Description

Technical Field

[0001] The present invention belongs to the technical field of electric power fittings, and specifically refers to an NXJG wedge-type tension clamp. Background Art

[0002] In the field of power transmission, tension clamps are important hardware used to fix conductors on non-linear poles and towers. Their performance is directly related to the safe and stable operation of the power system.

[0003] Traditional tension clamps have many problems during use. The existing tension clamps are open on one side and are affected by external factors such as wind force and the weight of the conductor during actual use. Long-term use can cause product deformation, abnormal resistance temperature rise, insufficient grip, and conductor slippage or even falling off, resulting in power outages and casualties. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides the NXJG wedge-type tension clamp, which uses two sets of mutually interlocking wedge blocks and a sliding wedge block, and utilizes the principle of wedge structure to generate a strong clamping force to firmly fix the wire in the clamping hole. This design can effectively prevent the wire from slipping or falling off under the influence of various environmental factors, greatly improving the safety and stability of power transmission.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: NXJG wedge-type tension clamp, including a wedge-type clamp body and two groups of wedge blocks that are interlocked with each other, the wedge-type clamp body is covered on the outside of the two groups of wedge blocks, the wedge blocks and the wedge clamp body are arranged to slide relative to each other, and a wire clamping hole is formed between the wedge blocks. The cross-section of the wedge-type clamp body is U-shaped, and the open end of the wedge-type clamp body is slidably connected with a wedge block, which is arranged on the two groups of wedge blocks. The wedge block is arranged in an isosceles trapezoidal structure. After the wire is installed, the wedge block is knocked by a wooden hammer and the wedge block moves to the other end, thereby clamping the wire to prevent slipping or falling off.

[0006] As a preferred technical solution of the present invention, two outer side walls of the wedge-shaped wire clamp body are hinged with pull plates, and two groups of pull plates are symmetrically located on both sides of the wedge-shaped wire clamp body.

[0007] As a preferred technical solution of the present invention, a fastening bolt is passed through the ends of the two groups of pull plates away from the wedge-shaped wire clamp body.

[0008] As a preferred technical solution of the present invention, bosses are evenly arranged on the outer side wall of the wedge-shaped wire clamp body.

[0009] As a preferred technical solution of the present invention, anti-slip patterns are provided on the opposite side walls of the two groups of wedging blocks.

[0010] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects:

[0011] 1. By setting up two sets of mutually interlocking wedge blocks and sliding wedge blocks, when the wedge blocks and wedge blocks are struck with a wooden hammer, they move toward the other end. Utilizing the principle of the wedge structure, a strong clamping force can be generated to firmly fix the wire in the wire clamping hole. This design can effectively prevent the wire from slipping or falling off under the influence of various environmental factors, greatly improving the safety and stability of power transmission;

[0012] 2. The product's integral structure is connected by aluminum parts and rigid structures, which avoids problems caused by product deformation due to external factors and improves the product's strength, safety and other performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-Figure 3 As shown, the NXJG wedge-shaped tension clamp provided by the present invention includes a wedge-shaped clamp body 1 and two groups of wedge blocks 2 that are buckled into each other. Bosses 7 are evenly arranged on the outer wall of the wedge-shaped clamp body 1, and anti-slip grooves are provided on the opposite side walls of the two groups of wedge blocks 2, which further enhance the clamping force on the conductor, ensure that the conductor can be firmly clamped under various working conditions, and improve the overall performance of the tension clamp. The wedge-shaped clamp body 1 is covered on the outside of the two groups of wedge blocks 2, and the wedge blocks 2 and the wedge clamp body 1 are arranged to slide relative to each other. A wire clamping hole 3 is formed between the wedge blocks 2. The cross-section of the wedge clamp body 1 is U-shaped, and the open end of the wedge clamp body 1 is slidably connected to a wedge block 4. The wedge block 4 is provided on the two groups of wedge blocks 2, and the wedge block 4 is arranged in an isosceles trapezoidal structure. After the conductor is installed, the wedge block 2 and the wedge block 4 are moved toward the other end by knocking with a wooden hammer, thereby clamping the conductor to prevent slipping or falling off.

[0020] like Figure 1-Figure 3 As shown, the two outer side walls of the wedge-shaped wire clamp body 1 are hinged with pull plates 5, and the two groups of pull plates 5 are symmetrically located on both sides of the wedge-shaped wire clamp body 1. Fastening bolts 6 are passed through the ends of the two groups of pull plates 5 away from the wedge-shaped wire clamp body 1, making the installation and disassembly of the tension wire clamp and the connecting components such as the pole tower simple and quick. The construction personnel can quickly complete the installation work, reducing the construction difficulty, and also facilitating the subsequent maintenance and inspection work, effectively saving manpower and time costs.

[0021] When in use, separate the two sets of wedge blocks 2 at a certain angle, put the wire into the wire clamping hole 3 formed between the wedge blocks 2, adjust the position of the wire so that it is located in the center of the wire clamping hole 3, buckle the two sets of wedge blocks 2 so that the wire clamping hole 3 initially clamps the wire, place the wedge block 4 on the two sets of wedge blocks 2, and align it with the open end of the wedge-shaped wire clamp body 1, use a wooden hammer to gently tap the wedge block 2 and the wedge block 4 to move them to the other end of the wedge-shaped wire clamp body 1. As the tapping continues, the wedge block 2 and the wedge block 4 gradually clamp the wire.

[0022] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
