Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically a door lock structure with a door opening state switching function. Background Technology

[0002] In the field of door lock technology, traditional door locks typically have fixed opening settings, meaning the left-opening, right-opening, or single-opening state is determined during manufacturing and cannot be flexibly adjusted according to actual usage needs. This means that when installing or replacing a door lock, users must precisely match the door's opening direction. If the lock's state does not match the door, a compatible lock must be purchased, increasing procurement costs, extending the installation period, and causing considerable inconvenience to users.

[0003] While some adjustable door locks can switch directions, their complex structure requires disassembling multiple components and necessitates specialized tools and technicians, making them difficult for ordinary users to perform independently. Furthermore, the limiting structure of these locks is often poorly designed, leading to issues such as jamming or directional deviation after switching. There is even a risk of damage to internal components due to excessive rotation, affecting the lock's lifespan and safety.

[0004] As users increasingly demand flexibility and convenience in home furnishings, the shortcomings of traditional door locks in terms of status adaptability, ease of operation, and structural stability have become increasingly apparent. Therefore, developing a door lock structure that can quickly switch between open and closed states, is easy to operate, and has a stable structure is crucial to overcoming the deficiencies of existing technologies, meeting usage needs in different scenarios, and improving user experience. In light of this, we propose a door lock structure with an open / closed state switching function. Utility Model Content

It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0021] Please see Figure 1 - Figure 9 As shown, this utility model provides a technical solution: A door lock structure with a door open state switching function includes: The front panel 1 has a bolt hole in the middle and a door handle 2 is rotatably installed inside the bolt hole. A lock cylinder hole 3 is provided on the front panel 1 and directly below the bolt hole. Two bolt holes 4 are symmetrically arranged on the upper part of the front panel 1. A door lock body 5 is fixedly installed on the inner side wall of the front panel 1 by bolts. An adjustment buckle 6 is rotatably installed on the side of the door lock body 5 away from the front panel 1 and coaxial with the bolt hole. Movable grooves 7 are symmetrically arranged on the upper and lower sides of the adjustment buckle 6 on the door lock body 5. Two locking holes 8 are diagonally arranged on the door lock body 5 and around the two movable grooves 7. The adjusting buckle 6 has a circular structure. A first locking block 9 is provided at the lower part of the circumference of the adjusting buckle 6, and a paddle protrusion 10 is provided at the upper part of the circumference of the adjusting buckle 6. A second locking block 11 is provided on the circumferential side wall of the adjusting buckle 6 near the position of the first locking block 9. Both the first locking block 9 and the second locking block 11 have round holes. An adjusting bolt 12 is provided in the round hole of the first locking block 9 or the second locking block 11. The door handle 2 is inserted and engaged with the adjusting buckle 6. The door handle 2 has a left-open state, a right-open state, and a single-open state. A limiting component is installed inside the door lock body 5 and is used to constrain the rotation direction of the door handle 2.

[0022] In this embodiment, when the door handle 2 is positioned to the left and in the left-open state: The handle of the door handle 2 faces the left side of the front panel 1. The first locking block 9 is located directly below the paddle protrusion 10. An adjusting bolt 12 is installed in the internal thread of the round hole on the first locking block 9, and the end of the adjusting bolt 12 extends into the lower movable groove 7. At this time, the adjusting bolt 12 limits the adjusting buckle 6 by cooperating with the movable groove 7, preventing the adjusting buckle 6 from shifting during the rotation of the door handle 2, ensuring that the door handle 2 can only rotate stably in the left opening direction. At the same time, the limiting protrusion 18 in the limiting assembly is engaged with the limiting hole 20 on the door handle 2 under the elastic force of the spring 19, further constraining the rotation angle of the door handle 2 and preventing excessive movement.

