Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boxes, in particular to a thermal insulation box shoulder strap assembly structure. Background Art

[0002] In order to achieve the heat preservation effect, the box assembly of the heat preservation box generally has an inner box, a heat preservation layer and an outer box. In the prior art, the shoulder strap and the box assembly are generally connected by a riveting structure, that is, a rivet is set at each end of the shoulder strap, which penetrates the inner box, the heat preservation layer and the outer box in sequence to achieve the connection between the shoulder strap and the box assembly. With this connection method, the end of the rivet penetrates the inner box, which affects the appearance of the inner box. At the same time, since the heat preservation layer is penetrated by the rivet, the overall structure of the heat preservation layer is damaged, reducing the heat preservation effect of the heat preservation box. In addition, since only one rivet is set at both ends of the shoulder strap assembly, when lifting the heat preservation box, the force at the connection between the rivet and the box assembly is relatively concentrated, which is easy to cause damage to the box assembly, and the overall structural stability of the heat preservation box is poor.

The fixing plate 4 is attached to the inner wall of the outer box 11, and the base 3 is fixed to the outer box 11 via the fixing plate 4. Specifically, in order to avoid the concentration of force at the connection between the box assembly 1 and the shoulder strap assembly 2 when the incubator box is lifted, thereby damaging the structure of the incubator box, refer to Figure 2 , Figure 3, the side wall of the base 3 close to the outer box body 11 is evenly distributed with at least two connecting columns 31. In this embodiment, the number of connecting columns 31 is 3, which can be adjusted according to the actual force conditions. At the same time, the side wall of the outer box body 11 is provided with through holes corresponding to the positions of the connecting columns 31 and the same number, and the connecting columns 31 are penetrated in the through holes. The fixing plate 4 is provided with fixing holes corresponding to the positions of the connecting columns 31 and the same number on the side wall close to the outer box body 11, and the fixing holes are penetrated with screws for locking screws 5 for threaded connection with the connecting columns 31. In this embodiment, only through holes are provided on the outer box body 11, which does not damage the structure of the inner box body 12 and the insulation layer, ensures the aesthetics of the inner box body 12, and at the same time, improves the insulation effect of the insulation box.

[0025] Further, in order to facilitate the active connection between the base 3 and the shoulder strap assembly 2, in this embodiment, refer to Figure 3 A first protrusion 32 is provided on the side wall of the base 3 away from the outer box body 11. The first protrusion 32 is provided with a connection hole in the radial direction. A first connection ring 33 is inserted into the connection hole. The first connection ring 33 is movably connected to the buckle 23 on the shoulder strap assembly 2. Furthermore, in some embodiments, in order to simplify the overall structure of the base 3 and facilitate the processing of the base 3, the first protrusion 32 is fixedly connected to the base 3. In addition, in some other embodiments, in order to facilitate the adjustment of the shoulder strap assembly 2 during use, the first protrusion 32 is rotatably connected to the base 3, and specifically, riveting can be adopted.

Furthermore, in order to facilitate the adjustment of the length of the shoulder strap body 21, in the present embodiment, both ends of the shoulder strap body 21 are provided with a snap-on protrusion 211, and the shoulder strap body 21 is provided with a snap-on hole 212 corresponding to the snap-on protrusion 211, and the shoulder strap body 21 is also provided with a connecting sleeve 213 outside the shoulder strap body 21, and the connecting sleeve 213 limits the end of the folded shoulder strap body 21. Specifically, in the present embodiment, there are two ways to adjust the length of the shoulder strap body 21. When the incubator needs to be carried on the shoulder, the adjustment method refers to Figure 3, the two ends of the shoulder strap body 21 are partially folded, so that the clamping bosses at both ends of the shoulder strap body 21 are respectively clamped in the corresponding clamping holes 212 at the two ends. This adjustment method makes the shoulder strap body 21 longer and suitable for shoulder carrying. When the incubator needs to be carried by hand, refer to the adjustment method Figure 4 , fold the shoulder strap body 21 in half, and insert the clamping boss at one end of the shoulder strap body 21 into the clamping hole 212 at the other end. This adjustment method makes the shoulder strap body 21 shorter and suitable for hand-carrying. The length of the shoulder strap body 21 can be adjusted accordingly according to actual use requirements, and the adjustment is flexible. Furthermore, in order to prevent the shoulder strap body from strangling the skin, a protective sheath 24 is also provided in the middle of the shoulder strap body.

[0028] Furthermore, in order to prevent the locking screw 5 from loosening during transportation, the head of the locking screw 5 may rub against the side wall of the insulation layer and damage the insulation layer. Therefore, in this embodiment, refer to Figure 5 , a silicone gasket 6 is provided on the side wall of the fixing plate 4 close to the insulation layer. Specifically, the silicone gasket 6 can be directly fixed to the fixing plate 4 by gluing. Furthermore, in order to prevent the head of the locking screw 5 from protruding and the head of the locking screw 5 from interfering with the insulation layer when installing the insulation layer, in this embodiment, the locking screw 5 is a countersunk screw, and the end face of the head of the locking screw 5 is kept flush with the end face of the fixing plate 4.

[0029] The assembly process of the utility model is as follows: first, the connecting column 31 on the base 3 is inserted into the through hole on the outer box body 11, the fixing plate 4 and the base 3 are fixed by the locking screw 5, and then the insulation layer and the inner box body 12 are installed and the shoulder strap assembly 2 and the base 3 are connected.
