Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, and more particularly to an engineering measurement tripod which is convenient for leveling. Background Art

[0002] A tripod is a support frame used to stabilize a camera or measuring tool, providing a stable and flat support in any scenario. Tripods can be classified into various types based on their material, including wood, high-strength plastic, aluminum alloy, steel, volcanic stone, and carbon fiber.

[0003] After searching, the existing patent (publication number: CN116972303B) discloses a tripod for engineering surveying that is easy to level, including a tripod with a pan head and a supporting leg, the supporting leg is rotatably connected to the pan head, and a sliding adjuster is installed on the other end of the supporting leg. The sliding adjuster includes a support base and a sliding adjustment plate slidably connected to the support base. The direction in which the sliding adjustment plate slides on the support base is consistent with the direction in which the supporting leg rotates on the pan head, and a drive locking mechanism is provided on the sliding adjustment plate. This invention achieves the purpose of adjusting the level of the pan head by setting a sliding adjustment plate and a support base, and by sliding the sliding adjustment plate on the support base. And there is no need for the user to lift the supporting leg or even take his eyes off the circular level bubble to perform leveling. When using the sliding method for leveling, the leveling action is in a continuous process, which greatly improves the accuracy of one-time leveling, thereby improving work efficiency. In the process of realizing this utility model, the inventor found that the prior art has the following problems:

[0004] Existing tripods are often exposed to dust, moisture and other impurities in outdoor or experimental environments. During use, the adjustable joints or slides have gaps between the joints and the adjustable parts, which are often places where dirt hides. Dust, moisture, mud or other pollutants easily accumulate in these hidden places, affecting the flexibility and service life of the equipment. In addition, engineering measurement projects are often carried out outdoors and require measurements in different environments. This means that users have to carry equipment back and forth between different environments, wasting time and energy when adjusting the equipment when moving locations. In different measurement environments, the ground may have slight height differences, unevenness or other obstacles, resulting in time-consuming repositioning and multiple instrument movements, which is also prone to errors.

[0005] Therefore, in order to solve the above problems, an engineering measurement tripod which is easy to level is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides an engineering surveying tripod that is easy to level, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an engineering surveying tripod that is easy to level, comprising a mounting plate, a telescopic rod, an external thread, and a leveling bolt, wherein a rotating shaft is provided at the center of the upper end surface of the mounting plate, a support rod is provided on the upper end surface of the rotating shaft, the telescopic rod is provided at the lower end of the mounting plate, the telescopic rod is provided in three groups, and a fixing plate is provided on the lower end surface of each of the telescopic rods, and the leveling bolt is provided in the inner cavity of the fixing plate;

[0008] The outer surface of the upper end of the telescopic rod is provided with an external thread, the inner cavity of the mounting plate is provided with a first internal thread, the first internal thread is provided with three groups, and the outer surface of the telescopic rod is provided with a scale.

[0009] Preferably, the inner cavity of the fixing plate is provided with a second internal thread, and the second internal thread is threadedly connected to the leveling bolt.

[0010] Preferably, the lower end of the leveling bolt is connected to a limiting pin, and the limiting pin is made of alloy and has a barb-like shape.

[0011] Preferably, the positions of the three groups of telescopic rods correspond to each other in a triangle, and two ends of each group of telescopic rods are respectively connected to the mounting plate and the fixing plate.

[0012] Preferably, the outer diameters of the thread groove and the fixing hole are the same, and the fixing hole and the thread groove are located at the same position.

[0013] Preferably, the upper end surface of the support rod is provided with a threaded connector, and the rotating shaft 2 and the support rod are movably connected.

[0014] The technical effects and advantages of this utility model are:

[0015] 1. Compared with the existing technology, the engineering surveying tripod that is easy to level is designed with a detachable telescopic rod, so that each part of the tripod can be cleaned and maintained separately. If a part is severely worn, it can be easily disassembled and replaced, ensuring that the equipment can always achieve good leveling performance and keep the equipment in the best condition, avoiding the leveling effect affected by dirt or damage. After disassembly, it is easy for users to carry and can be more easily carried to the appropriate location, so that users can quickly start work.

[0016] 2. Compared with the existing technology, this easy-to-level engineering surveying tripod uses the leveling bolts to achieve detailed height changes with each rotation. Users can complete the leveling work with a simple turn, reducing the dependence on complex adjustment tools and improving the user experience. The limit pins can effectively adapt to uneven surfaces, allowing users to make fine adjustments according to actual needs to ensure that the equipment operates in an ideal state.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4 The illustrated embodiment of an engineering surveying tripod for easy leveling comprises a mounting plate 1, a telescopic rod 6, an external thread 7, and a leveling bolt 11. A rotating shaft 2 is provided at the center of the upper end surface of the mounting plate 1, a support rod 3 is provided on the upper end surface of the rotating shaft 2, and the telescopic rod 6 is provided at the lower end of the mounting plate 1. The telescopic rod 6 is provided in three groups, and a fixing plate 9 is provided on the lower end surface of each of the telescopic rods 6. The leveling bolt 11 is provided in the inner cavity of the fixing plate 9.

