Description

Technical Field

[0001] This application belongs to the technical field of power facilities, and more specifically, relates to a quick-installation insulator structure. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware.

[0003] Currently, the connection structure between the top of the insulator and the conductor includes a lower cover and an upper cover. The lower cover is fixed to the top of the insulator, and the upper cover is fastened to the lower cover. The conductor is sandwiched between the lower cover and the upper cover. Bolts are vertically inserted through both sides of the lower cover and the upper cover. Nuts are connected to the bottom of the bolts. The upper cover and the lower cover are connected and fixed by two sets of bolts and nuts.

[0004] This connection method requires tightening two sets of bolts and nuts sequentially, resulting in low connection efficiency between the top of the insulator and the conductor. This is especially true when a large number of insulators need to be installed, leading to slower overall progress and impacting the construction period. Summary of the Invention

[0005] The purpose of this application is to provide a quick-installation insulator structure to solve the technical problem of low connection efficiency between the top of the insulator and the conductor in the prior art, especially when a large number of insulators need to be installed, resulting in slow overall progress and affecting the construction period.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a quick-installation insulator structure, including an insulator body, a lower cover fixed to the top of the insulator body, an upper cover fastened to the lower cover, and a groove for accommodating a conductor between the lower cover and the upper cover; the quick-installation insulator structure further includes: Two insert plates are vertically fixed on both sides of the top surface of the lower cover; slots for inserting the corresponding insert plates are provided on both sides of the bottom surface of the upper cover. Two sets of automatic fixing components are respectively disposed on the two insert plates; each slot has a slot on its inner side, and the automatic fixing component has a locking part for elastically inserting into the corresponding slot; and An unlocking mechanism is provided on the upper cover, which is used to simultaneously disengage the two latching parts from their corresponding slots. In one possible implementation, based on the above technical solutions, a fixing groove is provided on the inner side of the insert plate, and when the insert plate is inserted into the slot, the fixing groove communicates with the corresponding card slot; the automatic fixing component includes: A fixing spring is disposed within the corresponding fixing groove; A fixing block is slidably disposed at the opening of the fixing groove and is used to insert into the slot; When the fixing spring is in a free state, the fixing block is simultaneously located in the fixing groove and the card slot.

[0007] In one possible implementation, based on the above technical solutions, the top surface of the fixing block located within the slot is inclined downwards from the slot opening direction.

[0008] In one possible implementation, based on the above technical solutions, the upper cover has an unlocking slot communicating with the two card slots; the unlocking mechanism includes: A screw is vertically threaded to the top of the upper cover and located between the two slots, with the bottom of the screw located within the unlocking slot; A turntable, with an elliptical cross-section, is coaxially fixed to the bottom of the screw. When the turntable rotates, it simultaneously pushes the two fixing blocks out of the slot; and A positioning component is disposed on the upper cover for fixing the position of the screw.

[0009] In one possible implementation, based on the above technical solutions, the bottom edge of the turntable is set in the form of a cone, and the cross-sectional area of ​​the cone gradually decreases from top to bottom.

[0010] In one possible implementation, in conjunction with the above technical solutions, when the turntable pushes the two fixing blocks out of the slot, the outer peripheral surface of the turntable abuts against the side wall of the insert plate.

[0011] In one possible implementation, based on the above technical solutions, the positioning component includes: A positioning gear is coaxially fixed on the screw and located in the unlocking slot, with the positioning gear positioned above the turntable; The slider is horizontally slidable within the unlocking slot and faces the positioning gear; a strip-shaped hole is provided on the top of the upper cover, and the top of the slider protrudes from the strip-shaped hole; A positioning tooth is fixed to one end of the slider facing the positioning gear. The positioning tooth is used to mesh with the positioning gear, and the positioning tooth is always directly opposite the positioning gear. An elastic element is disposed within the unlocking groove and connected to the slider; when the elastic element is in a free state, the positioning teeth engage with the positioning gear.

[0012] In one possible implementation, based on the above technical solutions, the elastic element is a spring, with one end connected to the side wall of the unlocking groove and the other end connected to the slider.

[0013] In one possible implementation, based on the above technical solutions, a locking nut is threaded onto the screw, and the locking nut is used to press against the top surface of the upper cover.

[0014] In one possible implementation, based on the above technical solutions, there are two locking nuts, which are sequentially threaded onto the screw.

[0015] The advantages of the quick-installation insulator structure provided in this application are as follows: Compared with the prior art, in terms of installation, this application only requires the upper cover to be fastened onto the lower cover, allowing the insert plate to be inserted into the slot. The snap-fit ​​part of the automatic fixing component will then elastically insert into the slot, achieving a quick connection between the upper and lower covers. This avoids the tedious operation of sequentially tightening two sets of bolts and nuts, greatly improving the connection efficiency between the top of the insulator and the conductor. Especially when a large number of insulators need to be installed, it can effectively speed up the overall progress and avoid affecting the construction period. Attached Figure Description

In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0025] The quick-installation insulator structure provided in this application will now be described.

