[0020] The utility model will be further explained in detail in connection with the drawings and specific embodiment, and is not to limit the implementation scope of the utility model to this.
[0021] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1-5 As shown, this embodiment of a multifunctional inspection hammer includes a hammer head 1 and a hammer handle 2. One end of the hammer handle 2 is fixedly connected to the hammer head 1, and the other end is provided with a measuring unit 3. The measuring unit 3 includes a connecting seat 31 and a measuring scale 32. One end of the connecting seat 31 is connected to the measuring scale 32, and the other end is a flat pry plate 33. The hammer handle 2 is provided with a cavity for accommodating the measuring scale 32. Both ends of the connecting seat 31 are detachably connected to the hammer handle 2. This utility model provides a connecting seat 31 at the end of the hammer handle, and both ends of the connecting seat are respectively provided with a pry plate 33 for realizing the function of a pry bar and a hammer measuring scale 32 for realizing the measurement function. When the measuring ruler 32 is located inside the cavity of the hammer handle 2, the flat pry bar 33 is located at the end of the hammer handle. This allows the hammer handle to function as a pry bar, facilitating the replacement of brake shoes for railway freight cars. Furthermore, the measuring ruler 32 is enclosed within the hammer handle 2 via the connecting seat 31, which not only conceals the measuring ruler 32 but also protects it. When the measuring ruler 32 is needed, it is removed from the hammer handle 2, or connected to the end of the hammer handle 2 via the connecting seat 31, with the flat pry bar 33 located inside the cavity of the hammer handle 2, allowing for measurement using the measuring ruler 32.
[0024] The inner wall of the hammer handle 2 is provided with a groove 21. After the measuring ruler 32 is inserted into the hammer handle 2, both sides of the measuring ruler 32 are located in the groove 21, which fixes the measuring ruler 32 and prevents the measuring ruler 32 from deforming when it is struck.
[0025] The two ends of the connecting seat 31 are connected with the hammer handle 2 through threads or screws, so that the two ends of the connecting seat 31 are connected with the end of the hammer handle 2, when the threads are used, the measuring scale 32 is rotationally connected with the connecting seat 31, or the measuring scale 32 is rotationally connected with the connecting seat 31 through a support, after the measuring scale 32 is inserted into the cavity of the hammer handle 2, the connecting seat 31 is connected with the hammer handle 2 firmly by rotating and tightening.
[0026] One embodiment is that the thickness of the measuring scale 32 gradually increases from the free end to the fixed end, when the gap is measured, the measuring scale 32 is inserted into the gap to be measured, the gap value is measured by the thickness number at the position of the measuring scale 32, or a mark is made on the measuring scale 32, and the thickness value of the measuring scale 32 at the position is measured by using other measuring tools such as a vernier caliper, so that the gap value is measured.
[0027] The measuring scale 32 and the hammer handle 2 are provided with scales, the measuring scale 32 can measure the depth of a groove, and after the measuring scale 32 is connected with the hammer handle 2 through the connecting seat 31, the length of the measuring tool is lengthened, so that the depth of a deep groove can be measured.
[0028] Another embodiment is that the measuring scale 32 includes a plurality of pieces with different thicknesses, the connecting seat 31 is rotationally connected with a support inside, and the pieces are rotationally connected with the support through pins. When used, the connecting seat 31 is separated from the hammer handle 2, and the pieces with different thicknesses can be used alone or stacked, so that the size of the gap is measured. After use, the pieces can be placed in the hammer handle 2, and the pieces can be protected to prevent wear.
[0029] One end of the hammer head 1 is cylindrical, and the other end is conical, because the brake shoe is located inside the railway wagon, the length of the cylindrical section of the hammer head is 20 mm, a worker holds the hammer handle 2, the hammer head is inserted into the railway wagon, and the thickness of the brake shoe of the railway wagon is conveniently judged according to the cylindrical section of the hammer head, whether the thickness is lower than the limit value of 20 mm. The length of the hammer head is 75 mm, and whether the mutual hook difference of the railway wagon exceeds the limit value of 75 mm can be judged according to the length of the hammer head.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not used to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
