Description

Technical Field

[0001] This invention relates to the field of engineering surveying instruments, specifically a portable surveying device and its usage method. Background Technology

[0002] A surveying instrument is an instrument used for data acquisition, processing, and output in surveying operations. It is mainly used in various engineering constructions for various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry tasks required in the planning, design, construction, and operation management stages. It is an indispensable device in modern engineering operations.

[0003] An existing patent (publication number: CN115363330B) discloses a portable engineering surveying device, including a surveying instrument back case and a support back case. The surveying instrument back case contains a surveying instrument, and the support back case contains a support that cooperates with the surveying instrument. Protective sleeves are provided on both sides of the surveying instrument, and opening and closing components are connected to the protective sleeves. A connecting piece is movably connected between the surveying instrument back case and the surveying instrument. The opening and closing components are fixedly connected to the connecting piece. A connecting plate is provided on the top of the support back case that connects and cooperates with the bottom of the surveying instrument, and a through hole is provided on the bottom of the support back case that slides with the support. In the process of developing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: 1. When rapid relocation is urgently needed, existing devices require disassembling and storing the support and the instrument body sequentially, which can easily waste a lot of time; 2. Secondly, when operating the instrument body, the entire instrument body needs to be removed for subsequent operations, which can easily lead to bumps and knocks during handling and placement, making it unsafe; 3. Furthermore, to cope with inclement weather such as rain, surveying devices are generally equipped with corresponding shielding devices for protection and ease of use. However, when storing and moving the equipment, the shielding device structure is too fixed, making it difficult to fold or store, thus taking up too much space during transport and making it inconvenient to use.

[0012] Both sides of the vertical plate are fixedly connected to limiting gears.

[0013] Preferably, the limiting component includes a sliding block and a limiting groove. The outer wall of the sliding block is slidably connected to the inner wall of the rotating chamber. The sliding block and the vertical plate are horizontally arranged. A trigger plate is fixedly connected to the bottom end of the sliding block.

[0014] Preferably, the release component includes a release chamber and a take-up roller. The release chamber is located in the inner wall of the handle and is connected to a sliding track. A movable column is slidably connected to one outer wall of the release chamber, and a toothed plate is fixedly connected to the front end of the movable column. The take-up roller is rotatably connected to the inner wall of the release chamber. A drive gear is fixedly connected to one side of the take-up roller, and the outer teeth of the drive gear mesh with the outer teeth of the toothed plate and are horizontally arranged. The take-up roller is connected to the drive block via a steel cable.

[0015] A method for using a portable surveying device includes the following steps:

[0016] S1. When equipment needs to be transferred or moved, the staff manually pulls the protrusion, which drives the squeezing rod to move backward in the limiting groove. At this time, the guide wheel on the shielding plate is released from the restriction. At the same time, the tension spring on the telescopic rod is used to make the entire shielding plate slide on the slide through the guide wheel, causing the shielding plate to rotate 90 degrees counterclockwise and slide downward, and then be vertically stored on the vertical plate.

[0017] S2. When the shielding plate is in a vertical position, the bottom end of the shielding plate presses the sliding block to slide in the rotating chamber. At the same time, the sliding block presses the trigger plate to move down, the trigger plate presses the telescopic spring rod to move down, and the limiting block on the trigger plate moves away from the limiting gear on the vertical plate, causing the vertical plate to be released from the restriction. At this time, the vertical plate starts to rotate by its own gravity, thereby quickly storing the shielding plate.

[0018] S3. Next, hold the handles on both sides of the storage box and press the movable column firmly. The movable column slides inward into the release chamber under force. At the same time, the toothed plate on the movable column drives the winding roller to rotate. Through the setting of the steel cable, the drive block is pulled, causing the drive block to move backward. The drive block drives the limit plate to unfold through two sets of drive rods, releasing the lock on the sliding table. At this time, you only need to manually pull the storage box to make the storage box slide between the storage box and the bracket base. Then, the staff needs to push the locking rod on the bracket base backward, so that the locking rod slides in the slot. The locking rod moves out of the slot, releasing the lock on the connecting rod. At this time, the entire bracket base can be rotated so that the sliding table and connecting rod are rotated relative to the bracket base and put into the storage slot. At the same time, through the setting of the slide and the through slot, the entire bracket base is pushed upward to store.