[0023] In this embodiment, when the door handle 2 is positioned to the left and in a single-open state: The handle of the door handle 2 faces the left side of the front panel 1. The first locking block 9 is located directly below the paddle protrusion 10. The round hole on the second locking block 11 is aligned with the locking hole 8 at the lower left corner of the door lock body 5. An adjusting bolt 12 is installed in the internal thread of the round hole on the second locking block 11. The adjusting bolt 12 is threadedly engaged with the locking hole 8 at the lower left corner. After the adjusting bolt 12 fixes the second locking block 11 and the locking hole 8, the rotation of the adjusting buckle 6 is restricted to one direction, so that the door handle 2 can only move along the preset single-opening trajectory. That is, at this time, the door handle 2 cannot rotate relative to the position of the front panel 1. The limiting component works synchronously, and the limiting protrusion 18 is inserted into the corresponding limiting hole 20 to prevent the door handle 2 from rotating in other directions, thus achieving stable output of the single-opening function.

[0024] In this embodiment, when the door handle 2 is positioned to the right and in the right-open state: The door handle 2 faces the right side of the front panel 1. The first locking block 9 is located directly above the paddle protrusion 10. An adjusting bolt 12 is installed in the internal thread of the round hole on the first locking block 9, and the end of the adjusting bolt 12 extends into the upper movable groove 7. The engagement of the adjusting bolt 12 with the upper movable groove 7 effectively limits the adjusting buckle 6, ensuring that the door handle 2 does not deviate when it rotates in the right-opening direction. The insertion relationship between the limiting protrusion 18 and the limiting hole 20 in the limiting assembly is adjusted according to the rotation of the door handle 2, constraining the door handle 2 to move only in the right-opening direction and avoiding directional confusion.

[0025] In this embodiment, when the door handle 2 is positioned to the right and in a single-open state: The door handle 2 faces the right side of the front panel 1. The first locking block 9 is located directly above the paddle protrusion 10. The round hole on the second locking block 11 is aligned with the locking hole 8 at the upper right corner of the door lock body 5. An adjusting bolt 12 is installed in the internal thread of the round hole on the second locking block 11, and the adjusting bolt 12 is threadedly engaged with the locking hole 8 at the upper right corner. After the adjusting bolt 12 fixes the second locking block 11 and the locking hole 8 at the upper right corner, the rotation range of the adjusting buckle 6 is limited, so that the door handle 2 can only complete the door opening action in a single direction. The limiting component further enhances the stability of the single-open state and prevents directional deviation caused by misoperation through the corresponding engagement of the limiting protrusion 18 and the limiting hole 20.

[0026] In this embodiment, the limiting component includes: A rectangular groove 13 is formed on the inner side wall of the door lock body 5 and is coaxial with the pivot of the door handle 2. A circular groove 14 is formed on the inner side wall of the rectangular groove 13. An outer sleeve 15 is inserted and fixed in the circular groove 14. An annular block 16 is inserted and fixed in the outer sleeve 15. Multiple evenly distributed sliding grooves 17 are formed on the outer circumference of the annular block 16. Limiting protrusions 18 are slidably installed in the sliding grooves 17. The limiting protrusions 18 are provided on the side of the sliding groove 17 facing the outer sleeve 15. Multiple limiting holes 20 that match the limiting protrusions 18 are formed on the circumferential side wall of the pivot of the door handle 2. The limiting protrusions 18 and the limiting holes 20 are inserted and fitted. A cover 21 is inserted and installed in the rectangular groove 13 and is fixed to the door lock body 5 by bolts. The outer sleeve 15 is fixed in the rectangular groove 13 through the circular groove 14, providing an installation base for the annular block 16; the limiting protrusion 18 in the sliding groove 17 always tends to move closer to the pivot of the door handle 2 under the elastic force of the spring 19. When the door handle 2 rotates, the limiting protrusion 18 will slide in the sliding groove 17 with the rotation of the door handle 2 and engage with the limiting holes 20 at different positions, thereby limiting the rotation direction and angle of the door handle 2; the cover 21 is fixed in the rectangular groove 13 by bolts, sealing the opening of the rectangular groove 13 to prevent dust and impurities from entering and affecting the operation of the limiting component, while enhancing the overall structural stability.

