4results about How to "Improve buffer protection effect" patented technology

The utility model discloses a kind of high-efficiency vacuumizing equipment, belong to vacuumizing equipment technical field, including fuselage, and four dampers for anti-shock protection are arranged below fuselage, the bottom end of four dampers is connected with mounting seat, the right side of fuselage is equipped with back cover, the left side of fuselage is equipped with front cover, and the top of front cover is provided with two air inlet and outlet seats, plug is installed in the inside of two air inlet and outlet seats and penetrates, the top of plug is connected with pipeline, the bottom of fuselage is rotatably installed with two support rods, and the bottom end of two support rods is rotatably connected with moving block. The high-efficiency vacuumizing equipment is provided with damper, mounting seat is connected with four dampers at the bottom of fuselage, the buffering protection performance of fuselage itself can be increased by four dampers, mechanical wear is reduced, key components are protected, resonance between fuselage and pipeline due to rigid connection is avoided, and the service life of vacuumizing equipment is improved.

This utility model relates to the field of wireless earphone technology, specifically to a quick-plug wireless earphone charging PIN pin structure. It mainly includes an outer cavity, with a piston cylinder connected to the inner side of the outer cavity, and a PIN pin body slidably connected to the inner side of the piston cylinder. The insertion / removal protection component includes a trapezoidal retaining ring, with a guide rod disposed on the inner side of the trapezoidal retaining ring, and a PIN pin tip disposed at the front end of the guide rod. The installation adjustment component includes an installation ring. This quick-plug wireless earphone charging PIN pin structure achieves unidirectional position adjustment by setting a foolproof structure on the inner side of the PIN pin body. The elastic connection of the conductive spring improves the buffer protection performance and increases the contact range. The elastic compression also ensures a tighter contact during charging. The dispersed PIN pin tips at the end of the PIN pin body increase the probability of contact with the earphone's metal contacts, reduce the probability of poor charging contact, and improve the efficiency of the PIN pin structure.

The utility model belongs to technical field, concretely relates to a combined crash barrier, including first barrier board and second barrier board, the size of first barrier board and second barrier board is same, and the lower extreme of first barrier board and second barrier board is fixedly connected with a plurality of support legs respectively, the lower extreme of support leg is fixedly connected with support block, support block is provided with a plurality of threaded holes, first barrier board and second barrier board are provided with combination mechanism, first barrier board and second barrier board are provided with buffer crashproof mechanism. The utility model discloses through the lower pressure of the first barrier board and the second barrier board of the pressure block, the lower end of the first barrier board and the second barrier board is tightly attached to the top block, the front slide bar is connected with the front lug plate sliding, the rear slide bar is connected with the rear lug plate sliding, then the lower end of the front slide bar and the rear slide bar is limited by the nut, thereby the lower end of the front slide bar and the rear slide bar is fixedly limited, avoids the front slide bar and the rear slide bar to separate, thereby the effect of the loading and unloading of the first barrier board and the second barrier board is convenient to reach.

The electromagnet internally provided with the buffering function comprises a supporting guide seat, a limiting clamping groove is formed in the position, close to the front portion, of the inner end face of the supporting guide seat, and positioning clamping plates are symmetrically arranged at the bottom of the side end face of the supporting guide seat. By arranging the buffer device, when the electromagnet is subjected to buffer protection, the front and rear groups of buffer spring shafts can firstly elastically buffer the protection chuck, the threaded rotating plate and the iron core, so that the protection chuck, the threaded rotating plate and the iron core are prevented from being in rigid contact with the sealing clamping plate or the electromagnet sleeve shell; and meanwhile, after the buffering spring shaft conducts elastic buffering, the buffering guide shaft can conduct rigid limiting on the protection chuck, the threaded rotating plate and the iron core, displacement of the protection chuck, the threaded rotating plate and the iron core is prevented from being over-limited, and the buffering protection performance of the interior and the exterior of the electromagnet can be effectively improved through the dual protection structure.
