Problems solved by technology

[0003]The expansion plug is mainly used to fix the object. When the fastening screw is inserted, the plug will expand, and after expansion, it will be fixed on the corresponding object, making the object more tightly fixed. However, after the commonly used expansion plug is used up, the tail end is inside the object, so except for the fastening screws, the others cannot be recycled, which will cause a lot of waste

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the invention is described in detail:

[0017] The present invention designs an expansion plug for windows. The expansion plug is composed of two parts. After being fixed, the former part can be disassembled for further use, so it does not need to be discarded completely, and thus resources can be greatly saved.

[0018] As a specific embodiment of the present invention, the present invention provides a structural schematic diagram such as figure 1 An expansion plug for a window is shown, including an expansion plug 1, a locking tooth 3, a brake tongue 4, a rear seat 10 and a fastening screw 11. There is a slot 2 in the middle of the expansion plug 1, and the two sides of the expansion plug 1 are There are locking teeth 3 and brake tongues 4. One end of the expansion plug 1 is a connecting part 5. There are screw holes 6 and screw guide holes 7 in the connecting part 5 of the expansion plug 1. The screw guid...

Abstract

The invention provides an expansion plug for windows. The expansion plug for the windows comprises an expansion plug body, a latch, a barking tongue, a back base and a fastening screw, wherein a seam groove is formed in the middle of the expansion plug, the latch and the barking tongue are arranged on two sides of the expansion plug, one end of the expansion plug is a connecting part, a screw hole and a screw guiding hole are formed inside the connecting part of the expansion plug, the screw guiding hole is formed between the screw hole and the seam groove, the big opening of the screw guiding hole is connected with the screw hole, the small opening of the screw guiding hole is connected with the seam groove, a back base connecting part is arranged at the front end of the back base, threads are arranged on the back base connecting part, the back base connecting part is installed inside the screw hole, through holes are formed inside the back base and the back base connecting part, and the fastening screw penetrates through the through holes of the back base and the back base connecting part. The expansion plug for the window is designed, the expansion plug is composed of two parts, after the expansion plug is fixed, a front part of the expansion plug can be dismantled and used continuously, therefore, the expansion plug for the windows does not need to be completely abandoned, and then resources can be greatly saved.

Description

technical field [0001] The invention relates to the field of expansion and fixation structures, in particular to an expansion plug for windows. [0002] Background technique [0003] The expansion plug is mainly used to fix the object. When the fastening screw is inserted, the plug will expand, and after expansion, it will be fixed on the corresponding object, making the object more tightly fixed. However, after the common expansion plug is used up, the tail end is inside the object. , so except for fastening screws, others cannot be recycled, which will cause a lot of waste. [0004] Contents of the invention [0005] In view of the above problems, the present invention designs an expansion plug for windows. The expansion plug is composed of two parts. Use expansion plugs, including expansion plugs, locking teeth, brake tongues, back seats and fastening screws. There are slots in the middle of the expansion plugs, locking teeth and braking tongues are arranged on both ...
