[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a hydraulic cylinder for an anti-collision front baffle. 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.

[0003] Existing hydraulic cylinders typically use fixed mounting plates during installation. This method requires two mounting surfaces at the same height or level for successful installation. However, due to structural and space limitations of some equipment, the mounting surfaces of the two plates are often at different heights and angles, and are not on the same plane. This makes hydraulic cylinder installation very difficult. To address these issues, we have introduced a collision-resistant front baffle hydraulic cylinder. Utility Model Content

[0004] This utility model discloses a hydraulic cylinder for a front bumper to prevent collisions. It studies and improves upon the existing structure and its shortcomings, and provides a hydraulic cylinder for a front bumper to prevent collisions, so as to achieve better practical value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic cylinder for a collision avoidance front bumper includes a hydraulic cylinder body. Two mounting plates are disposed at the bottom of the hydraulic cylinder body. A mounting seat is fixedly connected to one side of each mounting plate. A shaft is rotatably connected inside the mounting seat. A mounting cylinder is fixedly connected to one end of the shaft. A connecting plate is fixedly connected to one side of the hydraulic cylinder body. A threaded rod is rotatably connected inside the connecting plate.

[0007] In a preferred embodiment, the limiting assembly includes two mounting rods, both of which are fixedly connected to one side of the mounting base. A baffle is fixedly connected to one end of each mounting rod, and a movable plate is slidably connected to the outer side of each mounting rod. A trapezoidal block is fixedly connected to one side of the movable plate, and the outer side of the trapezoidal block meshes with the interior of a spur gear.

[0008] In a preferred embodiment, a pull rod is fixedly connected to one side of the movable plate, the outer side of the pull rod is slidably connected to the inside of the baffle, and a first spring is provided on the outer side of both the mounting rod and the pull rod.

[0009] In a preferred embodiment, the positioning component includes a fixing block fixedly connected to a connecting plate, a sliding rod slidably connected inside the fixing block, a connecting block fixedly connected to one end of the sliding rod, the bottom of the connecting block slidably connected to the top of the connecting plate, a positioning block fixedly connected to one side of the connecting block, and a second spring provided on the outer side of the sliding rod.

[0010] In a preferred embodiment, the outer side of the rotating block is provided with equidistant positioning grooves, and the outer side of the positioning block abuts against the inside of the positioning grooves.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] The anti-collision front baffle hydraulic cylinder disclosed in this utility model is mainly used in hydraulic cylinder scenarios.

[0024] Reference Figures 1 to 6 A hydraulic cylinder for a collision avoidance front baffle includes: a hydraulic cylinder body 1, two mounting plates 2 at the bottom of the hydraulic cylinder body 1, mounting seats 3 fixedly connected to one side of each mounting plate 2, a shaft 4 rotatably connected inside the mounting seat 3, a mounting cylinder 5 fixedly connected to one end of the shaft 4, a connecting plate 6 fixedly connected to one side of the hydraulic cylinder body 1, a threaded rod 7 rotatably connected inside the connecting plate 6, the outer side of the threaded rod 7 being threadedly connected to the inner side of the mounting cylinder 5, a rotating block 8 fixedly connected to the top of the threaded rod 7, a positioning component on the top of the connecting plate 6, a spur gear 9 fixedly connected to the outer side of the shaft 4, and a limit component on the top of the mounting plate 2;

[0025] The limiting assembly includes two mounting rods 10, both of which are fixedly connected to one side of the mounting base 3. A baffle 11 is fixedly connected to one end of the mounting rod 10, and a movable plate 12 is slidably connected to the outside of the mounting rod 10. A trapezoidal block 13 is fixedly connected to one side of the movable plate 12, and the outside of the trapezoidal block 13 meshes with the inside of the spur gear 9.

[0026] A pull rod 14 is fixedly connected to one side of the movable plate 12. The outer side of the pull rod 14 is slidably connected to the inside of the baffle 11. A first spring 15 is provided on the outer side of both the mounting rod 10 and the pull rod 14.

