Description

Technical Field

[0001] The present application relates to a shearing tool. Background Art

[0002] Cables are widely used in various communication and power transmission scenarios. When the cable laying environment is relatively harsh, armored cables are often used for laying and transmission. Armored cables are generally composed of PVC sheath, steel wire armor, XLPE insulation and PVC lining, which increase the mechanical strength of the cable and improve its corrosion resistance. Therefore, they are widely used. However, because armored cables have steel wire armor, the installation of cables and connectors, such as cable glands, is more cumbersome, mainly because it is inconvenient to cut the steel wire armor.

[0003] The traditional method mainly uses hacksaw and diagonal pliers for cutting, that is, first use diagonal pliers to bend each steel wire of the steel wire armor, and then use hacksaw to cut each bent steel wire. This not only easily causes uneven layers of the cut steel wires but also easily damages the cable.

[0004] Therefore, there is a need in the art for a cutting tool to improve the efficiency and quality of cutting operations, so as to facilitate cutting operations on cutting objects such as armored cables. Utility Model Content

[0008] In one or more embodiments of the shearing tool, the connecting assembly includes a bracket member connected to the sleeve, and the moving range of the bracket member moves from a first position to a second position. When the bracket member is located at the first position, the sleeve is located at the sleeve non-use position, and the sleeve is located in the space between the first handle portion and the second handle portion; when the bracket member is located at the second position, the sleeve is located at the sleeve use position.

[0009] In one or more embodiments of the shearing tool, the connecting assembly further comprises a first locking portion, and when the sleeve is located in the sleeve non-use position, the first locking portion locks the bracket member in the first position.

[0049] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and therefore the present application is not limited to the specific embodiments disclosed below.

[0051] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0052] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, upright, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present application. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

[0054] However, the dimensions or positional relationships of the components shown in the drawings are sometimes exaggerated for the purpose of clarifying the description. Furthermore, in the following description, for the same names and symbols, representing the same or homogeneous components, it is appropriate to omit their detailed description. Furthermore, the various elements constituting the present application may be in the form of a plurality of elements constituted by the same components so that one component serves as a plurality of elements, or conversely, it may be realized by a plurality of components sharing the function of a component. In addition, the contents described in some embodiments and implementation methods may also be utilized in other embodiments, implementation methods, etc. In addition, in this specification, "on" is not limited to the case where it is formed in contact with the upper surface, but also includes the case where it is formed separately on the upper surface, and is also used to include the meaning of the existence of an intervening layer between layers.

[0055] It should be understood that although the cutting object of the cutting tool introduced below is to cut the steel wire armor of the armored cable as an example, in order to improve the efficiency and quality of the cutting operation, the sleeve structure is adopted, so that the cutting tool can not only cut the outer PVC sheath of the armored cable, but also cut the armored steel wire, and can cut all the steel wire armor of the armored cable at the same length at the same time, so that the cut steel wire cuts are neat and avoid damage to the cable, thereby improving work efficiency and ensuring the quality of the cutting operation. However, it can be understood that the cutting object is not limited to the armored cable, and can also be other cutting objects.

