Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, specifically to a connecting fitting for assembling suspension insulators. Background Technology

[0002] Suspension insulators are generally constructed by gluing insulating components (such as porcelain or glass components) and metal fittings (such as steel feet, iron caps, and flanges) together with adhesive or mechanically clamping them together. Insulators are widely used in power systems and are generally external insulators, operating under atmospheric conditions. Overhead transmission lines, busbars in power plants and substations, and the external energized conductors of various electrical equipment must be supported by insulators to insulate them from the ground (or grounded objects) or other conductors with a potential difference.

[0003] The existing suspension insulator installation is a high-altitude operation, using screws for fixing. When performing emergency repairs on insulators at height, the installation time of the original insulators is relatively long, which increases the difficulty for workers to work at height. When installing insulators, different shapes of insulators require different installation distances, and different width plates are needed during installation, resulting in waste of resources. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a connecting hardware for assembling suspension insulators, which solves the technical problems of existing suspension insulator installation being a high-altitude operation, using screws for fixing, and the long installation time of the original insulators during high-altitude emergency repairs, which increases the difficulty of high-altitude operations for workers. In addition, the different shapes of insulators and the different installation distances between insulators require the use of plates of different widths during installation, resulting in resource waste.

[0005] According to one aspect, at least one embodiment of the present invention provides a connecting fitting for a suspension insulator assembly, comprising: an insulator one, an mounting base one fixedly mounted on the top end of the insulator one, a mounting base two fixedly mounted on the bottom end of the insulator one, and an insulator two fixedly mounted on the side end of the insulator one;

[0006] The device plate is fixedly installed on the upper end of the mounting base. A first mounting hole is fixedly opened on the outer side of the upper end of the device plate. A housing is fixedly installed on the upper end of the device plate, and sliding grooves are fixedly opened on both sides inside the housing. A moving groove is fixedly opened on the front of the upper end of the housing. A fixing rod is fixedly connected inside the housing.

[0007] For example, in a connection fitting for a suspension insulator assembly provided in at least one embodiment of the present invention, a telescopic spring rod is fixedly installed at the lower end of the fixed rod, sliding blocks are fixedly installed on both sides of the upper end of the fixed rod, and a pressing plate is fixedly installed at the front end of the fixed rod.

[0008] For example, in at least one embodiment of this utility model, a connecting fitting for assembling a suspension insulator further includes: a fixing groove fixedly connected to the top of the fixing rod, and a connecting plate installed on the upper end of the fixing groove; a second mounting hole fixedly opened on the upper end of the connecting plate; a connecting plate fixedly installed on the top surface of the connecting plate, and a third mounting hole fixedly opened on the upper end of the connecting plate; a rotating plate fixedly installed on the top surface of the connecting plate, and a support plate installed inside the rotating plate; a connecting rod inserted through the upper end of the support plate; a fixing hole one fixedly opened on the upper end of the support plate; a bracket fixedly connected to the outside of the support plate, and a fixing hole two fixedly opened inside the bracket, having the same structure as the mounting base two; a fixed connection is formed between the bottom surface of the device plate and the top surface of the mounting base one; and the number of the first mounting holes is four.

[0009] For example, in a connection fitting for assembling a suspension insulator provided in at least one embodiment of the present invention, the first mounting base and the second mounting base have the same structure, the bottom surface of the device plate and the top surface of the first mounting base are fixedly connected, and the number of the first mounting holes is four.

[0010] For example, in a connection fitting for a suspension insulator assembly provided in at least one embodiment of the present invention, the sliding block is symmetrically installed on the left and right sides of the fixed rod with the fixed rod as the central base, the pressing plate and the moving groove on the outer shell are interlocked, and the pressing plate is a triangular structure.

[0011] For example, in a connection fitting for assembling a suspension insulator provided in at least one embodiment of the present invention, the fitting further includes: grooves fixedly opened on both sides inside the fixing groove; the second mounting hole on the connecting plate and the third mounting hole on the connecting plate being aligned and connected; and the support plate being rotatably connected to the rotating plate through a connecting rod.

[0012] For example, in at least one embodiment of the present invention, a connection fitting for assembling a suspension insulator further includes: the support plate is L-shaped and four fixing holes are evenly provided on the support plate; the bracket is triangular; the fixing holes are aligned and connected with each other, and the fixing holes form a flange connection.

[0013] The beneficial effects of the embodiments of this utility model are as follows:

[0014] In this invention, the original screw installation is replaced with a quick-connect installation. A pressing plate moves the fixing rod downwards via a telescopic spring rod, increasing the length of the fixing rod to interlock with the fixing slot, allowing for rapid insulator installation. This quick-connect structure enables workers to quickly install and replace insulators with one hand, increasing overall installation convenience and reducing work time. Furthermore, the device includes multiple fixing holes (two types) on the bracket and multiple fixing holes (one type) on the top support plate of the insulator. Different sized insulators are installed via flange connections between fixing holes (one and two types). The installation distance between insulators can be adjusted by adjusting the installation distance between the holes, reducing waste of equipment resources. Attached Figure Description

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-3As shown, it illustrates a connection fitting for a suspension insulator assembly in one embodiment of the present invention, including: an insulator 1, an mounting base 2 fixedly installed at the top of the insulator 1, a mounting base 3 fixedly installed at the bottom of the insulator 1, and an insulator 4 fixedly installed at the side of the insulator 1.

[0029] Device plate 5 is fixedly installed on the upper end of mounting base 2. A first mounting hole 6 is fixedly opened on the outer side of the upper end of device plate 5. A housing 7 is fixedly installed on the upper end of device plate 5. Sliding grooves 8 are fixedly opened on both sides inside the housing 7. A moving groove 9 is fixedly opened on the front of the upper end of housing 7. A fixing rod 10 is fixedly connected inside the housing 7.

