Description

Technical Field

[0001] This utility model relates to the field of flip cover mechanism technology, specifically a flip cover mechanism. Background Technology

[0002] In door opening and closing design, the traditional method is to use hinges to open and close the door, which requires external force to achieve the opening and closing of the door. The mainstream design generally uses hinges + gas springs to achieve the opening and closing of the door. The service life generally depends on the gas spring. For heavier doors, after repeated pushing and closing during the opening and closing process, the service life of the gas spring will be reduced, which will lead to uneven force on the door, thereby reducing the stability of the door opening and closing.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a flip cover mechanism.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a flip-top mechanism, including a box body, wherein the top of the box body is provided with a box cover, characterized in that:

[0006] A baffle, which is fixedly connected to one end of the outer wall of the box;

[0007] A hinge, wherein the hinge is located at both ends of the baffle and is fixedly connected to both ends of one side of the box cover;

[0008] A sheet metal bracket, which is fixedly installed at one end of the baffle;

[0009] Spring steel wire, which is rotatably connected to both ends of the lower side of the sheet metal bracket;

[0010] A pulley is rotatably connected to one end of a spring steel wire, and the pulley abuts against the outer wall surface of the hinge.

[0011] Furthermore, the top of the baffle has through holes at both ends near the box body, and the hinge is inserted into the through holes.

[0012] Furthermore, a cam limiting boss is fixedly connected to the outer wall surface of the hinge near the pulley, and a connecting shaft is provided between the two ends of the hinge.

[0013] Furthermore, a steel wire pressure plate is fixedly connected between the two sides of the lower end of the sheet metal bracket, and the steel wire pressure plate is used in conjunction with the spring steel wire.

[0014] Furthermore, a limiting screw is provided at one end of the hinge on the opposite side.

[0015] The advantages of this invention compared to existing technologies are as follows: Through the arrangement of a hinge, spring steel wire, and pulley, the hinge is propelled during opening and closing by the elasticity and torque of the spring steel wire repeatedly contacting and engaging with it. As the hinge moves backward, its contour pushes the pulley, keeping the lid open. Simultaneously, the pulley and hinge are locked at the opening angle by a limiting screw and a cam limiting boss, facilitating stable opening of the lid. After opening, the lid is closed by the torque of the spring steel wire, the hinge, and the door lock. This repeated movement constitutes the opening and closing motion of the lid, which is simple and practical. Compared to the traditional hinge + gas spring design, this invention improves the lifespan and reduces uneven force distribution of the gas spring after repeated opening and closing. Furthermore, this mechanism eliminates the need for a gas spring, resulting in a longer lifespan and space savings, significantly enhancing the stability of the lid's opening and closing and demonstrating good practicality.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 8 As shown, this embodiment proposes a flip-top mechanism, including a box body 1, a box cover 2 on the top of the box body 1, a baffle 3 fixedly connected to one end of the outer wall of the box body 1, and through holes at both ends of the top of the baffle 3 near the side of the box body 1, so that the components can be assembled together during use.

[0028] The baffle 3 is provided with hinges 4 at both ends. The hinges 4 are fixedly connected to both ends of one side of the cover 2. The hinges 4 are inserted into the through hole. A connecting shaft 42 is provided between the two hinges 4. The stroke and position of the hinges 4 are designed according to the opening and closing angle of the cover when in use.

[0029] A sheet metal bracket 5 is fixedly installed at one end of the baffle 3. Spring steel wires 6 are rotatably connected to both ends of the lower side of the sheet metal bracket 5. A steel wire pressure plate 61 is fixedly connected between the two sides of the lower end of the sheet metal bracket 5. The steel wire pressure plate 61 and the spring steel wire 6 are used in conjunction. All of the above are existing technologies and will not be described in detail here. The spring force and torque of the spring steel wire 6 when it repeatedly contacts and cooperates with the hinge 4 will push the hinge 4 to realize the opening and closing of the door.

[0030] One end of the spring steel wire 6 is rotatably connected to a pulley 7. The pulley 7 abuts against the outer wall surface of the hinge 4. When the hinge 4 moves backward, the pulley 7 is pushed by the reaction force of the spring steel wire 6. At this time, the box cover 2 is in the open state.

[0031] A cam limiting boss 41 is fixedly connected to the outer wall surface of the hinge 4 near the pulley 7. A limiting screw 8 is provided at one end of the opposite side of the hinge 4. The opening and closing angle between the pulley 7 and the hinge 4 is locked by the limiting screw 8 and the cam limiting boss 41.

[0032] In practical implementation, the various components are assembled together. During the opening and closing of the lid 2, the lock of the box body 1 is first opened. Then, the spring wire 6 and the hinge 4 are pushed by the elasticity and torque of repeated contact between them. When the hinge 4 moves backward, the contour of the hinge 4 pushes the pulley 7 to move. At this time, the lid 2 is in the open state. At the same time, the pulley 7 and the hinge 4 are locked at the opening angle by the limiting screw 8 and the cam limiting boss 41. After the lid 2 is opened, the lid is closed by the torque of the spring wire 6, the cooperation of the hinge 4, and the lock. 2. The repeated movement, namely the opening and closing movement of the lid 2, facilitates stable opening and closing of the lid 2. Furthermore, by utilizing the toughness and elasticity of the spring steel wire 6, it is possible to open and close the lid with a relatively heavy load and achieve a self-locking angle. This is simple and practical, thus replacing the traditional hinge + gas spring door opening and closing structure. Compared with the traditional hinge + gas spring, the service life of the gas spring and the uneven force distribution are improved after repeated opening and closing. Moreover, this mechanism does not require a gas spring, has a long service life, and saves space, which are significant advantages. It also improves the stability of the lid opening and closing and has good practicality.
