Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle measurement, in particular to a support frame. Background Art

[0002] Drone surveying refers to the use of drone-mounted sensors (such as cameras and laser scanners) to acquire images or data of a target area, process these images using specialized software, and ultimately generate geospatial information products such as 3D models, orthophotos, and digital elevation models (DEMs). During drone surveying, a support frame is often used to provide a stable and reliable platform for safe takeoff and landing. The primary function of the support frame is to support and protect the various components of the drone, ensuring its stability and safety during flight. The use of a support frame ensures the stability and safety of the drone and its surveying equipment during the measurement process, preventing the equipment from tilting or collapsing, thereby improving the accuracy and reliability of the measurement.

[0003] In the prior art, when a support frame is used to support a drone for measurement, the support frame is generally set up below the drone to achieve support. Since the height of the support frame is generally fixed, the support frame cannot be flexibly extended or retracted during the support process to achieve adjustment of the support frame, which makes the support for the drone not flexible enough and the support frame cannot be well stored. Therefore, in order to solve the above problems, a support frame is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a support frame to solve the problem mentioned in the above background technology that the height of the support frame is generally fixed, which makes it impossible to flexibly extend and retract the support frame during the support process to achieve adjustment of the support frame, resulting in insufficient flexibility in supporting the drone and the inability to store the support frame well.

[0005] To achieve the above object, the present invention provides the following technical solution: a support frame, comprising a frame body, the frame body comprising a fixing frame, a first support rod being fixedly connected to a lower surface of the fixing frame, a second support rod being movably connected to a surface of the first support rod, and a fixing rod being fixedly connected to a surface of the second support rod;

[0006] The surface of the fixed rod is provided with a telescopic mechanism, and the telescopic mechanism includes a rotating rod, which is movably connected to the inner side of the fixed rod, the bottom end of the rotating rod is fixedly connected with a first conical tooth, the inner side of the fixed rod is movably connected with a forward and reverse screw, the surface of the forward and reverse screw is fixedly connected with a second conical tooth, the surface of the forward and reverse screw is threadedly connected with a moving block, and a limiting groove is provided on the surface of the first support rod.

[0007] Preferably, the telescopic mechanism also includes a slider, which is fixedly connected to the surface of the moving block, a sliding groove is provided on the inner wall of the fixed rod, a sliding block is fixedly connected to the surface of the first support rod, and a sliding groove is provided on the inner wall of the second support rod.

[0008] Preferably, the movable blocks are in two groups and move on the inner side of the fixed rod, and the limiting grooves are in eleven groups and are evenly opened on the surface of the first support rod.

[0009] Preferably, the moving block is movably connected to the sliding groove via a slider, one end of the sliding block is fixedly connected to the first support rod, and the other end of the sliding block is movably connected to the sliding groove.

[0010] Preferably, an auxiliary mechanism is provided on the surface of the second support rod, and the auxiliary mechanism includes a fixed block, the fixed block is fixedly connected to the surface of the second support rod, the inner side of the fixed block is movably connected with a connecting block, the lower surface of the connecting block is fixedly connected to a connecting rod, the bottom end of the connecting rod is fixedly connected to a support block, the lower surface of the support block is fixedly connected to a rubber block, the inner side of the fixed block is threadedly connected to a threaded rod, and a slot is provided on the inner side of the connecting block.

[0011] Preferably, the fixing blocks are in four groups and connected to the second support rods respectively, the connecting blocks are in four groups and connected to the fixing blocks respectively, and the rubber blocks are evenly distributed on the lower surface of the support blocks.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The first conical tooth is driven to rotate by the rotating rod, so that the second conical tooth can drive the forward and reverse screws to rotate, and then the moving block moves, which can be inserted into and separated from the limit slots. By inserting and separating the moving block and different limit slots, the first support rod can be extended and retracted on the inner side of the second support rod, and then the height of the support frame can be adjusted and fixed, so that the use of the support frame is more flexible and better supports the measurement of the drone. At the same time, by storing the first support rod in the second support rod, the volume of the support frame can be reduced, making it more convenient to carry.

[0014] By setting the support block, the support frame can be auxiliary supported. The setting of the rubber block can increase the friction between the support block and the ground, so that the support is more stable and not prone to displacement, which can better ensure the accuracy of measurement. At the same time, by rotating the threaded rod, the threaded rod and the slot are engaged and separated, which makes it easy to remove the connecting block for storage and also facilitates the replacement of the entire support block.

[0023] 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.

