[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] Embodiment 1:

[0025] like Figure 1-Figure 8 As shown, the utility model discloses a wire fixer, comprising at least two screws 1 and a clamping member 2 arranged at the lower end of the screw 1, the clamping member 2 is used to connect with a porcelain bottle 21, a pressing plate 3 is arranged at the upper end of the screw 1, a through hole corresponding to the screw 1 is arranged on the pressing plate 3, the screw 1 is locked with a nut 6 after passing through the through hole, a slide groove 12 is arranged on the lower surface of the pressing plate 3, a slider 4 is arranged in the slide groove 12, an arc-shaped groove 11 penetrating the slider 4 is arranged on the lower surface of the slider 4, the wire 22 is located between the groove 11 of the slider 4 and the porcelain bottle 21, the axial direction of the groove 11 is consistent with the sliding direction of the slider 4 on the slide groove 12, and limit blocks 16 are arranged at both ends of the slide groove 12 for limiting the slider 4 from falling off from the slide groove 12.

[0026] Since the porcelain bottle 21 is a columnar structure with a right annular protrusion on the circumference, the clamp 2 is an annular structure and can be clamped between the two annular protrusions on the top, so the connection is firm. At the same time, two screws 1 can be connected to the clamp 2 and extend upward, and the pressure plate 3 is connected to the screw 1 and is limited to the top of the porcelain bottle 21 by the nut 6. The slider 4 is slidably set in the slide groove 12, and the wire 22 is pressed between the porcelain bottle 21 and the slider 4. Under normal circumstances, the slider 4, the wire 22, and the porcelain bottle 21 are relatively fixed because the pressure plate 3 presses the slider 4, the wire 22, and the porcelain bottle 21. When the wire 22 is subjected to external forces such as wind and generates a large pulling force, the slider 4 and the pressure plate 3 can slide, thereby causing a certain displacement between the wire 22 and the porcelain bottle 21, reducing the force on the porcelain bottle 21, and generating a certain buffer, thereby avoiding damage to the porcelain bottle 21, etc., and having higher safety.

[0027] In addition, when the wire 22 is used outdoors for a long time, the sag of the wire 22 will change due to the influence of external factors such as cold and heat and the aging of the wire 22, so that the force exerted by the wire 22 on the porcelain bottle 21 will change, which may easily cause damage to the porcelain bottle 21. However, in the solution of the present application, after the wire 22 is fixed by the slider 4 and the porcelain bottle 21, when the sag of the wire 22 changes, the wire 22 and the slider 4 on the porcelain bottle 21 will move accordingly under the action of the force, so as to maintain the mutual balance of the force on the wire 22 between each porcelain bottle 21, so as to improve safety and reliability.

[0028] The slide groove 12 is a dovetail structure, and the top of the slider 4 is a dovetail structure, and the top of the slider 4 cooperates with the slide groove 12. The dovetail structure between the slide groove 12 and the slider 4 makes the slider 4 slide more stably in the slide groove 12, and at the same time, its lateral bearing capacity is greater and the safety is higher.

[0029] A concave hole 7 is provided in the middle part of the top of the slider 4, a steel ball 9 is provided inside the concave hole 7, a compression spring 8 is provided in the concave hole 7 inside the steel ball 9, the opening diameter of the concave hole 7 is reduced, the steel ball 9 is partially located outside the through hole, and a concave cavity 10 is provided on the bottom wall of the slide groove 12 in the middle part of the length direction, and the steel ball 9 cooperates with the concave cavity 10 for positioning. The slider 4 can be positioned in the middle part of the slide groove 12 of the pressing plate 3 by the compression spring 8 and the steel ball 9. In this way, before installation and use, the slider 4 is always in the middle part, which is convenient for installation and use. After use, after the slider 4 on the pressing plate 3 and the porcelain bottle 21 clamp and press the wire 22, when the wire 22 is subjected to external force and needs to move, the steel ball 9 is subjected to external force to overcome the compression spring 8 and enter the concave hole 7, thereby not affecting the movement of the slider 4 in the slide groove 12.

[0030] A plurality of arc grooves 17 are arranged on the bottom wall of the slide 12, and a plurality of arc protrusions 18 are arranged on the top surface of the slider 4, and the axial directions of the arc grooves 17 and the arc protrusions 18 are perpendicular to the length direction of the slide 12. The matching design of the arc grooves 17 and the arc protrusions 18 can effectively increase the sliding resistance between the slider 4 and the slide 12, so that the two are relatively fixed during normal use, and only when the wire 22 is subjected to a large external force, will it slide and generate buffering, so as to protect the porcelain bottle 21 from damage and improve the safety of the equipment.

