Flip mechanism capable of bouncing to open and close

Abstract

The utility model discloses a flip cover mechanism capable of being opened and closed in a bouncing mode. The flip cover mechanism comprises a flip cover, an upper shell, a button spring, a button, a bouncing spring and a fixing base. The flip cover is connected with the upper shell through a shaft position and can be opened and closed. And the button spring and the button are placed in the groove of the upper shell. One end of the bouncing spring is installed on the fixed seat, and the other end abuts against the buckle position of the button. When the flip cover is in a closed state, the buckle of the flip cover ejects the bouncing spring and the button open. And when reaching the limiting position, the button clamps the buckle of the flip cover under the action of the button spring, and the bouncing spring is in a compressed state at the moment. When the flip cover needs to be opened, the button is manually pressed, the button spring is compressed, the buckle of the flip cover is separated from the limiting position of the button and pops up under the action of the bouncing spring till the bouncing spring abuts against the limiting position of the button, and the bouncing spring does not act on the flip cover and stops. The device is simple in structure, stable in work and high in reliability.

Description

Technical Field

[0001] This utility model relates to the field of printers, and in particular to a flip cover mechanism that can be opened and closed by a spring. Background Technology

[0002] In modern society, printers are becoming increasingly common. They are also widely used in medical laboratories. Printers make recording experimental data more convenient and accurate. However, in older printers, the flip-top mechanism often relied on the deformation of the plastic casing to achieve a locking effect. After repeated use, this could lead to insufficient locking force or even complete failure of the locking mechanism, resulting in a poor user experience. Summary of the Invention

[0003] To address the problems in current technology, this utility model provides a flip cover mechanism that can be opened and closed by a spring. The flip cover is fixed to the upper shell by a buckle. After the button is pressed, the buckle disengages, and the flip cover is pushed out and popped up by the action of a spring.

[0004] To achieve the above objectives, this utility model provides the following technical solution: When the flip cover is in the closed state, the flip cover's latch releases the spring and the button. Upon reaching the limit position, the button, under the action of the button spring, locks the flip cover's latch, at which point the spring is compressed. When it is necessary to open the flip cover, manually press the button; the button spring compresses, the flip cover's latch disengages from the button's limit position, and simultaneously springs out under the action of the spring spring until the spring spring reaches the button's limit position, at which point the spring spring stops exerting any force on the flip cover.

[0005] The beneficial effect of this utility model is that the flip cover and the upper shell are fixed not by plastic deformation and compression, but by a switchable mechanism to achieve the purpose of fixing or opening the flip cover. This will not cause wear and tear on the plastic that could lead to failure of the flip cover latch. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figures 1 to 7 This utility model provides an embodiment of a flip-top mechanism that can be opened and closed by spring, comprising a flip-top (1), an upper shell (2), a button spring (3), a button (4), a spring-loaded spring (5), and a fixing seat (6). The flip-top (1) and the upper shell (2) are connected by a shaft and can be opened and closed. The button spring (3) and the button (4) are placed inside the groove of the upper shell (2). One end of the spring-loaded spring (5) is mounted on the fixing seat (6), and the other end is pressed against the snap-fit ​​position of the button (4). The fixing seat (6) is connected and fixed to the upper shell (2) by snap-fit.

[0018] Working principle: When the flip cover (1) is closed, the latch of the flip cover (1) pushes open the spring (5) and the button (4). When it reaches the limit, the button (4) is locked by the button spring (3) and the latch of the flip cover (1). At this time, the spring spring (5) is in a compressed state. When it is necessary to open the flip cover (1), press the button (4) manually. The button spring (3) is compressed, the latch of the flip cover (1) is released from the limit of the button (4), and at the same time, it is popped out by the spring spring (5) until the spring spring (5) pushes the button (4) to the limit. The spring spring (5) stops acting on the flip cover (1).

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
