[0002] When cost engineers estimate project costs, they often need to find one or several similar projects among the projects they have done in the past, and then subjectively evaluate based on the cost differences and cost time differences of the dissimilar parts. In order to facilitate cost comparison by cost engineers, it is necessary to input the cost sheets of multiple projects into the cloud to complete convenient comparison. In order to facilitate the input of cost sheets, corresponding devices are often required.

[0003] A prior patent (publication number: CN216748404U) discloses a device for inputting and comparing construction costs, belonging to the technical field of cost comparison cloud input devices, including a placement and mounting base.

[0006] To achieve the above object of being able to quickly clamp and release the cost sheet, making it more convenient to fix the cost sheet and facilitating the staff to replace different cost sheets for entry, thereby improving the work efficiency when entering multiple cost sheets, the present application provides the following technical solution: A building cost entry and comparison device, including a base. A threaded rod is rotatably arranged on the top of the base through a support plate.

One end of the first connecting block is arranged at one end of the feeding plate. A positioning rod is arranged on one side of the feeding plate through a fixing block. A positioning frame is slidably arranged on the outer surface of the middle part of the positioning rod. One side of the positioning frame is arranged on one side of the pressing plate. A connecting rod is arranged on the other side of the positioning frame. A connecting frame is slidably arranged on the outer surface of the middle part of the connecting rod. A telescopic inner rod is arranged on the top of the connecting frame. One end of the telescopic inner rod is slidably arranged inside the inner wall of the telescopic outer tube.

One end of the support rod is arranged on the top of the base through a support plate. An entry mechanism is arranged on the top of the base through a support frame.

[0007] Through the above solution, by pressing down the grip rod, the sliding rod cooperates with the first limiting rod to drive the telescopic outer tube to move downward, so that the spring pushes the connecting frame downward through the telescopic inner rod, and then the positioning frame drives the pressing plate to move downward to press and fix the cost sheet, which can quickly clamp and release the cost sheet, is more convenient to fix the cost sheet, facilitates the staff to replace different cost sheets for entry, and improves the work efficiency when entering multiple cost sheets.

[0008] Further, the thread directions on the outer surfaces of both sides of the middle part of the threaded rod are oppositely arranged, and the outer surfaces of both sides of the middle part of the threaded rod are respectively threadedly connected with the inner walls of the middle parts of two first connecting blocks.

One side of the outer surface of one end of the grip is provided with a limiting plate, and the middle outer surface of the limiting plate is slidably arranged inside the middle inner wall of the limiting frame, and the limiting frame is arranged on the top of the pressing rod.

[0017] Through the above solution, by pulling the grip to slide inside the inner wall of one end of the pressing rod, the position of the limiting plate can be adjusted, thereby controlling the cooperation state between the limiting plate and the limiting groove, achieving the fixation of the position of the pressing rod and the adjustment of the position of the pressing rod. The setting of the limiting frame can improve the stability of the movement of the limiting plate.

[0018] Furthermore, a limiting disk is provided on the outer surface of the middle part of the support rod. A plurality of limiting grooves are formed on one side of the outer circumferential surface of the limiting disk, and the middle inner wall of the limiting groove is slidably connected to the outer surface of one end of the limiting plate.

[0019] Through the above solution, when the outer surface of one end of the limiting plate is inserted into the limiting groove, the position of the limiting plate can be fixed through the cooperation of the limiting disk and the support rod, thereby fixing the angle of the pressing rod.

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 , a building cost input and comparison device in this embodiment includes a base 1.

One end of the first connecting block 3 is arranged at one end of the feeding plate 4. A positioning rod 5 is arranged on one side of the feeding plate 4 through a fixing block. A positioning frame 6 is slidably arranged on the outer surface of the middle part of the positioning rod 5. One side of the positioning frame 6 is arranged on one side of the pressing plate 7. The other side of the positioning frame 6 is provided with a connecting rod 8. A connecting frame 9 is slidably arranged on the outer surface of the middle part of the connecting rod 8. A telescopic inner rod 10 is arranged on the top of the connecting frame 9.

A first limiting rod 12 is arranged on the top of the telescopic outer tube 11. A sliding rod 13 is arranged on the top of the first limiting rod 12. The outer surface of the middle part of the sliding rod 13 is slidably arranged inside the inner wall of the pressing rod 14.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 , the thread directions on the outer surfaces of both sides of the middle part of the threaded rod 2 are oppositely arranged. The outer surfaces of both sides of the middle part of the threaded rod 2 are respectively threadedly connected to the inner walls of the middle parts of the two first connecting blocks 3. When the threaded rod 2 rotates, the two first connecting blocks 3 can be driven to move away from or close to each other through the different thread directions on the outer surfaces of both sides of the middle part of the threaded rod 2, so as to adjust the positions of the two feeding plates 4 and make the distance between the feeding plates 4 adapt to the size of the cost table.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 4 , one end of the connecting rod 8 has a quadrilateral cross-section. The shape of the outer surface of the middle part of the connecting rod 8 fits the shape of the inner wall of the middle part of the connecting frame 9. The quadrilateral setting of the connecting rod 8 can cooperate with the connecting frame 9 to fix the angle of the telescopic inner rod 10, avoiding the angle of the telescopic inner rod 10 from tilting and being unable to push the connecting rod 8 downward normally. At the same time, the telescopic inner rod 10 can be prevented from being affected by the movement of the feeding plate 4 when the feeding plate 4 moves through the sliding of the inner wall of the middle part of the connecting frame 9 on the outer surface of the middle part of the connecting rod 8, so that the telescopic inner rod 10 can normally push the pressing plate 7 downward through the connecting rod 8 after the feeding plate 4 moves.

