Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, and in particular to a hydraulic cylinder. Background Art

[0002] The power of the hydraulic cylinder comes from pressurized hydraulic fluid, which is usually oil. The hydraulic cylinder consists of a cylinder barrel in which a piston connected to a piston rod reciprocates. However, in some current hydraulic cylinders, the cylinder barrel and the mounting base are connected by welding. When the mounting base and the hydraulic cylinder are fixed at a specified position and need to be maintained and disassembled, people also need to use tools to remove the bolts in the base, which is a cumbersome process.

[0003] The existing patent number CN217462720U discloses a hydraulic cylinder, which relates to the technical field of hydraulic cylinders. The bottom surface of the hydraulic cylinder body is provided with a mounting seat, and the surface of the mounting seat is fixedly provided with a fixing block. One side of the mounting seat is rotatably connected with a bidirectional screw rod, and the surface of the bidirectional screw rod is rotatably provided with a threaded block. One side of the threaded block is provided with a connecting block, and one side of the connecting block is fixedly provided with a limiting rod. Limiting holes are provided at both sides of the hydraulic cylinder body near the bottom surface. In actual use, by providing a hydraulic cylinder body, a mounting seat, a fixing block, a bidirectional screw rod, a threaded block, a connecting block, a limiting rod and a limiting hole, the limiting rod is moved between the hydraulic cylinder body by rotating the bidirectional screw rod, which plays a role in disassembling and assembling the hydraulic cylinder body, making it convenient for people to separate the hydraulic cylinder body from the mounting seat, improving the disassembly and assembly efficiency of the hydraulic cylinder body, and being simple and convenient to operate, which is conducive to actual use.

[0004] The above scheme has the following problems during implementation: although the device utilizes the method of rotating the bidirectional screw rod to enable the limit rod to move between the hydraulic cylinder body, thereby making the hydraulic cylinder easier to disassemble and install, when installing the hydraulic cylinder, the limit rod needs to be aligned and inserted into the limit hole before installation. Since the hydraulic cylinder and the fixed block are both cylinders, the limit hole is easily caused to rotate and displace during installation of the hydraulic cylinder, resulting in the limit rod being difficult to accurately insert into the limit hole, greatly reducing the installation efficiency and practicality of the device. To this end, we provide a hydraulic cylinder to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: a hydraulic cylinder, including a mounting seat 1 and a disassembly structure 3, a mounting sleeve 11 is connected to the top of the mounting seat 1, and a hydraulic cylinder body 2 is inserted in the mounting sleeve 11, the hydraulic cylinder body 2 is fixedly installed with the mounting sleeve 11 through the disassembly structure 3, a heat dissipation structure 4 is installed on the upper side of the mounting seat 1, and a positioning structure 5 is installed on one side of the mounting sleeve 11, the positioning structure 5 includes a connecting sleeve 51, a connecting block 53 and a mounting structure 6, and the connecting sleeve 51 is fixedly connected to the outer wall of the mounting sleeve 11, a positioning hole 52 is opened at the top of the connecting sleeve 51, the connecting block 53 is fixedly installed with the hydraulic cylinder body 2 through the mounting structure 6, and a positioning rod 54 is connected to the bottom end of the connecting block 53, and the positioning rod 54 is inserted in the positioning hole 52. This structure makes it possible to position the hydraulic cylinder body 2 during installation, so that the limiting rod 34 can be inserted into the limiting hole 21 more accurately and quickly, and the hydraulic cylinder body 2 is installed, which greatly increases the convenience of installing the hydraulic cylinder body 2. Figure 2 As shown, the inner diameter of the positioning hole 52 is matched with the outer diameter of the positioning rod 54. This structure makes the positioning rod 54 more stable when inserted into the positioning hole 52 and less likely to shake, thereby making the positioning more accurate.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, the disassembly structure 3 includes a fixed block 31, which is fixedly mounted on the top of the mounting seat 1, and a bidirectional screw 32 is rotatably mounted on one side of the fixed block 31, a movable block 33 is threadedly sleeved on the surface of the bidirectional screw 32, and one end of the movable block 33 is connected to a limiting rod 34, and a knob 35 is installed on one end of the bidirectional screw 32. A limiting hole 21 is provided on the lower side of the surface of the hydraulic cylinder body 2, and the limiting rod 34 is inserted into the limiting hole 21. This structure makes it easier to disassemble the hydraulic cylinder body 2, thereby making it easier to repair and replace. Figure 1 and Figure 2 As shown, the heat dissipation structure 4 includes a heat conducting plate 1 41 and a heat conducting plate 2 42. The heat conducting plate 1 41 and the heat conducting plate 2 42 are both sleeved on the surface of the hydraulic cylinder body 2. Fastening bolts 43 are installed on both sides of the heat conducting plate 1 41 and the heat conducting plate 2 42. This structure can dissipate heat for the hydraulic cylinder body 2, thereby increasing the practical life of the hydraulic cylinder body 2.

