DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] An external fuel pump with a quick-release plug comprises a pump body 1, one end of which is provided with a plug assembly 2, the plug assembly 2 comprising a main plug 21 connected to the pump body 1, one end of the main plug 21 being connected to a docking joint 22, one end of the docking joint 22 being provided with a plugging groove 23, an oil pipe plug 24 being plugged into the interior of the plugging groove 23, a docking card 25 being fixedly mounted on the surface of the oil pipe plug 24, a locking sleeve 26 being threadedly mounted on the surface of the docking card 25, an adapter 211 matching the locking sleeve 26 being fixedly connected to the top and bottom of the surface of the docking joint 22, a clamping block 29 being fixedly connected to one end of both sides of the docking card 25, and a clamping groove 210 matching the clamping block 29 being provided on both sides of the docking joint 22.

[0026] The specific usage process is as follows: first, the main plug 21 is connected to the pump body 1, the oil pipe plug 24 is plugged into the plug groove 23 on the docking joint 22, and the end of the oil pipe plug 24 away from the docking joint 22 will also be connected to the oil pipe to achieve normal fuel supply. During installation, the user controls the oil pipe plug 24 to align with the plug groove 23 and inserts the end of the oil pipe plug 24 into the plug groove 23. At this time, the oil pipe plug 24 is docked with the docking joint 22. When the oil pipe plug 24 is docked with the docking joint 22, the two extended strip parts at one end of the docking card 25 will also be inserted into the groove formed by the two adapters 211, and the card groove 210 is also located in the groove. As the docking card 25 is inserted into the corresponding groove, the card groove 210 is arranged in the docking joint. The block 29 on the connecting card 25 will also gradually align with the corresponding slot 210. When the strip-shaped portion of the connecting card 25 just enters the groove, it will be stretched outward to a certain range by the connecting head 22. It should be noted that the two strip-shaped portions on the connecting card 25 have a certain toughness and can make corresponding changes when being stretched by the connecting head 22. They also have a certain elasticity. This is a prior art and will not be explained in detail in the text. In this way, when the block 29 is aligned with the corresponding slot 210, the strip-shaped portion will rebound, so that the block 29 will be stuck in the corresponding slot 210, so that the initial positioning of the connecting card 25 and the oil pipe plug 24 can be achieved, and the oil pipe plug 24, the connecting card 25 and the oil pipe can be prevented from moving at will, and the initial positioning can be completed. The user then twists the locking sleeve 26. Because the locking sleeve 26, the docking card 25 and the adapter 211 are threadedly connected, and the diameters of the docking card 25 and the adapter 211 are the same, the locking sleeve 26 and the adapter 211 are also adapted. Therefore, after the locking sleeve 26 is rotated, it will move on the docking card 25 and move along the docking card 25 to the adapter 211, so that the locking sleeve 26 can also be installed on the adapter 211, thereby docking the docking card 25 and the adapter 211 together, and the oil pipe plug 24 and the docking joint 22 can also be docked together. It should be noted that the length of the locking sleeve 26 can also be designed to be lengthened, so that the locking sleeve 26 can cover the adapter 211 and the docking joint at the same time. The locking sleeve 26 is mounted on the connecting card 25 to ensure the integrity of the oil pump after docking. During the process of installing the locking sleeve 26 on the adapter 211, the locking sleeve 26 will shrink and squeeze the two strip parts on the docking card 25, so that the strip parts are more closely attached to the surface of the docking head 22, and will be accurately stuck in the corresponding groove, and will also limit the block 29 from being stuck in the corresponding slot 210. Moreover, under the action of the locking sleeve 26, the block 29 is stuck in the corresponding slot 210 and will not move arbitrarily, thereby improving the firmness of the oil pipe plug 24 after docking with the docking head 22 and the main plug 21, and improving the sealing of the oil pump after being connected to the oil pipe. Moreover, during the disassembly and assembly work, there will be no restrictions on space and other factors, and the oil pump can be quickly removed from the vehicle.Improve the speed of oil pump disassembly and replacement, improve the efficiency of user maintenance work, and provide convenience for users' work.

[0027] Therefore, a threaded connection structure is adopted, and the installation trajectory is consistent with the axis of the pump body, and it can be unlocked and installed by rotating along the axis. In this way, the user's disassembly and assembly work will not be restricted by space and other factors. The oil pump can be quickly removed from the vehicle, which increases the speed of disassembly and replacement of the oil pump, improves the efficiency of the user's maintenance work, and provides convenience for the user's work.

[0028] A baffle plate 27 is sleeved on one side of the surface of the oil pipe plug 24 , and a stopper 28 is fixedly connected to one end of both sides of the docking clamp 25 . Both the baffle plate 27 and the stopper 28 are adapted to the locking sleeve 26 .

[0029] Specifically, the baffle 27 and the block 28 are provided, and both the baffle 27 and the block 28 are used to limit the locking sleeve 26 to prevent the locking sleeve 26 from being separated from the docking clamp 25 during use, ensuring that the docking clamp 25 can be firmly stuck on the docking head 22, providing convenience for users, and also ensuring the stability of the docking between the oil pipe plug 24 and the docking head 22.

[0030] The top and bottom of one end of the pump body 1 are connected with auxiliary plugs 3, and the two auxiliary plugs 3 are distributed above and below the plug assembly 2. The two sides of the surface of the pump body 1 are sleeved with fixed sleeves 4, and the surface of the fixed sleeve 4 is provided with a slide groove 1 5, and the two sides of the inner cavity of the slide groove 1 5 are provided with slide grooves 2 11, and the inner cavities of the slide grooves 2 11 and the slide grooves 1 5 are slidably installed with sliders 6, and one side of the slider 6 is fixedly connected with a pre-installed plate 9 located on the outside of the fixed sleeve 4.

[0031] Specifically, due to the arrangement of the slide groove 1 5 , the slider 6 and the slide groove 2 11 , the oil pump may be difficult to align during installation. In this case, the user can move the pre-installed plate 9 , which will drive the slider 6 to slide in the slide groove 1 5 and the slide groove 2 11 . In this way, the pre-installed plate 9 can be adjusted to any angle within a range of 360 degrees until the user's installation requirements are met, thereby providing convenience for the user's installation work.

[0032] Pre-installation holes 10 are provided on both sides of the top of the pre-installation plate 9 , and both pre-installation holes 10 are oblong holes.

[0033] Specifically, the pre-installation hole 10 is provided on the pre-installation plate 9, so that when the user installs the oil pump, the user can insert the bolt into the pre-installation hole 10 and then install the oil pump on the vehicle, which provides convenience for the user's work.

[0034] A positioning pin 8 is provided through one side of the fixing sleeve 4 , one end of which is inserted into the interior of the slider 6 , and a plurality of positioning holes 7 matching with the positioning pin 8 are provided on one side of the fixing sleeve 4 .

[0035] Specifically, with the arrangement of the positioning socket 7 and the positioning pin 8, after the slider 6 is moved and adjusted to a desired position, the user passes the positioning pin 8 through the positioning socket 7 at the current position, and then inserts it into the slider 6, and finally tightens the slider 6. In this way, the slider 6 can be positioned at the current position, and the pre-installed plate 9 can also be positioned at the current position, providing convenience for the user's work.

[0036] It should be noted that the functions to be implemented by each hardware in the utility model are supported by a large number of mature technologies and belong to the existing technology. The essence of the utility model is to optimize the combination of existing hardware and its connection method for specific application scenarios to meet the adaptation needs in specific application scenarios and solve the problems raised in the background technology (not involving improvements to the software inside the hardware).
