Description

Technical Field

[0001] The utility model relates to a lock, in particular to a door lock body. Background Art

[0002] Locks are important components for security and property protection. Wooden doors are currently the most commonly used door material, which has the characteristics of being elegant and beautiful. However, they are prone to deformation after long-term use. After the door is deformed, it is easy for the lock bolt to be unable to align with the keyhole, affecting the locking effect.

[0003] For example, there is currently a lock body with a sky and earth lock, which has a horizontal lock bolt and a sky and earth rod. Generally speaking, the position between the horizontal lock bolt and the corresponding lock slot is relatively difficult to change, and is less affected by deformation. The position of the sky and earth rod is more affected, which is difficult to align after deformation, resulting in the problem that the entire lock body cannot be locked. Therefore, a lock body with a sky and earth rod is needed that can allow the lock bolt to lock normally even if the sky and earth rod is bent or offset from the corresponding position of the lock slot when in use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a door lock body that can allow the lock bolt to be locked normally even when the top and bottom rods are bent or offset to the corresponding position of the lock slot.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A door lock body, comprising

[0007] The lock bolt performs locking and unlocking actions by telescoping;

[0008] The top and bottom rod performs locking and unlocking actions by extending and retracting;

[0009] Actuator, used to drive the lock bolt to extend and retract and the top and bottom rods to retract;

[0010] A driving mechanism, used for driving the actuator to move;

[0011] The sky and earth rods maintain a tendency to move outwards through the elastic force of the elastic component;

[0012] The actuator is connected to a lock buckle, which abuts against the top and bottom rods through elastic force to limit the extension of the top and bottom rods. The actuator is also linked with the lock buckle. When the actuator drives the lock bolt to extend, the actuator drives the lock buckle to release the restriction on the top and bottom rods; the top and bottom rods are extended by elastic force.

[0013] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0014] As a further improvement of the present invention, the top and bottom rods include a first rod, a second rod and a linkage member; the linkage member is connected to the first rod through a gear, and is also fixedly connected to the second rod in the extension direction of the second rod; the driving mechanism is linked to the linkage member, and the linkage member is driven to move through the driving mechanism to synchronously drive the first rod and the second rod to retract.

[0015] As a further improvement of the present invention, the driving mechanism includes an electric driving mechanism and a manual driving mechanism, and both the electric driving mechanism and the manual driving mechanism are linked with the actuator to drive the actuator to move.

[0016] As a further improvement of the utility model, it also includes a sensor, which is electrically connected to the electric drive mechanism to feed back a start signal to the electric drive mechanism. After receiving the start signal, the electric drive mechanism drives the actuator to act.

[0017] As a further improvement of the present utility model, the manual drive mechanism includes a manual rotating shaft, a driving handle circumferentially fixed on the manual rotating shaft, a linkage handle rotatably connected to the manual rotating shaft, and a driving rod arranged on the driving handle for driving the linkage handle to rotate. When the manual rotating shaft rotates, the driving handle is driven to rotate, and the linkage handle is driven to rotate through the driving rod, and the actuator is driven to operate. The driving handle also retracts the first rod and the second rod by driving the linkage member.

[0018] As a further improvement of the present invention, the actuator includes a gear set and a lever, the gear set is connected to the electric drive mechanism, and the electric drive mechanism drives the gear set to rotate, thereby driving the lever to rotate. After the lever rotates, the lock bolt is extended and retracted; the gear set is also connected to the linkage handle, and when the linkage handle rotates, it drives the gear set to rotate, thereby retracting the lock bolt.

[0019] The beneficial effect of the utility model is that the top and bottom rods themselves are popped out only by elastic force, and do not require the participation of a driving mechanism and an actuator. Therefore, even if the top and bottom rods are bent or the door frame is deformed so that the top and bottom rods cannot be locked normally, it will not affect the normal driving of the driving mechanism and the actuator to extend the lock bolt (i.e. lock).

