Description

Technical Field

[0001] This utility model relates to the field of frame and cover technology, and more specifically, to a rotatable, quick-closing frame cover and frame. Background Technology

[0002] A frame is generally a container with a certain shape and structure made of materials such as plastic or metal. It is used to hold, classify, or protect items. Frames come in various shapes, with square and round structures being common. They are widely used in daily life and industrial production, such as storage boxes and logistics boxes for storing various sundries and tools. A frame lid is a component that matches the frame and covers its opening. Its main function is to seal the opening and prevent items from being exposed. Traditionally, frame lids and frames are designed separately. The lid is usually manually pressed to close, and then manually lifted to open for taking out or placing items. Once opened, the lid needs to be removed and placed separately, taking up space and easily forgotten. Furthermore, if the lid is tightly closed, it requires prying open the edges with fingers, which is inconvenient, especially in situations where frequent opening and closing of the frame is necessary, affecting operational efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a rotatable, quick-closing frame cover and frame that can rotate flexibly, does not occupy space, is easy to operate, and has high efficiency.

[0004] To achieve the above objectives, the first aspect of this utility model provides a rotatable, quick-closing frame cover, including a frame cover, a connecting plate, a hinge, and a locking fastener. One side of the hinge is fixedly connected to the bottom of the top surface of the frame cover by the locking fastener, and the other side of the hinge is fixed to one side of the connecting plate by the locking fastener. The connecting plate includes a first limiting plate, a top plate, and a second limiting plate. The first and second limiting plates are parallel and spaced apart. The top plate is horizontally fixed between the top of the first and second limiting plates. The first and second limiting plates and the top plate together form a U-shaped opening groove. The frame cover can be flipped up and down relative to the top plate of the connecting plate by the hinge.

[0005] Preferably, the hinge is configured as a hinge, a hinge chain, or a torsion spring pivot.

[0006] Preferably, the hinge includes a first leaf, a second leaf, and a pivot pin. The rotating ends of the first and second leaf are respectively sleeved on the pivot pin, and the first and second leaf are respectively capable of rotating relative to the pivot pin.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Implementation 1

[0023] Please refer to Figure 1 The first embodiment of this utility model provides a rotatable, quick-closing frame cover, including a frame cover 1, a connecting plate 2, a hinge 3, and a locking device. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2As shown, one side of the hinge 3 is fixedly connected to the bottom of the top surface of the frame cover 1 by a fastener, and the other side of the hinge 3 is fixed to one side of the connecting plate 2 by a fastener. The connecting plate 2 includes a first limiting plate 21, a top plate 22, and a second limiting plate 23. The first limiting plate 21 and the second limiting plate 23 are parallel and spaced apart. The top plate 22 is horizontally fixed between the top of the first limiting plate 21 and the top of the second limiting plate 23. The first limiting plate 21, the second limiting plate 23, and the top plate 22 are combined to form a U-shaped opening groove 24. The frame cover 1 can be flipped up and down relative to the top plate 22 of the connecting plate 2 by the hinge 3.

[0025] like Figure 3 As shown, the height of the first limiting plate 21 of the connecting plate 2 is higher than the height of its second limiting plate 23.

[0026] In this embodiment, the hinge 3 can be configured as a hinge, a hinge chain, or a torsion spring pivot. Preferably, two hinges 3 are provided and connected to both sides of the frame cover 1 and the connecting plate 2, respectively. Of course, in other embodiments, other hinges 3 capable of enabling the frame cover 1 to rotate can also be used, and this embodiment does not impose any restrictions on them.

[0027] like Figure 4 As shown, in a specific implementation, the hinge 3 is preferably configured as a hinge, which may include a first leaf 31, a second leaf 32, and a pivot pin 33. The rotating ends of the first leaf 31 and the second leaf 32 are respectively sleeved on the pivot pin 33, and the first leaf 31 and the second leaf 32 can rotate relative to the pivot pin 33. In this embodiment, the use of a hinge makes the opening and closing operation of the frame cover 1 smoother. Through the cooperation of the pivot pin 33 and the two leaves, the stability and reliability of the rotation of the frame cover 1 are ensured, and the cost is low.

[0028] Specifically, the locking device can be configured as a number of locking screws 41. A number of first threaded holes 10 are provided through the bottom edge of the frame cover 1. A number of second threaded holes 20 are provided through the top edge of the first limiting plate 21 of the connecting plate 2. A number of third screw holes corresponding to the first threaded holes 10 and the second threaded holes 20 are provided through the first plate 31 and the second plate 32. The locking screws 41 pass through each of the third screw holes and are threadedly connected to the first threaded holes 10 and the second threaded holes 20, thereby realizing the hinge connection between the frame cover 1 and the hinge.

[0029] Among them, the locking screw 41 can ensure a firm connection between the frame cover 1, the hinge 3 and the connecting plate 2, making the structure of the entire frame cover 1 more stable and less prone to loosening during use.

[0030] Implementation 2

[0031] Please refer to Figure 5The second embodiment of this utility model provides a frame, including a frame body 5 and a rotatable, quick-closing frame cover as described in the first embodiment. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 5 and Figure 6 As shown, the top of the frame body 5 is open and the outer perimeter and bottom are closed. The frame body 5 may include a bottom plate 51 and a side plate 52. The bottom edge of the side plate 52 is vertically surrounded on the outer side wall of the bottom plate 51. The U-shaped opening groove 24 of the connecting plate 2 is engaged with the top of the side plate 52. The frame cover 1 can be flipped up and down with the hinge 3 of the connecting plate 2 as the center, so as to open and close the opening of the frame body 5.

[0033] Specifically, the top of the side panels 52 are all folded outward to form flanges 53, and the width of the U-shaped opening groove 24 is greater than the width of the flanges 53.

[0034] In this embodiment, the frame body 5 can be square, round or irregularly shaped, as long as the shape of the frame cover 1 corresponds to or is slightly larger than the opening shape of the frame body 5. This embodiment does not limit the shape of the frame body. The opening groove 24 of the connecting plate 2 is designed with a U-shaped structure, which can accommodate side plates 52 and flanges 53 of different thicknesses. The first limiting plate 21, top plate 22 and second limiting plate 23 can all be designed as arcs, not limited by the shape of the frame body 5, as long as they are securely fastened and do not loosen.

[0035] Preferably, the design of the first limiting plate 21 of the connecting plate 2 being higher than the second limiting plate 23 creates a height difference between the two. When the handle 54 is lifted to move the frame body 5 and causes it to shake, the connecting plate 2 can be restricted from moving horizontally, making the connection between the connecting plate 2 and the frame body 5 more stable, and also facilitating the cooperation between the opening slot 24 and the upper flange 53 of the side plate 52.

[0036] In specific implementation, such as Figure 7 As shown, the connecting plate 2 is fixed to the side plate 52 of the frame body 5 and rotates to connect with the frame cover 1, so that the frame cover 1 can be stably installed on the frame body 5 and can be flipped. The frame cover 1 can be opened and closed flexibly, making it convenient for users to store and retrieve items in the frame.

[0037] In summary, the rotatable quick-closing frame cover of this utility model can quickly open and close the frame body, avoiding the problems of traditional split frame covers that need to be placed separately and are easily forgotten. It does not take up extra space, is convenient for taking out and placing items, and improves efficiency. It is especially suitable for occasions where the frame body is frequently opened and closed, such as express sorting and material retrieval.

[0038] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