[0023] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the mounting structure 6 includes a limiting sleeve 1 61 and a limiting sleeve 2 62, and the limiting sleeve 1 61 and the limiting sleeve 2 62 are both sleeved on the lower side of the surface of the hydraulic cylinder body 2, the connecting block 53 is connected to the limiting sleeve 1 61, and one end of the limiting sleeve 1 61 and the limiting sleeve 2 62 are both connected to a fixing sleeve 63, and a locking bolt 64 is inserted in the fixing sleeve 63, and a nut 65 is threadedly sleeved on the surface of the locking bolt 64. This structure makes it possible to fix the connecting block 53 together with the positioning rod 54 to the hydraulic cylinder body 2, and when the hydraulic cylinder body 2 is replaced, the connecting block 53 and the positioning rod 54 can also be removed by the mounting structure 6 and installed on a new hydraulic cylinder body 2 for reuse, which greatly increases the practicality of the device. Figure 3 and Figure 4 As shown, the surface of the hydraulic cylinder body 2 is connected to the limiting block 22, and the inner walls of the limiting sleeve 1 61 and the limiting sleeve 2 62 are both provided with limiting grooves 66, and the limiting block 22 is inserted into the limiting grooves 66. This structure can limit the position of the positioning rod 54, so that the positioning by inserting the positioning rod 54 into the positioning hole 52 is more accurate, as shown in FIG. Figure 2 and Figure 4 As shown, the limiting sleeve 1 61 and the limiting sleeve 2 62 are both semicircular, and the limiting sleeve 1 61 and the limiting sleeve 2 62 can be spliced ​​into a circular ring. This structure makes it fit the surface of the hydraulic cylinder body 2 more closely, so that the installation is more stable.

[0024] Working principle: If the disassembled hydraulic cylinder body 2 and the mounting seat 1 need to be reinstalled, it is only necessary to insert the hydraulic cylinder body 2 into the mounting sleeve 11 and align the positioning rod 54 with the positioning hole 52 and insert it into the positioning hole 52. In this way, the hydraulic cylinder body 2 can be inserted into the mounting sleeve 11 for positioning, thereby positioning the position of the limiting hole 21. At this time, the rotating knob 35 can be operated to drive the bidirectional screw 32 to rotate, and the movable block 33 is driven to move through the thread rotation. The movable block 33 drives the limiting rod 34 to move, so that the limiting rod 34 is accurately inserted into the limiting hole 21 for limiting. In this way, the hydraulic cylinder body 2 is installed, and then the heat conducting plate 1 41 and the heat conducting plate 2 42 are sleeved on the surface of the hydraulic cylinder body 2 and fixed by the fastening bolts 43. In this way, the heat dissipation of the hydraulic cylinder body 2 during operation can be carried out, which greatly increases the convenience of the device.

[0025] In addition, if the hydraulic cylinder body 2 needs to be replaced, it is only necessary to use a tool to remove the nut 65 from the locking bolt 64, and take the locking bolt 64 out of the fixing sleeve 63, so that the limit sleeve 1 61 and the limit sleeve 2 62 can be opened and removed, and then the limit sleeve 1 61 and the limit sleeve 2 62 can be put on the new hydraulic cylinder body 2, and at the same time, the limit block 22 can be inserted into the limit groove 66 to lock and fix the limit sleeve 1 61 and the limit sleeve 2 62, so that the positioning rod 54 can be reused, which greatly increases the practicality of the device.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
