Description

Technical Field

[0001] This utility model relates to the field of mobile water cannons, and in particular to a portable mobile water cannon frame. Background Technology

[0002] Water cannons are commonly used in many fields such as fire fighting and industrial cleaning. They are used to spray water to achieve purposes such as fire extinguishing and cleaning. In order to facilitate the movement and use of water cannons, they usually need to be equipped with special mobile frames. The existing water cannon mobile frames have relatively simple structures and generally only have basic load-bearing and movement functions, which have many shortcomings in terms of functionality and ease of use.

[0003] Currently, water cannon mobile racks on the market are usually fixed as a single unit and cannot be folded for storage. As a result, when not in use, the mobile rack occupies a lot of space, causing inconvenience for storage and transportation. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a portable water cannon frame, which aims to improve the problem that "most water cannon frames are fixed structures and cannot be folded and stored" in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a portable mobile water cannon frame, comprising a frame plate and two sets of folding plates hinged to the front and rear sides of the frame plate. Two sets of universal wheels are symmetrically fixedly installed at the bottom ends of each of the two sets of folding plates. A push handle is fixedly connected to the left side of the frame plate. Folding mechanisms are provided on both the front and rear sides of the frame plate. Support components are fixedly connected to both the left and right sides of the frame plate. The folding mechanism includes a guide component and a locking component. The guide component includes a bidirectional screw, a limiting frame, two sets of guide blocks, and a limiting groove. A bidirectional screw runs through the left and right sides and is rotatably connected to the middle of the frame plate. The frame plate has a second sliding groove near the middle of the left and right sides. The front and rear sides of the two sets of second sliding grooves have first sliding grooves. The guide block is slidably connected to the inner wall of the second sliding groove. The limiting frame slides on the inner wall of the first sliding groove. The front and rear sides of the guide block have two sets of guide grooves symmetrically opened. The limiting frame is inserted into the inner wall of the limiting groove. The two sets of guide blocks are symmetrically threaded to the threads on the outer wall of the bidirectional screw near the left and right sides. The locking assembly includes a protrusion, a positioning hole, a slot, and a positioning rod.

[0006] As a further description of the above technical solution: The positioning rod is fixedly connected to the upper part of the limit frame away from the opening. The slot is opened at the top of the frame plate near the right side. The positioning rod slides through the slide groove into the inside of the slot.

[0007] As a further description of the above technical solution: The support assembly includes two sets of fixing blocks symmetrically and fixedly connected on the left and right sides of the frame plate. Each of the fixing blocks has a threaded rod threaded through and threadedly connected to its center. Each of the threaded rods has a disc rotatably connected to its bottom end. Each of the discs has a rubber disc fixedly connected to its bottom end. Each of the threaded rods has a knob fixedly connected to its top end.

[0008] As a further description of the above technical solution: The limiting frame is U-shaped and faces outwards. The side of the limiting frame away from the opening is round. The side of the limiting frame away from the opening is slidably connected to the inner wall of the guide groove.

[0009] As a further description of the above technical solution: Both sets of guide grooves are designed to be arc-shaped.

[0010] As a further description of the above technical solution: Both ends of the bidirectional screw are fixedly connected to turntables.

[0011] As a further description of the above technical solution: The positioning rod is inserted into the inner wall of the positioning hole, and the protrusion is fixedly connected to the top of the folding plate near the right side and opposite to the slot. The protrusion is inserted into the inner wall of the slot.

[0012] As a further description of the above technical solution: The positioning hole is located on one side near the frame plate, and the front side of the protrusion is set as a slope.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the foldable design of the folding plate allows for easy folding, effectively reducing the occupied area and facilitating storage and transportation. This solves the problem of existing water cannon mobile frames being unable to be folded, resulting in large space occupation. Furthermore, when unfolded, the water cannon can be stably supported and moved in conjunction with the stable limiting frame.

