A fixing structure of a plug-in piece and a blade arm in a water-spraying wiper blade

Abstract

This utility model discloses a fixing structure for a connector and wiper arm in a windshield washer blade, including a wiper arm and a connector. The connector has at least one flow channel inside and is provided with at least one water inlet socket and at least one water outlet socket. The water inlet socket and the water outlet socket communicate with both ends of the flow channel. The water outlet socket is inserted into at least one water inlet of the flow channel element, and the water inlet socket is connected to a water supply pipe in the windshield washer blade. The key feature is that a spring piece is provided on at least one side of the connector, and a first opening is provided on at least one side of the wiper arm corresponding to the position of the connector. During installation, the spring piece elastically deforms and locks into the first opening. This utility model, by fixing the connector to the wiper arm and then fixing it to the water inlet on the flow channel element, eliminates relative movement, improves sealing reliability, and simplifies assembly.

Description

Technical Field

[0001] This utility model relates to the field of water spray wiper blade technology, and in particular to a fixing structure for a water spray wiper blade connector and a wiper arm. Background Technology

[0002] In commercially available windshield washer fluid sprayers, the water hose is often connected to the inlet on the wiper blade mount using a connector. However, this connection often results in relative movement between the connector and the inlet, leading to lower sealing reliability and more complex assembly. Furthermore, the existing connector fixing methods are also quite complicated. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a relatively simple fixing structure for the water spray wiper blade connector and the wiper arm, which is often subject to relative movement and low sealing reliability at the connection between the existing connector and the water inlet on the fixed base.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A fixing structure for a connector and wiper arm in a windshield washer blade includes a wiper arm and a connector. The connector has at least one flow channel inside and is provided with at least one water inlet socket and at least one water outlet socket. The water inlet socket and the water outlet socket are connected to both ends of the flow channel. The water outlet socket is inserted into at least one water inlet of the flow channel element. The water inlet socket is connected to a water supply pipe in the windshield washer blade. The feature is that a spring piece is provided on at least one side of the connector, and a first opening is provided on at least one side of the wiper arm corresponding to the position of the connector. During installation, the spring piece is elastically deformed and locked in the first opening.

[0006] In a preferred embodiment of the present invention, an intermediate connecting portion is provided at the middle position of the connector, and the spring piece is provided on at least one side of the intermediate connecting portion.

[0007] In a preferred embodiment of the present invention, at least one protrusion is provided on the top surface of the intermediate connecting part, and at least one second opening is provided on the scraper arm at the position corresponding to the intermediate connecting part. During installation, the protrusion is inserted into the second opening.

[0008] By adopting the above technical solution, this utility model fixes the plug-in to the scraper arm and then fixes it to the water inlet on the flow channel element. Therefore, there is no relative movement, the sealing reliability is higher, and the assembly can be simplified. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] See Figures 1 to 6 The figure shows a fixing structure for the connector and wiper arm in a windshield washer blade, including a wiper arm 100 and a connector 200. The connector 200 has two flow channels (not shown in the figure) and is provided with two water inlet holes 210 and two water outlet plugs 220. One water inlet hole 210 and one water outlet plug 220 are connected to the two ends of one flow channel. The water outlet plug 220 is inserted into one water inlet hole of the flow channel element. The water inlet hole 210 is connected to the water supply pipe (not shown in the figure) in the windshield washer blade. In this embodiment, the flow channel element is the fixing seat 300 in the windshield washer blade.

[0017] A middle connecting part 230 is provided in the middle position of the connector 200. A spring piece 240 is provided on each side of the middle connecting part 230. An opening 111 (the aforementioned first opening) is provided on the two sides 110 of the scraper arm 100 corresponding to the position of the middle connecting part 240 of the connector 200. A protrusion 250 is provided on the top surface of the middle connecting part 240. A second opening 121 (the aforementioned second opening) is provided on the top edge 120 of the scraper arm 100 corresponding to the position of the middle connecting part 210. During installation, the spring piece 240 is elastically deformed and locked in the corresponding opening 111, and the protrusion 250 is pushed into the opening 121. By fixing the connector to the scraper arm and then fixing it to the water inlet on the flow channel element, there is no relative movement, the sealing reliability is higher, and the assembly can be simplified.
