Description

Technical Field

[0001] The utility model relates to the technical field of nozzle connection, in particular to a connection structure for a nozzle. Background Art

[0002] Nozzles are a key component in many types of spraying, misting, oiling, sandblasting, and coating equipment, and play an important role. Nozzles are widely used in the industry, with materials ranging from stainless steel and plastic to silicon carbide, polytetrafluoroethylene, PP (polypropylene), aluminum alloy, and tungsten steel. They are commonly used in various industries such as automobiles, electroplating, surface treatment, high-pressure cleaning, dust removal, cooling, desulfurization, humidification, mixing, and gardening.

[0003] The accessories of the nozzle include pipe thread joint accessories, solenoid valves, liquid filters and pressure gauge joints. The main material of the pipe thread joint is stainless steel, and the thread connection method can be divided into internal thread connection and external thread connection.

[0004] Existing nozzles are fixed using a single internal and external thread connection method. During long-term use, when the nozzle is in an environment with a high vibration frequency, the threads will loosen due to the vibration force, which will affect the stability of the nozzle connection. In view of this, we propose a connection structure for the nozzle. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present invention provides a nozzle connection structure that solves the problems raised in the above-mentioned background art. To achieve the above objectives, the present invention is implemented through the following technical solutions: a nozzle connection structure comprising a nozzle body, a connecting sleeve being threadedly connected to the upper portion of the nozzle body, and a magnetic plug-in positioning device provided on the nozzle body, the magnetic plug-in positioning device being used to achieve multiple fixed connections between the nozzle body and the connecting sleeve.

[0006] Preferably, the magnetic plug-in positioning device includes a fixed base, the surface of the fixed base is fixedly connected to the nozzle body, a slide groove is provided inside the fixed base, a magnetic plug rod is slidably connected inside the slide groove, and the end of the magnetic plug rod is plugged into the mounting base.

[0007] Preferably, the surface of the mounting base is fixedly connected to the connecting sleeve, and a socket is provided inside the mounting base.

[0008] Preferably, the surfaces of the magnetic rod are fixedly connected with a front magnetic ring and a rear magnetic ring respectively, the interiors of the slide groove and the socket are fixedly connected with an iron ring, and the surface of the rear magnetic ring is magnetically connected to the inner wall of the iron ring.

[0009] Preferably, a limit plate is fixedly connected to the surface of the magnetic rod near the rear magnetic ring, and a connecting tube is fixedly connected to one end of the magnetic rod away from the rear magnetic ring.

[0010] Preferably, the nozzle body comprises a nozzle, a spray hole and a connecting pipe, the end of the nozzle is fixedly connected to the end of the connecting pipe, and the spray hole is provided at an end of the nozzle away from the connecting pipe.

[0011] Preferably, a thread groove is provided on the inner wall of the connecting sleeve, and the interior of the connecting sleeve is threadedly connected to the surface of the connecting pipe.

[0012] As can be seen from the above technical solutions, the nozzle connection structure provided in the embodiments of this specification has at least the following beneficial effects:

[0013] (1) The utility model uses a magnetic plug-in positioning device to manually move the magnetic plug rod after the nozzle body and the connecting sleeve are threadedly installed. During the insertion, the magnetic plug rod drives several other magnetic plug rods to move through the connecting pipe. Multiple magnetic plug rods inserted into multiple sockets can achieve the purpose of positioning the connecting pipe and the connecting sleeve. After the connecting pipe and the connecting sleeve are initially threadedly connected, secondary plug-in fixation is achieved to improve the stability of the overall installation connection of the nozzle body.

[0014] (2) The utility model allows the operator to move the magnetic rod before installing the connecting pipe and the connecting sleeve, so that the magnetic rod moves toward the nozzle. After the movement, the rear magnetic ring end of the magnetic rod does not contact or interfere with the installation base. Moreover, the front magnetic ring is located on the inner wall of the slide groove, and is magnetically positioned by the magnetic force and the iron ring inside the slide groove, thereby ensuring that when the nozzle is rotated later, the magnetic rod does not contact or interfere with the installation base, and the stability of the position positioning can be maintained. After the connecting pipe and the connecting sleeve are threadedly installed, the operator manually moves the magnetic rod with a force greater than the limit of the front magnetic ring, and controls the rear magnetic ring end of the magnetic rod to be inserted into the socket. The rear magnetic ring can be fixed to the iron ring in the socket by magnetic force, further increasing the magnetic force, and achieving the effect of multiple fixing of the connecting pipe and the connecting sleeve.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-Figure 5 As shown, a connection structure for a nozzle includes a nozzle body 1, a connecting sleeve 2 is connected to the upper thread of the nozzle body 1, and a magnetic plug-in positioning device 3 is provided on the nozzle body 1. The magnetic plug-in positioning device 3 is used to perform multiple fixed connections between the nozzle body 1 and the connecting sleeve 2.