[0056] refer to Figures 1 to 4As shown, in some embodiments, the shearing tool 100 includes a shearing portion 1, a sleeve assembly 2, and a handle portion 3. The shearing portion 1 may include a first shearing piece 11 and a second shearing piece 12, the first shearing piece 11 and the second shearing piece 12 can accommodate a shearing object 200, and the first shearing piece 11 and the second shearing piece 12 can be relatively close to each other to move to a shearing position 101 for shearing the shearing object 200. The first shearing piece 11 and the second shearing piece 12 can be moved from Figure 2 , Figure 3 The position shown is relatively close until it moves to Figure 1 as well as Figure 4 The shearing position 101 for shearing the shearing object 200 is shown. The handle portion 3 is connected to the shearing portion 1 and can be operated so that the first shearing piece 11 and the second shearing piece 12 are relatively close to or far away from each other. In some embodiments, the specific structure of the shearing portion 1 and the handle portion 3 can be similar to that of a traditional needle-nosed pliers, and the handle portion 3 includes a first handle portion 31 fixedly connected to the first shearing piece 11 and a second handle portion 32 fixedly connected to the second shearing piece 12. The first shearing piece 11 and the second shearing piece 12 are connected by a first pivot 4. After the first shearing piece 11 and the second shearing piece 12 are operated by the first handle portion 31 and the second handle portion 32, the first shearing piece 11 and the second shearing piece 12 can rotate around the first pivot 4, so that the first shearing piece 11 and the second shearing piece 12 are relatively close to each other to move to the shearing position 101 for shearing the shearing object 200. It can be understood that the cutting portion 1 generally has a shearing blade for shearing the shearing object 200, and the hardness of the shearing portion 1 is generally greater than the hardness of the shearing object. Taking the shearing object 200 as an example, the steel wire armor 202 of the armored cable 201, the hardness of the shearing portion 1 generally needs to be greater than the hardness of the steel wire of the steel wire armor 202, so that the shearing process is smoother.

[0057] refer to Figure 1 as well as Figure 2 As shown, the sleeve assembly 2 may include a sleeve 21 and a connection assembly 22 connected to the sleeve 21 ; the sleeve 21 can be driven by the connection assembly 22 to switch between a sleeve use position 211 and a sleeve non-use position 212 .

[0058] like Figures 2 to 4 As shown, it can be understood that Figure 4In order to clearly illustrate the structure of the armored cable 201, the structure of the sleeve 21 that will block the PVC lining 203 of the armored cable 201 is partially omitted. When the sleeve 21 is located at the sleeve use position 211, the sleeve 21 is located at the radial inner side of the shearing object 200, and the first shearing piece 11 and the second shearing piece 12 located at the shearing position 101 are located at the radial outer side of the shearing object 200, so that in the radial direction of the shearing object 200, the part of the shearing object 200 between the sleeve 21 and the first shearing piece 11 and the second shearing piece 12 can be cut. Specifically, taking the shearing object 200 as an armored cable 201 as an example, when the sleeve 21 is located at the sleeve use position 211, the sleeve 21 is located at the radial inner side of the steel wire armor 202 of the armored cable 201, and the first shearing piece 11 and the second shearing piece 12 located at the shearing position 101 are located at the radial outer side of the steel wire armor 202, and the portion of the steel wire armor 202 between the sleeve 21 and the first shearing piece 11 and the second shearing piece 12 can be cut. In some embodiments, the sleeve 21 is a retractable structure in the length direction of the sleeve, for example, it can be a multi-section retractable structure, or a steplessly adjustable retractable structure, and the length of the sleeve 21 can limit the length of the sheared steel wire armor, for example, the sleeve 21 can be flush with one end of the length direction of the steel wire armor, then the other end of the sleeve 21 limits the length of the sheared steel wire armor, and can also make the incision smooth. It can be understood that the sleeve 21 may be non-retractable but replaceable, and a plurality of sleeves 21 of different lengths may be provided as accessories of the shearing tool to meet the requirements for different shearing lengths.

[0059] Continue to refer Figures 1 to 4 As shown, in some embodiments, the specific structure of the connection component 22 driving the switching between the sleeve use position 211 and the sleeve non-use position 212 can be that the connection component 22 includes a bracket 221 connected to the sleeve 21, and the bracket 221 moves from the first position 2211 to the second position 2212. In some embodiments, the specific moving structure can be that the bracket 221 is connected to the second pivot 227, and the bracket 221 moves from the first position 2211 to the second position 2212. Such a structure is simple. However, it can be understood that the form of movement is not limited to the pivot rotation described above, for example, it can also be sliding, for example, the slide rail that limits the bracket 221 is constructed to provide a sliding structure.

