Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

At present, steel door welding mainly welds accessories such as connecting pieces, reinforcing plates for hardware installation, ash blocking boxes, installation fixing plates and the like to a door frame main body. The specific installation process and process of the ash blocking box are as follows:

first, the door frame has the opening, and the box welds in the back of door frame to make its inside ash blocking space and the opening of door frame face each other, with this ash blocking box can play the effect of keeping off the ash to the opening of door frame. In detail, in the prior art, a connection plate is welded in the opening, a through hole is formed in the center of the connection plate, and the ash blocking box is welded to the through hole. In addition, the connecting plate is still attached with the decorative board on the terminal surface that deviates from ash blocking box one side (i.e. the front side of door frame), covers the recess groove that forms between connecting plate and the door frame front through the decorative board to make the door frame have more sight.

However, the ash blocking box and the connecting plate are assembled and connected by welding, a large number of welding operations can reduce the manufacturing efficiency, and the welding cost can also improve the production cost of the door frame.

To the above technical problems, as shown in fig. 1, 2 and 3, the disclosure provides a welding-free structure of a door frame ash blocking box, which comprises a door frame main body 1 and an ash blocking box body 2, wherein the door frame main body 1 is provided with an opening 3. And the two sides of the opening 3 are provided with connecting plates 4, and the two sides of the ash blocking box body 2 are correspondingly provided with connecting lugs 5. When the ash blocking box body 2 and the door frame body 1 are assembled, the connecting plates 4 and the corresponding connecting lugs 5 are fixedly connected through the fasteners 6, so that the welding-free assembly operation of the ash blocking box body 2 and the door frame body 1 is realized.

For example, the connection plate 4 may be welded to the rear surface of the door frame body 1 and extend into the opening 3 as seen in the front projection direction of the door frame body 1. And the web 4 is preferably dimensioned to completely cover the width of the opening 3, so that the web 4 has a larger bearing area opposite the opening 3 for a more stable connection with the connecting lugs 5.

In order to enhance the ornamental value of the door frame, the decorative plate 9 is further included in the present disclosure, and as in the prior art, the decorative plate 9 of the present disclosure is also used to cover the recess groove formed between the connection plate 4 and the front surface of the door frame body 1. In contrast, the connecting lugs 5 are pressed between the decorative plate 9 and the connecting plate 4, so that the decorative plate 9, the connecting lugs 5 and the connecting plate 4 can be simultaneously and fixedly connected by the fastening pieces 6. The connecting lugs 5 are pressed and fixed between the decorative plate 9 and the connecting plate 4, so that the door frame main body 1 and the ash blocking box main body 2 are connected more firmly and reliably.

For example, the first fixing hole 7 is formed in the connecting lug 5, the second fixing hole 8 is correspondingly formed in the connecting plate 4, and the third fixing hole 17 is correspondingly formed in the decorative plate 9. The fastening member 6 may preferably be a fastening screw, so that the fastening screw may penetrate through the first fixing hole 7, the second fixing hole 8 and the third fixing hole 17 to fix the connecting lug 5, the connecting plate 4 and the decorative plate 9 relatively.

In addition, based on the overlapping setting of the decorative plate 9, the connection lugs 5 and the connection plate 4, in actual assembly, whether the decorative plate 9 is flush with the front face of the door frame body 1 can be controlled by selecting the thickness of the connection lugs 5, so that the situation that the decorative plate 9 is recessed in the recess groove (i.e., the situation that a step is formed between the end face of the decorative plate 9 and the front face of the door frame body 1) is difficult to occur in the prior art. For example, the attachment lugs 5 may be machined twice by a grinding machine to select a suitable thickness.

In some embodiments, the ash box body 2 includes a base plate 10, and a first main barrier 11, a first side barrier 12, a second main barrier 13, and a second side barrier 14 that are disposed at a side wall of the base plate 10 in order in a circumferential direction. For example, the first main barrier 11, the first side barrier 12, the second main barrier 13, and the second side barrier 14 are formed integrally with the substrate 10. When the ash blocking box body 2 is not formed, the first main baffle 11, the first side baffle 12, the second main baffle 13, the second side baffle 14 and the substrate 10 are positioned on the same plane, and then the first main baffle 11, the first side baffle 12, the second main baffle 13 and the second side baffle 14 are sequentially bent towards the same side, and the first main baffle 11, the first side baffle 12, the second main baffle 13 and the second side baffle 14 are enclosed to form an ash blocking space 15 required by the ash blocking box body 2.

Preferably, the end parts of the side baffle I12 and the side baffle II 14 are bent away from the ash blocking space 15 to form the connecting lug 5. Therefore, the ash blocking box body 2 is of an integrated structure and has the advantages of simple structure and ingenious assembly.

In addition, the first and second main shutters 11 and 13 each have an assembly gap 16 with the side wall of the opening 3 when seen in the front projection direction of the door frame body 1. That is, the width of the ash blocking box body 2 is smaller than the width of the opening 3, so that the ash blocking box body 2 is easier to be clamped into the opening 3, and the situation that the ash blocking box body 2 cannot be normally installed due to interference between the ash blocking box body 2 and the side wall of the opening 3 is difficult to occur.

The connecting port of the decorative plate 9 is accommodated in the dust blocking space 15 as seen in the front projection direction of the door frame body 1. That is, the size of the connecting opening of the decorative plate 9 is smaller than the size of the opening 3 of the dust blocking space 15, so that dust is not easy to leak from the assembly gap 16, and the welding-free structure of the door frame dust blocking box has high use reliability.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
