Description

Technical Field

[0001] This application relates to the technical field of GPS receivers, and more particularly to a GPS receiver for surveying. Background Technology

[0002] In today's surveying and mapping field, GPS receivers, as key devices for obtaining accurate geographical location information, are widely used in numerous projects such as topographic surveying, engineering surveying, and land demarcation. Taking the topographic surveying stage of large-scale construction projects as an example, surveyors need to use GPS receivers to accurately measure the topography of the construction site, providing basic data support for subsequent architectural design and construction.

[0003] Regarding the aforementioned technologies, it has been found that traditional GPS receivers are directly mounted on top of a bracket during actual use. Different models of GPS receivers require different mounting brackets, resulting in poor versatility. Furthermore, they cannot be flexibly disassembled and protected when not in use, making them susceptible to external environmental corrosion, which affects signal reception and transmission, leading to deviations in measurement data and significantly shortening the lifespan of the equipment. Utility Model Content

[0004] To enable flexible installation of different models of GPS receivers, this application provides a GPS receiver for surveying.

[0005] The GPS receiver for surveying provided in this application adopts the following technical solution:

[0006] A GPS receiver for surveying includes a bottom bracket, a top bracket mounted on the upper surface of the bottom bracket, the top bracket being fixedly connected to the bottom bracket, a device housing mounted on the upper surface of the top bracket, the device housing being fixedly connected to the top bracket, a pick-and-place opening on the front surface of the device housing, and two sets of lifting frames symmetrically mounted inside the device housing, the lifting frames being slidably connected to the device housing, an auxiliary cover fixedly mounted on the head of the lifting frame, two sets of clamping frames symmetrically mounted on the auxiliary cover, the clamping frames being horizontally slidably connected to the auxiliary cover, and an elastic component for pulling the clamping frames toward the center fixedly mounted in the middle of the lower surface of the auxiliary cover.

[0007] By adopting the above technical solution, a bottom support is used as the base of the device. This support can be a three- or four-legged, retractable support that can be flipped open and placed on the desired surface. The bottom support then supports the top support, which in turn supports the device housing. This combination of the bottom support, top support, and device housing forms a stable support and protective structure, providing a fundamental guarantee for the normal operation of the GPS receiver. The device housing allows the GPS receiver to be stored when not in use, and when needed, the receiver's outlet can be placed on the auxiliary cover above the housing for signal reception. A lifting frame is installed within the device, and its sliding connection to the housing allows for easy raising and lowering of the auxiliary cover, facilitating the placement and removal of the GPS receiver module. The clamping bracket and elastic components on the auxiliary cover effectively hold and secure the GPS receiver module, preventing wobbling during use and improving surveying accuracy and stability. Furthermore, once the GPS receiver module is placed inside the housing, the clamping bracket and elastic components further ensure stable placement.

[0008] Optionally, the top support includes a base and a support rod. The base is fixedly installed on the upper surface of the bottom support by bolts, and the support rod is vertically installed at the center of the upper surface of the base, and the support rod is inserted and fixedly connected to the base.

[0009] By adopting the above technical solution, the top support frame is fixed to the bottom support with bolts, ensuring a firm connection. The support rod is plugged into the frame for easy installation and disassembly, while providing stable support for the equipment casing and ensuring the overall stability of the equipment.

[0010] Optionally, the equipment housing includes a bottom plate and a protective side plate, the protective side plate being installed on the upper surface of the bottom plate and integrally formed with the bottom plate.

[0011] By adopting the above technical solution, the bottom plate and protective side plate of the equipment shell are integrally formed, which enhances the overall strength and sealing of the equipment shell. When the lifting frame drives the auxiliary cover to close, it can effectively prevent external dust, moisture and other substances from entering the equipment, and play a good protective role for the internal components.

[0012] Optionally, the lifting frame includes an arc-shaped seat plate and a sliding rod. The sliding rod is vertically installed at both ends of the arc-shaped seat plate, and the lower end of the sliding rod is fixedly connected to the arc-shaped seat plate. The sliding rod is slidably installed on the bottom plate of the shell.

