DETAILED DESCRIPTION

[0040] The application provides a porcelain insulator glued with low-temperature adhesive, as shown in the figure. Figures 1-11 The application provides a porcelain insulator glued with low-temperature adhesive, as shown in the figure.

[0041] The bottom end of the cap body 3 is fixedly connected with the threaded rod 24, the threaded rod 24 is threadedly connected with the nut 25, in use, the threaded rod 24 is passed through the mounting hole on the cross arm or other power equipment from top to bottom, then the nut 25 is butt-jointed with the threaded rod 24, so that the porcelain insulator is installed and fixed.

[0042] The bottom end of the insulator body 1 is sleeved with the cap body 3, and the insulator body 1 and the cap body 3 are fixed in a way that the adhesive is filled, for example, low-temperature adhesive (including but not limited to epoxy resin low-temperature adhesive), so that the heating and curing process is omitted, the insulator body 1 and the cap body 3 are not easy to be loosened under cold and hot cycles and mechanical impact, and the service life is prolonged.

[0043] In order to avoid the inclination of the insulator body 1 and the cap 3 in the gluing process and reduce the quality of the porcelain insulator, a positioning assembly is arranged between the insulator body 1 and the cap 3, the positioning assembly comprises a limiting block 4, a longitudinal groove 5 and a limiting block 7, the limiting block 4 is fixedly connected to the inner wall of the cap 3, the longitudinal groove 5 is arranged on the limiting block 4, and the longitudinal groove 5 penetrates the top end of the limiting block 4 and the side of the limiting block 4 facing the axis of the cap 3 (referring to Figure 11 ), and the limiting block 7 is fixedly connected to the outer wall of the insulator body 1 and is inserted into the longitudinal groove 5.

[0044] The positioning assembly is provided with multiple groups, and the multiple groups of positioning assemblies are uniformly distributed around the axis of the cap 3.

[0045] In actual use, the opening of the cap 3 is vertically upward, an operator holds the insulator body 1 and moves it vertically downward, wherein the limiting block 7 is vertically aligned with the corresponding longitudinal groove 5, and as the insulator body 1 continues to move downward and is inserted into the cap 3, the limiting block 7 is inserted into the longitudinal groove 5, and due to the arrangement of multiple groups of positioning assemblies, the insulator body 1 and the cap 3 are quickly concentrically distributed and will not randomly shake; then the position between the insulator body 1 and the cap 3 is filled with adhesive, and after the adhesive is cured, the connection and fixation of the insulator body 1 and the cap 3 are completed.

[0046] By arranging the positioning assembly and other structures, the insulator body 1 and the cap 3 are quickly concentrically distributed and will not randomly shake, avoiding the inclination of the insulator body 1 and the cap 3 in the gluing process and improving the quality of the porcelain insulator.

[0047] In order to improve the strength of the connection between the insulator body 1 and the cap 3, the limiting block 7 comprises an upper block 701 and a lower block 702, and a gap is reserved between the upper block 701 and the lower block 702, a flow hole 6 is arranged on the side wall of the limiting block 4 and communicates with the longitudinal groove 5, and the shape of the flow hole 6 can be circular, triangular or the like, which can be adjusted according to specific use conditions.

[0048] When the limiting block 7 is inserted into the longitudinal groove 5, the upper surface of the upper block 701 is flush with the upper surface of the cap 3 and the limiting block 4, and the lower block 702 abuts against the bottom end of the longitudinal groove 5, at this time, there is a certain gap between the lower surface of the insulator body 1 and the bottom end inside the cap 3, which is used for the penetration of the adhesive, increases the filling area of the adhesive, and improves the strength of the connection.

[0049] Meanwhile, after the upper block 701 and the lower block 702 are inserted into the longitudinal groove 5, the gap between the upper block 701 and the lower block 702 corresponds to the flow hole 6 and communicates with the flow hole 6, the adhesive can penetrate into the longitudinal groove 5 through the flow hole 6, and the gap between the upper block 701 and the lower block 702 is filled, so that the adhesive and the positioning assembly form an integral whole.

[0050] Through the setting of the upper block 701, the lower block 702, the flow hole 6 and the like, the adhesive can seep into the longitudinal groove 5 from the flow hole 6, so that the adhesive and the positioning assembly form an integral whole, and the connection strength of the insulator body 1 and the cap body 3 is improved.

[0051] In order to ensure the stability of the filling of the adhesive, a glue layer 8 is arranged at the bottom end in the cap body 3, and the glue layer 8 is formed by quick-drying glue. Before the insulator body 1 is inserted into the cap body 3, an appropriate amount of quick-drying glue is applied at the bottom end in the cap body 3, so that after the insulator body 1 is inserted into the cap body 3, the two are quickly fixed together, preliminary fixation is achieved, the relative random movement between the insulator body 1 and the cap body 3 in the axial direction is prevented, and subsequent filling of the adhesive is facilitated. After the quick-drying glue is solidified, the glue layer 8 is formed.