[0027] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0028] Reference Figure 1-6 As shown,

[0029] A door lock body, comprising

[0030] The lock bolt 1 performs locking and unlocking actions by telescoping;

[0031] The top and bottom rod 2 performs locking and unlocking actions by extending and retracting;

[0032] The actuator 3 is used to drive the lock bolt 1 to extend and retract the top and bottom rods 2;

[0033] A driving mechanism 4, used for driving the actuator 3 to move;

[0034] The sky and earth pole 2 maintains a tendency to move outwards through the elastic force of the elastic component;

[0035] The actuator 3 is connected to a lock buckle 5, which abuts against the top and bottom rod 2 through elastic force to limit the extension of the top and bottom rod 2. The actuator 3 is also linked with the lock buckle 5. When the actuator 3 drives the lock bolt 1 to extend, the actuator 3 drives the lock buckle 5 to release the restriction on the top and bottom rod 2; the top and bottom rod 2 is extended by elastic force.

[0036] In this solution, the top and bottom rods 2 are pushed out by elastic force, and when the top and bottom rods 2 are retracted, they are restricted by the lock buckle 5 so that they will not pop out automatically. Only when the driving mechanism 4 performs the driving action, will it drive the actuator 3 to unlock the lock buckle 5. At this time, the top and bottom rods 2 are extended under the action of elastic force and enter the bolt hole corresponding to the door frame for locking. Since the top and bottom rods 2 are only ejected by elastic force, the driving mechanism 4 and the actuator 3 are not required to participate. Therefore, even if the top and bottom rods 2 are bent or the door frame is deformed, causing the top and bottom rods 2 to be unable to be locked normally, it will not affect the driving mechanism 4 and the actuator 3 to drive the bolt 1 to be extended (i.e. locked). When the driving mechanism 4 and the actuator 3 cooperate to drive the bolt 1 to be retracted (i.e. unlocked), the top and bottom rods 2 can be brought back by the driving mechanism 4 or the actuator 3 to restore it to unlocking. At this time, the lock buckle 5 will abut against the top and bottom rods 2 through elastic force, which can lock the top and bottom rods 2 so that it will not be extended under the action of elastic force.

[0037] The cooperation between the lock 5 and the top and bottom rod 2 can refer to Figure 1 , 3 As shown in FIGS. 4 and 6 , a groove is provided on the top and bottom rod 2 , which enables the lock buckle 5 to be embedded in and clamp the top and bottom rod 2 so that it will not extend out under the action of elastic force.

[0038] In the above-mentioned setting, the sky and earth rod 2 can only have one sky rod or one ground rod, and of course, it can also have both. For example, the sky and earth rod 2 includes a first rod 21, a second rod 22 and a linkage member 23; the linkage member 23 is connected to the first rod 21 through a gear 24, and is also fixedly connected to the second rod 22 in the extension direction of the second rod 22; the driving mechanism 4 is linked with the linkage member 23, and the linkage member 23 is driven to move by the driving mechanism 4 to synchronously drive the first rod 21 and the second rod 22 to retract.

[0039] In this solution, a rack meshing with the gear 24 is provided at the position of the linkage member 23 corresponding to the gear 24. Similarly, the first rod 21 connected to the gear 24 also has a rack. At this time, when the linkage member 23 moves with the driving mechanism 4, it can pull the first rod 21 by rotating the driving gear 24, so that the first rod 21 can be retracted. The linkage member can also be directly connected to the second rod 22 to directly pull the second rod 22 back when moving. Based on this solution, the driving mechanism 4 and the linkage member 23 only need to cooperate when retracting the first rod 21 and the second rod 22. When the first rod 21 and the second rod 22 extend outward under the action of elastic force, they will not be affected by the linkage rod. Figure 1 As shown in FIG, a gap can be reserved between the linkage member 23 and the driving mechanism 4, so that the linkage member 23 can move when the first rod 21 and the second rod 22 are ejected outward under the elastic force. The elastic force source of the first rod 21 and the second rod 22 can be a torsion spring or a spring.