[0019] S4. As the bracket base slides in the first storage compartment, it pushes the push rod upward. The push rod pushes the trigger block through the transmission rod, causing the drive plate to move forward. The protrusions at both ends of the drive block press against the push plate, causing the entire fixed rod to slide through the telescopic spring.

[0020] S5. When the fixed rod moves backward in the second storage compartment, it drives the limiting plate at the other end away from the limiting groove, releasing the restriction on the transmission gear. At this time, several tooth blocks on the drive plate push the transmission gear, causing the transmission gear to drive the carrier to rotate and flip, putting the entire instrument body into the second storage compartment.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In this invention, by setting up a storage mechanism and utilizing the release element in the handle and the connecting rod in the bracket base, after the sliding table is unlocked, the entire bracket base can rotate relative to the sliding table and the connecting rod. The connecting rod is stored in the storage slot, so that the bracket base can be stored without being removed from the device. As the bracket base moves upward, the linkage can be triggered to flip the instrument body, which facilitates quick storage and reduces the operation process.

[0023] In this invention, by setting up a flipping mechanism, when the drive plate moves forward, the protruding plate on the drive plate presses against the push plate, causing the fixing rod to retract through the telescopic spring, pulling the limiting plate away from the limiting groove, and releasing the lock on the bearing seat. At this time, the toothed block meshes with the transmission gear, indirectly driving the bearing seat to rotate, and storing the instrument body into the second storage compartment, so that the staff does not need to disassemble the instrument, making it convenient and quick to store and protect.

[0024] In this invention, by setting up a shielding mechanism, when the device is in use, the operator manually pulls the protruding block, causing the squeezing rod to retract into the limiting groove. At this time, the restriction on the guide wheel is released. Through the tension spring in the telescopic rod, the shielding plate is pulled to slide in the slide rail through the guide wheel, and then the shielding plate rotates and retracts vertically. When the shielding plate is in the vertical retracted state, the bottom end of the shielding plate contacts the sliding block. The sliding block squeezes the trigger plate downward, so that the limiting blocks on both sides of the trigger plate move away from the limiting gear, causing the entire vertical plate to rotate. Thus, it is automatically rotated counterclockwise by gravity for storage, which facilitates the quick storage of the device. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The support base 3 includes a storage groove 31, which is formed on the top wall of the support base 3. A connecting rod 32 is rotatably connected to one inner wall of the storage groove 31. A sliding table 33 is fixedly connected to the top of the connecting rod 32. A slot 34 is formed in one inner wall of the connecting rod 32. A locking rod 35 is inserted into the inner wall of the slot 34. A return spring is fixedly connected to the rear end of the locking rod 35. The rear end of the return spring is fixedly connected to the inner wall of the support base 3.

[0043] The storage mechanism 4 includes a first storage compartment 41, which is located inside the storage box 1. A linkage 42 is movably arranged in the inner wall of the first storage compartment 41. A movable compartment 43 is opened at the bottom of the first storage compartment 41. A positioning plate 44 is fixedly connected to the inner wall of the movable compartment 43. A driving block 45 is slidably connected to the top of the positioning plate 44. Both ends of the driving block 45 are rotatably connected to hinge rods, and the ends of the two sets of hinge rods are rotatably connected to limiting plates 46. Insert rods are fixedly connected to the inner side walls of the two sets of limiting plates 46. A spring rod 47 is fixedly connected to the rear end of the driving block 45, and the end of the spring rod 47 is fixedly connected to the top of the positioning plate 44. A sliding track 48 is horizontally opened below the driving block 45, and the other end of the sliding track 48 is inclined upward. A through groove 49 is connected to one side of the end of the sliding track 48, and the through groove 49 is opened on the inner side wall of the first storage compartment 41.

[0044] The inner wall of the sliding track 48 is slidably connected to the outer wall of the sliding platform 33, and the sliding platform 33 is horizontally set with the two sets of limiting plates 46. With the setting of the storage mechanism 4, and the setting of the release part 8 in the handle 7 and the connecting rod 32 in the bracket base 3, after the locking of the sliding platform 33 is released, the entire bracket base 3 can rotate relative to the sliding platform 33 and the connecting rod 32, and the connecting rod 32 is stored in the storage slot 31, so that the bracket base 3 can be stored without being removed from the device. As the bracket base 3 moves upward, the linkage 42 can be triggered to flip the instrument body 2, which facilitates quick storage and reduces the operation process.

