Description

Technical Field

[0001] This utility model relates to the field of forestry site surveying technology, specifically to a device for forestry site design and surveying. Background Technology

[0002] In order to understand and grasp the actual situation of forestry sites, including topography, landforms, vegetation, water resources, etc., and to assess the distribution, growth status and degree of threat to forestry resources, it is usually necessary to conduct site surveys to obtain this information. This information provides a scientific basis for subsequent forestry planning, design, development and management.

[0003] Patent CN219798336U discloses an outdoor surveying device for forestry site design, including a rangefinder. The rangefinder has a locking device on its bottom wall for fixing its position. This locking device includes a connecting block. By using this locking device, when connecting the rangefinder to a fixing plate, the movable block is pressed against the first spring, causing it to fully enter the locking cavity. The connecting block is then placed inside the fixing plate cavity, aligned with a hole. The first spring then ejects the movable block out of the locking cavity, thus limiting the position of the rangefinder. To remove the rangefinder, a push plate is pushed inwards, moving a movable rod. This movement of the rod moves the movable plate, pushing the movable block into the first spring cavity, allowing the rangefinder to be lifted upwards.

[0004] However, the following problems still exist:

[0005] Forestry sites are usually located in mountainous areas, forests, or other complex terrains. These areas often have unique climate, soil, and vegetation conditions, and the soil is relatively loose or slippery. When the above-mentioned device is deployed for measurement, the bottom of the telescopic rod of the support will be directly on the loose or slippery soil, which is prone to slipping and has poor stability, thus affecting the measurement work. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a forestry site design and surveying device that improves the stability of the telescopic pole on soft or slippery soil and prevents slippage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A device for forestry site design and surveying includes a rangefinder body and a telescopic support. The bottom side wall of the telescopic support has a hinge groove, and a support plate is provided on one side of the hinge groove. A hinge rod is fixedly connected to the side wall of the support plate, and the hinge rod is rotatably connected to the hinge groove. T-shaped sliding grooves are provided on both sides of the support plate, and a T-shaped slider is slidably connected to the inner wall of the T-shaped sliding groove. A tapered rod is fixedly connected to the bottom surface of the T-shaped slider, and a limiting device is provided on one side of the T-shaped slider located inside the T-shaped sliding groove.

[0009] Preferably, the limiting device includes a spring groove opened in the side wall of the T-shaped slider inside the T-shaped groove, and a limiting spring is provided inside the spring groove. The two ends of the limiting spring are provided with limiting balls, and multiple sets of symmetrical limiting ball grooves are opened in the side wall of the T-shaped groove located on one side of the limiting ball.

[0010] Preferably, one of the T-shaped sliders has a threaded groove on its side wall, and a tapered bolt is threaded into the threaded groove. A reinforcing threaded groove is provided at the center of the support plate.

[0011] Preferably, a U-shaped handle is fixedly connected to one end of the conical bolt.

[0012] Preferably, the upper surfaces of both sets of T-shaped sliders are provided with grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a rangefinder body, a telescopic bracket, a hinge groove, a support plate, a hinge rod, a T-shaped slide, a T-shaped slider, a conical rod, and a limiting device. First, the telescopic bracket is deployed. The support plate, through the hinge rod and hinge groove, ensures that the conical rod at the bottom of the T-shaped slider in the T-shaped slide is perpendicular to the soil surface. Then, stepping on the support plate and the T-shaped slider causes the conical rod at the bottom of the T-shaped slider to penetrate into the soft or slippery soil, thus gripping the soil firmly, stabilizing the telescopic bracket, improving support stability, and preventing slippage. Furthermore, the T-shaped slider can be pulled to adjust the distance between the two sets of conical rods, facilitating deeper penetration into the soil. The limiting device automatically fixes the moved T-shaped slider. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-3 A device for forestry site design and surveying includes a rangefinder body 1 and a telescopic support 2. The bottom side wall of the telescopic support 2 is provided with a hinge groove 3, and a support plate 5 is provided on one side of the hinge groove 3. A hinge rod 4 is fixedly connected to the side wall of the support plate 5, and the hinge rod 4 is rotatably connected to the hinge groove 3. T-shaped grooves 6 are provided on both sides of the support plate 5, and a T-shaped slider 7 is slidably connected to the inner wall of the T-shaped groove 6. A tapered rod 8 is fixedly connected to the bottom surface of the T-shaped slider 7, and a limiting device is provided on one side of the T-shaped slider 7 located inside the T-shaped groove 6.

