[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] A fire-fighting decontamination passage device with adjustable spray angle, referring to Figures 1-12 As shown, the device includes a quick-release support base 1 to prevent overall shaking and tipping during spray angle adjustment. The upper end of the quick-release support base 1 is snapped with a snap-fit ​​lifting structure 2 for snap-fit ​​limiting and overall lifting of the spray assembly. The upper and lower ends of the snap-fit ​​lifting structure 2 are provided with quick-release assembly 21 to facilitate rapid transfer and deployment of the device. A hand-cranked lifting assembly 22 adapted to people of different heights is fixedly installed between the two quick-release assembly 21. A quick-release head 3 is snapped onto the outside of the quick-release assembly 21 at the upper end of the snap-fit ​​lifting structure 2.

[0020] The quick-release support base 1 prevents the entire unit from shaking and tipping over when adjusting the spray angle. The snap-fit ​​lifting structure 2 achieves the overall lifting and limiting of the spray assembly. The quick-release assembly 21 at the upper and lower ends completes the rapid transfer and deployment of the device. The hand-cranked lifting assembly 22 in the middle is suitable for people of different heights. At the same time, the quick-release head 3 snapped onto the upper quick-release assembly 21 of the snap-fit ​​lifting structure 2 enables the spraying operation.

[0021] Furthermore, the quick-release support base 1 includes a base plate 101. First snap-fit ​​plates 102 are symmetrically fixedly connected to both sides of the base plate 101. First push-pull handle plates 103 are symmetrically fixedly connected to both sides of the upper edge of the base plate 101. A second snap-fit ​​plate 104 is fixedly connected to the middle of the two first push-pull handle plates 103, and slots are provided on the four central pillars of the second snap-fit ​​plate 104. A first fixing plate 105 is fixedly connected to the upper end of the base plate 101 near the first push-pull handle plate 103, and a reserved slot is provided inside the first fixing plate 105. A first connecting post 106 is fixedly connected to one side of the first fixing plate 105, and the first connecting post 106 is hollow and has slots at both ends.

[0022] The quick-release support base 1 bears the overall load with the base plate 101, ensuring stable operation and preventing tipping; the first snap-fit ​​plates 102 on both sides realize the snap-fit ​​limit of components and quick assembly and disassembly; the first push-pull handle plate 103 facilitates handling and transportation; the second snap-fit ​​plate 104 realizes multi-directional stable snap-fit ​​through four-sided slots; the first fixing plate 105 has a reserved slot to neatly store pipelines; the hollow first connecting column 106 with a slot enables quick insertion, while reducing weight and protecting pipelines, achieving the overall effect of stable support, quick assembly and disassembly, and convenient transportation.

[0023] Furthermore, a second connecting post 107 is slidably connected to the slots at both ends of the inner cavity of the first connecting post 106. A return spring 108 is sleeved on the outer side of the second connecting post 107, and the bottom of the return spring 108 is fixedly connected to the side of the second connecting post 107 near the first fixing plate 105. A flipping rod 109 is rotatably connected to the side of the second connecting post 107 away from the first fixing plate 105.

[0024] The second connecting post 107 is slidably installed in the slots at both ends of the inner cavity of the first connecting post 106, and can slide and extend along the slots. One end of the return spring 108, which is sleeved on the outside of the second connecting post 107, is fixed to the side of the second connecting post 107 near the first fixing plate 105. The spring force is used to realize the automatic return of the second connecting post 107 after extension and retraction, ensuring the stability of the structure's rebound. The end of the second connecting post 107 away from the first fixing plate 105 is rotatably connected to the flipping rod 109, so that the flipping rod 109 can rotate. The whole assembly realizes convenient adjustment and disassembly of the components through sliding fit, spring return, and rotational connection. Furthermore, the snap-fit ​​lifting structure 2 includes a quick-release assembly 21, which is snap-fitted into the inner cavity of the second snap-fit ​​plate 104. The quick-release assembly 21 includes a second fixing plate 2101, with a first limiting plate 2102 fixedly connected to the upper end of the second fixing plate 2101. A third snap-fit ​​plate 2103 is slidably connected around the first limiting plate 2102, and a limiting post is provided on the side of the upper end of the multiple third snap-fit ​​plates 2103 near the first limiting plate 2102. A second limiting plate 2104 is rotatably connected to the upper end of the first limiting plate 2102, and the second limiting plate 2104 is connected to the first limiting plate 2102 through a shaft. The inner cavity of the second limiting plate 2104 is symmetrically provided with four positioning slots, and all four positioning slots are snap-fitted with the limiting posts provided on the upper end of the third snap-fit ​​plate 2103.

