Description
Technical Field
[0001] This invention relates to a flat door lock, specifically an outdoor mechanical quick-install lock. Background Technology
[0002] Currently, the installation structure of flat locks used in the industry generally adopts a pressure plate or cover plate fixing method. That is, the pressure plate or cover plate is fixed by one or more screws. By turning the screw threads with a screwdriver, the fixing plate is tightened, which fixes the door lock to the door panel. The above installation is relatively inconvenient. To address this, Chinese patent application number 201910238379.2, publication date 2019.07.12, utility model title "Quick Installation Flat Lock" is disclosed. This flat lock mainly achieves quick installation through the fixing blocks with internal locking plates symmetrically arranged at the bottom of the base, and the springs between the fixing blocks and the internal locking plates. However, the stability of the above product and similar products is poor. The force on both sides of the locking plates is limited, and they can be easily forced open by external force. In addition, the bottom of the base inside the cabinet door is prone to dust entering the fixing blocks, causing blockage and affecting the normal operation of the locking plates. Summary of the Invention
[0003] To overcome the aforementioned shortcomings, the purpose of this invention is to provide an outdoor mechanical quick-release lock that addresses the technical problems of existing similar products, such as poor structural design leading to instability, low stress resistance, easy removal of the lock body by external force, and easy entry of dust into the lock body, affecting normal use. This objective is achieved through the following technical solution.
[0004] An outdoor mechanical quick-release lock has a quick-release mechanism at one end of the base on one side of the pivot shaft. The quick-release mechanism includes a first latch block and a second latch block symmetrically arranged on both sides, and a beveled latch block between the first latch block and the second latch block, and a spring for resetting the beveled latch block. The first latch block, the second latch block, and the beveled latch block are fixedly and limited in the head block groove at the bottom of the base by a head cover plate. One end of the first latch block, the second latch block, and the beveled latch block extends out of the mounting edge at the bottom of the base, thereby limiting the base from sliding out of the door panel mounting hole. The key structural design features are that the first and second locking tongue blocks are L-shaped, and the bottom and top of the oblique tongue block are provided with an upper guide groove and a lower guide groove that are intersecting and obliquely arranged. The first and second locking tongue blocks are respectively provided with an inwardly protruding first guide rib and a second guide rib at the end facing the oblique tongue block. When the first locking tongue block is inserted into the bottom head block groove of the base from the bottom of the oblique tongue block, the first guide rib of the first locking tongue block is inserted into the lower guide groove of the oblique tongue block. When the second locking tongue block is inserted into the bottom head block groove of the base from the top of the oblique tongue block, the second guide rib of the second locking tongue block is inserted into the upper guide groove of the oblique tongue block. The positioning post on one side of the bottom head block groove of the base and / or one side of the head cover plate is inserted into the positioning sliding hole of the oblique tongue block. The other end of the oblique tongue block in the bottom head block groove of the base is abutted against the inner wall of the bottom head block groove of the base or the outer diameter of the base at the pivot point by a spring. This quick-install lock improves upon the existing two-point fast-installation method by replacing it with a three-point fast-installation method. It also modifies the locking plate structure into a block-shaped latch structure, enhancing stability, and transforms the open sliding hole structure into a closed structure, further improving stability. Furthermore, the quick-install lock retracts the latch blocks on both sides by pressing the angled latch block on the head, thus achieving quick disassembly.
[0005] One end of the first locking tongue block, the second locking tongue block, and the beveled tongue block is respectively inclined towards the mounting hole of the base to the side of the door panel, and the length of the inclined side is greater than the length of the symmetrical inclined side. This facilitates the first locking tongue block, the second locking tongue block, and the beveled tongue block to be fastened to the mounting hole of the door panel and then fixed in place.
[0006] The bottom corners of the head cover are respectively provided with L-shaped snap-fit posts, which are interference-fitted to the mounting ribs protruding from the outer diameter of the head block groove at the bottom of the base. The above is a specific structural embodiment of fixing the head cover to the bottom of the base, which can also be fixed to the bottom of the base by screws or other means.
[0007] The height of the head cover plate of the quick-installation mechanism is lower than the height of the orifice at the bottom of the base where the rotating shaft protrudes. This structure prevents the head cover plate from affecting the steel bolts installed at the protruding part of the rotating shaft. The head cover plate can also adopt a beveled or grooved structure to facilitate the use of steel bolts.
[0008] The base at the other end of the axis of rotation is provided with a quick-release cover plate or another quick-release mechanism. The other end of the base bottom is thus fixed by the quick-release cover plate or the other quick-release mechanism. The specific structure of the quick-release cover plate is as follows.
[0009] The quick-release cover plate extends beyond the mounting edges of the base on both sides, and / or the quick-release cover plate at the other end of the base has a snap hook extending beyond the mounting edge of the base. This structure facilitates the quick-release lock's base to be quickly inserted into the mounting hole of the door panel via the snap hook of the quick-release cover plate at one end, and then quickly installed into the mounting hole of the door panel via the quick-release mechanism at the other end.
