[0026] Example 1:

[0027] Reference Figure 1 An electronic transformer that is easy to disassemble and assemble quickly includes a base plate 1, a housing 2, and a transformer assembly. The transformer assembly includes a magnetic core 3 and a winding coil 4 wound on the magnetic core 3. A connecting portion 6 is provided on the side of the base plate 1. The connecting portion 6 has a connecting hole. The connecting portion 6 is used to install and fix the base plate 1 to an external support structure. "L"-shaped brackets 5 are symmetrically provided at both ends of the magnetic core 3. The upper portion of the bracket 5 is connected and fixed to the magnetic core 3, and the lower portion of the bracket 5 extends laterally outward. The housing 2 covers the outside of the transformer assembly, and the lower portion of the housing 2 protrudes laterally outward to form an annular portion at the lower edge of the housing 2 (that is, the cross-sectional shape of the housing 2 is in the shape of a "J").

[0028] Reference Figure 2 The annular portion at the lower part of the shell 2 overlaps with the lower part of the bracket 5, and first through holes 7 are symmetrically opened at the four corners of the annular portion. A second through hole 8 is opened at the lower part of the bracket 5, and the second through hole 8 is coaxial with the first through hole 7. Positioning bolts 13 are passed through the first through hole 7 and the second through hole 8. Accommodation cavities 10 are opened on the bottom plate 1 corresponding to the lower parts of the four groups of positioning bolts 13, and the lower ends of the positioning bolts 13 extend into the accommodating cavities 10.

[0029] Reference Figure 2 and Figure 4 Two sets of transverse through-holes 11 are also provided in the base plate 1. Each set of through-holes 11 extends from left to right through the accommodating cavities 10 at the left and right ends of the base plate 1. The through-holes 11 are connected to the accommodating cavities 10. An operating rod 12 is provided in the through-holes 11 and passes through the accommodating cavities 10 at the left and right ends of the base plate 1. A locking groove 15 is provided on the lower side wall of the positioning bolt 13. A protruding locking block 21 is provided on the side of the operating rod 12. The locking groove 15 is used for receiving the locking block 21. When the operating rod 12 slides back and forth in the through-hole 11, the locking block 21 can enter or separate from the locking groove 15.

[0030] In this embodiment, the locking block 21 is subsequently fixed to the operating rod 12. That is, the operating rod 12 is first inserted into the insertion hole 11, and then the locking block 21 is fixed to the operating rod 12 in the accommodating cavity 10 by welding or other means. Since the locking block 21 can only move within the accommodating cavity 10, it can limit the displacement of the operating rod 12 and prevent the operating rod 12 from separating from the base plate 1.

[0031] Considering that when the operating rod 12 slides back and forth, the locking block 21 may collide with the side walls of the accommodating chamber 10 and produce noise, in this embodiment, a contact ring 17 is fixed to the rod body of the operating rod 12 located within the accommodating chamber 10. The contact ring 17 can be made of plastic or hard rubber to provide a buffer and silencer. When the operating rod 12 slides back and forth, the contact ring 17 can contact the side walls of the accommodating chamber 10 and the positioning bolt 13, acting as a limiter and isolation, preventing the locking block 21 from directly colliding with the side walls of the accommodating chamber 10 and preventing the occurrence of loud noise.

[0032] In this embodiment, one end of the operating rod 12 extends from the side of the base plate 1, and a handle 18 is provided on the side of the base plate 1. The handle 18 is connected and fixed to the ends of the two groups of operating rods 12. The two groups of operating rods 12 can be slid simultaneously by pushing and pulling the handle 18.

[0033] The installation process of the electronic transformer is as follows: the shell 2 is covered on the outside of the transformer assembly, the annular portion of the lower part of the shell 2 is aligned and overlapped with the lower part of the bracket 5, so that the first through hole 7 and the second through hole 8 are coaxial, and then the four groups of locking bolts are respectively passed through the first through holes 7 and the second through holes 8 of each group, so that the lower ends of the locking bolts enter the accommodating cavity 10; then, holding the handle 18, the two groups of operating rods 12 are respectively inserted into the two groups of insertion holes 11. When the operating rods 12 are inserted into place, the positioning blocks just enter the positioning grooves. At this time, the operating rods 12 lock the positioning bolts 13, so that the positioning bolts 13 cannot move upward, and the bolt heads of the positioning bolts 13 only press downward on the annular portion of the shell 2 and the lower part of the bracket 5, so that the base plate 1, the transformer assembly and the shell 2 are reliably combined into one.