[0052] Considering that the insulator body 1 and the cap body 3 are only fixed by the adhesive, the stability is generally poor after long-term use, and after the position between the insulator body 1 and the cap body 3 is filled with the adhesive, since the bottom end of the cap body 3 is fixedly connected with the threaded rod 24, the insulator body 1 and the cap body 3 are difficult to be placed vertically and also need to be placed vertically by the operator to wait for the adhesive to lose fluidity, and then to be placed obliquely or horizontally, which increases the working strength of the operator and affects the production efficiency of the porcelain insulator. In order to realize efficient fixation and improve the production efficiency, a ring groove 18 is reserved on the insulator body 1, the ring groove 18 is located between the umbrella skirt 2 at the lowermost position and the cap body 3, a ring sleeve 19 is fixedly connected in the ring groove 18, and the ring sleeve 19 is T-shaped in cross section, the protruding part is located in the ring groove 18, the upper and lower ends of the ring sleeve 19 are attached to the outer wall of the insulator body 1, and the ring sleeve 19 is fixed on the insulator body 1 by welding of two semicircular parts. Figure 8

[0053] The two sides of the cap body 3 are fixedly connected with the ear plates 9, the horizontal rods 10 are rotatably arranged on the ear plates 9, the two ends of the horizontal rods 10 are fixedly connected with the circular rods 14 through the elastic assemblies, the elastic assemblies include the first fixed blocks 11, the second fixed blocks 12 and the elastic telescopic rods 13, the first fixed blocks 11 are fixedly connected with the horizontal rods 10, the second fixed blocks 12 are fixedly connected with the circular rods 14, one end of the elastic telescopic rods 13 is fixedly connected with the first fixed blocks 11, and the other end of the elastic telescopic rods 13 is fixedly connected with the second fixed blocks 12.

[0054] The two sides of the cap body 3 are provided with the reinforcing assemblies, the reinforcing assemblies include the pressing plates 17 and the clamping ears 21, the pressing plates 17 are parallelly distributed with the horizontal rods 10 (refer to Figure 3 ), the two ends of the pressing plates 17 are slidably arranged on the corresponding two circular rods 14, so that the two circular rods 14 can be synchronously flipped, the clamping ears 21 are fixedly connected on the side of the pressing plates 17 facing the cap body 3, and the outer wall of the ring sleeve 19 is provided with the clamping holes 20 for inserting the clamping ears 21.

[0055] ​A locking assembly is provided between the two pressure plates 17. The locking assembly includes an active sleeve 15 and a passive sleeve 16. The active sleeve 15 is mounted on the corresponding round rod 14 and is rotatably connected to the corresponding pressure plate 17. When the active sleeve 15 slides on the round rod 14, it can drive the corresponding pressure plate 17 to slide synchronously. Since the active sleeve 15 and the corresponding pressure plate 17 are rotatably connected, the rotation of the active sleeve 15 is not affected. The passive sleeve 16 is mounted on the corresponding round rod 14 and is fixedly connected to the corresponding pressure plate 17. When the passive sleeve 16 slides on the round rod 14, it can drive the corresponding pressure plate 17 to slide synchronously.

[0056] The active sleeve 15 and the passive sleeve 16 are threaded together at their close ends. Specifically, the active sleeve 15 has an internal thread at the end close to the passive sleeve 16, and the passive sleeve 16 has an external thread at the end close to the active sleeve 15. The internal and external threads are engaged, and the friction coefficient between the internal and external threads is appropriate, so they will not rotate arbitrarily.

[0057] Furthermore, the locking component has two sets (see...). Figure 3 This ensures the stability of the overall structure.

[0058] The outer diameters of the active sleeve 15 and the passive sleeve 16 are the same, refer to... Figure 4 When the active sleeve 15 and the passive sleeve 16 are connected, the tops of the active sleeve 15, the passive sleeve 16, and the second fixed block 12 can be on the same horizontal plane.

[0059] Before gluing, rotate the reinforcing components, locking components, and other structures to position them below the cap body 3 (refer to...). Figure 6 Next, control the active sleeve 15 and passive sleeve 16 to move towards each other, causing the two pressure plates 17 to move towards each other. After the active sleeve 15 and passive sleeve 16 are aligned at their closest points, rotate the active sleeve 15 to connect and fix the active sleeve 15 and passive sleeve 16 together. This causes the crossbar 10, active sleeve 15, passive sleeve 16, second fixed block 12, and other structures to form a square support frame, with the bottoms of the active sleeve 15, passive sleeve 16, and second fixed block 12 on the same horizontal plane (see reference). Figure 6 To ensure stable contact with the ground, when the square support frame is placed on the operating table or other positions, it can provide vertical support for the insulator body 1 and cap 3, and can always maintain a vertical state without the assistance of operators, which facilitates the filling and curing of adhesive, and the connection and fixation of the insulator body 1 and cap 3.

