Description

Technical Field

[0001] This invention relates to the technical field of positioning equipment, and in particular to a precision positioning device for indoor use. Background Technology

[0002] Indoor precision positioning equipment is a complete set of hardware and software devices built using technologies such as wireless, acoustic waves, optics, and vision when GPS satellite signals cannot penetrate buildings. It is used to collect and track the location coordinates of people, vehicles, and materials in buildings, factories, and underground spaces. According to the accuracy, it is divided into three categories: meter-level popular type, centimeter-level industrial precision type, and millimeter-level ultra-high precision type.

[0003] The prior art patent number CN217114749U discloses a dustproof indoor precision positioning terminal. By setting up a storage slot and a limiting block, after the utility model is used, the user can flip the signal antenna so that the signal antenna is stored inside the storage slot. As the signal antenna rotates, the top of the signal antenna will press the limiting block, thereby pressing the limiting block to move in the movable slot. The limiting block is used to limit and fix the end of the signal antenna, so that the signal antenna will not shake during the movement of the utility model, thus ensuring the stable carrying of the utility model.

[0004] However, in actual use, since the display screen is directly exposed on the main body of the equipment, it is prone to scratches or even damage when subjected to accidental impacts. Therefore, there is room for improvement. Summary of the Invention

[0051] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0052] This invention discloses an indoor precision positioning device. (Refer to...) Figures 1-7 A precision positioning device for indoor use includes: a main body 1, with a groove 3 on the upper right side of the main body 1, in which a signal antenna 2 is rotatably mounted; a display screen 6 mounted on the main body 1; a flip-up protective structure, with the display screen 6 mounted on the main body 1 via the flip-up protective structure; a first buffer structure mounted on the flip-up protective structure to buffer impacts; a second buffer structure mounted on the first buffer structure to provide further shock absorption during the first buffering action; a rotating positioning structure mounted on the main body 1, which rotates the flip-up protective structure as the main body 1 rotates; a movable hook structure mounted on the rear side of the main body 1; and a squeeze-out structure mounted on the movable hook structure.

[0053] See Figure 1 , Figure 2 , Figure 3 and Figure 7The flip-over protective structure includes: a storage slot 4 located on the upper front of the main body 1 of the equipment; rotating shafts 7 are rotatably connected to the walls of both ends of the storage slot 4; a flip-over frame 5 is installed between the two rotating shafts 7; and a display screen 6 is fixedly embedded in the flip-over frame 5. Multiple spring plates 8 are arranged on the rear side of the flip-over frame 5, each spring plate 8 being arched in shape. The multiple spring plates 8 are interconnected, and connecting strips 9 are connected to the two spring plates 8 on both sides. A buffer ring 10 is provided at one end of each connecting strip 9. The buffer ring 10 is movably sleeved on the rotating shaft 7; the first buffer structure includes: a second buffer ring 12 movably sleeved on the rotating shaft 7, with a spring 11 connecting the second buffer ring 12 and the first buffer ring 10; the second buffer structure includes: a buffer plate 13 movably sleeved on the rotating shaft 7, with the buffer plate 13 tightly attached to the second buffer ring 12; buffer rods 14 are connected to both ends of the buffer plate 13, and buffer grooves 15 are provided on the groove walls at both ends of the receiving groove 4 for the buffer rods 14 to be movably inserted. One end of buffer rod 14 is connected to buffer rod 2 17, which moves through the wall of buffer groove 1 15. A spring 4 16 is fitted onto buffer rod 2 17, with its two ends connected to buffer rod 14 and the wall of buffer groove 1 15 at one end, respectively. A limiting block 18 is installed at one end of buffer rod 2 17, and a limiting groove 19 is provided on the outside of the equipment body 1 for the limiting block 18 to move into. The rotation positioning structure includes a pressing groove 23 on one side of the equipment body 1. 23 is located between two limiting grooves 19 in one set; a rotating rod 21 is movably inserted into the pressing groove 23, a fixing ring 24 is fixedly sleeved on the rotating rod 21, and a cylindrical rod 25 is connected to the side of the fixing ring 24; two straight grooves 26 are opened on the pressing groove 23 along the length of the rotating rod 21, and a semi-annular groove 27 is opened on the groove wall of the pressing groove 23. The two ends of the semi-annular groove 27 are respectively connected to the two straight grooves 26, and one end of the cylindrical rod 25 is movably inserted into one of the straight grooves 26. A rotating block 22 is set at one end of the rotating rod 21.The other end of the rotating rod 21 is fixedly connected to a connecting rod 20. One end of the connecting rod 20 is movably inserted into the rotating shaft 7. The end face of the connecting rod 20 is square. One end of the rotating rod 21 is rotatably fitted with a rotating sleeve 29. A spring 28 is connected between the rotating sleeve 29 and the groove wall of one end of the pressing groove 23. When carrying this equipment, firstly, the rotating block 22 is used to push the rotating rod 21 to move in the pressing groove 23, compressing the spring 28. At the same time, the rotating rod 21 drives one end of the cylindrical rod 25 on the fixed ring 24 to slide in one of the straight grooves 26 until one end of the cylindrical rod 25 slides into the semi-annular groove 27. Then, the rotating block 22 is used to rotate the rotating rod 21, driving the cylindrical rod 25 to slide from the semi-annular groove 27 to another straight groove 26. During the rotation, the connecting rod 20 drives the rotating shaft 7 and the flip frame 5 to rotate half a turn as a whole, thus turning the display screen 6. Rotate and store the display screen 6 into the storage slot 4, then release the rotating block 22. Under the elastic force of the second spring 28, push the rotating rod 21 and the rotating block 22 to move in the opposite direction and reset, causing one end of the cylindrical rod 25 to slide into another straight slot 26, thus positioning the flipped display screen 6 and the flip frame 5 as a whole. In this way, the display screen 6 is flipped and stored in the storage slot 4, which not only provides dust protection but also reduces the problem of accidental scratches during carrying. When the flip frame 5 is subjected to an accidental impact during carrying, the deformation of the spring plate 8 is used to dampen and buffer the impact. Furthermore, the connecting bar 9 pushes the buffer ring 10 to move and compress the spring 11. When the spring 11 pushes the buffer ring 12 to move, it causes the fourth spring 16 to compress, further improving the safety protection of the display screen 6.

