Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0031] Example 1, please refer to Figures 1 to 5 , the present utility model is a storage structure of a multifunctional automatic pen - type syringe, including an outer shell 1 and a pen cap 101 sleeved on the bottom of its outer wall. A placing groove 104 is arranged below the outer wall on one side of the outer shell 1. A medicine tube 107 is installed inside the placing groove 104. The inner walls on both sides of the placing groove 104 are movably connected to the outer wall of the rotating cover 105 through hinges. A tightening component 2 is arranged at the bottom end inside the outer shell 1; the tightening component 2 includes a docking block 201 and a docking groove 201a arranged at the center of its top. A fixed plate 202 is arranged with a gap directly below the docking block 201.

[0032] Specifically, a connecting ring 102 is fixedly connected to the bottom of the outer shell 1. The outer wall of the connecting ring 102 is meshed and connected with the syringe tube 103 through threads. Magnetic strips 105a are embedded in the central positions of the opposite end faces of adjacent rotary covers 105. A clamping groove 105b is arranged above the inner wall of the rotary cover 105, and an adjusting groove 106 is arranged below the inner wall of the outer shell 1. A clamping plate 107a is fixedly arranged above the outer wall of the medicine tube 107, and a rubber stopper 107b is arranged at the top end inside the medicine tube 107. A driving rod 108 is arranged above the inner part of the outer shell 1; among them, the top edge of the adjusting groove 106 and the top edge of the clamping groove 105b are horizontally arranged, and the internal height of the adjusting groove 106 is higher than the internal height of the clamping groove 105b. The clamping plate 107a is located inside the clamping groove 105b and the adjusting groove 106. Magnetic blocks are embedded in the central positions of the opposite end faces of the rubber stopper 107b and the driving rod 108. The central positions of the opposite end faces of the docking block 201 and the fixing plate 202 are connected through a connecting hose 203. The upper surface of the fixing plate 202 is fixedly connected with pressing telescopic rods 204 at equal intervals along the circumferential direction. A pressing spring 205 is sleeved outside the outer wall of the pressing telescopic rod 204. The telescopic end of the pressing telescopic rod 204 is fixed on the lower surface of the docking block 201. The pressing spring 205 is located between the lower surface of the docking block 201 and the upper surface of the fixing plate 202. The outer wall of the fixing plate 202 is fixed on the inner wall of the outer shell 1.

[0033] Further, two groups of rotary covers 105 are provided, which can be rotated to open and close. The syringe tube 103 and the connecting ring 102 are connected through threads. Under the action of the magnetic strip 105a, the rotary cover 105 can be stably closed. The clamping plate 107a is clamped inside the clamping groove 105b and the adjusting groove 106. When the rotary cover 105 is opened, the clamping plate 107a can be adjusted up and down inside the adjusting groove 106. The rubber stopper 107b and the driving rod 108 are magnetically connected through magnetic blocks. The driving rod 108 is a prior art, so no more details will be described here. When the docking block 201 moves, the connecting hose 203 can ensure the stable flow of the liquid medicine. The pressing telescopic rod 204 plays a role in limiting the pressing spring 205. Under the elastic performance of the pressing spring 205, the medicine tube 107 can be forced and pressed against the top of the placing groove 104 to improve the stability.

