Figures 1a and 1b show the internal structure of the lock body structure in this embodiment from two viewing angles when it is locked and not locked. Figure 1a shows the structure on the inside side of the door, and Figure 1b shows the structure on the outside of the door. The structure of one side; Figure 2a shows the internal structure of the lock body structure in this embodiment when it is in the counter-locked state, and its viewing angle is the side inside the door; Figure 2b shows the lock body structure in this embodiment when it is in the counter-locked state. And the internal structure after unlocking is also viewed from the inside side of the door; Figure 3 shows the structure of the locking block in this embodiment; Figure 4 shows the first peach and the middle peach in this embodiment And the structure of peach.

Please refer to Figures 1a to 4. The lock body structure in this embodiment includes a lock tongue assembly disposed in the housing 1, a first dial 31, a second dial 32, a locking block 4 and a first spring 51. . The housing 1 can be made of two half-shells fastened together, with a cavity for accommodating the above-mentioned components formed in the middle. In order to show the internal structure of the lock body, only one half-shell of the housing 1 is shown in Figures 1a and 1b. A lock tongue hole for the lock tongue 22 to telescope is provided on one end surface of the housing 1 .

The lock tongue assembly is slidably disposed in the housing 1 and can slide along the telescopic direction of the lock tongue 22 . Specifically, the inner wall of the housing 1 is provided with a first chute 11, and the lock tongue assembly is provided with a first slide block 21 embedded in the first chute 11. The lock tongue 22 or the first dial 31 and the third Driven by the two peaches 32, the lock tongue assembly can slide in the first chute 11. In this embodiment, the lock tongue assembly includes a lock tongue 22, a driving frame 23 and a second spring 52. The first slider 21 is provided on the driving frame 23. The locking tongue 22 is provided at one end of the driving frame 23 . As the driving frame 23 slides in the housing 1 , the locking tongue 22 can extend outside the housing 1 or retract into the housing 1 . In addition, the lock tongue 22 is rotationally connected to the driving frame 23, and the direction of the inclined surface of the lock tongue 22 can be rotated during installation to adapt to left-hand or right-hand opening doors. One end of the second spring 52 is fixed, and the other end is connected to the driving frame 23, and exerts a force on the driving frame 23 toward the side of the lock tongue 22. Therefore, when the driving frame 23 moves to the right in Figure 1a to unlock, It will return to the left side under the force exerted by the second spring 52, that is, the lock tongue 22 will return to the outside of the housing 1 again.

In this embodiment, the first dial 31 and the second dial 32 are both rotatably arranged in the housing 1. They are respectively connected to the handles during use and can rotate in the housing 1. Please refer to Figure 4. A first boss 61 is provided on the outer periphery of the first dial 31. When the first dial 31 rotates, the side surface of the first boss 61 can abut against the unlocking platform 24, thereby driving the drive. The frame 23 slides inside the housing 1 . As shown in Figures 1a and 2b, after the side of the first boss 61 abuts the unlocking platform 24, as the first dial 31 continues to rotate clockwise, the drive frame 23 can be driven to slide to the right in the figure. , so that the lock tongue 22 enters the housing 1 to unlock.

In this embodiment, the second peach 32 is composed of a middle peach 33 and an outer peach 34, which are set on the same handle when in use and can rotate synchronously in the housing 1. The first peach 31 and the outer peach 34 are on both sides of the middle peach 33. The shape of the outer peach 34 is the same as that of the first peach 31, and a second boss 62 is provided on its outer periphery. When the second boss 62 rotates with the outer peach 34, the side thereof can also abut against the drive frame 23. The unlock card is on stage 24. In other words, unlocking platforms 24 are provided on both sides of the driving frame 23. During use, the first dial 31 or the outer dial 34 can drive the driving frame 23 to slide to the right in Figure 1a, thereby unlocking.

In addition, a third boss 63 is provided on the outer periphery of the middle dial peach 33. When the middle dial peach 33 rotates, the side surface of the third boss 63 can abut against the limiting column 13 in the housing 1. The limiting column 13 is fixed on the side wall of the housing 1 to assist in limiting the position of the centering peach 33. Since the outer peach 34 and the middle peach 33 move synchronously during use, when the rotation of the middle peach 33 is limited, The rotation of the external dial peach 34 is also limited. For example, in Figure 1a, Figure 2a and Figure 2b, the counterclockwise rotation of the middle peach 33 and the outer peach 34 is restricted; in Figure 1b, the clockwise rotation of the middle peach 33 and the outer peach 34 is restricted.

