Description

Technical Field

[0001] This utility model relates to the field of waterproofing, and in particular to a waterproof box. Background Technology

[0002] Currently, waterproof boxes are widely used in indoor and outdoor electrical equipment, primarily to ensure electrical safety and prevent water from entering plugs, sockets, and their connecting parts, thus avoiding dangers such as short circuits, leakage, or electric shock. Common waterproof boxes typically consist of an upper cover and a lower shell, with the upper cover opening and closing via a hinge structure. The connection between the upper cover and the lower shell is usually achieved through a pin or pivot. The installation of the pin is particularly important to ensure the long-term service life of the waterproof box.

[0003] In existing technologies, the pin is fixed to either the upper or lower housing, but not to the other, allowing the upper housing to rotate and open around the pin. Common pin fixing methods often employ interference fits or thermoforming. However, these designs have the following drawbacks: First, interference fits or thermoforming require specialized tooling and fixtures, increasing both the number of steps and equipment costs. Second, the installation process can easily lead to irreversible damage to the product. Furthermore, during later use, as the plastic housing ages and wears, the pin is highly likely to fall off and be lost.

[0004] Therefore, there is an urgent need for a waterproof box that allows for easy installation of the pin and is not easily detached, in order to ensure the long service life of the waterproof box. Utility Model Content

In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0022] The terms “comprising,” “including,” and similar terms as used herein should be understood as open-ended terms, meaning “including / including but not limited to,” implying that other content may also be included. The term “based on” means “at least partially based on.” The term “one embodiment” means “at least one embodiment”; the term “another embodiment” means “at least one additional embodiment,” and so on.

[0023] Traditional waterproof socket boxes fix a pin to one of the upper or lower housings using interference fit or thermoforming, while leaving it unfixed to the other housing, allowing the upper housing to rotate around the pin to open and close. However, this method requires specialized tooling and fixtures, making installation cumbersome and prone to product damage. Furthermore, the pin may detach and be lost during later use.

[0024] According to various embodiments of the present invention, the waterproof box prevents the pin from dislodging from the pin hole seat of the connecting part and the pin hole seat of the mating part by adding a stop member to the shell connecting part to fix the pin. Furthermore, the stop member is protected from external damage by an enveloping structure, thereby improving the reliability of the stop member.

[0025] Figure 1 A schematic diagram of a waterproof box according to an embodiment of the present invention is shown. (Refer to...) Figure 1 An exemplary waterproof box 10 includes a first housing 11, a second housing 12, and a connecting assembly 13. The second housing 12 is detachably mounted on the first housing 11 via the connecting assembly 13 and defines a chamber 18 with the first housing 11 to accommodate a socket and plug (not shown). To ensure the electrical safety of the user when using the socket and plug, it is necessary to ensure that the interior of the waterproof box 10 is protected from external environmental damage, such as mechanical damage, moisture penetration, and chemical corrosion. Therefore, both the first housing 11 and the second housing 12 can be made of, for example, plastic materials, or other materials with good electrical insulation, heat resistance, and abrasion resistance.

[0026] Figure 2 A partial structural schematic diagram of the first housing 11 according to an embodiment of the present invention is shown. (Referring to...) Figure 1 and Figure 2 The connecting assembly 13 includes a connecting portion 14, a connecting mating portion 15, a pin 16, and a stop 17. The connecting portion 14 is formed on the first housing 11 and includes a first side 143 and a second side 144 opposite to the first side. The connecting portion 14 includes at least one connecting pin hole seat 141 and an envelope structure 142 arranged adjacent to the first side 143. The connecting mating portion 15, which mates with the connecting portion 14, is formed on the second housing 12 and includes at least one mating pin hole seat 151.

[0027] The pin 16 is configured to be inserted from the first side 143 of the first housing 11 into at least one connecting pin hole seat 141 and at least one mating pin hole seat 151 when the connecting part 14 and the connecting mating part 15 are installed and engaged, so as to connect the first housing 11 and the second housing 12. The pin 16 may be made of, for example, stainless steel, or other metal materials with good corrosion resistance, wear resistance and mechanical properties.

[0028] The stop 17 may be formed on the first housing 11 and is at least partially located within the envelope structure 142. The stop 17 is configured to prevent the pin 16 from disengaging from the connecting pin seat 141 and the mating pin seat 151 when the pin 16 is inserted into the connecting pin seat 141 and the mating pin seat 151.

