DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as a limitation on the utility model.

[0025] A kind of limit device of interior opening and interior tilt window, as shown in Figures 1-4 It includes main body 1 and limiting mechanism 5, limiting mechanism 5 includes first sliding block 501, fourth sliding slot 502 is set in the outer surface of first sliding block 501, second sliding block 503 is clamped and slides in fourth sliding slot 502, fifth sliding slot 504 is set in the two sides of second sliding block 503, spring sleeve rod 505 is arranged in fifth sliding slot 504, connecting block 506 is arranged at one end of spring sleeve rod 505, connecting block 506 is fixedly connected with second sliding block 503, pressing rod 507 is arranged in the top of first sliding block 501 by spring 508, pressing block 509 is arranged in the bottom of pressing rod 507, first inclined surface 510 is set in the two sides of pressing block 509, second inclined surface 511 is arranged in the back of first sliding block 501, pressing rod 507, pressing block 509 and inclined surface form inclined surface transmission mechanism, the moving direction and distance of pressing block can be controlled, spring 508 and spring sleeve rod 505 make limiting mechanism 5 can be deformed when being subjected to external force, and restore original shape after external force disappears.

[0026] Referring to Figure 4There are two second sliders 503, which are symmetrically arranged along the central axis of the first slider 501. The symmetrical arrangement of the two second sliders 503 makes the supporting force on the window more uniform during the sliding process. Since the two second sliders 503 simultaneously bear the weight of the window and the external force during the sliding process, the load-bearing capacity of the entire limiting device is enhanced.

[0027] See Figure 1 , Figure 2 The outer surface of the main body 1 is provided with a first sliding groove 2, which is adapted to the first slider 501. The adaptation of the first sliding groove 2 to the first slider 501 ensures that the window can slide smoothly during opening and closing. Through the guidance and support of the first slider 501 by the first sliding groove 2, the limiting device can maintain the stability of the window.

[0028] See Figure 1 The first slide 2 has a second slide 3 and a third slide 4 on both sides. The second slide 3 is deeper than the third slide 4. Since the second slide 3 and the third slide 4 have different depths, they can cooperate with the second slider 503 to limit the window. The two second slides 3 and the third slide 4 enhance the stability of the limiting device.

[0029] See Figure 1 , Figure 3 The second slide 3 and the third slide 4 are adapted to the second slider 503. When the second slider 503 slides in the second slide 3 or the third slide 4, the opening angle of the window is limited by the depth of the slide, thereby achieving a precise limiting effect. By setting the second slide 3 and the third slide 4 with different depths and shapes, the opening angle of the window can be flexibly adjusted.

[0030] See Figure 1 The top of the main body 1 is provided with an installation groove 6, and a bolt 7 is provided in the installation groove 6. The cooperation between the installation groove 6 and the bolt 7 ensures that the limiting device can be stably installed on the window or window frame and is not easy to loosen or fall off. The limiting device can be easily installed by the cooperation between the bolt 7 and the installation groove 6.

[0031] The utility model discloses an implementation principle is: first, spring 508 pulls down the pressure bar 507 and makes the pressing block 509 through the first slope 510 pressure motion second slope 511, make second sliding block 503 stretch out to both sides, and the connecting block 506 slips in the fifth sliding slot 504 and stretch spring cover pole 505, open the window, first sliding block 501 slip in the first sliding slot 2, and second sliding block 503 slip in the second sliding slot 3, limit the window opening angle, when needing to increase the window opening angle, user pulls down the pressure bar 507, makes the pressing block 509 go up, and spring cover pole 505 makes the connecting block 506 drive second sliding block 503 through the elastic force and go into the fourth sliding slot 502, and open the window to the outside, make first sliding block 501 continue to slip in the first sliding slot 2, and make second sliding block 503 slip into third sliding slot 4, make the window opening angle increase, when the window closes, when second sliding block 503 slip into the second sliding slot 3, spring 508 pulls down the pressure bar 507, makes the equipment reset.
