It is also called fastening hardware or anchoring hardware. It is mainly used to fix the conductor or lightning conductor on the tension insulator string of non-linear pole tower to play an anchoring role. It is also used to fix the guy wire of the guy tower.

[0003] In the prior art, the current tension clamps are usually of bolt type, which use a group of bolts to clamp the wire clamp to fix the conductor. The advantage of the bolt type is that it is easy to install, only a wrench is needed, and no equipment such as hydraulic pliers is required. The disadvantage is that the clamping cotton knots are small, and the clamping is carried out by contacting the guide with the end of the bolt, which is easy to loosen, and there is a potential risk of loosening. In addition, an opening is usually provided on the wire clamp, and the guide is easy to fall out of the opening of the wire clamp body when clamping. Therefore, a convenient wedge tension clamp is designed to solve the above problems. Utility Model Content

[0027] Example:

[0028] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a portable wedge tension wire clamp, comprising a wire clamp body 1 and a wedge 2, a wedge-shaped groove 101 is provided in the center of the upper surface of the wire clamp body 1, track grooves 102 are provided above the left and right side surfaces of the wedge-shaped groove 101, and tooth grooves 103 are provided below the track groove 102, track rods 201 are provided above the left and right side surfaces of the wedge 2, an installation groove 202 is provided above the outer side surface of the wedge 2, a positioning assembly is installed in the installation groove 202, and a locking assembly is installed on the left side of the wedge 2.

[0029] In this embodiment, the track rod 201 is in an inverted "convex" shape, and the track rod 201 slides in the track groove 102, ensuring the stability of the track rod 201 in the track groove 102 and facilitating the removal of the wedge 2 from the wire clamp body 1.

[0030] In this embodiment, the positioning assembly includes a guide rod 3, a tooth plate 301 and a sleeve spring 302. Tooth plates 301 are provided at both ends of the guide rod 3. A sleeve spring 302 is fixedly provided between the two tooth plates 301. The locking assembly includes a locking bolt 4 and an extrusion plate 401. The locking bolt 4 is threadedly connected to the right side surface of the wedge 2. The end of the locking bolt 4 is rotatably provided with an extrusion plate 401 through a bearing.

[0031] In this embodiment, the thickness of the tooth plate 301 is equal to the thickness of the mounting groove 202 , and a through hole matching the guide rod 3 is provided on the side of the tooth plate 301 to facilitate the left and right movement of the tooth plate 301 along the guide rod 3 .

[0032] In this embodiment, the length of the guide rod 3 is not greater than the width of the mounting groove 202, and when the sleeve spring 302 is in a naturally extended state, the distance between the outer sides of the two tooth plates 301 is not greater than the width of the mounting groove 202, ensuring that the tooth plates 301 are completely in the mounting groove 202.

[0033] In this embodiment, the latching teeth on the tooth plate 301 match the latching tooth groove 103, and the vertical distance between the tooth plate 301 and the track rod 201 is equal to the vertical distance between the track groove 102 and the latching tooth groove 103. When the track rod 201 is embedded in the track groove 102, the tooth plate 301 and the latching tooth groove 103 are at the same horizontal height, and it is convenient for the tooth plate 301 to be latched in the latching tooth groove 103.

[0034] In this embodiment, the thickness of the extrusion plate 401 is equal to the height of the mounting groove 202 , and the extrusion plate 401 is located in the mounting groove 202 , thereby ensuring the stability of the movement of the extrusion plate 401 in the mounting groove 202 .

[0035] In this embodiment, the squeezing plate 401 is in the shape of an isosceles trapezoid with a smaller width toward the positioning assembly and a wider width away from the positioning assembly, so that the squeezing plate 401 can push the two tooth plates 301 apart so that the tooth plates 301 are engaged in the tooth grooves 103 .

[0036] In this embodiment, when the outer side of the extrusion plate 401 is attached to the outer end of the installation groove 202 , the inner end of the extrusion plate 401 extends between the two tooth plates 301 , and the extrusion plate 401 can prevent the positioning assembly from falling out from between the tooth plates 301 .

[0037] Working principle: when the cable needs to be clamped, place the cable to be clamped in the wedge-shaped groove 101, then embed the track rod 201 on the wedge 2 into the track groove 102, move to the left and knock the wedge 2, so that the distance between the bottom of the wedge 2 and the bottom of the wedge groove 101 gradually becomes smaller, so that the bottom of the wedge 2 cooperates with the wedge groove to clamp the cable, and then turn the locking bolt 4 on the locking assembly. The locking bolt 4 drives the extrusion plate 401 to move along the installation groove 202 to one side of the positioning assembly, and the extrusion plate 401 pushes the two tooth plates 301 apart, so that the teeth on the tooth plates 301 are engaged in the tooth groove 103, so as to achieve the effect of positioning the wedge 2. The operation is simple and convenient.

[0038] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