[0014] 2. In this utility model, mounting holes are opened at the top of the frame plate of the movable frame, and bolts can be used to achieve a detachable and fixed connection between the water cannon and the frame plate, which can adapt to the installation requirements of water cannons of different specifications, facilitate later maintenance and disassembly, and at the same time, the support components are set to increase the stability of the frame plate, which can balance the pressure of the water cannon impact and ensure the stability of the water cannon during operation.

Detailed Implementation

[0017] 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.

[0018] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a portable mobile water cannon frame, comprising a frame plate 1 and two sets of folding plates 22 hinged to the front and rear sides of the frame plate 1. Two sets of casters are symmetrically fixed to the bottom ends of each set of folding plates 22. The frame plate 1 serves as the core load-bearing base of the entire mobile frame, providing a stable installation reference and structural support for the water cannon installation, folding mechanism 2, and support components 3. The top of the frame plate 1 has mounting holes for use with bolts to achieve a detachable and fixed connection between the water cannon and the frame plate 1, ensuring that the water cannon will not shift during use and facilitating later maintenance and disassembly. It adapts to the installation requirements of water cannons of different specifications. A drive mechanism for the frame plate 1 is fixedly connected to the left side of the frame plate 1. The movable push handle and the frame plate 1 are equipped with folding mechanisms 2 on both the front and rear sides to fold the folding plates 22 on both sides of the frame plate 1, thereby reducing the area occupied. The left and right sides of the frame plate 1 are fixedly connected with support components 3 to increase the stability of the frame plate 1 and balance the pressure of the water cannon impact. The folding mechanism 2 includes a guide component and a locking component. The guide component includes a bidirectional screw 28, a limit frame 24, two sets of guide blocks 210 and a limit groove 23. The bidirectional screw 28 passes through the left and right sides and is rotatably connected to the middle of the frame plate 1. The frame plate 1 supports the bidirectional screw 28. The frame plate 1 is provided with a second sliding groove 27 near the middle of the left and right sides. The second sliding groove 27 provides space for the guide blocks 210 to slide.

[0019] Furthermore, both sides of the two sets of slide grooves 27 are provided with slide grooves 26. Slide grooves 26 provide space for the movement of the limiting frame 24. Guide blocks 210 are slidably connected to the inner wall of slide grooves 27. The two sets of guide blocks 210 convert the rotational motion of the bidirectional screw 28 into its own linear motion, and then drive the limiting frame 24 to move through the guide groove 211. The limiting frame 24 slides on the inner wall of slide groove 26. The limiting frame 24 is U-shaped and faces outward. Its U-shaped end away from the opening can slide on the inner wall of the guide groove 211. The guide blocks 210 move left and right, driving the guide groove 211 to move. The guide groove 211 drives the limiting frame 24 to move back and forth. The side of the limiting frame 24 away from the opening is a round rod shape. Two sets of guide grooves 211 are symmetrically provided on the front and rear sides of the guide block 210. Both sets of guide grooves 211 are arc-shaped. The arc shape can smoothly convert the left and right linear movement of the guide block 210 into the front and back linear movement of the limit frame 24. The side of the limit frame 24 away from the opening is slidably connected to the inner wall of the guide groove 211. The limit frame 24 is inserted into the inner wall of the limit groove 23. The mechanical locking of the folding plate 22 after it is unfolded is achieved through the insertion and engagement, preventing the limit frame 24 from loosening and causing the folding plate 22 to shift during use. The two sets of guide blocks 210 are symmetrically threaded to the threads on the outer wall of the bidirectional screw 28 near the left and right sides. Turntables 25 are fixedly connected to both ends of the bidirectional screw 28 to facilitate the rotation of the bidirectional screw 28.

