The second screen frame body 121 is a rectangular parallelepiped with an opening on one side, and the second limiting net 122 is located in the second screen frame body 121 and is connected to the bottom of the second screen frame body 121 perpendicular to the opening. The second limiting nets 122 are sequentially distributed in the length direction of the second screen frame 121 at intervals.

The second screen frame body 121 is larger than the first screen frame body 111, and a gap is formed between the inner wall of the second screen frame body 121 and the plurality of second limiting nets 122 to form a fitting groove 123.

Referring to fig. 1, the first filter screen frame 111 can be sleeved in the matching groove 123, and each first position-limiting net 112 is alternately located between two adjacent second position-limiting nets 122.

The toughening frame 100 can be used in cooperation with a toughening furnace, and is applied to toughening equipment for carrying out chemical toughening treatment on glass. This tempering frame 100 has abandoned the spacing mode of traditional V type rack, and has adopted the filter screen subassembly of two differences in size to nest each other, makes in less first filter screen framework 111 locates the cooperation groove 123 of great second filter screen framework 121 with its opening side cover, makes first spacing net 112 crisscross be located between two adjacent spacing nets 122 of second simultaneously, forms relatively confined tempering frame 100 like this, treats that toughened glass can locate between adjacent first spacing net 112 and the spacing net 122 of second. So press from both sides through two adjacent spacing nets and tightly treat toughened glass, can guarantee that glass can not move about at will because of the motion of dissolved salt liquid stream in the tempering process, can cut off each glass simultaneously through spacing net to ensure the independent tempering of every glass product, the product sticking problem can not appear, has avoided the product to scrap, has improved chemical tempering yield. In addition, because the distance between two adjacent spacing nets can be adjusted as required, the flexibility is high.

Specifically, on the basis that the first screen frame 111 can be sleeved in the fitting groove 123, the first screen frame 111 is further moved in the length direction relative to the second screen frame 121, and thus the distance between two adjacent limiting nets can be adjusted.

Referring to fig. 2 and 3, in some embodiments, a plurality of protruding positioning portions 1121 are disposed on the same side surface of each first limiting net 112 and each second limiting net 122. Referring to fig. 1, when the first filter screen frame 111 is sleeved in the matching groove, the positioning portion 1121 of the first position-limiting net 112 is disposed opposite to the positioning portion 1121 of the second position-limiting net 122, so that a clamping space (not shown) is formed between the adjacent first position-limiting net 112 and the second position-limiting net 122, where the positioning portions 1121 are disposed opposite to each other. The clamping space is used for placing glass to be toughened.

It can be understood that the adjacent first limiting net 112 and the second limiting net 122, i.e. the adjacent two limiting nets, which are oppositely arranged by the positioning portion 1121, have two opposite surfaces facing each other.

Because the distance between two adjacent spacing nets can be adjusted as required, the flexibility is high, and the location effect of the contact of a plurality of location portions 1121 is better, so that the device can be suitable for tempering of ultrathin flexible glass. In addition, the first screen frame 111 is moved in the longitudinal direction relative to the second screen frame 121, so that the adjacent first limiting nets 112 and the adjacent second limiting nets 122, which are arranged opposite to the positioning portions 1121, are close to each other, and the glass to be tempered, which is located in the clamping space, can be firmly clamped. Adopt this tempering frame 100 to carry out the chemical tempering to flexible glass, can realize flexible glass's one shot tempering shaping, reduce the secondary and throw the material risk, and then also reduced the extra loss of man-hour, auxiliary material etc, reduced the fragment rate, improved nature glass's tempering processing procedure yield, and then be favorable to improving flexible glass's output, promote ultra-thin flexible glass's application on a large scale.

Referring to fig. 1, the positioning portions 1121 on two opposite surfaces of the adjacent first limiting nets 112 and the second limiting nets 122 are disposed in a one-to-one correspondence manner, so as to be used for respectively abutting two surfaces of the glass to be tempered. Through the one-to-one correspondence of the positioning portions 1121 on the two opposite surfaces of the two adjacent limiting nets, one surface of the glass to be toughened and the other surface opposite to the surface of the glass to be toughened are abutted to the positioning portions 1121 in corresponding areas, so that a good limiting effect is achieved.

Referring to fig. 4, in some embodiments, the positioning portions 1121 are sequentially distributed on the edge of the limiting net. The edge of the glass is fixed by the positioning portions 1121, and the positioning effect is good.

In some embodiments, each limiting net includes an outer frame body 1122 and an inner supporting bar 1123, the inner supporting bar 1123 is connected to the inner side of the outer frame body 1122, and the positioning portion 1121 is disposed on the outer frame body 1122.

Further, the outer frame body 1122 is rectangular. Further, the inner support bars 1123 are plural, such as two inner support bars 1123 for connecting opposite sides of the outer frame body 1122 and two inner support bars 1123 for connecting opposite corners of the outer frame body 1122. Further, four internal support bars 1123 are fixed at the same point.

Further, positioning portions 1121 are provided at four corners of the outer frame 1122. Further, each side of the outer frame 1122 is also provided with a positioning portion 1121 between two adjacent corners.

In this way, the guide posts 1114 can function to contact and guide the second screen frame body 121 when the first screen frame body 111 is moved in the longitudinal direction with respect to the second screen frame body 121 while functioning to support the stopper net.

Referring to fig. 5 and 6, further, the guiding stud 1114 is a cylinder. Guide post 1114 includes first and second sub-columns 1113, 1115, first and second sub-columns 1113, 1115 having axially extending grooves that mate with first and second sub-columns 1113, 1115 such that the grooves mate to form an inner bore; the guide post 1114 is sleeved on the filter screen frame body through an inner hole.
