Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of oil unloading devices, specifically an automatic sealed oil unloading device. Background Technology
[0002] The unloading device is mainly used for unloading oil from oil transport equipment. Operators connect the oil transport equipment and the oil storage equipment through the unloading device. When the valve of the oil transport equipment is opened, the oil will flow into the oil storage equipment through the hose, unloading joint and unloading device under its own gravity. This protects the oil during unloading and prevents external objects from contaminating the oil.
[0003] Due to their ease of use, oil unloading devices have been widely adopted. However, in actual use, they still have shortcomings. When connecting the oil unloading connector and the oil unloading device, they are usually connected manually using clips, and the seal is achieved by the cooperation of the clips and grooves. However, relying solely on clips for connection is not stable and cannot achieve automatic sealing. Moreover, the clips are prone to damage, which affects the sealing performance and leads to oil leakage. Therefore, improvements are needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic sealed oil unloading device, comprising an oil unloading pipe, an oil unloading connector movably sleeved inside the middle end of the oil unloading pipe, a rubber flexible ring fixedly installed at the bottom of the inner cavity of the oil unloading pipe, the outer surface of the rubber flexible ring movably sleeved with the inner surface of the inner cavity of the oil unloading pipe, a pressure plate movably installed at the top of the rubber flexible ring, the outer surface of the pressure plate movably sleeved with the inner surface of the inner cavity of the oil unloading pipe, the inner surface of the pressure plate movably sleeved with the outer surface of the oil unloading connector, and round rods fixedly installed around the top of the pressure plate, with a stop fixedly sleeved at the top of the round rods. The plate has a fixed block located below the baffle that is movably sleeved on the top of the outer surface of the round rod. The outer surface of the fixed block is fixedly sleeved with the inner surface of the unloading pipe. A fixed ring is movably sleeved on the outer surface of the round rod. The outer surface of the fixed ring is fixedly sleeved with the inner surface of the unloading pipe. The top end of the fixed ring is fixedly connected to the bottom end of the fixed block. A first spring located outside the round rod is fixedly installed at the bottom end of the fixed ring. The other end of the first spring is fixedly connected to the top end of the pressure plate. A notch is opened on the inner wall of the fixed ring. A protrusion located above the notch is fixedly sleeved on the outer surface of the unloading connector.
[0006] As a preferred embodiment of this utility model, a hose is fixedly sleeved on the top of the outer surface of the oil unloading connector, and an annular plate located between the hose and the oil unloading pipe is fixedly sleeved on the outer surface of the oil unloading connector.
[0007] As a preferred embodiment of this utility model, a positioning rod is fixedly installed on the left side of the bottom end of the ring plate, and a slot is provided inside the positioning rod.
[0008] In a preferred embodiment of this invention, a positioning block is movably sleeved on the outer surface of the positioning rod, the right end of the positioning block is fixedly connected to the outer surface of the oil unloading pipe, and a locking block is movably sleeved on the bottom of the left inner wall of the positioning block, the outer surface of the locking block is movably connected to the outer surface of the positioning rod.
[0009] As a preferred embodiment of this utility model, an extension rod is fixedly installed on the left end of the card block, and the left end of the extension rod passes through the positioning block and extends to the outside of the positioning block and is fixedly sleeved with a circular plate.
[0010] As a preferred embodiment of this utility model, a second spring located outside the extension rod is fixedly installed on the right end of the circular plate, the other end of the second spring is fixedly connected to the left end of the positioning block, and a handle is fixedly installed on the left end of the circular plate.
[0011] As a preferred embodiment of this utility model, a valve is fixedly installed at the bottom end of the oil unloading pipe, and a connecting pipe is fixedly installed at the bottom end of the valve.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a rubber soft ring, a pressure plate, a first spring, a notch, and a protrusion, when the oil unloading connector is pushed, the oil unloading connector will move along the inner surface of the oil unloading pipe with the protrusion. When the protrusion passes through the notch and continues to move towards the pressure plate, the protrusion will generate a pushing force on the pressure plate after contacting it, pushing the pressure plate to move with the round rod and stretching the first spring. This causes the pressure plate to squeeze the rubber soft ring and cause the rubber soft ring to undergo elastic deformation. In this way, the rubber soft ring can achieve automatic sealing of the oil unloading device and improve its sealing effect.
[0014] 2. This utility model, by setting a positioning rod, a slot, a block, a circular plate, and a second spring, will cause the circular plate, along with the extension rod and the block, to move and stretch the second spring when the handle is pulled. Since the size of the block and the slot are the same, when the positioning rod, along with the slot, stops moving along the inner surface of the positioning block, the block will align with the slot. At this time, when the handle is released, the block will be embedded in the slot under the restoring action of the second spring, thereby playing an auxiliary positioning and fixing role for the oil unloading pipe and the oil unloading connector.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6As shown, this utility model provides an automatic sealed oil unloading device, including an oil unloading pipe 1, an oil unloading connector 2 movably sleeved inside the middle end of the oil unloading pipe 1, a rubber flexible ring 3 fixedly installed at the bottom of the inner cavity of the oil unloading pipe 1, the outer surface of the rubber flexible ring 3 movably sleeved with the inner surface of the inner cavity of the oil unloading pipe 1, a pressure plate 4 movably installed at the top of the rubber flexible ring 3, the outer surface of the pressure plate 4 movably sleeved with the inner surface of the inner cavity of the oil unloading pipe 1, the inner surface of the pressure plate 4 movably sleeved with the outer surface of the oil unloading connector 2, and round rods 5 fixedly installed around the top of the pressure plate 4, with baffles 6 fixedly sleeved at the top of the round rods 5, and the outer surface of the round rods 5... The top of the unloading pipe 1 is movably sleeved with a fixing block 7 located below the baffle 6. The outer surface of the fixing block 7 is fixedly sleeved with the inner surface of the unloading pipe 1. The outer surface of the round rod 5 is movably sleeved with a fixing ring 8. The outer surface of the fixing ring 8 is fixedly sleeved with the inner surface of the unloading pipe 1. The top end of the fixing ring 8 is fixedly connected with the bottom end of the fixing block 7. The bottom end of the fixing ring 8 is fixedly installed with a first spring 9 located outside the round rod 5. The other end of the first spring 9 is fixedly connected with the top end of the pressure plate 4. The inner wall of the fixing ring 8 is provided with a notch 10. The outer surface of the unloading connector 2 is fixedly sleeved with a protrusion 11 located above the notch 10.
