It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0035] The specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0036] Referring to Figures 1 to 5 , this embodiment provides an integrated switch box, which includes a cabinet body 1, an electrical component 2, a power supply shaft 3, a reverse prevention component 4 and a spring-back component 5. The interior of the cabinet body 1 is partitioned into an upper space 11 and a lower space 12; the electrical component 2 is installed in the upper space 11; the power supply shaft 3 includes a bracket 31, a rotating shaft 32, a power cord 33 and a socket 34. The bracket 31 is fixed in the lower space 12, the rotating shaft 32 is rotatably installed on the bracket 31, the power cord 33 is wound around the rotating shaft 32, and one end of the power cord 33 is connected to the electrical component 2 and the other end is connected to the socket 34; the reverse prevention component 4 is installed between the rotating shaft 32 and the bracket 31, and the reverse prevention component 4 has a reverse prevention state that prevents the power cord 33 from retracting and an avoidance state that disengages from the rotation of the rotating shaft 32; the spring-back component 5 is installed between the rotating shaft 32 and the bracket 31, and the spring-back component 5 is used to drive the power cord 33 to retract when the reverse prevention component 4 is in the avoidance state.

[0037] Cabinet body 1

[0038] Specifically, the upper space 11 is provided with a cabinet door 13, and the lower space 12 is of a double-sided open structure. It is easy to understand that the double-sided open means that a set of opposite faces of the lower space 12 are both open, forming a frame structure as a whole. The upper space 11 can ensure the use safety through the cabinet door 13, and the lower space 12 being set as a double-sided open structure is convenient for the installation of the power supply shaft 3 and the outgoing line.

[0039] Furthermore, the bottom end of the cabinet body 1 is provided with supporting wheels 14, and the side wall of the cabinet body 1 is provided with a telescopic pull rod 15. A suitcase-like structure is formed by the supporting wheels 14 and the telescopic pull rod 15, making it more convenient to move.

[0040] Electrical component 2

[0041] It is easy to understand that the electrical component 2 is a mature structure in the art, and specifically includes a circuit breaker, a contactor, an intermediate relay, a thermal relay, a button, an indicator light, a universal conversion switch, a travel switch, etc.

[0042] Power supply shaft 3

[0043] It is easy to understand that the power supply shaft 3 mainly serves as an intermediate medium for connecting the electrical equipment to the electrical component 2, and can avoid the direct connection between the electrical equipment and the electrical component 2.

[0044] Specifically, the bracket 31 of the power supply shaft 3 can be fixed in the lower space 12 of the cabinet body 1 by bolts, magnetic attraction or other common methods.

[0045] Furthermore, the bracket 31 is provided with a wire outlet, through which the power cord 33 is led to the outside, and a brush 35 for cleaning the power cord 33 is provided at the wire outlet. The brush 35 can timely clean the debris on the power cord 33 to prevent the power cord 33 from bringing the debris into the bracket 31 and affecting the winding of the power cord 33.

[0046] It should be noted that at least one power shaft 3 is installed in the lower space 12 , and of course two or even more power shafts 3 may be installed. For example, in this embodiment, two power shafts 3 are installed in the lower space 12 .

[0047] Backflow prevention component 4

[0048] Specifically, the anti-return assembly 4 includes a ratchet 42 and a pawl 41; the pawl 41 is mounted on the bracket 31; the ratchet 42 is coaxially fixed on the rotating shaft 32; when the pawl 41 is engaged with the ratchet 42, the anti-return assembly 4 is in an anti-return state, and when the pawl 41 is disengaged from the ratchet 42, the anti-return assembly 4 is in an avoidance state. When in use, the power cord 33 is pulled out, and the ratchet 42 cooperates with the pawl 41 to put the anti-return assembly 4 in an anti-return state, at which time the power cord 33 can be fixed at a target length; after use, the clamp is manually moved to disengage the ratchet 42, at which time the anti-return assembly 4 is in an avoidance state, and the power cord 33 can be pulled freely.

[0049] More specifically, the rotating shaft 32 extends outward from the bracket 31 to form an extended end 321, the ratchet 42 is fixed on the extended end 321, a swing rod 43 is installed on the bracket 31, one end of the swing rod 43 is hinged on the bracket 31, the pawl 41 is hinged on the swing rod 43, and the pawl 41 is engaged with the ratchet 42 by its own gravity and the swing rod 43. In the natural state, the pawl 41 is engaged with the ratchet 42 to put the anti-return assembly 4 in the anti-return state. When it is necessary to switch to the avoidance state, it is only necessary to lift the swing rod 43 upward, and the swing rod 43 drives the pawl 41 to disengage the ratchet 42, thereby completing the switching of the anti-return assembly 4 from the anti-return state to the avoidance state.

[0050] Rebound component 5

[0051] Specifically, the rebound component 5 is a coil spring 51, which is wound around the rotating shaft 32 and has one end connected to the bracket 31 and the other end connected to the rotating shaft 32. When the power cord 33 is pulled out, the coil spring 51 deforms to store energy; when the anti-return component 4 is in the avoidance state, the coil spring 51 releases energy to drive the rotating shaft 32 to rotate, thereby completing the automatic winding of the power cord 33, improving the winding efficiency and making it more convenient to use.

[0052] More specifically, a fixing rod 52 is provided on the bracket 31, and one end of the coil spring 51 is connected to the fixing rod 52. The installation is more convenient and the spatial layout is more reasonable.

[0053] In other embodiments, the resilient component 5 can also be a servo motor. The housing of the servo motor is fixed relative to the bracket 31, and the output shaft is coaxially and fixedly connected to the rotating shaft 32. The servo motor drives the rotating shaft 32 to rotate so as to retract the power cord 33.

[0054] The working principle of the integrated switch cabinet of this embodiment is as follows:

[0055] In use, manually pull the power cord 33 outwards. The power cord 33 is pulled to the target length and stopped under the action of the anti-reverse component 4, and then the electrical equipment is electrically connected to the socket 34. After use, manually lift the swing rod 43, the pawl 41 is disengaged from the ratchet wheel 42, and the anti-reverse component 4 switches to the avoidance state. The power cord 33 automatically retracts under the action of the resilient component 5. When it is necessary to move the switch cabinet, operate the handheld telescopic pull rod 15, and easily push the switch cabinet to the target position through the support wheels 14.

[0056] It should be noted that in actual design, a wireless module and related sensors can be arranged in the cabinet body 1 to enable it to have functions such as data transmission, status display, current protection, voltage reporting, and power-off alarm, so as to avoid the long-term overloading of electrical equipment and the use current exceeding the safe current-carrying capacity of the wire.

[0057] The above are only specific implementation manners of the present invention, enabling those skilled in the art to understand or implement the present invention. Although the above embodiments have been described in detail, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the above embodiments, and they should all be covered by the protection scope of the claims.
