[0034] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0035] Embodiment 1

[0036] like Figures 2 to 7 As shown, the embodiment of the utility model provides a module panel that is easy to assemble and disassemble, including a panel body 1 and a quick locking mechanism.

[0037] Specifically, a slot structure 2 is provided at the bottom of the panel body 1 , and a silicone strip 3 is provided on the bottom wall or side wall of the slot structure 2 .

[0038] The quick locking mechanism includes a mounting plate 4, a limiting cylinder 5, a locking shaft 6 and a locking piece 7. The mounting plate 4 is mounted on the back of the panel body 1, and the mounting plate does not extend out of the edge of the panel body. The limiting cylinder 5 is fixedly mounted on the mounting plate 4, and a movable hole for the locking shaft 6 to be pulled out and rotated is provided in the limiting cylinder 5. The locking shaft 6 is movably mounted in the movable hole, and the locking piece 7 is fixedly mounted on the locking shaft.

[0039] The mounting plate 4 is provided with a first limiting groove 8 at one end thereof facing the limiting cylinder 5, and the limiting cylinder 5 is provided with a second limiting groove 9 at one end thereof facing the mounting plate 4, and the second limiting groove 9 cooperates with the first limiting groove 8 to limit the moving position of the locking piece 7;

[0040] When the locking shaft 6 rotates radially and the locking piece 7 is turned to the first position, the locking piece 7 is located in the first limiting groove 8 and is stuck between the limiting cylinder 5 and the panel body 1, and the top of the locking piece 7 extends out of the edge of the panel body 1;

[0041] When the locking shaft 6 rotates radially and the locking piece 7 is turned to the second position, the locking piece 7 can move back and forth between the second limiting groove 9 of the limiting cylinder 5 and the first limiting groove 8 of the mounting plate 4;

[0042] When the locking plate 7 is located in the second limiting groove 9 and the locking shaft 6 rotates radially to turn the locking plate 7 to the third position, the locking plate 7 is stuck between the limiting cylinder 5 and the mounting plate 4, and the top of the locking plate 7 does not extend out of the edge of the panel body 1.

[0043] In this embodiment, the panel body 1 is installed on the installation panel 15 of the nucleic acid synthesizer as an example, wherein a protrusion structure 10 is provided at the bottom of the installation panel 15 of the nucleic acid synthesizer. When installing the panel body 1, the slot structure 2 at the bottom of the panel body 1 is aligned with the protrusion structure 10 and pressed down, so that the protrusion structure 10 enters the slot structure 2, and then the top of the panel body 1 is pressed into the installation panel 15 of the nucleic acid synthesizer to complete the preliminary installation of the panel body 1.

[0044] After the panel body 1 is completely inserted into the panel window of the nucleic acid synthesizer, the locking shaft 6 is rotated so that the locking piece 7 enters the first limiting groove 8. At this time, the locking piece 7 contacts the inner wall of the panel of the nucleic acid synthesizer, and the locking and fixing of the panel body 1 is completed. When the panel body 1 needs to be removed, the locking shaft 6 is driven to make the locking piece 7 enter the second limiting groove 9. At this time, the locking piece 7 releases the locking of the panel body 1, and the panel body 1 can be removed.

[0045] In a specific embodiment, a screw hole 11 is provided on the mounting plate 4 , and the mounting plate 4 is mounted on the panel body 1 by screws passing through the screw holes 11 .

[0046] Furthermore, one end of the locking shaft 6 away from the limiting cylinder 5 passes through the panel body 1 and is installed with a knob 12 . The knob 12 is threadedly installed with the locking shaft 6 , and the knob 12 is provided with anti-slip grooves.

[0047] Specifically, when installing the quick locking mechanism, the locking shaft 6 passes through the panel body 1 at one end away from the limiting cylinder 5, and then the mounting plate 4 is installed on the side wall of the nucleic acid synthesizer panel using screws, and finally the knob 12 is threadedly installed on the locking shaft 6.

[0048] It should be noted that, in order to improve the anti-slip performance of the knob 12 , anti-slip grooves are provided on the knob 12 to increase the friction between the operator's hand and the knob 12 .

[0049] Furthermore, a compression spring 14 is disposed in the limiting cylinder 5 , and two ends of the compression spring 14 are respectively connected to the locking piece 7 and the inner bottom surface of the limiting cylinder 5 .

[0050] Specifically, after the compression spring 14 is arranged between the locking piece 7 and the inner bottom surface of the limiting cylinder 5, the elastic force of the compression spring 14 pushes the locking piece 7 to move toward the side of the panel body 1. After the compression spring 14 is arranged, the locking and unlocking methods of the panel body 1 are as follows:

[0051] When the locking position is released (i.e., the locking piece 7 is located at the second limit groove 9), the knob 12 to 45° is rotated counterclockwise to make the locking piece 7 on the locking shaft 6 leave the second limit groove 9. Under the action of the elastic force of the compression spring 14, the locking piece 7 moves to the mounting plate 4 and stops. Then the knob 12 to 45° is rotated counterclockwise again to make the locking piece 7 located on the first limit groove 8. At this time, the outer end of the locking piece 7 is in contact with the inner wall of the synthesizer panel, which limits the separation of the panel body 1 from the synthesizer panel, thereby completing the rapid locking of the panel body 1.

[0052] When in the locking position (i.e., the locking piece 7 is located at the first limit groove 8), the knob 12 is rotated clockwise to 45° to make the locking piece 7 leave the first limit groove 8, and then the knob 12 is pressed to make the locking piece 7 enter the second limit groove 9, and then rotated clockwise 45°, the locking piece 7 is located on the second limit groove 9, at this time, the outer end of the locking piece 7 is separated from the inner wall of the synthesizer panel, the locking state between the panel body 1 and the nucleic acid synthesizer is released, and the panel body 1 is quickly unlocked.

[0053] In a specific embodiment, the compression spring 14 is sleeved outside the locking shaft 6, and the compression spring 14 is in close contact with the outer wall of the locking shaft 6 and in sliding contact. The compression spring 14 is sleeved outside the locking shaft 6, and the compression spring 14 is in close contact with the outer wall of the locking shaft 6 and in sliding contact. During the compression process of the compression spring 14, the locking shaft 6 can effectively prevent the compression spring 14 from being excessively twisted, thereby increasing the service life of the compression spring 14.

[0054] Furthermore, the first side wall of the first limiting groove 8 is vertically arranged, the second side wall of the first limiting groove is inclined, the inclination angle of the second side wall is 45°, and the rotation angle between the first position and the third position is 90°;

[0055] Specifically, when the locking piece 7 is rotated to the first position, the locking piece 7 contacts the first side wall of the first limiting groove 8, and when the locking piece 7 is rotated to the second position, the locking piece 7 contacts the second side wall of the first limiting groove 8.

[0058] The installation panel 15 is fixedly mounted on the main housing, and the installation panel 15 has an opening, and a protruding structure 10 is arranged at the edge of the opening. The panel body 1 of the module panel is arranged in the opening, and a slot structure 2 cooperating with the protruding structure 10 is arranged at the edge of the panel body 1. The valve 16 is integrated on the module panel and is located on the back of the panel body 1;

[0059] A strip-shaped elastic component 3 is disposed on the bottom wall or the side wall of the slot structure 2 . After the protrusion structure 10 and the slot structure 2 are assembled, the strip-shaped elastic component 3 is elastically deformed and tightly joined.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
