Description

Technical Field

[0001] This utility model relates to hotel locks, and more particularly to a mortise lock for hotels. Background Technology

[0002] Currently available smart locks with mortise lock cylinders have complex drive structures. The entire lock body requires multiple parts to operate in tandem, especially the square latch arm, angled latch arm, and key-operated latch arm, which can only control each unit individually. This results in numerous parts and a high failure rate. The handle rotating seat assembly involves small parts such as pins and caps, making assembly complex. The handle rotating seat fork must be differentiated between the inside and outside of the door, and the pin clutch requires a separate idler mechanism for engagement. The lock body's installation direction must be determined before leaving the factory. If the lock body direction needs to be changed in actual use, it must be returned to the factory by a professional. Non-professionals cannot easily change the lock body direction according to their needs.

[0003] Based on the shortcomings of the above-mentioned technologies, it is necessary to study a technology that requires only one main push plate to drive the square latch, oblique latch, and lock cylinder in a coordinated manner. The structural design simplifies the process and enables the door lock to be opened, making installation very convenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model solves the problem of complex structural design in hotel mortise locks. It only requires a main push plate to drive the square bolt, oblique bolt, and lock head in a coordinated manner, resulting in a simpler structural design that achieves the goal of opening the door lock and making installation very convenient.

[0005] A smart lock for hotels with mortise lock cylinders includes a main push plate inside the lock housing.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figures 1 to 9As shown, a smart lock for hotels with mortise locks is provided. The base 21 is fixed to the side plate strip 22 with screws 24. The main push plate 6 is then placed in relation to the base 21. The drive plate 45 hole 451 and the second fixing post 454 are inserted into the drive groove 65 of the main push plate 6. The first fixing post 452 of the drive plate 45 is inserted into the hole 63 of the main push plate 6 and riveted. Next, fix the return spring 33 to the positioning piece 211 of the base 21. Then, insert the lower boss 344 of the crank arm 34 into the main push plate 6 slide groove 64 and fix it to the base 21. The crank arm 34 column 342 is connected to the return spring 33. The linkage column 343 is connected to the first locking position 66 of the main push plate 6. The hanging ear 346 is connected to the first groove 62 of the main push plate 6. Then, fix the square tongue 31 to the tail plate 32 and connect it to the square tongue hole 223 of the side plate strip 22. Then, insert and lock the square tongue 31 tail plate 32 slide groove 321 to the crank arm 34 guide column 341. The tail plate 32 fork groove 322 is inserted into the upper boss 345 of the crank arm 34. The upper boss 345 is provided with a knob hole 347. After inserting and fixing the locking plate 53 into the fixing post 213 of the base 21, the locking tongue 51 is connected to the locking tongue plate 52, with the locking tongue 51 corresponding to the locking tongue hole 225 of the side plate strip 22. The guide groove 521 of the locking tongue plate 52 is inserted into the fixing post 213 of the base 21, and the return spring 54 is inserted into the post 533 of the locking plate 53 and the nail 522 of the locking tongue plate 51. Next, the fixing block 44 hole 443 of the inclined tongue assembly 4 and the corresponding connecting rod 42 of the return spring 43 are passed through and connected to the inclined tongue 41. The inclined tongue 41 is inserted into the inclined tongue hole 224 of the side plate strip 22, and the lower locking position 442 of the fixing block 44 is inserted into the second groove 68 of the main push plate 6 and matches the contact angle 453 of the drive plate 45. Finally, fix the motor 81 and cable bracket 82 of the motor assembly 8 to the base 21, and then fix the fork 72 of the handle rotation assembly 7 to the base 21. Adjust the direction of the fork 72 assembly indicator 724 to align with the cable bracket 82. Install the clutch hook 716 in the inner groove 714 of the rotating seat 71, and attach the return spring 717 to the clutch hook 716 pin 7160. The other end of the return spring 717 is fixed in the outer groove 715 of the rotating seat 71. Place the second fork 72 with the same structure in the through hole 711 of the rotating seat 71. Adjust the fork 72 assembly indicator 724 to align with the cable bracket 82. The clutch hook 716 of the rotating seat 71 corresponds to the push plate 811 of the motor 81. Then, put on the cover plate 23 and lock it with screws 24. Then insert the lock head 9 into the lock head hole corresponding to the base 21, and insert the long screw 222 into the screw hole corresponding to the side plate strip 22. The long screw 222 passes through the hole 210 of the base 21 fixing plate and enters the screw hole 95 of the lock head 9 to lock it. The cam 93 set in the notch 94 of the lock head 9 corresponds to the first top position 61 of the main push plate 6. The key 96 is inserted into the key hole 92. The assembly of the lock body 1 is now complete.Of course, when the product is packaged at the factory, the lock shell 2, lock cylinder 9, and handle square shaft 73 are usually packaged separately. The lock cylinder 9, key 96, long screw 222, and handle square shaft 73 are packaged separately and placed in a large box. Only when the user installs the door lock, the mortise lock shell 2 is aligned with the lock groove on the door frame and inserted. Then the lock cylinder 9 is inserted into the lock hole on the door. The long screw 222 is inserted into the lock cylinder 9 on the side strip 22 to fix it. The handle square shaft 73 is inserted into the rotating seat 71 of the lock shell 2 and the fork 72 shaft hole 723 to fix it.

