Description

Technical Field

[0001] The invention belongs to the field of door locks and relates to a novel unlocking structure. Background Art

[0002] There are two types of handles on the market today: rotary unlocking handles, which rotate a core rod to unlock the lock body; and fixed handles, commonly used on smart locks. After the smart lock is unlocked, a motor rotates to unlock the lock body. Both types of handles use a rotary unlocking mechanism. There is no other unlocking mechanism on the market that doesn't use a smart lock and doesn't rely on a rotary unlocking mechanism. Summary of the Invention

[0003] In response to the above problems, the present invention provides a new unlocking structure. The device has a simple structure and can realize direct-push unlocking by directly pushing the pressing part on the handle in conjunction with the direct-push square core plate on the lock body. It has the advantage of being able to unlock with a fixed handle without using a smart lock.

[0004] The object of the present invention is achieved like this: A novel unlocking structure includes two handles and a lock body arranged between the two handles: The lock body includes a lock shell, a magnetic lock tongue is provided in the lock shell, a lock tongue hole is formed on the front end of the lock shell for the magnetic lock tongue to extend, a lock tongue pull plate is connected to the rear end of the magnetic lock tongue, a toggle groove is formed on the lock tongue pull plate, a toggle plate is further provided at the rear of the magnetic lock tongue, the toggle plate is rotatably connected to the lock shell, a toggle end is extended from the toggle plate toward the toggle groove, and the toggle end is arranged in the toggle groove; a straight-push square core plate is provided at the rear of the toggle plate, the straight-push square core plate moves back and forth in the lock shell, a core groove is formed on the straight-push square core plate, a transverse groove is formed on the lock shell corresponding to the core groove, the straight-push square core plate extends a straight-push end toward the front, and a linkage end is provided on the toggle plate corresponding to the straight-push end; The two handles each include a handle shell, a mounting cavity is formed on the handle shell, the two mounting cavities are arranged opposite to each other, an unlocking sliding block is arranged in the mounting cavity, the unlocking sliding block can slide back and forth in the mounting cavity, a through slot is provided at the rear end of the mounting cavity, and the rear end of the unlocking sliding block extends backward to form a pressing portion; a limiting portion is also provided in the mounting cavity, and the unlocking sliding block is formed with a limiting end matching the limiting portion, and the limiting portion is arranged behind the limiting end. A return spring is also provided in the mounting cavity, and a return spring positioning end is provided in the mounting cavity, one end of the return spring is connected to the return spring positioning end, and the other end of the return spring is connected to the unlocking sliding block, and the return spring always gives the unlocking sliding block a force to move backward, so that the limiting end of the unlocking sliding block rests on the limiting portion; A core rod is connected between the two unlocking sliding blocks, and the core rod passes through the core groove of the straight-push square core plate. The unlocking sliding block moves back and forth, driving the core rod to move back and forth and driving the straight-push square core plate to move back and forth. The straight-push end of the straight-push square core plate drives the linkage end of the toggle plate to move, thereby rotating the toggle plate. The toggle end of the toggle plate rotates in the toggle groove, driving the lock tongue pull plate to move backward, so that the magnetic lock tongue is retracted into the lock shell.

[0005] With the above arrangement, whether unlocking the door from inside or outside, one only needs to push the pressing portion forward to move the unlocking slider forward. Since a core rod is connected between the two unlocking sliders, the forward movement of one unlocking slider will drive the core rod and the other unlocking slider forward together. Furthermore, since the core rod passes through the core groove of the straight-push square core plate, the forward movement of the core rod also causes the straight-push square core plate to move forward. The straight-push end of the straight-push square core plate drives the linkage end of the toggle plate to move, thereby rotating the toggle plate. The toggle end of the toggle plate rotates in the toggle groove, driving the lock bolt pull plate backward, causing the magnetic lock bolt to retract into the lock housing, thus completing the unlocking.

[0006] After unlocking, under the action of the reset spring, the reset spring will move the unlocking sliding block backward and reset, and at the same time drive the straight-pushing square core plate backward and reset through the core rod, making it convenient for the next unlocking.

