During the final assembly of an automobile, lubricating oil needs to be injected into the transmission before the engine transmission is installed. For gearboxes provided with an elongated tubular filler neck, a special filler nozzle matching its elongated tubular filler neck is required to fill it.

However, the nozzle member used in the liquid filling gun nozzle is not a standard member, and a hollow structure including a flange head, a flange groove, a flange plate, and a nozzle body is generally obtained by a series of machining such as cutting and through-hole machining of a rod material. In addition, since the nozzle member needs to be provided with a seal ring for sealing the flange groove, a higher requirement is placed on the machining accuracy of the connection between the flange head of the nozzle member and the flange and the connection between the filling member and the connection member, which further increases the manufacturing cost.
In addition, since various internal components are provided in the transmission case, the cavity structure is complicated, and oil needs to be filled in a specific direction during oil filling to prevent oil from splashing and flowing back due to collision with the internal components. Therefore, when the nozzle part is manufactured, in addition to forming the internal oil passage by processing the through hole, the tip of the nozzle part is processed to form the tip oil passage such that the tip outlet is inclined, thereby ensuring filling in a specific direction. However, it is difficult to ensure a smooth connection between the internal oil passage formed by the through-hole machining and the tip oil passage formed by machining the tip, which may affect a smooth flow of oil at the time of filling.
Moreover, because the nozzle part is in a slender tubular shape, the joint of the flange of the nozzle part and the nozzle main body is easy to crack along with use, particularly when dynamic filling of gearbox oil is carried out, stress is further concentrated, the risk of cracking and breaking is further increased, and oil overflows to the outside to pollute an engine.

Preferably, the first end portion 131 of the nozzle 130 is flared, and the outer diameter of the flared first end portion 131 is larger than the inner diameter of the constricted portion 122b provided inside the sleeve portion 122, so as to prevent the nozzle 130 from slipping out of the liquid filling gun nozzle 100 due to looseness or the like in the mounted state. Further, it is preferable that the oil filling passage 130b at the second end 132 of the nozzle 130 is smoothly bent at various angles as needed, thereby filling oil in a specific direction in the transmission case, and simultaneously ensuring smooth flow of the oil at the second end 132 of the nozzle 130 without disturbing the flow stream, thereby effectively preventing splash-back of the oil.
Fig. 5(a) to (b) show an example of a specific structure of seal 140 of liquid filling gun nozzle 100. The sealing member 140 is made of brass or nylon, for example, and is deformable by an external force. The sealing member 140 is slidably fitted around the outer circumference of the nozzle 130 in a state where the nozzle 130 is not mounted to the filling part 110 and the connection part 120. Preferably, the inner diameter of the seal 140 is smaller than the outer diameter of the flared first end 131. Further, the seal 140 shown in fig. 5(a) to (b) has a first contact surface 141 and a second contact surface 142, and when the filling member 110 and the connection member 120 are screwed together by the male screw 112m of the boss portion 112 and the female screw 121n of the female frame portion 121 in a state where the seal 140 is fitted around the outer periphery of the nozzle tube 130 and fitted between the filling member 110 and the connection member 120, the first contact surface 141 of the seal 140 contacts the first tapered surface 112x (also referred to as a boss inclined surface 112x) on the boss portion inner side, and the second contact surface 142 contacts the second tapered surface 121y (also referred to as a female frame inclined surface 121y) of the female frame portion, and is deformed by an external force to be fastened to the first end portion 131 of the nozzle tube 130, so that the nozzle tube 130 cannot be moved or rotated, thereby sealing and fixing the nozzle tube 130 to the filling member 110 and the connection member 120.
Next, the procedure of attaching liquid filling gun nozzle 100 will be described with reference to fig. 1(a) to (b).
