Description

Technical Field

[0001] This utility model belongs to the field of rangefinder technology, specifically relating to a rangefinder for building construction. Background Technology

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target by modulating a laser with a specific parameter. A pulsed laser rangefinder emits a single or a series of short pulsed laser beams towards the target. A photoelectric element receives the reflected laser beam, and a timer measures the time from emission to reception to calculate the distance from the rangefinder to the target.

[0003] However, existing laser rangefinders often lack protective structures and are easily damaged after being dropped. Furthermore, the laser lights on existing rangefinders often lack dustproof features, which can easily cause dust to accumulate on the surface of the laser lights, resulting in inconvenience during use. Therefore, there is an urgent need for a rangefinder for building construction to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a rangefinder for building construction, so as to solve the problem that existing laser rangefinders often do not have a protective structure and are easily damaged after being dropped, and the laser lights on existing rangefinders often do not have a dustproof function, which easily causes dust to accumulate on the surface of the laser light.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rangefinder for building construction, comprising a silicone sleeve, rubber buffer pads, a dustproof structure, and a laser rangefinder body. Two rubber buffer pads are fixedly connected to the inner walls of both the front and rear ends of the silicone sleeve. The dustproof structure includes a dustproof plate and a fixed base. The dustproof plate is rotatably connected to the silicone sleeve. A rotating shaft is rotatably connected to the rear side of the dustproof plate. A pull ring is fixedly connected to the rear side of the rotating shaft. A buckle is slidably connected to the fixed base. A connecting rod is fixedly connected to the rear side of the buckle. A sliding plate is fixedly connected to the rear side of the connecting rod. The laser rangefinder body is installed inside the silicone sleeve.

[0006] Preferably, protective blocks are fixedly connected to all four corners of the silicone sleeve, and laser holes are provided at the rear end of the protective blocks.

[0007] Preferably, the silicone sleeve has grooves at all four corners, and rubber buffer pads are fixedly connected to the inner walls of the grooves.

[0008] Preferably, a rubber ring is fixedly connected to the rear side of the dustproof plate, and the rubber ring is engaged with the laser hole.

[0009] Preferably, the upper and lower sides of the buckle are fixedly connected to sliders, and the sliders are slidably connected to the inner wall of the fixing base.

[0010] Preferably, the fixing seat is provided with two springs, one end of the spring abutting against the inner wall of the fixing seat, and the other end of the spring abutting against the inner wall of the buckle.

[0011] Preferably, the right end of the dustproof plate and the left end of the buckle are both provided with slopes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This laser rangefinder for building construction is equipped with a silicone sleeve and a rubber buffer pad. The elasticity of the silicone sleeve allows the laser rangefinder body to be encased within it, providing protection. The protective blocks reinforce the thickness of the four corners of the silicone sleeve, thus offering better protection. The rubber buffer pad absorbs the impact at the four corners of the silicone sleeve. When the device is dropped, the silicone sleeve and rubber buffer pad cushion the impact on the laser rangefinder body, preventing damage and protecting the surface of the laser rangefinder body from bumps and knocks, making it safer to use.