[0007] Through the above settings, you can use a fixed handle without using a smart lock, or you can push the pressing part on the handle directly in conjunction with the straight-push square core plate on the lock body to achieve straight-push unlocking.

[0008] The present invention is further configured as follows: the lock tongue pull plate is arranged below the toggle plate, the toggle plate extends a toggle end downward, the toggle end extends downward into the toggle groove of the lock tongue pull plate, the linkage end is arranged above the toggle plate, the upper end of the straight-push square core plate extends forward to the straight-push end, the straight-push square core plate moves forward to drive the linkage end to move forward, and the toggle plate rotates accordingly to cause the toggle end to move backward with the pull plate to retract the magnetic lock tongue into the lock shell.

[0009] Through the above arrangement, the lock tongue pull plate is arranged at the bottom, the straight push end is arranged at the top, and the toggle plate is arranged in the middle, which can maximize the space utilization of the installation slot in the lock shell, thereby reducing the size of the lock body.

[0010] The present invention is further configured as follows: a tension spring column is formed in the lock housing, the tension spring column is connected to a tension spring, the other end of the tension spring is connected to the magnetic lock tongue, and the tension spring always gives the magnetic lock tongue a force to retract the lock housing.

[0011] The setting of the tension spring can prevent the magnetic lock tongue from shaking and extending out of the lock shell when the lock is unlocked, thereby causing scratches and damage.

[0012] The present invention is further configured as follows: a limit block is formed on the lock shell, a guide gap is formed between the limit block and the lower wall of the lock shell, and the lock tongue pull plate is arranged in the guide gap; a positioning lug is also formed on the lock tongue pull plate, and a positioning block is also formed on the lock shell corresponding to the positioning lug, and the positioning lug is arranged between the limit block and the positioning block.

[0013] Through the above settings, the lock tongue pull plate can be guided, making the movement of the lock tongue pull plate more stable, thereby indirectly making the movement of the magnetic lock tongue more stable; through the setting of the positioning lug, the extension and retraction distance of the lock tongue pull plate can be limited, thereby limiting the extension and retraction distance of the magnetic lock tongue.

[0014] The present invention is further configured such that: the straight-push square core plate is further provided with a guide boss corresponding to the transverse displacement groove.

[0015] By setting the guide boss, the moving range of the straight-push square core plate can be limited through the transverse groove, and it can also play a guiding role.

[0016] The present invention is further configured as follows: a reverse locking lock core is further provided in front of the straight-push square core plate, the reverse locking lock core is rotatably connected to the lock housing, and a reverse locking end is formed on the reverse locking lock core.

[0017] Through the setting of the reverse locking lock core, reverse locking can be achieved when the reverse locking end is against the straight-push square core plate.

[0018] The present invention is further configured as follows: a rotating groove is provided in the mounting cavities of the two handle shells, a rotating part is provided in the rotating groove, an anti-locking bar is connected between the two rotating parts, the anti-locking bar passes through the anti-locking lock core, and the rotation of the rotating part drives the anti-locking bar to rotate and drives the anti-locking lock core to rotate.

[0019] Through the above arrangement, the anti-lock bar can be controlled to rotate by the rotating member, thereby causing the anti-lock lock core to rotate to achieve anti-locking.

[0020] The present invention is further configured such that the rotating part of one handle is a knob, and the rotating part of the other handle is a key core.

[0021] With the above arrangement, the door can be locked from outside by the key cylinder of the outside handle, and from inside by the knob of the inside handle.

[0022] The present invention is further configured as follows: a suppression end is also formed on the anti-lock lock core, and the suppression end is arranged in front of the anti-lock end. When the magnetic lock tongue retracts, the lock tongue pull plate abuts against the lower end of the suppression end, suppressing the anti-lock lock core from rotating to the anti-lock position.

[0023] The present invention is further configured such that: the installation cavity opens toward the lock body, a sealing plate is provided at the opening, and a moving groove for the core rod to move back and forth is formed on the sealing plate.

