DETAILED DESCRIPTION

[0031] 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 in 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.

[0032] The utility model provides: a voltage transformer which is easy to assemble and install, such as Figure 1-Figure 8 As shown, it includes a positioning plate 1, and several groups of mounting seats 3 are equidistantly installed inside the positioning plate 1. Four groups of buffer rods 5 are symmetrically installed on the upper surface of the mounting seats 3. A group of trays 18 are commonly installed on the top of each group of buffer rods 5, and two groups of pull ropes 21 are symmetrically installed on the upper surface of the tray 18; two groups of L-shaped brackets 7 are movably installed on the bottom of the positioning plate 1; a protection plate 12 is fitted on the top of the positioning plate 1, and several groups of placement windows 13 are opened on the protection plate 12 corresponding to the positions of each group of storage slots 2, and two groups of limit windows 14 are symmetrically opened on both sides of each group of placement windows 13, and a group of pressure plates 22 are rotatably installed inside each group of limit windows 14, and an adjustment plate 25 is fixedly installed on the outer end of each group of pressure plates 22, and the end of the pull rope 21 is fixedly connected to the adjustment plate 25; a group of voltage transformer bodies 27 are placed inside each group of storage slots 2.

[0033] Preferably, a plurality of groups of storage grooves 2 are provided through the center of the positioning plate 1, and each group of mounting seats 3 is fixedly installed in contact with the inner wall of the storage groove 2, and a docking conductive disk 4 is fixedly installed at the top center of each group of mounting seats 3. The storage groove 2 provided in the center of the positioning plate 1 is used to ensure that each group of voltage transformer bodies 27 will not contact each other when placed for connection, and will not have any influence during the placement process, and the mounting seats 3 installed inside the storage grooves 2 are used to limit the docking conductive disk 4, so that when the tray 18 is pressed downward by force, the docking conductive plug rod 19 at the bottom of the tray 18 can be stably plugged with the docking conductive disk 4 to achieve the purpose of docking the two ends of the voltage transformer body 27, and the buffer rod 5 installed on the upper surface of the mounting seat 3 can buffer the movement of the tray 18 after the voltage transformer body 27 is placed in the storage groove 2, and can also reset the tray 18 when the tray 18 is taken out, thereby completing the power-off work, greatly improving the convenience and safety of later use.

[0034] Furthermore, four groups of slide grooves 6 are symmetrically opened in pairs at the bottom of each group of positioning plates 1, and two groups of inner sliding blocks 8 are symmetrically installed on the upper surface of each group of L-shaped brackets 7. Each group of inner sliding blocks 8 is slidably installed inside the slide groove 6. The slide groove 6 opened at the bottom of the positioning plate 1 cooperates with the inner sliding block 8 at the top of the L-shaped bracket 7 to complete the limitation of the L-shaped bracket 7. At the same time, the inner sliding block 8 can slide inside the slide groove 6 to select the specific use position of the L-shaped bracket 7, thereby better ensuring the overall installation and use of the device.

[0035] Furthermore, a limiting hole 9 is formed through the center of each group of inner sliding blocks 8, a connecting bolt 10 is inserted inside the inner sliding block 8, the L-shaped bracket 7 and the positioning plate 1 are locked and fixed by the connecting bolt 10, and two groups of locking holes 11 are symmetrically formed on the side of the L-shaped bracket 7. The limiting hole 9 formed in the center of the inner sliding block 8 allows the bolt head to be embedded in the inner sliding block 8, and the screw rod can extend from the inner sliding block 8 to the lower side of the L-shaped bracket 7. After the L-shaped bracket 7 needs to select the installation position, the inner sliding block 8 is pulled by rotating the nut, so that the inner sliding block 8 is subjected to force on the slide groove 6, thereby completing the positioning of the L-shaped bracket 7.