First, the seal 140 is fitted around the outer periphery of the nozzle 130 and inserted into the sleeve portion 122 of the connection member 120 from the side of the concave frame portion 121 of the connection member 120. Then, the boss portion 112 of the filling member 110 is screw-fastened to the female frame portion 121 of the connection member, whereby the mounting of the liquid filling gun nozzle 100 is completed and a complete oil filling passage is formed in the liquid filling gun nozzle 100.
In the attached state, the first end 131 of the nozzle 130 is received in the counter bore receiving portion 112a of the boss portion 112, the second end 132 protrudes from the sleeve portion 122 of the connection member 120, the first contact surface 141 of the seal member 140 contacts the first tapered surface 112x inside the boss portion, and the second contact surface 142 contacts the second tapered surface 121y of the recessed frame portion, whereby the nozzle 130 is hermetically fixed via the seal member 140. When the oil ejection direction at the second end 132 of the nozzle 130 needs to be adjusted, the nozzle 130 is adjusted by unscrewing the boss portion 112 of the filling member 110 and the concave frame portion 121 of the connection member and rotating the nozzle. Therefore, the liquid filling gun nozzle 100 of the present invention is extremely simple in mounting work, adjustment work, and replacement work, and has high reliability, compared to the conventional liquid filling gun nozzle 200.
Next, a state in which the liquid filling gun nozzle 100 is connected to the filling nozzle 310 of the transmission case 300 will be described with reference to fig. 6.
Fig. 6 is a schematic sectional view showing a state in which the liquid filling gun nozzle 100 according to the embodiment of the present invention is connected to the filling nozzle 310 of the transmission case 300. As shown in fig. 6, in a state where the assembly of the liquid filling gun nozzle 100 is completed, the liquid filling gun nozzle 100 is inserted into the filling nozzle 310 of the transmission case 300 and oil is injected.
Since the downstream end portion 122d of the sleeve portion 122 of the connecting member 120 in the liquid filling gun nozzle 100 is flared, the liquid filling gun nozzle 100 can be easily inserted into the filling nozzle 310.
Further, the gas discharge hole 122a is opened in the side surface of the sleeve portion 122, and when the insertion of the liquid filling gun nozzle 100 is completed, the upper end surface of the filling nozzle 310 is flush with the center line of the gas discharge hole 122a, and the gas discharge passage 310a is formed between the inner peripheral surface of the filling nozzle 310 and the outer peripheral surface of the nozzle tube 130, whereby the gas in the transmission case can be smoothly discharged to the outside through the gas discharge passage 310a and the gas discharge hole 122a as the oil is filled.
Further, since the constricted portion 122b is provided on the inner surface of the sleeve portion 122 at a position upstream of the exhaust hole 122a, and the constricted portion 122b has an inner diameter slightly larger than the outer diameter of the main body portion of the nozzle tube 130 and smaller than the outer diameter of the flared first end portion 131 of the nozzle tube 130, even if the nozzle tube 130 cannot be firmly fixed due to the damage of the seal 140, the nozzle tube 130 can be prevented from slipping down from the liquid filling gun nozzle 100 into the transmission case to cause a production accident. In addition, since the inner diameter of the constricted portion 122b is slightly larger than the outer diameter of the main body portion of the nozzle 130, the swing range of the nozzle 130 by the external force can be effectively restricted, and thus the nozzle 130 can be protected from affecting the sealing performance of the seal member 140.
In addition, in a state where the assembly of the liquid filling gun nozzle 100 is completed, the filling nozzle 310 of the transmission case 300 is disposed between the inner peripheral surface of the sleeve portion 122 of the connection member 120 and the outer peripheral surface of the nozzle tube 130, and a gap a between the outer peripheral surface of the filling nozzle 310 and the inner peripheral surface of the sleeve portion 122 is smaller than a gap B between the inner peripheral surface of the filling nozzle 310 and the outer peripheral surface of the nozzle tube 130. Accordingly, when the liquid filling nozzle 100 receives an external force during the filling process, the external force acts on the sleeve portion 122 of the coupling member 120 and is absorbed by the filling nozzle 310 and the transmission case 300, and deformation and breakage of the elongated nozzle 130 due to the external force acting thereon can be effectively avoided, and the nozzle 130 can be protected more reliably than in the related art.
