Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically to a rotary-opening impact lock. Background Technology

[0002] A strike lock is a common type of door lock used to control the automatic locking of doors. Its basic principle is that when the door closes, the bolt or locking block strikes the locking pin on the door frame, automatically locking under the action of a spring or sliding mechanism, thus achieving a quick locking effect without manual operation. This type of structure has certain advantages in improving ease of use, and is especially suitable for occasions requiring rapid locking.

[0003] However, existing impact locks have the following technical problems: First, traditional structures rely on large spaces for layout, making them difficult to adapt to thinner doors and limiting their application range; second, most impact locks only have a single manual unlocking method, such as rotating a key or handle, lacking multi-mode control methods; third, some structures lack mechanical linkage coordination during locking or unlocking, which may lead to problems such as jamming or incomplete positioning between the bolt and the locking pin, affecting the reliability and service life of the lock.

[0004] In addition, some lock body structures that currently have key or knob unlocking do not take into account the convenience of operation in keyless mode, thus limiting their use scenarios. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a rotary-opening impact lock to solve the problems mentioned in the background art.

[0006] According to one aspect of this application, a rotary-opening impact lock includes a lock housing, an unlocking rod, a latch, an electric push rod, and a rotary switch. The lock housing has a square shell structure, with the unlocking rod and latch rotatably mounted inside. The unlocking rod is locked to the latch, and the latch is lockable to a door frame lock post. A locking slot is provided on the lock housing at the connection position between the latch and the lock post. The electric push rod is fixedly installed inside the lock housing. The electric contact portion of the unlocking rod is opposite to the protruding end of the electric push rod. The manual contact portion of the unlocking rod extends out of the side wall of the lock housing and connects to the rotary switch. The rotary switch is fixedly installed on the outer side wall of the lock housing.

[0007] Preferably, the unlocking lever includes a rotating block, a contact rod, a second contact rod, and a locking angle. The center of the rotating block is rotatably disposed inside the lock housing. A contact rod is fixedly disposed on one side of the rotating block. A strip-shaped hole is opened on the side wall of the lock housing at the position of the contact rod. The contact rod passes through the strip-shaped hole and is connected to the rotary switch. A second contact rod is fixedly disposed on the other side of the rotating block. The second contact rod is disposed opposite to the extended end of the electric push rod. A locking angle is fixedly disposed on the side of the second contact rod near the bolt. The locking angle abuts against and locks against the bolt. A torsion spring is disposed at the center of the rotating block to allow it to return to its initial state.

[0008] Preferably, the latch includes a second rotating block, a locking rod, and a locking block. The center of the second rotating block is rotatably disposed within the lock housing. A locking rod is fixedly disposed on the side of the second rotating block near the unlocking rod. The end of the locking rod abuts against the locking angle for locking connection. A locking block is fixedly disposed on the other side of the second rotating block. The locking block is correspondingly disposed with the locking slot. A U-shaped opening slot is provided on the locking block. The U-shaped opening slot engages with the locking pin.

[0009] Preferably, the locking angle near the side of the rotating block is a smooth arc structure, and the end of the locking rod is a rounded corner structure, and the rounded corner end of the locking rod can slide along the smooth arc side of the rotating block.

[0010] Preferably, the rotary switch includes a support, an L-shaped push rod, a spring, a lock sleeve, a lock cylinder, a knob, an eccentric cam, and a torsion spring. The support is fixedly installed on the outer wall of the lock housing. A lock sleeve is fixedly mounted on the support. A lock cylinder is rotatably mounted inside the lock sleeve. The core of the lock cylinder is located at one opening of the lock sleeve. The shaft of the lock cylinder extends to the other opening of the lock sleeve and is fixedly connected to the knob by screws. An eccentric cam is fixedly mounted on the shaft of the lock cylinder located inside the lock sleeve. A torsion spring is sleeved on the shaft of the lock cylinder. One end of the torsion spring is fixedly mounted on the eccentric cam, and the other end is fixedly mounted on the eccentric cam. A sliding sleeve is fixedly mounted on the lock sleeve along the horizontal direction of the outer wall of the lock housing. The sliding part of the L-shaped push rod is slidably disposed in the sliding sleeve. A square slot is opened through the sliding part. A baffle is fixedly mounted on the support. The baffle is disposed in the square slot. The spring is disposed in the square slot, with one end fixedly abutting against the baffle and the other end fixedly abutting against the side wall of one end of the square slot. One side of the pushing part of the L-shaped push rod is in contact with the eccentric cam, and the other side of the pushing part is in contact with the contact rod.

[0011] Preferably, the axis of the second contact rod is set at a 90-degree angle to the axis of the first contact rod, and the axis of the locking rod is set at a 90-degree angle to the axis of the locking block.

[0012] Preferably, the rotating block one, the contact rod one, the contact rod two, and the locking angle are integrally formed, and the rotating block two, the locking rod, and the locking block are integrally formed.

[0013] Preferably, when the knob or the lock cylinder core is rotated, the lock cylinder shaft rotates, causing the eccentric cam to rotate, which in turn pushes the pushing part of the L-shaped push rod to move. This causes the pushing part to push the first contact rod to rotate around the center of the first rotating block, causing the second contact rod to rotate away from the locking rod, thus separating the locking rod from the locking angle. This allows the locking block to rotate around the center of the second rotating block and thus separate from the lock pin to unlock.

