The cargo vehicle compartment is open, and therefore requires shielding to protect the contents of the compartment. Existing masking systems for masking cargo vehicle compartments generally include a masking layer for masking the cargo vehicle compartment, the front end of the masking layer being connected to a front rim and the rear end of the masking layer being connected to a rear rim; the passenger side frame is arranged at the upper ends of the two side edges of the cargo carrying tool compartment, the two ends of the front frame are respectively fixed at the head of the passenger side frame and the head of the driving side frame, and the tail parts of the passenger side frame and the driving side frame are provided with fixing mechanisms. When the car is used, the rear frame edge is pulled backwards, the covering layer covers the car and fixes two ends of the front frame edge on the fixing mechanism. The general structure of the fixing mechanism is as follows: the tail parts of the driving side frame edge and the passenger side frame edge are respectively provided with a clamping seat, the clamping seat is provided with a clamping opening with a backward opening, the rear frame edge is provided with a clamping tongue, and the clamping tongue is clamped into the clamping opening.

Generally, the shielding structure of the rear end of the cargo carrying tool is divided into a hard shielding structure and a soft shielding structure, wherein the hard shielding structure adopts an integral casting technology, and the whole shielding structure is made of plastic or iron sheet. The soft shielding framework adopts the technology of coating the skin on the shielding framework, and the hard shielding framework in the prior art is formed by directly welding a plurality of steel pipes together, so that the welding is complicated, and the lower ends of the steel pipes are uneven and have gaps with a compartment.

At present, a cargo carrier in the market plays a role in closing a bucket by arranging a shielding on the bucket, the shielding needs the connection of a plurality of section bar frameworks which are vertical to each other, and the shielding is covered on the section bar frameworks, so that the whole shielding is formed, and a corner piece is needed to be in transition connection between two section bar frameworks which are vertical to each other.

A corner spare among the conventional art is whole injection moulding usually, and consumptive material and cost are great, are unfavorable for mass production, because the weight is great, if there is the clearance before corner spare and the fill, produce great noise easily at the in-process of traveling, and the hookup location setting of corner spare and body is on the bottom, leads to the connecting face unevenness of corner spare and body, is unfavorable for the assembly.

In order to eliminate the drawbacks of the conventional art, the applicant has previously proposed a modification, such as the patent document CN214499674U, disclosing a corner piece of a shelter that is easy to assemble, comprising a main body having two legs projecting perpendicularly thereon, characterized in that: the bottom of the main body is provided with a mounting seat, the mounting seat is provided with a cover body in a compact connection mode, the cover body and the main body are detachably connected, the end face of the cover body is flush with the end face of the bottom of the main body, and the cover body is detachably arranged in the mounting seat, so that the end face of the bottom of the cover body is flush with the end face of the bottom of the main body, and the corner piece is convenient to bond. Or as patent document CN214499675U, a shielded corner piece is disclosed, which comprises a main body, wherein the main body has at least two connecting end faces, the main body comprises a cavity arranged therein, a cover body is detachably arranged on the main body, the cover body is inserted into the main body along the plane of the cavity opening, and the cover body closes the cavity; still be equipped with sliding part and spacing portion on the lid, be equipped with the slide that supplies the sliding part to get into in the main part, just when the sliding part reaches the slide end, spacing portion and the fine and close spacing counterbalance of main part set up the cavity in the main part inside to realize the lightweight of corner spare.

The patent product does solve some defects existing in the traditional technology, but still has some product defects after being used. For example: 1. the dimensional accuracy of the product is not well controlled, and if the size of the slot is too small, the sliding part is not easy to insert into the sliding seat; if the size is too large, a gap exists after assembly, and the gasket is liable to shake and has poor sealing properties. 2. After the buckle is used for fastening, the product is not easy to split, and the product structure is usually required to be damaged when the product is forcibly disassembled. 3. When the buckle is buckled, the position precision and the pressing force are not easy to master, and the product is possibly deformed or even the buckle is broken due to slight deviation. 4. The bolt of fixed usefulness is squeezed into from the top down, and is unanimous with putting the direction when practical use under most scenes of product, consequently contacts outside impurity and rainwater more easily, leads to the bolt to change rusty, and impurity changes and permeates to the inner chamber through the bolt hole. 5. The mounting direction of the bolt is consistent with the up-and-down bumping direction of the vehicle during running, so that the bolt is more easily loosened during long-time use, and the assembly is not tight any more.
