[0024] Embodiment 1
[0025] As Figure 1 shown:
[0026] A waterproof distribution box for an automobile includes a main body 1 of the distribution box and a distribution board 2 installed by screws.
[0027] In this embodiment: The existing device {Publication (Announcement) Number}: CN208337093U discloses a waterproof wire distributing box with knockout holes. This patent discloses a waterproof wire distributing box for automobiles proposed in this application document. The wire distributing box body 1 in this application document adopts the same technical means as those in this existing technology, and these technical means will not be elaborated one by one here. Regarding this existing body, this application makes further improvements. For details, refer to the publicly disclosed technology below; To solve the technical problems existing in this existing technology, as disclosed in the background technology above, "Although the above design improves the waterproof performance of the wire distributing box during use, and is convenient for disassembling and fixing the wire distributing box, making it more convenient for people to use, currently the waterproof wire distributing box does not have an anti-pulling function. During use, it is easy for the cable to fall off from the wire distributing board 2, making it difficult to ensure the normal operation and safety of the device, and reducing the use effect of the device." In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, an anti-pulling component 3 and an isolation component 4 are added to this application document.
[0028] It should be noted that: The accessories adopted by the wire distributing box body 1 have been disclosed in the publication number CN208337093U, and their use effects can be referred to the publication number CN208337093U (that is, the "wire distributing interface, bus interface, knockout hole, connecting shaft, cover plate, plunger, sleeve, cable connecting wire, reinforcing rib, positioning hole, sealing gasket components" disclosed in this existing technology).
[0029] Furthermore:
[0030] Such as Figures 1-4 shown:
[0031] An anti-pulling component 3 is installed inside the wire distributing box body 1. The anti-pulling component 3 includes card seats 301 arranged on both sides of the wire distributing board 2, a pressure rod 302 arranged inside the card seats 301, and adjusting bolts 304 slidably connected to both ends of the pressure rod 302. A retaining piece 305 is fixed on the surface of the adjusting bolt 304, and the adjusting bolt 304 is threadedly connected to the wire distributing box body 1.
[0032] In this embodiment: When using this waterproof wire distributing box for automobiles, first pass the cable through the wire distributing interface (not shown in the figure). By cooperating with the pressure rod 302, the wound cable is clamped inside the card seat 301. Then rotate the adjusting bolt 304, which drives the retaining piece 305 to move downward. As the retaining piece 305 moves downward, it squeezes the pressure rod 302 to move downward, and the pressure rod 302 is used to squeeze and fix the cable, thereby strengthening the connection and fixing effect of the cable, avoiding the situation where the cable falls off from the wire distributing board 2 under the condition of being pulled, and then ensuring the normal operation and safety of the device, improving the use effect of the device, and meeting the actual use requirements.
[0033] Furthermore;
[0034] In an alternative embodiment, the card holder 301 is mounted on the surface of the distribution box body 1 by screws. Fixed blocks 306 are fixed at both ends of the pressing rod 302, and a first spring 307 is fixed between the fixed blocks 306 and the distribution box body 1.
[0035] In this embodiment: Pull the pressing rod 302 upward, so that the pressing rod 302 drives the first spring 307 to stretch through the fixed blocks 306. When the pressing rod 302 is lifted to a certain height, it is convenient to install the cable, without being restricted by the card holder 301.
[0036] Furthermore;
[0037] In an alternative embodiment, a silica gel pad 303 is fixed on the surface of the pressing rod 302.
[0038] In this embodiment: Since the silica gel pad 303 is provided on the pressing rod 302, the silica gel pad 303 can buffer when the pressing rod 302 squeezes the cable, avoiding squeezing damage to the cable and further improving the use effect of the device.
[0039] Furthermore;
[0040] In an alternative embodiment, multiple groups of equally spaced silica gel strips 308 are fixed on the inclined surface of the card holder 301.
[0041] In this embodiment: Since multiple groups of silica gel strips 308 are provided on the surface of the card holder 301, the friction can be further increased, the anti-pulling effect can be improved, and at the same time, greater wear on the cable can be avoided.
[0042] Furthermore;
[0043] In an alternative embodiment, a rotating rod is rotatably connected to the upper surface of the card holder 301 through a bearing, and a spacer 309 is fixed to the top of the rotating rod.
