Description

Technical Field

[0001] This utility model relates to the field of door and window lock installation device, specifically to a convenient device for installing door and window locks. Background Technology

[0002] In the field of door and window lock installation, while existing installation methods and tools can meet the needs to a certain extent, they still face many problems and challenges. Currently, the commonly used hole positioning templates in door and window lock installation are usually made of metal or high-hardness engineering plastics. They have standard holes designed strictly according to the lock dimensions, such as lock cylinder holes, screw holes, and handle holes. In use, the template is placed firmly against the correct position on the door or window edge, temporarily fixed with clamps or screws, and then drilled directly through the guide holes on the template with an electric drill. This template solves the most difficult "positioning" problem, ensuring that all holes are absolutely concentric, precisely positioned, and extremely accurate. It is a one-time molding process, eliminating the need for repeated measurements and markings, thus preventing errors and making it a highly efficient method for installing door lock sets.

[0003] However, the template itself has inherent rigidity and fixing defects. Some inexpensive or poorly made templates, such as those made of thin aluminum alloy or plastic, may bend or deform elastically when subjected to electric drills and downward pressure. This can cause slight displacement of the template's guide hole during the drill bit's penetration of the door, resulting in a deviation between the actual drilled hole and the intended position, or a non-perpendicular hole, leading to difficulties or even failure in lock installation.

[0004] Meanwhile, the template is usually fixed to the door edge by clamps. If the clamping force is insufficient, the clamping point is not properly positioned, or the door edge itself is uneven, the template will shake or shift during drilling, causing the hole position to drift. Especially when drilling large-diameter holes, the friction between the drill bit and the template is very high, which can easily cause an unstable template to move.

[0005] In addition, after repeated use, the guide holes of the metal template will be worn down by the friction of the drill bit, resulting in larger and larger hole diameters. The gap between the guide hole and the drill bit will increase, reducing the guiding accuracy. The position and verticality of the drilled hole will also decrease. Therefore, it is necessary to quickly replace the worn guide holes. However, most of the guide holes in the existing templates are directly drilled on the template. After wear, it is not convenient to replace individual guide holes. In most cases, it is necessary to replace the entire template. Utility Model Content

[0006] To address the aforementioned issues of insufficient template rigidity, insecure fixing, and inconvenient replacement of worn guide holes, which severely affect the accuracy and verticality of the holes and consequently the installation quality and smoothness of the locks, this utility model provides a convenient device for installing door and window locks.

[0007] A convenient device for installing door and window locks includes a hole-opening template with several independent self-locking clamps fixedly mounted on it. Several guide holes of varying sizes are threaded through the template, each with a threaded guide sleeve whose inner diameter precisely matches the size of a commonly used drill shank. Several grid-like reinforcing ribs are fixedly mounted on the back of the template. Each self-locking clamp includes a support plate fixedly mounted on the template, with a worm gear rotatably mounted on the support plate. The worm gear is meshed with a worm wheel, and a nut is fixedly mounted at the center of the worm wheel. The nut meshes with a lead screw, and the end of the lead screw is connected to a V-shaped chuck via a universal joint. The V-shaped chuck can clamp the door or window.

[0008] More preferably, each guide hole has an internal thread on its inner wall, a flange is fixedly provided at the top of the guide sleeve for limiting and providing a wrench holder, and an external thread is provided at the tail end of the guide sleeve. The internal and external threads are compatible with each other, and the guide sleeve is made of high carbon steel.

[0009] More preferably, the perforation template is made of steel plate with high rigidity and wear resistance, and its surface is nickel-plated for rust prevention. The thickness of the perforation template is greater than 8mm, and the number of guide holes is several, with different inner diameters.

[0010] More preferably, there are three self-locking clamps arranged in a triangular pattern. The support plate is fixedly installed on the side of the opening template away from the door and window. The support plate is L-shaped. A receiving groove is fixedly installed on the end of the support plate away from the opening template. The worm gear is rotatably installed inside the receiving groove, and one end of the worm gear passes through the receiving groove and is fixedly installed with a crank handle.

[0011] More preferably, a through groove is provided on both sides of the receiving groove, a lead screw is rotatably provided in the through groove, a worm gear is provided inside the receiving groove, and a replaceable protective gasket is inlaid on the opposite side of the V-shaped chuck. The protective gasket is made of polyurethane.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: The steel template with reinforcing ribs is made of carbon steel and undergoes surface rust prevention treatment. The reasonable reinforcing rib structure design greatly improves the rigidity and stability of the template. This allows the template to effectively resist deformation caused by the electric drill and downward pressure during drilling, ensuring that the drill bit drills in the predetermined position and perpendicularity, thus greatly improving drilling accuracy. Simultaneously, the design of quickly replaceable guide sleeves solves the problem of wear and expansion of the guide hole, allowing the template to maintain high precision even after multiple uses, extending its service life and improving its efficiency.

[0013] The triangular self-locking clamp design also makes a significant contribution to technological advancement, ensuring that the template is evenly stressed on the door edge, preventing rotation or warping. The worm gear's self-locking function allows the clamp to quickly and securely fix the template, avoiding template displacement caused by clamp loosening. The V-shaped opening of the chuck and the replaceable pad design improve the clamp's versatility and stability, protect the door's appearance, and provide sufficient friction to ensure the template does not wobble during drilling.

The following will refer to the accompanying drawings. Figures 1-5 The present invention will be described in detail with reference to the embodiments.

