[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0034] like Figures 1 to 7 As shown, an oil pipe joint provided by the utility model includes a butt joint 100 and a butt sleeve 200. In a separated state, the butt joint 100 and the butt sleeve 200 are both in a sealed state. When the butt joint 100 is inserted into the butt sleeve 200, the butt joint 100 and the butt sleeve 200 are simultaneously unsealed to achieve mutual connection between pipelines and circulation of oil.

[0035] The docking joint 100 includes a first oil passage 101 opened along its axial direction, a first sealing member 102 movably disposed in the first oil passage 101 , and a first elastic member 103 that applies pressure to the first sealing member 102 to seal the first oil passage 101 .

[0036] Specifically, the docking joint 100 is tubular, the first oil channel 101 penetrates the docking joint 100 axially, the first elastic member 103 is in a compressed state, and the first sealing member 102 seals the first oil channel 101 under the extrusion of the first elastic member 103. When the first sealing member 102 is subjected to external pressure and moves toward the first elastic member 103 to further compress the first elastic member 103, the first oil channel 101 is opened.

[0037] Further, the first sealing member 102 includes a sealing portion 102a located in the first oil passage 101, and a resisting portion 102b perpendicular to the sealing portion 102a, the resisting portion 102b and the first elastic member 103 are respectively arranged on both sides of the sealing portion 102a along the extending direction of the first oil passage 101, and at least part of the resisting portion 102b protrudes out of the first oil passage 101. The sealing portion 102a is used to seal the first oil passage 101, and the resisting portion 102b is used to resist against the second sealing member 202 in the docking sleeve 200, so that when the docking head 100 is inserted into the docking sleeve 200, the resisting portion 102b exposed outside the first oil passage 101 and the second sealing member 202 are pressed against each other, thereby opening the first oil passage 101 and the second oil passage 201 in the docking sleeve 200.

[0038] The first sealing member 102 further includes a connecting column 102c perpendicular to the sealing portion 102a, the connecting column 102c is located on the side where the first elastic member 103 is located, and the first elastic member 103 is a spring, which is sleeved on the connecting column 102c. The connecting column 102c is used to guide the first elastic member 103 to prevent the first elastic member 103 from tilting or twisting during the compression process, resulting in uneven pressure on the sealing portion 102a, and failure to effectively seal the first oil passage 101.

[0039] Furthermore, the docking joint 100 also includes a limiting portion 104 located in the first oil channel 101, the first elastic member 103 is located between the limiting portion 104 and the first sealing member 102, one end of the first elastic member 103 is fixed on the limiting portion 104, and the other end is abutted against the first sealing member 102 to apply pressure to the first sealing member 102 to seal the first oil channel 101.

[0040] In this embodiment, the limiting portion 104 is an inner cylinder threadedly connected to the first oil channel 101. By rotating the inner cylinder, the distance between the inner cylinder and the first sealing member 102 can be adjusted, thereby adjusting the compression amount of the first elastic member 103, ensuring that the pressure applied by the first elastic member 103 to the first sealing member 102 is sufficient to seal the first oil channel 101, while also facilitating the replacement of the first elastic member 103.

[0041] Reference Figure 3 In one embodiment, the first oil passage 101 includes a first oil section 101b and a second oil section 101c, the sealing portion 102a is located in the first oil passage 101b, and the radius of the sealing portion 102a is smaller than the inner diameter of the first oil section 101b and larger than the inner diameter of the second oil section 101c, and the radius of the supporting portion 102b is smaller than the inner diameter of the second oil section 101c.

[0042] Since the inner diameter of the first oil section 101b is larger than the inner diameter of the second oil section 101c, a step portion is formed at the connection position of the first oil section 101b and the second oil section 101c. The sealing portion 102a is pressed against the step portion under the pressure of the first elastic member 103, and since the radius of the sealing portion 102a is larger than the inner diameter of the second oil section 101c, the sealing portion 102a isolates the communication between the first oil section 101b and the second oil section 101c, thereby sealing the first oil passage 101. The pressing portion 102b extends outward from the sealing portion 102a along the second oil section 101c, and the end of the pressing portion 102b away from the sealing portion 102a is located outside the second oil section 101c to be pressed against the second sealing member 202.

