Description

Technical Field

[0001] This utility model relates to the field of power detection and protection technology, specifically to an insulating shielding cover for power detection. Background Technology

[0002] An insulating shield is a protective device made of insulating material. It opens and closes using its own elasticity and toughness. It is mainly used to shield live conductors or non-live conductors. It can effectively prevent workers from accidentally touching live conductors or causing short circuits in equipment during work. It can also block rainwater and reduce the risk of electric shock.

[0003] Existing insulating shields require workers to use clamps to position them and then control their unfolding from a distance using the clamps to attach them to the outside of the live conductor to form an insulating barrier. This method effectively prevents workers from coming into contact with the live conductor while using the shield. However, during the use of the existing technology, the inventors found that installing the shield using clamps is cumbersome and time-consuming. Furthermore, the clamps raise the center of gravity of the workers when manipulating the shield, making it more difficult to operate and increasing the risk of misalignment and installation failure. Utility Model Content

[0004] Based on the above description, this utility model provides an insulating shield for power testing, which solves the problem that when existing insulating shields are used with the aid of clamps, the center of gravity of the operator is extended, which increases the difficulty of operation when the shield is fastened and installed, and easily leads to misalignment and installation failure.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An insulating shield for power detection includes a shield and a cylinder integrally formed on the surface of the shield. The shield and the cylinder are symmetrically split along the opening side. The shield is automatically closed through a sealing end. Symmetrically distributed clamps are installed on the outer side of the shield. The clamps extend away from the split of the shield. The clamps control the shield to unfold about the sealing end.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the opening side of the protective cover is provided with a slit, which extends to the sealing end of the protective cover and penetrates the cylinder. The slit coincides with the center of the protective cover and evenly divides the cylinder.

[0008] Furthermore, a positioning block is fixedly connected to the outer side of the protective cover, and the positioning blocks are symmetrically distributed with the cut as the center.

[0009] Furthermore, a baffle is integrally formed at the end of the positioning block away from the protective cover, and the area of ​​the baffle is larger than that of the positioning block.

[0010] Furthermore, the clamp includes a mounting plate, a slot, a first curved portion and a second curved portion. The slot is located at the center of one end of the mounting plate. The mounting plate is inserted into the outside of the positioning block through the slot. The slot is adapted to the size of the positioning block.

[0011] Furthermore, the mounting plate is arc-shaped on the side near the protective cover, and its axis coincides with the axis of the protective cover. The arc-shaped side of the mounting plate is completely in contact with the surface of the protective cover, and the side of the mounting plate away from the protective cover is in contact with the baffle.

[0012] Furthermore, the first curved portion is integrally formed at the end of the mounting plate away from the positioning block, and the first curved portion bends toward the sealing end of the cover, and the first curved portion completely fits the surface and edge of the sealing end of the cover.

[0013] Furthermore, the second curved portion is integrally formed at the end of the first curved portion away from the mounting plate, the second curved portion is perpendicular to the sealing end of the cover, and the end of the second curved portion away from the mounting plate is bent toward the outside of the cover.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] This invention utilizes a symmetrically split shield and cylinder, along with a clamp directly integrated on the outside of the shield. This eliminates the need for positioning and repeated adjustments required by traditional external clamps, bringing the point of force application closer to the shield body. This significantly reduces the operating torque and avoids swaying or misalignment caused by the extended center of gravity of the clamp. At the same time, the elastic reset feature allows the shield to be quickly opened and closed without relying on external clamps, simplifying the operation and significantly improving installation efficiency and accuracy.

[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] Please see Figure 1-3 The present invention provides an insulating shield for power testing, comprising a shield 1 and a cylinder 11 integrally formed on the surface of the shield 1. The shield 1 and the cylinder 11 are symmetrically split along the opening side. The shield 1 is automatically closed by a sealing end. Symmetrically distributed clamps 3 are installed on the outer side of the shield 1. The clamps 3 extend away from the split of the shield 1. The clamps 3 control the shield 1 to unfold around the sealing end as the axis.

[0024] Please see Figure 1 The protective cover 1 has a slit 12 on its open side, which extends to the sealing end of the protective cover 1 and penetrates the cylinder 11. The slit 12 coincides with the center of the protective cover 1 and evenly divides the cylinder 11. The slit 12 extends along the open side of the protective cover 1 to the sealing end, so that the split structure is evenly and symmetrically distributed, ensuring that the protective cover 1 is subjected to balanced force when it is unfolded. The sealing end of the protective cover 1 can control the closing direction of the protective cover 1, further enhancing the elastic reset capability of the protective cover 1 and avoiding the fastening deviation of the protective cover 1. The sealing end of the protective cover 1 can directly isolate the live conductor from the hands of the workers, improving the adaptive capability to live conductors.

