Referring to fig. 1-9, a double-layer sealing door for a three-way comprehensive test box comprises a double-door 1 for sealing the outer side of a test box 101 of the test box 100 and a double-door 2 arranged on the inner side of the test box 101, wherein the double-door is hinged with the test box 100.

The height of the inner double door 2 is lower than the height of the outer double door 1 and higher than the maximum water filling height of the test chamber 100. When water is injected into the three-in-one test box 100, the independent inner double-door 2 can block 80% -90% of water injection pressure, the outer double-door 1 can block 10% -20% of water injection pressure, the double-layer sealing door is utilized to resist the water injection pressure, the water leakage in the water injection process is effectively reduced, the sealing performance is good, and the problem that the bottom of the door body is easy to deform and the sealing performance cannot be guaranteed when the single-layer double-door resists the water injection pressure is solved.

The height of the inner side double door 2 is lower than that of the outer side double door 1, so that the material cost can be saved, the weight is reduced, and the door can be conveniently opened and closed.

To ensure stable sealing of the double seal door, the design is also made from the fixed lock of the door and the seal between the door and the test chamber 100.

The fixed lockset has the following structure:

the two outer doors 11 of the outer double door 1 and the two inner doors 21 of the inner double door 2 are detachably connected through a transverse lock 3, the transverse lock 3 adopts a roller tightening handle, the roller tightening handle is arranged on the inner side wall of the doors (see figure 6), and the handle is rotatably arranged on the outer side wall of the doors (see figure 5); the transverse locks 3 connected between the two inner doors 21 are not shown in the figures, and are identical in construction to the transverse locks 3 on the outer doors 11.

One of the outer doors 11 is detachably connected with the test box 100 through a longitudinal lock 4, the longitudinal lock 4 adopts a stainless steel connecting rod type world lock, the stainless steel connecting rod type world lock is arranged on the inner side wall of the outer door 11 and is used for locking the outer door 11 and the frame of the box opening 101 of the test box 100 at the top of the outer door 11 together.

The inner side double door 2 and the outer side double door 1 are outward turning doors, so that the test box 100 can conveniently move back and forth, and a test piece in the test box can enter and exit from the box opening 101.

When the door is closed, the two inner doors 21 are fixed through a roller tightening handle, then one outer door 11 with a stainless steel connecting rod type top-bottom lock is closed, the outer door 11 is locked with the frame at the top of the box opening 101 through the stainless steel connecting rod type top-bottom lock, finally the other outer door 11 is closed, and the two outer doors 11 are locked and fixed through the roller tightening handle.

The bottoms of the transverse lockset 3 and the longitudinal lockset 4 do not exceed the bottom edge of the box door, so that after the test box 100 descends, the opening 102 at the bottom of the test box is matched with the lower sealing bottom plate 200 (a blind plate, a vertical transition bottom plate or a horizontal transition bottom plate), the lower sealing bottom plate 200 is bonded and sealed with the bottom end surface of the double-layer sealing door, and the lower sealing bottom plate 200 is made of polyurethane foam materials.

The sealing structure is designed as follows:

the two outer doors 11 are matched through the first spigot structure 12, the two inner doors 21 are matched through the second spigot structure 22, and the waterproof sealing effect between the door gaps is improved through the spigot structure.

A step surface 13 is formed at the edge where the outer box door 11 is attached to the test box 101, the tread surface of the step surface 13 is attached to the inner wall of the test box 101, and the elevation surface of the step surface 13 is attached to the outer edge of the test box 101; an outer sealing structure 14 is arranged between the tread and the matching surface of the first spigot structure 12, and the outer sealing structure 14 is a sealing rubber strip. The design of the step surface 13 increases the waterproof sealing effect between the box door and the test box 101, and the sealing rubber strip is added, so that the sealing effect can be further improved.

An inner sealing structure 23 is arranged between the two side edges and the bottom edge of the inner box door 21 and the matching surface of the second spigot structure 22; the inner sealing structure 23 is an inflatable rubber strip. The two side edges of the inner box door 21 are sealed with the test box 101 through the inflatable rubber strips, and the bottom edge of the inner box door 21 is also sealed with the lower sealing bottom plate through the inflatable rubber strips, so that the sealing of the two side edges and the bottom edge of the inner box door 21 is enhanced.

In order to facilitate the observation of the liquid level, the outer side double door 1 is provided with a transparent observation window 15, and the transparent observation window 15 is located above the inner side double door 2 and corresponds to a liquid level scale in the box body of the test box 100, so that the liquid level data can be directly read from the liquid level scale, and the water injection level can be controlled in time, or other emergency situations can be dealt with.

The above embodiments are provided to illustrate the technical concept and features of the present utility model and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same, and are not intended to limit the scope of the present utility model. All equivalent changes or modifications made in accordance with the spirit of the present utility model should be construed to be included in the scope of the present utility model.
