[0009] Preferably, one side of the fixing ring is provided with an opening, and two outwardly extending connecting pieces are provided at the opening. Each of the two connecting pieces is provided with a mounting hole, and a fixing bolt is installed in the mounting hole.

[0010] Preferably, the front surface of the second protective cover is provided with a transparent window, and the transparent window is provided in correspondence with the water pressure gauge.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) By setting up a protective cover, the valve and water pressure gauge are protected inside by the first protective cover and the second protective cover, so that the valve and water pressure gauge are not exposed to the outside and external personnel cannot easily open the valve, making it safer to use. In addition, the transparent window on the second protective cover can be used to observe the value on the water pressure gauge.

[0013] (2) Regarding the above-mentioned protective cover, this utility model provides a fixing ring, which facilitates the connection between the second protective cover and the pipeline. The second protective cover and the fixing ring are detachable and can be installed, making it easier to quickly remove the protective cover during use and making it more convenient to use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, this utility model provides the following technical solution: a water spray terminal test connector for fire protection facility maintenance, including a test connector body 6 connected to a pipe 2, a valve 5 and a water pressure gauge 8 installed on the pipe 2, and a protective structure provided on the outside of both the valve 5 and the water pressure gauge 8. The protective structure includes a fixing ring 1 and a first protective cover 3 and a second protective cover 9 with a protective cavity. A locking structure is provided between the fixing ring 1 and the second protective cover 9. The first protective cover 3 can be rotatably installed with the second protective cover 9 (e.g., rotatably connected by a damping shaft) to facilitate the valve 5 entering the first protective cover 3. When the valve 5 is opened, the first protective cover 3 can be rotated upwards. The locking structure includes a slot 10 and a locking block 12 that cooperates with the slot 10. The locking block 12 is installed on one side of the fixing ring 1, and the slot 10 is opened on one side wall of the second protective cover 9.

[0023] The first protective cover 3 is installed on one side of the second protective cover 9. The bottom of the first protective cover 3 has a first opening 31, and the valve 5 is located inside the protective cavity of the first protective cover 3.

[0024] The second protective cover 9 has a second opening 91 on one side for the water pressure gauge 8 to pass through, and the water pressure gauge 8 is located inside the protective cavity of the second protective cover 9.

[0025] In response to the above, when using the fire protection facility maintenance sprinkler terminal test connector, connect pipe 2 to the fire protection facility, open valve 5, water sprays out from the test connector body 6, and water pressure gauge 8 is used to detect water pressure in order to accurately determine the performance of the fire hydrant system.

[0026] When the test connector body 6 is not in use, the fixing ring 1 is installed on the pipe 2, the water pressure gauge 8 enters the second protective cover 9 through the second opening 91, and the valve 5 is placed into the first protective cover 3 through the first opening 31. The second protective cover 9 is fixed by inserting the locking block 12 on one side of the fixing ring 1 into the locking groove 10 on the side of the second protective cover 9, thereby protecting the valve 5 and the water pressure gauge 8 and ensuring that external personnel cannot easily open them.

[0027] Specifically, in this utility model, such as Figure 1As shown, a tee pipe 4 is connected to pipe 2. The tee pipe 4 is used to connect two pipes and the test connector body 6. A two-way pipe 7 is installed on one of the pipes of the tee pipe 4. The two-way pipe 7 facilitates the installation of a water pressure gauge. The water pressure gauge 8 is installed on the top of the two-way pipe 7, and a valve is also installed on the two-way pipe 7. When using the test connector body 6, the valve is opened to test the water pressure.

[0028] Specifically, in order to facilitate the installation of the fixing ring 1 on the pipe 2, an opening is provided on one side of the fixing ring 1, and two outwardly extending connecting pieces are provided at the opening. Each of the two connecting pieces has an installation hole, and a fixing bolt 11 is installed in the installation hole.

[0029] In use, the fixing ring 1 is snapped onto the pipe 2 from the opening, or the fixing ring 1 is put onto the pipe 2 from the top or bottom, so that the fixing bolt 11 passes through the mounting hole and the fixing ring 1 is tightened to ensure the stability of the installation of the first protective cover 3 and the second protective cover 9.

[0030] In addition, such as Figure 1 and Figure 2 As shown, in this utility model, the front surface of the second protective cover 9 is provided with a transparent window 13, and the transparent window 13 is correspondingly provided with the water pressure gauge 8, so that the daily condition of the water pressure gauge 8 can be observed from the transparent window 13.
