This invention belongs to the field of detonator wire testing technology, specifically a multi-type switching system and device for electronic detonator leads based on relay parallel connection, including a host computer; the host computer is connected to a test host device via signals; the test host device is connected to multiple sets of communication wire switching devices via signals; and the communication wire switching devices are connected to a module terminal test device via signals.

The application discloses a novel active fireproof distribution box in the technical field of distribution boxes, which comprises a box body, and circular shafts are fixedly installed at the back of both sides of the inner cavity of the box body. The high-pressure cavity, electromagnetic valve, circular air bag and first thorn needle are arranged. When a fire breaks out inside the box body, dense smoke will be continuously generated inside the box body. At this time, the two smoke sensors can sense the generation of the dense smoke and send a signal to the controller. The controller will control the electromagnetic valve to open. At this time, the high-pressure gas in the high-pressure cavity can enter the inside of the bottom cavity. Under the action of the air pressure, the moving plate can drive the first thorn needle to move downward. Finally, the bottom end of the first thorn needle can puncture the circular air bag, so that the circular air bag is burst open. At this time, the dry powder in the circular air bag can be scattered downward, so that the effect of extinguishing the fire source inside the box body can be achieved, and the active fireproof purpose is effectively achieved.

The utility model discloses a foldable electric tricycle carriage frame, including first frame board, the right -hand member welding of first frame board is connected with second frame board, the left side of second frame board is opened with first fixed hole, the upper end of first frame board is close to the front -back side fixedly connected with slide rail, the slide rail is connected with carriage side baffle through the sliding slot sliding, the carriage side baffle is swingly connected with extension baffle through the pin shaft, the carriage side baffle is swingly connected with extension baffle through the pin shaft, thereby has increased the height of original side baffle, and the convenient load thing to the goods plays the restriction, when using, will the carriage side baffle together with extension baffle through the sliding slot on the slide rail and move adjustment, will the fourth hand screw rod screw connection in second fixed hole, to the carriage side baffle of moving adjustment is positioned, folds extension baffle and carriage side baffle, and the extension baffle after folding can act as the table top use, increases the article display space when the stall.

The utility model relates to the technical field of show case, especially a folding show case and folding combination show case, including side frame, several groups of layer board, two groups of symmetric setting vertical rod, the below of layer board is provided with the latch piece, is connected through several groups of cross bar between two groups of vertical rods, side frame and vertical rod rotary assembly and can be folded to the cross bar, layer board rotary assembly is on the vertical rod, the latch piece and vertical rod sliding assembly, when the latch piece and vertical rod are connected, layer board is with the latch piece as the pivot and is folded to two groups of vertical rods between the upper turning, when the latch piece and vertical rod are separated, layer board can be disassembled from the vertical rod, through setting the latch piece, both can make layer board in 90 degree range free turnover, realize layer board flexible rotary folding, also can make layer board and vertical rod through the sliding quick disassembly and assembly of latch post, after layer board disassembly, can improve the bearing capacity of show case, satisfy the diversified use demand under different scenes.
