Description

Technical Field

[0001] This utility model belongs to the field of door curtain installation technology, specifically relating to a metal mosquito-proof door curtain. Background Technology

[0002] The main function of mosquito-proof door curtains is to reduce the entry of mosquitoes into the room through physical barriers, thereby reducing the risk of disease transmission and improving the hygiene of the living environment. In particular, they can reduce skin problems caused by mosquito bites, especially for the elderly, children and people with allergies. Mosquito-proof door curtains made of diamond mesh form an effective barrier by blocking mosquitoes through fine mesh.

[0003] For example, in the Chinese utility model patent application CN214484173U, entitled "A New Type of Easy-to-Install Mosquito and Insect Proof Door Curtain," although the curtain can be flexibly installed on door frames of any size using a screw rod, sliding sleeve, connecting rod, positioning plate, spring, and moving plate, making it widely applicable, the spring fixing requires precise calibration of the position and has limited stability. Utility Model Content

[0004] The purpose of this utility model is to provide a metal mosquito-proof door curtain with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A metal mosquito-proof door curtain includes a support rod, both ends of which are provided with telescopic fixing structures. A first slot is fixedly connected to the lower side of the support rod, and a detachable first door curtain and a second door curtain are provided below the first slot.

[0007] As a further optimization of this utility model, the telescopic fixing structure includes a threaded sleeve rotatably connected to the top of the support rod, a threaded rod threadedly connected inside the threaded sleeve, a fixing block fixedly connected to the top of the threaded rod, and a guide rod slidably connected to the inside of the fixing block.

[0008] As a further optimization of this utility model, a rubber pad is fixedly connected to the outside of the fixing block, and the first and second door curtains are both made of 304 stainless steel.

[0009] As a further optimization of this utility model, the top ends of the first door curtain and the second door curtain are both fixedly connected to a second slot, and a first magnetic strip is installed inside the first slot and the second slot, and the first slot and the second slot are fixed by the first magnetic strip.

[0010] As a further optimization of this utility model, a second magnetic strip is fixedly connected to one side of both the first and second door curtains, and the first magnetic strip is installed inside the second magnetic strip.

[0011] As a further optimization of this utility model, a sleeve magnetic adsorption is fixedly sleeved on the outer side of the support rod magnetic adsorption, and the bottom of the sleeve magnetic adsorption is magnetically adsorbed and fixedly connected to the first slot.

[0012] The beneficial effects of this utility model are as follows: This utility model changes the position of the fixing block and the rubber pad by the cooperation of the threaded sleeve and the threaded rod. By changing the overall length of the support rod, it can be installed on door frames of different sizes. Then, the first magnetic strip inside the first slot and the second slot can be used to fix the position of the first door curtain and the second door curtain, and it is also convenient to disassemble and replace the first door curtain and the second door curtain.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] like Figure 1 , Figure 2As shown, a metal mosquito-proof door curtain includes a support rod 1. A sleeve 2 is fixedly fitted onto the outside of the support rod 1. The bottom of the sleeve 2 is fixedly connected to a first slot 3. The first slot 3 is sewn to the bottom of the sleeve 2, facilitating subsequent replacement of the first slot 3. A first curtain 5 and a second curtain 6 are both fixedly connected to their top ends with second slots 4. The first curtain 5 and the second curtain 6 are made of metal, such as a 304 stainless steel wire mesh, which has high tensile strength, corrosion resistance, and is not prone to rust. The second slots 4 are sewn to the top ends of the first curtain 5 and the second curtain 6, facilitating subsequent fixation of the first curtain 5 and the second curtain 6, and also facilitating subsequent disassembly and replacement of the second slots 4. A first magnetic strip 9 is installed inside both the first slot 3 and the second slot 4. The first slot 3 and the second slot 4 are fixed together by the first magnetic strip 9. The first magnetic strip 9 in slot 3 and the first magnetic strip 9 in slot 4 magnetically attract and fix the second slot 4, the first curtain 5 and the second curtain 6, which also facilitates the subsequent disassembly and replacement of the first curtain 5 and the second curtain 6, and facilitates the cleaning of the first curtain 5 and the second curtain 6. The first magnetic strip 7 is fixedly connected to one side of the first curtain 5 and the second curtain 6. The outer side of the second magnetic strip 7 is wrapped with a cloth cover, which facilitates the subsequent sewing of the side of the first curtain 5 and the second curtain 6. The first magnetic strip 9 is fixed by the second magnetic strip 7, which also facilitates the subsequent replacement of the first magnetic strip 9. The first magnetic strip 5 and the second curtain 6 are closed by the magnetic attraction of the first magnetic strip 9 inside the two second magnetic strips 7. The other side of the first curtain 5 and the second curtain 6 is covered with adhesive, which makes it easy to stick the first curtain 5 and the second curtain 6 to the door frame (not shown in the figure), which facilitates the overall installation and the subsequent disassembly.

[0020] like Figure 2 and Figure 3 As shown, the telescopic fixing structure 8 includes a threaded sleeve 801 rotatably connected to the top of the support rod 1. A threaded rod 802 is threadedly connected inside the threaded sleeve 801, and a rubber sleeve is fixedly connected to the outside of the threaded sleeve 801 to facilitate subsequent rotation of the threaded sleeve 801. Rotating the threaded sleeve 801 changes the distance between the threaded rod 802 and the door frame, facilitating fixing to door frames of different sizes. A fixing block 803 is fixedly connected to the top of the threaded rod 802, and a guide rod 805 is fixedly connected to the inside of the fixing block 803. The guide rod 805 is slidably connected to the inside of the support rod 1. A rubber pad 804 is fixedly connected to the outside of the fixing block 803. Changing the position of the threaded rod 802 moves the fixing block 803, which then abuts against the door frame to fix the entire structure. The rubber pad 804 increases the friction between the fixing block 803 and the door frame, preventing the fixing block 803 from slipping. When the threaded rod 802 moves, the guide rod 805 guides the fixing block 803, preventing it from shifting position during rotation.

[0021] It should be noted that, in use, the user adjusts the distance between the threaded rod 802 and the fixing block 803 and the door frame (not shown in the figure) by rotating the threaded sleeve 801. After adjusting to a suitable distance, stop rotating the threaded sleeve 801. Then, install the first magnetic strip 9 inside the first slot 3 and the second slot 4. The first magnetic strip 9 inside the first slot 3 and the second slot 4 cooperates to fix the position of the first curtain 5 and the second curtain 6. One side of the first curtain 5 and the second curtain 6 is attached to the door frame with adhesive. Then, the first magnetic strip 9 is installed inside the second magnetic strip 7. The second magnetic strip 7 makes the first curtain 5 and the second curtain 6 stick together, preventing mosquitoes from entering through the gaps.

[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
