Description

Technical Field

[0001] This utility model relates to the field of lifting cylinder technology, specifically to lifting cylinders. Background Technology

[0002] A lifting cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). When used to achieve reciprocating motion, it eliminates the need for a speed reduction device, eliminates transmission backlash, and ensures smooth movement. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] The existing lifting cylinders cannot be adjusted in terms of installation length. When the installation distance between the two ends is less than the total length of the hydraulic lifting cylinder in its retracted state, a smaller cylinder needs to be replaced to fit the installation space. When the installation distance between the two ends is greater than the total length of the lifting cylinder in its retracted state, the cylinder needs to extend, resulting in insufficient lifting height or failure to reach the expected working range, making it inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting cylinder to solve the problems mentioned in the background art, such as the inability of existing lifting cylinders to adjust their installation length, the need for a smaller cylinder to accommodate the installation space when the installation distance between the two ends is less than the total length of the hydraulic lifting cylinder in its retracted state, and the need for the cylinder to extend when the installation distance between the two ends is greater than the total length of the hydraulic lifting cylinder in its retracted state, resulting in insufficient lifting height or failure to reach the expected working range, making it inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting cylinder, comprising a cylinder body, a second connecting seat fixedly connected to the top of the cylinder body, a base fixedly connected to the bottom of the cylinder body, a mounting hole provided on the surface of the base, a threaded rod slidably connected inside the mounting hole, a mounting ring fixedly connected to the top of the threaded rod, a first fastening nut threadedly connected to the upper surface of the threaded rod, a second fastening nut threadedly connected to the lower surface of the threaded rod, a mounting seat fixedly fixed to the bottom of the threaded rod, a first connecting seat fixedly connected to the bottom of the mounting seat, a fixing seat fixedly connected to the middle of the surface of the cylinder body, fixing blocks fixedly connected to both sides of the fixing seat, hydraulic rods fixedly connected to the tops of both fixing blocks, and connecting blocks fixedly connected to the tops of both hydraulic rods.

[0006] Preferably, there are two connecting blocks, which are symmetrically distributed on both sides of the second connecting seat, and the two connecting blocks are fixedly connected to the second connecting seat on the side closest to the second connecting seat.

[0007] By adopting the above technical solution, and by setting up connecting blocks, second connecting seats, etc. in conjunction with hydraulic rods, hydraulic rods can rise and fall together with the cylinder body. Thus, the connecting blocks provide auxiliary support for the second connecting seats, distributing the weight borne by the cylinder body. This reduces the pressure on the lifting cylinder, decreases wear, and increases its service life.

[0008] Preferably, the number of mounting holes is several, and the several mounting holes are distributed in a circular array on the surface of the base, and the spacing between the several mounting holes is the same.

[0009] Preferably, there are several threaded rods, which are distributed inside several mounting holes, and the diameter of each threaded rod is adapted to the diameter of the mounting hole.

[0010] By adopting the above technical solution, a threaded rod and mounting holes are provided to work with the mounting base. By rotating the first and second fastening nuts, the threaded rod is released from its lock. At this time, the mounting ring can drive the threaded rod to slide in the mounting hole, thereby driving the mounting base to rise or fall, thus changing the installation length of the lifting cylinder to adapt to different installation spaces and facilitate use.

[0011] Preferably, there are several fastening nuts, each of which is located on the upper surface of one of the several threaded rods, and the several fastening nuts are tightly fitted to the top of the base.

[0012] Preferably, there are several fastening nuts, which are located on the lower surface of several threaded rods and are tightly fitted to the bottom of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This lifting cylinder is designed to work with a mounting base by using a threaded rod and mounting holes. By rotating the first and second fastening nuts, the threaded rod can be released from its lock. At this point, the mounting ring can drive the threaded rod to slide in the mounting hole, thereby raising or lowering the mounting base. This changes the installation length of the lifting cylinder, adapting it to different installation spaces and facilitating its use.

[0015] 2. This lifting cylinder, through the use of connecting blocks, a second connecting seat, etc., in conjunction with a hydraulic rod, allows the hydraulic rod to rise and fall together with the cylinder body. The connecting block provides auxiliary support to the second connecting seat, thus distributing the weight borne by the cylinder body. This reduces the pressure on the lifting cylinder, decreases wear, and extends its service life. Attached Figure Description

[0021] 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.

