Description
Technical Field
[0001] The utility model relates to the technical field of externally-opening window equipment, and particularly to an externally-opening window screen without a screen window sub-frame. Background Technique
[0002] An externally-opening window is a common window design, characterized in that the window sash opens outwards. This way can not only effectively promote indoor ventilation, but also save indoor space. In summer, opening the externally-opening window allows users to enjoy the coolness of natural wind and improve the living comfort.
[0003] In order to prevent mosquitoes from entering the room while maintaining ventilation, many users choose to install a screen window for the externally-opening window. A screen window is a net-like structure installed on the window. It allows air to circulate while effectively blocking mosquitoes, providing users with a practical and aesthetic solution.
[0004] However, the installation of traditional screen windows often requires adding a sub-frame to the window frame. This step not only increases the complexity of installation, but may also affect the appearance of the externally-opening window. As an auxiliary fixing structure, the sub-frame can provide additional support and limit for the screen window to ensure the stability and durability of the screen window. However, the installation of the sub-frame usually requires additional processes and materials, which not only increases the cost, but may also damage the simple appearance of the window due to the additional frame structure.
[0005] To solve this problem, various innovative screen window designs and installation technologies have emerged on the market. For example, some screen window products adopt a frameless design and are directly installed on the window frame through magnetic or special fixing methods. However, in strong wind weather, due to the lack of the firmness of the sub-frame, the connection between the screen window and the frame is tested, and the screen window with magnetic or other suction methods is easily blown off.
[0006] This not only simplifies the installation process but also maintains the beauty of the window. In addition, some screen windows adopt a detachable design, and users can easily install or remove the screen window according to their own needs. Such a design not only facilitates daily use but also reduces the impact on the appearance of the window.
[0007] In view of the above problems, there is an urgent need to innovate on the basis of the original externally-opening window. Content of the Utility Model
[0008] The technical solution of the utility model provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single, so as to solve the problems raised in the above background technique.
[0009] To achieve the above object, the present utility model provides the following technical solution: An external window screen without a screen window sub-frame, including a window frame, a window sash is installed on the window frame, and a conversion frame is connected to the window frame. A clamping member is connected to the conversion frame, and a screen mesh is installed between the conversion frame and the clamping member through a sealing member. A triggering structure is provided on the conversion frame, and a locking structure is provided between the conversion frame and the window frame.
[0010] Preferably, the triggering structure includes a bracket, a first shaft, a fan disc, a chain, a second shaft, an opening, a full gear, and a toothed plate. A bracket is connected to the conversion frame, and a first shaft is connected between the brackets. A fan disc is installed on the first shaft, and the end of the first shaft penetrates through the bracket and is connected to a chain through a sprocket. The chain is connected to a second shaft through a sprocket, and the second shaft is rotatably connected in the opening, and the opening is opened in the conversion frame. A full gear is connected to the outer wall of the second shaft, and the full gear is meshed with the toothed plate, and the toothed plate is clamped and slidably connected in the conversion frame.
[0011] Preferably, rubber sealing blocks for sealing are distributed in a staggered manner between the side of the conversion frame and the window frame.
[0012] Preferably, the locking structure includes a positive electrode block, a pull rod, a movable rod, a return spring, a fixing plate, and a clamping block. A positive electrode block is provided in the conversion frame, and the positive electrode block is connected to the toothed plate, and a pull rod is connected to the positive electrode block. The end of the pull rod penetrates through the outer wall of the conversion frame away from the window sash. A clamping block is connected to the outer wall of the conversion frame away from the triggering structure. A fixing plate is connected to the window frame, and a movable rod is slidably connected to the end of the fixing plate, and a return spring is connected between the end of the movable rod and the fixing plate.
[0013] Preferably, one side of the positive electrode block close to the clamping block is set as a positive magnetic block, and the positive electrode block is clamped and slidably connected in the conversion frame.
[0014] Preferably, the movable rod is set in a "T" shape, and one end of the movable rod close to the clamping block is set as a negative magnetic block, and the end of the movable rod is clamped and connected to the clamping block.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the outer-opening window screen of the window frame without a screen window, through the arrangement of the conversion frame and the clamping member, the screen mesh can be installed and fixed. Through the arrangement and cooperation of the triggering structure and the locking structure, it is ensured that even under the worst weather conditions, the sealing performance and integrity of the doors and windows can be guaranteed. When a strong wind comes, the wind acts on the fan disc, driving it to rotate together with the first shaft. It is transmitted to the second shaft and the spur gear through the chain. The rotation of the spur gear further drives the rack meshing with it to move precisely. The movement of the rack drives the movement of the movable rod, breaking the influence of the same positive pole repulsion force between the movable rod and the positive pole block. At this time, the return spring plays its role, pushing the movable rod to move on the fixed plate until it contacts and is limited by the conversion frame and the clamping block, avoiding the risk of gaps being generated between the installation of the window screen and the window frame or the window screen falling off due to the wind.

A fan disc 603 is installed on the first shaft 602, and the end of the first shaft 602 passes through the bracket 601 and is connected to a chain 604 through a sprocket. The chain 604 is connected to a second shaft 605 through a sprocket, and the second shaft 605 is rotatably connected in the opening 606, and the opening 606 is opened in the conversion frame 3. A full gear 607 is connected to the outer wall of the second shaft 605, and the full gear 607 is meshed with a toothed plate 608, and the toothed plate 608 is clamped and slidably connected in the conversion frame 3.
[0024] There are rubber sealing blocks for sealing distributed in a staggered manner between the side of the conversion frame 3 and the window frame 1.
[0025] The locking structure 7 includes a positive electrode block 701, a pull rod 702, a movable rod 703, a return spring 704, a fixing plate 705, and a clamping block 706. A positive electrode block 701 is provided in the conversion frame 3, and the positive electrode block 701 is connected to the toothed plate 608, and a pull rod 702 is connected to the positive electrode block 701. The end of the pull rod 702 passes through the outer wall of the conversion frame 3 away from the window sash 2. A clamping block 706 is connected to the outer wall of the conversion frame 3 away from the triggering structure 6. A fixing plate 705 is connected to the window frame 1, and a movable rod 703 is slidably connected to the end of the fixing plate 705, and a return spring 704 is connected between the end of the movable rod 703 and the fixing plate 705.

[0029] When encountering strong wind weather, the wind force acts on the fan disk 603, driving the fan disk 603 to rotate. And according to actual needs, a wind guide plate is sleeved outside the fan disk 603. As the fan disk 603 rotates, it drives the first shaft 602 to rotate. Through the sprocket and chain 604, it drives the second shaft 605 and the full gear 607 to rotate in the opening 606. The full gear 607 drives the meshing-connected tooth plate 608 to move, so that the positive electrode block 701 on the tooth plate 608 is disengaged from the alignment with the movable rod 703. The movable rod 703 moves under the action of the return spring 704. The end of the movable rod 703 contacts and positions the block 706, avoiding the situation that the window screen component is likely to be detached or loosened from the window frame 1 under the action of wind force in strong wind weather. This is the working principle of the external-opening window screen without a window screen sub-frame.
