[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a wire harness box, such as Figure 1 , Figure 2 and Figure 5 As shown, the device includes a lower housing 1, an upper housing 2 on top of the lower housing 1, wire harness grooves 3 on both the lower housing 1 and the upper housing 2, several mounting grooves 10 on both sides of the upper housing 2, several limiting frames 4 fixedly connected to both sides of the upper housing 2, a first sliding groove 5 inside the limiting frame 4, a mounting shell 11 fixedly connected inside the mounting groove 10, a second sliding groove 12 inside the mounting shell 11, a closing mechanism inside the first sliding groove 5, and a fixing mechanism inside the second sliding groove 12.

[0032] The sealing mechanism includes a sealing plate 6, which is slidably connected inside the first slide groove 5. A slide rod 7 is fixedly connected inside the first slide groove 5. A slider 8 is slidably connected to the side surface of the slide rod 7. One side of the slider 8 is fixedly connected to one side of the sealing plate 6. A first spring 9 is sleeved on the side surface of the slide rod 7. The top end of the first spring 9 is fixedly connected to the bottom of the slider 8, and the bottom end of the first spring 9 is fixedly connected to the bottom inner wall of the first slide groove 5.

[0033] The number of limit frames 4 corresponds to the number of mounting slots 10. A toggle block is fixedly connected to one side of the sealing plate 6. A connecting plate 20 is provided inside the lower housing 1. Several wiring terminal bodies 21 are provided on the connecting plate 20.

[0034] Both sides of the lower housing 1 are fixedly connected with abutment strips 25, and the top of the abutment strips 25 fits against the bottom of the limiting frame 4.

[0035] When using this wire harness box, the wire harness needs to be connected to the terminal block 21, and then the connecting plate 20 is installed inside the lower housing 1. After installation, the wire harness needs to be adjusted into the wire harness groove 3, and then the upper housing 2 can be fastened onto the lower housing 1. After the two are fastened together, the limiting frame 4 is exactly in contact with the abutment strip 25. The abutment strip 25 can effectively improve the aesthetics of the wire harness box. At the same time, the wire harness grooves 3 on both the upper housing 2 and the lower housing 1 are located inside the limiting frame 4, and the sealing plate 6 can slide inside the limiting frame 4. When the wire harness slot 3 is in use, the first spring 9 can always apply force to the sealing plate 6 through the slider 8, so that the sealing plate 6 is stably held at the top of the first slide groove 5, thereby keeping the wire harness slot 3 in the open state. When the wire harness slot 3 is idle, the corresponding sealing plate 6 can be pulled down by the toggle block. After the sealing plate 6 moves to the bottom of the first slide groove 5, the fixing mechanism will fix it, thereby closing the wire harness slot 3 and reducing the possibility of dust and insects entering the upper housing 2 and lower housing 1 through the wire harness slot 3 and adhering to the terminal body 21.

[0036] Furthermore, in order to improve the stability of the sealing plate 6 when enclosing the wire harness groove 3, such as Figure 3 , Figure 4 and Figure 6 As shown, the fixing mechanism includes a locking block 13, which is slidably connected inside the second slide groove 12. A telescopic rod 15 is fixedly connected to one side of the inner wall of the second slide groove 12. The movable end of the telescopic rod 15 is fixedly connected to one end of the locking block 13, and the end of the locking block 13 away from the telescopic rod 15 extends to the outside of the mounting shell 11.

[0037] A second spring 16 is fitted on the side surface of the telescopic rod 15. One end of the second spring 16 is fixedly connected to the inner wall of the second slide groove 12, and the other end of the second spring 16 is fixedly connected to the end of the locking block 13 near the telescopic rod 15.

[0038] The fixing mechanism also includes a pressing block 17, which is slidably connected inside the second slide groove 12. The top of the pressing block 17 extends to the outside of the mounting shell 11, and a third spring 19 is fixedly connected to the bottom of the pressing block 17. The bottom end of the third spring 19 is fixedly connected to the bottom inner wall of the second slide groove 12.

[0039] A pressing block 18 is fixedly connected to the bottom of the pressing block 17, and a traction block 14 is fixedly connected to one side of the locking block 13. One side of the pressing block 18 and one side of the traction block 14 are in contact with each other.

[0040] In the initial state, the sealing plate 6 is located at the top of the first slide groove 5. The side of the sealing plate 6 away from the lever is in contact with the end of the locking block 13 away from the telescopic rod 15. The locking block 13 retracts inside the second slide groove 12, and the second spring 16 is in a compressed state. When the sealing plate 6 moves to the bottom of the first slide groove 5 to close the wire harness groove 3, the end of the locking block 13 away from the telescopic rod 15 will separate from the side of the sealing plate 6 away from the lever. Then the second spring 16 will release the pressure and push the locking block 13 to extend to the outside of the mounting shell 11. At this time, the bottom of the locking block 13 will abut against the top of the sealing plate 6, thereby restricting the sealing plate 6 and improving the stability of the sealing plate 6 when closing the wire harness groove 3. In addition, the sealing plate 6 When the closed wire harness groove 3 is lowered, the slider 8 will also move down. When the slider 8 moves down, it can compress the first spring 9. During the period when the sealing plate 6 closes the wire harness groove 3, the first spring 9 will always remain in a compressed state. When the closed wire harness groove 3 needs to be used, the pressing block 17 can be pressed. When the pressing block 17 moves down, it can drive the squeezing block 18 to move down. The inclined surface of the squeezing block 18 contacts the inclined surface of the traction block 14. When the squeezing block 18 moves down, the traction block 14 will drive the locking block 13 to retract inside the second slide groove 12. At this time, the sealing plate 6 loses its restriction. At the same time, the first spring 9 can release the pressure instantly and drive the sealing plate 6 to move up through the slider 8, thereby opening the closed wire harness groove 3.

[0041] Furthermore, in order to improve the stability of the connecting plate 20, such as Figure 1 and Figure 2 As shown, a connecting seat 22 is fixedly connected to the bottom inner wall of the lower housing 1. The bottom of the connecting plate 20 fits against the top of the connecting seat 22. Both the connecting plate 20 and the connecting seat 22 have a first fixing hole.

[0042] When the connecting plate 20 is installed inside the lower housing 1, it needs to be aligned with the first fixing hole on the connecting seat 22, and then bolted into the first fixing hole, which effectively improves the stability of the connecting plate 20 and facilitates subsequent disassembly.

[0043] In order to improve the stability of the lower shell 1 and the upper shell 2 after they are fastened together, such as Figure 1 and Figure 2 As shown, a sealing strip 24 is fixedly connected to the top of the lower housing 1, and a sealing groove is provided at the bottom of the upper housing 2. The top of the lower housing 1 fits into the bottom of the upper housing 2, and the sealing strip 24 is inserted into the inside of the sealing groove.

[0044] Connecting posts 23 are fixedly connected to the four corners of the lower housing 1. A second fixing hole is provided at the top of each connecting post 23. The upper housing 2 also has the same second fixing hole at each of its four top corners. When the lower housing 1 and upper housing 2 are fastened together, the second fixing hole on the upper housing 2 aligns perfectly with the second fixing hole on the connecting post 23. Bolts can then be screwed into the second fixing holes, effectively improving the stability of the lower housing 1 and upper housing 2 when fastened together. Furthermore, when the lower housing 1 and upper housing 2 are fastened together, the sealing strip 24 enters the sealing groove, effectively improving the waterproofness of the wiring harness box.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
