Abstract

PURPOSE:To rotate a head element and move it up and down freely and to move a container for chemical analysis arbitrarily, by rotating the head element with the rotation of the first supporting shaft, and moving the element up and down by moving the second supporting shaft up and down. CONSTITUTION:When a second motor 9 is rotated, a second supporting gear 8 is moved up and down through a drive gear 10 and a rack part. When a specified height is set and a first motor 3 is rotated in this state, a first supporting shaft 2 is rotated and a heat element 15, which is provided at a supporting plate 12 through a linking rod 18, is rotated in the direction of an arrow. The head element 15 is inserted in an engaging hole in a box for a sample to be analyzed (not shown) and the head element 15 is rotated. Then an engaging rod 15a is engaged with the engaging hole, and the box for the sample to be analyzed is lifted by the head element 15. For example, when the device is slidden on a guide rod 22 under the lifted state, the head element 15 can be moved to the other place.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to head preparation for chemical analysis, particularly for DNA analysis.
Chemical samples such as samples? This invention relates to improvements in means for reliably transferring the material to various atmospheres.

In this type of device, which has been used in the past, when transferring all the samples to various atmosphere parts within the analyzer, it is actually done manually, which is extremely inefficient. It was extremely dangerous as it contained powerful drugs.

The present invention aims to provide extremely effective means for quickly eliminating the above-mentioned drawbacks.
In particular, it is rotatably provided on a base body configured to be movable.
A bamboo support shaft, a second support shaft provided on the base body so as to be movable up and down in a direction parallel to the first support shaft, and a support fixed to the lower end of the second support shaft. A plate, a pair of rotating plates rotatably provided at both ends of the support plate, and a connecting rod for interlocking each rotating plate, with a first support shaft attached to one of the rotating plates. The head element is integrally provided and the head element is attached to the other rotating plate, and the head element is rotated by rotating the first support shaft.The head element is moved up and down by moving the second support shaft up and down. It is a configuration that can be used.

Hereinafter, in the drawings, which together with the drawings will explain in detail preferred embodiments of the head device for chemical analysis according to the present invention, the book indicated by reference numeral 1 is a base body, and the base body has a first support shaft 2. The first support shaft 2 is rotatably provided, and the first support shaft 2
is connected to the shaft 4 of the first motor 3 mounted on the base 1 so that it can be rotated.

A rotating plate 5 is attached to the upper end of the first support shaft 2 fL,
The same edge of the rotary plate 5 is located within the detection recess 7 of the first electrical detection element 6 mounted on the base 1. In this embodiment, the rotary plate 5 is a light-shielding plate. Furthermore, since each of the first electromagnetic detection elements 6 is composed of an optical switch element, the required openings (
(not shown) and the first electric detection element 6, the rotational position of the white roller plate 50 is detected and the rotational position of the first support shaft 20 is controlled.

Further, the base body 1 is provided with a second support shaft 8 at a position parallel to the first support shaft 2 so as to be movable up and down in the direction of the arrow. Moving gear 1 of motor 9
0 is engaged with the rack portion 11 of the second support shaft 8. At the lower end of the second support shaft 8, a support plate 12 having a substantially doglegged shape as a whole is fixed by bolts 13 in a direction perpendicular to the longitudinal direction of the second support shaft 8. , a first rotary plate 14 is mounted on one end of this support plate [2] and rotatably attached to it by a head element 15; A lower end 28 of the first support shaft 2 is rotatably penetrated and supported, and a second rotating plate 16 is rotatably supported at this lower end 2α. Said 1st.
A connecting rod 18 is operably connected to each end of the second rotating plates 14 and 16 via a pin 17, and the rotating plates 14 and 16 are simultaneously rotated by the connecting rod 18. They are movably connected.

A locking rod 15α is provided at the lower end of the head element 15 in a direction perpendicular to the axial direction of the head element 15, and by rotating the first support shaft 2,
The head element 15 is rotated via a connecting rod 18 and each rotating plate 14, 16t.

A pair of guide holes 19 are provided in the center of the main body 10t1.
. By sliding the guide holes 19 and 20, the base l
is moved. Further, a second electrical detection element 1 is attached to one end of the base 1, and a recess 23cL of this electrical detection element is mounted.
The case where the head device for chemical analysis according to the present invention is operated in the above-described configuration in which a bill blocking member supported by members not shown in this embodiment is interposed will be explained. First, when the second motor 9t rotates, the second support shaft 8 moves vertically via the wind gear 10 and the rack part 11, and the second motor 3 is rotated with the height set at the required height. Then, at the same time as the first support shaft 2 rotates, the head element 15 provided on the support plate 2 via the connecting rod 18 rotates in the direction of the arrow, and the head is inserted into the locking hole of the analysis sample box (not shown). When the element 15t is inserted and the head element is rotated, the locking rod 15α
engages the locking hole (not shown) with the analysis sample box (
(not shown) is lifted by the head element 15. Therefore, for example, by sliding the device 1 of the present invention on the guide rod n in this lifted state, the head element 15 can be moved to another location. Since the device has the structure and function described above, the head element can be configured to rotate and move up and down, allowing the chemical analysis container to be moved to any location.