[0029] In one embodiment, the stop 17 may be an elastic stop configured to elastically deform in response to a force, allowing the pin 16 to be inserted from the first side 143 of the first housing 11 into the connecting pin seat 141 and the mating pin seat 151. When the pin 16 is fully inserted, the force on the stop 17 is removed, and the elastic deformation returns to its initial state, preventing the pin 16 from dislodging from the connecting pin seat 141 and the mating pin seat 151 from the first side 143 of the first housing 11. The stop 17 may be made of, for example, plastic material or stainless steel sheet, or other materials with good resilience, corrosion resistance, and wear resistance.

[0030] In one embodiment, the axial projection of the pin 16 at least partially overlaps with the stop 17, ensuring that the stop 17 can prevent the pin 16 from dislodging from the connecting pin hole seat 141 and the mating pin hole seat 151 on the first side 143 of the first housing 11.

[0031] In one embodiment, the stop 17 may be integrally formed on the first housing 11. It is understood that in other embodiments, the stop 17 and the first housing 11 may also be detachable and can be installed together by a variety of suitable means, such as snap-fit ​​connection, screw connection or adhesive connection.

[0032] In one embodiment, the envelope structure 142 may be a fully enclosed envelope or a semi-enclosed envelope to protect the stop 17 inside the envelope from damage by external forces. The envelope structure 142 may be made of, for example, plastic materials, or other materials with good corrosion resistance and wear resistance.

[0033] In one embodiment, the envelope structure 142 may be integrally formed on the connecting portion 14. In other embodiments, the envelope structure 142 and the connecting portion 14 may also be detachable and can be installed together in a variety of suitable ways, such as snap-fit ​​connection, screw connection, or adhesive connection.

[0034] In one embodiment, a groove 1421 may be formed on the envelope structure 142 and coaxially disposed with the connecting pin seat 141 and the mating pin seat 151. The groove 1421 is configured to guide the shaft pin 16 to be inserted into at least one connecting pin seat 141 and at least one mating pin seat 151 via the groove 1421, thereby improving the accuracy and convenience of the assembly process.

[0035] Figure 3 A schematic diagram of the assembled waterproof box 10 according to an embodiment of the present invention is shown; Figure 4 A schematic diagram of the AA cross-section of a waterproof box 10 after assembly according to an embodiment of the present invention is shown.

[0036] Combined with reference Figures 1 to 4 In one embodiment, when the connecting part 14 and the connecting mating part 15 are installed and mated, at least one connecting part pin hole seat 141 and at least one mating part pin hole seat 151 can be arranged alternately.

[0037] In one embodiment, the mating pin seat 151 may include a first mating pin seat 151a disposed on the connecting mating part 15, and the connecting pin seat 141 may include a first connecting pin seat 141a and a second connecting pin seat 141b disposed at a distance from each other on the connecting part 14. The spacing between the first connecting pin seat 141a and the second connecting pin seat 141b can be designed to accommodate the first mating pin seat 151a. It is understood that the number of mating pin seats 151 is not limited to one, and the number of connecting pin seats 141 is not limited to two; they can be set according to actual needs.

[0038] When installing the waterproof box 10, firstly, the first housing 11 and the second housing 12 are fastened together, and the connecting pin hole seat 141 and the mating pin hole seat 151 are fitted together. Next, the pin 16 is inserted from the first side 143 of the first housing 11 through the groove 1421 on the envelope structure 142. The force of the pin 16 insertion causes the stop 17 to elastically deform, allowing the pin 16 to insert into at least one connecting pin hole seat 141 and at least one mating pin hole seat 151. Once the pin 16 is fully inserted, the stop 17 returns to its initial state, forming a physical block on the pin 16, thereby restricting the axial movement of the pin 16 and effectively preventing the pin 16 from falling out.

[0039] In the foregoing exemplary embodiments of this utility model, compared with the prior art, the pin shaft is reliably installed and fixed by utilizing the pin hole seats and stop members on the first and second housings. The stop member is protected by an enveloping structure, which not only prevents damage to the stop member due to external forces but also improves the anti-dislodgement performance of the pin shaft. This waterproof box simplifies installation, improves the reliability and stability of the waterproof box, and extends its service life.
