Description

Technical Field

[0001] This utility model relates to the field of processing all-plastic anti-theft nozzles, and in particular to an all-plastic anti-theft nozzle. Background Technology

[0002] Anti-theft sprinklers, used as tools for water resource management and equipment protection, are typically placed in open or semi-open areas such as public green spaces, residential gardens, roadside green belts, and golf courses. The all-plastic sprinkler head, made of a chemically stable material, is resistant to corrosion from various chemicals, such as alcohol, oil stain remover, and disinfectant. It is not easily corroded. By mechanically pressing, the pressure, flow rate, or shape of the internal fluid channel is changed. The anti-theft function makes the sprinkler head more practical and gives the product a more high-end and special feel.

[0003] However, the existing all-plastic anti-theft sprinkler head still has some problems in actual use: when using the sprayer to spray public green spaces, road green belts and other areas, the user's wrist needs to lift the sprayer up and down repeatedly to change the spray angle of the nozzle, which requires excessive force from the wrist and forearm muscles. This sudden and high-intensity force will cause the muscles and ligaments to fatigue quickly, resulting in soreness and pain, which is not good for the health of the arm and is not humane. Utility Model Content

[0004] This invention provides an all-plastic anti-theft nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A burglarproof all-plastic nozzle includes a nozzle housing and a nozzle, wherein the surface of the nozzle is provided with a convenient spray angle adjustment mechanism; The convenient spray angle adjustment mechanism includes a flow guide tube, one end of which is sleeved on the surface of the nozzle. A fixing block is fixedly connected to one end of the surface of the flow guide tube. Both sides of the fixing block are rotatably connected to connecting rods via rotating shafts. A lever is fixedly connected to one end of one side of the connecting rod. A limit support rod is slidably connected to one end of the connecting rod. One end of the limit support rod is fixed to one side of the top of the nozzle housing.

[0006] As a further improvement to this technical solution: one end of the nozzle is inserted into the top of one side of the nozzle housing through a through hole, and a pressing handle is rotatably connected to one side of the lower end of the nozzle housing through a rotating shaft.

[0007] As a further improvement to this technical solution: a plastic block is slidably connected to the middle of one side of the nozzle housing through a through hole, and a pressure valve adjustment mechanism is fixedly connected to one end of the plastic block.

[0008] As a further improvement to this technical solution: the pressure valve adjusting mechanism includes a fixed block two, the top of the fixed block two is rotatably connected to an auxiliary connecting rod via a rotating shaft, one end of the auxiliary connecting rod is rotatably connected to a movable block via a rotating shaft, and one end of the movable block is fixedly connected to the other end of the plastic block.

[0009] As a further improvement to this technical solution: a piston mechanism is fixedly connected to the lower end of the second fixing block, and a connecting plug is inserted into the lower end of the piston mechanism.

[0010] As a further improvement to this technical solution: the piston mechanism includes a piston housing, a plastic spring is fixedly connected to the inner bottom wall of the piston housing, a pressure block is fixedly connected to the upper end of the plastic spring, and a protective shell is fixedly connected to the surface of the piston housing.

[0011] As a further improvement to this technical solution: the bottom end of the inner wall of the connecting plug is provided with anti-theft teeth, which are distributed in a ring array around the center of the connecting plug.

[0012] As a further improvement to this technical solution: anti-slip protrusions are fixedly connected to one side of both the front and back of the nozzle housing, and the anti-slip protrusions are made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The convenient adjustment mechanism for nozzles and spray angle allows the user to easily adjust the spray angle by moving the lever, which in turn moves the fixed block along with the connecting rod. This changes the spray angle of the drainage tube outlet, allowing the user to adjust the spray angle without repeatedly lifting and lowering the nozzle. This avoids the user having to exert excessive force to control the sprayer, thus preventing arm soreness and pain, making it more user-friendly.

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0018] Please see Figures 1-3 In this embodiment of the utility model, an all-plastic anti-theft nozzle includes a nozzle housing 1 and a nozzle 2. The surface of the nozzle 2 is provided with a convenient spray angle adjustment mechanism 3. The spray angle adjustment mechanism 3 includes a flow guide tube 301. One end of the flow guide tube 301 is sleeved on the surface of the nozzle 2. A fixing block 302 is fixedly connected to one end of the surface of the flow guide tube 301. Both sides of the fixing block 302 are rotatably connected to a connecting support rod 303 via a rotating shaft. A lever 304 is fixedly connected to one end of one side of the connecting support rod 303. A limit support rod 305 is slidably connected to one end of the connecting support rod 303. One end of the limit support rod 305 is fixed to one side of the top of the nozzle housing 1.

[0019] The lever 304 is designed in a semi-circular shape, which makes it easy for the user's thumb to grip the lever 304. When using the spray bottle, the spray angle of the drainage tube 301 can be controlled with one hand, which provides convenience for use. The limiting support rod 305 is set in a horizontal direction. The surface aperture of the limiting support rod 305 matches the aperture of one end of the connecting support rod 303. A circular protrusion is provided at one end of the limiting support rod 305 to limit the range of sliding of the connecting support rod 303 on the surface of the limiting support rod 305 and prevent it from leaving the sliding range.

[0020] Please see Figures 1-2 One end of the nozzle 2 is inserted into the top of one side of the nozzle housing 1 through a through hole, and a pressing handle 4 is rotatably connected to one side of the lower end of the nozzle housing 1 through a rotating shaft.

