[0002] A hydraulic jack is a device that works on the principle of hydraulic transmission. Its core working principle is based on Pascal's principle, which states that the pressure of a liquid in a closed container is the same in any direction. In a hydraulic jack, a small piston generates a small pressure through human or mechanical force. This pressure is transmitted to a large piston through hydraulic oil. As the area increases, the force generated also increases accordingly, thereby achieving the lifting of heavy objects.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The following is combined with Figure 1-7 To further explain this application,

[0026] The present application discloses a portable lithium battery driven hydraulic jack. Figure 1-5 A portable lithium-battery driven hydraulic jack includes a hydraulic jack 1. A telescopic mechanism 2 is provided on one side of the hydraulic jack 1. The hydraulic jack 1 is driven by a lithium battery, making the hydraulic jack 1 suitable for use in occasions where mobility is required. The telescopic mechanism 2 can be inserted into the corresponding interface of the hydraulic jack 1 and controls the lifting and lowering of the hydraulic jack 1 by moving up and down.

[0027] The telescopic mechanism 2 includes a third operating rod 203, the surface of the third operating rod 203 is slidably connected to the inner cavity of the hydraulic jack 1, the surface of the third operating rod 203 is slidably connected to the second operating rod 202, the surface of the second operating rod 202 is slidably connected to the first operating rod 201, one side of the first operating rod 201 is fixedly connected to a hollow block 204, the inner cavity of the hollow block 204 is slidably connected to an insertion rod 205, the top of the hollow block 204 is fixedly connected to a spring 206, the top of the spring 206 is fixedly connected to a connecting block 207, the bottom of the connecting block 207 is fixedly connected to the top of the insertion rod 205, a first slot 208 is provided on the surface of the second operating rod 202, and a second slot 209 is provided on the surface of the hydraulic jack 1;

[0028] The first operating rod 201, the second operating rod 202 and the third operating rod 203 can be connected to form a rod, and the third operating rod 203 can be inserted into the corresponding interface of the hydraulic jack 1, and by moving the first operating rod 201 up and down, the second operating rod 202 and the third operating rod 203 can be driven to move, thereby controlling the lifting and lowering of the hydraulic jack 1. The interior of the hollow block 204 can be used to place the plug rod 205, so that the plug rod 205 can slide, and the connecting block 207 can connect the plug rod 205 and the spring 206, so that the plug rod 205 can be stabilized in the interior of the hollow block 204 and is not prone to falling off from the hollow block 204. At the same time, the elastic force of the spring 206 can also make the plug rod 205 move smoothly, and the plug rod 205 can move into the interior of the first slot 208 to achieve the effect of limiting and fixing the first operating rod 201, so that the first operating rod 201 is on the surface of the second operating rod 202 When the hydraulic jack 1 cannot be moved, the first operating rod 201 can be moved up and down, and the lifting and lowering of the hydraulic jack 1 can be controlled by moving the second operating rod 202 and the second operating rod 202. At the same time, the insertion rod 205 can also be separated from the first slot 208, so that the first operating rod 201 can slide on the surface of the second operating rod 202, and the second operating rod 202 can also slide on the surface of the first operating rod 201, thereby achieving a contraction effect, which can effectively reduce the length of the first operating rod 201, so that the first operating rod 201 and the hydraulic jack 1 will not take up much space, thereby facilitating the storage and carrying of the hydraulic jack 1. The second slot 209 is opened, so that the insertion rod 205 can be moved into the inside of the second slot 209, thereby fixing the retracted first operating rod 201, which makes it difficult for the first operating rod 201 to slip out when carried, so that it can be stably in the retracted state.

[0029] Reference Figure 6-7The surface of the third operating rod 203 is provided with a first slide groove 3 and a second slide groove 4. The inner cavity of the second slide groove 4 is slidably connected to the slider 5. The top of the slider 5 is fixedly connected to the inner cavity of the second operating rod 202. The slider 5 can be placed inside the first slide groove 3 and the second slide groove 4, so that the slider 5 can slide inside the first slide groove 3 and the second slide groove 4. The slider 5 is connected to the second operating rod 202, so that when the second operating rod 202 slides on the surface of the third operating rod 203, the second slide groove 4 can limit the slider 5, so that the second operating rod 202 is not easy to separate from the third operating rod 203, and the slider 5 can also move into the second slide groove 4. Internally, this makes it difficult for the second operating rod 202 to move back and shrink after sliding open on the surface of the third operating rod 203, and is more stable. The slider 5 can also rotate ninety degrees and move into the interior of the first slide groove 3, so that the second operating rod 202 can slide on the surface of the third operating rod 203 and shrink. The second operating rod 202 is square, which allows the first operating rod 201 to smoothly drive the second operating rod 202 and the slider 5 to rotate together when rotating. After the first operating rod 201 and the slider 5 rotate ninety degrees, the insertion rod 205 will also rotate ninety degrees. At this time, the insertion rod 205 can smoothly move into the second slot 209.

