[0016] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A door and window stile 5 connector includes a connecting body 1, a movable tongue 2 and a screw 4. The movable tongue 2 can be slidably connected to the inner side of the connecting body 1. A fixed installation hole 12 is opened at one end of the connecting body 1. The connecting piece is connected to the stile 5 by using a screw 4 matching the fixed installation hole 12. The other end of the connecting body 1 is provided with two claws 13 for connecting to the frame 3.

[0020] The connecting body 1 is U-shaped, including a fixing portion 11 and two arms 15 on both sides of the fixing portion 11. The two arms 15 and the fixing portion 11 are integrally formed. A circular fixing installation hole 12 for connecting to the middle bar 5 is opened on the fixing portion 11. A notch is opened on the fixing installation hole 12 near the side of the movable tongue 2. Three protruding claws 16 for engaging the middle bar 5 are arranged on the outer side of each arm 15. A claw 13 is arranged at one end of each arm 15 away from the fixing portion 11. The inner sides of the connection between the two arms 15 and the claws 13 extend toward each other to form a convex surface 14.

[0021] The movable tongue 2 is protruded near the notch of the fixing hole to form a clamping block 21, and the clamping block 21 is slidably set in the notch and extends into the cross-section of the fixed installation hole 12. When the screw 4 is screwed into the fixed installation hole 12, the clamping block 21 is squeezed by the screw 4 to cause relative movement between the movable tongue 2 and the connecting body 1. The movable tongue 2 shrinks in the convex surface 14 area of ​​the connecting body 1 to form a fastening inclined surface 23 that slides in fit with the convex surface 14. A fastening foot 22 is provided at one end of the movable tongue 2 close to the claw 13.

[0022] In order to improve the strength of the connecting piece, the movable tongue 2 and the connecting body 1 are processed by an integrated molding process. In order to further save materials, the middle part of the movable tongue 2 is left hollow, and the fixing foot 22 adopts a U-shaped structure.

[0023] The use of this utility model:

[0024] like Figure 2 , insert the claw 13 on the connecting body 1 into the groove of the frame 3, then snap the other part of the connecting piece onto the stile 5, align the fixing hole with the connecting hole on the stile 5, and use the screw 4 that matches the fixing hole to connect and fix the connecting piece and the stile 5 together. When the screw 4 is pushed into the fixing hole, the screw 4 squeezes the block 21 in the fixing hole, so that the movable tongue 2 and the connecting body 1 move relative to each other, so that the movable tongue 2 moves toward the frame 3. During the movement of the movable tongue 2, the fixing inclined surface 23 on the movable tongue 2 squeezes the convex surface 14 on the inner side of the connecting body 1, and the claw 13 is stretched to both sides, so that the claw 13 is clamped in the groove of the frame 3; at the same time, during the movement of the movable tongue 2, the fixing foot 22 close to the frame 3 is pressed against the frame 3, and the fixing foot 22 is subjected to the reaction force of the frame 3, so that the connecting body 1 moves toward the stile 5, so that the protruding part of the claw 13 close to the fixing hole 12 is abutted and tightened with the inner wall of the groove of the frame 3. When the frame 3 and the stile 5 need to be disassembled, the screw 4 in the fixing hole 12 is unscrewed, and the movable tongue 2 is moved toward the stile 5 by the reaction force of the frame 3, so that the claw 13 can be taken out from the groove of the frame 3.

[0025] Embodiment 2:

[0026] Different from the first embodiment, the fixing member in this embodiment adopts a conical pin, and the fixing installation hole 12 is a through hole. The shapes of the conical pin and the through hole can be circular, square or other shapes.

[0027] In this embodiment, the fixing member may also be a fixing rod with other inclined ends.

[0028] The utility model is made of elastically deformable material instead of rigid material.

[0029] The movable tongue 2 and the connecting body 1 are detachably connected, so when one of them fails, it is convenient for maintenance and replacement.

[0030] The above is only a preferred embodiment of the utility model.
