The Project Cost Operation Console is a tool designed specifically for construction project cost budgeting, aiming to improve the efficiency and accuracy of project cost budgeting.

[0003] Since the operating table used for engineering cost management generally has a certain size, it is not convenient to carry and use outside, and cannot meet the needs of different work scenarios, which reduces the flexibility and practicality of the operating table. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a portable engineering cost operating table, which has the advantages of being easy to retract, adjust and carry, and improving the flexibility and practicality of the operating table. It solves the problem that operating tables used for engineering cost generally have a certain size, are inconvenient to carry and use outside, cannot meet the needs of different work scenarios, and reduce the flexibility and practicality of the operating table.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a portable engineering cost operating table, comprising a main body, a telescopic pull rod is provided inside the main body, two rollers are provided at one end of the main body away from the telescopic pull rod, four rotating shafts are rotatably connected inside the main body, the outer circumference of each rotating shaft is fixedly connected to a base, each of the bases is rotatably connected inside with a screw rod, the outer circumference of the screw rod is threadedly connected to a support foot, and two telescopic plates are slidably connected inside the main body.

[0006] Through the above solution, since the operating table used for engineering cost generally has a certain size, it is not convenient to carry and use outside, and cannot meet the needs of different work scenarios, which reduces the flexibility and practicality of the operating table. By setting a telescopic pull rod and rollers, it is convenient to move and transport the operating table. By setting a telescopic plate that can be retracted and a base that can be rotatable, it is convenient to retract and adjust the operating table, avoiding the operating table taking up too much external space, further providing convenience for carrying and using outside, and improving the flexibility and practicality of the operating table.

[0007] Furthermore, a first positioning plate is fixedly sleeved on the outer circumferential surface of each rotating shaft, a first positioning rod is slidably inserted inside the first positioning plate, four first positioning holes are opened inside the body, and four second positioning holes are opened inside the body.

[0008] Through the above solution, the first positioning plate is positioned and restricted by the first positioning rod and the first positioning hole and the second positioning hole, thereby positioning and restricting the rotating shaft and the base, making it easy to adjust the base and the legs.

[0009] Furthermore, a first spring is fixedly connected to the outer surface of the first positioning rod, and the other end of the first spring is fixedly connected to the outer surface of the first positioning plate.

[0010] Through the above solution, the first spring can use its own elastic force to force the first positioning rod to always be inserted into the first positioning hole or the second positioning hole, so as to position the base and the support leg.

[0011] Furthermore, four second positioning rods are slidably inserted into the interior of the main body, two third positioning holes are provided in the interior of each telescopic plate, and two fourth positioning holes are provided in the interior of each telescopic plate.

[0012] According to the above solution, the telescopic plate is positioned by the second positioning rod and the third positioning hole and the fourth positioning hole, and then the telescopic plate can be retracted and used.

[0013] Furthermore, four columns are fixedly connected to the bottom surface of the main body, and the outer circumferential surfaces of two adjacent columns are slidably connected to a second positioning plate. The outer circumferential surfaces of two adjacent second positioning rods are fixedly plugged into the interior of the second positioning plate, and the outer surface of each second positioning rod is fixedly connected to a second spring, and the top end of the second spring is fixedly connected to the bottom surface of the second positioning plate.

[0014] Through the above solution, the second spring can rely on its own elastic force to keep the second positioning rod inserted into the third positioning hole or the fourth positioning hole to position the telescopic plate.

[0015] Furthermore, a control rod is rotatably inserted inside each base, a first gear is fixedly sleeved on the outer circumference of the control rod, and a second gear is fixedly sleeved on the outer circumference of each screw rod, and the second gear is meshed with the first gear.

[0016] Through the above solution, the rotatable control lever drives the second gear to rotate through the first gear, prompting the screw rod to drive the supporting legs to retract and extend, thereby adjusting the overall height of the operating table.

