[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] Please refer to Figure 1 and Figure 2 As shown, the present invention provides a quick-plug and pull-out glue spray nozzle.

[0037] The joint column 1 includes a joint ring 2, wherein a glue spray nozzle 11 is provided on the joint column 1, and an assembly hole is provided at the center of the joint ring 2. The joint ring 2 is embedded in the assembly hole along the direction of the glue spray nozzle 11. When set, the glue spray nozzle 11 is located at the center of the joint column 1.

[0038] A first docking portion 13 is provided on the side wall of the joint column 1 , and a second docking portion is provided on the side wall of the docking ring body 2 . The first docking portion 13 fits with the second docking portion so that the docking ring body 2 is stably installed on the joint column 1 .

[0039] A locking assembly is also provided on the side wall of the docking ring body 2, and the locking assembly is used to lock the first docking portion 13 with the second docking portion.

[0040] During implementation, the first docking portion 13 on the connector column 1 is matched with the second docking portion on the docking ring body 2, so that the connector column 1 is connected to the docking ring body 2. In addition, the locking assembly can make the connection between the connector column 1 and the docking ring body 2 more stable or easier to separate. There are many ways to match the first docking portion 13 and the second docking portion, such as threaded connection, block and slot connection, or elastic structure such as rubber ring, etc. As long as the matching structure can stably install the docking ring body 2 on the connector column 1, it can be applied.

[0041] As a preferred embodiment, in this embodiment, the first docking portion 13 has an annular groove structure, and the cross section of the groove structure is an arc shape. The first docking portion 13 is an annular groove arranged on the outer side wall of the joint column 1, so that the second docking portion is buckled in the annular groove, which plays a role in fixing the joint column 1 and the docking ring 2.

[0042] Further, the second docking portion includes at least two stop balls 22 and a docking hole 21 corresponding to the stop balls 22 . The docking hole 21 is arranged on the side wall of the docking ring body 2 , and the stop balls 22 are arranged in the docking hole 21 .

[0043] When the first docking portion 13 is locked with the second docking portion, the stop ball 22 passes through the corresponding docking hole 21 and is partially located in the first docking portion 13. In practice, part of the stop ball 22 falls into the groove of the first docking portion 13, and the stop ball 22 is locked by the locking assembly, so that the docking ring body 2 is stably installed on the joint column 1.

[0044] When the first docking portion 13 is separated from the second docking portion, the stop ball 22 is separated from the first docking portion 13 and partially located in the docking hole 21. In practice, the stop ball 22 is not limited by the locking assembly, and the stop ball 22 can move. The part of the stop ball 22 that falls into the groove of the first docking portion 13 is squeezed out, and the docking ring body 2 is separated from the joint column 1, and the disassembly and assembly are extremely convenient.

[0045] Furthermore, the plurality of docking holes 21 are evenly distributed along the circumferential direction of the docking ring body 2. The evenly distributed docking holes 21 ensure that when the joint column 1 is connected to the docking ring body 2, the extrusion force in the circumferential direction is even.

[0046] Furthermore, the diameter of the docking hole 21 is smaller than the diameter of the stop ball 22. This can prevent the stop ball 22 from completely passing through the docking hole 21 and falling into the first docking portion 13, thereby directly affecting the connection between the joint column 1 and the docking ring body 2; in addition, it can also ensure that when the stop ball 22 is locked, the stop ball 22 is always at the center of the docking hole 21.

[0047] like Figure 2 As shown, the locking assembly can be used in a variety of structures, such as a method of tightening with an elastic ring such as a rubber ring. When locking, the rubber ring tightens the position where the stop ball 22 is located; when separating, the elastic ring such as the rubber ring is taken out, and the stop ball 22 is separated from the docking hole 21, so that the joint column 1 and the docking ring 2 can be separated. As a preferred embodiment, the locking assembly in this embodiment includes a ferrule 31 and an elastic member 32.

[0048] The ferrule 31 is annular and is sleeved on the outer circumference of the docking ring body 2 . The elastic member 32 connects the ferrule 31 to the docking ring body 2 .

[0049] A receiving cavity is provided on one side of the ferrule 31 that is in contact with the joint column 1 , and a portion of the stop ball 22 that protrudes from the outer periphery of the docking ring body 2 is located in the receiving cavity.

[0050] During implementation, the accommodating cavity of the ferrule 31 frames the stop ball 22 to prevent the possibility of instability caused by the stop ball 22 rolling down during use; in addition, the ferrule 31 and the docking ring body 2 are connected by the elastic member 32, so that the ferrule 31 should reciprocate along the circumferential surface of the docking ring body 2 to lock or separate the first docking part 13 and the second docking part.

[0051] Furthermore, the accommodating cavity consists of a disengagement section 311 and an embedding section 312 . The cross section of the disengagement section 311 has a rectangular structure, and the cavity depth of the disengagement section 311 is smaller than the diameter of the stop ball 22 . The embedding section 312 is used to push the stop ball 22 into the groove of the first docking portion 13 .

[0052] The embedding section 312 and the disengaging section 311 are connected to each other, and the cavity depth of the embedding section 312 gradually decreases in a direction away from the disengaging section 311 .

[0053] During implementation, when the first docking part 13 is locked with the second docking part, the embedded section 312 of the ferrule 31 contacts the stop ball 22 under the action of the elastic member 32. Since the cavity depth of the embedded section 312 gradually decreases in the direction away from the disengagement section 311, the embedded section 312 squeezes the stop ball 22 into the annular groove of the first docking part 13, thereby locking the first docking part 13 with the second docking part.

[0054] When the first docking part 13 is disengaged from the second docking part, the sleeve 31 is pressed against and squeezed in the direction of the elastic member 32, so that the stop ball 22 moves away from the embedded section 312 and enters the disengagement section 311. Since the disengagement section 311 does not squeeze the stop ball 22, the stop ball 22 can be squeezed out of the first docking part 13, thereby allowing the docking ring body 2 to be pulled out from the connector column 1.

[0055] The cavity depth referred to in the present invention is only the height of the detachment section 311 and the embedding section 312 perpendicular to the circumferential surface of the docking ring body 2. When set, the cavity depth of the detachment section 311 is smaller than the diameter of the stop ball 22, which can prevent the stop ball 22 from completely detaching from the docking hole 21.

[0056] Furthermore, the elastic member 32 of the present invention can be a spring, rubber or other elastic structure. In this embodiment, the elastic member 32 is a spring, one end of which is connected to one end of the ferrule 31 adjacent to the embedded section 312 in a transverse direction.

[0057] One end of the docking ring body 2 is provided with an end cap 23, the diameter of the end cap 23 is larger than the diameter of the docking ring body 2, and the other end of the spring is fixed to the end cap 23. When set, the spring is connected to the portion of the end cap 23 that exceeds the docking ring body 2, so that the ferrule 31 fits the circumferential surface of the docking ring body 2.

[0058] Furthermore, the end cap 23 is provided with a glue spray hole 231 that matches the glue spray nozzle 11. The glue spray hole 231 is provided on the end cap 23, and the glue spray nozzle 11 passes through the glue spray hole 231, which can prevent the glue from contaminating the joint column 1 or other parts of the docking ring body 2 when the glue spray nozzle 11 is working.

[0059] Furthermore, a plurality of corresponding air outlet holes 12 are provided around the glue spraying nozzle 11 on the joint column 1 and around the glue spraying hole 231 on the end cover 23. The air outlet holes 12 blow away the glue liquid, leaving a spiral glue path on the inner wall of the molding paper.

[0060] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