[0030] Reference Figure 7 The inner cavity of the second slide groove 4 is fixedly connected to the first magnet block 6, and a second magnet block 7 is provided on one side of the first magnet block 6. One side of the second magnet block 7 is fixedly connected to one side of the slider 5. The first magnet block 6 and the second magnet block 7 can be magnetically adsorbed together, which makes the slider 5 more stable when sliding into the interior of the second slide groove 4, making it difficult for the second operating rod 202 to rotate.

[0031] Reference Figure 4 A hollow groove 8 is provided on the surface of the third operating rod 203, and a limit block 9 is provided in the inner cavity of the hollow groove 8. The bottom of the limit block 9 is fixedly connected to the inner cavity of the hydraulic jack 1. The limit block 9 can be placed inside the hollow groove 8, and the limit block 9 can limit the third operating rod 203 through the hollow groove 8, so that the third operating rod 203 cannot rotate inside the hydraulic jack 1, and then when the first operating rod 201 drives the second operating rod 202 to rotate, the third operating rod 203 will not rotate together.

[0032] Reference Figure 4 A first thread groove 10 is provided on the surface of the hydraulic jack 1, and a threaded rod 12 is threadedly connected to the inner cavity of the first thread groove 10. A second thread groove 11 is provided on the surface of the third operating rod 203, and the surface of the threaded rod 12 is threadedly connected to the inner cavity of the second thread groove 11. The threaded rod 12 can be rotated and moved into the interior of the second thread groove 11 and the first thread groove 10 to fix the third operating rod 203, so that the third operating rod 203 can stabilize the interior of the hydraulic jack 1 and is not easy to fall out.

[0033] Reference Figure 3 The top of the connecting block 207 is fixedly connected with a fixing rod 13, which is T-shaped. The fixing rod 13 allows people to pull the connecting block 207 and the insertion rod 205 upward to disengage the first slot 208 more conveniently and simply by hooking the T-shaped fixing rod 13 with two fingers.

[0034] Reference Figure 6 The surface of the first operating rod 201 is provided with anti-slip grooves 14, and a plurality of anti-slip grooves 14 are provided. The anti-slip grooves 14 can make people more stable when moving the first operating rod 201 up and down, and are less likely to slip.

[0035] Working principle: When using this device, first slide the third operating rod 203 into the corresponding interface of the hydraulic jack 1, and then move the first operating rod 201 up and down to control the hydraulic jack 1 to rise and fall through the second operating rod 202 and the third operating rod 203. When it is necessary to carry the hydraulic jack 1, the connecting block 207 can be pulled first to drive the insertion rod 205 to move up, and at the same time the insertion rod 205 will be disengaged from the inside of the first slot 208. At this time, the first operating rod 201 can slide and shrink on the surface of the second operating rod 202, and then rotate the first operating rod 201 to drive the square second operating rod 202 to rotate. The second operating rod 202 will drive the slider 5 to slide from the inside of the second slide groove 4 into the inside of the first slide groove 3, and through the first slide groove 3, the first operating rod 201 and the second operating rod 202 can slide and shrink on the surface of the third operating rod 203. At this time, the first operating rod 201, the second operating rod 2 When the first operating rod 201 is aligned with the second slot 209, it will be rebounded into the second slot 209 by the spring 206, thereby fixing the first operating rod 201. At this time, the first operating rod 201 and the second operating rod 202 cannot slide, so that they can be stably in the retracted state. Since the first operating rod 201, the second operating rod 202 and the third operating rod 203 have been retracted together, the length of the first operating rod 201 can be effectively reduced, so that the first operating rod 201 and the hydraulic jack 1 will not take up much space, thereby facilitating the storage and carrying of the hydraulic jack 1. At this point, the problem that the first operating rod 201 is long and takes up a lot of space when carrying the hydraulic jack 1, making it inconvenient to store and carry the hydraulic jack 1, can be solved.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
