Description

Technical Field

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

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target using a modulated laser with specific parameters. A pulsed laser rangefinder emits one or more short pulses of laser light 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. Laser rangefinders are widely used in topographic surveying, battlefield surveying, and ranging targets from tanks, aircraft, ships, and artillery. They are also used to measure the altitude of clouds, aircraft, missiles, and artificial satellites. It is a crucial technological tool for improving the accuracy of tanks, aircraft, ships, and artillery. Due to the continuously decreasing price of laser rangefinders, they are increasingly being used in industry, finding wide applications in industrial measurement and control, mining, ports, and other fields.

[0003] However, when using laser rangefinders for land surveying, existing staff need to move the laser rangefinders to the outdoor survey area. The laser rangefinder consists of the main body and a tripod, and the tripod is quite large. Staff need to prepare a lot of space to carry the laser rangefinder, which is inconvenient. Therefore, it does not meet the current needs. In response, we proposed a portable laser rangefinder for land surveying. Utility Model Content

[0004] The purpose of this utility model is to provide a portable laser rangefinder for land surveying, in order to solve the problem mentioned in the background art that when workers use laser rangefinders for land surveying, they need to move the laser rangefinder to the outdoor area to be surveyed. The laser rangefinder consists of a laser rangefinder body and a tripod, and the tripod is relatively large, so workers need to prepare a lot of space to carry the laser rangefinder, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable laser rangefinder for land surveying, comprising a laser rangefinder body:

[0006] The mounting plate is fixedly installed on both sides of the upper and lower end faces of the laser rangefinder body. Four flexible limiting rings are fixedly installed on the outside of the mounting plate. A mounting base plate is fixedly installed at the lower end of the laser rangefinder body. The lower end of the mounting base plate has three mounting slots arranged in a ring.

[0007] Telescopic support legs are installed at the lower end of the mounting base plate, with the upper end of the telescopic support legs extending into the interior of the mounting base plate. Side plate rubber filling layers are fixedly installed on both sides of the laser rangefinder body. A safety cover is installed on the rear end face of the laser rangefinder body through a slot. A convenient handle is fixedly installed on the upper end of the laser rangefinder body.

[0008] Preferably, the lower end of the telescopic support leg is equipped with a support foot, and the support foot is connected to the telescopic support leg by a thread.

[0009] Preferably, an elastic rope is installed at the lower end of the mounting base plate, and the elastic rope is fixedly connected to the mounting base plate.

[0010] Preferably, an anti-reverse pull ring is installed at the lower end of the elastic rope, and the anti-reverse pull ring is fixedly connected to the elastic rope.

[0011] Preferably, rubber baffles are installed at both the front and rear ends of the mounting plate, and the rubber baffles are bonded to the mounting plate.

[0012] Preferably, storage boxes are installed on both sides of the upper surface of the laser rangefinder body.

[0013] Preferably, a sealing cover is installed at the upper end of the storage box, and the sealing cover is connected to the storage box through a slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes the flexibility of a flexible limiting ring to cover the telescopic support leg, allowing it to be stored outside the laser rangefinder body when the device is carried. This makes all components of the device more compact, reducing the carrying space and making the device easier to carry. Simultaneously, when the telescopic support leg is stored outside the laser rangefinder body, it forms a protective frame, enhancing the device's impact resistance and making it safer to carry. Installing the telescopic support leg minimizes the space occupied by the leg while ensuring support for the laser rangefinder body, making the device more compact and reducing its carrying space, thus making it more user-friendly.

[0016] 2. This utility model improves the impact resistance of the device by installing a rubber filling layer on the side plate, protecting the side of the laser rangefinder body. The installation of anti-tipping pull rings and elastic ropes allows the device to be used in windy weather. The anti-tipping pull rings can be attached to clothing by the ropes, so that when the wind blows the device over, the elastic ropes provide traction, preventing the laser rangefinder body from contacting the ground and effectively protecting the laser rangefinder body from damage.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-4 The present invention provides an embodiment of a portable laser rangefinder for land surveying, comprising a laser rangefinder body 1:

[0024] Mounting plate 3 is fixedly installed on both sides of the upper and lower end faces of the laser rangefinder body 1. Four flexible limiting rings 4 are fixedly installed on the outside of mounting plate 3. The flexible limiting rings 4 can cover the telescopic support legs 7 with their flexibility, so that the telescopic support legs 7 can be stored outside the laser rangefinder body 1 when the device is carried. This makes all the components of the device gathered outside the laser rangefinder body 1, making the device more compact and reducing the carrying space of the device, thus making the device easier to carry. At the same time, when the telescopic support legs 7 are stored outside the laser rangefinder body 1, they can form a protective frame for the laser rangefinder body 1, enhancing the impact resistance of the device and making the device safer to carry. A mounting base plate 6 is fixedly installed at the lower end of the laser rangefinder body 1. The lower end of the mounting base plate 6 has three mounting slots 15 arranged in a ring.

