[0037] The following will be described in detail with reference to the accompanying drawings. Figures 1-5 The present application will be further described in detail.

[0038] An embodiment of the present application discloses a lock structure and a storage bag. Referring to Figure 1 , Figure 2 A storage bag comprises a bag body 3 and a lock structure fixedly connected to an opening of the bag body 3, and the lock structure comprises a plug-in 1 and a connector 2. When in use, an article is placed into the bag body 3, the plug-in 1 is aligned with the connector 2, and the connector 2 is pressed, so that the bag opening is closed and the sealing operation is completed. The lock structure of the present application can also be applied to product theft prevention and is suitable for supermarkets, clothing stores and the like.

[0039] Referring to Figure 2 , Figure 3The plug-in part 1 comprises a pressing shell 11, a plug pin 12 arranged in the pressing shell 11, a pressing part 13 fixedly connected to one end of the plug pin 12, and a first spring 14 sleeved on the plug pin 12, one end of the first spring 14 abutting against the inner wall of the pressing shell 11, and the other end abutting against the pressing part 13. One end of the pressing shell 11 is provided with a first through hole 111 for the plug pin 12 to pass through, and the other end is provided with a pressing hole 112 for the pressing part 13 to pass through. When plugging, only the pressing part 13 needs to be pressed, at this time the plug pin 12 can pass out of the first through hole 111 into the inside of the connector 2, thereby completing the plugging operation. When not plugging, the first spring 14 props the pressing part 13 away from the first through hole 111, so that the plug pin 12 is always retracted in the pressing shell 11, thereby preventing the plug pin 12 from being exposed to scratch the user and improving the safety of use.

[0040] With reference to Figure 2 , Figure 3 The pressing part 13 is fixedly connected with a limiting ring 131 in the circumferential direction. When the first spring 14 props up the pressing part 13, the upper surface of the limiting ring 131 abuts against the inner top wall of the pressing shell 11, thereby preventing the limiting part and the plug pin 12 from being pulled out of the pressing hole 112, and ensuring the safety when using the plug-in part 1.

[0041] With reference to Figure 2 , Figure 3 The end of the plug pin 12 is provided with a guide angle 121, which can help the plug pin 12 to automatically align during plugging, reduce the difficulty of alignment during plugging, and ensure the convenience during plugging. The inner diameter of the first through hole 111 gradually increases away from the side of the connector 2, thereby facilitating the plug pin 12 to pass out of the inside of the pressing shell 11, and improving the smoothness during plugging.

[0042] With reference to Figure 4 , Figure 5The abutting piece 2 comprises an abutting shell 21 and a clamping assembly 22 arranged in the abutting shell 21 for fixing the plug pin 12, the abutting shell 21 is provided with a second through hole 211 for the plug pin 12 to pass through near the side close to the pressing shell 11, the clamping assembly 22 comprises a first sleeve 221, a second sleeve 222 sleeved outside the first sleeve 221 and a mounting seat 223 inside the two sleeves, the inner diameter of the first sleeve 221 gradually increases in the direction away from the plug-in piece 1, the first sleeve 221 is provided with a third through hole 2211 for the plug pin 12 to pass through, the second sleeve 222 is provided with a second spring 224 inside, one end of the second spring 224 abuts against the inner bottom wall of the second sleeve, and the other end abuts against the mounting seat 223, the mounting seat 223 is provided with a plurality of clamping balls 225 close to the side of the first sleeve 221, and the mounting seat 223 is fixedly connected with a plurality of L-shaped limiting plates 226 close to the side of the first sleeve 221 for preventing the clamping balls 225 from falling off, and an opening is formed between every two limiting plates 226 for the clamping balls 225 to enter and exit. When plugging, the plug pin 12 enters the mounting seat 223, the clamping balls 225 are pressed to move towards the side wall of the first sleeve 221 by the plug pin 12, the mounting seat 223 is always pressed to the inner wall side of the first sleeve 221 by the second spring 224, so that the activity space of the clamping balls 225 is compressed, at this time, the clamping balls 225 abut against the inner wall of the first sleeve 221 and the side wall of the plug pin 12 at the same time, the clamping balls 225 and the plug pin 12 are tightly matched by friction force and cannot continue to move, so as to ensure the stability of plugging. When the plug pin 12 needs to be pulled out, a strong magnet is used to attract the mounting seat 223, the second spring 224 is compressed, the activity space of the clamping balls 225 is expanded, the friction force between the clamping balls 225 and the plug pin 12 is reduced, and the plug pin 12 is bounced back into the pressing shell 11 by the first spring 14.

[0043] With reference to Figure 4 , Figure 5 The bottom of the second sleeve 222 is provided with a fourth through hole 2221 for the plug pin 12 to pass through, the second sleeve 222 is made of transparent plastic material, and the mounting seat 223 is made of iron.

[0045] With reference to Figure 4 , Figure 5The outer wall of the first sleeve 221 is connected with a convex ring 2213, and the inner wall of the second sleeve 222 is fixedly connected with a groove 2222 in the circumferential direction for placing the convex ring 2213, and the width of the groove 2222 is greater than the thickness of the convex ring 2213. When the second sleeve 222 is sleeved with the first sleeve 221, the groove 2222 can facilitate installation, and the convex ring 2213 can be obliquely inserted into the groove 2222 and then returned to normal, so as to complete the assembly of the first sleeve 221 and the second sleeve. Secondly, when plugging, the convex ring 2213 can move in the groove 2222, and the pin 12 is inserted to press down the clamping assembly 22, and the groove 2222 allows the first sleeve 221 to have a certain space for pressing down, so as to facilitate the pin 12 to enter the mounting seat 223 through the guide surface 2212.

[0046] With reference to Figure 4 , Figure 5 The inner bottom wall of the abutting shell 21 is provided with a pad 213, and the pad 213 is used for abutting with the second sleeve 222. The pad 213 is a nut. When the strong magnet attracts the mounting seat 223, the pad 213 can lift the clamping assembly, so that the pin can enter the clamping assembly more quickly, and the locking is facilitated. The nut is used as the pad 213, the size of the nut is various, and it is easy to find a suitable size of the nut, without the need of additional customized parts, so as to reduce the production cost. Secondly, the screw hole in the middle of the nut can also be used for positioning the clamping assembly 22, and the assembly is facilitated.