[0030] For example, such as Figure 3 As shown, a telescopic spring rod 11 is fixedly installed at the lower end of the fixed rod 10, sliding blocks 12 are fixedly installed on both sides of the upper end of the fixed rod 10, and a pressing plate 13 is fixedly installed at the front end of the fixed rod 10.

[0031] For example, such as Figure 2 As shown, mounting base 12 and mounting base 23 have the same structure. The bottom surface of device plate 5 and the top surface of mounting base 12 are fixedly connected. The number of first mounting holes 6 is four.

[0032] For example, such as Figure 3 As shown, the sliding groove 8 is symmetrically installed on the left and right sides of the housing 7 with the interior of the housing 7 as the center base. The sliding groove 8 and the sliding block 12 form a sliding connection. The fixed rod 10 moves up and down through the telescopic spring rod 11.

[0033] For example, such as Figure 3 As shown, the sliding block 12 is symmetrically installed on the left and right sides of the fixed rod 10 with the fixed rod 10 as the central base. The pressing plate 13 and the moving groove 9 on the outer shell 7 are interlocked. The pressing plate 13 has a triangular structure.

[0034] In some examples, the device plate 5 is installed on the mounting bases (mounting base 1 2, mounting base 2 3) at both ends of the insulator 1. The upper end of the device plate 5 has evenly spaced first mounting holes 6. Bolts are used to fasten the device plate 5 to the mounting bases by passing through the first mounting holes 6. A housing 7 is installed on the upper end of the fixed device plate 5. Sliding grooves 8 are formed on both sides of the inside of the housing 7, and a moving groove 9 is formed at the front end of the housing 7. A pressing plate 13 is fixed to the front end of the fixing rod 10, and sliding blocks 12 are fixed to both sides of the fixing rod 10. A telescopic spring rod 11 is added to the lower end of the fixing rod 10. The sliding blocks 12 on both sides of the fixing rod 10 are embedded into the sliding grooves 8 inside the housing 7 to form a sliding connection. Simultaneously, the front end of the fixing rod 10... The pressing plate 13 passes through the moving groove 9 at the front end of the outer casing 7. When insulator 1 needs to be installed, the worker aligns the top of the fixing rod 10 with the fixing groove 14 at the target position, and then presses down the pressing plate 13 at the front end of the fixing rod 10. The pressing plate 13 moves down along the moving groove 9, and the fixing rod 10 slides down under the guidance of the sliding groove 8 through the sliding blocks 12 on both sides. The telescopic spring rod 11 is compressed. When the top of the fixing rod 10 contacts the bottom of the fixing groove 14, the worker releases the pressing plate 13. The compressed telescopic spring rod 11 releases its elasticity and pushes the fixing rod 10 upward until its top springs in and is inserted into the fixing groove 14, completing the insertion connection with the fixing groove 14, thereby fixing the insulator 1.

[0035] like Figures 4-5 As shown, this invention illustrates a connecting fitting for assembling a suspension insulator according to another embodiment of the present invention, comprising: a fixing groove 14 fixedly connected to the top of a fixing rod 10, and a connecting plate 15 installed on the upper end of the fixing groove 14; a second mounting hole 16 fixedly opened on the upper end of the connecting plate 15; a connecting plate 17 fixedly installed on the top surface of the connecting plate 15, and a third mounting hole 18 fixedly opened on the upper end of the connecting plate 17; a rotating plate 19 fixedly installed on the top surface of the connecting plate 17, and a support plate 20 installed inside the rotating plate 19; a connecting rod 21 inserted through the upper end of the support plate 20; a first fixing hole 22 fixedly opened on the upper end of the support plate 20; a bracket 23 fixedly connected to the outer side of the support plate 20, and a second fixing hole 24 fixedly opened inside the bracket 23.

[0036] For example, such as Figure 4 As shown, grooves are fixedly opened on both sides inside the fixing groove 14, the second mounting hole 16 on the connecting plate 15 and the third mounting hole 18 on the connecting plate 17 are aligned and connected, and the support plate 20 is rotatably connected to the rotating plate 19 through the connecting rod 21.

[0037] For example, such as Figure 5 As shown, the support plate 20 is L-shaped and has four fixing holes 22 evenly distributed on it. The bracket 23 is triangular in shape. The fixing holes 22 and 24 are aligned and connected, and the fixing holes 22 and 24 form a flange connection.

[0038] In some examples, after the insulator is installed in place, a connecting plate 15 is fixed on its fixing groove 14. The connecting plate 15 has a second mounting hole 16, and the connecting plate 17 has a third mounting hole 18. Bolts are used to connect the connecting plate 15 and the connecting plate 17 through the second mounting hole 16 and the third mounting hole 18, thus securing the connecting plate 15 and the connecting plate 17. A rotating plate 19 is fixedly installed on the connecting plate 17. A support plate 20 is hinged to the rotating plate 19 via a connecting rod 21, allowing the support plate 20 to rotate relative to the rotating plate 19. The support plate 20 is L-shaped. The upper end of the long arm, i.e. the long side of the L-shape, is evenly provided with multiple fixing holes 1 22, and the bracket 23 is provided with multiple fixing holes 24. The long arm of the support plate 20 is aligned with the bracket 23, and the two are fastened together by bolts passing through the selected fixing holes 1 22 and fixing holes 24. When it is necessary to install insulators of different shapes or sizes, the relative position height or angle between the two can be adjusted by matching and connecting different fixing holes 1 22 on the long arm of the support plate 20 with different fixing holes 24 on the bracket 23, so as to achieve installation adaptation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
