[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides a technical solution: a device for storing engineering cost bid documents, comprising a storage cabinet 1, a cabinet door 2 and a placement plate 4. The cabinet door 2 is installed on the outside of the storage cabinet 1, and an observation window 3 is embedded in the middle of the cabinet door 2. Placement plates 4 are arranged at equal intervals inside the storage cabinet 1, and a connecting plate 5 is provided on the inner wall of the storage cabinet 1 close to the placement plate 4. A movable cavity 6 is opened inside the connecting plate 5, and a limit plate 7 is provided above the placement plate 4, and a movable block 8 is connected to one side of the limit plate 7, and the movable block 8 is connected to the inside of the movable cavity 6.

[0022] A guide rod 9 passes through the middle of the movable block 8, and both ends of the guide rod 9 are connected to the inner wall of the movable cavity 6. A spring 10 is sleeved on the outer side of the guide rod 9; one end of the spring 10 is connected to the inner wall of the movable cavity 6, and the other end of the spring 10 is connected to the movable block 8. The movable cavity 6 is symmetrically distributed about the center line of the connecting plate 5. The movable block 8 forms a telescopic structure with the movable cavity 6 through the spring 10, and the limit plate 7 is symmetrically distributed about the center line of the placement plate 4.

[0023] During specific implementation, in the initial state, the two limit plates 7 are close to both ends of the placement plate 4. When it is necessary to save the engineering cost tender document, first pull the limit plate 7 outwards. The pulled limit plate 7 drives the connected movable block 8 to move synchronously. While the movable block 8 moves inside the movable cavity 6 along the guide rod 9, it squeezes the spring 10 sleeved outside the guide rod 9. Then, place the engineering cost tender document to be saved correspondingly above the placement plate 4, and then loosen the pulled limit plate 7. The loosened limit plate 7 can automatically reset inwards through the elastic force of the spring 10, making the inner side of the limit plate 7 fit against the surface of the tender document. By setting the retractable and movable limit plate 7 above the placement plate 4, the engineering cost tender document can be clamped and limited, preventing the tender document from being scattered during storage, so that the engineering cost tender document storage device has a limiting structure.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 4 , a movable plate 11 is provided below the placement plate 4, and a connecting seat 12 is provided in the middle of the surface of the movable plate 11. An installation frame 13 is provided on the connecting seat 12; the installation frame 13 is connected to the lower surface of the placement plate 4. A threaded rod 14 passes through the middle of the connecting seat 12, and the top end of the threaded rod 14 is connected to the installation frame 13 through a bearing seat; a knob 15 connected to the threaded rod 14 is provided inside the installation frame 13. Fixed seats 16 are provided on both sides of the placement plate 4 close to the installation frame 13; a connecting pin 17 passes through the middle of the fixed seat 16, and the bottom end of the connecting pin 17 is connected to the surface of the movable plate 11. The threaded rod 14 and the connecting seat 12 are in threaded connection, and the connecting pins 17 are symmetrically distributed about the center line of the movable plate 11.

[0025] During specific implementation, the distance between the movable plate 11 and the placement plate 4 is the smallest in the initial state. By turning the knob 15, the connected threaded rod 14 is rotated synchronously. Since the threaded rod 14 and the connecting seat 12 are in threaded connection, as the threaded rod 14 rotates, the outer connecting seat 12 can drive the movable plate 11 to move downwards. The downward-moving movable plate 11 drives the two connecting pins 17 to move downwards synchronously. The downward-moving connecting pins 17 stably move downwards along the inside of the fixed seat 16 until the movable plate 11 moves down to the limit position. At this time, the distance between the movable plate 11 and the placement plate 4 is the largest, and the staff can place the corresponding documents above the movable plate 11. By setting the movable plate 11 that can descend below the placement plate 4, the placement area is increased, so that the engineering cost tender document storage device has an auxiliary storage structure.

[0026] In summary, when using this device for storing engineering cost tender documents, first move the storage cabinet 1 to the designated working area, and open the cabinet door 2. When placing the documents, first pull the limiting plate 7 outwards to the extreme position, then place the engineering cost tender documents to be stored correspondingly above the placing plate 4, and then loosen the pulled limiting plate 7 so that the inner side of the limiting plate 7 fits against the surface of the tender documents, clamping and limiting the engineering cost tender documents through the limiting plate 7 to prevent the tender documents from being scattered during storage. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
