Traditional window door locks are set up separately. One lock point is installed on one window frame, and one lock point is equipped with one control structure for independently controlling the opening and closing of the corresponding lock point. That is to say, one lock is set separately on one window frame, and this lock can only control the opening and closing of the corresponding window frame. Users can open and close any window separately. The number of lock parts is large, and the corresponding investment cost is high. Then the cost of the window is high, and the usage cost of users is also high, which is difficult to meet the usage needs of users in actual life. Moreover, the independent control of the two locks is more complicated in actual use and operation. And the traditional straight-up-and-down operation mode requires users to control the operation very hard, which is time-consuming and laborious, not easy to slide, and very inconvenient.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figure 1-7 Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model Embodiment
[0030] A double-lock-point outward-opening window door lock includes two upper fixing plates 1 and an outer shell 2. The two upper fixing plates 1 are respectively fixedly installed on the corresponding window frames. The outer shell 2 is detachably installed on the window frame. A lower fixing plate 6 fixedly installed on the window frame is arranged at the bottom of the upper fixing plate 1. A pulling handle 3 is movably installed inside the outer shell 2. One end of the pulling handle 3 is fixedly installed with a pulling wire 5. A sub-lock block 7 is rotatably installed between the upper fixing plate 1 and the lower fixing plate 6. A main lock block 8 adapted to the sub-lock block 7 is rotatably installed on one side between the upper fixing plate 1 and the lower fixing plate 6. One side of the sub-lock block 7 and the main lock block 8 are respectively clamped with a torsion spring one 9 and a torsion spring two 17. The ends of the torsion spring one 9 and the torsion spring two 17 away from the sub-lock block 7 and the main lock block 8 are clamped on the upper fixing plate 1. A fixed base 12 fixedly installed on the outer frame of the window is arranged below the lower fixing plate 6. A pin 16 adapted to the main lock block 8 is fixedly installed on the top of the fixed base 12. The end of the pulling wire 5 away from the pulling handle 3 is clamped on the sub-lock block 7 and the main lock block 8
[0031] The specific usage process is as follows: The user puts their hand into the outer shell 2 and then pulls the handle 3. When the handle 3 is pulled, the outer shell 2 flips to one side. At this time, the end of the handle 3 located outside the outer shell 2, that is, the end located inside the window frame, will lift upward, and then the cable 5 will be pulled. Since the cable 5 is composed of extension line 10 and extension line 11, the extension line 10 and extension line 11 will also move together inside the wire splitter 4. At the same time, the extension line 10 will pull the latch 13 to move, and the extension line 11 will pull the latch 14 to move. The latch 13 will pull the corresponding secondary lock block 7 to rotate between the upper fixing plate 1 and the lower fixing plate 6, and the latch 14 will pull the corresponding other secondary lock block 7 to rotate between the corresponding upper fixing plate 1 and the lower fixing plate 6. It should be noted that the secondary lock blocks 7 pulled by the latch 13 and the latch 14 rotate simultaneously, so only one explanation will be given below. When the secondary lock block 7 rotates, it will also twist the torsion spring 9, and at the same time, the secondary lock block 7 will drive the main lock block 8 to make a corresponding rotation. At the same time, the main lock block 8 will twist the torsion spring 17. Since the fixed base 12 and the latch 16 are fixedly installed on the outer window frame, the fixed base 12 and the latch 16 do not move. Therefore, when the main lock block 8 moves, under the reaction force of the latch 16, the upper fixing plate 1, the lower fixing plate 6, and the window frame, including all the components installed on the window frame, will move in the opposite direction, so that the window can be opened. It should be noted that since the latch 16 is stuck inside the main lock block 8, when the main lock block 8 rotates to unlock, the window frame will also make a corresponding small movement until the window is finally unlocked. During this process, the user can always control the window to open. At the same time, the opening process of the other window is the same. When the window is closed, because a bevel is provided on the side of the main lock block 8 facing the latch 16, when the window is closed, this bevel will first contact the latch 16. Under the control of the user, the main lock block 8 will be squeezed by the latch 16 and make a corresponding rotation until the upper fixing plate 1, the lower fixing plate 6, the main lock block 8, and the window frame are completely closed. At this time, the notch on the main lock block 8 will align with the latch 16. Among them, the secondary lock block 7 will also make a corresponding rotation, and then under the action of the torsion spring 17, the main lock block 8 will be reset, and then the latch 16 will be inserted into the inside of the main lock block 8 to achieve the locking of the window. Among them, the latch 13 and the latch 14 are respectively connected to the ends of the extension line 10 and the extension line 11, and the latch 13 and the latch 14 are respectively inserted into the two secondary lock blocks 7, so as to realize the movement of the two secondary lock blocks 7 by pulling the handle 3, providing convenience for the user's work. The limit elastic piece 15 is used to limit the secondary lock block 7 to prevent the secondary lock block 7 from moving randomly and ensure the stability after the window push-lock is locked, providing convenience for the user's work. The cable 5 is composed of the extension line 10 and the extension line 11. That is to say, the extension line 10 and the extension line 11 are braided into the cable 5, and the ends braided together are connected to the handle 3.The two separated ends are connected to the two auxiliary lock blocks 7, that is, the extension line 10 and the extension line 2 11 are respectively connected to the two auxiliary lock blocks 7, thereby ensuring the normal operation of the window and door lock and providing convenience for the user's work.
[0032] Therefore, a double-locking-point window and door lock structural design is adopted, and the two locking points are respectively arranged on the two window frames, so as to realize the individual locking and opening of the window frames, and also the simultaneous locking and opening of the two window frames, thereby providing users with more and more flexible options to meet the various usage needs of users in daily life, and the cost investment is also low. Compared with the straight up and down operation mode, the lever operation mode adopted in this solution is more labor-saving and convenient, which provides convenience for users' work.

[0035] One end of the extension line 10 is fixedly connected to a bayonet pin 13 inserted into the secondary locking block 7 at a corresponding position, and one end of the extension line 2 11 is fixedly connected to a bayonet pin 2 14 inserted into the secondary locking block 7 at a corresponding position.
