[0002] The three-link sliding window is a new type of aluminum alloy window structure, which can be extended and retracted freely, especially in the retracted state, the three windows overlap each other, which can greatly increase the window's pass-through area. The existing three-link sliding windows are linked to each other through a pulley structure, that is, a belt is installed on one window, and two groups of connecting parts are installed on the belt, each group of connecting parts is connected to one of the remaining two groups of windows. The above-mentioned three-link sliding window is flexible in sliding and easy to operate, but the linkage structure is relatively complicated. After long-term use, the belts and connecting parts are aged and worn, resulting in linkage failure. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a three-linkage sliding and folding window. The device realizes the three-linkage sliding and folding operation of the window by snapping during the movement of the sliding window. The structure is simple and linkage failure is not easy to occur. At the same time, the device can store and hide the snap-connected sliding seat of the linkage part, so that the user can adjust the window linkage number of the three-linkage sliding and folding window according to needs. It is easy to use and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-linkage sliding and folding window, comprising a sliding window frame;

[0005] Sliding window frame: Sliding frame 1, sliding frame 2 and sliding frame 3 are slidably connected inside it from front to back in sequence. Glass is installed inside the sliding frame 1, sliding frame 2 and sliding frame 3. The upper ends of the front and rear sides of the sliding frame 2 are provided with symmetrically distributed fixed seats. The side of the fixed seat close to the center of the sliding frame 2 is provided with a synchronous seat through an evenly distributed damper. The sliding grooves at the upper left end of the rear side of the sliding frame 1 and the upper right end of the front side of the sliding frame 3 are slidably connected with a snap-in slide, and the snap-in slides are installed in conjunction with adjacent synchronous seats. The device realizes the three-linkage sliding and folding operation of the window through the snap connection during the movement of the sliding window. It has a simple structure and is not prone to linkage failure. At the same time, the device can store and hide the snap-in slide at the linkage position, so that the user can adjust the window linkage number of the three-linkage sliding and folding window according to needs, which is easy to use.

[0006] Furthermore, evenly distributed springs are provided between the fixed seat and the adjacent synchronous seat, and the springs are movably sleeved with the outer ends of the adjacent dampers. Through the compression elastic force of the springs, the moving inertial collision force between the synchronous seat and the card-connecting sliding seat of the three-linkage sliding and folding window is buffered.

[0007] Furthermore, a rubber sheet is provided on one side of the synchronous seat close to the center of the second push-pull frame to prevent the synchronous seat from making hard contact with the card-connecting slide seat during the three-linkage process of the three-linkage sliding and folding window.

[0008] Furthermore, an inner cavity is provided at the upper left end of the sliding frame one and the upper right end of the sliding frame three, and a conical seat is slidably connected to the bottom of the inner cavity. The end of the snap-in slide away from the center of the sliding frame two is installed in cooperation with the adjacent conical seat, and the inclined surface of the conical seat is used to limit the movement of the snap-in slide in the three-linkage sliding and folding window.

[0009] Furthermore, a telescopic column and a second spring are provided between the inner cavity and the adjacent clamping slide seat. The second spring is movably connected to the outer end of the adjacent telescopic column. When the clamping slide seat is not restricted, the clamping slide seat enters the corresponding slide groove through the compression force of the spring.

[0010] Furthermore, the interior of the inner cavity is rotatably connected with a stud via a bearing, the end of the stud close to the center of the sliding window frame is threadedly connected to the adjacent conical seat, and the end of the stud away from the center of the sliding window frame is provided with a control knob to control the movement of the oblique seat in the three-link sliding and folding window.

[0011] Furthermore, rubber sealing strips are provided between the glass and the adjacent sliding frame 1, sliding frame 2 and sliding frame 3 to prevent external dust from entering the gaps between the glass and the sliding frames.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the three-link sliding and folding window has the following advantages:

[0013] 1. When the three-linkage sliding and folding window is pushed, pulled and folded, the window frame 1 moves left and right, and is engaged with the corresponding synchronous seat through the sliding seat, so that the window frame 1 drives the remaining window frames 2 and 3 to be synchronously unfolded or folded. The three-linkage sliding and folding operation of the window is realized by the engagement during the movement of the sliding window. The structure is simple and linkage failure is not prone to occur.

