Description

Technical Field

[0001] The utility model relates to the technical field of a junction box, and more specifically, to a P69 strong-sealing junction box. Background Art

[0002] The junction box consists of a box cover, a box body and wiring terminals. The box cover and the box body are separately arranged and are generally connected by snapping or screws. However, the gap at the connection makes the waterproof and dustproof effect low. In addition, when the box cover and the box body are connected by snaps, the snaps are integrated with the box cover or the box body and are made of plastic. After a long time of snapping and separation, the snaps are easy to break or deform and have a low service life. When the box cover and the box body are connected by screws, the screws are small in size and easy to lose after being removed. Therefore, it is necessary to improve the existing junction box. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the sealing effect of the connection between the box cover and the box body of the traditional junction box is relatively weak, so a P69 strong sealing junction box is provided, which has the characteristics of high efficiency dustproof and waterproof.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A P69 strong sealing junction box, comprising a box cover and a box body with an opening, wherein the opening end of the box body is provided with a groove, a sealing ring made of a rubber material is provided in the groove, the sealing ring is higher than the groove, and the cross section of the sealing ring is provided in a V-shape, a Y-shape or a U-shape;

[0006] The opening direction of the sealing ring is consistent with the opening direction of the box body, and a patch with a smooth surface is arranged at the bottom of the box cover at a position corresponding to the sealing ring.

[0007] Preferably, the box cover and the box body are fixedly connected by a metal buckle.

[0008] Preferably: a connecting hole is provided at the open end of the box body, a metal tube is riveted into the connecting hole, and the metal buckle is arranged in a columnar shape, one end of which is rotatably connected to the box cover, and the other end is used to be inserted into the metal tube and rotatably connected to the metal tube.

[0009] Preferably: a guide groove and a turn groove are provided on the inner wall of the metal tube, the guide groove extends along the axial direction of the metal tube, one end of which extends to the top of the metal tube, and the other end is connected to the turn groove, the turn groove is coaxial with the metal tube, and the heights of the two ends are different, and a block for cooperating with the guide groove and the turn groove is provided on the outer circumferential surface of the bottom end of the metal buckle.

[0010] Preferably, the top end of the metal buckle protrudes out of the box cover, and the outer circumferential surface of the end is provided with anti-slip grooves.

[0011] Preferably: a polygonal insertion hole is provided at the axis center of the top end of the metal buckle.

[0012] The beneficial effect of the utility model is that an opening is arranged on the sealing ring, and when the box cover is connected to the box body, the box cover contacts the sealing ring, and the patch cooperates with the sealing ring to form a negative pressure sealing cavity at the opening of the sealing ring, so that a better sealing effect is formed at the connection between the box cover and the box body, so as to have high-efficiency dustproof and waterproof performance.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0020] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0021] according to Figure 1-4As shown, a P69 strong sealing junction box comprises a box cover 1 and a box body 2 with an opening, the opening end of the box body 2 is provided with a groove, a sealing ring 3 made of rubber material is provided in the groove, the sealing ring 3 is higher than the groove, and the cross section of the sealing ring 3 is set to be V-shaped, Y-shaped or U-shaped; the opening direction of the sealing ring 3 is consistent with the opening direction of the box body 2, and a patch 11 with a smooth surface is provided at the bottom of the box cover 1 corresponding to the position of the sealing ring 3. An opening is provided on the sealing ring 3, and when the box cover 1 is connected to the box body 2, the box cover 1 contacts the sealing ring 3, and the patch 11 cooperates with the sealing ring 3 to form a negative pressure sealing cavity at the opening of the sealing ring 3, so that a good sealing effect is formed at the connection between the box cover 1 and the box body 2, so as to have high efficiency dustproof and waterproof performance.

[0022] according to Figure 1-4 As shown, the box cover 1 is fixedly connected to the box body 2 by a metal buckle 5. A connection hole is provided at the open end of the box body 2, and a metal tube 4 is riveted in the connection hole. The metal buckle 5 is arranged in a columnar shape, one end of which is rotatably connected to the box cover 1, and the other end is used to be inserted into the metal tube 4 and rotatably engaged with the metal tube 4. A guide groove 41 and a turn groove 42 are provided on the inner wall of the metal tube 4. The guide groove 41 extends along the axial direction of the metal tube 4, one end of which extends to the top of the metal tube 4, and the other end is connected to the turn groove 42. The turn groove 42 is coaxial with the metal tube 4, and the two ends thereof have different heights. A clamping block for cooperating with the guide groove 41 and the turn groove 42 is provided on the outer circumferential surface of the bottom end of the metal buckle 5.

[0023] according to Figure 1-4 As shown, the top end of the metal buckle 5 protrudes out of the box cover 1, and an anti-slip pattern 51 is arranged on the outer circumferential surface of the end, and a polygonal insertion hole 52 is opened at the axis center of the top end of the metal buckle 5.
