Description

Technical Field

[0001] This utility model belongs to the technical field of propeller torque adjustment tools, and more specifically, it relates to a propeller torque adjustment tool. Background Technology

[0002] The torque adjustment tool for propellers is mainly used to adjust the angle (i.e., angle of attack) of the propeller blades to change the propeller's thrust and rotational speed, thereby improving aircraft performance. This tool is typically used in adjustable propeller systems and can adjust the propeller's operating state in real time according to flight conditions (such as flight speed, engine power, etc.) to optimize fuel efficiency, increase thrust, or reduce noise.

[0003] Some propeller torque adjustment tools do not monitor the rotation angle during adjustment, which can easily increase errors during rotation.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a propeller torque adjustment tool in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a propeller torque adjustment tool, which is achieved by the following specific technical means: A torque adjustment tool for a propeller includes a handle and an adjustment wrench. A slot is provided through one side of the handle, and an adjustment rod is inserted into the slot. The adjustment wrench is installed on one side of the adjustment rod. A connecting plate is detachably installed on the other end of the adjustment rod by bolts. An annular seat is installed on one side of the connecting plate by a bracket. An angle scale is rotatably installed on the bottom end of the annular seat by a bearing seat.

[0006] Furthermore, a pointer is mounted on one side of the adjusting wrench.

[0007] Furthermore, the surface of the adjusting rod is provided with several threaded grooves at equal intervals.

[0008] Furthermore, a fixing bolt matching the size of the threaded groove is installed at the bottom end of the handle.

[0009] Furthermore, the angle scale is made of a magnetic block. Compared with the prior art, the present invention has the following beneficial effects: The propeller torque adjustment tool of this utility model, through the combined use of a handle, adjusting wrench, slot, adjusting rod, connecting plate, annular seat, angle scale, pointer, threaded groove and fixing bolt, facilitates the observation of the rotation angle of the torque adjustment tool by the combination of the annular seat, angle scale and pointer, thereby improving the adjustment accuracy of the propeller torque adjustment tool.

[0013] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0014] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0016] As attached Figure 1 To be continued Figure 2 As shown: This utility model provides a torque adjustment tool for a propeller, including a handle 1 and an adjustment wrench 2. The adjustment wrench 2 adopts the prior art (such as the adjustment structure disclosed in patent application number CN202322497834.5). A slot 3 is provided through one side of the handle 1, and an adjustment rod 4 is inserted into the slot 3 for fixing the adjustment wrench 2 to the handle 1. The adjustment wrench 2 is installed on one side of the adjustment rod 4. A connecting plate 5 is detachably installed on the other end of the adjustment rod 4 by bolts. An annular seat 6 is installed on one side of the connecting plate 5 by a bracket. An angle scale 7 is rotatably installed on the bottom end of the annular seat 6 by a bearing seat.

[0017] One side of the adjusting wrench 2 is equipped with a pointer 8, which makes it convenient for staff to observe the rotation angle of the adjusting wrench 2.

[0018] Among them, the surface of the adjusting rod 4 is provided with several threaded grooves 9 at equal intervals.

[0019] The bottom of the handle 1 is equipped with a fixing bolt 10 that matches the size of the threaded groove 9. By sliding the adjusting rod 4 in the slot 3 and fixing it with the fixing bolt 10, the position of the adjusting wrench 2 can be adjusted according to actual usage needs.

[0020] The angle dial 7 is made of magnetic material, which allows it to be attracted to the propeller adjustment position, making it convenient for staff to use. If it is not easy to attract the propeller adjustment position, staff can press the angle dial 7 directly onto the adjustment position by hand.

[0021] The working principle of this embodiment is as follows: When using the torque adjustment tool for this propeller, the operator first inserts the adjustment rod 4 into the slot 3 and fixes the adjustment rod 4 with the fixing bolt 10. Then, the angle scale 7 of a suitable size is fixed to one side of the adjustment rod 4 through the connecting plate 5, and the propeller adjustment position is passed through the adjustment wrench 2. At this time, the angle scale 7 is in close contact with the lower surface of the propeller adjustment position. The operator can fix the angle scale 7 by magnetic attraction or manual pressing, and then adjust the propeller by adjusting the wrench 2. The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
