Description

Technical Field

[0001] This application relates to the technical field of delivery boxes, and particularly to a panel self - returning mechanism for a delivery box. Background Art

[0002] In order to facilitate postmen to deliver mails, parcels and other items, individuals, enterprises or other groups often need to set up a delivery box outdoors. The postman delivers mails and other items through the delivery opening, and the user can open the box door of the delivery box at any time to take out the items.

[0003] Most delivery boxes will have at least one rotatable panel as the cabinet door for taking and placing items. Such a cabinet door often uses a simple shaft to rotate the panel. The panel needs to keep a certain distance from the opening of the delivery box to rotate. In this rotation method, whether the shaft is horizontally placed or vertically placed, the panel will often rub against the box body due to gravity or the overall tendency of the movable panel to one side, resulting in paint peeling or the movable panel becoming difficult to rotate. This phenomenon not only appears in delivery boxes, but also appears in many boxes with rotatable movable panels.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a panel self - returning mechanism for a delivery box to solve one of the above - mentioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problems is a panel self - returning mechanism for a delivery box, which includes: a box body, with several openings on one side; a rotating connection shaft, with springs sleeved at both ends to form an annular convex part to abut against one end of the spring, and the rotating connection shaft is rotatably arranged at both ends of the opening; a movable panel, rotatably arranged on the rotating connection shaft, and abutting surfaces are formed at both ends of the movable panel to be penetrated by the rotating connection shaft and abutted by one end of the spring; the spring is used to apply a force that makes both ends of the movable panel move outward simultaneously to make the movable panel automatically return to the central position.

[0007] In some embodiments, one of the openings or the openings is a delivery opening, the delivery opening is opened above the box body, and the rotating connection shaft is horizontally placed at the top of the delivery opening.

[0008] In some embodiments, one of the openings or the openings is a pick - up opening, the pick - up opening is opened on the front panel of the box body, and the rotating connection shaft is vertically placed on one side of the pick - up opening.

[0009] In some embodiments, the opening includes a delivery port and a pick-up port. The delivery port is opened above the box body, and the pick-up port is opened below the box body. The first rotating connection shaft is horizontally arranged, and the second rotating connection shaft is vertically arranged.

[0010] In some embodiments, a keyhole is installed on one side of the movable panel below the box body to lock and unlock the movable panel.

[0011] In some embodiments, a plurality of round holes are opened on the back of the box body.

[0012] The beneficial effect of the present application is that the existence of the spring makes the two ends of the movable panel always under the force of pushing outwards, so that the movable panel is always located at the midpoint of the axis of the rotating connection shaft. No matter which side the movable panel is pushed, the spring will always reset the movable panel, which makes the movable panel not rub against the box body during the rotation process, and eliminates the phenomena of paint peeling and difficult rotation of the box body caused by the rotation of the movable panel.

[0018] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of the present application.

[0019] In the embodiments of the present application, please refer to Figures 1 - 3 As shown, the present application provides a self-return mechanism for the panel of a delivery box, which mainly includes: a box body 1, on one side of which several openings 11 are provided; a rotating connection shaft 2, at both ends of which springs 21 are sleeved and a ring-shaped convex portion 22 is formed to abut against one end of the spring 21, and the rotating connection shaft 2 is rotatably arranged at both ends of the opening 11; a movable panel 3, rotatably arranged on the rotating connection shaft 2, and abutting surfaces 31 are formed at both ends of the movable panel 3 to be penetrated by the rotating connection shaft 2 and abutted by one end of the spring 21; the spring 21 is used to apply a force to both ends of the movable panel 3 outward at the same time to make the movable panel 3 automatically return to the central position.

[0020] Specifically, when the movable panel 3 rotates, the springs 21 at both ends of the rotating connection shaft 2 always abut against the movable panel 3, so that the movable panel 3 is always located at the midpoint position of the axis of the rotating connection shaft 2. Even if the movable panel 3 is subjected to a large force and applies force in the direction of one of the springs 21, after the force is stopped, the compressed spring 21 releases the force, making the movable panel 3 automatically return to the midpoint position of the axis of the rotating connection shaft 2, avoiding the possibility of paint peeling caused by direct contact between the movable panel 3 and the box body 1 to a certain extent.

[0021] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0022] Specifically, in order to enable non-owners of the delivery box to deliver letters on the premise that they cannot take out the letters inside the box body 1, one of the openings 11 or the openings 11 is a delivery port 111, the delivery port 111 is opened above the box body 1, and the rotating connection shaft 2 is horizontally arranged at the top of the delivery port 111.

[0023] More specifically, in order to enable the owner of the delivery box to take out the letters inside the box body 1, one of the openings 11 or the opening 11 is the pick-up opening 112, the pick-up opening 112 is opened at the front panel of the box body 1, and the rotation connection shaft 2 is longitudinally arranged on one side of the pick-up opening 112.

[0024] Furthermore, the opening 11 includes a delivery opening 111 and a pick-up opening 112. The delivery opening 111 is opened above the box body 1, and the pick-up opening 112 is opened below the box body 1. The first rotation connection shaft 2 is horizontally arranged, and the second rotation connection shaft 2 is longitudinally arranged. With such a setting, the delivery and pick-up actions of the delivery box are clearly distinguished, improving the work efficiency and preventing unauthorized persons from stealing letters.

[0025] Refer to Figure 1 As shown, in order to prevent unauthorized persons from stealing letters and ensure the use of the box body 1 by the mailbox owner, a keyhole 4 is installed on one side of the movable panel 3 below the box body 1 to lock and unlock the movable panel 3.

[0026] Preferably, a plurality of round holes 12 are opened on the back of the box body 1. Through these round holes 12, the box body 1 can be installed on a wall or a vertical plane, effectively utilizing the space.
