Description

Technical Field

[0001] This utility model relates to a door lock body for use in hotels. Background Technology

[0002] Currently, most hotel room door locks, even when the latch is not extended (because hotel guests forget to operate the handle to lock the latch when leaving), can still be opened by pushing the bolt out of the bolt hole on the door frame with a thin, hard piece of material, such as a card or ID card, as long as the gap at the lock is large enough to insert such a piece. This is because there is no special structure to prevent people from pushing the bolt with a thin, hard piece of material. Therefore, most new hotel locks still need improvement in terms of anti-theft performance. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of hotel lock body with a reasonable structure, higher anti-theft performance and longer service life.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0005] A novel hotel lock body includes a lock shell, a motor assembly, a latch assembly, a bolt assembly, a safety latch assembly, a square bolt assembly, and a bolt actuation assembly, wherein:

[0006] The motor assembly includes a motor, a motor drive component, a locking pin, and a locking pin return spring; the locking pin and the locking pin return spring are disposed within the jack assembly.

[0007] The mortise assembly includes an outer mortise connected to the outer handle and an inner mortise connected to the inner handle; the outer mortise is located in the inner mortise; when the motor is not working, the outer mortise and the inner mortise can rotate independently, and when the unlocking pin is pushed into the mortise assembly by the motor drive unit driven by the motor, the outer mortise can be rotated to unlock.

[0008] The tongue assembly includes a tongue, a tongue rod, and a tongue return spring;

[0009] The locking latch assembly includes a locking latch, a locking latch connecting piece, a locking latch return spring, a bevel locking piece, a square locking piece, and a locking piece return torsion spring. The length of the locking latch protruding from the lock housing in the reset state is shorter than that of the bevel locking piece. A bevel guide platform and a square locking piece push post are provided on the locking latch connecting piece. After the bevel locking piece and the square locking piece are swung into the lock housing, the guide post on the bevel locking piece can slide along the bevel guide platform and swing towards the locking latch connecting piece under the action of the locking piece return torsion spring. Meanwhile, the square locking piece overcomes the torsion of the locking piece return torsion spring under the pushing force of the square locking piece push post. The force causes the latch plate to swing towards the square latch assembly; the inclined latch safety plate has a downward pressing and pushing inclined surface on the upper part of the end facing the vertical end face of the inclined latch; in the unlocked state, the guide post on the inclined latch safety plate contacts the inclined guide surface at the lower position of the inclined guide platform, while the higher end of the inclined guide platform faces the vertical end face of the inclined latch; in the closed state, the outer end face of the safety latch rests on the plane of the door strike plate, causing the safety latch to retract slightly into the lock housing; under the pushing action of the vertical end face of the inclined latch, the safety latch can overcome the force of the safety latch return torsion spring and generate a tendency to swing towards the direction of the safety latch connecting piece;

[0010] The square tongue assembly includes a square tongue, a square tongue plate, and a square tongue retraction spring; the square tongue plate is provided with a square tongue blocking position that can be blocked by the square tongue safety plate when the door is open.

[0011] The latch actuation assembly includes a slider, a latch lever, and a latch lever block stacked from bottom to top in the lock housing; the slider can slide vertically in the lock housing; on one or both sides of the upper end of the slider, there is a force-receiving part that contacts one or both sides of the inner latch and allows the slider to slide downward under the action of the inner latch; on both sides of the lower part, there are lever pushing parts and lever pushing parts; on the upper part of the latch lever, there is a latch pushing part that can push the latch assembly inward; on both sides of the lower part, there are lever force-receiving parts that contact the lever pushing part and latch unlocking parts that release the latch safety plate from locking the latch plate; the upper end of the latch lever block is provided with a knob mounting seat that connects to a knob on the lock body; on the left side, there is a latch push-pull post that falls into the inclined slot hole on the latch plate for pushing and pushing the latch assembly; and in the middle, there is a lever force-receiving post that contacts the lever pushing part.

[0012] In the improved version of the above-mentioned novel hotel lock body, the lock shell is provided with separate lock holes above and below the square rod hole of the jack assembly.

[0013] In the above-mentioned improved solution of a new type of hotel lock body, there are two force-bearing parts at the upper end of the slider, which are located on both sides of the upper end of the slider and in contact with the two sides of the inner pusher.

