Description

Technical Field

[0001] This application relates to the field of electrical enclosure technology, and in particular to an electrical enclosure with a padlock structure. Background Technology

[0002] As a key component protecting internal electrical components, one of the core functions of an electrical enclosure is to provide a high level of sealing protection against the intrusion of external environmental factors such as dust and moisture, ensuring the stability and safety of internal circuits. In some application scenarios, in addition to basic protective functions, it is also necessary to physically control the opening permissions of the electrical enclosure, i.e., to add a physical locking function.

[0003] The existing technology typically employs a separate locking mechanism or latch to physically lock electrical enclosures. This separate design presents two key drawbacks: first, it adds extra components and assembly steps, leading to structural redundancy and increased costs; second, adding a latch often requires additional fastening holes on the enclosure, directly compromising its integrity and introducing new sealing failure points, thus creating a technical contradiction with the high protection level sought by electrical enclosures.

[0004] Therefore, when adding physical locking functions to electrical enclosures, existing technologies often sacrifice the original sealing performance of the enclosures, which creates a technical conflict between the need for locking functions and the design goal of high protection levels. Utility Model Content

[0005] To address the technical problem that adding physical locking functions to existing electrical enclosures leads to a decrease in protection level due to compromise of enclosure integrity, this application provides an electrical enclosure with a padlock structure.

[0006] This application provides an electrical box cover with a padlock structure, which adopts the following technical solution: An electrical box cover with a padlock structure includes an electrical box cover shell and a knob. A locking structure portion extends from the outer wall of the electrical box cover shell. The knob is provided with a cooperating locking portion, which is used to cooperate with the locking structure portion to form a lock hole when the knob is rotated to a predetermined locking position.

[0007] By adopting the above technical solution, this application integrates the keyhole structure and the operating knob into a single design. The user only needs to rotate the knob to a specific position, and the knob's locking mechanism, together with the locking structure on the housing, forms a keyhole through which a padlock can pass. This design eliminates the need for additional holes or separate latches on the electrical enclosure, thus achieving physical locking without compromising the enclosure's sealing integrity, and helping to maintain the high protection level of the electrical enclosure.

[0008] Optionally, the locking structure includes a protruding structure extending from the outer wall of the electrical box housing, the protruding structure having a groove.

[0009] By adopting the above technical solution, this locking structure, which consists of protrusions and grooves, is more simplified and helps to reduce the risk of locking failure due to corrosion or jamming of independent moving parts, thus improving long-term reliability in outdoor or humid environments.

[0010] Optionally, the electrical box housing has a knob mounting hole for mounting the knob, and a knob seal is provided between the knob and the knob mounting hole.

[0011] By adopting the above technical solution and setting a dedicated seal at the knob, a dynamic component, the rotation gap can be effectively sealed. This is a key measure to maintain a high protection level of the whole machine while achieving the locking function.

[0012] Optionally, the knob seal is a skeleton oil seal.

[0013] By adopting the above technical solutions and selecting a mature and reliable dynamic sealing component such as a skeleton oil seal, a reliable seal can be provided for the rotating knob, further enhancing the overall protective capability of the electrical enclosure.

[0014] Optionally, the knob is internally fitted with a knob magnet for sensing by a sensor; the electrical box housing is also equipped with a sensor for sensing changes in the magnetic field of the knob magnet to determine the rotational position of the knob.

[0015] By adopting the above technical solution, the rotation position of the knob is detected by non-contact magnetic induction. Compared with mechanical contact detection, this can reduce the impact of physical wear and poor electrical contact, and help improve the long-term reliability and service life of the position detection function.

[0016] Optionally, the electrical box housing is provided with a limiting boss, and the knob is provided with a limiting wall that cooperates with the limiting boss. The cooperation between the limiting boss and the limiting wall is used to limit the rotation range of the knob within a predetermined angle.

[0017] By adopting the above technical solution and utilizing a simple mechanical limiting method, the rotation range of the knob is limited. This structure reduces the possibility of excessive knob rotation due to misoperation, thereby helping to prevent potential internal electrical state switching errors and improving the operational safety of the equipment.

[0018] Optionally, the predetermined angle is 90°.

[0019] By adopting the above technical solution, the rotation angle is set to 90°, which conforms to the common operating habit of "rotation-lock" in ergonomics, making the user operation more intuitive and convenient.

[0020] Optionally, the top surface of the knob is provided with an indicator mark, and the electrical box cover is provided with a position symbol corresponding to the indicator mark.

[0021] By adopting the above technical solution, users are provided with intuitive visual feedback, enabling them to clearly determine the current rotation position of the knob, thus improving the convenience and accuracy of operation.

[0022] Optionally, it also includes a button, and the electrical box cover is provided with a button through hole; the button is reciprocally inserted through the button through hole.

