Description

Technical Field

[0001] This utility model relates to the field of door and window component technology, and in particular to a shielding mechanism for door and window components. Background Technology

[0002] Door and window components are an important part of the building envelope. They not only affect the building's aesthetic appearance, but also play a key role in heat insulation, sound insulation, waterproofing, and security. In summer, due to the sun's rays, sunlight can easily penetrate the interior through door and window components, causing the indoor temperature to rise. It can also cause indoor furniture to age prematurely due to prolonged exposure to sunlight, reducing the furniture's lifespan. Therefore, to prevent sunlight from entering the interior, a sunshade curtain is usually installed on one side of the door and window components.

[0003] However, traditional blinds still have some problems in use. Traditional blinds require manual opening and closing, which is quite troublesome in actual life. Therefore, a blinding mechanism for door and window components is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a shielding mechanism for door and window components, so as to solve the defect that the shielding curtains of existing door and window components still need to be manually opened and closed during use, which is quite troublesome in actual use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shielding mechanism for a door and window assembly, including a door and window assembly and a connecting frame; a shielding structure is provided at the top front of the door and window assembly; the shielding structure includes a mounting box, the mounting box is fixed to the top front of the door and window assembly, a bidirectional threaded rod is installed inside the mounting box, a threaded sleeve is installed on the outside of the bidirectional threaded rod, a shielding curtain is installed at the bottom end of the threaded sleeve, the other end of the shielding curtain is connected to the bottom end of the mounting box, and a motor is installed at one end of the mounting box.

[0006] Preferably, the outer side of the bidirectional threaded rod is provided with an external thread, and the inner side of the threaded sleeve is provided with an internal thread, forming a threaded connection between the bidirectional threaded rod and the threaded sleeve.

[0007] Preferably, the blind curtain is provided in two sets, and the two sets of blind curtain are symmetrically distributed at the front end of the door and window assembly.

[0008] Preferably, a connecting frame is installed on one side of the bottom end of the screw sleeve, and a wiping structure is provided on one side of the connecting frame. The wiping structure includes a slot, which is opened inside both ends of one side of the connecting frame. A locking block is installed inside the slot, and a wiping cotton is fixed on one side of the locking block.

[0009] Preferably, the card block has a fixing hole inside, and a fixing bolt is installed inside the fixing hole, with the fixing bolt and the fixing hole forming a threaded connection.

[0010] Preferably, one side of the card block is inserted into the interior of the card slot, and the card block and the card slot form an engaging structure.

[0011] Preferably, there are two sets of fixing bolts, and the two sets of fixing bolts are symmetrically distributed at both ends on one side of the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up a shielding structure, when sun shading is needed, the two sets of screw sleeves can be moved to the middle position through the cooperation of the two-way threaded rod and screw sleeve, thereby unfolding the two sets of shielding curtains and blocking the mirror surface of the door and window components to prevent the sun from shining into the room. This makes it more convenient to open and close the shielding curtains, thus completing the sun shading work.

[0014] With its wiping structure, the wiping cotton can be quickly installed when using door and window components through the cooperation of the clips and slots, making the installation of the wiping cotton more convenient. In addition, whenever the curtain is opened or closed, the connecting frame will drive the wiping cotton to wipe the mirror surface of the door and window components, reducing dust on the mirror surface and making it more convenient for manual cleaning of the mirror surface later.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a shielding mechanism for door and window components, such as... Figures 1-5 As shown, it includes a door and window assembly 1 and a connecting frame 4; a shielding structure 2 is provided at the top front of the door and window assembly 1;

[0023] A connecting frame 4 is installed on one side of the bottom end of the threaded sleeve 205. A wiping structure 3 is provided on one side of the connecting frame 4. The wiping structure 3 includes a slot 303. The slot 303 is opened inside both ends of one side of the connecting frame 4. A locking block 301 is installed inside the slot 303. A wiping cotton 302 is fixed on one side of the locking block 301. A fixing hole 305 is opened inside the locking block 301. A fixing bolt 304 is installed inside the fixing hole 305. The fixing bolt 304 and the fixing hole 305 form a threaded connection. One side of the locking block 301 is inserted into the slot 303. The locking block 301 and the slot 303 form a locking structure. Two sets of fixing bolts 304 are provided. The two sets of fixing bolts 304 are symmetrically distributed at both ends of one side of the connecting frame 4.

[0024] In a further preferred embodiment of this utility model, such as Figures 4-5 As shown: When using the door and window assembly 1, insert the clip 301 on one side of the wiping cotton 302 into the slot 303 to complete the installation of the wiping cotton 302. After the wiping cotton 302 is installed, insert one end of the fixing bolt 304 through the connecting bracket 4 into the fixing hole 305 and rotate it to complete the installation of the wiping cotton 302. This allows the connecting bracket 4 to drive the wiping cotton 302 to wipe the mirror surface of the door and window assembly 1 every time the curtain 201 is opened and closed, reducing dust on the mirror surface and making it more convenient for manual cleaning of the mirror surface in the future, thus completing the wiping work.
