Abstract
Description
Technical Field
[0001] The present invention relates to a lid processing device, and more specifically, to a lid fixing and ejecting device. Background Art
[0002] In the prior art, in many cases, it is necessary to press the lid, and then take it out after pressing. There are many forms of lid pressing devices in the prior art, but the structures of the pressing devices in the field of microfluidics are very complex and the costs are very high.
[0003] In view of the above technical problems, there is an urgent need in the market for a lid fixing and ejecting device with a simple structure, simple operation, and relatively low processing and pressing costs. Summary of the Invention
[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a lid fixing and ejecting device with a simple structure and uniform pressing force.
[0005] To solve the above technical problems, the present invention provides the following technical solutions:
[0006] A lid fixing and ejecting device, which includes a base, the base is set in an "L" shape, with a rotating shaft hinge seat arranged at its upper end and a sunken engaging position arranged inside; a rotating cover plate, the rotating cover plate is hinged above the base, and its length is equivalent to that of the base; a swing door, the swing door is arranged at the opening formed by the rotating cover plate and the base, the swing door includes a cover plate, a hinge plate and a connecting plate, the hinge plate and the cover plate extend in opposite parallel directions at both ends of the connecting plate, and one end of the connecting plate where it coincides with the hinge plate is hinged to the base; a connecting rod, the connecting rod is arranged between the rotating cover plate and the swing door, one end of the connecting rod is hinged to the rotating cover plate, and the other end is hinged to the hinge plate; an ejecting mechanism, the ejecting mechanism includes an ejecting spring arranged on the inner wall and an ejecting button on the inner side of the swing door.
[0007] Further, the ejecting button is arranged in the middle of the contact part between the swing door and the base, its inner side is set in a slope shape, and a return spring is arranged at the connection part between the bottom and the base.
[0008] Further, a limiting groove is arranged within the stroke of the return spring at the bottom of the ejecting button, and a limiting pin is arranged on the base corresponding to the limiting groove.
[0009] Further, when the swing door is closed, the connecting rod is parallel to the cover plate.
[0010] Further, the hinge structure is set in the form of a rotating shaft hinge.
[0011] The lid fixing and ejecting device of this technical solution includes a base. The base is set in an "L" shape, with a rotating shaft hinge seat provided at its upper end and a sunken engaging position inside. A rotating cover plate, which is hinged above the base and has a length equivalent to that of the base. A revolving door, which is arranged at the opening formed by the rotating cover plate and the base. The revolving door includes a cover plate, a hinge plate, and a connecting plate. The hinge plate and the cover plate extend in opposite directions and parallelly at both ends of the connecting plate. One end of the connecting plate where it coincides with the hinge plate is hinged to the base. A connecting rod, which is arranged between the rotating cover plate and the revolving door. One end of the connecting rod is hinged to the rotating cover plate, and the other end is hinged to the hinge plate. An ejecting mechanism, which includes an ejecting spring arranged on the inner wall and an ejecting button on the inner side of the revolving door. The height of the box body is equivalent to the height of the inner cavity of the lid pressing device of this technical solution. During use, the box body is placed into the inner cavity, and then the revolving door is pulled. When the revolving door rotates and the cover plate moves upward, at the same time, the hinge plate also moves downward, driving the connecting rod to move downward, and the rotating cover plate closes downward, thereby pressing the upper lid of the box body located below the rotating cover plate. When the cover plate is closed, the connecting rod drives the rotating cover plate to reach the tightest state, and the pressing is completed. After the lid is pressed, the process of taking out the box body is as follows: The finger presses the ejecting button inward. The slope on the inner side of the ejecting button contacts the box body, applies force to the box body, the ejecting spring is under pressure and generates a reaction force, and cooperates with the ejecting button to eject the box body from the engaging position.
[0012] In this technical solution, the ejecting button is arranged in the middle of the contact part between the revolving door and the base. Its inner side is set in a slope shape, and a return spring is arranged at the connection between the bottom and the base. The slope shape is more conducive to applying force and ejecting the box body, and the return spring can make the ejecting button quickly return to its original position.
[0013] In this technical solution, a limiting groove is arranged within the stroke of the return spring at the bottom of the ejecting button, and a limiting pin is arranged on the base corresponding to the limiting groove. The setting of the limiting device limits the stroke of the ejecting button, enabling the ejecting button to move within the stroke range.
[0014] When the revolving door of this technical solution is closed, the connecting rod is parallel to the cover plate. This design method can make the box body receive uniform force when the pressing device presses, and the force is the greatest when the cover plate is closed.
[0015] In this technical solution, the hinge structure is set in the form of a rotating shaft hinge. This hinge method is relatively common and relatively stable and reliable.
[0016] The lid fixing and ejecting device of this technical solution has a simple structure, applies force evenly, is simple and reliable in operation, can easily realize the pressing and ejecting actions of the lid, and is very practical.
[0017] On the basis of conforming to the common general knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain the embodiments of the present invention. Description of the Drawings
