Description

Technical Field

[0001] This invention belongs to the field of lock technology, and in particular relates to a deadbolt smart lock installation mechanism. Background Technology

[0002] A deadbolt lock has no spring; when opening, the lock cylinder rotates forward, causing the bolt to retract, and when closing, the lock cylinder rotates backward, causing the bolt to extend. Therefore, there is no way to use a rigid plate to push the bolt back, making deadbolt locks more secure than spring locks. Smart locks refer to locks that are improved upon traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management.

[0003] Currently, most smart locks are installed by drilling grooves in the door panel to be installed, and then using multiple screws to install the lock body onto the door panel. This method not only reduces the stability of the lock body on the door panel, but also affects the aesthetics of the door panel and the smart lock installation due to the large number of screw holes drilled in the door panel. Furthermore, it requires disassembling the parts to remove the installed smart lock body from the door panel, thus affecting the efficiency of installing and removing the smart lock body from the door panel. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a lock mounting mechanism for a smart lock, comprising a lock body and a mounting base. The lock body has a lock base plate at its front end, and a latch connector is mounted in the middle of the lock base plate. The mounting base is fixedly mounted at the door lock mounting position, and the mounting base has multiple through-slide grooves. A square slider is slidably mounted in the mounting base via an elastic element, and the square slider has a locking groove. Multiple latching blocks are correspondingly provided on the lock base plate and the mounting base, and the multiple latching blocks pass through the through-slide grooves and engage in the corresponding locking grooves. The latch connector extends from a through hole in the middle of the mounting base.

[0006] Furthermore, the mounting base is annularly open, the through grooves are distributed in a square shape inside the mounting base, the annular wall of the mounting base is provided with through holes corresponding to the elastic element, and the through holes correspond to the side of the square slider. The middle part of the mounting base protrudes outward to form a raised cavity, and the middle part of the raised cavity is provided with a through hole for the tongue connector to extend out.

[0007] Furthermore, the rectangular slider is sleeved on the outside of the protruding cavity, and the four corners of the rectangular slider are all arc-shaped corners. The bayonet grooves are symmetrically opened on the two side walls of the rectangular slider. Limiting posts are installed on the frame walls of the rectangular slider corresponding to the through-hole, and the limiting posts are slidably inserted into the through-hole.

[0008] Furthermore, the top surfaces of the multiple sets of symmetrical latching blocks are all chamfered. Each latching block includes an inner latching block and an outer latching block. The inner latching block is formed on the lock base plate, and its engagement notch faces the direction of the elastic element. The inner latching block slides through the through groove, and the inner latching block and the inner latching groove near the side groove wall of the elastic element slide and engage. The outer latching block is formed on the mounting base, and the engagement groove of the outer latching block faces the direction of the protruding cavity. The side wall of the inner latching block near the outer latching block abuts against the bottom of the inner latching groove. The inner wall of the engagement groove of the outer latching block abuts against the outer frame wall of the square block slider. The width of the outer latching block is greater than the thickness of the inner latching block.

[0009] Furthermore, the elastic element includes a torsion spring, a limiting pin, and a limiting block. The spring coil of the torsion spring is sleeved on the limiting pin, and the limiting pin is vertically fixed inside the mounting base on the side away from the through-hole. The top of the limiting pin forms a right-angle block facing the side of the square block slider, and the right-angled surface of the right-angle block abuts against the top surface of the spring coil of the torsion spring. The square block slider is symmetrically fixed to the side near the torsion spring, and a limiting groove is opened at the bottom of the limiting block, and the spring rod of the torsion spring is engaged in the limiting groove.

[0010] Furthermore, the opening of the annularly shaped mounting base is detachably covered with a sealing cap, and the sealing cap has an avoidance hole at its center. The outer annular surface of the mounting base forms multiple annular protrusions, and the sealing cap is engaged with the annular protrusions on the mounting base through the multiple annular protrusions formed on the inner ring.

[0011] Furthermore, at least four limiting pins are installed inside the cover of the sealing cap, and each limiting pin corresponds to a slot opened on the inner side of the square slider. Each limiting pin is pressed into the notch formed directly between the inner side block and the groove wall of the inner side slot after engagement.