[0031] The slider 4 includes a connecting portion 19 and a holding portion 20. The holding portion 20 is made of rubber. The arc groove 17 is arranged on the holding portion 20. A dovetail groove structure is arranged at the lower end of the connecting portion 19. A dovetail structure is arranged at the upper end of the holding portion 20. The dovetail groove structure and the dovetail structure between the connecting portion 19 and the holding portion 20 cooperate with each other and are in a direction perpendicular to the length direction of the slide groove 12. The dovetail structure of the slider 4 involves the connecting portion 19 and the holding portion 20. The holding portion 20 is made of rubber material, which can increase the friction between the holding portion 20 and the conductor 22 and is not easy to cause damage to the conductor 22. In addition, the holding portion 20 and the connecting portion 19 are also matched through the dovetail groove and the dovetail structure. At the same time, the dovetail structure of the connecting portion 19 is a part of the dovetail structure of the slider 4. At the same time, the dovetail groove on the connecting portion 19 is perpendicular to the slide groove 12 on the pressure plate 3. Figure 7 As shown, when the dovetail structure of the entire slider 4 cooperates with the slide groove 12, a part of the dovetail structure of the holding portion 20 is located in the slide groove 12. At this time, both sides of the slide groove 12 can effectively limit the movement of the dovetail structure of the holding portion 20 in the dovetail groove of the connecting portion 19, so no external force is required, and the holding portion 20 and the connecting portion 19 are firmly and stably fixed.

[0032] A plurality of through holes are arranged on the pressure plate 3 corresponding to the bottom wall of the chute 12 on both sides of the inner concave cavity 10, and the through holes are arranged at intervals along the length direction of the chute 12, and different colors are arranged on the top of the slider 4 on both sides of the steel ball 9. Since the device and the porcelain bottle 21 fix the wire 22 and are located at the top of the tower, it is difficult to judge whether the slider 4 is pulled to one side of the chute 12 during maintenance and inspection. If it is moved to one side, it is necessary to correct the position or replace it. Therefore, the present scheme sets a plurality of through holes on the pressure plate 3 on the chute 12. By observing the corresponding position of the color on the slider 4 from the through holes, the position of the slider 4 can be judged, thereby judging whether the slider 4 is pulled to the side by the wire 22. If it is already on the side, it is replaced or adjusted, so it can be observed more conveniently.

[0033] The clamping member 2 includes two arc-shaped bodies 13, and the number of the screw rods 1 is two. A limit block 14 is provided at the lower end of the screw rod 1, a connecting hole 23 is provided at one end of the arc-shaped body 13, and a long hole 15 is provided at the other end of the arc-shaped body 13. The length and width of the limit block 14 are both correspondingly smaller than the length and width of the long hole 15, and the length of the limit block 14 is greater than the width of the long hole 15. Since the outer wall of the porcelain bottle 21 has an annular protrusion, during normal installation, the two arc-shaped bodies 13 can be embraced between the annular protrusions of the porcelain bottle 21 and clamped by the screw rod 1 to achieve its fixation on the porcelain bottle 21. A limit block 14 is provided at the lower end of the screw rod 1, and the length of the limit block 14 is greater than the diameter of the screw rod 1, and the connecting hole 23 at the end of the arc-shaped body 13 is directly sleeved on the screw rod 1, and is limited by the limit block 14 to prevent it from falling off. The arc body 13 can rotate freely on the screw rod 1, so that the arc body 13 can be wrapped around the porcelain bottle 21 during the installation process. The long holes 15 at the other ends of the two arc bodies 13 are stacked after the arc bodies 13 are wrapped around the porcelain bottle 21. At this time, the limiting long block 14 at the lower end of the other screw rod 1 passes through the long hole 15 and rotates a certain angle to keep the length direction of the limiting long block 14 consistent with the width direction of the long hole 15, so that the arc body 13 can be connected and limited. After the locking nut 6 at the top of the screw rod 1 is locked with the screw rod 1, the entire device can be fixed on the porcelain bottle 21, and the wire 22 is fixed between the pressing block 4 and the porcelain bottle 21.

[0034] A mounting seat 24 is provided at the end of the long hole 15 of each arc-shaped body 13, and a screw hole is provided in the mounting seat 24. A tightening bolt 25 is inserted in the screw hole, and the two tightening bolts 25 are arranged in opposite directions. Since the size of the porcelain bottle 21 may be slightly different during actual use, in order to adapt to porcelain bottles 21 of different sizes, the length of the long hole 15 needs to be larger than the diameter of the screw rod 1, that is, the screw rod 1 can have a certain activity space in the long hole 15, and at the same time, after the screw rod 1 and the long hole 15 are matched, the opening and closing degree between the two arc-shaped bodies 13 can be adjusted within a certain range. A mounting seat 24 and a tightening bolt 25 are provided at the end of the long hole 15 of each arc-shaped body 13, and the two tightening bolts 25 are used to relatively press against the screw rod 1, thereby limiting the position of the screw rod 1 in the long hole 15, so as to adjust the opening between the two arc-shaped bodies 13 to adapt to the size of the porcelain bottle 21.

[0035] A protective cover 5 is provided on the pressing plate 3 , and the protective cover 5 covers the pressing plate 3 , the screw rod 1 and the nut 6 .

[0036] This structure can protect the screw 1, the nut 6, etc., and prevent them from being corroded by rain and other external factors, causing rust and being unable to be disassembled.
