Description

The sister block of slide door or window

Technical field

The utility model relates to a kind of carriage of slide door or window, particularly a kind of sister block of slide door or window.

Background technology

The present slide door or window sister block that uses, mainly be by shell, inner casing, wheel assembly, support, bearing pin and adjustment screw are formed, though overcome single-sheaved block unbalance stress, the easy beat shortcoming that gets loose, but have complex structure, and easily overstep the limit, regulate the shortcoming apart from complex operation step of door leaf and following rail.

Summary of the invention

The utility model has overcome the shortcoming of prior art, provides a kind of simple and reasonable, can regulate the distance of door leaf and following rail easily, the sister block of the sliding door that effectively anti-limited slip wheel is overstepped the limit.

To achieve these goals, the utility model is to realize by following technical scheme:

The sister block of slide door or window comprises wheel assembly, and support connects the U type frame of two wheel assemblies, roller pin, and axle pin, adjustment screw also is provided with spring and nutplate especially; Described support is the member in band chamber, and its upper right corner has extension, and the top of extension has pin-and-hole, and lower left quarter has waist through hole, and the side has elongated hole, the axes intersect in two holes, and the upper left corner is provided with groove, and the groove bottom is porose; Nutplate places in the waist through hole of support; Spring is a flat spring, and the one end turns back into bending part, and the termination outwards turns up and form projection, is installed in the hole of groove bottom of support.

U type frame lower, transverse is symmetrically arranged with two pin-and-holes, is provided with a pin-and-hole on longitudinal centre line top; Pin-and-hole on roller pin is passed on the pin-and-hole of support extension and the U type frame vertically is rotationally connected support and U type frame; The elongated hole that adjustment screw is passed support cooperates with nutplate.

Advantage of the present utility model is:

1, simple and reasonable, compare with sister block structure in the past, deducted inner casing, simplify the structure, but reached same effect of regulating two pulley balances automatically.

2, it is simple to regulate operating procedure, can adjust the distance of door leaf and lower frame by the change of adjustment screw position, simple to operate.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As shown in Figure 1 and Figure 4, for the sister block of slide door or window is installed in user mode figure on the door leaf, comprise wheel assembly 4, support 3 connects the U type frame 5 of two wheel assemblies, adjustment screw 1, and roller pin, axle pin also is provided with spring 6 and nutplate 2 especially; By adjustment screw 1 the sister block structure is buckled in the lower frame of door, Yishanmen is installed two sister block structures simultaneously.

To shown in Figure 7, support is the member in band chamber as Fig. 5, and its upper right corner has extension, the top of extension has pin-and-hole, and lower left quarter has waist through hole 9, and the side has elongated hole 10, the axes intersect of waist through hole 9 and elongated hole 10, the upper left corner is provided with groove, groove bottom porose 11; Nutplate 2 places the waist through hole 9 of support, and nutplate can do the rotation of certain angle around vertical line of symmetry of waist through hole, to adapt to the needs of regulating door leaf and the distance of following rail.

As shown in Figure 3, spring 6 is a flat spring, the one end turns back into bending part 7, and the termination outwards turns up and form projection 8, is installed in the hole 11 of groove bottom of support, the other end becomes the button-head of bending, this termination leans on a cross wall of sliding door lower frame, can play good cushioning effect, and wheel assembly has been played the effect of exerting pressure downwards, make pulley when sliding, be close to track, anti-limited slip wheel derailing.

As shown in Figure 2, for the utility model is regulated the front-back direction contrast, real diagram is the state before regulating, and two point slip figure is the state after regulating, the elongated hole that adjustment screw is passed support cooperates with nutplate, and nutplate has been rotated certain angle in waist through hole; The support pivot pin that rotates has rotated certain angle, thereby makes the distance increase of door leaf and following rail.

Described U type frame lower, transverse is symmetrically arranged with two pin-and-holes, be provided with a pin-and-hole on longitudinal centre line top, pin-and-hole on roller pin is passed on the pin-and-hole of support extension and the U type frame vertically is rotationally connected support and U type frame, can realize the effect of the automatic adjustment of sister block, make sister block stressed more even.
