[0020] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4The present invention provides a technical solution: a box-type portable surveying tripod, comprising a main base 1, side bases 2 are arranged on both sides of the rear end of the main base 1, a hinge 3 is arranged between the rear ends of the two side bases 2, the hinge 3 is a mature existing technology, the main base 1 and the side base 2 are rotatably connected by the hinge 3, the bottom of the main base 1 and the two side bases 2 are arranged with a leg assembly 4, a small rod 5 is fixedly connected inside the hinge 3, a folding assembly 6 is arranged at the front end of the hinge 3, the folding assembly 6 includes a motor 61 fixedly connected to the front end of the main base 1, and the main base 1 is installed with a motor 61 connected to the motor 61 An electrically connected storage battery is used to power the motor 61. The output shaft of the motor 61 extends into the interior of the main base 1 and is fixedly connected to a rotating rod 62. The rear end of the rotating rod 62 is rotatably connected to the inner rear portion of the main base 1. The rear end of the outer wall of the rotating rod 62 is fixedly connected to a gear 63. The folding component 6 also includes a rack 64 slidably connected to the top and bottom ends of the inner rear portion of the main base 1. The two racks 64 are meshed with the gear 63 on one side close to the gear 63. The two racks 64 are fixedly connected to one end of the side close to the side base 2 on the side away from each other with a connecting rod 65. The connecting rod 65 is rotatably connected to the side base 2 on the side close to the side base 2.

[0022] By adopting the above technical scheme, when the surveying and mapping tripod needs to be folded, the output shaft of the motor 61 drives the rotating rod 62 to rotate, thereby causing the gear 63 to rotate. At this time, under the action of the meshing of the two racks 64 and the gear 63, the two racks 64 can be moved in a direction close to each other, so that the connecting rod 65 moves with the rotating connection between the connecting rod 65 and the side base 2. During this process, the two side bases 2 can be rotated inward around the axis of the hinge 3, so that the adjacent sides of the two side bases 2 are close and fit together, so that the two side bases 2 and the main base 1 are folded into a rectangular box shape. When the tripod is transported, the folded rectangular box shape is not easy to roll and fall when it is folded and placed, so that the tripod is not easy to be damaged in the trunk during vehicle transportation, and multiple tripods can be stacked and not easy to roll, which is convenient for operators to carry.

[0023] When the tripod needs to be unfolded to install the surveying instrument, the output shaft of the motor 61 moves in the opposite direction to the previous direction, so that the two racks 64 move away from each other, thereby causing the connecting rod 65 to move with the rotating connection between the connecting rod 65 and the side base 2. During this process, the two side bases 2 can be rotated outward around the axis of the hinge 3, so that the two side bases 2 are moved away from each other, and the two side bases 2 and the main base 1 are unfolded into a triangle shape, and the leg assembly 4 is partially unfolded to support the two side bases 2 and part of the main base 1.

[0024] It should be noted that a slot hole adapted to the connecting rod 65 is provided at the rear end of the main base 1 to facilitate the sliding of the connecting rod 65 .

[0025] Specifically, Figures 1 to 4 As shown, the outer wall of the small rod 5 is rotatably connected to a frame 10, and an intermediate tightening screw 11 for installing a surveying instrument is provided inside the frame 10. The top of the side where the two side bases 2 are close to each other is provided with a recessed groove 16 adapted to the frame 10 and the intermediate tightening screw 11.

[0026] By adopting the above technical solution, the middle tightening screw 11 is used to install the surveying instrument. When the tripod is folded, the frame 10 and the middle tightening screw 11 can just enter the interior of the groove 16. This design can ensure that the frame 10 and the middle tightening screw 11 do not affect the folding between the two side bases 2 and the main base 1.

