Abstract
Description
Technical Field
[0001] The utility model relates to the field of filling, in particular to a filling device for anti-corrosion glue of automobile door sills. Background Art
[0002] In the production process of automobiles, in order to prevent the oxidation of the vehicle, anti-corrosion glue is usually sprayed on the outer wall of the vehicle body; but as the vehicle is used, some sprayed parts will wear out due to long-term switching, especially the door sills. In order to ensure that the vehicle will not be corroded, a small handheld anti-corrosion glue spraying device is usually used to spray or water the worn parts. In order to connect the spray gun, the storage tank of these spraying devices usually has a small tank opening, which makes it difficult to add the anti-corrosion glue into the storage tank after preparation; in order to facilitate the pouring of the anti-corrosion glue into the storage tank, a car door sill anti-corrosion glue filling device is used to assist in filling the anti-corrosion glue.
[0003] Existing automobile door sill anti-corrosion glue filling devices usually use an extraction needle tube device to absorb the anti-corrosion glue, and by stretching the push-pull rod, the sealing gasket moves back and forth in the pipeline to absorb or push out the anti-corrosion glue, and fill the anti-corrosion glue from the batching barrel into the storage tank.
[0004] Although this reciprocating car door sill anti-corrosion glue filling device can be used for filling, the amount filled each time is small, and the glue will solidify when it is left standing for too long. Once the extraction speed cannot keep up with the solidification speed, it will affect the uniformity of the anti-corrosion glue when spraying. Utility Model Content
[0005] The technical problem to be solved by the utility model is that the existing automobile door sill anti-corrosion glue filling device has a slow single extraction, which easily causes the anti-corrosion glue to solidify.
[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a car door sill anti-corrosion glue filling device, including an extraction needle tube device, the extraction needle tube device includes a pipeline, a sealing gasket and a push-pull rod, the sealing gasket and the push-pull rod both pass through the pipeline, one side of the push-pull rod is provided with a fixing ball for fixing the sealing gasket, the fixing ball passes through the sealing gasket, one end of the side wall of the pipeline is provided with a water outlet, one side of the water outlet is provided with a corresponding connecting capillary, the connecting capillary is connected to the water outlet through a sealing ring, and one side of the pipeline is provided with a one-way valve for one-way water intake.
[0007] As an improvement, a closing column is provided on one side of the pipeline, the push-pull rod passes through the closing column, and the closing column and the one-way valve are opposite to each other.
[0008] As an improvement, the closing column and the one-way valve are both connected to the pipeline via threads, and the sealing ring is connected to the water outlet via threads.
[0009] As an improvement, the connecting capillary passes through a sealing ring, the connecting capillary is connected to the sealing ring through body contact, and the sealing ring is connected to the water outlet through a thread.
[0010] As an improvement, a limiting groove plate for limiting the position of the sealing gasket is provided inside the pipeline, and the water outlet is located between the limiting groove plate and the one-way valve.
[0011] As an improvement, a pull rod handle is provided on one side of the push-pull rod, and the pull rod handle and the fixed ball are opposite to each other.
[0012] The advantages of the utility model compared with the prior art are: the device uses the water outlet on the side wall of the pipeline so that after the extraction needle tube device absorbs the anti-corrosion glue, it does not need to be lifted and moved to the entrance of the storage tank, and the anti-corrosion glue can be continuously input into the connecting thin tube connected to the water outlet, so that the anti-corrosion glue is directly input into the storage tank through the connecting thin tube, thereby avoiding the waste of round-trip time; during the injection process, the backflow of the anti-corrosion glue is avoided by the one-way valve, so that the anti-corrosion glue can be completely injected into the storage tank.
