Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic lifting cylinders, and specifically relates to a simple necking type hydraulic lifting cylinder. Background Technique

[0002] The hydraulic lifting cylinder, as a kind of hydraulic lifting equipment, mainly utilizes the compressibility of the liquid and the principle of hydraulic transmission to realize the lifting of an object. Its basic components include a hydraulic pump, valves, oil pipes, a hydraulic cylinder, a cylinder barrel, and hydraulic oil, etc. The hydraulic pump sucks in and compresses the hydraulic oil, making it flow towards the hydraulic cylinder. When the oil flows into the hydraulic cylinder, the piston inside the hydraulic cylinder will generate a thrust force and lift the object accordingly. On the contrary, if the object needs to be lowered, the oil inside the hydraulic cylinder will be adjusted by the control valve, so that the piston inside the hydraulic cylinder slowly descends and the object is lowered.

[0003] In the related technology, after retrieval, a solution for a hydraulic cylinder sealing device (publication number: CN212717482U) was found, including: a cylinder body, a piston rod movably arranged inside the cylinder body, and a piston arranged on the piston rod; a first sealing assembly adapted to seal the inside of the cylinder body is arranged on the piston; a second sealing assembly adapted to seal the outside of the cylinder body is arranged at the connection between the cylinder body and the piston rod. However, the sealing structure in the above use is simple, and it is still prone to leakage problems when the load pressure is too large. The hydraulic oil in the above hydraulic cylinder will leak out, which not only wastes resources but also may cause environmental pollution. The leaked hydraulic oil often has certain corrosiveness and pollution, posing potential hazards to the equipment and the surrounding environment. In view of this, we introduce a simple necking type hydraulic lifting cylinder. Summary of the Invention

[0004] The purpose of the utility model is to provide a simple necking type hydraulic lifting cylinder to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A simple necking type hydraulic lifting cylinder, including: a positioning frame, a driver, and a base;

[0006] A controller is arranged on one side of the positioning frame, and a side frame is connected to one side of the positioning frame;

[0007] The driver is arranged on one side of the side frame, and a positioning disk is connected to one side of the driver;

[0008] The base is arranged at the bottom of the positioning frame, and the base and the positioning frame are connected by a threaded rod. A sealing mechanism is arranged on the surface of the base. The hydraulic lifting cylinder passes through the sealing mechanism and is inside the positioning ring of the base, so that the hydraulic lifting cylinder forms a seal.

[0009] Preferably, the sealing mechanism includes an external thread portion connected to the bottom of the hydraulic lifting cylinder. The external thread portion and the hydraulic lifting cylinder are integrally formed. One side of the positioning frame is provided with a U-shaped groove, and the U-shaped groove and the positioning frame are integrally formed. The hydraulic lifting cylinder is connected to the surface of the U-shaped groove. The diameter of the hydraulic lifting cylinder is 49 mm. The positioning ring is connected to one side of the base. An internal thread portion is provided inside the positioning ring, and the internal thread portion and the positioning ring are integrally formed. The external thread portion is screwed with the internal thread portion. The top of the hydraulic lifting cylinder is provided with a necking, and the size of the necking is 47 mm. A lifting screw rod is connected to the top of the hydraulic lifting cylinder.

[0010] Preferably, a battery is connected to one side of the positioning disk.

[0011] Preferably, a bolt is connected to the surface of the driver. The bolt passes through the driver and the positioning disk and is screwed inside the battery. The bolt can fix the driver, the positioning disk and the battery.

[0012] Preferably, anti-slip nails are equidistantly connected to the bottom of the base. The anti-slip nails are in contact with the ground, which can increase the friction of the base, and thus the grip is stronger.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By screwing the external thread portion at the bottom of the hydraulic lifting cylinder through the U-shaped groove into the internal thread portion inside the positioning ring, since the external thread portion and the internal thread portion are matched and screwed, the hydraulic lifting cylinder can be installed inside the positioning ring. Then, the hydraulic lifting cylinder can be further installed by using the fixed installation bracket on the surface of the positioning ring, so that the sealing between the hydraulic lifting cylinder, the positioning ring and the sealing gasket is strengthened, which can adapt to excessive load pressure, thus avoiding leakage, and the sealing performance is good. At the same time, the overall material is reduced, and the lifting is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a simple closing type hydraulic lifting cylinder, including: a positioning frame 11, a controller 10 is arranged on one side of the positioning frame 11, and a side frame 9 is connected to one side of the positioning frame 11;

[0020] A driver 8, the driver 8 is arranged on one side of the side frame 9, and a positioning disk 7 is connected to one side of the driver 8;

[0021] A base 13, the base 13 is arranged at the bottom of the positioning frame 11, and a sealing mechanism is arranged on the surface of the base 13. The hydraulic lifting cylinder 3 of the sealing mechanism is inside the positioning ring 14 of the base 13, so that the hydraulic lifting cylinder 3 forms a seal.

[0022] The sealing mechanism includes an external thread portion 4 connected to the bottom of the hydraulic lifting cylinder 3. The external thread portion 4 and the hydraulic lifting cylinder 3 are integrally formed. A U-shaped groove 12 is opened on one side of the positioning frame 11, and the U-shaped groove 12 and the positioning frame 11 are integrally formed. The hydraulic lifting cylinder 3 is connected to the surface of the U-shaped groove 12. The diameter of the hydraulic lifting cylinder 3 is 49 mm. The positioning ring 14 is connected to one side of the base 13. An internal thread portion 15 is arranged inside the positioning ring 14, and the internal thread portion 15 and the positioning ring 14 are integrally formed. The external thread portion 4 is screwed with the internal thread portion 15. A closing 2 is arranged at the top of the hydraulic lifting cylinder 3, and the size of the closing 2 is 47 mm. A lifting screw rod 1 is connected to the top of the hydraulic lifting cylinder 3.
