Description

Technical Field

[0001] This utility model belongs to the field of classification device technology, specifically relating to a classification device for tender documents used in construction engineering cost estimation. Background Technology

[0002] Construction project bidding refers to the legal act by which a construction unit issues a public notice for a proposed project, attracts contractors to compete for the project through legal procedures and methods, and selects the best contractor to complete the construction task. When bidding for construction projects, construction companies need to submit bidding documents to the bidding unit. The bidding documents are usually printed and bound. After printing the bid documents, they need to be classified and stored to facilitate subsequent binding.

[0003] The current bidding document classification devices for construction project cost estimates mostly have fixed cell sizes, making it inconvenient to adjust the cell size according to classification needs, which makes it very inconvenient for users. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed bidding document classification device for construction engineering cost in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A bidding document classification device for construction project cost estimates includes a storage box. A first partition is fixedly connected to the inner cavity of the storage box. Multiple second partitions perpendicular to the first partition are slidably connected to the first partition. Two symmetrically arranged limiting rods are fixedly installed in the inner cavity at the top of the storage box along the length of the storage box. Grooves are formed on the opposite side of the two limiting rods. Multiple limiting plates are equidistantly arranged in the grooves, and limiting grooves are formed between adjacent limiting plates. Two upper sliding rings are fixedly installed on the top of the second partition. The two upper sliding rings are respectively sleeved on the two limiting rods and slidably connected to the limiting rods. A limiting slider is slidably passed through the side wall of the upper sliding ring near the groove. A connecting rod is fixedly connected to the end of the limiting slider away from the limiting plate. The connecting rod has a U-shaped structure. The middle section of the connecting rod passes through the upper sliding ring below the limiting rod and is slidably connected to the upper sliding ring. A button is fixedly connected to the end of the connecting rod away from the limiting slider. A spring is sleeved on the connecting rod between the button and the side wall of the upper sliding ring.

[0007] As a further optimization of this utility model, a sliding groove is provided in the middle section of the second partition, and the second partition is sleeved on the first partition through the sliding groove and slidably connected to the first partition. Multiple weight reduction holes are also provided on the second partition on both sides of the sliding groove.

[0008] As a further optimization of this utility model, the upper sliding ring has a through hole on the side near the groove, the through hole is aligned with the limiting groove, and the limiting slider passes through the through hole through the side wall of the upper sliding ring and is slidably connected to the side wall of the upper sliding ring.

[0009] As a further optimization of this utility model, the width of the limiting groove formed between adjacent limiting plates is greater than the width of the limiting slider.

[0010] As a further optimization of this utility model, when the spring is in a compressed state, the end of the limiting slider away from the connecting rod completely slides into the through hole and does not disengage from the end of the through hole away from the limiting plate.

[0011] As a further optimization of this utility model, two guide rods are fixedly installed in the inner cavity at the bottom of the storage box, which are parallel to the limiting rod. Two guide rings are fixedly installed at the bottom of the second partition. The two guide rings are respectively sleeved on the two guide rods and can slide along the length direction of the guide rods.

[0012] The beneficial effects of this utility model are as follows: When in use, pressing the button pushes the connecting rod to slide, and the spring is compressed by the button. During the sliding process of the connecting rod, the limiting slider that is slidably connected in the through hole will slide out of the through hole until the end of the limiting slider away from the connecting rod is completely detached from the limiting groove. At this time, the user can slide the second partition along the length of the limiting rod to adjust the internal volume of the cell formed between two adjacent second partitions. This avoids the problem that the size of the bidding document storage cell in the existing bidding document classification device is mostly fixed, which is not convenient to adjust the size of the cell according to the classification needs, resulting in great inconvenience to the user.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 - Figure 6 As shown, a bidding document sorting device for construction project cost includes a storage box 1 for storing bidding documents. Both ends of the storage box 1 are fixedly connected to handles 2, which facilitates the user to move the storage box 1 containing the bidding documents.

[0023] A first partition 3 is fixedly connected to the inner cavity of the storage box 1. Multiple second partitions 4 perpendicular to the first partition 3 are slidably connected to the first partition 3. Cells for classifying and placing tender documents are formed between adjacent second partitions 4.