By arranging the spring 23, a thrust can be applied to the telescopic inner rod 10, so that the telescopic outer tube 11 can push the telescopic inner rod 10 to move downward through the spring 23.

[0036] Please refer to Figure 3 , Figure 4 and Figure 5 , one end of the first limiting rod 12 is arranged with a quadrilateral cross-section. The two sides of the outer surface of one end of the first limiting rod 12 are slidably connected with the two sides of the inner wall of the bottom of the pressing rod 14. The two sides of the inner wall of the bottom of the pressing rod 14 are attached to and arranged in parallel with the two sides of the outer surface of one end of the first limiting rod 12. By the cooperation of the two sides of the outer surface of one end of the first limiting rod 12 and the two sides of the inner wall of the bottom of the pressing rod 14, the lateral movement of the first limiting rod 12 can be restricted, avoiding that the lateral movement of the material placing plate 4 will affect the cooperation between the pressing rod 14 and the sliding rod 13.

[0037] Please refer to Figure 3 and Figure 4 , a handle 19 is slidably arranged on the inner wall of one end of the pressing rod 14. One side of the outer surface of one end of the handle 19 is provided with a limiting plate 18. The middle outer surface of the limiting plate 18 is slidably arranged inside the middle inner wall of the limiting frame 20. The limiting frame 20 is arranged on the top of the pressing rod 14. By pulling the handle 19 to slide inside the inner wall of one end of the pressing rod 14, the position of the limiting plate 18 can be adjusted, and then the cooperation state between the limiting plate 18 and the limiting groove 17 can be controlled, realizing the fixation and adjustment of the position of the pressing rod 14. The arrangement of the limiting frame 20 can improve the stability of the movement of the limiting plate 18.

[0038] Please refer to Figure 3 and Figure 4 , a limiting disc 16 is arranged on the middle outer surface of the support rod 15. A plurality of limiting grooves 17 are opened on one side of the outer circumferential surface of the limiting disc 16. The middle inner wall of the limiting groove 17 is slidably connected with the outer surface of one end of the limiting plate 18. When one end of the outer surface of the limiting plate 18 is inserted into the limiting groove 17, the position of the limiting plate 18 can be fixed through the cooperation of the limiting disc 16 and the support rod 15, and then the angle of the pressing rod 14 can be fixed.

[0039] Please refer to Figure 1 , Figure 2 and Figure 4 , one end of the material placing plate 4 is provided with a second connecting block 22. The middle inner wall of the second connecting block 22 is slidably arranged on the outer surface of one side of the middle of the second limiting rod 21. One end of the second limiting rod 21 is arranged on the top of the base 1 through a support plate. By the sliding of the middle inner wall of the second connecting block 22 on the outer surface of the middle of the second limiting rod 21, the angle of the material placing plate 4 during movement can be restricted, improving the stability of the movement of the material placing plate 4.

[0040] A building cost input comparison device in this embodiment can drive the telescopic outer tube 11 to move downward by pressing the grip rod 19 downward. The sliding rod 13 cooperates with the first limiting rod 12 to drive the telescopic outer tube 11 to move downward, so that the spring 23 pushes the connecting frame 9 downward through the telescopic inner rod 10. Then, the positioning frame 6 drives the pressing plate 7 to move downward to press and fix the cost table. It can quickly clamp and release the cost table, which is more convenient for fixing the cost table, facilitating the staff to replace different cost tables for input and improving the working efficiency when inputting multiple cost tables.

[0041] The working principle of the above embodiment is as follows: According to the size of the cost table, rotate the threaded rod 2 to drive the two first connecting blocks 3 to move closer to or away from each other, adjust the distance between the two feeding plates 4, so that the distance between the two feeding plates 4 adapts to the size of the cost table to be input. Place the cost table on the top of the feeding plate 4, pull the grip 19, drive the outer surface of one end of the limiting plate 18 out of the corresponding limiting groove 17, press the grip 19 downward, so that the grip 19 drives the pressure rod 14 to swing downward. When the pressure rod 14 swings downward, the sliding rod 13 will slide inside the inner wall of the middle part of the pressure rod 14, and at the same time, the first limiting rod 12 will slide inside the inner wall of the bottom part of the pressure rod 14. When the pressure rod 14 swings downward, it drives the telescopic outer tube 11 to move downward through the cooperation of the sliding rod 13 and the first limiting rod 12. The telescopic outer tube 11 cooperates with the spring 23 to push the telescopic inner rod 10 downward. The telescopic inner rod 10 drives the inner wall of the middle part of the positioning frame 6 to slide downward on the outer surface of the middle part of the positioning rod 5 through the cooperation of the connecting frame 9 and the connecting rod 8, so that the positioning frame 6 drives the pressing plate 7 to move downward, and the pressing plate 7 presses on the cost table to cooperate with the feeding plate 4 to clamp and fix the cost table. After fixing, continuously press the grip 19 to compress the spring 23 by the cooperation of the telescopic outer tube 11 and the telescopic inner rod 10. The outer surface of one end of the limiting plate 18 moves to the corresponding limiting groove 17, and push the grip 19 into the inner wall of one end of the pressure rod 14, so that the outer surface of one end of the limiting plate 18 is inserted into the corresponding limiting groove 17 to fix the position of the pressure rod 14. The input mechanism 24 starts to input the cost table below. When it is necessary to replace the cost table, pull the grip 19 to make the outer surface of one end of the limiting plate 18 pull out of the limiting groove 17, and lift the grip 19 upward to drive the pressure rod 14 to swing upward, so that the pressing plate 7 moves upward to release the pressing on the cost table.
