[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-10This utility model provides a technical solution: a threaded locking structure, including a spring-loaded cover 1, a drinking spout sealing plug 2, a cup lid 3, a locking tongue 4, a compression spring 5, a drinking spout 6, a cup mouth 7, a torsion spring 8, and a pin 9. The spring-loaded cover 1 is rotatably connected to one side of the cup lid 3, and the drinking spout sealing plug 2 is installed in the middle of the inside of the spring-loaded cover 1. The drinking spout 6 is installed inside the cup lid 3, and the locking tongue 4 is installed on one side of the drinking spout 6. The compression spring 5 is installed at the lower part of the locking tongue 4. The cup mouth 7 is installed on the outer side of the bottom of the drinking spout 6. The outer ring of the cup mouth 7 is provided with an external thread, and the inside of the cup lid 3 is provided with an internal thread that mates with the external thread.

[0026] In this example, the cup lid 3 and the pop-up lid 1 are movably connected by a pin 9, and a torsion spring 8 is provided outside the pin 9 to facilitate the opening of the cup lid 3.

[0027] In this example, the lower part of the pop-up lid 1 is provided with a first rib 101, which can match the first groove 403. The upper part of the internal thread of the cup lid 3 is provided with a second rib 301. The top of the locking tongue 4 is provided with a first groove 403 corresponding to the first rib 101, and the lower part of the locking tongue 4 is provided with two third ribs 402. At the same time, the side of the third rib 402 is a first side surface 401. The side of the drinking spout 6 is provided with two second grooves 601 that match the third rib 402, and the side of the drinking spout 6 is a second side surface 602. The inner ring protrusion of the cup mouth 7 is a third side surface 701.

[0028] Working principle: This structure has three components: a pop-up lid assembly, a cup lid assembly, and a cup mouth. The pop-up lid assembly has a pop-up lid 1 and a drinking spout sealing plug 2. The cup lid assembly has a cup lid 3, a locking tongue 4, a pressure spring 5, and a drinking spout 6. First, insert the drinking spout sealing plug 2 into the pop-up lid 1 to complete the assembly. Then, place the pressure spring 5 into the drinking spout 6, and then insert the locking tongue 4. The locking tongue 4 has two third protrusions 402, and the drinking spout has two second grooves 601. The third protrusions 402 are limited by the second grooves 601 on the drinking spout. At this time, the locking tongue 4 can only move up and down under the force of the pressure spring 5. The cup lid 3 has second protrusions 301. When the assembled drinking spout 6 is placed into the cup lid 3, the second side 602 on the drinking spout 6 will engage with the second protrusions 301 on the cup lid 3. Therefore, the cup lid assembly is completed (as shown). Figure 8 , 9 Install the torsion spring 8 onto the cup lid assembly, then install the spring-loaded lid assembly, and finally insert the pin 9 to complete the cup lid assembly. The cup lid 3 and the cup mouth 7 are fixed together by internal and external threads. When using this threaded locking structure, when the spring-loaded lid 1 is closed, the spring-loaded lid 1 is... Figure 11When the locking teeth are engaged, the latch 4 is pressed down by the first protrusion 101 on the pop-up lid 1. The cup rim has a third side surface 701, and the latch 4 has a first side surface 401. At this time, the third side surface 701 on the cup rim 7 and the first side surface 401 on the latch 4 form a limiting position, i.e., threaded locking, and cannot be unscrewed. When the pop-up lid 1 is opened, the first protrusion 101 on the pop-up lid 1 will leave the first groove 403 on the latch. At this time, the latch 4 will be popped up by the compression spring 5, and the first side surface 401 on the latch 4 will leave the third side surface 701 on the drinking spout, allowing the threads to be unscrewed (e.g., ...). Figure 8-10 (As shown), this completes the entire work, and the contents not described in detail in this specification are prior art known to those skilled in the art.
