Problems solved by technology

For some small medical device parts, it is not convenient to use a large testing instrument for testing, and it is impossible to clamp them with a large clamping instrument
Therefore, it often happens that the components under test are manually clamped by hand for detection. On the one hand, the labor intensity is high, and on the other hand, it will affect the accuracy of the detection, and may even cause work-related accidents.

Embodiment Construction

[0014] see figure 1 , the present invention below 0.4mm needle tube quick clamp, including coupling rod 1, locking body 2, two locking blocks 3 and locking cap 4.

[0015] The coupling rod 1 is composed of a rod seat 11 and a cylindrical rod body 12 connected on the rod seat, and the rod body is provided with an external thread for connecting with a locking body.

[0016] The locking body 2 is a cylindrical structural member, one end of which is provided with an internal thread to be threadedly connected with the rod body 12 of the coupling rod, and the other end is provided with an external thread and a tapered groove 21 for accommodating two locking blocks is provided at its front end , there is a small hole 22 that allows the measured needle tube to go deep into the bottom of the groove.

[0017] Two locking blocks 3 are two semi-cones, and the two semi-cones are combined to form a whole cone and are arranged in the tapered groove 21 at the front end of the locking body 2,...

Abstract

A needle tube rapid clamping apparatus comprises a coupling rod, a locking element, two locking blocks and a locking cap. The locking element is connected on the coupling rod, the two locking blocks are positioned inside a conical groove on the locking element, and the locking cap is connected with the locking element for clamping the two locking blocks. The application method of the invention comprises the following steps of: releasing the locking cap to relax the two locking blocks, inserting the detected needle tube from a needle hole on the locking cap and inserting into the space between the two locking blocks from the conical groove above the two locking blocks, and winding the locking cap to lock the two locking blocks, so as to clamp the detected needle tube. The invention solves the clamping difficult of the needle tube with diameter less than 0.4mm, and has the advantages of convenient, rapid and safe application, simple structure, easy production, low cost, and easiness for popularization.

Description

technical field [0001] The invention relates to a tooling device, in particular to a quick clamp for clamping a needle tube below 0.4 mm of a syringe to be tested when a ZWICK universal tension meter is used to test the pulling force of a combined syringe needle tube and a use method thereof. Background technique [0002] In the medical device industry, it is necessary to test the performance or quality of the produced medical devices. For some small medical device parts, it is not convenient to use a large testing instrument for testing, and it is impossible to clamp them with a large clamping instrument. Therefore, it often happens that the components under test are manually clamped by hand for testing. On the one hand, the labor intensity is high, on the other hand, it will affect the accuracy of the test, and may even cause work-related accidents. Therefore, it is necessary to design and manufacture a convenient, fast and safe small fixture to meet the detection needs o...
