Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of level instrument support, and more specifically, to a support device for a digital level instrument. Background Technology

[0002] In the surveying industry, digital levels, as core equipment for acquiring elevation data, are widely used in topographic surveying, construction monitoring, and other fields. Support devices, as the foundation for the stable operation of digital levels, directly impact the efficiency and flexibility of surveying work due to their portability. Currently, most digital level support devices on the market have significant shortcomings in portability, making it difficult to meet the diverse operational needs of surveyors.

[0003] Most existing digital level support devices are bulky and large in size. Even those with folding designs still exceed ideal portability standards in terms of size and weight. For example, some tripod-style support devices, while capable of folding legs, are cumbersome to fold due to their heavy materials and complex joint structures, and still occupy a significant amount of space when folded, making them unsuitable for long-distance field transport and frequent relocation. Furthermore, the assembly and disassembly methods for the support device and level are not convenient, requiring considerable time and effort from surveyors when changing work locations. The lack of a reasonable portable storage design also makes the device susceptible to component movement, impact damage, and other issues during transport, increasing maintenance costs.

[0004] As surveying and mapping work scenarios continue to expand, especially in environments with complex terrain such as mountainous areas and densely built-up urban areas, the requirements for the portability of support devices are becoming increasingly stringent. Therefore, developing a digital level support device that is easy to carry, disassemble, and store has become crucial for improving the convenience and efficiency of surveying and mapping work. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a support device for a digital level, which solves the technical problem that most existing digital level support devices are bulky and have a large overall size. Even if some products adopt a folding design, the size and weight after folding still exceed the ideal portability standard.

[0006] According to one aspect, at least one embodiment of this disclosure provides a support device for a digital level, comprising:

[0007] The main seat and the auxiliary seat are rotatably connected by a pin.

[0008] The system includes several telescopic legs and a folding connecting assembly, wherein the telescopic legs are all mounted on the main seat, and the folding connecting assembly is located outside the main seat and the auxiliary seat;

[0009] The mounting connection component is disposed on the main seat;

[0010] The folding connection assembly includes a side groove, which is formed on the side surface of the main seat. Both sides of the side groove are open structures. Both ends of the side surface of the auxiliary seat are provided with docking grooves, which are connected to the side groove. A fixed block is provided on one side of the main seat. A pair of movable blocks are slidably connected in the side groove. The telescopic legs are respectively provided on the fixed block and the movable blocks.

[0011] As a further technical solution, both the fixed block and the movable block have connecting grooves on their surfaces, and a rotating block is rotatably connected to the connecting groove via a pin. The telescopic leg is fixed to the lower end face of the rotating block.

[0012] As a further technical solution, the surface of the rotating block is provided with several slots, a sleeve is provided in the connecting slot, a locking block is movably connected to the bottom of the sleeve, a pair of supporting springs are connected between the locking block and the top of the sleeve, and the locking block is inserted into the slot.

[0013] As a further technical solution, the bottom of the main seat is provided with a movable groove, and the side end face of the auxiliary seat is provided with a slot. A support rod is movably connected in the movable groove, and one end of the support rod passes through the main seat and is inserted into the slot.

[0014] As a further technical solution, a pair of pressure springs are connected to the inner end face of the support rod and the movable groove. An ear plate is provided at the bottom of the movable block. A fixing bolt is screwed into the ear plate, and the upper end of the fixing bolt is supported at the bottom of the main seat.

[0015] As a further technical solution, the installation connection assembly includes a circular groove, which is formed on the top of the main seat. Several movable columns are movably connected within the circular groove, and a connecting plate seat is provided at the upper end of each movable column.

[0016] As a further technical solution, a stud is connected to the main seat by a threaded connection, and the upper end of the stud is rotatably fitted into the bottom of the connecting plate seat.

[0017] As a further technical solution, both the side groove and the docking groove have a T-shaped cross-section.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the folding connecting assembly, through the interconnected design of the side groove and the docking groove, allows the movable block to slide between the main seat and the auxiliary seat. Combined with the locking structure of the rotating block and the slot, this enables flexible folding and unfolding of the telescopic legs. The T-shaped cross-section of the side groove and the docking groove ensures that the movable block does not fall off during sliding. The support rod and pressure spring maintain the stability of the main seat and auxiliary seat after unfolding. The ear plate and fixing bolts prevent the movable block from sliding, solving the problem of the large size of existing devices after folding. When folded, the movable block and telescopic legs are neatly stored, and the main seat and auxiliary seat rotate and fit together, significantly reducing the overall volume. This makes it easy for surveyors to carry and move the equipment, especially suitable for operations in complex field terrain, improving the portability and flexibility of the equipment.

