The embodiment of the application discloses a cross column processing device and a processing method. The device comprises a jig support plate, a door type suspension support frame, a vertical pressing jack and an angle adjusting jack. In the process of preparing the cross column, the H-shaped steel can be arranged on the jig support plate, the T-shaped steel is arranged on the H-shaped steel, the vertical section of the T-shaped steel is arranged on the horizontal section of the H-shaped steel, then the vertical pressing jack is started, the vertical section of the T-shaped steel can be closely combined with the horizontal section of the H-shaped steel, the gap between the vertical section of the T-shaped steel and the horizontal section of the H-shaped steel is greatly reduced, and the angle adjusting jack can be started. The angle adjusting jack can drive the T-shaped steel to rotate relative to the H-shaped steel, that is, the setting angle of the T-shaped steel can be adjusted. The cross column processed by the cross column processing device provided by the embodiment of the application has higher precision and more excellent performance, and the preparation efficiency of the cross column can be improved.

The utility model relates to the technical field of balance door accessories, and provides a self-locking support arm connecting structure and a balance door, a rectangular hole and a screw hole are arranged at the support arm connecting position of an upper transverse frame and a lower transverse frame of a door leaf, the self-locking support arm connecting structure comprises an L-shaped support arm main body, the shorter wing of the L-shaped support arm main body is a main shaft sleeve, and the lower wing of the L-shaped support arm main body is a main shaft sleeve. A rotating shaft accommodating space is arranged at the longer wing end part of the L-shaped support arm main body, and rotating shaft mounting holes are formed in an upper transverse plate and a lower transverse plate of the L-shaped support arm main body; the special-shaped shaft sleeve structure comprises a shaft sleeve main body matched with the rotating shaft accommodating space, a door leaf connecting part integrally formed with the shaft sleeve main body, and a clamping block arranged on the back surface of the shaft sleeve main body; the rotating shaft penetrates through the rotating shaft mounting hole and the shaft sleeve main body. According to the technical scheme, the connecting position is not prone to being damaged, meanwhile, the clamping block can bear the weight of the door leaf, and when the door leaf droops due to the gravity of the door leaf, self-locking is achieved, namely the door leaf and the clamping block are connected more firmly, and the connecting firmness of the supporting arm and the door leaf is higher.

The utility model relates to a valve, specifically disclose a unloading valve at least including valve body, valve rod, diaphragm mechanism, auxiliary spring, adjusting cylinder, pressure regulating spring, top plug and adjusting plug. Among them, the lower diaphragm fixed base includes the horizontal extension diaphragm fixed section one and the axial extension valve body connecting section, the diaphragm fixed section one and valve body connecting section between smooth transition connection, the upper end of valve body is provided with the outer ring groove of with the inner chamber of valve body connecting section adaptation, the axial height of outer ring groove with the axial height of valve body connecting section adaptation, the radial depth of outer ring groove with the thickness of lower diaphragm fixed base adaptation, valve body connecting section is set up on outer ring groove and is fixed through welding. In the utility model, based on the cooperation between valve body connecting section and outer ring groove on the valve body of lower diaphragm fixed base, a longer welding lap joint surface is formed, which has higher reliability under high pressure environment, and the service life of the unloading valve is longer.

The utility model provides a magnetic connecting device and an electronic equipment support. The magnetic connecting device comprises a magnetic assembly and a fixing assembly. The magnetic assembly is used for providing magnetic attraction force for attracting the magnetically-attractable equipment. The fixing assembly is used for supporting the magnetically-attractable device. The magnetic connecting device has a first state and a second state, in the first state, the magnetic attraction force generated by the magnetic assembly to the magnetically-attractable equipment is F1, in the second state, the magnetic attraction force generated by the magnetic assembly to the magnetically-attractable equipment is F2, and F1 is larger than F2, and in the switching process of the magnetic connecting device between the first state and the second state, F2 is larger than F2; the fixing assembly is configured to be suitable for providing supporting force opposite to the gravity direction for the magnetic attraction equipment. When the magnetic force can be reduced, the fixing assembly still keeps the supporting effect on the magnetically-attractable equipment, so that the magnetic connecting device is favorable for avoiding the falling phenomenon caused by reduction of the magnetic force, and has higher connecting reliability.