[0026] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a quick-installation insulator structure, including an insulator body 1, a lower cover 2 fixed to the top of the insulator body 1, an upper cover 3 fastened to the lower cover 2, and a groove for accommodating a conductor between the lower cover 2 and the upper cover 3; the quick-installation insulator structure also includes two insert plates 4, two sets of automatic fixing components 5 and a set of unlocking mechanisms 6.

[0027] Two insert plates 4 are vertically fixed on both sides of the top surface of the lower cover 2; slots 31 for inserting the corresponding insert plates 4 are provided on both sides of the bottom surface of the upper cover 3; two sets of automatic fixing components 5 are respectively set on the two insert plates 4; slots 32 are provided on the inner side of each slot 31, and the automatic fixing components 5 have a snap-fit ​​part for elastically inserting into the corresponding snap-fit ​​part 32; and an unlocking mechanism 6 is set on the upper cover 3, which is used to simultaneously drive the two snap-fit ​​parts to disengage from the corresponding snap-fit ​​parts 32.

[0028] The quick-installation insulator structure provided in this embodiment, compared with the prior art, offers several advantages in installation. Simply fasten the upper cover 3 onto the lower cover 2, insert the insert plate 4 into the slot 31, and the snap-fit ​​part of the automatic fixing component 5 will elastically insert into the slot 32, achieving a rapid connection between the upper cover 3 and the lower cover 2. This avoids the tedious operation of sequentially tightening two sets of bolts and nuts, greatly improving the connection efficiency between the top of the insulator and the conductor. Especially when installing a large number of insulators, it can effectively speed up the overall progress and avoid affecting the construction schedule.

[0029] In terms of disassembly, the unlocking mechanism 6 can simultaneously disengage the two locking parts from the corresponding slots 32, thereby facilitating the separation of the upper cover 3 from the lower cover 2. This makes it easier to inspect and replace the insulator, improving the maintenance efficiency of the insulator and reducing maintenance costs.

[0030] Furthermore, the cooperation between the insert plate 4 and the slot 31 not only serves a positioning function, ensuring the accurate installation of the upper cover 3 and the lower cover 2, but also enhances the stability of the structure, making the insulator more reliable during operation. The elastic snap-fit ​​method of the automatic fixing component 5 can accommodate a certain amount of installation error, ensuring the firmness of the connection.

[0031] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The inner side of the insert plate 4 is provided with a fixing groove 41. When the insert plate 4 is inserted into the slot 31, the fixing groove 41 is connected to the corresponding card slot 32. The automatic fixing component 5 includes a fixing spring 51 and a fixing block 52. The fixing spring 51 is disposed in the corresponding fixing groove 41. The fixing block 52 is slidably disposed at the opening of the fixing groove 41 and is used to insert into the card slot 32. When the fixing spring 51 is in a free state, the fixing block 52 is simultaneously located in the fixing groove 41 and the card slot 32.

[0032] The fixing spring 51 provides elastic force to the fixing block 52, enabling the fixing block 52 to automatically insert into the slot 32 when the insert plate 4 is inserted into the slot 31, thus achieving an automatic fixing function. When the insert plate 4 is inserted into the slot 31, the fixing block 52 will automatically pop out and insert into the slot 32 under the action of the fixing spring 51, without the need for additional operation, further improving the convenience of installation.

[0033] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The top surface of the fixing block 52 located in the slot 32 is inclined downwards from the opening direction of the slot 32.

[0034] During the insertion of the insert plate 4 into the slot 31, the downward-sloping top surface acts as a guide, making it easier for the fixing block 52 to be inserted into the slot 32. When the insert plate 4 is inserted, the inclined top surface of the fixing block 52 will contact the edge of the slot 32. Under the action of the insertion force, the fixing block 52 will automatically slide into the slot 32 along the inclined surface, reducing the resistance during insertion and improving the smoothness of installation.

[0035] like Figure 2 and Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The upper cover 3 has an unlocking groove 33 inside that connects to the two slots 32; the unlocking mechanism 6 includes a screw 61, a turntable 62 and a positioning component 63; the screw 61 is vertically threaded to the top of the upper cover 3 and is located between the two slots 32, and the bottom of the screw 61 is located inside the unlocking groove 33.

[0036] The turntable 62 has an elliptical cross-section and is coaxially fixed to the bottom of the screw 61. When the turntable 62 rotates, it simultaneously pushes the two fixing blocks 52 out of the slot 32. The positioning component 63 is set on the upper cover 3 and is used to fix the position of the screw 61.