[0012] Furthermore, the sealing cap has at least four threaded holes on its cover body, and the limiting pin is threadedly connected to the threaded hole by a screw. Each limiting pin also has a threaded connection hole at its bottom end, and the threaded connection hole and the threaded hole are the same size. The diameter of the limiting pin is smaller than the diameter of the through hole.

[0013] The present invention has the following beneficial effects:

[0014] 1. The square slider of this invention slides and engages with the engagement notch of the latch block, thereby enabling the latch block and the square slider sliding in the mounting base to cooperate, quickly and stably installing the lock body onto the door panel without requiring numerous screw holes and screws on the door panel for installation. When the lock body needs to be removed from the door panel for repair or replacement, the disassembly personnel can push the square slider towards the elastic element, causing the square slider to disengage from the engagement notch of the latch block. This allows the multiple latching slots to align synchronously with multiple sets of latch blocks. Then, pressing the latch connector or pulling the lock body outwards causes the multiple sets of latch blocks to be quickly pushed out from the through-slide grooves on the mounting base. This facilitates the quick removal and replacement of the lock body from the door panel without damaging the door panel or the mounting base.

[0015] 2. This invention utilizes the engaging groove of the outer locking block to slidably engage with the outer surface of the square block slider, vertically constraining and fixing the square block slider within the mounting base. The inner locking block, through its engaging notch facing the elastic element and its interaction with the elastic element, horizontally constrains and fixes the square block slider. The engaging groove of the outer locking block fits against the outer frame sidewall of the square block slider, while the inner locking block fits against the groove wall of the inner locking slot, thus vertically constraining and fixing the square block slider. The interaction of the inner locking block, outer locking block, and elastic element allows for multi-angle constraint and fixation of the square block slider within the mounting base, enabling quick and stable installation of the lock body onto the mounting base.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0028] Please see Figures 1-7As shown, the present invention is a smart lock installation mechanism, including a lock body 1 and a mounting base 2. The front end of the lock body 1 is provided with a lock base plate 11, and a latch connector 12 is installed in the middle of the lock base plate 11. The mounting base 2 is fixedly installed in the installation position of the door lock, and multiple through grooves 21 are provided on the mounting base 2. A square block slider 3 is slidably arranged in the mounting base 2 through an elastic element 5, and a bayonet groove 31 is provided on the square block slider 3. Multiple buckle blocks 4 are correspondingly provided on the lock base plate 11 and the mounting base 2, and the multiple buckle blocks 4 pass through the through grooves 21 and engage in the corresponding bayonet grooves 31. The latch connector 12 extends out from the through hole 22 opened in the middle of the mounting base 2.

[0029] In the design scheme of this invention, the present invention only requires fixing the mounting base 2 to the door panel of the door lock to be installed with screws, then aligning the latch connector 12 on the lock body 1 with the through hole 22, then installing the square block slider 3 into the cavity of the mounting base 2, and then, through the cooperation of the buckle block 4 and the elastic element 5 on the mounting base 2, fitting the square block slider 3 into the cavity of the mounting base 2, then aligning the multiple sets of buckle blocks 4 on the lock base plate 11 with the multiple through grooves 21 opened on the mounting base 2, and then pressing the lock body 1 forcefully towards the door, causing the multiple sets of buckle blocks 4 to extend out of the through grooves 21. At this time, the top slope of the buckle block 4 will abut against the edge of the slot 31 opened on the square block slider 3, and as the buckle block 4 is continuously pushed out, it will generate a horizontal component force on the square block slider 3, which will cause the square block slider 3 to overcome the elastic element 5 and slide towards the elastic element 5. When the buckle block 4 is completely inserted from the through groove 21 and engaged in the slot 31, the elastic element will then... When the elastic restoring force of component 5 pushes the square slider 3 back to its initial position, the square slider 3 will slide and engage with the engagement notch 411 of the latch block 4. This allows the latch block 4 and the square slider 3, which is slidably set in the mounting base 2, to quickly and stably install the lock body 1 onto the door panel without requiring many screw holes or screws to be drilled on the door panel. When the lock body 1 needs to be removed from the door panel for repair or replacement, the disassembly personnel can push the square slider 3 towards the direction of the elastic component 5, causing the square slider 3 to disengage from the engagement notch 411 of the latch block 4. This allows the multiple latching slots 31 to align synchronously with the multiple sets of latch blocks 4. Then, by pressing the latch connector 12 or pulling out the lock body 1, the multiple sets of latch blocks 4 will be quickly pushed out from the through grooves 21 on the mounting base 2. This facilitates the quick removal and replacement of the lock body 1 from the door panel without damaging the door panel or the mounting base 2.

