DETAILED DESCRIPTION

[0057] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0058] Embodiment 1

[0059] See also Figure 1-11 The present invention provides a technical solution: a variable spacer capable of live operation, comprising: an insulating ring 1, on which a plurality of connecting grooves 2 are arranged in a circular array;

[0060] A plurality of insulating rods 3 are arranged at the connection slot 2. The end of the insulating rod 3 at the connection slot 2 is provided with a connection unit 4 used in conjunction with the connection slot 2, which is used for plugging and fixing the insulating rod 3 and the insulating ring 1 to achieve rapid fixation of the insulating rod 3 and the insulating ring 1. The end of the insulating ring 1 away from the connection unit 4 is provided with a clamping unit 5 for clamping the wire;

[0061] A plurality of auxiliary support rods 6 are arranged between two adjacent insulating rods 3, and are used to cooperate with the two insulating rods 3 connected thereto and the insulating ring 1 to form a stable triangular support structure. Matching mounting holes are provided at the connection between the insulating rod 3 and the auxiliary support rod 6, and are used to connect the auxiliary support rod 6 and the insulating rod 3 by means of a latch or the like.

[0062] Wherein, the connecting groove 2 is convexly arranged, and the connecting unit 4 comprises:

[0063] Two groups of clamping blocks 41 symmetrically arranged at the ends of the insulating rods 3 and clamped with the connecting grooves 2, the clamping blocks 41 are slidably arranged on the insulating rods 3, and a compression spring 42 is arranged between the clamping blocks 41 and the insulating rods 3, wherein the outer end surface of the clamping blocks 41 is arranged in a right-angle trapezoidal shape, so that the clamping blocks 41 can be inserted into the connecting grooves 2;

[0064] The button 43 is limited and slidable and symmetrically arranged on the insulating ring 1 on both sides of the convex inner end of the connecting groove 2. The first limited sliding groove 44 is arranged at the sliding connection between the button 43 and the insulating ring 1, and the first limited sliding groove 44 is connected to the connecting groove 2;

[0065] When the insulating rod 3 is plugged in and removed from the insulating ring 1, the block 41 can be aligned with the inlet of the connecting groove 2 and inserted. The right-angled trapezoidal setting of the block 41 will automatically be inserted into the connecting groove 2. At the same time, due to the inclined surface setting of the right-angled trapezoid, there is no need to manually pinch the block 41 into the insulating rod 3, so that the operator can operate it conveniently. At this time, the compression spring 42 will be compressed. After the block 41 is inserted into the connecting groove 2, the compressed compression spring 42 will pop out the block 41, thereby realizing the connection between the insulating rod 3 and the insulating ring 1;

[0066] When disassembling, it is only necessary to press the buttons 43 into the first limiting sliding grooves 44 from both sides of the insulating ring 1 to squeeze the block 41 into the insulating rod 3 , and then the insulating rod 3 can be pulled out of the insulating ring 1 .

[0067] At the same time, the clamping unit 5 includes:

[0068] A semi-conducting slip ring 51 is fixedly provided with the end of the insulating rod 3, and two end portions of the semi-conducting slip ring 51 are provided with limiting plates 52;

[0069] Two clamping half rings 53 are limitedly sliding in an arc shape on both sides of the semi-guide slip ring 51. A second limiting sliding groove 54 for limiting sliding with the semi-guide slip ring 51 is arranged inside the clamping half ring 53. A return spring 55 is sleeved on the outer wall of the semi-guide slip ring 51 located in the second limiting sliding groove 54. The return spring 55 is arranged between the limiting piece 52 and the inner end of the second limiting sliding groove 54.

[0070] The sliding adjustment component 56 is disposed between the two clamping half rings 53 and the insulating rod 3 and is used to adjust the opening and closing of the control component;

[0071] In addition, when installing the spacer rod as a whole and the power transmission line according to the actual situation, first make the two clamping half rings 53 on the clamping unit 5 in the open state, and then put the power transmission line into the clamping groove formed by the clamping half rings 53 in turn, so that the spacer plate as a whole will stretch the power transmission line, and the spacer rod will also initially fix the spacer plate through the power transmission line and the reverse force of the stretching, and then the clamping half ring 53 will be synchronously closed through the sliding adjustment component 56 to realize the closure of the clamping half ring 53 on each insulating rod 3 to achieve the clamping of the power transmission.

