Description

Technical Field

[0001] The invention relates to the technical field of hardware tools, and in particular to a portable integrated wire tube nut wrench. Background Art

[0002] As society's requirements for the safety of power infrastructure increase, cable installation methods are also constantly improving. Generally, cables are required to be routed through conduits. During the installation of conduits, many accessories often need to be fixed with nuts, which makes wrenches an indispensable installation tool. However, since the nuts corresponding to different accessories may be of different sizes, workers often need to carry a variety of different types of wrenches, and most wrenches are made of metal and are heavy, which greatly increases the burden on workers. Especially when installing large conduit nuts, the large wrenches that need to be used are large in size and heavy in weight. The length may exceed 400 mm and the weight is as high as 3 kg or more, making it extremely inconvenient to carry, especially in scenarios with special installation environments (such as high altitudes, confined spaces, etc.). This problem is particularly prominent.

[0003] The universal nut wrenches currently available on the market usually consist of a wrench body and a series of sleeves, each sleeve being designed for a specific type of nut. This means that although the wrench body can be shared, the staff still needs to carry a large number of sleeves and replace different sleeves according to actual needs. This approach has limited effect in reducing the weight of the carrying tool. In addition, although some adjustable universal wrenches can adapt to a variety of sizes, they may not be able to accurately adapt to nuts or bolts like fixed-size wrenches, and may sometimes even cause slippage. Adjustable wrenches contain more moving parts, such as screws, gears or hinges, which are more susceptible to wear or damage after long-term use. It can be seen that the nut wrenches in the prior art all have some shortcomings. Therefore, the present application aims to provide a lightweight integrated wire tube nut wrench. Summary of the invention

[0004] The object of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a portable integrated wire tube nut wrench.

[0005] The technical solution of the present invention is: a portable integrated wire tube nut wrench, comprising a main body, a fixing hole designed on the main body, the fixing hole is used to install an axle pin, and the axle pin remains perpendicular to the surface of the main body after installation; the centers of the fixing holes are distributed on a plurality of concentric circles; and a plurality of fixing holes are distributed on each circle; a plurality of axle pins are installed in the fixing holes on the same circle, so that the plurality of axle pins form a circle to form a fence structure of corresponding size; the fence structure just engages with nuts of corresponding models, so as to be used to realize the tightening and loosening operations of wire tube nuts of corresponding models.

[0006] Furthermore, the shaft pin is provided with a threaded end matching the fixing hole, and the threaded end cooperates with the locking nut after passing through the fixing hole, so that the shaft pin is detachably fixed to the main body.

[0007] Furthermore, the edges of the concentric circles are marked in an obvious manner to facilitate user observation, so that the axle pin can be quickly installed in the target fixing hole; for example, in the fixing holes on the same circle.

[0008] Furthermore, the method for marking the edges of the concentric circles includes depicting the edges of the concentric circles with lines of different colors or different line types.

[0009] Furthermore, six fixing holes are evenly distributed on each concentric circle.

[0010] Furthermore, the main body is in the shape of a long strip, and fixing holes are provided at both ends of the main body.

[0011] Furthermore, one end of the main body is also provided with a safety rope hole, which is used to hang a safety rope.

[0012] Furthermore, the thickness of the main body is greater than the diameter of the axle pin, and the width of the main body is adapted to the length of the axle pin.

[0013] Furthermore, a receiving groove is provided on the side of the main body, and the receiving groove is used to receive the shaft pin and its locking nut. At the same time, the receiving groove further reduces the weight of the main body.

[0014] Furthermore, there are multiple accommodating grooves, and each accommodating groove can store a corresponding shaft pin and its locking nut.

[0015] Furthermore, there are 6 receiving grooves, the diameter of which is adapted to the diameter of the axle pin, and a friction layer is provided on the surface of the receiving groove or the axle pin, so that a certain friction resistance needs to be overcome when the axle pin is inserted into or pulled out of the receiving groove; to ensure that the axle pin can be stably fixed in the receiving groove during normal storage (without other external forces).

[0016] Furthermore, the friction layer may be a rubber layer, and the rubber layer may be arranged on the outer surface of the shaft pin, or on the inner wall of the accommodating groove.

[0017] Furthermore, the accommodating groove runs through the width direction of the main body, so that the axle pin can enter and exit the accommodating groove from both sides of the main body, which is particularly convenient for removing the axle pin. Because when it is to be removed, the end of the axle pin can be pushed from the opening on one side of the accommodating groove, so that the axle pin extends from the opening on the other side of the accommodating groove. The user can hold the extended part and pull out the axle pin directly and completely.

[0018] Furthermore, in addition to the threaded connection, other detachable connection methods may be used between the shaft pin and the main body, such as a snap-on structure.

[0019] Furthermore, the main body can be made of aluminum alloy, anodized, and anti-corrosive and anti-slip; the axle pin is made of 304 stainless steel, which is rust-proof and has high strength, and can fully meet the operating conditions for wire tube nuts.

[0020] Furthermore, the shaft pin is cylindrical. Of course, the shaft pin can also be designed into other shapes, such as a triangular prism, according to actual needs.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the nut wrench in the present invention only includes a main body and a small number of axle pins and their locking nuts (for example, 6 sets), and a plurality of fixing holes are arranged on the main body. The fixing holes are pre-designed so that after the axle pins are installed on the corresponding fixing holes, a plurality of fence structures of different sizes can be formed, and the fence structures of different sizes are matched with nuts of corresponding models, that is, the present invention can be combined at will to realize the functions of wrenches of different specifications; at the same time, the wrench of the present invention itself is light in weight, small in size, low in cost, simple to switch, and easy to carry.
