Description

Technical Field

[0001] This utility model relates to the field of door closer detection technology, specifically a detection device for fire door closers. Background Technology

[0002] Fire door closers are installed on the upper part of hinged door panels or built into the door panel. They allow for one-way opening and are typically used in temperatures ranging from -20°C to 200°C. They consist of a combination of metal springs and hydraulic damping. Selection should be based on door width and weight, fire resistance rating, and frequency of use. All fire doors manufactured by the company must undergo testing.

[0003] Existing door closer testing devices use appropriate tooling to test the door closers. However, this testing method does not simulate the actual usage scenario. Only by actually installing the door closer on the door frame can the real usage condition of the door closer be detected. Therefore, it is necessary to design a testing device for fire door closers that can simulate and detect the usage condition when installed on the door panel and door frame. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a detection device for fire door closers, which solves the problem that existing detection devices for door closers use corresponding tooling to detect the door closers. However, this detection method does not simulate the usage scenario. Only when the door closer is actually installed on the door frame can the actual usage condition of the door closer be detected. Therefore, it is necessary to design a detection device for fire door closers that can simulate and detect the usage condition when installed on the door panel and door frame.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

The door closer is installed between the door frame and the door panel through the main body fixing structure and the support fixing structure.

[0008] As a preferred embodiment of the detection device for a fire door closer described in this utility model, a counterweight box is installed on the door panel, and the counterweight box contains counterweight material.

[0009] In a preferred embodiment of the fire door closer detection device of this utility model, a first mounting plate is welded to the outer wall of the counterweight box, and the first mounting plate is fixedly connected to the door panel by bolts.

[0010] As a preferred embodiment of the detection device for a fire door closer according to the present invention, the main fixing structure includes a limiting fixing seat that is bolted to the door panel, a plug-in rod is inserted into the limiting fixing seat, and a disc is welded to the end of the plug-in rod.

[0011] As a preferred embodiment of the detection device for a fire door closer described in this utility model, the limiting fixing seat has a through hole, and the plug rod is slidably connected to the inner wall of the through hole.

[0012] As a preferred embodiment of the detection device for a fire door closer according to this utility model, the plug rod can pass through the mounting hole on the main body of the door closer, and the door panel has a through hole that is directly opposite to the through hole, the diameter of the through hole being equal to the diameter of the through hole.

[0013] As a preferred embodiment of the detection device for a fire door closer according to the present invention, a spring is sleeved on the plug rod, and a first mounting ring and a second mounting ring are welded to the two ends of the spring, respectively. The first mounting ring is fixedly connected to the limiting fixing seat by bolts, and the second mounting ring is fixedly connected to the disc by bolts. The plug rod is slidably connected to the inner wall of the first mounting ring.

[0014] In a preferred embodiment of the fire door closer detection device of this utility model, a second mounting plate is welded to the outer wall of the limiting fixing seat, and the second mounting plate is fixedly connected to the door panel by bolts.

[0016] Compared with existing technologies:

[0017] By installing a door closer on a door frame and door panel, and by setting up a configuration box containing counterweights on the door panel, the state of the door closer in use can be simulated, thus achieving a truly meaningful testing purpose.

[0018] By setting a support fixing structure on the door frame and a main body fixing structure on the door panel, the main body of the door closer can be quickly fixed to the door panel and the support of the door closer can be fixed to the door frame, thereby realizing the quick assembly and disassembly of the door closer and improving the batch testing effect of the door closer.
