Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically, it relates to a fire alarm controller protection box. Background Technology

[0002] Fire alarm controllers are the core of fire alarm engineering. Their connected smoke detectors, heat detectors, manual fire alarm buttons, audible and visual alarms, modules, and other detection and activation components all need to be connected to circuit boards for management. Modern buildings often have large-scale fire alarm point projects, and because the load-bearing capacity of each circuit is limited, each fire alarm controller requires multiple circuit boards to support the points in a large fire alarm project.

[0003] Circuit boards are typically installed inside the fire alarm controller enclosure. Due to the complex environment of the fire control room, the internal circuits of the fire alarm controller need to be protected against dust, water, and rodents. To ensure proper protection of the circuit boards, most manufacturers use boxes to house each circuit board before placing it inside the fire alarm controller. While this method offers good protection, requiring a separate protective box for each circuit board not only complicates production and assembly, but also increases production costs and occupies significant internal space with low utilization. Some manufacturers use protective covers to protect all circuit boards. However, once the protective covers are installed, removal is difficult. If a circuit board malfunctions and the cause needs to be identified, the protective cover must be removed before any repairs can be performed. Although this method reduces costs compared to using a separate protective box for each circuit board, it results in more complicated and time-consuming maintenance later on.

[0004] Therefore, a fire alarm controller protection box needs to be designed to simplify the complexity of internal circuit board production and assembly, improve the utilization rate of the protection box, and reduce the overall cost. Utility Model Content

[0005] The purpose of this utility model is to provide a fire alarm controller protection box, which mainly solves the problems of troublesome disassembly and high maintenance cost of existing circuit board protection covers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fire alarm controller protection box includes a box body, a flip platform, and a top cover; the flip platform is rotatably connected to the box body, and the top cover is rotatably connected to the box body; the top cover and the box body form a closed space to protect the flip platform; the circuit board of the fire alarm controller is mounted on the flip platform.

[0008] Furthermore, in this utility model, the box body is provided with a bottom plate and a left side plate, a right side plate, and a back plate extending upward around the outer periphery of the bottom plate. The left side plate, the right side plate, and the back plate together form a first opening. The left side plate, the right side plate, and the back plate are of the same height. The bottom plate extends forward and then upward to form a front plate. The height of the front plate is half the height of the first opening, and a groove is formed between it and the first opening. The top of the back plate extends towards the front plate to form a edging, which is used to form a seal with the top cover.

[0009] Furthermore, in this utility model, the upper cover is provided with a top plate and a left top side plate, a right top side plate, a front top side plate and a rear top side plate extending downward around the outer periphery of the top plate.

[0011] The flipping platform is installed inside the first opening, and after the flipping platform is installed, the second opening and the box form a closed space; the top cover is installed at the top of the first opening, and after the top cover is installed, it forms a closed space with the flipping platform.

[0012] Furthermore, in this utility model, the left top side plate and the right top side plate are symmetrically provided with first rotating holes at the middle end near the rear back plate, and the middle end near the front top side plate is symmetrically provided with fixing holes.

[0013] Furthermore, in this utility model, the top of the left and right upright plates are symmetrically provided with second rotating holes near the edge, the top of the left and right upright plates are symmetrically provided with fixing grooves near the wire groove, and the middle of the left and right upright plates are symmetrically provided with third rotating holes near the wire groove.

[0015] Furthermore, in this invention, the box body is rotatably connected to the top cover by screws passing through the second rotating hole and the first rotating hole.

[0016] Furthermore, in this invention, the flipping platform is rotatably connected to the box body and the flipping platform by screws passing through the third and fourth rotating holes.

[0017] Furthermore, in this utility model, the top cover is locked to the box body by means of a handle screw passing through the fixing groove and fixing hole. After the top cover is fixed, it can completely protect the fire alarm controller circuit board and other components inside the box, with only the wiring terminals exposed for external wiring.

At the same time, it greatly reduces the cost compared with the method of one circuit board and one protective box.

[0021] (3) In this utility model, screws are cleverly used to fix and flip the top cover and the flipping platform, which effectively simplifies the production process and reduces production costs. Moreover, during later maintenance, only the top cover needs to be opened to carry out the operation, which is convenient and quick. Attached Figure Description
