[0019] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0020] As Figures 1 to 4 The utility model discloses an oil injection device for rail joint plate, including the input end can be connected with the oil injection gun's tee bend 1, two output ends of tee bend 1 are connected with first oil injection pipe 2 and second oil injection pipe 3 respectively, the end of first oil injection pipe 2 is connected with first oil injection nozzle 4, the end of second oil injection pipe 3 is connected with the second oil injection nozzle 5 of opposite first oil injection nozzle 4, and the interval of first oil injection nozzle 4 and second oil injection nozzle 5 can be adjusted.

[0021] The input end of tee bend 1 can be provided with a self-locking joint, thereby being connected with the oil injection gun. First oil injection pipe 2 and second oil injection pipe 3 can deliver lubricating oil to respective corresponding oil injection nozzles. First oil injection pipe 2 and second oil injection pipe 3 are preferably made of hard materials such as stainless steel, brass or aluminum alloy, thereby improving stability. First oil injection nozzle 4 is oppositely arranged with second oil injection nozzle 5. When injecting oil into joint plates having symmetrically arranged oil injection holes on both sides, only one oil injection nozzle needs to be aligned with an oil injection hole, so that both oil injection nozzles are on the same axis with the corresponding oil injection holes. At this time, the distance between first oil injection nozzle 4 and second oil injection nozzle 5 is adjusted, so that when one oil injection nozzle is aligned with an oil injection hole, the other oil injection nozzle is inserted into the oil injection hole on the other side.

[0022] Through the oppositely arranged first oil injection nozzle 4 and second oil injection nozzle 5, and the adjustable interval between first oil injection nozzle 4 and second oil injection nozzle 5, the user only needs to align one of the oil injection nozzles with an oil injection hole on one side, and then adjust the interval between the two oil injection nozzles, so that the other oil injection nozzle can be matched with the oil injection hole on the other side. Without directly aligning the oil injection hole that is obstructed by the line of sight, simultaneous oil injection into the oil injection holes on both sides of the joint plate can be realized, thereby improving oil injection efficiency and operation convenience.

[0023] The tee bend 1 is a flexible tee bend 1, and an adjusting mechanism 6 capable of adjusting the interval between second oil injection nozzle 5 and first oil injection nozzle 4 is arranged between first oil injection pipe 2 and second oil injection pipe 3.

[0024] The flexible tee bend 1 can be made of materials such as nitrile rubber. The adjusting mechanism 6 can adjust the distance between first oil injection nozzle 4 and second oil injection nozzle 5, so that when one oil injection nozzle is aligned with an oil injection hole, the other oil injection nozzle can be inserted into the oil injection hole on the other side through the adjusting mechanism 6.

[0025] As Figures 1 to 3As shown, in the first embodiment, when the oil injection device is used, first, the input end of the flexible three-way pipe 1 is connected with the oil injection gun, then the oil injection gun is close to the rail joint plate which needs to be lubricated, the first oil injection nozzle 4 is aligned with and inserted into the oil injection hole on one side, and the insertion of the first oil injection nozzle 4 is ensured to be stable. At this time, the second oil injection nozzle 5 opposite to the first oil injection nozzle 4 is aligned with the oil injection hole on the other side, and the second oil injection nozzle 5 can be inserted into the oil injection hole on the other side by adjusting the distance between the second oil injection nozzle 5 and the first oil injection nozzle 4 through the adjusting mechanism 6. Then the oil injection gun is started, and the lubricating oil will be distributed to the first oil injection pipe 2 and the second oil injection pipe 3 through the flexible three-way pipe 1, and then injected into the oil injection holes on both sides of the joint plate from the first oil injection nozzle 4 and the second oil injection nozzle 5. When the lubricating oil is filled to the required amount, the oil injection gun is turned off. Then the adjusting mechanism 6 is adjusted so that the second oil injection nozzle 5 exits the oil injection hole, and then the first oil injection nozzle 4 is pulled out of the oil injection hole, thereby completing the oil injection of the joint plate.

