In order to solve the technical problem, the utility model relates to a quick locking device of on-vehicle plastics rack, the plastics rack be the rectangle structure, have preceding, two sections that are parallel to each other in back be the base of "nearly" font, the interval is provided with the mounting hole on the outer hem of base bottom both sides, the left and right both sides of every base are equipped with the branch that the perpendicular upper portion that upwards extends has the external screw thread admittedly, and the width between two spinal branch poles in left and right both sides is greater than the width of plastics rack, the fixed cover in upper portion of every spinal branch are equipped with positioning spring, are equipped with on the spinal branch of every spinal branch left and right both sides to be located positioning spring top can follow the upper and lower gliding pressure frame of these two spinal branch poles, and the branch top spin that is located the pressure frame has the hand wheel.

As an improvement of the utility model, the utility model also comprises a rectangular base plate arranged on the front base and the back base, the length between the front end and the back end of the base plate is slightly larger than the length of the plastic cabinet, and the front end and the back end of the base plate respectively extend to the front side and the back side of the two bases.

Further, the front end of the base plate is provided with a folded edge which is bent downwards.

Furthermore, the left end and the right end of the base plate are provided with guide wall plates which are bent upwards, and the guide wall plates at the left end and the right end of the base plate are respectively welded on the supporting rods of the corresponding bases.

During the use, can with through installing the bolt in the mounting hole on preceding, two outer hem in back base both sides the utility model discloses fix on the vehicle body floor of vehicle, the plastics rack is lighter relatively, can be alone with the plastics rack from between the branch of the left and right both sides of base with plastics rack propelling movement to preceding, two back bases on, the rethread is rotatory the hand wheel will press the frame to compress tightly at the top of plastics rack, fix the plastics rack the utility model discloses it is interior, when the equipment needs maintenance in the plastics rack, rotate once more the hand wheel, make the pressure frame upwards slide, can be with plastics rack roll-off this moment the utility model discloses it is interior. After the base plates are arranged on the front base and the rear base, the support strength of the plastic cabinet can be improved, the plastic cabinet can be conveniently mounted and slid out, and the inner end of the plastic cabinet can be prevented from being inclined downwards in the pushing and sliding out processes; after the front end of the base plate is provided with the folded edge which is bent downwards, the base plate can be prevented from scratching operators when the plastic cabinet is pushed; after the left end and the right end of the base plate are provided with the guide wall plates which are bent upwards, the inner end of the plastic cabinet can be prevented from sliding leftwards and rightwards when the plastic cabinet is pushed, and the plastic cabinet can be conveniently installed.
