Description
Technical Field
[0001] This invention belongs to the field of escape door lock technology, specifically relating to an escape lock for rapid escape. Background Technology
[0002] Escape locks, also known as fire escape locks, are escape devices used on the doors of passageways in public places such as large supermarkets, shopping malls, office buildings, hospitals, schools, factories, and residential buildings. The function of escape locks is to prevent unauthorized personnel from entering the premises, while providing a safe passage for people inside when they need to escape.
[0003] Door locks typically consist of a locking mechanism and a transmission mechanism. A key transmits power through the transmission mechanism to the locking mechanism, thus unlocking or locking. However, the transmission mechanism of existing door locks is composed of numerous interconnected parts. During normal use, external impacts are inevitable, causing the precision of the components in the transmission mechanism to deviate or decrease due to these impacts. If a door lock with a similarly complex transmission mechanism is applied to an escape door, the reduced precision of the transmission mechanism may require a longer time to open in emergencies such as fires. In a crisis, even an extra second of unlocking time could threaten the lives of those escaping.
[0004] In emergency situations, such as fires, people experience fear and panic. In such environments, they are less patient to slowly turn the key to unlock the door. Therefore, overly complex structures are not suitable for emergency situations. There is an urgent need for an escape door lock structure that is simple to operate and can be unlocked quickly.

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.
[0030] like Figures 1-5As shown, an escape lock for quick escape includes a lock housing 1, a lock cylinder assembly 2, a lock handle assembly 3, an abutment assembly 4, a transmission lever 5, and a linkage disc 6; the lock cylinder assembly 2 and the lock handle assembly 3 are both installed on the lock housing 1, and the lock cylinder assembly 2 and the lock handle assembly 3 are located on the same side of the lock housing 1. The lock handle assembly 3 is unlocked by the lock cylinder assembly 2, and then the door is opened by the lock handle assembly 3.
[0031] The lock handle assembly 3 includes a connecting square rod 31, a linkage disc 6, a transmission lever 5, and an abutment assembly 4, which are sequentially arranged on the connecting square rod 31. The linkage disc 6 is located on the side closest to the lock handle assembly 3 and is engaged with the lock handle assembly 3. The transmission lever 5 is used to engage the linkage disc 6 from one side. The abutment assembly 4 is used to engage the linkage disc 6 from the opposite direction of the engagement of the transmission lever 5. The other end of the transmission lever 5 is in limiting contact with the lock cylinder assembly 2, and the abutment of the linkage disc 6 is released by the lock cylinder assembly 2. Since the linkage disc 6 is engaged with the lock handle assembly 3, the lock handle assembly 3 rotates. When the linkage disc 6 is rotated, it can be driven to rotate. Conversely, when the linkage disc 6 is abutted, the lock handle assembly 3 cannot rotate. Because the transmission lever 5 and the abutting component 4 abut against the linkage disc 6 from two opposite directions, the linkage disc 6 is restricted in all directions, thereby locking the lock handle assembly 3. At the same time, the transmission lever 5 and the lock cylinder assembly 2 are in a limiting abutment, so that the transmission lever 5 is driven to slide under the action of the lock cylinder assembly 2, thereby contacting the linkage disc 6. At this time, only the abutting component 4 sleeved on the connecting square rod 31 abuts the linkage disc from one direction. When the locking cylinder assembly 2 engages with the linkage disc 6, the lock handle assembly 3 is unrestricted and can rotate freely. This simple structure provides a convenient and quick unlocking environment for escapees in emergencies, preventing panic and further anxiety caused by complex unlocking procedures. Conversely, the simple design of this system allows the lock cylinder assembly 2 to drive the transmission lever 5 to unlock the linkage disc 6. After the engagement is released, the lock handle assembly 3 can be rotated directly. These two steps complete the unlocking process, making the process faster. In emergencies, users do not need to perform complex operations; they can simply unlock the lock handle assembly 3 using the lock cylinder assembly 2, providing valuable time for escape. Due to the tight cooperation between the components and the impact-resistant design of the linkage disc 6, this escape lock effectively resists external impacts, preventing locking or jamming caused by external factors. This not only simplifies operation but also improves safety. Due to its compact and modular design, this escape lock can be widely used in various places, such as schools, office buildings, shopping malls, and other densely populated areas.
