[0006] Furthermore, the connecting block, guide rod, support block, mounting base block, helical spring, and cleaning block together form a buffer structure. A connecting block is also fixed to the bottom of the outer shell by a screw. Two guide rods slide on the connecting block. The front end of each guide rod is welded to a support block, and the rear end of each guide rod is welded to a mounting base block. A helical spring is sleeved on each guide rod. The front end of the helical spring contacts the rear end face of the connecting block, and the rear end of the helical spring contacts the front end face of the support block. The helical spring is a rearward reset component for the guide rod. A heat dissipation groove is provided on the rear end face of the outer shell.
[0007] Furthermore, a cover plate is rotatably mounted on the outer casing, and an observation window is fixed on the cover plate. The observation window is aligned with the display screen on the handheld surveying instrument. A second button is installed on the handheld surveying instrument, and a first button is installed on the outer casing. The first button is in contact with the second button.
[0008] Furthermore, a side buffer block is attached to the inner wall of the outer shell, and a front buffer block is attached to the rear end face of the cover plate. The side buffer block contacts the side of the handheld surveying instrument, and the front buffer block contacts the front end face of the handheld surveying instrument. Both the side buffer block and the front buffer block are made of rubber.
[0009] Furthermore, a power-connecting metal block A is fixed to the right end face of the inner wall of the outer shell, and a power-connecting metal block B is fixed to the right end face of the handheld surveyor. The power-connecting metal block B is electrically connected to the battery inside the handheld surveyor. A charging port is provided on the left end face of the handheld surveyor. A U-shaped contact seat is fused to the left end face of the inner wall of the outer shell. The contact seat passes through the outer shell and is aligned with the charging port. A sealing cover for sealing the contact seat is hinged to the left end face of the outer shell via a hinge.
[0010] Furthermore, a fan is fixed to both the left and right end faces of the inner wall of the outer casing. Both fans are electrically connected to the electrically connected metal block A, and both fans are electrically connected to the microprocessor inside the handheld surveying instrument.
[0011] Furthermore, the bottom end face of the outer shell has two circular mounting holes symmetrically opened, each mounting hole has a filter box fixed inside, the filter box is filled with desiccant, and the bottom end face of the outer shell has two filter screens fixed, the two filter screens are aligned with the two mounting holes.
[0012] Furthermore, a temperature sensor is installed on the top of the handheld surveying device, and the temperature sensor is electrically connected to the microprocessor inside the handheld surveying device. The microprocessor inside the handheld surveying device is equipped with a threshold value.
[0013] Furthermore, an auxiliary structure is installed on the outer shell. The auxiliary structure consists of a rotating shaft, a sliding seat, clamping blocks, an adjusting rod, a worm gear, and a worm. The rotating shaft rotates on the right end face of the outer shell. A sliding seat is welded to one end of the rotating shaft. Two clamping blocks slide on the sliding seat. An adjusting rod rotates on the sliding seat. The upper end and the lower end of the adjusting rod are threaded to the two clamping blocks, respectively. The thread directions of the upper end and the lower end of the adjusting rod are opposite.
[0014] Furthermore, a worm gear is welded onto the rotating shaft, and a worm rotates on the outer casing, meshing with the worm gear.
[0015] This invention provides a real estate surveying and mapping device with an auxiliary system, which has the following beneficial effects: In terms of protection and cleaning, the protective window on the top of the outer casing is precisely aligned with the measuring laser end of the handheld measuring instrument, ensuring smooth laser measurement while preventing the measuring end from being directly exposed. The buffer structure, composed of connecting blocks, guide rods, and other components, allows the guide rod to automatically move the cleaning block forward when the outer casing is placed on the table, thanks to the weight of the outer casing and the handheld measuring instrument. This cleans the protective window, ensuring that the laser path is not interfered with by dirt during the measurement process. At the same time, the support block supports the outer casing by contacting the table, preventing the bottom from contacting the table. This makes it easy to pick up and reduces wear and contamination on the bottom of the outer casing.
[0016] In terms of heat dissipation and dust prevention design, the heat dissipation grooves on the rear face of the outer casing provide a natural heat dissipation channel for the internal equipment. Combined with the fans on both sides of the inner wall, under the control of the microprocessor, when the temperature sensor detects a high device temperature, the fans automatically start, accelerating internal air circulation and quickly reducing the device temperature, ensuring stable operation of the surveying instrument for extended periods. The contact socket on the left side aligns with the charging port, and is fitted with a sealable cover, facilitating plug insertion during charging and providing dust protection when not charging. The design of the power connection metal block ensures stable power supply to the fan.
