Description

Technical Field

[0001] The present invention relates to the technical field of locks, and more particularly to a novel door lock body structure. Background Art

[0002] In the prior art, the inclined lock tongue of the door lock is generally set as a plane on one side of the door opening direction and an inclined surface on the other side of the door closing direction, so that when closing the door, the door body can be directly pushed, and the lock tongue is retracted into the lock body along the inclined surface. After closing, it is popped out by a spring, and the plane on the side of the door opening direction is used to lock the door. When opening the door, this type of door lock needs to rotate the handle on the outer door or the inner door and other structures to actively retract the lock tongue into the lock body to open the door.

[0003] At present, with the gradual popularization of electronic smart door locks, the existing oblique lock tongue structure requires turning the handle to open the door, and the entire lock tongue is pulled into the lock shell by the handle to unlock it. After it is applied to the electronic door lock, the handle and other structures arranged on the door are driven by a motor. Since the motor directly drives the lock tongue to retract and retract, its load is large, the required motor is also large, the volume is also large, and the cost is high. At the same time, the motor is prone to damage when it often drives a large load, and the service life is not high. Therefore, a new lock body structure is urgently needed, so that after it is applied to the electronic door lock, the load on the motor is small and the service life is long. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a new door lock body structure, which has the advantages of directly pushing and pulling the door body when opening and closing the door, without turning the handle, and is more convenient to use. Moreover, when used in an electronic door lock, the load on the motor is small, which effectively extends the service life of the door lock.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel door lock body structure, comprising an oblique lock tongue and a lock shell, characterized in that: the oblique lock tongue comprises a main lock tongue and an auxiliary lock tongue swinging relative to the main lock tongue, a lock tongue plate is arranged on the oblique lock tongue, and the oblique lock tongue is hinged at the front end of the lock tongue plate; a locking plate is arranged in the lock shell, the locking plate abuts against the rear end of the lock tongue plate to constrain the lock tongue plate to move into the lock shell, and the locking plate is elastically arranged in the lock shell and can move up and down, a first unlocking device and a second unlocking device are arranged in the lock shell, the first unlocking device comprises an unlocking plate slidably connected in the lock shell, the unlocking plate elastically abuts against the auxiliary lock tongue, when the door is closed, the swing of the auxiliary lock tongue will drive the unlocking plate to press down the locking plate to release the constraint of the locking plate on the lock tongue plate; the second unlocking device comprises a rotor, when the door is opened, the rotation of the rotor will drive the locking plate to press down to release the constraint of the locking plate on the lock tongue plate.

[0006] The present invention is further configured as follows: the rotor is arranged above the locking plate, a small rotor that can rotate independently relative to the rotor is arranged inside the rotor, the rotor and the small rotor are provided with grooves on the rotation path, and a protrusion is arranged on the locking plate, and the protrusion is also located on the rotation path of the rotor and the small rotor. When the protrusion is stuck in the groove, the locking plate is lifted up to restrict the movement of the locking tongue plate. When the rotor or the small rotor rotates and the cooperation between the groove and the protrusion is released, the locking plate will be pressed down by the rotor or the small rotor to release the constraint of the locking plate on the locking tongue plate.

[0007] The present invention is further configured as follows: a slope surface is provided at one end of the unlocking plate close to the locking plate, and the unlocking plate presses down the locking plate via the slope surface during the movement.

[0008] The present invention is further configured as follows: the unlocking plate is a "U"-shaped structure, one closed end of which abuts against the auxiliary lock tongue, and a return spring is arranged in the unlocking plate. The return spring extends from the open end of the "U"-shaped structure and abuts between the unlocking plate and the lock housing.

[0009] The present invention is further configured as follows: a small spring is provided below the locking plate to drive it to lift up, the lock housing is provided with a spring groove below the locking plate, and the small spring abuts between the locking plate and the spring groove to lift the locking plate.

[0010] The present invention is further configured as follows: a small square core is arranged inside the small rotor and rotates synchronously therewith, the small square core is connected to an external driving device, and the rotor is connected to another external driving device.

[0011] The present invention is further configured as follows: an oblique groove is provided on the main lock tongue, the auxiliary lock tongue is arranged in the oblique groove, a limit block is also extended from the main lock tongue, and a limit groove for the limit block to move is correspondingly provided in the lock shell; a pin is also provided on the oblique lock tongue, and the main lock tongue, the auxiliary lock tongue and the lock tongue plate are hinged by the pin.

