Example (b):
as shown in fig. 1-4, the utility model provides a fuel tank cap sealing structure, which is used in cooperation with a fuel filling pipe 1. The fuel tank cap 2 includes a cap body 21 and a connector 22. The lid body 21 is provided with a tube insertion opening 23 into which the filler pipe 1 is inserted. After the filler pipe 1 is inserted into the spigot 23, the filler pipe 1 is fixed to the spigot 23. The connection head 22 is arranged inside the cannula opening 23. The connector 22 is configured to mate with the filler tube 1 such that when the filler tube 1 is inserted into the spigot 23, the filler tube 1 is connected to the connector 22. The connection head 22 can swing following the filler pipe 1.
Specifically, the connector 22 is a connecting pipe disposed inside the socket 23. After the oil filling pipe 1 is inserted into the spigot 23, the pipe orifice of the oil filling pipe 1 is butted and communicated with the pipe orifice of the connector 22, so that fuel oil in the oil filling pipe 1 enters the oil tank through the connector 22. The open end of the connection head 22 is a connection end, and the connection end is connected to the cover body 21 through a hose 221 in order to enable the connection end of the connection head 22 to swing following the filler pipe 1. In practice, the hose 221 may be selected from bellows.
The connection head 22 is provided with an urging spring 222. The urging spring 222 is sleeved on the connector 22, so that when the filler pipe 1 is inserted into the nozzle 23, the connector 22 urges the filler pipe 1.
The utility model discloses a when fuel tank cap seal structure used, will add oil pipe 1 and insert in the mouth of pipe 23 and make and add oil pipe 1 and fuel tank cap 2 and couple together. At this time, the nozzle of the filler pipe 1 is tightly coupled to the coupling head 22. When the filler pipe 1 is shaken relative to the tank cap 2, the connector 22 swings following the filler pipe 1, so that the filler pipe 1 and the connector 22 are always kept in tight connection.
The oil tank cover sealing structure can effectively prevent the oil filling pipe 1 and the connecting head 22 from being separated from each other due to vibration, and further ensure the connection stability. The biasing spring 222 keeps the connection end and the open end of the filler pipe 1 in tight contact with each other.
In this embodiment, the connection end is provided with an inner ring 223 and an outer ring 224. A gap is provided between the inner ring 223 and the outer ring 224 to accommodate the tube wall of the filler tube 1.
After the filler tube 1 is inserted into the spigot 23, the inner ring 223 is received inside the filler tube 1 and abuts the inner wall of the filler tube 1. Meanwhile, the outer ring 224 wraps around the open end of the filler tube 1 and abuts against the outer wall of the filler tube 1. That is, the inner ring 223 and the outer ring 224 confine the filler pipe 1. This allows the filler tube 1 to swing without the filler tube 1 sliding radially relative to the connection end, thereby ensuring a good connection between the connection head 22 and the filler tube 1.
In this embodiment, the inner ring 223 and the outer ring 224 are combined into a groove-shaped receiving groove. The groove bottom of the containing groove is provided with a sealing ring 225. The sealing ring 225 can better ensure the connection tightness and avoid leakage.
In this embodiment, the bottom of the accommodating groove is provided with an oil passing hole 226 penetrating the inner ring 223. The oil passing hole 226 communicates the inside of the connector 22 with the bottom of the receiving groove. When the filler pipe 1 is pulled out, a part of fuel oil is inevitably left. The fuel falls into the containing groove and is collected. The fuel oil in the accommodating groove passes through the oil passing hole 226 to enter the interior of the connector 22, and then enters the oil tank.
In this embodiment, the length of the inner ring 223 in the length direction of the filler pipe 1 is 2 to 5 cm. This length makes when adding oil pipe 1 along radial skew, the cooperation position of inner ring 223 and adding oil pipe 1 pipe wall can effectually drive the link and follow adding oil pipe 1 skew. Thereby ensuring that the two always keep better connection.