In this embodiment, the driving frame 23 has a U-shaped structure, and the lock tongue 22 is located at the bottom of the U-shaped structure. The length of one side of the driving frame 23 where the unlocking platform 24 is provided is greater than the length of the other side. The side is used to cooperate with the locking block 4 to release the anti-locking. Please refer to Figure 3. The locking block 4 is also rotatably installed in the housing 1, and its outer periphery is provided with a fourth boss 64, a fifth boss 65 and a sixth boss 66. During the rotation of the locking block 4 , the side surface of the fourth boss 64 can contact the end surface of the shorter side of the driving frame 23 , and the side surface of the fifth boss 65 can contact the first boss 61 and the end surface of the shorter side of the drive frame 23 . The side surfaces of the second boss 62 and the sixth boss 66 can be in contact with the side surfaces of the third boss 63 .

In other words, when the first dial 31 in Figure 1a rotates counterclockwise, after the side surface of the first boss 61 abuts the fifth boss 65, as the first dial 31 continues to rotate counterclockwise, the locking mechanism can be driven The block 4 rotates clockwise, thereby causing the side surface of the fourth boss 64 to contact the end surface of the shorter side of the drive frame 23, and at the same time, the side surface of the sixth boss 66 contacts the side surface of the third boss 63. That is, the state shown in Figure 2a. At this time, the lock body is in a reverse-locked state, and the rotation of the handle inserted on the middle dial 33 and the outer dial 34 is limited. In addition, when the driving frame 23 slides into the housing 1, its end surface can push the fourth boss 64 to rotate counterclockwise, thereby moving the sixth boss 66 away from the third boss 63, and releasing the rotation of the third boss 63. Restriction, at this time, the handles installed on the middle dial peach 33 and the outer dial peach 34 can be rotated, and the anti-locked state of the lock body is released.

The lock body structure is applied to a door lock. When in use, when the door is closed and not locked, its internal structure is as shown in Figure 1a and Figure 1b. At this time, if you need to unlock the door, you can turn the inner handle to drive the third door lock. A set of peaches 31 rotates clockwise or the outside handle drives the middle set peaches 33 and the outer set peaches 34 to rotate clockwise, thereby causing the drive frame 23 to slide into the housing 1, causing the lock tongue 22 to shrink into the housing 1, thereby realizing Unlock; when the door is closed and needs to be locked, the inner handle can be rotated to drive the first dial 31 to rotate counterclockwise, thereby causing the locking block 4 to rotate clockwise, so that the sixth boss 66 abuts the third boss 63. Thereby limiting the rotation of the outer handle, and finally realizing the reverse lock, that is, the state shown in Figure 2a; when it is necessary to release the reverse lock, the inner handle can be rotated to drive the first dial 31 to rotate clockwise, thereby causing the drive frame 23 to move toward the housing 1 It slides inward, causing the lock tongue 22 to retract into the housing 1. While unlocking, the driving frame 23 can also push the fourth boss 64 to the initial position, making the sixth boss 66 away from the third boss 63, and releasing the lock. The rotation restriction of the middle dial peach 33 and the outer dial peach 34 also releases the anti-lock. The descriptions of clockwise and counterclockwise here are based on the perspective from the inside side of the door, that is, from the perspective in Figure 1a, Figure 2a and Figure 2b.

The lock body structure can realize the locking, unlocking and reverse locking functions of traditional locks with fewer parts. It is applied to doors. If the handle is mistakenly operated to reverse lock when the door is not closed, the lock tongue 22 will retract during the closing process. In the housing 1, the locking block 4 can also be rotated to release the anti-lock. In addition, the second peach 32 adopts a split structure, namely the middle peach 33 and the outer peach 34. The outer peach 34 has the same structure as the first peach 31, and the sixth peach on the locking block 4 is Fifth bosses 65 are provided on both sides of the boss 66. During specific use, the outer handles can also be inserted into the first and

middle peaches

31 and 33, and the inner handles can be inserted into the outer peaches. 34, the lock body can be reversed to adapt to left-opening/right-opening doors without adjusting the internal structure. It should be noted that when there is no need to consider whether it is suitable for left-opening/right-opening doors, the middle turning peach 33 and the outer turning peach 34 can also be set as an integrated structure, that is, the second boss 62 and the third boss 63 are both It is arranged on the second dial peach 32 and can also realize the above-mentioned functions of locking, unlocking and reverse locking.