[0013] By adopting the above technical solution, the structure of the lifting frame's arc-shaped seat plate and sliding rod, allows the lifting frame to slide more smoothly within the equipment housing. The sliding connection between the sliding rod and the housing bottom plate provides stable guidance for the lifting of the auxiliary cover, ensuring convenient and reliable operation. Furthermore, by fixing the auxiliary cover to the head of the sliding rod, it can slide synchronously with the sliding rod.

[0014] Optionally, the upper surface of the arc-shaped base plate is equipped with a plurality of magnetic blocks that attract each other to the bottom plate of the shell, and the magnetic blocks are fixedly connected to the arc-shaped base plate.

[0015] By adopting the above technical solution, the magnetic blocks on the arc-shaped base plate and the bottom plate of the shell attract each other. When the lifting frame is lifted, the arc-shaped base plate can be attracted and fixed to the lower end face of the equipment shell by the magnetic blocks, ensuring the stability when the auxiliary cover is opened, and facilitating the stable placement of the GPS receiver module through the auxiliary cover.

[0016] Optionally, the auxiliary cover includes a top platform and a front cover that mates with the loading and unloading port of the equipment housing. The front cover is vertically installed on the lower end face of the top platform, and the top platform and the front cover are integrally formed. The top platform is also provided with a sliding groove for the clamping frame to be slidably installed.

[0017] By adopting the above technical solution, and designing the auxiliary cover platform as an integrally formed structure of top and front cover plates, the overall structure is simple and has high strength. The front cover plate cooperates with the loading and unloading port of the equipment housing, effectively sealing the loading and unloading port to prevent external debris from entering and protecting the GPS receiver module placed in the equipment housing. The sliding groove on the top platform provides a track for the sliding of the clamping frame, ensuring the smooth movement of the clamping frame.

[0018] Optionally, the clamping frame includes an upper clamping plate, a middle plate, and a lower clamping plate. The middle plate is slidably installed in a sliding groove, and the upper and lower clamping plates are fixedly installed at the upper and lower ends of the middle plate.

[0019] By adopting the above technical solution, and designing the clamping frame with a structure consisting of an upper clamping plate, a middle plate, and a lower clamping plate, the GPS receiver module can be clamped from multiple directions, improving clamping stability. The sliding of the middle plate in the groove allows the clamping frame to be flexibly adjusted according to the size of the receiver module, enhancing the versatility of the equipment.

[0020] Optionally, the elastic component includes a middle seat plate, a tension spring, and a connecting plate fixedly connected to the lower clamping plate. The middle seat plate is fixedly installed on the lower end face of the top platform. The tension spring is symmetrically installed on both sides of the middle seat plate. One end of the tension spring is fixedly connected to the middle seat plate, and the connecting plate is fixedly connected to the other end of the tension spring.

