[0031] Reference Figures 1 to 4 As shown in the drawings, the embodiment specifically discloses a back frame for small unit, which is used for carrying the small unit 10, and the back frame comprises a back plate 1 and a fastening belt 2.

[0032] In the illustrated embodiment, the upper connecting piece 3 is provided with two parts, which are symmetrically distributed on the upper side of the back plate 1, and the upper connecting piece 3 comprises a first connecting plate 31 fixedly connected with the back plate 1, a horizontal plate 32 connected with the first connecting plate 31 perpendicularly and parallel to the back plate 1, and a flange 33 formed by bending outward from the end of the horizontal plate 32, and the flange 33 is provided with a connecting hole 34; the two ends of the fastening belt 2 are connected with the corresponding connecting holes 34 on the two sides respectively, so as to fix the upper part of the unit, the connecting hole 34 is in the shape of a strip hole, and the inner arc is transitioned, so as to facilitate the passing of the fastening belt 2.

[0033] The lower connecting piece 4 is provided with at least two parts, which can ensure the overall stability when the unit is placed, and the lower connecting piece 4 is located at the lower end of the upper connecting piece 3, and the lower connecting piece 4 comprises a second connecting plate 41 fixedly connected with the back plate 1, and the bottom of the second connecting plate 41 is connected with a hook 42, which can be used to hook the horizontal pipe at the lower end of the rack.

[0034] It can be understood that a shoulder strap (not shown in the drawings) is further arranged on the inner side of the back frame 1, and the back frame for small unit provided by the embodiment can hook the horizontal pipe of the rack of the small unit 10 through the hook 42 of the lower connecting piece 4 when used, and the upper end of the unit is fixed by the binding belt 2 combined with the connecting hole 34, so that the small unit can be fixed on the back frame 1 as a whole, and the small unit 10 can be transported at any time when working in the wild, which is especially suitable for rugged mountain road environment, and the manual transportation is more convenient and fast; and the overall back frame is simple in price and convenient to manufacture and process, and does not increase much weight when being carried.

[0035] In some embodiments, the first connecting plate 31 and the horizontal plate 32 are integrally formed; the second connecting plate 41 and the hook 42 are integrally formed; the upper connecting member 3 and the lower connecting member 4 are both integrally formed, which can ensure the structural strength of the connecting members.

[0036] In this embodiment, the back plate 1 has multiple first bolt holes 5, and the first connecting plate 31 is detachably connected to the back plate 1 via bolts and the first bolt holes 5; the back plate 1 has multiple second bolt holes 6, and the second connecting plate 41 is detachably connected to the back plate 1 via bolts and the second bolt holes 6. That is, both the upper connecting member 3 and the lower connecting member 4 are detachably connected to the back plate 1 via bolts, and the back plate 1 has corresponding sets of bolt holes, specifically, as shown below. Figure 1 As shown, the back plate 1 has at least two rows of first bolt holes 5 for each first connecting plate 31, and each row of first bolt holes 5 includes at least three bolt holes distributed vertically, thereby enabling adjustment of the vertical height of the first connecting plate 31 and the width between the left and right first connecting plates 31. Similarly, the back plate 1 has at least two rows of second bolt holes 6 for each second connecting plate 42, thereby enabling adjustment of the width between the left and right second connecting plates 42. When the size of the small unit 10 being carried is large, adjusting the connection position of the first connecting plate 31 and the second connecting plate 41 on the back frame 1 (increasing the distance between the left and right first connecting plates 31 and the distance between the left and right second connecting plates 41) will correspondingly adjust the position of the connecting hole 34 and the hook 42 to adapt to the size of the small unit and ensure the stability of the fixation. The same applies to the opposite.
