7 slides to the bottom limit in the slide 6, the fixing through hole 11 and the adjusting groove 12 are directly opposite each other.

[0034] In this embodiment, one end of the spring assembly 14 is fixedly installed on the end face of the adjustment groove 12, and the other end of the spring assembly 14 is bolted to the pressing plate 13. The spring assembly 14 is composed of multiple springs and is circumferentially distributed between the adjustment groove 12 and the pressing plate 13. The diameter of the pressing plate 13 is smaller than the diameter of the fixing through hole 11, and it is inserted into the fixing through hole 11.