[0030] In one embodiment of the present invention, the mounting base 2 is annularly open, the through groove 21 is distributed in a square frame shape inside the mounting base 2, the annular wall of the mounting base 2 is provided with through insertion holes 23 corresponding to the elastic member 5, and the through insertion holes 23 correspond to the side of the square slider 3. The middle part of the mounting base 2 protrudes outward to form a protruding cavity 24, and the middle part of the protruding cavity 24 is provided with a through hole 22 for the tongue connector 12 to extend out.

[0031] In the design of this invention, the through-slide groove 21 is arranged in a square shape, which facilitates the engagement of the square slider 3 with the snap-fit ​​block 4 into the annular open mounting base 2. The through-hole 23 is designed so that when the lock body 1 needs to be removed from the mounting base 2, a tool is inserted into the through-hole 23, which pushes the square slider 3 towards the elastic member 5, causing the snap-fit ​​groove 31 on the square slider 3 to disengage from the snap-fit ​​block 4. Then, the lock body 1 is pulled, causing the latch connector to... 12 disengages from the through hole 22 in the middle of the protruding cavity 24, thereby enabling the lock body 1 to be quickly removed from the installed door panel for replacement or repair; the design of the protruding cavity 24 not only facilitates the extension of the latch connector 12 out of the mounting base 2, but also the recessed cavity inside the protruding cavity 24 is used to accommodate the screws fixing the mounting base 2, so that the lock base plate 11 can be flat against the bottom surface of the mounting base 2, thereby enabling the latch block 4 to be accurately engaged with the square slider 3, realizing the quick installation and fixation of the lock body 1.

[0032] In one embodiment of the present invention, the square frame slider 3 is sleeved on the outside of the protruding cavity 24, and the four corners of the square frame slider 3 are all arc corners. The bayonet groove 31 is symmetrically opened on the two side walls of the square frame slider 3. The limit post 32 is installed on the frame wall of the square frame slider 3 corresponding to the through hole 23, and the limit post 32 is slidably inserted into the through hole 23.

[0033] In the design of this invention, the slider is designed in a square frame shape, which facilitates the installation of the square frame slider 3 into the cavity of the mounting base 2, and avoids interference caused by the protruding cavity 24 in the middle. The symmetrical opening of the bayonet groove 31 and its cooperation with the buckle block 4 not only facilitate the positioning and installation of the square frame slider 3 into the mounting base 2, but also facilitate the fixing and fastening of the lock body 1 into the mounting base 2, realizing the quick and accurate installation of the lock body 1. Through the design of the limiting post 32, when the square frame slider 3 slides and engages with the buckle block 4 into the mounting base 2, the elastic element 5 will push the square frame slider 3 towards the through hole 23. At this time, the limiting post 32 will be inserted into the through hole 23, so that it cooperates with the buckle block 4 and the elastic element on the mounting base 2. Part 5 limits and fixes the square slider 3 in the mounting base 2 in the planar direction; when the buckle block 4 on the lock base plate 11 pushes the edge of the slot 31 through the through groove 21, the limiting post 32 inserted into the through hole 23 will limit the square slider 3 in the vertical direction, preventing the buckle block 4 on the lock base plate 11 from pushing too hard and causing the square slider 3 to lift out of the cavity of the mounting base 2. The limiting post 7 is slidably inserted into the through hole 23, and the length of the limiting post 7 is similar to the sliding distance of the square slider 3. Therefore, it will not interfere with the normal sliding of the square slider 3, nor will it affect the sliding and locking installation of the square slider 3 in the mounting base 2.

