Description

Technical Field

[0001] This invention relates to the field of fire protection, specifically to a multi-angle adjustable positioning device for fire truck fire monitors. Background Technology

[0002] Water spraying devices are commonly used in fields such as garden irrigation, road dust suppression, fire fighting, and industrial sprinkler systems. Traditional fixed water spraying devices are mostly simple in structure, with fixed spray direction and angle, which cannot be flexibly adjusted according to actual working conditions, operating range, and environmental conditions. This limits their use and makes it difficult to meet the diverse and large-scale water spraying needs.

[0003] To achieve angle adjustment, existing adjustable water spray devices often employ simple hinged or multi-section pipe splicing structures, which have the following drawbacks: First, the adjustment process is cumbersome, requiring tools to disassemble or loosen multiple fasteners, resulting in low adjustment efficiency and inconvenience. Second, the positioning stability after adjustment is poor, and angle deviation or loosening is prone to occur under water pressure impact or external force, affecting the water spray accuracy and operational effect. Third, the vertical pitch angle and horizontal rotation angle are difficult to adjust flexibly and synchronously, resulting in an unreasonable overall structural layout and limited reliability and service life.

[0004] Therefore, it is essential to provide a multi-angle adjustable positioning device for fire truck fire monitors to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a multi-angle adjustment and positioning device for fire truck fire monitors.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a multi-angle adjustment and positioning device for fire truck fire monitors, including a horizontal base and a horizontal rotating seat rotatably connected to the horizontal base, a vertical seat connected to the horizontal rotating seat, a rotating water pipe rotatably connected to the vertical seat, and a water spray gun connected to the rotating water pipe. The horizontal rotating seat is used to drive the water spray gun to rotate in the horizontal direction; the rotating water pipe is used to drive the water spray gun to rotate in the vertical direction.

[0007] Furthermore, the vertical seat is C-shaped, and the rotating water pipe is rotatably connected to the C-shaped vertical seat.

[0012] Furthermore, the screw is connected to an abutment, and the vertical seat is connected to a rotating water pipe fixing part. The rotating water pipe fixing part is provided with anti-slip texture, and the abutment abuts against the rotating water pipe fixing part.

[0013] Furthermore, a rotating handle is connected to the end of the screw away from the abutment.

[0014] Furthermore, the rotating handle is made of rubber.

[0015] Furthermore, a brake grinding block is connected to the horizontal base, a brake rope is connected to the brake grinding block, and a brake pad is connected to the horizontal rotating seat. The brake grinding block is used to abut against the brake pad in the braking position. A locking connector is connected to one end of the brake rope near the handrail frame, and a locking seat is connected to the handrail frame. The locking connector engages with the locking seat.

[0019] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0021] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "over," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation.

Therefore, the exemplary terms "below" and "under" can include both upper and lower orientations. Furthermore, the device may also include other orientations, such as being rotated 90 degrees or other orientations, and the spatial descriptive terms used herein will be interpreted accordingly.

[0022] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0023] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0024] like Figures 1 to 8 As shown, the fire truck's fire monitor multi-angle adjustable positioning device includes a horizontal base 100 made of one-piece stainless steel with an anti-slip pad on the bottom to ensure the stability of the entire device during placement and prevent slippage due to water pressure impact during operation. The horizontal swivel base 200 is rotatably connected to the top center of the horizontal base 100 via a thrust bearing. The thrust bearing reduces friction during rotation, making horizontal rotation smoother and ensuring coaxiality during rotation to prevent misalignment.

[0025] The top of the horizontal rotating base 200 is fixedly connected to the vertical base 300 by welding. The connection between the two is firm and can bear the weight of the water gun 500 and the rotating water pipe 400, while resisting the reaction force during water spraying. The vertical base 300 is C-shaped, with its opening facing one side. The C-shaped structure facilitates the installation and rotation of the rotating water pipe 400, while providing sufficient rotation space for the rotating water pipe 400 to avoid interference.

[0026] The rotating water pipe 400 has a frame structure with symmetrical rotating rings 600 welded on both sides. The rotating rings 600 are made of wear-resistant alloy steel, and their inner diameter is matched with the outer diameter of both ends of the vertical seat 300. The rotating water pipe 400 achieves a rotating connection with the vertical seat 300 through the cooperation of the rotating rings 600 and the rotating part 610. Lubricating oil can be applied between the rotating rings 600 and the vertical seat 300 to further reduce rotational resistance and extend service life.

[0027] The front end of the rotating water pipe 400 is fixedly connected to the water gun 500 by bolts. The water inlet of the water gun 500 can be connected to the water source through a hose. When the rotating water pipe 400 rotates around the vertical seat 300, it can drive the water gun 500 to pitch and rotate in the vertical direction. When the horizontal rotating seat 200 rotates around the horizontal base 100, it can drive the entire vertical seat 300, the rotating water pipe 400 and the water gun 500 to rotate in the horizontal direction, thereby realizing the multi-angle adjustment of the water gun 500 in both the horizontal and vertical directions.

