Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically to a right-angle lock with a press-to-reset mechanism. Background Technology

[0002] Most existing right-angle locks operate by inserting and turning a key, which in turn rotates the bolt to open or close the lock. This type of lock typically requires the key to be tightened or removed and then reset to ensure the bolt is fully engaged and locked. On one hand, if the key is lost or temporarily unavailable, it's difficult for the user to reset the lock, reducing its emergency adaptability. On the other hand, most existing locks lack intuitive locking status indicators, making it impossible to determine if the lock is fully closed without touching the bolt; confirmation relies on sound or touch, resulting in a poor user experience and potential security risks. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this application is to provide a right-angle lock with press-to-reset mechanism to solve the problems mentioned in the background art.

[0004] According to one aspect of this application, a right-angle lock with push-to-reset mechanism includes a lock housing, a push-button sleeve, a lock shaft, a spring, and a latch. The lock housing is fixedly installed on a door or window. A mounting hole is provided on the central axis of the lock housing. A push-button sleeve is slidably installed within the mounting hole, with its top extending beyond the upper opening of the mounting hole. A through hole is provided on the central axis of the push-button sleeve. The outer wall of the lock shaft is rotatably disposed within the through hole. A spring is positioned between the bottom of the push-button sleeve and the bottom of the mounting hole, and is sleeved on the outer periphery of the lock shaft. A recessed lock cylinder is provided on the top of the lock shaft. A connecting post is fixedly provided on the bottom of the lock shaft. The connecting post is rotatably disposed at the lower opening of the mounting hole, and its lower end extends beyond the lower opening of the mounting hole and is fixed to the latch. The lock shaft has two symmetrically shaped spiral grooves on its outer side wall, with a deflection angle of 90 degrees. Two pins are symmetrically inserted into the side wall of the pressing sleeve, with the ends of each pin extending into one of the spiral grooves. When the right-angle lock is locked, the ends of the pins are located at the lower end of the spiral grooves, and the top of the pressing sleeve is flush with the top of the lock housing. The spring is compressed. When the right-angle lock is unlocked, the ends of the pins are located at the upper end of the spiral grooves, and the top of the pressing sleeve extends upward beyond the top of the lock housing. During downward pressing of the pressing sleeve, the ends of the pins slide downward within the spiral grooves. The lock shaft rotates 90 degrees, causing the latch to rotate 90 degrees to lock.

[0005] Preferably, a semi-circular self-locking groove is provided on the upper side of the lower end of the two spiral waist-shaped grooves. The diameter of the semi-circular self-locking groove is consistent with the diameter of the pin. The pressing sleeve drives the pin to abut against the semi-circular self-locking groove under the elastic force of the spring.

[0006] Preferably, two grooves are formed along the circumference of the top edge of the lock shaft, the angular distance between the two grooves is 90 degrees, and the two grooves are respectively set to red and green. A visible notch is formed on the top of the pressing sleeve, located directly above one of the grooves. When the right-angle lock is in the locked state, the red groove is directly opposite the visible notch, and when the right-angle lock is in the unlocked state, the green groove is directly opposite the visible notch.

[0007] Preferably, the bottom of the lock case is provided with a fan-shaped groove with an angle of 90 degrees, and a limiting block is fixed on the lock tongue, the limiting block being located within the fan-shaped groove.

[0008] Preferably, sliding limit strips are fixedly provided on both sides of the inner sidewall of the assembly hole, and sliding limit grooves are provided on both sides of the outer sidewall of the pressing sleeve, with the two sliding limit grooves slidably connected to the two sliding limit strips respectively.

[0009] Preferably, the locking tongue is fixedly connected to the connecting post by screws.

[0010] Preferably, O-rings are embedded on the outer wall of the pressing sleeve and the outer wall of the locking shaft.

