DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Embodiment 1: This embodiment aims to solve the problem that when most testers test drugs, the drug needs to be placed in a sealed test chamber 112 and the test chamber 112 is vacuumed. However, there may be a gap between the existing test tube 111 and the tube cover 114, which may lead to unsatisfactory detection results. Figure 1-Figure 5 A pharmaceutical production seal tester includes a tester body 110 and a test cylinder 111. The test cylinder 111 is mounted on the tester body 110. A test cavity 112 for placing medicine is defined within the test cylinder 111. A material inlet 113 is provided on the test cylinder 111. A cylinder cover 114 is mounted on the test cylinder 111. A rod 115 is mounted at the bottom of the cylinder cover 114. A slot 116 corresponding to the rod 115 is defined on the test cylinder 111. The rod 115 is plugged into the slot 116. A sealing block 117 for sealing the material inlet 113 is mounted within the cylinder cover 114. An air inlet 119-118 is defined on the tester body 110. A test head 133 is mounted within the test cavity 112. An air hole 120 is defined within the test head 133. An air pipe 121 is connected between the air hole 120 and the air inlet 119-118.

[0025] A first bevel block 122 and a second bevel block 123 are disposed within slot 116. These blocks are symmetrically arranged and form an interference fit with the insertion rod 115. The first bevel block 122, the second bevel block 123, and the sealing block 117 are all rubber blocks. A socket 124 corresponding to the feed port 113 is defined within the sealing block 117, and the feed port 113 is inserted into the socket 124. A positioning ball 125 is mounted on the outside of the feed port 113. A positioning groove 126 corresponding to the positioning ball 125 is defined within the sealing block 117. The positioning groove 126 communicates with the socket 124, and the positioning ball 125 engages with the positioning groove 126.

[0026] Before starting the test, ensure that the tester body 110 and the test cylinder 111 are in the correct position and state. The cylinder cover 114 is opened, the feed port 113 is exposed, and the medicine is ready to be placed. Put the medicine into the test cavity 112 through the feed port 113. Lower the cylinder cover 114 and insert the insertion rod 115 into the slot 116 of the test cylinder 111. Ensure that the insertion rod 115 fits tightly with the first bevel block 122 and the second bevel block 123 to achieve a tight connection. The socket 124 of the sealing block 117 is aligned with the feed port 113, and the positioning ball 125 is snapped into the positioning groove 126 to ensure that the sealing block 117 is correctly in place. Introduce gas into the air hole 120 of the test head 133 through the air inlet 119118. Use the air pipe 121 to connect the air inlet 119118 and the air hole 120 to form a closed test circuit. The tester body 110 monitors the air pressure changes to determine the sealing performance of the test cavity 112. Based on the air pressure change data, the sealing of the drug packaging is evaluated. If a leak is detected, the relevant data is recorded and further analyzed.

[0027] In this embodiment: by providing a symmetrical first inclined block 122 and a second inclined block 123, an interference fit between the insertion rod 115 and the slot 116 is ensured, so that a tight connection between the tube cover 114 and the test tube 111 is achieved, thereby eliminating the traditional gap problem and significantly improving the sealing performance. The rubber sealing block 117 at the bottom of the tube cover 114 provides an additional sealing layer to prevent gas from leaking from the feed port 113. The elasticity of the rubber material enhances the sealing effect and ensures the airtightness of the test chamber 112. The snap-fit ​​design of the positioning ball 125 and the positioning groove 126 ensures that the feed port 113 is accurately inserted into the socket 124 of the sealing block 117, further enhancing the sealing effect, thereby reducing operational errors and improving the reliability of the seal.

[0028] Example 2: This example aims to solve the problem that the drug is not easy to be pushed out of the test tube 111 after the test is completed. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-Figure 5 . A placement seat 127 for placing medicines is installed in the test cavity 112, and a placement groove 128 is provided in the placement seat 127. A spring 129 is placed at the bottom of the placement seat 127, and one end of the spring 129 is in contact with the bottom of the placement seat 127, and the other end of the spring 129 is in contact with the inner wall of the test cavity 112. Sliders 130 are installed on both sides of the placement seat 127, and a slide groove 131 corresponding to the slider 130 is provided in the test cavity 112. The slide groove 131 is connected to the test cavity 112, and the slider 130 is slidably plugged into the slide groove 131. A control panel 132 is installed on the top of the cylinder cover 114 for easy control. After the inspection is completed, the cylinder cover 114 is opened. Due to the action of the spring 129, the placement seat 127 will be pushed upward, and the medicine will pop out of the placement groove 128. The design of the slider 130 and the slide groove 131 ensures the smooth movement of the placement seat 127 in the test cavity 112, which is convenient for the operator to take out the medicine.

[0029] In this embodiment: the setting of the spring 129 allows the placement seat 127 to be pushed upward after the test is completed, and the medicine pops out from the placement groove 128, which reduces the operator's manual removal steps and improves the convenience of removal. At the same time, it ensures a gentle push when the medicine is taken out, reduces the impact on the medicine, and reduces the risk of damage. The sliding connection between the slider 130 and the slide groove 131 ensures the smooth movement of the placement seat 127 in the test cavity 112, reduces the possibility of friction and jamming, and enables the placement seat 127 to move upward smoothly under the action of the spring 129, further improving the convenience of medicine removal.
