DETAILED DESCRIPTION

[0045] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0046] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0047] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0048] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes an insulating operating rod, including: an outer tube 1; a telescopic rod 4, which is slidably arranged in the outer tube 1, and the telescopic rod 4 extends or retracts the outer tube 1 along the axis direction of the outer tube 1; a driving member 8, which is rotatably arranged in the outer tube 1, and the other end is threadedly arranged on the telescopic rod 4. After the driving member 8 rotates, it drives the telescopic rod 4 to move along the axis direction of the outer tube 1. It should be noted that the outer tube 1 is a hollow structure, and the telescopic rod 4 is installed in the outer tube 1. When in use, the telescopic rod 4 can extend out of the outer tube 1, but will not slip off the outer tube 1. When not in use, the telescopic rod 4 can be completely retracted into the outer tube 1, which is not only convenient to carry, but also can protect the telescopic rod 4 and prevent the telescopic rod 4 from bending or even breaking.

[0050] In the above scheme, the outer cylinder 1 usually adopts a cylindrical hollow tube 401, but a square tube can also be adopted, which is not limited here. The telescopic rod 4 selects a retractable length according to actual use. Specifically, in the same working position, different positions of different power distribution equipment or lines may have different heights. After the telescopic rod 4 extends out of the outer cylinder 1 and the length is fixed, the operator controls the driving member 8 to control the telescopic rod 4 to rise and fall in the outer cylinder 1, thereby achieving fine adjustment of the overall extension length of the telescopic rod 4 to adapt to power distribution equipment or lines at different heights, thereby improving the practicality of the device. It should be noted that if the height difference between power distribution equipment or lines at two different positions is too large, it is necessary to replace the telescopic rod 4 that can be used at a higher height.

[0051] Reference Figure 5 Furthermore, the working end cap 6 has a mounting groove 603 , and the end of the telescopic rod 4 away from the outer tube 1 is detachably arranged in the mounting groove 603 .

[0052] In the above scheme, the working end cap 6 is detachably mounted on the top of the telescopic rod 4 through the mounting groove 603, which is convenient for replacing the working end cap 6. It is understandable that the working part 602 can use different tools, such as hook-shaped, clamping and screwing structures, to adapt to the operation requirements of different power equipment such as switching, disassembly, and adjustment. When the telescopic rod 4 is fully retracted into the outer tube 1, the working end cap 6 can be screwed with the outer tube 1, which is convenient for retracting the telescopic rod 4 into the outer tube 1, protecting the telescopic rod 4, and making it easy to carry.

[0053] Reference Figure 6~Figure 7 Furthermore, the inner wall of the mounting groove 603 has an internal threaded portion 605, and the outer wall of the outer tube 1 has an external threaded portion 103. After the telescopic rod 4 is retracted into the outer tube 1, the internal threaded portion 605 is threadedly connected with the external threaded portion 103.

[0054] In the above solution, when the insulating operating rod is not in use, the working end cap 6 and the outer tube 1 can be directly screwed together to realize the folding of the insulating operating rod, which is convenient for carrying and can also prevent the telescopic rod 4 from breaking. Specifically, the external threaded portion 103 is provided on the circumference of the outer wall of the outer tube 1 near the working end cap 6. When in use, it is only necessary to unscrew the mounting seat 601 from the outer tube 1, which is easy to operate.

[0055] Furthermore, the outer tube 1 has a mounting portion 101 ; and further comprises: a handle 2 rotatably disposed on the mounting portion 101 , a driving member 8 disposed on the handle 2 , and rotatably disposed in the outer tube 1 through the handle 2 .

[0056] In the above scheme, there are two handles 2, which are arranged longitudinally. The upper handle 2 is a fixed handle, and the lower handle 2 can rotate. The lower handle 2 is connected to the screw 802 through the vertical plate 804 and the connecting plate 803. When the handle 2 is rotated, the screw 801 can be driven to rotate.

