Description

a moisture-proof door

technical field

The utility model relates to a moisture-proof door.

Background technique

Moisture-proof door is a kind of door used for special environment, such as places that need to keep the warehouse dry, such as military industrial enterprises, places where weapons and ammunition are stored inside the army, etc., require high humidity in the warehouse, because the door is often opened and closed, so the door's Moisture-proof requirements are also high. At present, moisture-proof doors mainly make certain improvements on the door leaf. For example, the material used for the door leaf is moisture-proof and moisture-proof material, but only this can not completely achieve effective moisture-proof effect. Because the door leaf needs to be opened and closed frequently, the gap between the door leaf and the door frame seal will become larger after a long time, and the gap will become larger, resulting in a decrease in the sealing performance of the door, and moisture outside the door is easy to come in through the gap, and the moisture-proof performance is not good.

Detailed ways

Referring to Figures 1-4, a moisture-proof door of the present invention includes a door frame 1 and a door leaf 2, the door leaf 2 is hinged on the door frame 1, and a sealing strip 3 is provided at the joint surface of the door leaf 2 and the door frame 1; There are several sets of progressive locking components between the back of the door leaf 2 and the back of the door frame 1, and the upper edge, lower edge and side edges of the door leaf 2 are provided with progressive locking components. Linkage between locking components.

The linkage between the several groups of progressive locking components means that the back of the door leaf 2 is provided with a left vertical link 5.1, an upper horizontal link 5.2, a right vertical link 5.3, and a lower horizontal link 5.4. The up and down movement of the connecting rod 5.1 drives the horizontal movement of the upper horizontal connecting rod 5.2 and the lower horizontal connecting rod 5.4, and the horizontal movement of the upper horizontal connecting rod 5.2 drives the vertical movement of the right vertical connecting rod 5.3; the left vertical connecting rod 5.1, the upper horizontal connecting rod 5.2, the right vertical connecting rod 5.3 and the lower horizontal connecting rod 5.4 are provided with progressive locking components.

The horizontal movement of the upper horizontal link 5.2 and the lower horizontal link 5.4 driven by the up and down movement of the left vertical link 5.1 means that a triangular-shaped upper plate is arranged between the upper end of the left vertical link 5.1 and the left end of the upper horizontal link 5.2. Connecting frame 6.1, the upper end of upper connecting frame 6.1 is hinged with door frame 1, the left end is hinged with the upper end of left vertical connecting rod 5.1, the right end is hinged with the left end of upper horizontal connecting rod 5.2; the lower end of left vertical connecting rod 5.1 is connected with lower horizontal connecting rod 5.4 There is a lower connecting frame 6.2 of an inverted triangle shape hinged at the left end of the lower connecting frame 6.2, the lower end of the lower connecting frame 6.2 is hinged with the door frame 1, the left end is hinged with the lower end of the left vertical connecting rod 5.1, and the right end is hinged with the left end of the lower horizontal connecting rod 5.4; The horizontal movement of the rod 5.2 drives the vertical movement of the right vertical connecting rod 5.3, which means that there is a right connecting frame 6.3 in a triangular shape between the right end of the upper horizontal connecting rod 5.2 and the upper end of the right vertical connecting rod 5.3, and the upper end of the bracket is hinged with the door frame 1 , the left end is hinged with the right end of the upper horizontal link 5.2, and the right end is hinged with the upper end of the right vertical link 5.3.

The progressive locking assembly includes a locking bolt 4.1 hinged on the back of the door leaf 2. The locking bolt 4.1 can rotate vertically. The back of the door frame 1 is provided with a guide block 4.2 with an inclined surface. The locking bolt 4.1 and the guide block 4.2 The inclined surface cooperates and locks; the connection between the door leaf 2 and the door frame 1 is opened from the back to the front; the locking bolt 4.1 is hinged on the corresponding left vertical link 5.1 and upper horizontal link 5.2 , the right vertical connecting rod 5.3, the lower horizontal connecting rod 5.4.

The connection between the door leaf 2 and the door frame 1 is opened from the back to the front. As shown in Figure 2, the state diagram when the door leaf 2 is opened and viewed from the outside. Since the guide block 4.2 is designed to be inclined, when the locking bolt 4.1 contacts with the guide block 4.2, the effect of getting tighter and tighter can be achieved. The tight bolt 4.1 and the guide block 4.2 are locked a little, and the gap between the door frame 1 and the door leaf 2 can be reduced.

The inclined surface contact portion between the locking bolt 4.1 and the guide block 4.2 is designed in an arc shape. The arc design is for smoother contact between the locking bolt 4.1 and the inclined plane of the guide block 4.2.

The sealing strip 3 is integrally formed and arranged in a ring shape at the joint surface of the door frame 1 and the door leaf 2 . The gap between the two is sealed by the sealing strip 3, which plays a moisture-proof effect.

The sealing strip 3 is fixed on the sealing edge of the door leaf 2 .

The working principle of the utility model is: the door leaf 2 is closed, and the sealing strip 3 is interposed between the door leaf 2 and the joint surface of the door frame 1 to realize sealing. As shown in Figure 2, pull the locking bolt 4.1 on the left vertical link 5.1 to drive the left vertical link 5.1 to move, and the left vertical link 5.1 drives the upper horizontal link 5.2 and the lower horizontal link 5.4 to move, and the upper horizontal link The rod 5.2 drives the locking bolt 4.1 on it to lock, the upper horizontal connecting rod 5.2 drives the right vertical connecting rod 5.3 to move, the right vertical connecting rod 5.3 drives the upper locking bolt 4.1 to lock the door leaf 2, and the lower horizontal connecting rod 5.4 drives The locking bolt 4.1 on it locks the door leaf 2, and only one of the locking bolts 4.1 on the left vertical link 5.1 needs to be pulled to realize the linkage between other progressive locking components. Between the locking bolt 4.1 and the guide block 4.2, there is a multi-level locking strength (there is only one level in the prior art, which is similar to a household door lock, and there is no way if the door leaf and the door frame are loose). The smaller the gap between the door frames 1, the longer it can be used and the moisture-proof effect can still be guaranteed.

As a further improvement of the utility model, a retaining strip and a corrugated spring are provided between the inner end surface of the sealing strip 3 and the door leaf 2 . The shape of the retaining strip matches the shape of the inner surface of the sealing strip 3, and the ripple spring is located between the retaining strip and the door leaf 2. After using for a period of time, the sealing strip 3 will deform to a certain extent, which will cause the contact between the sealing strip 3 and the door frame 1 to be loose. The design of the retaining strip and the corrugated spring is to press the sealing strip 3 on the door frame tightly to improve the sealing. performance.