[0014] 2. During the use of the three-linkage sliding and folding window, the user can, according to the use requirements, turn the control knob to connect the threaded connection between the stud and the conical seat, thereby releasing the movement limit of the card-connecting slide, and then the contraction elastic force of the second spring allows the card-connecting slide to enter the corresponding slide groove, thereby releasing the linkage contact between the synchronous seat and the card-connecting slide. The device can store and hide the card-connecting slide at the linkage position, so that the user can adjust the window linkage number of the three-linkage sliding and folding window according to the needs, which is convenient to use.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 , This embodiment provides a technical solution: a three-linkage sliding and folding window, comprising a sliding window frame 1;

[0024] Sliding window frame 1: Sliding frame 1 2, sliding frame 2 3 and sliding frame 3 4 are slidably connected therein from front to back in sequence, and glass 5 is installed inside the sliding frame 1 2, sliding frame 2 3 and sliding frame 3 4. The upper ends of the front and rear sides of the sliding frame 2 3 are provided with symmetrically distributed fixing seats 6, and the side of the fixing seat 6 close to the center of the sliding frame 2 3 is provided with a synchronous seat 9 through a uniformly distributed damper 7. The upper left end of the rear side of the sliding frame 1 2 and the upper right end of the front side of the sliding frame 3 4 are slidably connected with a card-connecting slide 11 in the slide groove, and the card-connecting slide 11 is installed in cooperation with the adjacent synchronous seat 9, and a uniformly distributed spring 1 8 is provided between the fixing seat 6 and the adjacent synchronous seat 9. The springs 1 8 are movably sleeved with the outer ends of the adjacent dampers 7, and a rubber sheet 10 is provided on one side of the synchronous seat 9 close to the center of the sliding frame 2 3. Rubber sealing strips are provided between the glass 5 and the adjacent sliding frame 1 2, the sliding frame 2 3 and the sliding frame 3 4. When the sliding window is pushed and pulled in a three-link manner, the user pulls the sliding frame 1 2 to slide right along the sliding window frame 1. When the sliding frame 1 2 moves to a certain position to the right, the card-connecting slide seat 11 at the upper left end of its rear side contacts the synchronous seat 9 at the upper right end of the front side of the sliding frame 2 3, and the sliding frame 2 3 is driven to move to the right through the card connection between the two. By the same principle, when the synchronous seat 9 at the upper left end of the sliding frame 2 3 contacts the sliding frame When the card-connecting slide 11 at the right front end of the third 4 is card-connected, the sliding frame 2 3 drives the sliding frame 3 4 to move right, thereby realizing the three-link push-pull operation between the sliding frames. When the sliding window is three-linked and folded, through the same principle, when the card-connecting slide 11 on the sliding frame 1 2 contacts the synchronous seat 9 at the upper left end of the front side of the sliding frame 2 3, it drives the sliding frame 2 3 to move left. When the synchronous seat 9 at the upper right end of the rear side of the sliding frame 2 3 contacts the card-connecting slide 11 on the sliding frame 3 4, it drives the sliding frame 3 4 to move left. The device realizes the three-link push-pull folding operation of the sliding window through the contact between the synchronous seat 9 and the card-connecting slide 11. The structure is simple, and the card-connecting slide 11 contacts the synchronous seat 9. When the sliding window is moved, the internal elasticity of the rubber sheet 10 is used to avoid hard contact between the two, thereby realizing deformation protection. At the same time, the elastic contraction of the spring 8 and the elastic elements and bearing elements inside the damper 7 absorb the moving inertial collision force between the synchronous seat 9 and the clamping slide seat 11 through friction or hydraulic resistance and convert it into heat energy release, thereby improving the linkage movement stability between the sliding frames. The rubber sealing strip is used to prevent external dust from entering the gap between the glass 5 and the sliding frame. The device realizes the three-linkage sliding and folding operation of the window through the clamping during the movement of the sliding window. The structure is simple and linkage failure is not easy to occur.

