Description

Technical Field

[0001] This utility model relates to the field of flat file technology, and in particular to a flat file handle that can be flexibly detached. Background Technology

[0002] In industries such as metal, wood, or plastic processing, the frequent use of flat files has become a key factor in the development of these industries. Therefore, optimizing the innovative design of flat files and improving employee comfort and efficiency have become key tasks for these industries.

[0003] Flat files, as a common metalworking tool, have a wide range of applications and are suitable for industries such as precision machining and surface treatment, including processing metals, wood, and plastics. They are made of carbon tool steel and are classified according to the number of teeth on each 10mm long file surface, including coarse files (4-12 teeth), fine files (13-24 teeth), and smooth files (30-40 teeth). Currently, flat files sold on the market are divided into ordinary flat files and flat files with handles.

[0004] Ordinary flat files have a strip-shaped end, which makes the experience of employees holding the file poor and reduces efficiency. When filing large flat surfaces or filing certain angled positions in the processing of metal, wood, plastic and other fields, the design of ordinary flat files requires the filing surface to be placed flat on the board, which is not conducive to surface filing. In addition, due to the unstable grip, the strip-shaped end of ordinary flat files can easily cause secondary damage to the surface of the board during filing, increasing the labor intensity of employees and reducing the efficiency of operation.

[0005] While flat files with handles improve the comfort of employees holding the end of the flat file, they also have drawbacks such as high purchase costs for the handles, low reusability of the flat file handles, and gaps between the flat file handle and the filing surface when filing large flat surfaces or filing at certain angles due to the handle height design, which is not conducive to fine surface processing. Therefore, a flat file handle that can be flexibly detached is designed to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a detachable flat file handle, which solves the problem that flat files are inconvenient for repairing plates in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0008] A detachable flat file handle includes a grip, a threaded connecting rod, a connecting rod nut, a movable cover plate, a fixed cover plate, and locking bolts. The right end of the grip is vertically fixed with a threaded connecting rod, and a connecting rod nut is threaded onto the threaded connecting rod. The movable cover plate passes through the threaded connecting rod, and a groove is laterally formed on the upper surface of the movable cover plate. The bottom of the threaded connecting rod is fixed with a fixed cover plate, and locking bolts are threaded onto both ends of the movable cover plate.

[0009] Furthermore, both the movable cover plate and the fixed cover plate are inverted L-shaped.

[0010] Furthermore, the bottom horizontal heights of the movable cover plate and the fixed cover plate are the same, and the upper width of the movable cover plate is greater than the upper width of the fixed cover plate.

[0011] Furthermore, the width of the groove is equal to the diameter of the threaded connecting rod, and both ends of the groove are semi-circular, with the threaded connecting rod passing through the groove.

[0012] Furthermore, a rubber gasket is fitted between the bottom of the connecting rod nut and the upper surface of the movable cover plate.

[0013] Furthermore, the end of the locking bolt is provided with a frosted layer.

[0014] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0015] This invention facilitates the fixing of flat files of different sizes. After the flat file handle is tightened, employees can hold the handle to complete large-area fine surface processing and surface treatment in industries such as metal, wood or plastic processing, as well as file repair work at special angles and positions.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] See Figure 1-4 A detachable flat file handle includes a handle 1, a threaded connecting rod 2, a connecting rod nut 3, a movable cover plate 4, a fixed cover plate 5, and locking bolts 6. The right end of the handle 1 is vertically fixed with a threaded connecting rod 2, and the threaded connecting rod nut 3 is threaded onto the threaded connecting rod 2. The movable cover plate 4 passes through the threaded connecting rod 2, and a sliding groove 401 is horizontally opened on the upper surface of the movable cover plate 4. The bottom of the threaded connecting rod 2 is fixed with a fixed cover plate 5, and locking bolts 6 are threaded onto both ends of the side of the movable cover plate 4.

[0025] In actual use, pick up an ordinary flat file, insert it between the movable cover plate 4 and the fixed cover plate 5, and push the movable cover plate 4 and the fixed cover plate 5 laterally. The threaded connecting rod 2 slides laterally in the slide groove 401. The movable cover plate 4 cooperates with the fixed cover plate 5 to tighten the side of the flat file. Then tighten the connecting rod nut 3 so that the connecting rod nut 3 is close to the upper surface of the movable cover plate 4. The movable cover plate 4 cooperates with the fixed cover plate 5 to complete the first step of tightening the flat file. Then tighten the locking bolt 6 on the side of the movable cover plate 4. The locking bolt is lower than the side of the flat file to complete the second step of tightening the flat file, which is convenient for fixing flat files of different sizes. After tightening, the employee can hold the handle 1 to complete large-area flat fine processing and surface treatment in the processing of metal, wood or plastic industries, as well as file work at special angles and positions.

[0026] When the filing function of the bottom surface of the flat file fails, the flat file can be replaced. Use a tool to loosen the locking bolt 6 on the side of the movable cover plate 4, and then loosen the connecting rod nut 3 on the threaded connecting rod 2. The flat file can then be removed from between the movable cover plate 4 and the fixed cover plate 5. Then flip the flat file over and install it with the unfiled side facing the bottom to achieve the effect of reusability.

[0027] In this embodiment, both the movable cover plate 4 and the fixed cover plate 5 are inverted L-shaped, which makes it convenient for the movable cover plate 4 to cooperate with the fixed cover plate 5 to clamp the side of the flat file.

[0028] In this embodiment, the bottom horizontal heights of the movable cover plate 4 and the fixed cover plate 5 are the same, and the upper width of the movable cover plate 4 is greater than the upper width of the fixed cover plate 5, ensuring that the bottoms of the movable cover plate 4 and the fixed cover plate 5 are at the same horizontal height, which facilitates clamping the flat file.

[0029] In this embodiment, the width of the groove 401 is equal to the diameter of the threaded connecting rod 2, and the two ends of the groove 401 are semi-circular. The threaded connecting rod 2 passes through the groove 401, which facilitates the sliding of the threaded connecting rod 2 along the groove 401.

[0030] In this embodiment, a rubber gasket is sleeved between the bottom of the connecting rod nut 3 and the upper surface of the movable cover plate 4 to increase the friction between the connecting rod nut 3 and the movable cover plate 4, thereby increasing the stability of the connecting rod nut 3 when it is fixed to the movable cover plate 4.

[0031] In this embodiment, the end of the locking bolt 6 is provided with a frosted layer to increase the friction when the locking bolt 6 contacts the side of the flat file when it is tightened, thereby increasing the stability of the flat file.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
