Description

Technical Field

[0001] This utility model relates to the field of gravity balance cylinder technology, specifically a gravity balance cylinder based on an air film. Background Technology

[0002] A gravity balancing cylinder based on a gas film is a device that uses the gas film principle to achieve gravity balance. Its core principle is to form a stable gas film inside the cylinder, thereby reducing or eliminating the influence of gravity on moving parts and ensuring the stability and accuracy of the equipment. It is usually composed of a cylinder barrel, piston, air passage sleeve, throttle orifice, and ball joint.

[0003] To facilitate the maintenance and upkeep of the gravity balancing cylinder, its top and bottom covers are usually detachably connected by a connecting rod and secured with multiple nuts on the threads at the top of the connecting rod. Since the bolts require tools to be turned multiple times for disassembly and assembly, the disassembly and assembly process is cumbersome. Therefore, to address the above issues, a gravity balancing cylinder based on an air film is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a gravity-balanced cylinder based on an air film to solve the problem of cumbersome disassembly and assembly process during internal maintenance of the cylinder.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gravity-balancing cylinder based on a film gas includes a housing, a top cover, a piston rod, a connecting rod, and a bottom cover. The bottom cover is fixedly connected to the bottom of the housing, and several connecting rods are fixedly connected to the top of the bottom cover. The top cover, with its two sides recessed, is tightly fitted to the top of the housing. The piston rod passes through the middle of the top cover. A disassembly assembly is provided on one side of the top cover. The disassembly assembly includes a connecting plate, a guide post, a movable plate, a locking block, an electromagnet, a magnetic block, and a spring. The two sides of the housing are fixedly connected to the connecting plates with recessed surfaces. The guide post is fixedly connected to the recesses of the connecting plates. The movable plate, with two protrusions at its bottom, is slidably connected to the outer side of the guide post. A locking block is fixedly connected to one side of the movable plate, and an electromagnet is fixedly connected to one side of the locking block. Holes are opened on both sides inside the top cover, and several magnetic blocks are provided inside the top cover.

[0007] Preferably, a spring is provided on the outer side of the guide post, and the spring is disposed between the inner wall of the recess of the connecting plate and the protrusion at the bottom of the moving plate.

[0008] Preferably, a rubber layer is fixedly connected to both the inner wall of the hole and one side of the movable plate. The rubber layer on one side of the movable plate penetrates the locking block and fits tightly against the top cover. The rubber layer at the inner wall of the hole fits tightly against the electromagnet.

[0009] Preferably, both the card block and the electromagnet are inserted into the hole, and a handle is fixedly connected to one side of the movable plate.

[0010] Preferably, the bottom of the top cover has several limiting grooves, and the limiting grooves are tightly fitted to one end of the connecting rod.

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

[0012] In this invention, the user controls the movement of the movable plate by energizing or de-energizing the electromagnet through a housing, top cover, piston rod, connecting rod, disassembly / assembly assembly, connecting plate, guide post, movable plate, locking block, electromagnet, magnetic block, hole, and bottom cover.

[0021] Please see Figure 1-5 This utility model provides a technical solution:

[0022] A gravity-balancing cylinder based on a film-supported structure includes a housing 1, a top cover 2, a piston rod 3, connecting rods 4, and a bottom cover 9. The bottom cover 9 is fixedly connected to the bottom of the housing 1, and several connecting rods 4 are fixedly connected to the top of the bottom cover 9. The top cover 2, with recessed sides, is tightly fitted to the top of the housing 1. The piston rod 3 passes through the middle of the top cover 2. A disassembly assembly 5 is provided on one side of the top cover 2. The disassembly assembly 5 includes a connecting plate 51, a guide post 52, a moving plate 53, a locking block 54, an electromagnet 55, a magnetic block 56, and a spring 57. The concave surfaces of the connecting rods 4 are fixedly connected to the sides of the housing 1. A connecting plate 51 with a recess is provided, and a guide post 52 is fixedly connected to the recess of the connecting plate 51. A movable plate 53 with two protrusions at the bottom is slidably connected to the outside of the guide post 52. A locking block 54 is fixedly connected to one side of the movable plate 53, and an electromagnet 55 is fixedly connected to one side of the locking block 54. Holes 10 are opened on both sides inside the top cover 2, and several magnetic blocks 56 are provided inside the top cover 2. The disassembly and assembly components 5 are provided to facilitate the disassembly and assembly of the top cover 2. Compared with the existing technology that uses tools to repeatedly turn the nuts for disassembly and assembly, this structure makes the disassembly and assembly process more convenient and faster.

[0023] A spring 57 is provided on the outside of the guide post 52. The spring 57 is located between the inner wall of the recess of the connecting plate 51 and the bottom protrusion of the moving plate 53, which facilitates the automatic rebound of the moving plate 53. A rubber layer 7 is fixedly connected to the inner wall of the hole 10 and one side of the moving plate 53. The rubber layer 7 on one side of the moving plate 53 passes through the locking block 54 and fits tightly against the top cover 2. The rubber layer 7 on the inner wall of the hole 10 fits tightly against the electromagnet 55, so that the surfaces of the moving plate 53 and the electromagnet 55 are not easily damaged when subjected to magnetic attraction. The locking block 54 and the electromagnet 55 are inserted into the hole 10. A handle 6 is fixedly connected to one side of the moving plate 53, which facilitates the movement of the locking block 54. Several limiting grooves 8 are opened at the bottom of the top cover 2. The limiting grooves 8 fit tightly against one end of the connecting rod 4, which facilitates the positioning of the top cover 2 during installation.

[0024] Workflow: During operation, the equipment is powered by an external power source. When using the gravity balancing cylinder based on an air film, it must first be installed, ensuring its installation position is stable and secure to prevent vibration or loosening during operation. Simultaneously, a suitable installation method should be selected according to actual needs, such as horizontal or vertical installation. After installation, the piston rod 3 of the cylinder can push the object horizontally. To ensure the long-term stable operation of the balancing cylinder, regular maintenance is essential. During maintenance, the top cover 2 needs to be disassembled. The user first disconnects the power to the electromagnet 55, eliminating the magnetic attraction between the electromagnet 55 and the magnetic block 56 inside the top cover 2. At this point, the handle 6 can be moved outwards, causing the moving plate 53 to move in the same direction. The protrusion at the bottom of the moving plate 53 moves outside the guide post 52, compressing the spring 57, simultaneously causing the locking block 54 and the electromagnet 55 to gradually move away from the top cover. 2. The holes 10 on both sides allow the user to hold the top cover 2 and move it upwards after the electromagnet 55 is completely removed. This allows the limiting groove 8 at the bottom of the top cover 2 to gradually move away from one end of the connecting rod 4. The top cover 2 is then moved upwards until it is removed. At this point, the piston rod 3 can be removed from the housing 1 for repair or maintenance. During installation, the top cover 2 is inserted through one end of the piston rod 3 until the connecting rod 4 is inserted into the limiting groove 8. The top cover 2 and the connecting plate 51 are tightly fitted together. The handle 6 is released, and under the action of the spring 57, the locking block 54 and the electromagnet 55 are pushed into the holes 10 of the top cover 2. The electromagnet 55 is energized, so that a magnetic attraction is generated between the electromagnet 55 and the magnetic block 56. The locking block 54 is magnetically fixed after insertion, thereby fixing the installed top cover 2. The disassembly and assembly components 5 facilitate the disassembly and assembly of the top cover 2. Compared with the existing technology that uses tools to repeatedly turn the nuts for disassembly and assembly, this structure makes the disassembly and assembly process more convenient and faster.
