[0018] The utility model will be further described below in combination with the drawings:

[0019] Refer to the attached drawings Figures 1-5 : In this embodiment, a high-strength luggage pull rod includes a crossbar 3, a rubber sleeve 5, and a box body 6. The middle part of the outer wall of the crossbar 3 is fixedly connected with the rubber sleeve 5. The inner wall of the crossbar 3 is fixedly connected with a reinforcing rib 4. The reinforcing rib 4 is made of magnesium alloy material. Magnesium alloy has high strength properties and is used for super-light luggage pull rod. The reinforcing rib 4 is in a net-like three-star hole shape, further improving the strength of the crossbar 3.

[0020] The lower end of the outer wall of the crossbar 3 is provided with a luggage pull rod support structure 1. The inner wall of the front side of the box body 6 is fixedly connected with two sleeves 2. The lower end of the plurality of second sliding rods 105 is fixedly connected with the sleeves 2. The outer wall of the upper end of the first sliding rod 101 is movably connected with the sleeves 2 and the box body 6. The first sliding rod 101 can move in the sleeves 2 and the box body 6. The lower end of the outer wall of the box body 6 is provided with four universal wheels.

[0021] Refer to the attached drawings Figures 1-4 : The luggage pull rod support structure 1 includes a first sliding rod 101. The lower end of the outer wall of the two first sliding rods 101 is fixedly connected with two cross plates 102. The cross plates 102 can only slide upwardly under the limitation of the second sliding rods 105. The inner wall of the cross plates 102 is slidably connected with a clamping block 104. The clamping block 104 can move in the sliding groove processed in the inner wall of the cross plates 102. The inner wall of the cross plates 102 is provided with a spring 103. The spring force coefficient of the spring 103 can be determined according to actual needs to meet the working needs. The two ends of the spring 103 are fixedly connected with the clamping block 104 and the cross plates 102, respectively. The outer wall of the clamping block 104 is in abutment with the plurality of second sliding rods 105. The outer wall of the second sliding rod 105 is processed with a plurality of clamping grooves.

[0022] Working principle:

[0023] High-strength luggage pull rod support work:

[0024] When the pull rod of the luggage needs to be used to drag the luggage to move or carry, the luggage pull rod is composed of the crossbar 3, the rubber sleeve 5, and the first sliding rod 101. The user pulls the crossbar 3 upwardly by holding the rubber sleeve 5. The crossbar 3 is fixedly connected with the reinforcing rib 4 inside. The reinforcing rib 4 is made of magnesium alloy material. Magnesium alloy has high strength properties and is used for super-light luggage pull rod. The reinforcing rib 4 is in a net-like three-star hole shape, further improving the strength of the crossbar 3.

[0025] The horizontal rod 3 drives two first slide rods 101 to move upward, the first slide rod 101 drives the lower end horizontal plate 102 to slide upward on the outer wall of the second slide rod 105, the horizontal plate 102 is limited to slide upward by the second slide rod 105, at this time, the clamping block 104 in the horizontal plate 102 is forced to move inward and extrude the spring 103, so that the clamping block 104 is separated from the clamping groove at the lower end of the outer wall of the second slide rod 105, the clamping block 104 moves upward with the horizontal plate 102, when the clamping block 102 corresponds to the upper end of the second slide rod 105, the clamping block 104 is driven to move outward by the spring 103 and is clamped into the corresponding clamping groove of the second slide rod 105;

[0026] Since the outer wall of the second slide rod 105 is provided with a plurality of clamping grooves, the pull rod can be limited in height by the clamping block 104, so that the pull rod can be pulled out and dragged to move the bag, since a plurality of universal wheels are installed at the lower end of the bag 6 for movement, so that a large pulling force is not required during the pulling process of the bag, the clamping block 104 is prevented from moving, and a plurality of horizontal plates 102 are arranged at the lower end of the first slide rod 101, so that the first slide rod 101 can be supported at multiple positions, thereby effectively improving the stability of the pull rod during use, avoiding the phenomenon that the pull rod and the sleeve are loose at the telescopic position and are easily deformed and stuck under force after the pull rod is pulled out in the prior art, thereby making the pull rod more stable and improving the strength of the pull rod.

[0027] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes can be made in form and details within the scope of the claims.
