Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wrench tools, in particular to an F-shaped wrench. Background Art
[0002] There are various types and sizes of valves used in thermal power plants. To ensure the normal operation of these valves, maintenance and repair are essential. Traditional F-shaped wrenches are usually made of metal and are relatively heavy. This not only increases the workload of operators but also may cause slippage during operation due to the weight of the tool, thus threatening the personal safety of operators. In addition, due to the single size of traditional F-shaped wrenches, when dealing with valves of different sizes, it is often necessary to prepare wrenches of multiple sizes, which not only increases costs but also makes carrying and management very inconvenient.
[0003] At present, although some F-shaped wrenches on the market try to adapt to valves of different sizes by adding adjustable functions, there are still some problems in actual use. For example, the adjustment mechanism is complex and not easy to operate, or the strength of the wrench is insufficient due to the structural design, and it is easy to be damaged during high-torque operations. Summary of the Utility Model
[0004] Aiming at the deficiencies in the prior art, the utility model provides an F-shaped wrench. To achieve the above object, the utility model adopts the following technical solutions:
[0005] An F-shaped wrench includes a main rod, an extension arm, and a stethoscope. Two juxtaposed clamping arms are fixedly connected to the end of the main rod. A chute extending along the length direction of the main rod is formed on the top surface of the main rod. The extension arm is slidably connected in the chute. A tapered groove is formed in the main rod, and the tapered groove extends from the end of the main rod to the end where the clamping arms are provided. The stethoscope is clamped in the tapered groove, and the end of the stethoscope extends out of the tapered groove. A rubber earphone is provided at the end of the stethoscope.
[0006] Furthermore, the chute is a through groove, and the extension arm slides in both directions of the two ends of the main rod.
[0007] Furthermore, the extension arm is in a king shape, and the edges of the extension arm are rounded.
[0008] Furthermore, a plurality of convex ribs are provided on the top surface of the extension arm.
[0009] Furthermore, an annular groove is provided at a position near the end of the tapered groove, and the earphone is clamped in the groove.
[0010] Furthermore, an end cap is detachably installed at the end of the stethoscope.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. By optimizing the material selection and structural design, the F-type wrench of the present invention is lighter than the traditional wrench, reducing the burden on the operator and improving work efficiency;
[0013] 2. The stethoscope that is often used in combination is stored in the main rod of the wrench, which is convenient for storage and carrying;
[0014] 3. Through the design of the extension arm, the wrench can adapt to valves of different sizes, eliminating the need to replace different tools, greatly simplifying the operation process and reducing the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The following further describes the present utility model in conjunction with the drawings and embodiments:
[0016] Figure 1 It is a front view structural schematic diagram of an embodiment of the present utility model;
[0017] Figure 2 It is a left view structural schematic diagram of an embodiment of the present utility model.
[0018] In the above drawings: main rod 1, extension arm 2, stethoscope 3, clamping arm 4, sliding groove 5, conical groove 6, earphone 7, convex rib 8, groove 9, end cap 10. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following further describes the technical solutions in the present utility model in conjunction with the drawings and embodiments.
[0020] Please refer to Figure 1 、 Figure 2 As shown, an F-type wrench includes a main rod 1, an extension arm 2 and a stethoscope 3. Two juxtaposed clamping arms 4 are fixedly connected to the end of the main rod 1. A sliding groove 5 extending along the length direction of the main rod 1 is formed on the top surface of the main rod 1. The extension arm 2 is slidably connected in the sliding groove 5. A conical groove 6 is formed in the main rod 1, and the conical groove 6 extends from the end of the main rod 1 to the end where the clamping arms 4 are provided. The stethoscope 3 is clamped in the conical groove 6, and the end of the stethoscope 3 extends out of the conical groove 6. A rubber earphone 7 is provided at the end of the stethoscope 3.
[0021] In this embodiment, please refer to Figure 1 、 Figure 2 As shown, the sliding groove 5 is provided as a through groove, and the extension arm 2 slides in the directions of both ends of the main rod 1. The extension arm 2 can extend in the directions of both ends of the main rod 1, adapting to different operating environments and facilitating operation.
[0022] In this embodiment, please refer to Figure 1As shown, the extension arm 2 is arranged in a king shape, and the edges of the extension arm 2 are rounded. The operator can hold the recess of the extension arm 2, which is convenient for the operator to hold the extension arm 2 tightly without hurting the hand and is convenient for operation.
[0023] In this embodiment, please refer to Figure 2 As shown, a number of convex ribs 8 are arranged on the top surface of the extension arm 2. It is convenient for the operator to slide the extension arm 2 on the main rod 1 through the convex ribs 8, and it is convenient to use.
[0024] In this embodiment, please refer to Figure 2 As shown, an annular groove 9 is arranged at a position near the end of the tapered groove 6, and the earphone 7 is clamped in the groove 9. It avoids the dropping of the listening needle 3 and is convenient to use.
[0025] In this embodiment, please refer to Figure 2 As shown, an end cap 10 is detachably installed at the end of the listening needle 3. When using the listening needle 3, the end cap 10 is removed. When not using the listening needle 3, the end cap 10 is installed on the listening needle 3, so that the end cap 10 protrudes from the main rod 1, which is convenient for taking the listening needle 3.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
