[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] like Figure 1 As shown, the utility model discloses a hand strap structure of an insulated box, comprising a box body 1 and a box cover 2, at least two opposite side walls of the upper end of the box body 1 extend outward to form a boss 3, and mounting holes 8 with a larger upper part and a smaller lower part are arranged at both ends of the boss 3, and the mounting hole 8 passes through the boss 3, and also comprises a hand strap 4, and the two ends of the hand strap 4 are bent and fixed to form an annular sleeve structure 10, and the annular sleeve structure 10 of the hand strap 4 passes upward from the bottom of the mounting hole 8, and a limiting short shaft 9 is arranged in the annular sleeve structure 10, and the limiting short shaft 9 and the annular sleeve structure 10 are clamped in the mounting hole 8, and the diameter of the limiting short shaft 9 is larger than the minimum width of the lower end of the mounting hole 8.

[0016] The upper end of the box body 1 can extend outward to form a boss 3. Of course, the boss 3 can be extended only to the two side walls where the mounting hole 8 is required, or the boss 3 can be extended all around the box body 1 to form an annular structure, which has stronger integrity. The box cover 2 is connected to the box body 1 by hinges, pins, etc., and is locked by a lock. This structure is a known technology and will not be repeated here, nor will it be limited in any way. A through mounting hole 8 is provided on the boss 3, and the mounting hole 8 is in the form of a large upper and small lower part. The hand strap 4 is generally woven with fabric to form a flat belt structure, and its end is bent and fixed to form an annular sleeve structure 10, so it can pass from the mounting hole 8 from bottom to top, and after passing through the mounting hole 8, a limiting short shaft 9 is inserted into the annular sleeve structure 10, and it is clamped in the mounting hole 8, so that the hand strap 4 is fixed in the mounting hole 8, and the hand cannot be lifted and pulled out of the mounting hole 8, and the firmness is high. This form is easy to install and has high firmness. During use, the hand strap 4 passes around the boss 3 and then moves upward, so that the hand strap 4 in the mounting hole 8 is subjected to downward tension, so that it will become tighter and tighter and will not become loose.

[0017] With this installation structure of the hand strap 4, if the hand strap 4 is worn or broken after long-term use, the limiting short shaft 9 can be withdrawn upward from the installation hole 8, thereby realizing replacement of the hand strap 4, which is easy to operate and improves the service life of the insulation box.

[0018] The mounting hole 8 is a stepped hole, which is composed of two rectangular holes of the same length and different widths, and the connection between the two rectangular holes is rounded. In order to make the limiting short shaft 9 more stable in the mounting hole 8, the mounting hole 8 is a stepped hole, so that the width of the rectangular hole at the upper end is close to or slightly larger than the diameter of the limiting short shaft 9, and the length can be slightly larger than the length of the limiting short shaft 9. In this way, after installation, when the annular sleeve structure 10 of the hand strap 4 is covered on the limiting short shaft 9, the overall diameter will be slightly larger than the width of the rectangular hole, but it has a certain compression capacity, so it can be pressed into the mounting hole 8 to achieve interference fit, and the connection is more firm and stable. The width of the rectangular hole at the bottom must be smaller than the diameter of the limiting short shaft 9 to prevent the limiting short shaft 9 from sliding out from the bottom, so the installation of the hand strap 4 is firm and stable.

[0019] The middle part of the hand strap 4 is covered with a plastic body to form a connecting shaft 5, and a handle 6 is sleeved on the connecting shaft 5, and the handle 6 is provided with an anti-skid pattern 7. In order to improve the comfort of the hand strap 4 during use, a plastic body is used to cover the middle part of the hand strap 4 to form a connecting shaft 5, which has high overall strength, and the handle 6 is covered on the outside. The handle 6 can rotate relative to the connecting shaft 5, which is not easy to cause friction to the hand. The anti-skid pattern 7 can improve the gripping ability, and the specific form of the anti-skid pattern 7 is not limited.