[0044] In this embodiment: Pull the pressing rod 302 upward, so that the pressing rod 302 drives the first spring 307 to stretch through the fixed blocks 306. When the pressing rod 302 is lifted to a certain height, hook the pressing rod 302 on the top of the spacer 309 for preliminary limit locking, which is convenient for later winding and installation of the cable.
[0045] Furthermore;
[0046] In an alternative embodiment, an isolation component 4 is installed on the card seat 301. The isolation component 4 includes a plurality of groups of isolation rods 401 disposed inside the card seat 301, pressing sheets 402 fixed on the surfaces of the isolation rods 401, and threaded sleeves 403 fixed at the tops of the isolation rods 401. A threaded rod 404 is slidably connected inside the isolation rod 401, and the threaded rod 404 is threadedly connected to the threaded sleeve 403;
[0047] A sliding groove is formed on the surface of the pressing rod 302, and the pressing sheet 402 and the pressing rod 302 are slidably connected through the sliding groove. The isolation rod 401 is designed with a hollow structure.
[0048] In this embodiment: various circuit isolations can be performed through the isolation rod 401 to avoid excessive circuit entanglement, providing convenience for later disassembly, preventing it from affecting later disassembly, avoiding heat dissipation effects due to entanglement, thereby increasing the service life of the power supply and improving safety. By rotating the threaded rod 404 upward, the position locking of the isolation rod 401 is released, and by pushing the isolation rod 401, the pressing sheet 402 is driven to slide in the sliding groove, so that the position of the isolation rod 401 can be adjusted, and thus the cable can be isolated according to the actual situation.
[0049] Working principle and usage process of the present utility model: When using this waterproof wire distribution box for automobiles, first pass the cable through the wire distribution interface (not shown in the figure), and then pull the pressure lever 302 upward, so that the pressure lever 302 drives the first spring 307 to stretch through the fixed block 306. When the pressure lever 302 is lifted to a certain height, hang the pressure lever 302 on the top of the spacer 309 for preliminary limit locking, which is convenient for the later installation of the cable. Then, wind the cable around the pressure lever 302 and wrap it around once. Subsequently, install the end of the cable on the wire distribution board 2. Then, rotate the spacer 309 so that the spacer 309 releases the block on the pressure lever 302. At this time, the first spring 307 rebounds and drives the pressure lever 302 to reset. Since there are multiple groups of silica gel strips 308 on the surface of the card seat 301, it can further increase its friction force, improve the anti-pulling effect, and at the same time avoid causing excessive wear to the cable. By cooperating with the pressure lever 302, the wound cable is clamped inside the card seat 301. Then, rotate the adjusting bolt 304, which drives the retaining piece 305 to move downward. As the retaining piece 305 moves downward, it squeezes the pressure lever 302 to move downward, and the cable is squeezed and fixed by the pressure lever 302, thereby strengthening the connection and fixing effect of the cable, avoiding the situation that the cable and the wire distribution board 2 fall off under the pulling condition, and then ensuring the normal operation and safety of the device, improving the use effect of the device, and meeting the actual use requirements. Since the pressure lever 302 is designed in an arc structure and the card seat 301 is provided with an arc groove, the contact area between the pressure lever 302 and the card seat 301 can be increased, further improving the fixing effect. Since the pressure lever 302 is provided with a silica gel pad 303, the silica gel pad 303 can buffer when the pressure lever 302 squeezes the cable, avoid squeezing and damaging the cable, further improve the use effect of the device, and at the same time increase the friction force and improve the squeezing and fixing effect on the cable. When the cable is wound around the pressure lever 302, multiple lines can be isolated by the isolation rod 401, avoiding excessive line entanglement, providing convenience for later disassembly, affecting later disassembly, and avoiding affecting the heat dissipation effect due to entanglement, thereby improving the service life of the power supply, improving safety issues. By rotating the threaded rod 404 upward, the position locking of the isolation rod 401 is released, and the isolation rod 401 is pushed, driving the extrusion piece 402 to slide in the sliding groove, so that the position of the isolation rod 401 can be adjusted, and the cable can be isolated according to the actual situation.
