Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically, to a door lock assembly. Background Technology

[0002] Existing technology CN118895894A discloses a door lock structure, including a cover plate with a lock block that can be extended or retracted within it; a housing connected to the cover plate, with an opening on one side corresponding to the inner side of the door leaf; an abutment block that can be slidably disposed within the housing, and having an abutment portion that abuts or separates from the lock block. When the abutment portion is in contact with the lock block, the lock block retracts into the cover plate; when the abutment portion is separated from the lock block, the lock block extends out of the cover plate. The abutment block has a mating surface; and an operating block, a locking block, and an unlocking plate. This utility model has a reasonable structural design. By providing an opening on one side of the housing and by providing the unlocking plate, operating block, locking block, and abutment block, the lock can be locked by moving the operating block and unlocked by pressing the unlocking plate. This allows for locking and unlocking of the lock block, improving the overall aesthetics of the door leaf and achieving the effect of concealing the deadbolt.

[0003] The door lock structure described above only has an opening and unlocking plate on one side of the housing corresponding to the inside of the door leaf, which makes it inconvenient for users to open the door outward from the outside of the door leaf. Summary of the Invention

[0004] This utility model overcomes the shortcomings of the prior art and provides a door lock with a reasonable structural design. By setting an external opening and a rotating operating piece, it facilitates the operation of opening the door outward, improving the convenience and practicality of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A door lock assembly includes a lock housing, an inner opening on one side of the lock housing, a lock block that can extend or retract into the lock housing, an abutment block that can be reset and movably engaged with or disengaged from the lock block, an operating block that can be reset and movably engaged with or disengaged from the abutment block, a locking block that can be reset and rotatably engaged with or disengaged from the operating block, and an unlocking plate that is located at the inner opening and can be reset and rotatably engaged with or disengaged from the locking block. The operating block has an operating part corresponding to the unlocking plate. An outer opening is provided on the other side of the lock housing opposite to the inner opening, and an operating plate is rotatably provided at the outer opening of the lock housing.

[0006] By adopting the above technical solution, the lock block, abutment block, operating block, locking block, and unlocking plate are all located inside the lock housing. When the lock housing is installed in the door leaf, the inner opening corresponds to the inner side of the door leaf, and the outer opening corresponds to the outer side of the door leaf. The door leaf will also have openings corresponding to the inner and outer openings. When the unlocking plate and operating plate are not pressed, they will cover the openings to achieve a concealed appearance. Specifically, both the unlocking plate and operating plate can be equipped with pressing tabs to achieve a flush alignment with the openings in the door leaf, thus achieving better aesthetics and concealment. Compared with the prior art, the main improvement of this application lies in the setting of an outer opening and a rotating operating plate, thereby achieving the purpose of an outward-opening door. Specifically, the user presses the operating plate from the outside of the door, causing the operating plate to rotate inward. This creates a gap between the door opening and the operating plate, allowing the user to insert their fingers. By inserting their fingers into this gap, the user can pull the door, opening it either outward or inward. This makes opening the door outward more convenient (in the case of not being locked, the door can be pushed to open it inward). This solves the problem of existing technologies making it difficult to open the door outward from the outside.

[0007] Preferably, the operating block is provided with a limit block, which can abut against the operating piece to limit the rotation distance of the operating piece. When the operating block moves to abut against the abutment block and causes the abutment block to separate from the locking block, the locking block extends out of the lock housing to achieve reverse locking. At this time, the limit block moves with the operating block to limit the inward rotation distance of the operating piece. It also includes a hook piece, which can extend between the outer opening and the operating piece and act on the locking block to achieve unlocking.

