Description

Technical Field

[0001] This utility model relates to the field of surveying equipment support technology, and in particular to a stable support frame for outdoor multi-terrain applications. Background Technology

[0002] In surveying and mapping work, outdoor operations account for a large proportion, covering multiple fields such as topographic mapping, engineering surveying, and geological investigation. As a core supporting device for optical surveying equipment (such as levels, total stations, and theodolites), the stability of the support frame directly determines the accuracy and reliability of the surveying data. Existing support frames have a single type of support end, usually optimized only for a certain type of terrain: support frames designed for soil terrain often have tapered inserts at the support end. Although they can be anchored by inserting into the soil, when used on smooth, hard surfaces such as cement floors and stone slab roads, the tapered inserts cannot effectively adhere to the ground, easily causing slippage, tilting, or even equipment tipping over and being damaged. Support frames adapted for hard surfaces often have flat rubber pads at the support end, relying on friction for anti-slip. However, when transferred to soil or loose sandy terrain, the flat pads have a small contact area with the ground and insufficient grip. The support point is prone to sinking due to soil subsidence, causing the equipment to shift horizontally and affecting surveying accuracy. When facing mixed and complex terrains such as mountainous gravel areas and soft soil in fields... Utility Model Content

[0003] This utility model relates to a stable support frame for outdoor multi-terrain applications, which solves the problem that the support end of existing optical surveying equipment support frames has a single shape, is only optimized for a certain type of terrain, and cannot be adapted and switched according to different terrains.

[0005] Furthermore, a support plate is fixedly installed on the bottom of the outer circumference of the rotating main shaft. The bottom end of the support plate adopts a semi-circular structure and a storage notch is opened at the bottom of the support plate. A shaft hole b is opened on the left and right end faces of the support plate relative to the axis center of the semi-circular structure, which is connected to the storage notch. A rotating secondary shaft is rotatably installed inside the storage notch.

[0006] Furthermore, the length of the rotating secondary shaft is consistent with the width of the receiving slot. A rotating shaft b is fixedly installed at the center of the right end face of the rotating secondary shaft. The rotating shaft b is inserted into the shaft hole a located on the right side and is rotatably connected to it. A stud a is fixedly installed at the center of the left end face of the rotating main shaft. The stud a passes through the shaft hole b located on the left side, and a locking nut a is threaded on the stud a.

[0007] Furthermore, a plug-in support cone is fixedly installed on the top of the outer peripheral surface of the rotating sub-shaft. When the plug-in support cone faces upward, it is completely retracted into the receiving notch and does not contact the inner end face of the receiving notch at this time.

[0008] Furthermore, an extension stud is fixedly installed on the bottom of the outer circumferential surface of the rotating sub-shaft, and a rubber support block with a hemispherical structure is fixedly installed on the bottom end face of the extension stud; when the extension stud faces upward, the extension stud is completely retracted into the receiving notch, and at this time neither the extension stud nor the rubber support block contacts the inner end face of the receiving notch.

[0010] This utility model provides a stable support frame for outdoor multi-terrain applications, which has the following advantages: This invention can flexibly adapt to different ground types to provide support. In soil terrain, the conical structure of the plug-in support cone can easily penetrate the soil and anchor it, preventing the support frame from shifting. On smooth, hard ground, the hemispherical rubber support block, thanks to the high friction of the rubber material, can effectively prevent slippage, and the hemispherical design can adapt to minor ground protrusions, ensuring a tight fit between the support surface and the ground. For loose soil, by adjusting the support auxiliary block, the annular rubber support pad can contact the ground, using a large contact area to disperse pressure and prevent the support point from sinking due to soil subsidence, thus comprehensively meeting the stable support needs of different scenarios.