[0017] This application features comprehensive and reliable buffer protection. The same buffer structure is set at the top and bottom of the outer casing. When the device is accidentally dropped or impacted, the elasticity of the helical spring can effectively absorb the impact force and reduce the vibration impact on the internal handheld surveying instrument. In addition, the side buffer blocks on the inner wall of the outer casing and the front buffer block at the rear end of the cover are made of rubber, which contact the side and front face of the handheld surveying instrument respectively. They further buffer external forces through elastic deformation, protecting the surveying instrument from damage in all directions and extending the service life of the equipment.
[0018] This application utilizes an auxiliary structure where the clamping block can quickly clamp the mounting frame via a rotating adjusting rod, achieving a stable connection between the device and the external support and meeting the fixing requirements in various scenarios. During angle adjustment, the meshing transmission of the worm gear and worm wheel enables precise adjustment of the surveying angle, resulting in effortless operation and stable positioning, thus improving the flexibility and accuracy of measurement work.
[0019] In terms of ease of operation and observation, this application features a cover plate rotatably connected to the outer casing, equipped with an observation window that aligns with the surveyor's display screen, allowing users to view measurement data at any time without frequently opening the cover plate. Simultaneously, the first button on the outer casing corresponds to the second button on the surveyor, allowing indirect operation of the surveyor by pressing the first button, simplifying the operation process and avoiding wear caused by direct contact with the surveyor's buttons.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.
[0025] Example 1: Please refer to Figures 1 to 9 : This invention proposes a real estate surveying and mapping device with an auxiliary system, comprising: an outer casing 1; a handheld surveying instrument 2 is placed inside the outer casing 1, a measuring laser end 202 is mounted on the top of the handheld surveying instrument 2, a protective window 110 is fixed on the top of the outer casing 1, the protective window 110 is aligned with the measuring laser end 202; a connecting block 401 is fixed on the top of the outer casing 1 by a screw, two guide rods 402 slide on the connecting block 401, the rear end of each guide rod 402 is welded to a support block 403, the front end of each guide rod 402 is welded to a mounting base block 404, and a helical spring 405 is sleeved on each guide rod 402, the front end of the helical spring 405 being connected to the connecting block 403. 1. The rear end of the helical spring 405 contacts the front end of the support block 403. The helical spring 405 is the rearward reset component of the guide rod 402. A cleaning block 406 is attached to the bottom end of the mounting base block 404. The bottom end of the cleaning block 406 contacts the top of the outer shell 1. When the cleaning block 406 moves forward, it contacts the protective window 110. When the outer shell 1 is placed on the table, the support block 403 contacts the table. Under the gravity of the outer shell 1 and the handheld surveying instrument 2, the guide rod 402 and the cleaning block 406 move forward. At this time, the cleaning of the protective window 110 is automatically completed by the cleaning block 406. The bottom end of the outer shell 1 does not contact the table due to the support of the support block 403, which makes it convenient to pick up the device.
[0026] The connecting block 401, guide rod 402, support block 403, mounting base block 404, helical spring 405, and cleaning block 406 together form the buffer structure 4. The bottom of the outer shell 1 is also fixed with a connecting block 401 by a screw. Two guide rods 402 slide on the connecting block 401. The front end of each guide rod 402 is welded to a support block 403, and the rear end of each guide rod 402 is welded to a mounting base block 404. Each guide rod 402 is fitted with a helical spring 405. The front end of the helical spring 405 contacts the rear end face of the connecting block 401, and the rear end of the helical spring 405 contacts the front end face of the support block 403. The helical spring 405 is a rearward reset component of the guide rod 402. A heat dissipation groove 109 is provided on the rear end face of the outer shell 1. During use, the heat dissipation groove 109 can realize auxiliary heat dissipation of the handheld surveying instrument 2.
[0027] The outer casing 1 has a cover plate 101 that rotates on it. An observation window 102 is fixed on the cover plate 101. The observation window 102 is aligned with the display screen on the handheld surveyor 2. The handheld surveyor 2 is equipped with a second button 201. The outer casing 1 is equipped with a first button 103. The first button 103 is in contact with the second button 201. When in use, pressing the first button 103 will press the second button 201.
[0028] The inner wall of the outer casing 1 is attached with a side buffer block 104, and the rear end face of the cover plate 101 is attached with a front buffer block 105. The side buffer block 104 contacts the side of the handheld surveying instrument 2, and the front buffer block 105 contacts the front end face of the handheld surveying instrument 2. Both the side buffer block 104 and the front buffer block 105 are made of rubber. When the device is accidentally dropped, the side buffer block 104 and the front buffer block 105 can provide buffer protection for the handheld surveying instrument 2.
