This utility model provides a cooking utensil, comprising: a pot body with a plurality of pot teeth spaced apart, one of which is a limiting tooth, the outer surface of which includes a protruding limiting surface; and a lid, which is closable and can be locked onto the pot body, engaging with the limiting tooth. The lid has a stop-opening element; when the lid is locked with the limiting tooth and the cooking utensil is under pressure, the stop-opening element interferes with the protruding limiting surface to lock the lid onto the pot body. The design of this application effectively solves the problem in related technologies where the inclusion of limiting holes and limiting protrusions increases processing steps and leads to higher processing costs.

The adjusting mechanism comprises a supporting plate, an adjusting assembly is arranged on the supporting plate, the adjusting assembly comprises adjusting frames, adjusting rods, adjusting holes and inserting bolts, the adjusting frames are fixed to the two sides of the supporting plate, the adjusting rods slide in the multiple adjusting frames, the adjusting holes are distributed in the outer walls of the adjusting rods, and the inserting bolts are inserted into the adjusting holes. The outer side of the adjusting frame is provided with a fixing assembly, the fixing assembly comprises a fixing sleeve, a clamping rod, a movable groove, a clamping block, a push spring and a clamping ring, the fixing assembly adopts a combined structure of the fixing sleeve and the clamping rod, and through a self-locking mechanism of the clamping block and the push spring in the movable groove, the rapid locking function can be achieved without tools; the inclined plane design of the inner side of the clamping ring and the top end of the clamping block enables the locking process to be smoother, the pushing block and the clamping block which are subjected to round corner processing reduce operation resistance, and the ingenious matching of the sliding groove, the sliding sleeve and the threaded sleeve provides a convenient unlocking mode.

The utility model is suitable for high -voltage switch cabinet technical field provides a kind of high-voltage switch cabinet grounding switch operating mechanism, including cabinet and the grounding switch working part in the cabinet of cabinet, the outside of cabinet is provided with sector recess, first limit rod, second limit rod are fixed in sector recess, the utility model adopts the gear rack structure of straight-toothed wheel and straight-toothed surface engagement, converts rotation movement into linear motion, then through first, second limit rod is positioned with auxiliary, while maintaining transmission efficiency, maintain force balance, avoid the local stress concentration problem of gear, and horizontal shift rod is slidably connected with the inner wall of cabinet by slide, provides stable guiding support, reduces the deviation or jam in transmission process, improves reliability, through the cooperation dispersion operating torque of gear rack and elastic component, reduce handle operating resistance, prolong component life, ensure that automatic locking after opening and closing brake is in place, avoid misoperation or loosening, improve operating safety.

The invention relates to the technical field of police security and protection equipment, and particularly discloses a police on-site blocking and isolating device. The top cap is arranged at the top of the column; the base is arranged at the bottom of the upright; the inserting grooves are formed in the side walls of the stand columns. The trigger swing block is arranged in an inner cavity of the stand column on the inner side of the inserting groove; the transmission push rod is arranged in an inner cavity of the stand column in a penetrating mode and can vertically slide and displace. Two ends of the transmission connecting rod are rotatably connected to the lower end of the trigger swing block and the upper end of the transmission push rod; the lifting bottom plate is fixedly arranged at the bottom end of the transmission push rod and located in an inner cavity of the base. The multiple vacuum suction cups are arranged on the bottom face of the lifting bottom plate. The reset spring seat is arranged between the inner bottom surface of the base and the lifting bottom plate; the pneumatic auxiliary pressure relief mechanism is arranged in the transmission push rod and extends out of the stand column. On-site rapid isolation, anti-toppling powerful anchoring and vacuum breaking withdrawing are achieved, and linkage triggering of the bottom powerful adsorption action is achieved along with the natural insertion state of the plug.

The present application relates to the field of multi-link support mechanism, and discloses a sliding groove multi-link support mechanism, which comprises a mounting seat connected to a first mounting base and provided with a guide sliding groove, a hinge assembly comprising a first link, a second link and a third link, first and second ends of the first link are respectively slidably hingedly connected to the guide sliding groove and hingedly connected to a second mounting base to form a first hinge point, the second link is crossly arranged with the first link and is hingedly connected at the cross position to form a second hinge point, first and second ends of the second link are respectively hingedly connected to the mounting seat and a first end of the third link to form a third hinge point, a second end of the third link is hingedly connected to the second mounting base to form a fourth hinge point, and a line connecting the first, second, third and fourth hinge points forms a quadrilateral, a transmission assembly is arranged on the mounting seat and is used for transmission cooperation with the first mounting base, and an elastic assembly is arranged on the mounting seat, and the elastic assembly exerts elastic force on the transmission assembly to enable the second mounting base to maintain its opening and closing state.

The application discloses an endoscope catheter and an endoscope, and belongs to the technical field of medical devices. A first joint surface and a second joint surface are arranged at the distal end of a catheter body, and a first counter surface and a second counter surface are arranged at the proximal end of a catheter tip, so that a double cooperation connection structure in the radial direction and the axial direction can be formed, and the path of lubricating medium of a lubricating layer penetrating into the inside of the endoscope catheter is significantly prolonged. Meanwhile, the lubricating layer ends at the transition area of the outer surface of the catheter body, the transition area is located between the lubricating layer and the catheter tip, an isolation belt without coating is formed, and the medium of the lubricating layer has a certain spacing with the connection interface of the catheter body and the catheter tip. Therefore, the risk of the lubricating medium penetrating into the inside through the connection interface is blocked in the structure, the operation resistance of medical staff is reduced, and the treatment risk caused by the pollution of the instrument is avoided.
