技术领域technical field
本发明属于油箱密封技术领域，具体是一种新型的加油枪加油密封装置。The invention belongs to the technical field of fuel tank sealing, in particular to a novel fueling sealing device for a fueling gun.
背景技术Background technique
通常汽车在进行加油时，加油枪出油管的直径远小于汽车油箱口，能够伸入到汽车的油箱内实现汽油或柴油的添加。现有的加油枪壳体的前端都会设置一个喇叭状的回收罩(可以由橡胶制成)，回收罩罩盖汽车的油箱口避免油气泄露。但是在加油过程中工作人员不会全程手握加油枪，导致回收罩与汽车油箱口不能全程处于紧贴合状态，因而造成油气的大量泄漏。泄露的油气不仅浪费能源，而且污染空气，因此亟需一种可以固定在加油枪上的密封装置来解决这一技术问题。Usually when the car is refueling, the diameter of the oil outlet pipe of the refueling gun is much smaller than the fuel tank port of the car, and can be inserted into the fuel tank of the car to add gasoline or diesel oil. The front end of existing refueling gun housing all can be provided with a trumpet-shaped recovery cover (can be made of rubber), and the fuel tank mouth of recovery cover cover automobile avoids oil-gas leakage. However, during the refueling process, the staff will not hold the refueling gun in their hands throughout the process, resulting in the recovery cover and the automobile fuel tank opening not being in a tight fit state throughout the process, resulting in a large amount of oil and gas leakage. Leaked oil and gas not only wastes energy, but also pollutes the air, so there is an urgent need for a sealing device that can be fixed on the refueling gun to solve this technical problem.
发明内容Contents of the invention

According to the present invention, a new type of refueling sealing device for a refueling gun includes a steel shell 3, a rubber elastic film 6, and a spring 7 with an annular inclined section. An annular rubber elastic membrane 6 is fixed on the inner surface; an annular groove 301 is arranged on the inner surface of the steel shell 3, and an annular inclined section spring 7 is arranged between the annular groove 301 and the rubber elastic membrane 6, and the annular inclination Cross-section spring 7; the annular inclined cross-section spring 7 exerts force to make the middle part of the rubber elastic membrane 6 protrude.
本发明提出的密封装置，结构简单，方便实用，在加油过程中能使加油枪牢牢扣紧在油箱口上，不但能够防止加油枪滑落，而且能够解决加油过程中油气泄露造成的资源浪费、空气污染的问题。The sealing device proposed by the present invention has a simple structure, is convenient and practical, and can firmly fasten the fueling gun on the fuel tank port during the refueling process, which can not only prevent the fueling gun from slipping, but also solve the waste of resources and air pollution caused by oil and gas leakage during the refueling process. pollution problem.

下面通过具体实施例并结合附图对本发明做进一步的详细描述。The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
请参阅图1，一种新型的加油枪加油密封装置，包括钢壳3、橡胶弹力膜6、环形倾斜截面弹簧7，钢壳3通过紧固件Ⅱ4安装在加油枪5壳体的前端并环绕出油管8，由于汽车的油箱口通常为圆形，因而将钢壳3设为圆环形。该钢壳3的内圆面上设有环形的橡胶弹力膜6，橡胶弹力膜6的两端通过紧固件Ⅰ2与钢壳3固接。所述钢壳3与橡胶弹力膜6之间安置有环形倾斜截面弹簧7，钢壳3的内圆面设有环形槽301，环形倾斜截面弹簧7抵接该环形槽301。环形槽301为弹簧提供施力点，确保环形倾斜截面弹簧7 只能沿径向施力，使橡胶弹力膜6中部凸起。Please refer to Fig. 1, a new type of sealing device for refueling gun, including steel shell 3, rubber elastic film 6, annular inclined section spring 7, steel shell 3 is installed on the front end of the shell of refueling gun 5 through fastener II 4 and surrounds it Oil outlet pipe 8, because the fuel tank mouth of automobile is generally circular, thereby steel shell 3 is made as circular ring. An annular rubber elastic film 6 is arranged on the inner surface of the steel shell 3 , and the two ends of the rubber elastic film 6 are fixedly connected to the steel shell 3 by fasteners I2 . An annular oblique section spring 7 is placed between the steel shell 3 and the rubber elastic membrane 6 . The inner surface of the steel shell 3 is provided with an annular groove 301 , and the annular oblique section spring 7 abuts against the annular groove 301 . The annular groove 301 provides a force application point for the spring to ensure that the annular inclined section spring 7 can only apply force in the radial direction, so that the middle part of the rubber elastic membrane 6 protrudes.
紧固件Ⅰ2、紧固件Ⅱ4可为螺钉或螺栓，本发明不限制其种类。The fasteners I2 and II4 can be screws or bolts, and the present invention does not limit their types.
加油时，加油枪的出油管插入油箱口后，对钢壳3施加向下的力，油箱口翻边挤压环形倾斜截面弹簧7，弹簧下滑至油箱口翻边下方后自行沿径向恢复，借助橡胶弹力膜6中部的凸起密封装置向下卡住油箱口，在加油的过程中无论工作人员是否手持加油枪，借助弹簧的径向力确保橡胶弹力膜6与油箱口1全程紧贴，避免油气泄露。加油完成后，对钢壳3施加向上的力，油箱口翻边挤压环形倾斜截面弹簧7，弹簧上滑至油箱口翻边上方后自行沿径向恢复，密封装置随加油枪一起拔出。When refueling, after the oil outlet pipe of the refueling gun is inserted into the fuel tank port, a downward force is applied to the steel shell 3, and the flange of the fuel tank port squeezes the annular inclined section spring 7, and the spring slides down to the bottom of the fuel tank port flange and recovers radially by itself. With the help of the raised sealing device in the middle of the rubber elastic film 6, the fuel tank port is blocked downward. During the refueling process, regardless of whether the staff is holding the refueling gun or not, the radial force of the spring is used to ensure that the rubber elastic film 6 is in close contact with the fuel tank port 1 throughout the process. Avoid oil and gas leakage. After refueling is completed, an upward force is applied to the steel shell 3, and the flange of the fuel tank mouth squeezes the annular inclined section spring 7. The spring slides up to the top of the flange of the fuel tank mouth and recovers radially by itself, and the sealing device is pulled out together with the refueling gun.
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。本领域技术人员在本发明的基础上做各种各样的修改或补充或采用类似的方式替代，只要不偏离本发明的结构或者超越本权利要求书所定义的范围，均应属于本发明的保护范畴。The above describes the technical principles of the present invention in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present invention, and cannot be construed as limiting the protection scope of the present invention in any way. Those skilled in the art make various modifications or supplements on the basis of the present invention or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, all shall belong to the scope of the present invention Protection category.