In this embodiment, a second slider 41 is also provided on one side of the fourth boss 64, and a second slider 12 for accommodating the second slider 41 is provided on the housing 1. The second slider 12 is an arc, used to limit the rotation angle of the locking block 4. Specifically, in Figure 1a, when the locking block 4 rotates counterclockwise, it stops after the second slider 41 contacts the right end of the second slide groove 12; The slider 41 stops after contacting the left end of the second slide groove 12 . In addition, a first spring 51 is also provided in the housing 1. As shown in Figures 1a and 1b, one end of the first spring 51 is hinged to the spring shaft 14 in the housing 1, and the other end is hinged to the second slider. 41, and the first spring 51 exerts force on the locking block 4, which can make the second slider 41 contact the end of the second slide groove 12, so that the locking block 4 can be locked or unlocked when the lock body is locked. It is in a more stable state to prevent the lock body from accidentally locking/unlocking. The spring shaft 14 is disposed at a central position on one side of the second slide groove 12. The first spring 51 is a torsion spring and has a tendency to expand outward. As shown in Figure 1a, when the second slider 41 is at the right end of the second slide groove 12, the first spring 51 exerts an urging force on the second slider 41 toward the upper right, so that the locking block 4 can be stably maintained at the right end. Unlocked state; as shown in Figure 2a, when the second slider 41 is at the left end of the second slide groove 12, the force exerted by the first spring 51 on the second slider 41 is toward the upper left, causing the locking block to 4. It can stably maintain the state when locked. In other embodiments, the second slide groove 12 can also be changed into two stops to limit the positions of the left and right ends of the second slide block 41 when sliding. Together with the first spring 51, it can also play the above positioning role. . In other embodiments, the first spring 51 can also be changed from a torsion spring to a compression spring, which can also make the second slide block 41 tightly abut both ends of the second slide groove 12 .

In addition, in this embodiment, a positioning plate 9 and a third spring 53 are also provided in the housing 1 for auxiliary positioning of each dial when assembling the lock body. Please refer to Figures 1a to 2b. One end of the positioning plate 9 is rotated on a spring shaft 14 in the housing 1, and the other end is provided with a positioning surface. The positioning surface is a flat surface, that is, the other end of the positioning plate 9 is flat. plate body. The third spring 53 is provided in the housing 1 and exerts an urging force on the positioning plate 9 toward the side of the first dial 31 , so that the positioning plate 9 can closely contact the side of each dial. In this embodiment, one side of the first peach 31 , the middle peach 33 and the outer peach 34 is provided with a planar positioning surface, which can abut against the positioning surface on the positioning plate 9 during assembly. Together, and at this time, the side surfaces of the first boss 61 and the second boss 62 are in contact with the unlocking platform 24, and the side surfaces of the third boss 63 are in contact with the limiting column 13, thereby quickly unlocking each dial. Peach is positioned accurately. Needless to say, changing the above positioning surface to other shapes, such as wavy, arc, etc., can also play a role in limiting the position of the peach. The third spring 53 is a torsion spring in this embodiment. In other embodiments, it can also be changed to a compression spring, which can also make the positioning plate 9 press against the side of the peach.

This embodiment also discloses a keyless door lock, which applies the above lock body structure. Among them, Figure 5a shows the structure of the keyless door lock from the perspective of the inside of the door, and Figure 5b shows the structure of the keyless door lock from the perspective of the outside of the door. In these two figures, both figures are hidden. The structure of the housing 1 is removed to show the connection relationship between the handle and the lock body structure; Figure 6a shows the exploded structure of the emergency unlocking structure in this embodiment from the perspective of the inside of the door, and Figure 6b shows The exploded structure of the emergency unlocking structure in this embodiment from the perspective of the outside of the door.

Please refer to Figures 5a-6b. The keyless door lock includes a first handle 71 and a second handle 72 provided on both sides of the lock body structure. One end of the first handle 71 is inserted into the square core hole in the middle of the first dial 31 and serves as a handle on one side of the door to realize the unlocking/reverse locking function; one end of the second handle 72 is inserted into the second dial. The square core hole in the middle part of the peach 32 is inserted into the square core hole of the middle peach 33 and the outer peach 34. As a handle on the outside side of the door, it can only be rotated to unlock the door when it is not locked. In another embodiment, the first handle 71 can also be inserted into the square core hole in the middle of the outer dial 34 and used as a handle on one side of the door to realize the unlocking/reverse locking function; and the second handle 72 One end of the handle is inserted into the square core hole of the middle peach 33 and the first peach 31. As a handle on the outside side of the door, it can only be rotated to unlock when it is not locked. The keyless door locks in the two embodiments can be respectively suitable for left-hand and right-hand opening doors.

In addition, in this embodiment, a transmission bar 73 that can rotate synchronously with the locking block 4 is also penetrated in the middle of the locking block 4. Both ends of the transmission bar 73 extend to the outside of the housing 1 and can be used for emergency unlocking and unlocking. Shows whether the lock body is in the locked state.