[0034] Furthermore, such as Figure 2 As shown, the motor assembly 8 cable bracket 82 is equipped with a key switch 821, a square latch switch 822, and a beveled latch switch 823. The key switch 821 records key unlocking. When someone uses key 96 to open the lock, the cam 93 of the lock head 9 contacts the switch, leaving a key unlocking record in the backend. If key 96 remains stationary after opening the lock and contacting the switch for a certain period, the unlocking record can be cleared, restoring factory settings. The square latch switch 822 has a protective plate 824. When the door is deadbolted from the inside, the square latch extends from the lock housing 2, disengaging from the switch. The main board receives a signal and locks, preventing guests outside from opening the door by card or password. The latch switch 823 has a quick return function for the motor 81. When the door lock is opened by swiping a card, the motor 81 runs and engages, the handle opens the door lock, and the second fixing post 454 of the drive plate 45 under the latch assembly 421 contacts the switch. After receiving the signal, the main board quickly reverses the motor 81 to complete the disengagement and return, and the handle cannot be pressed again to open the door lock. This function can prevent tailgating. Without this function, after the motor runs and engages, it usually takes a few seconds to retract and disengage. During this period, the door lock can still be opened by the handle.

[0035] like Figure 2 , Figure 7 and Figure 8 As shown, a smart lock for hotels includes a main push plate 6 inside the lock housing 2. The main push plate 6 is used to drive the lock cylinder 9, square bolt assembly 3, safety bolt assembly 5, bevel bolt assembly 4, handle rotation assembly 7, and motor assembly 8 to unlock. The main push plate 6, located on the base 21 of the lock housing 2, is linked with the lock cylinder 9, square bolt 31, safety bolt 51, bevel bolt 41, and handle rotation seat 71. When the motor 81 rotates, the push plate 811 pops out and collides with the clutch hook 716 of the rotation seat 71, pushing the clutch hook 716 into the clutch slot 72 of the fork plate 72 of the rotation seat 71. This engages the clutch slot 722, causing the handle square shaft 73 to rotate. When the rotating rotation seat 71 pushes the crank arm 712 against the second top position 69 of the main push plate 6, the main push plate 6 starts to operate in conjunction with the lock cylinder 9, achieving the purpose of unlocking.

[0036] The following describes the rotation process of the rotating component during use: (e.g.) Figure 8As shown, the lever fork 72 consists of two pieces of the same structure. One piece is mounted on the base 21 and sleeved onto the rotating seat 71, while the other piece is mounted on the rotating seat 71 and forms the shaft hole 723 for the handle square shaft 73. This creates the shaft holes 723 inside and outside the door. The outside handle square shaft 73 is inserted into the shaft hole 723 of the lever fork 72 in the rotating seat 71 for connection. Since the outside lever fork 72 is not locked with a locking screw, when the outside handle is turned, the square shaft only causes the rotating seat 71 to rotate freely, without engaging the rotating seat 71, thus preventing the door from opening. A door lock signal is required to start the motor, pushing the clutch hook 716 into the clutch slot 72 to engage the lever fork 72 with the rotating seat 71, thereby unlocking the door. The door handle square shaft 73 is inserted into the shaft hole 723 of the shift fork 72 for connection. The shift fork 72 is locked in the locking slot 721 of the door handle by the shift fork locking screw 718. Therefore, when the door handle is turned, the handle square shaft 73 can drive the shift fork 72 to rotate the seat 71 in conjunction with it, thus opening the door lock.

[0037] Furthermore, such as Figures 1 to 7 It also includes Figure 7-1 Driver board structure diagram, and Figure 9 As shown, the first top position 61 of the main push plate 6 matches the cam 92 of the lock head 9, the slide groove 64 is inserted into the lower boss 344 of the square tongue crank arm 34, the drive groove 65 is inserted into the second fixing post 454 of the drive plate 45, and the first fixing post 454 of the drive plate 45 is inserted into the hole 63 of the main push plate 6. The first locking position 66 of the main push plate 6 matches the linkage post 343 of the square tongue crank arm 34, and the second locking position 67 matches the contact angle 532 of the safety lock plate 53; the contact angle 453 of the drive plate 45 matches the locking position 421 of the connecting rod 42 of the oblique tongue assembly 4; the second groove 68 of the main push plate 6 locks the lower locking position 442 of the fixing block 44 of the oblique tongue assembly 4; the second top position 69 of the main push plate 6 matches the crank arm 712 of the handle rotating seat 71, and the clutch hook 716 of the handle rotating seat 71 matches the push plate 811 of the motor 81 to form a linkage unlocking. The lower boss 344 of the square tongue 31 crank arm 34 is inserted into the slide groove 64 of the main push plate 6. The hanging ear 346 corresponds to the first groove 62 of the main push plate 6. The linkage column 343 corresponds to the first locking position 66 of the main push plate 6. The positioning piece 211 of the base 21 is connected to the reset spring 33. The guide column 341 is inserted into the slide groove 321 of the tail plate 32 of the square tongue 31. The base 21 is provided with a safety tongue assembly 5. The safety tongue plate 52 and the safety lock plate 53 are sleeved with the reset spring 54, and the contact angle 532 of the safety lock plate 53 matches the second locking position 67 of the main push plate 6. The oblique tongue assembly 4 is provided with a fixing block 44. The fixing block 44 is provided with a hole 443, an upper locking position 441 and a lower locking position 442. When the fixing block 44 and the reset spring 43 are sleeved with the connecting rod 42 and the lower locking position 442 is inserted into the second groove 68 of the main push plate 6 to form a locking position 421, the locking position 421 is connected to the contact angle 453 of the drive plate 45.

