This utility model also relates to a power construction tool, specifically a portable power insulating operating rod. Background Technology

[0002] An electric insulated operating rod, also known as an electric insulated operating bar, electric insulated pull rod, or electric link bar, is a power construction tool used for power operations. It is mainly used for handling foreign objects on live power lines and connecting ground wires at high altitudes, thus avoiding the risk of electric shock caused by direct contact with high-voltage electricity.

[0003] Existing power insulation operating rods mainly consist of a telescopic insulation rod mechanism and a working head. The telescopic insulation rod mechanism includes at least two insulation rod sections that are nested together in sequence. However, the telescopic position of the existing telescopic insulation rod mechanism is not fixed and is prone to slippage during use, which can lead to unexpected contraction or extension of the telescopic insulation rod mechanism. This will seriously affect the accuracy of operation and safety of construction personnel during power construction. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a telescopic insulating rod mechanism and a portable power insulating operating rod, thereby improving the operational accuracy and safety of construction personnel.

The pressing and locking mechanism includes an open clamp and a transverse dividing slit on the open clamp. The portion of the open clamp located below the transverse dividing slit is fixed to the upper end of the lower insulating rod section in the adjacent two insulating rod sections. The portion of the open clamp located above the transverse dividing slit is mounted on the upper insulating rod section in the adjacent two insulating rod sections via the pressing and locking member. When the pressing and locking member is in the unlocked state, the adjacent two insulating rod sections can slide relative to each other to achieve telescopic adjustment.

The first part includes an upper insulating rod that allows adjacent insulating rods to slide relative to each other; the second part includes a screw that passes through and is threaded to two upper connecting lugs in the open clamp, a connecting post that is threaded to the screw, and an eccentric handle that is hinged to the connecting post. When the eccentric handle is locked, it can clamp the upper insulating rod in the two adjacent insulating rods inward to fix the two adjacent insulating rods together. When the eccentric handle is unlocked, it can release the upper insulating rod in the two adjacent insulating rods outward to allow the two adjacent insulating rods to slide relative to each other.

[0007] As a further limitation on the above-mentioned telescopic insulating rod mechanism, a rubber pad is fitted on one end of the threaded rod near the connecting ring; a rubber pad is fitted on the screw at the position between the upper connecting lug plate and the connecting post on the side near the connecting post.

[0009] As another limitation of the above-mentioned telescopic insulating rod mechanism, the outer surface of the pressing and locking mechanism is coated with reflective paint, and the outer surface of each section of the insulating rod is coated with reflective paint.

[0010] This utility model also provides a portable power insulation operating rod, including any of the above-mentioned telescopic insulation rod mechanisms, a quick-connect connector disposed on the top of the telescopic insulation rod mechanism, and a working head detachably connected to the top of the quick-connect connector.

[0011] As a limitation of the aforementioned portable power insulation operating rod, the quick-connect connector is mounted on the top of the telescopic insulation rod mechanism via a hinge seat; the hinge seat includes a U-shaped plate fixed to the top of the telescopic insulation rod mechanism, a connecting plate inserted into the opening of the U-shaped plate, a bolt passing through the U-shaped plate and the connecting plate and threadedly connected to the U-shaped plate and the connecting plate, and a fastening nut threadedly connected to the bolt; the top of the connecting plate is fixedly connected to the bottom of the quick-connect connector.

[0012] As a further definition of the aforementioned portable power insulation operating rod, the working head is a grounding hook, and a voltage testing mechanism is detachably connected to the top of the grounding hook.

[0015] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0016] (1) In the telescopic insulating rod mechanism of this utility model, a pressing and locking mechanism is provided between each two adjacent insulating rod sections. The pressing and locking mechanism has an ingenious structural design. The open clamp is provided with a transverse partition and a pressing and locking component is provided in conjunction. The part of the open clamp located above the transverse partition can be locked to the upper insulating rod in the two adjacent insulating rod sections by the pressing and locking component. The part of the open clamp located below the transverse partition is fixed to the upper end of the lower insulating rod in the two adjacent insulating rod sections. When in use, pressing or lifting the pressing and locking component can independently control the part of the open clamp located above the transverse partition to clamp inward or loosen outward.

When using this portable power insulation operating rod for power construction, the telescopic insulation rod mechanism will not slip, thus preventing accidental retraction or extension. This effectively improves the accuracy of operation and safety of construction personnel. When not in use, the telescopic insulation rod mechanism can be retracted for easy carrying and use. In addition, the quick-connect fittings can be quickly attached and detached from the working head, improving the convenience of use.

