Technical Field

[0001] The utility model relates to the technical field of parallel groove wire clamps, in particular to a parallel groove wire clamp with adjustable installation angle. Background Art

[0002] The parallel groove clamp is mainly used for connecting aluminum stranded wire or steel core aluminum stranded wire with small and medium cross-section and steel stranded wire of overhead lightning arrester at positions that do not bear tension, such as T-connection, branch line, switch, transformer and other electrical equipment down conductor, lightning arrester grounding down conductor, etc. It can also be used for jumper connection of non-linear towers;

[0003] The parallel groove wire clamp currently used has a short clamping length for the wire and the wire will swing due to wind load, and the installation between the wire and the wire clamp is a fixed structure. Long-term swinging increases the creep of the wire, thereby affecting the connection between the wire clamp and the wire. Therefore, the utility model proposes a parallel groove wire clamp with an adjustable installation angle to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the utility model proposes a parallel groove wire clamp with adjustable installation angle. The parallel groove wire clamp with adjustable installation angle is provided with a rotatable upper wire clamping seat and a lower wire clamping seat. When the wire is shaken by wind, the elastic potential energy of the spring is used to alleviate the force, thereby reducing the shaking amplitude of the wire and further reducing the creep of the wire.

[0006] A further improvement is that both ends of the arc-shaped slide groove and both sides of the connecting rod are provided with limiting posts for limiting the spring, and the limiting posts are plugged into the spring.

[0007] A further improvement is that the elastic potential energies of the multiple groups of springs are equal, the diameters of the multiple groups of springs are 1-1.5CM, and the springs are arc-shaped.

[0008] A further improvement is that the fixing assembly includes a filling plate, fixing holes and bolts, the filling plate is fixed to the middle end of the inner side of the bottom plate and the cover plate, aligned fixing holes are provided on the central axis of the bottom plate, the cover plate and the filling plate, and bolts are inserted into the fixing holes.

[0009] A further improvement is that the top horizontal plane of the filling plate on the bottom plate is lower than the top horizontal plane of the lower wire pressing seat, and the bottom horizontal plane of the filling plate on the cover plate is higher than the bottom horizontal plane of the upper wire pressing seat.

[0010] A further improvement is that the arc-shaped wire grooves of the upper wire pressing seat and the lower wire pressing seat are both provided with anti-slip grooves, and the anti-slip grooves are made of insulating rubber material.

[0011] A further improvement is that the anti-slip pattern includes horizontal patterns and vertical patterns, and the horizontal patterns are arc-shaped.

[0012] The beneficial effects of the utility model are as follows: the utility model provides a rotatable upper wire clamping seat and a lower wire clamping seat, and when the wire is shaken by the wind, the force is alleviated by the elastic potential energy of the spring, thereby reducing the shaking amplitude of the wire and further reducing the creep of the wire. At the same time, the shaking of the wire will drive the upper wire clamping seat and the lower wire clamping seat to adjust their angles, thereby preventing friction between the wire and the end of the clamping seat, further protecting the wire. By providing anti-slip patterns, the friction between the wire and the upper wire pressing seat and the lower wire pressing seat can be increased, thereby increasing the fixing effect of the device on the wire. At the same time, the use of insulating rubber material can increase the insulation performance of the upper wire pressing seat and the lower wire pressing seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1-5 As shown, the present embodiment proposes a parallel groove wire clamp with adjustable installation angle, comprising a base plate 1, a cover plate 2, an upper wire pressing seat 3 and a lower wire pressing seat 4, a fixing component is provided between the base plate 1 and the cover plate 2, two groups of upper wire pressing seats 3 and lower wire pressing seats 4 are symmetrically provided between the base plate 1 and the cover plate 2, a rotating shaft 5 is provided between the two groups of upper wire pressing seats 3 and the cover plate 2, and between the lower wire pressing seat 4 and the base plate 1, connecting rods 6 are fixed at both ends of the inner side of the upper wire pressing seat 3 and the lower wire pressing seat 4, an arc-shaped slide groove 7 adapted to the connecting rod 6 is provided on the base plate 1 and the cover plate 2, and springs 8 are provided at both ends of the arc-shaped slide groove 7, and the spring 8 is connected to the connecting rod 6.