[0011] When not in use, the rotating sub-shaft can be rotated to the position where the insert support cone faces upward, so that the insert support cone is completely stored inside the storage slot of the support plate. On the one hand, this effectively avoids accidental contact between the insert support cone and the operator during carrying and transportation due to its sharp nature, thereby eliminating safety hazards such as scratches and punctures, and greatly improving the safety of equipment use and handling. On the other hand, it can prevent the sharp support cone from causing scratches, dents and other damage to the surface of other equipment due to collisions and friction when stored or transported together with other tools and equipment, significantly reducing equipment maintenance costs and storage risks.

[0017] The rotating secondary shaft 203 has a fixedly installed insertion support cone 204 on its top outer peripheral surface. When the insertion support cone 204 faces upward, it is completely retracted into the receiving notch 202 and does not contact the inner end face of the receiving notch 202. An extension stud 207 is fixedly installed on the bottom outer peripheral surface of the rotating secondary shaft 203. A hemispherical rubber support block 2010 is fixedly installed on the bottom end face of the extension stud 207.

Contact; A circular support auxiliary block 208 is threadedly installed on the extension stud 207. A threaded through hole 2014 is opened at the axial center of the support auxiliary block 208, and the threaded through hole 2014 is threadedly connected to the extension stud 207; An annular rubber support pad 209 is fixedly installed on the bottom end face of the support auxiliary block 208.

[0018] The working principle of this embodiment: During adjustment, loosen the locking nut b2013, and rotate the main shaft 2 within the rotational fit notch 104 through the rotational fit between the rotating shaft a2011 and the stud b2012 and the shaft hole a105, so as to adjust it to the required support angle to adapt to the current outdoor terrain and ensure that the fixed seat 1 remains horizontal. Then tighten the locking nut b2013, and fix the position of the rotating main shaft 2 by the compression of the locking nut b2013 and the end face of the rotating auxiliary seat 103. Different support methods are selected depending on the terrain. The specific operation is as follows: When the survey location is soil, loosen the locking nut a206 and rotate the rotating sub-shaft 203 to the "insertion support cone 204 facing down" state. At this time, the extension stud 207 and the rubber support block 2010 are stored inside the storage notch 202 with the extension stud facing up. Tighten the locking nut a206 to lock it in place. Then insert the insertion support cone 204 into the soil. Utilize the soil penetration of the cone structure to penetrate deep into the soil and form an anchoring effect. When the surveying location is a smooth, hard surface, loosen the locking nut a206 and rotate the rotating sub-shaft 203 to the position where the rubber support block 2010 faces downward. At this time, the insert support cone 204 faces upward and is stored inside the storage notch 202. Tighten the locking nut a206 to lock it in place. The hemispherical rubber support block 2010 contacts the hard surface. The high friction of the rubber material prevents the support frame from sliding. At the same time, the hemispherical design can slightly adapt to the small protrusions on the ground to ensure that the support surface fits. When the survey site has loose soil, and the insertion support cone 204 is prone to tilting due to soil collapse after insertion, loosen the locking nut a206 and rotate the rotating sub-shaft 203 to the "extension stud 207 facing down" state. At this time, the insertion support cone 204 is stored inside the storage notch 202 with the insertion facing up. Tighten the locking nut a206 to lock it in place. Then, the threaded through hole 2014 is threadedly installed with the extension stud 207. Adjust the position of the support auxiliary block 208 up and down along the extension stud 207 so that the annular rubber support pad 209 faces down and is lower than the rubber support block 2010. Then, the annular rubber support pad 209 at the bottom of the support auxiliary block 208 contacts the soil surface. It has a large contact area with the soil surface, which can disperse the pressure of the support frame on the soil and prevent the support point from sinking into the soil. At the same time, the annular rubber material has both friction and a certain elasticity, which can adapt to the slight unevenness of the soil surface and prevent the support point from sliding or collapsing. When not in use, loosen the locking nut a206 and rotate the rotating sub-shaft 203 to the position where the "insertion support cone 204 faces upward". At this time, the insertion support cone 204 is completely stored in the storage notch 202 of the support plate 201. After being folded up, the sharp insertion support cone 204 is completely wrapped in the storage notch 202, which can prevent scratching the operator or damaging other equipment when carrying it.