[0024] When the unloading connector 2 is pushed along the inner surface of the unloading pipe 1, the unloading connector 2, along with the protrusion 11, will pass through the recess 10 and continue to move downwards. When the bottom end of the protrusion 11 contacts the top end of the pressure plate 4, pushing the unloading connector 2 will cause the protrusion 11 to exert a pushing force on the pressure plate 4, which will push the pressure plate 4 and the round rod 5 to move and stretch the first spring 9. As the pressure plate 4 continues to move, the pressure plate 4 will squeeze the rubber soft ring 3, causing the rubber soft ring 3 to deform and squeeze the outer surface of the unloading connector 2. In this way, the rubber soft ring 3 can be used to achieve automatic sealing of the unloading device and improve the sealing effect.
[0025] The top of the outer surface of the oil unloading connector 2 is fixedly sleeved with a hose 12, and the outer surface of the oil unloading connector 2 is fixedly sleeved with a ring plate 13 located between the hose 12 and the oil unloading pipe 1.
[0026] The presence of the hose 12 facilitates connection to the oil outlet of the oil transport equipment, while the ring plate 13 serves as an auxiliary support.
[0027] A positioning rod 14 is fixedly installed on the left side of the bottom end of the ring plate 13, and a slot 15 is opened inside the positioning rod 14.
[0028] The slots 15 are evenly distributed inside the positioning rod 14. The cooperation between the positioning rod 14 and the slots 15 will play a positioning role when the oil unloading pipe 1 and the oil unloading connector 2 are connected.
[0029] The positioning rod 14 is movably sleeved with a positioning block 16. The right end of the positioning block 16 is fixedly connected to the outer surface of the oil unloading pipe 1. The bottom of the left inner wall of the positioning block 16 is movably sleeved with a locking block 17. The outer surface of the locking block 17 is movably connected to the outer surface of the positioning rod 14.
[0030] The size of the card block 17 is the same as the size of the card slot 15, thereby ensuring that the card block 17 can be embedded in the card slot 15.
[0031] The left end of the locking block 17 is fixedly installed with an extension rod 18. The left end of the extension rod 18 passes through the positioning block 16 and extends to the outside of the positioning block 16, and is fixedly sleeved with a circular plate 19.
[0032] When the circular plate 19 moves, it will move along with the locking block 17 via the extension rod 18.
[0033] The circular plate 19 has a second spring 20 fixedly installed on the right end, located outside the extension rod 18. The other end of the second spring 20 is fixedly connected to the left end of the positioning block 16. The circular plate 19 has a handle 21 fixedly installed on the left end.
[0034] When the handle 21 is pulled, the circular plate 19 will move and stretch the second spring 20.
[0035] Among them, a valve 22 is fixedly installed at the bottom end of the oil unloading pipe 1, and a connecting pipe 23 is fixedly installed at the bottom end of the valve 22.
[0036] When valve 22 is opened, the oil output from unloading connector 2 will enter the oil storage device through unloading pipe 1, valve 22 and connecting pipe 23.
[0037] Working principle and usage process of this utility model:
[0038] First, the operator aligns the positioning rod 14 with the inner cavity of the positioning block 16, and then inserts the positioning rod 14 into the positioning block 16, causing the oil unloading connector 2 to move along the inner surface of the oil unloading pipe 1. Then, the operator pulls the handle 21, causing the handle 21 to move along with the circular plate 19 and stretch the second spring 20, so that the circular plate 19 moves along with the locking block 17 through the extension rod 18. Then, the operator continues to push the oil unloading connector 2 until the oil unloading connector 2 and the oil unloading pipe 1 achieve automatic sealing. At this time, the locking groove 15 will align with the locking block 17. Then, the operator releases the handle 21, and under the restoring action of the second spring 20, the locking block 17 will be embedded in the locking groove 15, thereby assisting in the positioning and fixing of the oil unloading pipe 1 and the oil unloading connector 2.
[0039] During the automatic sealing process of the oil unloading pipe 1 and the oil unloading connector 2, the protrusion 11 will move together with the oil unloading connector 2 and pass through the notch 10 to contact the top of the pressure plate 4. At this time, as the protrusion 11 continues to move, the bottom end of the protrusion 11 will generate a pushing force on the top of the pressure plate 4, pushing the pressure plate 4 and the round rod 5 to move towards the rubber soft ring 3 and stretch the first spring 9. As a result, the rubber soft ring 3 will undergo elastic deformation under the action of the pressure plate 4, so that the outer surface of the rubber soft ring 3 and the outer surface of the oil unloading connector 2 are tightly attached. In this way, the automatic sealing of the oil unloading pipe 1 and the oil unloading connector 2 can be achieved by means of the rubber soft ring 3, thereby improving its sealing effect.