[0024] The sealing plate can protect the components in the installation cavity. Although it is also possible to seal directly with the door panel without the sealing plate, it is easy for parts to scatter during transportation and installation.

[0025] The present invention is further configured as follows: spring grooves are formed on the left and right sides of the installation cavity, the front end of the spring groove is the positioning end of the return spring, the unlocking sliding block extends a return end toward the spring groove, the front end of the return spring abuts against the positioning end of the return spring, and the rear end of the return spring abuts against the return end.

[0026] The above arrangement makes the space layout more reasonable and the space utilization rate higher. Moreover, the positioning block can prevent the unlocking slide block from moving upward too far, and the upward movement distance of the unlocking slide block can be set as needed.

[0027] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: no matter whether the door is unlocked from inside or outside, it is only necessary to push the pressing portion forward to move the unlocking slide block forward. Since a core rod is connected between the two unlocking slide blocks, the forward movement of one unlocking slide block will drive the core rod and the other unlocking slide block forward together. Furthermore, since the core rod passes through the core groove of the straight-push square core plate, the straight-push square core plate will also move forward when the core rod moves forward. The straight-push end on the straight-push square core plate drives the linkage end of the toggle plate to move, thereby rotating the toggle plate. The toggle end of the toggle plate rotates in the toggle groove, driving the lock tongue pull plate to move backward, causing the magnetic lock tongue to retract into the lock shell, thereby completing the unlocking. Therefore, the device can achieve direct-push unlocking by directly pushing the pressing portion on the handle in conjunction with the straight-push square core plate on the lock body, even when a fixed handle is used, even if a smart lock is not used.

DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0044] A novel unlocking structure includes two handles 20 and a lock body 1 disposed between the two handles: The lock body 1 includes a lock shell 2, a magnetic lock tongue 3 is provided in the lock shell, a lock tongue hole is formed at the front end of the lock shell for the magnetic lock tongue 3 to extend, and a lock tongue pull plate 4 is connected to the rear end of the magnetic lock tongue 3, and a toggle plate 6 is formed on the lock tongue pull plate 4. A toggle groove 5 is formed, and a toggle plate 6 is further provided at the rear of the magnetic lock tongue 3. The toggle plate 6 is rotatably connected to the lock shell, and the toggle plate 6 extends a toggle end 7 toward the toggle groove, and the toggle end 7 is arranged in the toggle groove 5; a straight-push square core plate 8 is provided at the rear of the toggle plate 6, and the straight-push square core plate 8 moves back and forth in the lock shell, and a core groove 9 is formed on the straight-push square core plate 8, and the lock shell is formed with a transverse groove 10 corresponding to the core groove 9, and the straight-push square core plate extends a straight-push end 11 toward the front, and the toggle plate is provided with a linkage end 12 corresponding to the straight-push end; The two handles 20 each include a handle housing 21, on which a mounting cavity 22 is formed. The two mounting cavities 22 are arranged opposite to each other, and an unlocking sliding block 23 is arranged in the mounting cavity 22. The unlocking sliding block 23 can slide back and forth in the mounting cavity 22, and a through slot 24 is provided at the rear end of the mounting cavity. The rear end of the unlocking sliding block 23 extends backward to form a through slot to form a pressing portion 25; a limiting portion 26 is also provided in the mounting cavity 22, and the unlocking sliding block is formed with a limiting end 27 matching the limiting portion. The limiting portion 26 is arranged behind the limiting end 27. A return spring 28 is also provided in the mounting cavity 22, and a return spring positioning end 29 is provided in the mounting cavity. One end of the return spring 28 is connected to the return spring positioning end 29, and the other end of the return spring 28 is connected to the unlocking sliding block 23. The return spring 28 always gives the unlocking sliding block 23 a force to move backward, so that the limiting end 27 of the unlocking sliding block 23 rests on the limiting portion 26; A core rod 30 is connected between the two unlocking sliding blocks 23. The core rod 30 passes through the core groove 9 of the straight-push square core plate 8. The unlocking sliding block 23 moves back and forth, driving the core rod 30 to move back and forth and driving the straight-push square core plate 8 to move back and forth. The straight-push end 11 of the straight-push square core plate 8 drives the linkage end 12 of the toggle plate 6 to move, thereby rotating the toggle plate 6. The toggle end 7 of the toggle plate 6 rotates in the toggle groove 5, driving the lock tongue pull plate 4 to move backward, so that the magnetic lock tongue 3 is retracted into the lock shell 2.