[0014] When the locking pin strikes the U-shaped opening groove of the locking block, the locking block rotates in the opposite direction around the center of the second rotating block, causing the rounded end of the locking rod to contact the smooth arc side of the first rotating block and slide along its surface, causing the locking rod to press the locking angle to rotate around the center of the first rotating block away from the locking rod, causing the rounded end of the locking rod to rotate to the upper side of the locking angle so that the two abut against each other and lock together;

[0015] When the extended end of the electric push rod extends, it pushes the second contact rod to rotate around the center of the first rotating block, thereby causing the locking angle to rotate away from the locking rod, so that the locking rod separates from the locking angle, and the locking block can rotate around the center of the second rotating block and thus separate from the locking pin to unlock.

[0016] The advantages of this application compared with the prior art are as follows: The rotary-opening impact lock of this application, through the linkage structure of the electric push rod and the knob, can be manually unlocked by the knob (keyless) or the key driving the rotary switch, or electrically unlocked by the electric push rod controlling the unlocking rod, meeting the needs of multiple operation scenarios; the impact lock has a compact overall structure, the lock shell adopts a square shell, and the internal components are arranged by rotation and sliding, which can be easily embedded in thin door panels, thus broadening the installation and adaptation range of the impact lock.

The locking angle 24 abuts against the lock tongue 3. The locking connection is achieved by a torsion spring 53 at the center of the rotating block 21, which allows it to return to its initial state. The rotating block 21, the contact rod 22, the contact rod 23, and the locking angle 24 are integrally formed. The center of the rotating block 21 is rotatably located inside the lock housing 1. A locking rod 32 is fixedly provided on the side of the rotating block 21 near the unlocking rod 2. The end of the locking rod 32 abuts against the locking angle 24 for a locking connection. A locking block 33 is fixedly provided on the other side of the rotating block 21. The axis of the locking rod 32 is aligned with the axis of the locking block 33.

In addition, the side of the locking angle 24 near the rotating block 21 is a smooth arc structure, and the end of the locking rod 32 is a rounded corner structure. The rounded end of the locking rod 32 can slide along the smooth arc side of the rotating block 21.

[0026] In one embodiment, combined Figure 2The rotary switch 5 includes a support 51, an L-shaped push rod 52, a spring 53, a lock sleeve 54, a lock cylinder, a knob 56, an eccentric cam 57, and a torsion spring 58. The support 51 is fixedly installed on the outer wall of the lock housing 1. The lock sleeve 54 is fixedly mounted on the support 51. The lock cylinder is rotatably mounted inside the lock sleeve 54. The core part 551 of the lock cylinder is located at one end of the lock sleeve 54. The shaft part 552 of the lock cylinder extends to the other end of the lock sleeve 54 and is fixedly connected to the knob 56 by screws. An eccentric cam 57 is fixedly mounted on the shaft part 552 of the lock cylinder located inside the lock sleeve 54. A torsion spring 58 is sleeved on the shaft part 552 of the lock cylinder. One end of the torsion spring 58 is fixedly mounted on the eccentric cam 57 and the other end is fixedly mounted on the eccentric cam 57. A sliding sleeve 511 is fixedly mounted on the lock sleeve 54 and horizontally along the outer wall of the lock housing 1 on the support 51. The sliding part 521 of the L-shaped push rod 52 is slidably disposed in the sliding sleeve 511. A square slot 522 is opened through the sliding part 521. A baffle 512 is fixedly mounted on the support 51. The baffle 512 is disposed in the square slot 522. A spring 53 is disposed in the square slot 522, with one end fixedly abutting against the baffle 512 and the other end fixedly abutting against the side wall of one end of the square slot 522. One side of the pushing part 523 of the L-shaped push rod 52 is in contact with the eccentric cam 57 and the other side of the pushing part 523 is in contact with the contact rod 22.

[0027] Working principle: When the knob 56 or the lock cylinder core 551 is rotated, the lock cylinder shaft 552 rotates, driving the eccentric cam 57 to rotate, which in turn pushes the pushing part 523 of the L-shaped push rod 52 to move. This causes the pushing part 523 to push the contact rod 22 to rotate around the center of the rotating block 21, causing the contact rod 23 to drive the locking angle 24 away from the locking rod 32, thus separating the locking rod 32 from the locking angle 24. This causes the locking block 33 to rotate around the center of the rotating block 31, thereby separating from the lock pin 6 and unlocking (e.g., Figure 3 and Figure 4 (As shown); the unlocking lever 2 is restored to its initial state by the action of the torsion spring (as shown). Figure 5 (As shown).

[0028] When the locking pin 6 strikes the U-shaped opening groove 34 of the locking block 33, the locking block 33 rotates in the opposite direction around the center of the rotating block 21, causing the rounded end of the locking rod 32 to contact the smooth arc side of the rotating block 21 and slide along its surface, causing the locking rod 32 to press the locking angle 24 to rotate around the center of the rotating block 21 away from the locking rod 32 (e.g. Figure 6 (As shown), causing the rounded end of the locking lever 32 to rotate to the upper side of the locking angle 24 so that the two abut against each other and lock together;

[0029] When the extended end of the electric push rod 4 extends, it pushes the contact rod 23 to rotate around the center of the rotating block 21, thereby causing the locking angle 24 to rotate away from the locking rod 32, so that the locking rod 32 separates from the locking angle 24, and the locking block 33 can rotate around the center of the rotating block 31 and then separate from the locking pin 6 to unlock.

[0030] The above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, without departing from the spirit and scope defined by the claims of this application.
