Description

A temperature-controlled release device for a fireproof roller shutter with a high-torque roller structure Technical Field

[0001] This utility model relates to the field of fireproof roller shutter technology, and more specifically, it relates to a temperature control release device for fireproof roller shutters with a high torque roller structure. Background Technology

[0002] Fireproof roller shutter temperature control release devices generally use steel wire ropes to pull the brake lever of the fireproof roller shutter motor, causing the brake pads of the fireproof roller shutter motor to separate from the transmission mechanism. The fireproof roller shutter then closes by its own weight. Existing fireproof roller shutter temperature control release devices control opening and closing by pulling a lever with a steel rope, which has poor pulling effect, lacks a suitable and efficient adjustment mechanism, and makes the installation and removal of the steel rope cumbersome and inconvenient. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a temperature control release device for fireproof roller shutters with a high-torque roller structure, in order to solve the technical problems mentioned in the background art, such as the poor pulling effect of achieving opening and closing control by pulling a knocking rod with a steel rope and the lack of a suitable and efficient adjustment mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temperature-controlled release device for a fireproof roller shutter with a high-torque roller structure, comprising a fixing plate, a temperature-controlled release device body on the fixing plate, a steel rope running through the temperature-controlled release device body, a gripping ring on the steel rope, a detachable mounting base on the steel rope, through holes symmetrically opened on the mounting base corresponding to the steel rope, a through groove opened on the mounting base, a striking rod inside the through groove, a roller body on the striking rod corresponding to the steel rope, and a groove opened on the roller body corresponding to the steel rope.

[0005] The present invention is further configured such that the fixing plate has fixing holes, and multiple fixing holes are provided to realize the installation of the fixing plate.

[0006] The present invention is further configured such that the mounting base has multiple mounting holes to enable mounting of the mounting base.

[0007] The present invention is further configured such that a limiting seat is detachably provided on the steel rope, a limiting hole is provided on the limiting seat, a limiting rod is provided inside the limiting hole, and the limiting rod and the limiting hole are threadedly connected for easy disassembly and assembly.

[0008] The present invention is further provided with a retaining ring on the knocking rod corresponding to the through groove. Two retaining rings are provided to limit the installation of the knocking rod and prevent it from falling off.

[0009] Compared with the prior art, this utility model provides a temperature control release device for fireproof roller shutters with a high-torque roller structure, which has the following beneficial effects:

[0010] 1. Through the design of the roller body, the position of the knocking rod with the roller body relative to the through groove is adjusted. The steel rope is pulled, which drives the knocking rod with the roller body to rise and fall relative to the through groove, realizing the prying operation of the external braking components, achieving efficient opening and closing, and improving opening and closing efficiency.

[0011] 2. Through the design of the limiting seat, the steel rope is installed in two corresponding through holes, the limiting seat is installed at the end of the steel rope, the limiting rod and the limiting hole are threaded together, and the limiting rod and the limiting seat are engaged to limit the installation of the steel rope, which facilitates quick assembly and disassembly.