[0025] Among them, the upper left end of the sliding frame 1 2 and the upper right end of the sliding frame 3 4 are both provided with an inner cavity 12, and the bottom of the inner cavity 12 is slidably connected with a conical seat 13, and the end of the card-connecting slide 11 away from the center of the sliding frame 2 3 is installed in cooperation with the adjacent conical seat 13, and a telescopic column 14 and a spring 2 15 are provided between the inner cavity 12 and the adjacent card-connecting slide 11, and the spring 2 15 is movably sleeved with the outer end of the adjacent telescopic column 14, and the inside of the inner cavity 12 is rotatably connected with a stud 16 through a bearing, and the end of the stud 16 close to the center of the sliding window frame 1 is threadedly connected to the adjacent conical seat 13, and the end of the stud 16 away from the center of the sliding window frame 1 is provided with a control knob 17. During the use of the three-linkage sliding and folding window, the user can adjust the position according to the user's preference. When the user needs to move the control knob 17, the control knob 17 drives the corresponding stud 16 to rotate. The stud 16 is threadedly connected to make the conical seat 13 move along the inner cavity 12 toward the end away from the snap-in slide 11, thereby releasing the movement limit of the inclined surface of the conical seat 13 on the snap-in slide 11. Subsequently, the contraction elastic force of the spring 2 15 makes the snap-in slide 11 enter the corresponding slide groove, thereby releasing the linkage contact between the synchronous seat 9 and the snap-in slide 11, so that the user can adjust the linkage number between the windows of the three-linkage sliding and folding window according to the needs. The device can store and hide the snap-in slide 11 at the linkage part, so that the user can adjust the linkage number of the windows of the three-linkage sliding and folding window according to the needs, which is easy to use.

[0026] The working principle of a three-linkage sliding and folding window provided by the utility model is as follows: when the sliding window is three-linked and pushed and pulled, the user pulls the sliding frame 1 2 to make it slide to the right along the sliding window frame 1. When the sliding frame 1 2 moves to the right to a certain position, the card-connecting slide seat 11 at the upper left end of its rear side contacts the synchronous seat 9 at the upper right end of the front side of the sliding frame 2 3. The card connection between the two drives the sliding frame 2 3 to move to the right. By the same principle, when the synchronous seat 9 at the upper left end of the sliding frame 2 3 is card-connected with the card-connecting slide seat 11 at the right front end of the sliding frame 3 4, the sliding frame 2 3 is brought into contact with the card-connecting slide seat 11 at the right front end of the sliding frame 3 4. When the sliding window is three-linked and folded, through the same principle, when the card-connecting slide 11 on the sliding frame 1 2 contacts the synchronous seat 9 at the upper left end of the front side of the sliding frame 2 3, the sliding frame 2 3 is driven to move left. When the synchronous seat 9 at the upper right end of the rear side of the sliding frame 2 3 contacts the card-connecting slide 11 on the sliding frame 3 4, the sliding frame 3 4 is driven to move left. The device realizes the three-linked sliding and folding operation of the sliding window through the contact between the synchronous seat 9 and the card-connecting slide 11. The structure is simple, and the card-connecting slide 11 and the synchronous seat 9 When in contact, the internal elasticity of the rubber sheet 10 is used to avoid hard contact between the two, thereby realizing deformation protection. At the same time, the elastic contraction of the spring 8 and the elastic elements and bearing elements inside the damper 7 absorb the moving inertial collision force between the synchronous seat 9 and the card-connecting slide seat 11 through friction or hydraulic resistance and convert it into heat energy release, thereby improving the linkage movement stability between the push-pull frames. During the use of the three-linkage push-pull folding window, the user can turn the control knob 17 according to the use requirements to drive the corresponding stud 16 to rotate, and the stud 16 Through the threaded connection, the conical seat 13 moves along the inner cavity 12 toward the end away from the card-connecting slide 11, thereby releasing the movement limit of the inclined surface of the conical seat 13 on the card-connecting slide 11, and then the contraction elastic force of the spring 2 15 makes the card-connecting slide 11 enter the corresponding slide groove, thereby releasing the linkage contact between the synchronous seat 9 and the card-connecting slide 11, so that the user can adjust the linkage number between the windows of the three-linkage sliding and folding window according to needs. It is easy to use and prevents external dust from entering the gap between the glass 5 and the sliding frame through the rubber sealing strip.
