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] like Figure 1~Figure 3As shown, embodiment 1, a high-sealing hand-cranked switch window structure, includes a frame profile and a fan profile corresponding to the frame profile, a hand-cranked switch structure 13 and a special-shaped thermal insulation strip 8 are installed on the frame profile, a transmission strip 2 corresponding to the hand-cranked switch structure 13 is installed on the fan profile, a special-shaped thermal insulation strip 3 is also installed on the fan profile, a multi-cavity isobaric adhesive strip 4 overlapping with the special-shaped thermal insulation strip 8 is installed on the special-shaped thermal insulation strip 3; a sealing adhesive strip 12 overlapping with the fan profile is installed on the frame profile, and a sealing adhesive strip 11 overlapping with the frame profile is installed on the fan profile. The hand-cranked switch structure 13 is installed on the frame profile and corresponds to the transmission strip 2 installed on the fan profile, ensuring the window opening effect of the hand-cranked switch structure 13. The frame profile and the fan profile are sealed with indoor and outdoor side seals through the sealing strip 11 and the sealing strip 2 12. The multi-cavity isobaric strip 4 installed on the fan profile corresponds to the frame profile to form a third seal. The thermal insulation performance and air tightness between the frame profile and the fan profile are improved, thereby solving the problem of poor window sealing of the hand-cranked switch system.

[0024] In this embodiment, the fan profile includes a small fan structure 1, a large fan structure 5 and an insulation strip 10, and the special-shaped insulation strip 10 is arranged in parallel with the insulation strip 10 and is installed between the small fan structure 1 and the large fan structure 5. The special-shaped insulation strip 13 is provided with at least two installation grooves that cooperate with the multi-cavity isobaric adhesive strip 4, and the special-shaped insulation strip 13 is fish. The length of the large fan structure 5 is A, and A is 65mm-75mm. The length of the small fan structure 1 is B, and B is 10mm-20mm. The transmission bar 2 is a "J"-shaped transmission bar, and the transmission bar 2 is clamped on the small fan structure 1. The transmission bar 2 is used to cooperate with the hand-cranked switch structure 13 as a connecting node of the hand-cranked switch structure 13. The transmission bar 2 is located between the sealing strip 12 and the multi-chamber isobaric adhesive strip to ensure the sealing of the window when the window is closed. The small fan structure 1 is located on the indoor side, the large fan structure 5 is located on the outdoor side, the fan frame is an outward-opening window, and a groove is provided on the small fan structure 1 to overlap with the sealing strip 12, so as to ensure that the transmission bar 2 cooperates with the hand-cranked switch structure 13, so as to avoid the transmission bar 2 affecting the sealing performance of the sealing strip 12 overlapped on the small fan structure.

[0025] In this embodiment, the frame profile includes a small face frame structure 6, a large face frame structure 7 and a heat insulation strip 9, and the special-shaped heat insulation strip 3 is arranged in parallel with the heat insulation strip 9 and is installed between the small face frame structure 6 and the large face frame structure 7. The length of the small face frame structure 6 is C, and C is 24mm-44mm. The length of the large face frame structure 7 is D, and D is 50mm-70mm. The width of the large face frame structure 7 and the hand-cranked switch structure 13 is E, and E is 15mm-25mm. The large face frame structure 7 corresponds to the small face fan structure 1 and the large face frame structure 7 and the small face fan structure 1 are both located on the indoor side. When the fan profile and the frame profile are in a closed state, the indoor side end faces of the large face frame structure 7 and the small face fan structure 1 are located on the same plane, which ensures the neatness and beauty of the matching between the fan profile and the frame profile. The hand-operated switch structure 13 is located between the large face frame structure 7 and the small face fan structure 1. The hand-operated switch structure 13 is installed and supported on the large face frame structure 7, and has good support performance, and can ensure the coordination between the fan profile and the frame profile for opening and closing. The sizes of the small face frame structure 6, the large face frame structure 7, the small face fan structure 1, and the large face fan structure 5 can be adjusted according to the actual installation requirements, and have a wide range of applications.

