Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a syringe plug tightening device. Background Art

[0002] Screw-cap syringes are widely used in hospitals, clinics, medical aesthetics and other places. The front end of the screw-cap syringe, that is, around the liquid outlet tube at the front end of the screw-cap syringe, is surrounded by a circle of screw-cap parts with internal threads, which can be spirally connected to the plug through the screw-cap part. During use, since the plug is usually installed on the syringe by manual tightening, the tightening operation of the plug is relatively laborious, and the tightening torque applied to the plug cannot be accurately controlled, resulting in difficulty in ensuring the tightening degree of the plug, affecting the installation stability of the plug on the syringe. In view of this, we propose a syringe plug tightening device to solve the above problems. Utility Model Content

[0019] like Figures 1 to 4 As shown, the utility model provides a syringe plug tightening device, including a shell 1, the interior of the shell 1 is rotatably connected to a rotating shaft 102 through a bearing seat 101, the upper end of the rotating shaft 102 is fixedly connected to a tightening seat 2 through a connecting column 103, the inner bottom end of the tightening seat 2 is fixedly installed with an infrared sensor 201, the inner side wall of the tightening seat 2 is fixedly installed with a plurality of plug twist blocks 202 at intervals, and a handheld syringe is inserted into each plug twist block 202 in the tightening seat 2. A through opening 3 is opened on the surface of the shell 1 above the plug twist block 202, and a micro electric push rod 4 is fixedly installed inside the shell 1. 4 is fixedly connected to a transmission seat 5, and a pressure sensor 501 is fixedly installed at the end of the transmission seat 5. A sleeve rod 502 is installed at the force-bearing end of the pressure sensor 501. A T-shaped column 6 is slidably sleeved on the sleeve rod 502. A spring 7 is fixedly connected between the sleeve rod 502 and the T-shaped column 6. A rack 601 is fixedly installed at one end of the T-shaped column 6. A gear ring 104 is fixedly sleeved on the outside of the rotating shaft 102. The rack 601 is engaged with the gear ring 104. The transmission seat 5 is driven to move by the micro-electric push rod 4. The rack 601 can drive the rotating shaft 102 and the tightening seat 2 to rotate, so that the tightening seat 2 tightens the plug on the syringe.

[0020] Among them, such as Figure 1 and Figure 4 As shown, a controller 8 is fixedly mounted on the shell 1, and a display screen 801 is fixedly mounted on the outside of the controller 8. The output ends of the infrared sensor 201 and the pressure sensor 501 are electrically connected to the input end of the controller 8, and the output end of the controller 8 is electrically connected to the input end of the micro electric push rod 4 and the display screen 801. If the plug on the syringe is inserted into each plug twist block 202 in the tightening seat 2, the infrared sensor 201 can be used to identify and sense the plug on the syringe. The controller 8 controls the micro electric push rod 4 to drive the transmission seat 5 to move according to the identification and sensing information. When the plug is tightened on the syringe, the spring 7 is gradually contracted under the force, and the pressure sensor 501 monitors the tightening torque information of the plug in real time, and the tightening torque information of the plug can be displayed through the display screen 801.

[0021] Among them, such as Figure 1 and Figure 4 As shown, a warning light 9 is fixedly installed on one side of the housing 1 near the controller 8. The output end of the controller 8 is electrically connected to the input end of the warning light 9. If the tightening torque applied to the plug reaches a set value, the controller 8 controls the micro electric push rod 4 to stop driving the transmission seat 5 to move, thereby ending the tightening operation of the plug on the syringe. The warning light 9 emits a light signal for prompting, so as to quickly determine that the tightening operation of the plug on the syringe is completed.

[0022] Among them, such as Figure 3 As shown, a guide seat 105 is fixedly installed at the inner bottom end of the shell 1, and the guide seat 105 is slidably sleeved on the outside of the transmission seat 5, thereby achieving the purpose of providing a good guide for the transmission seat 5 when it moves.

[0023] Among them, such as Figure 2 As shown, there are four plug twist blocks 202 , and the four plug twist blocks 202 are arranged in a circular shape with equal intervals.

[0024] Among them, such as Figure 2 As shown, a protective sealing ring 301 is fixedly installed on the inner side of the through-hole 3. The inner diameter of the protective sealing ring 301 is the same as the diameter of the tightening seat 2, so as to prevent the gap between the tightening seat 2 and the through-hole 3 from easily infiltrating impurities.

[0025] The working principle of this utility model:

[0026] During use, the handheld syringe is inserted with its plug onto each plug twist block 202 in the tightening seat 2. The infrared sensor 201 can be used to identify and sense the plug on the syringe. The controller 8 controls the micro electric push rod 4 to drive the transmission seat 5 to move, and the rack 601 can be used to drive the rotating shaft 102 and the tightening seat 2 to rotate. During the tightening process of the plug on the syringe, the spring 7 is gradually contracted by the force, and the pressure sensor 501 monitors the tightening torque information of the plug in real time. If the tightening torque of the plug reaches the set value, the controller 8 controls the micro electric push rod 4 to stop driving the transmission seat 5 to move, thereby ending the tightening operation of the plug on the syringe, and the prompt light 9 emits a light signal to prompt. After the tightened plug on the syringe is taken out from the tightening seat 2, the controller 8 controls the micro electric push rod 4 to drive the transmission seat 5 to reset, so that the tightening seat 2, the rack 601 and the spring 7 are restored to their initial state and can be used for the next tightening operation.