[0028] The rear end of the rotating water pipe 400 is welded with a handrail 700. The handrail 700 is U-shaped and its height is adapted to the comfortable height of the human body when operating. The operator can easily push the rotating water pipe 400 to adjust the vertical angle by holding the handrail 700. At the same time, the operator can also push the handrail 700 to drive the horizontal rotating seat 200 to adjust the horizontal rotation. The operation is labor-saving and convenient.

[0029] A vertical limiting member 800 is welded to one side of the handrail frame 700. The vertical limiting member 800 is used to fix the water pipe 400 after it has been adjusted to the required angle, so as to prevent angle deviation due to water pressure impact or external force. Specifically, the vertical limiting member 800 includes a nut frame 810, a nut 820, a screw 830, abutment 840, and a rotating handle 850. The nut frame 810 is welded to the handrail frame 700, the nut 820 is fixedly connected to the middle of the nut frame 810 by bolts, the screw 830 is threaded to the nut 820, and one end of the screw 830 passes through the nut frame 810 and is rotatably connected to the handrail frame 700, while the other end of the screw 830 extends to the outside of the handrail frame 700.

[0030] One end of the screw 830 near the vertical seat 300 is threadedly connected to an abutment 840. The abutment 840 is made of rubber, possessing elasticity and friction to prevent wear on the vertical seat 300 during contact. Correspondingly, a rotating water pipe fixing part 310 is welded to the outer wall of the vertical seat 300. The outer circumferential surface of the rotating water pipe fixing part 310 is provided with anti-slip textures 320, which are evenly distributed in a ring to increase the friction between the abutment 840 and the rotating water pipe fixing part 310, improving the locking effect. When it is necessary to fix the angle of the rotating water pipe 400, the screw 830 is rotated to make the abutment 840 and the rotating water pipe fixing part 310 fit tightly together, and the rotating water pipe 400 is locked and fixed by friction. When it is necessary to adjust the angle, the screw 830 is rotated in the opposite direction to separate the abutment 840 from the rotating water pipe fixing part 310, and the handrail frame 700 can be pushed to adjust the angle.

[0031] A rotating handle 850 is welded to the end of the screw 830 away from the abutment 840. The rotating handle 850 is cylindrical and made of rubber. The rubber material improves the operator's grip comfort and increases the grip friction, making it easier to rotate the screw 830. The outer circumferential surface of the rotating handle 850 may be provided with anti-slip protrusions to further enhance the ease of operation.

[0032] A brake grinding block 110 is connected to the horizontal base 100, and a brake rope 130 is connected to the brake grinding block 110. A brake pad 120 is connected to the horizontal rotating base 200. The brake grinding block 110 is used to abut against the brake pad 120 in the braking position. A locking connector 140 is connected to one end of the brake rope 130 near the handrail 700. A locking seat 710 is connected to the handrail 700, and the locking connector 140 is locked into the locking seat 710. By pulling the brake rope 130, the brake grinding block 110 abuts against the brake pad 120, thereby performing the braking operation.

[0033] In use, first place the horizontal base 100 on a flat surface, ensuring stability with the anti-slip pad at the bottom. Connect the water inlet of the water gun 500 to the water source via a hose, turn on the water, and the water gun 500 will begin spraying water. The operator holds the handrail 700 and pushes the horizontal rotating seat 200 to rotate around the horizontal base 100, adjusting the horizontal spray angle of the water gun 500. After adjusting to the desired angle, insert the locking connector 140 on the brake rope 120 into the locking seat 710 on the handrail 700 to fix the horizontal angle. Then, push the handrail 700 to rotate the rotating water pipe 400 around the vertical seat 300, adjusting the vertical spray angle of the water gun 500. After adjustment, rotate the rotating handle 850 so that the screw 830 drives the abutment 840 to tightly abut against the rotating water pipe fixing part 310 on the vertical seat 300, locking the vertical angle. When the angle needs to be adjusted, simply reverse the operation. The entire adjustment process is simple, quick, and the positioning is stable and reliable.

[0034] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The water gun can be adjusted at multiple angles in both the horizontal and vertical directions by the cooperation of the horizontal rotating seat and the vertical rotating frame; the vertical angle can be quickly locked and fixed by the vertical limiting component, and the structure is stable and reliable; the handrail frame facilitates manual adjustment and operation, and the horizontal limiting rope can limit the horizontal rotation range and achieve quick positioning. The overall structure is simple, easy to adjust, and highly practical.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
