Abstract
Description
Technical Field
[0001] This utility model relates to the field of workbench technology, and in particular to an engineering cost estimation workbench. Background Technology
[0002] Construction cost refers to the value of human, material, and financial resources required to complete a construction project. It serves as the foundational data for all stages of the project, including design, construction, and supervision, and is a core component of project economic management.
[0003] However, in existing technologies, engineering costs often need to be measured and estimated in conjunction with the engineering site. However, most existing workbenches are of an integrated structure, which is inconvenient to move and very troublesome to carry outdoors. Therefore, we propose an engineering cost estimation workbench. Utility Model Content
[0004] This utility model provides an engineering cost estimation workbench, which solves the above-mentioned technical problems.
[0005] The solution of this utility model to solve the above-mentioned technical problems is as follows: an engineering cost estimation workbench includes a tabletop, two H-shaped support frames are vertically arranged below the tabletop, the upper ends of the two support frames are respectively movably embedded in the tabletop, the upper part of the support frame is connected to the tabletop through a snap-fit mechanism, a scissor frame is arranged between the two support frames, and sliders are rotatably installed at both ends of the scissor frame, the sliders are connected to the support frames through a sliding mechanism.
[0006] Preferably, the locking mechanism includes a groove laterally formed on the inner wall of the support frame, a locking block is fixedly installed on the inner wall of the groove by a spring, the locking block is movably embedded in the table surface, and the locking block is connected to a locking cancellation mechanism.
[0007] Preferably, the latching cancellation mechanism includes a rotating rod that is vertically rotatably mounted on the upper part of the support frame.

[0009] Preferably, a knob is fixedly installed on the upper end of the rotating rod.
[0010] The beneficial effects of this utility model are:
[0011] By separating the platform and support frame, the device can be moved more easily during transport. The support frame and platform are secured by snap-fit rods within the support frame, simplifying installation. Furthermore, the two snap-fit components on the same support frame are controlled by a single rotating rod, further simplifying operation. Additionally, a scissor frame connects the two support frames, allowing for foldable storage and limiting the movement of the two frames. The platform and support frame can also be stored separately during transport.

[0020] The following is in conjunction with the appendix Figure 1-4The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0021] like Figure 1-4 As shown, this utility model discloses an engineering cost estimation workbench, including a work surface 1. Two H-shaped support frames 2 are vertically arranged below the work surface 1. The upper ends of the two support frames 2 are movably embedded into the work surface. The upper part of the support frames 2 is connected to the work surface 1 via a snap-fit mechanism. A scissor frame 3 is arranged between the two support frames 2. Slider blocks 4 are rotatably installed at both ends of the scissor frame 3. The sliders 4 are connected to the support frames 2 via a sliding mechanism. The two support frames 2 are connected by a foldable scissor frame 3. This allows for folding and storage of the two support frames 2, reducing space occupation during transport. Extending the scissor frame 3 to its maximum distance allows for connection between the work surface 1 and the support frames 2, making the connection more convenient. This device uses snap-fit blocks 7 to connect the support frames 2 and the work surface 1, allowing for quick docking and installation. Simultaneously, the work surface 1 and the support frames 2 can be stored and transported separately, making them more convenient to carry.
[0022] Specifically, the snap-fit mechanism includes a groove 5 horizontally opened on the inner wall of the support frame 2. A snap-fit block 7 is fixedly installed on the inner wall of the groove 5 by a spring 6. The snap-fit block 7 is movably embedded in the table surface 1. The snap-fit block 7 is connected to a snap-fit cancellation mechanism. The spring 6 pushes the snap-fit block 7 to move outward, and the snap-fit block 7 snaps and fixes itself to the table surface 1, realizing the connection between the table surface 1 and the support frame 2, making the installation and connection between the table surface 1 and the support frame 2 more convenient.
[0023] More specifically, the latching cancellation mechanism includes a rotating rod 8 vertically rotatably mounted on the upper part of the support frame 2. The rotating rod 8 is fixedly connected to the latching block 7 through a steel wire 9 that movably passes through the support frame 2. A spring 6 is movably sleeved on the outer wall of the steel wire 9. Rotating the rotating rod 8 can drive the two corresponding latching blocks 7 on the same side to move, quickly control the cancellation of the latching, and simplify the operation. A knob 12 is fixedly mounted on the upper end of the rotating rod 8, making the operation of the rotating rod 8 more convenient.
[0024] Furthermore, the sliding mechanism includes a slide rail 10 that is vertically fixedly installed on the outer wall of the support frame 2, a slider 4 that is slidably connected to the slide rail 10, and limit blocks 11 that are fixedly installed at the upper and lower ends of the slide rail 10, the limit blocks 11 being used to limit the slider 4 and prevent the slider 4 from separating from the slide rail 10.
[0025] Working principle:
[0026] In use, remove the support frame 2, then stretch the two support frames 2 so that they are far apart from each other, stretch the scissor frame 3 to its maximum length, and then rotate the rotating rod 8 on the support frame 2. The rotation of the rotating rod 8 causes the steel wire 9 to wind around the rotating rod 8. The steel wire 9 pulls the locking block 7 to move, causing the locking block 7 to retract into the groove 5 against the force of the spring 6. Then the table can be placed on the upper end of the support frame 2. Release the rotating rod 8, and the spring 6 pushes the locking block 7 to move out of the groove 5, so that the locking block 7 locks and fixes the table 1.
[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
