[0003] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide a waterproof control box, which has the advantage of making the box body and the wiring connectors tightly connected and improving the waterproof performance of the control box.
[0004] The above-mentioned objective of this application is achieved through the following technical solution:
[0005] A waterproof control box includes a box body, a seal, and a sealing joint. The sealing joint is installed on the box body. The seal is used to seal the gap between the box body and the sealing joint. The sealing joint is provided with a limiting surface, which is used to limit the position of the seal on the sealing joint.
[0006] By adopting the above technical solution, the gap between the sealing component and the sealing joint is sealed, making the connection between the box and the sealing joint tight and improving the waterproof performance of the control box.
[0007] In a preferred embodiment, this application can be further configured such that: a connecting part is provided on the box body, a sealing joint is connected to the box body through the connecting part, and a limiting groove is provided on the connecting part, the limiting groove being used to limit the position of the sealing element on the connecting part.
[0008] By adopting the above technical solution, the limiting groove limits the position of the seal on the connection part, prevents the seal from shifting and allows the connection part and the seal to come into contact, thereby improving the sealing performance between the connection part and the seal.
[0009] In a preferred embodiment, this application may further be configured to include an end cap for securing the output wire, the end cap having a through hole for the output wire to pass through.
[0010] By adopting the above technical solution, the end cap fixes the output wire, reducing the probability that the output wire will break off from the inside of the box when it is accidentally pulled.
[0011] In a preferred embodiment, this application may be further configured such that the end cap is provided with a pressing element for applying pressure to the output wire.
[0012] By adopting the above technical solution, the pressing component applies pressure to the output wire, thereby achieving the function of fixing the output wire with the end cover.
[0013] In a preferred embodiment, this application may be further configured such that the pressing member has a guide surface for guiding the pressing member and the output wire to come into contact.
[0014] In a preferred embodiment, this application may be further configured to include a contact element for contacting the pressing element and the output wire.
[0015] By adopting the above technical solution, the gap between the pressing component and the output wire can be sealed.
[0016] In a preferred embodiment, this application may be further configured such that the sealing joint has a second limiting surface, which is used to limit the position of the contact element.
[0017] In a preferred embodiment, this application may be further configured such that the sealing joint is provided with a detection groove for detecting whether the sealing joint is loose.
[0018] By adopting the above technical solution, the detection groove can be used to check whether the sealing joint is loose, making it easy to observe the installation quality of the sealing joint.
[0019] In a preferred embodiment, this application may be further configured such that: a waterproof component and a knob are provided on the housing, the knob is mounted on the housing, and the waterproof component is used to improve the sealing between the housing and the knob.
[0020] By adopting the above technical solution, the waterproof component improves the sealing between the box and the knob, resulting in better waterproof performance of the box.
[0021] In a preferred embodiment, the present application may be further configured such that the knob has a limiting portion for limiting the position of the knob on the housing.
[0022] By adopting the above technical solution, the limiting part restricts the position of the knob on the box, making it less likely for the knob to spring back after applying pressure to the waterproof component, thereby reducing the probability of the box springing back in the opposite direction.
[0023] In a preferred embodiment, this application can be further configured such that: the sealing joint is provided with a detection groove for detecting whether the sealing joint is loose, and the box body is provided with a second detection groove, the position of which corresponds to the first detection groove when the sealing joint is installed in place.
[0024] By adopting the above technical solution, the positional offset between detection groove 2 and detection groove 1 can be observed or measured to determine whether the sealing joint is installed in place. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] Reference Figures 1 to 3 The present application discloses a waterproof control box, including a box body 1, a sealing joint 2, a sealing element 3, an end cap 5, and a contact element 6. The sealing joint 2 is installed on the box body 1 and is used to improve the waterproof performance of the control box. The sealing element 3 is used to seal the gap between the box body 1 and the sealing joint 2. The sealing joint 2 and the end cap 5 are threaded together. The end cap 5 is used to fix the output wire 8. The contact element 6 is used to contact the output wire 8. In this embodiment, the sealing element 3 can be a sealing ring, and the contact element 6 can be made of flexible materials such as rubber or silicone.
[0032] The end cap 5 is provided with a through hole 51 and a pressing member 52. The through hole 51 allows the output wire 8 to pass through. The pressing member 52 is used to apply pressure to the output wire 8 through the contact member 6. The pressing member 52 is provided with a guide surface 53, which is used to guide the pressing member 52 and the output wire 8 to abut against each other. In this embodiment, the guide surface 53 is set as an inclined surface. The pressing member 52 can be made of flexible materials such as rubber or silicone.
