Description

Technical Field

[0001] The utility model relates to the technical field of syringe production, in particular to a syringe rubber plug size measuring device. Background Art

[0002] As we all know, syringes are a common medical device. The emergence of syringes is an epoch-making revolution in the field of medical devices. The process of extracting and injecting gas or liquid with a needle is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod. The inside of the syringe needs to be kept airtight so that when the piston core rod is pulled, a negative pressure is formed in the syringe to suck the liquid medicine into the inside. In order to improve the sealing, a rubber plug is usually installed on the head of the piston core rod. The diameter of the rubber plug needs to be slightly larger than the syringe. After the syringe rubber plug is produced, in order to ensure that the size of the rubber plug is appropriate, it is necessary to conduct random inspections on the rubber plug. The existing measurement method is usually to directly use a measuring ruler for measurement, but this method requires picking up the rubber plugs and comparing them one by one during operation, which is more cumbersome. In view of the above problems, the present application designs a syringe rubber plug size measuring device. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , a syringe stopper size measuring device comprises a base 1, the base 1 is provided with an ejection mechanism for ejecting the stopper, the ejection mechanism comprises two containing grooves 2, the containing grooves 2 are fixedly connected to the base 1, a telescopic spring 3 is installed in the containing grooves 2, an ejection plate 4 is rotatably connected to the base 1, a lower pressure strip 5 is fixedly connected to the ejection plate 4, a limiting mechanism for pressing the lower pressure strip 5 is provided on the base 1, a measuring mechanism for measuring the size of the stopper is provided on the base 1, the limiting mechanism comprises two limiting boxes 6, the two limiting boxes 6 are fixedly connected to the base 1, a limiting frame 7 is slidably connected in the two limiting boxes 6, and a notch matching the size of the lower pressure strip 5 is opened on the limiting box 6.

[0022] The measuring mechanism includes a fixed plate 8, which is fixedly connected to the base 1. The base 1 is provided with two sliding grooves, in which sliders 9 are slidably connected. The top ends of the two sliders 9 are fixedly connected to a movable plate 10, and a measuring ruler 11 is fixedly connected to the movable plate 10. The measuring ruler 11 is slidably connected to the fixed plate 8. A accommodating box 12 is provided on the base 1. A drawer opening is provided at the front end of the base 1, and a storage drawer 13 is slidably provided in the drawer opening.

[0023] When the device is in use, first pull out the storage drawer 13 and place the rubber plug to be measured on the pop-up plate 4, pull the measuring ruler 11, the measuring ruler 11 drives the movable plate 10 to move forward, the movable plate 10 drives the slider 9 to slide in the slide groove, the movable plate 10 moves forward to clamp the rubber plug, and observes the scale on the measuring ruler 11. When the measurement is completed, pull the limit frame 7 to the left, the limit frame 7 slides to the left in the limit box 6, the telescopic spring 3 loses its limit extension, and the telescopic spring 3 pushes the pop-up plate 4 upward, and the pop-up plate 4 rotates on the base 1. The measured rubber plug on the pop-up plate 4 slides into the accommodating box 12 along the inclined pop-up plate 4. When it is necessary to measure again, press the lower pressure strip 5 to drive the pop-up plate 4 to rotate in the base 1. At this time, the pop-up plate 4 is horizontally pushed to the right by the limit frame 7, and the limit frame 7 slides in the limit box 6 to the lower pressure strip 5, and the rubber plug to be measured can be placed on the pop-up plate 4 and measured again;

[0024] When using this device, it was found that when operating the limit frame 7 and the storage drawer 13, it is difficult to operate by directly holding. In order to avoid the above problem, in this embodiment, the top of the limit frame 7 and the front end of the storage drawer 13 are fixedly connected with an operating handle 14, and the operating handle 14 is provided with anti-slip grooves.

[0025] It was found during use of the device that it needs to be operated horizontally. If the rubber plug on the device cannot be placed horizontally when the device is tilted, the measured data will have a certain error. In order to avoid the above problem, in this embodiment, a plurality of support pads 15 are fixedly connected to the bottom end of the base 1.
