Detailed Implementation

[0023] 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.

[0024] Reference Figure 1-4 A detachable ranging wheel structure includes a detection body 100, a connector 102 mounted on the top of the detection body 100, handles 101 fixedly mounted on both sides of the top of the detection body 100, and a ranging component for testing provided on the front surface of the detection body 100. The ranging component includes a snap-fit ​​fixing seat 200, a ranging mounting seat 103 mounted on the front surface of the snap-fit ​​fixing seat 200, and a ranging wheel 104 mounted on the front surface of the ranging mounting seat 103. At the same time, the ranging component and the front surface of the detection body 100 are provided with an alignment assembly groove 201. The ranging component and the detection body 100 are connected and snapped together by the snap-fit ​​fixing seat 200 and the alignment assembly groove 201. By expanding the convenient disassembly and assembly structure, the convenience of use is improved, and the device can be used better.

[0025] Reference Figure 1-4 Specifically, the rear surface of the snap-fit ​​fixing base 200 is provided with an integrated limiting protrusion 204, and the inner side of the alignment assembly groove 201 is provided with a limiting slot 202. After the snap-fit ​​fixing base 200 and the alignment assembly groove 201 are aligned, they are limited and fixed by the limiting slot 202 and the limiting protrusion 204. The longitudinal snap-fit ​​alignment limits and fixes the transverse side. Specifically, positioning insertion holes 203 are provided on both sides of the limiting slot 202, and the front surface of the snap-fit ​​fixing base 200 is provided with a moving groove 205. A positioning rod 207 is provided in the moving groove 205, and a buffer spring 208 is fitted at one end of the positioning rod 207. A movable locking plate 206 is also installed in the moving groove 205. The positioning rod 207 passes through the movable clamping plate 206, and the movable clamping plate 206 is limited in movement within the actuation groove 205 by the positioning rod 207. At the same time, a positioning insert rod 209 is also provided on the other side of the movable clamping plate 206. One end of the positioning insert rod 209 is also provided, and the positioning insert rod 209 passes through the edge of the snap-fit ​​fixing seat 200. When the snap-fit ​​fixing seat 200 moves to the bottom of the alignment assembly groove 201, the positioning insert rod 209 is inserted into the positioning hole 203 for positioning and snap-fit. Through the lateral snap-fit ​​alignment, the longitudinal direction is limited and fixed. The combination of longitudinal and lateral fixation better ensures stability and improves the convenience of disassembly and assembly.

[0026] Reference Figure 1 , Figure 5The inner side of the plug-in socket 102 is provided with a terminal block 105. An integrated snap-fit ​​protrusion 304 is provided at the top edge of the plug-in socket 102. A dustproof protective cover 300 is installed on the top of the plug-in socket 102. An integrated docking chuck 301 is provided at the bottom edge of the dustproof protective cover 300. The docking chuck 301 has an alignment groove 303. The dustproof protective cover 300 and the plug-in socket 102 are aligned and locked together by the alignment groove 303 and the snap-fit ​​protrusion 304. At the same time, a sealing gasket 302 is also bonded to the bottom of the docking chuck 301. The sealing gasket 302 is made of rubber. The dustproof protective cover 300 can play a certain protective role. The sealing gasket 302 can better seal and prevent dust, while also facilitating disassembly and use, further improving the practicality of the equipment.

[0027] Working principle: When detecting distance in engineering, the ranging wheel 104 is pressed against the concrete surface. During the radar's forward movement, the friction between the ranging wheel 104 and the concrete surface drives the ranging wheel 104 to rotate, generating an electronic pulse to trigger the radar host to collect data. Before using the device, the ranging component is removed. A limiting protrusion 204 is provided on the back of the locking and fixing seat 200 of the ranging component. The locking and fixing seat 200 is aligned with the alignment and assembly groove 201 opened on the surface of the detection body 100. At the same time, the limiting protrusion 204 and the limiting slot 20 inside the alignment and assembly groove 201 are aligned. 2. Limiting assembly allows for snap-fit ​​assembly. During snap-fit, the movable locking plate 206 located on the snap-fit ​​fixing seat 200 and inside the actuating groove 205 can be manually pressed, causing the two symmetrical movable locking plates 206 to move closer to each other. Simultaneously, the positioning rod 209 retracts into the actuating groove 205. As the movable locking plates 206 move, they are limited by the positioning rod 207 and deform by squeezing the buffer spring 208. The deformed buffer spring 208 generates a certain restoring force. When the snap-fit ​​fixing seat 200 slides to the bottom of the alignment assembly groove 201, the positioning rod 209... After alignment with the positioning socket 203, the buffer spring 208 pushes the positioning rod 209 into the positioning socket 203, thus securing it in place. At this point, the device can be used to measure distances via the measuring wheel 104. When the device requires maintenance after a period of use, the above operation can be repeated. Moving the movable locking plate 206 removes the locking seat 200 from the alignment assembly slot 201. After the entire distance measuring assembly is disassembled, maintenance can be performed more easily, further improving the convenience and efficiency of the device's maintenance process. During the movement of the detection body 100, a dustproof protective cover 300 is provided on the plug-in 102 on the top of the detection body 100. The dustproof protective cover 300 is fixed by a rotating snap-fit ​​method, which is convenient for disassembly and assembly. The dustproof protective cover 300 can also protect the terminal block 105 inside the plug-in 102, preventing dust and impurities from entering the terminal block 105, preventing disconnection or poor contact during use, and preventing the terminal block 105 from being damaged by bumps. This improves the safety of the device and ensures the stability of the device during operation.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