[0025] A convenient device for installing door and window locks includes a perforated template 1. The perforated template 1 is made of steel plate with high rigidity and wear resistance, and its surface is blackened to form a dense oxide film or nickel-plated for rust prevention, thereby extending the service life of the template.

[0026] Several grid-shaped reinforcing ribs 5 are fixedly provided on the back of the perforation template 1. The grid-shaped reinforcing ribs 5 provide support in multiple directions, so that the perforation template 1 can remain stable when subjected to forces in different directions. The reinforcing ribs 5 are reasonably arranged according to the stress characteristics of the perforation template 1, thereby enhancing the strength of the perforation template 1 in specific directions.

[0027] First, inspect the surface treatment of the opening template 1 with reinforcing ribs 5 to ensure that the blackening or nickel plating anti-rust layer on its surface is intact. Check whether the replaceable high carbon steel guide sleeve 4 on the opening template 1 is installed correctly and whether its inner diameter matches the commonly used drill shank size. Prepare the self-locking clamp 2 and check whether the V-shaped opening of the V-clamp 12 and the embedded hard nylon or polyurethane pad are intact.

[0028] The thickness of the drilling template 1 is greater than 8mm, providing basic rigidity for the template. The thicker body can better resist external forces and reduce deformation during the drilling process. Several independent self-locking clamps 2 are fixedly installed on the drilling template 1. There are three self-locking clamps 2, arranged in a triangular pattern.

[0029] Each self-locking clamp 2 includes a support plate 6 fixedly mounted on the perforation template 1. The support plate 6 is fixedly mounted on the side of the perforation template 1 away from the door and window. The support plate 6 has an L-shaped structure. A worm gear 7 is rotatably mounted on the support plate 6. The worm gear 7 is meshed with a worm wheel 8. A nut 9 is fixedly mounted at the center of the worm wheel 8. The nut 9 is meshed with a lead screw 10. The end of the lead screw 10 is connected to a V-shaped chuck 12 through a universal joint 11. The V-shaped chuck 12 can clamp the door and window. A receiving groove 16 is fixedly mounted on the end of the support plate 6 away from the perforation template 1. The worm gear 7 is rotatably mounted inside the receiving groove 16, and one end of the worm gear 7 passes through the receiving groove 16 and is fixedly mounted with a crank handle 17.

[0030] Place the opening template 1 firmly against the correct position on the door edge, determining its position according to the lock installation requirements. Secure the opening template 1 using the three-point self-locking clamps 2. Following a triangular layout, secure the three independent self-locking clamps 2 sequentially, ensuring the opening template 1 is evenly stressed on the door edge and will not rotate or tilt. During the fixing process, carefully observe whether the V-shaped opening of the V-shaped clamp 12 adaptively grips the door edge, and whether the rigid nylon or polyurethane pad is in full contact with the door edge, providing sufficient friction.

[0031] Crank handle 17 to rotate worm 7, which in turn rotates worm wheel 8. Since nut 9 is fixedly installed at the center of worm wheel 8 and is engaged with lead screw 10, the rotation of worm wheel 8 causes lead screw 10 to move closer to or away from the door or window.

[0032] Through slots 18 are provided on both sides of the receiving groove 16. A lead screw 10 is rotatably installed in the through slot 18. A worm gear 8 is installed inside the receiving groove 16. A replaceable protective gasket 19 is inlaid on the opposite side of the V-shaped chuck 12. The protective gasket 19 is made of polyurethane.

[0033] The template is positioned precisely against the door or window edge, according to the lock's size and installation location. Then, it is secured using the self-locking clamp 2. The lead screw 10 approaches the door or window edge, causing the V-shaped clamp 12 to quickly approach the edge. The worm gear 7 is then rotated to finally lock the opening template 1. Due to the use of three independent self-locking clamps 2 arranged in a triangular pattern, the opening template 1 is evenly stressed on the door or window edge, preventing shaking or displacement.

[0034] The perforation template 1 has several guide holes 3 of different sizes, and the inner diameters of the guide holes 3 are not uniform. Each guide hole 3 is threadedly connected to a guide sleeve 4. The inner diameter of the guide sleeve 4 is precisely matched with the size of a commonly used drill shank. Each guide hole 3 has an internal thread 13 on its inner wall. The top of the guide sleeve 4 is fixedly provided with a flange edge 14 for limiting and providing a wrench holder. The tail end of the guide sleeve 4 is provided with an external thread 15. The internal thread 13 and the external thread 15 are mutually compatible. The guide sleeve 4 is made of high carbon steel.

[0035] Select a suitable step drill and align the drill bit with the guide hole on the hole-opening template 1. Start the drill and begin drilling. Due to the high-precision positioning and stable fixation of the hole-opening template 1, the drill bit can accurately drill according to the predetermined position and size during the drilling process. During drilling, carefully observe the fit between the drill bit and the guide sleeve 4 in the hole-opening template 1 to ensure the perpendicularity and accuracy of the drilling. If you need to drill holes of different sizes, there is no need to change the drill bit; simply use the different steps of the step drill for drilling.

[0036] After drilling is completed, check whether the position and size of the drilled hole meet the requirements. If a slight deviation in the hole position or the hole diameter does not meet the requirements, fine-tuning can be made according to the actual situation. If the guide sleeve 4 is worn and the inner diameter of the guide sleeve 4 is found to have increased significantly, the flange edge 14 can be rotated with a wrench to rotate the external thread 15 at the tail end of the guide sleeve 4 and separate it from the internal thread 13 on the inner wall of the guide hole 3, so that the guide sleeve 4 can be removed from the guide hole 3 and a new guide sleeve 4 can be replaced.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