[0034] The operation process of this embodiment is as follows: first, the rotating covers 105 on both sides of the placement slot 104 are rotated and opened under the action of the hinges, and then the docking nozzle 301 at the bottom of the medicine tube 107 is inserted into the docking slot 201a on the surface of the docking block 201, and then the medicine tube 107 is pressed downward. The medicine tube 107 is pushed downward by the force to push the docking block 201 at the bottom thereof, and the downward movement of the docking block 201 will squeeze the tightening telescopic rod 204 and the tightening spring 205 located below it. At this time, there is a certain space between the top of the medicine tube 107 and the top of the placement slot 104, and then the medicine tube 107 can be pushed into the placement slot 104, and the pressure on the medicine tube 107 is stopped after it is placed. At this time, the external force disappears in the abutment spring Under the action of its elastic properties, the docking block 201 can be bounced upward, and the top of the medicine tube 107 can be against the top of the placement groove 104, and then the rotating cover 105 can be rotated again to cover the outside of the placement groove 104 and the medicine tube 107. At the same time, the card slot 105b on the inner wall of the rotating cover 105 will be stuck on the outside of the card plate 107a on the outer wall of the medicine tube 107, which plays the role of upper and lower limit, and the installation of the medicine tube 107 is completed. When disassembling, the medicine tube 107 is pushed downward to make its top detach from the top of the placement groove 104, and then its top is tilted and moved out of the placement groove 104, and finally the medicine tube 107 is taken out, which is convenient for the staff to quickly disassemble and replace the medicine tube 107, saving time and effort, and high work efficiency.

[0035] Example 2, please refer to Figure 5 and Figure 6 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a sealing component 3 is provided at the bottom center position of the medicine tube 107, the sealing component 3 includes a docking nozzle 301 and a cylindrical groove 301a provided at the inner center position thereof, the inner top end of the cylindrical groove 301a is fixedly connected with sealing telescopic rods 302 at uniform intervals along the circumferential direction, and the telescopic end of the sealing telescopic rod 302 is installed with a sealing plate 304, which solves the problem that the storage structure of the existing multifunctional automatic pen-type injector lacks sealing measures when in use, so the storage cannot be sealed after it is disassembled separately, affecting the use.

[0036] Specifically, a sealing spring 303 is sleeved on the outer side of the outer wall of the sealing telescopic rod 302, and the sealing spring 303 is located between the inner wall of the cylindrical groove 301a and the upper surface of the sealing plate 304. A sealing ring 304a is bonded to the outer edge of the bottom of the sealing plate 304, and a movable ring 306 is provided in the gap below the docking nozzle 301. A connecting hard pipe 305 is fixedly connected to the inner wall of the movable ring 306. The top end of the connecting hard pipe 305 passes through the center position of the bottom of the cylindrical groove 301a and is connected to the center position of the lower surface of the sealing plate 304. Liquid outlet holes 305a are evenly spaced along the circumferential direction above the outer wall of the connecting hard pipe 305.

[0037] Furthermore, the cross-section of the cylindrical groove 301a is rectangular. The sealing telescopic rod 302 plays a role in limiting the sealing spring 303. Under the action of the elastic performance of the sealing spring 303, the sealing plate 304 can be driven to move. The sealing performance between the contact surfaces can be increased through the sealing ring 304a. The liquid medicine can flow out through the connecting rigid pipe 305 and the liquid outlet hole 305a.

[0038] The operation process of this embodiment is as follows: After the medicine tube 107 is installed inside the placement groove 104, the moving ring 306 below the docking nozzle 301 will contact and press against the inner wall of the docking groove 201a. The top of the moving ring 306 is connected to the bottom of the sealing plate 304 through the connecting rigid pipe 305. Therefore, when the moving ring 306 moves upward, it will push the sealing plate 304 to move upward under the action of the connecting rigid pipe 305. When the sealing plate 304 moves upward, it will squeeze the sealing telescopic rod 302 and the sealing spring 303 above it. At this time, the sealing plate 304 can be moved out of the inner bottom of the cylindrical groove 301a. At the same time, the liquid outlet hole 305a on the outer wall of the connecting rigid pipe 305 will enter the inside of the cylindrical groove 301a. Then, the liquid medicine inside the medicine tube 107 can be squeezed through the driving rod 108 and the sealing plug. The liquid medicine will be discharged from the syringe 103 through the cylindrical groove 301a, the liquid outlet hole 305a, the connecting rigid pipe 305, and the connecting hose 203. After the medicine tube 107 is taken out of the placement groove 104, under the action of the elastic performance of the sealing spring 303, the sealing plate 304 is pressed against the inner bottom end of the cylindrical groove 301a, and the sealing ring 304a can play a sealing role, thus avoiding the leakage of the liquid medicine during the storage of the medicine tube 107.