[0014] In the improved solution of the above-mentioned new hotel lock body, the outer pin is provided with four lock pin insertion holes for the unlocking pin to be inserted, and these four lock pin insertion holes are evenly distributed on a 360-degree circumference.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A safety latch assembly is provided inside the lock housing, comprising a safety latch, a safety latch connecting piece, a safety latch return spring, a beveled safety latch piece, a square safety latch piece, and a safety latch return torsion spring; the length of the safety latch protruding from the lock housing in the reset state is shorter than that of the beveled latch; and a safety latch plate is provided for use when the door is open (not closed). The square latch, when in its locked position, is restrained by the locking mechanism of the square latch safety piece. This prevents the square latch from being intentionally or unintentionally pulled out by the deadbolt knob connected to the latch lever when the door is not closed. We know that if the square latch is extended when the door is open, it is easy to damage the square latch or the door frame. Therefore, this invention has a reasonable structure and a longer service life. Furthermore, under the action of the safety piece return spring, the guide post on the oblique latch safety piece slides upward along the oblique guide platform on the safety latch connecting piece. The oblique latch safety piece then swings slightly in the oblique latch direction. This allows the outermost end of the oblique latch safety piece to face the vertical end face of the oblique latch. In this case, if the square latch is not extended to lock the door, and a criminal attempts to push the oblique latch by inserting a thin, hard object such as a card or ID card into the door gap, the slightly retracted vertical end face of the oblique latch will be blocked by the outermost end of the oblique latch safety piece, preventing the oblique latch from being pushed to open the door. Therefore, this invention improves the anti-theft performance of hotel room door locks.

[0024] This utility model is a novel hotel lock body, such as Figures 1 to 7 As shown, it includes a lock housing 1, a motor assembly 2, a latch assembly 3, a bolt assembly 4, a safety latch assembly 5, a square latch assembly 6, and a latch drive assembly 7, wherein:

[0025] The motor assembly 2 includes a motor 21, a motor drive component 22, a locking pin 23, and a locking pin return spring (not shown in the figure); the locking pin 23 and the locking pin return spring are disposed within the jack assembly 3.

[0026] The door unlocking assembly 3 includes an outer door unlocking 31 connected to the outer handle and an inner door unlocking 32 connected to the inner handle; the outer door unlocking 31 is located in the inner door unlocking 32; when the motor 21 is not working, the outer door unlocking 31 and the inner door unlocking 32 can rotate independently, and the inner door unlocking 32 can rotate independently for quick escape and unlocking, while the outer door unlocking 31 is in a 360-degree free state when it fails to unlock correctly. When the unlocking pin 23 is pushed into the door unlocking assembly 3 by the motor drive component 22 driven by the motor 21, the outer door unlocking 31 can be rotated to unlock. This means that after swiping the room card or entering the correct password to make the motor work, you can press down the outer handle from the outside of the door to open the door;

[0027] The oblique tongue assembly 4 includes an oblique tongue 41, an oblique tongue rod 42, and an oblique tongue return spring 43;

[0028] The locking latch assembly 5 includes a locking latch 51, a locking latch connecting piece 52, a locking latch return spring 53, a beveled locking piece 54, a square locking piece 55, and a locking piece return torsion spring 56; the length of the locking latch 51 exposed above the lock housing 1 in the reset state is shorter than that of the beveled locking piece 41, such as... Figure 2As shown; the latch connecting piece 52 is provided with an inclined guide platform 521 and a square latch safety plate push post 522; after the inclined latch safety plate 54 and the square latch safety plate 55 are swung into the lock housing 1, the guide post 541 on the inclined latch safety plate 54 can slide along the inclined guide surface 5211 of the inclined guide platform 521, and swing towards the latch connecting piece 52 under the action of the safety plate return torsion spring 56, while the square latch safety plate 55, under the pushing force of the square latch safety plate push post 522, overcomes the torsion of the safety plate return torsion spring 56 and swings towards the square latch plate of the square latch assembly 6. 62; The inclined latch safety plate 54 has a force-receiving downward pushing inclined surface 542 on the upper part of the end facing the vertical end face 411 of the inclined latch; In the unlocked state, the guide post 541 on the inclined latch safety plate 54 contacts the inclined guide surface 5211 at the lower position of the inclined guide platform 521, while the higher end of the inclined guide platform 521 faces the vertical end face 411 of the inclined latch 41; The door strike plate on the door frame corresponding to the safety latch 51 does not need to be excavated with a safety latch receiving hole but has an inclined latch hole, and the safety latch 51 freely presses against the plane of the door strike plate according to the door gap, and is always in the safe state. Therefore, when the door is closed, the outer end face of the locking tongue 51 rests against the flat surface of the door's door latch plate, causing the locking tongue to retract slightly into the lock housing; under the pushing action of the vertical end face 411 of the latch 41, the latch locking piece 54 can overcome the force of the locking tongue return torsion spring 56 and generate a tendency to swing in the direction of the locking tongue connecting piece 52, so as not to hinder the opening of the latch.

