Example 1:

the oil product replacing device shown in fig. 1-4 is used for taking out oil products in external equipment, and comprises a liquid collecting bottle 1 for containing liquid, wherein the same side or two sides of the end surface of the liquid collecting bottle 1 are respectively connected with a vacuum pump 2 and the external equipment; the joint of the liquid collecting bottle 1 and external equipment is provided with a connecting mechanism 3 for installing a pipeline, the connecting mechanism 3 comprises a first bottle mouth 301 fixedly connected with the liquid collecting bottle 1 and a joint 302 detachably connected with the first bottle mouth 301 through threads, an elastic element 303 with a through hole for the pipeline to pass through is arranged in the joint 302, and the aperture size of the elastic element 303 is inversely related to the thread engagement length of the first bottle mouth 301 and the joint 302.

The working principle is as follows:

when in use, firstly, the liquid collecting bottle 1 is communicated with the vacuum pump 2 and an external device (namely a device needing to be replaced with oil product) at the same time, the connecting mechanism 3 between the liquid collecting bottle 1 and the external device is used for ensuring the air-tight connection between the liquid collecting bottle 1 and the external device, concretely, firstly, a pipeline for connecting the liquid collecting bottle 1 and the external device penetrates through the joint 302 and penetrates into the liquid collecting bottle 1 through the first bottle opening 301, then the joint 302 is rotated to ensure that the meshing length of the joint 302 and the thread on the first bottle opening 301 is gradually increased, so that the diameter of the through hole of the elastic element 303 is gradually reduced until the through hole of the elastic element 303 is adapted to the diameter of the pipeline, the surface of the pipeline is in close contact with the elastic element 303, the pipeline is firmly clamped and the air-tight connection between the liquid collecting bottle 1 and the external device is ensured, thereby the vacuum pump 2 is communicated with the external device through the liquid collecting bottle 1, the air in the liquid collecting bottle 1 is pumped by the vacuum pump 2, the liquid collecting bottle 1 is led to pump out the oil in the external equipment.

It is worth explaining, in order to increase the convenience that equipment was changed to the oil in this application, the preferred small-size chargeable type vacuum pump 2 of vacuum pump 2 in this application, and the preferred detachable of vacuum pump 2 installs on collecting bottle 1, makes vacuum pump 2 demountable installation on collecting bottle 1 through set up the installation mechanism that is used for installing fixed vacuum pump 2 specially on collecting bottle 1, can directly pull down when vacuum pump 2 electric quantity exhausts and charge.

Example 2:

this example is further optimized and defined based on example 1.

As shown in fig. 5, the inner wall of the adaptor 302 is provided with an internal thread 3021 corresponding to the first bottle mouth 301, and a table 3022 for mounting the elastic element 303 to form a step is arranged above the internal thread 3021. As shown in fig. 4, the elastic member 303 is a rubber ring. It is worth mentioning that the table 3022 is provided to facilitate mounting of the resilient element 303, since the longer the engagement length of the first bottleneck 301 and the coupling 302 is, the more the elastic member 303 is pressed to the smaller diameter of the through hole, and therefore, in the initial state where the adapter 302 is not yet fitted to the first mouth 301, only a small area of the top or side of the rubber ring is fixedly connected to the inner wall of the adapter 302, for example, by adhesively securing a rubber ring within the fitting 302, the rubber ring has a greater height, a lower edge that is lower than the top edge line of the internal threads 3021, thereby ensuring that during engagement of the internal threads 3021 in the nipple 302 with the threads on the first mouth 301, the elastic member 303 can be simultaneously pressed and deformed by the first bottleneck 301 and the adapter 302, fig. 6 is a schematic view showing the structure of the elastic member 303 after being pressed in the joint 302.

It should be noted that, in the present embodiment, the change of the diameter of the through hole is realized by using the elastic deformation capability of the material of the rubber ring itself, and the correlation between the magnitude of the pressure applied and the diameter change depends on the specific arrangement mode of the rubber ring, for example, when the rubber ring is a solid ring, the degree of the diameter change is relatively small, but the contact area with the pipe is large, so that the rubber ring is suitable for the situation that the diameter difference of the pipes required by each external device is small; when the rubber ring is a ring surrounded by hollow materials, the diameter of the middle through hole is changed to a larger degree due to flattening after the rubber ring is pressed, and the rubber ring is suitable for the condition that the diameter difference of pipelines required by each external device is larger.

The fitting 304 in this embodiment is a part that is specially adapted to fit the pipe and can be connected to the joint 302, so as to further ensure a stable connection between the pipe and the joint 302, and at the same time, the fitting of the fitting to the pipe cannot ensure airtightness due to process reasons, but can add extra support to the pipe when the pipe is connected to the joint 302, thereby ensuring airtightness when the pipe is fitted to the joint 302. When the assembly type liquid collecting bottle is used, the assembly part 304 is sleeved on a pipeline in advance, the pipeline penetrates through the connector 302 and then is inserted into the first bottle neck 301, then the connector 302 is rotated to fix the connector 302 and the first bottle neck 301, the pipeline is initially fixed on the liquid collecting bottle 1, and finally the assembly part 304 is rotated to fix the assembly part 304 on the connector 302 to further fix the pipeline.