[0045] The bolt pull plate 4 is arranged below the toggle plate 6, the toggle plate 6 extends downwardly out of a toggle end 5, and the toggle end 7 extends downwardly into the toggle groove 5 of the bolt pull plate 4. The linkage end 12 is arranged above the toggle plate 6, and the upper end of the straight-push square core plate 8 extends forward out of a straight-push end 11. The straight-push square core plate 8 moves forward to drive the linkage end 12 forward, and the toggle plate 6 rotates accordingly, causing the toggle end to move backward with the pull plate to retract the magnetic bolt 3 into the lock housing. Through the above arrangement, the bolt pull plate 4 is arranged below, the straight-push end 11 is arranged above, and the toggle plate 6 is arranged in the middle, which can maximize the space utilization of the installation slot in the lock housing, thereby reducing the size of the lock body.

[0046] The lock housing is a rectangular structure, and a rectangular mounting slot 13 is formed in the lock housing. The width of the magnetic lock tongue 3 is the same as the mounting slot 13, and the straight-push square core plate 8 is the same as the mounting slot 13. Through the above arrangement, the lock tongue is the same width as the lock housing mounting slot, and the straight-push square core plate is also the same width as the mounting slot 13, so no additional guide parts are required, which reduces the number of guide parts, can reduce the size of the lock housing, and reduce costs. In addition, fewer parts can make the structure more stable.

[0047] A tension spring column 14 is formed in the lock housing 2, to which a tension spring 15 is connected. The other end of the tension spring 15 is connected to the magnetic lock tongue 2. The tension spring 15 constantly applies force to retract the magnetic lock tongue 3 into the lock housing. The provision of the tension spring 15 prevents the magnetic lock tongue from swinging out of the lock housing when the lock is unlocked, thereby preventing scratches and other damage.

[0048] The lock housing is further formed with a limit block 16, and a guide gap is formed between the limit block 16 and the lower wall of the lock housing. The lock tongue pull plate 4 is disposed in the guide gap. A positioning lug 17 is further formed on the lock tongue pull plate 4, and the lock housing is further formed with a positioning block 18 corresponding to the positioning lug 17. The positioning lug 18 is disposed between the limit block 16 and the positioning block 18. The above arrangement can guide the lock tongue pull plate 4, making the movement of the lock tongue pull plate 4 more stable, thereby indirectly making the movement of the magnetic lock tongue more stable. The arrangement of the positioning lug 17 can limit the distance that the lock tongue pull plate can extend and retract, thereby limiting the distance that the magnetic lock tongue can extend and retract.

[0049] The straight-pushing square core plate 8 is further provided with a guide boss 19 corresponding to the transverse shift groove. By providing the guide boss 19, the moving range of the straight-pushing square core plate can be limited by the transverse shift groove, and can also play a guiding role.

[0050] A reverse lock cylinder 31 is further provided in front of the straight-pushing square core plate 8, and the reverse lock cylinder 31 is rotatably connected to the lock housing, and a reverse lock end 32 is formed on the reverse lock cylinder 31. By the arrangement of the reverse lock cylinder 31, when the reverse lock end is against the straight-pushing square core plate 8, reverse locking can be achieved.

[0051] The mounting cavities 22 of the two handle housings are each provided with a rotation slot 33, and a rotation member is provided in each rotation slot 33. A reverse locking bar 34 is connected between the two rotation members. The reverse locking bar 34 passes through the reverse locking cylinder 31. The rotation of the rotation member drives the reverse locking bar 34 and the reverse locking cylinder 31 to rotate. With the above arrangement, the reverse locking bar 34 can be controlled by the rotation member, thereby rotating the reverse locking cylinder 31 to achieve reverse locking.