[0034] In order to facilitate holding the handle 18 , in this embodiment, an annular recessed portion 22 is provided in the middle of the handle 18 along its circumference, and anti-slip pads 23 are fixed on the upper and lower surfaces of the recessed portion 22 .

[0035] In this embodiment, multiple sets of auxiliary positioning blocks 31 for contacting the bracket 5 and the shell 2 are fixed on the bottom plate 1 to facilitate more accurate installation of the positioning bolt 13 into the accommodating cavity 10 and to prevent the shell 2 from being displaced after assembly.

[0036] In this embodiment, a wire hole (not shown in the figure) is provided on the side wall of the housing 2 , and the end of the winding coil 4 passes through the wire hole so that the winding coil 4 can be connected to an external circuit.

[0037] The disassembly process of the electronic transformer is as follows: hold the handle 18 and pull out the two sets of operating rods 12 a certain distance so that the locking blocks 21 on the operating rods 12 are separated from the locking grooves 15 on the positioning bolts 13. At this time, all four sets of positioning bolts 13 are unlocked; then open the shell 2 upwards, and then the transformer assembly can be easily removed, thereby completing the disassembly of the entire electronic transformer.

[0038] The electronic transformer can lock the shell 2, the bracket 5 and the base plate 1 into one and disassemble them by pushing and pulling the operating lever 12, replacing the traditional method of disassembly and assembly by screwing. The operation is simpler, more convenient and efficient, which is conducive to improving the assembly efficiency of the electronic transformer and facilitating subsequent maintenance of the electronic transformer.

[0039] like Figure 4 As shown, the cross-sectional shapes of the operating rod 12 and the positioning bolt 13 in this embodiment are both rectangular, that is, the operating rod 12 and the positioning bolt 13 are both square structures; correspondingly, the second through hole 8 and the insertion hole 11 are also square holes. The square structure allows the positioning bolt 13 to limit the positioning bolt 13 when passing through the second through hole 8, preventing the positioning bolt 13 from rotating; similarly, when the operating rod 12 is inserted into the insertion hole 11, it can limit the operating rod 12 and prevent the operating rod 12 from rotating, thereby ensuring that the locking block 21 on the operating rod 12 always faces the locking groove 15 on the positioning bolt 13, ensuring that there is no misalignment and that the locking block 21 can enter the locking groove 15.

[0040] like Figure 2 As shown, in this embodiment, both ends of the locking groove 15 are trumpet-shaped. The trumpet-shaped structure has the function of guiding and assisting positioning, which can facilitate the locking block 21 to enter the locking groove 15 more easily and smoothly when pushing and pulling the operating rod 12.

[0041] In this embodiment, a third through hole 9 is further provided at the lower portion of the bracket 5, and the third through hole 9 is located directly above the second through hole 8. The sum of the depth of the third through hole 9 and the depth of the second through hole 8 is equal to the thickness of the lower portion of the bracket 5; the size of the third through hole 9 is larger than the size of the second through hole 8, and the size of the first through hole 7 is larger than the size of the second through hole 8; a booster spring 14 is sleeved on the positioning bolt 13, and the upper end of the booster spring 14 is connected and fixed to the bottom surface of the bolt head of the positioning bolt 13, and the lower end of the booster spring 14 is in contact with the bottom surface of the third through hole 9.

[0042] After adding the assist spring 14, during the assembly of the electronic transformer, the four groups of positioning bolts 13 are pressed downward to compress the assist spring 14, and then the operating rod 12 is pushed to make the locking block 21 enter the locking groove 15 to complete the locking; when disassembling, the operating rod 12 is pulled outward to separate the locking block 21 from the locking groove 15. At this time, the elastic force of the assist spring 14 will cause the positioning bolt 13 to automatically pop up, making it easy to remove the positioning bolt 13.

[0043] Reference Figure 1 and Figure 3 In this embodiment, a magnet block 19 is installed at the inner end of the insertion hole 11. The magnet block 19 is used to attract the end of the operating rod 12. When the operating rod 12 is inserted into the insertion hole 11, the magnet block 19 attracts the end of the operating rod 12, thereby providing additional attraction and stabilization for the operating rod 12, so that the operating rod 12 will not slide or loosen due to vibration or gravity.

