Description

Hand tool anti-drop structure

This creation relates to the field of carrying hand tools, in particular to an anti-dropping structure for hand tools.

The known hand tools are convenient for a user to hold and perform required tasks, such as tightening or loosening a fastener. During work, the hand tools may fall to the ground. Although, the user bends over or squats down and can pick up hand tools to continue working. However, for technicians engaged in high-altitude operations, it is a waste of time to travel between heights and the ground. What's more, returning to the surface just to pick up hand tools is obviously putting the cart before the horse.

Thus, an anti-falling equipment came into being. The known anti-drop equipment usually refers to two key rings combined with two ends of a rope of a predetermined length. One of the two keyrings is directly or indirectly buckled on the user's body, and the other keyring is indirectly buckled with the hand tool through a strap.

In view of this, the author of this case developed a hand tool anti-drop structure, the main purpose is to use a combination method to directly connect the rope to the hand tool, omit unnecessary straps, save time for assembly and disassembly, and achieve the function of preventing falling.

In order to achieve the above-mentioned purpose, the anti-fall structure of the present creation includes: a handle; a rod arranged on the side of the outer side of the handle; and a hooking space exists between the rod and the surface of the handle.

In this way, the anti-fall structure of the present creation combines the rod with the hand tool, connects the user and the hand tool with a rope, omits the prior art strap, saves time for assembly and disassembly, and achieves the function of preventing falling.

In order to make the above-mentioned purpose, features and advantages of this creation more simple and understandable, one or more embodiments are given below in detail with the accompanying drawings.

Figure 1 is a perspective view illustrating that the first embodiment of the hand tool 10 is to install a set of operating elements 12 on both ends of a handle 20. In the figure, the two ends of the handle 20 are respectively coupled with a coupling member 14, and the overlapping part of the coupling member 14 and the operating member 12 is passed through by a shaft 16. Therefore, the handle 20 can lock or loosen the fastener through the operating member 12. Specifically, the set of operating elements 12 has openings of different specifications, and each opening covers a suitable fastener, such as a nut or a screw head. Therefore, the hand tool 10 is equivalent to a torque wrench.

In some embodiments, the operating member 12 may be a ring with a hexagon socket or a sleeve with a hexagon socket.

FIG. 2 is a plan view, showing that a rod 22 is arranged on the outer side of the handle 20, and a hooking space 24 exists between the rod 22 and the surface of the handle 20. The rod 22 cooperates with the hooking space 24 to form a fall prevention structure, which is used on the hand tool 10.

Figure 3 is a cross-sectional view showing an enlarged anti-fall structure. In the figure, the side of the handle 20 has a concave portion 28, which is a concave curved surface. The distance from the lowest point of the concave curved surface to the rod 22 forms a half-moon space, which is the range of the above-mentioned hooking space 24.

Wherein, the handle 20 is a housing 21 which includes a rigid layer 25 with a recess 28. At this moment, the two ends 26 of the rod 22 are embedded in the rigid layer 25, so the rod 22 is located at the opening of the recess 28.

The rigid layer 25 referred to here generally refers to a rigid material that is not easily flexed, and is enclosed in a single-layer structure. As for an installation space 27 in the rigid layer 25 and which components or structures are assembled in the installation space 27, it has nothing to do with this case, so it will not be discussed and repeated.

In addition, the housing 21 also has a flexible layer 23 that covers a part of the rigid layer 25 without shielding the rod 22 and the recess 28, and naturally does not affect the hooking space 24.

Fig. 4 is a cross-sectional view to further describe the use state of the anti-fall structure. The rod 22 is connected to a rope 32 drawn in dashed lines. In the figure, a hook 30 is coupled to one end of the rope 32, and the hook 30 hooks the rod 22. The other end of the rope 32 is connected to a user (not shown) to prevent the handle 20 from falling together with the hand tool.

Fig. 5 is a plan view showing the second embodiment of the hand tool. Its structure is substantially the same as that of the first embodiment. The difference is that the handle 20 has an additional set of raised portions 29.

From the enlarged view of FIG. 6, the group of raised portions 29 is provided at a portion where the rigid layer 25 is not covered by the flexible layer 23, and there are recesses 28 between the group of raised portions 29. At this moment, the two ends 26 of the rod 22 are embedded in the protruding part 29, so the rod 22 is still at the opening of the recess 28, relatively expanding the range of the hooking space 24.

Figure 1 is a perspective view of the first embodiment of the hand tool. Figure 2 is a plan view of the grip of the first embodiment, showing the fall prevention structure. Figure 3 is an enlarged cross-sectional view of the anti-drop structure of Figure 2. Fig. 4 is a cross-sectional view taken along the line A-A in Fig. 3, and the broken line indicates the hook. Figure 5 is a plan view of the handle of the second embodiment of the hand tool, showing the anti-drop structure. Figure 6 is an enlarged view of the fall prevention structure of Figure 5.
