[0002] A window wiper is a tool for cleaning windows. Its structure usually includes a handle, a connecting frame and a wiper strip. Some wiper strips need to be fixed in the connecting frame by screws. In order to ensure that the screws can pass through the connecting frame, holes need to be drilled in the connecting frame. During the drilling process of the connecting frame, there will be a slight movement, deviating from the predetermined hole position, which will affect the assembly of the window wiper and may even cause the window wiper to be unusable. For this reason, a drilling positioning jig for window wiper production is designed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , a drilling positioning jig for the production of a window wiper, including a support plate 1. A baffle 2 is provided on the top of the support plate 1. Two sides of the front surface of the baffle 2 are inserted with pull rods 3. A support plate 4, a compression spring 5, and a moving block 6 are sequentially sleeved on the outer surface of the pull rod 3. The support plate 4 abuts against the front surface of the baffle 2. An adjusting nut 7 is threadedly sleeved on the outer surface of the pull rod 3. The tail end of the pull rod 3 passes through the baffle 2 and is fixedly connected to a connecting rod 8. One end of the connecting rod 8 is fixedly connected to a clamping plate 9. By pushing the adjusting nut 7, the compression spring 5 can be contracted, and the clamping plate 9 is pushed through the pull rod 3 and the connecting rod 8. Then, the wiper strip connecting frame 14 is abutted against the back surface of the baffle 2. After loosening the adjusting nut 7, the rebounding force of the compression spring 5 pushes the moving block 6, and the connecting rod 8 is pulled through the pull rod 3, so that the clamping plate 9 is inserted into the wiper strip connecting frame 14, and the wiper strip connecting frame 14 can be positioned and supported, ensuring that the drill bit on the drilling equipment can drill the wiper strip connecting frame 14 according to the predetermined position, preventing the wiper strip connecting frame 14 from shifting during the drilling process, making the operation more stable and reliable, and thus greatly improving the drilling accuracy.

[0023] One end of the compression spring 5 abuts against the front surface of the support plate 4, and the other end of the compression spring 5 abuts against the back surface of the moving block 6. When the adjusting nut 7 is rotated counterclockwise, the adjusting nut 7 will push the moving block 6, and the moving block 6 slides on the pull rod 3. The compression spring 5 is squeezed by the moving block 6, and the compression spring 5 contracts under force; when the adjusting nut 7 is rotated clockwise, the elastic force of the compression spring 5 will push the moving block 6, and the compression spring 5 extends, and thus the elastic force of the compression spring 5 can be adjusted, further optimizing the positioning stability of the drilling positioning jig and ensuring the accuracy and precision of drilling.

[0024] A limiting groove 10 is opened in the middle of the back surface of the baffle 2. The length of the limiting groove 10 is equal to the length of the wiper strip connecting frame 14, and the wiper strip connecting frame 14 is located inside the limiting groove 10. During the drilling process of the wiper strip connecting frame 14, the wiper strip connecting frame 14 is abutted against the back surface of the baffle 2, and the wiper strip connecting frame 14 is located in the limiting groove 10, which has a limiting effect on the wiper strip connecting frame 14.

[0025] On both sides of the front of the baffle 2, there are one-word slots 11 opened. The outer surface of the pull rod 3 is slidably connected to the inner side wall of the one-word slot 11, and the outer diameter of the support plate 4 is greater than the height of the one-word slot 11. The pull rod 3 can slide left and right within the one-word slot 11. Through the connecting rod 8, the position of the clamping plate 9 can be adjusted to ensure that the clamping plate 9 can be inserted into the squeegee connecting frame 14, ensuring the stability of the squeegee connecting frame 14.

[0026] On both sides of the baffle 2, there are fixed ears 12 fixedly connected. The fixed ears 12 are fixedly connected to the top of the support plate 1. Through the fixed ears 12, the baffle 2 can be fixed to the top of the support plate 1, facilitating the installation and fixation of the baffle 2.

[0027] In other embodiments, at the four corners of the bottom of the support plate 1, there are sliders fixedly connected. The bottom of the sliders is slidably connected to a slide rail 13, and the slide rail 13 is fixedly connected to the drilling equipment. The sliders can slide within the slide rail 13, enabling the support plate 1 to move left and right, facilitating the drilling of multiple holes on the squeegee connecting frame 14.

[0028] Working principle: Push the adjusting nut 7, which can cause the compression spring 5 to contract, and push the clamping plate 9 through the pull rod 3 and the connecting rod 8;

[0029] Then, abut the squeegee connecting frame 14 against the back of the baffle 2 and make the squeegee connecting frame 14 located within the limit slot 10. Loosen the adjusting nut 7, and the rebounding force of the compression spring 5 pushes the moving block 6, pulling the connecting rod 8 through the pull rod 3, causing the clamping plate 9 to be inserted into the squeegee connecting frame 14, which can position and support the squeegee connecting frame 14, ensuring that the drill bit on the drilling equipment can drill the squeegee connecting frame 14 at a predetermined position and preventing the squeegee connecting frame 14 from shifting during the drilling process.

[0030] When the adjusting nut 7 is rotated counterclockwise, the adjusting nut 7 will push the moving block 6, and the moving block 6 slides on the pull rod 3, squeezing the compression spring 5 through the moving block 6, and the compression spring 5 contracts under force; when the adjusting nut 7 is rotated clockwise, the elastic force of the compression spring 5 will push the moving block 6, and the compression spring 5 extends, thereby enabling the adjustment of the elastic force of the compression spring 5, further optimizing the positioning stability of the drilling positioning jig and ensuring the accuracy and precision of drilling.

[0031] It should be noted that the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
