Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically a guide mechanism for hydraulic cylinders. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device. The buffer device and exhaust device are determined according to the specific application, while the other devices are essential.

[0003] A guide device for a hydraulic cylinder, as described in patent application number 202420029486.0, includes a base, a cylinder mounted on the base, a clamping device for holding the cylinder, and a push rod mounted on the cylinder. This device addresses the problem that most hydraulic cylinders in the prior art lack a guiding mechanism during use, which leads to bending or damage after prolonged use, affecting the service life of the hydraulic cylinder. Furthermore, when maintenance and inspection of the guiding mechanism are required, it is not possible to quickly disassemble and install it. In addition, the stability of the guide structure during installation and fixation is low, making disassembly and assembly inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a guide mechanism for hydraulic cylinders to solve the problems of low stability in the installation and fixing of guide structures in the prior art, and inconvenience in disassembly and use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide mechanism for a hydraulic cylinder, comprising a hydraulic cylinder body, a telescopic rod at one end of the hydraulic cylinder body being provided with a guide rod via a detachable first mounting seat, a limiting plate at one end of the guide rod, a second mounting seat being snapped onto the outer wall of the upper end plate at one end of the hydraulic cylinder body, a limiting block being provided on one side of the second mounting seat, and the guide rod being slidably disposed with the guide hole inside the limiting block, a locking pressure plate being provided inside the second mounting seat via a locking bracket, and a locking bolt being threaded onto one end of the locking bracket.

[0006] Furthermore, the first mounting base includes a first connecting seat and a second connecting seat, and the first connecting seat and the second connecting seat are connected and fixed together by a connecting arm, a screw and a nut.

[0007] Furthermore, both the first connecting seat and the second connecting seat have arc-shaped grooves on their inner walls, and the inner walls of the arc-shaped grooves have first anti-slip protrusions.

[0008] Furthermore, the connecting arm is fixedly welded to both ends of the first connecting seat and the second connecting seat, and the screw is vertically welded to one side of the connecting arm of the second connecting seat.

[0009] Furthermore, the second mounting base is a square support, and the locking bracket is a U-shaped bracket, with the locking bracket sliding through the limiting sliding hole at the lower end of the second mounting base.

[0010] Furthermore, the locking plate is a rectangular plate, and a second anti-slip protrusion is provided on the upper side of the locking plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, a guide rod is provided on the outside of the telescopic rod through a detachable first mounting seat. The guide rod is slidably set with a limiting block on the outer wall of the upper end plate. The guide rod and the limiting block can slide and guide the telescopic rod during the extension and retraction adjustment, avoiding bending or damage to the telescopic rod after long-term use, which helps to improve the service life of the pressure cylinder.

[0013] 2. In this utility model, the telescopic rod at one end of the hydraulic cylinder body is provided with a guide rod through a detachable first mounting seat. The first mounting seat includes a first connecting seat and a second connecting seat, and the first connecting seat and the second connecting seat are connected and fixed by a connecting arm, a screw and a nut. The inner wall of the arc-shaped clamping groove of the inner wall of the first connecting seat and the second connecting seat is provided with a first anti-slip protrusion, which makes it easy to install the first mounting seat on the outside of the telescopic rod. The installation and fixing stability is high, and the disassembly and assembly are convenient and quick.

[0014] 3. In addition, the second mounting base of this utility model is provided with a locking plate inside the locking bracket. One end of the locking bracket is threaded with a locking bolt, so that the locking plate is pressed against the lower wall of the upper end plate by rotating the locking bolt. This facilitates the locking of the second mounting base that is snapped onto the outside of the upper end plate, thereby improving the stability of the second mounting base installed outside the hydraulic cylinder body. At the same time, it is convenient and quick to disassemble and assemble, and can be used for guiding hydraulic cylinders of different specifications and sizes. Attached Figure Description