[0023] By adopting the above technical solution, an additional human-machine interface input channel is integrated into the electrical enclosure, enriching the equipment's operational functions without significantly altering the main structure.

[0024] Optionally, a button seal is also provided between the button and the button through hole.

[0025] By adopting the above technical solution, a sealing element is added to the reciprocating button, which makes up for the potential sealing risks introduced by adding the button, so that the additional function will not be at the expense of the overall protection performance.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the lock hole structure with the operating knob into a single design, a physical locking function is achieved without compromising the sealing integrity of the electrical enclosure, which helps maintain the high protection level of the electrical enclosure.

[0027] 2. The locking structure adopts a concave-convex fit, which simplifies the structure and, compared with the traditional independent latch, helps to reduce the possibility of excessive rotation of the knob due to misoperation, thus improving the operational safety of the equipment.

[0028] 3. By setting a limiting boss and a limiting wall, the rotation range of the knob is mechanically limited, which can effectively avoid production accidents caused by excessive rotation of the knob due to misoperation and improve the operational safety of the equipment.

Detailed Implementation

[0036] The following combination Figures 1 to 6 This application will be described in further detail.

[0037] This embodiment discloses an electrical box cover with a padlock structure.

[0038] Reference Figures 1 to 2 The structure of the electrical box cover with padlock in this embodiment is shown from both an overall and magnified perspective. The electrical box cover includes an electrical box cover shell 10 and a knob 20 mounted on the electrical box cover shell 10.

[0039] Reference Figures 2 to 4 The overall structure of the electrical enclosure is based on the electrical enclosure shell 10. In this embodiment, the electrical enclosure shell 10 has a knob mounting hole 12 for mounting the knob 20, and a knob seal 22 is provided between the electrical enclosure shell 10 and the knob mounting hole 12. The knob seal 22 can be a skeleton oil seal for providing dynamic sealing. In another embodiment, other mounting methods that do not damage the sealing performance of the electrical enclosure shell 10 can be used. (Refer to...) Figure 2 A locking structure 11 is provided on the outer wall of the electrical box housing 10. In this embodiment, the locking structure 11 is a protrusion 11a extending from the outer wall of the electrical box housing 10, wherein a groove 11b is provided on the protrusion 11a.

[0040] The knob 20 is rotatably mounted at the knob mounting hole. The top surface of the knob 20 is provided with an indicator (e.g., an arrow indicator), and the electrical box housing 10 is provided with position symbols corresponding to the indicator (e.g., "ON" and "OFF"). The combination of the indicator and the position symbols provides the operator with intuitive visual feedback on the rotational position of the knob 20, facilitating accurate judgment of its current status. The knob 20 is provided with a locking part; in this embodiment, the locking part is a locking part 21 provided on the side wall of the knob 20. The locking part 21 is used to engage with the groove 11b when the knob 20 is rotated to a predetermined locking position, jointly defining a lock hole for locking by an external padlock 40.

[0041] Reference Figure 4 and Figure 5 To detect the rotational position of the knob 20, a knob magnet 23 is embedded inside the knob 20. An operating panel with a sensor is fixed inside the electrical box housing 10. The sensor faces the knob magnet 23 and senses changes in its magnetic field to determine the rotational position of the knob 20. To limit the rotational range of the knob 20, a limiting boss surrounding the knob mounting hole is provided on the electrical box housing 10. A limiting wall 24, which mates with the limiting boss, is provided at the bottom of the knob 20. The limiting boss and the limiting wall 24 cooperate to limit the rotational range of the knob 20 within a predetermined angle. In this embodiment, the predetermined angle is 90°.

[0042] The electrical enclosure in this embodiment may also include a button assembly. (See reference...) Figure 1 and Figure 6 The electrical box housing 10 also has a button through-hole 13. In this embodiment, the button assembly includes a button 30, a washer 32, and a button spring 34. The button rod 31 of the button 30 is reciprocally inserted into the button through-hole 13, and a button seal is provided between the button 30 and the button through-hole. To increase the functionality of the solution, a button magnet 33 can be embedded inside the button 30. A button sensor is provided on the operation panel to sense changes in the magnetic field of the button magnet 33 to determine the pressed state of the button 30. The washer 32 is sleeved on the button rod 31 and abuts against the outside of the button seal. The button spring 34 is used to provide a return force for the button 30.

[0043] The implementation principle of an electrical enclosure with a padlock structure according to an embodiment of this application is as follows: The operator rotates the knob 20 by referring to the indicator and position symbols. When rotated to the locked position, the engaging locking part 21 aligns with the groove 11b to form a lock hole, through which the padlock 40 can pass. During this process, the sensor detects the change in the magnetic field of the knob magnet 23 to determine the knob state. When a pressing operation is required, the button 30 is pressed. After the pressing action is completed, the button spring 34 resets it. The knob seal 22 and the button seal provide a sealed protection for the interior of the electrical enclosure.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
