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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-3 As shown:
[0024] A transformer with a lead-out mechanism includes a transformer body 101. Several sets of high-voltage output terminals 102 and low-voltage output terminals 103 are fixedly fixed on the top of the transformer body 101. A lead wire 104 is fixedly installed at one end of the low-voltage output terminal 103. A sunshade 105 is fixedly installed on the top of the transformer body 101.
[0025] The lead wire 104 is provided with a first hemisphere 106 and a second hemisphere 107. Multiple sets of first bolts 108 are installed between the first hemisphere 106 and the second hemisphere 107. The first hemisphere 106 and the second hemisphere 107 can be formed into a sphere. The first hemisphere 106 is provided with a through hole adapted to the first bolt 108. The second hemisphere 107 is provided with a threaded hole adapted to the first bolt 108. One end of the first bolt 108 passes through the through hole of the first hemisphere 106 and is threadedly connected to the threaded hole of the second hemisphere 107 for connection and locking of the first hemisphere 106 and the second hemisphere 107.
[0026] A symmetrically arranged connecting plate 110 is provided on the sunshade 105 near the lead wire 104;
[0027] An arc-shaped ball sleeve 109 is fixed at the bottom of the connecting plate 110. The two sets of arc-shaped ball sleeves 109 form an annular sleeve, and the outer diameter of the ball is larger than the inner diameter of the annular sleeve. An abutment plate 117 is fixed on the side of the two sets of connecting plates 110 that are far apart from each other. A limiting hole is opened on the sunshade 105 to insert into the two sets of connecting plates 110 that fit together. A crossbeam frame plate 111 is fixed on the upper surface of the sunshade 105. A second bolt 112 is installed between the connecting plate 110 and the crossbeam frame plate 111. A threaded groove 119 that matches the second bolt 112 is opened on one side of the connecting plate 110. One end of the second bolt 112 passes through the frame of the crossbeam frame plate 111 and is screwed into the threaded groove 119 opened in the connecting plate 110 for connection locking of the connecting plate 110 and the crossbeam frame plate 111.
[0028] Silicone pads 118 are fixed to the arc-shaped surfaces of the first hemisphere 106 and the second hemisphere 107 that are close to each other.
[0029] In this embodiment: When using the transformer with lead-out mechanism of the present invention, the first hemisphere 106 and the second hemisphere 107 are first installed on the surface of the lead wire 104, and the first hemisphere 106 and the second hemisphere 107 are tightly fixed to the lead wire 104 by the first bolt 108. The function of the first bolt 108 is to drive the first hemisphere 106 and the second hemisphere 107 to press against each other, generating sufficient pressing friction force, thereby firmly fixing them to the surface of the lead wire 104.
[0030] To enhance the fixing effect, silicone pads 118 are provided on the sides of the first hemisphere 106 and the second hemisphere 107 that are close to each other. The silicone pads 118 not only increase the squeezing friction of the first hemisphere 106 and the second hemisphere 107 on the lead wire 104 and improve the fixing effect, but also reduce the squeezing deformation of the lead wire 104 by the first hemisphere 106 and the second hemisphere 107 due to the buffering effect of the silicone pads 118.
[0031] One end of the lead wire 104 is fixed to the low-voltage output terminal 103. Next, the two sets of connecting plates 110 are attached together, and the two sets of arc-shaped ball sleeves 109 are attached to each other to form an annular sleeve, which is placed on the outside of the lead wire 104. Then, the two attached sets of connecting plates 110 are inserted together into the limiting hole opened in the sunshade 105. At this time, one side of the contact plate 117 is attached to the surface of the sunshade 105. The contact plate 117 plays a limiting role in the insertion of the connecting plate 110. At this time, the top of the connecting plate 110 extends to the top of the sunshade 105. Then, one end of the second bolt 112 is passed through the frame of the crossbeam frame plate 111 and screwed into the threaded groove 119 opened in the connecting plate 110, thereby realizing the connection and locking of the connecting plate 110 and the crossbeam frame plate 111.
[0032] The two sets of arc-shaped ball sleeves 109 form an annular sleeve, and the outer diameter of the sphere formed by the first hemisphere 106 and the second hemisphere 107 is larger than the inner diameter of the annular sleeve. When the worker pulls the lead wire 104, the first hemisphere 106 and the second hemisphere 107 will move synchronously, and the sphere will move closer to the two sets of arc-shaped ball sleeves 109. Since the inner diameter of the annular sleeve formed by the two sets of arc-shaped ball sleeves 109 is smaller than the outer diameter of the sphere, it can effectively block the sphere and will not interfere with the connection between the lead wire 104 and the low-voltage output terminal 103.
