Description

Technical Field

[0001] The utility model relates to the technical field of hole-blocking patches, in particular to an easy-to-stick PVC patch with a process hole. Background Art

[0002] During the automobile production process, some process holes need to be opened on the surface of the body sheet metal to meet the needs of production and assembly. However, these process holes are not only the entrance of water, dust and noise, but also affect the aesthetics of the body. Therefore, a hole plugging process is required during the assembly process of the automobile. The current hole plugging method is patch plugging, and some existing patches require on-site glue coating for bonding, which is a cumbersome process and inefficient. The patches with their own adhesives have unstable bonding performance, especially when the temperature is low. The adhesive solidifies, which seriously affects the bonding ability, resulting in reduced fit and easy to fall off, which is not conducive to people's use. To this end, we designed an easy-to-stick PVC patch with process holes to solve the above technical problems. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] See also Figure 1-5 In the embodiment of the present invention, an easy-to-stick process hole PVC patch includes a shell 1 and a PVC patch body 19. The shell 1 is a rectangular parallelepiped structure. A handle 2 is fixed at the left end of the bottom of the shell 1. A control button 3 is provided on the handle 2. A battery is provided in the handle 2. A slider 7 adapted to the slider 7 is slidably provided in the inner cavity of the shell 1. A long rod 8 is provided on the right side of the slider 7. A suction cup 9 for adsorbing the PVC patch body 19 is provided at the other end of the long rod 8. A push rod 4 is provided on the left side of the slider 7. The other end of the push rod 4 extends to the outside of the shell 1 and is connected to a push button 5. The push rod 4 is slidably connected to the shell 1. A through hole 10 for the PVC patch body 19 to pass through is opened on the right side of the shell 1. The shell 1 Fans 11 are symmetrically installed on the upper and lower surfaces. The air outlet end of the fan 11 is connected to the heating box 13 through a connecting pipe 12. The other side of the heating box 13 is connected to an L-shaped air pipe 14. The other end of the L-shaped air pipe 14 extends into the interior of the shell 1 and is connected to an inclined pipe 15. The other end of the inclined pipe 15 is connected to a blow hood 16. The two blow hoods 16 are symmetrically arranged up and down on the left side of the through hole 10. Positioning columns 6 are provided at the four corners of the right surface of the shell 1. The PVC patch body 19 includes a PVC layer 20. An adhesive 21 is provided on one side of the PVC layer 20, and silicone oil paper 22 is provided on the other side of the adhesive 21. The suction cup 9 abuts and adsorbs the surface of the PVC layer 20 away from the adhesive 21.

[0020] The outer sleeve of the air outlet of the blowing cover 16 is provided with a dust filter plate 17, which can filter impurities and dust in the air to ensure clean blowing. Otherwise, impurities and dust will be blown onto the PVC patch body 19 and affect the pasting performance.

[0021] The inclined tube 15 is provided with a fixed support rod 18 , the other end of which is fixedly connected to the inner cavity side wall of the shell 1 ; when there is fast-flowing gas in the inclined tube 15 , the fixed support rod 18 plays a role in fixing and supporting the inclined tube 15 .

[0022] A heating tube is provided in the heating box 13 , and the heating tube is electrically connected to the battery; the air drawn in by the blower 11 can be heated by the heating tube, thereby achieving blowing heating of the adhesive 21 .

[0023] The push button 5 is spherical, which makes it convenient for the user to hold the push button 5 to push or pull the push rod 4.

[0024] A protrusion 23 is provided in the middle of the bottom of the silicone oil paper 22 to facilitate tearing off the silicone oil paper 22. The material of the protrusion 23 can be the silicone oil paper itself or a plastic sheet.

[0025] When in use, hold the push button 5 and push the push rod 4 toward the housing 1, thereby pushing the slider 7 and the long rod 8 to the right, so that the suction cup 9 moves to the outside of the housing 1 through the opening 10, and then the suction cup 9 contacts and presses the surface of the PVC layer 20 of the patch body 19. Figure 3 As shown, the patch body 19 is adsorbed on the suction cup 9, and then the silicone oil paper 22 is torn off to expose the adhesive 21. Then, the push button 5 is pulled outward, so that the push rod 4 drives the slider 7 together with the long rod 8 to move to the left, and then the suction cup 9 together with the PVC layer 20 and the adhesive 21 are moved into the housing 1, as shown in FIG. Figure 2 As shown, at this time, the staff member holds the handle 2 with his other hand and presses the control button 3 to start the fan 11 and the heating tube. The heated gas is finally blown out through the inclined tube 15 and the blowing hood 16 and blows towards the surface of the adhesive 21 to heat it. The blowing hood 16 is provided with two upper and lower ones, and both are inclined toward the adhesive 21 to ensure that the adhesive 21 is heated evenly and improves the adhesion. After heating is completed, the fan 11 and the heating tube can be turned off by the control button 3, and then the positioning column 6 is abutted against the surface of the process hole to be pasted to ensure that the four positioning columns 6 are located at the four corners of the outer periphery of the process hole to be pasted. Then, the push button 5 is held again to push the push rod 4 in the direction of the shell 1, thereby pushing the PVC layer 20 to move outward and finally sticking it to the process hole to be pasted, completing the patch operation, and the patch is accurate. The overall device is pistol-shaped, extremely convenient to operate, easy to use, and has a good patch effect. The patch body 19 with the PVC layer 20 has the characteristics of smooth surface, heat insulation and moisture resistance, and is worthy of promotion.

[0026] It is worth noting that because this device is for patching process holes, that is, the patch is small, the area and gravity are small, so this device does not need to worry about whether the suction cup 9 can absorb the patch body 19 and whether the surface of the adhesive 21 is heated evenly.

[0027] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