[0027] Specifically, Figure 1 and Figures 5 to 8 As shown, the bottom of the main base 1 and the two side bases 2 are provided with a groove 15, the interior of the groove 15 is rotatably connected to the rotating rod 14, the leg assembly 4 includes a cover 41 fixedly connected to the outer wall of the rotating rod 14, the interior of the cover 41 is slidably connected to the sliding leg 42, the interior of the sliding leg 42 is slidably connected to the bottom leg 43, the bottom of the bottom leg 43 is fixedly connected to the needle 44, the bottom of the outer wall of the bottom leg 43 is rotatably connected to the pedal 45, the outer side of the sliding leg 42 is provided with a slot 46 adapted to the pedal 45, and the outer wall of the bottom leg 43 is located above the pedal 45 and is fixedly connected A first magnetic block 47, a latch hole 48 is provided on the top of the side of the sliding leg 42, a first bolt 49 is threadedly connected to the top of the cover 41 at a position corresponding to the latch hole 48, a hidden hole is provided around the latch hole 48, and the first bolt 49 can be hidden inside it, a recessed hole 410 is provided on the top of the inner side of the bottom leg 43, a second bolt 411 is threadedly connected to the inner side of the sliding leg 42 at a position corresponding to the recessed hole 410, a hidden hole is also provided around the recessed hole 410, and the second bolt 411 can be hidden inside it, so that the overall device is neat and unobtrusive, and the top of the sliding leg 42 is fixedly connected to the second magnetic block 412.

[0028] By adopting the above technical solution, part of the entire leg assembly 4 can be rotated around the rotating rod 14. When the leg assembly 4 is unfolded, the sliding leg 42 is slid downward inside the cover 41, and the bottom leg 43 is slid downward inside the sliding leg 42. At this time, the end of the first bolt 49 is just aligned with the clamping hole 48, and the first bolt 49 can be inserted into the inside of the clamping hole 48 by rotating the first bolt 49. At this time, the end of the second bolt 411 is just aligned with the recessed hole 410, and the second bolt 411 can be inserted into the inside of the recessed hole 410 by rotating the second bolt 411, thereby completing the unfolding of the leg assembly 4 part, and the bottom of the needle 44 can be inserted into the soil, so as to support the main base 1 and the two side bases 2.

[0029] When part of the leg assembly 4 needs to be folded, the bottom leg 43 is moved to an upward position, and then the pedal 45 can be manually flipped over so that the pedal 45 can be just hidden in the slot 46. The pedal 45 can be made of iron material, and under the magnetic force of the first magnetic block 47, the first magnetic block 47 can adsorb the pedal 45. At this time, the slot 46 limits the pedal 45, and the bottom leg 43 and the sliding leg 42 cannot slide relative to each other. When unfolding, flipping the pedal 45 to keep it away from the slot 46 can make the bottom leg 43 be pulled downward.

[0030] When part of the leg assembly 4 is folded, the sliding leg 42 needs to be slid upward manually. The material on the inner side of the bottom of the cover 41 can also be made of iron material. Under the magnetic force of the second magnetic block 412, the movement between the sliding leg 42 and the cover 41 can be limited to a certain extent. When unfolding, the sliding leg 42 can be pulled forcefully to make the sliding leg 42 slide.

