Description

Technical Field

[0001] This utility model relates to the field of fire door technology, and in particular to a lock box for fire doors. Background Technology

[0002] Fire doors are a type of door, and their function is the same as ordinary doors, providing separation and protection. However, unlike other doors, fire doors also prevent the spread of fire and smoke, stopping the fire from spreading for a certain period of time and ensuring the evacuation of people. If fire doors are installed, they play a crucial role in suppressing the spread of fire and protecting the safe evacuation of people during a fire.

[0003] In existing technologies, fire doors generally do not use lock boxes. The fire door core panel can easily affect the lock and cause the lock to shift. Some lock boxes that house the lock are more complicated to install with the door, requiring the four corners of the lock to be fixed sequentially, which reduces the overall linkage of the device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. By rotating the two limiting plates on the outer wall of the rotating rod, the limiting plates and slots are staggered and placed in the limiting groove. By utilizing the cooperation between the limiting groove and the limiting plate, the box and door can be quickly installed, bringing certain convenience to people. This is the proposed lock box for fire doors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lock box for a fire door includes a door body with an installation groove. A box is located at the front end of the door body, which mates with the installation groove. The box has two placement slots, each containing a lock body. A limiting frame is provided on the outer wall of the box, and multiple symmetrically arranged rotating rods are rotatably connected through the limiting frame. Each of the rotating rods has a connecting mechanism on its outer wall for connection. The door body has a cooperating mechanism that mates with the connecting mechanism.

[0007] Preferably, the connecting mechanism includes two limiting plates disposed on the outer wall of the rotating rod, and the two limiting plates are symmetrically arranged.

[0008] Preferably, the mating mechanism includes a plurality of symmetrically arranged slots on the door body, the slots mating with a rotating rod and two limiting plates, the inner wall of the slots having a limiting groove, and both limiting plates mating with the limiting groove.

[0009] Preferably, two symmetrically arranged linkage rods are rotatably connected between the inner walls on both sides of the limiting frame. Both ends of the two linkage rods are provided with driven worm gears on their outer walls, and the outer walls of the plurality of rotating rods are provided with driven worm wheels that cooperate with the driven worm gears.

[0010] Preferably, a transmission rod is rotatably connected between the box body and the limiting frame, and bevel gears are provided at both ends of the transmission rod and on the outer walls of the two linkage rods, meshing with each other.

[0011] Preferably, an operating rod is rotatably connected to the front end of the box body, an active worm gear is provided on the outer wall of the operating rod, and an active worm wheel that cooperates with the active worm gear is provided on the outer wall of the transmission rod.

[0012] The beneficial effects of this utility model are:

[0013] 1. By rotating the two limiting plates on the outer wall of the rotating rod, the limiting plates are staggered with the slot and placed in the limiting groove. The cooperation between the limiting groove and the limiting plate enables the quick installation of the box and the door, bringing certain convenience to people.

[0014] 2. By setting up the cooperation between the driving worm and the driving worm wheel, the meshing of two sets of bevel gears, and the cooperation between multiple sets of driven worms and driven worm wheels, the rotation of multiple rotating rods can be achieved when the operating rod is rotated, thereby improving the overall linkage of the device.

[0021] Reference Figure 1-3 A lock box for fire doors includes a door body 1, an installation groove 2 on the door body 1, a box body 5 at the front end of the door body 1, the box body 5 cooperating with the installation groove 2, two placement grooves 6 on the box body 5, each containing a lock body 7, a limiting frame 8 on the outer wall of the box body 5, and multiple symmetrically arranged rotating rods 9 rotatably connected through the limiting frame 8, each rotating rod 9 having a connecting mechanism on its outer wall for connection, the connecting mechanism including two limiting plates 10 on the outer wall of the rotating rods 9, the two limiting plates 10 being symmetrically arranged, by rotating the two limiting plates 10 on the outer wall of the rotating rods 9, the limiting plates 10 intersect with the slot 3 and are located within the limiting groove 4, the cooperation of the limiting groove 4 and the limiting plates 10 enables quick installation of the box body 5 and the door body 1, bringing convenience to people.

[0022] The door body 1 is provided with a cooperating mechanism that works with the connecting mechanism. The cooperating mechanism includes multiple symmetrically arranged slots 3 on the door body 1. The slots 3 cooperate with the rotating rod 9 and two limiting plates 10. The inner wall of the slots 3 is provided with limiting grooves 4, and both limiting plates 10 cooperate with the limiting grooves 4.

[0023] Two symmetrically arranged linkage rods 16 are rotatably connected between the inner walls on both sides of the limiting frame 8. Both ends of the linkage rods 16 are provided with driven worm gears 17. The outer walls of multiple rotating rods 9 are provided with driven worm wheels 18 that cooperate with the driven worm gears 17.

[0024] A transmission rod 14 is rotatably connected between the box 5 and the limiting frame 8. Both ends of the transmission rod 14 and the outer walls of the two linkage rods 16 are provided with bevel gears 15, which mesh with each other.

[0025] An operating rod 11 is rotatably connected to the front end of the box 5. The outer wall of the operating rod 11 is provided with a driving worm gear 12, and the outer wall of the transmission rod 14 is provided with a driving worm wheel 13 that cooperates with the driving worm gear 12. By setting the cooperation between the driving worm gear 12 and the driving worm wheel 13, the meshing of two sets of bevel gears 15, and the cooperation between multiple sets of driven worm gears 17 and driven worm wheels 18, the rotation of multiple rotating rods 9 can be realized when the operating rod 11 is rotated, thereby improving the overall linkage of the device.

[0026] When using this utility model, during the installation of the box body 5, multiple rotating rods 9 on the limiting frame 8 on the outer wall of the box body 5 are inserted into multiple slots 3 respectively. Rotating the operating rod 11 causes the active worm gear 12 on the outer wall of the operating rod 11 to rotate. Utilizing the cooperation between the active worm gear 12 and the active worm wheel 13, the active worm wheel 13 rotates, driving the transmission rod 14 to rotate. Then, utilizing the meshing of the two pairs of bevel gears 15 between the transmission rod 14 and the two linkage rods 16, the two linkage rods 16 rotate. Consequently, the driven worm gears 17 on the outer walls at both ends of the linkage rods 16 rotate. Utilizing the cooperation between the driven worm gear 17 and the driven worm wheel 18, the driven worm wheel 18 rotates, driving the rotating rod 9 to rotate. This causes the two limiting plates 10 on the outer wall of the rotating rod 9 to rotate, so that the limiting plates 10 and the slots 3 are interlaced and positioned within the limiting grooves 4. Utilizing the cooperation between the limiting grooves 4 and the limiting plates 10, the box body 5 and the door body 1 can be quickly installed, bringing convenience to people.
