Automatic delivery device with self-locking mechanism

Abstract

The invention discloses an automatic delivery device with a self-locking mechanism. The automatic delivery device comprises a locking rail and a counterweight component (2) arranged in the middle of the locking rail, and a plurality of articles (5) to be taken are arranged below the counterweight component (2); when the article (5) to be taken located at the lowermost position is drawn away, the counterweight component (2) moves downwards along the locking rail under the action of the gravity and pushes the articles (5) which are not taken out to move downwards; and the two sides of the counterweight component (2) in the movement direction are each provided with at least one self-locking piece (4) which is matched with the locking rail to prevent the counterweight component (2) from moving in the contrary direction. The automatic delivery device with the self-locking mechanism is simple in structure and stable and convenient to operate.

Description

technical field [0001] The invention relates to the field of feeding devices, in particular to an automatic delivery device with a self-locking mechanism. Background technique [0002] With the advancement of in vitro diagnostic technology, based on a comprehensive terminal inspection equipment, many inspection items that should have been operated by professional inspectors in large hospitals or laboratories have gradually been simplified. Streamlined operation by highly trained personnel. This kind of testing equipment generally has the advantages of high-volume and high-efficiency testing. One of the important parts is that it is necessary to place a large amount of test paper or reagents in the equipment. The test paper can be operated by the internal mechanism of the equipment to react with the collected samples to obtain the test structure. There are a large number of test papers to ensure that after one filling, the test equipment can carry out dozens of sample tests...

Problems solved by technology

[0003] The test paper box used in the prior art includes a test paper box with a cavity, several test paper sheets arranged in the test paper box and a push rod arranged at one end of the test paper box, and the push rod exerts force on the test paper sheets during use. , Push the test paper sheet out from the other end of the test paper box for testing purposes. The test paper box with this structure has the following disadvantages: (1) It is necessary to add related electrical control equipment to the terminal inspection equipment, and increase related mechanism operation equipment , so as to increase the manufacturing cost; (2) because of the existence of the push rod, it is difficult to reduce the size of the terminal inspection equipment, which takes up more space in the inspection room; (3) when it is necessary to replace the test strips carrying other detection reagents, The push rod needs to be returned. Once the test paper box is placed flat or upside down, or even dropped unintentionally, the remaining dozens of test paper pieces inside will be tilted and turned over, or even fall out, making it unusable
