Description

Technical Field

[0001] The utility model relates to the field of assembly of fire-extinguishing equipment with fragile containers, in particular to a tooling for avoiding squeezing of temperature-sensitive glass bulbs. Background Art

[0002] Fire detectors in the fire protection field are divided into five categories according to the type of technical use: smoke, temperature, light, gas and composite. Among them, the temperature-sensitive self-starting gas output device is the most widely used. Chinese patent CN202220230672.1 discloses a temperature-sensitive self-starting gas output device, including a main tube, a friction ignition mechanism, a friction fire cap, a combustion chamber and a fire window. The coaxially arranged fire window, main tube and combustion chamber form a single tube structure. When the temperature-sensitive glass bulb breaks, the limit on the friction ignition mechanism is released, and the friction ignition mechanism frictionally ignites the friction fire cap and ignites the solid propellant filled in the combustion chamber. Compared with the impact ignition of the prior art, the friction ignition method is more stable and reliable. The main components are coaxially arranged, so that the overall structure is linear, the number of components is reduced, and installation and use are more convenient. However, manual assembly of the fire window, the main tube and the friction ignition mechanism is still adopted at present. During the assembly process, the fire window is connected to the main tube, the temperature-sensitive glass bulb is pressed against the friction ignition mechanism and compresses the spring. It is inevitable that the temperature-sensitive glass bulb in the fire window will have subtle cracks that are difficult to detect during the squeezing, and then fail due to the loss of liquid in the temperature-sensitive glass bulb when used.

[0021] In this embodiment, the anvil positioning hole 26 is used to insert and fix the anvil. The inner diameter of the anvil positioning hole 26 matches the diameter of the anvil. After one end of the anvil is inserted into the anvil positioning hole 26, it can prevent circumferential rotation, so that the pin hole on the anvil maintains the initial position, which facilitates the alignment of the pin hole on the anvil with the pin hole on the detection main pipe, thereby improving assembly efficiency. The structure of the anvil is the same as the abutment in the temperature-sensitive self-starting gas output device in the prior art. The anvil is a cylinder, and a pin hole passing through its axis is provided near one end.

[0023] In this embodiment, the structure of the detection main pipe is the same as the main body pipe in the temperature-sensitive self-starting gas output device in the prior art. The end of the detection main pipe connected to the combustion chamber is inserted into the detection main pipe positioning hole 38 for fixation, which can prevent the detection main pipe from rotating in the circumferential direction during the press-fitting process, so that the pin hole on the detection main pipe maintains the initial position, facilitates the alignment of the pin hole on the anvil with the pin hole on the detection main pipe, and improves the assembly efficiency.

[0024] In this embodiment, the anvil positioning hole 26 and the detection main pipe positioning hole 38 are arranged along the same axis.

[0025] In this embodiment, the pressing cap 37 is threadedly connected to the push rod 32 through a screw rod, and a limit nut 39 is provided on the screw rod of the pressing cap 37.

The U-shaped frame 21 is fixed to the base plate 1 by tightening the screws to tighten the first slider.

[0027] In this embodiment, two second slide grooves 12 are provided on the base plate 1. The second slide grooves 12 are located on both sides of the first slide groove 11 and are parallel to the first slide groove 11. A second slider is provided in the second slide groove 12. The pressing frame 31 is connected to the second slider through four screws on the base plate. The second slider can slide in the second slide groove 12.

The operating handle 33 moves the top rod 32 away from the top anvil pressing mechanism, removes the detection main pipe, and installs the fire window containing the temperature-sensitive glass bulb with the detection main pipe. During the installation process, the top anvil does not press the temperature-sensitive glass bulb to prevent the temperature-sensitive glass bulb from breaking during the assembly process.
