New description: [New technical field] This creation relates to a protective cover for fire sprinklers, in particular, a cover that is attached to the periphery of the sprinkler to protect the temperature-sensitive glass ball in the sprinkler head. element. [Previous pull] Press, the fire sprinkler heads seen in the workshops are mostly installed on the fire water supply pipelines in the building indoors adjacent to the ceiling, which can be used to sense the temperature of the sprinklers during accidental fires indoors. Designed to automatically open the valve to spray fire water, to isolate the fire source from contact with the air, and reduce the temperature of the fire source, and then extinguish the fire source. It is also known that the above-mentioned prior art sprinkler head 2 (shown in FIG. 8) forms a double rib arm 24 at a middle portion of a sprinkling valve body 21, and a seat 25 is formed at the bottom of the double rib arm 24 to lock A water return plate 23 is arranged, and a temperature sensing glass ball 22 is disposed at a middle portion of the valve body 21 so that the temperature sensing glass ball 22 is located between the double side rib arms 24; the room temperature is continuously raised to 68° in the fire zone. When C (95%~115%), the temperature-sensitive glass ball 22 will automatically rupture to release the sluice in the valve body 21, so that the water flow in the fire-fighting water pipe is vented, and the water is diffused into the water through the water return plate 23 Spraying effect. However, the temperature-sensitive glass ball in the prior art described above is often damaged by collision during the handling and installation of the sprinkler head; therefore, there is a technique of attaching a protective cover to the periphery of the sprinkler head to make the temperature-sensitive glass ball Free from damage due to collision. However, the above-mentioned prior art protective cover will cover the closed temperature-sensitive glass ball, which makes it difficult for the operator to inspect the integrity or damage of the temperature-sensitive glass ball from the outside, such as 5 M303746, which causes inconvenience in the quality inspection operation. Sex. With this in mind, the creator has developed his work to improve the above problems with his many years of experience in the manufacture and design of fire-fighting equipment. [New content] The purpose of this creation is to provide a protective cover that is detained on the periphery of the fire sprinkler head, in particular, a protective cover attached to the periphery of the temperature-sensitive glass ball in the sprinkler head to protect the temperature-sensitive glass. The ball is protected from contact damage and can be peeked into the poor state of the temperature-sensitive glass ball inside the shield. In order to achieve the above objectives, the protective cover of the present invention is made of a flexible material and has the function of facilitating the snapping or detachment of the fire sprinkler head to facilitate assembly and use. A hole for peeping is formed in the protective cover to facilitate the peeping of the temperature-sensitive glass ball. However, in order to further detail the present creation, and to exemplify the preferred embodiment, the embodiment will be described in detail as follows: ° ί [Embodiment] The first view is shown in Fig. 7, revealing the creation The three-dimensional diagram of the escort embodiment shows that the creation is mainly to install a protective cover made of flexible material on the periphery of the fire sprinkler head, and the sprinkler head 2 is paid up - the concentrated water valve body 2 The double ribs 4 are formed at the middle portion of the body, and a socket 25 is formed at the bottom of the double Hungary rib arms 24 to lock the water return plate 23, and a temperature-sensitive glass ball 22 is disposed at the middle portion of the valve ship 2i. The warm glass ball 22 is located between the double rib arms 24 at the bottom of the valve body 21 and is characterized by: ' 6

Accordingly, the protective cover i is protected by the sense of protection = the glass ball 22 is protected from collision damage, and the poor quality of the glass ball 22 can be peeked through the slot u. In the present invention, in a more specific implementation, the protective cover i is recessed with two bent portions 12 (shown in FIGS. 2 and 3) so that the protective cover i can be recessed along each of the bent portions 12. Bending, causing the section of the protective cover (as shown in the figure) to appear in the shape of the door. In addition, the above-mentioned protective cover 1 (shown in FIG. 3 and FIG. 4 ) forms a buckle 13 and a buckle hole (or buckle groove) 14 on both sides, and the buckle 13 can be fastened in the buckle hole 14 to cause protection. The cover 1 (shown in FIGS. 5 , 6 and 7 ) can be fastened between the double-sided rib arms 24 on the periphery of the temperature-sensitive glass bulb 22 by the buckle 13 and the button hole 14 .