[0027] In the above technical solution, considering that existing hydraulic cylinders typically use fixed mounting plates during installation, this method requires two mounting surfaces at the same height or level to ensure smooth installation. However, due to structural and space limitations of some equipment, the mounting surfaces of the two plates are often at different heights and angles, and are not on the same plane. In this situation, the installation of the hydraulic cylinder becomes very difficult. To solve this problem, the specific operation is as follows: When the cylinders are not installed on the same plane, by setting a limiting component, simply pull the pull rod 14, thereby moving the movable plate 12 along the surface of the mounting rod 10. The first spring 15 is compressed, and the trapezoidal block 13 is pulled out of the groove of the spur gear 9. Then, rotate the mounting plate 2, so that the mounting plate 2 and the mounting seat 3 rotate around the shaft 4, so that the bottom of the mounting plate 2 fits against the top of the equipment mounting structure. Then, release the pull rod 14. Under the rebound of the first spring 15, the movable plate 12 is reset, and the trapezoidal block 13 re-enters the groove of the spur gear 9. Because the spur gear 9 and the shaft 4 are fixedly connected, the mounting plate 2 can be restricted by the trapezoidal block 13 to prevent the mounting seat 3 from rotating. Then, use bolts to install the hydraulic cylinder body 1 in the designated position. By setting a limit component, the user only needs to pull the lever 14 to make the trapezoidal block 13 disengage from the groove of the spur gear 9, and the mounting plate 2 can rotate freely to adapt to mounting surfaces of different angles and heights. Even if the mounting surfaces are not on the same plane, it can be easily adjusted to the appropriate position.

[0028] Reference Figures 1 to 6 In a preferred embodiment, the positioning component includes a fixing block 16, which is fixedly connected to the connecting plate 6. A slide rod 17 is slidably connected inside the fixing block 16. A connecting block 18 is fixedly connected to one end of the slide rod 17. The bottom of the connecting block 18 is slidably connected to the top of the connecting plate 6. A positioning block 19 is fixedly connected to one side of the connecting block 18. A second spring 20 is provided on the outer side of the slide rod 17. Positioning grooves 21 are equidistantly provided on the outer side of the rotating block 8. The outer side of the positioning block 19 abuts against the inside of the positioning groove 21.

[0029] In the above technical solution, considering that existing hydraulic cylinders typically use fixed mounting plates during installation, this method requires two mounting surfaces at the same height or level to ensure smooth installation. However, due to structural and space limitations of some equipment, the mounting surfaces of the two mounting plates are often at different heights and angles, and are not on the same plane. This makes the installation of the hydraulic cylinder very difficult. To solve this problem, the specific operation is as follows: When the mounting surface heights are often inconsistent, a positioning component is used. Simply pull the slide rod 17 to move the connecting block 18 on the connecting plate 6, compressing the second spring 20 and causing the positioning block 19 to separate from the positioning groove 21. Then, rotate the rotating block 8 to rotate the threaded rod 7, allowing the threaded rod 7 to extend from the mounting cylinder 5. After adjusting the hydraulic cylinder body 1 to a suitable height, release the slide rod 17. Under the elasticity of the second spring 20, the positioning block 19 re-enters the positioning groove 21, restricting the rotating block 8. The positioning component allows the height of the hydraulic cylinder to be adjusted to adapt to mounting surfaces of different heights.

[0030] Reference Figures 1 to 6 In a preferred embodiment, one end of the spur gear 9 and one side of the trapezoidal block 13 are slidably connected to one side of the mounting base 3;

[0031] Working principle: When in use, if the mounting surfaces are not on the same plane, simply pull the pull rod 14 to move the movable plate 12 along the surface of the mounting rod 10. The first spring 15 is compressed, driving the trapezoidal block 13 to exit from the groove of the spur gear 9. Then, rotate the mounting plate 2 so that the mounting plate 2 and the mounting seat 3 rotate around the shaft 4, so that the bottom of the mounting plate 2 fits against the top of the equipment mounting structure. Release the pull rod 14, and under the rebound action of the first spring 15, drive the movable plate 12 to reset. The trapezoidal block 13 re-enters the groove of the spur gear 9, thereby achieving alignment and locking. Since the spur gear 9 is fixedly connected to the shaft 4, the mounting plate 2 is positioned by the trapezoidal block 13 to prevent the mounting seat 3 from rotating. Then, use bolts to install the hydraulic cylinder body 1 in the designated position. When the mounting surfaces are not at the same height, pull the slide bar 17 to move the connecting block 18 on the connecting plate 6, creating a relative positioning effect. At the same time, the second spring 20 is compressed, and the positioning block 19 separates from the positioning groove 21, releasing the constraint on the positioning structure. Rotate the rotating block 8 to rotate the threaded rod 7, causing the threaded rod 7 to extend out of the mounting cylinder 5. Adjust the height of the hydraulic cylinder body 1 to achieve alignment. After adjusting to the appropriate height, release the slide bar 17, the second spring 20 rebounds, and the positioning block 19 re-enters the positioning groove 21, locking the rotating block 8 to ensure stable positioning. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
