Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for building doors and windows, specifically a waterproofing device for steel doors. Background Technology

[0002] When a city's drainage system cannot keep up with the rate of water accumulation, large-scale flooding can easily occur. When buildings have large openings, such as open-plan shops, effective waterproofing cannot be implemented quickly enough, often leading to internal flooding and damage. Waterproof doors are commonly used in areas prone to flooding and waterlogging to prevent water from seeping into buildings.

[0003] Traditional steel doors rely mainly on sealing strips between the door frame and the door leaf for waterproofing. However, after long-term use, these strips are prone to deformation or aging, leading to water leakage. They are especially ineffective in preventing water accumulation during heavy rain or floods. Some solutions use welded fixed water-blocking plates, but these are inconvenient to disassemble and difficult to maintain, and cannot be adapted to different door frame sizes. Utility Model Content

[0008] Preferably, the waterproofing mechanism consists of multiple linear arrays of waterproof strips, which are continuously arranged along the circumference of the baffle.

[0009] Preferably, both of the triangular plates are welded to the door frame, and a waterproof coating is applied to the weld between the triangular plates and the door frame.

[0010] Preferably, the quick pressing device includes a mounting plate, a support member protruding from the mounting plate, a pull rod connected to the support member, two mutually symmetrical connecting members rotatably mounted on the pull rod, an abutment rod connected to the other end of the two connecting members, a limiting sleeve protruding from the support member, and the abutment rod slidably arranged within the limiting sleeve.

[0011] Preferably, the bottom end of the abutment rod is covered with a rubber anti-slip sleeve.

[0014] Compared with the prior art, this utility model provides a waterproof device for steel doors, which has the following advantages: This utility model forms a continuous sealing layer by tightly fitting the waterproof strips arranged around the baffle with the track, which can effectively prevent water seepage. Furthermore, the baffle can be flexibly replaced through the cooperation of the track and the quick-pressing device. The uniform pressure of the quick-pressing device can ensure the connection stability between the baffle and the track while quickly completing the installation and removal of the baffle.

[0024] Please see Figure 1-5 A waterproofing device for a steel door includes a door frame 2 and a baffle 3 embedded in a wall 1. Two symmetrical triangular plates 6 are provided on the inner side of the door frame 2. The same locking rail 5 is welded on the two triangular plates 6. The baffle 3 is snapped between the two locking rails 5. A quick-pressing device 7 is detachably connected to both triangular plates 6. Two symmetrical handles 4 are protruding from the top of the baffle 3. A waterproofing mechanism is provided on the baffle 3.

[0025] The waterproof strips 8 arranged around the baffle 3 are tightly bonded to the rail 5 to form a continuous sealing layer, which can effectively prevent water seepage. Furthermore, the baffle 3 can be flexibly replaced through the cooperation of the rail 5 and the quick-pressing device 7. The uniform pressure of the quick-pressing device 7 can ensure the connection stability between the baffle 3 and the rail 5 while quickly completing the installation and disassembly of the baffle 3.

[0026] Specifically, in this embodiment, the waterproof mechanism consists of multiple linear arrays of waterproof strips 8. The waterproof strips 8 are continuously arranged along the circumference of the baffle 3. Through the continuous arrangement of the waterproof strips 8, the baffle 3 can be squeezed and deformed after it abuts against the rail 5, thereby forming multiple sealing layers and further ensuring the waterproof effect of the waterproof mechanism.

[0027] Specifically, in this embodiment, both triangular plates 6 are welded to the door frame 2, and a waterproof coating is applied to the weld between the triangular plates 6 and the door frame 2 to ensure the waterproofness between the door frame 2 and the triangular plates 6.

[0028] Specifically, in this embodiment, the quick pressing device 7 includes a mounting plate 71, a support member 72 protruding from the mounting plate 71, a pull rod 74 connected to the support member 72, two mutually symmetrical connecting members 73 rotatably mounted on the pull rod 74, an abutment rod 75 connected to the other end of the two connecting members 73, a limiting sleeve 76 protruding from the support member 72, and the abutment rod 75 slidably arranged within the limiting sleeve 76.

[0029] Pulling the lever 74 causes the connecting piece 73 to drive the abutment rod 75 to move axially along the limiting sleeve 76, thereby achieving the pressing and releasing of the baffle 3.

[0030] Specifically, in this embodiment, the bottom end of the abutment rod 75 is covered with a rubber anti-slip sleeve, which can ensure the pressing stability of the abutment rod 75 on the baffle 3.

[0031] Specifically, in this embodiment, the mounting plate 71 is fixed to the triangular plate 6 by four bolts arranged in a matrix, so as to realize the quick assembly and disassembly of the mounting plate 71.

[0032] Specifically, in this embodiment, the width of the rail 5 is adapted to the baffle 3, and the track depth of the rail 5 is less than the maximum stroke range of the abutment rod 75. After the quick pressing device 7 is pulled to release the pressing of the baffle 3, the baffle 3 can be tilted outward and removed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
