The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0027] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a tool box for engineering cost includes a shell 1, a bottom plate 2, a support frame 3 and a placement plate 4. The inner wall of the shell 1 is provided with multiple groups of support frame assemblies, and the support frame assembly includes two symmetrical support frames 3, between which the bottom plate 2 is slidably installed, and the top of the bottom plate 2 is provided with a placement plate 4. The bottom plate 2 and the placement plate 4 are fixedly connected by an installation device 5. The installation device 5 includes a limiting groove 51, a positioning plate 52, a positioning groove 53 and a limiting rod 54. The bottom plate 2 is provided with a positioning groove 53, and the top corners of the bottom plate 2 are all A limiting rod 54 is fixedly installed, a positioning plate 52 is fixedly installed on the bottom end of the placement plate 4, the positioning plate 52 is slidably plugged into the positioning groove 53, a limiting groove 51 is opened at the position corresponding to the bottom end of the placement plate 4 and the limiting rod 54, the limiting groove 51 is slidably plugged into the limiting rod 54, an adjusting device 6 is symmetrically arranged on the inner wall of the outer shell 1, the adjusting device 6 is slidably connected to the support frame 3, the adjusting device 6 is used to adjust the height and spacing between the support frames 3, a moving device 7 is fixedly installed inside the support frame 3, and the moving device 7 is used to quickly move the base plate 2.

[0028] During use, according to the size and specifications of the tools of the project quotation that need to be placed, the placement plate 4 of the corresponding size and specification is installed inside the bottom plate 2 through the installation device 5, and the limiting groove 51 is aligned with the limiting rod 54 inside the bottom plate 2, and the placement plate 4 is pressed after insertion to connect the positioning groove 53 with the positioning plate 52, so as to complete the rapid positioning of the placement plate 4 and prevent the placement plate 4 from shaking during use. Then, according to the different sizes of the placement plates 4, the adjustment device 6 is used to move and adjust the spacing between the support frames 3 to complete the cutting and full utilization of the internal space of the tool box. Finally, through the use of the moving device 7, the bottom plate 2 can be quickly slid, which is convenient for the bottom plate 2 to be pulled out and the components and tools inside the placement plate 4 can be taken, so that the tool box as a whole is more stable and convenient when in use, and the utilization rate of the internal space is more perfect.

[0029] By the attached Figure 3 As shown, in this embodiment, rectangular slots are equidistantly opened inside the bottom plate 2. During use, the opening of the rectangular slots inside the bottom plate 2 can effectively reduce the weight of the bottom plate 2 itself and reduce the squeezing of the support frame 3 by the bottom plate 2 when inside the outer shell 1.

[0030] By the attached Figure 4 As shown, in this embodiment, the adjustment device 6 includes a side panel 61, a slide rail 62, a mating end 63 and a threaded rod 65. The side panel 61 is fixed on the inner wall of the outer shell 1. The slide rails 62 are symmetrically provided on both sides of the side panel 61. The mating end 63 is opened on the support frame 3. The mating end 63 is slidably connected with the slide rail 62. A threaded groove 64 is opened inside the support frame 3. A threaded rod 65 is installed with threads inside the threaded groove 64. The mating end 63 is fixed to the side panel 61 by fastening with the threaded rod 65.

[0031] During use, by pushing the support frame 3, the mating end 63 can move up and down stably on the surface of the side plate 61, and because of the existence of the slide rail 62, the movement of the support frame 3 is more accurate and stable to prevent deviation. When it moves to the target position, the threaded rod 65 can be turned into the threaded groove 64 to complete the locking and adjustment of the position of the support frame 3.

[0032] By the attached Figure 4 As shown, in this embodiment, a plurality of connecting grooves arranged at equal intervals are provided on the side plate 61 opposite to the threaded groove 64. The threaded rod 65 extends out of the threaded groove 64 and can extend into the interior of the connecting groove. When in use, the threaded rod 65 can pass through the threaded groove 64 and enter the interior of the connecting groove at the same time, and the positioning effect is more stable.

[0033] By the attached Figure 5 As shown, in this embodiment, the moving device 7 includes a rotating rod 72 and a conveying wheel 73. A rotating groove 71 is opened inside the support frame 3. The rotating rod 72 is equidistantly arranged inside the rotating groove 71. The conveying wheel 73 is fixedly installed outside the rotating rod 72.

[0034] When the bottom plate 2 is pulled during use, the bottom surface of the bottom plate 2 contacts the outer surface of the conveying wheel 73, and then due to the movement of the bottom plate 2, the conveying wheel 73 itself rotates with the cooperation of the rotating rod 72, making the bottom plate 2 more flexible to be pulled out.

[0035] By the attached Figure 5 As shown, in this embodiment, the edges at both ends of the conveying wheel 73 are set to be chamfered, and the outer surface of the conveying wheel 73 is wrapped with a rubber layer, which can enhance the friction between the conveying wheel 73 and the bottom plate 2 when sliding during use, and prevent the bottom plate 2 from being directly pulled out due to shaking. The chamfered design can effectively prevent the outer surface of the conveying wheel 73 from contacting the bottom surface of the bottom plate 2 and causing scratches on the bottom surface of the bottom plate 2.

[0036] By the attached Figure 5 As shown, in this embodiment, the inner wall of the housing 1 is symmetrically fixed with disassembly blocks, and the disassembly blocks are composed of baffles, wing plates and reinforcement rods, which facilitates flexible adjustment and change of the number of support frames 3 during use.

[0037] The working principle of the utility model is as follows: when using it, the staff installs the placement plate 4 of the corresponding size and specification into the bottom plate 2 through the installation device 5 according to the size and specification of the tools of the project quotation that need to be placed, and presses the placement plate 4 after the limit groove 51 is aligned with the limit rod 54 inside the bottom plate 2, so that the positioning groove 53 and the positioning plate 52 are connected, so as to complete the rapid positioning of the placement plate 4 and prevent the placement plate 4 from shaking during use. Afterwards, the adjustment device 6 is used according to the size of the placement plate 4 to move and adjust the spacing between the support frames 3, so as to complete the cutting and full use of the internal space of the tool box, and the matching end 63 is stably moved up and down on the surface of the side plate 61 by pushing the support frame 3. The support frame 3 can be moved accurately and stably due to the existence of the slide rail 62 to prevent deviation. After moving to the target position, the threaded rod 65 can be rotated into the threaded groove 64 to complete the locking and adjustment of the position of the support frame 3. Finally, through the use of the moving device 7, the bottom plate 2 can be quickly slid, which is convenient for the bottom plate 2 to be pulled out and the parts and tools inside the placement plate 4 can be taken out. When the bottom plate 2 itself is pulled, the bottom surface of the bottom plate 2 contacts the outer surface of the conveying wheel 73. Then, due to the movement of the bottom plate 2, the conveying wheel 73 itself rotates with the cooperation of the rotating rod 72, making the extraction of the bottom plate 2 more flexible, making the tool box as a whole more stable and convenient when in use, and the utilization rate of the internal space more perfect.