[0057] Furthermore, the telescopic rod 4 has a lifting end 802, and the driving member 8 includes: a screw 801, which is rotatably arranged in the outer tube 1, one end of the screw 801 passes through the bottom surface of the mounting portion 101, and the other end of the screw 801 extends into the telescopic rod 4; a lifting end 802, which is threadedly connected to the screw 801, and the lifting end 802 slides against the bottom surface of the telescopic rod 4, and the lifting end 802 is used to push the telescopic rod 4 to move; a connecting plate 803, which is arranged on one end of the screw 801 extending out of the mounting portion 101; a vertical rod 804, which is arranged on the connecting plate 803, and the vertical rod 804 is arranged on the handle 2, and the handle 2 drives the screw 801 to rotate.

[0058] In the above scheme, a circular hole is opened on the bottom surface of the mounting portion 101, one end of the screw 801 passes through the circular hole and extends out of the mounting portion 101, the connecting plate 803 is located at the bottom of the mounting portion 101, and is fixedly connected to the end of the screw 801 located on the outside of the mounting portion 101, and secondly, the vertical rod 804 is inserted into the handle 2. When the handle 2 rotates, the handle 2 will drive the connecting plate 803 to rotate, thereby realizing the rotation of the screw 801. At this time, the lifting end 802 threadedly connected to the screw 801 in the outer tube 1 will move up or down along the axial direction of the outer tube 1, and the telescopic rod 4 as a whole will be fine-tuned in the axial direction, thereby improving the accuracy and portability of the operation.

[0059] Furthermore, a slide groove 102 is provided in the outer tube 1 along the axial direction, and further includes: a slide bar 5, which is provided on the telescopic rod 4 along the axial direction of the telescopic rod 4, and the slide bar 5 is slidably provided in the slide groove 102. The slide groove 102 is only provided in the outer tube 1, and the slide bar 5 is only provided on the hollow tube 401 with the largest diameter. It should be noted that when the telescopic rod 4 is retracted, adjacent hollow tubes 401 can slide against each other, so as to facilitate the screw connection with the working end cap 6.

[0060] Furthermore, the telescopic rod 4 includes a plurality of hollow tubes 401 with successively decreasing diameters, and adjacent hollow tubes 401 slide relative to each other. The use of the hollow tubes 401 can reduce the overall weight of the telescopic rod 4, because the overall length of the insulating operating rod after extension is long, and the use of the hollow tubes 401 can effectively reduce the weight, and also facilitate the user to lift and control the insulating operating rod.

[0061] Reference Figure 8~Figure 11Furthermore, the mounting seat 601 also has a threaded hole 604, and the hollow tube 401 with the smallest diameter has a through hole 402, which is connected to the threaded hole 604; and further includes: a bolt 7, which passes through the threaded hole 604 and the through hole 402 in sequence, and is screwed to the threaded hole 604. The working end cap 6 is connected to the top of the telescopic rod 4 through the bolt 7, which is convenient for replacing different types of working end caps 6 to adapt to different working scenes and improve the applicability of the device.

[0062] Furthermore, it also includes: a rubber sleeve 3, which is sleeved on the outer tube 1; and a plurality of convex strips 9, which are arranged at intervals on the rubber sleeve 3. The rubber operating rod is lifted with both hands, and the user can hold the handle 2 with one hand and the rubber sleeve 3 with the other hand, so that the user can stably control the insulating operating rod. In addition, when the insulating operating rod needs to be lifted, the handle 2 can also be held with both hands. It should be noted that there are two handles 2, which are longitudinally arranged along the axis direction of the mounting portion 101, one of which is fixedly arranged, and the other is rotatably connected to the mounting portion 101. The rotatably arranged handle 2 is used to control the rotation of the screw 801, so that the operator can control the insulating operating rod.

[0063] Furthermore, it also includes: a limiter, which is detachably arranged on the telescopic rod 4. After the telescopic rod 4 is extended, the limiter limits and fixes each hollow tube 401. The limiter can be a plug block or a latch. After the telescopic rod 4 is extended, two adjacent hollow tubes 401 are limited and fixed. When the telescopic rod 4 is retracted, the latch can be removed without affecting the rotation of adjacent telescopic rods 4, so that the working end cap 6 is conveniently screwed to the outer tube 1.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
