Description

Technical Field

[0001] This utility model relates to a lock, particularly a linkage reset impact lock. Background Technology

[0002] Chinese patent CN220869049U discloses an impact rotary lock, including a lock shell, a lock cylinder, and a bolt. The lock shell has a mounting hole, and the lock cylinder is inserted downward into the mounting hole. The lock cylinder is axially positioned relative to the mounting hole and rotates relative to the mounting hole. The upper end of the lock cylinder serves as the working end of the key, and the lower end extends out of the lock shell and is fixedly connected to the bolt. The rotary lock also includes a torsion spring, which is sleeved on the lock cylinder and located in the mounting hole. One end of the torsion spring is fixed to the lock shell, and the other end is fixed to the lock cylinder. The bolt includes a guide arc surface. When locked, pushing the door panel towards the door frame causes the guide arc surface of the bolt to press against the door frame. The bolt is forced to rotate against the torsion force of the torsion spring. After the door panel is closed, the bolt rotates in the opposite direction to the lock groove in the door frame under the action of the torsion spring.

[0003] The aforementioned patent has two drawbacks. First, since the impact rotary lock is installed on the door, the impact of the door hitting the door frame will cause slight deformation of the position of the impact rotary lock relative to the door, especially the bolt relative to the door. Over time, this can lead to the bolt's guide arc surface pressing against the door frame, preventing the lock cylinder from rotating and causing the entire impact rotary lock to fail. Second, the aforementioned impact rotary lock can only be installed on lighter doors. For heavier doors, the impact between the door and the door frame will damage the impact rotary lock. Furthermore, if more than one impact rotary lock is installed on the same door, the impact rotary locks will not rotate simultaneously. Utility Model Content

Detailed Implementation

[0031] like Figures 1 to 8As shown, the door frame 8 is fixed to the vehicle body 6, and one end of the door 9 is hinged to the vehicle body 6 (not shown). A sealing gasket 4 is also installed on the door frame 8 corresponding to the other end of the door 9. The linkage reset impact lock is installed on the vehicle body 6 outside the door frame 8 at the other end of the door 9. The linkage reset impact lock of this utility model includes: two lock bodies 1, two rotating plates 3, a fisheye rod end joint bearing pull rod 5, and a knob indexing plunger 7. The lock body 1 includes: a lock rod 12, a lock tongue 14, a lock sleeve 25, and a torsion spring 20. The lock tongue 14 is fixed to the upper end of the lock rod 12. There is a protruding impact guide arc surface 42 on the outer circumference of the lock tongue 14. The impact guide arc surface 42 extends to the top of the door frame 8. The lock sleeve 25 is fitted onto the lock rod 1 below the lock tongue 14. 2. The upper end of the lock sleeve 25 is fixed to the lock rod 12 by a second pin 22 passing through the lock rod 12. The torsion spring 20 is installed in the lock sleeve 25 between the lock rod 12 and the lock sleeve 25. One end of the torsion spring 20 is fixed to the lock rod 12 and the other end is fixed to the lock sleeve 25. The two lock bodies 1 are mounted side by side on the body 6 along the width direction of the door frame 8. The lower ends of the two lock sleeves 25 are inserted into the body 6 respectively. The upper end of the body 6 rests on the step of the lock sleeve 25. The anti-loosening washer 17 and the third locking nut 18 are screwed into the lock sleeve 25 from the lower end of the lock rod 12 respectively. The upper end of the anti-loosening washer 17 rests on the lower end of the body 6 respectively. The third locking nut 18 is fixed to the lock sleeve 25 by the pin 15. One end of each of the two rotating plates 3 is fixed to the locking rod 12 below the two locking sleeves 25 by clamps 2. The other ends of the two rotating plates 3 are respectively hinged to the two ends of the fisheye rod end joint bearing pull rod 5. The handle 10 is mounted on the locking rod 12 at the lower end of one of the rotating plates 3. The knob indexing plunger 7 is inserted into the center of one of the rotating plates 3. A nut (not shown) is welded at the corresponding position on the body 6.

