[0002] Fire sprinkler heads are key components of fire hoses, primarily used to control the water flow pattern and spray direction to adapt to the needs of different firefighting scenarios. Common sprinkler heads include direct current sprinkler heads, spray nozzles, and burst nozzles.

However, these carelessly placed nozzles may collide and rub against other structures or each other during the fire truck's movement, leading to wear and tear. Therefore, a fire truck sprinkler head installation mechanism is needed to solve this problem. Utility Model Content

Detailed Implementation
[0039] 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.
[0040] This utility model provides, for example Figure 1-3The fire truck water spray nozzle mounting mechanism shown includes a storage ring 1, a nozzle body 2, and a mounting mechanism 3. The storage ring 1 is fixedly connected to the fire truck. The nozzle body 2 is located in the inner cavity of the storage ring 1. The nozzle body 2 consists of a nozzle main body 21 and two L-shaped fasteners 22. The two L-shaped fasteners 22 are symmetrically fixedly connected to the bottom of the nozzle main body 21. The mounting mechanism 3 is located inside the storage ring 1 and is used to fix the nozzle body 2 inside the storage ring 1.
[0041] The mounting mechanism 3 includes an L-shaped base block 31, multiple extrusion chambers, multiple insertion holes, multiple lifting holes, multiple lifting blocks 32, multiple extrusion plates 33, multiple extrusion springs 34, two limiting grooves, two limiting sliders 35, and an anti-detachment component. The L-shaped base block 31 is fixedly connected to the bottom of the inner wall of the storage ring 1. Multiple extrusion chambers are equidistantly located inside the L-shaped base block 31. Multiple insertion holes are located at the top of the inner wall of the corresponding extrusion chambers. The inner walls of the multiple insertion holes are symmetrically provided with snap-fit grooves, which are slightly larger than the bottom size of the L-shaped snap-fit component 22. Multiple lifting holes are located at the bottom of the inner wall of the corresponding extrusion chambers. The extrusion chambers, insertion holes, and lifting holes at corresponding positions are connected. Block 32 is set in the inner cavity corresponding to the lifting hole. Multiple extrusion plates 33 are rotatably connected to the top of the corresponding lifting block 32. One end of multiple extrusion springs 34 is fixedly connected to the bottom of the corresponding lifting block 32. The other end of multiple extrusion springs 34 is fixedly connected to the bottom of the inner wall of the storage ring 1. The extrusion springs 34 can undergo elastic deformation, thereby driving the lifting block 32 and extrusion plates 33 to automatically perform reset movements. The number of extrusion chamber, insertion hole, lifting hole, lifting block 32, extrusion plate 33 and extrusion springs 34 is the same and the number can be changed according to actual needs. The anti-detachment component is located below the gun head body 21. The anti-detachment component is used to prevent the L-shaped snap fastener 22 from detaching from the extrusion chamber.
[0042] Two limiting grooves are symmetrically opened on the inner wall of the lifting hole, and two limiting sliders 35 are symmetrically fixedly connected to the outer wall of the lifting block 32. The outer walls of the two limiting sliders 35 are slidably sleeved with the inner cavity of the corresponding limiting groove. The limiting grooves and limiting sliders 35 are used to improve the smoothness of the movement of the lifting block 32.
[0043] The anti-detachment component includes multiple first through holes, multiple first anti-detachment rods 36, multiple second through holes, multiple second anti-detachment rods 37, two T-shaped holes, two T-shaped blocks 39, and a force-applying block 310. The multiple first through holes are formed on the inner wall of the corresponding extrusion chamber. The multiple first anti-detachment rods 36 are slidably sleeved within the inner cavity of the corresponding first through holes. The multiple second through holes are formed on the inner wall of the corresponding extrusion chamber. Corresponding first and second through holes are symmetrically formed on the inner wall of the extrusion chamber. The multiple second anti-detachment rods 37 are slidably sleeved within the inner cavity of the corresponding second through holes. The number and size of the first and second anti-detachment rods 36 and 37 are the same. When the first and second anti-detachment rods 36 are located... When the L-shaped locking connector 22 is on both sides, the L-shaped locking connector 22 cannot rotate out of the area between the first anti-detachment rod 36 and the second anti-detachment rod 37. The traction rod 38 is fixedly connected to the front of the multiple first anti-detachment rods 36 and multiple second anti-detachment rods 37. Two T-shaped holes are symmetrically opened on the front of the L-shaped base block 31. Two T-shaped blocks 39 are slidably fitted into the inner cavity of the corresponding T-shaped holes. Both T-shaped blocks 39 are fixedly connected to the back of the traction rod 38. The force application block 310 is fixedly connected to the top of the traction rod 38. The force application block 310 is used to facilitate firefighters to apply force to move the traction rod 38. The outer wall of the force application block 310 is provided with evenly distributed anti-slip textures. The anti-slip textures are used to increase the friction between the force application block 310 and the firefighter's palm.
[0044] Working principle of this utility model:
[0045] When the water nozzle is finished using and needs to be placed in the storage ring 1 of the fire truck, the force block 310 drives the traction rod 38 to move away from the L-shaped bottom block 31. During this process, the first anti-detachment rod 36 and the second anti-detachment rod 37 will gradually detach from the compression chamber. When the traction rod 38 can no longer move, the force applied to the force block 310 is removed. Then, the water nozzle is moved to the top of the insertion hole. After ensuring that the two L-shaped locking pieces 22 are aligned with the two locking slots, force is applied to drive the water nozzle to move vertically downward. During this process, the L-shaped locking pieces 22 will drive the compression plate 33 and the lifting block 32 to move vertically in sync. The downward movement, after the two L-shaped clips 22 are fully inserted into the compression chamber, rotates the water nozzle 90 degrees. After the rotation is completed, the force applied to the water nozzle can be removed. At this time, the compression plate 33 will compress the L-shaped clips 22 under the action of the compression spring 34 to complete the installation step. Finally, the force block 310 drives the traction rod 38, the first anti-detachment rod 36 and the second anti-detachment rod 37 to reset, thus installing the water nozzle in the fire truck's storage ring 1. This effectively prevents the water nozzle from colliding or rubbing against other structures or each other during the movement of the fire truck, improving the protection strength of the water nozzle.
[0046] 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.