[0020] Reference Figure 1 , Figure 3 and Figure 4 The locking assembly includes a protrusion 21, a positioning hole 212, a slot 29, and a positioning rod 213. The protrusion 21, by inserting into the slot 29 and cooperating with the positioning rod 213, positions the folded plate 22 after folding. The positioning rod 213 is fixedly connected to the upper part of the limit frame 24 away from the opening. The positioning rod 213 is inserted into the positioning hole 212 through a through-slide groove 26, firmly fixing the protrusion 21 to the frame plate 1 and ensuring the locking effect of the folded plate 22. The slot 29 is located at the top of the frame plate 1 near the right side. The positioning rod 213 slides through the through-slide groove 26 into the inside of the slot 29. The positioning rod 213 is inserted into the inner wall of the positioning hole 212, and the positioning hole 212 and the positioning rod 213 are precisely matched. The protrusion 21 is rigidly locked to the frame plate 1 by plugging, thereby fixing the position of the folding plate 22. The protrusion 21 is fixedly connected to the top of the folding plate 22 near the right side and is set opposite to the slot 29. The slot 29 provides a space for the protrusion 21 and the positioning rod 213 to achieve precise docking and also to position and lock. The protrusion 21 is plugged into the inner wall of the slot 29. After the folding plate 22 is folded, the protrusion 21 can be inserted into the slot 29. The positioning rod 213 will limit the position of the protrusion 21 and the folding plate 22. The positioning hole 212 is opened on the side near the frame plate 1. The front side of the protrusion 21 is set as a slope. By setting it as a slope, it can prevent the two sets of folding plates 22 from being blocked when folding.

[0021] Reference Figure 1 and Figure 2 The support component 3 includes two sets of fixing blocks 31 symmetrically and fixedly connected on the left and right sides of the frame plate 1. The fixing blocks 31 provide support. The middle of each of the fixing blocks 31 is threaded and connected to a threaded rod 34 that drives the disc 33 to move up and down. The bottom of each of the threaded rods 34 is rotatably connected to a disc 33 that supports a rubber disc 32. The bottom of each of the discs 33 is fixedly connected to a rubber disc 32 made of rubber to increase friction with the ground and improve stability. The top of each of the threaded rods 34 is fixedly connected to a knob that facilitates the rotation of the threaded rods 34.

[0022] Working principle: When in use, unfold the two sets of folding plates 22 to the front and rear sides of the frame plate 1. Rotate the turntable 25 to drive the bidirectional screw 28 to rotate. Since the two sets of guide blocks 210 are symmetrically threaded on the bidirectional screw 28, and the left and right sections of the bidirectional screw 28 have opposite screw directions, the guide blocks 210 will move relatively close in a straight line along the slide groove 27. The arc-shaped guide grooves 211 on the front and rear sides of the guide blocks 210 will drive the limit frame 24 to move outward along the slide groove 26 until the limit frame 24 is inserted into the limit groove 23 on the folding plate 22, completing the locking of the unfolded folding plate 22. Then, rotate the knob in the support assembly 3 to drive the threaded rod 34 to rotate, so that the rubber disc 32 at the bottom of the disc 33 is in close contact with the ground. Fix the water cannon to the frame plate 1 through the mounting holes and bolts. The mobile frame can then be moved to the working position for use by pushing the handle and the casters. When folding and storing, the turntable 25 is rotated in the opposite direction. The bidirectional screw 28 drives the two sets of guide blocks 210 to move relatively away from each other along the slide groove 27. The guide groove 211 drives the limiting frame 24 to move inward along the slide groove 26. The limiting frame 24 disengages from the limiting groove 23, folding the folding plate 22 towards the frame plate 1, so that the protrusion 21 on the folding plate 22 is inserted into the slot 29. At this time, the bidirectional screw 28 is rotated to drive the limiting frame 24 to move the positioning rod 213 into the slot 29. The positioning rod 213 passes through the slide groove 26 and is inserted into the positioning hole 212 of the protrusion 21, completing the folding and locking of the folding plate 22. At this time, the overall volume of the mobile frame is reduced, making it easier to store and transport.

[0023] 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.
