[0034] 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.

[0035] Reference Figure 1 - Figure 2This utility model provides an embodiment of a portable liquid suction pump device, including an oil tank 1 for storing oil and a suction pump housing 2. The oil tank 1 is provided with an opening, and the inner wall of the suction pump housing 2 is provided with a suction pump. The suction pump is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. An oil outlet pipe 5 is provided through the upper surface of the suction pump housing 2. A hose can be installed at the oil outlet pipe 5 to facilitate the introduction of oil into other containers. A suction component is provided on the lower surface of the suction pump housing 2. The length of the suction component can be adjusted according to the different models of the oil tank 1. A fixing mechanism is provided on the lower surface of the suction pump housing 2. The fixing mechanism includes a clamping component and a positioning component.

[0036] Reference Figure 1 , Figure 2 , Figure 6 The suction assembly includes an oil suction pipe 61 and an oil outlet pipe 5. The oil suction pipe 61 is connected to the suction pump. Currently, a flexible hose is generally used for suction. However, when the hose is used to suction oil, it tends to float on the surface of the oil and there is a separation between the oil and the inlet, resulting in unstable suction. An extension pipe 62 is slidably connected through the lower surface of the oil suction pipe 61. The extension pipe 62 and the oil suction pipe 61 cooperate to change the overall length to suit different types of oil drums 1. The oil suction pipe 61 is installed through the lower surface of the suction pump housing 2. The bottom end of the extension pipe 62 is fixedly connected to a support base 9. The bottom of the outer wall of the support base 9 has a notch. The support base 9 can contact the bottom end of the inner wall of the oil drum 1 to drain the oil in the oil drum 1. A filter screen is fixed inside the support base 9 to filter impurities.

[0037] Reference Figure 2 , Figure 3 , Figure 5 The clamping assembly includes a fixing ring 71, which is fixedly connected to the lower surface of the suction pump housing 2. A positioning ring 72 is slidably connected to the outer wall of the fixing ring 71. The positioning ring 72 slides longitudinally. A pressure plate 73 is fixedly connected to the right surface of the positioning ring 72. The right end of the pressure plate 73 protrudes from the right end of the suction pump housing 2 for easy pressing. A positioning block 74 is fixedly connected to the lower surface of the positioning ring 72. A round rod 75 is fixedly connected to the inner surface of the positioning block 74. A moving block 76 is slidably connected through the front surface of the fixing ring 71. A clamping plate 77 is fixedly connected to the rear surface of the moving block 76. There are four sets of positioning blocks 74, round rods 75, clamping plates 77 and moving blocks 76, arranged in a circular array with the center of the positioning ring 72 as the origin. A sliding groove 701 is opened through the right surface of the moving block 76.

[0038] Reference Figure 2 , Figure 3 , Figure 5The center points of the fixing ring 71 and the oil suction pipe 61 are located on the same axis. The oil suction pipe 61 is inserted into the opening on the oil drum 1. The fixing ring 71 will surround the opening. The round rod 75 is slidably connected to the inner wall of the slide groove 701. The slide groove 701 is set in an inclined shape with the front lower and the back higher. When the round rod 75 moves longitudinally, it will squeeze the inner wall of the slide groove 701, which will drive the moving block 76 and the clamping plate 77 to open or close synchronously, thereby achieving clamping of the opening. The clamping plate 77 is set in an arc shape to facilitate clamping of the opening of the oil drum 1.

[0039] Reference Figure 1 , Figure 3 , Figure 4 A handle 4 is fixedly connected to the upper surface of the suction pump housing 2. The handle 4 is easy to grip, making the suction pump housing 2 easy to carry and ensuring convenience. A suction pump switch 3 is provided on the right surface of the suction pump housing 2. The suction pump switch 3 and the suction pump are connected by wires. The suction pump switch 3 can control the start and stop of the suction pump. The positioning component includes a pull rod 84, which passes through and is slidably connected to the front surface of the positioning ring 72. A slider 82 is elastically connected to the inner wall of the front side of the positioning ring 72 through a limiting spring 83. A limiting block 81 is fixedly connected to the rear surface of the slider 82. The slider 82 and the limiting block 81 will move synchronously. A limiting groove 801 is opened on the front surface of the fixing ring 71. Multiple sets of limiting grooves 801 are opened and arranged longitudinally at equal intervals.

