The invention discloses a brake type gradually-changed section drilling device and a using method thereof, and belongs to the technical field of underground coal mine construction. Comprising a combined rod body, the tail of the combined rod body is connected with a main control system, the combined rod body comprises a driving rod body of a hollow rod body structure, a brake rod body is arranged in the driving rod body in a sleeved mode, and the end of the driving rod body is connected with a rock-soil breaking tool bit which is of a special-shaped structure and can be opened and closed. A spiral adjusting disc capable of controlling opening and closing of the rock-soil breaking tool bit through rotation is movably arranged on the inner side of the end of the driving rod body and connected with the end of the brake rod body. A motor and a brake are arranged in the main control system, the motor drives the driving wheel to drive the driving rod body to rotate for drilling, the brake limits rotation of the brake rod body to achieve position change of the rock-soil breaking tool bit on the section sliding groove, and therefore the preset drilling hole diameter is controlled and mastered in the drilling process. The device has the advantages of reasonable structure, stable function, economy, high efficiency and the like.

The utility model belongs to the technical field of rubber rings, and particularly relates to a code spraying mechanism of rubber ring code spraying and cutting equipment, which comprises a bottom plate. A fixing support is fixedly installed on one side of the top of the bottom plate, a driving mechanism is arranged on one side of the fixing support, and a jacking mechanism is arranged on the side, away from the driving mechanism, of the fixing support. An adjusting mechanism is arranged on the side, away from the fixing support, of the rotating disc, and a moving mechanism is arranged on the top of the bottom plate. A drying mechanism is arranged at the top of the bottom plate, and a code spraying mechanism is arranged at the top of the bottom plate; through the arrangement of a first servo motor, a driving shaft and a one-way rotating structure, the first servo motor and the driving shaft are matched for use, so that the one-way rotating structure can drive a transmission shaft to rotate through forward rotation, and thus an arc-shaped frame can rotate to open a small fixing rod; when the first servo motor turns over, the one-way rotating structure can drive the transmission shaft and the connecting ring to rotate synchronously.

The present invention discloses a washing machine, comprising a housing, a washing tub rotatably arranged in the housing, a water receiving device arranged in the housing for collecting water discharged from the washing tub, and a drainage channel. A first drainage port is arranged at the lower position of the peripheral wall of the washing tub. The drainage channel is arranged on the peripheral wall of the washing tub and communicates with the first drainage port to guide the water discharged from the washing tub to the bottom of the washing tub. A water inlet is arranged at the upper part of the drainage channel, and a water outlet is arranged at the lower part. The drainage channel is sealed on the first drainage port of the peripheral wall of the washing tub, and the water inlet is communicated with the first drainage port. The water receiving device comprises a water collecting chamber and at least one second drainage port, and the water outlet of the drainage channel for downward drainage is located in the water collecting chamber. The present invention installs a drainage channel at the lower part of the peripheral wall of the washing tub to guide the water discharged from the first drainage port downward, which can not only prevent the water receiving device from extending upward to achieve the expansion effect, but also guide the drainage to the water collecting chamber of the water receiving device, improve the drainage speed, and have the effect of preventing splashing water.

The present invention provides a washing machine, comprising: an inner barrel for independently holding washing water when washing clothes; and a lint filter device, which is arranged on the barrel wall of the inner barrel and is used to filter lint in dehydration drainage. The washing machine of the present invention realizes "no outer barrel" and at the same time, a lint filter device for filtering lint in dehydration drainage is arranged on the inner barrel, thereby filtering lint in the dehydration drainage process, preventing the lint in the dehydration drainage from blocking the dehydration drainage channel, and ensuring the dehydration effect.

The present disclosure describes a rotary lifting dilator, comprising an upper leaf assembly and a lower leaf assembly, the upper leaf assembly comprising a pressing part, an upper leaf, and a first connecting part, the lower leaf assembly comprising a holding part, a lower leaf, and a second connecting part; the first connecting part comprising a guide groove and a first rotating shaft, the guide groove comprising a first protrusion extending towards the lower leaf; the second connecting part comprising a groove and a waist-shaped hole, an end of the groove extending towards the upper leaf forming a second protrusion protruding from the lower leaf; the first protrusion movably placed in the groove, the second protrusion placed in the guide groove and slidable along the length direction of the guide groove, the first rotating shaft slidably arranged in the waist-shaped hole; pressing the pressing part, the second protrusion sliding in the guide groove to make the first protrusion move in the groove relative to the second protrusion and make the first rotating shaft slide in the waist-shaped hole. Thus, a dilator capable of realizing rotating shaft dilatation and push-pull dilatation at the same time and convenient to use can be provided.

This utility model belongs to the field of cultivation support technology, and in particular to a cultivation support for vegetable and fruit cultivation. A support frame is fixedly connected to the top of the base, and a connecting seat is fixedly connected inside the support frame. A flipping component is fixedly connected to one side of the connecting seat, and an extension component is fixedly connected to one end of the connecting seat. The flipping component includes a connecting plate, and the extension component includes a second motor. This utility model uses a first motor to drive a drive gear to rotate, which in turn drives a first connecting ring and the cultivation seat to rotate, achieving a flipping adjustment of the cultivation seat's height. Then, the second motor drives a threaded rod to rotate, which causes the fixed seat and connecting frame to move along the position of the directional wheel. The movement of the connecting frame causes the extension seat to slide along the surface of the cultivation seat, thus expanding the cultivation space.

The utility model discloses a capacity expansion power distribution cabinet belongs to power distribution cabinet technical field, including the casing and install power distribution subassembly in the casing, the both sides of casing are established with first input and second input respectively, and power distribution subassembly is connected with module cabinet through first input or second input. The utility model discloses the both sides of capacity expansion power distribution cabinet are established with input, and can set up two sets of input, output power distribution subassembly in the inside of power distribution cabinet, when the capacity expansion power distribution cabinet is applied to double machine cabinet, can according to actual scene arbitrarily select the input of one side, and with the inside any one set of power distribution subassembly connects to adapt to the requirement of different sites. In high power demand scene, the capacity expansion power distribution cabinet can be expanded to three machine cabinets, and both sides are input and the two sets of power distribution subassembly in the inside are all connected with module cabinet, realize the effect of expansion, and do not need to change the overall structure of capacity expansion power distribution cabinet, and the simple structure is convenient and easy to handle.
