Description

Technical Field

[0001] This utility model relates to the field of door lock device technology, and in particular to a lock and a door. Background Technology

[0002] In the manufacturing and distribution of lock products such as mechanical door locks, the efficiency and cost of packaging, warehousing, and logistics are key factors affecting large-scale production and supply chain management. Currently, common door lock devices on the market include door handles and panels. To accommodate installation on the side of the door, the panel is usually designed as a vertical installation structure; while the door handle is usually designed as a horizontally extending structure to meet ergonomic requirements.

[0003] Existing door lock devices are typically transported with the panel and handle assembled. During transport packaging, the vertical structure of the panel and the horizontal structure of the handle together occupy a large amount of irregular space, creating huge "ineffective gaps" and making the overall packaging volume enormous. This not only leads to an increase in the amount of packaging materials used, but more seriously, it significantly reduces space utilization in standardized transport units such as containers and cargo containers, reducing the number of products that can be transported per unit volume, directly driving up the logistics and transportation costs of door lock devices.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0024] Please refer to Figures 1-4 A lock according to an embodiment of the present invention includes: Panel 10; The door handle includes a handle 12 and a handle rod 11 that passes through the panel 10. The first end of the handle rod 11 is located inside the panel 10 and has a limiting groove 13. The second end of the handle rod 11 is connected to the first end of the handle 12. The elastic reset assembly includes a return piece 14, which is provided with a limiting block 15 that is adapted to the limiting groove 13. The limiting block 15 is embedded in the limiting groove 13 so that the return piece 14 rotates synchronously with the door handle. The positioning piece 16 is detachably connected to the inside of the panel 10. When the handle 12 is rotated to the vertical position, the positioning piece 16 engages with the return piece 14 to limit the rotation of the handle bar 11 and the return piece 14, keeping the handle in a vertical position parallel to the panel 10.

[0025] Before packaging and shipping, the door handle is rotated to a vertical position parallel to the panel 10. At this time, the return piece 14, which is linked to the handle, also rotates to a specific position. Then, the positioning piece 16 is installed inside the panel 10 and locks the return piece 14, thereby overcoming the restoring force of the elastic reset component and firmly locking the handle in a vertical position. This significantly reduces the packaging volume, improves the utilization rate of transportation space, and directly reduces the logistics cost per unit. Upon arrival at the user's location, simply removing the positioning piece 16 allows the handle to automatically return to a horizontal position under the action of the elastic component, achieving a balance between transportation economy and ease of use.

[0026] According to some embodiments of the present invention, the return piece 14 includes an extension block 18. When the door handle is rotated to a vertical position, the extension block 18 is directly opposite the positioning piece 16. The positioning piece 16 has a positioning groove on the side facing the extension block 18, and part or all of the extension block 18 is limited to the positioning groove.

[0027] When the door handle is rotated to the vertical position, the extension block 18 of the return plate 14 rotates to the position directly opposite the positioning plate 16. At this time, the positioning groove on the positioning plate 16 partially or completely engages with the extension block 18, preventing the return plate 14 and the handle rod 11 from continuing to rotate, and firmly locking the handle in the vertical position.

[0028] According to some embodiments of the present invention, the positioning groove is an arc-shaped groove 17, and the two side walls of the arc-shaped groove 17 abut against the extension block 18 at non-lowest point positions.

[0029] The two side walls of the arc-shaped groove 17 form a tight abutment with the two sides of the extension block 18. This structure effectively prevents the extension block 18 from sliding due to the elastic reset force through the mechanical limiting effect of the two side walls, maintaining the handle in a vertically locked state; when unlocking is required, only the positioning piece 16 needs to be removed, the restriction of the arc-shaped groove 17 on the extension block 18 is immediately released, and the elastic reset component can drive the handle to automatically reset to the horizontal use state.

[0030] According to some embodiments of the present invention, the lock also includes a bolt 20, a through hole on the positioning plate 16, a protrusion 19 on the inner side of the panel 10, a threaded hole on the protrusion 19, and the bolt 20 passes through the through hole and is threadedly connected to the threaded hole.

[0031] The through hole on the positioning piece 16 is aligned with the threaded hole on the inner protrusion 19 of the panel 10. The bolt 20 passes through the through hole and is screwed into the threaded hole to fasten the positioning piece 16 to the panel 10. To remove it, simply rotate the bolt 20 in the opposite direction.

