Description

Technical Field

[0001] The utility model relates to the technical field of turnover boxes, and particularly relates to a protection component and a turnover box thereof. Background Technique

[0002] A turnover box, also known as a logistics box, is a container used for storing and transporting various items, especially designed to facilitate stacking and handling. It is widely used in multiple industries such as machinery, automobiles, household appliances, light industry, and electronics. It is not only used for the turnover and transportation of parts, but also for the storage and transportation of commodities such as food. In order to protect the sides of the existing turnover box from collision, sponge buffer blocks are usually glued at the corners of the box body. However, after long-term use, the surface of the sponge buffer blocks will be damaged, affecting their protective effect as the protection of the box body. Therefore, they need to be replaced in time. However, the adhesive used to bond the damaged sponge buffer blocks will remain on the surface of the box body, affecting the stability of the connection between the subsequently re-bonded sponge blocks and the box body. The glue and sponge debris need to be removed, which takes time. In order to achieve the quick replacement and fixation of the sponge buffer blocks, a new type of protection component and a turnover box are needed. Content of the Utility Model

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] The present utility model provides a protection component as Figures 1-3 shown, including a protection block 3, and a positioning block 5 is provided on the side of the protection block 3;

[0019] Specifically, a plurality of rectangular protrusions 502 are provided on the side of the positioning block 5, and the plurality of rectangular protrusions 502 are inserted and connected to the side of the protection block 3.

[0020] It should be noted that the protection block 3 is made of sponge material, and rectangular holes for inserting the rectangular protrusions 502 are provided on the side of the protection block 3. The protection block 3 and the positioning block 5 are bonded with glue; the rectangular protrusions 502 are used to increase the area of their contact surface, facilitating the fixation of the glue and enhancing the connection stability between the protection block 3 and the positioning block 5;

[0021] A connecting portion 4 is provided on the top of the positioning block 5;

[0022] Specifically, the connecting portion 4 includes a sleeve 401, a plug rod 402 is inserted and connected inside the sleeve 401, a movable column 403 is fixedly connected to the bottom of the plug rod 402, a plug block 404 is inserted and connected to the bottom side of the movable column 403, and the end of the plug block 404 is inserted and connected to the connection between the sleeve 401 and the positioning block 5;

[0023] It should be noted that the bottom end of the sleeve 401 is inserted into the top of the positioning block 5. A fixing groove 501 for inserting the sleeve 401 is provided on the top of the positioning block 5, and a semi-circular groove 5011 for inserting the plug block 404 is provided on the inner wall of the fixing groove 501;

[0024] Specifically, a through hole for inserting the plug block 404 is provided on the inner wall of the sleeve 401. The plug block 404 enters the semi-circular groove 5011 through this through hole. The top of the plug block 404 is inclined, facilitating its removal from the semi-circular groove 5011 to realize the unlocking of the sleeve 401 and the positioning block 5;

[0025] An activity groove 4031 for resetting the plug block 404 is provided on the side of the movable column 403, and an arc-shaped protrusion 4032 for extruding the plug block 404 is provided on the inner wall of the bottom of the activity groove 4031;

[0026] It should be noted that the arc-shaped protrusion 4032 facilitates the extrusion and fixation of the plug block 404 during the movement of the movable column 403, enabling it to insert into the semi-circular groove 5011 to realize locking. When the plug block 404 retracts into the activity groove 4031, its end completely disengages from the semi-circular groove 5011;

[0027] A resilience portion for driving the plug block 404 to lock is provided on the outer side of the plug rod 402 and inside the sleeve 401;

[0028] Specifically, the resilience portion includes a movable ring 405 and a compression spring 406. Both the movable ring 405 and the compression spring 406 are sleeved on the outer side of the plug rod 402, and the movable ring 405 is arranged on the top of the compression spring 406;

[0029] It should be noted that the movable ring 405 is adhesively fixed to the outer side of the insertion rod 402 with glue. The cross-sectional diameter of the top inner cavity of the sleeve 401 is larger than that of the bottom inner cavity. The diameter of the compression spring 406 is larger than the cross-sectional diameter of the bottom inner cavity of the sleeve 401. The movable ring 405 is in close contact with the inner wall of the sleeve 401, forming an extrusion on the compression spring 406.

[0030] A turnover box adopts the above-mentioned protection component, including a box body 1. An extension plate 2 is arranged at the top of the box body 1. The top end of the insertion rod 402 is inserted and connected to the bottom of the extension plate 2. The top of the sleeve 401 is fixedly connected to the bottom of the extension plate 2.

[0031] It should be noted that the extension plate 2 and the box body 1 are integrally injection-molded. A cylindrical hole for the insertion rod 402 to penetrate is opened at the bottom of the extension plate 2. The sleeve 401 and the extension plate 2 are adhesively fixed with glue.

[0032] During actual use, the user presses the insertion rod 402, causing the movable column 403 at the bottom of the insertion rod 402 to move downward in the sleeve 401, pulling down the protection block 3, so that the insertion block 404 in the semi-circular groove 5011 retracts into the movable groove 4031 in the sleeve 401, thereby disassembling the protection block 3. When the insertion rod 402 is released, the compression spring 406 outside the insertion rod 402 drives the movable column 403 to move upward through the movable ring 405, so as to extrude the insertion block 404 into the semi-circular groove 5011, locking the protection block 3 and the box body 1. Compared with directly adhesively bonding the protection block 3 to the side of the box body 1 with glue, this design facilitates the rapid replacement of the damaged protection block 3, avoids the process of removing glue on the outside of the box body 1 when the protection block 3 is adhesively removed with glue, and realizes the rapid replacement of the protection block 3.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
