Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 An insulating base for a surge arrester includes a support base 1. A fixing ring 5 is fixedly installed on the top of the support base 1 by screws. An upper fixing mechanism 3 is fixedly installed on both ends of the top of the support base 1 by screws. A strip groove 12 is opened on both sides of the bottom of the support base 1. A second fixing post 7 is fixedly installed in the strip groove 12. A connecting block 8 is rotatably sleeved on both ends of the second fixing post 7. A fixing base 2 is welded to the bottom of the connecting block 8. A locking cavity 9 is opened in the support base 1. A pin 6 is slidably installed in the locking cavity 9. A spring 61 is sleeved on the pin 6 and located in the locking cavity 9. A pin head 62 is provided at one end of the pin 6.

[0024] The arrester body 4 is inserted into the fixing ring 5, and a silicone sheet 51 is fixedly connected to the bottom of the fixing ring 5 with glue. The silicone sheet 51 is in contact with the top of the support base 1.

[0025] Meanwhile, the top of the support base 1 is provided with several drainage grooves 11, and the drainage grooves 11 have a certain inclination angle to facilitate drainage.

[0026] Meanwhile, a limiting hole 13 is provided at the center of the top of the support base 1, a positioning groove 14 is provided at the bottom of the limiting hole 13, and a grounding hole 15 is provided at the center of the bottom of the support base 1, and the grounding hole 15 is connected to the positioning groove 14. The grounding hole 15 facilitates the connection of the grounding wire of the surge arrester to the ground.

[0027] Meanwhile, the surge arrester body 4 is inserted into the limiting hole 13, and the positioning groove 14 opened in the limiting hole 13 facilitates the insertion of the surge arrester body 4 into the limiting hole 13 at the correct angle, which also facilitates the insertion of the pin head 62.

[0028] Meanwhile, the upper fixing mechanism 3 includes a connecting plate 32, one end of which is provided with a semi-circular sleeve 31, and the other end of the connecting plate 32 is rotatably sleeved on the first fixing post 34. The first fixing post 34 is provided on both sides of the fixing block 33. The fixing block 33 is fixedly installed on the top of the support base 1 by screws, and the connecting plate 32 rotates around the first fixing post 34.

[0029] Meanwhile, the support base 1, fixing ring 5, fixing base 2, pin 6, pin head 62, spring 61, and upper fixing mechanism 3 are all made of insulating materials.

[0030] In this embodiment, the surge arrester body 4 is inserted into the limiting hole 13 by passing through the fixing ring 5, and the ground wire is pulled out from the grounding hole 15. Since the limiting hole 13 has a positioning groove 14 at the bottom, the surge arrester body 4 can only be inserted into the limiting hole 13 at a fixed angle. During the insertion process, the surge arrester body 4 contacts the pin head 62 until it contacts the groove. Under the action of downward pressure, the pin head 62 squeezes the spring 61 and enters the locking cavity 9. Then, under the reset action of the spring 61, the pin head 62 is pushed into the groove opened in the surge arrester body 4, thereby locking the surge arrester body 4. Then, the connecting plate 32 is pushed to drive the semi-circular sleeve 31 to rotate around the first fixing post 34 as the central axis until it contacts the upper part of the surge arrester body 4. Then, the two semi-circular sleeves 31 are connected by screws and bolts until the surge arrester body 4 is squeezed and locked tightly.

[0031] Next, pull the fixing seat 2, and the fixing seat 2 will rotate around the second fixing column 7 as the central axis under the action of the connecting block 8, placing the power pole in the fixing seat 2, and then using screws and bolts to firmly lock the power pole in the fixing seat 2, thereby making the support seat 1 also tightly locked on the power pole.

[0032] Next, when it is necessary to remove the surge arrester body 4, simply loosen the screws and bolts to remove the surge arrester body 4 and the insulating base from the power pole. Then loosen the screws and bolts again to open the upper fixing mechanism 3. Then pull the pin 6, and the pin head 62 will be pulled out from the groove, thus unlocking the surge arrester body 4 and allowing it to be removed.

[0033] In this utility model, the surge arrester body 4 is inserted into the limiting hole 13 through the fixing ring 5, and the pin head 62 is inserted into the groove opened on the surge arrester body 4 to lock the surge arrester body 4. Then, the fixing mechanism 3 is used to fix the surge arrester body 4, so that the surge arrester body 4 is firmly installed in the insulating base, so that the surge arrester body 4 will not easily fall off the insulating base when facing strong winds.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
