7results about How to "Prevent mutual separation" patented technology

This application discloses an electronic device fixing device, an electronic device assembly, and a vehicle, belonging to the technical field of vehicle accessories. The disclosed vehicle includes an electronic device assembly, which in turn includes an electronic device fixing device. The electronic device fixing device includes a main body with a plug-in portion and a locking portion. The plug-in portion is used for plugging into and engaging with an electronic device. At least a portion of the locking portion is retractable relative to the plug-in portion and can automatically reset, thereby avoiding a limiting portion on the electronic device during the plug-in engagement process and limiting the engagement with the limiting portion when the plug-in portion is engaged with the electronic device. The connection between the electronic device fixing device and the electronic device disclosed in this application is relatively reliable, with a low probability of separation.

This application relates to the field of electric toothbrush technology, and more particularly to a vibrating electric toothbrush. During operation, an adapter connects the vibrating toothbrush head to the handle, preventing direct connection between the drive unit and the toothbrush head. This creates a buffer between the adapter and the handle, reducing the impact of vibration on the connection and ensuring its reliability. This also reduces the risk of loosening or jamming during use. During the engagement of the toothbrush head and handle, one end of the drive shaft of the drive unit, installed inside the handle, is inserted into a slot in the adapter, and the locking part engages within the slot. The inner wall of the slot limits the engagement, preventing the toothbrush head from detaching and improving the reliability of the connection.

This utility model relates to the field of limiters, specifically a door limiter applied to energy storage cabinets or liquid-cooled cabinets. It includes a positioning bracket for connecting to the cabinet body, a door limiting tube for connecting to the cabinet door, and a connecting rod. The door limiting tube has a guide groove penetrating its inner and outer surfaces, a mounting hole, a first limiting hole, and a second limiting hole. When the door limiting tube is connected to the cabinet door and the positioning bracket is connected to the cabinet body, the movement path of the second pin is restricted within the contour formed by the guide groove, the first limiting hole, and the second limiting hole. The distance between the mounting hole and the positioning bracket is greater than the distance between the first limiting hole and the positioning bracket, and also greater than the distance between the second limiting hole and the positioning bracket. During the opening of the cabinet door relative to the cabinet body, as the angle between the cabinet door and the cabinet body gradually increases, the distance between the second pin and the mounting hole gradually increases until the second pin slides into the second limiting position and terminates its movement, thereby preventing the second pin on the connecting rod from dislodging from the mounting hole.

This application relates to the field of electric toothbrush technology, and more particularly to a compatible electric toothbrush. When the toothbrush handle is fitted with a first toothbrush head, after the drive shaft is inserted into the slot, the locking part engages into the slot to prevent the first toothbrush head from detaching from the toothbrush handle. After the drive shaft is inserted into the insertion slot, the locking protrusion engages into the slot to prevent the second toothbrush head from detaching from the toothbrush handle. The first and second toothbrush heads are adapted to different operating modes. This allows the electric toothbrush to be compatible with different toothbrush heads. When users need to use different cleaning modes, they can simply replace the corresponding toothbrush head to meet their cleaning needs, reducing living costs and improving the user experience.

The present application relates to the technical field of underground engineering seepage inversion, in order to improve the accuracy of the generation of the permeation tensor field, a three-dimensional seepage field inversion analysis method suitable for anisotropic rock mass is provided, the drilling lithology, the occurrence of structural plane, the segmented water pressure, the water level monitoring, the excavation surface groundwater inflow, the recharge boundary and the excavation surface data are mapped to the three-dimensional unit to form the permeation tensor generation condition; the reserved parameters and the parameters to be updated are divided in the condition normalization flow affine coupling layer, the conduction relationship graph is constructed based on the reserved parameters, the random walk absorption probability and the direction change amount are calculated, and the scale parameter and the translation parameter generation link are embedded to update the tensor parameters; the three-dimensional anisotropic permeation tensor field and the directed connected state are output by matching the water level and the inflow response, and the accuracy of the generation of the permeation tensor field is improved.

This utility model belongs to the field of printer technology and discloses a printer mounting structure and printer components. The printer mounting structure includes a printer housing for mounting the printer body and a printer bracket for fixing it to a column. The printer housing and the printer bracket are firstly provided with a sliding groove, and secondly provided with a slide rail. The sliding groove and the slide rail are mutually engaged through the insertion of a first insert and a second slot, and the insertion of a second insert and a first slot, to prevent them from separating. This allows for a stable connection between the printer housing and the printer bracket, and consequently, a stable connection between the printer body and the column. In addition, this printer mounting structure is connected to the slide rail through a sliding engagement. The position of the slide rail can be switched by sliding the slide rail. When the slide rail is in the mounting position, the printer body and the column are stably connected. When the slide rail is in the disassembly position, it facilitates the assembly and disassembly of the two components.

The application belongs to the technical field of power transmission line operation and maintenance, and discloses a linkage method and system combining edge intelligent decision and live-line defect elimination tools. The application can realize on-site identification and edge side analysis of the fastener of the power transmission tower by collecting image data, vibration data and bolt models of the fastener of the power transmission tower, inputting the standardized preprocessed data into the bolt defect fine-grained identification network deployed on the edge side, distinguishing different defect types such as bolt loosening, thread corrosion and missing lock washer, and obtaining defect grades, attitude parameters and confidence information. The application can improve the fine degree of fastener defect identification and reduce manual secondary verification.
