Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a hydraulic cylinder that is easy to install. Background Technology

[0002] Hydraulic cylinders, as actuators in hydraulic systems, are widely used in various industrial fields, such as construction machinery, metallurgy, mining, and shipbuilding. They convert the pressure energy of hydraulic oil into mechanical energy to achieve linear reciprocating motion or oscillating motion, thereby completing various work tasks, such as pushing loads, lifting heavy objects, and controlling mechanical movement. With the continuous development of industry, the performance requirements for hydraulic cylinders are also becoming increasingly stringent, such as higher working pressure, greater load capacity, more precise motion control, longer service life, and better sealing performance.

[0003] Traditional hydraulic cylinder installation typically requires a large number of bolts, nuts, and other connectors, making the process cumbersome, time-consuming, and labor-intensive. In situations with limited space or complex installation environments, the difficulty is even greater. Furthermore, some existing fixing methods may not be suitable for different specifications and models of hydraulic cylinders, resulting in poor versatility. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a hydraulic cylinder that is easy to install.

[0005] This utility model is achieved by the following technical solution: a hydraulic cylinder that is easy to install, including a hydraulic cylinder body, the hydraulic cylinder body is placed on the top of the mounting platform, the surface of the hydraulic cylinder body is in contact with clamping blocks, four clamping blocks are provided, protective cotton is fixedly connected to the ends of the four clamping blocks that are close to each other, and transmission rings are fixedly connected to the ends of the four clamping blocks that are far apart from each other, and four transmission rings are provided.

[0006] Through the above technical solution, the four clamping blocks, through the transmission structure consisting of a transmission ring, a rotating rod, and a rotating handle, can conveniently clamp and fix the hydraulic cylinder body, ensuring the stability of the hydraulic cylinder during operation and preventing it from shaking or displacing due to external forces. This ensures the working accuracy and safety of the hydraulic cylinder. Protective cotton is fixedly connected to the ends of the clamping blocks that are close to each other. When clamping the hydraulic cylinder body, the protective cotton can not only act as a buffer to prevent the hydraulic cylinder body from being pinched, but also increase friction to make the clamping more stable. The transmission ring transmits the rotational force of the rotating handle to the rotating rod, and the rotating rod then transmits the force to the clamping blocks, realizing the effective transmission of force and the conversion of direction. This allows the operator to easily control the clamping and releasing actions of the clamping blocks by rotating the rotating handle, making the operation simple and convenient.

[0007] As a further improvement to the above scheme, the four transmission rings are connected to rotating rods at their ends that are far apart from each other. There are four rotating rods, and the four rotating rods are fixedly connected to rotating handles at their ends that are far apart from each other.

[0008] Through the above technical solution, the cooperation of the four transmission rings and rotating rods can ensure the synchronicity of the four clamping blocks during the clamping and releasing process, so that the hydraulic cylinder body is subjected to uniform clamping force, further improving the stability and reliability of clamping.

[0009] As a further improvement to the above solution, four rotating handles are provided, and four fixing plates are sleeved on the surfaces of the four rotating handles. The bottom ends of the four fixing plates are fixedly connected to the top of the mounting platform.

[0010] The design of the rotating handle in the above technical solution facilitates operation. By simply rotating the handle, the hydraulic cylinder body can be clamped and released without the need for complex tools or equipment, reducing operational difficulty and labor intensity, and improving work efficiency. Four fixing plates are fitted onto the surfaces of the rotating handles, with the bottom ends of the fixing plates fixedly connected to the top of the mounting platform. This structural design makes the rotating handles more stable during operation, preventing wobbling or deviation, thus ensuring the accuracy and stability of the clamping block's gripping of the hydraulic cylinder body.

[0011] As a further improvement to the above solution, the top end of the hydraulic cylinder body contacts the bottom end of the top cover, and the top end of the top cover is threadedly connected to the top end of the hydraulic cylinder body by bolts. Several bolts are provided, and a locking pin is fixedly connected to the top end of the cover. A locking groove is opened on the top end of the hydraulic cylinder body, and the surface of the locking pin engages with the inner wall of the locking groove.

[0012] Through the above technical solution, the top cover is connected to the top of the hydraulic cylinder body by bolt threads, and the locking pin is engaged with the locking groove. This dual connection method not only ensures the firmness of the top cover connection, but also effectively prevents hydraulic oil leakage and the intrusion of external impurities, protecting the hydraulic oil and components inside the hydraulic cylinder and extending the service life of the hydraulic cylinder. When it is necessary to inspect or maintain the hydraulic cylinder, the bolts are first unscrewed, and the top cover is removed from the top of the hydraulic cylinder body. This allows for convenient inspection, repair, or replacement of parts inside the hydraulic cylinder, improving the convenience of inspection and maintenance.

[0013] As a further improvement to the above solution, the bottom end of the mounting platform contacts the top end of the base plate, and the bottom end of the base plate has a threaded hole with a screw inside. The base plate is threadedly connected to the bottom end of the mounting platform through the threaded hole at the bottom end.

