[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, according to Figures 1-7 As shown, a tightly sealed door and window includes a window frame 1, a sliding door 2 that is slidably connected to the inside of the window frame 1, a handle 3 that is fixedly connected to the outer wall of the sliding door 2, adhesive strips 4 that are glued to the inner side of the sliding door 2, a locking component 5 that is provided inside the sliding door 2, and a fixing component 6 that is provided between the sliding doors 2.

[0028] The locking assembly 5 includes a plastic strip 501 disposed on the outer wall of the sliding door 2. A sealing strip 502 is fixedly connected to the outer wall of the plastic strip 501. Two sets of inserts 503 are fixedly connected to the inner wall of the plastic strip 501. The outer walls of the two sets of inserts 503 are movably inserted into the interior of the sliding door 2. A slot 504 is opened at the top of each set of inserts 503. A channel 505 is symmetrically opened inside the sliding door 2. A locking block 506 is engaged inside each set of slots 504. A fixing strip 507 is fixedly connected to the outer wall of each set of locking blocks 506. The fixing strip 507 and the outer wall of the locking block 506 are slidably connected inside the channel 505. The bottom of each set of fixing strips 507 is... A driven wedge 508 is welded on. The inner walls of the two driven wedges 508 are provided with sliding grooves 509. An active wedge 510 is slidably connected between the inner walls of the two driven wedges 508. A sliding groove 512 is provided on the inner wall of the sliding door 2. A button 513 is slidably connected inside the sliding groove 512. One end of the button 513 penetrates the sliding door 2 and is fixedly connected to the active wedge 510. A first spring 514 is sleeved on the outer wall of the button 513. The sliding groove 512 has a structure that is wide in the middle and narrow at the end. The first spring 514 is located in the middle of the sliding groove 512. A slider is symmetrically fixedly connected to the outer wall of the active wedge 510. The size of the slider is adapted to the two sliding grooves 509.

[0029] The overall effect of Embodiment 1 is as follows: Through the design of the locking component 5, a double seal and stable locking of the sliding door 2 are achieved. The sealing strip 502 and the rubber strip 4 work together to effectively fill the gaps between the sliding door 2 and the window frame 1, and between the sliding doors 2 themselves, forming a tight sealing structure. This greatly improves the sealing performance of the doors and windows, effectively blocking the intrusion of wind, rain and dust, while reducing the transmission of external noise into the room and enhancing the sound insulation effect. When the button 513 is pressed and then released, the active wedge 510 pushes the driven wedge 508 to move, so that the locking block 506 is engaged in the slot 504 of the insert block 503, and the plastic strip 501 is firmly fixed on the sliding door 2. This ensures that the sealing strip 502 and the rubber strip 4 are always tightly fitted to the gaps in the doors and windows. Even if subjected to external impact, it is not easy to loosen or shift, ensuring the durability of the sealing effect.

[0030] Example 2, according to Figures 6-7 As shown, the fixing component 6 includes a pin 601 slidably connected inside the two sliding doors 2. Two protrusions 602 are fixedly connected to the outer wall of the pin 601. A second spring 603 is sleeved on the outer wall of the pin 601. The outer wall of the pin 601 penetrates the inner wall of one of the sliding doors 2 and is fixedly connected to a knob 604. An installation groove 605 is opened on the inner wall of the other sliding door 2. The pin 601 is slidably connected inside the installation groove 605. A connecting groove 606 is opened on the inner wall of the other two sliding doors 2. The pin 601 and the external protrusions 602 are engaged with the connecting groove 606. The installation groove 605 has a structure that is wider in the middle and narrower at both sides. The second spring 603 is installed in the middle position inside the installation groove 605. The connecting groove 606 has a cross groove structure. The protrusions 602 are rotatably connected inside the cross groove.