[0029] The square tongue assembly 6 includes a square tongue 61, a square tongue plate 62, and a square tongue retraction spring 63. The square tongue plate 62 is provided with a square tongue blocking position 621 that can be blocked by the locking position 551 of the square tongue safety piece 55 when the door is open. In this way, when the door is not closed, it can prevent people from intentionally or unintentionally turning the deadbolt knob connected to the lock tongue lever to pull out the square tongue 61. We know that once the square tongue is extended when the door is open, it is easy to cause the square tongue or door frame to be damaged by collision.

[0030] The latch actuating assembly 7 includes a slider 71, a latch lever 72, and a latch lever block 73, which are stacked from bottom to top in the lock housing 1. The slider 71 can slide vertically in the lock housing 1. A force-receiving part 711 is provided on one or both sides of the upper end of the slider 71, which contacts one or both sides of the inner latch 32 and allows the slider 71 to slide downwards under the action of the inner latch 32. A lever pushing part 712 and a lever pushing part 713 are provided on both sides of the lower part. Above the latch lever 72 is a latch pushing part 721 that can push the latch assembly 4 inwards. A latch pushing part 721 is provided on both sides of the lower part. The lever force-receiving part 722 is in contact with the lever push part 712 and the latch lock unlocking part 723 is used to release the latch lock 54 from locking the latch plate 62; the upper end of the latch lever 73 is provided with a knob mounting seat 731 connected to the knob on the lock body (not shown in the figure, which is on the inner panel of the door lock for guests in the hotel room to turn the knob to lock); the left side is provided with a latch push-pull post 732 in the inclined slot hole 622 on the latch plate 62 for pushing and pulling the latch assembly 6; and the middle part is provided with a lever force-receiving post 733 in contact with the lever push part 713.

[0031] like Figure 2 , 4 As shown in Figure 5, multiple detection switches 8 are provided inside the lock housing 1 to detect the status of the latch, bolt, lock cylinder, and motor feedback when the door is opened. Their working principles are commonly used in hotel room systems and will not be described in detail here.

[0032] The working process of this utility model is mainly as follows:

[0033] 1. When the door needs to be opened while it is locked, swipe the room card or enter the correct password. Motor 21 will then drive the unlocking pin 23 into the unlocking assembly 3, putting the outer unlocking pin 31 into a rotatable unlocking state. This allows the door to be opened from the outside by pressing down the outer handle. After the outer handle rotates the unlocking assembly 3, the unlocking assembly 3 causes the slider 71 to slide downwards. Then:

[0034] On one hand, the pusher 712 on the slider 71 acts on the force-receiving part 722 of the latch lever 72, causing the latch lever 72 to rotate. In this way, the latch lever pusher 721 can pull the latch lever assembly 4 to open the latch lever 41. When the latch lever 41 first slides inward a small distance (about 2-3mm), the vertical end face 411 of the latch lever 41 acts on the inclined guide platform 521 of the latch connecting piece 52. In this way, the latch connecting piece 52 can be pushed inward, thereby causing the latch lever 51 to retract into the lock housing. At this time, the inclined guide platform 521 on the latch connecting piece 52 releases the pushing action on the guide post 541 on the latch latch safety piece 54. Then, under the action of the latch reset spring 56, the latch latch safety piece 54 swings slightly in the direction of the latch connecting piece 52. In this way, the latch latch safety piece 54 will not hinder the latch lever 41 from continuing to slide into the lock housing, and thus the latch lever can be opened smoothly.