[0014] Through the above technical solution, the mounting platform provides a stable installation foundation for the hydraulic cylinder body and other related components, ensuring the stability and reliability of the hydraulic cylinder during operation. The base plate further enhances the stability of the entire device. Through its connection with the mounting platform, the weight of the hydraulic cylinder is evenly distributed over a larger area, preventing the device from tipping over or swaying due to an unstable center of gravity. The base plate is threaded to the bottom of the mounting platform through a threaded hole at its bottom. This threaded connection method ensures a stable and reliable connection between the mounting platform and the base plate, and also facilitates adjusting the height of the mounting platform or replacing the mounting platform according to actual needs, further improving the flexibility of the entire hydraulic cylinder installation.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a transmission structure consisting of four clamping blocks connected by a transmission ring, a rotating rod, and a rotating handle to conveniently clamp and fix the hydraulic cylinder body. The rotating handle is simple and intuitive to operate; operators can clamp or release the hydraulic cylinder body by simply rotating the handle. This design significantly improves the efficiency of installing and removing the hydraulic cylinder on the mounting platform. Protective cotton is fixedly connected to the ends of the clamping blocks that are close to each other. When clamping the hydraulic cylinder body, the protective cotton acts as a buffer to prevent damage to the cylinder body and also increases friction, making the clamping more stable.

[0017] The top cover is connected to the top of the hydraulic cylinder body by bolts and threads, while the locking pin engages with the locking slot. This dual connection method ensures both the robustness of the top cover connection and ease of installation and disassembly. During installation, the locking pin engages with the locking slot to initially position the top cover, and then the bolts are tightened to complete the secure connection. During disassembly, the bolts are unscrewed first, and then the top cover can be easily removed, facilitating inspection or maintenance of the hydraulic cylinder's internal components.

[0018] The base plate is threaded to the bottom of the mounting platform via a threaded hole at its bottom. This threaded connection ensures a stable and reliable connection between the mounting platform and the base plate, and also facilitates adjusting the height of the mounting platform or replacing the mounting platform as needed, further improving the flexibility of the entire hydraulic cylinder installation.

[0019] This utility model uses the protective cotton on the clamping block to protect the hydraulic cylinder body when clamping it, preventing the surface of the hydraulic cylinder body from being scratched or squeezed and deformed, thus extending the service life of the hydraulic cylinder.

[0020] Four rotating handles are fitted with fixing plates, the bottom of which are fixedly connected to the top of the mounting platform. This structural design makes the rotating handles more stable during operation, preventing wobbling or deviation, thus ensuring the accuracy and stability of the clamping block in holding the hydraulic cylinder body.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0029] Please combine Figure 1-5 This embodiment of a conveniently installed hydraulic cylinder includes a hydraulic cylinder body 1, which is placed on the top of a mounting platform 7. The surface of the hydraulic cylinder body 1 is in contact with clamping blocks 14, and four clamping blocks 14 are provided. Protective cotton is fixedly connected to the ends of the four clamping blocks 14 that are close to each other, and transmission rings 13 are fixedly connected to the ends of the four clamping blocks 14 that are far apart from each other. Four transmission rings 13 are provided.

[0030] Four drive rings 13 are connected to rotating rods 12 at their far ends. There are four rotating rods 12, and a rotating handle 11 is fixedly connected to the far ends of the four rotating rods 12.

[0031] There are four rotating handles 11, and four fixing plates 10 are sleeved on the surface of the four rotating handles 11. The bottom of the four fixing plates 10 is fixedly connected to the top of the mounting platform 7.

[0032] The top end of the hydraulic cylinder body 1 contacts the bottom end of the top cover 2. The top end of the top cover 2 is threadedly connected to the top end of the hydraulic cylinder body 1 by bolts 3. Several bolts 3 are provided.

[0033] The top of the top cover 2 is fixedly connected to a locking post 5, and the top of the hydraulic cylinder body 1 is provided with a locking groove 6, and the surface of the locking post 5 is engaged with the inner wall of the locking groove 6.

[0034] The bottom of mounting platform 7 contacts the top of base plate 8.

[0035] The bottom end of the base plate 8 is provided with a threaded hole 9, and a screw is installed inside the threaded hole 9. The base plate 8 is threadedly connected to the bottom end of the mounting platform 7 through the threaded hole 9 at the bottom end.

[0036] The implementation principle of a conveniently installed hydraulic cylinder in this embodiment is as follows: First, the hydraulic cylinder body 1 is placed on the top of the mounting platform 7. Then, the operator rotates the four rotating handles 11, which drives the rotating rod 12 to rotate. The rotation of the rotating rod 12 is transmitted to the clamping blocks 14 through the transmission ring 13, causing the four clamping blocks 14 to move closer to each other until the protective cotton is in tight contact with the hydraulic cylinder body 1, thus firmly clamping the hydraulic cylinder body 1 onto the mounting platform 7. The locking pin 5 at the top of the top cover 2 is aligned with the locking groove 6 at the top of the hydraulic cylinder body 1, so that the locking pin 5 is inserted into the locking groove 6, thus initially positioning the top cover 2. Next, use several bolts 3 to thread the top of the top cover 2 to the top of the hydraulic cylinder body 1. Tighten the bolts 3 to complete the installation of the top cover 2. Then, thread the base plate 8 to the bottom of the mounting platform 7 through the threaded hole 9 at the bottom. Screw the screws into the threaded hole 9 to firmly connect the mounting platform 7 and the base plate 8 together, thus completing the entire installation process of the hydraulic cylinder. When maintenance or repair of the hydraulic cylinder is required, first unscrew the bolts 3 and remove the top cover 2 from the top of the hydraulic cylinder body 1. Then, rotate the handle 11 in the opposite direction to release the clamping block 14 from the hydraulic cylinder body 1. This allows the hydraulic cylinder body 1 to be easily removed from the mounting platform 7 for internal inspection, repair, or replacement of parts.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