[0029] The outer casing 1 has a power-connecting metal block A106 fixed on the right end face of its inner wall, and a power-connecting metal block B203 fixed on the right end face of the handheld surveyor 2. The power-connecting metal block B203 is electrically connected to the battery inside the handheld surveyor 2. The left end face of the handheld surveyor 2 is provided with a charging socket. A U-shaped contact seat 107 is fused to the left end face of the inner wall of the outer casing 1. The contact seat 107 passes through the outer casing 1 and is aligned with the charging socket. A sealing cover 108 for sealing the contact seat 107 is hinged to the left end face of the outer casing 1. When charging, the sealing cover 108 is opened, and the charging plug is passed through the contact seat 107 and inserted into the charging socket for charging. The sealing cover 108 achieves dust prevention inside the outer casing 1.
[0030] Among them, a fan 3 is fixed on the left end face and the right end face of the inner wall of the outer shell 1. Both fans 3 are electrically connected to the electrically connected metal block A106. The two fans 3 are electrically connected to the microprocessor inside the handheld surveying instrument 2. When the handheld surveying instrument 2 is cooled, the two fans 3 are started by the microprocessor inside the handheld surveying instrument 2. The wind force generated by the rotation of the two fans 3 can cool the handheld surveying instrument 2.
[0031] The handheld surveyor 2 is equipped with a temperature sensor 204 on its top. The temperature sensor 204 is electrically connected to the microprocessor inside the handheld surveyor 2. The microprocessor inside the handheld surveyor 2 has a threshold set. During use, the temperature sensor 204 transmits temperature parameters to the microprocessor in real time. When the parameter is lower than the threshold in the microprocessor, the microprocessor drives the two fans 3 to rotate. When the parameter is higher than the threshold in the microprocessor, the microprocessor disconnects the power supply to the two fans 3, thus realizing real-time heat dissipation of the handheld surveyor 2.
[0032] The outer shell 1 is equipped with an auxiliary structure 5, which consists of a rotating shaft 501, a sliding seat 502, a clamping block 503, an adjusting rod 504, a worm gear 505, and a worm 506. The rotating shaft 501 rotates on the right end face of the outer shell 1. The sliding seat 502 is welded to one end of the right side of the rotating shaft 501. Two clamping blocks 503 slide on the sliding seat 502. An adjusting rod 504 rotates on the sliding seat 502. The upper end and the lower end of the adjusting rod 504 are threaded to the two clamping blocks 503 respectively. The threads of the upper end and the lower end of the adjusting rod 504 are in opposite directions.
[0033] The device has a worm gear 505 welded onto the rotating shaft 501 and a worm 506 rotating on the outer casing 1. The worm 506 meshes with the worm gear 505. When the device is fixed to the mounting frame, two clamping blocks 503 are snapped onto the outside of the mounting frame. The adjusting rod 504 is rotated, and the two clamping blocks 503 clamp the mounting frame under the thread drive of the adjusting rod 504. When adjusting the surveying angle, the worm 506 is rotated, and the surveying angle can be adjusted under the meshing transmission of the worm 506 and the worm gear 505.
[0034] Example 2, based on Example 1, such as Figures 1-9 As shown, two circular mounting holes 111 are symmetrically opened on the bottom end face of the outer casing 1. A filter box 112 is fixed in each mounting hole 111. The filter box 112 is filled with desiccant. Two filter screens 113 are fixed on the bottom end face of the outer casing 1. The two filter screens 113 are aligned with the two mounting holes 111. During use, when external gas enters the interior of the outer casing 1, it needs to pass through the filter screens 113 and the filter boxes 112. The filtration by the filter screens 113 and the filter boxes 112 prevents dusty and humid gas from entering the interior of the outer casing 1.
[0035] The working principle of this embodiment is as follows: During surveying, the outer casing 1 is held by hand for surveying. After surveying, when the device is placed on a table, the support block 403 contacts the table. Under the gravity of the outer casing 1 and the handheld surveyor 2, the guide rod 402 and the cleaning block 406 move forward. At this time, the cleaning block 406 automatically cleans the protective window 110. When the device is accidentally dropped, the side buffer block 104 and the front buffer block 105 can provide buffer protection for the handheld surveyor 2. When the device is fixed on the mounting frame, the two clamping blocks 503 are snapped onto the outside of the mounting frame. Rotating the adjusting rod 504 will cause the two clamping blocks 503 to move under the threaded drive of the adjusting rod 504. 3. After clamping the mounting bracket, when adjusting the surveying angle, rotate the worm gear 506. The surveying angle can be adjusted through the meshing transmission of the worm gear 506 and the worm wheel 505. When charging, open the sealing cover 108, pass the charging plug through the contact seat 107 and insert it into the charging socket for charging. After charging is completed, unplug the charging plug and close the sealing cover 108. During use, the temperature sensor 204 transmits temperature parameters to the microprocessor in real time. When the parameter is lower than the threshold in the microprocessor, the microprocessor drives the two fans 3 to rotate. When the parameter is higher than the threshold in the microprocessor, the microprocessor disconnects the power supply to the two fans 3, realizing real-time heat dissipation of the handheld surveying instrument 2.
