The present application relates to the technical field of auxiliary structure of cubic press, in particular to a temperature control device of cubic press, which is applied to cubic press, and the cubic press comprises six top hammers, each of which is provided with small and large pads, and a steel ring is detachably sleeved on the top hammer, the small and large pads and the top hammer; the temperature control device of cubic press comprises a cooling liquid pipe, each top hammer is provided with a cooling liquid pipe, both ends of the cooling liquid pipe pass through the small pad, and the cooling liquid pipe is detachably arranged on the steel ring, the cooling liquid pipe is configured to receive external cold liquid, thereby breaking through the heat transfer bottleneck of traditional indirect cooling of steel ring, so that the heat of the top hammer can be directly radiated through the cooling liquid pipe, while significantly reducing the interface thermal resistance and material thermal conductivity loss in the heat conduction path, the temperature stability of the superhard material synthesis process is ensured, and the synthesis efficiency and product quality are improved.

The application discloses a mortise cover plate type nested assembly type beam column connecting joint, which comprises a column assembly, a beam assembly and a connecting piece. The column assembly comprises an upper steel column, a lower steel column and a box-shaped bracket with an embedded bolt pipeline; the beam assembly comprises a horizontal I-shaped steel beam and a box-shaped accessory with an embedded bolt pipeline; and the connecting piece comprises a mortise cover plate and high-strength bolts, all the accessories are welded in a factory. When being installed, the box-shaped accessory with the embedded bolt pipeline is placed into the box-shaped bracket with the embedded bolt pipeline along the horizontal direction, and the beam column assembly is connected by the mortise cover plate, so that the integrity of the joint area is better, and finally the fastening between the components is completed by the high-strength bolts. The assembly type beam column joint provided by the application is connected by full bolts at a construction site, is convenient to operate, shortens the construction time, is green and environment-friendly, and has good mechanical properties; the upper and lower flange surfaces of the I-shaped steel beam are kept flat, and the subsequent floor installation is facilitated; and the joint body is in a nested structure, so that the rigidity and the strength of the joint are effectively improved.

The invention belongs to the field of electrical equipment, and relates to a control cabinet top. The cabinet top of the control cabinet comprises a top plate, a rotating structure, a spring, a rotating pipe, a cover body, a wind resistance structure, a movable scraping structure and a pull rope. An opening is formed in the top plate; the rotating structure is rotatably mounted below the opening of the top plate, the rotating structure is connected with a spring, and the upper end of the spring is connected with a rotating pipe; a cover body is fixedly mounted at the upper end of the rotating pipe; a through hole with the same inner diameter as the rotating pipe is formed in the cover body; a wind resistance structure is slidably installed on the cover body, a movable scraping structure capable of moving up and down is arranged below the wind resistance structure, and the lower surface of the movable scraping structure makes contact with the top plate. The wind resistance structure is connected with a pull rope, and the pull rope penetrates through the rotating pipe and is connected with the rotating structure. According to the control cabinet top, a top air outlet heat dissipation mode of an indoor control cabinet is reserved, heat at the top of the cabinet body can be dissipated, external rain and snow are prevented from entering the cabinet body, and heat dissipation can still be kept in rainy, snowy and windy weather.
