Patent Application
20100212248
The present application claims a priority to Chinese patent application No. 200920009963.2 filed on Feb. 20, 2009, which is herein incorporated by reference in entirety thereof.
The present invention relates to a connector for connecting an outer plate of side panels and an outer corner post of a container body of a refrigerated and thermal container or a van, and a container body structure of a refrigerated and thermal vehicle.
Current container body of an aluminum refrigerated or thermal semi-trailer, or a refrigerated or thermal freight container comprises a floor, a front wall mounted on the floor, a rear door frame with a rear door, a left side panel, and a right side panel. Since the two side panels, the front wall or the rear door frame themselves are mostly connected with a mechanical automatic riveting process, the rivet has good formation and does not easily loosen and does not easily leak water. However, since the connection between components is just performed by a manual riveter, there is a problem that the rivet herein has a bad formation, easily loosens, makes the connection unsecure, and affects the appearance. In particular, at the places where the front end and the rear end of the outer plate are connected with the front corner post and the rear corner post, such problem is most prominent. The side panels as a structure of the container body of a refrigerated semi-trailer or refrigerated freight container comprises an outer plate, an inner plate and a heat preservation layer clamped between the outer plate and the inner plate. Since a few retention plate phenomena will exist during the manufacture of the side panels, the pressure from a foaming mass during foaming process will cause the excessive deformation amount of the plates to release towards the open front or rear end of the side panels. Therefore, corrugated deformation most easily occurs at the front or rear end portion of the side panels. When the corrugated side panels are connected via rivets with the front corner post or the rear door corner post during assembling, the appearance is very poor, the connection is not secure, and thus heat preservation effect of the freight container will be affected.
An object of the present invention is to provide a connector for connecting an outer plate of side panels and an outer corner post of a container body which may realize a firmly connection and have good appearance with respect to the above deficiencies in the prior art.
Another object of the present invention is to provide a container body of a refrigerated and thermal vehicle which has a good heat preservation effect with respect to the above deficiencies in the prior art.
In order to attain the above objects, the following technical solutions may be adopted according to the present invention.
According to the present invention, a connector for connecting an outer plate of side panels and an outer corner post of a container body may comprise: a connecting plate for connecting the outer plate and the outer corner post of the container body, perpendicularly provided with a strengthening stop plate at an inner side of a middle portion thereof, perpendicularly provided with a stop groove for receiving the outer plate at an outer side of the middle portion thereof, and provided with a seat plate in parallel with a base plate of the stop groove at an end thereof connecting the outer corner post, wherein two clipping strips are symmetrically provided on opposite sides of the seat plate and the base plate of the stop groove; and a cover plate provided with two elastic clipping strips which respectively engage with the two clipping strips and have a hook-shape cross section.
The strengthening stop plate may have an L-shape cross section.
The connecting plate may be provided with a strengthening rid at the end thereof connecting the outer plate.
According to the present invention, a container body of a refrigerated and thermal vehicle may comprise a connector for connecting an outer plate of side panels and an outer corner post. The connector may comprise: a connecting plate for connecting the outer plate and the outer corner post of the container body, perpendicularly provided with a strengthening stop plate at an inner side of a middle portion thereof, perpendicularly provided with a stop groove for receiving the outer plate at an outer side of the middle portion thereof, and provided with a seat plate in parallel with a base plate of the stop groove at an end thereof connecting the outer corner post, wherein two clipping strips are symmetrically provided on opposite sides of the seat plate and the base plate of the stop groove; and a cover plate provided with two elastic clipping strips which respectively engage with the two clipping strips and have a hook-shape cross section.
The advantages and the positive effects according to the connector for connecting the outer plate of side panels and the outer corner post of the container body are as follows. In the present invention, since the stop groove capable of blocking the outer plate and the strengthening plate capable of blocking most of the foaming material in the heat preservation layer of side panels are provided, the ends of the side panels almost become into a closed state, and corrugated deformation does not easily occur, and thus the connecting strength at this position is not affected. Therefore, through the connector of the present invention, the connection between the outer plate of side panels and the front wall corner post or the rear door frame corner post is very secure, and has a good appearance. Moreover, the connector of the present invention is also provided with the cover plate capable of being inlaid onto the connecting plate, so that the connecting rivet does not easily fall out, which further assures the connecting strength and may effectively prevent corrosion of the connecting rivet and may be beneficial to extend the service life.
The advantages and the positive effects according to the container body of the refrigerated and thermal vehicle of the present invention are as follows. Since the container body employs the connector for connecting the outer plate of side panels and the outer corner post according to the present invention, not only the connection is secure but also air tightness is good, which may effectively prevent heat exchange between inside and outside of the container body and thus heat preservation effect is good.
The above and other objects, features and advantages will be more apparent by way of the following description of preferred embodiments with reference to the drawings.
The relevant reference numbers are explained as follows. Herein, the reference number 1 indicates an outer plate, the reference number 3 indicates a connecting plate, the reference number 4 indicates a stop groove, the reference number 5 indicates a strengthening stop plate, the reference number 6 indicates a seat plate, the reference number 7 indicates clipping strips, the reference number 8 indicates a cover plate, the reference number 9 indicates elastic clipping strips, the reference number 10 indicates a strengthening rib, the reference number 11 indicates a solid rivet, the reference number 12 indicates a front wall outer corner post, the reference number 13 indicates a rivet, and the reference number 14 indicates a rear door frame corner post.
