Golden Point Atom, like Yuema, is a brand from Zhongshan Xiaolan, the "Southern Lock", backed by Zhongshan, a mature hardware production base that has developed rapidly. It was founded in 2001, in 2007 independent research and development of the lock industry's first automated equipment production line, most of the products of the degree of automation production of more than 70%, the lock cylinder precision is high, the quality is very guaranteed. In addition, Golden Pin Atom is also one of the main drafting units of the industry standard GA/T 73-2015 "Mechanical Anti-theft Lock".
 
In the product line of exterior door locks, Golden Pin Atom is the brand with the most products in this list, with a total of 7 models. There is no clear series division of these 7 models, all of them are common multi-tongue door locks, using a deadbolt structure of 1 oblique tongue and 2 cylindrical tongues, and the lock cylinders are all C-level with the highest security. The main difference between them is that the lock body shell of the 3 products below 200 yuan is thinner, and the lock cylinder is a bullet lock, and the 4 products above 300 yuan use a thickened lock shell and a blade lock cylinder (no product in the 200~300 yuan range).
 
499 yuan of 221 is the highest price of the Golden Point atomic exterior door lock, and the biggest difference with the other 6 products is the use of idling lock cylinder technology. Generally speaking, thieves can further achieve the purpose of unlocking as long as they use the unlocking tool to turn the lock cylinder, while the idling lock cylinder technology makes the unlocking tool unable to find the focus point, and the lock cylinder cannot be rotated to further unlock, so that the door lock is more secure. In addition to 221, the other 3 exterior door locks of more than 300 yuan are not much different from each other, and the price is about 380 yuan, and consumers can choose according to the style.
 
Among the 3 exterior door locks below 200 yuan, Golden Point Atom 223 and 2016 are relatively worth buying, and the prices of both are around 180 yuan. They all use the "single-layer V-shaped marble" technology promoted by the Golden Dot Atom, which is combined with the eccentric and internal pressure square column locking structure of the lock cylinder key mouth, which is different from the common upper and lower marble structure locks, and is not easy to be opened by thief technology.
 
Finally, it is worth mentioning that there are many counterfeit and shoddy products on the market, and consumers should try to choose official and officially authorized channels when purchasing to avoid losses in the future.
