Description

Technical Field

[0001] The present invention belongs to the technical field of repair devices, and particularly relates to a windshield wiper repairer. Background Art

[0002] For vehicle parts, the windshield wiper is a commonly used and easily worn part. The main component of the windshield wiper is the wiper rubber strip; the wiper rubber strip is made of rubber and has a certain flexibility, which is convenient for brushing back and forth on the window glass to clean the water on the glass and clear the line of sight for the driver. During the use of the wiper rubber strip, the scraping surface of the rubber strip is prone to wear or damage, resulting in a deterioration of the scraping effect of the windshield wiper. The damage to the scraping surface of most wiper rubber strips is only the damage to the tip of the scraping surface, and the overall structure of the wiper rubber strip is still intact and can be recycled. Replacing the entire windshield wiper due to partial damage to the scraping surface causes great waste.

[0003] The invention with the application number CN202022247550.7 discloses a windshield wiper repairer. The disadvantages of this windshield wiper repairer are as follows: (1) The cutter of the repairer cannot be adjusted, resulting in the inability to adjust the thickness of the scraping surface removed from the wiper rubber strip when repairing through this repairer, thus leading to the situation of removing too much or too little of the scraping surface. When too much of the scraping surface is removed, the number of repair times of the wiper rubber strip is reduced; when too little of the scraping surface is removed, the damaged part of the wiper rubber strip cannot be completely removed, and multiple repairs are required; (2) During the repair process, this device does not have the function of positioning and guiding multiple wiper rubber strips, which easily leads to an uneven scraping surface of the repaired wiper rubber strip.

Detailed implementation manners

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Currently, the windshield wiper rubber strip 5 on the market includes a main body 5-1 and a wiping surface 5-2 connected to the column body 5-1. The wiping surface 5-1 is used for wiping the windshield, and grooves 5-3 are provided on both sides of the main body 5-1 of the common windshield wiper rubber strip. When this repair tool repairs the windshield wiper rubber strip, the windshield wiper rubber strip 5 is guided through the grooves 5-3, thereby improving the repair accuracy of the windshield wiper rubber strip.

[0030] A windshield wiper repair tool includes: a windshield wiper limiting member 1, a tool holder 2, a cutting knife 3, and a repair tool housing 4. The cutting knife 3 is used to remove the damaged wiping surface of the windshield wiper rubber strip. The tool holder 2 is used to install the cutting knife 3. The repair tool housing 4 is used to install the tool holder 2 and the windshield wiper limiting member 1. The tool holder 2 can be adjusted in position relative to the repair tool housing 4, thereby changing the relative height of the tool holder 2. The windshield wiper limiting member 1 can rotate relative to the repair tool housing 4. By connecting the windshield wiper limiting member 1 with the groove 5-3 of the windshield wiper rubber strip, the windshield wiper rubber strip during the repair process is fixed and guided.

[0031] The repair tool housing 4 includes a first housing 4-5 and a second housing 4-6 that are spliced together. The structures of the first housing 4-5 and the second housing 4-6 are the same and are symmetrically arranged. An adjusting channel for the tool holder 2 to translate is formed between the first housing 4-5 and the second housing 4-6, which is convenient for adjusting the position of the tool holder 2.

[0032] A guide plate 4-2 is provided at the top of the first housing 4-5 and the second housing 4-6. The guide plate 4-2 is arranged obliquely relative to the bottom surface of the repairer housing 4. The tool holder 2 is slidably mounted on the guide plate 4-2. When the tool holder 2 slides on the guide plate 4-2, the bottom surface of the tool holder 2 relative to the repairer housing 4 changes. In this embodiment, the wiper strip is fixed to the bottom of the repairer housing 4. Therefore, the removal amount of the wiper strip by the cutting tool 3 also changes correspondingly during the adjustment of the tool holder 2.

[0033] An adjustment cavity 4-1 is provided at the top of the first housing 4-5 and the second housing 4-6. The guide plate 4-2 is fixedly connected or fixedly installed in the adjustment cavity 4-1. Through the setting of the adjustment cavity 4-1, it is prevented that the limit plate 2-5 of the tool holder 2 interferes with the first housing 4-5 and the second housing 4-6.

[0034] The adjustment channel includes a guiding portion 4-7 and an adjusting portion 4-8. The guiding portion 4-7 is arranged below the adjustment cavity 4-1, and the adjusting portion 4-8 is connected below the guiding portion 4-7. The guiding portion 4-7 is used to guide the movement of the tool holder 2, and the cutting tool 3 on the tool holder 2 performs up and down height adjustment in the adjusting portion 4-8.

