Description

Technical Field

[0001] This utility model relates to the field of jack technology, and in particular to a fine-tuning jack mechanism. Background Technology

[0002] A jack is a common lifting tool. Through its unique mechanical structure, it generates a huge lifting force with a small amount of force, making it easy to lift heavy objects. In car repair, it is often used to lift the car body to change tires. In construction, it can also help support and adjust the height of heavy objects. Hydraulic jacks are small in size, easy to carry and operate, and play an indispensable role in many fields.

[0003] Existing hydraulic jacks mainly consist of an oil pump, oil cylinder, piston, seals, and handle. Although these hydraulic jacks can lift objects, they lack a fine-tuning structure for lifting height, making it difficult to meet the needs of different height requirements in various work scenarios. Therefore, their applicability is poor. Furthermore, most existing hydraulic jacks lack anti-slip support structures, resulting in weak anti-slip and anti-tilting capabilities, making them prone to tipping and slippage during use.

[0004] Therefore, there is an urgent need to provide a fine-tuning jack mechanism to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fine-tuning jack mechanism.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a fine-tuning jack mechanism is provided, including a base plate mechanism and a lifting mechanism. A hydraulic cylinder mechanism for transmitting hydraulic pressure is sealed and connected on the base plate mechanism, and a lifting mechanism for lifting objects is slidably connected to the inner side of the hydraulic cylinder mechanism.

[0007] An oil supply mechanism is fixed externally to the cylinder mechanism;

[0008] The oil supply mechanism is connected to a drive mechanism for pumping oil into the oil cylinder mechanism.

[0009] The present invention is further configured such that: the substrate mechanism includes a substrate body, a plurality of fastening screws I are provided on the substrate body, and a second fastening screw is also provided on the substrate body.

[0010] Through the above technical solution, the substrate body is made of alloy material, which has the characteristics of high strength, wear resistance and corrosion resistance. The first fastening screw is distributed in an equidistant ring, and the second fastening screw is distributed symmetrically about the central axis of the substrate body.

[0011] The present invention is further configured such that: the hydraulic cylinder mechanism includes a clamping ring bolted to the top of the base plate body, the clamping ring having multiple threaded holes, a sealing gasket being glued and fixed to the bottom end of the clamping ring, and a cylinder body being integrally fixed to the top end of the clamping ring.

[0012] Through the above technical solution, the specifications and positions of the threaded hole and the fastening screw are matched. The fastening screw can fix the clamping ring to the base plate body. When the fastening screw is tightened, the clamping ring and the base plate body will squeeze the sealing gasket, thereby ensuring the sealing of the connection. The inner side of the top of the cylinder is provided with a reverse edge structure.

[0013] The present invention is further configured such that: the lifting mechanism includes a piston slidably disposed inside the cylinder body, the bottom end of the piston is integrally fixed with a protrusion, a sealing ring is inlaid and fixed outside the protrusion, and a threaded groove is formed at the top end of the piston.

[0014] With the above technical solution, when the piston rises, the protrusion can be blocked by the anti-rim structure of the cylinder, thereby preventing the piston from falling out of the cylinder, and the sealing ring can prevent medium leakage at the contact point between the piston and the cylinder.

[0015] The present invention is further configured such that: a threaded rod is threadedly connected to the inner side of the threaded groove, and a lifting part is integrally fixed to the top end of the threaded rod; the top end of the lifting part is machined with friction texture, and the top end of the lifting part is also machined with anti-slip groove.

[0016] Through the above technical solution, the threaded rod and the lifting part together form an adjustment component. When the user screws on the lifting part, the threaded rod rotates in the threaded groove, thereby causing the lifting part to rise or fall, achieving fine adjustment of the lifting part's height. This effectively increases the lifting range of the device. The friction groove effectively increases the top friction of the lifting part, thus preventing the lifted object from slipping. The threaded groove can block the object from sliding laterally, further reducing the possibility of slippage. There are two adjustment components, and the threaded rods of the two adjustment components are of different lengths. The user can screw on and replace different adjustment components according to the actual situation.

[0017] The present invention is further configured such that: the oil supply mechanism includes an oil bag fixed to the outside of the cylinder body, and a valve module is fixed on the oil bag.

[0018] Through the above technical solution, the oil tank is filled with hydraulic oil, the oil inlet channel of the valve module is connected to the inside of the cylinder, the valve module also has a pressure relief function, and the bottom end of the valve module is connected to the fastening screw with two threads, which improves the stability of the valve module and effectively improves the overall robustness of the device.

[0019] The present invention is further configured such that: the driving mechanism includes a gear pump fixed to the valve module, and a drive motor is fixed to the input end of the gear pump.

[0020] With the above technical solution, when the drive motor starts, the gear pump can fill the cylinder with medium through the valve module, thereby raising the lifting mechanism and lifting the object. When lifting is not required, the user can depressurize the medium inside the cylinder through the valve module, so that the medium flows back into the oil tank, thus canceling the lifting.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting up a base plate mechanism, a cylinder mechanism, and an oil supply mechanism, this utility model effectively improves the sealing and robustness of the device, thereby preventing medium oil leakage, structural damage, and extending the service life of the device.