[0044] In this embodiment, the magnet block 19 is bonded and fixed in the insertion hole 11 by the bonding block 20 .

[0045] Example 2:

[0046] Reference Figure 5 and Figure 6 Based on the first embodiment, this embodiment designs the housing 2 into a telescopic housing 2 structure. Specifically, the housing 2 in this embodiment includes an upper housing 201 and a lower housing 203. An upwardly concave annular active cavity 202 is provided along its circumference on the bottom end surface of the upper housing 201. The upper edge of the lower housing 203 enters the active cavity 202 and can slide freely within the active cavity 202. In this way, the lower housing 203 can move up and down relative to the upper housing 201, that is, the housing 2 can be telescoped in the vertical direction.

[0047] An auxiliary reset mechanism is also provided on the inner sidewall of the housing 2. The auxiliary reset mechanism includes a vertically arranged movable rod 24 and a sleeve 25. The lower end of the movable rod 24 extends into the sleeve 25, and the lower end of the movable rod 24 is provided with an outwardly protruding annular step 26. The movable rod 24 can be freely raised and lowered within the sleeve 25. The annular step 26 cooperates with the limit step 30 at the top of the sleeve 25 to prevent the movable rod 24 from separating from the sleeve 25. A rebound spring 27 is installed within the sleeve 25. The upper end of the rebound spring 27 abuts the bottom surface of the movable rod 24, and the lower end of the rebound spring 27 abuts the bottom of the sleeve 25. The rebound spring 27 is in a compressed state. The upper end of the movable rod 24 is connected and fixed to the inner wall of the upper housing 201 via a first connecting block 286, and the lower end of the sleeve 25 is connected and fixed to the inner wall of the lower housing 203 via a second connecting block 29. A squeeze block 16 is fixed to the outer wall of the upper housing 201 and is located directly above the positioning pin 13. When the upper housing 201 is not being pressed downward and the positioning pin 13 is being lifted by the assist spring 14, the squeeze block 16 just contacts the positioning pin 13; the downward stroke of the upper housing 201 is equal to the downward stroke of the positioning pin 13.

[0048] Since the positioning bolt 13 contacts the extrusion block 16 when it bounces up, the positioning bolt 13 can be prevented from being separated from the lower shell 203.

[0049] The assembly process of the electronic transformer in this embodiment is as follows: the transformer assembly is placed in the housing 2 and the position of the transformer assembly is finely adjusted so that the second through hole 8 at the lower part of the bracket 5 is aligned with the lower end of the positioning bolt 13; the lower end of the bracket 5 is then inserted into the positioning bolt 13, even if the lower end of the positioning bolt 13 passes through the second through hole 8, at which time the lower end of the assist spring 14 is tightly pressed against the bottom of the third through hole 9; then the lower end of the positioning bolt 13 is aligned with each accommodating cavity 10 with the help of the auxiliary positioning block 31; then the upper housing 20 is pressed down with force. 1. At this time, the upper shell 201 drives the extrusion block 16 to descend, and the extrusion block 16 pushes the positioning bolts 13 downward. When the upper shell 201 is pressed down into place, the positioning bolts 13 are also pushed into place by the extrusion block 16. Then, maintain the downward pressure on the upper shell 201, hold the handle 18 and push the operating rod 12 inward. When the operating rod 12 is pushed into place, the locking block 21 completely enters the locking groove 15, locking the four groups of positioning bolts 13. Then, remove the pressure on the upper shell 201, and the assembly of the electronic transformer is completed.

[0050] During disassembly, hold the handle 18 and pull the operating rod 12 outward for a distance, so that the locking block 21 on the operating rod 12 is separated from the locking groove 15 on the bolt, thereby unlocking the positioning bolt 13. At this time, the assist spring 14 bounces the positioning bolt 13 upward, and the rebound spring 27 drives the upper shell 201 to rise and reset. After that, the shell 2, transformer assembly and base plate 1 can be directly disassembled completely, which is very convenient.

[0051] In this embodiment, after the telescopic housing 2 and the extrusion block 16 are added, only two simple steps are required, namely, pressing down the upper housing 201 and pushing the operating rod 12, to complete the assembly of the electronic transformer, without the need to operate each positioning bolt 13 separately; the entire electronic transformer can be disassembled by simply pulling out the operating rod 12, which is simpler and more convenient.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
