Description

Technical Field

[0001] The utility model relates to the technical field of electric power fittings, in particular to an electric power fitting which is convenient to install. Background Art

[0002] Power fittings are metal accessories that connect and combine various devices in the power system and play a role in transmitting mechanical loads, electrical loads and providing some protection. According to their functions and structures, they can be divided into suspension clamps, tension clamps, UT clamps, connecting fittings, etc. The right-angle hanging plates in connecting fittings are mainly used in overhead power lines or substations to connect conductors, lightning arrester clamps to insulators or to connect insulators, lightning arrester clamps to pole towers.

[0003] Some problems may occur during the installation of the existing right-angle hanging plate. The existing right-angle hanging plate is generally a simple structure formed in one piece. When the insulator connector is inserted and connected through by bolts, the insertion direction of the insulator connector is constant due to the fixed structure of the right-angle hanging plate. It is inconvenient for workers to observe from above whether the insulator connector is aligned with the openings on both sides of the right-angle hanging plate. At the same time, it is inconvenient for workers to adjust the observation angle because they are working at high altitudes, which makes it inconvenient for workers to align and insert the bolts. Therefore, based on the above problems, an electric hardware that is easy to install is proposed. Utility Model Content

[0004] The utility model aims to provide an easy-to-install electrical fitting to solve the problem that, due to the fixed structure of the right-angle hanging plate, the insertion direction of the insulator connector is constant, and it is inconvenient for workers to observe from above whether the insulator connector is aligned with the openings on both sides of the right-angle hanging plate. At the same time, it is inconvenient for workers to adjust the observation angle due to high-altitude operations, which makes it inconvenient for workers to align and insert the bolts.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An electric power fitting that is easy to install comprises a fixing part, a first connecting part is arranged on the right side of the fixing part, a rotating shaft is rotatably connected between the first connecting part and the guide hole of the fixing part, both ends of the rotating shaft are fixedly connected to limiting parts, damping elastic layers are fixedly connected to the outer end faces of the fixing part and the first connecting part, the damping elastic layers are fitted with each other, the damping elastic layer is arranged on the outer side of the rotating shaft, sliding grooves are opened on the upper and lower sides of the inner wall of the first connecting part, sliders are slidably connected to the inner sides of the sliding grooves, limiting blocks are fixedly connected between the outer end faces of the sliders, and a second connecting part is fixedly connected to the left end face of the limiting block.

[0007] Preferably, there are 4 slide grooves in total, and the slide grooves are symmetrically arranged front to back.

[0008] Preferably, the limit blocks on both sides are aligned front and back through a second connecting piece.

[0009] Preferably, a ferrule is fixedly connected to the upper end surface of the fixing member, a spring is fixedly connected to the inner wall of the groove of the ferrule, a screw is fixedly connected to the other end of the spring, a slot is provided on the lower end surface of the fixing member, a retaining ring is rotatably connected to the inner side of the slot, and a nut is fixedly connected to the lower end of the retaining ring.

[0010] Preferably, friction pads are fixedly connected to both sides of the inner wall of the fixing member.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by providing structures such as a fixing piece, a rotating shaft, a first connecting piece, and a limiting block, the first connecting piece can be rotated by the provided rotating shaft after the fixing piece is fixed. The insertion angle of the insulator connecting head can be adjusted by rotating the first connecting piece, so that the staff can observe whether the insulator connecting head is aligned with the limiting block. After the alignment is completed, the bolt is inserted, and the provided limiting block facilitates the alignment and insertion of the bolt. At the same time, a bolt and nut of a slightly smaller size can be installed for fixing, thereby realizing the ability of the right-angle hanging plate to change the insertion angle of the insulator connecting head for installation. The problem is solved that the insertion direction of the insulator connecting head is constant due to the fixed structure of the right-angle hanging plate, and the staff cannot observe from above whether the insulator connecting head is aligned with the openings on both sides of the right-angle hanging plate. At the same time, it is inconvenient for the staff to adjust the observation angle because they are working at high altitude, which makes it inconvenient for the staff to align and insert the bolt, thereby improving the practicality of the device.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0021] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction.

