Description

Technical Field

[0001] This utility model relates to the technical field of voltage regulators, and in particular to a power voltage regulator that is easy to maintain. Background Technology

[0002] As an electronic device, the core function of a voltage regulator is to accurately convert fluctuating or unstable input voltage into a stable output voltage, thereby building a protective barrier for various electrical devices, shielding them from voltage fluctuations and ensuring stable and reliable operation. Structurally, a voltage regulator includes key components such as a voltage regulation circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit quickly initiates a series of actions: first, it samples the voltage; then, it compares the sampled value with a preset value; next, it amplifies the comparison result; and finally, it drives the servo motor to rotate. The rotation of the servo motor causes a change in the position of the voltage regulator's carbon brushes, automatically adjusting the coil turns ratio to achieve a stable output voltage.

[0003] However, in practical applications, core components such as control circuits, servo motors, main transformers, and auxiliary transformers are mostly fixedly installed inside the housing using brackets. Given the relatively small space inside the housing, this poses a significant obstacle to subsequent maintenance and repair work, not only making repairs extremely difficult but also slowing down the repair process. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one objective of this utility model is to provide a power voltage stabilizer that is easy to maintain, which allows the support plate and support frame to be removed from the inside of the housing, greatly facilitating the maintenance and repair of the voltage stabilizer, significantly improving the ease of operation, and accelerating the repair process.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a power voltage stabilizer that is easy to maintain, comprising a housing, two sets of guide rails, multiple locking components, a support frame, and a support plate. The housing has an opening connected to a door via a hinge. The two sets of guide rails are respectively installed on the upper and lower inner walls of the housing, and each guide rail has a sliding plate slidably connected to it, with a slot on the sliding plate. Multiple locking components are respectively arranged in pairs on opposite inner walls of the housing, and each locking component is connected to a corresponding sliding plate and engages with a corresponding slot. The support frame and the support plate are respectively connected to the corresponding sliding plates, and the support frame has a main transformer and a secondary transformer, while the support plate has a circuit board and a switch.

[0007] In addition, the power regulator that is easy to maintain, as proposed above, may also have the following additional technical features:

[0008] Specifically, the locking assembly includes a positioning rod, a locking plate, a spring, and a locking plate. The inner sidewall of the housing is provided with multiple fixed plates in pairs, and the positioning rod is disposed between two of the fixed plates. One end of the locking plate is rotatably connected to the positioning rod, and the other end of the locking plate has a first groove, which fits into the locking groove. The spring is disposed within the first groove. The guide rail has a second groove on its side facing away from the positioning rod, and one end of the locking plate is connected to the spring, while the other end of the locking plate fits into the second groove.

[0009] Specifically, the support plate has multiple first heat dissipation holes, and the support plate is equipped with multiple cooling fans inside.

[0010] Specifically, a plurality of second heat dissipation holes are provided on the two opposite inner walls of the housing.

[0011] Specifically, the housing is provided with multiple protective rods inside, and the multiple protective rods are distributed on both sides of the main transformer and the auxiliary transformer.

[0012] Compared with the prior art, the present invention has the following advantages: the locking component can lock or unlock the slide plate, thereby facilitating the removal of the support plate and support frame from the housing, which greatly facilitates the maintenance and repair of the voltage regulator, significantly improves the ease of operation, and speeds up the repair process.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention of a power voltage stabilizer that is easy to maintain.

[0021] like Figures 1 to 3 As shown, the easy-to-maintain power regulator of this utility model embodiment may include a housing 1, two sets of guide rails 2, multiple locking components 3, a support frame 4, and a support plate 5.

[0022] The opening of the housing 1 is connected to a door via a hinge. Two sets of guide rails 2 are respectively installed on the upper inner wall and the lower inner wall of the housing 1, and a slide plate 6 is slidably connected to each guide rail 2. The slide plate 6 is provided with a slot 60.

[0023] It should be noted that each set includes two guide rails 2, and the guide rails 2 are set along the depth direction of the housing 1. The guide rails 2 are fixedly set on the inner upper wall or inner lower wall of the housing 1, and the guide rails 2 are provided with T-shaped grooves.

[0024] Furthermore, the cross-section of the slide plate 6 is "I" shaped to prevent the slide plate 6 from separating from the guide rail 2. The slide plate 6 is slidably connected to the T-shaped groove. The slot 60 is set near the opening of the housing 1 and is set perpendicular to the length of the slide plate 6.