Specifically, a status needle 74 connected to the transmission bar 73 is provided on the side of the door lock close to the door. As shown in Figures 5a and 5b, the status needle 74 is fixedly connected to the transmission bar 73 and is rotated on the inside. On panel 75. When the sixth boss 66 abuts the third boss 63, the lock body is in a reverse-locked state, and the needle 74 in this state points to the first preset position; when the sixth boss 66 gradually leaves the third boss 63, The status needle 74 gradually points to the second preset position until the lock body is in an unlocked state, and the status needle 74 points to the second preset position. For example, red marks and green marks may be used to represent the first preset position and the second preset position respectively. When the status needle 74 points to the red mark, it means that the lock body is in the locked state, and the first handle 71 needs to be pressed down to release the locked state; when the status needle 74 points to the green mark, it means that the lock body is not in the locked state, and it needs to be Lift the first handle 71 to achieve reverse locking. By setting the status pin 74, it is convenient for the user to know whether the door lock is in a locked state, so that the door lock can be unlocked in a targeted manner.

In this embodiment, an emergency unlocking structure connected to the transmission bar 73 is provided on the side of the door lock close to the outside of the door. The emergency unlocking structure includes an emergency dial 77 , a connecting block 78 and a baffle 79 . The emergency dial 77 is rotatably mounted on the outer panel 76, and its outer end is provided with a groove. The user can use a plate-shaped tool to rotate the emergency dial 77. The outer panel 76 is provided with a through hole for accommodating the groove portion, so the user can turn the emergency switch 77 from the outside side of the door.

A protruding first clamping platform 81 is provided on the outer periphery of the emergency switch 77, and a first clamping slot 83 for accommodating the first clamping platform 81 is provided on the outer panel 76. The first clamping platform 81 can be placed on the first clamping platform 81. A card slot 83 slides inside. When the lock body is not locked, the first clamping platform 81 is in the middle position of the first clamping slot 83. When the lock body is locked, the first clamping platform 81 is in contact with one end of the first clamping slot 83. The end of the transmission bar 73 is provided with an outwardly protruding second clamping platform 82. An inner end of the emergency switch 77 is provided with a groove for accommodating the end of the transmission bar 73 and a third slot for accommodating the second clamping platform 82. The second clamping slot 84 and the second clamping platform 82 can slide in the second clamping slot 84 along with the transmission bar 73 . When the lock body is not locked, the second clamping platform 82 is in the middle position of the second clamping slot 84 . When the lock body is locked, the second clamping platform 82 abuts one end of the second clamping slot 84 . Therefore, when it is not locked, the user rotates the emergency switch 77 from the outside, so that the first clamping platform 81 can only contact the end of the first clamping slot 83. At this time, one end of the second clamping slot 84 abuts on the second clamping slot 83. On the clamping platform 82, the transmission bar 73 cannot be further rotated, so the lock body cannot be reverse-locked from the outside side of the door. When the lock body is locked, the second clamping platform 82 is in contact with one end of the second clamping groove 84, such as the left end in Figure 6a. At this time, the emergency dial 77 is turned counterclockwise in the figure. Rotate the transmission bar 73 counterclockwise to release the anti-lock. In other words, unlocking is only possible on the outside side of the door.

The connecting block 78 is sleeved on the end of the transmission bar 73. One end is rotatably located in the groove inside the emergency dial 77, and the other end is rotatably located in the groove outside the baffle 79 to limit the diameter of the end of the transmission bar 73. The swaying in the direction allows the transmission bar 73 to have only a degree of freedom in rotation, thereby improving the stability of the lock. The baffle 79 can limit the emergency dial 77 and the linkage block in the space between the baffle 79 and the outer panel 76, further improving the stability of the lock.

The above shows an emergency unlocking structure that can only release the reverse lock. In other embodiments, one end of the transmission bar 73 can also be provided in the through hole on the outer panel 76 as an emergency unlocking structure, and the transmission can be directly rotated during use. Item 73 can release the anti-lock.

This keyless door lock is especially suitable for indoor doors such as bathrooms, elderly rooms, and children's rooms. Its advantages are: the door lock has a simple structure, low cost, clear and concise linkage relationships, and the structure is not easily damaged; the lock body is easy to install regardless of the front or rear. It has high installation and practicality; the requirements for the handle structure are not high. Whether it is a long handle or a spherical handle, the process of locking, unlocking and reverse locking is extremely simple. For example, when using a long-handled handle, you can lift the door handle to lock it, and press the door handle to unlock it. After locking, emergency unlocking from the outside does not require special tools. A common screwdriver can be used to turn the door handle. Turn the knob to unlock. In addition, if the door is accidentally locked when the door is opened, the door can be automatically unlocked when the door is closed.
