Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder with an external protective structure. Background Art

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating or swinging motion. It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed 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 the exhaust device depend on the specific application scenario, and other devices are indispensable.

[0003] After searching the existing published patent application number: CN202221097121.9, the name of the published patent is: A hydraulic cylinder with an external protective structure, including a hydraulic cylinder, an outer guard plate and a hydraulic rod, wherein the outer side of the outer guard plate near the center of the hydraulic cylinder is fixedly connected to a support plate, and the outer side of the other end of the support plate is fixedly connected to an inner guard plate, the inner guard plate is slidably connected to the hydraulic cylinder, and the outer side of the outer guard plate is fixedly connected to a sleeve, and the inner side of the sleeve is slidably connected to a positioning rod. Through the outer guard plate, support plate, inner guard plate and positioning rod, when the hydraulic cylinder is impacted by an external object, the external object rests on the outer guard plate, and then the connecting plate drives the buffer plate to prevent the external object from buffering the hydraulic cylinder, so that the outer guard plate slides on the hydraulic cylinder, and the external object is forced to deviate through the arc-shaped outer guard plate, and mechanically buffered by the positioning rod in the sleeve, and the impact of the external object is reduced by the double-layer guard plate.

[0004] However, when the above device is in use and encounters a heavy object that needs to be lifted, the hydraulic cylinder has a poor fixing effect and is prone to deviation and damage, thereby reducing its service life. There is room for improvement. Utility Model Content

The positioning block 2 is set in the center of the upper surface of the base 1, and a rubber pad is installed on the top of the positioning block 2.

[0028] Analysis of the above content: The hydraulic cylinder body 3 is placed on top of the positioning block 2. The rotating disk 604 drives the threaded rod 603 to rotate along the base 1, thereby causing the sliding frame 602 to slide along the positioning rod 601. The sliding frame 602 drives the protective plates 606 to approach each other. The protective plates 606 are used to clamp and fix the hydraulic cylinder body 3 to ensure the stability of the hydraulic cylinder body 3 during use.

[0031] Analysis of the above content: Pull the sliding frame 602 to make the sliding frame 602 slide along the surface of the positioning rod 601. After sliding to the desired position, rotate the adjusting nut 609 so that the adjusting nut 609 locks the position of the sliding frame 602, which is convenient for fixing the hydraulic cylinder body 3 of different sizes.

[0033] See also Figure 1-4The present invention provides a technical solution based on the first embodiment: a handle 9 is symmetrically provided on one side of the base 1, and the surface of the handle 9 is provided with anti-slip grooves.

[0034] Analysis of the above content: The handle 9 is provided to facilitate the taking and movement of the base 1. The anti-slip grooves are provided to increase the friction and prevent the base 1 from falling when it is moved.

[0036] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: the protective plate 606 is arranged in an arc shape, and the threaded rod 603 is arranged in the middle position on one side of the sliding frame 602.

[0037] Analysis of the above content: The arc-shaped setting of the protective plate 606 is more closely aligned with the surface of the hydraulic cylinder body 3, thereby improving the fixing effect of the hydraulic cylinder body 3. The threaded rod 603 is set in the center of one side of the sliding frame 602, so that the surface of the sliding frame 602 is more evenly stressed, thereby better fixing the hydraulic cylinder body 3.

[0039] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: a movable component 7 is provided at the bottom of the base 1, and the movable component 7 includes a positioning groove 701 opened at the bottom of the base 1, a mounting frame 702 is fixedly connected in the positioning groove 701, a connecting frame 703 is rotatably connected to the mounting frame 702, a roller 704 is rotatably connected to the surface of the connecting frame 703, and a torsion spring 705 is symmetrically provided on the surface of the connecting frame 703.

[0040] Analysis of the above content: When the hydraulic cylinder body 3 is not in use, under the action of the torsion spring 705, the connecting frame 703 drives the roller 704 to move downward, so that one side of the base 1 is lifted up, so that the support block 10 is lifted off the ground, and the handle 9 is pulled to cooperate with the roller 704 to facilitate the movement of the base 1.

[0041] Example 6:

[0042] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: one end of the torsion spring 705 is fixedly connected to one side of the connecting frame 703 , and the other end of the torsion spring 705 is fixedly connected to the inner wall of the positioning groove 701 .

[0043] Analysis of the above content: Under the action of the torsion spring 705, the roller 704 moves downward, thereby lifting one side of the base 1 to facilitate the movement of the base 1. When the hydraulic cylinder body 3 is in use, the base 1 is squeezed downward, and the support block 10 contacts the ground to ensure the stability of the hydraulic cylinder body 3.