[0010] The quick-release cover plate is aligned with the lock cylinder assembly at one end of the handle assembly within the base. Simultaneously, the bottom of the lock cylinder assembly is inserted into the lock hole of the base via the handle. The bottom locking plate of the lock cylinder assembly rotates and is then misaligned and locked to the bottom of the lock hole in the base, or to the lock groove within the quick-release cover plate. The locking plate is oblong in shape. The above describes a structural embodiment where the lock plate structure, combined with the lock cylinder, fixes the handle of the handle assembly within the base, or allows it to be opened from within the base for use.
[0011] The base has L-shaped quick-installation ribs symmetrically arranged on both sides of the plane between the two ends of the bottom, which correspond to the outer diameter of the head block groove to form a rectangular fitting area. The rectangular fitting area and quick-installation cover plate at the bottom of the base correspond to two rectangular mounting holes on the door panel.
[0012] This invention features a reasonable structural design, convenient and quick installation, good stability and firmness after installation, and diverse structural forms; it is suitable for use as a quick-installation outdoor mechanical lock, as well as for structural improvements to similar products.

[0022] The structure and use of the present invention will now be further described with reference to the accompanying drawings. Figures 1-8 As shown, the quick-release lock has a quick-release mechanism at one end of the base 1 on one side of the pivot 4. The quick-release mechanism includes a first latch block 6 and a second latch block 9 symmetrically arranged on both sides, and a slanted latch block 5 between the first latch block and the second latch block, and a spring 8 for resetting the slanted latch block. The first latch block, the second latch block and the slanted latch block are fixedly and limited in the head block groove 101 at the bottom of the base by the head cover plate 7. One end of the first latch block, the second latch block and the slanted latch block extends out of the mounting edge 102 at the bottom of the base, thereby limiting the base from sliding out of the door panel mounting hole. Its specific structure is as follows: The first and second locking tongue blocks are L-shaped, and the bottom and top of the oblique tongue block are provided with an upper guide groove 501 and a lower guide groove 502 that are intersecting and obliquely arranged respectively. The first and second locking tongue blocks are provided with a first guide rib 601 and a second guide rib 901 that protrude inward at the end facing the oblique tongue block respectively. When the first locking tongue block is inserted into the bottom head block groove of the base from the bottom of the oblique tongue block, the first guide rib of the first locking tongue block is inserted into the lower guide groove of the oblique tongue block. When the second locking tongue block is inserted into the bottom head block groove of the base from the top of the oblique tongue block, the second guide rib of the second locking tongue block is inserted into the upper guide groove of the oblique tongue block. The positioning post 701 on one side of the head cover plate is inserted into the positioning sliding hole 503 of the oblique tongue block. The other end of the oblique tongue block in the bottom head block groove of the base abuts against the outer diameter of the base through the spring shaft.
[0023] The heads of the first locking tongue block, the second locking tongue block, and the inclined tongue block are respectively inclined towards the mounting plate of the base, with the length of the inclined side being greater than the length of the inclined side on the other side. L-shaped latching posts 702 are provided at the bottom corners of the head cover plate, and the latching posts of the head cover plate are interference-fitted to the mounting rib posts 103 protruding from the outer diameter of the head block groove at the bottom of the base. The height of the head cover plate of the quick-release mechanism is lower than the height of the opening at the bottom of the base where the rotating shaft extends. A quick-release cover plate 10 is provided at the bottom of the base at the other symmetrical end of the rotating shaft, and a latching barb 1001 extending beyond the mounting edge of the base's bottom is provided on the outer side of the quick-release cover plate at the other end of the base. The quick-release cover plate aligns with the lock cylinder assembly at one end of the handle assembly inside the base. Simultaneously, the bottom of the lock cylinder assembly is inserted into the lock hole of the base via the handle. The bottom locking plate 2 of the lock cylinder assembly rotates and is then offset and locked to the bottom of the lock hole in the base, or to the lock groove within the quick-release cover plate. The locking plate is waist-shaped. Symmetrically arranged on both sides of the plane between the two ends of the base bottom are L-shaped quick-release ribs 104, corresponding to the outer diameter of the head block groove, forming a rectangular fitting area. The rectangular fitting area at the bottom of the base and the quick-release cover plate correspond to two rectangular mounting holes on the door panel, respectively.
[0024] When using, align the mounting edge at the bottom of the base with the mounting hole on the door panel. First, hook the quick-release cover plate at an angle towards one end of the mounting hole on the door panel. Then, press the quick-release mechanism at the other end of the base's bottom onto the other end of the mounting hole on the door panel. To remove the quick-release lock, first press the angled lock block. The angled lock block will retract the first and second latch blocks on both sides. From this end, you can rotate downwards and outwards to remove the hook of the quick-release cover plate at the other end of the base's bottom.
[0025] This quick-install lock has the following advantages: 1. It fills the gap in outdoor quick-install locks. Currently, quick-install locks are mainly designed for indoor use, and there are no quick-install locks for outdoor use. 2. It meets the IP65 requirement for quick-install locks. Conventional quick-install locks have limited protective effects due to structural issues. The modified structure of this lock better meets the protection performance requirements. 3. It reduces customer installation time. Outdoor locks are generally installed using screw fastening, requiring extra installation tools and time. This lock does not use fasteners; it can be installed simply by pressing it down by hand, saving a lot of time. This quick-install lock solves the following problems: 1. Indoor use has poor protective effect; 2. Its application is limited, and the plate thickness is generally a fixed value.
