The wire clamp hull 11 and the wire pressing plate 12 can be positioned in a pin shaft mode, namely positioning pins 13 can be respectively arranged at the two ends of the wire pressing plate 12, and the positioning pins 13 are clamped at the two end surfaces of the wire clamp hull 11 during installation, so that the wire pressing plate 12 can be prevented from slipping from the two ends of the wire clamp hull 11; the clamping grooves 14 can be further arranged at the two ends of the online clamping ship body 11, and the positioning pins 13 are clamped in the clamping grooves 14.
The pressing part 2 can be pressed above the wire pressing plate 12 of the wire clamping part 1, so that the wire pressing plate 12 can be pressed down, and the wire pressing plate 12 and the wire clamp hull 11 can jointly act to press and fix the wire 5. The pressing part 2 may include a housing 21 and a pressing bolt 22 penetrating through the housing 21, and when the pressing bolt 22 is rotated downwards, the pressing and fixing of the wire 5 may be completed by pressing the pressing plate 12, so that the installation of the wire is very convenient. The pressing portions 2 may be provided one at each end of the longitudinal axis of the wire holding portion 1.
The adjusting part 3 is hinged on the wire clamp hull 11 of the wire clamping part 1, and the adjusting part 3 is also connected on the pressing part 2. Specifically, the adjusting portion 3 is rotatably movably connected to the housing 21 of the pressing portion 2. The adjusting part 3 may include two connection plates 31, the two connection plates 31 are respectively located at the front and rear sides of the wire clamping part 1 and the compressing part 2, and the two connection plates 31 may be L-shaped, the middle part of the L-shaped connection plate 31 is hinged on the wire clamping hull 11, and the compressing part 2 is connected at one end of the L-shaped connection plate 31. Similarly, two pressing portions 2 are provided opposite to each other, and two adjusting portions 3 are provided.
The hanging part 4 is provided with a pin 41, and the adjusting part 3 is movably connected with the hanging part 4 through the pin 41. Specifically, the hanging portion 4 may be movably connected to the other end of the L-shaped connecting plate 31 through a pin 41, and the other end of the L-shaped connecting plate 31 may be provided with a long hole or a long groove 32 for movably connecting with the pin 41, so that the pin 41 has a lateral movement space. The hanging part 4 is also provided with a resisting part positioned below the wire clamping part 1. In this embodiment, the hanging part 4 includes a hanging plate 42 and a base 43, where the hanging plate 42 may be disposed on the front and rear sides of the wire clamping part 1, and an arc chute 44 is disposed on the hanging plate to cooperate with a shaft 45 on the base 43; the base 43 is provided with the pin shaft 41, and the hanging plate 42 is hinged on the pin shaft 41; the base 43 has a U-shaped structure with a U-shaped bottom surface supported below the clamp hull 11 of the wire clamping part 1, and an edge of the U-shaped bottom surface forms the abutment 46.
Further, the present invention may further provide an anti-reverse structure capable of preventing the reverse rotation of the adjustment portion 3. In this embodiment, the bottom surface of the U-shaped base 43 of the suspension part 4 restricts the upward space of the suspension part 4, so that the adjustment part 3 can be prevented from rotating reversely. A boss 15 may be further disposed on the top surface of the wire pressing plate 12 of the wire clamping portion 1 corresponding to the inner side of the pressing portion 2, so as to prevent the pressing portion 2 from rotating reversely, and further limit the adjusting portion 3 from rotating reversely.

The suspension clamp can rotate within a set small range of angles, as shown in fig. 4, when the tension of a wire at one end of the clamp is larger than that at the other end, the wire clamping part 1 rotates around the pin shaft 41 of the suspension part 4, when the tension is smaller than the set range, the suspension part 4 only moves within a small range, the unbalanced tension disappears, and the whole device can automatically reset under the action of gravity. The mode can lead the suspension clamp to carry out unbalanced tension adjustment in a small range without loosening the lead.
When the unbalanced tension at one end is greater than the set value, the rotation angle of the hanging part 4 is increased and is greater than the set rotation angle (shown in fig. 5 and 6), the resisting part below the hanging part is limited to continuously rotate around the pin shaft 41, so that the hanging part 4 is changed to rotate around the resisting part 46, the pin shaft 41 drives the other end of the adjusting part 3 to rotate downwards, the adjusting part 3 drives the compressing part 2 to rotate inwards, the bottom of the compressing part 2 is further loosened to the compressing state of the wire pressing plate 12, and the conducting wire 5 is released to enable the conducting wire to move back and forth in the wire clamping part 1; when the unbalanced tension disappears, the whole suspension clamp is reset under the action of gravity or under the combined action of the reset spring 6, and the lead 5 is compressed again to reach a new balanced state; if one end of the wire is broken, the wire can be directly pulled away from the wire clamping part 1, so that the high-voltage wire tower can be prevented from being pulled down by excessive pulling force, and the tower falling accident is avoided.
With the above embodiment, when adjusting in a small angle range, only the hanging plate 42 of the hanging part 4 rotates around the pin 41, and the base 43 is not moved; when the unbalanced tension at one end is greater than the set value, the edge of the arc chute 44 on the hanging plate 42 of the hanging part 4 is propped against the shaft 45 of the base 43, so that the shaft 45 drives the base 43 to rotate together with the hanging plate 42, the U-shaped bottom edge of the base 43 (namely the resisting part 46) becomes a new rotation shaft, the hanging plate 42 and the base 43 rotate together around the resisting part 46, and the pin shaft 41 drives the other end of the adjusting part 3 to rotate downwards; the following operation is the same as in the previous section and will not be described in detail.
As shown in fig. 7, in order to illustrate a second embodiment of the present invention, the suspension clamp according to the present embodiment also includes a wire clamping portion 1, a pressing portion 2, an adjusting portion 3, and a hanging portion 4', wherein the general structures of the wire clamping portion 1, the pressing portion 2, and the adjusting portion 3 according to the present embodiment are the same as those of the first embodiment, and reference numerals are also the same in the drawings, and will not be described in detail.
The difference of this embodiment is that the hanging portion 4 'includes a hanging plate 42', and the hanging plate 42 'may be disposed on each of the front and rear sides of the wire clamping portion 1, and the pin 41' is disposed thereon and is movably connected to the adjusting portion 3. A retaining shaft 46' is arranged below the hanging plate 42' to form the retaining part, and the retaining shaft 46' has a gap relative to the bottom of the wire clamping body 11 of the wire clamping part 1.
In addition, in this embodiment, a support shaft 33 is disposed below the L-shaped connection plate 31, and the support shaft 33 is located below the wire clamping portion 1, and functions to support the wire clamping portion 1 on the one hand, and can serve as an anti-reverse structure for preventing the adjustment portion 3 from rotating reversely.
In this embodiment, when the adjustment is performed within a small angle range, the hanging portion 4' is also rotated around the pin 41', and in this state, the resisting shaft 46' is not in contact with the bottom of the clamp hull 11. When the tension at one end is larger than the set value, the rotation angle of the hanging part 4 'is increased to enable the resisting part 46' to be in contact with the bottom of the wire clamp hull 11, the hanging part 4 'rotates around the resisting shaft 46', so that the adjusting part 3 is driven to rotate, the pressing part 2 is driven to rotate, and the purpose of releasing the wires is achieved.
The above description is only of the preferred embodiments of the present invention, and should not be taken as limiting the technical scope of the present invention, but all changes and modifications that come within the scope of the invention as defined by the claims and the specification are to be embraced by the invention.
