[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Example 1, as Figure 1 and Figure 2As shown, the leak detection device for eye drop bottles includes a placement box 1, and five clamping assemblies 2 are fixedly installed in a linear array on the bottom wall of the placement box 1. The five clamping assemblies 2 can be used to clamp eye drop bottles of different bottle sizes, and the bottle to be tested is always kept in the center position, which is convenient for subsequent testing. At the same time, with the assistance of the observation window 7, it is convenient to observe the testing process in real time, thereby improving the testing efficiency.

[0026] The rear end of the placement box 1 is slidably connected to a slide plate 3, and the upper end of the slide plate 3 is slidably mounted with an air injection assembly 4. The air injection assembly 4 can cooperate with the five clamping assemblies 2, so that after the five clamping assemblies 2 clamp the bottle to be inspected, the air injection assembly 4 can be accurately aligned with the bottle mouth, thereby facilitating subsequent inspection work. In addition, the air injection assembly 4 can also perform adaptive clamping according to the different diameters of the bottle mouth, thereby improving the versatility of the device.

[0027] An air bag 5 is fixedly connected to the upper portion of the outer surface of the gas injection component 4 , a mounting groove 6 is opened in the middle of the front end of the placement box 1 , and an observation window 7 is fixedly connected to the inner surface of the mounting groove 6 .

[0028] Embodiment 2: Based on embodiment 1, this embodiment is for achieving the purpose of clamping bottles of different sizes.

[0029] For details, see Figure 1 、 Figure 4 and Figure 5 , the five clamping components 2 each include two fixing rods 21 that are symmetrically distributed front to back. The front end of the fixing rod 21 on the front side is fixedly connected to the rear side wall of the inner surface of the placement box 1, and the rear end of the fixing rod 21 on the rear side is fixedly connected to the front end of the observation window 7. The ends of the two fixing rods 21 close to each other are each provided with a cylindrical groove 22. The inner surfaces of the two cylindrical grooves 22 are slidably connected to a guide rod 23. The outer surfaces of the two guide rods 23 are slidably connected to an elliptical plate 24. The lower end of the elliptical plate 24 is fixedly connected to the bottom wall of the placement box 1. The left and right ends of the elliptical plate 24 are linearly arrayed with a plurality of limiting holes 25. The limiting holes 25 on the same side are arranged in a plurality of positions. The surfaces are all slidably connected with guide rods 26, and the ends of several guide rods 26 on the left and several guide rods 26 on the right that are close to each other are fixedly connected with a clamping plate 28. The left side wall and the right side wall of the inner surface of the elliptical plate 24 are respectively fixedly connected with a plurality of springs 27 in a linear array at the ends close to the clamping plate 28 on the same side. The plurality of springs 27 on the same side are located outside the plurality of guide rods 26 on the same side. The ends of the two guide rods 23 that are close to each other are fixedly connected with a clamping plate 29, and the side of the clamping plate 29 on the same side that is close to the inner surface of the elliptical plate 24 is fixedly connected with a spring 20.

[0030] Furthermore, a plurality of air outlet slots 281 are formed in a linear array on the ends of the two clamping plates 28 on the same side that are close to each other.

[0031] Furthermore, the upper ends of the two clamping plates 29 on the same side and the upper ends of the two clamping plates 1 28 on the same side are both set at an oblique angle.

[0032] As can be seen from the above, the upper ends of the two clamping plates 29 and the two clamping plates 1 28 on the same side are set at an oblique angle. Therefore, when the lower end of the bottle body is placed into the cavity formed by the two clamping plates 29 and the two clamping plates 1 28 on the same side, the lower end of the bottle body will squeeze the two clamping plates 1 28 and the two clamping plates 2 29 on the same side outward. Under the action of the two springs 20 and the plurality of springs 1 27 on the same side, the two clamping plates 29 and the two clamping plates 1 28 can always fit on the four sides of the bottle body and keep the bottle body in the middle position. The plurality of limiting holes 25 on the same side cooperate with the plurality of guide rods 2 26 on the same side to play a role in limiting and guiding the two clamping plates 1 28, and the cylindrical groove 22 and the guide rod 1 23 on the same side cooperate with each other to play the same limiting and guiding role as mentioned above.

[0033] After the bottle body is clamped, water can be poured into the inner cavity of the placement box 1 until the water level is slightly lower than the bottle mouth.

