DETAILED DESCRIPTION
[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0026] Reference Figure 1-7 As shown, an ecological lock with differentiated internal and external handle control structure includes a lock body shell 1, a lock tongue 2 slidably connected to the lock body shell 1, a lock core assembly 3 rotatably connected to the lock body shell 1, and a limiting component 4. A reset assembly 5 for resetting the lock core assembly 3 is provided in the lock body shell 1, and handle assemblies are provided on both sides of the lock body shell 1.
[0027] The lock core assembly 3 includes a first locking plate 6 and a second locking plate 7. The first locking plate 6 and the second locking plate 7 are coaxially connected for rotation. The first locking plate 6 and the second locking plate 7 are both provided with a first driving block 8 for driving the lock tongue 2 to move. The second locking plate 7 is provided with a first limiting block 9.
[0028] The limiting component 4 is arranged on one side of the lock core assembly 3, and the limiting component 4 is provided with a lock hole 10 for inserting the key, and the limiting component 4 is provided with a second limiting block 11, and both sides of the second limiting block 11 are provided with second driving blocks 12 that cooperate with the first driving block 8, and the first limiting block 9 and the second limiting block 11 are provided with mutually cooperating planes. When the first driving block 8 rotates toward the limiting component 4, the first driving block 8 abuts against the second driving block 12 to make the second limiting block 11 rotate close to the first limiting block 9, thereby limiting the first driving block 8 on the second lock plate 7 to drive the lock tongue 2 to unlock.
[0029] In this solution, the first locking piece 6 is applied on the indoor side and the second locking piece 7 is applied on the outdoor side. When the door needs to prevent outdoor people from entering, the connecting shaft 32 on the first locking piece 6 or the second locking piece 7 is rotated toward the direction of the limiting component 4, so that the second limiting block 11 on the limiting component 4 is close to the first limiting block 9 on the second locking piece 7. When the first limiting block 9 is driven close to the second limiting block 11 by the first driving block 8, the two planes cooperate directly to limit the second locking piece 7 from driving the lock tongue 2 to unlock and open the door. Since the first locking piece 6 and the second locking piece 7 are rotatably connected, the first locking piece 6 can freely control the opening and closing of the door without being affected by the limiting component 4, and can limit the connecting shaft 32 on the outdoor side from rotating to open the door.
[0030] The first locking piece 6 and the second locking piece 7 are both provided with a connecting hole 13, and a connecting shaft 32 is installed in each of the connecting holes 13 to prevent rotation. The connecting shaft 32 with anti-rotation prevents relative rotation between the first locking piece 6 and the second locking piece 7. The connecting hole 13 and the connecting shaft 32 are anti-rotationally matched so that the first locking piece 6 or the second locking piece 7 can rotate along with the connecting shaft 32. The provision of the connecting shaft 32 also facilitates the subsequent further installation of the handle.
[0031] The second locking plate 7 includes a first component 14 and a second component 15. The second component 15 is installed between the first component 14 and the first locking plate 6. The first driving block 8 is provided on the first component 14, and the first limiting block 9 is provided on the second component 15. The first component 14 and the second component 15 are both installed on the connecting shaft 32 corresponding to the second locking plate 7 and engage with the connecting shaft 32 to prevent rotation. Splitting the second locking plate 7 into the first component 14 and the second component 15 facilitates the processing and manufacturing of the mold. When the connecting shaft 32 rotates, the first component 14 and the second component 15 installed on the connecting shaft 32 can rotate along with the connecting shaft 32. In this embodiment, an annular protrusion 16 is provided on the first locking piece 6 and the first component 14 on the side facing the second component 15, and an annular groove 17 is provided on both sides of the second component 15 to abut against the annular protrusion 16, or an annular groove 17 is provided on the first locking piece 6 and the first component 14 on the side facing the second component 15, and an annular groove 17 is provided on both sides of the second component 15 to abut against the annular protrusion 16. The cooperation between the annular protrusion 16 and the annular groove 17 enables rapid positioning and installation of two adjacent parts, reduces axial movement, and improves installation stability.
[0032] The connecting shaft 32 is provided with a plurality of limiting protrusions 21 on its circumference, and the limiting protrusions 21 abut against the outer side of the connecting hole 13 to limit the installation depth of the connecting shaft 32. The provision of the plurality of limiting protrusions 21 facilitates the rapid installation of the connecting shaft 32 and avoids the connecting shaft 32 from being installed too deep or too shallow.
[0033] The lock body locking mechanism described above has a swinging portion 23 on the limiting component 4, and bosses 24 are provided on both sides of the swinging portion 23. The lock body shell 1 has guide grooves 25 on both sides corresponding to the bosses 24. The bosses 24 extend into the guide grooves 25. The swinging portion 23 and the limiting component 4 are integrally formed. The guide grooves 25 are used to limit the maximum swinging angle of the boss 24, and are also used to improve the rotation stability of the limiting component 4.
[0034] The handle assembly includes a handle base 18 and a grip 19 rotatably connected to the handle base 18. The grip 19 is provided with a connecting groove 20 for installing a connecting shaft 32. The connecting shaft 32 and the connecting groove 20 are anti-rotation matched. When the handle 19 is rotated by force, the first locking plate 6 or the second locking plate 7 is driven to open the door or lock the second locking plate 7. A plurality of limiting protrusions 21 are provided on the circumference of the connecting shaft 32. The limiting protrusions 21 abut against the outer side of the connecting hole 13. The bottom of the connecting groove 20 is provided with a first return spring 22 that pushes the connecting shaft 32 toward the connecting hole 13. The first spring is provided so that the limiting protrusion 21 on the connecting shaft 32 can fully abut against the outer side of the connecting hole 13. The position of the handle base 18 corresponding to the lock hole 10 is provided with a keyhole for inserting a key and connected to the lock hole 10. When the outside handle needs to be unlocked, the key is inserted into the keyhole and cooperates with the lock hole 10 to make the second limit move away from the first limiting block 9, thereby releasing the restriction on the outside handle.
[0035] The reset assembly 5 includes a spring seat 26 slidably connected to the shell, and a second reset spring 27 is provided between the spring seat 26 and the lock body shell 1. The spring seat 26 is provided with a flat surface on the side facing the lock core assembly 3. The first locking piece 6, the first component 14, and the second component 15 are each provided with an abutment block 28 on one side close to the lock core seat. The abutment block 28 is provided with a flat surface that abuts the spring seat 26. The lock body shell 1 is provided with a slide rail for positioning and sliding the spring seat 26. When the connecting shaft 32 rotates to open the lock tongue 2, the spring seat 26 is retreated by the pressure of the abutment block 28. When the connecting shaft 32 releases the external force, the spring seat 26 is ejected, so that the first locking piece 6 or the first component 14 and the second component 15 return to their initial positions.
[0036] The limiting component 4, first locking plate 6, and first component 14 are each provided with a stepped surface 29 for cooperating with the lock housing 1 for positioning. The stepped surface 29 facilitates positioning of each component on the lock housing 1. The first locking plate 6 and first component 14 are each provided with a slider 30. The lock housing 1 is provided with a slot 31 at a position corresponding to the slider 30. The slider 30 is mounted within the slot 31. The slot 31 is provided to guide the slider 30 and also to limit the maximum sliding angle of the slider 30.