In this embodiment, the fuel tank cap 2 is further provided with a fixing member 24. The fixing assembly 24 is provided with 4 sets. The 4 sets of fixation assemblies 24 are evenly distributed along the circumference of the cannula port 23. The fixing assembly 24 includes a jack 241 and a jack spring 242. The ejector rod 241 is disposed in the radial direction of the cannula port 23. The push rod 241 can be extended and retracted inside the fuel tank cap 2, so that when the filler pipe 1 is inserted into the filler pipe opening 23, the push rod 241 can push against the outer wall of the filler pipe 1. The other end of the push rod 241 is accommodated inside the fuel tank cap 2.
The pushing spring 242 is accommodated in the fuel tank cap 2, and the pushing spring 242 is disposed at one end of the fuel tank cap 2 in a manner of being engaged with the push rod 241. Ejector spring 242 is used to push ejector rod 241 into cannula port 23.
In use, the filler tube 1 is inserted into the fuel cap 2 through the tube insertion opening 23. In the plugging process, the oil filling pipe 1 is gradually abutted to the ejector rod 241. The push rod 241 is gradually pushed by the filler pipe 1 as the filler pipe 1 is gradually inserted and pushed back to the inside of the fuel tank cap 2. At this time, the push rods 241 push the filler tube 1 tightly from all around under the action of the push springs 242, so as to prevent the filler tube 1 from falling off relative to the fuel tank cap 2.
In this embodiment, a guide wheel 243 is disposed at one end of the top bar 241 extending into the cannula opening 23. When the filler tube 1 is inserted into the spigot 23, the guide wheel 243 rolls along the outer wall of the filler tube 1. The guide wheel 243 is arranged, so that in the process of inserting and pulling out the oil filling pipe 1, rolling friction exists between the end head of the ejector rod 241 and the oil filling pipe 1, the oil filling pipe 1 can be conveniently inserted and pulled out, and the abrasion of the ejector rod 241 to the oil filling pipe 1 is reduced.
In this embodiment, the guide wheel 243 includes a rolling surface and two side surfaces on both sides of the rolling surface. One side surface of the guide wheel 243 is uniformly provided with a plurality of ratchet teeth 2431 along the circumferential direction of the guide wheel 243. The tank cap 2 is provided with a pawl 25 in cooperation with the ratchet teeth 2431. With the ratchet teeth 2431 engaged with the pawls 25, the guide wheel 243 can only rotate in one direction. In practical arrangement, when the oil filling pipe 1 is inserted, the oil filling pipe 1 can drive the guide wheel 243 to rotate, so that the oil filling pipe 1 can be inserted more smoothly. When the filler tube 1 is pulled out, the pawl 25 blocks the guide wheel 243 so that the guide wheel 243 cannot rotate. This makes it difficult to directly pull out the filler pipe 1, and makes the connection of the filler pipe 1 to the tank cap 2 more stable. If the fuel filler tube 1 needs to be pulled out, the fuel filler tube 1 needs to be rotated by a certain angle, so that the guide wheel 243 is driven by the fuel filler tube 1 to deflect to separate the ratchet teeth 2431 and the pawl 25. At the moment, the oil filling pipe 1 can be conveniently pulled out.
The top bar 241 is further provided with a biasing spring 2432. A hold-down spring 2432 is located on the side of the guide wheel 243 remote from the ratchet teeth 2431 to engage the ratchet teeth 2431 with the pawl 25. The resisting spring 2432 can well ensure that the ratchet teeth 2431 and the pawl 25 can be meshed again after being separated, and further the use stability is ensured.
In this embodiment, each guide wheel 243 is cooperatively provided with a ratchet tooth 2431, a biasing spring 2432, and a pawl 25. The ratchet teeth 2431 of the plurality of guide wheels 243 are all located on the same side. This allows the plurality of pawls 25 and ratchet teeth 2431 to simultaneously disengage when the filler tube 1 is rotated, facilitating the removal of the filler tube 1.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
