The utility model discloses an anti-loosening and anti-falling plugboard, which is characterized in that a plugboard cavity is formed by a main shell and a face shell, the face shell is provided with an adaptive groove, a jack and a tongue hole, and the plugboard cavity is provided with a clamping tongue linked with a power supply push switch. When the button of the power supply push switch is pressed down, the conductive chuck is powered on and the clamping tongue extends out to lock the plug, and when the button rebounds, power is cut off and the clamping tongue retracts. According to the utility model, anti-drop locking and power supply control are integrated into single button operation, so that the design is simplified, and misoperation can be effectively avoided; and low plugging force and high connection reliability are both considered, the problems that a traditional structure is complex in operation and easy to loosen are effectively solved, and the connector is suitable for high-vibration scenes such as electric automobiles.

This utility model discloses a screening device for rubber compound production, relating to the field of raw material screening technology. It includes a base and a screening box. A screen plate is installed inside the screening box, and a vibrating motor is fixedly installed on the lower surface of the screening box. Four vibration damping springs arranged in a circular array are provided between the screening box and the base. A transfer mechanism is provided on the lower surface of the base, and a top cover is threadedly connected to the upper surface of the screening box. During use, the vibrating motor drives the screening box to vibrate, thoroughly screening the granular raw materials through the screen plate. Finer particles fall through the screen plate into the screening box and flow out through the fine material outlet, while larger particles flow out through the coarse material outlet. The device features a simple structure and good screening effect. During this process, the operation of the vacuum pump draws the dust generated during the screening of the granular raw materials into the dust filter box through the dust suction hole, annular cavity, and vacuum pipe, achieving a dust collection effect and preventing dust from being emitted.

The utility model belongs to graphite gasket production technical field discloses a graphite plate cutting equipment for graphite gasket production, including pedestal, the central position of pedestal upper surface is equipped with working cavity, the left and right sides of pedestal upper surface front end are fixedly connected with the limiting rod, the outside of two limiting rods is connected with the lifting platform of sliding, the utility model discloses the cutting knife on the lifting platform bottom end connecting seat can carry out the cutting work of graphite plate through the lifting mechanism drive lifting platform downward movement, when the lifting platform lower surface and the pedestal upper surface contact, the first magnetic block on the lifting platform can be quickly adsorbed with the second magnetic block, after cutting, lifting is carried out through the lifting platform, lifting platform can drive the clamping seat to cancel the spacing of graphite plate through the pull rope, and simultaneously the first magnetic block of lifting platform bottom end can drive the bracket to be lifted through the second magnetic block, and make the bracket cut after graphite plate fast lift and discharge.

The utility model relates to the technical field of dehumidifiers, in particular to a dehumidifier with a humidity adjusting function, which comprises a dehumidifier body, a mesh enclosure is rotatably mounted at an air inlet of the dehumidifier body, an air outlet is formed in the lower side of one side wall of the dehumidifier body, and a dustproof mesh plate is fixed in the air outlet; a negative pressure suction nozzle is arranged on the lower side of the outer wall of the net cover and fixedly connected with the outer wall of the dehumidifier body, a filter box is fixed to the lower side of the outer wall of the dehumidifier body, a filter screen plate is fixedly installed in an inner cavity of the filter box, the bottom of the filter box fixedly communicates with a negative pressure fan, and the top of the filter box fixedly communicates with the negative pressure suction nozzle through a fixing pipe. The negative pressure fan works to enable the filter box to form negative pressure, so that the negative pressure suction nozzle can suck and remove dust and impurities on the surface of the mesh enclosure, cleaning is achieved, original manual operation is replaced, convenience of cleaning operation is improved, and meanwhile negative pressure dust removal is achieved, and dust raising is avoided.
