Description
Technical field
This utility model is related to a kind of meltable guard member, is specifically a kind of meltable bar.
Background technology
As shown in figure 1, for a kind of existing structural representation of meltable bar.The meltable bar includes fusing seat 1, the fusing
1 inner sleeve of seat is equiped with the core bar being slidably matched with it, and one end of the core bar is provided with gripper shoe 2, on the fusing seat 1 with it is described
Gripper shoe 2 is correspondingly provided with connection sheet 3, and fuse sheet 4, the two ends of the fuse sheet 4 are provided between the gripper shoe 2 and connection sheet 3
It is connected with the gripper shoe 2 and connection sheet 3 by screw respectively, the other end of the core bar stretches out outside the fusing seat and is set with
It is provided with to be provided with the nut being threadedly coupled with fusing seat 1, and the fusing seat 1 and is sleeved on core bar and for driving core bar direction
The spring of gripper shoe place end movement.Although existing meltable bar disclosure satisfy that to a certain extent use requirement,
Often there is a problem of that fuse sheet cannot be blown under the conditions of design temperature in use, that is, there is fuse sheet fusing and deposit
In the problem that the long period is delayed.
Because meltable bar is often used in the fire-fighting equipments such as fire resisting damper, if fuse sheet 4 cannot fuse in time, people's
Lives and properties are on the hazard, meanwhile, the temperature at the scene such as fire is raised rapidly, and fuse sheet 4 fuses and delayed causes fire resisting damper necessary
Could close at higher temperature, and due to the effect of expanding with heat and contract with cold caused by high temperature, fire resisting damper is at high temperature due to deformation
Act on and cannot close completely, that is, there is the situation of leakage, thus, causing defective valve of preventing fires, it is impossible to play fireproof technology
Purpose.
The content of the invention
Found by lot of experiments analysis, because gripper shoe only plays support interconnection function, its width is equal to fuse sheet width
Degree is even narrower than fuse sheet width, and when air-flow passes through, used as windward side, its front is directly heated fuse sheet, and due to propping up
The narrower width of fagging, bypass fuse sheet air-flow it is most of directly from the both sides of gripper shoe by and cannot be introduced into gripper shoe
Between fuse sheet, i.e., the back side of fuse sheet cannot be brought rapidly up, and then it is relatively slow to cause fuse sheet integrally to heat up, and cause meltable
Piece fusing is delayed.
In view of this, the purpose of this utility model is to provide a kind of meltable bar, it can be ensured that fuse sheet thermally equivalent is simultaneously
Rapid fusing.