[0031] Specifically, Figures 1 to 8As shown, the main base 1 and the side base 2 are both provided with a locking assembly 7, and the locking assembly 7 includes a fixed cover 71 fixedly connected to the main base 1 and the two side bases 2 respectively, a circular hole 72 is opened inside the fixed cover 71, and a piston plate 73 is movably connected inside the circular hole 72, a guide tube 74 is fixedly inserted inside the circular hole 72, and an elastic capsule 75 is fixedly inserted at one end of the guide tube 74 away from the fixed cover 71, and a hole groove 76 is opened near the groove 15 of the main base 1 and the two side bases 2, and the elastic capsule 75 is located inside the hole groove 76, and a movable plate 77 is slidably connected inside the hole groove 76, and a plug rod 78 is fixedly connected to the side of the movable plate 77 away from the elastic capsule 75, and a limiting hole 17 is opened at the top of the cover 41 at a position on one side of the plug rod 78, and a first trigger assembly 8 is arranged inside the main base 1, and the two side bases 2 are both provided with There is a second trigger component 9, the interior of the limiting hole 17 is tilted, the first trigger component 8 includes a lifting plate 81 slidably connected to the rear end of the main base 1, the bottom of the lifting plate 81 is fixedly connected to a connecting frame 82, the bottom of the connecting frame 82 is fixedly connected to the piston plate 73 located inside the main base 1, a first spring 83 is fixedly connected between the bottom of the lifting plate 81 and the fixed cover 71 located inside the main base 1, the right side of the rack 64 at the upper end and the top of the lifting plate 81 are both tilted, the second trigger component 9 includes a moving frame 91 slidably connected to the inside of the two side bases 2 near the hidden groove 16, the side of the moving frame 91 away from the frame 10 is fixedly connected to the piston plate 73 located inside the side base 2, a second spring 92 is fixedly connected between the moving frame 91 and the side base 2, the inclined design of the limiting hole 17 is conducive to the insertion of the insertion rod 78 into the limiting hole 17.

[0032] By adopting the above technical solution, when folding, first fold part of the leg assembly 4, try to make the top surface of the main base 1 and the side base 2 in a horizontal state, under the action of gravity, the position of the cover 41 is in a relatively vertical state, which is convenient for the insertion rod 78 to align with the limit hole 17, and then the output shaft of the motor 61 rotates so that the two side bases 2 are folded and closed. During this process, the rack 64 at the top will move to the right direction, and the right inclined part of the rack 64 at the top will squeeze the top surface of the lifting plate 81, so that the lifting plate 81 can move downward, and the first spring 83 is in a compressed state. At this time, To control the connection frame 82 to move downward, so that the connection frame 82 moves with the piston plate 73 inside the main base 1, so that the piston plate 73 slides inside the circular hole 72 inside the fixed cover 71, and the piston plate 73 pushes the air inside the circular hole 72 into the inside of the conduit 74, and then the gas enters the inside of the elastic bag 75 in the main base 1, so that the inside of the elastic bag 75 expands, and at this time the elastic bag 75 squeezes the movable plate 77 and the insertion rod 78 in the main base 1, so that the movable plate 77 and the insertion rod 78 slide inside the hole groove 76, so that the end of the insertion rod 78 is inserted into the inside of the limiting hole 17.

[0033] It should be noted that the top width of the lifting plate 81 is greater than the width of the tooth groove formed by the rack 64 .

[0034] When unfolded, the upper rack 64 moves to the left to reset. Under the elastic force of the first spring 83 itself, the lifting plate 81, the connecting frame 82 and the piston plate 73 inside the main base 1 are reset. At this time, the gas inside the elastic bag 75 is reduced, and the elastic bag 75 contracts, so that the moving plate 77 and the insertion rod 78 are reset.

[0035] When the two side bases 2 are folded and closed, the frame 10 and the middle tightening screw 11 just enter the interior of the hidden groove 16. At this time, the frame 10 squeezes the movable frame 91, and the second spring 92 is in a compressed state. At this time, the movable frame 91 moves with the piston plate 73 inside the side base 2, so that the piston plate 73 pushes the air inside the circular hole 72 inside the side base 2 into the interior of the conduit 74, and then the gas enters the interior of the elastic bag 75 in the side base 2, so that the interior of the elastic bag 75 expands. At this time, the elastic bag 75 squeezes the movable plate 77 and the insertion rod 78 in the main base 1 so that the movable plate 77 and the insertion rod 78 can slide inside the hole groove 76, so that the end of the insertion rod 78 is inserted into the interior of the limiting hole 17.

[0036] When unfolded, the two side bases 2 move away from each other. Under the elastic force of the second spring 92, the movable frame 91 brings the piston plate 73 inside the side base 2 to reset. At this time, the internal gas of the elastic bag 75 in the side base 2 is reduced, and the elastic bag 75 contracts, so that the movable plate 77 and the insertion rod 78 are reset.