[0025] Multiple locking components 3 are respectively arranged in pairs on the opposite inner walls of the housing 1, and the multiple locking components 3 are respectively connected to the corresponding slide plate 6 and fit with the corresponding slot 60.

[0026] It should be noted that the locking component 3 is configured to correspond with the skateboard 6. The locking component 3 can fix the skateboard 6 inside the housing 1 to prevent the skateboard 6 from moving.

[0027] The support frame 4 and the support plate 5 are respectively connected to the corresponding slide plate 6, and the support frame 4 is equipped with the main transformer and the auxiliary transformer, and the support plate 5 is equipped with the circuit board and the switch.

[0028] In an embodiment of this utility model, the support plate 5 is a square frame structure, and the support plate 5 is fixed to the slide plate 6 below by bolts to support the main transformer and the auxiliary transformer.

[0029] Furthermore, the support frame 4 is located above the support plate 5 and is fixed to the upper slide plate 6 by bolts to support the circuit board and the switch.

[0030] In one embodiment of this utility model, such as Figure 3 As shown, the locking assembly 3 includes a positioning rod 30, a locking plate 31, a spring 32, and a locking plate 33. Multiple fixing plates 7 are arranged in pairs on the inner sidewall of the housing 1, and the positioning rod 30 is positioned between two fixing plates 7. One end of the locking plate 31 is rotatably connected to the positioning rod 30, and the other end of the locking plate 31 has a first groove 310, which fits snugly against the locking slot 60. The spring 32 is positioned within the first groove 310. The guide rail 2 has a second groove 20 on its side opposite to the positioning rod 30, and one end of the locking plate 33 is connected to the spring 32, while the other end of the locking plate 33 fits snugly against the second groove 20.

[0031] It should be noted that the card plate 33 described in this embodiment is an L-shaped plate, and the card plate 33 is slidably connected to the first groove 310. When the card plate 33 is in contact with the second groove 20, the spring 32 is in a stretched state.

[0032] Furthermore, when the skateboard 6 is locked, the relevant personnel rotate the locking plate 31 and place the locking plate 31 in the slot 60. Then, they pull the card plate 33 away from the first groove 310. The card plate 33 pulls the spring 32 to extend until the card plate 33 is in contact with the second groove 20. At this time, the stretched spring 32 generates a certain pulling force on the card plate 33 so that the card plate 33 is in close contact with the second groove 20, thereby locking the skateboard 6.

[0033] In one embodiment of this utility model, such as Figure 1 As shown, the support plate 5 has multiple first heat dissipation holes 50 distributed on it, and the support plate 5 has multiple cooling fans 8 inside it.

[0034] In the embodiments of this utility model, the cooling fan 8 can effectively dissipate heat from the main transformer and auxiliary transformer on the support plate 5, thereby helping to extend the lifespan of the main transformer and auxiliary transformer.

[0035] Furthermore, such as Figure 1As shown, multiple second heat dissipation holes 9 are provided on the two opposite inner walls of the housing 1. The oppositely arranged second heat dissipation holes 9 help the air to circulate inside the housing 1 and improve the heat dissipation effect of the entire voltage regulator.

[0036] In one embodiment of this utility model, such as Figure 2 As shown, the interior of the housing 1 is provided with multiple protective rods 10, which are distributed on both sides of the main transformer and the auxiliary transformer.

[0037] It should be noted that the two ends of the protective rod 10 are T-shaped structures, and the protective rod 10 can be fixed to the inner wall of the housing 1 with bolts. The main transformer and the auxiliary transformer can be fixed to the support plate 5 with bolts. The protective rod 10 can protect the main transformer and the auxiliary transformer and prevent them from tilting during transportation.

[0038] Specifically, when the voltage regulator needs to be inspected, the relevant personnel open the box door and pull the card plate 33 to separate from the second groove 20. Then, they rotate the locking plate 31 upward to separate the locking plate 31 from the card slot 60, thereby releasing the limit on the slide plate 6. Then, the support plate 5 can be pulled to move the support plate 5 to the outside of the housing 1, which facilitates the maintenance and inspection of the main transformer and the auxiliary transformer. Similarly, when the voltage regulating circuit or control circuit on the support frame 4 needs to be maintained and inspected, the support frame 4 can simply be moved out of the housing 1, making maintenance more convenient and effectively improving maintenance efficiency.

[0039] In summary, the power regulator of this utility model, which is easy to maintain, can lock or unlock the slide plate using a locking component, thereby facilitating the removal of the support plate and support frame from the housing. This greatly facilitates the maintenance and repair of the regulator, significantly improves operational convenience, and speeds up the repair process.