[0022] (7) The quick-connect type connector in the portable power insulation operating rod of this utility model is mounted on the telescopic insulation rod mechanism through a hinge seat. The angle between the working head and the telescopic insulation rod mechanism can be adjusted by adjusting the hinge seat. The angle between the working head and the telescopic insulation rod mechanism can be adjusted according to actual usage needs, which can improve the convenience of operation.

[0023] (8) The portable power insulation operating rod of this utility model is equipped with a voltage testing mechanism and the working head is a grounding hook. When carrying out power construction, the construction personnel can first use the voltage testing mechanism to test for electricity. After confirming that there is no electricity, they can directly use the grounding hook to hang the ground wire, realizing the continuous operation from voltage testing to hanging the ground wire, which can significantly improve the construction efficiency of power construction.

[0024] (9) The portable power insulation operating rod of this utility model is provided with a foldable ground wire winding bracket. When it is necessary to store the ground wire, the foldable ground wire winding bracket can be opened to store the ground wire. When it is not necessary to store the ground wire, the foldable ground wire winding bracket can be folded up.

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0036] Example 1: A telescopic insulating rod mechanism

[0037] like Figure 1-3 As shown, this embodiment 1 includes at least two insulating rods 1 that are sequentially nested together. Each pair of adjacent insulating rods 1 is provided with a pressing and locking mechanism that can lock the adjacent two insulating rods 1 together. The structure of the at least two insulating rods 1 nested together is a conventional telescopic rod structure. The insulating rods 1 can be made of insulating materials such as epoxy resin or glass fiber and epoxy resin composite materials.

[0038] The press-locking mechanism includes an open clamp 2 and a transverse dividing slit 3 on the open clamp 2. The portion of the open clamp 2 located below the transverse dividing slit 3 is fixed to the upper end of the lower insulating rod 1 of the two adjacent insulating rod sections 1. The portion of the open clamp 2 located above the transverse dividing slit 3 is mounted on the upper insulating rod 1 of the two adjacent insulating rod sections 1 via a press-locking member. When the press-locking member is in the unlocked state, a gap is left between the portion of the open clamp 2 located above the transverse dividing slit 3 and the upper insulating rod 1 of the two adjacent insulating rod sections 1, allowing the two adjacent insulating rod sections 1 to slide relative to each other. When the press-locking member is in the unlocked state, the two adjacent insulating rod sections 1 can slide relative to each other to achieve telescopic adjustment. When the press-locking member is in the locked state, the two adjacent insulating rod sections 1 can be locked together. Specifically, in this embodiment 1, the open clamp 2 is made of metal materials such as aluminum alloy and stainless steel or high-strength plastic materials, and the length of the transverse dividing slit 3 accounts for one-third of the circumference of the open clamp 2.

