Description

Technical Field

[0001] The utility model relates to the field of trash cans, in particular to an aviation trash can with an edge chamfer anti-collision structure. Background Art

[0002] In order to facilitate people to throw garbage on an airplane, trash cans are placed, and the weight of the trash cans is reduced as much as possible. The existing metal rectangular structure trash cans generally include a base, a bracket, a side plate, etc. Four vertically upward brackets are welded at the four upper corners of the base, and then side plates are welded between two adjacent brackets. Since the connection between two adjacent side plates is at a right angle, it is easy for people to get injured when colliding with the edge. The right-angled structure also makes it difficult for stress to dissipate and is easy to crack. Its anti-impact ability is weak. And in order to ensure the firmness of the side connection, the whole needs to be welded, which also leads to an increase in the overall weight of the whole trash can. For this reason, we designed an aviation trash can with an edge chamfer anti-collision structure. Content of the Utility Model

[0003] To solve the technical problem that people are easily injured when colliding with the edge, the utility model provides an aviation trash can with an edge chamfer anti-collision structure.

[0004] The utility model is realized by adopting the following technical solutions: An aviation trash can with an edge chamfer anti-collision structure includes a base. A bottom plate is fixed inside the base. The base includes a bottom frame in a rectangular structure. The inner wall around the bottom frame is thickened and extended upward to form an extended frame. A plug-in groove is formed by the depression between the bottom frame and the extended frame. An outer frame cover is inserted into the plug-in groove. A protective arc plate is respectively riveted and fixed at the four corners of the outer surface of the outer frame cover. An upper frame is fixed above the outer surface of the outer frame cover.

[0005] As a further improvement of the above solution, a contact bottom is integrally bent inside the bottom frame, and an L-shaped structure is designed between the contact bottom and the inner wall of the extended frame. The bottom plate is placed above the four contact bottoms and welded between them. The bottom plate can be directly placed above the contact bottom from top to bottom, which is convenient for the installation and fixation of the bottom plate. Generally, the bottom plate is welded to the bottom frame to form a whole;

[0006] Part of the two adjacent contact bottoms is removed to form a bending notch. The whole extended frame is formed by bending a metal plate. The design of the bending notch enables the lower end of the metal plate to be bent at 90 degrees to form the contact bottom after being bent into a rectangular structure.

[0007] As a further improvement of the above solution, the outer frame cover includes a whole metal plate. The metal plate is continuously bent four times to form four side panels, and there is a bent portion with an arc structure between two adjacent side panels. The bent portion is a 1 / 4 circular structure, which can make the shape change of the part gentle, reduce stress concentration, make it not easy to crack, and increase the impact resistance.

[0008] The outermost bent portion is horizontally designed to form an extension portion, and the outer bent portion of the extension portion is formed with a docking portion with a horizontal design. The docking portion is welded to the innermost side panel. The whole outer frame cover is integrally bent and formed by one metal plate, so that it has only one weld seam, making it not easy to deform, and its weight is reduced compared with a rectangular frame composed of multiple plates welded together.

[0009] As a further improvement of the above solution, the thickness of the outer frame cover is the same as the width of the insertion slot. The inner wall of the outer frame cover contacts the outer side of the extension frame, and the two are fixed by riveting, which is convenient for quickly fixing the outer frame cover on the base and also convenient for subsequent fixing.

[0010] As a further improvement of the above solution, a butting frame is formed by the inwardly protruding part on the inner side of the lower end surface of the upper frame, and the outer length and width of the butting frame match the inner length and width of the outer frame cover, and the two are fixed by riveting. The upper frame can be directly clamped above the outer frame cover, which is convenient for the installation and fixation between the two.

[0011] As a further improvement of the above solution, mounting brackets are fixed by riveting on both the left and right side surfaces of the outer frame cover, and a handle is movably installed in the mounting brackets, which is convenient for moving the trash can.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The outer frame cover of the present utility model is bent from a single metal plate, and there is only one weld seam at its connection, making it not easy to deform. The whole base, upper frame and it are all fixed by riveting, and its weight is reduced compared with a rectangular frame composed of multiple plates welded together. The four corners of the outer frame cover have bent portions with a 1 / 4 circular structure, and together with the protective arc plates arranged outside it, it can make the shape change of the part gentle, reduce stress concentration, make it not easy to crack, increase the impact resistance, and also avoid easy bruising when people collide, improving safety.

[0014] 2. The aviation trash can consists of four parts: a base, an outer frame cover, a bottom plate and an upper frame. The outer frame cover can be directly inserted above the base, and the upper frame can be inserted above the outer frame cover, making the overall structure simple and also convenient for quick assembly and fixation.
