The hand pressure type oil injection device extends the pump rod into the oil tank, and the lower rod is fixed at the oil outlet at the top of the oil drum. The oil is discharged by pressing down.
[0003] After searching, the hand pressure type oil injection device box structure in the patent publication No. CN219606705U proposes "the hand pressure type oil injection device box structure belongs to the technical field of manual oil supply equipment, the bottom of the box is provided with side plates, and the side plates are provided with a moving plate, a roller, a lifting adjusting mechanism and a guide reset mechanism. The utility model is beneficial to the movement of the oil injection device and improves the stability of the oil injection device during operation";
[0004] However, the above-mentioned scheme still has certain deficiencies in actual use. The hand pressure type oil injection device adopts a box body design. Due to the structural limitation, it only allows sliding operation on the ground. This design makes the height of the oil outlet relatively low, so in the actual use process, when the oil injection port located at a higher position needs to be refueled, the operator will face certain inconvenience. This inconvenience mainly reflects in the time consumption and labor intensity during refueling, because the operator needs to take additional measures to overcome the height difference, which not only increases the complexity of the operation, but also makes the entire refueling process more time-consuming and labor-intensive.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figures 1-5 The utility model discloses a hand pressure type oil injection gun, including mobile trolley 1, the top of mobile trolley 1 is provided with oil storage device 2, the top of oil storage device 2 is provided with placing structure 3, the outside of placing structure 3 is swingedly clamped with oil injection gun structure 4.
[0023] The oil storage device 2 includes an oil tank 201, the bottom end of the oil tank 201 is overlapped with the top end of the mobile trolley 1, the side end of the oil tank 201 is provided with an observation window 202, and the top end of the oil tank 201 is fixedly installed with an on-off valve 203.
[0024] The placing structure 3 includes a mounting frame 301, the side end of the mounting frame 301 is provided with a plug-in interface 302, and the oil injection gun structure 4 is swingedly overlapped with the mounting frame 301 through the plug-in interface 302.
[0025] The oil injection gun structure 4 includes a storage tank 401, the inner wall of the storage tank 401 is slidably connected with a piston plate 402 through an outer pull rod 403, the piston plate 402 is overlapped with the inner wall of the storage tank 401, and a damping spring 404 is arranged between the piston plate 402 and the outer pull rod 403.
[0026] The top end of the storage tank 401 is threadedly connected with a top cover 405, one end of the top cover 405 is swingedly connected with an articulated handle 409 through a return spring, and the other end of the top cover 405 is swingedly clamped with an oil outlet head 408 through a connecting pipe 407.
[0027] By using the external pull rod 403, the operator can effectively extract the oil inside the oil storage device 2 into the storage tank 401 with the action of the piston plate 402. This design allows the structure of the oil injection gun to be separated from the oil storage device 2, providing greater flexibility. This flexibility allows the oil injection gun to be used for oil outlets of different heights, whether high or low, oil can be easily extracted. This innovative design not only significantly improves the convenience of using the oil injection gun, but also effectively reduces the labor intensity of the operator. In addition, it also reduces the complexity of the operation process, making the entire oil injection process more time-saving and labor-saving, thereby improving the overall work efficiency.
[0028] Specifically, the side end of the mounting rack 301 is mounted with a limiting clip 303, and the storage tank 401 is overlapped with the inner wall of the limiting clip 303.
[0029] In this embodiment, the design of the limiting clip 303 further enhances the stability of the oil injection gun structure 4 on the placement structure 3. When the oil injection gun structure 4 is actively overlapped with the mounting rack 301 through the plug-in interface 302, the limiting clip 303 can tightly fit the outer wall of the storage tank 401, preventing it from shaking or falling off during work. This stable connection not only ensures the smooth progress of the oil injection process, but also improves the safety of the operation.
[0030] Specifically, the surface of the storage tank 401 is fixedly installed with a handle 406, and the handle 406 is located obliquely below the hinged handle 409.
[0031] In this embodiment, the handle 406 fixedly installed on the surface of the storage tank 401 provides the operator with a convenient gripping point. The handle 406 is located obliquely below the hinged handle 409, which allows the operator to maintain a natural posture when holding the oil injection gun structure 4, reducing hand fatigue. At the same time, the surface of the handle 406 is usually made of anti-slip material to ensure that the operator can firmly hold the oil injection gun structure 4 in a wet or greasy working environment.
[0032] In use, the operator first opens the oil tank 201 through the on-off valve 203, and the observation window 202 can be used to observe the oil remaining in the oil tank 201;
[0033] Then, the operator removes the oil injection gun structure 4 from the placement structure 3, specifically by pulling the oil injection gun structure 4 out of the plug-in interface 302 of the mounting rack 301, while the limiting clip 303 releases the clamping of the storage tank 401;
[0034] Before oil injection, the operator can slide the piston plate 402 in the storage tank 401 by pulling the outer pull rod 403 outward, while the damping spring 404 is compressed. Then, the operator inserts the oil outlet head 408 into the on-off valve 203, and at this time, the oil in the oil tank 201 is sucked into the storage tank 401 under the action of atmospheric pressure, through the connecting pipe 407;
[0035] When oil injection is needed, the operator can hold between the articulated handle 409 and the handle 406, and insert the oil outlet head 408 into the inside of the oil injection port, and press the articulated handle 409 to press the oil in the storage tank 401 into the oil injection port;
[0036] After the oil injection is completed, the operator can close the oil outlet head 408 to prevent oil leakage. Finally, the operator puts the oil injection gun structure 4 back on the placement structure 3, and connects with the mounting frame 301 through the plug-in interface 302, and is fixed by the limiting clamp 303, to complete the entire oil injection process.
[0037] In summary, the hand-pressed oil injection gun can effectively extract the oil in the oil storage device 2 into the storage tank 401 by using the outer pull rod 403 and the action of the piston plate 402. This design allows the structure of the oil injection gun to be separated from the oil storage device 2, providing greater flexibility. This flexibility allows the oil injection gun to be used for oil outlets of different heights, whether high or low, and oil can be easily extracted. This innovative design not only significantly improves the convenience of the oil injection gun, but also effectively reduces the labor intensity of the operator. In addition, it also reduces the complexity of the operation process, making the entire oil injection process more time-saving and labor-saving, thereby improving the overall work efficiency.
[0038] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