[0040] In order to make the driving more intelligent, the driving mechanism 4 includes an electric driving mechanism 41 and a manual driving mechanism 42 . Both the electric driving mechanism 41 and the manual driving mechanism 42 are linked with the actuator 3 to drive the actuator 3 to move.

[0041] The manual drive mechanism 42 can provide a basic manual drive method, such as driving by rotating a physical key to cooperate with the actuator 3 to act. Of course, the physical key can be used as an unlocking step, and then it can be rotated by turning the handle to cooperate with the actuator 3 to act.

[0042] The electric drive mechanism 41 can be driven by a motor. For example, the electric password lock is first unlocked, and then the electric drive mechanism 41 is controlled to drive after the unlocking is successful.

[0043] In the preferred solution, a sensor 6 is further included. The sensor 6 is electrically connected to the electric drive mechanism 41 to feed back a start signal to the electric drive mechanism 41. After receiving the start signal, the electric drive mechanism 41 drives the actuator 3 to operate.

[0044] The sensor 6 can be used to sense whether the door is closed. After sensing that the door is closed, the electric drive mechanism 41 starts to drive the actuator 3 to operate. The relationship between the sensor 6 and the electric drive mechanism 41 can be that the electric drive mechanism 41 includes a control chip, and the sensor 6 cooperates with the control chip to control the operation of the electric drive mechanism 41 through the control chip. Alternatively, a control chip (such as an electronic password lock) is also connected between the sensor 6 and the electric drive mechanism 41, and the electric drive mechanism 41 is also controlled by the control chip to operate.

[0045] In this solution, the sensor 6 can be a Hall sensor that can detect magnetic components. A magnet can be set at the position corresponding to the Hall sensor on the door frame. After the door is closed, the Hall sensor can sense the magnet and trigger the locking action.

[0046] As an optional embodiment in the manual drive structure, the manual drive mechanism 42 includes a manual rotating shaft 421, a driving handle 422 circumferentially fixed on the manual rotating shaft 421, a linkage handle 423 rotatably connected to the manual rotating shaft 421, and a driving rod 424 arranged on the driving handle 422 for driving the linkage handle 423 to rotate. When the manual rotating shaft 421 rotates, it drives the driving handle 422 to rotate, and drives the linkage handle 423 to rotate through the driving rod 424, and drives the actuator 3 to operate. The driving handle 422 also retracts the first rod 21 and the second rod 22 by driving the linkage member 23.

[0047] The manual rotating shaft 421 is a rotating shaft connected to the handle, and can drive the manual rotating shaft 421 to rotate when the handle rotates. Figure 1 As shown in , a hollow square hole is reserved. When the handle drives the manual shaft 421 to rotate to unlock, the driving handle 422 is rotated with it. At this time, the driving handle 422 can move with the linkage 23, thereby retracting the first rod 21 and the second rod 22.

[0048] It should be noted that the lock body is divided into a lock tongue 7, a lock bolt 1, and a top and bottom rod 2. The lock tongue 7 is used as a basic quick locking component, and the lock bolt 1 and the top and bottom rod 2 are used as safety locks. When it is necessary to completely unlock, the lock tongue 7, the lock bolt 1, and the top and bottom rod 2 all need to be retracted. The driving handle 422 also cooperates with the manual rotating shaft 421 to retract the lock tongue 7. The electric driving mechanism 41 is used to drive the lock bolt 1 and the top and bottom rod 2 to retract and unlock or extend and lock, that is, to release the safety lock or start the safety lock. The lock tongue 7 is retracted by manual drive.

[0049] Among them, the linkage handle 423 is a component that cooperates with the manual shaft 421. When the handle is turned to unlock, the manual shaft 421 rotates and the linkage handle 423 is rotated through the driving rod 424. The linkage handle 423 drives the actuator 3 to move and retract the lock bolt 1.