[0060] By setting up reinforcement components, locking components and other structures, a square support frame is formed to vertically support the insulator body 1 and cap 3. It can always maintain a vertical state without the assistance of operators, which facilitates the filling and curing of adhesive and improves the production efficiency of porcelain insulators.

[0061] And the bottom end of the threaded rod 24 has a certain distance from the ground, and the elastic telescopic rod 13 is telescopic.

[0062] After filling the adhesive between the insulator body 1 and the cap 3, the operator holds the top end of the insulator body 1 and presses vertically downward, and the insulator body 1 and the cap 3 move downward synchronously, and the elastic telescopic rod 13 is contracted; then stop pressing, and under the action of the reset elastic force of the elastic telescopic rod 13, the insulator body 1 and the cap 3 move upward synchronously, and the operator's hand still controls the top end of the insulator body 1, and the vibration effect is generated by repeated operation for several times, so as to improve the filling compactness and mechanical properties of the adhesive.

[0063] By setting the elastic assembly and other structures, the vibration effect is generated, and the filling compactness and mechanical properties of the adhesive are improved.

[0064] After curing, the driving sleeve 15 is reversely rotated to separate the driving sleeve 15 and the driven sleeve 16, the reinforcing assembly and the locking assembly are rotated to be located above the cap 3 (refer to Figure 5 ), and the pressing plate 17 is stretched upward, the clamping ear 21 is aligned with the clamping hole 20, and the elastic telescopic rod 13 is completely stretched; then the driving sleeve 15 and the driven sleeve 16 are controlled to move towards each other, and the two pressing plates 17 are moved towards each other, and after the abutting ends of the driving sleeve 15 and the driven sleeve 16 are abutted, the driving sleeve 15 is rotated to connect and fix the driving sleeve 15 and the driven sleeve 16 together, the pressing plate 17 is attached to the outer wall of the ring sleeve 19, the clamping ear 21 is inserted into the corresponding clamping hole 20, and the horizontal rod 10, the driving sleeve 15, the driven sleeve 16 and the second fixed block 12 form a square reinforcing frame, the mechanical structure is used for reinforcing, and the elastic telescopic rod 13 is completely stretched, so that the connection between the insulator body 1 and the cap 3 is reinforced.

[0065] By setting the reinforcing assembly, the locking assembly and other structures, the square reinforcing frame is formed to reinforce the connection between the insulator body 1 and the cap 3, and the use strength of the porcelain insulator is improved.

[0066] The present application sets the reinforcing assembly, the locking assembly and other structures, and the gluing and fixing are combined with mechanical reinforcement to ensure the operation reliability of the porcelain insulator, and the support, vibration and reinforcement functions are flexibly switched to improve the use efficiency of the porcelain insulator.

[0067] And the abutting end of the driving sleeve 15 and the driven sleeve 16 can be provided with a latch and other structures to prevent the driving sleeve 15 from being randomly rotated, and can be adjusted according to specific use conditions.

[0068] The active sleeve 15 comprises, in sequence from the direction away from the passive sleeve 16, a butt joint section 1501, an adjusting section 1502 and a rotating section 1503, wherein the outer wall surface of the adjusting section 1502 is a regular hexagon, the internal thread is arranged at the inner wall of the butt joint section 1501, and the rotating section 1503 is rotationally connected with the pressing plate 17, and the outer wall surface of the adjusting section 1502 is a regular hexagon, so that the operator can use a wrench or the like to connect with the adjusting section 1502, thereby driving the rotation of the active sleeve 15.

[0069] The top end of the cap body 3 is attached with two symmetrical half-ring members 23, which can be assembled into a circular ring structure to attach the top end of the cap body 3 and surround the outside of the insulator body 1, and the half-ring members 23 are fixedly connected with connecting plates 22, and the ends of the connecting plates 22 away from the half-ring members 23 are fixedly connected with the corresponding pressing plates 17.

[0070] When the reinforcing assembly and the locking assembly are located above the cap body 3, and the active sleeve 15 is rotated to connect and fix the active sleeve 15 and the passive sleeve 16 together, the two half-ring members 23 abut against the top end of the cap body 3 and approach each other, and since the elastic extension rods 13 are in a fully stretched state at this time, the elastic extension rods 13 will not be retracted and contracted at will due to the limiting of the half-ring members 23, thereby reducing the working strength of the operator and facilitating the rapid butt joint and fixation of the active sleeve 15 and the passive sleeve 16.

[0071] The two half-ring members 23 are assembled into a circular ring structure to cover the top end of the cap body 3, so as to isolate the adhesive from the external environment, reduce the direct action of ultraviolet rays and rainwater, thereby delaying aging and prolonging the overall service life of the insulator.

[0072] The application further discloses a manufacturing method of the porcelain insulator glued by the low-temperature adhesive, which is applied to the manufacturing of the porcelain insulator glued by the low-temperature adhesive and comprises the following operation steps.

[0073] S1, gluing, inserting the insulator body 1 into the cap body 3 and performing anti-shaking treatment, and gluing by using the low-temperature adhesive;