[0012] The present invention is further configured as follows: a flange is provided on the auxiliary lock tongue, and when the auxiliary lock tongue rotates around the pin, the flange pushes the unlocking plate to move into the lock housing.

[0013] The present invention is further configured as follows: the lock housing comprises a lower housing bottom and a housing cover, and the lower housing bottom and the housing cover are detachably connected.

[0014] In summary, the present invention has the following beneficial effects:

[0015] Compared with the prior art, the present invention changes the structure of the inclined lock tongue and divides the inclined lock tongue into a main lock tongue and an auxiliary lock tongue. The main lock tongue and the auxiliary lock tongue can rotate relative to each other. In the unlocked state, that is, when the locking plate is pressed down by the second unlocking device, the push of the hand when opening the door will drive the main lock tongue to rotate, so that the main lock tongue and the auxiliary lock tongue form an inclined plane. When closing the door, the auxiliary lock tongue is driven to rotate, so that the auxiliary lock tongue and the main lock tongue form an inclined plane. Then, as the door body moves, the entire lock tongue will move along the inclined plane to the inside of the lock body, thereby realizing convenient opening and closing of the door; in the locked state, since the locking plate is tilted, the lock tongue plate is The locking plate is restricted and cannot retract inward. After the main lock tongue rotates, it cannot drive the lock tongue plate to move, so the door cannot be opened. When closing the door, the auxiliary lock tongue will first drive the unlocking plate to move, so that the slope on the unlocking plate presses down on the locking plate, so that the lock tongue plate can be locked back inward. After the door is closed, the unlocking plate and the lock tongue plate will pop out under the action of the reset spring. Through this lock body structure, in the unlocked state, the door can be opened and closed directly by pushing and pulling the door body, unlike the prior art which relies on the rotation of the handle; in the locked state, the door body cannot be opened but can be closed.

[0016] The telescopic movement of the lock tongue of the present invention relies on the force of a person's hand when pushing or pulling the door to retract and retract. When the structure of the present invention is used on an electronic door lock, it is only necessary to use a small motor to drive the rotor or a small rotor to rotate, and control whether the locking plate is tilted or not to control the door lock without controlling the entire lock tongue. The motor only needs to drive a simple rotor or a small rotor, which greatly reduces the load. It can be driven by a small motor, which occupies a small volume and does not require a complex transmission mechanism, saving costs. The small load can effectively extend the service life of the motor, thereby improving the overall service life of the lock, solving the problem that the motor directly drives the lock tongue to retract and retract, the load is large, the motor required is also large, the volume is also large, the cost is high, and the motor is easily damaged when it often drives a large load, and the service life is not high.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] This embodiment discloses a new door lock body structure, such as Figure 1-8 As shown, it includes an oblique lock tongue 1 and a lock shell 2, the lock shell 2 includes a lower shell bottom 201 and a shell cover 202, and the two are detachably connected by screws. The oblique lock tongue 1 includes a main lock tongue 101 and an auxiliary lock tongue 102. The main lock tongue 101 is also provided with an oblique groove 4, and the auxiliary lock tongue 102 is arranged in the oblique groove 4. A limit block 5 is also extended from the main lock tongue 101, and a limit groove 6 for the limit block 5 to move is correspondingly arranged in the lock shell 2. During the flipping process of the main lock tongue 101, the limit block 5 will move in the limit groove 6 to achieve the effect of controlling the flipping angle of the main lock tongue 101. A lock tongue plate 7 is arranged on the oblique lock tongue 1, and a pin 8 is also arranged on the oblique lock tongue 1. The main lock tongue 101, the auxiliary lock tongue 102 and the lock tongue plate 7 are hinged by the pin 8, and an unlocking Plate 9, the unlocking plate 9 is a "U"-shaped structure, and its closed end is against the auxiliary lock tongue 102. A return spring 10 is also arranged inside the unlocking plate 9. The return spring 10 extends from the open end of the "U"-shaped structure and abuts between the unlocking plate 9 and the lock shell 2. The return spring 10 can also make the inclined lock tongue 1 pop out when not subject to external force. The lock tongue plate 7 and the unlocking plate 9 can both be telescopically slid in the lock shell 2, and there is also relatively independent sliding between the lock tongue plate 7 and the unlocking plate 9; a locking plate 1101 and a rotor 1102 and a small spring 1103 for controlling the tilting of the locking plate 1101 are also arranged in the lock shell 2. When locked, one end of the locking plate 1101 is tilted, and the tilted end is in contact with the lock tongue plate 7 to achieve the limitation of the lock tongue plate 7.