[0037] Rotating the screw 61 drives the turntable 62, which is coaxially fixed to the bottom of the screw 61, to rotate. Since the cross-section of the turntable 62 is elliptical, during rotation, the turntable 62 can simultaneously push the two fixing blocks 52 out of the slot 32, realizing the function of simultaneously unlocking the two automatic fixing components 5. This makes the unlocking operation more convenient and faster, and can be completed simply by rotating the screw 61, thus improving the disassembly efficiency.

[0038] The positioning component 63 is used to fix the position of the screw 61, ensuring that the screw 61 will not rotate arbitrarily after unlocking. This ensures that the fixing block 52 can be stably kept in the disengaged state from the slot 32, facilitating the separation of the upper cover 3 and the lower cover 2. At the same time, the positioning component 63 also prevents the screw 61 from rotating due to vibration or other reasons during the operation of the insulator, which could lead to the accidental unlocking of the automatic fixing component 5, thus improving the safety and reliability of the structure.

[0039] like Figure 2 and Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottom edge of turntable 62 is set in a conical shape, and the cross-sectional area of ​​the conical surface gradually decreases from top to bottom.

[0040] During the process of the screw 61 driving the turntable 62 to rotate downwards and push the fixing block 52 out of the slot 32, the conical surface of the bottom edge of the turntable 62 can squeeze the inclined surface of the fixing block 52. The two mutually compatible inclined surfaces can reduce friction and reduce the force required to rotate the screw 61, making the unlocking operation easier.

[0041] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: When the turntable 62 pushes the two fixing blocks 52 out of the slot 32, the outer peripheral surface of the turntable 62 presses against the side wall of the insert plate 4.

[0042] When disassembling by rotating screw 61, simply press the turntable 62 against the insert plate 4 to disengage the fixing block 52 from the slot 32. This achieves the effect of limiting the rotation of the turntable 62, preventing the turntable 62 from rotating excessively and entering the fixing slot 41, ensuring the smoothness of the insert plate 4 disengaging from the slot 31, and further improving the ease of operation.

[0043] like Figure 2 and Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning component 63 includes a positioning gear 631, a slider 632, a positioning tooth 633, and an elastic element 634; the positioning gear 631 is coaxially fixed on the screw 61 and located in the unlocking groove 33, and the positioning gear 631 is located above the turntable 62; the slider 632 is laterally slidably disposed in the unlocking groove 33 and faces the positioning gear 631; a strip-shaped hole is opened on the top of the upper cover 3, and the top of the slider 632 protrudes from the strip-shaped hole.

[0044] The positioning tooth 633 is fixed to the end of the slider 632 facing the positioning gear 631. The positioning tooth 633 is used to mesh with the positioning gear 631, and the positioning tooth 633 is always facing the positioning gear 631. The elastic element 634 is disposed in the unlocking groove 33 and connected to the slider 632. When the elastic element 634 is in the free state, the positioning tooth 633 meshes with the positioning gear 631.

[0045] When the elastic element 634 is in a free state, the positioning teeth 633 mesh with the positioning gear 631, which can effectively fix the position of the screw 61 and prevent the screw 61 from rotating due to vibration or other reasons during the operation of the insulator. This ensures the connection stability of the automatic fixing component 5 and realizes the automatic fixing of the screw 61 after rotation when the screw 61 is unlocked. This ensures the position stability of the fixing block 52 when the insert plate 4 is disengaged from the slot 31, thereby improving the ease of separation between the upper cover 3 and the lower cover 2.

[0046] By pushing the slider 632, the positioning teeth 633 can disengage from the positioning gear 631, thereby releasing the positioning of the screw 61 and facilitating the unlocking operation by rotating the screw 61. The positioning teeth 633 are always aligned with the positioning gear 631, ensuring that the positioning teeth 633 accurately engage with the positioning gear 631 after the screw 61 drives the turntable 62 to spiral upwards and downwards, thus improving the reliability of the positioning assembly 63.

[0047] like Figure 2 and Figure 4 As shown, the elastic element 634 is a spring, with one end connected to the side wall of the unlocking groove 33 and the other end connected to the slider 632.

[0048] The spring has good elastic properties, providing a stable elastic force to the slider 632 and ensuring that the positioning teeth 633 can reliably mesh with the positioning gear 631. The spring constant can be selected according to actual needs to meet different positioning requirements.

[0049] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A locking nut 611 is threaded onto the screw 61, and the locking nut 611 is used to press against the top surface of the upper cover 3.

[0050] After the screw 61 has rotated upwards or downwards, by keeping the screw 61 stationary and tightening the locking nut 611 onto the screw 61, the screw 61 can be fixed, preventing it from rotating due to vibration or other factors, thereby ensuring the secure connection of the automatic fixing assembly 5. Furthermore, there are two locking nuts 611, which are threaded onto the screw 61 in sequence.

[0051] The two locking nuts 611 provide double security, further enhancing the fixing effect of the screw 61. By tightening the two locking nuts 611 in sequence, the connection between the screw 61 and the upper cover 3 can be made more secure, effectively preventing the screw 61 from loosening.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application.