[0025] Telescopic support legs 7 are installed at the lower end of the mounting base plate 6. Installing telescopic support legs 7 can minimize the size of the device while ensuring support for the main body 1 of the laser rangefinder. The space occupied by telescopic support legs 7 makes the device more compact and reduces the space occupied when carrying the device, making the device more user-friendly. The upper end of the telescopic support legs 7 extends into the interior of the mounting base plate 6. Side plate rubber filling layers 2 are fixedly installed on both sides of the main body 1 of the laser rangefinder. Installing side plate rubber filling layers 2 can improve the impact resistance of the device and protect the sides of the main body 1 of the laser rangefinder. A safety cover 14 is installed on the rear end face of the main body 1 of the laser rangefinder through a slot. A convenient handle 13 is fixedly installed on the upper end of the main body 1 of the laser rangefinder.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The lower end of the telescopic support leg 7 is equipped with a support foot 10, which is connected to the telescopic support leg 7 by a thread. The lower end of the mounting base plate 6 is equipped with an elastic rope 8, which is fixedly connected to the mounting base plate 6. The lower end of the elastic rope 8 is equipped with an anti-tipping pull ring 9. The installation of the anti-tipping pull ring 9 and the elastic rope 8 allows the operator to attach the anti-tipping pull ring 9 to clothing via a rope when the device is used in windy weather. When the wind blows the device over, the elastic rope 8 provides traction to prevent the laser rangefinder body 1 from contacting the ground, effectively protecting the laser rangefinder body 1 from damage. The anti-tipping pull ring 9 is fixedly connected to the elastic rope 8. Rubber baffles 5 are installed at both the front and rear ends of the mounting plate 3, and the rubber baffles 5 are glued to the mounting plate 3. Storage boxes 11 are installed on both sides of the upper surface of the laser rangefinder body 1. A sealing cover 12 is installed at the upper end of the storage box 11, and the sealing cover 12 is connected to the storage box 11 by a slot.

[0027] Working principle: When carrying the device, the operator pulls the telescopic support leg 7 out from the lower end of the mounting base plate 6, then presses the telescopic support leg 7 into the flexible limiting ring 4. Next, the safety cover 14 is placed over the rear end of the laser rangefinder body 1, and the anti-tipping pull ring 9 is secured to the upper part of the operator's clothing via the elastic rope 8 to prevent slippage. The operator can then remove the device by holding the convenient handle 13. When using the device, the operator only needs to remove the telescopic support leg 7 and extend it. Then, the upper end of the telescopic support leg 7 is inserted into the mounting slot 15 at the lower end of the mounting base plate 6. The safety cover 14 and the sealing cover 12 are then opened, and tools are retrieved from the storage box 11. The flexible limiting ring 4, with its flexibility, can cover the telescopic support leg 7, allowing it to be stored outside the laser rangefinder body 1 during transport. This ensures that all components of the device are integrated within the laser rangefinder body 1. Externally, the device is made more compact, reducing its carrying space and making it easier to carry. When the telescopic support legs 7 are stored outside the laser rangefinder body 1, they form a protective frame, enhancing the device's impact resistance and making it safer to carry. Installing the telescopic support legs 7 minimizes the space occupied by the laser rangefinder body 1 while ensuring support, making the device more compact and user-friendly. The side panel rubber filling layer 2 improves the device's impact resistance and protects the sides of the laser rangefinder body 1. The anti-tipping pull ring 9 and elastic rope 8 allow the device to be used in windy weather. The anti-tipping pull ring 9 can be attached to clothing via a rope, so that if the wind blows the device over, the elastic rope 8 provides traction, preventing the laser rangefinder body 1 from contacting the ground and effectively protecting it from damage.
