Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example one

As shown in the accompanying drawing 1, the utility model provides a pair of fastener, including fastener 1 body, as shown in fig. 1, fastener 1 body is formed according to specific figure from thickness 1.2 mm's galvanized sheet unloading through the laser machine, and the both sides of fastener 1 body are bent downwards and are formed lock limit 11, and breach 12 has all been seted up to the one end of lock limit 11, forms constant head tank 13 between two breach 12, and slot 14 has all been seted up to the other end on lock limit 11, and slot 14 cuts apart into the portion of compressing tightly 15 and the hem portion 16 with lock limit 11.

The fastener 1 is used for connecting the main frame 2 and the auxiliary frame 3, reducing excessive punching on the main frame 2 and the auxiliary frame 3 and installing fixing screws; the positioning groove 13 is used for positioning with the main frame 2 to prevent the fastener 1 from moving.

The middle part of the fastener 1 body is provided with a mounting hole 17, so that the fastener 1 body is fixed with the mounting belt 4 conveniently.

One end of the fastener 1 body is provided with a prepared mounting hole 18, and the prepared mounting hole 18 is close to the slot 14. The preliminary mounting holes 18 are mainly used to fix the main frame 2 in the case where the mounting band 4 cannot be used, and are not used substantially, but are used for preliminary purposes.

Example two

As shown in fig. 2 to 6, the wafer door frame includes a plurality of fasteners 1 in the first embodiment, and further includes a main frame 2, an auxiliary frame 3 and a mounting tape 4, as shown in fig. 2, one side of the main frame 2 is folded to form a locking step 21, and an accommodating groove 22 is formed between the locking step 21 and the main frame 2. Before welding, the two hem portions 16 on the fastener 1 are bent by hands, the fastening edge 11 of the fastener 1 is welded and fixed in the accommodating groove 22, and the clamping step 21 is clamped in the positioning groove 13 to prevent the fastener 1 from moving, so that the fastener 1 and the main frame 2 are welded and fixed together.

As shown in fig. 3 to 5, the mounting strip 4 is a galvanized plate with a thickness of 0.8mm, one end of the mounting strip can be fixed by welding through rivets, the advantage of using rivets to fix the mounting strip 4 is that the mounting strip 4 can rotate, the fixing direction has more choices, and fixing the mounting strip 4 by welding or other methods can cause inconvenience in installation. The fixing part 41 is fixed on the fastener 1, the other end of the mounting belt 4 is bent to form the fixing part 41, the fixing part 41 is used for being fixed with the wall 5, and fixing screws are used for fixing the main frame 2 on the wall 5. Through the use of the fastener 1 and the mounting belt 4, the mounting hole 17 on the front surface of the main frame 2 is eliminated, and the problem that the mounting hole 17 leaks outwards and is not attractive is fundamentally solved. Certainly, also can be through the fixed main frame 2 of the mode of beating the foaming glue and the subframe 3, the advantage of using the fixed door frame of installation area 4 is, in case the foaming glue is invalid, because main frame 2 and subframe 3 are being fixed to installation area 4 in addition, can not lead to the door frame to rock the unstability.

As shown in fig. 3 to 6, the other side of the main frame 2 is bent to form a clamping portion 23, the clamping portion 23 is located between the bent portion 16 and the pressing portion 15, one side of the sub-frame 3 is bent to form a connecting portion 31, and the connecting portion 31 is inserted between the pressing portion 15 and the clamping portion 23. The auxiliary frame 3 is clamped tightly by the pressure between the pressing part 15 of the fastener 1 and the clamping part 23 of the main frame 2, the installation of the door frame is completed, the number of the mounting holes 17 on the auxiliary frame 3 is further reduced, the number of the required fixing screws in the whole installation process is greatly reduced, the installation is more convenient and faster, and the problems that the main frame 3 and the auxiliary frame 3 are complex to install and the mounting holes 17 are not beautiful due to leakage are fundamentally solved.

As shown in fig. 6, one side of the locking step 21 is bent to form a first surrounding edge 24, one side of the sub-frame 3 is bent to form a second surrounding edge 32, and the first surrounding edge 24 and the second surrounding edge 32 further play a role in stabilizing the main frame 2 and the sub-frame 3, so as to prevent the door frame from shaking unstably.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
