2results about How to "Will not reverse" patented technology

The utility model relates to the technical field of feeding machines, in particular to a universal feeding machine structure suitable for various materials, which comprises a base, a connecting arm, a connecting disc and a feeding hopper, and the top surface of the base is fixedly connected with the bottom surface of the connecting arm. Then the rotary knob is rotated again, the linkage block is driven to rotate reversely through the rotary knob, the linkage block drives the ratchet wheel to rotate together through the rotating ring during rotation, the ratchet wheel is limited in a one-way mode through the pawl, and it can be guaranteed that the linkage block cannot rotate reversely when the first feeding pipe and the second feeding pipe are switched back and forth; the pulling block can be pulled back, the pawl is driven by the pulling block to not limit the ratchet wheel any more, the linkage block can be rotated reversely to switch the first feeding pipe and the second feeding pipe, and the feeding hopper can be matched with the control part to switch the types of fed raw materials at will so as to replace the feeding pipes at any time.

The application relates to the field of stainless steel pipe connection, and discloses a stainless steel pipe connection sealing mechanism, which comprises two stainless steel pipes and a connecting head arranged between the two stainless steel pipes. Inner thread assembly grooves are arranged on the left and right sides of the connecting head. A same communication hole is arranged on the inner wall of the side, where the two inner thread assembly grooves are close to each other. The ends, where the two stainless steel pipes are close to each other, respectively penetrate through the corresponding inner thread assembly grooves and extend into the communication hole. Bearings are fixedly sleeved on the two stainless steel pipes. The outer rings of the two bearings are fixedly sleeved with outer thread sleeves. The application has the following advantages and effects: multiple sealing between the two stainless steel pipes and the connecting head can be realized, the sealing performance of the connection part of the two stainless steel pipes can be ensured through the synergistic effect of multiple sealing, the omnibearing sealing effect is realized, and the application is suitable for fluid conveying scenes with strict sealing requirements.