[0033] When the staff pulls the lead wire 104, the cooperation of the first hemisphere 106, the second hemisphere 107 and the arc-shaped ball sleeve 109 can effectively limit the lead wire 104, preventing the connection from becoming loose or falling off due to accidental dragging. This design ensures the reliability of the transformer connection, avoids transformer failure, and ensures that the transformer can maintain efficient operation during power conversion and transmission.
[0034] The balls provided on the arc-shaped ball sleeve 109 help reduce contact friction with the arc-shaped ball sleeve 109 when the lead wire 104 swings within the annular sleeve.
[0035] It should be noted that when the high-voltage output terminal 102 is equipped with a lead wire 104, the mechanism of this solution can also be used to prevent pulling when the high-voltage output terminal 102 is equipped with a lead wire 104.
[0036] Furthermore;
[0037] In an optional embodiment, a first arc-shaped piece 113 is fixed to the outer surface of the arc-shaped ball sleeve 109, a second arc-shaped piece 116 is provided on one side of the arc-shaped ball sleeve 109, and a plurality of sliding rods 114 are fixed to one side of the second arc-shaped piece 116. A spring 115 is wound around the surface of the sliding rod 114, and the two ends of the spring 115 are fixedly connected to the second arc-shaped piece 116 and the first arc-shaped piece 113 respectively. A moving hole adapted to the sliding rod 114 is opened on the first arc-shaped piece 113, and the sliding rod 114 can slide in the moving hole opened in the first arc-shaped piece 113.
[0038] The two sets of second arc-shaped pieces 116 are attached together to form a ring, and the inner diameter of the ring is smaller than the diameter of the sphere formed by the first hemisphere 106 and the second hemisphere 107.
[0039] In this embodiment: when the ball approaches the annular sleeve, it compresses the two sets of second arc-shaped plates 116. At the same time, the second arc-shaped plates 116 drive the slide rod 114 to slide on the first arc-shaped plate 113 and compress the spring 115. The spring 115 plays a buffering role, which reduces the impact between the ball and the arc-shaped ball sleeve 109 and further ensures the stability of the connection between the ball and the lead wire 104.
[0040] The working principle and usage process of this utility model are as follows: When using the transformer with lead-out mechanism of this invention, firstly, the first hemisphere 106 and the second hemisphere 107 are installed on the surface of the lead wire 104. The first hemisphere 106 and the second hemisphere 107 are tightly fixed to the lead wire 104 by the first bolt 108. The function of the first bolt 108 is to drive the first hemisphere 106 and the second hemisphere 107 to press against each other, generating sufficient pressing friction force, thereby firmly fixing them to the surface of the lead wire 104. One end of the lead wire 104 is fixed to the low-voltage output end 103. Next, the two sets of connecting plates 110 are attached together, and the two sets of arc-shaped ball sleeves 109 are attached together to form an annular sleeve, which is fitted over the outside of the lead wire 104. Then, the two attached sets of connecting plates 110 are inserted together into the limiting hole opened in the sunshade 105. At this time, one side of the contact plate 117 is attached to the surface of the sunshade 105, and the contact plate 117 is attached to the surface of the sunshade 105. The contact plate 117 limits the insertion of the connecting plate 110. At this time, the top of the connecting plate 110 extends to the top of the sunshade 105. Then, one end of the second bolt 112 passes through the frame of the crossbeam frame plate 111 and is screwed into the threaded groove 119 of the connecting plate 110, thereby locking the connection between the connecting plate 110 and the crossbeam frame plate 111. The two sets of arc-shaped ball sleeves 109 form an annular sleeve, and the outer diameter of the sphere formed by the first hemisphere 106 and the second hemisphere 107 is larger than the inner diameter of the annular sleeve. When the worker pulls the lead wire 104, the first hemisphere 106 and the second hemisphere 107 will move synchronously, and the sphere will move closer to the two sets of arc-shaped ball sleeves 109. Since the inner diameter of the annular sleeve formed by the two sets of arc-shaped ball sleeves 109 is smaller than the outer diameter of the sphere, it can effectively block the sphere and will not interfere with the connection between the lead wire 104 and the low-voltage output terminal 103.