Further, since the nozzle 130 is directly formed by performing the hole expanding process or the bending process on the seamless steel pipe, the manufacturing cost can be significantly reduced as compared with the conventional art, and the fracture due to the stress concentration can be effectively avoided. Even if the nozzle 130 is damaged, the nozzle 130 can be replaced by simply unscrewing the boss portion 112 of the filling member 110 and the concave frame portion 121 of the connection member, and therefore, the replacement operation of the nozzle 130 is very convenient.
Furthermore, in the liquid filling gun nozzle 100 of the present invention, since the nozzle 130 having a specific ejection direction can be obtained only by bending the seamless steel pipe, it is easier to ensure the smooth connection between the internal passage of the nozzle 130 and the bent passage of the second end 132, and the filling of oil can be made smoother and more stable, compared with the prior art.
In addition, since the sealing member 140 is made of brass, nylon, or other materials that can be deformed by an external force, before being mounted to the filling unit 110 and the connection unit 120, the sealing member 140 is slidably fitted around the outer circumference of the nozzle 130, when the external thread 112m of the boss portion 112 in the filling member 110 is screwed with the internal thread 121n of the concave frame portion 121 in the connection member 120, the first contact surface 141 and the second contact surface 142 of the sealing member 140 are respectively in contact with the boss inclined surface 112x and the recessed frame inclined surface 121y, and is deformed and fastened to the nozzle 130 by an external force, and the nozzle 130 can be firmly and hermetically fixed to the filling member 110 and the connection member 120, so that, compared to the prior art, the requirement for the machining accuracy of the joint between the filling member 110 and the connecting member 120 is greatly reduced, and thus the manufacturing cost of the liquid filling gun nozzle 100 can be further reduced.
The liquid filling gun nozzle 100 according to the embodiment of the present invention has been described above in detail, but the present invention is not limited thereto, and the liquid filling gun nozzle of the present invention may be modified as follows, for example.

In the above embodiment, the male screw 112m is used as the first fastening portion of the filling member 110, the female screw 121n is used as the second fastening portion of the connection member 120, and the filling member 110 and the connection member 120 are fastened together so that the nozzle 130 is hermetically fixed via the seal 140, but the first fastening portion of the filling member 110 and the second fastening portion of the connection member 120 may be fastened together by magnetic attraction, fitting, or the like. The fastening manner of the first fastening portion of the filling member 110 and the second fastening portion of the connection member 120 is not particularly limited as long as the nozzle tube made of seamless steel pipe can be sealed and fixed via the seal member in a state where the first fastening portion provided to the filling member and the second fastening portion provided to the connection member are fastened.
In the above embodiment, the first contact surface 141 of the seal member 140 is brought into contact with the first tapered surface 112x on the inner side of the boss portion of the filling member 110, and the second contact surface 142 is brought into contact with the second tapered surface 121y of the concave frame portion of the connection member 120, deformed by an external force, and fastened to the spout 130. However, the present invention is not limited to this, and the first contact surface and the second contact surface of the sealing member may be configured to be in contact with the filling member and the coupling member, respectively, and to be capable of sealing and fixing the spout, and the contact manner of the sealing member with the filling member and the coupling member is not particularly limited.
In addition, the above description has been given of the case where the liquid filling gun nozzle of the present invention is used for filling the lubricating oil of the transmission, but the present invention is not limited to this case, and the liquid filling gun nozzle of the present invention can be applied to filling of various liquids into all containers having a long and thin tubular filling nozzle, in addition to the filling of the lubricating oil into the transmission.
Further, while the exemplary embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present invention without substantially departing from the spirit and scope of the present invention.
