Description

Technical Field

[0001] This utility model relates to the field of pneumatic lifting mechanism technology, and specifically discloses a detachable pneumatic lifting mechanism. Background Technology

[0002] In industrial production, logistics and transportation, equipment installation and other fields, pneumatic lifting mechanisms are widely used to lift, position and adjust the posture of heavy objects due to their advantages such as fast response, convenient operation and cleanliness. At present, the connection between the core component of pneumatic lifting mechanisms and the mounting base plate is mostly a fixed structure, such as direct fastening with bolts, welding, or one-piece casting design. However, when the pneumatic lifting mechanism malfunctions and requires repair or replacement of parts due to direct bolt fastening, the fixed connection makes disassembling the cylinder body from the mounting plate extremely cumbersome. Repeated disassembly damages the threaded holes, affecting installation stability. Welded fixing or integrated structures further prevent individual component disassembly. Once a component fails, the entire lifting mechanism often needs to be replaced, significantly increasing maintenance costs and wasting resources. Therefore, a detachable pneumatic lifting mechanism is needed to solve these problems. Utility Model Content

[0003] This utility model proposes a detachable pneumatic lifting mechanism. During installation, the detachable pneumatic lifting mechanism is automatically guided and positioned by the inclined surface of the insert plate, and can be locked by rotating the locking sleeve, which greatly simplifies the steps and reduces labor and time costs. During disassembly, it is only necessary to rotate the locking sleeve in the opposite direction and then pull the vertical plate.

[0004] This utility model is implemented as follows: a detachable pneumatic lifting mechanism includes a cylinder body and a mounting base plate. A locking mechanism is provided between the cylinder body and the mounting base plate. The locking mechanism includes a support plate located below the cylinder body. A rectangular block is fixedly connected to the lower end of the support plate. An installation groove is opened at the lower end of the rectangular block. Multiple insert plates are slidably connected through the outer wall of the rectangular block. A vertical plate is fixedly connected to the outer wall of each of the multiple insert plates. A spring is fixedly connected between the vertical plate and the rectangular block. An externally threaded post is fixedly connected to the upper end of the mounting base plate. A locking sleeve is threadedly connected to the outer wall of the externally threaded post. An auxiliary block is fixedly connected to the upper end of the externally threaded post. Multiple insertion holes are opened on the outer wall of the auxiliary block. An arc-shaped groove is opened at the lower end of each of the multiple insert plates.

[0005] As a preferred embodiment of the detachable pneumatic lifting mechanism of this utility model, the outer wall of the vertical plate is rotatably connected to a support shaft, and the outer wall of the support shaft is fixedly connected to an eccentric rod.

[0006] As a preferred embodiment of the detachable pneumatic lifting mechanism of this utility model, two symmetrically distributed connecting plates are fixedly connected between the lower end of the cylinder body and the upper end of the support plate.

[0007] As a preferred embodiment of the detachable pneumatic lifting mechanism of this utility model, the plurality of insert plates are all inclined at one end of the mounting groove.

[0008] As a preferred embodiment of the detachable pneumatic lifting mechanism of this utility model, the curvature of the plurality of arc-shaped grooves is adapted to the curvature of the locking sleeve.

[0009] As a preferred embodiment of the detachable pneumatic lifting mechanism of this utility model, the size of the mounting groove is adapted to the size of the auxiliary block.

[0010] As a preferred embodiment of the detachable pneumatic lifting mechanism of this utility model, a limit ring is fixedly connected to the outer wall of the external threaded column.

[0011] The beneficial effects of this utility model are: During installation, the inclined surface of the insert plate guides the auxiliary block to automatically push the insert plate outward as it is embedded in the installation slot. Initial positioning can be completed without manual operation of the insert plate. Afterward, only the locking sleeve needs to be rotated to achieve a firm lock. Compared with the cumbersome alignment and tightening operation of traditional bolt fastening, the installation steps are greatly simplified, reducing labor costs and assembly time. Disassembly is flexible and quick. During disassembly, simply rotate the locking sleeve in the opposite direction to disengage it from the arc groove, and then pull the vertical plate to disengage the insert plate from the insertion hole. There is no need to deal with problems such as bolt corrosion, stripped threads, or welding disassembly, avoiding damage to components such as the cylinder body and mounting base plate, significantly improving maintenance or component replacement efficiency and reducing equipment downtime.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4 A detachable pneumatic lifting mechanism includes a cylinder body 1 and a mounting base plate 10. A locking mechanism is provided between the cylinder body 1 and the mounting base plate 10. The locking mechanism includes a support plate 3 located below the cylinder body 1. A rectangular block 4 is fixedly connected to the lower end of the support plate 3. An installation groove 17 is opened at the lower end of the rectangular block 4. Multiple insert plates 5 are slidably connected through the outer wall of the rectangular block 4. A vertical plate 6 is fixedly connected to the outer wall of each of the multiple insert plates 5. A spring 7 is fixedly connected between the vertical plate 6 and the rectangular block 4. An external threaded post 11 is fixedly connected to the upper end of the mounting base plate 10. A locking sleeve 12 is threadedly connected to the outer wall of the external threaded post 11. An auxiliary block 13 is fixedly connected to the upper end of the external threaded post 11. Multiple insertion holes 14 are opened on the outer wall of the auxiliary block 13. An arc-shaped groove 15 is opened at the lower end of each of the multiple insert plates 5.