[0060] When the bracket 221 is located at the first position 2211, the sleeve 21 is located at the sleeve non-use position 212, and the sleeve 21 is located in the space between the first handle portion 31 and the second handle portion 32; when the bracket 221 is located at the second position 2212, the sleeve 21 is located at the sleeve use position 211.

[0061] like Figure 2As shown, in some embodiments, the connection assembly 22 further includes a first locking portion 222, and when the sleeve 21 is located at the sleeve non-use position 212, the first locking portion 222 locks the bracket member 221 at the first position 2211. In some embodiments, the connection assembly 22 further includes a second locking portion 223, and when the sleeve 21 is located at the sleeve use position 211, the second locking portion 223 locks the bracket member 221 at the second position 2212. By locking the first locking portion and / or the second locking portion, the sleeve can be stably maintained at the set position in both the sleeve non-use position 212 and the sleeve use position 211, thereby improving the operating reliability of the shearing tool. Continue to refer to Figure 2 As shown, the specific structure for achieving the locking of the first locking part 222 and the second locking part 223 may be a structure of a spring and a locking member, and the locking member may be, for example, the first locking part 222 or the second locking part 223 having a rod 5, and the rod 5 switches the locking or unlocking state of the locking part. The rod 5 may be, for example Figure 2 The structure shown is similar to a pin, but is not limited thereto. With the structure described above, the sleeve 21 can be easily switched between the sleeve use position 211 and the sleeve non-use position 212, further improving the efficiency of the shearing operation.

[0062] Continue to refer Figures 2 to 4 As shown, in some embodiments, the specific structure of the connecting assembly 22 may further include a base 224, the base 224 is located in the space between the first handle portion 31 and the second handle portion 32, a side wall 225 protrudes from the base 224 and correspondingly accommodates the sleeve 21 located in the sleeve non-use position 212; a spring member 226 is provided in the space limited by the side wall 225 and the base 224, and the spring member 226 is used to connect with the sleeve 21 located in the sleeve non-use position 212. In this way, when the sleeve 21 needs to be driven, the spring member 226 can play the role of popping up the bracket member 221, further facilitating the operator to perform the shearing operation.

[0063] In summary, combined Figures 1 to 4 As shown, when cutting the armored cable 201, the cutting tool 100 can be opened first, that is, the first cutting piece 11 and the second cutting piece 12 are relatively far apart, so that the armored cable 201 is placed on the cutting blade of the cutting tool 100, and the PVC sheath of the armored cable 201 is cut off, and then the armored steel wire 202 of the armored cable 201 is cut, and the sleeve 21 is extended, and the first locking part 222 is unlocked, so that the bracket member 221 is no longer locked in the first position 2211. In addition, the pop-up of the bracket member 221 can be mainly based on the action of the base 224 and the spring member 226. Then, the sleeve 21 is placed in the position between the first cutting piece 11 and the second cutting piece 12, and the bracket will be locked by the second locking part 223, thereby locking the bracket member 221 in the second position 2212, as shown in FIG. Figure 4 As shown, the sleeve 21 is located at the PVC lining 203 on the radial inner side of the steel wire armor 202 of the armored cable 201, the first shearing piece 11 and the second shearing piece 12 located at the shearing position 101 are located on the radial outer side of the steel wire armor 202, and the portion of the steel wire armor 202 between the sleeve 21 and the first shearing piece 11 and the second shearing piece 12 can be cut. When the shearing portion 1 is located at the shearing position 101, the steel wire armor 202 can be cut. It can be understood that

[0064] The beneficial effect of the cutting tool introduced in the above embodiment is that, by adopting the structure of the sleeve, the cutting tool can not only cut the outer PVC sheath of the armored cable, but also cut the armored steel wire. All the steel wire armor of the armored cable can be cut to the same length at the same time, so that the cut steel wires are neat and avoid damage to the cable, thereby improving work efficiency and ensuring the quality of the cutting operation.