[0026] The adjusting mechanism 6 includes a lead screw 61 arranged in the left-right direction and rotationally connected with the first oil injection pipe 2, and a sleeve 62 fixedly connected with the second oil injection pipe 3, and the inner wall of the sleeve 62 is provided with internal threads matched with the external threads of the lead screw 61.

[0027] The lead screw 61 is rotationally connected with the first oil injection pipe 2, and the inner wall of the sleeve 62 fixedly connected with the second oil injection pipe 3 is provided with internal threads matched with the external threads of the lead screw 61, and the user rotates the lead screw 61 to drive the sleeve 62 to move axially along the lead screw 61 through the threaded transmission mechanism, thereby driving the second oil injection nozzle 5 arranged on the second oil injection pipe 3 to move towards or away from the first oil injection nozzle 4.

[0028] The first oil injection pipe 2 is provided with a mounting plate 21, the mounting plate 21 is provided with a mounting hole 211, the lead screw 61 passes through the mounting hole 211, and the lead screw 61 is provided with a limiting portion 611 capable of cooperating with the mounting plate 21 to limit the left-right movement of the first oil injection pipe 2 relative to the lead screw 61.

[0029] The mounting plate 21 is fixed on the first oil injection pipe 2 and the lead screw 61 passes through the mounting hole 211. In the embodiment, the limiting portion 611 is a limiting block arranged on the left and right sides of the mounting plate 21, and the limiting portion 611 cooperates with the mounting plate 21 to prevent the lead screw 61 from moving left and right relative to the first oil injection pipe 2.

[0030] One end of the lead screw 61 is provided with a screwing portion 612 for screwing the lead screw 61.

[0031] Through the arrangement of the screwing portion 612, when the user manually or using a tool rotates the screwing portion 612, the lead screw 61 will be rotated, thereby driving the sleeve 62 matched with the lead screw 61 to move axially along the lead screw 61 through the threaded structure of the lead screw 61.

[0032] The adjusting mechanism 6 can also be realized in other ways, such as by fixing the cylinder of a hydraulic cylinder or pneumatic cylinder with the first oil injection pipe 2, and fixing the output end of the hydraulic cylinder or pneumatic cylinder with the second oil injection pipe 3, and driving the hydraulic cylinder or pneumatic cylinder to drive the second oil injection pipe 3 to move to the required position; or by cooperating a slide rail structure with a locking structure, the first oil injection pipe 2 is fixedly connected with a slide rail, the second oil injection pipe 3 is fixedly connected with a sliding block in sliding connection with the slide rail, and a locking screw is arranged between the slide rail and the sliding block to lock the two, and when the second oil injection pipe 3 moves to the required position, the locking is completed by the locking screw and then the oil injection is performed. In comparison, the screw drive has a simple structure, high positioning accuracy, and can continuously maintain the load position to avoid position changes caused by external forces.

[0033] The first oil injection pipe 2 and the second oil injection pipe 3 are also provided with a guide structure 7 capable of limiting the relative rotation of the first oil injection pipe 2 and the second oil injection pipe 3 when the lead screw 61 rotates.

[0034] When the lead screw 61 is in threaded cooperation with the sleeve 62, the rotation of the lead screw 61 will generate a certain friction force and be converted into a torque acting on the sleeve 62, causing the sleeve 62 to rotate with the lead screw 61, and further causing the first oil injection pipe 2 to rotate relative to the second oil injection pipe 3. Through the arrangement of the guide structure 7, unnecessary relative rotation between the first oil injection pipe 2 and the second oil injection pipe 3 is prevented, and the stability during adjustment is improved.

[0035] The guide structure 7 includes a guide sleeve 71 fixedly connected with the first oil injection pipe 2 and arranged in the left-right direction, and a guide rod 72 fixedly connected with the second oil injection pipe 3 and in sliding cooperation with the guide sleeve 71, the outer wall of the guide rod 72 is provided with an anti-rotation protrusion 721, and the inner wall of the guide sleeve 71 is provided with an anti-rotation groove 711 matched with the anti-rotation protrusion 721.