[0021] As can be seen from the above structure, by setting up the rangefinder body 1, telescopic bracket 2, hinge groove 3, support plate 5, hinge rod 4, T-shaped slide 6, T-shaped slider 7, conical rod 8 and limiting device, etc., the telescopic bracket 2 is first unfolded. At this time, the support plate 5, through the hinge rod 4 and hinge groove 3, makes the conical rod 8 on the bottom surface of the T-shaped slider 7 in the T-shaped slide 6 perpendicular to the soil surface. Then, stepping on the support plate 5 and the T-shaped slider 7 makes the conical rod 8 on the bottom surface of the T-shaped slider 7 penetrate into the soft or slippery soil, thereby gripping the soil, stabilizing the telescopic bracket 2, improving the support stability, and preventing slippage. The T-shaped slider 7 can be pulled according to the usage requirements to adjust the distance between the two sets of conical rods 8, so that the conical rod 8 can penetrate into the soil. The limiting device will automatically fix the T-shaped slider 7 after it is moved.

[0022] Furthermore, the limiting device includes a spring groove 9 formed on the side wall of the T-shaped slider 7 inside the T-shaped groove 6, and a limiting spring 10 is provided inside the spring groove 9. The two ends of the limiting spring 10 are provided with limiting balls 11, and multiple sets of symmetrical limiting ball grooves 12 are formed on the side wall of the T-shaped groove 6 located on one side of the limiting balls 11. By setting the T-shaped slider 7, spring groove 9, limiting spring 10, limiting balls 11 and limiting ball grooves 12 in cooperation, when the T-shaped slider 7 is moved, the moving T-shaped slider 7 will drive the limiting balls 11 at both ends of the limiting spring 10 in the spring groove 9 to move. The limiting balls 11 will roll along the side wall of the limiting ball groove 12 and squeeze the limiting spring 10 to move backward. When the T-shaped slider 7 moves to the designated position, the limiting spring 10 will push the limiting balls 11 to slide into the symmetrical limiting ball grooves 12, thereby fixing the T-shaped slider 7 and preventing the T-shaped slider 7 from moving randomly. The operation is simple and convenient.

[0023] Furthermore, one of the T-shaped sliders 7 has a threaded groove 13 on its side wall, and a tapered bolt 14 is threadedly connected inside the threaded groove 13. A reinforcing threaded groove 15 is provided at the center of the support plate 5. By using the threaded groove 13, tapered bolt 14 and reinforcing threaded groove 15 in combination, after the position of the support plate 5 is fixed, the tapered bolt 14 can be rotated out of the threaded groove 13. Then, the tapered bolt 14 is rotated down along the reinforcing threaded groove 15 and inserted into the soft or moist soil. At this time, the tapered bolt 14 will penetrate deeper into the soil than the tapered rod 8, improving the fixing effect. When the tapered bolt 14 is not needed, the tapered bolt 14 can be rotated out of the reinforcing threaded groove 15. Then, the tapered bolt 14 is threadedly connected to the threaded groove 13, which facilitates the placement of the tapered bolt 14.

[0024] Furthermore, a U-shaped handle 16 is fixedly connected to one end of the conical bolt 14; by providing the U-shaped handle 16, it is convenient to rotate the conical bolt 14.

[0025] Furthermore, the upper surfaces of both sets of T-shaped sliders 7 are provided with grooves 17; by providing grooves 17, it is convenient to pull the T-shaped sliders 7 to move, thereby improving the ease of operation.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
