Description

Technical Field

[0001] The utility model belongs to the technical field of fluid transportation, and in particular relates to a quick fixed-length pressing device for a connecting pipe of an injection pump. Background Art

[0002] The syringe pump uses a mechanical device to push the syringe to complete the liquid delivery. The liquid flows and is transported through the connecting tube. Under the pressure of the syringe pump, the connecting tube is easy to loosen from its fixed joint, resulting in the inability of the liquid to flow normally and leakage. In order to prevent this phenomenon from happening, the syringe pump connecting tube needs to be flanged to increase the contact area between the tube and the joint, and improve the stability and air tightness of the liquid flow during the operation of the syringe pump.

[0003] During the fixing process of the syringe pump connecting tube, it is easy for the reserved length of the syringe pump connecting tube port to be too long or too short. If it is too long, the risk of bending and deformation of the syringe pump connecting tube during operation will increase, while if it is too short, the effectiveness and quality of the port flanging will be limited, making it difficult to achieve an ideal flanging effect. Therefore, a quick fixed-length clamping device for syringe pump connecting tube is proposed. Utility Model Content

[0032] See also Figure 1-4The lifting mechanism 10 includes a cylinder 110, a lifting block 120, and a top block 130. There are two cylinders 110, which are mounted on both sides of the base 30. A slide rail 111 is mounted on the outer shell of the two cylinders 110 away from each other. There are two lifting blocks 120, which are slidably connected to the outer shells of the two cylinders 110 through the slide rail 111. The lifting blocks 120 are L-shaped, and the tops of the two lifting blocks 120 are mounted together on the bottom of the top block 130.

[0033] When in use, the two cylinders 110 synchronously drive the two lifting blocks 120 to rise or fall, and the two lifting blocks 120 drive the top block 130 to rise or fall.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The upper pressing mechanism 20 includes a connecting block 210, a resistance block 220 and an upper pressing block 230. The connecting block 210 is installed at the bottom of the top block 130. There are two resistance blocks 220. The two resistance blocks 220 are installed in front of the connecting block 210. A No. 1 groove 2101 is provided in the middle of the bottom end of the connecting block 210. The upper pressing block 230 is installed in the No. 1 groove 2101. A No. 2 groove 2301 is provided at the bottom of the upper pressing block 230, and a No. 3 groove 2302 is provided on the No. 2 groove 2301.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 Installation areas 301 are provided on both sides of the base 30, and two cylinders 110 are installed on the installation areas 301. A No. 4 groove 302 is provided on the top of the base 30, and a fixing block 310 is installed inside the No. 4 groove 302. A sliding groove 3101 is provided in front of the fixing block 310, and a No. 5 groove 3102 is provided on the top of the fixing block 310. A lower pressing block 320 is installed in the No. 5 groove 3102. A protrusion 3201 that matches the No. 2 groove 2301 at the bottom of the upper pressing block 230 is provided on the top of the lower pressing block 320, and a No. 6 groove 3202 is provided on the protrusion 3201. The No. 3 groove 2302 and the No. 6 groove 3202 can be spliced ​​into a cylindrical groove.

[0036] The upper pressing block 230 and the lower pressing block 320 are located on the same vertical straight line, so that when the upper pressing block 230 is pressed downward, it can engage with the lower pressing block 320 to press the injection pump connecting tube 40 tightly.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 6A limit piece 330 is slidingly arranged in the slide groove 3101, and an elastic piece 340 is connected to the bottom of the limit piece 330 and the bottom of the inner cavity of the fourth groove 302. After the elastic piece 340 is compressed, it provides power for the limit piece 330 to move upward; limit slots 3301 are arranged on both sides of the top of the limit piece 330, and a limit rod 311 is connected in the slide groove 3101. The limit slot 3301 and the limit rod 311 are on the same vertical line. The limit piece 330 cannot continue to move up through the limit slot 3301 and the limit rod 311, so that the limit piece 330 reaches a fixed height; a seventh groove 3302 is arranged on the limit piece 330, and a limit block 350 is installed in the seventh groove 3302.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The limit block 350 is in a convex shape, and a No. 8 groove 3501 is provided on the limit block 350, and a No. 9 groove 3502 is provided in the No. 8 groove 3501. The No. 8 groove 3501 is used to resist the port of the injection pump connecting tube 40. The injection pump connecting tube 40 is sleeved on the inner rod 410, and the No. 9 groove 3502 is wide at the top and narrow at the bottom to facilitate the end of the inner rod 410 to be inserted. The width value of the narrow area of ​​the No. 9 groove 3502 is less than the diameter value of the injection pump connecting tube 40. The inner rod 410 plays the role of limiting the injection pump connecting tube 40, avoiding the problem that the injection pump connecting tube 40 cannot be fixed due to the hollow interior and easy deformation during the subsequent flanging of the injection pump connecting tube 40, and at the same time, it is convenient for the subsequent flanging machine to quickly locate the port of the injection pump connecting tube 40 for flanging.

[0039] The working principle and use process of the utility model are as follows: (1) Placement: The interior of the injection pump connecting tube 40 passes through the inner rod 410, and the tube wall of the injection pump connecting tube 40 is placed in the sixth groove 3202. The end of the injection pump connecting tube 40 contacts the eighth groove 3501, and one end of the inner rod 410 is placed in the ninth groove 3502, so that the part of the end of the injection pump connecting tube 40 leaking from the sixth groove 3202 each time is a fixed value.

[0040] (2) Fixing: Start the cylinder 110, the piston rod of the cylinder 110 pushes the lifting block 120 to move downward, the lifting block 120 drives the top block 130 to move downward, the top block 130 drives the resistance block 220 and the upper pressure block 230 to move downward through the connecting block 210; during the downward movement of the resistance block 220, the resistance limiter 330 moves downward, and the limiter 330 moves downward to squeeze the elastic member 340, such as Figure 3 As shown, when the limit member 330 moves downward, it will drive the limit block 350 to move downward, so that the injection pump connecting tube 40 and the inner rod 410 are moved out of the eighth groove 3501 and the ninth groove 3502, avoiding the obstruction of the limit member 330 when flanging.

[0041] (3) Removal: After the flanging is completed, the cylinder 110 is started, and the piston rod of the cylinder 110 pushes the lifting block 120 to move upward, so that the resistance block 220 moves upward accordingly, and the limit member 330 moves upward under the action of the elastic member 340 until the upper limit groove 3301 of the limit member 330 is blocked by the limit rod 311 so that it cannot move upward, thereby allowing the limit member 330 to return to its original height again and wait for the next use.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
