Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, the lower hinge of the inwardly opened and inwardly inverted window comprises a frame fixing plate 1, a main support plate 2, a long support plate 3, a short support plate 4 and a fan fixing plate 5, wherein the main support plate 2, the long support plate 3 and the short support plate 4 form a link mechanism. The main support plate 2 and the long support plate 3 are crossed and are rotationally connected through rivets, one end of the long support plate 3 is rotationally connected with the frame fixing plate 1 through rivets, the other end of the long support plate 3 is rotationally connected with the fan fixing plate 5 through rivets, one end of the main support plate 2 is rotationally connected with the fan fixing plate 5 through the short support plate 4 by rivets, and the other end of the main support plate 2 is installed on the sliding groove 7 through the sliding block 6. A positioning block 8 is fixed in the chute 7, and when the link mechanism is unfolded until the sliding block 6 is limited on the positioning block 8, the fan fixing plate 5 is 90 degrees relative to the frame fixing plate 1, namely, the fan can be unfolded by 90 degrees; if the positioning block 8 is not arranged, the window sashes can be unfolded by 180 degrees.
As shown in fig. 1, 2 and 3, the frame fixing plate 1 is provided with a chute 7 along the length direction thereof, the chute 7 penetrates through the frame fixing plate 1, the chute 7 is provided with a bending strip 7a along the length direction thereof, and the sliding block 6 is provided with a sliding way 6a matched with the bending strip 7 a. The sliding block 6 and the sliding groove 7 have two assembly modes:
As shown in fig. 2 and 3, in the first assembly mode, a bending strip 7a is arranged on one side of a chute 7, a slideway 6a is arranged on one side of a sliding block 6, a step 6b is arranged on the other side of the sliding block 6, and the step 6b is hooked on a frame fixing plate 1;
As shown in fig. 4 and 5, in the second assembly mode, symmetrical bending strips 7a are arranged on two sides of the chute 7, symmetrical sliding ways 6a are arranged on two sides of the sliding block 6, and the sliding ways 6a correspondingly abut against the bending strips 7a.
As shown in fig. 1-5, when the sliding block 6 slides along the sliding groove 7, the sliding block 6 slides along the bending strip 7a through the sliding way 6a, and the bending strip 7a is a smooth surface, so that the contact of a punching rough surface in the sliding groove is avoided, and the abrasion of the sliding block is greatly reduced; the sliding block 6 is hooked with the frame fixing plate 1 through the step 6b, the sliding surface is the frame fixing plate 1, the frame fixing plate 1 is a smooth surface, the contact of the punching rough surface inside the sliding groove is avoided, and the abrasion of the sliding block is greatly reduced.
