Description

Technical Field

[0001] The utility model relates to the technical field of door and window equipment, in particular to a plug and a corresponding reel assembly. Background Art

[0002] Screens can effectively prevent mosquitoes from entering from outside, and can filter large dust particles, lint and other foreign matter in the air, providing people with a clean indoor environment. Invisible screens are popular because they can be rolled up, so when not in use, they can prevent dust and damage, and can also ensure the transparency of the window. Invisible screens are screens with mesh that can automatically roll back, mainly for ventilation and mosquito prevention. The frame is tightly attached to the window frame. When it is used, the mesh is pulled down, and when it is not used, the mesh will automatically roll back into the mesh box. It does not take up space, and has strong sealing, which is coordinated with high-end home decoration. At present, when invisible screens are used, most of the scrolls are installed in the mesh box through bearings, which has less sand capacity and poor compatibility. Utility Model Content

[0006] By adopting the above technical solution, two plugs are arranged at both ends of the pull rod, and the end surface area of ​​the storage part of the plug close to one end of the pull rod is larger than the end surface area of ​​the other end of the storage part, so that more space can be reserved at the end of the pull rod to place the pull rope for fixing the gauze, thereby increasing the sand capacity of the gauze, adapting to more occasions, and improving compatibility.

[0007] Furthermore, the end surface area of ​​one end of the storage portion connected to the fixing portion is set to be the same as the end surface area of ​​the pull rod, and the connection is smooth, which facilitates the rolling and unfolding of the gauze.

[0008] Furthermore, the fixing portion is configured as a cylindrical structure, and a plurality of clamping strips are spaced apart on the outer circumference of the fixing portion, and a side of the clamping strip away from the fixing portion is interference-connected with the pull rod, thereby improving the efficiency of installation and disassembly.

[0009] Furthermore, a guiding slope is provided at one end of the clip strip away from the storage portion, so that installation is more convenient.

[0010] Furthermore, the storage portion is configured as a truncated cone structure with a smooth surface, making it more convenient to use.

[0011] Furthermore, the ratio of the end face diameters at both ends of the storage portion is 1 / 3-2 / 3, providing more storage space, thereby increasing the sand holding capacity.

[0012] Furthermore, through mounting holes are provided inside the fixing portion and the storage portion along the central axis direction thereof, and the mounting holes are used for mounting the avoidance, which has a compact structure and saves costs.

[0013] A reel assembly comprises a pull rod for fixing the gauze, two plugs arranged at the ends of the pull rod, and a reset spring arranged inside the pull rod; the plug comprises any of the plugs described above, and the plug is used to reel up the pull rope on the side of the gauze; the reset spring is used to drive the opened gauze to be automatically reeled up.

[0014] In summary, the beneficial effects of the utility model are:

[0015] The utility model provides two plugs at both ends of the pull rod, and the end surface area of ​​the storage part of the plug close to one end of the pull rod is larger than the end surface area of ​​the other end of the storage part, so that more space can be reserved at the end of the pull rod for placing the pull rope for fixing the gauze net, thereby increasing the sand holding capacity of the gauze net, adapting to more occasions, and improving compatibility.
