4results about How to "Prevent automatic fall off" patented technology

The utility model provides self-cleaning equipment of a cleaning device of mining belt type conveying equipment, and belongs to the technical field of mining mechanical engineering. Comprising a fixing frame, a servo motor installed on the outer side of the fixing frame in a matched mode, a driving roller fixedly connected to output of the servo motor through a fixing coupler, a conveying belt arranged on the outer surface of the driving roller in a sleeving mode, a supporting roller arranged on the inner surface of the other end of the conveying belt in a sleeving mode, and an installation block fixedly connected to the outer surface of the fixing frame. And the scraper is arranged on the inner side of the mounting block and is matched with the conveying belt for use. Through cooperation of the conveying equipment body and the cleaning mechanism, operation and stop of the cleaning assembly can be automatically controlled according to the speed of the conveying belt under the condition that an additional driving source is not additionally arranged, unnecessary cleaning of the scraper when impurities can automatically fall off is avoided, abrasion to the surface of the scraper is reduced, and meanwhile the cleaning efficiency of the scraper is improved. And the effect that mine material transportation work is conducted stably is ensured.

This invention provides a network controller and network control method. The structure includes: a locking block, an insulating box, a control body, a power supply slot, a data connection structure, and a heat dissipation end. The locking block is fixed to the left and right sides of the insulating box, which covers the outside of the control body. The power supply slot and the data connection structure penetrate the insulating box and form an integral part with the control body. The heat dissipation end is located at the upper end of the control body. This invention improves the data connection structure by using a locking ring to firmly connect the flat plate to the surface of the insulating box. Then, a central restraining rod of a reinforcing frame is embedded in the center of the data cable spool connector for restraint. Simultaneously, the adjusting parts of the reinforcing frame are clamped symmetrically, ensuring a secure connection to the data cable spool connector in conjunction with the central restraining rod. This prevents automatic detachment during long-term use, facilitating disassembly and assembly, and improving the actual stability of the network controller.

This invention provides a smart insulin pen needle disposal box with a reminder function. Its structure includes: an anti-slip plate, a main box, a charging slot, a positioning buckle, a groove, a smart reminder structure, and a protective cover. The anti-slip plate is parallel to the lower end of the main box, and the side of the main box is integrated with the charging slot and positioning buckle. The groove is opened inside the main box and defines the position of the smart reminder structure. With the improved smart reminder structure, when the trigger structure is electrically connected vertically to the inside of the main box, after the pen needle is inserted into the pushing structure, the pushing structure slides down, thereby pressing down the control block in the center groove of the parallel plate. This pressing down of the control block, combined with the power slot, illuminates the reminder light strip on the vertical edge of the sleeve, achieving the effect of reminding the needle to be inserted securely. If not securely inserted, the reminder light strip will not illuminate, thus improving the usability of the disposal box and meeting the requirements of a reminder function, further enhancing the safety factor of insulin pen needle recycling.
