Description

Technical Field

[0001] The utility model belongs to the technical field of borescopes, and in particular relates to a borescope snake head structure. Background Art

[0002] In aerospace, especially in aircraft engine and civil aviation engine inspection applications, there is a remote visual inspection instrument that is good at using "holes" to "peek inside" the engine cavity. Perhaps you have guessed that it is an industrial endoscope that requires a borescope. The borescope cleverly uses the imaging component at the front end of the probe to present its internal conditions to the borescope personnel in the form of real-time visual images without disassembling the engine, assisting them in accurately understanding the engine status and formulating wise monitoring or maintenance strategies. While ensuring safety, it fully utilizes the engine safety margin and saves maintenance costs.

[0003] In the prior art, a borescope generally includes an instrument body, one end of which is fixedly connected to an electric wire, and one end of which is fixedly connected to a snake head. The borescope operation is performed through the snake head structure to help workers visualize the internal environment.

[0004] However, when the above device is in use, the snake head is easily damaged by friction or collision with the interior, requiring staff to inspect and replace the snake head. However, the snake head is generally fixed to the wire by welding, which is not convenient for staff to disassemble. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and proposes a borescope snake head structure, which has the advantages of being easy to disassemble by the staff and facilitating the operation of the staff.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A borescope snake head structure, comprising a borescope body, one side of the borescope body is fixedly connected with an electric wire, one side of the electric wire is provided with a snake head body, one side of the snake head body is provided with a fixing mechanism, and one side of the borescope body is provided with a placing mechanism;

[0008] The fixing mechanism includes a fixing ring fixedly connected to the surface of one end of the electric wire close to the snake head body, the end of the snake head body close to the electric wire is rotatably connected to a mounting ring through a bearing, the inner wall of the mounting ring is connected to the outer wall of the fixing ring by a threaded connection, one end of the electric wire is fixedly connected to a male plug, and one end of the snake head body is fixedly connected to a female plug, the male plug and the female plug are plugged in, and the male plug is inserted into the female plug, so that the snake head body can be connected to the borescope body through the electric wire, and the mounting ring is rotated when the male plug and the female plug are connected. After the male plug and the female plug are stably plugged in, the connecting rod is slid into the positioning groove to fix the snake head body, and when the equipment is placed, the snake head is inserted into the placement port between the two limit blocks to fix the snake head body. Therefore, it is convenient for the staff to disassemble and achieve the effect of facilitating the operation of the staff.

[0009] A connecting groove is provided at the top and bottom of one end of the fixing ring, and a connecting rod is slidably connected to the inner wall of the connecting groove. The connecting rod is in a U-shaped structure and contacts one end of the fixing ring. The U-shaped structure design facilitates the sliding operation of the connecting rod in the inner wall of the connecting groove and the inner wall of the positioning groove, thereby fixing the mounting ring.

[0010] A connecting spring is fixedly connected to the inner wall of one end of the connecting groove, and the connecting spring is fixedly connected to one end of the connecting rod. The setting of the connecting spring can drive the connecting rod to reset, so that the connecting rod can be stably placed in the positioning groove.

[0011] A positioning groove is provided at one end of the mounting ring, and a sliding fit is formed between the inner wall of the positioning groove and the connecting rod. The setting of the positioning groove can limit the connecting rod, so as to fix the mounting ring by cooperating with the inner wall of the connecting groove to limit the connecting rod.

[0012] The placement mechanism includes a placement plate fixedly connected to the outer wall of the borescope body, a placement opening is provided on the top of the placement plate, a sliding fit is formed between the inner wall of the placement opening and the snake head body, and the setting of the placement plate allows the snake head body to slide into the placement opening, so that the snake head body can be placed.

[0013] Limiting grooves are provided on the inner walls at both ends of the placement opening, and a limiting spring is fixedly connected to the inner wall of the limiting groove at one end, and a limiting block is fixedly connected to one end of the limiting spring. A sliding fit is formed between the limiting block and the inner wall of the limiting groove. The setting of the limiting block can slide in the inner wall of the limiting groove, and the limiting spring can be squeezed at this time. After the snake head body is located in the placement opening, the limiting block can fix the snake head body under the pressure of the limiting spring.

[0014] One end of the limit block is in an arc shape, and the center of the arc surface of the limit block is far away from the limit groove. The design of the arc structure can increase the contact area between the limit block and the snake head body, thereby fixing the snake head body.

[0015] The beneficial effects of the utility model are:

[0016] 1. The borescope snake head structure device can be fixed to the fixing ring by rotating the mounting ring, and relative displacement occurs between the mounting ring and the fixing ring. After the male plug and the female plug are stably plugged in, the connecting rod is slid into the positioning groove to fix the snake head body. Therefore, it is convenient for the staff to disassemble and achieve the effect of facilitating the operation of the staff.

[0017] 2. The borescope snake head structure device can slide in the inner wall of the limit groove through the limit block, and the limit spring can be squeezed at this time. After the snake head body is located in the placement opening, the limit block can fix the snake head body under the pressure of the limit spring. The limit block with an arc-shaped structure can increase the contact area between the limit block and the snake head body, so that the snake head body can be fixed.