[0008] By adopting the above technical solution, under normal use, the locking and unlocking operations are performed from the inside of the door leaf. The specific process is as follows: When locking, pressing the unlocking plate exposes a hole between the unlocking plate and the door leaf for a finger to insert. Inserting a finger and moving the operating part causes the operating block to move and abut against the abutment block, separating the abutment block from the lock block. The lock block extends to achieve locking, and at this time, the locking block locks the operating block. When unlocking, pressing the unlocking plate rotates it to abut against the locking block, disengaging the locking block from the operating block. The operating block then moves back to its original position, and the abutment block also moves back to its original position and abuts against the lock block again, causing the lock block to retract into the housing, thus unlocking. The moving or rotating reset function can be achieved using common elastic components such as springs, tension springs, or torsion springs. Due to the setting of the limit block, when the operating block moves to abut against the abutment block, the limit block restricts the inward rotation distance of the operating plate. When the door is locked, it cannot be unlocked directly by pressing the control lever from the outside, ensuring privacy inside the house. After pressing the control lever, it is limited by the stop block. At this time, the control lever will still rotate to a certain angle, and there will be a gap between the control lever and the door opening. Fingers cannot be inserted into this gap, and fingers cannot move the locking block to unlock it. However, due to the presence of a hook, which is thin, a hook can be inserted into the gap and act on the locking block, causing the locking block to disengage from the control lever, thus unlocking the door. This operation can be used in unexpected situations where the door must be unlocked from the outside.

[0009] Preferably, the limiting block is located on the side of the operating block away from the abutting block, and the operating part is also provided corresponding to the operating piece.

[0010] By adopting the above technical solution, this setting can also realize the deadbolt function on the outside of the door. When performing this operation, the user should quickly move the operating part to complete the deadbolt operation to prevent the limit block from pressing outward against the operating piece as the operating block moves closer to the abutment block, thereby pinching the operator's fingers.

[0011] Preferably, the limiting block has a groove on one side corresponding to the unlocking piece.

[0012] By adopting the above technical solution, the groove is designed so that when the locking operation is performed, the limiting block moves with the operating block. At this time, the groove will move to the position of the corresponding unlocking piece. When the unlocking piece is pressed to unlock, the unlocking piece can be located in the groove. The limiting block will not affect the unlocking piece from contacting the locking block to perform the unlocking operation, so that the unlocking piece can unlock normally.

[0013] Preferably, when the abutment block and the locking block separate, the locking block extends out of the lock housing under the elastic restoring force or its own weight.

[0014] By adopting the above technical solution, when the abutting block does not abut against the locking block, the locking block extends out of the lock housing and remains in a locked state. The locking block can be equipped with a counterweight to check the lock housing by its own weight, or a torsion spring can be equipped on the locking block to extend out of the lock housing by elastic restoring force.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-7As shown, a door lock assembly includes a lock housing 1, an inner opening 2 on one side of the lock housing 1, a lock block 3 that can extend or retract into the lock housing 1, an abutment block 4 that can be reset and moved and abutted or separated from the lock block 3, an operating block 5 that can be reset and moved and abutted or separated from the abutment block 4, a locking block 6 that can be reset and rotated and locked or separated from the operating block 5, and an unlocking piece 21 that is disposed at the inner opening 2 and can be reset and rotated to abutted or separated from the locking block 6. The operating block 5 is provided with an operating part 53 corresponding to the unlocking piece 21. An outer opening 7 is provided on the other side of the lock housing 1 opposite to the inner opening 2, and an operating piece 71 is reset and rotated at the outer opening 7 of the lock housing 1.

[0019] By adopting the above technical solution, the lock block 3, abutment block 4, operating block 5, locking block 6, and unlocking plate 21 are all located inside the lock housing 1. When the lock housing 1 is installed in the door leaf, the inner opening 2 corresponds to the inner side of the door leaf, and the outer opening 7 corresponds to the outer side of the door leaf. The door leaf will also have openings corresponding to the inner opening 2 and the outer opening 7. When the unlocking plate 21 and the operating plate 71 are not pressed, they will cover the openings to achieve concealment. Specifically, both the unlocking plate 21 and the operating plate 71 can be equipped with pressing tabs to achieve a flush alignment with the openings in the door leaf, thus achieving better aesthetics and concealment. Compared with the prior art, the main improvement of this application lies in the setting of the outer opening 7 and the rotating operating plate 71, thereby achieving the purpose of an outward-opening door. Specifically, the user presses the operating piece 71 from the outside of the door leaf, causing the operating piece 71 to rotate inward. This creates a gap between the door leaf opening and the operating piece 71, allowing the user to insert their fingers. By inserting their fingers into this gap, the user can pull the door leaf, opening it either outward or inward. This makes opening the door leaf outward more convenient (in the case of not being locked, the door leaf can be pushed to open it inward). This solves the problem of existing technologies making it difficult to open the door leaf outward from the outside.

