Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a portable GPS positioning device for surveying and mapping. Background Technology

[0002] A positioning device is a device or system used to determine or fix the position of an object, and it is widely used in surveying, manufacturing, inspection and other fields. Depending on its function and technology, it can be divided into various types such as mechanical positioning, electronic positioning, and optical positioning. Specific design needs to be combined with the application scenario requirements.

[0003] For example, the GPS positioning device for topographic mapping disclosed in the authorization announcement number CN217978031U includes: a support rod and a positioning device body. A support plate is installed at the top of the support rod, and the positioning device body is installed on the top wall of the support plate. Movable blocks are evenly installed around the outer wall of the support plate, and a baffle is installed on the side wall of the movable block away from the support plate. The device is connected by the baffle installed on the outside of the support plate.

[0004] Although it ensures that the baffle will contact the ground first when the device is accidentally tilted, preventing the positioning device body from directly contacting the ground and avoiding damage to the positioning device body from falling to the ground, it also ensures the safety of the positioning device body in use.

[0005] However, this does not solve the problems that existing positioning devices of this type are generally not conducive to convenient and accurate positioning of the survey location, convenient height adjustment of the positioning device, convenient fixing and disassembly of the positioning device, which affects the portability of the positioning device, convenient circular rotation of the positioning device, and convenient tilt adjustment of the positioning device, which affects the survey range of the positioning device. Utility Model Content

[0006] The purpose of this utility model is to provide a portable GPS positioning device for surveying, in order to solve the problems mentioned in the background art, such as the inconvenience of convenient and accurate positioning of the survey location, the inconvenience of convenient height adjustment of the positioning device, the inconvenience of convenient fixing and disassembly of the positioning device, which affects the portability of the positioning device, the inconvenience of convenient circular rotation of the positioning device, and the inconvenience of convenient tilt adjustment of the positioning device, which affects the surveying range of the positioning device.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a portable mapping GPS positioning device, including a support base and a support frame. Three sets of equally spaced support frames are movably mounted on the bottom of the support base. Sliding frames are slidably mounted inside each support frame, extending to the outside of the support frame. A fixed frame is mounted on the end of each sliding frame away from the support frame. A rotating frame is mounted on the top of the support base. A rotating shaft is movably mounted at the center of the rotating frame. A rotating disk is mounted on the top of the rotating shaft. A flipping seat is symmetrically mounted on the top of the rotating disk. A flipping frame is movably mounted between the two sides of the flipping seat. A connecting frame is symmetrically mounted on the top of the flipping frame. Each connecting frame has a movably mounted limiting sleeve on its outer wall. A surveying instrument body is located on the outside of the connecting frame on one side of the limiting sleeve. Each sliding frame has a sliding groove on its outer wall. Each supporting frame on one side of the sliding groove has a symmetrically fitted arc-shaped sleeve. Each arc-shaped sleeve on one side of the sliding groove has a fixing bolt installed on its outer wall, extending into the sliding groove and slidably connected to it. Each connecting frame has a hinge shaft movably mounted on its outer wall near the limiting sleeve, connecting it to the limiting sleeve via the hinge shaft. Each connecting frame on its inner side away from the hinge shaft has a movably mounted limiting shaft, extending to the outside of the connecting frame. Each limiting shaft has a threaded rod fitted onto its surface, and each threaded rod has a threaded sleeve fitted onto its surface.

[0008] Furthermore, an electric push rod is installed at the top of the rotating frame, and slide rails are symmetrically installed on the top of the rotating frame on one side of the electric push rod.

[0009] Furthermore, a slider is slidably mounted on the top of each slide rail.

[0010] Furthermore, each slider has a movable block mounted on its top, and the output end of the electric push rod is connected to a set of movable blocks.

[0011] Furthermore, racks are installed on the outer walls of the moving blocks, and gears are fitted on the rotating shaft surface on one side of the racks, with the racks meshing with the gears.

[0012] Furthermore, a flipping shaft is installed inside the flipping frame, and the flipping shaft extends to the outside of the flipping frame, and the flipping shaft is movably connected to the flipping seat.

[0013] Furthermore, a worm gear is fitted onto the surface of the flipping shaft, and a power motor is installed on the outer wall of the flipping seat on one side of the worm gear.

[0014] Furthermore, a worm gear is installed at the output end of the power motor, and the worm gear meshes with a worm wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the positioning device not only realizes convenient and accurate positioning of the surveying location, but also facilitates convenient height adjustment, convenient fixing and disassembly of the positioning device, and improves the portability of the positioning device. In addition, it facilitates convenient circumferential rotation of the positioning device and convenient tilt adjustment of the surveying angle, thereby increasing the surveying range of the positioning device.

[0016] Move the support base and the surveying instrument body to the location to be surveyed. Manually rotate the fixing bolt, which loosens the two sets of arc sleeves. Manually push the sliding frame, which moves to the appropriate position. The fixing bolt slides inside the groove. After the sliding frame moves to the appropriate position, manually rotate the fixing bolt again to loosen the two sets of arc sleeves, thus easily fixing the sliding frame. When the sliding frame is adjusted to the appropriate height, manually insert the three sets of fixing frames into the ground to provide stable support for the support base. Place the surveying instrument body on the surface of the two sets of connecting frames. Manually rotate the two sets of limiting sleeves, which rotate around the hinge axis to fit onto the surface of the surveying instrument body. When not in use, the surveying instrument body can be disassembled for easy individual storage, improving its safety. This design allows for convenient adjustment and carrying of the positioning device, making it easy to detach the surveying instrument and move it independently, thus enhancing the convenience of carrying and moving the positioning device.

[0017] An electric push rod drives a moving block, which in turn drives a rack, which in turn drives a gear, which in turn drives a rotating shaft. A rotating frame provides movable support for the rotating shaft, which in turn drives a rotating disk. The rotating disk then drives the tilting seat, tilting frame, connecting frame, surveying instrument body, and limit sleeve to rotate, facilitating convenient adjustment of the surveying instrument body's position. When the angle of the surveying instrument body needs to be adjusted, a power motor drives a worm gear, which in turn drives the tilting shaft, which in turn drives the tilting frame, which in turn drives the surveying instrument body, connecting frame, and limit sleeve to rotate, facilitating angle adjustment of the surveying instrument body. This enables convenient multi-position surveying with the positioning device, facilitates convenient circular rotation of the positioning device, and facilitates convenient tilting adjustment of the surveying angle, thus increasing the surveying range of the positioning device.
