Description

Technical Field

[0001] This utility model relates to the field of fire damper-related products, specifically an improved fire damper that is easy to open. Background Technology

[0002] A fire damper is a type of valve that uses a shape memory alloy for temperature control and closes using gravity and a spring mechanism. Newer products also utilize the deformation of the shape memory alloy to close the valve.

[0003] However, in the current fire prevention system, the channels in the fire damper need to be sealed because a strong wind blows out during the fire. If the channels are not sealed in time, the fire will easily become more and more intense and spread everywhere, making it impossible to control in the later stages. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved, easily openable fire damper, comprising a fire damper body, a shaft rotatably connected within the fire damper body, a sealing plate fixedly sleeved on the shaft, a support frame fixedly connected to the top of the fire damper body, the top end of the shaft penetrating the fire damper body and rotatably connected to the support frame, a gear fixedly sleeved on the side wall of the shaft within the support frame, a telescopic mechanism fixedly connected to the top of one end of the fire damper body, a toothed plate fixedly connected to one end of the telescopic mechanism, one end of the toothed plate penetrating the support frame and extending inward, the toothed plate meshing with the gear at one end within the support frame, and pressure plates fixedly connected to the inner walls of both sides of the fire damper body, the two pressure plates being staggered, and the sealing plate disposed between the two pressure plates.

[0006] Preferably, a bearing block is fixedly connected to the bottom of the toothed plate near the telescopic mechanism, the fire damper body is provided with a sliding groove, a sliding rod is fixedly connected in the sliding groove, and the bearing block is slidably sleeved on the sliding rod.

[0007] Preferably, the bottom of the fire damper body is provided with a groove, a bearing is installed in the groove, and the bottom end of the shaft is fixedly inserted into the bearing.

[0008] Preferably, the support frame has a sliding opening on one side, and the toothed plate is slidably inserted into the sliding opening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-3This utility model provides an embodiment of an improved, easy-to-open fire damper, comprising a fire damper body 1, a shaft 2 rotatably connected inside the fire damper body 1, a sealing plate 3 fixedly sleeved on the shaft 2, a support frame 4 fixedly connected to the top of the fire damper body 1, the top end of the shaft 2 penetrating the fire damper body 1 and rotatably connected to the support frame 4, a gear 5 fixedly sleeved on the side wall of the shaft 2 located inside the support frame 4, a telescopic mechanism 6 fixedly connected to the top of one end of the fire damper body 1, a toothed plate 7 fixedly connected to one end of the telescopic mechanism 6, one end of the toothed plate 7 penetrating the support frame 4 and extending inward, and the toothed plate 7 located inside the support frame 4 and the gear 5... The fire damper body 1 is equipped with a gear 5 meshing mechanism. Two pressure plates 8 are fixedly connected to the inner walls of both sides of the fire damper body 1. The two pressure plates 8 are staggered. The sealing plate 3 is located between the two pressure plates 8. Specifically, the sealing plate 3 is installed inside the fire damper body 1. The sealing plate 3 is rotatably set by the shaft 2. When the fire damper body 1 needs to be closed, the telescopic mechanism 6 is activated. The telescopic mechanism 6 causes the toothed plate 7 to slide on the support frame 4. At the same time, the toothed plate 7 meshes with the gear 5 to realize the rotation of the shaft 2. The sealing plate 3 fixed on the shaft 2 will also rotate. After rotating to the position, the two ends of the sealing plate 3 will fit against the pressure plates 8 to seal the channel of the fire damper body 1.

[0020] In this embodiment, a bearing block 9 is fixedly connected to the bottom of the toothed plate 7 near the telescopic mechanism 6. A sliding groove is provided on the fire damper body 1, and a sliding rod 10 is fixedly connected in the sliding groove. The bearing block 9 is slidably sleeved on the sliding rod 10 to provide sliding support for the toothed plate 7. A groove is provided at the bottom of the fire damper body 1, and a bearing 11 is installed in the groove. The bottom end of the shaft 2 is fixedly inserted into the bearing 11 to provide rotational support for the shaft 2. A sliding opening is provided on one side of the support frame 4, and the toothed plate 7 is slidably inserted into the sliding opening. The telescopic mechanism 6 is an electric telescopic rod.

[0021] Working principle: First, a sealing plate 3 is set inside the fire damper body 1. The sealing plate 3 is rotated by the shaft 2. When the fire damper body 1 needs to be closed, the telescopic mechanism 6 is activated. The telescopic mechanism 6 causes the toothed plate 7 to slide on the support frame 4. At the same time, the toothed plate 7 meshes with the gear 5 to realize the rotation of the shaft 2. The sealing plate 3 fixed on the shaft 2 will also rotate. After rotating to the correct position, the two ends of the sealing plate 3 will fit against the pressure plate 8 to seal the channel of the fire damper body 1.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