[0025] The quick-release assembly 21 is snapped into the inside of the second snap-fit ​​plate 104, enabling quick docking and fixing of the snap-fit ​​lifting structure 2 and the quick-release support base 1; the second fixing plate 2101 serves as a basic load-bearing component, providing stable support for the upper components; the first limiting plate 2102 is located on the upper end of the second fixing plate 2101, and the third snap-fit ​​plate 2103 is slidably mounted around its perimeter, allowing the third snap-fit ​​plate 2103 to lock or unlock with the base by its own sliding motion; the limiting post at the upper end of the third snap-fit ​​plate 2103 is used for positioning and limiting, and the first limiting plate 21... 02 The upper end is rotatably connected to the second limiting plate 2104 via a shaft. When the second limiting plate 2104 rotates, the four positioning slots symmetrically opened in its inner cavity engage with the corresponding limiting posts to limit the sliding displacement of the third locking plate 2103 and achieve overall locking. This structure completes the locking and positioning through rotation locking, which is simple and quick to disassemble and assemble. The locking and limiting are firm, effectively preventing the parts from loosening and shaking during lifting operations, improving the structural stability of the sprinkler assembly during lifting and adjustment, and adapting to the use requirements of rapid deployment and disassembly in fire emergency scenarios.

[0026] Furthermore, a driven bevel gear 2105 is fixedly connected to the upper end of the center of the second limiting plate 2104. A driving bevel gear 2106 is meshed with one side of the driven bevel gear 2105. A knob 2107 is fixedly connected to one side of the driving bevel gear 2106. One side of the driving bevel gear 2106 is fixedly connected to the knob 2107 through a connecting rod passing through one side of the second fixing plate 2101.

[0027] Driven bevel gear 2105 is fixed to the upper center of the second limiting plate 2104 and meshes with the driving bevel gear 2106. One side of the driving bevel gear 2106 passes through the second fixed plate 2101 via a connecting rod, and the end of the connecting rod is fixedly connected to the knob 2107. When the operator rotates the knob 2107, the knob 2107 drives the driving bevel gear 2106 fixed thereto to rotate synchronously. Since the driving bevel gear 2106 and the driven bevel gear 2105 mesh with each other, the rotational power of the driving bevel gear 2106 will be transmitted to the driven bevel gear 2105, thereby driving the driven bevel gear 2105 and the second limiting plate 2104 fixed thereto to rotate synchronously, ultimately realizing the angle or position adjustment of the second limiting plate 2104.

[0028] Furthermore, a hand-cranked lifting assembly 22 is fixedly connected to the middle of the quick-release assembly 21. The hand-cranked lifting assembly 22 includes a third fixing plate 2201. One side of the third fixing plate 2201 is fixedly connected to the upper surface of the second fixing plate 2101. Guide rails 2202 are symmetrically fixedly connected to both sides of the third fixing plate 2201. A fourth fixing plate 2203 is fixedly connected to one side of the inner wall of the third fixing plate 2201. A threaded sleeve 2204 is fixedly connected to one side of the fourth fixing plate 2203 away from the third fixing plate 2201. A driven gear 2205 is fixedly connected to the upper end of the threaded sleeve 2204, and the threaded sleeve 2204 and the driven gear 2205 are connected by a shaft.

[0029] The third fixing plate 2201 is fixed on one side of the upper surface of the second fixing plate 2101, and guide rails 2202 are symmetrically fixed on both sides of it. The fourth fixing plate 2203 is fixed on one side of the inner wall. The threaded sleeve 2204 is fixed on the side of the fourth fixing plate 2203 away from the third fixing plate 2201. The upper end of the threaded sleeve 2204 is fixedly connected to the driven gear 2205 through the shaft. When the driven gear 2205 is driven to rotate by external force, the driven gear 2205 drives the threaded sleeve 2204 to rotate synchronously through the shaft. The threaded sleeve 2204 and the matching screw form a threaded engagement, and the rotational motion is converted into linear lifting motion. At the same time, the guide rails 2202 on both sides of the third fixing plate 2201 play a guiding and limiting role for the lifting action, ensuring that the lifting process is stable and does not deviate, and finally realizes the smooth lifting and adjustment of the entire hand-cranked lifting assembly 22 and the associated quick-release assembly 21.

[0030] Furthermore, a folding handle 2206 is provided on one side of the third fixing plate 2201. A first transmission screw 2207 is fixedly connected to one side of the folding handle 2206. One side of the first transmission screw 2207 passes through one side of the third fixing plate 2201 and is fixedly connected to the folding handle 2206. One side of the first transmission screw 2207 is meshed with the driven gear 2205.

[0031] A folding handle 2206 is located on one side of the third fixed plate 2201, and one side of it is fixedly connected to the first transmission screw 2207. The first transmission screw 2207 passes through one side of the third fixed plate 2201 and is firmly fixed to the folding handle 2206. At the same time, one side of the first transmission screw 2207 is meshed with the driven gear 2205 in the hand-cranked lifting assembly 22. When the operator unfolds the folding handle 2206 and rotates it manually, the folding handle 2206 drives the first transmission screw 2207 fixed to it to rotate synchronously. Since the first transmission screw 2207 and the driven gear 2205 are meshed with each other, its rotational power is accurately transmitted to the driven gear 2205, thereby driving the driven gear 2205 to rotate, providing power for the subsequent rotation of the threaded sleeve 2204 and the lifting of the assembly, and finally realizing the lifting and adjustment of the hand-cranked lifting assembly 22 and the quick-release assembly 21. When not in use, the folding handle 2206 can be folded to reduce space occupation.

