Description

Technical Field

[0001] This utility model relates to the field of water spraying system technology, specifically to a water nozzle fixing device and a water nozzle. Background Technology

[0002] Water spray nozzles used in road or rail transit water systems are primarily fixed to the side or end of vehicles using pipe clamps. They are used to rinse away dirt and grime from roadside equipment or tunnel walls. These pipe clamps are typically welded in place, and once their position is determined, the orientation of the spray nozzle is fixed. This fixed installation position limits the range of motion of the spray nozzle. The orientation of the nozzle determines the direction of the water flow, thus affecting the effectiveness and quality of the cleaning process. Summary of the Invention

[0003] This utility model provides an adjustable spray nozzle fixing device for fixing and installing spray nozzles in a water system, and can be appropriately installed and adjusted according to the required spray angle of the spray nozzle.

[0004] The technical solution of this utility model is: an adjustable spray nozzle fixing device, including a transition joint and a clamping assembly for clamping the transition joint; the transition joint has an a connection port for connecting a water supply pipe and a b connection port for connecting a spray nozzle; the clamping assembly includes two opposing clamping plates and a connector for fastening the two clamping plates, and an adjustable fixing seat is provided on one clamping plate.

[0005] The adjustable fixing seat includes a stud and a nut that mates with the stud. There are two nuts arranged side by side. One nut is a fastening nut, and the other nut is a backup nut, which is located outside the fastening nut.

[0006] The outer wall of the transition joint's a-connection port has a hexagonal structure, while the outer wall of the b-connection port has a cylindrical structure. A shoulder is provided between the a-connection port and the b-connection port.

[0007] The inner cavity of the transition joint is a through hole with threads at both ends.

[0008] The connector is a screw. One clamping plate has a threaded countersunk hole, and the other clamping plate has a countersunk screw mounting hole. The threaded countersunk hole and the countersunk screw mounting hole are combined to form a mounting hole that mates with the screw for installation.

[0009] The screws and mounting holes are both two or more, and the screws are installed in the mounting holes via spring washers.

[0010] The two opposing clamping plates have grooves on their inner sides, and the grooves on the inner sides of the two clamping plates together form a positioning cavity that is adapted to the cylindrical structure of the transition joint.

[0011] When the two opposing clamping plates are connected as one piece by a connector, the opposite end faces of the two clamping plates are in clearance fit.

[0012] An adjustable fixing seat is provided on the outside of the clamp to form a T-shaped fixing clamp. The outside of the T-shaped fixing clamp is a stud. The stud and the nut that mates with the stud form an adjustable fixing seat.

[0013] An adjustable spray nozzle includes a spray nozzle and an adjustable spray nozzle fixing device as described above for mounting the spray nozzle.

[0014] The beneficial effects of this utility model are: by using an adjustable nozzle fixing device, the nozzle has a large degree of freedom in adjusting the angle at the installation position, which makes it convenient to adjust the spray direction of the nozzle. The device has a simple structure, is easy to install and adjust, has good applicability, and has strong versatility. It can be promoted and used in water systems in engineering machinery fields such as roads or rail transit. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings. This embodiment is only used to explain the present invention and does not constitute a limitation on the scope of protection of the present invention.

[0020] like Figure 1 , Figure 2 As shown, the fixing device of this utility model includes a T-shaped fixing clip 2, a clamping plate 4, and a transition joint 3, which is fixedly clamped and installed by two screws. The a-connection port of the transition joint 3 is connected to the water supply pipe, and the b-connection port of the transition joint 3 is connected to the spray nozzle 8. The T-shaped tail of the T-shaped fixing clip 2 is a threaded stud, which is fastened with a nut 1 to clamp and fix the T-shaped fixing clip 2. The nut 1 is installed and fixed on the hole of the plate 7. By adjusting the orientation of the T-shaped fixing clip 2, the angle of the transition joint 3 is changed, thereby changing the spray direction of the nozzle.

[0021] The adjustable spray nozzle fixing device uses a threaded stud at the tail of the T-shaped fixing clamp 2, which cooperates with the nut 1 to fix it in the hole of the plate 7. Two nuts 1 are provided; the nut 1 installed near the plate 7 provides the fixing force after the T-shaped fixing clamp 2 and the plate 7 are adjusted in angle, while the outer nut 1 prevents the inner nut 1 from loosening and avoids changes in the fixing angle of the T-shaped fixing clamp 1. The head of the T-shaped fixing clamp 2 has two threaded countersunk holes with a semi-circular groove in the middle, which cooperate with the transition joint 3 and the clamp plate 4. The clamp plate 4 has two countersunk screw mounting holes that cooperate with the two threaded countersunk holes at the head of the T-shaped fixing clamp 2 to install spring washers 5 and screws 6. The middle part of the clamp plate 4 is also semi-circularly grooved, which, together with the semi-circular groove in the middle of the head of the T-shaped fixing clamp 2, forms a circle. It also has a gap c for compensating for and securing the transition joint 3, providing a certain clamping force.

[0022] The a-connection end of the transition joint 3 adopts a hexagonal structure to facilitate the clamping and tightening of the wrench during the installation of pipelines and spray nozzles. The b-connection end adopts a cylindrical structure with a shoulder in the middle, which facilitates the installation and positioning of the transition joint 3, and also helps the T-shaped fixing clamp 2 and clamping plate 4 to prevent loosening and slippage of the transition joint 3 during installation.

[0023] like Figure 3 As shown, the actual application method is as follows: The tail stud of the T-shaped fixing clip 2 of the adjustable spray nozzle fixing device passes through the hole in the plate 7, and the two nuts 1 are installed on the stud respectively. Connect the water supply pipeline to the a-connection port end of the transition joint 3, and install the spray nozzle 8 on the b-connection port end of the transition joint 3. Fix the shoulder of the transition joint 3 to the T-shaped fixing clip 2 using the clamp 4. First, adjust the orientation of the transition joint 3 according to the required angle of the spray nozzle. After determining the spray angle of the spray nozzle 8, start tightening from the nut 1 closest to the plate 7. Tighten the two nuts 1 one by one, and the spray nozzle fixing device is adjusted into place.

[0024] The preferred water nozzle 8 is a water nozzle with a ball joint. After the water nozzle fixing device is adjusted to the correct position, the ball joint of the water nozzle can be finely adjusted to further optimize the spray direction of the water nozzle, so as to obtain a better spray effect.

[0025] The above description, in conjunction with the accompanying drawings, is merely a description of one specific embodiment of the present utility model and does not limit the technical solution of the present utility model thereto. All equivalent changes or modifications to the appearance made in accordance with the spirit and essence of the present utility model shall fall within the protection scope of the present utility model.