[0052] The rotating member of one handle is a knob 35, and the rotating member of the other handle is a key core 36. The outer ends of the knob 35 and the outer ends of the key core 36 are both connected to the outside of the corresponding handle housing. Preferably, the outside handle uses the key core 36, and the door can be locked from the outside using the key core 36 of the outside handle. The inside handle uses the knob 35, and the door can be locked from the inside using the knob 35 of the inside handle.

[0053] The installation cavity 22 opens toward the lock body and is provided with a sealing plate 37 at the opening. The sealing plate 37 is formed with a movable groove 38 for the core rod 30 to move back and forth. The provision of the sealing plate 37 protects the components within the installation cavity. Although it is possible to seal the cavity directly with the door panel without the sealing plate, this can easily cause components to become scattered during transportation and installation.

[0054] The reverse lock cylinder 31 is also formed with an inhibition end 43, which is arranged in front of the reverse lock end 32. When the magnetic lock tongue retracts, the lock tongue pull plate 4 abuts against the lower end of the inhibition end 43, inhibiting the reverse lock cylinder from rotating to the reverse lock position.

[0055] Spring slots 39 are formed on both sides of the mounting cavity 22. The front ends of the spring slots 39 serve as the return spring positioning ends 29. The unlocking slider 23 extends into the spring slots to form a return end 40. The front end of the return spring 28 abuts against the return spring positioning ends 29, while the rear end of the return spring 28 abuts against the return end 40. This arrangement optimizes spatial layout and improves space utilization. Furthermore, the positioning blocks prevent the unlocking slider from moving upward excessively, allowing the desired upward movement distance to be adjusted.

[0056] A positioning portion 41 is further provided between the two spring slots 39 , and the unlocking sliding block 23 forms a positioning end 42 , and the positioning portion 41 is provided in front of the positioning end 42 .

[0057] A spring mounting position is formed on the anti-locking end 32, and a compression spring (not shown) is provided in the spring mounting position. A positioning steel ball (not shown) is connected to the compression spring. The lock housing has two positioning holes corresponding to the steel ball, namely the anti-locking positioning hole 44 and the normal positioning hole 45.

[0058] Working principle: When unlocking, whether inside or outside the door, one only needs to push the pressing portion 25 forward to move the unlocking slide 23 forward. Since a core rod 30 is connected between the two unlocking slides 23, the forward movement of one unlocking slide 23 will drive the core rod 30 and the other unlocking slide 23 forward together. Furthermore, since the core rod 30 passes through the core groove 9 of the straight-push square core plate 8, the forward movement of the core rod 30 will also move the straight-push square core plate 8 forward. The straight-push end 11 on the straight-push square core plate 8 drives the linkage end 12 of the toggle plate to move forward, thereby rotating the toggle plate 6. The toggle end 7 of the toggle plate rotates backward in the toggle groove 5, driving the lock bolt pull plate 4 to move backward, causing the magnetic lock bolt 3 to retract into the lock housing, thus completing the unlocking.

[0059] After unlocking, under the action of the reset spring 28, the reset spring 28 will move the unlocking slide block 23 backward and reset, and at the same time drive the straight-pushing square core plate 8 backward and reset through the core rod 30, which is convenient for the next unlocking.

[0060] When locking the door, the key core 36 can be used to rotate the anti-lock bar 34 outside the door, thereby rotating the anti-lock cylinder 31, so that the anti-lock end 32 of the anti-lock cylinder 31 abuts against the front of the straight-push square core plate 8 to complete the anti-lock. If the door is inside, the knob 35 can be used to rotate the anti-lock bar 34, thereby rotating the anti-lock cylinder 31, so that the anti-lock end 32 of the anti-lock cylinder 31 abuts against the front of the straight-push square core plate 8 to complete the anti-lock.

[0061] The present invention has a simple structure and can realize direct push unlocking by directly pushing the pressing part on the handle in conjunction with the direct push square core plate on the lock body. It can also be unlocked with a fixed handle without using a smart lock.

[0062] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