[0031] The overall effect of Embodiment 2 is as follows: It mainly achieves reliable fixation and convenient adjustment between the sliding doors 2. By rotating the knob 604, the insert 601 is driven to move within the mounting groove 605 and the connecting groove 606. When the insert 601 and its protrusion 602 are engaged in the connecting groove 606, the two sliding doors 2 can be firmly connected together, effectively limiting the relative sliding of the sliding doors 2, making the overall structure of the door and window more stable, enhancing the anti-theft performance and wind pressure resistance of the door and window. In bad weather or under external force, the sliding doors 2 will not easily shake or shift. The setting of the second spring 603 ensures that the insert 601 always maintains a certain preload when the knob 604 is not rotated, ensuring the engagement stability of the insert 601 and the connecting groove 606. When it is necessary to move the sliding door 2, simply rotate the knob 604 to disengage the insert 601 from the connecting groove 606, and the sliding door 2 can be easily pushed. The operation is simple and flexible.

[0032] The working principle of the entire device is as follows: When it is necessary to close the door and window, push the sliding door 2 to slide inside the window frame 1, so that the two sliding doors 2 gradually approach each other. At this time, the rubber strip 4 on the inner side of the sliding door 2 first contacts and initially seals the gap between the door / window and the window frame 1, reducing the air flow during the initial closing. After the two sliding doors 2 are completely closed, press the button 513 set in the sliding groove 512 on the inner wall of the sliding door 2. Since the sliding groove 512 has a structure that is wide in the middle and narrow at both ends, it can reserve a position for the first spring 514. The button 513 drives the active wedge 510 to slide inside the sliding door 2, compressing the first spring 514 sleeved on the outer wall of the button 513. The slider on the outer wall of the active wedge 510 and the sliding groove 509 on the inner wall of the driven wedge 508 are connected. When the active wedge 510 moves, the slider slides within the groove 509, pushing the driven wedge 508 upward within the channel 505. As the driven wedge 508 moves upward, it causes the fixing strip 507 and the locking block 506 on the fixing strip 507 to move synchronously. The locking block 506 extends out of the channel 505. At this time, the button 513 is released, the first spring 514 returns to its original position, and the locking block 506 engages with the slot 504 at the top of the insert 503. The insert 503 is fixed to the inner wall of the plastic strip 501. Simultaneously, the sealing strip 502 on the plastic strip 501 is compressed, tightly adhering to the outer wall of the other sliding door 2, filling the gap between the two sliding doors 2 and achieving a seal. At the same time, the two sets of inserts 503 are engaged by the locking block 506. Next, the plastic strip 501 is fixed to the outer wall of the sliding door 2, so that the two sliding doors 2 are securely locked after closing, preventing the seal from failing due to loosening. After the locking component 5 is locked, the knob 604 at one end of the insert 601 is rotated. The outer wall of the insert 601 is fitted with a second spring 603. The mounting groove 605 has a structure that is wider in the middle and narrower at both sides. The second spring 603 is located in the middle of the mounting groove 605. Rotating the knob 604 causes the insert 601 to slide in the mounting groove 605. The protrusion 602 on the outer wall of the insert 601 moves accordingly. When the insert 601 slides to a certain position, the protrusion 602 enters the connecting groove 606 on the inner wall of the other sliding door 2. Since the connecting groove 606 has a cross groove structure, the protrusion 602 can move in the cross groove. Rotate the knob 604 inwards at a certain angle to lock the protrusion 602 in the cross groove, and engage the insert 601 with the connecting groove 606. This further enhances the stability of the two sliding doors 2 after they are closed, ensuring the sealing effect of the locking component 5 remains effective, while not affecting the normal opening and closing operation of the doors and windows. When opening the doors and windows, first rotate the knob 604 in the opposite direction to make the protrusion 602 rotate in the cross groove and disengage from the locked state. The insert 601 retracts into the mounting groove 605 under the action of the second spring 603, and the fixing component 6 is released from fixation. If the sealing strip 502 needs to be replaced, simply press the button 513 to disengage the locking block 506 from the locking groove 504, and then remove and replace the entire sealing strip 502 and the plastic strip 501 connected to it.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