[0024] The second partition 4 has a sliding groove 5 in the middle section. The second partition 4 is fitted onto the first partition 3 through the sliding groove 5 and is slidably connected to the first partition 3. Multiple weight-reducing holes 6 are also provided on the second partition 4 on both sides of the sliding groove 5. The sliding groove 5 is provided so that the second partition 4 can slide along the length direction of the first partition 3 to adjust the volume of the cell formed between adjacent second partitions 4. The weight-reducing holes 6 on the second partition 4 are used to reduce the weight of the overall sorting device.

[0025] Two symmetrically arranged limiting rods 7 are fixedly installed in the inner cavity at the top of the storage box 1 along the length of the storage box 1. Grooves are opened on the side of the two limiting rods 7 that are far apart from each other. Multiple limiting plates 8 are equally spaced in the grooves, and a limiting groove 9 is formed between two adjacent limiting plates 8.

[0026] Two upper sliding rings 10 are fixedly installed on the top of the second partition 4. The two upper sliding rings 10 are respectively sleeved on the two limiting rods 7 and slidably connected to the limiting rods 7. A limiting slider 12 is slidably passed through the side wall of the upper sliding ring 10 near the groove. A through hole 11 is opened on the side of the upper sliding ring 10 near the groove. The through hole 11 is aligned with the limiting groove 9. The limiting slider 12 passes through the side wall of the upper sliding ring 10 through the through hole 11 and is slidably connected to the side wall of the upper sliding ring 10. When the limiting slider 12 slides into the limiting groove 9, it can cooperate with the limiting plate 8 to limit the upper sliding ring 10, thereby fixing the second partition 4 and the limiting rod 7 relatively.

[0027] The width of the limiting groove 9 formed between adjacent limiting plates 8 is greater than the width of the limiting slider 12, which makes it easier to insert the limiting slider 12 into the limiting groove 9.

[0028] A connecting rod 13 is fixedly connected to the end of the limiting slider 12 away from the limiting plate 8. The connecting rod 13 has a U-shaped structure. The middle section of the connecting rod 13 passes through the upper sliding ring 10 below the limiting rod 7 and is slidably connected to the upper sliding ring 10. A button 14 is fixedly connected to the end of the connecting rod 13 away from the limiting slider 12. A spring 15 is sleeved on the connecting rod 13 between the button 14 and the side wall of the upper sliding ring 10. When the spring 15 is in a compressed state, the end of the limiting slider 12 away from the connecting rod 13 slides completely into the through hole 11 and does not disengage from the end of the through hole 11 away from the limiting plate 8. When the user presses the button 14 to compress the spring 15, the limiting slider 12 slides out from the limiting groove 9 under the pushing action of the connecting rod 13, so that the user can slide the upper sliding ring 10 along the length direction of the limiting rod 7 to adjust the position of the second partition 4.

[0029] Two guide rods 16 are fixedly installed in the inner cavity at the bottom of the storage box 1, which are parallel to the limiting rod 7. Two guide rings 17 are fixedly installed at the bottom of the second partition 4. The two guide rings 17 are respectively sleeved on the two guide rods 16 and can slide along the length of the guide rods 16. They are used to guide the movement path of the second partition 4 through the guide rods 16 and the guide rings 17, so as to avoid the second partition 4 from deviating during the sliding process.

[0030] It should be noted that, in use, this construction project cost tender document classification device involves pressing button 14 to push the connecting rod 13 to slide, and compressing spring 15 by pressing button 14. During the sliding process, the connecting rod 13 will drive the limiting slider 12, which is slidably connected in the through hole 11, to slide out of the through hole 11 until the end of the limiting slider 12 away from the connecting rod 13 is completely disengaged from the limiting groove 9. At this time, the user can slide the second partition 4 along the length direction of the limiting rod 7 to adjust the internal volume of the cell formed between two adjacent second partitions 4. After adjustment, the user releases button 14. At this time, spring 15, under its own elastic force, cooperates with button 14 to pull the connecting rod 13 in the opposite direction, causing the connecting rod 13 to drive the limiting slider 12 to slide into the limiting groove 9 and insert into the limiting groove 9. At this time, the limiting slider 12 can cooperate with the limiting plates 8 on both sides to limit and fix the second partition 4, thereby completing the position adjustment of the second partition 4.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
