Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, specifically to a surveying and mapping engineering auxiliary surveying device. Background Technology

[0002] In the field of surveying and mapping engineering, the leveling rod is the core tool for elevation measurement, and its measurement accuracy and ease of use directly affect the quality of engineering surveying and mapping.

[0003] However, traditional leveling rods have two major drawbacks in practical applications: First, due to the lack of an effective leveling correction mechanism, when used on non-ideal flat ground, the leveling rod is prone to tilting due to uneven bottom support, thus affecting measurement accuracy. Second, most existing leveling rods are designed with a fixed length, resulting in large size and inconvenience in carrying. For engineering scenarios that require frequent relocation of measurement points, the bulky leveling rod can increase the workload and may even deform due to collisions during transportation, further affecting measurement accuracy.

[0004] Therefore, a surveying and mapping auxiliary device for surveying and mapping engineering is proposed to solve the problems mentioned above. Utility Model Content

[0024] 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.

[0025] Example:

[0026] Please see Figure 1 - Figure 5 This embodiment of a surveying engineering auxiliary surveying device includes a first leveling rod 1. A second leveling rod 4 is rotatably connected to the first leveling rod 1 via a folding mechanism. The folding mechanism facilitates the storage of the second leveling rod 4 inside the first leveling rod 1, making the leveling rod easier to carry. The first leveling rod 1 is equipped with a leveling mechanism to enhance the leveling rod's horizontal correction function, thereby improving surveying accuracy. The folding mechanism includes a housing 23, which is rotatably connected to the first leveling rod 1. The housing 23 is used to support the installation of the second leveling rod 4, and one end of the housing 23 penetrates the inner wall of the first leveling rod 1. The second leveling rod 4 is fixedly installed at one end of the housing 23. The second leveling rod 4, together with the first leveling rod 1, facilitates auxiliary surveying. A limit block 27 is slidably installed on the inner wall of the housing 23. The limit block 27 is used to support the installation of the connecting rod 25. The connecting rod 25 is fixedly installed at one end of the limit block 27. The connecting rod 25 is used to support the installation of the pull plate 21. One end of the connecting rod 25 passes through the housing 23 and is fixedly installed with the pull plate 21. The pull plate 21 is used to support the installation of the insertion rod 24. The insertion rod 24 is fixedly installed on one side of the pull plate 21. The insertion rod 24 is used to be inserted into the slot 22, thereby achieving the purpose of fixing the second leveling rod 4.

[0027] The leveling mechanism includes a groove 35, which is formed on the first leveling rod 1. A level bubble meter 31 is fixedly installed on the inner wall of the groove 35. The level bubble meter 31 is set up to observe whether the leveling rod is in a vertical state.

[0028] The first leveling rod 1 is U-shaped, and the second leveling rod 4 is long and narrow. The first leveling rod 1 and the second leveling rod 4 are used to assist in surveying.

[0029] The housing 23 is cylindrical in shape and is horizontally positioned to support the sliding of the limiting block 27.

[0030] The limiting block 27 is in the shape of a circular plate, and the connecting rod 25 is in the shape of a square rod. The connecting rod 25 is set horizontally and is used to support the installation of the pull plate 21.

[0031] The pull plate 21 is circular and vertically positioned. The insertion rod 24 is cylindrical and horizontally positioned. The insertion rod 24 is designed to be inserted into the slot 22.

[0032] A spring 26 is fixedly installed on the inner wall of the housing 23. The spring 26 is wound around the connecting rod 25. The spring 26 is used to apply force to the insertion rod 24. One end of the spring 26 is fixedly connected to the inner wall of the housing 23. A slot 22 is provided on the first leveling rod 1. The slot 22 is cylindrical. The slot 22 is used to receive the insertion of the insertion rod 24.

[0033] A dustproof cloth 33 is fixedly installed on the first leveling rod 1. The dustproof cloth 33 is designed to cover the groove 35 when the leveling rod is not in use, so as to prevent dust from adhering and affecting its use. A first Velcro 32 is provided on the dustproof cloth 33, and a second Velcro 34 is fixedly installed on the first leveling rod 1. The first Velcro 32 and the second Velcro 34 are used to fix the dustproof cloth 33 to the surface of the first leveling rod 1.

[0034] When the leveling rod is in use, the bubble level 31 can be used to observe whether the leveling rod is in a vertical position, which helps to improve the accuracy of surveying. When the leveling rod is not in use, the dustproof cloth 33 can be covered to the groove 35 through the first Velcro 32 and the second Velcro 34, thereby achieving the purpose of dust protection for the bubble level 31 and facilitating subsequent use.

[0035] Furthermore, the pull plate 21 can be pulled, which will move the insertion rod 24 until the insertion rod 24 moves out of the slot 22. At this time, the fixation of the box body 23 can be released. Then, the second leveling ruler 4 can be rotated until it is rotated to the inner wall of the first leveling ruler 1. Then, the pull plate 21 can be released. Under the action of the spring 26, the pull plate 21 will drive the insertion rod 24 to be inserted into the slot 22, thereby achieving the purpose of fixing the box body 23 and the second leveling ruler 4. Through the above settings, it is easy to fold the leveling ruler and facilitate its carrying.
