[0032] refer to Figures 1 to 4 As shown in the figure, a quick-install door lock structure is shown. The quick-install door lock structure comprises: a U-shaped lock 3, a ring buckle 4 and a lock core rod 7.
[0033] The U-shaped lock 3 is fixed horizontally on the wallboard 1, and the ring buckle 4 is hung on the U-shaped lock 3 via a short connecting rod 9, and the ring buckle can rotate around the short connecting rod in the U-shaped lock. The two ends of the short connecting rod 9 are respectively connected to the rod bodies on both sides of the U-shaped lock 3, and the short connecting rod 9 is arranged close to the bottom rod body of the U-shaped lock 3.
[0034] The lock core rod 7 is horizontally fixed on the door panel 5. When the door panel 5 is in a closed state, one end of the lock core rod 7 is located at the bottom side of the U-shaped lock 3 and between the ring buckle 4 and the wall panel 1.
[0035] Preferably, the distance from the short connecting rod 9 to the end of the U-shaped lock 3 is greater than the outer diameter of the ring buckle 4 ; the distance from the short connecting rod 9 to the bottom rod body of the U-shaped lock 3 is less than the inner diameter of the ring buckle 4 .
[0036] Preferably, a locking plate 2 is provided between the wall panel 1 and the U-shaped lock 3, and the U-shaped lock 3 is fixed on the locking plate 2. Further, the U-shaped lock 3 and the locking plate 2 are an integrally formed structure or welded. Further, the locking plate 2 is fixed on the wall panel 1 by screws 8.
[0037] Preferably, the short connecting rod 9 is connected to the rod bodies on both sides of the U-shaped lock 3 by welding.
[0038] Preferably, the lock core rod 7 is connected and fixed to the door panel 5 via a lock core plate 6. Further, the lock core rod 7 and the lock core plate 6 are an integrally formed structure or are welded.
[0039] Preferably, the lock core plate 6 is fixedly connected to the door panel 5 via screws 8 .
[0040] Preferably, the U-shaped lock 3, the ring buckle 4 and the lock core rod 7 are steel structures.
[0041] Example
[0042] The lock plate 2 is fixed to the wall plate 1 by screws 8 at four corners, a horizontally placed U-shaped lock 3 is welded to the outer surface of the lock plate 2, the lock tail end surface of the U-shaped lock 3 coincides with the surface of the lock plate 2, and a short connecting rod 9 is welded inside the lock head. The ring buckle 4 is inserted into the short connecting rod 9, and the ring buckle 4 can rotate around the short connecting rod 9 in the U-shaped lock 3.
[0043] The lock core plate 6 is also fixed to the door panel 5 by screws 8 at the four corners. A horizontally placed lock core rod 7 is welded to the outer plate surface of the lock strike plate 2. The axis of the lock core rod 7 is parallel to the end surface of the lock strike plate 2. Half of the rod is close to the end surface of the plate, and the other half extends out of the end surface of the door panel 5.
[0044] When the door lock is in the open state Figure 1 As shown, at this time, the lock core rod 7 and the U-shaped lock 3 are in a separated state.
[0045] When the door is about to close, Figure 4 As shown, the lock core rod 7 approaches the U-shaped lock 3. When the lock core rod 7 contacts the ring buckle 4, it pushes the ring buckle 4 to move, and the ring buckle 4 begins to rotate clockwise around the short connecting rod 9. When the ring buckle 4 rotates to the highest point, the bottom end of the ring buckle 4 is higher than the top of the lock core rod 7, and the lock core rod 7 can just pass under the ring buckle 4. After that, the lock core rod 7 continues to move forward and separates from the ring buckle 4, and the ring buckle 4 is reset under the action of gravity.
[0046] After the door lock is closed, the door panel 5 is pushed inward from the outside of the door, and the lock core rod 7 starts to move in the opposite direction toward the ring buckle 4. When the lock core rod 7 contacts the ring buckle 4 and pushes the ring buckle 4 to start rotating counterclockwise, the rotation of the ring buckle 4 is blocked due to the obstruction of the closed structure of the lock tail of the U-shaped lock 3, causing the lock core rod 7 to stop moving further.
[0047] When the door lock is to be opened, the ring buckle 4 must be lifted upward to make it at the highest point, and then the door panel 5 is pulled to open it.
[0048] When installing the quick-install door lock structure of the utility model, first place the ring buckle 4 in the U-shaped lock 3, then weld the internal short connecting rod 9, so that the ring buckle 4 is sleeved on the short connecting rod 9, and then weld the U-shaped lock 3 and the lock core rod 7 to the lock plate 2 and the lock core plate 6 respectively, and finally fix the lock plate 2 and the lock core plate 6 to the wall plate 1 and the door plate 5 respectively by screws 8. When installing the lock core plate 6, pay attention that the top height of the lock core rod 7 is slightly lower than the bottom height of the U-shaped lock 3.
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
