DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a modular wiring harness plug for automobiles includes a sealing ring 1, both ends of the sealing ring 1 are fixedly connected with a fixing ring 2, the outer wall of the fixing ring 2 on one side is rotatably connected with an outer gear ring 3, the outer wall of the outer gear ring 3 is meshingly connected with a plurality of gears 4, the inner walls of the plurality of gears 4 are fixedly connected with a rotating shaft 5 and penetrate the sealing ring 1, both ends of the plurality of rotating shafts 5 are fixedly connected with connecting plates 6, and limiting columns 7 are fixedly connected between the plurality of groups of connecting plates 6, and the outer walls of the plurality of limiting columns 7 are fixedly connected with rubber sleeves, the outer wall of the sealing ring 1 is provided with a plurality of placement grooves 8, the limiting columns 7 are all arranged in the placement grooves 8, and two groups of limiting components are arranged on the outer gear ring 3. After the sealing structure is installed in the plate hole, the sealing structure is limited by the limiting components.

[0025] In this embodiment, the limit assembly includes two rotating blocks 9, both rotating blocks 9 are fixedly connected to the outer gear ring 3, and the other ends of the two rotating blocks 9 are fixedly connected to fixed blocks 10, and the two fixed blocks 10 are threaded with bolts 11, and one end of the two bolts 11 is fixedly connected to a conical block 12;

[0026] After the installation is completed, the conical block 12 is made to contact the fixing ring 2 by rotating the bolt 11. Since one end of the conical block 12 is sharp, it can be inserted into the fixing ring 2, thereby preventing the fixing block 10 and the rotating block 9 from being limited, thereby preventing the outer gear ring 3 from rotating and affecting the fixing effect.

[0027] In this embodiment, through holes 13 are provided at both ends of the sealing ring 1, and storage grooves 14 are provided at the tops of the two through holes 13. The two storage grooves 14 are used to store polyurethane foaming agents, and the inner walls of the two storage grooves 14 are fixedly connected with films 15;

[0028] The film 15 can prevent the polyurethane foaming agent in the storage tank 14 from contacting with moisture in the outside air, thereby preventing a curing reaction from occurring. The curing reaction is a prior art in chemistry and will not be described here.

[0029] In this embodiment, one end of each of the two through holes 13 is fixedly connected with a tension spring 16, and the other end of each of the two sets of tension springs 16 is fixedly connected with a moving block 17, and the moving block 17 is slidably connected to the through hole 13;

[0030] The moving block 17 can be pulled by the tension spring 16 to prevent the moving block 17 from moving to the other side, and the moving block 17 is limited by the through hole 13 .

[0031] In this embodiment, the two moving blocks 17 are slidably connected to the lifting block 18 at one end away from each other, and the tops of the two lifting blocks 18 are fixedly connected to multiple puncture needles 19, the other ends of the two through holes 13 are fixedly connected to the triangular block 20, and the moving blocks 17 are fixedly connected to the push rod 21 at one end close to each other;

[0032] The moving block 17 is pushed to move by the push rod 21 , and when the lifting block 18 contacts the triangular block 20 , the lifting block 18 moves upward, thereby puncturing the film 15 to allow the polyurethane foaming agent in the storage tank 14 to flow out.

[0033] It should be noted that the utility model is a modular wiring harness plug for automobiles. When in use, the sealing ring 1 is first placed in the plate hole, and then the outer gear ring 3 is rotated and the multiple gears 4 are rotated at the same time, so that the rotating shaft 5 and the connecting plate 6 are rotated at the same time, so that the limiting column 7 leaves the range of the placement groove 8, and the limiting column 7 is stuck in the plate hole, and then the bolt 11 is rotated to make the conical block 12 contact the fixed ring 2, so that the fixed block 10 and the rotating block 9 can be limited, so that the outer gear ring 3 can be limited, so it can be applied to plate holes of different diameters, and the practicality of the plugging structure is improved;

[0034] After being fixed, push the push rod 21 and move the moving block 17 to one side. When the lifting block 18 contacts the triangular block 20, the lifting block 18 will move upward, so that the puncture needle 19 pierces the film 15 to make the polyurethane foaming agent in the storage groove 14 flow out and flow to the outside and inside of the sealing ring 1. When the polyurethane foaming agent contacts the moisture in the air, a curing reaction will occur. Therefore, the polyurethane foaming agent can be filled in the entire plate hole and the inside of the sealing ring 1, thereby completing the sealing of the plate hole, making the sealing structure more convenient to install and achieving the effect of waterproof and dustproof.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
