Description

Shell assembly devices of nucleic acid extraction appearance

Technical Field

The utility model relates to the field of machinery, in particular to an experimental instrument, and particularly relates to a shell assembling mechanism of a nucleic acid extractor.

Background

The nucleic acid extractor is a commonly used medical experimental device, and the shell of the nucleic acid extractor needs to be reassembled during maintenance. The parts of the shell of the existing nucleic acid extractor have large volume and heavy mass, the assembly by a single person is very difficult, and the assembly efficiency is greatly influenced by the cooperation of multiple persons.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a shell assembling mechanism of a nucleic acid extractor, which aims to solve the technical problems that the shell of the nucleic acid extractor in the prior art cannot be assembled by a single person and has low assembling efficiency.

In order to achieve the above purpose, the utility model provides the following technical scheme:

the utility model provides a shell assembly devices of nucleic acid extraction appearance, includes a base, a preceding shell, a back shell the downside of base, follow the edge of base be provided with four at least backing sheets, arbitrary one the edge of backing sheet exceed the edge of base, preceding shell with back shell set up the base on, two at least the backing sheet set up the below of preceding shell, two at least the backing sheet set up the below of back shell.

Furthermore, at least four fixing feet are arranged below the base.

Furthermore, the supporting pieces are symmetrically arranged along the center line of the base.

Furthermore, the support sheet is arranged on the lower side of the base through a support screw.

Further, the front shell and the rear shell are arranged on the upper side of the base through fixing screws.

Furthermore, the number of the supporting sheets is at least eight, and at least four supporting sheets are arranged below the front shell and the rear shell respectively.

The working principle is as follows:

place preceding shell, back shell on the base, surpass the effect of the part of base through the backing sheet edge and play the auxiliary stay to the shell of top, do not need other instrument to assist or other people to hold in the palm to hold up and can one accomplish the assembly.

Compared with the prior art, the utility model has the beneficial effects that: simple structure, the assembly process is convenient, and assembly efficiency is high.

Detailed Description

Example 1

Referring to fig. 1, fig. 2, and fig. 3, the present invention provides a technical solution:

the utility model provides a shell assembly devices of nucleic acid extraction appearance, includes a base 1, a preceding shell 4, a back shell 5, at the downside of base 1, along the edge of base 1 be provided with four at least backing sheets 2, the edge of arbitrary backing sheet 2 surpasss the edge of base 1, preceding shell 4 and back shell 5 set up on base 1, two at least backing sheets 2 set up the below of shell 4 in the front, two at least backing sheets 2 set up the below of shell 5 in the back.

Furthermore, at least four fixing feet are arranged below the base 1.

Further, the support pieces 2 are symmetrically arranged along the center line of the base 1.

Specifically, the support of the support sheet 2 to the front housing 4 and the rear housing 5 is uniformly distributed, and no inclination occurs.

Further, a support piece 2 is disposed at a lower side of the base 1 by a support screw 3.

Further, a front case 4 and a rear case 5 are provided on the upper side of the base 1 by fixing screws 6.

Furthermore, the number of the support sheets 2 is at least eight, and at least four support sheets 2 are respectively arranged below the front shell 4 and the rear shell 5.

Specifically, the larger the number of the support pieces 2 is, the more comprehensive the auxiliary support effect on the front housing 4 and the rear housing 5 is.

The assembly process of this embodiment:

step one, a base 1 is placed on a workbench and adjusted to be in a horizontal state;

placing the front shell 4 on the base 1 from the front end of the base 1, and fastening the front shell 4 at the front end of the base 1 through the fixing screws 6, wherein in the process, the supporting sheets 2 around the front end of the base 1 play a role of auxiliary supporting for the front shell 4, and the front shell 4 is not easy to shake or fall down;

step three, placing the rear shell 5 on the base 1 from the rear end of the base 1, fastening the rear shell 5 at the rear end of the base 1 through the fixing screws 6, in the process, the supporting sheets 2 around the rear end of the base 1 play a role of auxiliary support for the rear shell 5, and the rear shell 5 is not easy to shake and fall down.