[0032] Furthermore, a fifth fixed plate 2208 is slidably connected to the guide rail 2202 on the outer side of the fourth fixed plate 2203. A second transmission screw 2209 is fixedly connected to the lower end of the fifth fixed plate 2208, and the second transmission screw 2209 is assembled inside the threaded sleeve 2204. A guide groove 2210 is provided on one side of the fifth fixed plate 2208, and the guide groove 2210 is engaged with the side of the folding handle 2206 near the fourth fixed plate 2203.

[0033] The fifth fixing plate 2208 is slidably connected to the guide rail 2202 on the outside of the fourth fixing plate 2203, and can slide up and down along the guide rail 2202; the second transmission screw 2209 fixedly connected to its lower end is assembled inside the original threaded sleeve 2204, forming a threaded engagement with the threaded sleeve 2204; at the same time, the guide groove 2210 opened on one side of the fifth fixing plate 2208 is engaged with the side of the folding handle 2206 near the fourth fixing plate 2203, realizing the limiting of the folding handle 2206. When the folding handle 2206 drives the first transmission screw 2207 and the driven gear 220... When the threaded sleeve 2204 rotates, the threaded sleeve 2204 and the internally assembled second transmission screw 2209 undergo threaded transmission, converting the rotational motion into linear motion, which drives the fifth fixed plate 2208 to slide up and down along the guide rail 2202. During this process, the guide rail 2202 provides lifting guidance for the fifth fixed plate 2208, and the guide groove 2210 limits the folding handle 2206 to prevent it from deviating when rotating, ensuring that the entire transmission and lifting action is smooth and precise, and ultimately driving the components associated with the fifth fixed plate 2208 to achieve synchronous lifting.

[0034] Furthermore, a storage plate 23 is fixedly connected to the inner cavity of the quick-release assembly 21 at the upper end. A fourth snap-fit ​​plate 24 is symmetrically fixedly connected to the lower side of one side of the second fixing plate 2101. When stored, the fourth snap-fit ​​plate 24 snaps into the first fixing plate 105 and is fixedly snapped in place by a self-locking assembly on one side. A cover plate 26 is snapped into the upper end of the storage plate 23. A sixth fixing plate 25 is slidably connected to the lower side of the cover plate 26. The sixth fixing plate 25 is fixedly connected to the lower side of one side of the second fixing plate 2101. A third limiting plate 27 is fixedly connected to the center of the upper end of the cover plate 26.

[0035] The storage plate 23 is fixed to the inner cavity of the upper quick-release assembly 21 for storing related components. A fourth snap-fit ​​plate 24 is symmetrically fixed to the lower side of the second fixing plate 2101. When the components are stored, the fourth snap-fit ​​plate 24 will snap onto the first fixing plate 105 and be fixed by a self-locking component on one side to achieve a stable lock in the stored state. A cover plate 26 is snapped onto the upper end of the storage plate 23 for protecting the components inside the storage plate 23. The lower side of the cover plate 26 is slidably connected to the sixth fixing plate 25, which is fixed to the lower side of the second fixing plate 2101, so that the cover plate 26 can slide smoothly along the sixth fixing plate 25, facilitating the opening and closing of the cover plate 26. A third limiting plate 27 is fixed at the center of the upper end of the cover plate 26 for limiting the cover plate 26 or related components to prevent the cover plate 26 from sliding excessively or shifting, ensuring the stable operation of the entire storage and protection structure.

[0036] Furthermore, the quick-release head 3 includes a fifth snap-fit ​​plate 301, and the central column of the inner wall of the fifth snap-fit ​​plate 301 is provided with a snap-fit ​​groove. The inner cavity of the fifth snap-fit ​​plate 301 is snapped into the quick-release assembly 21 at the upper position. The two ends of the fifth snap-fit ​​plate 301 are symmetrically fixedly connected with second push-pull handle plates 302. The upper end of the second push-pull handle plates 302 and the fifth snap-fit ​​plate 301 are fixedly connected with a seventh fixing plate 303.

A water pipe fixing plate 304 is symmetrically fixedly connected to one side of the upper end of the seventh fixing plate 303 near the edge.

[0037] The quick-release head 3 includes a fifth clamping plate 301, and clamping grooves are provided at the central columns of the inner walls around its periphery for assisting in clamping and positioning. The inner cavity of the fifth clamping plate 301 is in clamping fit with the upper quick-disassembly and assembly component 21, realizing the quick assembly and disassembly of the quick-release head 3 and the overall mechanical structure. Second push and pull hand plates 302 are symmetrically fixed at both ends of the fifth clamping plate 301, facilitating the operator to hold and exert force to assist in completing the disassembly and assembly actions of the spray head 309.
