Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost, in particular to an adjustable engineering cost budget workbench. Background Art

[0002] To put it simply, project cost refers to the construction price of the project. The three elements of project cost are: quantity, price, and fee. In a broad sense, project cost covers construction project cost (civil engineering and installation), highway project cost, water transport project cost, railway project cost, water conservancy project cost, power project cost, communication project cost, aerospace project cost, etc. Project cost refers to all the expenses spent on the construction of the project. The main tasks of project cost are: to calculate the direct costs (labor, materials and equipment, construction machinery and equipment), enterprise management fees, measures fees, fees, profits and taxes included in the project according to drawings, quotas and list specifications. Project cost refers to the price of the project, that is, the price of the construction and installation project and the total price of the construction project formed through bidding and other transactions in the land, equipment, technical services and contracting markets for the completion of a project;

[0003] Most of the existing engineering cost estimation workbenches have a limited adjustable range or cannot be adjusted, which may not meet the needs of different users, thus affecting the comfort and applicability of the work.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0027] See also Figure 1-5 The utility model provides a technical solution: an adjustable engineering cost budget workbench, including: a base 1, a telescopic sleeve 2, a telescopic rod 3, a workbench 4, a threaded rod 5, an internal threaded sleeve block 6, a motor 7, a bevel gear 8, a support plate 9, a connecting plate 10, a rack 11, a gear 12, an electric push rod 13, a connecting block 14, a slider 15, a first connecting rod 16, a tension spring 17, a fixing rod 18, a spring 19, a second connecting rod 20, and a pull rod 21.

[0028] First, as attached Figure 1 As shown in , when the device is used, the motor 7 is first started. Since the bevel gear 8 on the output end of the motor 7 meshes with the bevel gear 8 on the rod body of the threaded rod 5, the motor 7 drives the threaded rod 5 to rotate through the bevel gear 8. Since the threaded rod 5 is connected to the inner wall of the internal threaded sleeve block 6 through threads, the threaded rod 5 drives the telescopic rod 3 to slide inside the telescopic sleeve 2 through the internal threaded sleeve block 6, so that the telescopic rod 3 drives the workbench 4 to rise and fall, and at the same time, the connecting block 14 drives the connecting plate 10 to slide inside the support plate 9, thereby adjusting the height of the workbench 4;

[0029] As attached Figure 1 , Attachment Figure 2 and attached Figure 5 As shown in , after the height adjustment of the workbench 4 is completed, the file or paper is placed on the surface of the workbench 4, and then according to the size of the file or paper, the pull ring on the pull rod 21 is pulled, so that the pull rod 21 drives the slider 15 to slide on the side wall of the workbench 4 through the second connecting rod 20, so that the slider 15 drives the first connecting rod 16 to move, and at the same time, the slider 15 drives the tension spring 17 to stretch, so that the first connecting rod 16 is consistent with the length of the file or paper. Since the rod body of the pull rod 21 is provided with a through hole, the insertion rod is inserted into the through hole to fix the pull rod 21. Since the first connecting rod 16 is arranged in an "L"-shaped structure, the fixing rod 18 is pulled to slide on the rod body of the first connecting rod 16, so that the fixing rod 18 drives the spring 19 to compress, and then the fixing rod 18 fits with the top of the workbench 4, and then the elastic force of the spring 19 drives the fixing rod 18 to reset, so that the fixing rod 18 fixes the file or paper;

[0030] As attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown in the figure, when displaying documents or papers, the electric push rod 13 is started. Since the output end of the electric push rod 13 is fixedly connected to the rack 11, the rack 11 slides inside the connecting plate 10. Since the rack 11 and the gear 12 are meshed with each other, the rack 11 drives the gear 12 to rotate. Then, the rack 11 is fixedly connected to one end of the gear 12 through the connecting block 14, and the top of the connecting block 14 is connected to the bottom of the workbench 4, so that the gear 12 drives the workbench 4 to flip through the connecting block 14, thereby displaying the documents or papers on the surface of the workbench 4, and the work can also be facilitated by fine-tuning.
