It is very likely that the components will be damaged by pinching due to excessive force, reducing the convenience and operability of the device. Summary of the Utility Model

Detailed implementation manner
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0024] Refer to Figures 1-6 , an encapsulation device for potassium magnesium aspartate injection, including an encapsulation bottle body 1 and a bottle cap 2. A support plate is fixedly installed on the encapsulation bottle body 1. An air hole is opened at the upper end of the bottle cap 2. Air pumps 3 are symmetrically and fixedly installed on the bottle cap 2. The air pumps 3 are communicated with the air hole through a connecting pipe 4. A push plate 5 is hermetically slidably installed in the air pump 3. A vertical rod 6 is vertically fixedly installed at the lower end of the push plate 5. A locking component for locking the vertical rod 6 is provided on the support plate. A push rod 7 is vertically fixedly installed on the upper surface of the push plate 5. One end of the push rod 7 passes through the air pump 3. A first telescopic spring 8 is sleeved on the push rod 7. The two ends of the first telescopic spring 8 are respectively fixedly connected to the push plate 5 and the air pump 3. A strip-shaped rod 18 is fixedly installed at the upper ends of the two push rods 7. A rubber sleeve is sleeved on the strip-shaped rod 18.
[0025] When encapsulating the injection solution, add the injection solution into the encapsulation bottle body 1, then cover the bottle cap 2 on the encapsulation bottle body 1. Drive the two push rods 7 to move vertically downward through the strip-shaped rod 18, thereby driving the push plate 5 to move vertically downward in the air pump 3. At this time, the space between the upper part of the push plate 5 and the air pump 3 becomes larger. The air in the encapsulation bottle body 1 can be sucked into the air pump 3 through the connecting pipe 4. As the air in the encapsulation bottle body 1 decreases and the air pressure decreases, under the action of the pressure, the bottle cap 2 will be firmly adsorbed on the encapsulation bottle body 1. During the vertical downward movement of the push plate 5, the vertical rod 6 will be driven to move downward, and then the vertical rod 6 is locked by the locking component, thereby preventing the push plate 5 from moving back in the air pump 3 and ensuring that the bottle cap 2 is tightly sealed on the encapsulation bottle body 1.
[0026] A jack is opened at the lower end of the vertical rod 6. The locking component includes a moving rod 10 horizontally slidably installed on the support plate through a mounting block 9, a trapezoidal block 11 fixedly installed at one end of the moving rod 10, and a second telescopic spring 12 sleeved on the moving rod 10. The inclined surface of the trapezoidal block 11 faces upward. The two ends of the second telescopic spring 12 are respectively fixedly connected to the mounting block 9 and the trapezoidal block 11. A pulling block 13 is fixedly installed at the end of the moving rod 10 away from the trapezoidal block 11. A rectangular hole is opened on the pulling block 13.
[0027] During the vertical downward movement of the vertical rod 6, it will contact the inclined surface of the trapezoidal block 11, thereby driving the moving rod 10 to move to one side, and the second telescopic spring 12 is compressed. Until one end of the trapezoidal block 11 is aligned with the jack formed on the vertical rod 6, under the action of the elastic force of the second telescopic spring 12, one end of the trapezoidal block 11 will be inserted into the jack, thus restricting the upward movement of the vertical rod 6.
[0028] When it is necessary to open the encapsulated bottle body 1, the moving rod 10 is pulled through the pull block 13 to remove the trapezoidal block 11 from the jack. Then, under the action of the elastic force of the first telescopic spring 8, the push plate 5 drives the vertical rod 6 to move vertically upward. At the same time, the air in the air cylinder 3 enters the encapsulated bottle body 1 through the connecting pipe 4. At this time, the air pressure in the encapsulated bottle body 1 returns to normal, and the bottle cap 2 can be separated from the encapsulated bottle body 1, which is convenient and simple to use, and increases the convenience and operability of the staff's effort.
[0029] A sliding rod 14 is vertically and fixedly installed on the lower surface of the bottle cap 2. A floating plate 15 is slidably sleeved on the sliding rod 14. The density of the floating plate 15 is less than the density of the injection solution. When the injection solution is added to the encapsulated bottle body 1, the floating plate 15 will move upward with the liquid level of the injection solution and thus float on the liquid surface of the injection solution. The presence of the floating plate 15 can reduce the shaking of the injection solution in the encapsulated bottle body 1 and prevent the injection solution from shaking violently, which affects the use effect of the injection solution.
[0030] A first sealing ring 16 is inclined and fixedly installed near the bottle mouth of the encapsulated bottle body 1. The first sealing ring 16 is inclined upward. A second sealing ring 17 is inclined and fixedly installed on the lower surface of the bottle cap 2. The second sealing ring 17 is inclined downward. When the bottle cap 2 is covered on the upper end of the encapsulated bottle body 1, the first sealing ring 16 contacts the second sealing ring 17. Under the action of the first sealing ring 16 and the second sealing ring 17, the airtightness between the bottle cap 2 and the encapsulated bottle body 1 can be effectively improved.
[0031] In the present utility model, when it is necessary to open the encapsulated bottle body 1, the locking of the vertical rod 6 by the locking component is released. Then, under the action of the elastic force of the first telescopic spring 8, the push plate 5 drives the vertical rod 6 to move vertically upward. At the same time, the air in the air cylinder 3 enters the encapsulated bottle body 1 through the connecting pipe 4. At this time, the air pressure in the encapsulated bottle body 1 returns to normal, and the bottle cap 2 can be separated from the encapsulated bottle body 1, which is convenient and simple to use, and increases the convenience and operability of the staff's effort.
[0032] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