[0036] It is worth mentioning that four groups of right-angle motors 15 are symmetrically installed in pairs on both sides of the protection plate 12 corresponding to each group of placement windows 13. A group of internal threaded tubes 16 are rotatably installed at the output end of each group of right-angle motors 15. A group of positioning screws 17 are installed on the internal threads of each group of internal threaded tubes 16. Each group of right-angle motors 15 installed on both sides of the protection plate 12 is used to control the positioning screws 17 to extend from the inside of the protection plate 12 and insert into the locking holes 26 opened on both sides of the adjustment plate 25 to ensure the stability of the pressure plate 22 and the adjustment plate 25, and avoid the detachment of the voltage transformer body 27 during the use of the device.

[0037] Specifically, a through hole should be opened inside the protection plate 12 at the position of each group of internal threaded tubes 16, and a threaded groove should be opened inside each group of through holes at the position corresponding to the positioning screw 17. The positioning screw 17 is threadedly connected to the internal threaded groove of the through hole, and the positioning screw 17 can extend from the inside of the protection plate 12 into the inside of the placement window 13. The right-angle motor 15 controls the rotation of the internal threaded tube 16, and the internal threaded tube 16 drives the positioning screw 17 to rotate. Since the positioning screw 17 is cooperatively connected with the internal threaded groove of the through hole, the positioning screw 17 is subjected to force during rotation, so that the positioning screw 17 can be rotated outward, thereby completing the purpose of limiting the adjustment plate 25.

[0038] In addition, a docking conductive plug rod 19 is fixedly installed at the bottom of the tray 18, and the docking conductive plug rod 19 is installed in conjunction with the docking conductive disk 4. Four groups of limit rods 20 are symmetrically installed on the left and right sides of the top of the tray 18. The docking conductive plug rods 19 installed at the bottom of the tray 18 are plugged into the docking conductive disk 4. Each group of docking conductive plug rods 19 is connected to each other, so that each group of installed voltage transformer bodies 27 can be used in series. The limit rod 20 installed at the top of the tray 18 can cooperate with the L-shaped mounting frame 29, thereby ensuring the stability of the installation of the voltage transformer body 27.

[0039] It is worth mentioning that preferably, the pressure plate 22 rotates inside the placement window 13 and the limit window 14, the shafts at both ends of the pressure plate 22 rotate and insert into the protection plate 12, and force springs 23 are sleeved on the outside of the shafts at both ends of the pressure plate 22, and positioning holes 24 are opened on one side of the pressure plate 22 corresponding to each group of limit rods 20. The pressure plate 22 is located inside the limit window 14 as the starting position, and the force springs 23 at both ends of the shaft of the pressure plate 22 can apply pressure to the pressure plate 22 when the pressure plate 22 rotates, so that the pressure plate 22 can be quickly reset. Therefore, after the voltage transformer body 27 is placed on the upper part of the tray 18, it presses the tray 18 to make the tray 18 descend, and the pull rope 21 is ensured to pull the adjustment plate 25, so that the pressure plate 22 can be better rotated to the inside of the placement window 13 to dock with the limit rod 20.

[0040] Furthermore, two groups of side baffles 28 are symmetrically bolted on the front and rear sides of the voltage transformer body 27, and two groups of L-shaped mounting frames 29 are symmetrically bolted on the left and right sides of the voltage transformer body 27. A protective groove 30 is opened in the middle of the L-shaped mounting frame 29. The side baffles 28 installed on both sides of the voltage transformer body 27 can limit the voltage transformer body 27, and the L-shaped mounting frame 29 is used to cooperate with the tray 18 to complete the connection of each group.

[0041] Preferably, the voltage transformer body 27 is placed inside the storage slot 2 and then installed in fit with the tray 18. Each set of limit rods 20 is correspondingly inserted into the L-shaped mounting frame 29. After the pressure plate 22 is rotated, the positioning hole 24 is movably engaged with the limit rod 20. The protective groove 30 opened in the middle of the L-shaped mounting frame 29 can limit the pull rope 21, reduce the impact on the pull rope 21 during the lifting and lowering of the tray 18, and enable the pull rope 21 to stably pull the side adjustment plate 25 to complete the limiting of the adjustment plate 25.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
