[0017] Reference Figures 1-4 A mosquito-proof garden gate frame with an automatic closing device includes a gate frame 1, a base 2 fixedly installed at the bottom of the gate frame 1, a connecting cover 3 fixedly installed at the top of the gate frame 1, a mosquito-proof door 4 provided in the gate frame 1, a connecting block 14 fixedly installed on the top left side of the mosquito-proof door 4, a second bearing 15 fixedly installed on the bottom left side of the mosquito-proof door 4, a rotating rod 6 provided at the top of the gate frame 1 corresponding to the position of the connecting block 14, a first bearing 7 fixedly installed on the outer side of the rotating rod 6, the rotating rod 6 being movably installed on the top of the gate frame 1 through the first bearing 7, a groove being opened at the bottom of the rotating rod 6, the connecting block 14 being able to be inserted into the groove at the bottom of the rotating rod 6, a first sprocket 8 fixedly installed on the rotating rod 6, a chain belt 11 movably installed on the first sprocket 8, a movable rod 9 movably installed in the connecting cover 3, a second sprocket 10 fixedly installed on the movable rod 9, the other end of the chain belt 11 being sleeved on the second sprocket 10, a fixing block 13 fixedly installed on the top right side of the gate frame 1, and a tension spring 12 fixedly installed on the left side of the fixing block 13.

[0018] In this embodiment, a gear 17 is fixedly installed on the bottom side wall of the movable rod 9. A control block 18 is provided on the outside of the gear 17. A connecting groove 19 is provided on the control block 18. The gear 17 can be movably locked in the connecting groove 19. A toothed groove is provided on the left side of the connecting groove 19. The gear 17 meshes with the toothed groove. The first sprocket 8 on the rotating rod 6 will drive the second sprocket 10 through the chain belt 11 to control the movable rod 9 to rotate synchronously. At this time, the gear 17 on the movable rod 9 will mesh with the toothed groove in the connecting groove 19 to drive the control block 18 to move to the left. When the control block 18 moves to the left, it will stretch the tension spring 12.

[0019] In this embodiment, a limiting groove 20 is provided on the top of the gantry 1 corresponding to the position of the control block 18, and a limiting block 21 is fixedly installed on the bottom of the control block 18. The limiting block 21 can be movably installed in the limiting groove 20. The length of the limiting groove 20 is one-quarter of the circumference of the gear 17. The limiting groove 20 and the limiting block 21 cooperate to limit the control block 18, thereby limiting the opening and closing angle of the insect door 4.

[0020] In this embodiment, a fixing ring 22 is fixedly installed on the right end of the control block 18, and the left end of the tension spring 12 can be movably hung on the fixing ring 22. When the insect door 4 is released, the tension spring 12 loses tension and will rebound and contract, and the tension spring 12 will drive the control block 18 to move to the right.

[0021] In this embodiment, a fixing groove 16 is provided on the base 2 at the position corresponding to the second bearing 15. The second bearing 15 can be inserted into the fixing groove 16. The insect door 4 can be quickly and movably installed on the base 2 through the second bearing 15 and the fixing groove 16.

[0022] In this embodiment, a baffle 5 is fixedly installed on the right side of the inner wall of the gantry 1. The baffle 5 installed on the inner wall of the gantry 1 can limit the insect door 4, thus avoiding the insect door 4 from rebounding too much and creating a large gap with the gantry 1, or the insect door 4 from shaking back and forth after resetting.

[0023] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When in use, after the insect door 4 is opened, the connecting block 14 on the insect door 4 will drive the rotating rod 6 to rotate. The first sprocket 8 on the rotating rod 6 will drive the second sprocket 10 through the chain belt 11 to control the moving rod 9 to rotate synchronously. At this time, the gear 17 on the moving rod 9 will mesh with the tooth groove in the connecting groove 19 to drive the control block 18 to move to the left. When the control block 18 moves to the left, it will stretch the tension spring 12. When the insect door 4 is released, the tension spring 12 will lose tension and rebound and contract. The tension spring 12 will drive the control block 18 to move to the right. At this time, the tooth groove in the connecting groove 19 will drive the gear 17 to control the moving rod 9 to reverse. The second sprocket 10 on the moving rod 9 will drive the first sprocket 8 through the chain belt 11 to control the rotating rod 6 to reverse, and reset and close the insect door 4, thereby achieving the effect of automatically closing the insect door 4 and preventing mosquitoes in the garden from flying into the room. The baffle 5 installed on the inner wall of the gantry 1 can limit the insect door 4, preventing the insect door 4 from rebounding too much and creating a large gap with the gantry 1, or the insect door 4 from shaking back and forth after resetting. At the same time, the connecting cover 3 can protect the structure at the top of the gantry 1, preventing parts from being exposed and affecting service life.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
