[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. It can also be understood as power transmission and transformation industry expansion engineering.

[0003] Cables are often used in power projects. During construction, the cables need to be laid, clamped and positioned. Therefore, wire clamps for power projects are needed.

[0004] Generally, there are multiple cables that need to be clamped side by side, so it is necessary to use side-by-side wire clamps for power engineering cables.

[0005] At present, most of the existing side-by-side wire clamps for power engineering cables cannot conveniently increase or decrease the number of wire clamp bodies according to the number of cables in parallel, which greatly reduces the applicability and convenience of side-by-side wire clamps for power engineering cables. In addition, the existing side-by-side wire clamps for power engineering cables have low clamping stability and anti-slip properties for the outer wall of the cable.

[0006] The above problems are widespread and in urgent need of improvement. Utility Model Content

[0007] The purpose of the present utility model is to provide a new type of wire clamp for power engineering, so as to solve the problems in the existing technology that most of the wire clamp bodies cannot be conveniently increased or decreased according to the number of cables arranged side by side, thereby reducing the applicability and convenience of the side-by-side wire clamp for power engineering cables and the low stability and anti-slip performance of the side-by-side wire clamp for power engineering cables on the outer wall of the cable.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1 、 Figure 2 、 Figure 3 The new type of wire clamp for power engineering shown in the figure includes a wire clamp body 1, which is composed of a bottom clamp block 2 and a top clamp block 3. A nut 21 is welded to the lower end of the bottom clamp block 2, and a bolt 31 is inserted into the top clamp block 3, which is threadedly connected to the nut 21.

[0025] A middle plate 4 is provided between the bottom clamping block 2 and the top clamping block 3. A first connecting block 5 and a second connecting block 6 are provided at both ends of the middle plate 4. A snap-fit ​​groove 51 is provided on the first connecting block 5, and a sliding cavity 61 is provided on the second connecting block 6. A snap-fit ​​block 62 is slidably engaged in the sliding cavity 61. The number of the wire clamp bodies 1 can be conveniently increased or decreased according to the number of cables arranged side by side.

[0026] There are two symmetrical clamping blocks 62, and a spring 63 is provided between the two clamping blocks 62. When the upper and lower limit blocks 64 are pressed at the same time, the upper and lower clamping blocks 62 are driven to exit the clamping groove 51 at the same time. At this time, the spring 63 is compressed and deformed. When the limit block 64 is loosened, the spring 63 rebounds, driving the upper and lower clamping blocks 62 to quickly clamp into the corresponding clamping groove 51, thereby realizing rapid clamping and installation between the two wire clamp bodies 1.

[0027] The cross section of the clamping block 62 is a bent L-shaped structure. The end surface of the clamping block 62 exposed from the sliding cavity 61 is provided with a limiting block 64. The limiting block 64 prevents the clamping block 62 from entering the sliding cavity 61 as a whole when pressed, thereby achieving a limiting effect.

[0028] Both the bottom clamping block 2 and the top clamping block 3 are provided with a cable trough 7, the inner groove wall of the cable trough 7 is provided with a hard pad 8, and the hard pad 8 is provided with an anti-slip top block 81. The anti-slip top block 81 is a conical trapezoidal structure. The anti-slip top block 81 is made of damping silicone material as a whole and has excellent damping friction elasticity.

[0029] The front and rear end surfaces of the hard pad 8 when viewed from above extend beyond the front and rear end surfaces of the cable trough 7 when viewed from above. The hard pad 8 is made of hard vulcanized rubber and has a smooth surface, which prevents the outer wall of the cable from contacting the metal wire clamp body 1 and causing abrasion.

[0030] The anti-skid top blocks 81 are arranged in five groups in a circle, with each group consisting of seventeen blocks arranged in a longitudinal direction, thereby improving the stability and anti-skid properties of the side-by-side wire clamp for power engineering cables on the outer wall of the cable.

[0031] When used in this embodiment: Figure 1 As shown, it is a state diagram of the two wire clamp bodies 1 having been installed. If the wire clamp body 1 on the left needs to be removed, two fingers of both hands can simultaneously press the upper and lower limit buttons 64 to drive the two clamping blocks 62 to move toward each other along the sliding cavity 61. When the right bending parts of the two clamping blocks 62 exit the clamping groove 51, the wire clamp body 1 on the right can be moved to the right. After the clamping block 62 completely exits the clamping groove 51, the two wire clamp bodies 1 can be easily removed. Similarly, if the number of cables to be arranged side by side needs to be increased, a wire clamp body 1 can be conveniently installed.

[0032] The above operation can conveniently increase or decrease the number of the wire clamp bodies 1 according to the number of cables arranged side by side, thereby improving the applicability and convenience of the side-by-side wire clamp for power engineering cables.

[0033] In addition, the cable is placed in the cable groove 7 of the bottom clamping block 2, and then the cable groove 7 on the top clamping block 3 is matched and covered, and then the bolt 31 is passed through and locked with the nut 31. At this time, due to the thread locking force of the bolt 31, the hard pad 8 is squeezed, and the anti-slip top block 81 with high elastic damping friction is fully squeezed into contact with the outer wall of the cable, thereby improving the stable and anti-slip properties of the side-by-side wire clamp for power engineering cables on the outer wall of the cable.