[0025] An electric power fitting convenient for installation comprises a fixing member 1, a first connecting member 3 is arranged on the right side of the fixing member 1, a rotating shaft 2 is rotatably connected to the guide hole of the first connecting member 3 and the fixing member 1, both ends of the rotating shaft 2 are fixedly connected to limiting members 4, the outer end surfaces of the fixing member 1 and the first connecting member 3 are fixedly connected to damping elastic layers 5, the damping elastic layers 5 are mutually attached, the damping elastic layers 5 are arranged on the outer side of the rotating shaft 2, the upper and lower sides of the inner wall of the first connecting member 3 are provided with sliding grooves 6, the inner sides of the sliding grooves 6 are slidably connected to sliders 7, the outer end surfaces of the sliders 7 are fixedly connected to limiting blocks 8, and the left end surface of the limiting block 8 is fixedly connected to the second connecting member 16 After the fixing member 1 is fixed, the first connecting member 3 can be rotated by the provided rotating shaft 2. The insertion angle of the insulator connector can be adjusted by rotating the first connecting member 3, so that the staff can observe whether the insulator connector is aligned with the limit block 8. After the alignment is completed, the bolt is inserted. The provided limit block 8 facilitates the alignment and insertion of the bolt. At the same time, a bolt and nut of a slightly smaller size can be installed for fixing, so that the right-angle hanging plate can change the insertion angle of the insulator connector for installation, and solves the problem that the insertion direction of the insulator connector is constant due to the fixed structure of the right-angle hanging plate, and it is inconvenient for the staff to observe the insulator connector from above. Whether the openings on both sides of the right-angle hanging plate are aligned, and at the same time, it is inconvenient for the workers to adjust the observation angle for high-altitude operations, which makes it inconvenient for the workers to align and insert the bolts, thereby improving the practicality of the device; there are a total of 4 slide grooves 6, and the slide grooves 6 are symmetrically arranged front and back, and multiple limit blocks 8 can be arranged between the multiple slide grooves 6; the limit blocks 8 on both sides are aligned front and back through the second connecting member 16, so that the guide holes of the limit blocks 8 are always aligned; the upper end surface of the fixing member 1 is fixedly connected with a ring 9, the inner wall of the groove of the ring 9 is fixedly connected with a spring 10, and the other end of the spring 10 is fixedly connected with a screw 11 A slot 12 is provided on the lower end surface of the fixing member 1, and a snap ring 13 is rotatably connected to the inner side of the slot 12, and a nut 14 is fixedly connected to the lower end of the snap ring 13. The fixed arrangement of the screw 11 and the nut 14 allows the staff to carry one less pair of parts during installation. At the same time, the fixed screw 11 and the nut 14 are convenient for installation. The elastic force of the spring 10 has the effect of an elastic washer when the screw 11 and the nut 14 are connected to each other; friction pads 15 are fixedly connected to both sides of the inner wall of the fixing member 1. When the right-angle hanging plate is fixed, the friction pad 15 can be simply fixed on the power accessory and then tightened by the screw 11 and the nut 14.

[0026] Working process: When it is necessary to use a right-angle hanging plate to connect the insulator, the staff inserts the fixing part 1 into the power accessory to be fixed, performs a simple fixation through the friction pad 15, aligns the socket and presses the screw 11, so that the screw 11 passes through the socket of the power accessory and fits with the nut 14. At this time, the nut 14 can be turned to move the screw 11 downward to fix the fixing part 1 at the power accessory. At the same time, the spring 10 is compressed and its elastic force also acts as an elastic gasket. The above operation enables the staff to install and fix the right-angle hanging plate more conveniently, and at the same time, they can carry one less pair of screws 11 and nuts 14. The insulator connector is inserted between the first connecting piece 3. At this time, the rotating shaft 2 is set The first connecting member 3 can be rotated, and the rotating first connecting member 3 drives the insulator connecting head to rotate at a certain angle, so that the staff can observe the alignment of the insulator connecting head and the limit block 8, and make fine adjustments according to the observed situation. At this time, the bolt is inserted into the limit block 8 and the insulator connecting head, so that the bolt is exposed from the guide hole of the limit block 8 on the other side. At this time, the bolt installation nut can be fixed (the limit block 8 is set to make the bolt easy to insert and align, and at the same time, compared with the existing right-angle hanging plate, the limit block 8 set can install slightly smaller bolts and nuts, which has stronger adaptability). Through the above-mentioned multiple operations, the right-angle hanging plate is easier to install and has stronger adaptability than the existing structure.
