Description

Technical Field

[0001] The utility model relates to the technical field of windshield wipers, in particular to a windshield wiper which is easy to install. Background Art

[0002] Windshield wipers, also known as wipers, water paddles, wipers or windshield wipers, are devices used to scrape away raindrops and dust attached to the windshield of a vehicle to improve the driver's visibility and increase driving safety. Because of legal requirements, cars in almost all places are equipped with wipers. The rear windows of vehicles such as hatchbacks and SUVs are also equipped with wipers. In addition to cars, other means of transportation are also equipped with wipers, such as trains and trams. Some engineering machinery, such as cranes, are also equipped with wipers.

[0003] On current framed wiper blades, the end caps at both ends of the frame directly block the ends of the rubber strips installed on the steel bar, so that the rubber strips are stably placed on the steel bar for use. This structure is not easy to disassemble, making it difficult for users to replace the rubber strips by themselves after they are damaged. Usually, they need to go back to the repair shop and let the maintenance personnel use professional tools to disassemble the rubber strips before replacing them with new ones, which is inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a wiper that is easy to install.

[0005] In order to solve the above problems, the technical solution of the utility model is: a wiper that is easy to install, including a wiper body, a movable block is provided on the top of the wiper body, a connecting rod is provided at one end of the movable block, a clamping groove is provided inside the movable block near one end of the connecting rod, a spring one and a spring two are provided inside the clamping groove, the top of the spring one is fixedly connected with the clamping block, the clamping block is a Z-shaped structure, the clamping block extends to the second end of the spring away from one end of the spring, the side of the connecting rod near the second end of the spring is fixedly connected with a limiting rod, the limiting rod is provided with a limiting groove for cooperating with the clamping block away from one end of the connecting rod, the end of the connecting rod is provided with a movable groove near the spring one, the top of the movable groove is provided with a through groove, a pressure rod is provided in the movable groove, the top of the pressure rod is fixedly connected with a lever, and the lever is inserted into the through groove.

[0006] Furthermore, fixed plates are fixedly connected on both sides of the middle position of the top of the wiper body, and both sides of the movable block are rotatably connected between the two fixed plates.

[0007] Furthermore, a rotating shaft is inserted in the middle position of the clamping block, and the rotating shaft is rotatably connected to the wall of the clamping groove.

[0008] Furthermore, a spring three is fixedly connected between the pressure rod and the groove wall at the end of the movable groove, and one end of the pressure rod away from the spring three extends into the clamping groove.

[0009] Furthermore, one end of the second spring close to the limiting rod is fixedly connected with a top block.

[0010] The advantages of the utility model compared with the existing technology are: when the limit rod is inserted into the movable groove during installation, the limit rod squeezes the movable end of the clamping block, so that the clamping block leaves the two ends of the spring, and the limit rod continues to press down. When encountering the limit groove, the spring releases pressure to lift the clamping block, so that the movable end of the clamping block is clamped in the limit groove and thus limits the limit rod. During disassembly, the push rod is pushed by the push rod to squeeze the fixed end of the clamping block, so that the movable end of the clamping block is away from the limit groove, thereby separating the connecting rod from the movable block, making the overall disassembly more convenient. During installation, the pressure rod does not contact the clamping block due to the three contraction effects of the spring. BRIEF DESCRIPTION OF THE DRAWINGS
