The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1

[0033] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a portable hydraulic equipment oil filling device, the device includes a box 100, a connecting pipe 200 and a hose 300;

[0034] The box body 100 includes a box shell 101 and a bottom plate 102. The box shell 101 is installed on the top of the bottom plate 102 by screws. A placement cavity 103 is provided at the top of the box shell 101. Side panels 104 are fixedly connected to both sides of the box shell 101. A battery is provided inside the placement cavity 103.

[0035] Specifically, a vacuum pump 101a is disposed inside the housing 101, and the vacuum pump 101a is mounted on the top of the bottom plate 102 by bolts, and a battery placed inside the cavity 103 is used to provide power to the vacuum pump 101a.

[0036] Furthermore, a top plate 103 a is mounted on the top of the box shell 101 by screws, and a handle 103 b is mounted on the top of the top plate 103 a by screws. The top plate 103 a is located at the top of the placement cavity 103 .

[0037] Furthermore, the connecting pipes 200 are provided in two groups, and the two groups of connecting pipes 200 are provided inside the box shell 101, and are connected to the output end and the input end of the vacuum pump 101a through threads respectively;

[0038] The connecting tube 200 has a liquid passage trough 201 therein, an annular cavity 202 therein, a first spring 203 therein, a sealing member 204 therein, and a self-locking member 205 therein.

[0039] Preferably, one end of the hose 300 is fixedly connected to a handle 301 , and one end of the handle 301 is fixedly connected to a connector 302 . A groove 303 is provided on the outer side of the connector 302 , and the connector 302 is connected to the hose 300 through the inside of the handle 301 .

[0040] When in use, firstly, the connecting pipe 200 is connected to the vacuum pump 101a inside the box shell 101 through threads, and then the end of the hose 300 is inserted into the other end of the connecting pipe 200, and the hose is placed in a designated position.

[0041] After the vacuum pump 101a is started, the hydraulic oil can be pumped into the vacuum pump 101a through one side hose 300, and then the oil extraction and injection work can be realized through another set of hoses 300.

[0042] In summary, by using the hose 300 and the vacuum pump 101a, it is possible to flexibly operate in a small and complex space, directly reach the hydraulic oil tank to take oil or fill oil. At the same time, compared with the traditional method of taking oil and filling oil using a needle tube and a funnel, the overall work efficiency is more efficient.

[0043] Example 2

[0044] Reference Figures 1 to 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the sealing member 204 includes a sealing plate 204a slidably connected to the inside of the connecting pipe 200, a side groove 204b opened at one end of the sealing plate 204a, and a second spring 204c fixedly connected to one end of the sealing plate 204a, a guide block 204d is fixedly connected to the outer side of the sealing plate 204a, and the other end of the second spring 204c is connected to the inside of the connecting pipe 200.

[0045] Furthermore, the self-locking member 205 includes an inner ring 205a disposed inside the annular cavity 202, a tapered groove 205b formed on the inner wall of the inner ring 205a, and a guide groove 205c formed on the inner wall of the inner ring 205a. A shift block 205d is fixedly connected to the outer side of the inner ring 205a.

[0046] Furthermore, the shifting block 205d is located inside the main groove 200a and the secondary groove 200b, and the guide block 204d is located inside the guide groove 205c.

[0047] It should be noted that a sphere 202a is disposed inside the annular cavity 202, and the sphere 202a is located inside the conical groove 205b.

[0048] By holding the handle 301 at one end of the hose 300 and inserting the connector 302 into the interior of the connecting tube 200, the connector 302 will squeeze the ball 202a during the plugging process, and cooperate with the design of the tapered groove 205b to drive the inner ring 205a to squeeze the first spring 203 until the connector 302 is completely inserted into the interior of the connecting tube 200. At this time, the elasticity of the first spring 203 drives the inner ring 205a to squeeze the ball 202a, causing the ball 202a to be stuck in the groove 303, thereby completing the installation of the connecting tube 200 and the hose 300.

[0049] When the joint 302 is inserted into the connecting pipe 200 and the ball 202 a and the groove 303 are misaligned, the ball 202 a and the groove 303 can be engaged by simply rotating the joint 302 .

[0050] When the vacuum pump 101a is started, the oil will flow from the hose 300 at the input end of the vacuum pump 101a into the connecting pipe 200 at the input end of the vacuum pump 101a. Then, the sealing plate 204a will be squeezed by the oil, and the side groove 204b on the outside of the sealing plate 204a will be connected to the liquid groove 201, so that the oil can flow.

[0051] The connecting pipe 200 flowing to the output end of the vacuum pump 101a will squeeze the sealing plate 204a and the round rod protruding from its center to displace the oil, thereby promoting the oil circulation and achieving the oil extraction and injection work.

[0052] In summary, the fixing method of the joint 302 and the connecting pipe 200 makes the installation of the whole device more convenient, ensuring that the personnel can operate the whole device quickly when carrying or using the device. At the same time, when the connecting pipe 200 is not connected to the hose 300 or the connecting hose 300 does not start the vacuum pump 101a, the connecting pipe 200 is sealed by the sealing plate 204a, which can minimize the impurities entering the vacuum pump during the carrying process of the device and ensure the purity of the hydraulic oil when taking and filling the oil.

[0053] Example 3

[0054] Reference Figures 1 to 9 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that a main groove 200a is opened on the outer side of the connecting pipe 200, a secondary groove 200b is opened on the outer side of the connecting pipe 200, and one end of the main groove 200a is connected to the secondary groove 200b.

[0055] When the vacuum pump 101a is started to take out the oil, the sealing plate 204a slides under the push of the oil. The sliding sealing plate 204a drives the inner ring 205a to rotate under the cooperation of the guide block 204d and the guide groove 205c, so that the shifting block 205d outside the inner ring 205a is engaged in the secondary groove 200b. At this time, the inner ring 205a cannot slide due to the shifting block 205d, thereby making the ball 202a unable to move and firmly engaged in the groove 303. It is ensured that the equipment cannot be disassembled during the process of taking out the oil, that is, it can ensure that the process of taking out the oil can avoid unnecessary accidents caused by accidental touch by personnel, and personnel can also judge the working status of the equipment by observing the specific position of the shifting block 205d.

[0056] When an emergency occurs, personnel can rotate the dial block 205d to the inside of the main groove 200a, and then pull the hose 300 to forcibly disassemble the equipment, ensuring that the equipment can cope with various complex situations and effectively improving the applicability of the equipment.

[0057] In summary, the device utilizes the convenient cooperation between the hose 300 and the vacuum pump 101a, and can easily perform operations in narrow and complex spaces, and directly perform precise oil extraction or oil injection operations on the hydraulic oil tank. The hose 300 and the vacuum pump 101a are quickly plugged in and fixed, which simplifies the installation process and enables staff to quickly deploy the equipment. During the oil extraction and injection operation, the equipment design automatically switches to a non-detachable state, which not only avoids accidents that may be caused by misoperation, but also intuitively shows the operator the working status of the equipment through the position change of the dial block 205d. In addition, in the face of emergency situations, the equipment supports rapid disassembly through simple operations, ensuring the flexibility of application in various emergency or complex environments, thereby significantly improving the practicality and safety of the equipment.
