The present invention provides a device for mouth opening exercise for patients after radiotherapy, including two upper and lower tooth pads and a bracket for fixing the tooth pads, the tooth pads including an upper tooth pad and a lower tooth pad, the bracket being a telescopic structure, and a height measuring device being fixed on the bracket. The bracket is a rhombus-shaped movable frame, and a chin fixing plate is also provided below the rhombus-shaped movable frame. The present invention uses upper and lower tooth pads, which are easy to clean, have very little residual bacteria, and are more hygienic than the corks currently used in clinical practice; the height between the upper tooth pad and the lower tooth pad can be adjusted arbitrarily, and the user can adjust to his or her own mouth opening limit according to his or her personal situation; a height measuring device is provided, and the user of the height measuring device, medical staff, and accompanying personnel can intuitively see the mouth opening height and standardize the mouth opening exercise; the scale of the height measuring device can measure the height between the upper teeth and the lower teeth of the user to determine the mouth opening height.

The utility model discloses a storage device for rape seed breeding, and relates to the technical field of rape seed storage devices.The storage device comprises a base, two supporting seats are symmetrically installed on the top face of the base, the two supporting seats are jointly and rotationally connected with a storage barrel, a rotating mechanism is arranged on the top face of the base, and the rotating mechanism drives the storage barrel to rotate; when the seed stirring device is used, the driving mechanism drives the material stirring shaft to rotate, then seeds are stirred through the material guide plate, static accumulation of the seeds is avoided, the porosity among the seeds can be increased, cold air is discharged through micropores of the material guide plate in cooperation with the cold air conveying mechanism, and therefore the seed stirring device is used for stirring the seeds. And cold air can quickly take away heat emitted by the seeds, so that mildew caused by accumulation is avoided.

This invention relates to the field of N-(2,4-dinitrophenyl)-4-nitrobenzamide preparation technology, specifically to a green method for preparing nitramide compounds. The method involves adding a catalyst and dispersant to a reactor and mixing them uniformly. Then, a first and a second stream of materials are simultaneously added dropwise to the reactor for reaction. The temperature within the system is controlled during the dropwise addition. After the dropwise addition is complete, the temperature is increased to continue the reaction. After the reaction is completed, N-(2,4-dinitrophenyl)-4-nitrobenzamide is obtained through post-treatment. The first stream is a dispersion containing 4-nitro-N-phenylbenzamide, and the second stream is a nitrating agent consisting of a uniform mixture of N₂O₅ and nitric acid. This preparation method features high product conversion rate, a mild reaction process, safe and controllable production process, effectively reduces the amount of residual intermediates, and minimizes pollution.

This utility model relates to the field of rubber extruder technology, specifically a funnel-shaped rubber extrusion device. The device includes a barrel for connecting to the rubber extruder hopper, a discharge head detachably connected to the end of the barrel, and a plunger head slidably connected inside the barrel. A mandrel is disposed inside the discharge head, and a funnel-shaped extrusion orifice is formed at the rear end of the mandrel. A conical head that mates with the inclined surface of the extrusion orifice is fixedly connected to the front end of the plunger head. The funnel-shaped mandrel design of this device improves the utilization rate of rubber in a single extrusion, reduces the amount of rubber remaining in the die head, and minimizes material loss and energy consumption caused by secondary extrusion. The device also features a high sealing strength between the discharge head and the barrel, preventing rubber residue from remaining in the gap between them. Furthermore, the device allows for the replacement of the central mandrel, enabling the processing of rubber of corresponding sizes according to different product dimensions.

The invention relates to a passive structure for reducing corrosion in a connector. A connector structure that can help reduce contact corrosion in a connector receptacle and can reduce liquid entering an electronic device that houses the connector receptacle. One example may increase the effective width between adjacent contacts. The example and other examples may force dendritic growth to occur in a location where the dendritic growth may be at least partially cleared by inserting a corresponding connector into the connector receptacle.
