The fixed guardrails 2 include a front guardrail 2-1, a left guardrail 2-2, and a right guardrail 2-3, which are fixedly installed at the front, left, and right sides of the cargo platform 1, respectively, to limit the cargo's movement in the front, left, and right directions. The movable locking guardrail 3 is movably installed at the rear end of the cargo platform 1. All three guardrails (front, left, and right) are vertically arranged.

[0024] like Figure 2 As shown, the movable locking guardrail 3 includes a locking mechanism 3-1, a guardrail body 3-2, and pins 3-3. The guardrail body 3-2 is movably installed at both ends of the rear left and right sides of the loading platform 1 via pins 3-3, thus connecting to the loading platform 1. The guardrail body 3-2 has a locking mechanism 3-1 in the middle for vertically or horizontally installing itself on the loading platform 1. When the movable locking guardrail 3 is erected (i.e., vertically placed) and locked, it works in conjunction with the binding ropes 4 to limit and fix the goods during transportation, preventing them from being bumped, falling, or damaged. When the movable locking guardrail 3 is horizontally positioned, it is flush with the surface of the loading platform 1, facilitating loading and unloading of goods and the loading of extra-long goods.

[0025] like Figure 3 As shown, the locking mechanism 3-1 includes a fixed cover 3-1-1, a spring 3-1-2, a locking pin 3-1-3, a handle 3-1-4, an outer cover 3-1-5, and a lock hole seat 3-1-6. The lock hole seat 3-1-6 is welded and fixed to the middle of the rear end of the cargo platform 1. A lock hole is provided on the lock hole seat 3-1-6. The fixed cover 3-1-1 is located in the middle of the guardrail body 3-2 and is welded and fixed to the guardrail body 3-2. An outer cover 3-1-5 is provided below the fixed cover 3-1-1. A locking pin 3-1-3 is provided between the fixed cover 3-1-1 and the outer cover 3-1-5. A spring 3-1-2 is provided between the locking pin 3-1-3 and the fixed cover 3-1-1. The upper concave circular hole of the locking pin 3-1-3 realizes the spring 3-1-2. The lower end of the 1-2 is limited, and the lower part of the fixed cover 3-1-1 is recessed to limit the upper end of the spring 3-1-2. The middle of the locking pin 3-1-3 has a transverse through hole, and the handle 3-1-4 is placed in the transverse through hole and welded and fixed. The lower part of the locking pin 3-1-3 has a pin 3-3 extending outward. The bottom of the outer cover 3-1-5 is provided with a round hole to ensure that the pin 3-3 extends outward. The two sides of the fixed cover 3-1-1 and the two sides of the outer cover 3-1-5 are designed with guide rail grooves of equal width to ensure that the handle 3-1-4 extends outward and moves radially along the guide rail groove. After the fixed cover 3-1-1 is fitted with the spring 3-1-2, the locking pin 3-1-3 and the handle 3-1-4, the outer cover 3-1-5 is assembled with the fixed cover 3-1-1 and welded and fixed to form the locking mechanism 3-1.

[0026] The cargo platform 1 has a reserved hole 5 at the lower middle of the rear end, which is used to insert the pin 3-3 to lock the movable locking guardrail 3 when it is laid down horizontally.

[0027] like Figures 4-6 As shown, the working process of this utility model is as follows: When unloading, release the binding rope 4, operate the locking mechanism 3-1 to unlock and rotate the movable locking guardrail 3, that is, the operator pulls the handle 3-1-4 with his finger, driving the locking pin 3-1-3 to move upward, so that the pin 3-3 disengages from the lock hole of the lock hole seat 3-1-6 to unlock; after unlocking, rotate the movable locking guardrail 3, and when it is level with the height of the loading platform 1, release the finger. Under the action of the spring 3-1-2, the locking pin 3-1-3 returns to its original position, and the pin 3-3 is inserted into the reserved hole 5 at the tail of the loading platform 1 to achieve folding and locking, which facilitates the unloading of goods. When reloading, if the goods exceed the length of the loading platform 1, the movable locking guardrail 3 can act as a support to support the excess part of the goods, and the goods can be tied and fixed by the binding rope 4. If the cargo is not too long, pull the handle 3-1-4 to unlock it, rotate the movable locking guardrail 3 until it is perpendicular to the cargo platform 1, release the handle 3-1-4, and the locking pin 3-1-3 will be inserted into the locking hole of the lock hole seat 3-1-6 to lock it. This process can be repeated in a cycle.
