[0031] 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.

[0032] Reference Figure 1This utility model provides an embodiment of an automatic fire sprinkler system, including a sprinkler head 1. The sprinkler head 1 has a temperature sensing component inside, which can automatically spray water at high temperatures, thus achieving the effect of automatic sprinkler spraying. This is prior art. A water pipe a2 is provided at the bottom end of the sprinkler head 1, and a sealing ring is provided at the bottom end of the water pipe a2 to ensure the sealing performance when the water pipe a2 slides up and down on the inner wall of the water pipe b3. The bottom end of the water pipe a2 is slidably connected to the water pipe b3, and the inner diameter of the water pipe b3 corresponds to the outer diameter of the water pipe a2. A three-way pipe 4 is fixedly connected to the bottom end of the water pipe b3, which serves to transport water. This is prior art. A height adjustment mechanism 5 is provided on the side wall of the water pipe b3.

[0033] Reference Figures 1-3 The height adjustment mechanism 5 includes a fixed base 51, which is fixedly connected to the outer side wall of the water pipe b3. A lever 52 is slidably connected to the bottom end of the outer wall of the fixed base 51. Connecting rods 53 are fixedly connected to both sides of the top end of the lever 52. The function of the lever 52 is that when the height of the water pipe a2 needs to be adjusted, the construction personnel can push the lever 52 to release the limiting function. A sliding groove is opened at the bottom end of the fixed base 51, and the connecting rod 53 passes through and is slidably connected to the inner wall of the sliding groove. The sliding groove plays a guiding role for the movement of the connecting rod 53, so that the connecting rod 53 can move smoothly. Rod 53 can only move laterally in a straight line within the inner wall of the slide groove. The side wall of the sliding sleeve 56 has a slot, through which the connecting rod 53 passes and is slidably connected to the inner wall of the slot in the sliding sleeve 56. Both sets of connecting rods 53 are elastically connected to the inner side wall of the fixed seat 51 via springs 54. One end of the spring 54 is fixedly connected to the side wall of the connecting rod 53, and the other end is fixedly connected to the inner side wall of the fixed seat 51. The function of the spring 54 is to allow for reset. When the height of water pipe a2 needs to be adjusted, the construction worker pulls the lever 52 to move it, which will simultaneously... The moving connecting rod 53 moves laterally synchronously. While moving, the connecting rod 53 compresses the spring 54, thus disengaging the connecting rod 53 from the sliding rod 55, thereby unlocking and allowing height adjustment. At the desired height, the spring 54 resets the connecting rod 53, causing it to re-engage with the slot of the sliding rod 55. The end of the connecting rod 53 furthest from the spring 54 is connected to the sliding rod 55. The side wall of the sliding rod 55 has multiple sets of slots, through which it can engage with the connecting rod 53, thus enabling the connection of water pipes. 2. For height adjustment, the sliding rod 55 is fixedly connected to the outer side wall of the water pipe a2. The outer wall of the sliding rod 55 is slidably connected to the sliding sleeve 56. The sliding sleeve 56 has a groove. The sliding sleeve 56 plays a guiding role for the sliding rod 55, so that the sliding rod 55 can only slide on the inner wall of the groove, thereby ensuring the stability of the movement when the height of the water pipe a2 is adjusted. The top of the sliding sleeve 56 is fixedly connected to the outer side wall of the fixed seat 51. The sliding sleeve 56 is fixedly connected to the outer side wall of the water pipe b3. The outer wall of the tee pipe 4 is provided with an adjustable installation component 6.

[0034] Reference Figure 2 - Figure 4 The adjustable mounting assembly 6 includes a connecting seat 61, which is fixedly connected to the outer wall of the tee pipe 4. The inner wall of the connecting seat 61 has a groove, and a slider 62 is slidably connected to the inner wall of the groove. The groove guides the slider 62, allowing it to slide only within the inner wall of the groove. The side wall of the slider 62 has an internal thread groove, which allows for threaded connection with flanges on other water pipes. The movement of the slider 62 and the internal thread groove achieves adjustable mounting. A protruding rod 63 is fixedly connected to the side wall of the slider 62, and a rotating disk 64 is slidably connected to the outer wall of the protruding rod 63. The surface of the rotating disk 64 has multiple sets of inclined grooves, and the protruding rod 63 has multiple sets of grooves. The inclined grooves guide the protruding rod 63, allowing it to move linearly only within the inner wall of the inclined groove. The rotating disk 64 rotates the slider 62. The multiple sets of protruding rods 63 move linearly along the inner wall of the inclined groove, causing the slider 62 to move linearly along the inner wall of the groove of the connecting seat 61. The rotating disk 64 is rotatably connected to the outer wall of the tee pipe 4. The surface of the rotating disk 64 has an internal thread groove, and a bolt 65 is threadedly connected to the internal thread groove of the rotating disk 64. The threaded ring of the bolt 65 contacts the outer wall of the tee pipe 4. The function of the bolt 65 is to move within the internal thread groove of the rotating disk 64 after the slider 62 has been adjusted and connected to other water pipes. When the bolt 65 is rotated, it moves within the internal thread groove of the rotating disk 64, so that when the threaded ring of the bolt 65 contacts the outer wall of the tee pipe 4, the slider 62 is initially locked in place. The threaded fit between the two has self-locking properties. A handle 66 is fixedly connected to the surface of the rotating disk 64. By pulling and pushing the handle 66, the rotating disk 64 can be controlled to rotate.

[0035] Working Principle: When installing the automatic sprinkler system, if the height of water pipe a2 needs to be adjusted, first move the lever 52 outward. This causes the connecting rod 53 to move laterally in a straight line. Simultaneously, the connecting rod 53 compresses the spring 54, thus disengaging the connecting rod 53 from the slot of the sliding rod 55, thereby releasing the lock. The installer then adjusts the height of water pipe a2. Once the desired height is reached, the lever 52 is released, and the spring 54 resets the connecting rod 53, pushing it to move again and re-engage with the slot of the sliding rod 55, thus locking the current height position.

[0036] Before adjusting the height of water pipe a2, when the tee pipe 4 needs to be connected to the main pipe, the construction worker first rotates the rotating disk 64 by the handle 66. The inclined groove on the surface of the rotating disk 64 will guide the movement of the convex rod 63 of the slider 62, so that the convex rod 63 slides on the inner wall of the inclined groove, thereby driving the slider 62 to move in the sliding groove of the connecting seat 61. After adjusting the internal thread groove on the surface of the slider 62 to correspond with the thread groove of the flange ring of the external main pipe, the bolt 65 is rotated so that the thread ring of the bolt 65 contacts the outer wall of the tee pipe 4, thereby achieving the effect of initially locking the position of the existing slider 62. Then, the threaded connection is made with the flange ring of the external pipe, thus completing the connection of pipe flanges of different sizes and models.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
