5results 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.

The utility model relates to the technical field of access control, in particular to a multifunctional special access control for a community, which comprises an access control body, a protective structure is mounted on the front side of the bottom of the access control body and comprises a protective frame, the front side of the bottom end of the access control body is detachably connected with the protective frame, and the front side of the protective frame is detachably connected with a dust cover. The dust cover is made of non-woven fabric, an elastic band is sewn in the closing-up position of the dust cover, a clamping groove is formed in the protection frame, the dust cover and the clamping groove are clamped, clamping plates are rotationally connected to the top end and the bottom end of the protection frame, rotating shafts are fixedly connected to the bottom ends of the clamping plates, a fixing shaft is fixedly connected into the protection frame, and the fixing shaft is fixedly connected with the dust cover. The rotating shaft is rotationally connected with the fixed shaft, and a torsional spring is fixedly connected between the rotating shaft and the fixed shaft; the horn mouth of the entrance guard can be protected, so that dust can be prevented from entering the horn mouth to cause blockage and influence use.

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.

The utility model relates to a lamp tube clamping type warmer, including the shell, is provided with first heating area and second heating area on the shell, and first heating area and second heating area are communicated in the shell inside, first heating area and second heating area have different radiation direction, the reflector board is located in the inside of first heating area, the lamp tube is located in the inside of first heating area, the shell inside is provided with the mounting plate who penetrates first heating area and second heating area, the outside of mounting plate is equipped with the card and carries out the constraint to the lamp tube in axial direction, the utility model has the advantages of: through the design that the mounting plate is radially restrained to the lamp tube, the card is axially restrained, the installation stability of the lamp tube and mounting plate is guaranteed, simultaneously, the card and mounting plate are all simple sheet body structure, and production assembly flow is simple, and production cost is reduced, and the design of limiting buckle and limiting male prevents the card from falling off automatically, and the connection stability of card and lamp tube, mounting plate is ensured.
