[0032] Addressing the issue that existing positioning devices for pipeline detection are not detachable and are inconvenient to carry, this invention proposes a positioning device for pipeline detection, comprising a main unit 1 and a detection unit 2 detachably connected to the main unit 1. The main unit 1 has a receiving cavity, within which a main control board 16 is installed. The detection unit 2 has an inner cavity, within which an antenna assembly 21 is installed. The antenna assembly 21 is used to receive signals of a fixed frequency emitted by a transmitter in the detector. In this field, a commonly used fixed frequency is 512 Hz. By using the antenna assembly 21 of the positioning device to receive signals and then feeding them back to the main unit 1, a positioning indication function is achieved.

[0033] In this detection and positioning device, the main unit 1 is connected to the detection unit 2 by a first connector 10. The first connector 10 has a latch 101, and the end of the first connector 10 away from the main unit 1 has a receiving groove 102. A pin assembly 30 is disposed within the receiving groove 102, which enables electrical connection between the antenna assembly 21 and the main unit 1. A second connector 20 is provided in the detection unit 2. The second connector 20 has a hook 201 that engages with the latch 101. A portion of the second connector 20 passes into the receiving groove 102 of the first connector 10 and is latched to the second connector 20, thus achieving a detachable connection between the detection unit 2 and the main unit 1.

[0034] The snap-fit ​​connection between the first connector 10 and the second connector 20 facilitates the disassembly and storage of the detector 2 when it is not in use, thereby reducing its space occupation and making it easier to transport and store. At the same time, compared with threaded connections, the snap-fit ​​connection will not loosen during long-term use, which helps to ensure a stable connection between the detector 2 and the main unit 1.

[0035] Furthermore, the first connector 10 is also provided with an annular groove 103, which is located on the side of the receiving groove 102 away from the host 1. The second connector 20 is correspondingly provided with an outer ring 203 that mates with the annular groove 103. The outer ring 203 is fitted inside the annular groove 103, thus enabling the second connector 20 to be fitted onto the first connector 10. The hook 201 of the second connector 20 is located on the side of the outer ring 203 closer to the host 1. The corresponding snap-fit ​​structure can be as shown in the figure, where a notch is formed in the annular structure 202. When the second connector 20 is connected to the first connector 10, the annular structure 202 abuts against the inner side of the receiving groove 102, and the hook 201 engages with the buckle 101. In this solution, two sets of corresponding snap-fit ​​connection structures are provided and symmetrically arranged to ensure stability after engagement. In other embodiments, the annular structure 202 may be omitted, and the hook 201 may be directly connected to the buckle 101 for snap-fit ​​connection.

[0036] By setting an annular groove 103 at the front end of the receiving groove 102, and using the second connector 20 to be sleeved inside the first connector 10, a tight connection between the second connector 20 and the first connector 10 is achieved, ensuring the stable installation of the detection unit 2 and the host unit 1.

[0037] In this utility model, the ejector pin assembly 30 includes an ejector pin 301, an anti-bending plate 302 disposed at the front end of the ejector pin 301, and an ejector pin ring plate 303. The ejector pin 301 is placed in the receiving groove 102 by a fixing plate 304.

[0038] Specifically, the anti-bending plate 302 has a corresponding through hole for the ejector pin 301 to pass through. The ejector pin 301 is sleeved on the anti-bending plate 302 with its head protruding through. The anti-bending plate 302 is preferably made of a material with a certain buffering capacity, which can play a buffering role when the detection part 2 is combined with the main unit 1 to reduce damage to the ejector pin assembly 30. The ejector pin ring plate 303 is disposed at the end of the ejector pin 301 near the detection part 2. The ejector pin ring plate 303 is made of conductive material, and the sheet-like ejector pin ring plate 303 is used to further reduce the buffering effect on the ejector pin 301. The annular structure 202 has a second concave step 204 on its inner side. The ejector pin ring plate 303 is disposed on the second concave step 204. The receiving groove 102 has an inner ring 104, and the inner ring 104 has a first concave step 105. The ejector pin 301 is disposed on the first concave step 105 of the inner ring 104 by a fixing plate 304. A gap is provided between the inner ring 104 and the groove wall of the receiving groove 102 for the hook 201 to pass through. A gap is left between the top of the inner ring 104 and the front end of the second concave step 204 for the ejector pin ring plate 303 to buffer when fastened.

[0039] In this solution, the use of the ejector pin ring plate 303 and the anti-bending plate 302 can buffer and protect the ejector pin assembly 30 during the fastening process, reduce the damage to the connection between the host 1 and the detection part 2, and extend the service life of the device.

[0040] Specifically, the host unit 1 in this solution includes a first housing 11, which is formed by splicing two half-housings. The first connector 10 can be polygonal to facilitate its docking with the second connector 20 and locking with the host unit 1. The first connector 10 is located on the side of the host unit 1 near the detection unit 2, nested with the host unit 1 and locked with screws. The host unit 1 also has a handheld part 12, which is integrally formed with the first housing 11. The host unit 1 is shaped like a "7", and the handheld part 12 facilitates the handheld use of the positioning device. The main control board 16 is located in the cavity above the handheld part 12. The cavity corresponding to the handheld part 12 can be used to place the battery assembly 17. The battery assembly 17 is electrically connected to the main control board 16. A lower cover 18 is provided below the battery assembly 17 and interlocks with the first housing 11. Using the cavity corresponding to the handheld part 12 to place the battery assembly 17 can maintain the compactness and simplicity of the entire device. To facilitate the user's grip, anti-slip rubber 121 can be provided on the surface of the handheld part 12.

[0041] The main unit 1 also includes a display component 13 and a button component 14, which are electrically connected to the main control board 16. The display component 13 includes a display screen, which is preferably tilted and parallel to the handle for easy observation by the user while holding the device. The button component 14 is used to adjust the strength of the receiving frequency and to control the brightness of the display component 13. The main unit 1 also includes a speaker 15, which emits an audible prompt for location when the antenna component 21 detects a corresponding signal.

[0042] Furthermore, in this embodiment, the detection unit 2 includes a second housing 22, which includes an upper housing 221 and a lower housing 222. The upper housing 221 and the lower housing 222 form the inner cavity. One end of the second housing 22 is fitted inside the outer ring 203, and the second housing 22 and the second connecting member 20 can be locked together with screws. The antenna assembly 21 is placed in the inner cavity, and an EVA protective sleeve 23 is also provided around the antenna assembly 21 to protect it. As mentioned above, the antenna assembly 21 is used to detect the 512Hz frequency emitted by the transmitter. Its principle and structure are consistent with those disclosed in the prior art and have not been improved, so they will not be described in detail here. To further ensure that the detection unit 2 does not damage the built-in antenna assembly 21 when touching the bottom surface, the end of the second housing 22 away from the main unit 1 is also fitted with anti-collision soft rubber 24.

[0043] The positioning device for pipeline detection of this utility model uses a first connector 10 and a second connector 20 to set a snap connection between the detection part 2 and the main unit 1, and uses a pin assembly 30 for signal feedback. When not in use, the main unit 1 and the detection part 2 can be disassembled and stored to reduce the space occupied and make it easy to carry.

[0044] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
