6results about How to "Solve sagging" patented technology

The application provides a side-opening back door assembly and a vehicle, and belongs to the technical field of vehicle back doors. A force transmission cavity arranged on a first side of a window frame close to a door body and a hinge mounting surface correspond to each other in the up-down direction, forming a through hinge force transmission channel. The load borne by the hinge assembly can be more smoothly dispersed to the entire window frame and the door body frame through the hinge force transmission channel. The force distribution of the hinge assembly is optimized, the risk of local overload is reduced, the overall stiffness of the door body is improved, the sagging problem of the existing side-opening back door caused by force transmission defects is solved, and the reliability, durability and vehicle driving quality of the door body are significantly improved. By offsetting the spare tire to one side of the hinge assembly, the force arm of the spare tire gravity relative to the hinge assembly can be shortened, the torque borne by the hinge assembly is also reduced, the risk of deformation of the hinge assembly under long-term alternating load is reduced, and the sagging of the door body is effectively avoided.

The utility model discloses a pull type plane lock which comprises a lock body, an inner panel and an outer panel. The lock body comprises a lock shell and a spring bolt, the rear end of the spring bolt is connected with an unlocking matching piece, and the unlocking matching piece is provided with a matching through hole. An inner pulling plate and an outer pulling plate are rotationally arranged on the inner panel and the outer panel respectively, the lower end face of the inner pulling plate is connected with an inner push rod, and the lower end face of the outer pulling plate is connected with an outer push rod; the lower end of the inner push rod and the lower end of the outer push rod penetrate into the matched through holes from the corresponding sides of the lock shell respectively. Unlocking is achieved by pulling the inner pulling plate or the outer pulling plate; the door lock is used for replacing the unlocking mode that a traditional door lock is unlocked by rotating a door handle, and the problem that after an existing door lock is used for a period of time, the door handle shakes up and down and droops due to spring fatigue is effectively solved. Meanwhile, the unlocking operation of the door lock is realized by pulling the inner pulling plate or the outer pulling plate, so that the unlocking operation of the door lock is simpler and more convenient; the door lock is simple in structure, and the manufacturing cost is reduced.

This invention relates to a folding canopy-type inner protective device and a passageway containing it, belonging to the technical field of rail vehicle passageways. The folding canopy-type inner protective device includes an inner folding canopy, side beams, and a vertical support assembly. The inner folding canopy includes a canopy fabric and multiple folding canopy frames. Side beams are respectively provided on both sides of the front and rear ends of the inner folding canopy. The vertical support assembly provides vertical support for the inner folding canopy and includes two rope steering seats, two tension springs, multiple support wheels, and ropes. The two rope steering seats and two tension springs are respectively arranged opposite to each other on the side beams located at the front and rear ends. The support wheels are installed one-to-one on the sides of the folding canopy frames. The ropes sequentially connect to and support the multiple support wheels, with both ends of the ropes passing over the two rope steering seats and connected to the two tension springs to tension the ropes. This folding canopy-type inner protective device provides vertical support through its own vertical support assembly, which can be disassembled and replaced separately for easy maintenance.

The utility model relates to the technical field of AGV trolley equipment, in particular to a fork arm adjusting structure of an AGV trolley, a fork arm is connected with a door frame on the AGV trolley through an adjusting assembly, when the tip end of the fork arm warps upwards or droops due to deviation of the fork arm, the relative angle between the fork arm and the door frame can be adjusted to a certain degree through the adjusting assembly, and therefore the fork arm can be adjusted to a certain degree. Therefore, the problem that the tip end of the fork arm upwarps or droops is solved.

The utility model discloses a calendaring device for producing and processing plastic films, which comprises a U-shaped equipment base, an upper calendaring roller is rotatably arranged on the U-shaped equipment base, a main calendaring roller is rotatably arranged on the U-shaped equipment base below the upper calendaring roller, a motor penetrates through the U-shaped equipment base, and the main calendaring roller is rotatably arranged on the U-shaped equipment base. A motor is arranged on the U-shaped equipment base, an output shaft of the motor is fixedly connected with the main calendering roller, a heating equipment cavity is formed in the upper calendering roller, a plurality of groups of independent electromagnetic coils which are axially arranged along the upper calendering roller are embedded in the heating equipment cavity, a cooling water pipe is arranged in the upper calendering roller, and a processing rack is fixedly connected to one side of the U-shaped equipment base. The utility model belongs to the technical field of plastic film production, and effectively solves the problems that when a calendering device for plastic film production and processing is used, the uniformity of calendering processing is easily influenced due to temperature shifting, the heat energy loss is larger, and waste is easily generated.
