Description

Technical Field

[0001] The utility model relates to a waterproof box, in particular to a double-layer waterproof box. Background Art

[0002] The double-layer waterproof box is a well-designed protection device for electrical equipment. Its main function is to ensure that the internal electronic components can still work normally in a humid or dusty environment. This waterproof box adopts a double-layer structure design. The inner and outer layers are independent of each other but work together, which greatly enhances the waterproof and dustproof effect. The inner layer is mainly responsible for directly protecting the equipment and preventing the intrusion of moisture and dust; while the outer layer plays a secondary protection role, providing additional safety for the internal equipment even in extreme environments.

[0003] However, there is a significant problem with some waterproof box designs on the market: they do not have a dedicated external pipe interface. This lack leads to many inconveniences in actual use. In particular, when it is necessary to connect an external hose to the inside of the waterproof box, users can only import the hose through the cover of the waterproof box. This method is not only inconvenient to operate, but also has great hidden dangers. That is, after the hose is imported into the waterproof box from the cover, if the user needs to close the cover, the hose will inevitably be squeezed. This squeezing may not only damage the hose and affect its normal function, but more seriously, during the process of closing the cover, the hose may be forced to close due to strong pressure, thereby blocking the normal flow of the fluid. This situation is extremely unfavorable in actual applications and may cause equipment failure or performance degradation, and may even cause safety hazards. Utility Model Content

[0004] In order to overcome the disadvantage that the existing waterproof box can only introduce a hose through the cover plate, so that the waterproof box cannot be closed normally, affecting its airtightness, the technical problem of the utility model is to provide a double-layer waterproof box that can be externally connected to a pipeline.

[0005] The technical implementation scheme of the utility model is: a double-layer waterproof box, including a waterproof box, and also including a fixing ring, a sealing ring and a rotating ring. A connecting hole is opened on the side of the waterproof box, and a disposable hole slot card is arranged at the corresponding position of the connecting hole. The fixing ring is fixedly connected to the outer side of the waterproof box and is located at the corresponding position of the connecting hole. The rotating ring is fixedly connected to a threaded tube. An internal thread is opened on the inner wall of the fixing ring to cooperate with the threaded tube. A sealing ring is arranged at the inner end of the rotating ring. After the rotating ring is rotated, it can cooperate with the fixing ring by a clamping method, and the threaded tube will be inserted into the waterproof box to set up an introduction hose.

[0006] A more excellent optimization solution is that an annular groove is provided on the side of the rotating ring, and the annular groove can be slidably engaged with the outside of the fixed ring.

[0007] A more excellent optimization solution is to further include a limiting block and a clamping block, wherein the limiting blocks arranged opposite to each other are fixedly connected to the rotating ring and the fixed ring, and the clamping block is embedded between the limiting blocks.

[0008] A more excellent optimization solution is to further include a contact plate, which is fixed to the card block.

[0009] A more excellent optimization solution is to further include a waterproof pad, and the outer cover of the rotating ring is provided with a waterproof pad.

[0010] A more excellent optimization solution is to further include a magnetic block, and the clamping block and the limit block are fixedly connected with magnetic blocks that can be magnetically attracted to each other.

[0011] A more excellent optimization solution is to further include a protective cover, and the protective cover is configured on the outside of the rotating ring.

[0012] A more excellent optimization solution is to further include a rubber ring, which is sleeved on the outside of the threaded tube and specifically located at the contact point between the threaded tube and the fixing ring.

[0013] The utility model has the following advantages: the threaded tube is introduced into the waterproof box by rotating the rotating ring, and then the card slot provided on the inner ring of the rotating ring is tightly embedded in the outside of the fixing ring by card connection, so as to achieve the effect of sealing and fixing, and then the protective cover is opened, at which time the rotating ring is fixed to the outside of the waterproof box and forms a stable hole, and the staff can insert the hose into the waterproof box through the threaded tube, thereby solving the problem that the existing hose can only be passed through the cover plate and is squeezed.

[0021] Embodiment: A double-layer waterproof box, such as Figure 1-Figure 5 As shown, it includes a waterproof box 1, which consists of two parts that are connected and have upper openings of different heights, and the two parts are sealed by a cover plate that is rotatably connected by a hinge. A push-type switch is arranged between the cover plate and the waterproof box 1 to achieve the effect of convenient opening and closing. The waterproof box 1 is made of a double-layer inner wall structure, which improves its sealing and waterproof properties while improving its strength of use. It also includes a fixing ring 3, a sealing ring 5 and a rotating ring 6. A connecting hole is opened on the side of the waterproof box 1, the fixing ring 3 is fixedly connected to the outside of the waterproof box 1 and is located at the corresponding position of the connecting hole, the rotating ring 6 is fixedly connected to a threaded tube 4, the inner wall of the fixing ring 3 is opened with an internal thread that can cooperate with the threaded tube 4, a sealing ring 5 is arranged at the inner end of the rotating ring 6, and an annular groove is opened on the side of the rotating ring 6, which can be slidably embedded in the outside of the fixing ring 3, and the threaded tube 4 will be inserted into the waterproof box 1 to set up an introduction hose.

[0022] like Figure 4 and Figure 5 As shown, it also includes a limit block 7 and a clamping block 8. The limit blocks 7 set opposite to each other are fixedly connected to the rotating ring 6 and the fixed ring 3. The clamping block 8 is embedded between the limit blocks 7. The contact plate 9 is fixedly connected to the clamping block 8. The contact plate 9 is convenient for the staff to move the clamping block 8.