[0027] In this embodiment, anti-slip protrusions 22 are symmetrically arranged on the inner circumference of the opening in the middle of the first locking block 9. A protective groove 23 is provided on the rotating shaft of the door handle 2 to cooperate with the anti-slip protrusions 22. The anti-slip protrusions 22 and the protective groove 23 are inserted into each other. The insertion and cooperation of the anti-slip protrusions 22 and the protective groove 23 enhances the connection strength between the door handle 2 and the adjusting buckle 6, so that the force when the door handle 2 rotates can be stably transmitted to the adjusting buckle 6, avoiding the failure of power transmission caused by relative sliding between the two, and reducing shaking during rotation, thus improving the smoothness of operation.

[0028] In this embodiment, the first locking block 9, the paddle protrusion 10, the second locking block 11, and the two anti-slip protrusions 22 are integrally formed with the adjusting buckle 6. The integrally formed structure reduces the assembly gap between components, lowers the risk of structural loosening due to assembly errors, improves the overall structural strength of the adjusting buckle 6, extends the service life of the components, reduces assembly steps, and improves production efficiency.

[0029] When using the door lock structure with door opening state switching function in this embodiment: When the door lock needs to be adjusted to the left-open position, first turn the handle of the door handle 2 toward the left side of the front panel 1 so that the first locking block 9 is directly below the paddle protrusion 10. Then screw the adjusting bolt 12 into the round hole of the first locking block 9 and ensure that its end extends into the lower movable groove 7. At this time, the limiting protrusion 18 in the limiting assembly is inserted into the limiting hole 20 of the door handle 2 under the action of the spring 19, which restricts the door handle 2 to only rotate to the left, thus completing the left-open state setting. That is, when the door handle 2 is in the left-side setting state, turning the door handle 2 downwards will open the door lock.

[0030] To switch to the left-side single-opening mode, keep the door handle 2 facing the left side of the front panel 1 and the first locking block 9 positioned directly below the paddle protrusion 10. Adjust the adjusting buckle 6 so that the round hole of the second locking block 11 is aligned with the locking hole 8 at the lower left corner of the door lock body 5. Screw the adjusting bolt 12 into the round hole of the second locking block 11 and thread it into the locking hole 8. At this time, the adjusting buckle 6 is fixed, and the door handle 2 cannot be rotated. The limiting component simultaneously constrains the rotation range, realizing the single-opening function when the door handle 2 is set to the left. At this time, the door lock can be opened by turning the lock cylinder with the key.

[0031] When adjusting to the right-open position, point the handle of the door handle 2 toward the right side of the front panel 1, so that the first locking block 9 is directly above the paddle protrusion 10. Screw the adjusting bolt 12 into the round hole of the first locking block 9 and extend it into the upper movable groove 7. The limiting component adjusts the insertion relationship between the limiting protrusion 18 and the limiting hole 20 as the door handle 2 turns, constraining the door handle 2 to move only in the right-open direction. That is, when the door handle 2 is in the right-side setting state, turning the door handle 2 downwards will open the door lock.

[0032] When switching to the right-side single-opening state, keep the door handle 2 facing the right side of the front panel 1 and the first locking block 9 positioned directly above the paddle protrusion 10. Adjust the adjusting buckle 6 so that the round hole of the second locking block 11 is aligned with the locking hole 8 at the upper right corner of the door lock body 5. Screw the adjusting bolt 12 into the round hole of the second locking block 11 and engage it with the locking hole 8. At this time, the door handle 2 cannot be rotated, and the limiting component helps to fix the rotation range. At this time, the door lock can be opened by turning the lock cylinder with the key.

[0033] In daily use, the door lock can be locked and unlocked by inserting a key into the lock cylinder mortise 3. The bolt pre-drilled hole 4 is used to fix the front panel 1 to the door. The limiting component continuously constrains the rotation angle of the door handle 2 through the cooperation of the limiting protrusion 18 and the limiting hole 20 to avoid excessive rotation. The insertion and cooperation of the anti-slip protrusion 22 and the protective groove 23 ensures stable power transmission between the door handle 2 and the adjusting buckle 6. The one-piece molded adjusting buckle 6 and its components improve the smoothness of operation and structural stability.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
