AI Technical Summary
The metal handles of existing fire doors can easily cause secondary burns in a fire, and the locks are difficult to open when one needs to bend over or crawl during escape.
A wooden fireproof door was designed, which uses an expansion block installed in the lock groove that expands when heated. The expansion block pushes the moving plate and the lock tongue, allowing the door to be opened without turning the lock, thus avoiding secondary burns.
In a fire, the expansion block expands and pushes the latch, automatically opening the door and avoiding the risk of secondary burns from turning the lock, thus facilitating escape.

[0029] The utility model will be described in further detail below in combination with the drawings and specific embodiments:
[0030] As Figures 1-7 Indicated, a wood fireproof door, including door frame 1, the inner wall of door frame 1 is equipped with lock slot 11, lock slot 11 includes movable moving plate 12 and be used to cooperate moving plate 12 movement's sliding slot 13, and expansion block 15.
[0031] Door frame 1 is also equipped with door leaf 2, and door leaf 2 is installed with door lock 21, and door lock 21 includes telescopic lock tongue 22.
[0032] In the embodiment, fireproof door closer 3 and fireproof hinge 4 are also installed between door frame 1 and door leaf 2, and fireproof door closer 3 and fireproof hinge 4 are both installed on the back of door frame 1 and door frame 2, and fireproof door closer 3 is installed on the top end of door frame 1, wherein a part is connected with door frame 1, and another part is connected with door leaf 2.
[0033] Fireproof hinge 4 is installed on the left side of door frame 1, wherein a part is connected with door frame 1, and another part is connected with door leaf 2, and fireproof hinge 4 is used to tightly connect door frame 1 and door leaf 2, and in high temperature state, both can still maintain good stability and integrity.
[0034] Further, the shape of lock slot 11 is square, specifically similar to the shape of a puzzle with left and right "ears", and lock slot 11 is provided with symmetrically arranged sliding slots 13 at both ends, and each sliding slot 13 is provided with a spring 14, and one end of spring 14 is connected with moving plate 12.
[0035] The shape of moving plate 12 is square, and moving plate 12 can be stretched or contracted under the action of spring 14.
[0036] When lock tongue 22 is placed inside lock slot 11, moving plate 12 and spring 14 are both in the state of contraction, wherein moving plate 12 is subjected to the force applied by lock tongue 22, and the force applied by lock tongue 22 is greater than the force of spring 14, so that lock tongue 22 pushes moving plate 12 to move along lock slot 11, and spring 14 moves along with moving plate 12 during the movement of moving plate 12, so that both are in the state of contraction, and door frame 1 and door leaf 2 are in the state of complete closure.
[0037] In the embodiment, when the fire occurs, the expansion block 15 of the inner wall at the lock slot 11 of the door frame 1 expands under the action of high temperature along with the spread of the fire, and in the expansion process, the originally contracted moving plate 12 and the spring 14 are pushed by the expansion block 15 to move outside the lock slot 11 under the action of the expansion force, which is greater than the force applied by the lock tongue 22, and the moving plate 12 pushes the lock tongue 22 to move together in the moving process, and the lock tongue 22 is not placed inside the lock slot 11, at this time, the door leaf 2 is pushed at any position, and the door leaf 2 is opened, in this state, the door leaf 2 is simply closed with the door frame 1, that is, the common saying of closing.
[0038] It is ensured that the door leaf 2 can be opened by pushing in the state of bending or crawling during the escape process, so that it does not need to stand up and turn the door lock 21.
[0039] Further, the expansion block 15 is square, the diameter of the expansion block 15 is smaller than the diameter of the lock slot 11 in the normal temperature state, and the diameter of the expansion block 15 after expansion is greater than the diameter of the lock slot, wherein the expansion block 15 after expansion does not affect the lock slot 11, and the subsequent use is ensured.
[0040] The above embodiment is only used to illustrate the technical scheme of the utility model, but not to limit it; although the utility model is described in detail with reference to the foregoing embodiment, those skilled in the art should understand that the technical scheme recorded in the foregoing embodiment can be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical scheme deviate from the spirit and scope of the technical scheme of the utility model.