[0025] The outer surface of the upper end of the telescopic rod 6 is provided with an external thread 7, the inner cavity of the mounting plate 1 is provided with a first internal thread 5, the first internal thread 5 is provided with three groups, and the outer surface of the telescopic rod 6 is provided with a scale 8.

[0026] Among them: the support rod 3 bears the weight of the measuring tool and rotates through the rotating shaft 2. When leveling is required, the size is adjusted according to the scale 8 on the surface of the telescopic rod 6, so as to facilitate precise leveling. When cleaning, maintenance or carrying and moving is required, it is only necessary to rotate the three groups of telescopic rods 6 so that the outer thread 7 at the upper end rotates along the first inner thread 5 on the surface of the mounting plate 1, so that it can be separated from the mounting plate 1 and disassembled, and the leveling bolt 11 can be taken out from the fixing plate 9. The volume of the tripod is greatly reduced, making the entire device more convenient to carry and store, and convenient to clean and maintain separately. When reassembly is required, the user only needs to align the telescopic rod 6 with the first inner thread 5 of the mounting plate 1, gently rotate the telescopic rod 6 until its outer thread 7 engages with the first inner thread 5, and finally reinstall the leveling bolt 11 to complete the assembly.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0029] As a preferred embodiment, the external thread 7 and the first internal thread 5 are engaged with each other, and each set of external threads 7 protrudes from the inner surface of the first internal thread 5; further, the external thread 7 is engaged with the first internal thread 5, so that the external thread 7 is fixed in its inner cavity for installation.

[0030] As a preferred embodiment, the inner cavity of the fixing plate 9 is provided with a second internal thread 10, and the second internal thread 10 is threadedly connected to the leveling bolt 11; further, the second internal thread 10 is used to install the leveling bolt 11, and through the threaded connection with the leveling bolt 11, the leveling bolt 11 can be conveniently installed and disassembled on its inner surface.

[0031] As a preferred embodiment, the lower end of the leveling bolt 11 is connected to a limiting pin 12, and the material of the limiting pin 12 is alloy, and the shape of the limiting pin 12 is barbed; further, the limiting pin 12 made of alloy provides strong grip and support, and enhances wear resistance. Due to its spike-like shape, when providing support, the contact area with the ground is reduced, and it can adapt to uneven ground, making it convenient to tilt at an angle.

[0032] As a preferred embodiment, the positions of the three groups of telescopic rods 6 correspond to each other in a triangle, and the two ends of each group of telescopic rods 6 are respectively connected to the mounting plate 1 and the fixed plate 9; further, the three groups of telescopic rods 6 provide a strong three-legged support, and each group of telescopic rods 6 is connected between the mounting plate 1 and the fixed plate 9 to form a connection.

[0033] As a preferred embodiment, the upper end face of the support rod 3 is provided with a threaded connector 4, and the rotating shaft 2 and the support rod 3 are movably connected; further, the threaded connector 4 is used to provide an interface for installation with the measuring equipment, and the rotating shaft 2 can make the support rod 3 rotate.

[0034] The working process of the present invention is as follows: first, the support rod 3 bears the weight of the measuring tool, is connected to the measuring device through the threaded connector 4, and is rotated by the rotating shaft 2. When leveling is required, the size is adjusted according to the scale 8 on the surface of the telescopic rod 6, so as to facilitate accurate leveling. When cleaning, maintenance or carrying and moving are required, it is only necessary to rotate the three sets of telescopic rods 6 so that the external thread 7 at the upper end rotates along the first internal thread 5 on the surface of the mounting plate 1, and it can be separated and disassembled from the mounting plate 1. When reassembly is required, the user only needs to align the telescopic rod 6 with the first internal thread 5 of the mounting plate 1 and gently rotate the telescopic rod 6 until it is level. The external thread 7 is engaged with the first internal thread 5, and finally the leveling bolt 11 is reinstalled. When supporting, the adjusting bolt 11 is engaged with the second internal thread 10 in the fixing plate 9, thereby cooperating with the limit pin 12 to support the tripod. The limit pin 12 can reduce the contact area with the ground, thereby adapting to the uneven ground. The two can be disassembled and removed by simply rotating the leveling bolt 11. The user can achieve delicate height changes of the tripod by rotating the leveling bolt forward and backward along the second internal thread 10. The user only needs to turn it simply to complete fine-tuning work. The above is the working principle of this engineering measurement tripod that is easy to level.

[0035] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