[0032] like Figure 6 and Figure 5As shown, the locking rod 12 consists of a first locking rod 31, a second locking rod 32, a third locking rod 33, and a fourth locking rod 34 from top to bottom. The diameter of the third locking rod 33 is larger than the diameters of the first locking rod 31, the second locking rod 32, and the fourth locking rod 34. The diameter of the first locking rod 31 is equal to the diameter of the second locking rod 32. The first locking rod 31 is a threaded cylinder with two symmetrical longitudinal sections 38. The locking tongue 14 has a locking tongue hole 41 in the center, and the cross-section of the locking tongue hole 41 corresponds to the cross-section of the first locking rod 31. The second locking nut 23 is screwed into the first locking rod 31 and fixed to the longitudinal section 38 of the first locking rod 31 by a pin 15. The locking tongue 14 is inserted into the first locking rod 31 at the upper end of the second locking nut 23. The first locking nut 13 is screwed into the first locking rod 31 at the upper end of the locking tongue 14 and fixed to the longitudinal section 38 of the first locking rod 31 by a pin 15. A first pin hole 36 is opened radially on the first locking rod 31 above the first locking nut 13. The first pin 11 is inserted into the first pin hole 36 to fix the locking tongue 14 to the first locking rod 31. The third locking rod 33 is a cylindrical rod with two spaced first transverse grooves 19 along its length. Slip rings 21 are installed in the first transverse grooves 19 to facilitate the rotation between the locking rod 12 and the locking sleeve 14.

[0033] like Figure 6 As shown, the fourth locking rod 34 is a polygonal rod with two or three spaced second horizontal grooves 35 along its length. One end of the rotating plate 3 and the handle 10 have polygonal holes that mate with the polygonal rod. The rotating plate 3 and the handle 10 are respectively fitted onto the polygonal rod. The clamps 2 are respectively installed in the second horizontal grooves 35, fixing the rotating plate 3 and the handle 10 to the fourth locking rod 34.

[0034] like Figure 7 and Figure 5 As shown, the locking sleeve 25 is fitted on the outer side of the second locking rod 32 and the outer side of the third locking rod 33. The torsion spring 20 is fitted on the second locking rod 32. The locking sleeve 25 consists of an upper locking sleeve 26 and a lower locking sleeve 27 from top to bottom. The outer diameter of the upper locking sleeve 26 is larger than the outer diameter of the lower locking sleeve 27. A step is formed between the upper locking sleeve 26 and the lower locking sleeve 27. The lower locking sleeve 27 is a threaded cylindrical shell with at least four symmetrical longitudinal sections 39 on the outer side of the cylindrical shell. Two limiting blocks 16 are symmetrically fixed to the upper end of the upper locking sleeve 26. A second pin hole 37 is opened at the upper end of the second locking rod 32. The second pin 22 passes through the second pin hole 37 and is blocked between the two limiting blocks 16 at the upper end of the locking sleeve 25. There are also threads on the outer side of the two limiting blocks 16. The lock cover 24 is screwed into the threads on the outer side of the two limiting blocks 16. The upper body 6 is fixed to the lower locking sleeve 27 by the aforementioned step, the third locking nut 18 and the pin 15.

[0035] like Figure 8 As shown, on the outer circumferential surface of the latch 14, there are also: a guide surface 43 and a fastening groove 44. The impact guide arc surface 42 is connected to the guide surface 43 and the fastening groove 44 in sequence. The guide surface 43 is an inclined surface that slopes upward from the lower end of the impact guide arc surface 42 and is recessed into the latch 14. The fastening groove 44 is connected to the end of the guide surface 43 and is a groove recessed into the latch 14. After the door 9 collides with the impact guide arc surface 42, the fastening groove 44 and the guide surface 43 turn back to the outside of the door frame 8.

[0036] The distance between the lower end of the latch 14 and the upper end of the lower lock sleeve 27 is the thickness occupied by the door 9 when it is in the closed state. By adjusting the positions of the first locking nut 13 and the second locking nut 23, the distance between the lower end of the latch 14 and the upper end of the lower lock sleeve 27 can be adjusted to accommodate different door 9 thicknesses. The distance between the lower end of the upper lock sleeve 26 and the third nut 18 is the thickness of the fixed body 6.

[0037] When closing door 9, first pull the knob indexing plunger 7 out of the nut. After door 9 falls, it first hits the two latches 14 extending out of the door frame 8, and then hits the guide arc surface 42 and squeezes against door 9. The latches 14 overcome the torque of the torsion spring 20 and turn back to the outside of the door frame 8. After door 9 is closed, turn the handle 10. Under the combined action of the reaction force of the torsion spring 20 and the handle 10, the latches 14 rotate in the opposite direction to the outside of door 9, and door 9 is locked.

[0038] When the door 9 is opened, the handle 10 is turned, and the two rotating plates 3 and the fisheye rod end joint bearing pull rod 5 simultaneously drive the two locking rods 12 to rotate synchronously. The locking tongue 14 overcomes the torque of the torsion spring 20 and rotates back to the outside of the door frame 8. After the door 9 is opened, the locking tongue 14 will rotate to the top of the door frame 8 under the reaction force of the torsion spring 20. Then, the knob indexing plunger 7 is inserted into the nut to prevent the linkage reset impact lock from malfunctioning when the windproof cover or other parts are removed.

[0039] The knob indexing plunger 7 and the eye rod end spherical bearing pull rod 5 are mechanical parts that can be purchased in automation accessories.
