Description

A drum-type key delivery box Technical Field

[0001] The utility model relates to the technical field of delivery boxes, in particular to a delivery box for placing keys and being convenient for taking out and putting in keys. Background Art

[0002] At present, there is a demand for centralized key collection in some places. That is, after users use a certain place, they need to deliver the keys to a certain place so that the managers of the place can regularly take out the keys from the key delivery place, so as to save manpower and eliminate the need to arrange special personnel to receive the keys from the users and then store them. For this purpose, it is necessary to set up facilities such as key storage boxes in the place. The storage boxes should not only be convenient for delivery but also safe to use to prevent others from using tools to take out the keys from them.

[0003] Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide a drum-type key delivery box.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a roller-type key delivery box, comprising a box body, a box door arranged on the front side of the box body, a cover plate arranged on the upper end of the box body and a flip cover hinged to the box body at one end, wherein a delivery port is provided in the cover plate; further comprising a accommodating portion arranged in the box body and below the delivery port, a roller movably arranged in the accommodating portion, and connecting members hinged to the flip cover and the roller at both ends respectively; the accommodating portion is provided with a bottom opening, and the roller is provided with a side opening; when the flip cover is flipped upward, the roller rotates relative to the accommodating portion, and when the side opening is exposed from the delivery port or before the side opening is exposed, the bottom opening and the side opening are completely separated; when the flip cover is fully lowered, at least part of the side opening is aligned with the bottom opening.

[0006] Technical effect: in the initial state, the flip cover is placed flat. When the key needs to be delivered, the flip cover is flipped at a certain angle until the side opening of the roller is exposed from the delivery port, that is, when a part of the side opening is exposed, the side opening and the bottom opening are completely separated at this time, and tools such as iron hooks cannot be inserted into the box through the delivery port; after the key is delivered, the flip cover is lowered, and the roller rotates relative to the accommodating part. When the bottom opening is aligned with the part of the side opening, the key falls into the box, and the key delivery is completed; the use of this utility model is not only safe, but also can prevent the key placed in the box from being taken out, that is, it has a good anti-theft function; and it is easy to use.

[0012] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and implementation methods.

[0013] As shown in Figures 1, 3, and 4, an embodiment of the present invention provides a drum-type key delivery box for storing keys, such as keys used in public places. After storage, the box is opened by a manager to collect the keys. The delivery box comprises a box body 1, a door 2 provided at the front of the box body, a cover 3 provided at the upper end of the box body, and a flip cover 4 hinged to the box body at one end. The box body 1 and cover 3 are both made of hardware and are integrally formed.

[0014] In order to deliver the key, the cover plate 3 is provided with a delivery port 301; it also includes a accommodating portion 5 provided in the box body 1 and below the delivery port, a roller 6 movably provided in the accommodating portion 5, and a connecting member 7 hinged to the flip cover 4 and the roller at both ends; the accommodating portion 5 is provided with a bottom opening 501, and the roller 6 is provided with a side opening 601; as shown in Figures 2 and 5, with the flip cover lowered as the initial state, when the flip cover 4 is flipped upward, the roller rotates relative to the accommodating portion 5 driven by the connecting member 7, and when the side opening 601 is exposed from the delivery port 301 or before the side opening is exposed, the bottom opening 501 is completely separated from the side opening 601. During this process, when a portion of the side opening is exposed from the delivery port, or before the side opening is exposed from the delivery port, that is, when at least a portion of the side opening is exposed from the delivery port, the bottom opening and the side opening are completely separated. This structure completely prevents tools such as hooks from being inserted into the box body 1 through the delivery port, thus achieving a good anti-theft effect. When the flip cover 4 is fully lowered, at least a portion of the side opening 601 is aligned with the bottom opening 501, that is, at least a portion of the side opening is aligned with the bottom opening. As shown in FIG5 , in this embodiment, when the flip cover is fully lowered, the side opening and the bottom opening are completely aligned. In other words, the accommodating portion 5 here actually serves as an anti-theft device.

[0015] As shown in Figures 2 and 4, the accommodating portion 5 is composed of two folding plates 502 and two end plates 503 respectively arranged at both ends of the two folding plates, that is, the two end plates are respectively fixed at the two ends of the two folding plates and the end plates are perpendicular to the folding plates; specifically, each folding plate is integrally formed by a vertical plate 502a, a first inclined plate 502b, and a second inclined plate 502c, and the upper side of the vertical plate 502a is fixedly connected to the inner bottom surface of the cover plate; that is, the upper edge of each folding plate 502 is fixedly connected to the inner bottom surface of the cover plate 3, and the gap between the lower edges of the two folding plates 502 forms the bottom opening 501, that is, the gap between the lower edges of the two second inclined plates 502c is the bottom opening.

[0016] As shown in Figures 2 and 5, in this embodiment, the drum 6 includes two bottom plates 602, a side ring body 603 disposed between the two bottom plates, and the side opening 601 disposed within the side ring body 603. The two bottom plates 602 are respectively located inside the two end plates 503 and are hingedly connected to the two end plates. Here, the side ring body is composed of several square side plates spliced ​​together, that is, there is a virtual ring body with a regular polygonal cross-section, and the side ring body is part of the virtual ring body. With this structure, the drum and the two folding plates 502 are tightly attached during rotation.

[0017] Specifically, as shown in FIG. 4 , the connecting member 7 is two slender metal plates, the upper ends of which are hinged to the bottom surface of the flip cover 4 , and the lower ends of which are hinged to the bottom plate 602 .

[0018] As shown in FIG. 4 , the hinge position a between the lower end of the connecting member 7 and the bottom plate 602 is located outside the side opening, and the position is close to the edge of the bottom plate 602 .

[0019] In summary, with the delivery box of the present invention, at least when the side opening 601 is partially exposed from the delivery port 301, the side opening 601 is completely separated from the bottom opening 501, so that tools such as iron hooks cannot be inserted into the box body 1 through the delivery port 301; after the key is put in, the flip cover 4 is lowered, and the roller 6 rotates relative to the accommodating portion 5. When the bottom opening is aligned with a partial area of ​​the side opening, the key falls into the box body 1, and the key delivery is completed; the use of the present invention is not only safe, but also can prevent the key placed in the box body from being taken out, that is, it has a good anti-theft function; and it is easy to use.