[0011] The advantages of this application compared to existing technologies are as follows: This application provides a right-angle lock with a press-to-reset mechanism. Through the design of the press sleeve, when the right-angle lock is in the unlocked state, the top of the press sleeve extends beyond the top of the lock housing. Pressing the press sleeve downwards overcomes the spring force, causing the pin end on it to slide downwards within the spiral groove. This rotates the lock shaft 90 degrees, causing the bolt to rotate 90 degrees to lock, enabling the bolt to lock quickly without a key. This simplifies the operation process and improves ease of use, making it particularly suitable for applications requiring temporary and rapid locking. Furthermore, the semi-circular self-locking groove on the upper side of the lower end of the spiral groove allows for... When the right-angle lock is in the locked state, the pin end is located at the lower end of the spiral waist-shaped groove, and the pressing sleeve, under the elastic force of the spring, drives the pin to abut against the semi-circular self-locking groove to complete the self-locking, improving the reliability and security of the lock. By setting red and green in the two grooves on the top of the lock shaft respectively, the red groove can be seen from the visible notch when the right-angle lock is in the locked state, and the green groove can be seen from the visible notch when the right-angle lock is in the unlocked state. This allows users to intuitively judge the open or closed state of the lock without frequently checking the position of the bolt, improving the intuitiveness and security of the operation and avoiding safety hazards caused by misjudgment.

[0021] To make the content of this application easier to understand, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the accompanying drawings. Figure 3 In the context of direction, the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figures 1 to 8As shown, a right-angle lock with push-to-reset mechanism includes a lock housing 1, a push-button sleeve 2, a lock shaft 3, a spring 4, and a latch 5. The lock housing 1 is fixedly installed on a door or window. A mounting hole 6 is provided on the central axis of the lock housing 1. The push-button sleeve 2 is slidably mounted within the mounting hole 6. Sliding limit strips 16 are fixedly provided on both sides of the inner wall of the mounting hole 6. Sliding limit grooves 17 are provided on both sides of the outer wall of the push-button sleeve 2. The two sliding limit grooves 17 are slidably connected to the two sliding limit strips 16 respectively. This design ensures that the push-button sleeve 2 only slides up and down within the mounting hole 6. Furthermore, the top of the push-button sleeve 2 can extend beyond the upper opening of the mounting hole 6. A through hole is provided on the central axis of the push-button sleeve 2. The outer wall of the lock shaft 3 is rotatably positioned within the through hole, located between the bottom of the push-button sleeve 2 and the bottom of the mounting hole 6. A spring 4 is provided, which is sleeved on the outer periphery of the lock shaft 3. When the right-angle lock is in the locked state, the spring 4 is in a compressed state. O-rings 19 are embedded on the outer wall of the pressing sleeve 2 and the outer wall of the lock shaft 3, which are sealed with the inner wall of the lock shell 1 to effectively prevent dust, moisture and impurities from entering the internal mechanism and extend the service life. A recessed lock cylinder 7 is provided at the top of the lock shaft 3, and a connecting post 8 is fixedly provided at the bottom of the lock shaft 3. The connecting post 8 is rotatably located at the lower opening of the assembly hole 6. The lower end of the connecting post 8 extends beyond the lower opening of the assembly hole 6 and is fixedly connected to the lock tongue 5 by a screw 18. A fan-shaped groove 14 is provided at the bottom of the lock shell 1. The angle of the fan-shaped groove 14 is 90 degrees. A limiting block 15 is fixedly provided on the lock tongue 5. The limiting block 15 is located in the fan-shaped groove 14. This allows for precise control of the locking and unlocking positions of the latch 5, ensuring consistent operation each time. Two symmetrical spiral grooves 9 are formed on the outer wall of the locking shaft 3, with a deflection angle of 90 degrees. Two pins 10 are symmetrically inserted into the side wall of the pressing sleeve 2, with their ends extending into the spiral grooves 9. Pressing or rotating the key causes the pins 10 to slide up and down along the grooves, driving the locking shaft 3 and the pressing sleeve 2 to move in tandem. The 90° deflection of the grooves precisely corresponds to the locking angle of the latch 5, ensuring that the locking position is reached each time. A semi-circular self-locking groove 11 is formed on the upper side of the lower end of the two spiral grooves 9. The diameter of the semi-circular self-locking groove 11 is consistent with the diameter of the pin 10. The pressing sleeve 2 is supported by the spring 4. Under the action of elastic force, the pin 10 is driven to abut against the semi-circular self-locking groove 11 to complete the self-locking; two grooves 12 are opened along the circumference of the top edge of the lock shaft 3, and the angle distance between the two grooves 12 is 90 degrees. The two grooves 12 are respectively set to red and green. A visible notch 13 is opened on the top of the pressing sleeve 2 directly above one of the grooves 12. When the right angle lock is in the locked state, the red groove 12 is directly opposite the visible notch 13. When the right angle lock is in the unlocked state, the green groove 12 is directly opposite the visible notch 13. Through the red and green visible grooves 12 set on the top of the lock shaft 3, the user can intuitively judge the open or closed state of the lock without frequently checking the position of the lock tongue 5, which improves the intuitiveness and safety of the operation and avoids the safety hazards caused by misjudgment.

