Description
Technical Field
[0001] This utility model relates to the field of pipeline leak detection technology, and in particular to a multi-functional handle for a leak detector. Background Technology
[0002] Urban underground pipelines refer to the pipelines and ancillary facilities within a city, including those for water supply, drainage, gas, heating, electricity, communications, broadcasting and television, and industry. They are vital infrastructure and "lifelines" ensuring the operation of the city. Among these, underground water pipes are an indispensable lifeline for residents. When a leak occurs in a underground water pipe, a specialized leak detector is needed to locate the leak. The leak detector mainly consists of circuits for pickup, handheld preamplifier, main amplifier, signal processing, and power amplifier. The signal is then transmitted to the operator via headphones, a multimeter, and an LED light beam for listening and observation. The operator then comprehensively analyzes the signal to determine the location and size of the leak. During the detection process, the microphone is typically controlled by a handheld handle connected to a cable. The cable and microphone are detachable for easy storage. The cable and handle are usually secured manually, but in practice, the cable length cannot be adjusted, sometimes resulting in insufficient or excessive cable length, causing inconvenience for operators.

[0030] This utility model proposes a multi-functional handle for a leak detector.
[0031] like Figures 1 to 2 The multi-functional handle of the leak detector shown includes a handle body 1, a housing 2 at one end of the handle body 1, a receiving space 21 formed inside the housing 2, an inlet and outlet 22 communicating with the receiving space 21 on the side of the housing 2 away from the handle body 1, a cover 4 is provided at the inlet and outlet 22, the receiving space 21 is used to receive cables, and a connecting connector 23 is provided on the side of the receiving space 21 near the handle body 1, the connecting connector 23 is used to detachably connect cables, and electrically connect to the control circuit inside the handle body 1.
[0032] A housing 2 is provided at the end of the handle body 1. The housing 2 forms a receiving space 21 and an inlet / outlet 22, which facilitates the cable to be stored in the receiving space 21. A connecting connector 23 is provided in the receiving space 21 so that the cable can be connected to the control circuit in the handle body 1. The cable can be pulled out and put in through the receiving space 21 so that the operator can pull out a cable of appropriate length from the receiving space 21 according to the actual working conditions.
[0033] A winding post 24 is installed within the receiving space 21, located between the inlet / outlet 22 and the connecting joint 23. One end of the winding post 24 is connected to the inner wall of the receiving space 21, and a cable passage 25 is formed between the other end of the winding post 24 and the inner wall of the receiving space 21 at intervals. The winding post 24 is used for winding cables, so that the cables can be better secured within the receiving space 21. The cable passage 25 facilitates cable winding by workers.
[0034] An anti-slip layer is provided on the outer surface of the winding post 24.
[0035] A first threaded through hole 26 is formed on the side wall of the housing 2, located between the inlet / outlet 22 and the connecting joint 23. One end of the winding post 24 is provided with a first external thread, and the winding post 24 is threadedly connected to the first threaded through hole 26 through the first external thread. The end of the winding post 24 away from the first external thread is located near the cable passage 25. The winding post 24 and the housing 2 are threadedly connected, which facilitates the separation of the winding post 24 and the housing 2, so that after the cable and the connecting joint 23 are separated, the cable and the winding post 24 can be quickly taken out together.
[0036] A limiting post 3 is provided inside the wire passage 25. The limiting post 3 and the winding post 24 are coaxially arranged. The limiting post 3 and the housing 2 are slidably connected. The limiting post 3 is used to slide along the axial direction of the winding post 24.

[0038] Specifically, the limiting post 3 is a stud.
[0039] Specifically, the first threaded through hole 26 and the second threaded through hole 27 are coaxially arranged.
[0040] A rotating handle 31 is provided on the outside of the housing 2. Rotating the handle 31 drives the end of the connecting limiting post 3 away from the winding post 24. When taking out or winding the cable, rotate the handle 31 to move the limiting post 3 away from the winding post 24 and open the cable passage 25. When the cable is taken out or the cable is wound, rotate the handle 31 again to make the limiting post 3 abut against the winding post 24 and close the cable passage 25.
[0041] The cover 4 is a transparent cover with a clearance notch 41. When the transparent cover closes the inlet / outlet 22, the clearance notch 41 is used for cables to pass through.
[0042] Specifically, the cover 4 and the shell 2 are detachably fixedly connected by a snap fastener. The specific structure of the snap fastener is quite common and will not be described in detail here.
[0043] Specifically, the transparent cover includes two transparent plates, one end of which is hinged to the housing 2 via a hinge shaft, and the end of the transparent plate of the hinge housing 2 away from the hinge shaft is connected to one end of the other transparent plate; a clearance notch 41 is provided at the unconnected end of the transparent plate away from the hinge shaft.
[0044] The above description is only a preferred 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.