[0033] The sealing joint 2 is provided with a limiting surface 4, a limiting surface 7, an exhaust hole 21 and a deformation membrane 22. The limiting surface 4 is used to limit the position of the sealing element 3 on the sealing joint 2, the limiting surface 7 is used to limit the position of the contact element 6, the exhaust hole 21 is used to guide the air flow to the deformation membrane 22, and the deformation membrane 22 is used to observe the volume of air passing through the exhaust hole 21.
[0034] The box body 1 is provided with a connecting part 11, a waterproof component 15, a waterproof component 16, and a knob 13. The sealing joint 2 is connected to the box body 1 through the connecting part 11. The sealing joint 2 and the connecting part 11 are connected by threads. The connecting part 11 is provided with a limiting groove 12, which is used to limit the position of the sealing component 3 on the connecting part 11. The knob 13 is installed on the box body 1. The waterproof component 15 is used to improve the sealing between the box body 1 and the knob 13. The waterproof component 16 is used to improve the sealing between the box body 1 and the knob 13. The waterproof component 16 is used to improve the sealing between the fixing screw and the box body 1. The knob 13 is provided with a limiting part 14, which is used to limit the position of the knob 13 on the box body 1, so that the waterproof component 15 and the knob 13 abut against each other. In this embodiment, the waterproof component 15 and the waterproof component 16 can be made of flexible materials with sealing effect such as rubber, silicone, or rubber.
[0035] When installing the sealing joint 2, the sealing element 3 is fitted onto the sealing joint 2, and one end of the sealing joint 2 extends into the connecting part 11. By rotating the sealing joint 2, one side of the sealing element 3 abuts against the limiting groove 12 on the connecting part 11, and the other side abuts against the limiting surface 4 on the sealing joint 2, thereby sealing the gap between the sealing joint 2 and the box body 1. After the contact element 6 and the pressing element 52 are squeezed, they deform, causing the air in the cavity formed by the pressing element 52, the contact element 6 and the sealing joint 2 to flow from the exhaust hole 21 to the deformation membrane 22, causing the deformation membrane 22 to deform, so that the pressing element 52 can fully squeeze the contact element 6. By observing the change of the deformation membrane 22, it is ensured that the end cover 5 is installed in place.
[0036] When installing the knob 13, the limiting part 14 extends into the box body 1, causing the knob 13 to compress the waterproof component 15 on the box body 1. This allows the waterproof component 15 to seal the gap between the knob 13 and the box body 1. With the waterproof component 15 in a compressed state, the limiting part 14 abuts against the box body 1, thus limiting the position of the knob 13 on the box body 1. This makes it less likely for the knob 13 to spring back after applying pressure to the waterproof component 15, and improves the sealing performance of the box body 11. The limiting parts 14 are evenly distributed on the knob 13, making the pressure applied by the knob 13 to the waterproof component 15 more uniform. In this embodiment, the number of limiting parts 14 can be set according to actual needs. When installing the fixing screw, the fixing screw abuts against the waterproof component 16, thus ensuring good sealing performance of the box body 1 while the fixing screw fixes the box body 1.
[0037] The output wire 8 is passed through the sealing joint 2, the contact 6, and the end cover 5. The contact 6 and the output wire 8 are in contact. The end cover 5 is rotated so that the contact 6 contacts the pressing member 52 on the end cover 5 and the limiting surface 7 on the sealing joint 2. The end cover 5 is rotated continuously so that the contact 6 abuts against the pressing member 52, the limiting surface 7, and the output wire 8, thereby sealing the gap between the sealing joint 2 and the output wire 8.
[0038] Reference Figure 4 In another embodiment, the sealing joint 2 is provided with a detection groove 9, which is used to detect whether the sealing joint 2 is loose. The box body 1 is provided with a detection groove 10, which is positioned corresponding to the detection groove 9. The sealing joint 2 is determined to be installed in place by observing or measuring the positional offset between the detection groove 10 and the detection groove 9.
[0039] The implementation principle of this embodiment is as follows: the sealing element 3 seals the gap between the box body 1 and the sealing joint 2, so that the box body 1 and the sealing joint 2 are tightly connected, and the waterproof performance of the control box is better. The sealing joint 2 is provided with a contact element 6 for contacting the pressing element 52 and the output wire 8, so that the gap between the pressing element 52 and the output wire 8 is sealed, and the end cover 5 seals the gap between the output wire 8 and the sealing joint 2 while fixing the output wire 8.
[0040] The embodiments described in this specific implementation are 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.