[0020] Furthermore, the operating block 5 is provided with a limit block 51, which can abut against the operating piece 71 to limit the rotation distance of the operating piece 71. When the operating block 5 moves to abut against the abutting block 4 and causes the abutting block 4 to separate from the locking block 3, the locking block 3 extends out of the lock housing 1 to achieve reverse locking. At this time, the limit block 51 moves with the operating block 5 to limit the inward rotation distance of the operating piece 71. It also includes a hook piece 8, which can extend between the outer opening 7 and the operating piece 71 and act on the locking block 6 to achieve unlocking.

[0021] By adopting the above technical solution, under normal use, the locking and unlocking operations are performed from the inside of the door leaf. The specific process is as follows: When locking, pressing the unlocking piece 21 exposes a hole between the unlocking piece 21 and the door leaf for a finger to insert. Inserting a finger and moving the operating part 53 causes the operating block 5 to move and abut against the abutment block 4, separating the abutment block 4 from the locking block 3. The locking block 3 then extends to achieve locking. At this time, the locking block 6 locks the operating block 5. When unlocking, pressing the unlocking piece 21 rotates it to abut against the locking block 6, disengaging the locking block 6 from the locking of the operating block 5. The operating block 5 then moves back to its original position, and the abutment block 4 also moves back to its original position and abuts against the locking block 3 again, causing the locking block 3 to retract into the housing, thus unlocking. The moving or rotating reset function can be achieved using common elastic components such as springs, tension springs, or torsion springs. Due to the setting of the limiting block 51, when the operating block 5 moves to abut against the abutment block 4, the limiting block 51 will restrict the inward rotation distance of the operating piece 71. That is, when locked, it cannot be unlocked directly by pressing the operating piece 71 from the outside of the door, ensuring the privacy of the inside of the house. After pressing the operating piece 71, the operating piece 71 is limited by the limiting block 51. At this time, the operating piece 71 will still rotate to a certain angle, and there will be a gap between the operating piece 71 and the door opening. Fingers cannot be inserted into this gap, and fingers cannot move the locking block 6 to unlock. However, due to the setting of the hook piece 8, which is a thin sheet, by inserting the hook piece 8 into the above-mentioned gap and acting on the locking block 6, the locking block 6 is released from locking the operating block 5, and the unlocking function can also be achieved. This operation can be used in unexpected situations where it is necessary to unlock and open the door from the outside of the door.

[0022] Furthermore, the limiting block 51 is located on the side of the operating block 5 away from the abutment block 4, and the operating part 53 is also provided corresponding to the operating piece 71. With this arrangement, the door can also be locked from the outside. When performing this operation, the user must quickly move the operating part to complete the locking operation, to prevent the limiting block 51 from pressing outward against the operating piece 71 as the operating block 5 moves closer to the abutment block 4, thereby preventing injury to the operator's fingers.

[0023] Furthermore, the limiting block 51 has a groove 52 on one side corresponding to the unlocking piece 21. When performing a reverse locking operation, the limiting block 51 moves with the operating block 5. At this time, the groove 52 moves to the position corresponding to the unlocking piece 21. When the unlocking piece 21 is pressed to unlock, it can be located in the groove 52. The limiting block 51 will not affect the unlocking piece 21's contact with the locking block 6 for unlocking, allowing the unlocking piece 21 to unlock normally.

[0024] Furthermore, when the abutting block 4 separates from the locking block 3, the locking block 3 extends out of the lock housing 1 under the elastic restoring force or its own weight. With this configuration, when the abutting block 4 is not abutting the locking block 3, the locking block 3 extends out of the lock housing 1 to maintain the anti-locked state. The locking block 3 can be equipped with a counterweight that presses against the lock housing 1 under its own weight, or it can be equipped with a torsion spring that extends out of the lock housing 1 under the elastic restoring force. For the specific transmission details of the locking block 3 in achieving anti-locking and unlocking, please refer to CN118895894A.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