[0014] 2. This type of laser rangefinder for building construction is equipped with a dustproof structure. When the laser rangefinder body is needed, sliding the sliding plate causes the latch to move to the right, compressing the spring and causing the latch to retract into the fixed seat, thus releasing the dustproof plate. Pulling the pull ring causes the dustproof plate to rotate, removing the dustproof plate from the laser aperture, allowing the laser rangefinder body to function normally. The position of the dustproof plate is fixed by the damping of the hinge. When the laser rangefinder body is not in use, pressing the dustproof plate causes it to press against the latch. When the dustproof plate is closed, the spring force pushes the latch to lock the dustproof plate in place, and the rubber ring engages with the laser aperture, sealing the aperture to prevent dust from entering. The dustproof structure seals the laser aperture, preventing the laser lamp of the laser rangefinder body from being exposed to the outside and causing dust to accumulate on its surface, thus protecting the laser lamp and facilitating its use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a rangefinder for building construction, comprising a silicone sleeve 1, rubber buffer pads 2, a dustproof structure 3, and a laser rangefinder body 4. Two rubber buffer pads 2 are fixedly connected to the inner walls of both the front and rear ends of the silicone sleeve 1. The dustproof structure 3 includes a dustproof plate 32 and a fixing seat 36. The dustproof plate 32 is rotatably connected to the silicone sleeve 1. The rear side of the dustproof plate 32 is rotatably connected to a rotating shaft 35. The rear side of the rotating shaft 35 is fixedly connected to a pull ring 34. The fixing seat 36 is slidably connected to a buckle 37. The rear side of the buckle 37 is fixedly connected to a connecting rod 311. The rear side of the connecting rod 311 is fixedly connected to a sliding plate 310. The laser rangefinder body 4 is installed inside the silicone sleeve 1.

[0023] Furthermore, protective blocks 11 are fixedly connected to all four corners of the silicone sleeve 1. Laser holes 12 are provided at the rear end of the protective blocks 11. The thickness of the four corners of the silicone sleeve 1 can be increased by the protective blocks 11, thereby providing better protection.

[0024] Furthermore, grooves are provided at all four corners of the silicone sleeve 1, and rubber buffer pads 2 are fixedly connected to the inner walls of the grooves of the silicone sleeve 1. The rubber buffer pads 2 can absorb the cushioning effect on the four corners of the silicone sleeve 1.

[0025] Furthermore, a rubber ring 33 is fixedly connected to the rear side of the dustproof plate 32. The rubber ring 33 is engaged with the laser hole 12, and the laser hole 12 can be sealed by the rubber ring 33 to prevent dust from entering.

[0026] Furthermore, sliders 38 are fixedly connected to both the upper and lower sides of the buckle 37. The sliders 38 are slidably connected to the inner wall of the fixing base 36, making the movement of the buckle 37 more stable.

[0027] Furthermore, two springs 39 are provided inside the fixing base 36. One end of the spring 39 abuts against the inner wall of the fixing base 36, and the other end of the spring 39 abuts against the inner wall of the buckle 37. The elastic force of the spring 39 pushes the buckle 37 to lock the position of the dustproof plate 32.

[0028] Furthermore, the right end of the dustproof plate 32 and the left end of the buckle 37 are both provided with ramps.

[0029] Working principle:

[0030] In use, the elasticity of the silicone sleeve 1 encases the laser rangefinder body 4, providing protection. The protective blocks 11 reinforce the thickness of the four corners of the silicone sleeve 1, further enhancing protection. The rubber buffer pads 2 absorb impact from the corners of the silicone sleeve 1. When the device is dropped, the silicone sleeve 1 and rubber buffer pads 2 cushion the impact on the laser rangefinder body 4, preventing damage and protecting its surface from impacts, thus enhancing safety. When the laser rangefinder body 4 needs to be used, sliding the sliding plate 310 moves the latch 37 to the right, causing the spring 39 to contract under pressure, retracting the latch 37 into the fixing seat 36, preventing the latch 37 from... Then, snap the dust cover 32 in place and pull the pull ring 34 to make the pull ring 34 rotate the dust cover 32. The dust cover 32 will no longer block the laser hole 12, and the laser rangefinder body 4 can be used normally. The position of the dust cover 32 is fixed by the damping of the hinge 31. When the laser rangefinder body 4 is not in use, press the dust cover 32 to squeeze the buckle 37. When the dust cover 32 is closed, the elastic force of the spring 39 pushes the buckle 37 to lock the position of the dust cover 32. The rubber ring 33 is inserted into the laser hole 12. The rubber ring 33 can seal the laser hole 12 to prevent dust from entering. The dustproof structure 3 can seal the laser hole 12 to prevent the laser lamp of the laser rangefinder body 4 from being exposed to the outside, causing dust to fall on the surface of the laser lamp. This protects the laser lamp and facilitates its use.