[0033] like Figures 1-5 As shown, a support device for a digital level according to an embodiment of the present disclosure is illustrated, comprising:

[0034] The main seat 1 and the auxiliary seat 2 are rotatably connected by a pin.

[0035] Several telescopic legs 3 and a folding connecting assembly 4 are provided. The telescopic legs 3 are all provided on the main seat 1, and the folding connecting assembly 4 is provided outside the main seat 1 and the auxiliary seat 2.

[0036] Mounting connection component 5 is disposed on the main seat 1;

[0037] The folding connecting assembly 4 includes a side groove 4-1, which is formed on the side surface of the main seat 1. Both sides of the side groove 4-1 are open. The side surface of the auxiliary seat 2 has mating grooves 4-2 at both ends, which communicate with the side groove 4-1. A fixed block 4-3 is provided on one side of the main seat 1. A pair of movable blocks 4-4 are slidably connected within the side groove 4-1. Telescopic legs 3 are respectively mounted on the fixed block 4-3 and the movable blocks 4-4. Both the fixed block 4-3 and the movable blocks 4-4 have connecting grooves 4-5 on their surfaces. A rotating block 4-6 is rotatably connected to the connecting groove 4-5 via a pin. The telescopic legs 3 are fixed to the lower end face of the rotating block 4-6. The rotating block 4-6 has several slots 4-7 on its surface. A sleeve 4-8 is provided within the connecting groove 4-5. The bottom of the sleeve 4-8 is movably connected to a locking block 4-9. A pair of support springs 4-10 are connected between the locking block 4-9 and the top of the sleeve 4-8. The locking block 4-9 is inserted into the locking groove 4-7. The bottom of the main seat 1 has a movable groove 4-11. The side end face of the auxiliary seat 2 has a slot 4-12. A support rod 4-13 is movably connected to the movable groove 4-11. One end of the support rod 4-13 passes through the main seat 1 and is inserted into the slot 4-12. A pair of pressure springs 4-14 are connected between the support rod 4-13 and the inner end face of the movable groove 4-11. The bottom of the movable block 4-4 is provided with an ear plate 4-15. A fixing bolt 4-16 is screwed into the ear plate 4-15. The upper end of the fixing bolt 4-16 is supported at the bottom of the main seat 1.

[0038] In some examples, to achieve a foldable and portable design, a folding connection component 4 is designed. This component includes a side groove 4-1 on the side surface of the main seat 1, with openings on both sides providing space for the sliding of the movable block 4-4. The mating grooves 4-2 at both ends of the side surface of the auxiliary seat 2 are connected to the side groove 4-1, allowing the movable block 4-4 to move smoothly between the main seat 1 and the auxiliary seat 2 during folding. A pair of movable blocks 4-4, slidably connected to a fixed block 4-3 on one side of the main seat 1 and within the side groove 4-1, form the mounting base for the telescopic leg 3. The fixed block 4-3 provides a stable support point, while the movable blocks 4-4 can slide flexibly within the side groove 4-1 to adapt to folding and unfolding requirements. The movable blocks 4-4 can be moved centrally into the mating groove 4-2 and merged with both sides of the fixed block 4-3, resulting in a more concentrated structure and easier portability.

[0039] Within the connecting groove 4-5 on the surface of the fixed block 4-3 and the movable block 4-4, a rotating block 4-6 is rotatably connected via a pin. The rotating block 4-6 can rotate freely within the connecting groove 4-5, thereby causing the telescopic leg 3 fixed to its lower end face to change angle. Several slots 4-7 on the surface of the rotating block 4-6 cooperate with the sleeve 4-8, the locking block 4-9, and the support spring 4-10 within the connecting groove 4-5. When the rotating block 4-6 rotates to a suitable angle, the locking block 4-9, under the elastic force of the support spring 4-10, inserts into the slot 4-7, fixing the rotating block 4-6 and thus locking the angle of the telescopic leg 3. The movable groove 4-11 at the bottom of the main seat 1 and the slot 4-12 on the side end face of the auxiliary seat 2 cooperate with the support rod 4-13 and the pressure spring 4-14, which are movably fitted within the movable groove 4-11. When the main seat 1 and the auxiliary seat 2 are folded, the locking block 4-9 can be pulled out from the slot 4-7 without hindering the folding of the main seat 1 and the auxiliary seat 2. Inside the ear plate 4-15 at the bottom of the movable block 4-4, the fixing bolt 4-16, which is connected by threaded screws, can be tightened to support the bottom of the main seat 1, preventing the movable block 4-4 from sliding freely in the side groove 4-1, and further enhancing the structural stability.

