Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the mounting of the adjustable clips and the grill of the present invention.

In the figure: the window frame comprises a threaded through hole 1, a sliding groove 2, a sliding block end 3, a window frame 4, a rail groove 5, a clamping strip 6, a clamping groove 7, a clamping hook 7-1, a grid 8, a clamping end 8-1 and an adjusting screw 9.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1, a fastener for decorating adjustable tightness of grid, the center of the adjustable fastener is provided with a threaded through hole 1 for installing an adjusting screw, one end of the adjustable fastener is provided with two symmetrical sliding grooves 2 to form a sliding block end 3, the sliding block end 3 is slidably arranged in a longitudinal rail groove 5 on the side of a window frame 4, two clamping strips 6 are symmetrically arranged on two sides of the rail groove 5 on the side of the window frame 4, the clamping strips 6 and the rail groove 5 are integrally formed, the two clamping strips 6 are respectively in sliding clamping connection with the two sliding grooves 2, and one side of the other end of the adjustable fastener, which is close to the window frame 4, is provided with a clamping groove 7 for clamping with a clamping end 8-1 of a grid 8.

Preferably, the threaded through hole 1 is a stepped threaded hole.

Preferably, the stepped threaded hole comprises a circular truncated cone-shaped threaded hole and a cylindrical threaded hole which are integrally formed. In the utility model, the head of the adjusting screw can be accommodated in the circular truncated cone-shaped threaded hole, so that the head of the adjusting screw is prevented from being exposed outside the clamping piece, and the abrasion is generated in the installation process of the grating and the matched installation of the grating and the clamping piece is prevented from being influenced.

Preferably, the clamping groove 7 is of a trapezoidal structure, and a clamping hook 7-1 is formed at the end part of the adjustable clamping piece.

Preferably, the adjustable clip is an elastic clip.

The working principle of the utility model is as follows:

as shown in fig. 2, the sliding block end 3 of the adjustable clamping piece is longitudinally inserted into a longitudinal rail groove 5 on the side of the window frame 4, and the clamping strips 6 on the two sides of the rail groove 5 are respectively installed with the two sliding grooves 2 of the adjustable clamping piece in a matching manner. The adjusting screw passes through the threaded through hole 1 and is installed in a matched mode with the threaded through hole 1 in the window frame 4, and the adjusting screw is used for fixing the adjustable clamping piece at the preset position of the window frame 4. And finally, clamping the clamping end 8-1 of the grating 8 in the clamping groove 7 of the adjustable clamping piece, and matching the clamping end with the clamping hook 7-1 at the end part of the adjustable clamping piece for limiting. When the tightness of grid fastener and grid buckle needs to be adjusted, the adjustment of the tightness of the grid buckle can be realized only by screwing an adjusting screw and adjusting the distance between the grid fastener and the window frame.

According to the utility model, the adjustable installation of the grating can be realized through the adjustment of the adjusting screw 9, and the upper part and the lower part can be adjusted by 1 mm.

In addition, the adjustable clamping piece can be used without an adjusting screw. Because the clamping strip 6 and the sliding groove 2 are mutually matched and installed, the transverse limiting of the adjustable clamping piece is realized, the position of the grid clamping piece can be arbitrarily and manually adjusted in the rail groove 5 only by designing the matching tightness of the sliding block end of the adjustable clamping piece and the rail groove 5 (namely, the friction force between the sliding block end and the rail groove is slightly larger than the dead weight of the adjustable clamping piece, and the free falling body is avoided), and the matching buckle of the grid and the adjustable clamping piece can be realized without using an adjusting screw.

In the dismantlement in-process, grid 8 can have a horizontal pulling force to the grid fastener at the in-process of outwards pulling out, and the grid fastener only passes through the fix with screw on window frame 4 among the prior art for the grid fastener is horizontal atress easily and is dropped, and life shortens, has the potential safety hazard. And in this application, because the cooperation between card strip and the adjustable fastener for adjustable fastener has the card strip to provide the resistance when horizontal atress, avoids being greater than and causes external force to drag to the screw joint department of adjustable fastener, thereby has improved the life of adjustable fastener.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