[0045] In this embodiment, as Figure 2 , Figure 4 and Figure 5As shown, the linkage compartment 421 is located within the inner wall of the first storage compartment 41. A retaining plate 422 is horizontally arranged on one side of the linkage compartment 421. The outer wall of the retaining plate 422 is slidably connected to the inner wall of the first storage compartment 41. A telescopic spring is fixedly connected to the rear wall of the retaining plate 422, and a pull rod is fixedly connected to the rear end of the retaining plate 422. A push rod 423 is slidably arranged within the inner wall of the linkage compartment 421. A compression spring is fixedly connected to the top end of the push rod 423. A transmission rod 424 is hinged to one side of the top end of the push rod 423, and a trigger block 425 is hinged to the other end of the transmission rod 424. The outer wall of the trigger block 425 is connected to the inner wall of the first storage compartment 41. The top wall of the storage compartment 41 is slidably connected, and the top of the trigger block 425 is fixedly connected to the drive plate 426. Several equally spaced toothed blocks 427 are fixedly connected to the bottom of both sides of the drive plate 426. The outer walls of both ends of the drive plate 426 are fixedly connected to the protrusions 428. As the bracket base 3 slides in the first storage compartment 41, it pushes the push rod 423 to move upward. The push rod 423 pushes the trigger block 425 through the transmission rod 424, which drives the drive plate 426 to move forward. The protrusions 676 at both ends of the drive block 45 press the push plate 58, so that the entire fixed rod 57 slides through the telescopic spring.

[0046] In this embodiment, as Figure 2 and Figure 5 As shown, the cross-section of the drive plate 426 is arranged in a U-shape. The drive plate 426 is horizontally positioned at the top of the storage box 1. The U-shape structure facilitates the drive plate 426 to simultaneously push both ends of the support plate to flip, thus ensuring stability.

[0047] In this embodiment, as Figure 1 , Figure 5 and Figure 8As shown, the flipping mechanism 5 includes a second storage compartment 51, a limiting groove 55, and a push plate 58. The second storage compartment 51 is located inside the storage box 1. A rotating groove 52 is provided on the side wall of the second storage compartment 51, and a transmission gear 53 is rotatably connected to the inner wall of the rotating groove 52. One end of the transmission gear 53 is rotatably connected to a support seat 54. The support seat 54 has an L-shaped cross-section, and its bottom wall is rotatably connected to the bottom end of the instrument body 2. The limiting groove 55 is located on one side of the groove wall of the rotating groove 52, and a limiting plate 56 is inserted into the inner wall of the limiting groove 55. A fixing rod 57 is fixedly connected to one end of the limiting plate 56. A telescopic spring is fixedly connected to the front end of the fixed rod 57, and the front end of the telescopic spring is fixedly connected to the inner wall of the second storage compartment 51. One end of the push plate 58 is fixedly connected to the outer wall of the fixed rod 57. The push plate 58 and the drive plate 426 are set horizontally. When the fixed rod 57 moves backward in the second storage compartment 51, it drives the limiting plate 56 at the other end to move away from the limiting groove 55, thereby releasing the restriction on the transmission gear 53. At this time, several tooth blocks 427 on the drive plate 426 push the transmission gear 53, causing the transmission gear 53 to drive the bearing seat 54 to rotate and flip, so that the entire instrument body 2 is put into the second storage compartment 51.

[0048] In this embodiment, as Figure 9 , Figure 10 and Figure 11 As shown, the shielding mechanism 6 includes a rotating chamber 61, a shielding plate 64, a telescopic rod 66, and a limiting member 67. The rotating chamber 61 is located at the top of the storage box 1. A vertical plate 62 is rotatably connected to the inner wall of the rotating chamber 61. Slides 63 are fixedly connected to the outer walls of both ends of the vertical plate 62. The slides 63 are inverted L-shaped structures, and a through groove is opened at one end of each of the two sets of slides 63. The shielding plate 64 is movably disposed between the two sets of through grooves, and guide wheels 65 are rotatably connected to both sides of the shielding plate 64. The guide wheels 65 are slidably connected to the slides 63. One side of the shaft end of the guide wheel 65 extends out through the through groove. The bottom end of the telescopic rod 66 is fixedly connected to the inner wall of the storage box 1, and the front end of the telescopic rod 66 is rotatably connected to the shaft end of the guide wheel 65. The fixed end and the moving end of the telescopic rod 66 are fixedly connected by a tension spring. The limiting member 67 is movably disposed inside the rotating chamber 61.