[0054] See Figures 4-6The movable hook structure includes: a second groove 31 on the rear side of the equipment body 1, with sliding grooves 32 on both the front and rear sides of the groove wall of the second groove 31, and a slider sliding in the sliding groove 32, with a movable frame 33 between the two sliders; a hook 30 is installed on the movable frame 33; the extrusion and removal structure includes: a third groove 40 on the rear side of the equipment body 1 above the second groove 31, with a fixed rod 39 connected to the inner end groove wall of the third groove 40, a sleeve 42 movably sleeved on the fixed rod 39, a button 43 installed at one end of the sleeve 42, and a third spring 41 sleeved on the sleeve 42, with the two ends of the third spring 41 connected to the button 43 and the inner groove wall of the third groove 40 respectively; a through groove 38 communicating with the second groove 31 is opened on the groove wall of the third groove 40, and one end of the sleeve 42 is inserted into the through groove 38. The device consists of a drive block 37; a rotating shaft 36 is rotatably connected between the front and rear sides of the through groove 38, and a gear 35 is fixedly sleeved on the rotating shaft 36; a drive bar 34 is set in the middle of the upper part of the moving frame 33; both the drive bar 34 and the drive block 37 are provided with teeth that mesh with the gear 35. When carrying the device, pressing the button 43 on the rear side of the main body 1 causes the sleeve 42 to move on the fixed rod 39, and the drive block 37 drives the gear 35 to rotate. The drive bar 34 pushes out the hook 30 from the groove 31, and hangs the hook 30 on the wearer's belt, making it more convenient to carry the device. After the button 43 moves, it causes the spring 41 to compress. Under the elastic force of the spring 41, the hanging of the hook 30 is improved and the problem of falling is reduced. The structure is simple and the function is practical.

[0055] The implementation principle of an indoor precision positioning device according to an embodiment of the present invention is as follows: When carrying the device, firstly, the rotating block 22 pushes the rotating rod 21 to move in the pressing groove 23, compressing the second spring 28. At the same time, the rotating rod 21 drives one end of the cylindrical rod 25 on the fixed ring 24 to slide in one of the straight grooves 26 until one end of the cylindrical rod 25 slides into the semi-annular groove 27. Then, the rotating block 22 rotates the rotating rod 21, causing the cylindrical rod 25 to slide from the semi-annular groove 27 to another straight groove 26. During the rotation, the connecting rod 20 drives the rotating shaft 7 and the flip frame 5 to rotate half a turn as a whole, rotating and storing the display screen 6 into the storage groove 4. Then, the rotating block 22 is released, and under the elastic force of the second spring 28, the rotating rod 21 and the rotating block 22 are pushed to move in the opposite direction to reset, causing one end of the cylindrical rod 25 to slide into the other straight groove 26. The display screen 6 and the flip frame 5 are positioned as a whole, so that the display screen 6 can be flipped and stored in the storage slot 4. This not only serves to prevent dust but also reduces the risk of accidental scratches during carrying. When the flip frame 5 is subjected to an accidental impact during carrying, the deformation of the spring plate 8 will dampen the impact. Furthermore, the connecting bar 9 will push the buffer ring 10 to move and compress the spring 11. When the spring 11 pushes the buffer ring 2 12 to move, it will cause the spring 4 16 to compress, further improving the safety protection of the display screen 6. Finally, pressing the button 43 on the rear side of the main body 1 will move the sleeve 42 on the fixing rod 39. The driving block 37 will drive the gear 35 to rotate, and the driving bar 34 will push the hook 30 out of the groove 2 31 to hang it on the wearer's belt, making it more convenient to carry.

[0056] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