[0023] In the above design, by setting the pressing sleeve 2, when the right-angle lock is in the unlocked state, the top of the pressing sleeve 2 extends beyond the top of the lock case 1. By pressing the pressing sleeve 2 downward, it can overcome the elastic force of the spring 4, and drive the end of the pin 10 on it to slide downward in the spiral waist-shaped groove 9, so that the lock shaft 3 rotates 90 degrees and drives the lock tongue 5 to rotate 90 degrees to lock, so that the lock tongue 5 can quickly lock without a key, simplifying the operation process and improving the convenience of use. It is especially suitable for application scenarios that require temporary quick locking. By opening a semi-circular self-locking groove 11 on the upper side of the lower end of the spiral waist-shaped groove 9, when the right-angle lock is in the locked state, the end of the pin 10 Located at the lower end of the spiral waist-shaped groove 9, and with the spring force of the spring 4, the pressing sleeve 2 drives the pin 10 on it to abut against the semi-circular self-locking groove 11 to complete self-locking, thus improving the reliability and security of the lock. By setting the two grooves 12 at the top of the lock shaft 3 to red and green respectively, the red groove 12 can be seen from the visible notch 13 when the right-angle lock is in the locked state, and the green groove 12 can be seen from the visible notch 13 when the right-angle lock is in the unlocked state. This allows the user to intuitively judge the open or closed state of the lock without frequently checking the position of the bolt 5, improving the intuitiveness and security of the operation and avoiding misjudgment that may lead to safety hazards.

[0024] Working principle: When the right-angle lock is in the locked state, the end of the pin 10 is located at the lower end of the spiral groove 9, and the top of the pressing sleeve 2 is flush with the top of the lock housing 1. The spring 4 is in a compressed state, and the red groove 12 can be seen from the visible notch 13. When the right-angle lock is in the unlocked state, the end of the pin 10 is located at the upper end of the spiral groove 9, and the top of the pressing sleeve 2 extends upward beyond the top of the lock housing 1. The green groove 12 can be seen from the visible notch 13. When it is necessary to lock again, it can be manually... Pressing down on the pressing sleeve 2 overcomes the elastic force of the spring 4, causing the end of the pin 10 on it to slide downward in the spiral waist-shaped groove 9, so that the locking shaft 3 rotates 90 degrees and drives the locking tongue 5 to rotate 90 degrees to lock, allowing the locking tongue 5 to lock quickly without a key, simplifying the operation process and improving the convenience of use, especially suitable for application scenarios that require temporary quick locking; and under the elastic force of the spring 4, the pressing sleeve 2 drives the pin 10 on it to abut against the semi-circular self-locking groove 11 to complete the self-locking.
