The second side wall is provided with a secondary guide groove extending along the length direction of the installation body. The tail of the secondary guide groove is downward Bending in a 90° arc, the secondary block is provided with two limit protrusions that slide along the secondary guide groove; in the direction of the buffer stroke, the starting point of the stroke of the secondary guide groove is located at the starting point and end point of the primary guide groove Between, the stroke end point of the secondary guide groove is located behind the stroke end point of the primary guide groove.

As a further improvement, the above-mentioned primary buffer and the above-mentioned secondary buffer preferably adopt the following two solutions: first, both use telescopic springs as buffers. Its two, all adopt the combined structure of gas spring and back-moving spring as buffer.

As a further improvement, the above-mentioned secondary buffer is hinged with a connecting block, the connecting block is hinged with a connecting rod, and the connecting rod is hinged with the above-mentioned secondary clamping block, and the installation positions of the above-mentioned primary buffer and secondary buffer are the same in the direction of the buffer stroke .

As a further improvement, the strokes of the above-mentioned primary guide groove and secondary guide groove are respectively 5-25 cm.

From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: the buffer device of the utility model has a secondary buffer function, can withstand a relatively large thrust, and is suitable for heavy-duty aluminum alloy doors and windows. The stroke can reach 40cm, which greatly improves the safety and service life of heavy aluminum alloy doors and windows, and the buffer device can be embedded in the track of the profile without affecting the appearance of aluminum alloy doors and windows.

detailed description

The specific embodiment of the utility model is described below with reference to accompanying drawing.

With reference to Fig. 1, Fig. 2, Fig. 3, the buffer device for heavy-duty sliding doors and windows, it comprises installation body 1 and the primary buffer 21 that is assembled on the first side wall of installation body 1, primary block 22 and primary Housing 23, the first side wall is provided with a first-level guide groove 20 extending along the length direction of the installation body 1, the tail of the first-level guide groove 20 is bent downward in a 90° arc, and the first-level clamping block 22 is provided with Two limiting protrusions sliding along the primary guide groove 20 . It also includes a secondary buffer 31, a secondary clamp block 32, and a secondary housing 33 assembled on the second side wall of the installation body 1 above. The second side wall is provided with a secondary buffer extending along the length of the installation body 1. The guide groove 30, the tail of the secondary guide groove 30 is bent downward in a 90° arc, and the secondary clamp block 32 is provided with two position-limiting projections that slide along the secondary guide groove 30; the secondary buffer 31 is hinged with The connecting block 34 is hinged with a connecting rod 35 , and the connecting rod 35 is hinged with the above-mentioned secondary clamping block 32 . Preferably, the primary buffer 21 and the secondary buffer 31 use the same type of buffer, and the installation positions of the primary buffer 21 and the secondary buffer 31 are the same in the direction of the buffer stroke. Both the primary buffer 21 and the secondary buffer 31 are combined structures of gas springs and return springs. In the buffer stroke direction, the stroke starting point of the secondary guide groove 30 is located between the starting point and the end point of the primary guide groove 20 , and the stroke end point of the secondary guide groove 30 is located behind the stroke end point of the primary guide groove 20 . The strokes of the first-level guide groove 20 and the second-level guide groove 30 are respectively 5 to 25 cm. The buffer of the utility model can be assembled in the profiles of doors and windows, and can also be assembled in the guide rail profiles for sliding doors and windows, and then the corresponding guide rail profiles or The door and window profile is fixedly equipped with a clamping rod 4 that matches the bayonet sockets of the primary clamping block 22 and the secondary clamping block 32 . During use, with reference to Fig. 1, Fig. 2, Fig. 3, two latch bars 4 corresponding to the primary block 22 and the secondary block 32 are fixedly mounted on the door and window, and the buffer of the present embodiment is assembled in the guide rail profile. When the locking rod 4 of the door and window slides to the first-level locking block 22, the outer end of the locking bar 4 snaps into the bayonet of the first-level locking block 22 and drives the first-level locking block 22 to slide along the first-level guide groove 20, passing through the first-level buffer The buffer of the device 21 decelerates the doors and windows. When another clamping rod 4 is connected with the secondary clamping block 32, the clamping rod 4 drives the secondary clamping block 32 to slide, and the buffering of the secondary buffer 31 further decelerates the doors and windows. The clamping block 22 and the secondary clamping block 32 can slide synchronously or separately, depending on the positional relationship between the primary guide groove 20 and the secondary guide groove 30, the clamping blocks (the primary clamping block 22 and the secondary clamping block 32) When sliding to the tail bending part of the guide groove (the first-level guide groove 20 and the second-level guide groove 30), under the action of the limit protrusion of the clamp block and the guide groove, the clamp block will rotate, so that the clamp block is fixed on the The tail of the guide groove is unlocked, and the block is reset under the action of the return spring. The buffer device of the utility model has a secondary buffer function and can withstand relatively large thrust. It is suitable for heavy aluminum alloy doors and windows with a weight of 50kg to 150kg. The buffer stroke can reach 40cm, which greatly improves the safety and usability of heavy aluminum alloy doors and windows. Life, and the buffer device can be embedded in the track of the profile, without affecting the appearance of aluminum alloy doors and windows.

The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, and any non-substantial modification of the utility model by using this concept should be an act of violating the protection scope of the utility model.