[0032] To ensure the actuation effect of the transmission paddle 5 on the linkage disc 6, in one embodiment, the linkage disc 6 has a first arc-shaped locking portion 61 on its surface, and the transmission paddle 5 has a U-shaped first concave plate 51. The opposite surfaces of the first concave plate 51 are provided with ramp portions 511. The first concave plate 51 slides on the surface of the linkage disc 6, and the ramp portions 511 on both sides engage with the first arc-shaped locking portion 61. That is, the first arc-shaped locking portion 61 engages between the ramp portions 511 on both sides. The symmetrical engagement on both sides can achieve a stable connection and increase the stability of the door lock. With the horizontal plane as the reference, the vertical plane abuts, which can achieve a stable engagement with the first arc-shaped locking portion 61. This avoids the transmission paddle 5 from shaking during the sliding process when only the ramp portion 511 is in contact with the first arc-shaped locking portion 61, thus causing unstable and unsmooth unlocking.
[0033] In one embodiment, the abutment component 4 includes a slide plate 41. The slide plate 41 is provided with a transverse groove 411. Abutment blocks 42 protruding from the body of the slide plate 41 are vertically symmetrically arranged at both ends of the transverse groove 411. The side of the abutment block 42 facing away from the transverse groove 411 is located on the linkage disc 6. The vertical end face of the abutment block 42 abuts against the first arc-shaped locking part 61 in the opposite direction to the ramp 511. When the abutment block 42 and the ramp 511 are in the locked state, the ramp 511 abuts against the lower end of the first arc-shaped locking part 61, and the abutment block 42 abuts against the upper end of the first arc-shaped locking part 61, thereby restricting the movement of the linkage disc 6 and thus locking the lock handle component 3. When installed on the same axis, the symmetrical abutment blocks 42 are located inside the first concave plate 51, making the abutment force of the transmission lever 5 and the slide plate 41 against the linkage disc 6 more concentrated.
[0034] The transmission lever 5 and the sliding plate 41 abut against the linkage disc 6 from both sides. If there is no safety lock to prevent the transmission lever 5 and the sliding plate 41 from being locked, the abutment can still be released when the door lock assembly is rotated. Therefore, to ensure the abutment effect of the transmission lever 5 and the sliding plate 41, in one embodiment, the abutment assembly 4 further includes a circular safety element 43. The circular safety element 43 is fixedly sleeved on the connecting square rod 31. The circular safety element 43 is provided with an arc block 431. The bottom surface of the arc block 431 abuts against the top surface of the abutment block 42, and the side surface of the arc block 431 abuts against the transverse groove 411. The length of the abutment block 42 is less than the transverse groove 411. The vertical groove spacing of the groove 411 and the horizontal groove 411 form a locking space for the arc block 431 with the abutment block 42. The height of the abutment block 42 is exactly the same as the height of the first arc locking part 61. When the abutment block 42 is located on the linkage disc 6, the rigidity of the abutment block 42 is just flush with the first arc locking part 61. The circular safety piece 43 is sleeved on the connecting square rod 31. The arc block 431 extends to the locking space, thereby abutting the abutment block 42 against the first arc locking part 61. The transmission lever 5 is also abutted by the lock core assembly 2, thereby completely locking the linkage disc 6 from the upper and lower ends of the first arc locking part 61.