[0049] Both sides of the vertical plate 62 are fixedly connected to limiting gears. When the operator manually pulls the protrusion 676, the protrusion 676 drives the squeezing rod 675 to move backward in the limiting groove 674. At this time, the guide wheel 65 on the shielding plate 64 is released from the restriction. At the same time, with the help of the tension spring on the telescopic rod 66, the entire shielding plate 64 is subjected to force and slides on the slide rail 63 through the guide wheel 65, causing the shielding plate 64 to rotate ninety degrees counterclockwise and slide downward, and then vertically retract into the vertical plate 62.

[0050] In this embodiment, as Figure 9, Figure 10 and Figure 11 As shown, the limiting component 67 includes a sliding block 671 and a limiting groove 674. The outer wall of the sliding block 671 is slidably connected to the inner wall of the rotating chamber 61. The sliding block 671 and the vertical plate 62 are horizontally arranged. A trigger plate 672 is fixedly connected to the bottom end of the sliding block 671. Limiting blocks 673 are fixedly connected to both sides of the top edge of one side of the trigger plate 672, and the limiting blocks 673 mesh with the external teeth of the limiting gear. A telescopic spring rod 47 is fixedly fixed to the bottom end of the trigger plate 672. The limiting groove 674 is opened on the inner side wall of one side slide 63 on the vertical plate 62. A telescopic spring rod 47 is fixedly connected to the inner wall of the limiting groove 674, and the telescopic spring rod 47 is extended. A pressing rod 675 is fixedly connected to the front end of the spring rod 47. A protrusion 676 is fixed to one end of the pressing rod 675, and the protrusion 676 extends to the sliding outer wall. When the shielding plate 64 is in a vertical state, the bottom end of the shielding plate 64 presses the sliding block 671 to slide in the rotating chamber 61. At the same time, the sliding block 671 presses the trigger plate 672 to move down. The trigger plate 672 presses the telescopic spring rod 47 to move down. At the same time, the limiting block 673 on the trigger plate 672 moves away from the limiting gear on the vertical plate 62, causing the vertical plate 62 to be released from the restriction. At this time, the vertical plate 62 starts to rotate by its own gravity, thereby quickly retracting.

[0051] In this embodiment, as Figure 2 and Figure 14 As shown, the release component 8 includes a release chamber 81 and a take-up roller 84. The release chamber 81 is located in the inner wall of the handle 7 and is connected to the slide rail 48. A movable column 82 is slidably connected to one outer wall of the release chamber 81. A toothed plate 83 is fixedly connected to the front end of the movable column 82. The take-up roller 84 is rotatably connected to the inner wall of the release chamber 81. A drive gear is fixedly connected to one side of the take-up roller 84, and the outer teeth of the drive gear mesh with the outer teeth of the toothed plate 83 and are set horizontally. The take-up roller 84 is connected to the drive block 45 through a steel cable. Then, by holding the handles 7 on both sides of the storage box 1 and pressing the movable column 82, the movable column 82 slides towards the inside of the release chamber 81 under force. At the same time, the toothed plate 83 on the movable column 82 drives the take-up roller 84 to rotate. Through the setting of the steel cable, the drive block 45 is pulled, causing the drive block 45 to move backward. The drive block 45 drives the limit plate 56 to unfold through two sets of drive rods, releasing the lock on the slide table 33.

[0052] In this embodiment, as Figures 1 to 14 As shown, a method for using a portable surveying device includes the following steps:

[0053] S1. When equipment needs to be transferred or moved, the staff manually pulls the protrusion 676. The protrusion 676 drives the squeezing rod 675 to move backward in the limiting groove 674. At this time, the guide wheel 65 on the shielding plate 64 is released from the restriction. At the same time, with the help of the tension spring on the telescopic rod 66, the entire shielding plate 64 is subjected to force and slides on the slide rail 63 through the guide wheel 65, causing the shielding plate 64 to rotate ninety degrees counterclockwise and slide downward, and vertically retract into the vertical plate 62.

[0054] S2. When the shielding plate 64 is in a vertical position, the bottom end of the shielding plate 64 presses the sliding block 671 to slide in the rotating chamber 61. At the same time, the sliding block 671 presses the trigger plate 672 to move down, the trigger plate 672 presses the telescopic spring rod 47 to move down, and at the same time, the limiting block 673 on the trigger plate 672 moves away from the limiting gear on the vertical plate 62, causing the vertical plate 62 to be released from the restriction. At this time, the vertical plate 62 starts to rotate by its own gravity, thereby quickly storing it.

