On one side of the rectangular tube, there are several plug holes, and on the other side, there is an adhesive layer. The lock head assembly includes a fixed seat. On one side wall of the fixed seat, there is a lock cylinder. Inside the lock cylinder, there is a receiving space, and at the bottom, there is a through hole. Inside the receiving space, there is a lock core. At the bottom of the lock core, there is a lock tongue. The other end of the lock tongue extends towards the bottom of the lock cylinder, passes through the through hole, and is inserted into the plug hole.
[0006] As a further description of the above solution, a slot is opened at a position near the bottom end of the lock cylinder, and a spring piece is arranged in the slot. One end of the spring piece is slidably connected to the inside of the lock core.
[0007] As a further description of the above solution, a long slot is opened on the outer wall of the lock cylinder, and a fixed pin is arranged inside the long slot. One end of the fixed pin passes through the long slot and is fixedly connected to the outer wall of the lock core.
[0008] As a further description of the above solution, a spring is sleeved on the lock tongue. One end of the spring abuts against the bottom of the lock core, and the other end abuts against the bottom of the receiving space.
[0009] As a further description of the above solution, the plug holes are evenly distributed along the length direction on the rectangular tube.
[0010] As a further description of the above solution, the shape of the locking tongue matches the shape of the bolt hole, and the length of the locking tongue matches the depth of the bolt hole.
[0011] As a further description of the above solution, screw holes are respectively provided at the four corners of the fixed seat.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] By means of the cooperation between the locking tongue and the bolt hole on the rectangular tube, the present utility model can firmly limit the opening degree of the sliding window or door, effectively prevent safety accidents caused by excessive opening of the window or door due to accidental collision or strong wind, etc., and provide reliable safety protection for users; the elastic piece provided on the lock core cooperates with the slotted opening provided on the lock cylinder, so that the locking tongue is not easily retracted accidentally after being inserted into the bolt hole, ensuring the stability of the limiting state and further enhancing the safety; a back glue layer is provided on one side of the rectangular tube, and screw holes are provided at the four corners of the fixed seat of the lock head assembly, and the installation process is simple and efficient.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a translation door and window limit lock, including a rectangular tube 1 and a lock head assembly. On one side of the rectangular tube 1, there are several pin holes 2, which are evenly distributed along the length direction on the rectangular tube 1. On the other side, there is an adhesive layer 3. The lock head assembly includes a fixed seat 4. At the four corners of the fixed seat 4, there are screw holes 7 respectively. On one side wall of the fixed seat 4, there is a lock cylinder 5. Inside the lock cylinder 5, there is a receiving space, and at the bottom, there is a through hole 11. Inside the receiving space, there is a lock core 6. At the bottom of the lock core 6, there is a lock tongue 8. The other end of the lock tongue 8 extends towards the bottom of the lock cylinder 5 and passes through the through hole 11. The shape of the lock tongue 8 matches the shape of the pin hole 2, and the length of the lock tongue 8 matches the depth of the pin hole 2. The design of the adhesive layer 3 enables the rectangular tube 1 to be smoothly pasted on the frame of the translation door and window. The fixed seat 4 is installed on another door and window frame through the screw holes 7, and the installation is extremely convenient; the design of the lock tongue 8 and the pin hole 2 enables the lock tongue 8 to be inserted into any pin hole 2 to limit the opening range of the door and window.
[0020] Specifically, as Figure 2 shown in Figure 3 : At a position near the bottom end of the lock cylinder 5, there is a slot 9. Inside the slot 9, there is a spring piece 10. One end of the spring piece 10 is slidably connected to the inside of the lock core 6. Press the lock core 6, and the lock core 6 moves downward under the action of the pressure. When the lock tongue 8 gradually inserts into the pin hole 2 on the rectangular tube 1, at this time, the spring piece 10 in the slot 9 at the position near the bottom end of the lock cylinder 5 pops out and gets stuck in the slot 9 to prevent the lock core 6 from rebounding, thereby realizing the limit of the translation door and window.
[0021] Specifically, as Figure 2 shown in : On the outer wall of the lock cylinder 5, there is a long slot 12. Inside the long slot 1, there is a fixed pin 13. One end of the fixed pin 13 passes through the long slot 12 and is fixedly connected to the outer wall of the lock core 6; a spring 14 is sleeved on the lock tongue 8. One end of the spring 14 abuts against the bottom of the lock core 6, and the other end abuts against the bottom of the receiving space.
[0022] When in use, when it is necessary to limit the translation door and window, move the door and window to the required opening degree, gently push the lock core 6 with your hand. During the pushing process, the lock core 6 drives the lock tongue 8 to move towards the pin hole 2. When the fixed pin 13 on the lock core 6 moves to the bottom end of the long slot 12, the lock tongue 8 passes through the through hole 11 at the bottom of the lock cylinder 5 and inserts into the pin hole 2 on the rectangular tube 1. At this time, the spring piece 10 in the slot 9 at the bottom end position of the lock cylinder 5 pops out and gets stuck in the slot 9 to prevent the lock core 6 from rebounding, thereby realizing the limit of the translation door and window; when it is necessary to release the limit of the translation door and window, insert the key into the lock core 6 and rotate it. The spring piece 10 retracts under the action of the lock core 6. At this time, after losing the limit of the spring piece 10, the elastic force of the spring 14 will push the lock core 6 and the lock tongue 8 upward until the fixed pin 13 moves to the top end of the long slot 12. At this time, the lock tongue 8 also moves away from the pin hole 2, and the opening and closing range of the door and window can be moved freely.
[0023] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