[0035] In one embodiment, the side of the linkage disc 6 opposite to the first arc-shaped locking part 61 is provided with a second arc-shaped locking part 62, and the number of second arc-shaped locking parts 62 is two; the lock handle assembly 3 includes a fixing block 32, a door handle 33, and a circular locking block 34; the fixing block 32 penetrates through the lock housing 1, the door handle 33, and the connecting square rod 31, the door handle 33 and the connecting square rod 31 are respectively located on both sides of the lock housing 1, the circular locking block 34 is coaxially connected to the fixing block 32 and is on the same side as the connecting square rod 31, the circular locking block 34 is axially provided with two evenly distributed locking grooves, the second arc-shaped locking part 62 is locked into the locking groove, and the linkage disc 6 is used for The linkage disc 6 is engaged with the fixing block 32 via the second arc portion to restrict the rotation of the door handle 33. This ensures that the linkage disc 6, the fixing block 32, and the door handle 33 are in the same state. That is, when the door handle 33 rotates, the linkage disc 6 rotates with the door handle 33. When the linkage disc 6 is restricted, the door handle 33 is resisted and cannot rotate. When the door handle 33 is subjected to external force and attempts to rotate, the restriction effect of the linkage disc 6 can prevent the door handle 33 from rotating. Only when the lock cylinder releases the abutment of the toggle block on the linkage disc 6 will the linkage disc 6 not restrict the rotation of the door handle 33 when the door handle 33 is rotated.
[0036] In one embodiment, the lock handle assembly 3 further includes a first spring 44 and a second spring 45. The first spring 44 is sleeved on the inner ring of the circular locking block 34 and abuts against the linkage disc 6. The second spring 45 is sleeved on the outer ring of the circular locking block 34, and the end of the second spring 45 extends out of the circular locking block 34 to engage with the lock housing 1. The function of the second spring 45 is that after the door handle 33 is turned, the door handle 33 will automatically turn to the initial state under the action of the second spring 45, so that the door handle 33 can automatically return to its original state. When used in home and other environments, it can improve the convenience of the door lock system, so that opening and closing the door can be done by simply turning the handle, simplifying the unlocking and locking process. At the same time, the elasticity of the second spring 45 can reduce the risk of the locking loosening or falling off due to external force, and improve the impact resistance of the system.
[0037] In one embodiment, the lock cylinder assembly 2 includes a key 21, a lock body 22, a lock cylinder component 23, and a cam block 24. The lock cylinder component 23 is installed inside the lock body 22 and has a lock slot for inserting the key 21. The lock slot communicates with the cam block 24. A cam block groove is provided at the end of the lock body 22 away from the lock slot. The cam block 24 is rotatably mounted in the cam block groove. The design of the cam block 24 is such that when it rotates, it can interact with the transmission lever 5, thereby driving the transmission lever 5 to move and releasing the abutment of the transmission lever 5 against the linkage disc 6. That is, the lock cylinder assembly 2 can unlock the handle assembly through the transmission lever 5, thereby driving the unlocking or locking mechanism of the entire lock. At the same time, when the door lock is in the locked state, the cam block 24 is in a stationary state, and the transmission lever 5 abuts against the linkage disc 6, so that the transmission lever 5 abuts against the linkage disc 6. This means that when the door handle 33 is turned without the action of the lock cylinder assembly 2, the linkage assembly is locked by the abutment of the transmission lever 5 and the lock cylinder assembly 2, and the handle cannot be turned.
[0038] In one embodiment, the transmission lever 5 is provided with a second concave plate 52 in the shape of a concave shape. The first concave plate 51 and the second concave plate 52 form an H-shaped structure. The cam block 24 can rotate within the second concave plate 52 to achieve abutment transmission with the transmission lever 5. Secondly, the transmission structure of existing door locks has a large number of transmission parts and a complex connection structure. In daily use, door locks are inevitably subjected to impacts, which leads to a decrease in the connection accuracy of the parts. The decrease in connection accuracy results in a longer time to unlock the door, and the probability of failure is higher for a larger number of parts. The transmission lever 5 can play a role in transmission and locking in the door lock structure. The second concave plate The second concave plate 52 abuts against the cam block 24 to achieve the transmission effect. The second concave plate 52 drives the first concave plate 51 to move. The first concave plate 51 abuts against the linkage disc 6 to achieve the locking effect. The transmission paddle 5 replaces the traditional connection of many parts to achieve the transmission effect, which is suitable for use in escape door locks. A trigger block 53 is installed on one side wall of the second concave plate 52. The trigger block 53 is provided with two baffles 531. A trigger groove 