DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] In this embodiment, Figure 1-7 As shown, the present invention provides a portable three-dimensional assembled fire extinguishing device, including a mobile trolley 1 and a multi-stage telescopic tube 2. The multi-stage telescopic tube 2 is located on the upper part of the mobile trolley 1. The number of the mobile trolleys 1 is not less than two, and the multiple mobile trolleys 1 are interconnected. A fixed head 201 is provided on the top of the multi-stage telescopic tube 2. A nozzle 202 is installed on the surface of the fixed head 201. The nozzle 202 is arranged on one side or both sides of the fixed head 201.

[0032] Different pipe structures can be set on the surface of the mobile car 1 to form the front, back, left and right sides of the vehicle. By extending the top multi-stage telescopic tube 2, a fixed head 201 and a nozzle 202 can be installed on the top. According to the different front and back angles of the nozzle 202, such as Figure 1 As shown, when other water pipe channels are connected to the bottom of the multi-stage telescopic tube 2, a water curtain spraying effect can be provided at the front and rear of the vehicle, or a mobile trolley 1 for connecting to a water source can be provided at the bottom of the vehicle to form a spraying effect on the bottom of the vehicle.

[0033] In order to increase the portability of the mobile trolley 1, especially when on-site assembly is required, the multi-stage telescopic tube 2 used is required to have not only a good and reliable storage function, but also to be able to adapt to different water pressures; so there is a Figure 2 The multi-stage telescopic pipe 2 shown in the figure has a specific improved structure including the connection between the multiple pipes and the top structure of the extension pipe 5 on the top;

[0034] In actual use, the situation that easily causes the multi-stage telescopic tube 2 to be unusable is generally that the connection interface part between the water pipes causes the pipe fittings to vibrate and hit the top due to water pressure turbulence; therefore, a sealing assembly 8 is installed between the upper extension tube 5, the middle extension tube 4 and the lower fixed tube 3. Because the inner walls of the middle extension tube 4 and the lower fixed tube 3 are provided with a limiting slide groove 301, the pipe fittings will not rotate when they are extended or retracted, but excessive water pressure will increase the pressure from the inner side of the limiting slide groove 301 to the threaded cover 7; the vertical pressure generated by the extension and retraction of the rod makes the slot 805 at the top of the lap plate 804 correspond to the insert ring 802 at the annular seal 801, so that the raised strip 803 can be inserted into the slot 805. Because the insert ring 802 and the annular seal 801 are connected by screws, a pressure spring is provided between the raised strip 803 and the insert ring 802, so that the pipe fittings can form a mutually embedded buckling effect in multiple directions, and the rubber generated by the extrusion can also form a certain degree of sealing effect;

[0035] In order to form a limiting effect in the vertical direction between the pipe fittings, limiting grooves 401 are provided on the surfaces of the middle extension tube 4 and the upper extension tube 5. When the pipe fittings move, the limiting spring buckle 701 located on the inner side of the bottom of the threaded cover 7 will enter from the inclined surface in the vertical direction of the limiting groove 401, and then the threaded cover 7 that has been partially screwed but not tightened will be tightened a second time, so that the limiting spring buckle 701 generates pressure due to the elastic action and slides in the horizontal groove of the limiting groove 401, so that a vertical limiting effect can be formed between the rods.

[0036] This method not only allows the pipes to be connected based on the lap plates 804 in multiple directions based on the slots 805 and the raised strips 803 and the plug-in rings, but also prevents the pipes from vibrating at different amplitudes due to turbulence; if the lap plate 804 is formed into a ring-shaped structure corresponding to the cross-section of the limiting slide groove 301, the mutual squeezing of the ring-shaped rubber can further form a sealing effect between the pipes.

[0037] In one embodiment, a sealing thread groove is provided between the top of the threaded cover 7 and the middle extension tube 4 or the upper extension tube 5, and the sealing thread groove is provided with a rubber ring for extrusion, so that the threaded cover 7 not only limits it but also connects the upper and lower pipes to each other from the outside.

[0038] In one embodiment, as in the second embodiment, when the sealing degree between the pipes is high, excessive water pressure will not only increase the water pressure of the nozzle 202, but also cause a top-bursting phenomenon at the top of the multi-stage telescopic tube 2; therefore, a device such as the following is provided at the top of the multi-stage telescopic tube 2. Figure 7In the structure shown, that is, at the docking joint 501 on the upper part of the fixed head 201, when the water pressure is too high, the pressure will press the lower connecting seat 903 in the middle of the water blocking disk 905 upward, causing the lower connecting seat 903 to squeeze the telescopic spring 904 upward. The telescopic spring 904 is connected to the upper connecting seat 902 to form a fulcrum that contracts upward, allowing water to flow from between the water blocking disk 905 and the fixed disk 901 to the pressure relief valve 6. The pressure relief valve 6 has two opening methods. One is that the spring one-way valve directly contracts and then discharges water from the drain port 601, thereby allowing the higher water pressure to be released, and the user can adjust the water pressure secondary.

[0039] Another way is when there is a large air pressure or residual water inside, the spring one-way valve can be pulled from the handle to discharge the residual air or residual water inside, making it more convenient to adjust the overall structure.

[0040] In one embodiment, if Figure 8-9 As shown, the mobile trolley 1 is not only provided with an external pipe connection, but also has a built-in pipe connection structure inside. That is, the mobile trolley 1 can connect the external water source to the quick-connect pipe from the middle, and the other trolleys connected at both ends are connected to the corrugated pipe for secondary connection, thus completing the pipe connection function between multiple mobile trolleys 1;

[0041] In order to facilitate storage, a placement layer 102 is further provided at the bottom of the circulation layer 101 for connecting pipes. The retracted multi-stage connecting pipe is mainly stored in the lower mold sleeve 106 inside, and is connected to the inner wall of the placement layer 102 in parallel through a fixed or spring-retractable fixed rod 107. At the same time, the lower mold sleeve 106 falls to the partition plate 103 between the placement layer 102 and the moving layer 104. When fixing, the tail of the retracted multi-stage telescopic rod is mainly placed in the embedded frame 108 at the front end, and the rear end is placed in the mold sleeve groove 109. Then, by twisting the long screw 111, the external connection frame 110 can be extended to the inside of the placement layer 102. The embedded frame 108 is sleeved onto the surface of the docking head 501, and the long screw 111 is screwed and fixed correspondingly to the threaded hole on the inner side of the upper connecting seat 902, so that the front end of the multi-stage connecting pipe can be fixed with a relatively large pressure due to the telescopic spring 904; at the same time, the sponge layer or foam layer provided on the inner wall of the embedded frame 108 is also inserted into the docking head 501 by the long screw 111, so that the embedded frame 108 is sleeved along the lower mold sleeve 106 and connected to the outside of the docking head 501, not only allowing the multi-stage connecting pipe to be protected by the foam layer on the inner wall of the lower mold sleeve 106, but also being fixed in the axial direction, and forming an elastic support member for the entire movable carriage 1 to increase the overall strength;

[0042] An upper mold sleeve 112 is also installed at the bottom of the partition plate 103 between the circulation layer 101 and the placement layer 102, so that the upper mold sleeve 112 and the lower mold sleeve 106 can be spliced together after the upper and lower parts are buckled together. Finally, the circulation layer 101 and the placement layer 102 connected by the hinge can be supported in different directions due to the vertical pressure combined with the axial pressure between the upper mold sleeve 112 and the lower mold sleeve 106, thereby forming a protective effect on the multi-stage connecting pipes.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