[0072] Wherein, the sliding adjustment component 56 includes:

[0073] The third limiting sliding groove 561 is provided inside the end of the insulating rod 3 close to the semi-conductive slip ring 51, and the third limiting sliding groove 561 is hollowed out, and a limiting sliding block 562 is slidably arranged in the third limiting sliding groove 561;

[0074] Two sets of rotating plates 563 are symmetrically arranged with the insulating rod 3 as the symmetry axis, one end of which is rotatably arranged at the hollow part of the third limiting sliding groove 561 and the limiting sliding block 562, and the other end is rotatably arranged with the clamping half ring 53 close to one end of the insulating rod 3;

[0075] The threaded rod 564 is threadedly connected to the limiting slider 562, one end of which is rotatably arranged at the upper end of the third limiting slide groove 561, and the other end of which penetrates the insulating rod 3 and extends to the outside of the insulating rod 3;

[0076] The limit adjustment member 565 is arranged between the limit slider 562 and the hollow position of the outer wall of the insulating rod 3, and is used to limit the downward position of the limit slider 562 in one direction to prevent the threaded rod 564 from rotating to cause the limit slider 562 to slide down, causing the opening of the two clamping half rings 53 to become larger, so that the wire is disengaged from the clamp, and at the same time makes the clamping more stable.

[0077] In addition, the limit adjustment member 565 includes:

[0078] Two groups of abutting semicircular grooves 566 symmetrically arranged at the hollowed-out portion of the third limiting sliding groove 561, wherein one group of the abutting semicircular grooves 566 is composed of a plurality of semicircular groove arrays with their opening directions inclined upward;

[0079] Two groups of abutment posts 567 used in conjunction with the abutment semicircular grooves 566, wherein a rotating bar is fixedly disposed at the inner end of the abutment posts 567, and a rotating disc 568 is disposed at one end of the rotating bar away from the abutment posts 567, and the rotating disc 568 is rotatably disposed on the limiting slider 562;

[0080] The adjusting portion 569 is arranged between the rotating disk 568, the limiting slider 562 and the abutting semicircular groove 566, and is used for limiting the rotation angle of the rotating disk 568 and applying an outward force in real time when the abutting column 567 moves upward with the limiting slider 562, so that the abutting column 567 can be stuck in the semicircular groove when passing through each semicircular groove. At the same time, when the abutting column 567 moves to the uppermost semicircular groove and continues to move upward, the abutting column 567 is limited to move out of the semicircular groove and maintain a vertical downward state. At this time, when the limiting slider 562 moves downward, it will not be affected by the unidirectional limitation of the abutting semicircular groove 566 until it moves to the lowermost end of the abutting semicircular groove 566, releasing the vertical state and resetting it.

[0081] Wherein, the adjustment unit 569 includes:

[0082] The elastic sheet 5691 is rotatably disposed on the limit slider 562, and a torsion spring is disposed at the rotation connection with the limit slider 562, so that the elastic sheet 5691 has a force to rotate in the direction of abutting the semicircular groove 566;

[0083] The arc-shaped notch 5692 is formed on the rotating disk 568, and the end of the elastic sheet 5691 abuts against the arc-shaped notch 5692 to limit the rotation of the rotating disk 568, so that when the abutting column 567 moves upward, it abuts against each semicircular groove it passes through;

[0084] The inwardly inclined limiting surface 5693 is arranged at the uppermost end of the abutting semicircular groove 566, and is used for when the abutting column 567 slides to this position, due to the arrangement of the inwardly inclined limiting surface 5693, the abutting column 567 can rotate to a vertical state when it continues to move upward;

[0085] The limiting notch 5694 is provided in the inward rotating direction of the rotating disc 568 and is located at the lower end of the arc-shaped notch 5692. When the rotating column is limited to the vertical state by the inwardly inclined limiting surface 5693, the rotating disc 568 rotates, and the end of the elastic sheet 5691 slides from the arc-shaped notch 5692 to the limiting notch 5694 and is stuck therein, and is kept stuck therein under the action of the torsion spring, so that when the limiting slider 562 slides downward, it will not be unidirectionally limited by the abutting column 567.

