Description

Technical Field

[0001] This utility model relates to the field of real estate surveying instruments, and in particular to a handheld real estate surveying instrument. Background Technology

[0002] Real estate refers to things that cannot be moved by their natural nature, or whose economic value would be impaired if moved. It mainly includes land, sea areas, and fixed structures on the land, such as engineering buildings. In order to collect data on the geographical location of real estate so as to make full and reasonable use of the space of real estate, surveying instruments are often used to measure real estate.

[0003] Chinese utility model patent CN219455096U discloses a handheld quality inspection mapping instrument, including a mapping instrument body. The mapping instrument body is equipped with a display screen and buttons. A mounting box is fixedly installed on the back of the mapping instrument body. Threaded rods are rotatably installed on both sides of the mounting box. The two threaded rods are symmetrically arranged. A drive assembly for driving the two threaded rods to rotate is provided inside the mounting box. A sleeve is threadedly installed on the end of the threaded rod away from the mounting box. A protective plate for protecting the display screen is fixedly installed on the end of the sleeve away from the threaded rod. The two protective plates are symmetrically arranged and cooperate with the mapping instrument body. Locking assemblies are provided on both sides of the mapping instrument body. A protective plate for protecting the buttons is rotatably installed on the bottom of the mapping instrument body. A first locking block for cooperating with the locking assembly is fixedly installed on the protective plate.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: When using the handheld quality inspection plotter, it is necessary to drive the worm gear to rotate via a handwheel. The rotation of the worm gear drives the worm wheel and the rotating shaft to rotate. The rotation of the rotating shaft drives the threaded rods on both sides to rotate synchronously. The rotation of the threaded rods, in conjunction with the telescopic rod, drives the sleeve and the protective plate to move until the two protective plates are far apart. Then, the pull rod is pulled to separate the second locking block from the first locking block, releasing the lock on the first locking block, so that the protective plate can be opened. Only then can the measurement work be carried out through the display screen and buttons. The whole process requires opening the protective plate and the protective plate separately, which is quite cumbersome. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a handheld real estate surveying instrument.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a handheld real estate surveying instrument, including a surveying instrument body and buttons and a display screen disposed on the surveying instrument body. The surveying instrument body is provided with a baffle for simultaneously protecting the buttons and the display screen. A pair of mounting shells are fixed to the bottom of the surveying instrument body. A connecting plate rotatably disposed between the two mounting shells is fixed to the bottom of the baffle. A rotating shaft is fixed on the side wall of both sides of the connecting plate. The rotating shaft passes through the side wall of one side of the mounting shell and is rotatably connected. The surveying instrument body is provided with a locking mechanism for fixing when the baffle is used for protection.

[0007] By adopting the above technical solution, when using a real estate surveying instrument for surveying work, the operator needs to adjust the locking mechanism to release the baffle, and then rotate the baffle around the axis away from the surveying instrument body until the buttons and display screen are fully exposed. The operator can then operate the display screen and buttons on the surveying instrument body to perform measurement work. After the surveying work is completed, the operator needs to replace the baffle and use the locking mechanism to keep it fixed. The baffle provides good protection for the display screen and buttons, changing the structure of traditional technology, simplifying the operation steps, and improving efficiency.

[0008] Furthermore, the locking mechanism includes a locking assembly, which includes a mounting block fixed to the side wall of the surveying instrument body, a connecting block fixed to the side wall of the baffle at a position corresponding to the mounting block, a positioning block fixed to the side wall of the connecting block near the mounting block, and a locking plate slidably disposed on the side wall of the mounting block away from the connecting block. The top of the mounting block has a slot for inserting and cooperating with the positioning block, and the bottom of the positioning block has a positioning groove for sliding and cooperating with the locking plate. The locking mechanism also includes a support assembly for ensuring that the locking plate and the positioning groove remain in an inserted state.

[0009] By adopting the above technical solution, the operator pulls the card away from the positioning groove until the card separates from the positioning groove, then the baffle can be easily opened and the surveying instrument body can be used. After using the surveying instrument body, the baffle is rotated in the opposite direction and reset. At this time, the card is pushed upward and inserted into the positioning groove at the bottom of the positioning block to fix the baffle, so that the baffle protects the buttons and the display screen.

[0010] Furthermore, a sliding groove is provided on the side wall of the mounting block near the card plate, and the support assembly includes a slider fixed to the side wall of the card plate near the mounting block and slidingly engaged with the sliding groove, and a support spring fixed between the bottom of the slider and the bottom wall of the sliding groove.

