Description

Technical Field

[0001] The utility model belongs to the field of protective door equipment, in particular to a new type of warehouse door. Background Art

[0002] The swing doors used for entering and exiting areas such as museum warehouses, art gallery warehouses, and archives warehouses are ordinary warehouse doors made of anti-theft doors or safe doors. Such ordinary warehouse doors are tested according to the national standard GB7106-2019, and the airtightness performance is ≤ level 4, which does not meet the airtightness requirements of warehouses with preventive protection functions.

[0003] At present, the airtightness of most museums’ cultural relics warehouses in China is poor, and a large proportion of this is because the airtightness of ordinary warehouse doors does not meet the standards. The temperature and humidity in the warehouse fluctuate greatly, which is quite unfavorable to the preservation of cultural relics and also poses a major risk to the storage of cultural relics. It does not meet the requirements of the state for preventive protection measures for cultural relics.

[0004] Because the airtightness of ordinary warehouse doors does not meet the requirements, it cannot ensure the low fluctuation requirements of constant temperature, constant humidity, clean air environment in the warehouse. Because the airtightness of ordinary warehouse doors does not meet the requirements, the constant temperature and humidity systems of most museum warehouses need to work 24 hours a day, and the overload of the electrical system increases the risk factor of the warehouse and wastes a lot of electricity resources.

[0005] However, while overcoming the defect of poor airtightness of the warehouse door, a new problem of inconvenient installation of the warehouse door has arisen.

[0006] The utility model designs a novel storehouse door to solve the above problems. Utility Model Content

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A novel warehouse door comprises a door frame, a left door leaf, a right door leaf and two door leaf inner cover plates corresponding to the left door leaf and the right door leaf respectively, the left door leaf and the right door leaf are located in the groove of the door frame, a plurality of door leaf hinges are installed on the sides of the left door leaf and the right door leaf, a plurality of inner cover plate hinges are installed on the sides of the door leaf inner cover plates, the door leaf hinges and the inner cover plate hinges are fixedly connected to the door frame through threaded fasteners, the two door leaf inner cover plates are located at the rear sides of the left door leaf and the right door leaf, the two door leaf inner cover plates are respectively connected to the left door leaf and the right door leaf through inner cover plate locks, hand wheel assemblies are installed on the left door leaf and the right door leaf, the front and rear sides of the hand wheel assemblies extend to the front sides of the left door leaf and the right door leaf and the rear sides of the door leaf inner cover plates respectively, a door lock assembly is installed on the right door leaf, and an automatic lifting threshold is installed at the bottom of the door frame.

[0009] As a preferred solution, the handwheel assembly includes a handwheel latch and an unlocking handwheel latch respectively installed on the left door leaf and the right door leaf. The front and rear ends of the handwheel latch and the unlocking handwheel latch extend to the front side of the left door leaf, the right door leaf and the rear side of the inner cover plate of the door leaf respectively and are equipped with handwheels.

[0010] As a preferred solution, a transmission mechanism is installed in the right door leaf, and the transmission mechanism is connected to the automatic lifting threshold through a chain.

[0011] As a preferred solution, the door lock assembly includes a mechanical password lock and an electronic password lock.

[0012] As a preferred solution, airtight strips are installed in the airtight grooves of the door frame and the automatic lifting threshold, and in the cover seam strip groove on the inner side of the left door leaf.

[0013] As a preferred solution, a fireproof strip groove is provided on the inner side of the door frame, and a fireproof expansion strip is installed in the fireproof strip groove, and the fireproof expansion strip covers the left door leaf and the right door leaf.

[0014] Compared with the existing technology, the advantages of the utility model are:

[0015] 1. The inner cover plate of the door leaf designed by the utility model covers the rear side of the left door leaf and the right door leaf, and is used to shield and protect the door lock, hand wheel and other related structures at the rear end of the left door leaf and the right door leaf. Therefore, the left door leaf and the right door leaf do not need to completely wrap the door lock, hand wheel and other related structures inside, so that the two door leaves can achieve the functions of high air tightness and high fire resistance with a simpler structure.

[0016] 2. The door frame and the left and right door leaves designed by the utility model are all equipped with fireproof expansion strips and airtight strips to further improve the airtightness, sound insulation, fireproofing, anti-theft and anti-explosion performance.