[0025] Please see Figure 2A positioning block 2 is fixedly connected to the outer side of the protective cover 1. The positioning blocks 2 are symmetrically distributed around the cut 12. A baffle 21 is integrally formed at the end of the positioning block 2 away from the protective cover 1. The area of ​​the baffle 21 is larger than that of the positioning block 2. The positioning blocks 2 are symmetrically distributed around the cut 12 to provide a precise installation reference for the clamping handle 3, ensuring that the direction of clamping force is consistent with the split axis of the protective cover 1, preventing the protective cover 1 from deforming or misaligning due to the position displacement of the clamping handle 3 during operation, and enhancing installation stability. The baffle 21 has a larger area than the positioning block 2. By increasing the contact area with the clamping handle 3, a stable support surface is formed, preventing the clamping handle 3 from slipping or shifting during the application of force. At the same time, it disperses the local stress during operation, reduces the risk of structural damage, and increases the stability of the opening and closing operation of the protective cover 1.

[0026] Please see Figure 2 The clamp 3 includes a mounting plate 31, a slot 32, a first curved portion 33, and a second curved portion 34. The slot 32 is located at the center of one end of the mounting plate 31. The mounting plate 31 is inserted into the outer side of the positioning block 2 through the slot 32. The slot 32 is adapted to the size of the positioning block 2. The side of the mounting plate 31 near the protective cover 1 is arc-shaped, and its axis coincides with the axis of the protective cover 1. The arc-shaped side of the mounting plate 31 is completely in contact with the surface of the protective cover 1. The side of the mounting plate 31 away from the protective cover 1 is in contact with the baffle 21. The slot 32 and the positioning block 2 are adapted to each other. The design allows the clamp 3 to be quickly installed or removed from the outside of the cover 1 by inserting or pulling, simplifying the assembly process and eliminating the need for additional fasteners. The plug-in structure ensures a tight connection between the clamp 3 and the cover 1, preventing operational failure caused by loosening. The arc-shaped design of the mounting plate 31 fits perfectly with the surface of the cover 1 and the baffle 21, ensuring that the force on the clamp 3 is evenly transmitted to the body of the cover 1, avoiding deformation caused by local stress concentration. At the same time, the arc-shaped contact surface enhances the coordinated movement effect between the clamp 3 and the cover 1, making the operation smoother.

[0027] Please see Figure 1 The first curved part 33 is integrally formed on the end of the mounting plate 31 away from the positioning block 2. The first curved part 33 bends toward the sealing end of the cover 1. The first curved part 33 completely fits the surface and edge of the sealing end of the cover 1. The first curved part 33 fits the surface and edge of the sealing end of the cover 1, forming a multi-point force structure. When the clamp handle 3 is operated to unfold the cover 1, the wrapping effect of the curved part on the sealing end can accurately control the cover 1 to unfold elastically with the sealing end as the axis, preventing the split side displacement caused by uneven force application and ensuring the accuracy of the fastening alignment.

[0028] Please see Figure 1The second curved portion 34 is integrally formed at the end of the first curved portion 33 away from the mounting plate 31. The second curved portion 34 is perpendicular to the sealing end of the cover 1. The end of the second curved portion 34 away from the mounting plate 31 bends towards the outside of the cover 1. The second curved portion 34 is perpendicular to the sealing end of the cover 1 and bends outward to form an ergonomic grip portion, which increases the operating torque and reduces the applied force. The design of the end of the second curved portion 34 bending outward can guide the operator to grip naturally and avoid the fingers slipping, thus taking into account both the ease of operation and the safety of operation.

[0029] When the protective cover 1 needs to be installed, the worker pinches the two clamps 3 and applies force to the clamps 3. The clamps 3 are centered on the sealing end of the protective cover 1, so that the protective cover 1 and the cylinder 11 are unfolded through the slit 12. The worker installs the unfolded protective cover 1 and the cylinder 11 on the outside of the live conductor and releases the clamps 3. Under the elastic reset action of the sealing end of the protective cover 1, the unfolded protective cover 1 and the cylinder 11 automatically close and wrap around the outside of the live conductor, thus isolating the live conductor.