[0034] In one embodiment of the present invention, the top surfaces of the multiple sets of symmetrical latching blocks 4 are all chamfered. The latching block 4 includes an inner latching block 41 and an outer latching block 42. The inner latching block 41 is formed on the locking base plate 11, and its engagement notch 411 faces the elastic member 5. The inner latching block 41 slides through the through groove 21, and the inner latching block 41 is correspondingly engaged with the inner latching groove 31 near the side groove wall of the elastic member 5. The outer latching block 42 is formed on the mounting base 2. The engagement groove 421 of the outer latching block 42 faces the protruding cavity 24. The side wall of the inner latching block 41 near the outer latching block 42 abuts against the bottom of the inner latching groove 31. The inner wall of the engagement groove 421 of the outer latching block 42 abuts against the outer frame wall of the square slider 3. The width of the outer latching block 42 is greater than the thickness of the inner latching block 41.

[0035] In the design of this invention, a rectangular outer locking block 42 is formed on the mounting base 2. When the rectangular slider 3 is installed into the cavity of the mounting base 2, the locking groove 31 on the outer side of the rectangular slider 3 is first aligned with the outer locking block 42. Then, the rectangular slider 3 is pressed down to fit against the cavity wall of the mounting base 2. The upper groove wall of the engaging groove 421 of the outer locking block 42 aligns with the outer surface of the rectangular slider 3, and the inner groove wall of the engaging groove 421 corresponds to the outer frame side wall of the rectangular slider 3. Then, the compressed elasticity is released. The elastic restoring force of component 5 will push the square slider 3 to slide towards the through-hole 23, and the limiting post 32 will slide into the through-hole 23. When the square slider 3 slides, the engaging groove 421 of the outer locking block 42 will be misaligned with the outer locking groove 31, which will cause the engaging groove 421 of the outer locking block 42 to slide and engage with the outer frame surface and the outer frame side wall of the square slider 3. This will enable the square slider 3 to slide and install into the mounting base 2 without automatically detaching from the mounting base 2.When the lock body 1 moves the lock base plate 11 closer to the inner wall of the mounting base 2, the inner locking block 41 formed on the lock base plate 11 will pass through the through groove 21, and its chamfered surface will contact the groove wall of the inner locking groove 31. This will cause the continuously pushed inner locking block 41 to push the square slider 3 towards the elastic member 5, so that the inner locking block 41 will be completely aligned with the inner locking groove 31 and extend out. When the locking notch 411 of the inner locking block 41 corresponds to the side groove wall of the inner locking groove 31, the elastic member 5 will then release its spring. The restoring force pushes the square slider 3 towards the through-hole 23, allowing the engaging notch 411 of the inner locking block 41 to engage with the side groove wall of the inner locking groove 31. This engagement between the inner locking block 41 and the square slider 3 securely fixes the lock base plate 11 to the mounting base 2. Since the square slider 3 is first engaged into the cavity of the mounting base 2 by multiple outer locking blocks 42, preventing it from detaching from the cavity, and then further engaged by the inner locking block 41 and the square slider 3... The lock body 1 can be quickly and stably installed onto the mounting base 2. Because the outer locking block 42's engaging groove 421 engages with the outer surface of the square slider 3, it vertically constrains and fixes the square slider 3 within the mounting base 2. The inner locking block 42, through its engaging notch 411 facing the elastic element 5 and its interaction with the elastic element 5, horizontally constrains and fixes the square slider 3. The outer locking block 42's engaging groove 421 fits snugly against the square slider 3. The inner locking block 41 of the outer frame sidewall fits into the groove wall of the inner locking slot 31, thereby constraining and fixing the frame slider 3 in the vertical direction. This, in turn, allows the inner locking block 41, the outer locking block 42, and the elastic element 5 to cooperate in fixing the frame slider 3 to the mounting base 2 at multiple angles. This prevents the frame slider 3 from freely sliding within the cavity of the mounting base 2 during normal unlocking, further improving the firmness and stability of the lock body 1 mounted on the mounting base 2.