[0035] On the other hand, the pusher 713 on the slider 71 acts on the pusher force column 733 of the latch block 73, causing the latch block 73 to rotate. In this way, the square tongue push-pull column 732 on the latch block 73 can slide along the inclined slot 622 of the square tongue plate 62, while pulling the square tongue plate 6 and the square tongue 61 connected to the square tongue plate 62 into the lock case 1 to open the square tongue. After the latch is opened, the latch safety piece 55, under the action of the latch safety piece push post 522 on the latch 51, overcomes the force of the latch return spring 56 and swings towards the latch plate 62. In this way, the locking position 551 of the latch safety piece 55 presses against the latch blocking position 621 of the latch plate 52. This prevents the latch from being pushed out by the user when the door is open, whether intentionally or unintentionally. This prevents the latch from being pushed out when the door is open, thus avoiding damage to the latch, door frame, or even the latch itself, thereby improving the service life of the door lock body.

[0036] After doing this, the door was opened.

[0037] 2. When locking the door, simply close the door. At this time, the latch 41 first touches the door frame strike plate, and then the safety latch 51 touches the door frame strike plate. The latch then slides into the lock housing. The vertical end face 411 of the latch 41 touches the outer end face of the inclined guide plate 521 of the safety latch connecting piece 52, causing the safety latch to retract slightly. Under the action of the safety latch return spring 56, the latch safety piece 54 swings slightly towards the safety latch connecting piece 52, preventing it from obstructing the latch from continuing to move inward until it is fully retracted into the lock housing, thus closing the door smoothly. After the door is closed, the latch assembly 4 automatically resets, and the latch 41 slides into the latch hole of the door frame strike plate. The safety latch 51 protrudes slightly (depending on the size of the door gap) and freely presses against the door frame strike plate surface, thus remaining in a safe state. In this way, the safety latch 51 and the safety latch connecting piece 52 retract a small section into the lock housing. At this point:

[0038] On the one hand, under the action of the latch return spring 56, the guide post 541 on the latch lock 54 slides upward along the inclined guide platform 521 on the latch connecting piece 52. Then, the latch lock 54 swings slightly towards the latch 41. In this way, the outermost end of the latch lock 54 can be directly facing the vertical end face 411 of the latch 41. In this case, if the guest does not operate the knob to push out the latch to lock the door, and criminals attempt to push the latch by inserting thin hard pieces such as cards or ID cards into the door gap at an angle, the vertical end face 411 of the slightly retracted latch 41 will be blocked by the outermost end of the latch lock 51. Therefore, the vertical end face 411 of the latch 41 cannot act on the inclined surface 542 of the latch lock 54 under the force, thus limiting the latch assembly 4 from being opened even under illegal external force. Therefore, the anti-theft performance of the hotel room door lock is improved.

[0039] On the other hand, the push post 522 of the square tongue safety piece on the safety tongue connecting piece 52 releases the push of the square tongue safety piece 55. At this time, the square tongue safety piece 55 swings under the action of the safety piece return spring 56, causing the locking position 551 of the square tongue safety piece 55 to move away from the square tongue blocking position 621 of the square tongue plate 62. Then, the inner or outer handle, or the deadbolt knob (operated by the person inside the room) can be operated to push out the square tongue to lock the door.

[0040] As can be seen from the above, the structure of this utility model is more reasonable, which can improve the anti-theft performance and service life of hotel door locks.

[0041] In this embodiment, the lock housing 1 is provided with separate lock holes 11 above and below the square rod hole 33 of the jack assembly 3, for installing the panel of the separate lock. In this way, the present invention can install both an integrated lock panel and a separate lock panel (making the whole lock more concise and stylish), thereby improving the applicable places (scope) of the present invention.

[0042] In this embodiment, there are two force-bearing parts 711 at the upper end of the slider 71, which are located on both sides of the upper end of the slider and contact the two sides of the inner pusher. In this way, the lock body can be operated by pressing down the handle to operate the lock tongue to drive the component 7 to unlock, whether it is installed upright or upside down, thereby improving the application requirements of this utility model.

[0043] In this embodiment, as Figure 6As shown, the outer pusher 31 has four locking pin insertion holes 311 for the unlocking pin 23 to be inserted. These four locking pin insertion holes 311 are evenly distributed on a 360-degree circumference, so there is no need to distinguish the direction when installing the handle square bar, thus avoiding incorrect installation and allowing for faster installation of the square bar. When the unlocking pin 23 is inserted into one of the locking pin insertion holes 311, the inner and outer pushers form a rotating whole, allowing the door to be opened more quickly from the outside.