[0021] By adopting the above technical solution, and designing the elastic component as a structure in which a middle seat plate, a tension spring, and a connecting plate cooperate, the tension spring of the elastic component can provide tension during use, causing the connecting plate to drive the lower clamping plate to move towards the center, thereby generating a clamping force on the GPS receiver module by the clamping frame. This elastic clamping method can adapt to receiver modules of different sizes, and can also play a buffering role when the equipment is subjected to vibration, protecting the receiver module from damage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The device housing and auxiliary cover design facilitate the protection of the GPS receiver module when not in use, effectively preventing external dust and moisture from corroding the GPS receiver module and extending its service life. The sliding design of the lifting frame allows for easy raising and lowering of the auxiliary cover, facilitating the loading and unloading of the GPS receiver module. Simultaneously, the elastic clamping mechanism of the clamping frame enables quick and stable fixation of the receiver module, and the two clamping methods (top and bottom) facilitate both use and storage of the GPS receiver module. The clamping frame can be flexibly adjusted according to the size of the receiver module, making it suitable for GPS receiver modules of different specifications, enhancing the versatility and applicability of the device.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a GPS receiver for surveying. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, a GPS receiver for surveying includes a bottom bracket 1, a top bracket 2 mounted on the upper surface of the bottom bracket 1, the top bracket 2 being fixedly connected to the bottom bracket 1, a device housing 3 mounted on the upper surface of the top bracket 2, the device housing 3 being fixedly connected to the top bracket 2, a pick-and-place opening on the front surface of the device housing 3, and two sets of lifting frames 4 symmetrically mounted in the device housing 3, the lifting frames 4 being slidably connected to the device housing 3, an auxiliary cover 5 fixedly mounted on the head of the lifting frame 4, two sets of clamping frames 6 symmetrically mounted on the auxiliary cover 5, the clamping frames 6 being horizontally slidably connected to the auxiliary cover 5, and an elastic component 7 for pulling the clamping frames 6 towards the center fixedly mounted in the middle of the lower surface of the auxiliary cover 5. The bottom bracket 1 serves as the base of the device. This can be a three- or four-legged, retractable bracket that can be flipped open and placed on the desired surface. The bottom bracket 1 supports the top bracket 2, which in turn supports the device housing 3. Together, these components form a stable support and protective structure, ensuring the normal operation of the GPS receiver. The device housing 3 allows the GPS receiver to be stored away when not in use. When needed, the receiver can be placed on the auxiliary cover 5 on top of the housing 3 to receive signals. A lifting frame 4, slidably connected to the housing 3, allows the auxiliary cover 5 to be easily raised and lowered, facilitating the placement and removal of the GPS receiver module. By setting the clamping frame 6 and elastic component 7 on the auxiliary cover 5, the GPS receiver module can be effectively clamped and fixed to prevent it from shaking during use, thereby improving the accuracy and stability of the survey. Furthermore, when the GPS receiver module is placed into the equipment housing 3, it can also be clamped by the clamping frame 6 and elastic component 7 to ensure the stability of the placement.

[0032] Reference Figure 2 and Figure 4 As shown, the top support 2 includes a base 21 and a support rod 22. The base 21 is bolted to the upper surface of the bottom support 1. The support rod 22 is vertically installed at the center of the upper surface of the base 21, and is plugged into and fixedly connected to the base 21. The base 21 of the top support 2 is bolted to the bottom support 1, ensuring a firm connection. The plugged connection between the support rod 22 and the base 21 facilitates installation and disassembly, while providing stable support for the equipment housing 3, ensuring the overall stability of the equipment.

[0033] Reference Figure 2 As shown, the equipment housing 3 includes a bottom plate 31 and a protective side plate 32. The protective side plate 32 is installed on the upper surface of the bottom plate 31 and is integrally formed with the bottom plate 31. The integral formation of the bottom plate 31 and the protective side plate 32 of the equipment housing 3 enhances the overall strength and sealing of the equipment housing 3. When the lifting frame 4 drives the auxiliary cover 5 to close, it can effectively prevent external dust, moisture, etc. from entering the equipment, thus providing good protection for the internal components.

[0034] Reference Figure 5 As shown, the lifting frame 4 includes an arc-shaped base plate 41 and a sliding rod 42. The sliding rod 42 is vertically installed at both ends of the arc-shaped base plate 41, and the lower end of the sliding rod 42 is fixedly connected to the arc-shaped base plate 41. The sliding rod 42 is slidably installed on the bottom plate 31 of the housing. The coordinated structure of the arc-shaped base plate 41 and the sliding rod 42 of the lifting frame 4 makes the sliding of the lifting frame 4 within the equipment housing 3 smoother. The sliding connection between the sliding rod 42 and the bottom plate 31 provides a stable guide for the lifting of the auxiliary cover 5, ensuring convenient and reliable operation. Furthermore, by fixing the auxiliary cover 5 to the head of the sliding rod 42, it can slide synchronously with the sliding rod 42. Several magnetic blocks that attract each other to the bottom plate 31 are installed on the upper surface of the arc-shaped base plate 41, and the magnetic blocks are fixedly connected to the arc-shaped base plate 41. The magnetic blocks on the arc-shaped base plate 41 are attracted to the bottom plate 31 of the shell. When the lifting frame 4 is lifted, the magnetic blocks can attract and fix the arc-shaped base plate 41 to the lower end face of the equipment shell 3, ensuring the stability of the auxiliary cover 5 when it is opened, and facilitating the stable placement of the GPS receiver module through the auxiliary cover 5.