[0025] In this embodiment, the magnetic insertion and positioning device 3 includes a fixed base 31. The surface of the fixed base 31 is fixedly connected to the nozzle body 1. A slot 32 is defined within the fixed base 31. A magnetic rod 33 is slidably connected within the slot 32. The end of the magnetic rod 33 is inserted into a mounting base 34. The surface of the mounting base 34 is fixedly connected to the connecting sleeve 2. The mounting base 34 defines a socket 35. After the connecting tube 13 and the connecting sleeve 2 are threaded together, the operator manually moves the magnetic rod 33 to control its insertion into the socket 35. During insertion, the magnetic rod 33 drives the movement of several other magnetic rods 33 via the connecting tube 310. Multiple magnetic rods 33 inserted into multiple sockets 35 can effectively position the connecting tube 13 and the connecting sleeve 2. After the initial threaded connection between the connecting tube 13 and the connecting sleeve 2, a secondary insertion and fixing is achieved, thereby improving the stability of the overall installation connection of the nozzle body 1.

[0026] Furthermore, the surfaces of the magnetic rod 33 are fixedly connected to the front magnetic ring 36 and the rear magnetic ring 37 respectively, and the interior of the slide groove 32 and the socket 35 are fixedly connected to the iron ring 38, and the surface of the rear magnetic ring 37 is magnetically connected to the inner wall of the iron ring 38. The operator moves the magnetic rod 33 before installing the connecting pipe 13 and the connecting sleeve 2, so that the magnetic rod 33 moves toward the spray hole 12. After the movement, the rear magnetic ring 37 end of the magnetic rod 33 does not contact or interfere with the mounting base 34. Moreover, at this time, the front magnetic ring 36 is located on the inner wall of the slide groove 32, and is magnetically positioned with the iron ring 38 inside the slide groove 32 by magnetic force, thereby ensuring that when the nozzle 11 is rotated later, the magnetic rod 33 does not contact or interfere with the mounting base 34, and at the same time can maintain the stability of the position positioning. After the connecting pipe 13 and the connecting sleeve 2 are threadedly installed, the operator manually moves the magnetic rod 33. The moving force is greater than the limit of the front magnetic ring 36, and the rear magnetic ring 37 end of the magnetic rod 33 is controlled to be inserted into the socket 35. The rear magnetic ring 37 can use magnetic force to fix it at the iron ring 38 in the socket 35, further increasing the magnetic force, thereby achieving the effect of multiple fixation of the connecting pipe 13 and the connecting sleeve 2.

[0027] Furthermore, the surface of the magnetic rod 33 is fixedly connected to the limit plate 39 near the rear magnetic ring 37, and the end of the magnetic rod 33 away from the rear magnetic ring 37 is fixedly connected to the setting of the connecting tube 310, so that moving any one of the magnetic rods 33 can drive the other rear magnetic rings 37 to move synchronously, thereby achieving the purpose of rapid insertion, positioning and movement.

[0028] Example 2

[0029] See also Figure 1-Figure 5 As shown, the nozzle body 1 includes a nozzle 11, a nozzle hole 12 and a connecting pipe 13. The end of the nozzle 11 is fixedly connected to the end of the connecting pipe 13, and the nozzle hole 12 is opened at the end of the nozzle 11 away from the connecting pipe 13.

[0030] Furthermore, a thread groove is provided on the inner wall of the connecting sleeve 2, and the interior of the connecting sleeve 2 is threadedly connected to the surface of the connecting pipe 13.

[0031] When the nozzle 11 is rotated laterally, the magnetic rod 33 does not contact and interfere with the mounting base 34, and the stability of the position positioning is maintained. When the connecting tube 13 and the connecting sleeve 2 are threadedly installed, the operator manually moves the magnetic rod 33 to move the nozzle hole 12. The dynamic force is greater than the limit of the front magnetic ring 36, and the rear magnetic ring 37 end of the magnetic plug rod 33 is controlled to be inserted into the socket 35. During the insertion, the magnetic plug rod 33 drives the other several rear magnetic rings 37 to move synchronously through the connecting tube 310. After the rear magnetic ring 37 is inserted into the socket 35, it has a plug-in effect. Multiple magnetic plug rods 33 are inserted into multiple sockets 35 to achieve the purpose of positioning the connecting pipe 13 and the connecting sleeve 2. After the connecting pipe 13 and the connecting sleeve 2 are initially threaded together, a secondary plug-in fixation is achieved, thereby improving the stability of the overall installation connection of the nozzle body 1. At the same time, the rear magnetic ring 37 can be fixed to the iron ring 38 in the socket 35 by magnetic force, further increasing the magnetic force, and achieving the effect of multiple fixing of the connecting pipe 13 and the connecting sleeve 2. The plug-in and magnetic connection methods are used instead of the traditional single threaded connection method of the nozzle, thereby further achieving the effect of improving the stability of the nozzle connection structure. At the same time, the operation is convenient, and the effect of quick connection and disassembly is achieved.

[0032] The above implementation methods are only used to illustrate the embodiments of the present invention, and are not intended to limit the embodiments of the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the embodiments of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the embodiments of the present invention, and the scope of patent protection of the embodiments of the present invention should be defined by the claims.
