Described gear and tooth bar are positioned at shell, and described shift fork stretches out inside shell.

Described connection support is inverted L shape.

The beneficial effects of the utility model are:

This utility model changes the tradition lofty way being installed on bar surface of handle, make door and window surface more succinct, especially achieve perfect unified appearance with the Built-in hinge of the sliding support of swinging-out casement window, inwardly opened window, more perfect solving in double window, Multi-layer window causes the excessive defect even affecting keying of section material section because tradition handle protrudes Surface of profile.

Accompanying drawing explanation

Below in conjunction with the accompanying drawings this utility model is further described:

Fig. 1 is Split type structure schematic diagram of the present utility model；

Fig. 2 is this utility model and sash profile carries out the Split type structure schematic diagram that assembles；

Fig. 3 is the structural representation during this utility model uses.

In figure, 1 sash profile, 2 drive links, 21 T parts, 3 shells, 4 connect support, 41 lateral parts, 42 vertical sections, 5 press strips, 6 handle handles, 7 holes, 8 gears, 9 tooth bars, 10 shift forks, 11 strip doors.

Detailed description of the invention

Accompanying drawing is specific embodiment of the utility model.nullAs shown in Figure 1 to Figure 3，This kind of concealed handle，Hide in the press strip 5 being arranged on sash profile 1，The inner side of sash profile 1 is provided with the drive link 2 of T part 21，The T part 21 of drive link 2 stretches out from sash profile 1 and can vertically move along sash profile 1，A connection support 4 is fixed in the press strip side of sash profile 1，Connecting support 4 can be to be multiple framework form，At this as a example by inverted L shape: the standing portion 42 connecting support 4 of inverted L shape is connected by securing member with sash profile 1，Lateral part 41 is positioned at the upper end of vertical section 42，Connect between lateral part 41 and vertical section 42 and have shell 3，The press strip 5 that shell 3 and connection support 4 are positioned in sash profile 1，Sash profile 1、Connect same section inside support 4 and shell 3 and have the through hole of same strip，So that the T part 21 of drive link 2 passes and moves，The lateral part 41 connecting support 4 rides on the upper surface of shell 3，It is provided with handle handle 6 on support 4 connecting，Connect and also have hole 7 on support 4，The gear 8 and tooth bar 9 meshed together it is provided with in shell 3，By being fixed together through the rotating shaft in hole 7 between gear 8 and handle handle 6，Tooth bar 9 is provided with shift fork 10，T part 21 on shift fork 10 and drive link 2 engages；Press strip 5 has and can hold the strip door 11 that handle handle 6 produces.

During use, open strip door 11, handle handle 6 is produced from strip door 11, gear 8 and handle handle 6 synchronous axial system, engagement due to tooth bar 9 with gear 8, tooth bar 9 moves linearly simultaneously, then drives T part 21 and drive link 2 synchronizing moving further through shift fork 10, it is achieved that the keying of handle.

In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
