50results about How to "Prevent breakage etc." patented technology

The invention relates to a device with an interface protective cover, which comprises the interface protective cover, a connecting piece and a main body, wherein the connecting piece comprises a connecting part, a sliding part and a guide groove; one side wall of the main body is provided with an opening; a guide post and a limited post are arranged on the bottom, which is opposite to the opening, of the main body; the sliding part of the connecting piece passes through the opening and enables the guide post and the limited post to be positioned in the guide groove; the limited post is positioned on the extended line of the connecting line of the guide post and the opening; the top of the limited post is an inclined plane; when the interface protective cover is opened in a wrong direction, the limited post props against the guide groove to prevent the occurrence of wrong opening; and when the interface protective cover is opened correctly, the guide groove slides on the limited post along the inclined plane of the limited post until the guide post props against the limit groove, so that the interface protective cover is opened normally. In the invention, the limited post is additionally arranged in the device with the interface protective cover, thereby effectively preventing the interface protective cover from being opened in wrong direction so as to cause the breakage of theconnecting piece and the like.

The invention relates to an air exhausting and temperature measuring pipe for hyperthemal perfusion treatment of an abdominal cavity. The air exhausting and temperature measuring pipe comprises an air exhausting pipe body and a temperature detecting unit. The air exhausting pipe body comprises an inner pipe section stretching in the abdominal cavity and an outer pipe section located outside the abdominal cavity all the time. The inner pipe section is provided with an inflation air bag which surrounds the outer wall of the inner end of the inner pipe section. A side hoe is formed in the side wall of the inner end of the inner pipe section, and an inflation connector is arranged on the outer pipe section. The inflation connector is connected with the inflation air bag through an air pipeline located on the inner side of the air exhausting pipe body. The temperature detecting unit comprises a temperature sensing probe fixed to the inner end of the inner pipe section, and a temperature detecting display unit located outside the abdominal cavity, and the temperature detecting display unit and the temperature detecting probe are in signal connection. The air exhausting and temperature measuring pipe is novel in structure, low in cost, capable of monitoring the temperature of perfusate at any time, exhausting excessive air in the body cavity and observing whether the body cavity is filled of the perfusate, capable of improving the precision of treatment operation and achieving safety and repeatability, and capable of being widely used for clinical body cavity perfusion treatment.

The invention discloses a weft feeder for weft processing of an air-jet loom, which comprises a motor, a motor protection case, a yarn winding disc, a yarn storage drum and a yarn clearing device. A heat dissipation groove is arranged on the top surface of the motor protection case to dissipate heat. A filter device is arranged in the tank, and a dust-proof device is arranged above the filter device. The dust-proof device includes a mounting plate and a dust-proof cover. The components include heat-absorbing pipes and heat-dissipating pipes. The invention has simple structure and strong practicability. By changing the heat dissipation mode of the original heat sink type, the heat dissipation effect of the weft feeder is improved, and the service life of the weft feeder is prolonged. At the same time, the design of the yarn clearing device , through the dual combination of the brush and the yarn scraping plate, the cleaning of the yarn storage drum is more convenient, effectively preventing the weft yarn from breaking due to excessive friction during use, and improving the comprehensive utilization efficiency.

The invention discloses a dry-process sound-absorbing ceiling for automobiles, which is formed by post-processing the ceiling slabs. The ceiling slabs are composed of 5-layer board structures, wherein the first layer board is made of weight ratio Made of 2-2.5:1 glass fiber and polyethylene rubber powder; the second layer is made of modified expanded polystyrene; the third layer is made of glass fiber modified polyethylene rubber powder : the fourth layer is made of modified expanded polystyrene; the fifth layer is made of glass fiber and polyethylene rubber powder with a weight ratio of 2-2.5:1, and the present invention is used to reduce the dry ceiling The weight of the product can be reduced, and the NVH sound absorption performance of the ceiling itself can be improved.

The present application relates to an assembly device, which is used for assembling a battery module, and the battery module includes at least two sub-modules. The assembly device includes: a working platform and a supporting mechanism. The supporting mechanism is installed on the working platform, and the supporting mechanism includes a first base, at least two first supporting components and a first driving component. Wherein the first base is set on the working platform. At least two first supporting components are arranged on the first base at intervals along the first horizontal direction, and are used to support the sub-module. The first drive assembly is connected with the first support assembly and used to drive the first support assembly to move along the first horizontal direction. The assembly device provided by this application can avoid the relative friction between the sub-module and the first support assembly, and prevent the external insulation film of the sub-module from being damaged due to friction; and the assembly device provided by this application can realize fully automated production , without manual operation, can greatly improve assembly efficiency.
