DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4As shown, the utility model provides a waterproof connector, including a shell 1, a first connecting tube 11 is fixedly installed on one side of the shell 1, and a second sealing ring 5 is fixedly installed on the end of the shell 1 away from the first connecting tube 11. By setting the second sealing ring 5, gaps are avoided when the cable enters the shell 1, thereby achieving a waterproof effect; a second connecting tube 12 is provided at the end of the first connecting tube 11 away from the shell 1, and a first sealing ring 3 is fixedly installed on the side of the second connecting tube 12 away from the first connecting tube 11. By setting the first sealing ring 3, gaps are avoided when the cable enters the second connecting tube 12, thereby achieving a waterproof effect; a supporting ring 13 is fixedly installed inside the second connecting tube 12, and a ring-shaped fixed rod 14 is fixedly installed on the outer side of the supporting ring 13, and a movable rod 1 is movably inserted inside the fixed rod 14. 5. A fixing plate 16 is fixedly installed at one end of the movable rod 15 close to the inner wall of the second connecting tube 12. The fixing plate 16 penetrates the second connecting tube 12. The support ring 13 and the fixing plate 16 are fixedly connected by a spring 17. A rotating sleeve 18 is rotatably sleeved on the outer side of the second connecting tube 12. An annularly distributed empty groove 19 is provided on the outer side of the rotating sleeve 18. A plurality of empty grooves 19 and a plurality of fixing plates 16 are staggered. An annularly distributed clamping groove 191 is provided on the outer side of the first connecting tube 11. The clamping groove 191 and the fixing plate 16 are used in conjunction. A fixing sleeve 192 is fixedly installed on the outer side of the first connecting tube 11. A through groove 193 corresponding to the clamping groove 191 is provided on the outer side of the fixing sleeve 192. An elastic sheet 194 is fixedly installed in the through groove 193. A push block 195 is fixedly installed on the side of the elastic sheet 194 close to the first connecting tube 11.

[0018] A circularly distributed positioning rod 2 is fixedly installed on one side of the rotating sleeve 18 close to the first connecting pipe 11 , and a circularly distributed positioning groove 21 is provided on one side of the first connecting pipe 11 close to the second connecting pipe 12 . The positioning rod 2 and the positioning groove 21 are used in conjunction with each other.

[0019] The outer side of the support ring 13 is fixedly mounted with connecting rods 4 distributed in an annular manner. There are four connecting rods 4 . The connecting rods 4 are fixedly connected to the inner wall of the second connecting tube 12 . The support ring 13 can be fixed by providing the connecting rods 4 .

[0020] There are four fixing rods 14 , and there are four empty slots 19 and four clamping slots 191 , which improves the stability when the second connecting pipe 12 and the first connecting pipe 11 are connected.

[0021] Working principle: In actual use, the second connecting tube 12 is inserted into the first connecting tube 11 until the protrusion of the rotating sleeve 18 contacts the first connecting tube 11, and then the rotating sleeve 18 is rotated. At this time, the empty slot 19 rotates with the rotating sleeve 18. When the empty slot 19 rotates to a certain distance and coincides with the fixed plate 16, the compressed spring 17 releases the elastic force, driving the fixed plate 16 to move away from the support ring 13. At the same time, the movable rod 15 moves with the fixed plate 16 to prevent the fixed plate 16 from shaking during the movement. When the fixed plate 16 moves to a certain distance and is stuck in the slot 191, the second The connecting tube 12 is fixed. When it needs to be disassembled, the elastic sheet 194 is pressed to drive the push block 195 to move toward the slot 191 until the fixing plate 16 is pushed out of the slot 191. Then the second connecting tube 12 is pulled out to complete the disassembly of the second connecting tube 12. The fixing sleeve 192 is provided to prevent the slot 191 from being exposed to the outside, so that the waterproof function can be achieved while facilitating disassembly. The positioning rod 2 and the positioning slot 21 are provided so that the second connecting tube 12 can find a fixed angle when inserted into the first connecting tube 11, thereby facilitating the fixing plate 16 to be smoothly inserted into the slot 191.