[0036] The guide rod 72 is provided with an anti-rotation protrusion 721 on the outer wall, which cooperates with the anti-rotation groove 711 in the guide sleeve 71 to prevent the guide rod 72 from rotating around its own axis.

[0037] The guide structure 7 can also be realized in other ways, such as by using two parallel arranged guide columns and guide sleeves, the guide columns are fixed with the first oil injection pipe 2, and the guide sleeves are fixed with the second oil injection pipe 3, so as to only allow the first oil injection pipe 2 and the second oil injection pipe 3 to move in the direction of the guide columns and restrict their rotational movement; or a pair or multiple pairs of linear slide rails can be installed between the first oil injection pipe 2 and the second oil injection pipe 3 to restrict their rotational degrees of freedom. In comparison, the anti-rotation protrusion 721 cooperates with the anti-rotation groove 711, which is simple in structure.

[0038] The three-way pipe 1 and the first oil injection pipe 2, and the three-way pipe 1 and the second oil injection pipe 3 are both provided with on-off valves 8.

[0039] The on / off valve 8 controls whether lubricating oil passes through the corresponding oil injection pipe. When lubrication of one side of the oil injection hole is required, the corresponding on / off valve 8 can be closed to achieve the desired result. At the same time, when the oil injection hole on the unobstructed side is blocked, closing the corresponding on / off valve 8 can prevent excessive pressure from damaging the equipment or causing lubricating oil leakage.

[0040] T-connector 1 is a flexible t-connector 1.

[0041] In embodiment two, the tee tube 1 can be made of materials such as shape memory alloy to give it a certain degree of elasticity. A reset elastic element 9 can be provided between the tee tube 1 or the first oil injection tube 2 and the second oil injection tube 3 to help the tee tube 1 reset, so that the tee tube 1 can deform under external force and return to its initial state after the external force is removed. The connector plate has standard dimensions. In the initial state of the tee tube 1, the distance between the first oil injection nozzle 4 and the second oil injection nozzle 5 is a distance that can match the oil injection holes on both sides of the connector plate, such as... Figure 4 As shown, when installation is required, the user applies force to deform the two output ends of the three-way tube 1 to the left and right, thereby causing the first oil nozzle 4 and the second oil nozzle 5 to move to the left and right. Then, after aligning the first oil nozzle 4 with the oil hole on the unobstructed side, the force is stopped. The three-way tube 1 is restored by the shape memory alloy or reset by the reset elastic element 9, so that the second oil nozzle 5 matches the oil hole on the other side.

[0042] like Figure 4 As shown in Embodiment 2, when using this oil injection device, first connect the input end of the three-way pipe 1 to the oil injection gun. Then, approach the rail joint plate that needs lubrication, observe the oil injection hole on the unobstructed side, and apply force to deform the two output ends of the three-way pipe 1 to the left and right sides. This causes the distance between the first oil injection nozzle 4 and the second oil injection nozzle 5 to be greater than the distance between the two oil injection holes. Then, align the first oil injection nozzle 4 with and insert it into the oil injection hole on that side. After ensuring that the first oil injection nozzle 4 is firmly inserted, stop applying force. The three-way pipe 1 returns to its initial state due to the recovery characteristics of the shape memory alloy or the action of the reset elastic element 9. The second oil injection nozzle 5 then moves and mates with the oil injection hole on the other side. Next, start the oil injection gun. The lubricating oil will be distributed through the three-way pipe 1 to the first oil injection pipe 2 and the second oil injection pipe 3, and then injected into the oil injection holes on both sides of the joint plate from the first oil injection nozzle 4 and the second oil injection nozzle 5. When the lubricating oil is filled to the required amount, turn off the oil injection gun. Then adjust the adjusting mechanism 6 so that the second oil nozzle 5 exits the oil injection hole, and then pull the first oil nozzle 4 out of the oil injection hole to complete one oil injection of the connector plate.