[0036] In one embodiment of the present invention, the elastic element 5 includes a torsion spring 51, a limiting pin 52, and a limiting block 53. The spring coil of the torsion spring 51 is sleeved on the limiting pin 52, and the limiting pin 52 is vertically fixed inside the mounting base 2 on the side away from the through hole 23. The top of the limiting pin 52 forms a right-angled block 521 facing the side of the square slider 3, and the right-angled surface of the right-angled block 521 abuts against the top surface of the spring coil of the torsion spring 51. The square slider 3 is symmetrically fixed with the limiting block 53 near the side of the torsion spring 51. The bottom of the limiting block 53 is provided with a limiting groove 531, and the spring rod 511 of the torsion spring 51 is engaged in the limiting groove 531.

[0037] In the design of this invention, the spring coil of the torsion spring 51 is sleeved on the limiting post 52, and the right-angle locking block 521 will abut and limit the spring coil to prevent the torsion spring 51 from detaching from the limiting post 52. The limiting slot 531 on the limiting block 53 near the torsion spring 51 of the square slider 3 will engage and limit the spring rod 511 of the torsion spring 51, so that it can stably push the square slider 3 to slide within the mounting base 2. Since the torsion spring 51 is detachably engaged with the square slider 3, it is convenient for the square slider 3 to be quickly disassembled.

[0038] As one embodiment of the present invention, the opening of the annularly open mounting base 2 is detachably covered with a sealing cover 6, and the center of the sealing cover 6 is provided with an avoidance hole 61. The outer annular surface of the mounting base 2 forms multiple annular protrusions 62, and the sealing cover 6 is engaged with the annular protrusions 62 on the mounting base 2 through the multiple annular protrusions 62 formed on the inner ring.

[0039] In the design of this invention, after the lock body 1 is installed on the mounting base 2, the operator presses and fastens the sealing cover 6 onto the annular outer ring of the mounting base 2, so that the annular protrusion 62 on the sealing cover 6 and the annular protrusion 62 on the mounting base 2 are engaged with each other, so that the sealing cover 6 can seal the inner cavity of the mounting base 2, preventing dust or debris from entering the cavity of the mounting base 2 and affecting the normal sliding of the square slider 3, thereby affecting the normal disassembly of the lock body 1 from the mounting base 2.

[0040] As one embodiment of the present invention, at least four limiting pins 7 are installed inside the cover of the sealing cover 6, and each limiting pin 7 corresponds to the slot 31 opened on the inner side of the square slider 3. Each limiting pin 7 is pressed into the notch formed directly between the inner side block 41 and the groove wall of the inner side slot 31 after the lock is engaged.

[0041] In the design of this invention, when the sealing cover 6 is vertically fastened into the mounting base 2, multiple limiting pins 7 will be elastically squeezed and inserted into the notch, so that the inner locking block 41 is abutted and locked into the inner locking groove 31, preventing the tongue connector 12 from being subjected to a large torsional force, which would cause the inner locking block 41 on the lock base plate 11 to vibrate and slide on the square slider 3, thereby affecting the safety and stability of the lock body 1 in use.

[0042] As one embodiment of the present invention, the sealing cover 6 has at least four threaded holes on its cover body, and the limiting plug 7 is threadedly connected to the threaded hole by a screw 71. Each limiting plug 7 also has a threaded connection hole 72 at its bottom end, and the threaded connection hole 72 and the threaded hole are the same size. The diameter of the limiting plug 7 is smaller than the diameter of the through hole 23.

[0043] In the design of this invention, when the lock body 1 needs to be disassembled for repair or replacement, the sealing cover 6 is first removed from the mounting base 2, and then the screw 71 of the limiting pin 7 is removed from the threaded hole. Then, the removed limiting pin 7 is connected to the upper and lower parts of the screw 71 through the threaded connection hole 72 and the screw 71 to form a pin bar. The connected pin bar is then inserted into the through hole 23 as a tool, which can push the square block slider 3 to slide in the cavity of the mounting base 2, so that the bayonet groove 31 is aligned with the buckle block 4, so that the square block slider 3 is disengaged from the buckle block 4. Then, the latch connector 12 is pressed or the lock body 1 is pulled to quickly remove the lock body 1 from the mounting base 2 without the need to find a separate disassembly tool.