[0040] The folding connection assembly 4, through the coordinated operation of the aforementioned components, can conveniently retract multiple telescopic legs 3, while simultaneously folding the main seat 1 and the auxiliary seat 2. When not in use, it reduces the space occupied by the support device, making it easy to carry and transport; when in use, it can be quickly unfolded and stably fixed, providing a reliable support foundation for the digital level.

[0041] like Figures 1-5As shown in the figure, the installation connection component 5 in this embodiment includes a circular groove 5-1, which is formed on the top of the main seat 1. A plurality of movable columns 5-2 are movably fitted inside the circular groove 5-1. A connecting plate seat 5-3 is provided at the upper end of the movable column 5-2. A stud 5-4 is threadedly connected inside the main seat 1. The upper end of the stud 5-4 is rotatably fitted inside the bottom of the connecting plate seat 5-3.

[0042] In some examples, to achieve a stable installation of the level, a mounting connection assembly 5 is designed. This assembly includes a circular groove 5-1 on the top of the main seat 1, inside which several movable columns 5-2 are movably fitted. The movable columns 5-2 can move up and down within the circular groove 5-1, and the connecting plate seat 5-3 connected to their upper ends can rise and fall synchronously with the movable columns 5-2. A stud 5-4 is threadedly connected inside the main seat 1, and its upper end is rotatably fitted into the bottom of the connecting plate seat 5-3. When the stud 5-4 is rotated, due to the threaded drive, the stud 5-4 will move up and down within the main seat 1, thereby driving the connecting plate seat 5-3 to rise or fall.

[0043] When installing a digital level, rotate stud 5-4 to raise the connecting plate 5-3, placing the level on it. The flat surface of the connecting plate 5-3 provides a reference surface for the level. By precisely adjusting the height of the connecting plate 5-3 using stud 5-4, the level can be positioned in a suitable horizontal measurement position. The tight fit between the connecting plate 5-3, the movable column 5-2, and the stud 5-4 ensures that the level is stably mounted on the support device during measurement, preventing wobbling or displacement, thus providing stable and reliable support for accurate measurements with the digital level.

[0044] For example, such as Figure 4 As shown, both the side groove 4-1 and the docking groove 4-2 have a T-shaped cross-section.

[0045] In some examples, the T-shaped structure of the side groove 4-1 and the docking groove 4-2 prevents the movable block 4-4 from falling off during the sliding process between the side groove 4-1 and the docking groove 4-2, making the connected structure more stable and secure.

[0046] In actual use: The main seat 1 and auxiliary seat 2 are rotated and unfolded via a pin, connecting the mating groove 4-2 on the side surface of the auxiliary seat 2 with the side groove 4-1 of the main seat 1. The sliding movable block 4-4 moves from the mating groove 4-2 into the side groove 4-1. The fixed block 4-3 and the rotating block 4-6 on the movable block 4-4 are adjusted to allow the telescopic leg 3 to rotate around the pin to a suitable angle. The locking block 4-9, under the action of the support spring 4-10, inserts into the locking groove 4-7 of the rotating block 4-6 to fix the telescopic leg 3. The rotating fixing bolt 4-16 supports the movable block 4-4 at the bottom of the main seat 1. The support rod 4-13 is pressed to insert into the slot 4-12 of the auxiliary seat 2, and the pressure spring 4-14 supports and maintains stability. The digital level is placed on the connecting plate seat 5-3 on top of the main seat 1. The rotating stud 5-4 drives the movable column 5-2 to rise and fall via threaded transmission. The height of the connecting plate seat 5-3 is adjusted, and the level is fixed on the connecting plate, completing the installation. After use, pull out the support rod 4-13, loosen the fixing bolt 4-16, slide the movable block 4-4 back into the side groove 4-1, pull out the locking block 4-9 to fold the telescopic leg 3, the movable block 4-4 into the docking groove 4-2, rotate the main seat 1 and the auxiliary seat 2 to fold, reducing the size for easy carrying.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