[0043] When the docking joint 100 is inserted into the docking sleeve 200, the abutting portion 102b is pressed against the second sealing member 202, pushing the sealing portion 102a to move in a direction away from the second oil section 101c, and the first elastic member 103 is further compressed, the sealing portion 102a is separated from the step portion, the first oil section 101b and the second oil section 101c are connected to each other, and the oil can flow into the second oil section 101c from the gap between the first oil section 101b and the sealing portion 102a. Since the radius of the abutting portion 102b is smaller than the inner diameter of the second oil section 101c, the oil can flow out of the second oil section 101c, and the first oil passage 101 is opened.

[0044] Reference Figure 4 In another embodiment, a sealing ring 101a is provided in the first oil passage 101, and the sealing ring 101a is located on the side of the sealing portion 101a away from the first elastic member 103, the radius of the sealing portion 102a is smaller than the inner diameter of the first oil passage 101 and larger than the inner diameter of the sealing ring 101a, and the radius of the supporting portion 102b is smaller than the inner diameter of the sealing ring 101a.

[0045] Under the pressure of the first elastic member 103 , the sealing portion 102a is pressed against the sealing ring 101a , and because the radius of the sealing portion 102a is greater than the inner diameter of the sealing ring 101a , the sealing portion 102a and the sealing ring 101a together form a sealing plate to seal the first oil passage 101 .

[0046] When the docking joint 100 is inserted into the docking sleeve 200, the supporting portion 102b is pressed against the second sealing member 202, pushing the sealing portion 102a to move toward the first elastic member 103. The first elastic member 103 is further compressed, the sealing portion 102a and the sealing ring 101a are separated, and the first oil passage 101 is opened.

[0047] The docking sleeve 200 includes a second oil passage 201 located therein, a second sealing member 202 movably disposed in the second oil passage 201 , and a second elastic member 203 that applies pressure to the second sealing member 202 to seal the second oil passage 201 .

[0048] The second oil passage 201 axially penetrates the docking sleeve 200, the second elastic member 203 is in a compressed state, and the second sealing member 202 seals the second oil passage 201 under the pressure of the second elastic member 203. When the second sealing member 202 is subjected to external pressure and moves toward the second elastic member 203 to further compress the second elastic member 203, the second oil passage 201 opens.

[0049] Furthermore, the second sealing member 202 has a protrusion 202a for pressing against the first sealing member 102. The protrusion 202a and the second elastic member 203 are respectively arranged on both sides of the second sealing member 202 along the extension direction of the second oil passage 201. The radius of the protrusion 202a is smaller than the inner diameter of the first oil passage 101. In this way, when the docking joint 100 is inserted into the docking sleeve 200, the protrusion 202a can enter the first oil passage 101 to press against the first sealing member 102.

[0050] Of course, only one of the abutting portion 102 b and the protruding portion 202 a may be provided, as long as the mutual extrusion between the first sealing member 102 and the second sealing member 202 can be achieved.

[0051] Furthermore, the docking sleeve 200 further includes a docking head 204 at its end, and the second elastic member 203 is located between the connecting head 204 and the second sealing member 202. One end of the second elastic member 203 is fixed to the connecting head 204, and the other end is pressed against the second sealing member 202 to press the second sealing member 202 to seal the second oil passage 201.

[0052] Reference Figure 5 In one embodiment, the second oil passage 201 includes a third oil section 201b and a fourth oil section 201c, the second seal 202 is located in the fourth oil section 201c, and the radius of the second seal 202 is larger than the inner diameter of the third oil section 201b and smaller than the inner diameter of the fourth oil section 201c.

[0053] Since the inner diameter of the fourth oil section 201c is larger than that of the third oil section 201b, a step portion is formed at the connection position between the third oil section 201b and the fourth oil section 201c, and the second sealing member 202 is pressed against the step portion by the second elastic member 203. Since the radius of the second sealing member 202 is larger than the inner diameter of the third oil section 201b, the sealing portion 102a isolates the third oil section 201b from the communication with the fourth oil section 201c, thereby sealing the second oil passage 201.

[0054] When the docking head 100 is inserted into the docking tube 200, the protrusion 202a is pressed against the first sealing member 102, pushing the second sealing member 202 to move toward the connecting head 204, and the second elastic member 203 is further compressed, so that the second sealing member 202 is separated from the step portion, and the third oil section 201b and the fourth oil section 201c are connected to each other, and the oil can flow from the third oil section 201b into the fourth oil section 201c, and the second oil passage 201 is opened.

[0055] Reference Figure 6 In another embodiment, a limiting ring 201a is provided in the second oil passage 201, and a radius of the second sealing member 202 is smaller than an inner diameter of the second oil passage 201 and larger than an inner diameter of the limiting ring 201a.

