Description

Technical Field

[0001] This utility model relates to the field of power assist device technology, and in particular to a push-pull power assist device for a planetary gearbox. Background Technology

[0002] Big data and cloud computing have ushered in the intelligent era of the internet. Against this backdrop, the internet information age is developing rapidly, and various industries generate massive amounts of data during their development. This has led to ever-increasing demands for transmission speed, processing efficiency, storage capacity, and high-performance computing in the face of such massive data volumes. In communication equipment, individual modules need to be inserted into the chassis and connected to the backplane, with the two relying on connectors. Currently, the connection between the single-board module and the backplane is achieved by inserting the single board into the chassis using an assisted insertion and removal device. When it is necessary to replace, maintain, or upgrade the single-board module, it is also necessary to remove it from the chassis using this assisted insertion and removal device.

[0003] Application CN202321092589.3 discloses a planetary gearbox structure push-pull power-assist device that maximizes the stroke and output torque of the turntable body within a specified support plate space. It employs a planetary gearbox structure and an asymmetrical turntable body tooth profile design. Planetary gearboxes offer advantages such as high repeatability, high precision, compact structure, high transmission efficiency, and large output torque. Placing the planetary gearbox structure at the input end increases torque, which is then transmitted to the output end via a single-stage gear set, enabling the overall push-pull power-assist device to achieve high output torque and long stroke. However, the gear assembly in this patent is located inside the support plate, which is connected to the outer shell using multiple screws. This necessitates the use of wrenches, screwdrivers, and other tools to loosen each screw during installation and disassembly, which is time-consuming, laborious, and impractical.

The inner surface of the fixed box 7 is slidably connected to the inclined block 8, and the outer surface of the inclined block 8 is fixedly connected to the first spring 9. The inner surface of the fixed box 7 is slidably connected to the sliding rod 10. The lower end of the sliding rod 10 is fixedly connected to the wedge block 11, and the upper end of the sliding rod 10 is fixedly connected to the limiting plate 12. The inner surface of the limiting plate 12 is threadedly connected to the threaded column 13. The lower end of the threaded column 13 is fixedly connected to the limiting round block 14, and the upper end of the threaded column 13 is fixedly connected to the limiting block 15. The lower surface of the limiting block 15 is fixedly connected to the second spring 16. The outer surface of the threaded column 13... The upper surface of the fixed box 7 is slidably connected to the hexagonal sleeve 17. The upper surface of the fixed box 7 is provided with a slot 19. The inner surface of the slot 19 is adapted to the pin 18 to facilitate the limiting of the threaded pin 13. The inner surface of the slot 5 is adapted to the inclined insert 8 to facilitate the fixing of the cover 3. The upper surface of the cover 3 is fixedly connected to the fixed box 7. The outer surface of the inclined insert 8 is slidably connected to the fixed box 7. The outer surface of the wedge block 11 is slidably connected to the fixed box 7.

[0027] Working principle: When lubrication of the gear assembly inside the main body shell 1 is required, simply pull the hexagonal sleeve 17 upward to drive the pin 18 out of the slot 19. Then, rotate the hexagonal sleeve 17. Under the limiting action of the limiting block 15, the threaded column 13 will rotate, and the second spring 16 will be compressed. This will cause the limiting plate 12 to slide along the inclined surface of the inclined insert 8 via the slide rod 10, thereby causing the corresponding inclined inserts 8 on both sides to move towards each other and compress the first spring 9, thus causing the inclined inserts 8 to disengage from the slot 5. Then, slide the cover 3 upward along the buckle seat 2 to expose the gear assembly inside the main body shell 1. Then, inject lubricating oil into the main body shell 1 to complete the lubrication operation. Then, align the positioning groove 4 on the cover 3 with the buckle seat 2 and snap it in. When the slot 5 on the buckle seat 2 corresponds to the inclined insert 8 in the retracted state, pull up the hexagonal sleeve 17 again and rotate it to move the limiting plate 12 upward. At this time, under the action of the rebound force of the first spring 9, the inclined insert 8 will insert into the corresponding slot 5, thereby completing the fixation of the cover 3. It is simple and convenient.
