Detailed ways

In order to further understand the features and technical contents of the utility model, please refer to the following detailed description and accompanying drawings of the utility model. However, the attached drawings are only for reference and illustration, and are not intended to limit the utility model.

As shown in Figure 1, a kind of casement window handle comprises handle seat 10, handle handle 30, draw-in groove ring 50, lock core 70 and cog 90.

The handle 30 is connected with the handle seat 10, the handle seat 10 includes the cog 90 matched with the draw groove ring 50, the handle base 110, the handle seat cover 130 covered on the handle base 110 and The handle seat cushion 150 is accommodated in the handle seat cover 130 to fix the cogs 90 .

The handle seat 10 is installed on the casement window, and the handle handle 30 is installed on the handle seat 10, wherein the handle seat 10 can be a cylinder, a square column or other columns, and the figure shows a slightly deformed cylinder.

The handle 30 is formed by the extension of the handle seat 10, the card groove ring 50 is fixed on the handle seat 10, the lock core 70 is fixed in the handle handle 30, and a notch is provided in the card groove ring 50, therefore, along with the lock core 70 locking, the push rod 710 of the lock core 70 goes down to the notch of the groove ring 50 to limit the angle of rotation of the handle 30, and then the above-mentioned casement window handle will have a limit function , which can be used to restrict the opening state of the casement window.

Further, as shown in Figure 2, the lock cylinder 70 includes a locking structure 730 and a push rod 710 connected to the bottom of the locking structure 730, and the rotation of the locking structure 730 by the key drives the push rod 710 to go down, so that the push rod 710 abuts against the notch of the snap ring 50 to lock the rotatable handle 30, so that the handle cannot be rotated 360 degrees.

Further, as shown in FIG. 3 , the snap-in ring 50 is a hollow cylinder in a stepped state, that is to say, the snap-in ring 50 is composed of several hollow cylinders with successively increasing diameters, and one end of the snap-in ring 50 is a small-diameter The end face of the cylinder, and the other end is the end face of a large diameter cylinder.

Specifically, the large-diameter cylindrical end surface is provided with a large-angle slot 510 and/or a point notch 530 respectively, so as to limit the rotation of the handle 30 . Preferably, the large-angle slot 510 is a 180-degree slot, and the slot ring 50 is composed of two cylinders with different diameters.

Further, the large-angle locking groove 510 and the point notch 530 are arranged opposite to each other. Preferably, the middle position of the large-angle locking groove 510 is located at the same diameter as the point notch 530 .

Furthermore, when the lock cylinder 70 is in the open state, the handle 30 can be rotated 360 degrees to realize the conversion of the three states of the casement window: locking, casement opening and downward hanging.

When the above-mentioned casement window handle is applied to the down-hung inner casement window, when the down-hung inner casement window is in the down-hung state, the lock cylinder 70 is locked, and the ejector rod 710 of the lock cylinder 70 will be at a large angle. On the position of the draw-in groove 510, the boss structure in the cog 90 will cooperate with the push rod 710 so that the cog 90 cannot continue to rotate, limiting the handle to open the casement window to the flat open state.

When the above-mentioned casement window handle is applied to the inner casement lower-hung window, the inner casement lower-hung window is in the lower-hung state, the lock cylinder 70 is locked, and the push rod 710 of the lock cylinder 70 is in the point notch 530 On the position, make cog 90 can't continue to rotate, to limit handle to rotate.

The above-mentioned casement window handle includes a handle seat, a handle handle, a slot ring, a lock cylinder and a wheel tooth, and a notch is provided in the slot ring, and as the lock cylinder is locked, the push rod of the lock cylinder goes down To the notch of the card groove ring to limit the angle of rotation of the handle, and then provide a limit function for the handle of the casement window to limit the opening state of the casement window.

It can be known from technical common sense that the above-mentioned embodiments can be realized through other implementation modes without departing from the spirit or essential features thereof, so it should not be construed as limiting the patent scope of the utility model. Therefore, the specific embodiments disclosed above are just examples for those of ordinary skill in the art, and there may be some modifications, which are not the only ones. Changes within the scope of the present invention or within the equivalent scope all belong to the present invention. Protection scope of utility model.
