Description

Technical Field

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

[0002] A hydraulic cylinder primarily consists of a barrel, piston, piston rod, sealing device, buffer, and exhaust device. The barrel, as the main structure of the hydraulic cylinder, provides a stable space for the piston's movement. It is typically manufactured from high-strength alloy steel or high-quality carbon steel to ensure it can withstand the tremendous pressure of high-pressure liquids and exhibits excellent wear and corrosion resistance. The piston is installed within the barrel, dividing the barrel into two working chambers. Hydraulic fluid is fed into and out of these chambers to propel the piston in reciprocating linear motion. Its structural design must ensure a good fit with the inner wall of the barrel to achieve efficient sealing and smooth movement.

[0003] The hydraulic cylinder lacks a protective function during use, which may cause damage due to external influences. However, if the protective function is simply added, when the protective structure needs to be installed, it cannot achieve good installation efficiency, reducing the convenience of device operation. Utility Model Content

[0004] The purpose of the present utility model is to provide a hydraulic cylinder with a protection mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a hydraulic cylinder with a protective mechanism, comprising a hydraulic cylinder body, a mounting mechanism provided on the top of the hydraulic cylinder body, and a protective mechanism provided on one side of the mounting mechanism;

[0006] The mounting mechanism includes a fixed box, which is arranged on one side of the protective mechanism. A spring is fixedly connected to the inner wall of the fixed box, one end of the spring is fixedly connected to a rectangular plate, the top of the rectangular plate is fixedly connected to a push block, one side of the rectangular plate is fixedly connected to a clamping block, the side of the rectangular plate away from the clamping block is fixedly connected to a pull rod, the end of the pull rod away from the rectangular plate is rotatably connected to a dislocation block, and the side of the fixed box away from the fixed groove is fixedly connected to a limiting block.

[0007] Preferably, a moving opening is opened on the top of the fixed box, and the push block passes through the moving opening and moves, so that the push block can move through the moving opening.

[0008] Preferably, a through hole is provided on a side of the fixing box away from the protective mechanism, and the pull rod passes through the through hole and moves, so that the pull rod can move through the through hole.

[0009] Preferably, the rectangular plate is slidably connected to the inner wall of the fixed box, and the spring is sleeved on the outer wall of the pull rod, so that the rectangular plate moves stably to compress the spring.

[0010] Preferably, the protective mechanism includes a fixing groove, which is fixedly connected to the top of the hydraulic cylinder body. A protrusion is movably connected inside the fixing groove, and a protective cover is fixedly connected to the outside of the protrusion, which can protect the hydraulic cylinder body and ensure that the hydraulic cylinder body can work stably.

[0011] Preferably, the fixing slot is fixedly connected to one side of the fixing box, and the clamping block passes through the fixing slot and moves, so that the clamping block can limit the protrusion by moving through the fixing slot.

[0012] Preferably, a bayonet is provided on the outer side of the protrusion, and the clamping block is movably connected to the inner wall of the bayonet, so that the clamping block and the bayonet cooperate with each other to limit the protrusion.

[0013] Compared with the prior art, the present invention provides a hydraulic cylinder with a protective mechanism, which has the following beneficial effects:

[0014] 1. The hydraulic cylinder with a protective mechanism uses an installed mechanism to prevent the dislocation block from being aligned with the limit block. At this time, the spring in a compressed state pushes the card block through the rectangular plate to insert into the inside of the protrusion, limiting the protrusion so that the protrusion cannot move out of the fixing groove. When the protective cover needs to be installed, good installation efficiency can be achieved, which enhances the convenience of operation and use of the device.

