Description

Technical Field

[0001] The invention belongs to the construction industry, and in particular relates to an anti-theft contract storage box for construction cost. Background Art

[0002] The construction project cost generally refers to the cost of carrying out a certain project construction, that is, all the costs used from preparation to completion acceptance and delivery. The construction cost contract plays an important role in bidding, construction, filing, etc. At the same time, the construction cost contract is the privacy of the enterprise. If the construction cost contract is stolen by others, it will affect the company's operations and is not conducive to social development. Therefore, anti-theft contract storage boxes have important applications in construction cost. Existing construction cost anti-theft contract storage boxes are mostly safe-style designs, which not only take up a large space, but are also not easy to move in the later stage. At the same time, the contract in the safe is not easy to be discovered after being stolen or peeped. Summary of the Invention

Integrally formed protrusions are provided on both sides of the key, and the protrusions match the grooves.

[0009] Preferably, the tooth blocks are made of magnets, and the key is made of magnets. The polarity of the tooth block magnets is the same as that of the key magnets. The repulsive force between the tooth blocks is less than the tension of the spring, and the repulsive force between the key and the tooth blocks is greater than the tension of the spring. After the key is connected to the inner cylinder, the tooth blocks move outward and engage with the rack.

[0010] Preferably, the baffle divides the box into two parts, which are placed on the side close to the lock. At least three integrally formed partitions are provided on the baffle. A clamping spring is provided behind the baffle, which is connected to the column. The column is connected to the inner wall of the box. A sliding cylinder is provided on the column.

[0012] Compared with the prior art, the present invention has the following advantages: the present invention has a reasonable design; the driver at the movable plate must be used with a special key. If the key does not match, the tooth block moves inward under the action of the spring and is separated from the rack. The movable plate of the rotating driver will not move. At this time, if the lock is opened to open the box cover, the limit plate above the movable plate can prevent the movable plate from moving up and thus breaking the pull rope. The movable plate moves downward under the action of gravity, and the needle under the movable plate can pierce the contract to prevent the contract from being stolen or peeped, and can promptly remind people after piercing; after the special key is connected to the driver, the repulsive force of the key causes the tooth block to move outward When the cam is in motion, the gear block engages with the rack and the inner cylinder is rotated to move the movable plate away from the lock. After the movable plate enters the guide rail, it moves to the other side. The movable plate is separated from the limit plate. At this time, the lock is opened and the movable plate will contact the baffle. At the same time, the pull rope can pull the movable plate to prevent the movable plate from falling and damaging the contract. The movable plate moves to the side away from the lock to the column to push the cylinder outward. The cylinder compresses the spring sheet on the support plate to close the switch. The hydraulic cylinder contracts backward to remove the box from the base. The design of the base and the box reduces the occupied area and can move quickly. The partitions on the baffle can classify and place different types of contracts. BRIEF DESCRIPTION OF THE DRAWINGS

The driver 5 at the movable plate 4 must be used with a special key. If the key does not match, the tooth block 19 moves inward under the action of the spring 23 and separates from the rack 12. The movable plate 4 will not move when the driver 5 is turned. At this time, if the lock 3 is opened to open the box cover 2, the limit plate 17 above the movable plate 4 can prevent the movable plate 4 from moving up, thereby breaking the pull rope 13. The movable plate 4 moves downward under the action of gravity, and the puncture needle 16 under the movable plate 4 can pierce the contract to prevent the contract from being stolen or peeped, and can remind people in time after piercing. After the special key is connected to the driver 5, the repulsive force of the key 14 causes the tooth block 19 to move outward. After the tooth block 19 engages with the rack 12, the inner cylinder 20 is rotated to move the movable plate 4 away from the lock 3. After the movable plate 4 enters the guide rail 15, it moves to the other side. The movable plate 4 is separated from the limit plate 17. At this time, the lock is opened. The movable plate 4 will contact the baffle 6. At the same time, the pull rope 13 can pull the movable plate 4 to prevent the movable plate from falling and damaging the contract. When the box 1 is placed on the base 9, the hydraulic cylinder 28 is started to clamp the box 1 to prevent the box 1 from being taken away.

[0022] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