[0032] According to some embodiments of the present invention, the lock also includes a torsion spring 21. A fixing member is provided on the inner side of the panel 10. The torsion spring 21 is sleeved on the handle 11, and its first end abuts against the fixing member and its second end abuts against the return piece 14. The torsion spring 21 is used to provide a restoring force when the handle 12 is rotated to a horizontal state.

[0033] When the door handle is rotated to the vertical locking state, the torsion spring 21 sleeved on the handle rod 11 is compressed and deformed. Its first end forms a stable fulcrum through the fixing member, and the second end directly presses against the return plate 14, so that the torsion spring 21 accumulates elastic potential energy. After the positioning plate 16 is removed and the mechanical limit on the return plate 14 is released, the restoring force accumulated by the torsion spring 21 is immediately released, driving the return plate 14 to automatically rotate the handle to the horizontal use state.

[0034] According to some embodiments of the present invention, the fixing member includes a first fixing block 22 and a second fixing block 23. The first fixing block 22 and the second fixing block 23 are respectively disposed on the left and right sides of the panel 10. When the first end of the torsion spring 21 abuts against the first fixing block 22, the torsion spring 21 is used to provide a restoring force to the second end of the handle 12 when it rotates to the left. When the first end of the torsion spring 21 abuts against the second fixing block 23, the torsion spring 21 is used to provide a restoring force to the second end of the handle 12 when it rotates to the right.

[0035] By using the split left-right layout of the first fixing block 22 and the second fixing block 23, the direction of the restoring force of the torsion spring 21 can be flexibly adjusted: when the first end of the torsion spring 21 abuts against the first fixing block 22 on the left, its elastic potential energy drives the handle to rotate and reset to the second end facing the left; and when the first end of the torsion spring 21 reverses direction and abuts against the second fixing block 23 on the right, the direction of the restoring force is switched to drive the handle to rotate to the second end facing the right, which is suitable for quick adaptation to left-opening or right-opening door scenarios.

[0036] According to some embodiments of the present invention, the lock also includes a retaining spring 24, and the handle 11 has a retaining groove. The retaining spring 24 is located on the side of the return piece 14 away from the handle 12 and is fitted into the retaining groove.

[0037] During assembly, the retaining spring 24 is fitted into the pre-set groove in the handle 11. At this time, the retaining spring 24 is located on the side of the return piece 14 away from the handle 12, forming a mechanical blocking surface. When the handle is rotated or subjected to external force, the retaining spring 24 effectively prevents the return piece 14 from moving or falling off along the handle 11 axis through its tight fit with the groove.

[0038] According to some embodiments of the present invention, the lock also includes a square bar 25 and a spring 26. The handle rod portion 11 is provided with a hollow cavity. The spring 26 is sleeved on the square bar 25. The first end of the square bar 25 is limited to the cavity. The second end of the square bar 25 is provided with a connecting block 27. The two ends of the spring 26 respectively abut against the connecting block 27 and the handle rod portion 11.

[0039] One end of the square rod 25 is inserted into the hollow cavity of the handle 11, and the other end is inserted into the lock body, connected to the actuating mechanism that drives the bolt extension and retraction. Because the square rod 25 has a square cross-section, the handle 11 and the square rod 25 fit tightly together, achieving synchronous rotation. When the door handle is rotated, torque is transmitted almost without loss to the mechanism inside the lock body through the square rod 25, thereby driving the bolt to retract and opening the door. The spring 26 is sleeved on the outside of the square rod 25, located between the connecting block 27 at the end of the handle 11 and the square rod 25, and is used to provide axial pressure to eliminate gaps in the transmission system, thereby improving the operating feel and eliminating abnormal noise.

[0040] According to some embodiments of the present invention, the handle 12 is provided with anti-slip texture or anti-slip protrusion.

[0041] When the user rotates the handle 12, the fine grooves or three-dimensional structure of the anti-slip texture can effectively increase the friction between the palm and the handle 12, avoiding slippage caused by sweaty, wet hands or unstable force.

[0042] A door according to an embodiment of the present invention includes a door body and a lock, the lock being detachably mounted on the door body.

[0043] During assembly, the entire lock is fixed to the preset installation position on the door using bolts 20, clips, or quick-release structures, achieving quick positioning and stable connection. When the lock malfunctions or needs to be upgraded, there is no need to damage the door structure; the entire lock can be replaced simply by removing bolts 20, clips, or quick-release structures, significantly reducing maintenance costs and time.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