[0038] Further, let's describe the main push plate driving principle in detail. When the door is closed (in hotel door locks, the door strike plate typically only has a bevel bolt hole and a square bolt hole), after the bevel bolt 41 and the safety bolt 51 retract into the lock housing 2, when they extend into the door strike plate again, the safety bolt 51 is blocked by the door strike plate and no longer pops out. When the protrusion 523 on the safety bolt plate 52 slides down to the wave position 534 of the safety lock plate 53, under the force of the return spring 54 of the safety bolt 52, the safety lock plate 53 deflects towards the bevel bolt 41. At this time, if the bevel bolt 41 is pushed back by an external force or pressed, it will be blocked by the safety bolt plate 52 and cannot completely exit the door strike plate, thus achieving an anti-push function. At the same time, the square bolt crank arm 34 can be rotated by the door lock knob inside the door. The guide post 341 on the square bolt crank arm 34 drives the square bolt 31 to push out of the door strike plate through the slide groove 321 on the tail plate 32 of the square bolt 31, completing the locking of the square bolt 31.

[0039] like Figure 8 As shown, the handle rotation assembly 7 has a rotating seat 71 that houses a clutch hook 716 and a shift fork 72. The rotating seat 71 has a through hole 711 inside and a crank arm 712 outside. The through hole 711 has an inner groove 714 that houses the clutch hook 716. A return spring 717 is fitted onto the pin 7160 of the clutch hook 716 and secured to the outer groove 715 of the rotating seat 71. The shift fork 72 has a locking groove 721 and a clutch groove 722 on the outside and a shaft hole 723 and an assembly indicator 724 inside. The handle square shaft 73 is divided into an outer and an inner part. After the shift fork 72 is installed in the rotating seat 71, the handle square shaft 73 is inserted into the shaft hole 723 corresponding to the shaft hole 723.

[0040] Based on the above embodiments, the process of motor unlocking and key unlocking is explained below: The motor 81 rotates, pushing out the push plate 811, which in turn pushes the clutch hook 716 into the clutch slot 722 of the fork plate 72 of the rotating seat 71, completing the engagement between the rotating seat 71 and the fork plate 72. The handle square shaft 73 is then turned to rotate the entire rotating assembly. The rotating seat 71, via the crank arm 712, rotates to the second top position 69 of the main push plate 6, causing the main push plate 6 to begin operation. During operation, the drive plate 45 on the main push plate 6 drives the second fixed column 452, causing the drive plate 45 to rotate inward. The drive plate 45's contact point 453 pulls the inclined tongue 41 back, completing the retraction of the inclined tongue 41. Simultaneously, the retraction of the inclined tongue 41 drives the safety tongue plate 52, pulling the safety tongue 51 back as well. During operation, the main push plate 6 will also cause the first top position 66 of the main push plate 6 on the square tongue crank arm 34 to collide with the linkage column 343, pulling the square tongue 31 back and completing the entire unlocking process. If unlocking with a key, insert the key 96 into the keyhole 92 of the lock cylinder 9, turn the key 96, and the cam 93 of the lock cylinder 91 inside the lock cylinder 9 will begin to rotate, linking the first top position 61 of the main push plate 6 and pulling the main push plate 6 to start running. At this time, during the operation of the main push plate 6, the drive plate 45 on the main push plate 6 will drive the second fixed column 452, causing the drive plate 45 to rotate inward. The contact angle 453 of the drive plate 45 will drive the oblique tongue 41 back, completing the oblique tongue 41 retraction. The oblique tongue 41 retraction simultaneously drives the safety tongue plate 52, pulling the safety tongue 51 back as well. During the operation of the main push plate 6, the first top position 66 of the main push plate 6 on the square tongue crank arm 34 will also collide with the linkage column 343, pulling the square tongue 31 back and completing the entire unlocking process.

[0041] Although the present invention has been described in detail through the above embodiments, those skilled in the art should understand that various changes can be made to it in form and detail, but without departing from the scope defined by the claims of the present invention, and are also within the scope of protection.
