Detailed Description

The following detailed description of the embodiments of the present invention will be described with reference to the accompanying drawings, but the description of the embodiments by the applicant is not intended to limit the technical solutions, and any changes made according to the present invention rather than the essential changes should be considered as the protection scope of the present invention.

In the following description, all the concepts related to the directions or orientations of up, down, left, right, front and rear are based on the position shown in fig. 1, and thus, should not be interpreted as a specific limitation to the technical solution provided by the present invention.

Referring to fig. 1 and 2, the present invention relates to a portable trailer, which includes a base 1, a long rod 2, a clamping piece 3, a nut 4, a pressing screw 5, and a universal wheel 9, wherein the base 1 includes a hollow plate 11 and a groove 12 formed by sinking from the middle of the hollow plate 11 downward, the groove 12 may be a square groove or an arc groove, in this embodiment, the arc groove is preferably selected for placing round objects such as wheels, for example, wheels of an electric vehicle that have a tire burst, and the upper surface of the hollow plate 11 is used for placing objects with relatively flat bottoms, for example, a bag of grain crops, heavier equipment, etc.

Referring to fig. 1 to 3, two ends of the hollow plate 11 are respectively provided with long rods 2, two sides of each long rod 2 are respectively provided with a clamping piece 3, and two ends of each long rod 2, which are located at the outer sides of the two clamping pieces 3, are respectively provided with a rotatable nut 4 for preventing the clamping pieces 3 from falling off. Each clamping piece 3 is provided with a long groove 31. A compression screw 5 penetrates through the long groove 31 of the two clamping pieces 3 at each end of the hollow flat plate 11, the compression screw 5 can slide freely in the long groove 31, and the clamping pieces 3 can also slide downwards relative to the long rod 2 along the long groove 31. The pressing screw rod 5 passes through both ends of the elongated slot 31 to limit the distance between the two clamping pieces 3 by the fastening member and clamp the loaded object between the clamping pieces 3, and the specific positions of the pressing screw rod 5 and the clamping pieces 3 relative to the long rod 2 are determined by the shape of the loaded object. The fastening piece 3 is pressed by the fastening piece in three ways, the first way is: on both sides of the clamping screw 5, a clamping nut 6 is arranged for defining the distance between the two clamping blades 3, which method is not shown; the second method is as follows: one end of the compression screw 5 is provided with a fixing nut 7, the fixing nut 7 limits the corresponding clamping piece 3, but the fixing nut 7 cannot be screwed in or out along the compression screw 5 and can only be fixed at one end part of the compression screw 5, and the other end of the compression screw 5 is limited at the position corresponding to the clamping piece 3 by a compression nut 6 after penetrating through the elongated slots 31 on the two clamping pieces 3. In this method, the compression nut 6 is screwed in to clamp the clamping piece 3 against the loaded object, and is screwed out to loosen the clamping piece 3 from the loaded object, and then the loaded object is removed, which is shown in fig. 1. The third is: one end of the compression screw rod 5 is fixedly inserted with a pin 8, the pin 8 limits the corresponding clamping piece 3, and the other end of the compression screw rod 5 passes through the long grooves 31 on the two clamping pieces 3 and then limits the position of the corresponding clamping piece 3 by a compression nut 6. In this method, the compression nut 6 is screwed in to clamp the clamping piece 3 to the loaded object, and is screwed out to loosen the clamping piece 3 from the loaded object, and then the loaded object is removed, which is shown in fig. 2 and 3. The third method is simpler in structure and more convenient to install than the first and second methods, so the third method is preferred in this embodiment. The compression nut 6 comprises a first nut head 61 with a threaded hole in the middle and a first stop rod 62 which is formed by extending outwards from the first nut head 61 and is used for stopping the clamping piece 3, wherein the first stop rod 62 is provided with two first stop rods and extends towards two outer sides along the same central line of the first nut head 61. The middle of the first nut head 61 is a through threaded hole, so that the compression nut 6 can be screwed in and out along the compression screw 5. The fixing nut 7 includes a second nut head 71 having a threaded hole at a middle portion thereof and a second stopper 72 extending outward from the second nut head 71 to block the clamp piece 3, and the second stopper 72 has two pieces and extends outward along a same center line of the second nut head 71. The middle part of the second nut head 71 is a threaded hole with only one open end, so that the fixing nut 7 cannot be screwed in or out along the compression screw 5.

Referring to fig. 1 and 2, universal wheels 9 are arranged below the base 1, one, two or more universal wheels 9 are arranged at the lower ends of the hollow flat plate 11 according to the specification of the trailer, in this embodiment, the universal wheels 9 are arranged at the lower ends of the hollow flat plate, and the universal wheels 9 can rotate 360 degrees, so that great convenience is brought to the movement of the loaded object.

With continuing reference to fig. 1 to 3, the installation process of the portable trailer according to the present invention is as follows: when an object with a relatively flat bottom needs to be conveyed, the object is placed on the hollow flat plate 11 and is positioned between the four clamping pieces 3, then the compression screw 5 penetrates through the long grooves 31 on the two clamping pieces 3 at each end from the upper part of the object and is locked by the compression screw cap 6, each end of the loaded object is clamped between the two clamping pieces 3, finally the object is conveyed to a destination, and after the object reaches the destination, the compression screw cap 6 is screwed out to unload the goods. When a vehicle such as an electric vehicle is blown out, the blown-out wheel can be placed in the groove 12 of the trailer and positioned between the four clamping pieces 3, then the compression screw 5 penetrates through the long grooves on the two clamping pieces 3 at each end from the upper part of the wheel and is locked by the compression screw cap 6, each end of the loaded wheel is clamped between the two clamping pieces 3, finally the vehicle is pushed to a destination to replace the wheel, and the compression screw cap 6 is screwed out to dismount the wheel after the vehicle reaches the destination.
