Description

Technical Field

[0001] This utility model relates to the field of wiper blade technology, and in particular to a wiper blade replacement tool. Background Technology

[0002] Wiper blades are the working parts of a car's windshield wipers, which come into direct contact with the windshield and scrape away rainwater, dust, and other impurities through reciprocating friction. Wiper blade replacement tools are tools used to help workers disassemble and replace wiper blades.

[0003] Existing wiper blade replacement tools typically involve manual replacement of the wiper blades. When the wiper blades are fixed to the wiper with screws or clips, they cannot be manually removed. Instead, appropriate tools are needed to remove the screws or clips, increasing replacement time and reducing efficiency.

[0004] Therefore, to address the problem of reduced replacement efficiency caused by the need to find corresponding tools to remove the screws or clips of the wiper blades, this utility model eliminates the time spent searching for corresponding tools by using screwdrivers and screwdrivers installed on the sides of the internal support plates of the two fixed housings. As needed, the screwdrivers and screwdrivers can be extended outside the fixed housing to disassemble the screws and clips, thereby improving the replacement efficiency. Utility Model Content

[0005] To overcome the problem that common rotating tool racks lack dust protection, which reduces the lifespan of tools.

[0006] The technical solution of this utility model is as follows: a wiper blade replacement tool, including a left clamp, a right clamp and a fixing shell. The right clamp is rotatably mounted on the bottom outer wall of the left clamp. The fixing shell is installed on the side outer wall of both the left clamp and the right clamp. A limiting mechanism is installed on the side of the fixing shell. A lubrication mechanism is installed on the top of the left clamp. A locking mechanism is installed on the side of the left clamp.

[0007] Preferably, the limiting mechanism includes a limiting shell, a button, a pressing post, a locking post, a support spring, a pushing block, a movable block, a support plate, and a screwdriver. Two sets of limiting shells are symmetrically provided on the outer side wall of the fixed shell, with two limiting shells in the same set. A button is slidably installed inside the limiting shell, with the protruding end of the button located above the limiting shell, and the button having an "I" shaped cross-section. A pressing post is installed on the bottom outer wall of the button. The fixed shell has a cavity inside for the movable block to be slidably installed.

[0008] Preferably, the movable block has symmetrically formed cavities on its outer side for the sliding of the locking pin, and the fixed shell has symmetrically formed cylindrical openings on its outer side for the sliding connection of the locking pin, with the cylindrical openings located directly below the limiting shell. A support spring is installed between the bottom outer wall of the locking pin and the bottom inner wall of the cavity inside the movable block. A push block is installed on the outer side of the movable block, and a rectangular groove is formed on the outer side of the fixed shell for the sliding connection of the push block. A support plate is installed on the outer side of the movable block, with a screwdriver installed on one side of the support plate and a screwdriver installed on the other side of the support plate.

[0009] Preferably, the lubrication mechanism includes a central shaft, a first drain hole, an oil reservoir, a semi-circular rubber block, a groove, an inlet, and a second drain hole. The central shaft is rotatably mounted on the inner side wall of the left clamp and the inner side wall of the right clamp. Two sets of first drain holes are symmetrically opened on the outer side wall of the central shaft, with two first drain holes in the same set. Four sets of grooves are opened at equal angles on the outer top wall of the central shaft.

[0010] Preferably, an oil reservoir is rotatably mounted on the inner side wall of the central shaft, and a second leak hole is symmetrically opened on the outer side wall of the oil reservoir. There are two second leak holes in the same group. An inlet is installed on the outer top wall of the oil reservoir, and four sets of semi-circular rubber blocks are installed at equal angles on the outer bottom wall of the oil reservoir.

[0011] Preferably, the engaging mechanism includes a mounting block, a limiting block, a limiting post, and a limiting screw. Mounting blocks are installed on the outer side walls of both the left and right clamps. The mounting blocks are side-mounted "U"-shaped structures. A limiting block is rotatably mounted on the inner side wall of one set of mounting blocks, and a limiting screw is threaded onto the outer top wall of the other set of mounting blocks. A limiting post is installed on the outer side wall of the limiting block, and the limiting screw passes through the limiting post.

[0012] The beneficial effects of this utility model are: 1. With a lubrication mechanism, lubricating oil is injected into the oil reservoir through the inlet during use. When the pliers need lubrication, the semi-circular rubber block is rotated and moved into the groove on the lower side to align the first and second drain holes. Then, the lubricating oil inside the oil reservoir leaks through the first and second drain holes to the joint connecting the left and right pliers, thus lubricating the joint of the pliers and ensuring flexibility and smoothness during use, and increasing the service life of the tool. 2. By setting a limiting mechanism, during use, the required screwdriver or screwdriver can be selected according to the fixing method of the wiper blade. After selection, press the button to push the pressing column into the inside of the fixing housing. Then push the pushing block to push the movable block forward, so that the screwdriver or screwdriver extends out of the fixing housing. At this time, the locking column moves to the position of another set of limiting housings. The support spring pops the locking column back into the cylindrical opening on the fixing housing to fix the movable block. This reduces the time needed to find specific tools, thereby reducing replacement time and improving replacement efficiency. In addition, the pliers composed of left and right pliers can clamp the rubber strip to pull out and install the rubber strip on the wiper, avoiding the deformation caused by pressing the rubber strip blade with fingers, which would affect the wiping effect and reduce the service life of the wiper blade.