[0015] 2. The hydraulic cylinder with a protective mechanism has a protective cover that can protect the hydraulic cylinder body through the protective mechanism. At the same time, the protrusion can be inserted into the inside of the fixed groove to ensure the stability of the protective cover. At the same time, it can reduce the impact of the outside world on the hydraulic cylinder body, making it easier for the hydraulic cylinder body to be operated and used better.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] The utility model provides the following technical solutions:

[0026] Example 1

[0027] Combine Figures 1 to 5 A hydraulic cylinder with a protective mechanism includes a hydraulic cylinder body 1, a mounting mechanism 2 is provided on the top of the hydraulic cylinder body 1, and a protective mechanism 3 is provided on one side of the mounting mechanism 2;

[0028] The mounting mechanism 2 includes a fixed box 21, which is arranged on one side of the protective mechanism 3. A spring 22 is fixedly connected to the inner wall of the fixed box 21, one end of the spring 22 is fixedly connected to a rectangular plate 23, the top of the rectangular plate 23 is fixedly connected to a push block 24, one side of the rectangular plate 23 is fixedly connected to a clamping block 25, a side of the rectangular plate 23 away from the clamping block 25 is fixedly connected to a pull rod 26, an end of the pull rod 26 away from the rectangular plate 23 is rotatably connected to a dislocation block 27, and a side of the fixed box 21 away from the fixing groove 31 is fixedly connected to a limiting block 28.

[0029] Furthermore, a moving opening is opened on the top of the fixed box 21, and the push block 24 passes through the moving opening and moves, so that the push block 24 can move through the moving opening.

[0030] Furthermore, a through hole is opened on a side of the fixing box 21 away from the protection mechanism 3 , and the pull rod 26 passes through the through hole and moves, so that the pull rod 26 can move through the through hole.

[0031] Furthermore, the rectangular plate 23 is slidably connected to the inner wall of the fixed box 21 , and the spring 22 is sleeved on the outer wall of the pull rod 26 , so that the rectangular plate 23 moves stably to compress the spring 22 .

[0032] Example 2

[0033] See Figures 1 to 5 On the basis of the first embodiment, the protective mechanism 3 further comprises a fixing groove 31, the fixing groove 31 is fixedly connected to the top of the hydraulic cylinder body 1, a protrusion 32 is movably connected inside the fixing groove 31, and a protective cover 33 is fixedly connected to the outside of the protrusion 32, which can protect the hydraulic cylinder body 1 and ensure that the hydraulic cylinder body 1 can work stably.

[0034] Furthermore, the fixing groove 31 is fixedly connected to one side of the fixing box 21, and the block 25 passes through the fixing groove 31 and moves, so that the block 25 can move through the fixing groove 31 to limit the protrusion 32.

[0035] Furthermore, a bayonet is provided on the outer side of the protrusion 32 , and the clamping block 25 is movably connected to the inner wall of the bayonet, so that the clamping block 25 and the bayonet cooperate with each other to limit the protrusion 32 .

[0036] During actual operation, when this device is used, during the use of the hydraulic cylinder body 1, the protective cover 33 can protect the hydraulic cylinder body 1. At the same time, the protrusion 32 can be inserted into the inside of the fixing groove 31 to ensure the stability of the protection of the protective cover 33. At the same time, it can reduce the impact of the outside world on the hydraulic cylinder body 1, so that the hydraulic cylinder body 1 can be better operated and used.

[0037] When it is necessary to install and connect the protective cover 33, the push block 24 can be pushed to drive the rectangular plate 23 to move, and the rectangular plate 23 can drive the clamping block 25 to move, and the rectangular plate 23 will also drive the dislocation block 27 to move through the pull rod 26. The rectangular plate 23 can also compress the spring 22 during the movement. When the dislocation block 27 moves to the side where the limit block 28 is away from the fixed box 21, the dislocation block 27 can be rotated ninety degrees along the axis of the pull rod 26 so that the dislocation block 27 can be stuck on the side where the limit block 28 is away from the fixed box 21, and the dislocation block 27 can be installed. To ensure that the pull rod 26 is limited, the block 25 cannot be pushed and moved. At this time, the protrusion 32 can be inserted into the inner side of the fixed groove 31, and then the offset block 27 is rotated again so that the offset block 27 is not aligned with the limit block 28. At this time, the spring 22 in a compressed state will push the block 25 through the rectangular plate 23 to insert into the inside of the protrusion 32, limiting the protrusion 32 so that the protrusion 32 cannot be moved out of the inside of the fixed groove 31. When the protective cover 33 needs to be installed, good installation efficiency can be achieved, which enhances the convenience of operating the device.
