[0028] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0029] A sprinkler head testing device that automatically records test results, such as Figure 1-Figure 7 As shown, it includes an oil tank top plate 1 movably connected to the test box 100 and a plurality of tooling components 3 for adjusting the test sprinkler head 2. A liftable mounting plate 4 is provided above the oil tank top plate 1. The tooling component 3 is arranged on the oil tank top plate 1 and located below the liftable mounting plate 4. A photoelectric switch 5 corresponding to the tooling component 3 is provided on the liftable mounting plate 4. A sensor 6 for temperature detection and signal transmission is provided on the oil tank top plate 1 and located between the tooling components 3. The photoelectric switch 5 is used to sense the action of the tooling component 3 and transmit the action signal and test data to the PC end connected to the test box 100. A quick-connect fastener 7 is provided at one end of the tooling component 3 and is detachably connected to the sprinkler head 2 through the quick-connect fastener 7.

[0030] In the specific implementation process, the tooling assembly 3 includes a tooling body 31 with a cylindrical structure, a locking part 32 threadedly connected to the tooling body 31, a push rod 33 passing through the axis of the tooling body 31 and an elastic part 34 sleeved on the push rod 33, the push rod 33 is integrally connected with a clamping block 331, and the two ends of the elastic part 34 are respectively abutted against the clamping block 331 and the inner wall of the tooling body 31, so that the elastic part 34 drives the push rod 33 to slide downward along the tooling body 31.

[0031] Among them, the tooling body 31 is penetrated through the oil tank top plate 1, and the locking part 32 includes a first locking nut 35 and a second locking nut 36. The first locking nut 35 and the second locking nut 36 are threadedly connected to the outer wall of the tooling body 31 and the first locking nut 35 and the second locking nut 36 are abutted against the oil tank top plate 1, so as to facilitate the tooling body 31 to be firmly fixed on the oil tank top plate 1 and facilitate the adjustment of the position of the tooling body 31 relative to the oil tank top plate 1.

[0032] Furthermore, the first locking nut 35 and the second locking nut 36 have opposite thread rotation directions relative to the tooling body 31 .

[0033] In this embodiment, if Figure 4-Figure 6 As shown, the quick-connect fastener 7 includes a quick-connect male buckle 71 and a quick-connect female buckle 72. One end of the quick-connect male buckle 71 extends with a thread that is detachably connected to the tooling body 31. A rotation groove 73 is provided in the quick-connect male buckle 71. One end of the quick-connect female buckle 72 is provided with a threaded seat 74 that is threadedly connected to the sprinkler head 2. The other end of the quick-connect female buckle 72 is symmetrically provided with a quick-connect block 75. The other end of the quick-connect male buckle 71 is provided with a quick-connect groove 76 that is connected to the rotation groove 73. The quick-connect block 75 matches the quick-connect groove 76. When the quick-connect fastener 7 is quickly assembled, the quick-connect block 75 of the quick-connect female buckle 72 penetrates into the rotation groove 73 through the quick-connect groove 76 of the quick-connect male buckle 71 and then rotates 90°, thereby completing the quick-connect assembly of the quick-connect male buckle 71 and the quick-connect female buckle 72.

[0034] It should be noted that one end of the push rod 33 passes through the quick-connect male buckle 71 and the quick-connect female buckle 72 and abuts against the sealing ring of the sprinkler head 2, and the other end of the push rod 33 protrudes from the tooling body 31 and maintains a distance from the photoelectric switch 5 to facilitate triggering the photoelectric switch 5.

[0035] In the specific implementation process, an oil tank 101 for containing heat transfer oil is provided in the test box 100 , and a tray 102 for collecting test residues of the sprinkler head 2 is provided at the bottom of the oil tank 101 .

[0036] Furthermore, one end of the push rod 33 close to the photoelectric switch 5 is threadedly connected with a travel start-stop cap 332 for limiting the sliding distance of the push rod 33 after the sprinkler head 2 is actuated.

[0037] During the operation of the test device, the test box 100 is externally connected to the PC end, and the internal heat transfer oil is loaded through the oil tank 101 so that the sprinkler head 2 is heated evenly, and the tray 102 is used to collect the residues of the thermal sensitive element after the sprinkler head 2 is actuated. The sprinkler head 2 is threadedly connected to the threaded seat 74 so that it can be quickly assembled on the tooling assembly 3 through the quick-connect male buckle 71 and the quick-connect female buckle 72, wherein the quick-connect male buckle 71 is threadedly connected to the tooling body 31, and the tooling assembly 3 is locked on the oil tank top plate 1 through the first locking nut 35 and the second locking nut 36, and the vertical position of the tooling assembly 3 relative to the oil tank top plate 1 is adjusted by the first locking nut 35 and the second locking nut 36, so as to unify the thermal sensitive elements of sprinkler heads 2 of different models. The horizontal position of the parts is adjusted so that the thermistors of several sprinkler heads 2 can maintain the same height in the oil tank 101 to achieve the test temperature of synchronous heating. After the sprinkler head 2 is assembled with the tooling assembly 3, the sprinkler head 2 lifts the top rod 33. After the thermistor of the sprinkler head 2 is activated by the high temperature, the thermistor breaks and the top rod 33 slides down, so that the corresponding photoelectric switch 5 is activated. Then the photoelectric switch 5 cooperates with the sensor 6 to send signal data to the PC end to record the action time and action temperature. During the test, the sensor 6 monitors the temperature value in real time and uploads it. The PC end draws a temperature-time curve according to the collected data information, and automatically records the temperature value when each photoelectric switch 5 is activated (that is, the thermistor is activated and the top rod 33 drops).

[0038] The number of the tooling assemblies 3 is 20, and the 20 tooling assemblies 3 are arranged in a 4×5 matrix relative to the oil tank top plate 1, so as to complete the test in batches and improve the test efficiency.

[0039] The quick-connect block 75 and the quick-connect female buckle 72 are integrally formed, and the outer wall of the quick-connect male buckle 71 is provided with knurling.

[0040] In summary, the present invention has the following beneficial effects: the present invention discloses a sprinkler head test device that automatically records test results, a liftable mounting plate 4 is provided above the oil tank top plate 1, a tooling assembly 3 is provided on the oil tank top plate 1 and below the liftable mounting plate 4, a photoelectric switch 5 corresponding to the tooling assembly 3 is provided on the liftable mounting plate 4, a sensor 6 for temperature detection and signal transmission is provided on the oil tank top plate 1 and between the tooling assembly 3, the photoelectric switch 5 is used to sense the action of the tooling assembly 3 and transmit the action signal and test data to the PC end connected to the test box 100, and a quick-connect fastener 7 is provided at one end of the tooling assembly 3 and is detachably connected to the sprinkler head 2 through the quick-connect fastener 7. That is, through this setting, highly intelligent batch testing work is realized, and the accuracy, operability and reliability of the sprinkler head test are improved.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