[0037] Such a design enables the leg assembly 4 to be automatically limited when the tripod is folded, so that the leg parts of the tripod do not need to be additionally tied and fixed when folded for transportation.

[0038] Specifically, Figures 5 and 6 As shown, a limiting groove 18 is provided at the top of the sleeve 41, an elastic membrane 19 is fixedly connected inside the limiting groove 18, a limiting rod 20 is fixedly connected inside the elastic membrane 19, an outer wall of the limiting rod 20 is slidably connected to the sleeve 41, a small frame 13 is slidably connected inside the limiting hole 17, and a connecting plate 12 is fixedly connected between the small frame 13 and the limiting rod 20.

[0039] By adopting the above technical solution, when the second magnetic block 412 attracts the inner top of the cover 41, the limiting rod 20 is aligned with the card hole 48, and in the initial state, under the elastic force of the elastic membrane 19, the end of the limiting rod 20 does not extend from the inside of the cover 41. When folding, since the insertion rod 78 is inserted into the inside of the limiting hole 17, during this process, the insertion rod 78 pressurizes the small frame 13, so that the small frame 13 moves toward the card hole 48 with the connecting plate 12 and the limiting rod 20, so that the limiting rod 20 is inserted into the card hole 48, thereby further limiting the movement between the sliding leg 42 and the cover 41.

[0040] Working principle: When the surveying tripod needs to be folded, the output shaft of the motor 61 drives the rotating rod 62 to rotate, thereby rotating the gear 63. At this time, under the action of the meshing of the two racks 64 and the gear 63, the two racks 64 can be moved in a direction close to each other, so that the connecting rod 65 moves with the connecting rod 65 and the side base 2. In this process, the two side bases 2 can be rotated inward around the axis of the hinge 3, so that the adjacent sides of the two side bases 2 are close to each other and fit together, so that the two side bases 2 and the main base 1 are folded into A rectangular box shape. When the tripod needs to be unfolded to install the surveying instrument, the output shaft of the motor 61 moves in the opposite direction to the previous direction, so that the two racks 64 move away from each other, so that the connecting rod 65 moves with the rotating connection between the connecting rod 65 and the side base 2. During this process, the two side bases 2 can be rotated outward around the axis of the hinge 3, so that the two side bases 2 are separated from each other, so that the two side bases 2 and the main base 1 are unfolded into a triangle, and the leg assembly 4 is partially unfolded to support the two side bases 2 and part of the main base 1.

[0041] When the leg assembly 4 is unfolded, the sliding leg 42 is slid downward inside the cover 41, and the bottom leg 43 is slid downward inside the sliding leg 42. At this time, the end of the first bolt 49 is just aligned with the clamping hole 48, and the first bolt 49 can be inserted into the inside of the clamping hole 48 by rotating the first bolt 49. At this time, the end of the second bolt 411 is just aligned with the concave hole 410, and the second bolt 411 can be inserted into the inside of the concave hole 410 by rotating the second bolt 411, thereby completing the partial unfolding of the leg assembly 4, and the bottom of the needle 44 can be inserted into the soil, so as to support the main base 1 and the two side bases 2. When the leg assembly 4 is partially folded, By moving the bottom leg 43 to an upward position, the pedal 45 can be manually flipped over so that the pedal 45 can be just hidden in the interior of the card slot 46. The pedal 45 can be made of iron material. Under the magnetic force of the first magnetic block 47, the first magnetic block 47 can adsorb the pedal 45. At this time, the card slot 46 limits the pedal 45, and the bottom leg 43 and the sliding leg 42 cannot slide relative to each other. When unfolding, flipping the pedal 45 to keep the pedal 45 away from the card slot 46 can make the bottom leg 43 pulled downward. When the tripod is folded, part of the leg assembly 4 can be automatically limited, so that when folded for transportation, there is no need to additionally tie and fix the leg part of the tripod.