[0022] Example 1:

[0023] Referring to Figures 1-3, the lifting cylinder includes a cylinder body 1. A second connecting seat 14 is fixedly connected to the top of the cylinder body 1, and a base 2 is fixedly connected to the bottom of the cylinder body 1. The surface of the base 2 has several mounting holes 3 arranged in a circular array on the surface of the base 2, with equal spacing between them. Several threaded rods 4 are slidably connected inside the mounting holes 3, and each threaded rod 4 is distributed within one of the mounting holes 3. The diameter of each threaded rod 4 is [not specified in the original text]. The diameter of the mounting hole 3 is compatible. The top of the threaded rod 4 is fixedly connected to the mounting ring 6. The upper surface of the threaded rod 4 is threadedly connected to the fastening nut 1 8. The lower surface of the threaded rod 4 is threadedly connected to the fastening nut 2 9. The bottom of the threaded rod 4 is fixedly connected to the mounting seat 5. The bottom of the mounting seat 5 is fixedly connected to the first connecting seat 7. The middle of the surface of the cylinder body 1 is fixedly connected to the fixing seat 10. The two sides of the fixing seat 10 are fixedly connected to the fixing blocks 11. The top of each of the two fixing blocks 11 is fixedly connected to the hydraulic rod 12. The top of each of the two hydraulic rods 12 is fixedly connected to the connecting block 13.

[0024] Working principle: During use, the operator unscrews fastening nut 8 upwards and fastening nut 9 downwards, releasing the lock on the threaded rod 4. This also creates space, allowing the threaded rod 4 ample room to move. The operator then uses the mounting ring 6 to slide the threaded rod 4 through the mounting hole 3, thereby raising or lowering the mounting seat 5. The mounting seat 5, in turn, raises or lowers the first connecting seat 7, thus changing the installation length of the lifting cylinder. This adapts to different installation spaces without requiring replacement with different sized cylinders, improving work efficiency and facilitating installation.

[0025] Compared with related technologies, the lifting cylinder provided by this utility model has the following beneficial effects: by setting threaded rod 4, mounting hole 3 and other components to cooperate with mounting base 5, the threaded rod 4 can be unlocked by rotating fastening nut 1 8 and fastening nut 2 9. At this time, mounting ring 6 can drive threaded rod 4 to slide in mounting hole 3, thereby driving mounting base 5 to rise or fall, thereby changing the installation length of lifting cylinder, adapting to different installation spaces, and facilitating use.

[0026] Example 2:

[0027] Referring to Figures 1-4, a fixed seat 10 is fixedly connected to the center of the surface of the cylinder body 1. Fixed blocks 11 are fixedly connected to both sides of the fixed seat 10. Hydraulic rods 12 are fixedly connected to the top of each of the two fixed blocks 11. Connecting blocks 13 are fixedly connected to the top of each of the two hydraulic rods 12. There are two connecting blocks 13. The two connecting blocks 13 are symmetrically distributed on both sides of the second connecting seat 14, and the side of the two connecting blocks 13 closest to the second connecting seat 14 is fixedly connected to the second connecting seat 14.

[0028] Working principle: When the cylinder body 1 pushes the second connecting seat 14 to lift the object, the hydraulic rods 12 located on both sides of the cylinder body 1 will also be lifted. The lifting of the hydraulic rods 12 will push the connecting block 13 to rise. The connecting block 13 will provide auxiliary support for the second connecting seat 14, thereby distributing the weight borne by the second connecting seat 14, so that the lifting cylinder can reduce the pressure it bears, reduce the degree of wear, and improve its service life.

[0029] Compared with related technologies, the lifting cylinder provided by this utility model has the following beneficial effects: by setting up a connecting block 13, a second connecting seat 14, etc. to work with the hydraulic rod 12, the hydraulic rod 12 can rise and fall together with the cylinder body 1. Thus, the connecting block 13 provides auxiliary support for the second connecting seat 14, and the weight borne by the cylinder body 1 is distributed, so that the lifting cylinder can reduce the pressure it bears, reduce the degree of wear, and improve its service life.
