Description
Technical Field
[0001] This utility model relates to the field of storage box technology, and in particular to a built-in top cover opening push structure. Background Technology
[0002] In existing box structures, two telescopic rods are typically arranged in pairs between the lid and the box body. These rods are used to automatically flip the lid open after the lid is unlocked. Furthermore, to overcome the problem that the angle between the telescopic rod and the lid is close to a right angle when the lid is open, which can prevent the lid from opening automatically, a thrust mechanism is also installed on the box body. This mechanism applies an initial thrust to the lid to ensure it flips open smoothly.
[0003] However, the existing structure has the following drawbacks: 1. The applied force acts directly on the lid, which can easily damage the lid; 2. It cannot be well hidden inside the box, and the structural design is not compact enough, resulting in the occupation of the box space; 3. The structural design is not stable and reliable enough.
[0004] Therefore, how to design a built-in top cover opening thrust structure that is simpler and more reasonable in structure, can protect the box cover, has a more reasonable layout, and is more stable and reliable in operation has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a built-in top cover opening thrust structure with a simpler and more reasonable structural design, which can protect the box cover, has a more reasonable layout, and is more stable and reliable in operation.
[0006] To achieve the above objectives, this utility model provides a built-in top cover opening thrust structure, including a box cover hinged to the upper open end of a box body via a hinge structure. Telescopic rods are provided at both ends inside the box body, with the distal ends of the telescopic rods hinged to the distal ends of the box cover. The hinge structure includes a hinge, comprising a first hinge piece fixed to the box body and a second hinge piece fixed to the box cover. A thrust mechanism is also provided on the box body, having a vertically arranged push rod. A vertically penetrating clearance hole is provided on the first hinge piece, and the upper end of the push rod vertically passes through the clearance hole and abuts against and supports the second hinge piece, causing the first and second hinge pieces to have an opening tendency, thus giving the box cover a flipping motion tendency.
[0007] In this structure, the push rod of the thrust mechanism passes through the clearance hole of the first hinge piece and then abuts against and supports the second hinge piece. This ensures that the force is applied to the hinge, better avoiding direct contact between the lid and the push rod, thus better protecting the lid from damage. Furthermore, the more rational selection of the force application point makes the operation more stable and reliable, and also better ensures that the first and second hinge pieces have an opening tendency, allowing the lid to flip over.
[0008] Furthermore, the first and second hinge pieces are hinged together by a hinge shaft.
[0009] As an optimization, the first and second hinge pieces are each designed as elongated strips, arranged along the longitudinal direction of the housing and lid respectively. Furthermore, the first and second hinge pieces are fixed to the housing and lid by rivets. A clearance hole is provided at the midpoint of the longitudinal direction of the first hinge piece. Further, the length of the first and second hinge pieces matches the longitudinal dimension of the housing.
[0010] In this way, the hinge structure is more reasonable and easier to install and fix; the dimensions of the first and second hinge pieces are also more reasonable.
[0011] As an optimization, the upper end of the push rod has a rounded corner structure.
[0012] In this way, by designing rounded corners, the structural design becomes more reasonable.
[0013] As an optimization, the housing includes a rear panel on the rear side. A mounting plate with an overall rectangular structure and arranged longitudinally along the housing is installed on the upper inner side of the rear panel. The mounting plate bends and extends rearward on both its upper and lower sides to form an upper mounting flange and a lower mounting flange. A first hinge piece is attached to the upper mounting flange, and a mating notch is provided on the upper mounting flange corresponding to the clearance through hole. A support block is installed on the rear side of the mounting plate, and a vertically penetrating mounting hole is provided on the support block. The lower end of a push rod passes through the mounting hole and extends downwards, with a limiting head provided at the lower end of the push rod. A helical spring is sleeved on the push rod, with the lower end of the helical spring abutting against the support block and the upper end of the helical spring abutting against the abutting protrusion at the upper end of the push rod, giving the push rod an upward movement tendency. The upper end of the push rod passes sequentially through the mating notch and the clearance through hole.
[0014] This design makes the overall structure more rational and allows for better concealment of the push rod. Furthermore, the push rod can better provide thrust to the second hinge plate.
[0015] As an optimization, a limit nut is provided at the threaded end of the push rod to form the limit head.
[0016] In this way, by setting a limit nut, the effective length of the push rod can be adjusted more easily.
[0017] As an optimization, a rectangular clearance opening is provided on the lower mounting flange and corresponding to the limiting head, such that the lower end of the push rod passes through the clearance opening and extends below the lower mounting flange.
[0018] This makes it easier to arrange the push rods and results in a more rational structural design.
[0019] As an optimization, the support block includes a horizontal section and a vertical section. The horizontal section of the support block has the mounting hole. The outer side of the lower mounting flange bends upward and extends to form a mounting strip. The mounting strip has a mounting opening, and the corner position where the vertical section and the horizontal section of the support block meet is matched and set in the mounting opening.
[0020] In this way, the structural design of the support block is simpler and more reasonable, and it is also easier to install and arrange the support block.
[0021] As an optimization, the push rod includes a lower push rod mounting section and an upper push rod working section. The lower end of the push rod working section is provided with a threaded adjustment hole, and the upper end of the push rod mounting section is threadedly connected to the threaded adjustment hole. The lower end of the push rod working section is provided with the abutting flange, and the lower end of the push rod mounting section is provided with the limiting nut.
[0022] In this way, the structure of the push rod is simpler and more reasonable, and it is easier to adjust it as needed.
[0023] Furthermore, a vertically arranged abutment limiting plate is provided on the rear side plate. The upper end of the abutment limiting plate is bent outward horizontally to form an abutment flange, and the lower end of the push rod can abut and support on the abutment flange to limit the vertical downward position of the push rod.
[0024] In this way, by setting an abutment limit plate, the structural strength can be enhanced on the one hand, and the limit function can be played on the other hand.
[0025] In summary, the above-mentioned structural design is simpler and more reasonable, can protect the box cover, has a more rational layout, and is more stable and reliable in operation. Attached Figure Description

[0039] In this structure, the push rod of the thrust mechanism passes through the clearance hole of the first hinge piece and then abuts against and supports the second hinge piece. This ensures that the force is applied to the hinge, better avoiding direct contact between the lid and the push rod, thus better protecting the lid from damage. Furthermore, the more rational selection of the force application point makes the operation more stable and reliable, and also better ensures that the first and second hinge pieces have an opening tendency, allowing the lid to flip over.
