[0002] Small household transformers are usually used in household electrical appliances, such as televisions, stereos, lamps, etc., to convert the power voltage into the working voltage required by the equipment. In order to facilitate users to replace or repair equipment, designing an installation structure that is easy to disassemble and assemble quickly is a common design choice.

[0003] The installation structure for small household transformers that is easy to disassemble and assemble quickly is mainly intended to improve user experience, save space, reduce costs, improve production efficiency and meet market demand.

[0004] At present, the installation structure of small household transformers that are easy to disassemble and assemble quickly is mostly fixed with screws and nuts. Both disassembly and assembly require the help of additional disassembly tools, which is troublesome. Secondly, the size of the mounting seat is fixed, and only small transformers of fixed size specifications can be installed, and the scope of application is limited. Therefore, an installation structure for small household transformers that is easy to disassemble and assemble quickly is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an installation structure for a small household appliance transformer that is easy to disassemble and assemble quickly, aiming to improve the problem in the prior art that disassembly and assembly requires the aid of additional disassembly tools and can only install transformers of fixed sizes.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mounting structure for a small household transformer that is easy to disassemble and assemble quickly, comprising a mounting seat, the inner wall of the mounting seat is slidably connected to two groups of telescopic plates, the outer wall of the telescopic plate is detachably connected to the mounting plate, the transformer body is fixedly connected with an interval between the two groups of mounting plates, the outer wall of the telescopic plate is fixedly connected to a columnar block, the inner wall of the columnar block is slidably connected to a pull rod, the inner wall of the pull rod is slidably connected to two groups of card blocks, and the interval between the two groups of card blocks is elastically connected by a reset spring.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the mounting seat is rotatably connected with a threaded rod, the outer end of the threaded rod is fixedly connected with a knob, the outer wall of the threaded rod is threadedly connected with two groups of threaded sleeves, and the outer wall of the threaded sleeve is hinged with a bracket.

[0012] The two ends of the return spring are respectively fixedly connected to the inner ends of the two groups of clamping blocks.

[0013] As a further description of the above technical solution:

[0014] One inner end of the clamping block is clamped with the outer wall of the mounting plate.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the columnar block is in contact with the side wall of the card block.

[0017] As a further description of the above technical solution:

[0018] The end of the bracket is hinged with the inner side wall of the telescopic plate.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, by setting a card block and a pull rod, when installing the transformer, the circular groove of the mounting plate is aligned with the cylindrical block and directly inserted. When it needs to be removed, the card block is pressed inward and the pull rod is pulled upward to make the card block stuck in the cylindrical block. At this time, the transformer can be removed, and disassembly and assembly are relatively easy without the need for additional disassembly tools.

[0021] 2. In the utility model, by setting a knob, when the overall size of the installation mechanism needs to be adjusted to install transformers of different sizes, the knob is rotated to rotate the threaded rod, thereby moving the threaded sleeve to drive the bracket to deflect, thereby controlling the expansion or retraction of the telescopic plate, thereby changing the position of the columnar block, and realizing the installation of transformers of different sizes.

[0027] 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.

[0028] Reference Figure 1-Figure 2 The utility model provides an embodiment: a mounting structure for a small-sized transformer for household appliances that is easy to disassemble and assemble quickly, comprising a mounting seat 1, the inner wall of the mounting seat 1 is slidably connected with two groups of telescopic plates 2, the overall size of the mounting seat 1 can be adjusted by the two groups of telescopic plates 2, so as to install transformers of different sizes, the outer wall of the telescopic plate 2 is detachably connected with a mounting plate 3, a transformer body 4 is fixedly connected with the two groups of mounting plates 3 at intervals, a columnar block 5 is fixedly connected with the outer wall of the telescopic plate 2, the outer wall of the columnar block 5 is plugged with the inner wall of the mounting plate 3, a circular groove is provided on the inner wall of the mounting plate 3, the circular groove can be aligned with the columnar block 5 and put on, so that the transformer body 4 is connected to the mounting seat 1 together, a pull rod 6 is slidably connected with the inner wall of the pull rod 6, two groups of card blocks 8 are slidably connected with the inner wall of the pull rod 6, the interval between the two groups of card blocks 8 is elastically connected by a reset spring 7, the two ends of the reset spring 7 are respectively fixedly connected with the inner ends of the two groups of card blocks 8, and the two groups of card blocks 8 are fixedly connected with the inner ends of the two groups of card blocks 8. The outer end of the block 8 is set as an inclined surface. When the cylindrical block 5 is put on the circular groove on the surface of the mounting plate 3, the inner wall squeezes the inclined surface of the block 8 to squeeze the reset spring 7 and retract it. At the same time, the elastic force generated by the deformation of the reset spring 7 gives the two groups of blocks 8 an outward thrust to reset them. When the cylindrical block 5 is completely put on the circular groove on the surface of the mounting plate 3, the reset spring 7 pushes the block 8 out. At this time, the inner end of the block 8 is clamped with the outer wall of the mounting plate 3 to fix the transformer body. 4 is fixed on the mounting base 1, and the block 8 will clamp the notch of the column block 5 by the outer plane. When the two groups of blocks 8 are pressed inward, the outer planes of the blocks 8 are retracted, and the pull rod a6 can be pulled outward. At this time, the inner wall of the column block 5 will squeeze the inclined surface of the block 8 to retract it. When the block 8 is completely retracted, its side wall will abut against the inner wall of the column block 5 to prevent it from resetting. The inner wall of the column block 5 contacts the side wall of the block 8. At this time, the mounting plate 3 can be removed together with the transformer body 4.

[0029] Reference Figure 1 and Figure 3The inner wall of the mounting seat 1 is rotatably connected with a threaded rod 9, and the outer end of the threaded rod 9 is fixedly connected with a knob 10. Turning the knob 10 can drive the threaded rod 9 to rotate. The outer wall of the threaded rod 9 is threadedly connected with two groups of threaded sleeves 11. The inner walls of the two groups of threaded sleeves 11 are set as reverse threads. As the threaded rod 9 rotates, they move closer to or separate from each other. The outer wall of the threaded sleeve 11 is hinged with a bracket 12. The end of the bracket 12 is hinged to the inner side wall of the telescopic plate 2. The threaded sleeves 11 move closer to or separate from each other, which will also drive the angle of the bracket 12 to deviate, thereby pulling or pushing out the telescopic plate 2, changing the width of the entire mounting mechanism, and thus changing the position of the columnar block 5 to adapt to the installation of transformers of different sizes.

[0030] Working principle: When installing the transformer, align the circular groove on the surface of the mounting plate 3 with the cylindrical block 5 and put it on. During this process, the inner wall of the mounting plate 3 will squeeze the inclined surface of the block 8 to retract it. When the transformer is completely attached to the mounting seat 1, the block 8 pops out and clamps the outer wall of the mounting plate 3 under the action of the reset spring 7, fixing the transformer on the mounting mechanism. When it needs to be removed, press the block 8 inward until its outer outer wall no longer presses against the notch of the cylindrical block 5, pull the pull rod 6 outward until the block 8 is completely retracted and presses against the inner wall of the cylindrical block 5. At this time, the transformer body 4 can be removed. If it is necessary to install transformers of different sizes and adjust the position of the cylindrical block 5, turn the knob 10 to rotate the threaded rod 9, so that the two groups of threaded sleeves 11 move closer to or separate from each other, causing the angle of the bracket 12 to change, driving the two groups of telescopic plates 2 to retract or expand to both ends, adjusting the position of the cylindrical block 5, and thus installing transformers of different sizes.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
