Abstract

A novel hotel lock body includes a lock shell, a motor assembly, a latch assembly, a bolt assembly, a safety latch assembly, a square latch assembly, and a latch drive assembly. Because a safety latch assembly is provided within the lock shell, it includes a safety latch, a safety latch connecting piece, a safety latch return spring, a bolt safety piece, a square latch safety piece, and a safety piece return torsion spring; the length of the safety latch protruding from the lock shell in the reset state is shorter than that of the bolt; a square latch stop is provided on the square latch plate, which is restrained by the square latch safety piece when the door is open (not closed). This prevents intentional or unintentional rotation of the deadbolt knob connected to the latch latch lever to extend the square latch when the door is not closed. We know that once the square latch is extended in the open state, it is easy to collide and damage the square latch or the door frame. Therefore, this utility model has a reasonable structure, a longer service life, and improves the anti-theft performance of hotel room door locks.

The working process of the utility model is mainly as follows:

1. When the door is locked and the door is required to be opened, a house card is swiped or a correct password is input, the motor 21 drives the operation to push the unlocking pin 23 into the peach pulling assembly 3, so that the outer peach pulling 31 is in a state of being rotatably unlocked, and thus, the door can be opened by pressing the outer handle downwards, after the outer handle rotates the peach pulling assembly 3, the peach pulling assembly 3 further enables the sliding block 71 to slide downwards, and then:

On the one hand, the pulling piece pushing part 712 on the sliding block 71 acts on the pulling piece force-bearing part 722 of the inclined tongue pulling piece 72 to enable the inclined tongue pulling piece 72 to rotate, so that the inclined tongue component 4 can be pulled by the inclined tongue pushing part 721 to open the inclined tongue 41, when the inclined tongue 41 just begins to slide inwards for a small section (about 2-3 mm), the vertical end face 411 of the inclined tongue 41 acts on the inclined guide table 521 of the safety tongue connecting piece 52, so that the safety tongue connecting piece 52 can be pushed to slide inwards to drive the safety tongue 51 to shrink inwards of the lock shell, at the moment, the inclined guide table 521 on the safety tongue connecting piece 52 releases the pushing action on the guide pillar 541 on the inclined tongue safety piece 54, and then under the action of the safety tongue reset spring 56, the inclined tongue safety piece 54 swings slightly towards the direction of the safety tongue connecting piece 52, so that the inclined tongue 41 is not blocked from sliding inwards continuously, and the inclined tongue can be opened smoothly;

On the other hand, the block pushing portion 713 of the slider 71 acts on the block receiving post 733 of the block 73 to rotate the block 73, so that the tongue push-pull post 732 of the block 73 slides along the inclined slot 622 of the tongue plate 62, and pulls the tongue plate 6 and the tongue 61 connected to the tongue plate 62 into the lock case 1 to open the tongue. After the square tongue is opened, the square tongue safety piece 55 swings to the square tongue plate 62 after overcoming the acting force of the safety tongue reset spring 56 under the action of the square tongue safety piece push column 522 on the safety tongue 51, so that the clamping position 551 of the square tongue safety piece 55 is propped against the Fang Shezu clamping position 621 of the square tongue plate 52, and when in a door opening state, the square tongue can be prevented from being pulled out by manually or unintentionally rotating an anti-lock knob connected with a lock tongue pulling block, so that the square tongue can be prevented from being pushed out when in the door opening state, and the conditions of damaging or touching a square tongue, a door frame and even touching the square tongue can not occur, thereby prolonging the service life of a door lock body.

After such operation, the door is opened.

2. When the door is to be locked, the door is closed, at this time, the latch 41 firstly touches the door frame buckle plate, the safety tongue 51 then touches the door frame buckle plate, then the latch slides into the lock shell, the vertical end face 411 of the latch 41 touches the outer end face of the inclined guide table 521 of the safety tongue connecting piece 52, so that the latch is driven to retract slightly, the latch safety piece 54 swings slightly towards the direction of the safety tongue connecting piece 52 under the action of the safety piece reset spring 56, and the latch safety piece 54 can avoid obstructing the latch from moving inwards until the lock shell is completely retracted, thereby closing the door smoothly. After closing the door, the latch bolt assembly 4 automatically resets, the latch bolt 41 slides into the latch bolt hole of the door frame buckle plate, and the safety bolt 51 freely abuts against the plane of the door buckle plate after exposing a point (according to the size of the door gap), so that the safety bolt 51 and the safety bolt connecting piece 52 are always in a safety state, and thus, the safety bolt 51 and the safety bolt connecting piece 52 retract a small section into the lock shell, and at the moment:

On the one hand, after the guide post 541 on the latch safety piece 54 slides upwards along the inclined guide table 521 on the latch connecting piece 52 under the action of the safety piece reset spring 56, the latch safety piece 54 swings slightly to a small angle towards the latch 41, so that the outermost end of the latch safety piece 54 can be opposite to the vertical end face 411 of the latch 41, in this case, if the tenant does not operate the knob to push out the latch to lock the door, when an illegal molecule attempts to push the inclined tongue by obliquely inserting a thin hard sheet such as a card or an identity card into a door slot, the vertical end face 411 of the inclined tongue 41 which is slightly retracted is blocked by the outermost end of the inclined tongue safety sheet 51, so that the vertical end face 411 of the inclined tongue 41 cannot act on the forced downward pushing inclined face 542 of the inclined tongue safety sheet 54, and the inclined tongue component 4 cannot be opened even under the action of illegal external force is limited, and therefore, the anti-theft performance of a hotel room door lock is improved;

On the other hand, the tongue safety tab pushing post 522 on the safety tab connecting piece 52 releases the pushing of the tongue safety tab 55, at this time, the tongue safety tab 55 swings under the action of the safety tab reset spring 56, so that the clamping position 551 of the tongue safety tab 55 swings away from the Fang Shezu clamping position 621 of the tongue plate 62, and thus, the inner or outer handle can be operated, or the reverse locking knob (operated by a person in a house) can push out the tongue to lock the door.

From the above, the structure of the utility model is more reasonable, and the anti-theft performance and the service life of the hotel door lock can be improved.

In this embodiment, the lock case 1 is provided with split lock holes 11 above and below the square rod hole 33 of the peach pulling component 3, for installing the panel of the split lock, so that the utility model can install both an integral lock panel and a split lock panel (so that the integral lock is more concise and fashionable), thereby improving the applicable place (range) of the utility model.

In this embodiment, the force-bearing parts 711 at the upper end of the sliding block 71 are located at two sides of the upper end of the sliding block and contact with two sides of the inner dial, so that the lock body can be used for pressing down the handle to operate the lock tongue driving assembly 7 to unlock when being assembled or inverted, thereby improving the requirements of the application occasions of the utility model.

In this embodiment, as shown in fig. 6, the outer dial 31 is provided with four lock pin insertion holes 311 into which the unlocking pin 23 can be inserted, and the four lock pin insertion holes 311 are uniformly distributed on the circumference of 360 degrees, so that the direction of the handle bar is not required to be split when the handle bar is installed, thereby avoiding the error of installation and being capable of installing the handle bar more quickly. When the unlocking pin 23 is inserted into one of the pin insertion holes 311, the inner and outer turning peaches form a whole body which is rotated, so that the door can be opened more quickly outside the door.