Two sets of limiting shells 41 are symmetrically provided on the outer side wall of the fixed shell 3. There are two limiting shells 41 in the same set. The button 42 is slidably installed inside the limiting shell 41. The protruding end of the button 42 is located above the limiting shell 41, and the cross-section of the button 42 is an "I" shaped structure. The pressing post 43 is installed on the outer wall of the bottom end of the button 42. The fixed shell 3 has a cavity for the movable block 47 to be slidably installed inside.

[0018] The movable block 47 has symmetrically provided cavities on its outer side for the locking post 44 to slide. The fixed shell 3 has symmetrically provided cylindrical openings on its outer side for the locking post 44 to slide. The cylindrical openings are located directly below the limiting shell 41. A support spring 45 is installed between the bottom outer wall of the locking post 44 and the bottom inner wall of the cavity inside the movable block 47. A push block 46 is installed on the outer side of the movable block 47. The fixed shell 3 has a rectangular groove on its outer side for the push block 46 to slide. A support plate 48 is installed on the outer side of the movable block 47. A screwdriver 49 is installed on the outer side of one support plate 48, and a screwdriver 410 is installed on the outer side of the other support plate 48.

[0019] The lubrication mechanism 5 includes a central shaft 51, a first drain hole 52, an oil reservoir 53, a semi-circular rubber block 54, a groove 55, an inlet 56, and a second drain hole 57. The central shaft 51 is rotatably mounted on the inner side wall of the left clamp 1 and the inner side wall of the right clamp 2. Two sets of first drain holes 52 are symmetrically opened on the outer side wall of the central shaft 51, and there are two first drain holes 52 in the same set. Four sets of grooves 55 are opened at equal angles on the outer top wall of the central shaft 51.

[0020] An oil reservoir 53 is rotatably mounted on the inner side wall of the central shaft 51. A second leakage hole 57 is symmetrically opened on the outer side wall of the oil reservoir 53. There are two second leakage holes 57 in the same group. An inlet 56 is installed on the outer top wall of the oil reservoir 53. Four sets of semi-circular rubber blocks 54 are installed at equal angles on the outer bottom wall of the oil reservoir 53.

[0021] The locking mechanism 6 includes a mounting block 61, a limiting block 62, a limiting post 63, and a limiting screw 64. Mounting blocks 61 are installed on the outer side walls of the left clamp 1 and the outer side walls of the right clamp 2. The mounting blocks 61 are side-mounted "U" shaped structures. A limiting block 62 is rotatably mounted on the inner side wall of one set of mounting blocks 61, and a limiting screw 64 is threadedly mounted on the outer top wall of the other set of mounting blocks 61. A limiting post 63 is installed on the outer side wall of the limiting block 62, and the limiting screw 64 passes through the limiting post 63.

[0022] Working principle: According to Figures 1-3 As shown, when it is necessary to disassemble the rubber strip from the fixed end of the wiper, select a screwdriver 410 or a screwdriver 49 as needed. Then press the button 42 on the right limiting shell 41 on the side of the tool. This pushes the pressing post 43 downwards, pushing the locking post 44 back into the fixed shell 3. Then, push the pushing block 46, causing the movable block 47 to move forward. The movable block 47 pushes the support plate 48 to extend the tool out of the fixed shell 3. At this time, the locking post 44 moves to the position of the left limiting shell 41. The spring 45's rebound force pushes the locking post 44 back into the cylindrical opening of the fixed housing 3 to fix the movable block 47. This allows the tool to be extended to disassemble the fixed end between the rubber strip and the wiper. Then, the pliers consisting of left pliers 1 and right pliers 2 are used to open and clamp the rubber strip, pulling it out of the wiper. A new rubber strip is then reinstalled into the wiper using the pliers. This process of removing and replacing the wiper rubber strip reduces the time spent searching for tools and improves replacement efficiency.

[0023] according to Figures 4-5 As shown, when the pliers consisting of left clamp 1 and right clamp 2 are needed, the limiting screw 64 is unscrewed, and then the limiting block 62 is opened, allowing the limiting post 63 to be pulled away from the mounting block 61. This allows the left clamp 1 and right clamp 2 to be opened normally by rotation. When the left clamp 1 and right clamp 2 need to be lubricated, the oil reservoir 53 is rotated, causing the semi-circular rubber block 54 to move from one side groove 55 to the other side groove 55, so that the first drain hole 52 and the second drain hole 57 are aligned. Then, the lubricating oil inside the oil reservoir 53 flows through the first drain hole 52 and the second drain hole 57 to the joint between the left clamp 1 and right clamp 2 for lubrication, ensuring the normal flexibility and smoothness of the pliers consisting of left clamp 1 and right clamp 2, and avoiding jamming that would require more force to open the pliers. After lubrication is completed, the oil reservoir 53 is rotated again, and the semi-circular rubber block 54 continues to move to the next side groove 55, so that the first drain hole 52 and the second drain hole 57 are separated, and lubrication stops.

[0024] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