[0086] The outwardly inclined limiting surface 5695 is arranged at the lowermost end of the abutting semicircular groove 566. After the limiting slider 562 slides to the lowermost end to open the two clamping half rings 53, the abutting column 567 will move due to the limiting effect of the outwardly inclined limiting surface 5695, so that the rotating disk 568 rotates, and the elastic sheet 5691 slides out of the limiting notch 5694 and enters the arc-shaped notch 5692. At this time, the abutting column 567 is subjected to the outward force again. When it moves up again, the movement of the limiting slider 562 is limited in one direction. Through the one-way limitation, when the threaded rod 564 accidentally rotates a small amount, its rotation direction is limited to prevent its rotation from causing the clamping half ring 53 to open and the wire to fall off.

[0087] Among them, a limiting plate 8 is provided at the upper end of the insulating rod 3 at the inwardly inclined limiting surface 5693 to limit the upward movement of the abutment column 567 and prevent it from sliding into the inwardly inclined limiting surface 5693 to release its one-way limiting effect, and the limiting plate 8 is detachably installed on the insulating rod 3. When the spacer rod is disassembled and the clamping half ring 53 needs to be opened, the limiting plate 8 can be removed first.

[0088] In addition, the elastic sheet 5691 is arranged in an L shape, so that the elastic sheet 5691 can better abut against the arc-shaped notch 5692 and be inserted into the limiting notch 5694.

[0089] At the same time, a first bevel gear 5641 is provided at one end of the threaded rod 564 away from the clamping half ring 53, and a plurality of through holes connected to the connecting groove 2 are provided on the insulating ring 1, so that the first bevel gear 5641 can pass through the through holes and enter the inner ring of the insulating ring 1 after the insulating rod 3 is plugged into the insulating ring 1;

[0090] The power unit 7 is disposed on the insulating ring 1 and is used to synchronously drive the first bevel gears 5641 at the ends of the plurality of threaded rods 564 inserted into the insulating rods 3 to rotate.

[0091] Finally, the power unit 7 comprises:

[0092] The second bevel gear 71 is rotatably arranged at the axis center of the insulating ring 1 and meshed with the plurality of inserted first bevel gears 5641. A rotating shaft 72 is fixedly arranged at the axis center of the second bevel gear 71. A shaft plate is arranged on one side of the insulating ring 1 for rotating the rotating shaft 72. Circular plates are arranged on both sides of the shaft plate for realizing fixed-point rotation of the rotating shaft 72. A rotating disk 73 is fixedly arranged at one end of the rotating shaft 72 away from the second bevel gear 71 for manually rotating and driving the rotating shaft 72 to rotate.

[0093] By disposing the second bevel gear 71 in the power unit 7 , a plurality of inserted first bevel gears 5641 can be driven to rotate at the same time, so as to realize the rotation of the threaded rod 564 , thereby driving the limit slider 562 to move up and down.

[0094] Embodiment 2

[0095] See also Figure 1 and Fig.12 as well as Fig.13 The difference between this embodiment and the first embodiment is that the insulating rods 3 are arranged in three groups, and the angles between them are 60 degrees and 120 degrees respectively, which is used when the number of transmission line groups is 3 and the connection diagram when the spacer device is installed after the transmission line is erected. When the connection diagram does not only mean that the connection angles of the insulating rods 3 are only 60 degrees and 120 degrees.

[0096] Also, see Fig.14 An insulating connecting rod 9 is provided between adjacent insulating rods 3, and the insulating connecting rod 9 and the insulating rod 3 are connected by an auxiliary support rod 6, which is used to set the insulating connecting rod 9 to reduce the angle of the triangular support structure when the angle between two adjacent insulating rods 3 is large, so as to make the triangular support structure more stable, and at the same time, the insulating connecting rod 9 is plugged into the insulating ring 1 through the connecting unit 4;

[0097] When the insulating connecting rod 9 is arranged at a large angle between two adjacent insulating rods 3, Fig.13 It is a schematic diagram of overall connection of two adjacent insulating rods 3 with an angle of 120 degrees.

[0098] Embodiment 3

[0099] See also Fig.15 , the difference between this embodiment and the first and second embodiments is that when the number of insulating rods 3 is 4 groups, the corresponding number of transmission lines is 4 groups, which is a schematic diagram of the overall installation structure of the spacer rods.

[0100] Finally, it should be noted that in order to adapt the device to the installation of insulating rods 3 in different situations, the connecting grooves 2 on the insulating ring 1 are generally set to 12 groups, and the length model of the insulating rods 3 is matched according to actual conditions, so that the adaptability of this type of spacer device is stronger.

[0101] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