[0055] S3. Next, hold the handles 7 on both sides of the storage box 1 and press the movable column 82. The movable column 82 slides into the release chamber 81 under force. At the same time, the toothed plate 83 on the movable column 82 drives the winding roller 84 to rotate. Through the setting of the steel cable, the drive block 45 is pulled, causing the drive block 45 to move backward. The drive block 45 drives the limit plate 56 to unfold through the two sets of drive rods, releasing the lock on the sliding table 33. At this time, you only need to manually pull the storage box 1 to make the storage box 1 slide between the storage box 1 and the bracket base 3. Then, the staff needs to push the locking rod 35 on the bracket base 3 backward, so that the locking rod 35 slides in the slot 34. The locking rod 35 moves out of the slot 34, releasing the lock on the connecting rod 32. At this time, the entire bracket base 3 can be rotated so that the sliding table 33 and the connecting rod 32 are rotated relative to the bracket base 3 and put into the storage slot 31. At the same time, through the setting of the slide 63 and the through slot 49, the entire bracket base 3 is pushed upward for storage.

[0056] S4. As the bracket base 3 slides in the first storage compartment 41, it pushes the push rod 423 to move upward. The push rod 423 pushes the trigger block 425 through the transmission rod 424, which drives the drive plate 426 to move forward. The protrusions 676 at both ends of the drive block 45 press the push plate 58, so that the entire fixed rod 57 slides through the telescopic spring.

[0057] S5. When the fixed rod 57 moves backward in the second storage compartment 51, it drives the limiting plate 56 at the other end to move away from the limiting groove 55, releasing the restriction on the transmission gear 53. At this time, several tooth blocks 427 on the drive plate 426 push the transmission gear 53, causing the transmission gear 53 to drive the bearing seat 54 to rotate and flip, so that the entire instrument body 2 is put into the second storage compartment 51.

5. The method of using a portable surveying device according to claim 4, characterized in that: Includes the following steps: S1. When equipment needs to be moved, the staff manually pulls the protrusion block, which drives the squeezing rod to move backward in the limiting groove. At this time, the guide wheel on the shielding plate is released from the restriction. At the same time, the tension spring on the telescopic rod is used to make the entire shielding plate slide on the slide through the guide wheel, causing the shielding plate to rotate 90 degrees counterclockwise and slide downward, and then be vertically retracted into the vertical plate. S2. When the shielding plate is in a vertical position, the bottom end of the shielding plate presses the sliding block to slide in the rotating chamber. At the same time, the sliding block presses the trigger plate to move down, the trigger plate presses the telescopic spring rod to move down, and the limiting block on the trigger plate moves away from the limiting gear on the vertical plate, causing the vertical plate to be released from the restriction. At this time, the vertical plate starts to rotate by its own gravity, thereby quickly storing the shielding plate. S3. Next, hold the handles on both sides of the storage box and press the movable column firmly. The movable column slides inward into the release chamber under force. At the same time, the toothed plate on the movable column drives the winding roller to rotate. Through the setting of the steel cable, the drive block is pulled, causing the drive block to move backward. The drive block drives the limiting plate to unfold through two hinge rods, releasing the lock on the sliding table. At this time, you only need to manually pull the storage box to make the storage box slide between the storage box and the bracket base. Then, the staff needs to push the locking rod on the bracket base backward, so that the locking rod slides in the slot. The locking rod moves out of the slot, releasing the lock on the connecting rod. At this time, the entire bracket base can be rotated, so that the sliding table and the connecting rod rotate relative to the bracket base and are put into the storage slot. At the same time, through the setting of the sliding track and the through slot, the entire bracket base is pushed upward to store. S4. As the bracket base slides in the first storage compartment, it pushes the push rod upward. The push rod pushes the trigger block through the transmission rod, causing the drive plate to move forward. The protruding plates at both ends of the drive plate press against the push plate, causing the entire fixed rod to slide through the telescopic spring. S5. When the fixed rod moves backward in the second storage compartment, it drives the limiting plate at the other end away from the limiting groove, releasing the restriction on the transmission gear. At this time, several tooth blocks on the drive plate push the transmission gear, causing the transmission gear to drive the carrier to rotate and flip, putting the entire instrument body into the second storage compartment.