[0040] Reference Figure 1 , Figure 3 , Figure 4 The pull rod 84 is fixedly connected to the front surface of the slider 82. When the pull rod 84 is pulled, it can drive the slider 82 to move. The slider 82 is slidably connected to the inner wall of the positioning ring 72. When the slider 82 moves forward, it will compress the limiting spring 83 to generate a reaction force. The limiting block 81 passes through and is slidably connected to the inner surface of the positioning ring 72. The limiting block 81 is inserted into the inner wall of the limiting groove 801. The bottom end of the rear surface of the limiting block 81 is set as an inclined surface, which can limit the positioning ring 72 in one direction. When the positioning ring 72 moves downward, the inclined surface of the limiting block 81 will be squeezed and cannot cause the limiting. When the positioning ring 72 moves upward, the inclined surface will not be squeezed and can cause the limiting.

[0041] Reference Figure 1 , Figure 2 , Figure 5 The suction assembly also includes a slot 601, which is located on the inner wall of the front side of the oil suction tube 61. Multiple slots 601 are provided and are distributed longitudinally at equal intervals. The inner wall of the rear side of the extension tube 62 is elastically connected to a block 64 by a compression spring 63. The block 64 and the slot 601 fit together.

[0042] Reference Figure 1 , Figure 2 , Figure 5The locking block 64 is slidably connected to the front surface of the extension tube 62. The locking block 64 is inserted into the inner wall of the slot 601 and can limit the extension tube 62. The front surface of the locking block 64 is set as an arc surface. When the arc surface is squeezed, the locking block 64 will move backward and disengage from the slot 601 to release the limit. However, when there is no external force squeezing, the locking block 64 cannot disengage from the slot 601, so the extension tube 62 can be kept stable.

[0043] Working principle: When using this device, first adjust the extension tube 62 to a suitable position. During adjustment, simply move the extension tube 62 up and down. When the extension tube 62 moves, the arc surface of the locking block 64 will be squeezed, and the locking block 64 will disengage from the locking slot 601 to release the limit. It will also squeeze and compress the spring 63 to generate a reaction force.

[0044] When the extension tube 62 is adjusted to the appropriate position, stop moving. Under the influence of gravity, the extension tube 62 will move slightly downward. When the locking block 64 and the nearest locking slot 601 are aligned, the compression spring 63 will push the locking block 64 and the locking slot 601 to insert into each other, forming a limit and ensuring the stability of the length of the oil extraction tube 61 and the extension tube 62.

[0045] Then, the suction pipe 61 and extension pipe 62 are inserted into the opening of the oil drum 1. After insertion, the support base 9 can contact the bottom of the inner wall of the oil drum 1. At this time, pressing down the pressure plate 73 causes the positioning ring 72 to move downward, which in turn causes the round rod 75 and positioning block 74 to move downward. The downward-moving round rod 75 will squeeze the inner wall of the slide groove 701, which in turn causes the moving block 76 and clamping plate 77 to move closer together to clamp and fix the outer wall of the opening of the oil drum 1, ensuring the stability of the suction pump housing 2 during use. Then, the soft One end of the hose is connected to the oil outlet pipe 5, and the other end of the hose is inserted into the container where oil needs to be extracted. Then, the suction pump switch 3 is operated to start the suction pump to begin suction. After suction is completed, the suction pump switch 3 is operated to turn off the suction pump, and the hose on the oil outlet pipe 5 is removed. Then, the oil extraction pipe 61 and the extension pipe 62 are taken out of the oil drum 1. When taking them out, since the force is vertically upward, the clamp 77 will not cause obstruction. Finally, the extension pipe 62 is pushed into the oil extraction pipe 61, and the device can be moved by grabbing the handle 4.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
