Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically a drilling positioning guide fixture for lock handle panels. Background Technology

[0002] Door locks are core hardware accessories that ensure space security and privacy. They are generally composed of lock body, lock cylinder, lock handle, panel and other accessories. They are widely used in home, office and commercial scenarios to control the opening and closing of doors and prevent unauthorized entry. The lock handle panel serves as the external decoration and support base of the door lock. It must not only coordinate with the style of the door and play an aesthetic role, but also provide a stable installation base for components such as the lock cylinder and handle. Generally, it needs to be assembled and fixed with the lock body through drilling. However, during routine maintenance and parts replacement of locks, the mounting holes on the panel often fail due to mismatched specifications or repeated disassembly and reassembly. Replacing the entire panel directly is not only costly but also wasteful of resources. The common repair method is to enlarge or re-drill the original holes. However, the re-machined holes must be perfectly aligned with the preset mounting points of the lock body. Different lock models have different hole layouts and diameter specifications. Adjusting based solely on experience can easily lead to hole misalignment, resulting in gaps after subsequent parts assembly. Therefore, a drilling positioning guide jig for lock handle panels is proposed to address the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling positioning guide fixture for lock handle panels to solve the problems mentioned in the background art.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A drilling and positioning guide fixture for a lock handle panel includes a handle panel 1, a rubber plate 2 attached to the lower part of the handle panel 1, a limit post 3 slidably disposed through the inner side of the rubber plate 2, a base assembly 6 welded to the bottom end of the limit post 3, and a guide frame assembly 7 slidably disposed on the outer side of the base assembly 6. The guide frame assembly 7 includes a sliding frame 71, a sliding groove 72 formed on the inner side of the sliding frame 71, a locking block 73 welded to one side of the sliding frame 71, and a fixing bolt 74 threadedly connected to the inner side of the locking block 73. A sliding seat 75 is slidably disposed inside the sliding groove 72. A drilling assembly 76 is installed inside the sliding seat 75. The drilling assembly 76 includes a bevel gear reducer 761. A drill bit 762 is clamped at the upper end of the bevel gear reducer 761. A first rotating rod 763 is fixedly installed on one side of the bevel gear reducer 761. A lifting rod 764 is disposed at the lower end of the drill bit 762. A screw jack 765 is rotatably disposed inside the lifting rod 764. A second rotating rod 766 is fixedly installed on one side of the screw jack 765.

[0017] As a further implementation of this solution, the limiting post 3 has a "T" shaped vertical cross section. The limiting post 3 is fixedly connected to the support plate 4. There are four limiting posts 3, which are arranged in a rectangular array at the four corners of the support plate 4. A buffer rubber ring 5 is glued to the upper end of the support plate 4. The outer side of the buffer rubber ring 5 is glued to the bottom end of the rubber plate 2. The rubber plate 2 and the support plate 4 are parallel to each other. The limiting post 3 passes through and is fixedly connected to the support plate 4, forming a stable rigid support structure. The four limiting posts 3 are arranged in a rectangular array at the four corners of the support plate 4, which effectively limits the horizontal displacement of the rubber plate 2 above the support plate 4. At the same time, the "T" shaped vertical cross section design of the limiting post 3 can prevent the rubber plate 2 from falling off along the axial direction of the limiting post 3. The rubber plate 2 is glued to the support plate 4 through the buffer rubber ring 5 to form a flexible connection. This design makes the deformation of the rubber plate 2 uniform and controllable when the handle panel 1 is pressed, which helps to increase the friction between the rubber plate 2 and the handle panel 1 and prevent slippage.

[0018] As a further implementation of this solution, the base assembly 6 includes a grooved seat 61. Limiting grooves 62 are formed on both sides of the grooved seat 61. A strip-shaped groove 63 is formed on the inner side of the grooved seat 61. A seat hole 64 is formed on the inner side of the grooved seat 61. A push rod 65 is slidably mounted inside the strip-shaped groove 63. A positioning baffle 66 is fixedly connected to one side of the push rod 65 by a spring. The limiting groove 62 has a "T" shape in its horizontal projection. The inner side of the limiting groove 62 fits against the outer side of the locking block 73. The strip-shaped groove 63 and the seat hole 64 are interconnected, providing positioning... The baffle 66 is positioned above the rubber plate 2, and the push rod 65 slides in the strip groove 63. The positioning baffle 66, which is connected by a spring, can elastically press against the edge of the handle panel 1 to achieve positioning and avoid damaging the workpiece. It can also accommodate certain dimensional tolerances. The strip groove 63 is connected to the seat hole 64 to form an open viewing channel, which makes it easy to observe the specific position of the guide frame assembly 7. The limiting slide groove 62 adopts a "T" shaped cross section and forms a tenon-and-mortise fit with the locking block 73 to better ensure the stability of the locking block 73 when sliding.

