Detailed Implementation
[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0020] Please see Figures 1-6 Figures show the structure of the single-point lock of this utility model and its components. As shown in the figures, this utility model provides a single-point lock, the overall structure of which includes a lock assembly 1. The lock assembly 1 includes a first fixing block 11, a pulling bar 12, a lock hook fixing seat 13, a lock hook 14, a second fixing block 15, and a clamping block 16. The first fixing block 11 and the second fixing block 15 limit and fix the pulling bar 12 from the bottom and top, respectively. The lock hook 14 is fixed on the lock hook fixing seat 13. The lock hook fixing seat 13 is embedded in the groove on the back of the pulling bar 12. The clamping block 16 is disposed on the top of the second fixing block 15. The tightening screw 17 passes through the second fixing block 15, and the top surface of the tightening screw 17 abuts against the bottom surface of the clamping block 16.
[0021] The clamping block has a U-shaped notch for installing the tightening screw. Rotating the tightening screw with the hex key 20 pushes the clamping block upwards, thus clamping the block against the profile for a secure fixation. This allows for quick and easy installation of the single-point lock. The tightening screw is hidden within the actuating strip, eliminating the need for screws on the outer surface of the lock and resulting in a more aesthetically pleasing appearance.
[0022] In one possible implementation, the tail of the locking hook 14 is provided with multiple different limiting holes 141, and the extension length of the locking hook 14 is adjusted by the cooperation of the set screw 142 with the different limiting holes 141.
[0023] The hook mounting base has multiple mounting holes, and the tail of the hook has multiple different elliptical limiting holes. By aligning the limiting holes of the hook with the mounting holes on the hook mounting base and using set screws to secure the hook to the mounting base, the extension length of the hook can be adjusted through the different limiting holes. Figure 5 As shown, the length of the locking hook can be adjusted left and right according to actual requirements. The adjustment range between each hole is about 1.5mm. By setting multiple hooks, multiple extension length adjustments can be achieved.
[0024] In one possible implementation, a decorative cover 18 is provided on the toggle bar 12 relative to the position of the set screw 142.
[0025] The decorative cover allows the set screws to be hidden behind it, making the product look more aesthetically pleasing and simple.
[0026] When the length of the lock hook needs to be adjusted, first remove the decorative cover, rotate the set screw, adjust the different limit holes to achieve the appropriate extension length, and then tighten it with the set screw.
[0027] In one possible implementation, the bottom end of the lever 12 is also provided with a step 121.
[0028] This utility model's single-point lock also features a stepped design on the actuating bar. To lock, first press down the actuating bar, then push it downwards, causing the locking hook to move lower, thus achieving locking. (See also...) Figure 6 As shown. Due to the design of the steps, the toggle bar must be pressed before pushing down, effectively solving the problem of preventing the use of magnetic cards or card inserts to open the door, and effectively providing anti-theft functionality.
[0029] In one possible implementation, the single-point lock also includes a housing 19, which is used to limit and fix the lock assembly 1.
[0030] The design of the outer casing allows the entire lock assembly to be fixed and contained within it, resulting in a single-point lock with a streamlined appearance that is more aesthetically pleasing and attractive to consumers.
[0031] In one possible implementation, the housing 19 includes a panel 191 and a limiting groove 192 on the back of the panel, the locking assembly 1 is confined within the limiting groove 192, and the panel 191 has a pre-reserved slot 193 for the exposed toggle bar 12.
[0032] The outer casing 19 includes a panel 191, on the back of which a strip-shaped limiting groove 192 is provided. The entire locking assembly is limited within the strip-shaped limiting groove. Furthermore, a slot 193 is provided on the front of the panel to expose the toggle bar, allowing the toggle bar to be exposed from the slot for easy operation.
[0033] The above detailed description of the single-point lock, in conjunction with the accompanying drawings, indicates that the single-point lock of this utility model includes a lock assembly. The lock assembly includes a first fixing block, a toggle bar, a lock hook fixing seat, a lock hook, a second fixing block, and a clamping block. The first and second fixing blocks respectively limit and fix the toggle bar from the bottom and top. The lock hook is fixed to the lock hook fixing seat, which is embedded in a groove on the back of the toggle bar. The clamping block is positioned on top of the second fixing block, and a tightening screw passes through the second fixing block, with the top surface of the tightening screw abutting against the bottom surface of the clamping block. The clamping block is quickly and securely installed by pushing it with the tightening screw. Since the tightening screw is hidden within the toggle bar, the overall single-point lock has no screws on its outer surface, resulting in a more aesthetically pleasing appearance.
[0034] Furthermore, the extension length of the lock hook can be adjusted through different limiting holes to meet the needs of different usage scenarios. In addition, the toggle bar is set with steps, making it impossible to open with a magnetic card or a flat tool, which effectively prevents theft.
[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
