Description

Technical Field

[0001] This utility model relates to the field of industrial nozzle technology, specifically a quick-disassembly industrial nozzle device. Background Technology

[0002] Industrial nozzles are mostly installed in various spraying, misting, oil spraying, sandblasting, and coating equipment, playing different roles.

[0003] When existing nozzles need to be disassembled and maintained, their connection method is generally to rotate the nozzle to the end of the connecting pipe. When disassembly is required, the nozzle needs to be completely rotated to disengage from the threaded connection of the connecting pipe. However, the number of turns of the thread basically determines the sealing performance between the nozzle and the nozzle pipe. Therefore, disassembly with multiple turns consumes time and reduces work efficiency. Utility Model Content

It solves the problem that when existing nozzles need to be disassembled and maintained, their connection method is generally to rotate the nozzle to the end of the connecting pipe. When disassembly is required, the nozzle needs to be completely rotated to disengage from the threaded connection of the connecting pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-2 This utility model discloses a quick-disassembly industrial nozzle device, including a connecting pipe 1, a nozzle 2 connected to the lower part of the connecting pipe 1, and a disassembly and installation assembly 3 installed between the connecting pipe 1 and the nozzle 2, wherein:

[0024] The disassembly and installation assembly 3 includes an extension plate 30, which is installed on the outer surface of the connecting pipe 1. Side plates 31 are installed on both sides of the extension plate 30. A groove 32 is provided on the inner wall of the side plate 31. A threaded rod 33 and a limiting rod 34 are installed on the inner wall of the groove 32. A slider 35 is installed on the outer surface of the threaded rod 33 and the limiting rod 34. A connecting plate 36 is installed on one side of the slider 35. An arc plate 37 is installed on one side of the connecting plate 36. A protrusion 38 is installed on the top surface of the nozzle 2 and the bottom surface of the connecting pipe 1. A rubber ring 39 is installed on the outer surface of the protrusion 38.

[0025] The bottom surface of the connecting tube 1 is fixedly connected to the top surface of the protrusion 38, the inner wall of the connecting tube 1 is inserted into the upper part of the nozzle 2, and there are two extension plates 30.

[0026] One side of each of the two extension plates 30 is fixedly connected to the outer surface of the connecting pipe 1, and both sides of each extension plate 30 are fixedly connected to one side of a side plate 31. A groove 32 is provided on one side of each side plate 31.

[0027] When nozzle 2 needs to be disassembled, the threaded rod 33 is rotated in the opposite direction. Under the rotation of the threaded rod 33, the slider 35 moves in the opposite direction along the axial direction, causing the connecting plate 36 and the arc plate 37 to move away from the protrusion 38. After the arc plate 37 is completely disengaged from the protrusion 38, the nozzle 2 can be pulled out from under the connecting pipe 1, completing the disassembly operation. Example 2

[0028] Based on the above embodiment 1, please refer to Figures 3-5 The threaded rod 33 consists of two equidistant rotatable connections to the inner wall of the slide groove 32. Two limiting rods 34 are provided on the opposite side of the threaded rod 33. The outer surface of the limiting rod 34 is movably inserted into the two slide grooves 32 on one side.

[0029] Both the outer surfaces of the threaded rod 33 and the limiting rod 34 are rotatably connected to sliders 35, and the outer surface of sliders 35 slides in contact with the inner wall of the groove 32.

[0030] One side of each slider 35 is fixedly connected to a connecting plate 36, and one side of every two connecting plates 36 is fixedly connected to the outer surface of an arc plate 37.

[0031] The inner walls of the two arc plates 37 are interlocked with the outer surface of the protrusion 38, the top surface of the protrusion 38 is fixedly connected with the bottom surface of the connecting pipe 1, the inner wall of the protrusion 38 is interlocked with the upper part of the nozzle 2, and the middle part of the outer surface of the protrusion 38 is fixedly connected with each other.

[0032] As the threaded rod 33 rotates, the slider 35, connected to the threaded rod 33 by a thread, moves axially along the threaded rod 33 during rotation. Simultaneously, the limiting rod 34 restricts the direction of rotation of the slider 35, ensuring it can only slide axially. With the movement of the slider 35, the arc plate 37 gradually approaches and inserts into the outer surface of the protrusion 38 until they are tightly engaged. At this point, the rubber ring 39 is compressed, providing sealing and cushioning, thus completing the installation of the nozzle 2 and the connecting pipe 1.

[0033] The working principle and usage process of this utility model are as follows: First, the upper part of the nozzle 2 is aligned with the inner wall of the connecting pipe 1 and inserted, so that the nozzle 2 is initially installed below the connecting pipe 1.

[0034] Next, observe the two extension plates 30, and the sliding grooves 32 opened on the side plates 31 connected to both sides of each extension plate 30. Since the threaded rod 33 and the limiting rod 34 are movably installed in the sliding groove 32, and the slider 35 is movably sleeved on the outside of the threaded rod 33 and the limiting rod 34 and slides in contact with the inner wall of the sliding groove 32, the slider 35 can be manually pushed at this time. The slider 35 drives the connecting plate 36 to move, and the connecting plate 36 then drives the arc plate 37 to move, so that the inner walls of the two arc plates 37 are respectively aligned with the protrusions 38 on the bottom surface of the connecting pipe 1 and the top surface of the nozzle 2.

[0035] Then, the threaded rod 33 is rotated. Since the slider 35 and the threaded rod 33 are threadedly connected, the slider 35 will move along the axial direction of the threaded rod 33 during the rotation of the threaded rod 33. At the same time, the limiting rod 34 restricts the rotation direction of the slider 35, ensuring that the slider 35 can only slide along the axial direction. As the slider 35 moves, the arc plate 37 gradually approaches and inserts into the outer surface of the protrusion 38 until the arc plate 37 and the protrusion 38 are tightly inserted. At this time, the rubber ring 39 is compressed, which plays a sealing and buffering role, completing the installation of the nozzle 2 and the connecting pipe 1.

[0036] Disassembly stage: When nozzle 2 needs to be disassembled, rotate threaded rod 33 in the opposite direction. Under the rotation of threaded rod 33, slider 35 moves in the opposite direction along the axial direction, causing connecting plate 36 and arc plate 37 to move away from protrusion 38. After arc plate 37 is completely disengaged from protrusion 38, nozzle 2 can be pulled out from under connecting pipe 1, completing the disassembly operation.