[0019] As a further implementation of this solution, the bottom surface of the sliding frame 71 is on the same horizontal plane as the bottom surface of the base assembly 6, the upper surface of the sliding frame 71 is in contact with the bottom surface of the support plate 4, one end of the fixing bolt 74 abuts against the base assembly 6, the width of the sliding groove 72 is the same as the width of the seat hole 64, the sliding seat 75 is completely set in the sliding groove 72, the housing of the bevel gear reducer 761 is fixed to the sliding seat 75 by bolts, the included angle between the first rotating rod 763 and the second rotating rod 766 and the sliding frame 71 is 90°, and both can slide in the sliding frame 71. The bottom surface of the moving frame 71 is coplanar with the base assembly 6, and the top surface is in full contact with the bottom surface of the support plate 4, which can ensure that the force is evenly distributed when the device is placed and avoid tilting. After the fixing bolt 74 is screwed into the locking block 73, its end face simultaneously abuts against the base assembly 6 to achieve locking. The sliding seat 75 is completely sunk into the sliding groove 72, and its top surface is lower than the upper surface of the sliding frame 71, which can prevent it from colliding with other components above when it slides in the sliding groove 72. The first rotating rod 763 and the second rotating rod 766 can be adjusted by sliding to make the bevel gear reducer 761 and the screw jack 765 adapt to different processing position requirements.

[0020] As a further implementation of this solution, the included angle between the central axis of drill bit 762 and handle panel 1 is 90°. The bottom end of drill bit 762 is attached to but not fixed to the upper end of lifting rod 764. The first rotating rod 763 and the second rotating rod 766 have the same lateral projection. The central axis of drill bit 762 is set perpendicular to handle panel 1 at 90°. This ensures that the cutting direction of drill bit 762 is always perpendicular to the panel surface during the grinding of hole edges, avoiding problems such as hole tilting and uneven edge grinding. This significantly improves the perpendicularity and regularity of hole processing on handle panel 1, meeting assembly accuracy requirements. The first rotating rod 763 and the second rotating rod 766 have the same lateral projection, and they are consistent in installation dimensions and operating space occupation, simplifying the process of connecting the electric drill body, eliminating the need for frequent adjustments to the adapter structure, and improving operating efficiency.

[0021] Working process: When using the device, place the handle panel 1 on the rubber plate 2, then push the push rod 65 so that it slides in the strip groove 63. After the push rod 65 moves a certain distance, the positioning baffle 66 will abut against the edge of the handle panel 1. At this time, tighten the fixing bolt 74 so that one end of the fixing bolt 74 does not abut against the base assembly 6. Move the sliding frame 71 so that the locking block 73 slides in the limiting slide groove 62. When the guide frame assembly 7 and the seat hole 64 corresponding to the hole opened in the handle panel 1 are aligned, tighten the fixing bolt 74 again so that the locking block 73 is fixed in the sliding groove 72 and no longer slides. Then press the handle panel 1 so that the handle panel 1 squeezes the rubber plate 2 and deforms, thereby increasing the friction between the handle panel 1 and the rubber plate 2 and preventing the handle panel 1 from sliding. Next, the drill body is connected to the second rotating rod 766, and the second rotating rod 766 pushes the screw jack 765 to adjust the position of the sliding seat 75 fixed to the screw jack 765, so that the drill bit 762 installed on the bevel gear reducer 761 fixed on one side of the sliding seat 75 is aligned with the hole in the handle panel 1. Then, the drill body is started, which drives the second rotating rod 766 to rotate. After being driven by the screw jack 765, the lifting rod 764 is lifted, so that the drill bit 762 passes through the hole in the handle panel 1. Then, the drill body is connected to the first rotating rod 763, and the drill body is started to drive the first rotating rod 763 to rotate. After being driven by the bevel gear reducer 761, the drill bit 762 will rotate, thereby grinding the edge of the hole in the handle panel 1.
