This utility model belongs to the field of hydraulic support technology, and in particular to a limiting device for a hydraulic support in mining equipment. It includes a control console and a limiting box plate. An arc-shaped groove is formed on the periphery of the limiting box plate. A U-shaped block is fixedly installed on the inner bottom wall of the control console. A control rod is rotatably connected to the U-shaped block via a rotating shaft. A rectangular groove is formed at the upper end of the control rod, and a connecting rod is inserted into the inner wall of the rectangular groove. A second control rod is fixedly welded to the upper end of the connecting rod. An elastic component connects the rectangular groove and the connecting rod. This utility model changes the original matching locking box design by dividing a control rod into two parts, with the addition of an elastic component and a limiting component. This allows the entire unit to directly apply force to the second control rod to complete the rotation of the control rod, eliminating the cumbersome operation of two parts and improving overall practicality.

The utility model provides a portable numerical control machine tool simulation training machine, which comprises a device main body, an operation panel, a display, a machine tool hand wheel, an electric control module, a computer host, a control switch and a power supply, the device body is in a horizontal box shape and comprises a top plate, a bottom plate and a circumferential side plate, the operation panel is installed on the top plate, the electric control module, the computer host and the power source are installed in a box inner space of the device body, and the control switch is installed on the top plate or the bottom plate or the circumferential side plate. The displayer and the machine tool hand wheel are arranged outside the device body. According to the portable numerical control machine tool simulation training machine, the device body is in the shape of the horizontal box body, the operation panel, the electric control module, the computer host, the power source and the control switch are integrated on the device body, the structure is compact, the occupied space is small, the space utilization rate of the device body is high, and the production cost can be reduced; meanwhile, the device is convenient to carry and can be suitable for various training and teaching occasions.

The utility model belongs to the technical field of shower head products, and particularly discloses an anti-loosening easy-to-overhaul shower head water inlet structure which comprises a cover plate and a water inlet connecting kit, a mounting hole is formed in the center of the cover plate, and the water inlet connecting kit is arranged in the mounting hole; the water inlet connecting external member comprises an external member main body and an external member lower body, the external member main body is arranged at the upper part of the mounting hole, the external member lower body is arranged at the lower part of the mounting hole, and the external member lower body penetrates through the mounting hole and is connected with the external member main body. The water inlet connecting external member and the cover plate can be quickly assembled by enabling the external member lower body to penetrate through the mounting hole to be connected with the interior of the external member main body subsequently, and when subsequent maintenance operation is needed, the water inlet connecting external member can be quickly detached from the cover plate only by detaching the external member lower body, so that the maintenance operation of the water inlet connecting external member or the shower head can be quickly and conveniently carried out.

This utility model relates to an electrolyzer device and hydrogen production equipment, which includes a support assembly, an electrolyzer assembly, and a hydraulic assembly. The electrolyzer assembly includes multiple electrolysis chambers arranged sequentially along a first direction, and each electrolysis chamber is slidably connected to the support assembly; the power output end of the hydraulic assembly is fixedly connected to one end of the electrolyzer assembly; and the hydraulic assembly can drive the electrolysis chambers to move along the first direction. In the above-mentioned electrolyzer device and hydrogen production equipment, since the power output end of the hydraulic assembly is fixedly connected to one end of the electrolyzer assembly, the movement of the electrolysis chambers along the first direction can be achieved by driving the hydraulic assembly, thereby changing the distance between the multiple electrolysis chambers, thus realizing the rapid sealing or disassembly of the electrolyzers, making the disassembly and assembly efficiency of the entire electrolyzer high, thereby improving the development progress of the electrolyzer and meeting the needs for rapid testing, rapid iteration, rapid development and market launch of new materials and new products.

The utility model discloses a coal mine geological drilling sampling device, which belongs to the technical field of drilling sampling and comprises a main machine table. An ejector rod capable of moving up and down is vertically installed on the main machine table, a rod body of the ejector rod is sleeved with a reset spring for pushing the ejector rod to move upwards, a vertically-arranged sampling core is detachably installed at the bottom of the ejector rod, and a hollow cavity is formed in the sampling core; a groove with the same length as the sampling core is formed in the side wall of the sampling core in the axial direction; a labor-saving lever capable of pressing the ejector rod downwards and driving the sampling core to drill downwards is rotationally mounted at the top of the main machine table. According to the coal mine geological drilling sampling device, the groove is formed in the side wall of the sampling core, so that a sample in the hollow cavity of the sampling core is easily separated from the cavity; and secondly, the ejector rod is frequently knocked by the labor-saving lever, and the vibration sense can be transmitted into the sampling core along the ejector rod, so that the sample in the hollow cavity of the sampling core is quickly separated from the cavity.
