Problems solved by technology

Existing detection operations mostly use vernier calipers, but due to the obstruction of the measuring end of the caliper by the needle seat, the vernier caliper cannot touch the needle head, but can only measure parallel to the head. Therefore, the accuracy of measurement depends on the parallelism determined by the operator, and subjective factors are more influential. Large, poor data repeatability, and low detection efficiency

Embodiment Construction

[0015] like figure 1 As shown, the special gauge for injection needles includes a cylinder 1, a number of card slots 2 and a scale slot 3. The clamping slot 2 is used to clamp injection needles of one or several specifications, and the scale slot 3 is used to detect whether the length of the injection needle of a specific specification meets the testing requirements.

[0016] The cylinder 1 is cylindrical, and the slots 2 are arranged parallel and vertically along the surface of the cylinder 1 . The outer wall of the cylinder 1 is integrated with a plurality of the card slots 2, which can be used for length detection of injection needles of various specifications. By rotating the cylinder 1, the corresponding engaging slot 2 can be selected for detecting injection needles of corresponding specifications.

[0017] The bottom surface 11 of the cylinder 1 is perpendicular to the outer surface of the cylinder 1, and each of the clamping grooves 2 is perpendicular to the end surf...

Abstract

A gauge specialized for an injection needle has a cylindrical structure. The gauge is provided with a plurality of snapping troughs which are vertically arranged and are parallel with one another on the external surface of the cylinder body. The snapping trough are provided with a plurality of scale troughs which are horizontally arranged and are parallel with one another. According to the gauge,the vertical snapping troughs arranged on the cylinder body are utilized so that a needle seat is snapped outside the snapping troughs and the needle head is snapped in the snapping troughs. Furthermore a measuring range is determined according to the upper side and the lower side of the scale trough which is arranged on the snapping trough, thereby replacing number reading by a visual observing manner, simplifying steps in measuring operation, reducing measuring operation difficulty and improving measuring efficiency and measuring accuracy.

Description

technical field [0001] The invention relates to the technical field of injection needle quality detection, in particular to a special gauge for injection needles. Background technique [0002] Before the syringe needle is put into the next process for assembly and production, its length and other indicators need to be tested. Existing detection operations mostly use vernier calipers, but due to the obstruction of the measuring end of the caliper by the needle seat, the vernier caliper cannot touch the needle head, but can only measure parallel to the head. Therefore, the accuracy of measurement depends on the parallelism determined by the operator, and subjective factors are more influential. Large, poor data repeatability, and low detection efficiency. Contents of the invention [0003] The invention provides a special gauge for injection needles to solve the above-mentioned deficiencies in the prior art. The vertical card slot arranged on the cylinder is used to make t...
