3results about How to "Simplify complex operations" patented technology

The application provides a switch body and a rotary disconnecting switch, relates to the technical field of low-voltage electrical apparatuses, and comprises a switch module, a contact assembly arranged on the switch module, and a wiring pipe body connected with the contact assembly. The contact assembly can be driven to close or open. The switch module is used for plugging and unplugging the wire through the wiring pipe body. Therefore, the wiring of the switch body can be completed in the form that the end of the wire is directly plugged into or unplugged from the wiring pipe body by using the structure of the wiring pipe body, so that the complicated operation during wiring of the switch body is simplified, and the wiring pipe body can also coat the outer peripheral wall of the wire, so that a reliable electrical connection relationship is formed. In addition, the wire is directly plugged and unplugged by the wiring pipe body, so that the wiring pipe body occupies a smaller space, the layout difficulty of the components in the switch body is reduced, and the miniaturization of the switch body is facilitated.

The invention relates to a multifunctional heat preservation box for simulating a soft rock shear rheological experiment shear box based on five-field coupling. The invention relates to the technical field of rock mechanics tests, in particular to a multifunctional heat preservation box applied to a THMC-B multi-field coupling shear rheological experimental instrument, which comprises a heat preservation box front part, and an internal electronic temperature display meter and heat preservation glass are mounted on the heat preservation box front part; the thermal insulation box rear part is fixed on the experimental instrument through a vertical steel column and a lateral steel column, a seepage field / chemical field water inlet and a seepage field / chemical field water outlet are formed in the rear part of the thermal insulation box rear part, holes for a horizontal static load electric cylinder, a horizontal dynamic load electric cylinder and a normal dynamic load electric cylinder are reserved in the whole thermal insulation box, and thermal insulation felt cloth is mounted at the openings. The device has the advantages that the device is easy to install and convenient to use, the heat preservation efficiency needed in a temperature field experiment is effectively improved, meanwhile, the temperature of the internal shear box can be detected in real time, and temperature measurement in the experiment is facilitated. Besides, compared with a traditional heat preservation box, the heat preservation box is designed through a novel composite multi-layer material, temperature dissipation and heat exchange of the heat preservation box are greatly reduced, and the heat preservation box has the advantage of being beneficial to popularization and test.

The utility model relates to the technical field of window locks, and discloses an automatic locking window lock which comprises a panel, a moving groove is formed in the upper end of the panel, a plurality of first rectangular sliding grooves are formed in the bottom end of the moving groove, the upper left end of the moving groove is fixedly connected with a limiting plate, a lock catch box is arranged at the horizontally corresponding end of the panel, and a lock catch is arranged in the lock catch box. By arranging the handle, the first limiting rod, the elastic shifting piece and the clamping block, the handle is pushed to move leftwards, the clamping block at the lower end of the spring bolt is moved to the left end of the elastic shifting piece, the elastic shifting piece is clamped with the clamping block, the spring bolt can be conveniently fixed, the first limiting rod can be linked to drive the spring bolt to reset, a window can be rapidly unlocked, and complex operation steps of a traditional window lock are simplified; and by arranging a first reset spring, a spring bolt, a clamping block and a limiting base plate, the spring bolt automatically moves rightwards through the elastic force of the first reset spring, the clamping block and the limiting base plate are matched for clamping, and self-locking is completed at the moment when the window is closed.