[0021] The nozzle 2 can be detachably installed in the corresponding insertion hole position of the nozzle housing 1. The nozzle 2 is equipped with a circular nozzle hole and a multi-hole or narrow slit nozzle hole for different functions. After pressing the handle 4, the circular nozzle hole can spray out a columnar liquid flow, while the multi-hole or narrow slit nozzle hole can spray out a spray or foam.

[0022] Please see Figures 1-2 4. A plastic block 5 is slidably connected to the middle of one side of the nozzle housing 1 through a through hole, and a pressure valve adjustment mechanism 6 is fixedly connected to one end of the plastic block 5.

[0023] Press the handle 4, and the back of the handle 4 presses against one end of the plastic block 5. The plastic block 5 serves as the intermediate part between the pressure valve adjustment mechanism 6 and the handle 4, and guides the pressing direction of the pressure valve adjustment mechanism 6.

[0024] Please see Figure 4 The pressure valve adjusting mechanism 6 includes a fixed block 601. The top of the fixed block 601 is rotatably connected to an auxiliary connecting rod 602 via a rotating shaft. One end of the auxiliary connecting rod 602 is rotatably connected to a movable block 603 via a rotating shaft. One end of the movable block 603 is fixedly connected to the other end of the plastic block 5.

[0025] The fixed block 601, auxiliary connecting rod 602, and movable block 603 cooperate with each other. When the plastic block 5 is pressed inward by the handle 4, the movable block 603 moves backward, and the auxiliary connecting rod 602 and the fixed block 601 make adaptive bending cooperation to ensure that the fixed block 601 can always keep vertically aligned with the piston mechanism 7, so as to avoid affecting the cooperation between the piston mechanism 7 and the plastic block 5.

[0026] Please see Figures 1-2 A piston mechanism 7 is fixedly connected to the lower end of the fixed block 601, and a connecting plug 8 is inserted into the lower end of the piston mechanism 7.

[0027] The surface of the connecting plug 8 is provided with rectangular concave surfaces distributed in a ring. The ring distribution of the rectangular concave surfaces ensures uniform, multi-point contact throughout the entire circumference of the plug, rather than relying on only a few points on the outer wall. The significant increase in the contact area with the hand prevents slippage when installing the nozzle on the spray bottle, thus avoiding difficulties in disassembly and installation.

[0028] Please see Figure 4 The piston mechanism 7 includes a piston housing 701, a plastic spring 702 is fixedly connected to the inner bottom wall of the piston housing 701, a pressure block 703 is fixedly connected to the upper end of the plastic spring 702, and a protective housing 9 is fixedly connected to the surface of the piston housing 701.

[0029] The protective shell 9 is made of high-strength engineering plastics such as polystyrene, which has good wear resistance, toughness and impact resistance, and can withstand a certain amount of external force without being damaged; The piston housing 701 is the main structure of the piston mechanism 7. The pressure block 703 has through holes with a diameter of 1 mm on both sides at the upper end. When the pressure block 703 is pressed down, it compresses the plastic spring 702 and at the same time creates a closed space inside the piston housing 701 to generate negative pressure. The air chamber passes through the water outlet channel, and finally the liquid is ejected from the through holes on the pressure block 703.

[0030] Please see Figure 1 , 5 The bottom of the inner wall of the connecting plug 8 is provided with anti-theft teeth 10, which are arranged in a ring array with the center of the connecting plug 8.

[0031] The inner lining of the connecting plug 8 is equipped with anti-theft teeth 10, which interlock with the anti-theft ring or the protrusion on the bottle to form a stable connection, preventing the nozzle from rotating or falling off, while also increasing the difficulty of disassembly.

[0032] Please see Figures 1-2 The nozzle housing 1 has anti-slip protrusions 11 fixedly connected to one side of both the front and back sides. The anti-slip protrusions 11 are made of rubber.

[0033] The anti-slip bumps 11, located on both sides of the nozzle, facilitate convenient adjustment of the spray angle by the user with one hand. Simultaneously, the raised particles or textures significantly increase the friction between the fingers and the nozzle surface, especially when hands are wet, have detergent on them, or are wearing gloves. The anti-slip bumps 11 prevent fingers from slipping, ensuring a stable grip and operation of the nozzle. Furthermore, the anti-slip bumps 11 are made of rubber, which is soft and possesses excellent elasticity and deformation capacity. When pressed by a finger, the rubber bumps undergo slight deformation, increasing the contact area and cushioning pressure on the skin, avoiding the discomfort that can occur with hard plastic.

[0034] The working principle of this utility model is as follows: First, after installing the nozzle on the spray bottle, hold the spray bottle body with one hand where you can grip it, press the handle 4 inward, and the plastic block 5 will be squeezed backward. The pressure valve adjustment mechanism 6 will make an adaptive bending adjustment, and the pressure block 703 will form a closed space with the piston housing 701 vertically downward. The liquid will be squeezed out of the nozzle 2 by negative pressure. Secondly, the user's other hand fingers grip the lever 304 and move it horizontally forward or backward. At the same time, the connecting rod 303 makes mechanical movement, and the fixing block 302 and the drainage tube 301 are rotated, so that the spray angle of the drainage tube 301 is changed. The user can slightly adjust the bending angle of the arm to avoid the arm soreness caused by repeatedly and significantly adjusting the bending angle of the wrist.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