[0024] See also Figure 1-7 , an embodiment provided by the utility model:

[0025] A support frame includes a frame body, the frame body includes a fixing frame 1, a first support rod 11 is fixedly connected to the lower surface of the fixing frame 1, a second support rod 12 is movably connected to the surface of the first support rod 11, and a fixing rod 13 is fixedly connected to the surface of the second support rod 12. Through the setting of the fixing rod 13, two groups of second support rods 12 can be connected. Through the cooperation of the first support rod 11 and the second support rod 12, a drone can be supported, which is convenient for ensuring the stability and safety of the drone and its measuring equipment during the measurement process;

[0026] The surface of the fixed rod 13 is provided with a telescopic mechanism, which includes a rotating rod 2, which is movably connected to the inner side of the fixed rod 13, and the bottom end of the rotating rod 2 is fixedly connected to the first conical tooth 21, and the inner side of the fixed rod 13 is movably connected with a forward and reverse screw 22, and the surface of the forward and reverse screw 22 is fixedly connected to the second conical tooth 23, and the surface of the forward and reverse screw 22 is threadedly connected to a moving block 24. A limiting groove 25 is provided on the surface of the first support rod 11, and the rotation of the forward and reverse screw 22 can drive the moving block 24 to move horizontally, and then the moving block 24 and different limiting grooves 25 can be inserted into each other, so that the length of the first support rod 11 and the second support rod 12 can be adjusted, which is convenient for the first support rod 11 and the second support rod 12 to be extended and retracted, making the storage, carrying and use of the support frame more flexible and convenient.

[0027] Furthermore, the telescopic mechanism also includes a slider 26, which is fixedly connected to the surface of the moving block 24, a sliding groove 27 is provided on the inner wall of the fixed rod 13, a sliding block 28 is fixedly connected to the surface of the first support rod 11, and a sliding groove 29 is provided on the inner wall of the second support rod 12. Through the opening of the sliding groove 27, the moving block 24 is facilitated to slide on the inner side of the sliding groove 27 through the slider 26, thereby preventing the moving block 24 from deviating under the action of the forward and reverse screws 22, and ensuring that the moving block 24 is stably inserted and separated from the limit groove 25.

[0028] Furthermore, the movable blocks 24 are movable in two groups on the inner side of the fixed rod 13, and the limiting grooves 25 are evenly opened in eleven groups on the surface of the first support rod 11. By plugging the movable blocks 24 into different limiting grooves 25, the lengths of the first support rod 11 and the second support rod 12 can be adjusted and fixed, so that the support of the drone by the first support rod 11 and the second support rod 12 can be more flexible.

[0029] Furthermore, the movable block 24 is movably connected to the slider 26 and the sliding groove 27, one end of the sliding block 28 is fixedly connected to the first support rod 11, and the other end of the sliding block 28 is movably connected to the sliding groove 29. Through the cooperation of the sliding block 28 and the sliding groove 29, the movement of the first support rod 11 in the second support rod 12 can be limited, thereby ensuring the stability of the movement of the first support rod 11 in the second support rod 12.

[0030] Furthermore, an auxiliary mechanism is provided on the surface of the second support rod 12, which includes a fixed block 3, which is fixedly connected to the surface of the second support rod 12, and a connecting block 31 is movably connected to the inner side of the fixed block 3, and a connecting rod 32 is fixedly connected to the lower surface of the connecting block 31, and a supporting block 33 is fixedly connected to the bottom end of the connecting rod 32, and a rubber block 34 is fixedly connected to the lower surface of the supporting block 33, and a threaded rod 35 is threadedly connected to the inner side of the fixed block 3, and a slot 36 is provided on the inner side of the connecting block 31. Through the setting of the support block 33, the drone can be auxiliary supported, thereby achieving better supporting effect. At the same time, through the action of the threaded rod 35 and the opening of the slot 36, it is convenient to remove and store the support block 33 as a whole, or to replace it.

[0031] Furthermore, the fixing blocks 3 are divided into four groups and connected to the second support rod 12, the connecting blocks 31 are divided into four groups and connected to the fixing blocks 3, and the rubber blocks 34 are evenly distributed on the lower surface of the support blocks 33. By setting the rubber blocks 34, the friction between the support blocks 33 and the ground can be increased, thereby making the support of the drone more stable and enabling better measurement.

[0032] Working principle: when in use, the rotating rod 2 is rotated, the first conical tooth 21 rotates under the action of the rotating rod 2, and then the second conical tooth 23 rotates under the action of the first conical tooth 21 and drives the forward and reverse screw rod 22 to rotate. The moving block 24 is limited by the slider 26 and the slide groove 27, and moves inside the fixed rod 13 under the action of the forward and reverse screw rod 22, so that the moving block 24 can be inserted into and separated from the limiting groove 25, and then the slider 26 slides inside the slide groove 27. Through the separation of the moving block 24 and the limiting groove 25, the first support rod 11 can be extended and retracted in the second support rod 12, thereby realizing the adjustment of the length of the first support rod 11 and the second support rod 12. The engagement of the moving block 24 and the limiting groove 25 can realize the fixation of the first support rod 11. During the movement of the first support rod 11, the sliding block 28 will slide accordingly inside the sliding groove 29;

[0033] By setting the support block 33 and the rubber block 34, the drone can be auxiliary supported. The contact between the rubber block 34 and the ground can increase the friction, making the support of the support frame more stable. By rotating the threaded rod 35 to separate the threaded rod 35 and the slot 36, the fixation of the connecting block 31 can be released, and then the connecting block 31 can be pulled out from the fixing block 3, and the entire support block 33 can be stored or replaced; by plugging the threaded rod 35 and the slot 36 together, the connecting block 31 can be fixed, so that the support block 33 can be used.

[0034] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