[0056] Under the pressure of the second elastic member 203, the second sealing member 202 is pressed against the limiting ring 201a, and because the radius of the second sealing member 202 is larger than the inner diameter of the limiting ring 201a, the second sealing member 202 and the limiting ring 201a together form a sealing plate to seal the second oil channel 201.

[0057] When the docking head 100 is inserted into the docking tube 200, the protrusion 202a is pressed against the first sealing member 102, pushing the second sealing member 202 to move toward the connecting head 204, and the second elastic member 203 is further compressed, so that the second sealing member 202 and the limiting ring 201a are separated, and the second oil passage 201 is opened.

[0058] It should be noted that the inner diameter of the docking sleeve 200 is matched with the outer diameter of the docking head 100, so that when the docking head 100 is inserted into the docking sleeve 200, the oil will not flow out from between the docking head 100 and the docking sleeve 200. Preferably, the outer wall of the docking head 100 and / or the inner wall of the docking sleeve 200 are provided with a sealing ring to further increase the sealing between the two.

[0059] Furthermore, a first limiting block 105 is disposed on an outer wall of the docking head 100 , and a second limiting block 205 matched with the first limiting block 105 is disposed on an inner wall of the docking sleeve 200 .

[0060] Specifically, two groups of the first limit blocks 105 are arranged at intervals along the outer wall of the docking head 100, and two groups of the second limit blocks 205 are arranged at intervals along the inner wall of the docking tube 200. When the docking head 100 is inserted into the docking tube 200, the first limit blocks 105 are inserted from the gap between the two groups of the second limit blocks 205, the first sealing member 102 and the second sealing member 202 are pressed against each other and move in opposite directions, the first elastic member 103 and the second elastic member 203 are further compressed, the first oil passage 201 and the second oil passage 202 are opened and connected to each other, and then the docking head 100 is rotated so that the first limit block 105 is directly opposite to the second limit block 205, and the top of the second limit block 105 is abutted against the bottom of the second limit block 205, thereby completing the docking of the docking head 100 and the docking tube 200 and maintaining the mutual flow of the oil passages therebetween.

[0061] Reference Figure 8 The utility model also provides a refrigerator, comprising the above-mentioned oil pipe joint and a box body 300; a plurality of hydraulic feet 400 arranged at intervals at the bottom of the box body 300; an oil pipe 500 connecting the plurality of hydraulic feet 400, the oil pipe 500 including an oil filling port located at the front side of the box body 300; an oiler 600; one of the docking head 100 and the docking tube 200 is connected to the oil filling port, and the other is connected to the oiler 600.

[0062] The hydraulic foot 400 is used to support the box 300, and the oiler 600 is used to fill the hydraulic foot 400 with oil to lift the box 300 when the refrigerator needs it. The docking sleeve 200 is connected to the oil filling port. When the oiler is not needed, the docking sleeve 200 remains sealed to prevent the oil in the hydraulic foot 400 from flowing out of the oil filling port. The docking head 100 is connected to the oiler 600 and keeps the oiler 600 sealed.

[0063] When oil injection is required, the docking joint 100 on the oil injector 600 is inserted into the docking sleeve 200 at the oil injection port, the docking joint 100 and the docking sleeve 200 are unsealed and connected to each other, so that oil is injected into the hydraulic foot 400 through the oil injector 600. After the oil injection is completed, the docking joint 100 is pulled out, and the docking joint 100 and the docking sleeve 200 are re-sealed, which is convenient and quick and can effectively prevent oil leakage.

[0064] Furthermore, the number of the hydraulic feet 400 is two groups and both are located at the rear side of the box body 100. The oil pipe 500 includes an oil filling pipe 501, a straight pipe 502 and a U-shaped pipe 503 connecting the two hydraulic feet 400. One end of the oil filling pipe 501 is connected to the U-shaped pipe 503 through a tee, and the other end is connected to the docking tube 200. The oil between the two hydraulic feet 400 is connected through the straight pipe 502, and oil is filled into the two hydraulic feet 400 through the oil filling pipe 501 and the U-shaped pipe 503, and the oil filling adjustment can be completed at the front side of the box body 100.

[0065] In summary, the docking joint 100 and the docking sleeve 200 of the utility model are both sealed in a separated state. When the docking joint 100 is inserted into the docking sleeve 200, the docking joint 100 and the docking sleeve 200 are simultaneously unsealed to achieve mutual connection between pipelines and circulation of oil.