[0011] By adopting the above technical solution, during the downward movement of the clamping plate, the slider connected to the clamping plate will slide downward along the inside of the slide groove, thereby compressing the support spring fixed to the slide groove and the slider until the clamping plate separates from the positioning groove, thus releasing the lock on the baffle and allowing it to be opened. After using the surveying instrument body, the operator first needs to push the clamping plate to the lowest position, then push the baffle to drive the connecting block and positioning block to reset. The positioning block enters the clamping groove, and finally the clamping plate is released. The clamping plate resets under the action of the support spring at the bottom of the slider and re-engages with the positioning groove at the bottom of the positioning block, thus fixing the baffle and allowing it to perform its normal protective function.

[0012] Furthermore, the mounting housing is provided with an auxiliary component for automatically opening the baffle. The auxiliary component includes a limiting plate fixedly sleeved on the rotating shaft and located inside the mounting housing, and a torsion spring sleeved on the rotating shaft and fixed between the side wall of the limiting plate and the inner wall of the mounting housing. When the torsion spring is in its original length state, the baffle is in a fully open state.

[0013] By adopting the above technical solution, when the staff releases the baffle, the torsion spring has a good torsional force, which causes the limiting plate connected to the torsion spring, the rotating shaft fixed to the limiting plate, the connecting plate fixed to the rotating shaft, and the baffle fixed to the connecting plate to rotate until the torsion spring is in its original length state, and the baffle is in the fully open state.

[0014] Furthermore, a guide rod with a clearance fit is fixed between the top wall and the bottom wall of the groove, and the support spring is sleeved on the guide rod.

[0015] By adopting the above technical solution and setting the guide rod, the stability of the slider movement is improved.

[0016] Furthermore, a fixing block is fixed on the side wall of the card plate away from the mounting block, and a wavy groove is provided on the side wall of the fixing block away from the card plate.

[0017] By adopting the above technical solution, the wavy groove and fixing block design reduce the probability of slippage for workers when pushing the pallet.

[0018] Furthermore, an inclined surface is provided at the intersection of the side wall of the positioning block away from the connecting block and the bottom of the positioning block, the distance between the inclined surface of the positioning block and the connecting block gradually decreases from top to bottom, and the top of the card plate is an upwardly convex arc shape.

[0019] By adopting the above technical solution, during the closing process of the baffle, the inclined surface on the positioning block contacts the arc surface on the top of the clamping plate, thereby causing the positioning block to press the clamping plate downwards. The support spring is subjected to force and compressed until the positioning groove is in the corresponding position of the clamping plate. Then, the support spring resets and drives the clamping plate to reset through the slider. The clamping plate engages with the positioning groove, achieving the purpose of automatic baffle fixing. This eliminates the tedious operation of manually pushing the clamping plate and facilitates the baffle fixing operation.

[0020] Furthermore, an annular rubber pad is fixed on the side wall of the baffle near the surveyor body. The annular rubber pad is located near the edge of the surveyor body and is made of rubber material with good elasticity.

[0021] By adopting the above technical solution, the ring-shaped rubber pad plays a good buffering and protective role during the process of the baffle and the surveying instrument body being in contact.

[0022] In summary, this utility model has the following beneficial effects: In this application, the operator can release the baffle by separating the locking plate and the positioning groove. Then, the baffle can be rotated away from the surveying instrument body until the buttons and display screen are fully exposed, allowing operation of the display screen and buttons on the surveying instrument body for measurement. After using the surveying instrument body, the baffle can be replaced by engaging the locking plate with the positioning groove to secure the baffle. This changes the structure of traditional technology, simplifies the operation steps, and improves efficiency. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-6 As shown in the figure, this application discloses a handheld real estate surveying instrument, including a surveying instrument body 1, a baffle 4, a locking mechanism 8, and auxiliary components 10. A pair of mounting shells 5 are fixed to the bottom of the surveying instrument body 1, and buttons 2 and a display screen 3 are provided on the surveying instrument body 1. The baffle 4 is disposed on the surveying instrument body 1 and is used to protect both the buttons 2 and the display screen 3. A connecting plate 6 is fixed to the bottom of the baffle 4 and rotatably disposed between the two mounting shells 5. Rotating shafts 7 are fixed to the side walls on both sides of the connecting plate 6, and the rotating shafts 7 pass through one side wall of the mounting shell 5 and are rotatably connected.

[0032] The locking mechanism 8 is used to fix the baffle 4 during protection. The locking mechanism 8 includes a locking component 81 and a support component 82. The locking component 81 includes a mounting block 811, a connecting block 812, a positioning block 813, and a locking plate 814. The mounting block 811 is fixed to the side wall of the surveying instrument body 1. The mounting block 811 is located near the top of the surveying instrument body 1, and a slot 8111 is provided on the top of the mounting block 811. A sliding groove 9 is provided on the side wall of the mounting block 811 near the locking plate 814. The connecting block 812 is fixed to the side wall of the baffle 4 at the position corresponding to the mounting block 811, and the positioning block 813 is inserted into the slot 8111. The positioning block 813 is fixed to the side wall of the connecting block 812 near the mounting block 811, and a positioning groove 8131 is provided at the bottom of the positioning block 813. The clamping plate 814 is slidably disposed on the side wall of the mounting block 811 away from the connecting block 812, and the clamping plate 814 is slidably engaged with the positioning groove 8131.

