[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] As shown in Figures 1 to 3 A glue strip-free buffer includes a fixed block 1, the symmetrical side of the fixed block is respectively provided with an inclined recess 2, the bottom end depth of the inclined recess is greater than the top end depth of the inclined recess; in the embodiment, the fixed block is a conventional structure of the prior art, so it is not described in detail;

[0030] And in the embodiment, the inclined recess is respectively provided with a buffer 3, the edge of the buffer extends out of the surface of the fixed block when it is at the deepest part of the inclined recess. When the sash is lifted, the buffer falls to the bottom end of the inclined recess under the action of its own gravity. Since the inclined recess is inclined, when the buffer is at the bottom end of the inclined recess, the height of the buffer extending out of the surface of the fixed block is small, so the resistance between the buffer and the door and window frame is the lowest. When descending, due to the resistance of friction, the buffer will gradually move to the upper end of the inclined recess, so the height of the buffer extending out of the surface of the fixed block will gradually increase, thereby the frictional resistance between the buffer and the door and window frame will also gradually increase, thereby the descending speed is reduced, preventing the hand from being pinched or colliding with the bottom edge of the door and window frame, improving the use safety and reliability. It not only reduces the use of glue strips, but also reduces the friction noise, and is not easy to be stuck or slip.

[0031] In the embodiment, a C-shaped limiting groove 4 is arranged on the symmetrical inner wall of the top end of the inclined groove, and a sliding block 5 is arranged on the upper part of the inclined groove, and an adjusting screw 6 is arranged on the sliding block, the symmetrical edges of the sliding block are inserted into the C-shaped limiting groove, and the adjusting screw is screwed on the sliding block to limit the height of the buffer in the inclined groove. By adjusting the length of the adjusting screw extending into the inclined groove, the height of the buffer in the inclined groove is limited, thereby meeting the use requirements in different situations.

[0032] In other embodiments, the adjusting screw 6 can be directly arranged at the top end of one of the inclined grooves to adjust the sliding height of one of the buffers. In fact, the adjusting screw can also be arranged as two, and the two adjusting screws are respectively arranged at the top ends of the two inclined grooves to adjust the sliding heights of the two buffers.

[0033] Of course, when the top wall and the side wall of the fixing block 1 are designed in an integrated manner, that is, the sliding block 5 is no longer arranged separately, the adjusting screw 6 can also be directly arranged on the top wall and adjust the sliding height of the buffer.

[0034] In the embodiment, the buffer is two rollers, and the two rollers are respectively arranged in the two inclined grooves, the sliding block is a right-angled trapezoid, and the outer side is a right-angled edge. Moreover, in order to facilitate installation and use, an installation block 7 is integrally formed on the outer surface of the fixing block, and the installation block and the inclined grooves are arranged on different sides of the fixing block. The installation block is mainly used for installation in the corresponding position.

[0035] In actual application, the two buffers are of the same size. The two buffers can also be of different sizes.

[0036] The utility model has the positive effect: the utility model discloses the structure is reasonably arranged, and it respectively sets up inclined groove on the symmetrical side of fixing block, and respectively sets up buffer in inclined groove, and it does not need to set up again rubber strip, can reduce the use of rubber strip when using, and adopts buffer cooperation inclined groove, also can reduce the noise, simultaneously also will not appear the situation of skidding and jamming, has improved the use smoothness, and also set up two buffers, also is favorable to improving the effectiveness and reliability of buffering, can prevent the situation of hand clamping or collision, uses stably reliable, and the applicability is strong.
