Description

Technical Field

[0001] The utility model relates to a window and door bolt structure, belonging to the technical field of window and door bolts. Background Art

[0002] A window and door bolt is a common safety device used to fix windows and doors to prevent illegal intrusion or accidental opening. Window and door bolts are usually made of metal and have a movable rod or pin that can be inserted into a hole fixed on the door frame or window frame.

[0003] For the existing window and door bolts, an outer dial is used to adjust the position of the bolt head so that it can be inserted into or disengaged from the corresponding socket on the window and door. However, during the process of using the dial to adjust the position of the bolt head, the sliding piece connected to the bolt head will be lifted, and the width of the window and door bolt during movement is large, which also leads to the corresponding increase in the width of the window and door, resulting in waste of materials. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that during the process of using a dial to adjust the position of the bolt head of the existing window and door bolt, the sliding piece connected to the bolt head will be lifted, and the width of the window and door bolt during movement is large.

[0005] To solve the above problems, the utility model provides a window and door bolt structure, including a connecting seat. An adjusting hole is provided in the connecting seat. A limiting mechanism is rotatably connected in the adjusting hole through two rotating rods. The two rotating rods are located on both sides of the limiting mechanism. The limiting mechanism includes a bolt head, a sliding piece, and a dial. The dial is rotatably connected to one end of the sliding piece through a rotating shaft. The sliding piece is L-shaped and the other end is fixedly connected to the bolt head. A socket adapted to the bolt head is provided at one end of the connecting seat. A U-shaped spring is provided on the rotating shaft. Both ends of the U-shaped spring are respectively sleeved outside the two rotating shafts, and the middle section of the U-shaped spring is in contact with the sliding piece.

[0006] Further: A plurality of fixing holes are evenly distributed in the connecting seat.

[0007] Further: The sliding piece is elastic.

[0008] Further: A placement groove adapted to the dial is provided in the adjusting hole.

[0009] The advantages of the utility model compared with the prior art are as follows:

[0010] By providing a U-shaped spring adapted to the sliding piece and the rotating shaft, the utility model can limit the sliding piece, avoid the situation that the sliding piece is lifted when using the dial without affecting the movement of the bolt head, and effectively reduce the movement width and volume of the window and door bolt. Description of the Drawings

[0011] The accompanying drawings are used to provide a further understanding of the present utility model and form a part of the specification. Together with the embodiments of the present utility model, they are used to explain the present utility model and do not constitute a limitation to the present utility model. In the accompanying drawings:

[0016] 1. Connecting seat; 11. Adjusting hole; 12. Rotating rod; 13. Insertion hole; 14. Placing groove; 2. Limiting mechanism; 21. Bolt head; 22. Sliding piece; 23. Pushing piece; 24. Rotating shaft; 25. U-shaped spring. Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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.

[0018] Combined with the attached Figures 1-3The utility model provides a door and window latch structure, including a connecting seat 1, wherein the connecting seat 1 is provided with a plurality of evenly distributed fixing holes for fixing the latch structure and the door and window, wherein the connecting seat 1 is provided with an adjusting hole 11, wherein the adjusting hole 11 is rotatably connected to a limiting mechanism 2 through two rotating rods 12, wherein the two rotating rods 12 are located on both sides of the limiting mechanism 2, wherein the limiting mechanism 2 includes a latch head 21, an elastic sliding sheet 22, and a paddle 23, wherein the paddle 23 is rotatably connected to one end of the sliding sheet 22 through a rotating shaft 24, wherein the sliding sheet 22 is L-shaped and the other end is fixedly connected to the latch head 21, wherein one end of the connecting seat 1 is provided with a socket 13 adapted to the latch head 21, wherein the rotating shaft 24 is provided with a U-shaped spring 25, wherein the U-shaped spring 25 The two ends are respectively sleeved on the outside of the two rotating shafts 24, and the middle section of the U-shaped spring 25 is in contact with the sliding piece 22. When in use, the paddle 23 is turned to rotate around the rotating rod 12, thereby driving the sliding piece 22 to move through the rotating shaft 24, so that the pin head 21 can move in the insertion hole 13. In this process, the U-shaped spring 25 squeezes the sliding piece 22 to prevent the sliding piece 22 from being forced to pop out of the connecting seat 1, thereby effectively reducing the active width and volume of the door and window latch, and avoiding the door and window latch occupying too large a width, resulting in the need to increase the door and window width accordingly, resulting in material waste. A placement groove 14 adapted to the paddle 23 is provided in the adjustment hole 11, which is used to limit the active range of the paddle 23 to control the position of the pin head 21.

[0019] The working principle of this application is:

[0020] When in use, the paddle 23 is moved to rotate around the rotating rod 12, thereby driving the sliding piece 22 through the rotating shaft 24 to make the pin head 21 move in the insertion hole 13. During this process, the U-shaped spring 25 squeezes the sliding piece 22 to prevent the sliding piece 22 from being forced to pop out of the connecting seat 1, thereby effectively reducing the movable width and volume of the door and window latch, and avoiding the door and window latch occupying too much width, resulting in the need to increase the door and window width accordingly, resulting in material waste.

[0021] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
