This utility model relates to the field of hydraulic control valve technology and discloses a hydraulic control valve for forklifts, including a directional valve, which is a three-position four-way electro-electromagnetic directional valve used to control the flow direction of hydraulic oil; a filter, which is installed inside the oil inlet of the directional valve and has a filter screen inside to filter impurities; and an inching valve, which is installed inside the oil outlet branch of the directional valve. One end of the inching valve is fixedly connected to a control rod, and the other end of the inching valve is equipped with a spring to control the hydraulic oil pressure. In this utility model, the directional valve controls the flow direction of hydraulic oil to achieve forklift forward and reverse switching. The inching valve adjusts the valve core position under the action of the control rod and the spring. The energy storage valve uses a spring to store and release energy when the pressure is high or low. The relief valve adjusts the size of the oil outlet through a linkage structure of small valve core compression or return spring three, achieving the effect of smooth pressure change and reduced shock in the hydraulic system.

This utility model relates to the field of gear output seat technology, specifically a sealed and dustproof gear output seat, including an output base. A dustproof component is installed on the outer wall of the output base, and a detection component is installed on the inner wall of the output base. A fixing sleeve is installed on the outer wall of the output base, and an input shaft is rotatably connected to the inner wall of the fixing sleeve. This utility model controls the operation of a lubricating oil pump through a controller, so that the lubricating oil pump draws out the lubricating oil from the inner cavity of the output base, and then discharges the lubricating oil into the inner cavity of the dustproof housing. Since the lubricating oil is discharged into the inner cavity of the dustproof housing, when the lubricating oil passes through the magnetic adsorption column, the metal debris in the lubricating oil is magnetically adsorbed by the magnetic adsorption column. Subsequently, the filter plate adsorbs the impurities and dust in the lubricating oil, and then the lubricating oil is discharged into the inner cavity of the output base through the drain pipe, thus filtering the lubricating oil in the inner cavity of the output base, so as to achieve good sealing and dustproof effect of the device.

This utility model provides a quick-release heat dissipation structure for a dynamic face recognition module of an attendance gate, comprising: an attendance machine body, wherein a heat dissipation component for heat dissipation of the face recognition module body is installed inside the attendance machine body, a module frame for mounting the face recognition module body is provided inside the right side of the attendance machine body, and the face recognition module body is mounted on the upper side of the module frame, and the heat dissipation component includes a mounting frame, wherein multiple elastic elements are equally spaced at the upper end of the mounting frame. Compared with the prior art, this utility model has the following beneficial effects: the setting of the heat dissipation component can achieve the purpose of quick disassembly of the heat dissipation component. It does not use traditional bolts or screws for fixing, but can be quickly disassembled by simply rotating, which helps to reduce the difficulty of disassembling the heat dissipation component and solves the problem of disassembly difficulty caused by bolt fixing.
