It includes a toolbox mechanism for storing tools for road and bridge survey sites, and a design drawing placement mechanism for placing design drawings is provided on one side of the toolbox mechanism, and a plurality of design drawing fixing mechanisms for fixing the design drawings are provided on one side of the design drawing placement mechanism. The utility model provides a table board for placing design drawings on one side of the second box body, and two arc-shaped sleeves are respectively placed on the two corners of the table board, so that the design drawings are initially fixed by clamping force generated from the corners of the table board, and the design drawings are pressed again by the limit pressing blocks from both sides of the table board to fix them again, thereby improving the protection of the design drawings, making it more convenient for designers to use in practice.

[0004] However, there are some problems. The placement height of the box is certain, which cannot meet the needs of users in different scenarios. In addition, the table top cannot be placed flat on an uneven surface, and there will be an angle, which is not conducive to design and use. Therefore, a portable tool box for road and bridge design is proposed. Summary of the invention

Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-4 The utility model embodiment proposes a portable tool box for road and bridge design, including a portable box body 1 that can be opened, closed and locked, a lifting strap 2 is installed on the left side of the portable box body 1, a writing base plate 4 is installed on the top of the portable box body 1, and an assembly plate 3 is installed on the bottom of the portable box body 1. Two accommodating grooves 5 are provided at the bottom of the assembly plate 3, and two symmetrical constraint hoops 6 hinged to the assembly plate 3 are arranged below each of the accommodating grooves 5. Connecting bolts 7 are installed on the constraint hoops 6, and a support component is hinged at the end of each accommodating groove 5, a limiting component is installed on the support component, and a control component is arranged on the side of the limiting component.

[0030] The support assembly includes an articulated seat 82 installed in the accommodating groove 5 through a rotating shaft, a support sleeve 81 is installed at the bottom of the articulated seat 82, a support rod 83 is slidably connected in the support sleeve 81, one end of a spring 84 is fixedly connected to the top of the support rod 83, and the other end of the spring 84 is fixedly connected to the inner top wall of the support sleeve 81, a rotating hole 85 is opened on the articulated seat 82, and an insertion hole 86 located on the articulated seat 82 is opened below the rotating hole 85. The portable case 1 can be supported by the support assembly to ensure the balance of the portable case 1 when in use, avoid the writing base 4 on the top of the portable case 1 from being tilted, which is inconvenient to use, and the height can be adjusted to adapt to the needs of the user.

[0031] The hinge seat 82 can move in the accommodating groove 5 through the rotating shaft, and sliders are installed on both sides of the top of the support rod 83. The inner wall of the support sleeve 81 is provided with a sliding groove matching the slider. The front and rear sides of the assembly plate 3 are installed with locking bolts adapted to the insertion hole 86 and the positions correspond to each other. The hinge seat 82 is used in conjunction with the rotating shaft to allow the support sleeve 81 to be retracted into or extended out of the accommodating groove 5, so that it can be converted between being portable and being used as a platform. The cooperation of the slider and the sliding groove can allow the support rod 83 to move stably and will not separate from the support sleeve 81. The cooperation of the locking bolt and the insertion hole 86 can limit the support sleeve 81 to prevent the support assembly from being unstable when in use.

[0032] The limiting component includes a rotating table 91 rotatably connected to the outside of the support sleeve 81 and a movable groove 93 opened on the support sleeve 81, a movable sheet 94 is slidably connected to the inside of the movable groove 93, a friction top rod 95 is fixedly connected in the middle of the movable sheet 94, a spring 96 is arranged between the movable sheet 94 and the groove wall of the movable groove 93, and a groove 97 is arranged on the inner side of the rotating table 91 at a position opposite to the movable groove 93. The limiting component can be used to limit the support rod 83. After the support rod 83 is extended a certain distance, the rotating table 91 can be rotated to limit the support rod 83 to ensure that the support rod 83 will not retract by itself under force during use.

[0033] A rotating ring is fixedly connected to the inner side of the rotating table 91 , and a rotating groove matching the rotating ring is opened on the outer side of the supporting sleeve 81 . The rotating ring is used to limit the rotating table 91 from moving up and down and ensure the rotation of the rotating table 91 .

[0034] The control component includes a fixing frame 101 installed on the outside of the supporting sleeve 81, a latch 102 is slidably connected to the fixing frame 101, one end of the latch 102 is fixedly connected to a plug 103, a spring 104 is installed between the other end of the latch 102 and the fixing frame 101, and a plurality of insertion ports 105 are provided on the outside of the rotating table 91. The control component can be used to limit the rotation of the rotating table 91, so that the rotating table 91 will not rotate at will after its position is determined.

[0035] The plurality of insertion openings 105 are distributed in a circular shape, and the insertion openings 105 match the insertion piece 103 . By virtue of the cooperation between the insertion openings 105 and the insertion piece 103 , the insertion piece 103 can be rotated or fixed.

[0036] The specific implementation method is as follows: when in use, the support sleeve 81 and the support rod 83 are initially restricted in the receiving groove 5 by the restraining hoop 6. One receiving groove 5 can accommodate two support sleeves 81 and support rods 83 in the shortest state, so that the portable box 1 can be carried by the pulling strap 2. Various tools for design can be placed in the portable box 1. When it is needed, the restraining hoop 6 is opened by the connecting bolt 7 to release the support sleeve 81. Then, the locking bolt and the insertion hole 86 are used to make the support sleeve 81 in a vertical state for easy support. The writing base plate 4 is used to place the tools for on-site design. When the placement surface is uneven, the latch 102 can be pulled to separate the insert 103 from the insertion port 105. At this time, the rotating table 91 can be rotated, so that the friction top rod 95 When in the groove 97, the pressure on the friction top rod 95 is released, allowing the support rod 83 to move vertically, and then under the action of the spring 84, the support rod 83 extends out of the support sleeve 81, and the bottom of the support rod 83 contacts the ground. According to the situation of the placement surface, the extension length of the support rod 83 is different, and it contacts the placement surface. In this way, it can adapt to the unevenness of the placement surface by itself, ensuring the parallelism of the writing base plate 4 is conducive to the use of the writing base plate 4. After determining the extension length of the support rod 83, the rotating table 91 is rotated again, so that the groove 97 on the rotating table 91 squeezes the friction top rod 95, contacts the surface of the support sleeve 81, and applies pressure to limit the support rod 83 and limit the height. In this way, the writing base plate 4 can be used stably, and the height of use can also be adjusted to meet the needs of users in turn.
