Technical Field
[0001] This utility model relates to the field of spray nozzle technology, specifically to a spray nozzle that is easy to install and remove. Background Technology
[0002] In industrial production, spray nozzles are widely used in various fluid transport and spraying operations, such as spraying, cleaning, and cooling.
[0003] Traditional spray nozzles are typically fixed to pipeline equipment by welding or threading;
[0004] Although threaded connections offer a certain degree of safety and sealing, their installation and removal process is rather cumbersome, especially in situations where space is limited. In addition, frequent installation and removal can easily lead to thread wear, affecting the sealing effect and service life.
[0005] While welding provides strong structural stability and good sealing performance, disassembly becomes extremely difficult once welded, and re-welding is required whenever replacement or repair is needed, increasing maintenance costs and time. Furthermore, the thermal stress that may be generated during welding can affect the physical properties of the nozzle and pipe materials.
[0006] Therefore, the existing connection method makes the maintenance of the nozzle difficult, which requires a nozzle that is easy to install and remove. Utility Model Content
[0007] The technical problem this invention aims to solve is that the nozzle is difficult to maintain, and it provides a spray nozzle that is easy to install and remove.
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a spray nozzle that is easy to install and remove, including a spray nozzle body and an installation pipe;
[0009] The nozzle body is connected to the installation pipe via a quick-connect fitting.
[0010] The quick-connect fitting includes a male and a female connector. The male connector is installed at one end of the nozzle body, and the female connector is installed at the interface of the installation pipe. A self-locking mechanism is set inside the quick-connect fitting, which automatically locks after the male connector is inserted into the female connector.
[0011] As an improvement, the female head is a cylindrical tube, one end of which is fixedly connected to the installation pipe, and the inner cavity has a flow channel communicating with the installation pipe. The male head is a cylindrical tube, one end of which is fixedly connected to the nozzle body, and the inner cavity has a flow channel communicating with the nozzle body.
[0012] As an improvement, the male head has a tapered guide section at the end near the female head, and the inner wall of the female head has a tapered hole that matches the tapered guide section. After the male head is inserted into the female head, the tapered guide end fits into the tapered hole.
[0013] As an improvement, the self-locking mechanism includes a spring latch and a slot;
[0014] The outer wall of the male end is provided with a pair of spring clips located at the edge of the tapered guide section. When the male end is inserted into the female end, the spring clips automatically pop out and lock into the slot of the female end.
[0015] As an improvement, after the male head is placed close to the female head, annular grooves are respectively opened on the outer wall of the male head and the conical guide section close to the female head, and sealing rings are installed in the annular grooves respectively.
[0016] As an improvement, a guiding and positioning mechanism is also included; the guiding and positioning mechanism includes a guide groove and a positioning pin;
[0017] The male connector has a locating pin on its outer wall, and a guide groove that mates with the locating pin is provided at the end of the female connector. When the male connector is fully inserted into the female connector, the locating pin enters the guide groove of the female connector.
[0018] The advantages of this utility model compared with the prior art are as follows:
[0019] 1. It adopts a quick-connect coupling, which includes a male and a female part. The male part is installed at one end of the nozzle, and the female part is installed at the pipe interface. The nozzle can be installed and removed by simple insertion and removal operations without the need for tools, which greatly improves work efficiency.
[0020] 2. A self-locking mechanism is installed inside the quick-connect connector. When the male connector is inserted into the female connector, the self-locking mechanism automatically locks to prevent accidental dislodgement and ensure the stability and safety of the system.
[0021] 3. The sealing ring effectively prevents fluid leakage, ensures the system's sealing performance, and is suitable for conveying various media;
[0022] 4. Guide grooves and positioning pins are set at the interface between the male and female connectors to ensure that the male connector can be accurately aligned and smoothly inserted into the female connector, thereby improving installation accuracy and reducing the possibility of misoperation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.
[0031] Example 1
[0032] A spray nozzle that is easy to install and remove includes a spray nozzle body 1 and an installation pipe 2. The spray nozzle body 1 and the installation pipe 2 are connected by a quick-connect coupling. The quick-connect coupling includes a male connector 3 and a female connector 4. The male connector 3 is installed at one end of the spray nozzle body 1, and the female connector 4 is installed at the interface of the installation pipe 2. The female connector 4 is a cylindrical tube. After one end is fixedly connected to the installation pipe 2, its inner cavity has a flow channel communicating with the installation pipe 2. The male connector 3 is a cylindrical tube. After one end is fixedly connected to the spray nozzle body 1, its inner cavity has a flow channel communicating with the spray nozzle body 1. The male connector 3 has a tapered guide section 5 near the female connector 4. The inner wall of the female connector 4 has a tapered hole 6 that matches the tapered guide section 5. After the male connector 3 is inserted into the female connector 4, the tapered guide end fits into the tapered hole 6. After the male connector 3 is placed close to the female connector 4, the outer wall of the male connector 3 and the tapered guide section 5 close to the female connector 4 respectively has annular grooves 9. Sealing rings are installed in the annular grooves 9 respectively.
[0033] When produced in the factory, the male head 3 and the main body 1 of the injection nozzle are an integral structure. When in use, the female head 4 is fixedly connected to the installation pipe 2 and other equipment (welding and flange connection, etc.). Then, the male head 3 is pushed close to the female head 4 so that the tapered guide section 5 is completely inserted into the tapered hole 6.
[0034] A self-locking mechanism is set inside the quick-connect connector. After the male connector 3 is inserted into the female connector 4, the self-locking mechanism automatically locks. The self-locking mechanism includes a spring clip 7 and a slot 8. The outer wall of the end of the male connector 3 is provided with a pair of spring clips 7 located at the edge of the tapered guide section 5. When the male connector 3 is inserted into the female connector 4, the spring clips 7 automatically pop out and lock into the slot 8 of the female connector 4 (the end of the spring clip 7 has an outwardly protruding clip head. The front end of the clip head is designed with an inclined surface to facilitate compression of the clip head during insertion and reduce resistance. When the male connector 3 is inserted into the female connector 4, the clip head is squeezed inward by the inner wall of the female connector 4. When the clip head moves to the position of the slot 8, it automatically pops out and locks into the slot 8 under the action of the spring restoring force, forming a self-locking state. If you want to pull it out, you need to manually press the clip to make it disengage from the slot 8 and then pull out the male connector 3).
[0035] When the tapered guide section 5 of the male head 3 is fully inserted into the tapered hole 6, the self-locking structure is automatically activated, and the spring buckle 7 automatically pops out and enters the slot 8 to achieve quick locking.
[0036] Example 2
[0037] It also includes a guide positioning mechanism; the guide positioning mechanism includes a guide groove 10 and a positioning pin 11; the outer wall of the male head 3 is provided with a positioning pin 11, and the end of the female head 4 is provided with a guide groove 10 that cooperates with the positioning pin 11. When the male head 3 is fully inserted into the female head 4, the positioning pin 11 enters the guide groove 10 of the female head 4, ensuring that the male head 3 can be accurately aligned and smoothly inserted into the female head 4, improving installation accuracy and reducing the possibility of misoperation.
[0038] In the specific implementation of this utility model, the user first aligns the male head 3 on the nozzle body 1 with the female head 4 at the interface of the installation pipe 2, and then pushes it axially until a "click" is heard, indicating that the spring clip 7 has successfully engaged in the slot 8 and completed the locking. At this time, due to the cooperation between the tapered guide section 5 and the tapered hole 6 and the effect of the sealing ring, a good sealing effect is achieved. When it is necessary to remove it, simply press down to retract the spring clip 7, and the male head 3 can be easily pulled out.
[0039] 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 inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