[0039] The pressing and locking component has one of the following structures: a) The first structure of the pressing and locking component includes a threaded rod 4 that passes through and is threadedly connected to two upper connecting ear plates 11 in the open clamp 2, a connecting ring 5 fixed to the end of the threaded rod 4, an eccentric handle 7 hinged to the connecting ring 5 via a hinge shaft, and an adjusting nut 6 threadedly connected to the threaded rod 4 at the end away from the connecting ring 5; when the eccentric handle 7 is in the locked state, it can cause the part of the open clamp 2 located above the transverse partition 3 to clamp the upper insulating rod 1 of the two adjacent insulating rods 1 inward so that the two adjacent insulating rods 1 are fixed together; when the eccentric handle 7 is in the unlocked state, it can cause the part of the open clamp 2 located above the transverse partition 3 to release the upper insulating rod 1 of the two adjacent insulating rods 1 outward so that the two adjacent insulating rods 1 can slide relative to each other. b) A second structure of the pressing and locking component: including a screw that passes through and is threadedly connected to two upper connecting ear plates in the open clamp, a connecting post that is threadedly connected to the screw, and an eccentric handle that is hinged to the connecting post; when the eccentric handle is in the locked state, it can cause the part of the open clamp located above the transverse partition to clamp the upper insulating rod of the two adjacent insulating rods inward so that the two adjacent insulating rods are fixed together; when the eccentric handle is in the unlocked state, it can cause the part of the open clamp located above the transverse partition to release the upper insulating rod of the two adjacent insulating rods outward so that the two adjacent insulating rods can slide relative to each other. Specifically, in this embodiment, in the first structure of the pressing and locking component, the hinge shaft on the eccentric handle 7 is eccentrically positioned. The distance between the outer periphery of the part of the eccentric handle 7 that contacts the connecting ring 5 and the rotation center of the eccentric handle 7 gradually increases. Here, the position where the distance between the outer periphery of the part of the eccentric handle 7 that contacts the connecting ring 5 and the rotation center of the eccentric handle 7 is the smallest is defined as the low position of the eccentric handle 7, and the position where the distance between the outer periphery of the part of the eccentric handle 7 that contacts the connecting ring 5 and the rotation center of the eccentric handle 7 is the largest is defined as the high position of the eccentric handle 7. When the eccentric handle 7 is in the low position, the portion of the open clamp 2 located above the transverse dividing seam 3 will not... An inward clamping force is applied to the upper insulating rod 1 of two adjacent insulating rod sections 1. When the eccentric handle 7 is in the high position, the portion of the open clamp 2 located above the transverse dividing seam 3 applies an inward clamping force to the upper insulating rod 1 of the two adjacent insulating rod sections 1, thereby firmly locking and fixing the upper insulating rod 1 of the two adjacent insulating rod sections 1. Here, it is defined that when the eccentric handle 7 is rotated from the low position to the high position, the eccentric handle 7 is in the locked state, that is, the pressing locking component is in the locked state; when the eccentric handle 7 is rotated from the high position to the low position, the eccentric handle 7 is in the unlocked state, that is, the pressing locking component is in the unlocked state. In the second structure of the pressing locking component, the working principle of the eccentric handle 7 is the same as that in the first structure of the pressing locking component, so it will not be described again here.To improve the reliability and practicality of the structure in Embodiment 1, when the pressing and locking component adopts the first structure, a rubber pad 10 is fitted on the end of the threaded rod 4 near the connecting ring 5. When the pressing and locking component adopts the second structure, a rubber pad is fitted on the screw at the position between the upper connecting ear plate and the connecting post on the side near the connecting post. Correspondingly, in both structures of the pressing and locking component, an insertion groove adapted to the rubber pad 10 is provided on the upper connecting ear plate 11 of the open clamp 2 near the rubber pad 10, and the rubber pad 10 is inserted into the insertion groove. The rubber pad 10 is a circular rubber pad with an arc-shaped groove on the circular rubber pad, and the front end of the eccentric handle 7 can rotate on the arc-shaped groove.

[0040] Furthermore, in this embodiment 1, the open clamp 2 has one of the following structures: The first structure of the open clamp 2: The open clamp 2 has two upper connecting lugs 11 and two lower connecting lugs 12.

The second structure of the open clamp 2: The open clamp 2 has only two upper connecting lugs 11. The portion of the open clamp 2 located below the transverse dividing seam 3 is glued to the upper end of the lower insulating rod 1 in two adjacent insulating rod sections 1. Correspondingly, in this embodiment 1, the pressing locking mechanism has one of the following structures: The first structure of the pressing locking mechanism is as follows: Figure 1-3 As shown, the open clamp 2 in the press-locking mechanism adopts the first structure, the press-locking component adopts the first structure, and both the open clamp 2 and the eccentric handle 7 are made of metal materials such as aluminum alloy or stainless steel. A rubber pad 10 is fitted onto the end of the threaded rod 4 near the connecting ring 5 in the press-locking mechanism.

Figure 5 As shown, the third structure of the press-locking mechanism: the open clamp 2 in the press-locking mechanism adopts the second structure, while the press-locking component adopts the first structure. Both the open clamp 2 and the eccentric handle 7 are made of metal materials such as aluminum alloy or stainless steel. In the press-locking component, a rubber pad 10 is fitted on the end of the threaded rod 4 near the connecting ring 5. Figure 6As shown, the fourth structure of the press-locking mechanism is as follows: the open clamp 2 in the press-locking mechanism adopts the second structure, the press-locking component adopts the second structure, the open clamp 2 and the eccentric handle 7 are both made of metal materials such as aluminum alloy or stainless steel, and a rubber pad 10 is provided on the screw 21 in the press-locking component at the position between the upper connecting ear plate and the connecting post 22 on the side near the connecting post 22.

The telescopic insulating rod mechanism has the same structure as the telescopic insulating rod mechanism in embodiment 1, so it will not be described again here.

When ground wire winding is not required, the foldable handles can be folded up and kept parallel to the telescopic insulating rod mechanism. When ground wire winding is required, the foldable handles are adjusted to a position perpendicular to the telescopic insulating rod mechanism.

[0047] The lighting mechanism includes an arc-shaped connecting plate 19 inserted into a quick-connect connector 15 and a high-intensity lighting lamp 20 fixed on the arc-shaped connecting plate 19.