[0028] For further information, please refer to Figure 1-3 and Figure 6-8, whether the tilting of the locking plate 1101 controls whether the oblique lock tongue 1 can be retracted into the lock housing 2, when the locking plate 1101 tilts, such as Figure 6 As shown, when the oblique lock tongue 1 is retracted, the lock tongue plate 7 will be retracted, and the locking plate 1101 will block the lock tongue plate 7, thereby realizing the locking function; when you want to unlock, please refer to Figure 7 , Figure 7 The method is to push the unlocking plate 9 inward by the auxiliary lock tongue 102 so that the slope surface 12 on it first contacts the locking plate 1101, and then when the inclined lock tongue 1 is retracted, the lock tongue plate 7 and the unlocking plate 9 act together, and the locking plate 1101 is pressed down under the action of the slope surface 12, so that the lock tongue plate 7 can be smoothly retracted into the lock housing 2 to achieve unlocking; please refer to Figure 8 , the locking plate 1101 can also be pressed down by the rotation of the rotor 1102 and the small rotor 13. In the locked state, the grooves of the small rotor 13 and the rotor 1102 cooperate with the protrusion 15 on the locking plate, and the locking plate 1101 is tilted under the action of the small spring 1103. When the external driving device connected to the rotor 1102 or the small rotor 13 drives it to rotate, the groove 17 will rotate with it, so that the protrusion 15 is pressed down by the rotor 1102 or the small rotor 13. After being pressed down, the lock tongue plate 7 can be normally retracted into the lock shell 2, thereby achieving the unlocking effect; for further information, please refer to Figure 3 The rotor 1102 and the small rotor 13 rotate relatively independently, and both can press down the protrusion 15. The small rotor 13 is connected to an external driving device through the small square core 14, and the rotor 1102 is directly connected to another external driving device. Through the setting of the rotor 1102 and the small rotor 13, the action of the locking plate 1101 can be independently controlled by using the rotor 1102 and the small rotor 13.

[0029] For further information, please refer to Figure 4-5 ,exist Figure 4 In the embodiment, the auxiliary lock tongue 102 is turned over and inserted into the inclined groove 4, and the auxiliary lock tongue 102 and the main lock tongue 101 jointly form an inclined surface on one side of the auxiliary lock tongue 102. The action of the auxiliary lock tongue 102 causes the flange 16 on it to abut against the unlocking plate 9, pushing the unlocking plate 9 inward, for example Figure 7 As shown, the slope surface 12 can contact the locking plate 1101 first, and the action of the auxiliary lock tongue 102 is set in the door closing direction, so that the door closing action can be achieved by directly pushing the door regardless of whether the locking plate 1101 is pressed down; Figure 5In the process, the main lock tongue 101 is turned over and the auxiliary lock tongue 102 is stuck in the inclined groove 4, forming an inclined surface on one side of the main lock tongue 101. The action of the main lock tongue 101 is generally set in the direction of door opening. When the lock is released, the locking plate 1101 is pressed down by the rotor 1102 or the small rotor 13. When the door is opened and the door body is pushed, the main lock tongue 101 will be folded to form an inclined surface. Then, when the door body is continued to be pushed, the inclined lock tongue 1 will be pushed into the lock shell 2 due to the existence of the inclined surface, thereby realizing door opening. Through the coordinated action of the above-mentioned main lock tongue 101 and the auxiliary lock tongue 102, whether opening or closing the door, it can be achieved by pushing or pulling the door body, which is more convenient to use.

[0030] When the present invention is applied to an electronic lock, it only needs to set a driving motor on the rotor and set another driving motor on the small square core, so that the door lock can be locked and unlocked both inside and outside the door, so that the load of the motor is greatly reduced, and a motor with smaller volume and weight can be selected, which effectively reduces the volume and weight of the electronic door lock. In addition, due to the small load, the service life of the motor can also be effectively extended.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