[0020] In this embodiment: During installation, the rectangular block 4 connected to the support plate 3 below the cylinder body 1 is aligned with the auxiliary block 13 at the upper end of the mounting base plate 10, so that the auxiliary block 13 is embedded in the mounting groove 17 of the rectangular block 4. During the process, the auxiliary block 13 presses the inclined surface of the insert plate 5, causing the insert plate 5 to move the vertical plate 6 outward and compress the spring 7. When the auxiliary block 13 is fully embedded, the spring 7 returns to its original position and pushes the insert plate 5 into the insertion hole 14 of the auxiliary block 13 to complete the initial locking. Then, the locking sleeve 12 on the external threaded column 11 is rotated to move it upward until the locking sleeve 12 fits with the arc groove 15 of the insert plate 5 to achieve a firm lock. During disassembly, the locking sleeve 12 is rotated in the opposite direction to move it downward and disengage it from the arc groove 15. The vertical plate 6 is pulled to move the insert plate 5 out of the insertion hole 14, and the cylinder body 1 can be lifted to separate the rectangular block 4 from the auxiliary block 13, thus completing the disassembly.

[0021] As a technical optimization of this utility model, the outer wall of the vertical plate 6 is rotatably connected to a support shaft 16, and the outer wall of the support shaft 16 is fixedly connected to an eccentric rod 8.

[0022] In this embodiment, the outer wall of the vertical plate 6 is rotatably connected to the eccentric rod 8 via the support shaft 16. The purpose of this is to utilize the eccentric structural characteristics of the eccentric rod 8 to provide a force-saving fulcrum for pulling the vertical plate 6. When the mechanism needs to be disassembled, the insert plate 5 is moved by pulling it with the eccentric rod 8, and the eccentric rod 8 is rotated so that one side of the eccentric rod 8 abuts against the outer wall of the support plate 3. At this time, one side of the insert plate 5 is completely disengaged from the insertion hole 14.

[0023] As a technical optimization of this utility model, two symmetrically distributed connecting plates 2 are fixedly connected between the lower end of the cylinder body 1 and the upper end of the support plate 3.

[0024] In this embodiment, the connection plate 2 can enhance the stability and force balance of the connection between the cylinder body 1 and the support plate 3.

[0025] As a technical optimization of this utility model, the multiple insert plates 5 are all set with inclined surfaces at one end of the mounting groove 17.

[0026] In this embodiment: with the guidance of the inclined surface, the vertical pressure is converted into a lateral force that pushes the insert plate 5 to slide outward, so that the insert plate 5 automatically compresses the spring 7 and retracts, allowing the auxiliary block 13 to be smoothly embedded into the mounting groove 17 without manual operation.

[0027] As a technical optimization of this utility model, the curvature of the multiple arc grooves 15 is adapted to the curvature of the locking sleeve 12.

[0028] In this embodiment, the curvature of the multiple arc grooves 15 is adapted to the curvature of the locking sleeve 12, so that the locking sleeve 12 and the multiple arc grooves 15 can fit tightly together, thereby enhancing the locking effect of the insert plate 5.

[0029] As a technical optimization of this utility model, the size of the mounting groove 17 is adapted to the size of the auxiliary block 13.

[0030] In this embodiment, the size of the mounting groove 17 is adapted to the size of the auxiliary block 13, so as to achieve precise positioning of the cylinder body 1 and the mounting base plate 10, laying the foundation for the reliable operation of the subsequent locking mechanism.

[0031] As a technical optimization of this utility model, the outer wall of the external threaded column 11 is fixedly connected with a limiting ring 9.

[0032] In this embodiment: the limiting ring 9 can prevent the locking sleeve 12 from disengaging from the external threaded post 11.

[0033] The working principle and usage process of this utility model are as follows: When the detachable pneumatic lifting mechanism is working, during the installation stage, first align the rectangular block 4 connected to the support plate 3 below the cylinder body 1 with the auxiliary block 13 at the top of the external threaded column 11 on the upper end of the mounting base plate 10. Since the size of the mounting groove 17 matches the size of the auxiliary block 13, precise positioning can be achieved. Press down the rectangular block 4 to make the auxiliary block 13 embed into the mounting groove 17. During the process, the auxiliary block 13 squeezes the inclined surface of the insert plate 5 located at one end of the mounting groove 17. The inclined surface converts the vertical pressure into a horizontal force, pushing the insert plate 5 to move the vertical plate 6 outward and compressing the spring 7. After the auxiliary block 13 is fully embedded, the spring 7 returns to its original position and pushes the insert plate 5 to insert into the auxiliary block. The insertion hole 14 of 13 is initially locked. Then, the locking sleeve 12 connected to the threaded outer wall of the external threaded column 11 is rotated to move it upward. Since the arc of the arc groove 15 matches the arc of the locking sleeve 12, the locking sleeve 12 and the arc groove 15 fit tightly to achieve a firm lock. In the disassembly stage, the locking sleeve 12 is rotated in the opposite direction to move it downward and get away from the arc groove 15. The eccentric rod 8 connected to the support shaft 16 on the outer wall of the vertical plate 6 (using the eccentric structure to provide a force-saving fulcrum) is used to pull the insertion plate 5 to move. The eccentric rod 8 is rotated so that one side of it abuts against the outer wall of the support plate 3 to keep the insertion plate 5 out of the insertion hole 14. Finally, the cylinder body 1 is lifted to separate the rectangular block 4 from the auxiliary block 13, completing the entire disassembly process.
