Description

Technical Field

[0001] The utility model relates to the technical field of cargo box door panels, and in particular to an auxiliary opening and closing device for a cargo box side door panel. Background Art

[0002] A truck is a commercial vehicle designed and equipped primarily for the transportation of goods. It can tow a trailer or not. A truck is generally called a van, also known as a truck. It refers to a car that is primarily used to transport goods. Sometimes it also refers to a car that can tow other vehicles. It belongs to the category of commercial vehicles and can generally be divided into heavy and light types according to the weight of the vehicle. Most trucks use diesel engines as their power source, but some light trucks use gasoline, LPG or natural gas. Different types of trucks have different sizes of cargo boxes because they load different types of goods. Generally, the cargo box doors are opened manually.

[0003] At present, some trucks with side-opening door panels are inconvenient to open during use due to the loading of different types of goods, the deformation of the cargo box over time, and the high height of the cargo box. Such problems seriously restrict the convenience of using the vehicle, increase operation time, reduce attendance efficiency, and pose safety hazards. Therefore, we propose a new type of cargo box side-opening door panel opening and closing auxiliary device. Utility Model Content

[0030] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0033] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0034] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0035] like Figure 1-3 The shown device is a cargo box side door panel opening and closing auxiliary device, comprising a base plate 1, a door panel 2 is hingedly connected to the right side of the base plate 1, a sealing gasket 3 is fixedly installed on the right side of the door panel 2, a fixed plate 4 is arranged on the right side of the sealing gasket 3, a movable plate 5 is rotatably connected to the outer side of the door panel 2, a positioning cylinder 6 is welded to the right side of the movable plate 5, a mounting plate 7 is fixedly installed on the outer side of the fixed plate 4, a first limiting ring 8 and a second limiting ring 9 are welded to the outer side of the mounting plate 7 in sequence from top to bottom, an insert rod 10 is inserted inside the second limiting ring 9, a rotating cylinder 11 is fixedly installed at the lower right corner of the outer side of the door panel 2, a handle 12 is rotatably connected to the inner side of the rotating cylinder 11, an anti-slip cylinder 13 is sleeved on the outer side of the handle 12, a right-angle block 14 is arranged directly below the door panel 2, and a lifting rod 15 is fixedly installed on the outer side of the insert rod 10.

[0036] Specifically, the sealing gasket 3 is made of rubber material. The sealing gasket 3 made of rubber material has toughness and can be deformed to a certain extent when the door panel 2 is closed, so as to facilitate sealing of the truck compartment.

[0037] See also Figure 1-3 The insertion rod 10 passes through the first limiting ring 8 and the second limiting ring 9, wherein the lifting rod 15 is located between the first limiting ring 8 and the second limiting ring 9. By using the first limiting ring 8, the second limiting ring 9 and the lifting rod 15 in cooperation with each other, the insertion rod 10 can be limited so that the insertion rod 10 can be movably installed in the first limiting ring 8 and the second limiting ring 9.

[0038] In this solution, the handle 12 is formed by bending round steel or round tube, and there are no restrictive requirements on specifications and models. The handle 12 made by one-piece molding has the characteristics of high hardness and is not easy to deform, which is convenient for daily use.

[0039] Preferably, the anti-skid tube 13 is made of sponge material. The anti-skid tube 13 made of sponge material can increase the friction with the hand, improve its grip, and at the same time improve the user's feeling of use, that is, the gripping feeling.

[0040] Specifically, the right-angle block 14 is fixedly installed at the lower right corner of the base plate 1. The right-angle block 14 can limit the door panel to a certain extent, ensuring that the door panel does not deviate to a large extent and can be used normally.

[0041] Specifically, the diameter of the insertion rod 10 is smaller than the inner diameter of the positioning tube 6 . By setting the diameter of the insertion rod 10 to be smaller than the inner diameter of the positioning tube 6 , the insertion rod 10 can be quickly inserted into the positioning tube 6 .

[0042] The working principle of the utility model is: when it is necessary to close the truck cargo box door panel 2, directly rotate the door panel 2, hold the handle 12 by hand to adjust the position of the door panel 2, so that the door panel 2 is flush with the fixed plate 4, and the sealing gasket 3 can achieve a certain degree of sealing for the cargo box, and then rotate the movable plate 5 to make the positioning tube 6 located directly below the insertion rod 10, and then manually move the insertion rod 10, under the action of the first limiting ring 8 and the second limiting ring 9, the insertion rod 10 is inserted into the positioning tube 6 to complete the closing of the door panel 2. When it is necessary to open the truck cargo box door panel 2, directly hold the lifting rod 15 and move the insertion rod 10 upwards so that the insertion rod 10 is separated from the positioning tube 6. At this time, pull out the handle 12 by hand, rotate the door panel 2 outward, and the door panel 2 can be opened.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
