Outdoor fully insulated voltage transformers are power equipment suitable for outdoor environments. Due to their excellent environmental adaptability and safety performance, they have become an indispensable component in outdoor power facilities.

[0003] In the prior art, according to patent application number: CN202120678161.1, a voltage transformer is provided, which covers the wiring terminals through two movable covers, so as to solve the problem that the wiring terminals are in contact with the external environment and are prone to rust, and the transformer is lifted by a movable pull rod, so as to facilitate the transportation of the transformer. However, during the transportation process, since the positions of the two covers are not restricted and there are threading holes formed on the covers, the wiring terminals are exposed to the outside, which makes the wiring terminals easily affected by the external environment, which is not conducive to the safe transportation of the voltage transformer.

[0004] Based on the above-mentioned defects, an outdoor fully insulated voltage transformer is provided. Utility Model Content

[0013] 1. In the present application, the two sliding arms are pulled outward by the handle, and the two sliding plates are opened in opposite directions synchronously until the block abuts against the inner wall of the docking groove. The handle is in a position away from the main body, which is convenient for the user to pull the main body by the handle.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: an outdoor fully insulated voltage transformer, comprising a body 1, a mounting base 15 fixed at the bottom of the body 1, and a terminal 2 mounted on the body 1, a retaining frame 3 is fixedly provided on one side of the terminal 2 of the body 1, two sliding plates 5 are slidably provided on the inner side of the retaining frame 3, a butt joint groove 6 corresponding to the terminal 2 is formed in the sliding plate 5, a retaining block 4 is fixedly provided on the outer end of the retaining frame 3, two sliding arms 10 are slidably connected to the outer side of the body 1, a transmission member is provided on the outer side of the body 1, and the sliding arm 10 drives the sliding plate 5 to slide along the retaining frame 3 through the transmission member when sliding. A handle 14 is fixedly provided between the two sliding arms 10.

[0023] When the voltage transformer needs to be transported, the two sliding arms 10 are pulled outward by the handle 14, so that the two sliding plates 5 are synchronously opened in opposite directions under the action of the transmission member. During this process, the block 4 will slide along the docking groove 6 until the block 4 abuts against the inner wall of the docking groove 6. The handle 14 is in a position away from the main body 1, which is convenient for the user to pull the main body 1 through the handle 14. The block 4 blocks the docking groove 6, so that during the transportation process, the terminal 2 is isolated from the external environment under the joint action of the sliding plate 5, the baffle frame 3 and the baffle 4, thereby achieving safe transportation of the voltage transformer.

[0024] When the body 1 is in the installed state, the handle 14 is in a position close to the body 1. At this time, the two sliding plates 5 are in a close state, and the docking groove 6 is not restricted by the block 4, so the terminal 2 is exposed outward to facilitate the docking of the wires. The entire movable structure is in a folded state, which is beneficial to reduce the space occupied, thereby facilitating the assembly of the voltage transformer.

[0025] Specifically, Figure 1 and Figure 3 As shown, the stopper 4 is slidably embedded in the docking groove 6, and the stopper 4 is formed with an arc surface adapted to the docking groove 6. When the sliding plate 5 slides and fits with the arc surface of the stopper 4, the opening of the wiring terminal 2 is closed. The docking groove 6 is formed with an arc structure for matching the wiring penetration, and the arc surface of the stopper 4 is adapted to the arc structure. When the sliding of the docking groove 6 is restricted by the stopper 4, the sliding plate 5, the stopper frame 3 and the stopper 4 together form a closed environment, which is beneficial to the protection of the wiring terminal 2.

[0026] Specifically, Figure 1-Figure 4 As shown, the transmission member includes a transverse shaft 8 fixed to the side end of the sliding plate 5 through a bracket 7, a frame plate 9 is fixed on the body 1 to cooperate with the transverse shaft 8 to slide through, and a traction member is arranged on the outer side of the stopper 4 to drive the transverse shaft 8 to slide through the frame plate 9.

[0027] The traction member drives the transverse axis 8 to slide along the frame plate 9 . During this process, the bracket 7 fixed to the transverse axis 8 drives the sliding plate 5 to move synchronously.

[0028] The traction member includes a first arm 11 rotatably connected to the outside of the frame plate 9, a second arm 12 rotatably connected between the first arm 11 and the sliding arm 10, a protrusion 13 is formed on the inner wall of the second arm 12, and a slide rail 801 is formed on the side wall of the horizontal axis 8 to slide with the protrusion 13, and the slide rail 801 has a spiral structure.

[0029] When the slide arm 10 slides along the main body 1, the first arm rod 11 rotatably connected to the slide arm 10 will pull the second arm rod 12 to rotate. During this process, the protrusion 13 fixed on the inner wall of the second arm rod 12 will slide along the slide rail 801. The protrusion 13 compresses the inner wall of the spiral slide rail 801, driving the horizontal axis 8 to drive the sliding plate 5 fixed to the bracket 7 to move.

[0030] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
