[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1 This embodiment includes a main frame 2, a pull rod 3, and a fixed rod 4. The pull rod 3 is installed in the main frame 2 and can be stretched and retracted. A single folding frame 5, a double folding frame 6, and a roller 7 are fixedly installed on the main frame 2. The fixed rod 4 is inserted into the single folding frame 5 and the double folding frame 6. Specifically, two single folding frames 5 are provided, and are fixedly installed on the left and right sides of the upper half of the main frame 2, respectively. The double folding frame 6 and the roller 7 are fixedly installed on the left and right sides of the lower half of the main frame 2, respectively.

[0027] Reference Figure 1 and Figure 2 The single folding frame 5 includes two folding seats 51 and two support rods 52. The support rods 52 are fixedly mounted on the folding seats 51, and the folding seats 51 are fixedly mounted on the main bracket 2. At the same time, the folding seats 51 and the support rods 52 correspond one to one, and the two folding seats 51 of the single folding frame 5 are fixed on the left and right sides of one side of the main bracket 2, one on the left and one on the right.

[0028] Reference Figure 1 and Figure 3 The folding seat 51 includes a fixed seat 511, a rotating seat 512, a movable shaft 513, a pressing button 514 and a return spring 515. The fixed seat 511 is fixedly installed, and the rotating seat 512 is hinged to the fixed seat 511. The support rod 52 is fixedly installed on the rotating seat 512. The support rod 52 has a fixing hole 521. The wire drum 1 has a through hole 11. The fixing rod 4 passes through the through hole 11 and is simultaneously plugged into the fixing holes 521 of the two support rods 52, thereby achieving the fixation of the wire drum 1. The wire drum 1 will not shake when pulling the transport vehicle, and after transporting to the destination, the support rod 52 can be folded up by the rotating seat 512. Whether pulling the transport vehicle again or folding the transport vehicle, the space occupied is greatly reduced.

[0029] Reference Figure 1 and Figure 3Specifically, the rotating seat 512 has a groove for placing the movable shaft 513 and a through hole for the pressing button 514 to pass through, that is, the rotating seat 512 has a groove on one side and a through hole on the other side, and the fixed seat 511 has an arc groove 5111 for the pressing button 514 to move. The pressing button 514 has a microhole corresponding to the radius of the movable shaft 513 on the side facing the movable shaft 513, and one side of the movable shaft 513 is located in the microhole and slides, and the other side is located in the groove. At the same time, the movable shaft 513 is located in the microhole and the groove to limit the movable shaft 513, and the return spring 515 is sleeved on the outer circumferential surface of the movable shaft 513. , and one end of the return spring 515 abuts against the surface of the rotating seat 512, and the other end abuts against the pressing button 514, that is, pressing the return spring 515 will compress the return spring 515; the pressing button 514 includes a pressing head 5141, a movable section 5142 and a locking section 5143, and the arc groove 5111 includes a locking groove 5112 and a movable arc groove 5113. The radii of the locking section 5143, the locking groove 5112 and the through hole on the rotating seat 512 are all the same, the radii of the movable section 5142 and the movable arc groove 5113 are the same, and the center of the movable arc groove 5113 is located at the hinge point between the rotating seat 512 and the fixed seat 511.

[0030] When the pressing head 5141 is pressed to disengage the locking section 5143 from the locking groove 5112, the return spring 515 is compressed, the locking section 5143 disengages from the locking groove 5112, and the movable section 5142 enters the locking groove 5112, and the movable section 5142 can move in the movable arc groove 5113, thereby realizing relative rotation of the rotating seat 512 and the fixed seat 511; when the pressing button 514 is reset under the elastic force of the return spring 515, the locking section 5143 is reset to the locking groove 5112, the movable section 5142 cannot move, and the rotating seat 512 and the fixed seat 511 can be locked relative to each other.

[0031] Reference Figure 1 and Figure 2 In addition, the double folding frame 6 is actually composed of two single folding frames 5. The fixing base 511 of one single folding frame 5 is fixedly mounted on the support rod 52 of the other single folding frame 5, and the folding rotation direction of the support rod 52 is toward the main frame 2. At the same time, the single folding support rod 52 of the double folding frame 6 fixed to the main frame 2 does not have a fixing hole 521. Therefore, even though the double folding frame 6 is composed of two single folding frames 5, it can only carry one wire drum 1.

[0032] Reference Figure 1 and Figure 2The roller 7 includes a connecting frame 71, a wheel frame 72 and three tires 73. The connecting frame 71 is fixed to the main bracket 2, and the wheel frame 72 is rotatably connected to the connecting frame 71. The tires 73 are evenly installed and distributed in a circle around the center of the wheel frame 72. When pulling the transport vehicle up the stairs, the steps can be climbed by rotating the tires 73 around the wheel frame 72, so that even if the transport vehicle carries the wire drum 1 and causes the weight to increase, the transport vehicle can be easily pulled up the stairs, which is more labor-saving.

[0033] Reference Figure 1 and Figure 4 Furthermore, two symmetrical limiting rods 21 are disposed within a horizontal round rod of the main bracket 2. Each limiting rod 21 has a shifting block 211, and the main bracket 2 has a shifting slot 22 for moving the shifting block 211. The shifting block 211 extends from the interior of the main bracket 2 through the shifting slot 22. A limiting spring 23 is disposed between the two limiting rods 21. Under the elastic force of the limiting spring 23, the limiting rod 21 abuts the pull rod 3. By moving the shifting blocks 211, the two shifting blocks 211 approach each other and no longer abut the pull rod 3. The limiting spring 23 is compressed, allowing the pull rod 3 to freely expand or contract. Finally, the shifting blocks 211 are released, and under the action of the limiting spring 23, the shifting blocks 211 re-abut the pull rod 3. In this embodiment, the pull rod 3 has a limiting groove for the limiting rod 21 to limit the position, so that the limiting rod 21 can be firmly fixed. At the same time, the pull rod 3 also has a hole that has the same function as the fixing hole 521 on the support rod 52. The fixing rod 4 can also be inserted into the hole. The hole is only exposed after the pull rod 3 is stretched out. Therefore, the transport vehicle can carry a maximum of four wire drums 1. In this embodiment, the fixing method is welding or bolting.