[0035] The tool holder 2 includes a sliding groove portion 2-1, a tool mounting portion 2-2, and a connecting portion 2-3 for connecting the sliding groove portion 2-1 and the tool mounting portion 2-2. The sliding groove portion 2-1 is slidably connected to the guide plate 4-2, so that the tool holder 2 slides on the repairer housing 4. The connecting portion 2-3 is slidably mounted in the guiding portion 4-7, which is convenient for guiding the movement of the tool holder 2, ensuring the movement stability of the tool holder 2, thereby improving the cutting accuracy of the cutting tool 3. The tool mounting portion 2-2 is arranged in the adjusting portion 4-8. The sliding groove portion 2-1 and the guide plate 4-2 cooperate to adjust the height of the tool mounting portion 2-2 in the adjusting portion 4-8, thereby adjusting the height of the cutting tool 3 mounted on the tool mounting portion 2-2.

[0036] The sliding groove portion 2-1 includes an adjusting plate 2-4 and a limit plate 2-5 arranged in parallel. A sliding groove 2-6 is formed between the adjusting plate 2-4 and the limit plate 2-5, and the sliding groove 2-6 is slidably connected to the guide plate 4-2.

[0037] In this embodiment, the length and width of the adjusting plate 2-4 are both greater than the length and width of the limit plate 2-5. When cutting the wiper strip, the tool holder 2 will have a slight inclination (which can be ignored). The end portions of the adjusting plate 2-4 and the limit plate 2-5 abut against the upper and lower end faces of the guide plate 4-2, forming a lever structure. To prevent the tool holder 2 from slipping during the operation of the cutting tool 3, the lower end face or the upper end face of the guide plate 4-2 is a rough surface, and the tool holder 2 is prevented from slipping by increasing the friction, realizing stepless adjustment of the tool holder 2.

[0038] A cutting groove 2-8 is provided on the lower end surface of the tool mounting part 2-2, and the cutting knife 3 is horizontally placed at the lower end of the cutting groove 2-8. To facilitate the wiping surface of the wiper rubber strip to extend into the cutting groove 2-8, an opening groove 4-3 adapted to the cutting knife 3 is provided at the bottom of the repairer housing 4. The opening groove 4-3 and the cutting groove 2-8 are located on the same straight line. The part of the wiper rubber strip to be repaired extends into the cutting groove 2-8. Through the setting of the opening groove 4-3, it is convenient to provide a certain guiding effect for the movement of the wiper rubber strip.

[0039] The wiper limiting member 1 is provided with a guiding and limiting groove 1-1 for guiding the wiper rubber strip. The guiding and limiting groove 1-1 clamps and guides the wiper rubber strip through the groove 5-3. The guiding and limiting groove 1-1 is adapted to the cutting knife 3, that is, the guiding and limiting groove 1-1, the opening groove 4-3, and the cutting groove 2-8 are located on the same straight line.

[0040] In this embodiment, the wiper limiting member 1 includes a pair of symmetrically arranged positioning hooks 1-2. The two ends of the positioning hook 1-2 are provided with rotating shafts 1-4. The rotating shafts 1-4 at both ends are rotatably connected to the two ends of the first housing 4-5 and the second housing 4-6. The wiper rubber strip is clamped by the rotating positioning hook 1-2.

[0041] To facilitate the positioning hook 1-2 to clamp the wiper rubber strip more stably and efficiently and provide a certain guiding effect for the movement of the wiper rubber strip, a guiding strip 1-3 is provided at the end of the positioning hook 1-2. When the two side positioning hooks 1-2 are joined together, a guiding and limiting groove 1-1 is formed between the adjacent guiding strips 1-3. Moreover, the guiding strip 1-3 is inserted into the groove 5-3 of the wiper rubber strip. The guiding strip 1-3 provides a certain guiding effect for the movement of the groove 5-3 to ensure the cutting accuracy of the cutting knife 3.

[0042] To facilitate the fixation of the positioning hook 1-2 during the repair of the wiper rubber strip, a buckle 1-5 is provided on the positioning hook 1-2, and a clamping groove 4-4 is provided on the lower end surface of the repairer housing 4. During the repair of the rubber strip, the buckle 1-5 is snapped into the clamping groove 4-4. After the repair of the rubber strip is completed, the buckle 1-5 is separated from the clamping groove 4-4.

[0043] In this embodiment, the cutting knife 3 adopts a double-sided blade structure. By setting the cutting knife 3 with a double-sided blade structure, the wiper rubber strip can be repaired regardless of the moving direction in the cutting groove 2-8.

[0044] The repair steps of this wiper repairer are as follows.

[0045] (1) Open the positioning hooks 1-2 on both sides;

[0046] (2) Extend the wiping surface of the wiper rubber strip into the cutting groove 2-8;
