[0032] like Figure 1 , Figure 2 and Figure 3As shown, an embodiment of the utility model provides a carrying case with an adjustment function, comprising a first box body 1, a second box body 2 is installed at the bottom outer edge of the first box body 1, hollow cavities 21 are symmetrically opened on the adjacent two side edges of the first box body 1 and the second box body 2, limiting strips 3 are symmetrically protruding on the inner side edge of the second box body 2, and limiting grooves 4 are symmetrically opened on the outer side edge of the first box body 1, and the limiting strips 3 and the limiting grooves 4 are matched and plugged in. Through the cooperation between the set limiting grooves 4 and the limiting strips 3, it can play an auxiliary limiting role when the second box body 2 moves during work, and try to avoid the first box body 1 and the second box body 2 from being misaligned during adjustment.

[0033] A positioning hole 5 is drilled and installed on one side of the limit groove 4 of the first box body 1. There are a plurality of positioning holes 5, which are equidistantly arranged from top to bottom on the side of the first box body 1. A positioning bolt 6 is installed on the middle section of one side of the second box body 2 facing the limit strip 3, and the second box body 2 and the positioning bolt 6 are threadedly matched.

[0034] By cooperating between the first box body 1 and the second box body 2 as well as the positioning holes 5 and the positioning bolts 6, the overall size of the box body composed of the first box body 1 and the second box body 2 can be pre-adjusted according to the number of fire hoses during operation, thereby improving the overall practicality of the carrying case. At the same time, the carrying case can be reduced to a corresponding size after use to reduce the overall footprint.

[0035] The top of the first box body 1 is hollow, and a top plate 7 is hingedly installed on the top of the first box body 1 through a hinge. The middle section of the top plate 7 is hollow to form a handle 8. A fixing plate is fixed to the middle section of one side of the first box body 1 away from the second box body 2, and a receiving rod 9 is fixed on the fixing plate, forming a U-shape between the fixing plate and the receiving rod 9.

[0036] By providing the receiving rod 9, the rope body and the like can be conveniently fixed on the corresponding receiving rod 9 for subsequent carrying during work, and by providing the handle 8, the firefighters can conveniently hold the handle 8 to carry the carrying box.

[0037] Reference Figure 1 and Figure 4 As shown, a positioning cavity is provided at one end of the top plate 7 away from the hinge, and a positioning assembly 10 is installed in the positioning cavity. Positioning holes 101 are symmetrically provided on the inner side of the first box body 1, and the positioning assembly 10 and the positioning hole 101 are plugged in. The positioning assembly 10 includes an insert block 14 symmetrically arranged in the positioning cavity, a screw rod 13 is installed on the insert block 14, the screw rod 13 and the insert block 14 are threadedly matched, and the insert block 14 and the positioning hole 101 are plugged in. A second bevel gear 12 is fixed to one adjacent end of the two screw rods 13, and a first bevel gear 11 is rotatably provided at the middle section of the top plate 7 corresponding to the positioning cavity, and the first bevel gear 11 and the second bevel gear 12 are meshed for transmission.

[0038] Through the positioning assembly 10, the knob 111 drives the first bevel gear 11 to rotate as a whole, and the first bevel gear 11 and the second bevel gear 12 are meshed and transmitted, so that the second bevel gear 12 rotates as a whole, and the second bevel gear 12 drives the screw rod 13 to rotate, and the screw rod 13 and the plug block 14 are threadedly matched, so that the plug block 14 is extended as a whole, so that the plug block 14 is plugged and installed in the corresponding positioning socket 101, which can facilitate the adjustment of the top plate 7 according to different work requirements, and ensure that the top plate 7 is fixed at the corresponding position during work, thereby ensuring the overall stability of the top plate 7 after being fixed.

[0039] The vertical cross-section of the above-mentioned plug block 14 is rectangular, one side of the first bevel gear 11 extends out of the top plate 7, and a knob 111 is fixed to the end of the first bevel gear 11 extending out of the top plate 7. By designing the cross-section of the plug block 14 to be rectangular, it can be ensured that the plug block 14 can only move horizontally during the adjustment of the plug block 14, and the rotation of the plug block 14 can be avoided as much as possible.

[0040] The working principle provided by the utility model is:

[0041] When it is necessary to carry the water pipe, etc., reverse the positioning bolt 6, the second box body 2 and the positioning bolt 6 are threaded together, so that one end of the positioning bolt 6 is withdrawn from the positioning hole 5. At this time, move the second box body 2 to the specified position, turn the positioning bolt 6 forward, the second box body 2 and the positioning bolt 6 are threaded together, and the positioning bolt 6 is inserted into the corresponding second box body 2, thereby determining the overall size of the carrying case.

[0042] During operation, the water pipes are stacked in sequence between the first box body 1 and the second box body 2. After the water pipes are stacked, the rope body is tied to the receiving rod 9, the top plate 7 is closed as a whole, and the knob 111 is turned. The knob 111 drives the first bevel gear 11 to rotate as a whole, and the first bevel gear 11 and the second bevel gear 12 are meshed and transmitted, so that the second bevel gear 12 rotates as a whole, and the second bevel gear 12 drives the screw rod 13 to rotate. The screw rod 13 and the plug block 14 are threadedly matched, so that the plug block 14 is extended as a whole, so that the plug block 14 is inserted and installed in the corresponding positioning socket 101, thereby completing the overall positioning of the top plate 7.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
