Abstract
Description
Technical Field

[0002] At present, in the medical field, when testing some medical solutions such as protein solutions, an optical detection device is used to emit light such as laser to irradiate the solution for detection. The optical detection device generally includes a laser, a base and a photoelectric sensor. The laser emitted by the laser passes through the hole on the base and irradiates the solution and is received by the photoelectric sensor. The solution is detected using nephelometry. The nephelometry is that the photoelectric sensor receives the light scattered by the solution particles at a certain angle to the incident light, so there is a certain angle between the normal direction of the photoelectric sensor and the propagation direction of the light. And the angle tolerance must be strictly controlled, otherwise it will cause the light signal received by the photoelectric sensor to be different in size, resulting in large errors in the tests between different instruments.
[0003] At present, there is a lack of tools to measure the angle between two holes in the base. The common method is to use a two-dimensional imager to project and measure the parts. However, the two-dimensional imager is expensive and requires a large space to place the instrument. Secondly, there are certain requirements for instrument operation, and professional engineers are required to manage and operate it, which is not conducive to production and processing inspection.

The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0029] like Figure 1-3 As shown, in an embodiment of an angle detection mechanism, the angle detection mechanism is used to detect a base 1 in an optical detection device, the base 1 includes a non-continuous first hole 11 and a second hole 12, and a placement groove 13 connected to both the first hole 11 and the second hole 12, the angle detection mechanism includes a first detection member 2, one side of the first detection member 2 is provided with a protrusion 21 matching the shape of the first hole 11, and the other side is provided with a groove 22, the first detection member 2 is used to extend into the placement groove 13 and make the protrusion 21 extend into the first hole 11, so as to detect the angle between the first hole 11 and the second hole 12.
[0030] In this embodiment, the first detection member 2 can be matched with the first hole 11 through the protrusion 21, so that when the protrusion 21 extends into the first hole 11, the staff can observe through the second hole 12 whether the groove 22 can be seen, or pass a rod or other member through the second hole 12 to see whether it can extend into the groove 22 to determine whether the angle between the first hole 11 and the second hole 12 on the base 1 meets the requirements, thereby solving the current technical problem of lack of angle detection of the base 1 of the optical detection device.
[0031] In addition, the staff can also test the base 1 by inserting a finger through the second hole 12 to see whether the finger can be inserted into the groove 22 .
[0032] It can be understood that when the base 1 is a qualified product, the groove 22 is located in the extension direction of the second hole 12 .
[0033] In an embodiment of the angle detection mechanism, the extension length of the side wall of the protrusion 21 is smaller than the extension length of the side wall of the groove 22 .
[0034] In the present embodiment, it can be understood that the formation of the protrusion 21 increases the overall volume of the first detection member 2. During the detection process, the first detection member 2 at least partially needs to be inserted into the placement groove 13. In order to facilitate the insertion of the first detection member 2, the size of the protrusion 21 should not be too large. On the other hand, the large depth of the groove 22 can facilitate docking, and the deepening of the groove is more conducive to observation and detection of whether it is qualified, which has the effect of amplifying the error.
[0035] In an embodiment of the angle detection mechanism, the extension direction of the side wall of the protrusion 21 and the extension direction of the side wall of the groove 22 are arranged at an angle.
[0036] In this embodiment, by setting the angle, it can be used to detect at a specific angle and utilize turbidimetry to detect the solution. Turbidimetry is a method in which a photoelectric sensor receives light scattered from solution particles at a certain angle to the incident light. Therefore, there is a certain angle between the normal direction of the photoelectric sensor and the propagation direction of light. The size of the angle is the angle between the extension direction of the side wall of the protrusion 21 and the extension direction of the side wall of the groove 22.
[0037] In an embodiment of the angle detection mechanism, the protrusion 21 and the groove 22 are located at the same end of the first detection member 2. In this embodiment, specifically, the first detection member 2 can be a block-shaped structural member such as a cuboid or a cube, which is divided into an upper end and a lower end with the middle as a boundary. By arranging the protrusion 21 and the groove 22 at the same end, preferably the upper end, the protrusion 21 can be inserted after the bottom of the first detection member 2 contacts the bottom of the placement groove 13, thereby improving stability. Moreover, since they are located on the same side, when the rod-shaft structure extends into the groove 22, the protrusion 21 can be tightly extended into the first hole 11, and when the groove 22 is located at the lower end, the rod-shaft structure extends into the groove 22, which easily causes the protrusion 21 to be separated from the first hole 11.
[0038] Specifically, the protrusion 21 and the first hole 11 are in transition fit.
[0039] In an embodiment of the angle detection mechanism, the surface of one side of the first detection member 2 where the protrusion 21 is provided is a plane.
[0040] In this embodiment, the plane is arranged to be easily fitted with the side wall of the placement groove 13. After the protrusion 21 extends into the first hole 11, the staff can push the first detection member 2 to make the plane fit onto the side wall of the placement groove 13, which is beneficial to improve the positioning accuracy.
[0041] In an embodiment of the angle detection mechanism, the angle detection mechanism further includes a second detection member 3 , which matches the shape of the second hole 12 and can be passed through the second hole 12 , and has a detection end 31 that matches the shape of the inner wall of the groove 22 .
[0042] In combination with the previous embodiments, the second detection member 3 in this embodiment is the rod shaft type structural member mentioned in the previous embodiments. By setting the second detection member 3, it is further convenient for the staff to perform inspection. During the inspection, the first detection member 2 is first fixed to the first hole 11 through the protrusion 21, and then the second detection member 3 is inserted from the hole of the second hole 12 away from the end of the groove 22 to confirm whether the second detection member 3 can extend into the groove 22. If it can extend into the groove 22, it means that the base 1 is qualified, otherwise it is unqualified.
[0043] In an embodiment of the angle detection mechanism, at least two limiting sections with different diameters are provided on the second detection member 3 so as to form a stepped surface at the connection, and the stepped surface is used for being snap-fitted to the inner wall of the second hole 12 .
[0044] In this embodiment, by setting the stepped surface, the second detection member 3 can abut against the inner wall of the second hole 12 when passing through the second hole 12, thereby achieving the purpose of limiting the position, thereby providing feedback that the second detection member 3 is in place.
[0045] In an embodiment of the angle detection mechanism, the side wall of the groove 22 is in a circular shape, and the detection end 31 is in a cylindrical shape.
[0046] In this embodiment, the circle is convenient for processing and also convenient for insertion, without having to find a specific angle for insertion, which is beneficial to improving detection efficiency.
[0047] In an embodiment of an angle detection mechanism, an observation hole is also provided on the first detection member 2, and the observation hole is connected to the groove 22. The extension direction of the observation hole passes through the bottom of the groove 22. The angle detection mechanism also includes a light emitting member, which is used to emit light toward the groove 22 through the second hole 12.
[0048] Different from the detection method of the previous embodiment, in this embodiment, the staff can determine whether the groove 22 is located on the extension path of the second hole 12 by observing the light emitted by the light emitting element on the bottom of the groove.
[0049] Specifically, the light emitting element may be a common laser pen. The observation hole may be arranged on the side wall of the upper end surface that penetrates through the groove 22 .
[0050] Preferably, a bull's eye can be engraved on the bottom of the groove 22, and the outer wall of the light emitting element can be set to match the shape of the second hole 12. When the light emitting element is embedded in the second hole 12, the light emitted by the light emitting element is parallel to the axial direction of the second hole 12, which can further improve the detection accuracy.
[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