[0034] The entire structural surface of the clamping assembly 2 mentioned above is sprayed with an anti-rust coating. This coating is a conventional setting in the prior art and only needs to meet the anti-rust effect and can increase the service life of the device. Therefore, this solution will not explain it in detail.

[0035] Embodiment 3: Based on embodiment 2, this embodiment is for achieving the purpose of performing airtightness detection on the bottle body after clamping.

[0036] For details, see Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The gas injection assembly 4 includes a parallel plate 41 slidably connected to the upper end of the slide 3, five gas injection holes 42 are opened in a linear array in the middle of the upper end of the parallel plate 41, a baffle 43 is fixedly connected to the front end of the parallel plate 41, five rectangular openings 44 are opened in a linear array at the upper end of the slide 3, and five clamping assemblies 45 are fixedly installed in a linear array at the lower end of the parallel plate 41. The output ends of the airbag 5 are all connected to the five gas injection holes 42.

[0037] Furthermore, the clamping assembly 45 includes five air injection tubes 451 fixedly connected in a linear array at the lower end of the parallel plate 41, and the upper ends of the five air injection tubes 451 are provided with air inlet holes 452 running through the lower ends thereof. A number of arc-shaped clamps 453 are fixedly connected in a circular array at the lower edges of the inner surfaces of the five air inlet holes 452, and the several arc-shaped clamps 453 fit together, and the five air inlet holes 452 are respectively connected to the five air injection holes 42.

[0038] Furthermore, a plurality of air outlet slots 281 are formed in a linear array on the ends of the two clamping plates 28 on the same side that are close to each other.

[0039] Furthermore, the observation window 7 is made of a transparent material.

[0040] As can be seen from the above, the five air inlet holes 452 are respectively connected to the five air injection holes 42, and the five air injection holes 42 are opened in the middle of the upper end of the parallel plate 41. Therefore, when the parallel plate 41 is pushed backward until the rear end of the baffle 43 is in contact with the front end of the slide plate 3, the five air injection tubes 451 will pass through the corresponding rectangular openings 44, and the five rectangular openings 44 all pass through the upper end of the slide plate 3. Therefore, the five air injection tubes 451 can pass through the corresponding rectangular openings 44 and then move to the upper side of the clamped bottle body and align with the bottle mouth. At this time, it is only necessary to slide the slide plate 3 downward so that the slide plate 3 drives the lower end of the parallel plate 41 to stick to the upper end of the placement box 1, thereby making the several arc-shaped clamping plates 453 on the same side wrap the bottle mouth on the same side, and the upper ends of the several arc-shaped clamping plates 453 can be stretched outward to different degrees according to the different widths of the bottle mouth.

[0041] When the arc-shaped clamping plates 453 on the same side are clamped at the bottle mouth on the same side, as described above, the output ends of the airbag 5 are all connected to the five gas injection holes 42. Therefore, by pressing the airbag 5, gas can be injected into the five gas injection holes 42, and the gas can be transmitted from the five gas injection holes 42 into the corresponding gas inlet holes 452 and then into the corresponding bottle body;

[0042] As can be seen from the above, the ends of the two clamping plates 28 on the same side that are close to each other are each provided with a plurality of air outlet grooves 281 in a linear array, and the observation window 7 is made of a transparent material. Therefore, when air is injected into the corresponding bottle body, if the bottle body is damaged or has a hole, the plurality of air outlet grooves 281 will not prevent the bubbles from floating upward normally in the water. The operator can then observe the position of the bubbles in the water in the inner cavity of the placement box 1 through the observation window 7, thereby determining the position of the bottle body in the bubbling state and then removing it.

[0043] When the bottle needs to be taken out after testing, it is only necessary to repeat the above operation in reverse, so this solution will not be described in detail.

[0044] The observation window 7 is made of a transparent material in the prior art, and is only required to be used for observing the interior of the placement box 1. The specific material can be adjusted according to actual production needs, so this solution will not be elaborated in detail.

[0045] The airbag 5 mentioned above is a conventional setting in the prior art. It only needs to be connected to the five air injection holes 42 during air injection. Its specific shape and installation method can be adjusted according to actual production needs, so this solution will not elaborate on it in detail.

[0046] This solution uses the clamping component 2, the gas injection component 4 and the clamping component 45 to cooperate with each other, making the operation of the device more convenient and quick, and can quickly identify tiny leaks, thereby screening out unqualified products, thereby ensuring the safety and effectiveness of the products and ensuring the safety of consumers' medication.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