532 is formed between the two baffles 531. When the cam block 24 rotates, it abuts against the trigger groove 532. The baffles 531 are arc-shaped on the side closer to each other and flat on the side further away, so that the trigger block 53 has three parts that abut against the cam block 24, i.e., triggering. The planar structure of the groove 532 and the two baffles 531 allows the cam block 24 to contact the trigger block 53 in the shortest possible time when the key 21 drives the cam block 24 to rotate. During rotation, the cam block 24 abuts against the baffle 531, causing the trigger block 53 to move away from the linkage disc 6. By setting the trigger block 53 on the second concave plate 52, the up-and-down movement of the transmission lever 5 is achieved through the engagement between the trigger block 53 and the cam block 24. Compared to spring reset, existing escape door locks, in order to achieve a fast response and a fast reset effect for the bolt, also use elastic components such as springs as part of the transmission structure. In this embodiment, an elastic structure is used in the escape door lock to enhance its functionality. However, due to the elasticity of the components, the elasticity may decrease after prolonged use, leading to issues such as inability to lock or incomplete transmission. In this embodiment, a non-elastic trigger block 53 structure is used to transmit the transmission between the second concave plate 52 and the cam block 24. This ensures that the door lock will not be affected by the unlocking and locking times even after prolonged use. Compared to elastic structures, this method offers higher reliability. By setting three abutment structures, the probability of contact between the cam block 24 and the trigger block 53 is increased, allowing the transmission lever 5 to complete the limiting abutment transmission effect on the linkage disc 6 in a shorter time.
[0039] In one embodiment, the lock housing 1 is further equipped with a first limiting block 71, a second limiting block 72, and a third limiting block 73 arranged sequentially; the linkage disc 6 is located between the first limiting block 71 and the second limiting block 72, and the center of the linkage disc 6 is on the same straight line as the centers of the first limiting block 71, the second limiting block 72, and the third limiting block 73. The design of each limiting block ensures accurate engagement and stable contact between the transmission lever 5 and the slider and the linkage disc 6, reducing the possibility of loosening or jamming due to vibration or impact, and ensuring that the lever and the slider are in contact. During contact, the range of motion is within the distance of the limiting blocks. The slide plate 41 is provided with a vertical groove, the vertical groove spacing of which is greater than the straight-line distance between the first limiting block 71 and the second limiting block 72. The slide plate 41 slides between the first limiting block 71 and the second limiting block 72. The design of the vertical groove allows the slide plate 41 to slide between the first limiting block 71 and the second limiting block 72. When the linkage disc 6 rotates, the arc part continuously abuts against the abutment block 42 during the rotation process, thereby allowing the two ends of the vertical groove to slide between the first limiting block 71 and the second limiting block 72. This achieves locking and unlocking of the linkage disc 6 by contacting it; the bottom of both the first concave plate 51 and the second concave plate 52 are provided with limit grooves, and the limit grooves are respectively in limiting contact with the second limit block 72 and the third limit block 73. When the limit groove at the first concave plate 51 abuts with the second limit block 72, the transmission lever 5 is in the contact state with the linkage disc 6. When it slides down under the action of the lock cylinder assembly 2, the limit groove at the second concave plate 52 abuts with the third limit block 73. At this time, the transmission lever 5 is in the state of releasing the contact with the linkage disc 6. At the same time, the transmission... The lever 5 slides between the second limiting block 72 and the third limiting block 73, limiting the sliding distance between the linkage plates. This makes unlocking the lock cylinder assembly 2 simple. When the key 21 drives the cam block 24 to rotate and acts on the transmission lever 5, the transmission lever 5 can only slide between the second limiting block 72 and the third limiting block 73. This enables the lever block and the linkage disc 6 to unlock quickly in real time. It is not necessary for the lever block to fully contact the cam block 24 after rotating many times. This enables the door handle to unlock quickly and increases the escape time.
[0040] In one embodiment, a sealing cover is also included, which is detachably connected to the lock housing 1. The lock housing 1 has an arched structure, and the lock cylinder assembly 2, lock handle assembly 3, abutment assembly 4, transmission lever 5, and linkage disc 6 are all located in the arched space. This space is large enough to accommodate all the internal components and ensure that they can work properly under various operating conditions. At the same time, the arched structure also provides additional strength and stability to resist external impacts and vibrations and protect the internal components from damage.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