[0021] This device is provided with a rotatable upper wire clamp seat and a lower wire clamp seat. When the wire is shaken by wind, the elastic potential energy of the spring 8 can alleviate the force, reduce the shaking amplitude of the wire, and further reduce the creep of the wire. At the same time, the shaking of the wire will drive the upper wire clamp seat and the lower wire clamp seat to adjust their angles, thereby preventing friction between the wire and the end of the clamp seat, and further protecting the wire.

[0022] Limiting posts 9 for limiting the spring 8 are provided at both ends of the arc-shaped slide groove 7 and at both sides of the connecting rod 6 , and the limiting posts 9 are plugged into the spring 8 .

[0023] The setting of the limit column 9 ensures the connection between the spring 8 and the arc-shaped slide groove 7 and the connecting rod 6, thereby ensuring the use of the elastic potential energy of the spring 8. The elastic potential energy of the spring 8 ensures the stability of the upper wire pressing seat 3 and the lower wire pressing seat 4 when not disturbed by external forces. When subjected to external forces, the force received can be buffered, thereby reducing the shaking amplitude of the wire.

[0024] The elastic potential energies of the multiple groups of springs 8 are equal, the diameters of the multiple groups of springs 8 are 1-1.5CM, and the springs 8 are arc-shaped.

[0025] The fixing assembly includes a filling plate 10, a fixing hole 11 and a bolt 12. The filling plate 10 is fixed to the middle end of the inner side of the base plate 1 and the cover plate 2. Aligned fixing holes 11 are provided on the central axis of the base plate 1, the cover plate 2 and the filling plate 10, and bolts 12 are inserted into the fixing holes 11.

[0026] The device fixes the cover plate 2 and the bottom plate 1 together by means of bolts 12 cooperating with the fixing holes 11, thereby fixing the upper wire pressing seat 3 and the lower wire pressing seat 4 together.

[0027] The top horizontal plane of the filling plate 10 on the bottom plate 1 is lower than the top horizontal plane of the lower wire pressing seat 4 , and the bottom horizontal plane of the filling plate 10 on the cover plate 2 is higher than the bottom horizontal plane of the upper wire pressing seat 3 .

[0028] This structural design can ensure the clamping connection between the lower wire pressing seat 4 and the upper wire pressing seat 3. At the same time, the upper wire pressing seat 3 and the lower wire pressing seat 4 can be fixed with wires of different diameters by the fixing of the bolts 12 and the fixing holes 11.

[0029] The arc-shaped wire grooves of the upper wire pressing seat 3 and the lower wire pressing seat 4 are both provided with anti-skid patterns 13, and the anti-skid patterns 13 are made of insulating rubber.

[0030] By providing the anti-slip grooves 13, the friction between the wire and the upper wire pressing seat 3 and the lower wire pressing seat 4 can be increased, thereby increasing the fixing effect of the device on the wire. At the same time, the use of insulating rubber material can increase the insulation performance of the upper wire pressing seat 3 and the lower wire pressing seat 4.

[0031] The anti-slip pattern 13 includes a transverse pattern 14 and a vertical pattern 15, and the transverse pattern 14 is arc-shaped.

[0032] The parallel groove wire clamp with adjustable installation angle is fixed together with the cover plate 2 and the base plate 1 by the bolts 12 and the fixing holes 11, thereby fixing the upper wire pressing seat 3 and the lower wire pressing seat 4 together, and then fixing the wire. When the wire is shaken by the wind, the elastic potential energy of the spring 8 alleviates the force and reduces the shaking amplitude of the wire. At the same time, the shaking of the wire will drive the upper wire clamping seat and the lower wire clamping seat to adjust their angles, thereby preventing friction between the wire and the end of the clamping seat.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
