Technical Field
[0001] This utility model relates to the field of socket wrench technology, and in particular to a socket wrench for engine high-pressure oil pipes. Background Technology
[0002] An engine high-pressure oil pipe socket wrench is a tool specifically designed for disassembling and assembling engine high-pressure oil pipe joints. Its head is typically a socket structure, which can precisely match the specifications of the high-pressure oil pipe joint, avoiding problems such as slippage and uneven force that may occur when using ordinary wrenches, thereby effectively protecting the joint threads and oil pipe from damage.
[0003] Existing technologies often have the following drawbacks: when the socket wrench is used in a narrow space, it is not easy for workers to directly move the tail of the socket wrench to disassemble the engine high-pressure oil pipe, thus increasing the difficulty of disassembling the engine high-pressure oil pipe joint.
[0004] Therefore, this utility model provides an engine high-pressure oil pipe socket wrench. Utility Model Content

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: an engine high-pressure oil pipe socket wrench, including a base 1, a socket body 2 fixedly connected to the surface of the base 1, an extension structure 3 provided on the surface of the base 1, and an adjustment structure 4 provided inside the socket body 2.
[0029] The specific settings and functions of its extension structure 3 and adjustment structure 4 will be discussed below.
[0030] Reference Figure 1-3 As shown in this embodiment: the extension structure 3 includes a limiting pin 31 fixedly connected to the base 1 on the side away from the socket wrench body 2. A rotating plate 32 is rotatably connected to the side wall of the limiting pin 31. A reserved groove 33 is provided on the inner side of the rotating plate 32. An L-shaped sliding plate 34 is slidably connected to the inner wall of the reserved groove 33. By setting the extension structure 3, the flexible rotation of the rotating plate 32 is facilitated, thereby facilitating the operation of the socket wrench in narrow spaces and improving the performance of the socket wrench to a certain extent. A rotating pin 35 is rotatably connected to the surface of the sliding plate 34. A handle 36 is fixedly connected to the end of the rotating pin 35. The handle 36 is connected to the sliding plate 34 through the rotating pin 35, and the handle 36 can be operated to achieve the twisting operation of the socket body 2. Several slots 39 are provided on the side wall of the limiting pin 31. An insert frame 37 is slidably connected inside the rotating plate 32. The size of the insert frame 37 is adapted to the size of the slots 39. The insert frame 37 is inserted into the slot 39 to lock and secure the rotated plate 32 after it has been twisted. The insert frame 37 is a rectangular ring structure, and a spring 38 is fixedly connected between the insert frame 37 and the rotated plate 32. The insert frame 37 is inserted into the slot 39 under the elastic force of the spring 38.
[0031] Reference Figure 1 and Figure 4As shown, specifically, the adjustment structure 4 includes a limiting plate 45 slidably connected inside the socket body 2. A clamping block 41 is fixedly connected to one end of the limiting plate 45 on the inner side of the socket body 2. A bolt 43 is threadedly connected inside the socket body 2. A storage groove 42 is provided on the inner side of the socket body 2, and the clamping block 41 is located inside the storage groove 42. By setting the adjustment structure 4, the adjustment of the inner space of the socket body 2 is facilitated, as is the disassembly of connectors of different sizes, further improving the usability of the socket body 2. A circular plate 44 is fixedly connected to the end of the bolt 43, and the circular plate 44 and the clamping block 41 are internally rotatably connected. The circular plate 44 at the end of the bolt 43 pushes the limiting plate 45, causing the clamping block 41 to slide along the inner wall of the socket body 2. The inner side of the clamping block 41 has a V-groove structure. The V-groove structure on the inner side of the clamping block 41 can tightly fit the polygonal contour of the connector.
[0032] Working principle: When it is necessary to disassemble or assemble a high-pressure oil pipe in a confined space, first pull the insert frame 37 out from the inside of the corresponding slot 39. At this time, the rotating plate 32 can be rotated to make it rotate around the limit pin 31, while the sliding plate 34 moves in the reserved slot 33 to adjust the position and angle of the handle 36. For example, if the connector is in a deep recessed position, the sliding plate 34 can be pulled out along the reserved slot 33 to extend the operating radius of the handle 36 and facilitate the application of force. After adjusting to the appropriate position, release the insert frame 37, and the insert frame 37 will be inserted by the elastic force of the spring 38. The insert slot 39 can lock and fix the rotating plate 32 after twisting, preventing the rotating plate 32 from shaking when force is applied. At this time, the handle 36 is connected to the slide plate 34 through the pivot pin 35, and the handle 36 can be operated to twist the socket body 2, avoiding the problem of inconvenience in applying force due to the narrow operating space. By setting the extension structure 3, it is convenient to flexibly turn the rotating plate 32 out for use, thereby facilitating the operation of the socket wrench in a narrow space and improving the performance of the socket wrench to a certain extent.
[0033] When dealing with high-pressure oil pipe joints of different sizes, rotating the bolt 43 causes it to move within the thread of the socket body 2. The circular plate 44 at the end of the bolt 43 pushes the limiting plate 45, causing the clamping block 41 to slide along the inner wall of the socket body 2. The V-groove structure on the inner side of the clamping block 41 can closely fit the polygonal contour of the joint. By tightening the bolt 43, the spacing of the clamping blocks 41 is reduced, thus achieving clamping and fixing of joints of different specifications. The storage groove 42 facilitates the flexible storage of the clamping block 41. The adjustment structure 4 facilitates the adjustment of the inner space of the socket body 2, making it easier to disassemble joints of different sizes and further improving the performance of the socket body 2.