[0023] 2. By setting up a lifting mechanism, this utility model effectively avoids the phenomenon of objects slipping off during the lifting process. At the same time, the user can also fine-tune the height of the lifting mechanism, which not only effectively increases the lifting range of the device, but also improves the accuracy of the lifting height.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] Please see Figures 1-5 A fine-tuning jack mechanism includes a base plate mechanism 1 and a lifting mechanism 3. The base plate mechanism 1 includes a base plate body 101, on which a plurality of fastening screws 102 are inserted and fastening screws 103 are also inserted. The base plate body 101 is made of alloy material, which has the characteristics of high strength, wear resistance and corrosion resistance. The fastening screws 102 are distributed in an equidistant ring, and the fastening screws 103 are distributed symmetrically about the central axis of the base plate body 101.

[0032] like Figure 1 and Figure 3 As shown, a hydraulic cylinder mechanism 2 for transmitting hydraulic pressure is sealed and connected to the base plate mechanism 1. The hydraulic cylinder mechanism 2 includes a clamping ring 201 bolted to the top of the base plate body 101. The clamping ring 201 has multiple threaded holes 202. A sealing washer 203 is also bonded and fixed to the bottom end of the clamping ring 201. A cylinder body 204 is integrally fixed to the top end of the clamping ring 201. The specifications and positions of the threaded holes 202 and the fastening screws 102 are matched. The fastening screws 102 can fix the clamping ring 201 to the base plate body 101. When the fastening screws 102 are tightened, the clamping ring 201 and the base plate body 101 will squeeze the sealing washer 203, thereby ensuring the sealing of the connection. A reverse edge structure is provided on the inner side of the top end of the cylinder body 204.

[0033] like Figure 1 and Figure 4As shown, a lifting mechanism 3 for lifting objects is slidably connected to the inner side of the hydraulic cylinder mechanism 2. The lifting mechanism 3 includes a piston 301 slidably disposed inside the cylinder body 204. A protrusion 302 is integrally fixed to the bottom end of the piston 301, and a sealing ring 303 is inlaid and fixed to the outside of the protrusion 302. A threaded groove 304 is opened at the top end of the piston 301, and a threaded rod 305 is threadedly connected to the inner side of the threaded groove 304. A lifting part 306 is integrally fixed to the top end of the threaded rod 305. Friction grooves 307 are machined on the top end of the lifting part 306, and an anti-slip groove 308 is also machined on the top end of the lifting part 306. When the piston 301 rises, the protrusion 302 can be blocked by the anti-edge structure of the cylinder body 204, thereby preventing the piston 301 from disengaging from the cylinder body 204. The sealing ring 303 can prevent... A medium leak occurs at the contact point between piston 301 and cylinder 204. The threaded rod 305 and the lifting part 306 together form an adjustment component. When the user screws on the lifting part 306, the threaded rod 305 rotates in the threaded groove 304, causing the lifting part 306 to rise or fall, thus achieving fine adjustment of the height of the lifting part 306 and effectively increasing the lifting range of the device. The friction groove 307 effectively increases the friction at the top of the lifting part 306, thereby preventing the lifted object from slipping. The threaded groove 304 can block the object from sliding laterally, further reducing the possibility of the object slipping. There are two adjustment components, and the threaded rods 305 of the two adjustment components are of different lengths. The user can screw on and replace different adjustment components according to the actual situation.

[0034] like Figure 1 and Figure 5 As shown, an oil supply mechanism 4 is fixed externally to the cylinder mechanism 2. The oil supply mechanism 4 includes an oil tank 401 fixed to the outside of the cylinder body 204, and a valve module 402 fixed on the oil tank 401. The oil tank 401 is filled with hydraulic oil. The oil inlet channel of the valve module 402 communicates with the inside of the cylinder body 204. The valve module 402 also has a pressure relief function. The bottom end of the valve module 402 is threadedly connected to the fastening screw 103, which improves the stability of the valve module 402 and effectively improves the overall robustness of the device. The oil supply mechanism 4 is connected to a valve for supplying oil... The cylinder mechanism 2 has an oil pumping drive mechanism 5. The drive mechanism 5 includes a gear pump 501 fixed to the valve module 402. The input end of the gear pump 501 is fixed with a drive motor 502. When the drive motor 502 is started, the gear pump 501 can fill the cylinder 204 with medium through the valve module 402, thereby raising the lifting mechanism 3 and lifting the object. When lifting is not required, the user can depressurize the medium inside the cylinder 204 through the valve module 402, so that the medium flows back into the oil tank 401, thus canceling the lifting.

[0035] When using this utility model, the user can place the device under the object to be lifted and then turn on the lifting switch. At this time, the drive mechanism 5 will pump the medium in the oil supply mechanism 4 to the oil cylinder mechanism 2, so that the lifting mechanism 3 is pressurized and lifted, thereby lifting the object to be lifted. When the lifting is canceled, the user can release the pressure through the valve module 402.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