[0050] Reference Figure 2 As shown in the figure, the actuator 3 includes a gear set 31 and a lever 32. The gear set 31 is connected to the electric drive mechanism 41, and can be driven by the electric drive mechanism 41 to rotate the gear set 31, thereby driving the lever 32 to rotate. The lever 32 rotates and then drives the lock bolt 1 to extend and retract. The gear set 31 is also connected to the linkage handle 423. When the linkage handle 423 rotates, it can also drive the gear set 31 to rotate, thereby retracting the lock bolt 1. When the lock tongue 7 is retracted, the drive rod 424 is in a state of abutting the linkage handle 423, and both are in the unlocking position. At this time, when the electric drive mechanism 41 drives to lock, it can drive the linkage handle 423 to rotate in the opposite direction through the gear set 31. The linkage handle 423 will push the drive rod 424 to make the drive handle 422 rotate in the opposite direction, thereby locking the lock tongue 7, the lock bolt 1, and the top and bottom rods 2. Of course, the lock tongue 7 and the manual rotating shaft 421 can also pop out automatically under the action of elastic force. At this time, the driving handle 422 and the driving rod 424 are reset. However, since the linkage handle 423 itself is rotationally connected to the manual rotating shaft 421, the linkage handle 423 will remain in the position corresponding to the unlocked state. When the electric drive mechanism 41 is driven, the linkage handle 423 will rotate together and return to the position corresponding to the locked state.

[0051] That is, in this solution, the electric drive mechanism 41 can lock the lock tongue 7, the lock bolt 1, and the top and bottom rod 2 at one time, and the manual drive mechanism 42 can unlock the lock tongue 7, the lock bolt 1, and the top and bottom rod 2 when rotating. The manual drive mechanism 42 can be divided into an inside-door drive and an outside-door drive. The inside-door drive can be set to unlock the lock tongue 7, the lock bolt 1, and the top and bottom rod 2 at one time (to achieve rapid escape), and the outside-door drive can be set to retract the lock bolt 1 and the top and bottom rod 2 through electronic unlocking, and then retract the lock tongue 7 by turning the handle (with higher safety). This differential drive method is a mature structure in the prior art, so it will not be described in detail.

[0052] In further optimization, the driving handle 422 includes a first handle 4221 and a second handle 4222, the first handle 4221 is used to cooperate with the first handle for fixed connection, the second handle 4222 is used to cooperate with the first handle for fixed connection, the manual rotating shaft 421 includes a first rotating shaft 4211 and a second rotating shaft 4212, the first rotating shaft 4211 and the second rotating shaft 4212 are connected to be relatively rotatable, the driving rod 424 is installed on one of the first handle 4221 or the second handle 4222 and is linked to the driving rod 424, and has a gap with the other one.

[0053] The first rotating shaft 4211 and the second rotating shaft 4212 can rotate relative to each other. Specifically, they can be connected by coaxial plugging, so that the first rotating shaft 4211 and the second rotating shaft 4212 can maintain a relative rotation state. The driving rod 424 can be coaxially sleeved on the first rotating shaft 4211 or the second rotating shaft 4212 to maintain a certain degree of rotation freedom. The first handle and the second handle can be used as indoor handles and outdoor handles.

[0054] In the above structure, the driving rod 424 is installed on the first handle 4221. At this time, only when the first handle is rotated can the driving rod 424 be rotated, thereby driving the linkage handle 423 to simultaneously retract the lock tongue 7, the lock bolt 1, and the top and bottom rod 2, while the rotation of the second handle will be in an idle state and cannot be unlocked. This solution can correspond to the first handle being an indoor handle and the second handle being an outdoor handle, and the first handle can be used to achieve rapid escape.

[0055] On the contrary, if the linkage handle 423 is installed on the second handle 4222, the installation direction of the lock body can be changed to achieve the left and right locking interchangeability. At this time, the second handle serves as an indoor handle and the first handle serves as an outdoor handle, and quick escape can be achieved through the second handle.

[0056] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