[0026] This device starts from the replacement of profiles and the design of the structure. Considering that the placement space of the hand-cranked switch will be subject to certain restrictions and interference, the single-sided "C"-shaped insulation strip in the original series of frame and sash structures is replaced with a special-shaped insulation strip with two rubber strip slots on one side. Its main purpose is to fix the isobaric rubber strip on the sash, and the position of the isobaric rubber strip originally on the frame is changed. At the same time, it also forms a good overlap effect with the single-sided "C"-shaped insulation strip on the frame, thereby improving the thermal insulation and sealing performance of the entire system window, achieving the effect of three-property sealing, and also solving the problem of interference between the profiles during the operation of the hand-cranked switch window, avoiding the situation where it cannot be opened and closed. A hardware notch is opened on the profile surface of the sash structure facing away from the rubber strip notch, in order to place the transmission strip on the sash structure to meet the functional design of the hand-crank switch. The transmission strip on the lower horizontal sash is connected to the hand-crank switch connecting rod on the frame, and the roller of the hand-crank switch acts on the transmission strip on the sash to realize the function of opening and closing the window. The hand-crank switch on the vertical side frame is connected to the transmission strip with a locking point and perfectly connects with the lock block on the sash during the closing process to complete the locking function. The transmission strip on the vertical sash plays a role in raising the lock block. Therefore, in order to solve the above background problems, this hand-crank lever switch window structure with high sealing performance is designed.

[0027] Embodiment 2, a highly sealed hand-operated switch system window structure, such as Figure 1 As shown in the figure, 1 is a small face fan structure, 2 is a "J"-shaped transmission strip, 3 is a special-shaped insulation strip with two rubber strip slots on one side, 4 is a multi-cavity isobaric rubber strip, 5 is a large face fan structure, 6 is a small face frame structure, 7 is a large face frame structure, and a is a hand-cranked switch structure. Figure 3 In the fan structure, A is the end of the large fan surface, B is the end of the small fan surface, in the frame structure, C is the end of the small frame surface, and D is the end of the large frame surface.

[0028] The side vertical sash frame a structure is connected to a transmission bar equipped with a locking point, which is on the same vertical plane as the vertical hand-cranked switch. The 2 transmission bar structures on the sash can raise the locking block on the sash, and the locking function of the sash frame is realized through the action of the hand-cranked switch. The lower horizontal sash frame a structure is equipped with a sliding support on the middle frame, which is on the same horizontal plane as the horizontal hand-cranked switch. The roller on the connecting rod of the hand-cranked switch is perfectly connected to the transmission bar on the sash. The linkage between them and the action of the sliding support can realize the switching function of the entire system window.

[0029] Figure 2 In the middle, b is the overlap structure of the sash frame, c1 and c2 are the overlap structures of the sash frame rubber strips, and c3 is the overlap structure of the isobaric rubber strips and the insulation strips. The b structure transfers the isobaric rubber strips on the traditional frame to the sash. The design of the b structure completely avoids interference with other profiles during the operation of the hand-cranked switch, so that the entire process of opening and closing the window is smooth. The "c"-shaped insulation strip is replaced with a special-shaped insulation strip with two rubber strip notches on one side, which can not only fix the isobaric rubber strips on the sash, but also be in seamless contact with the isobaric rubber strips when the window is closed, so that the window can still maintain a three-property seal when closed, improving the airtightness and thermal insulation performance of the entire window.

[0030] Figure 3 A is the large side of the sash, B is the small side of the sash, C is the small side of the frame, and D is the large side of the frame. The size range of A is 65mm-75mm, the size range of B is 10mm-20mm, the size range of C is 24mm-44mm, and the size range of D is 50mm-70mm. Ensure the integrity of adaptation, form a more complete system window system, and provide more high-quality solutions for different environments, different situations, and different choices. E is the profile surface on the inner side of the large side of the frame, and the size range of E is 15mm-25mm. Its main function is to support and bear the weight of the rocker switch structure c.

[0031] The material of the isobaric strip is EPDM, which has excellent mechanical properties, chemical resistance and heat resistance, and also shows strong weather resistance. The material of the thermal insulation strip is PA66 (nylon), which has high rigidity, good heat resistance, excellent corrosion resistance, and good electrical properties. Both material properties can meet the strict requirements of ultra-low energy consumption windows.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