[0033] The support assembly 82 ensures that the card plate 814 remains in the insertion state with the positioning groove 8131. The support assembly 82 includes a slider 821 and a support spring 822. The slider 821 is fixed to the side wall of the card plate 814 near the mounting block 811, and the slider 821 slides in engagement with the slide groove 9. The support spring 822 is fixed between the bottom of the slider 821 and the inner bottom wall of the slide groove 9. A guide rod 11 is fixed between the inner top wall and the inner bottom wall of the slide groove 9, passing through the slider 821 and with clearance engagement, and the support spring 822 is sleeved on the guide rod 11.

[0034] When a real estate surveying instrument is needed for surveying work, the staff needs to pull the card plate 814 downwards and separate it from the positioning slot 8131. Then, the baffle 4 is rotated around the pivot 7 to the side away from the surveying instrument body 1 until the button 2 and the display screen 3 are fully exposed. The staff can then operate the display screen 3 and the button 2 on the surveying instrument body 1 to carry out the measurement work. (The staff holds the surveying instrument and presses the button 2 with the GPS logo. The GPS system obtains real-time positioning information such as longitude, latitude, and elevation. Then, it uses this information to calculate the coordinates of each point and processes the data through an algorithm to finally obtain the area and boundary position of the land. The measured data is displayed on the display screen 3. This part is described as prior art.) After the surveying instrument body 1 completes the measurement work, the operator first needs to push the clamping plate 814 to the lowest position. At this time, the slider 821 moves along the outer wall of the guide rod 11 to the lowest position in the slide groove 9. The support spring 822 is in a compressed state. The operator needs to put the baffle 4 back on and push the baffle 4 to drive the connecting block 812 and the positioning block 813 to reset. The positioning block 813 enters the clamping groove 8111. Finally, the clamping plate 814 is released. The clamping plate 814 is reset under the action of the support spring 822 at the bottom of the slider 821 and re-engages with the positioning groove 8131 at the bottom of the positioning block 813 to achieve the purpose of fixing the baffle 4. The baffle 4 plays a good protective role for the display screen 3 and the button 2, which changes the structure in the traditional technology, simplifies the operation steps, and improves the efficiency of use.

[0035] Auxiliary component 10 is mounted on mounting housing 5 and is used to automatically open baffle 4. Auxiliary component 10 includes a limiting plate 101 and a torsion spring 102. The limiting plate 101 is fixedly sleeved on the rotating shaft 7 and located inside the mounting housing 5. The torsion spring 102 is fixed between the side wall of the limiting plate 101 and the inner wall of the mounting housing 5. The torsion spring 102 is sleeved on the rotating shaft 7, and when the torsion spring 102 is in its original length state, the baffle 4 is in the fully open state. When the operator releases the baffle 4, due to the good torsional force of the torsion spring 102, the limiting plate 101 connected to the torsion spring 102, the rotating shaft 7 fixed to the limiting plate 101, the connecting plate 6 fixed to the rotating shaft 7, and the baffle 4 fixed to the connecting plate 6 all rotate until the torsion spring 102 is in its original length state, at which point the baffle 4 is in the fully open state.

[0036] A fixing block 12 is fixed on the side wall of the pallet 814 away from the mounting block 811. A wavy groove 13 is provided on the side wall of the fixing block 12 away from the pallet 814. The wavy groove 13 and the fixing block 12 reduce the probability of slippage when the operator pushes the pallet 814.

[0037] An inclined surface is provided at the intersection of the side wall of the positioning block 813 away from the connecting block 812 and the bottom of the positioning block 813. The distance between the inclined surface of the positioning block 813 and the connecting block 812 gradually decreases from top to bottom. The top of the clamping plate 814 is an upwardly convex arc shape. During the closing of the baffle 4, the inclined surface on the positioning block 813 contacts the arc surface at the top of the clamping plate 814, causing the positioning block 813 to press the clamping plate 814 downward. The support spring 822 is subjected to force and compressed until the positioning groove 8131 is in the corresponding position of the clamping plate 814. Then, the support spring 822 resets and drives the clamping plate 814 to reset through the slider 821. The clamping plate 814 engages with the positioning groove 8131, realizing the automatic fixing of the baffle 4. This eliminates the tedious operation of manually pushing the clamping plate 814 and facilitates the fixing of the baffle 4.

[0038] An annular rubber pad 14 is fixed on the side wall of the baffle 4 near the surveyor body 1, and the annular rubber pad 14 is positioned close to the edge of the surveyor body 1. The annular rubber pad 14 provides good cushioning and protection during the contact between the baffle 4 and the surveyor body 1.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
