Detailed Description

The invention will be further illustrated with reference to specific embodiments:

referring to fig. 1 and 2, the safety lock for a sliding window based on a ratchet wheel and gear rack structure comprises: lock frame 1, inboard rack 15, outside rack 3 and wedge slider 2.

The lock frame 1 includes a base 101 and a chute 102 disposed below the base 101, and the chute 102 and the base 101 are integrally formed.

An inner support plate 103, a middle support plate 104 and an outer support plate 105 are fixed on the top of the base 101 in parallel in sequence.

The inner support plate 103 is provided with an inner gear set 4, specifically, an inner first gear 5, an inner central gear 6 and an inner second gear 7, and the inner central gear 6 is engaged with the inner first gear 5 and the inner second gear 7, respectively.

The outer support plate 105 is provided with an outer gear set 14, specifically, an outer first gear 11, an outer sun gear 12 and an outer second gear 13, and the outer sun gear 12 is engaged with the outer first gear 11 and the outer second gear 13, respectively.

An inner side ratchet wheel 17 and an outer side ratchet wheel 8 are respectively arranged on two sides of the middle support plate 104, the inner side central gear 6 is coaxially connected with the inner side ratchet wheel 17, and the outer side ratchet wheel 8 is coaxially connected with the outer side central gear 12; thus, whether the inner ratchet wheel 17 is locked or not directly influences the operation of the inner gear set 4; whether the outer ratchet wheel 8 is locked or not directly influences the operation of the outer gear set 14; the inner and outer gear sets and the inner and outer ratchets are not affected.

An inner ratchet claw 16 is arranged on the middle support plate 104 positioned below the inner ratchet 17, and an outer ratchet claw 9 is arranged on the middle support plate 104 positioned below the outer ratchet 8; under the normal state, the inner ratchet pawl and the outer ratchet pawl are kept not to be contacted with the inner ratchet and the outer ratchet under the action of the springs.

An inner first ejector block 20 and an inner second ejector block 21 are arranged below the inner ratchet claw 16, and an outer first ejector block 18 and an outer second ejector block 19 are arranged below the outer ratchet claw 9.

The inner first top block 20 and the outer first top block 18 play a main locking role, and the inner second top block 21 and the outer second top block 19 are additionally arranged in the embodiment and used for assisting locking.

The inner first ejector block 20, the inner second ejector block 21, the outer first ejector block 18 and the outer second ejector block 19 all penetrate through the base 101 and extend into the sliding groove 102, and each ejector block 10 is normally supported on the base 101 under the action of self gravity and is not in contact with a corresponding ratchet claw above.

Meanwhile, in order to realize asynchronous locking of the inner window and the outer window of the sliding window, the positions of the inner top block and the outer top block in the path direction of the sliding chute 102 are different (the positions of a ratchet wheel and a ratchet wheel claw are correspondingly arranged and the top blocks are matched in the directions), and the inner first top block 20, the inner second top block 21, the outer first top block 18 and the outer second top block 19 are arranged at the same positions side by side.

Referring to fig. 3, in the path direction of the sliding chute 102, the wedge-shaped sliding block 2 is pushed to contact the first outer top block 18 first, so that the outer ratchet pawl 9 can be pushed to lock the outer ratchet 8 first, and the outer gear set 14 is locked; the inner first crown 20 is initially unaffected (i.e. the operation of the inner ratchet 17 is not affected), and the outer ratchet 8 and the inner ratchet 17 are locked together only when the wedge 2 continues to advance to trigger the inner first crown 20.

The inner side rack 15 is positioned above the base 101 and meshed with the inner side first gear 5 and the inner side second gear 7; the outer rack 3 is located above the base 101 and is engaged with the outer first gear 11 and the outer second gear 13.

Wedge slider 2 install in spout 102 with spout 102 clearance fit, the spout 102 of this embodiment is the channel-section steel structure, and the cross-section design of wedge slider 2 becomes the T type, and the lower extreme of wedge slider 2 can stretch out the opening of spout 102 and be connected with the handle, the operation of being convenient for.

The wedge surface of the wedge-shaped sliding block 2 is matched with the lower end surface of each top block 10; only two outer jacking blocks or four jacking blocks 10 can be jacked simultaneously along with the movement of the wedge-shaped sliding block 2 along the sliding chute 102.

The specific installation operation mode of the invention is as follows:

the lock frame 1 is arranged at the position of a sliding groove at the bottom end of a window frame of a sliding window, an inner side window sash of the sliding window is arranged on an inner side rack 15, and an outer side window sash is arranged on an outer side rack 3; the trigger mode of the lockset is triggered by the pushing position of the wedge-shaped sliding block 2, when the wedge-shaped sliding block 2 is arranged at the outer side (not contacting any top block 10), the inner side window sash and the outer side window sash of the sliding window can be freely opened and closed; when wedge slide 2 moved to the intermediate gear (triggered two outside kicking blocks), inboard casement still can the free switch, and outside casement is then locked: when the wedge-shaped sliding block 2 moves to the deepest gear (the outer side top block and the inner side top block are both triggered to be jacked up), the inner side window sash and the outer side window sash are both locked.

The embodiments described above are described to facilitate an understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications can be made to the present embodiments and the generic principles defined herein may be applied to other embodiments without the use of the inventive faculty.