[0017] Furthermore, the outer circumference of each screw rod is fixedly sleeved with a first limiting ring, and the outer circumference of the first limiting ring is connected to the inner rotation of the base. The outer circumference of each control rod is fixedly sleeved with a second limiting ring, and the outer circumference of the second limiting ring is connected to the inner rotation of the base.

[0018] Through the above solution, the first limiting ring can limit the screw rod to prevent the screw rod from sliding and deviating, and the second limiting ring can limit the control rod to prevent the control rod from sliding and deviating.

[0019] Furthermore, the outer circumferential surface of each of the support legs is fixedly connected to two first limit blocks, and the outer surface of each of the first limit blocks is slidably connected to the base through a hollow groove opened inside the base. The outer surface of each of the telescopic plates is fixedly connected to two second limit blocks, and the outer surface of each of the second limit blocks is slidably connected to the body through a hollow groove opened inside the body.

[0020] Through the above scheme, the first limit block can limit the support leg, prevent the support leg from rotating with the screw rod, prompt the support leg to always move laterally, and prevent the support leg from sliding and falling off. The second limit block can limit the telescopic plate, preventing the telescopic plate from falling off easily.

[0040] A portable engineering cost operating table in this embodiment is convenient for moving and transporting the operating table by providing a telescopic pull rod 2 and rollers 3. By providing a telescopic plate 13 that can be extended and retracted and a base 5 that can be rotatable, the operating table can be easily retracted and adjusted, thereby avoiding the operating table from occupying too much external space, further providing convenience for carrying and using outside, improving the flexibility and practicality of the operating table, and solving the problem that existing engineering cost operating tables generally have a certain size, are not convenient for carrying and using outside, cannot meet the needs of different work scenarios, and reduce the flexibility and practicality of the operating table.

[0041] It should be noted that the telescopic pull rod 2 is a suitcase-type pull rod, and a button is provided on the top of the telescopic pull rod 2, and the telescopic length of the telescopic pull rod 2 can be controlled by the button.

[0042] The working principle of the above embodiment is:

[0043] When the operating table needs to be opened for use, the first positioning rod 9 is pulled out from the first positioning hole 11, and then the base 5 is rotated ninety degrees. The base 5 drives the first positioning plate 8 and the first positioning rod 9 to rotate ninety degrees through the rotating shaft 4. At this time, the first positioning rod 9 rotates to the position of the second positioning hole 12, and the first positioning rod 9 is released, prompting the first positioning rod 9 to move back and insert into the second positioning hole 12 under the action of the first spring 10 to position the base 5. After opening the four bases 5 in turn, the operating table can be supported by the supporting legs 7 and placed on the ground for use. When the space on the operating table is not enough, the second positioning plate 15 can be pulled down to drive the second positioning rod 14 to move out from the third positioning hole 16, thereby releasing the positioning restriction of the telescopic plate 13, and then the telescopic plate 13 is pulled out from the inside of the body 1. At this time, the second positioning rod 14 and the fourth positioning hole 17 corresponds to the position of the second positioning plate 15, release the second positioning plate 15, and then the second positioning plate 15 moves back under the action of the second spring 19, prompting the second positioning rod 14 to be inserted into the fourth positioning hole 17 to position the telescopic plate 13. After the telescopic plates 13 on both sides are opened, the usable area of the operating table can be increased. The rotatable control rod 21 drives the screw rod 6 to rotate through the first gear 22 and the second gear 23, and the screw rod 6 drives the support leg 7 to retract and move, thereby adjusting the overall height of the operating table. When the operating table needs to be carried out for use, the base 5 and the telescopic plate 13 can be put into the main body 1 in turn, and the base 5 and the telescopic plate 13 can be positioned respectively by the first positioning rod 9, the first positioning hole 11, the second positioning rod 14, and the third positioning hole 16. Then, the telescopic pull rod 2 is pulled out, and the operating table can be moved by relying on the telescopic pull rod 2 and the roller 3.
