The image effect of the multi-camera module prepared by this application is equivalent to that of the module produced by the COB packaging process, but it avoids the use of bonding gold wires in the traditional COB packaging process, and the investment in production line equipment is less, and the manufacturing cost is lower; The size of the entire multi-camera module is conducive to the development of the multi-camera module toward miniaturization.

The invention discloses a water pump cushioning board. The water pump cushioning board comprises a cushioning board body used for installing a water pump on an engine body. The cushioning board body is provided with a water pump installation plate, and a fan installation plate is arranged at the part, on one side of the water pump installation plate, of the cushioning board body. The water pump cushioning board is light in mass, high in strength and good in universality, can be used for installing the water pump and a fan assembly, guarantees the arrangement reasonability of the water pump and the fan assembly and reduces the number of special parts for installing an engine assembly, and installation stress exerted on installation planes of the water pump cushioning board and the engine body is small.

The invention relates to the field of fluid pressure regulating valves, in particular to an improved valve operating mechanism for a film actuated pressure regulating valve. The invention discloses a diaphragm actuated pressure regulating valve for connecting a gas source under pressure and a user end, which comprises an input port with an axis, a valve element coaxial with the input port and a valve element controlled by a diaphragm. A ball and cam valve element actuator in which the membrane is perpendicular to and coaxial with the input port.

The invention relates to the technical field of vehicle assembly part detection, and especially relates to a vehicle body fixation device. The vehicle body fixation device comprises a pressing element, a cylinder and a fixation arm. The pressing element has a three-frame structure. A first frame and a second frame which are opposite to each other are fixed on two sides of the cylinder respectively through a middle shaft. The pressing element is rotated around the middle shaft. The fixation arm is located inside the cylinder. One end of the fixation arm is provided with a compacting hook, and the other end of the fixation arm is connected with the cylinder through a lower shaft. The pressing element is rotated around the middle shaft to drive the swing of the fixation arm to make the compacting hook pressed onto the vehicle body floor so as to make the vehicle body floor and the detection surface maintained in the stationary state, so that the distance between the vehicle body floor and the detection surface in the vehicle body detection process can be eliminated to realize the clinging of the vehicle body floor and the detection surface, so the data detection accuracy and stability can be ensured.

The invention provides a static electricity and dust removal device for electromechanical equipment, which includes a frame, a stand, a control switch, a supporting leg, a movable caster, a connecting bushing, a fixing nut, a supporting screw, a hand wheel, a supporting base and an anti-skid pad. The arrangement of the connecting seat, high voltage generator, ion air gun, fixed sleeve, adjusting rod, adjusting bolt and static elimination contact block of the present invention is beneficial to eliminate static electricity generated by electromechanical equipment, and can be carried out according to the size or installation position of the electromechanical equipment. Loosen the adjusting bolt, adjust the distance between the fixed sleeve and the adjusting rod, so that the static electricity elimination contact block contacts the surface of the electromechanical equipment, and then lock the adjusting bolt, if the electromechanical equipment generates static electricity, the static electricity can be exported, and at the same time, the ion is controlled by the high voltage generator The action of the air gun can generate ion wind, which can blow the dust on the surface of the electromechanical equipment and remove static electricity at the same time to ensure the stability of the electromechanical equipment.

The invention relates to a colored tape box used for a printer. The colored tape box comprises a shell body, a drive wheel, a driven wheel and a lever piece. Before the colored tape box is used for a first time, a clamping portion of the driven wheel and a clamping portion of the drive wheel do not make contact, and therefore the situation that the clamping portion of the drive wheel and the clamping portion of the driven wheel abut against at one point for a long time and deform or are damaged to be sticky can be avoided. When the colored tape box is used, after the drive wheel rotates, the driven wheel is driven by a gear part to rotate together with the drive wheel. Due to the fact that the lever piece which is fixedly arranged in the shell body is arranged between gear parts of the driven wheel in a penetrating mode, the driven wheel moves with the lever piece as a supporting point. After the driven wheel is separated from the lever piece, the driven wheel is continuously driven by the gear part of the drive wheel, so that the clamping portion of the drive wheel and the clamping portion of the driven wheel gradually abut against to clamp colored tapes. The colored tape box can remove the space distance between the clamping portion of the drive wheel and the clamping portion of the driven wheel without manual operation, improve use convenience, simplify the structure, reduce the number of assemblies, and greatly reduce cost.