[0035] Reference Figure 5As shown, the auxiliary cover 5 includes a top plate 51 and a front cover 52 that mates with the loading / unloading port of the equipment housing 3. The front cover 52 is vertically mounted on the lower end face of the top plate 51, and the top plate 51 and the front cover 52 are integrally formed. The top plate 51 also has a sliding groove 511 for the sliding installation of the clamping frame 6. By designing the auxiliary cover 5 as an integrally formed structure of the top plate 51 and the front cover 52, the overall structure is simple and has high strength. The front cover 52, mates with the loading / unloading port of the equipment housing 3, effectively seals the loading / unloading port, preventing external debris from entering and protecting the GPS receiver module placed inside the equipment housing 3. The sliding groove 511 on the top plate 51 provides a track for the sliding of the clamping frame 6, ensuring the smooth movement of the clamping frame 6.

[0036] Reference Figure 5 As shown, the clamping frame 6 includes an upper clamping plate 61, a middle plate 62, and a lower clamping plate 63. The middle plate 62 is slidably mounted in the slide groove 511, while the upper clamping plate 61 and the lower clamping plate 63 are fixedly mounted at the upper and lower ends of the middle plate 62. By designing the clamping frame 6 with the upper clamping plate 61, middle plate 62, and lower clamping plate 63 cooperating, the GPS receiver module can be clamped from multiple directions, improving clamping stability. The sliding of the middle plate 62 in the slide groove 511 allows the clamping frame 6 to be flexibly adjusted according to the size of the receiver module, enhancing the versatility of the device.

[0037] Reference Figure 3 and Figure 6 As shown, the elastic component 7 includes a middle base plate 71, a tension spring 72, and a connecting plate 73 fixedly connected to the lower clamping plate 63. The middle base plate 71 is fixedly installed on the lower end face of the top platform 51. The tension springs 72 are symmetrically installed on both sides of the middle base plate 71, with one end of the tension spring 72 fixedly connected to the middle base plate 71 and the connecting plate 73 fixedly connected to the other end of the tension spring 72. By designing the elastic component 7 into a structure in which the middle base plate 71, tension spring 72, and connecting plate 73 cooperate, the tension spring 72 of the elastic component 7 can provide tension during use, causing the connecting plate 73 to drive the lower clamping plate 63 to move towards the center, thereby generating a clamping force on the GPS receiver module by the clamping frame 6. This elastic clamping method can adapt to receiver modules of different sizes and can play a buffering role when the equipment is subjected to vibration, protecting the receiver module from damage.

[0038] The implementation principle of a GPS receiver for surveying in this embodiment is as follows: When using the GPS receiver, first pull the auxiliary cover 5 upwards, and the lifting frame 4 will rise accordingly, opening the loading and unloading port of the equipment housing 3. Then, place the GPS receiver module on the auxiliary cover 5, pull the clamping frames 6 open to both sides, place the receiver module in a suitable position, and then release the clamping frames 6. Under the action of the elastic component 7, the clamping frames 6 will automatically move towards the center to clamp and fix the receiver module. Furthermore, when the lifting frame 4 is lifted, the magnetic block attracts the bottom plate 31 of the housing, allowing the auxiliary cover 5 to stably support the GPS receiver, completing the installation of the equipment. During the surveying process, the equipment can stably receive signals, providing accurate location information for the surveying work.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
