This utility model discloses an assembly fixture, belonging to the field of assembly fixture technology. It includes a base, an air pump, a pneumatic mechanism, and a connecting arm. The pneumatic mechanism includes a cylinder, a reversing valve, a piston disc, a piston rod, and a three-way valve. The air pump's inlet and outlet are both connected to the reversing valve. Two air passages are connected to the outside of the reversing valve, and the other end of each air passage is connected to a corresponding three-way valve. The connecting arm is rotatably sleeved on the outside of the piston rod. An angle fixing mechanism is provided at the top of the connecting arm to fix its angle. This utility model achieves stable clamping by driving the piston rod with a pneumatic mechanism. The angle fixing mechanism allows for flexible adjustment and quick locking of the connecting arm's angle, significantly improving assembly efficiency and ease of operation. The flexible connecting mechanism, through the synergistic effect of the buffer pad and the connecting shaft, allows the clamping pad to automatically adapt to uneven product surfaces in the vertical and horizontal directions, ensuring uniform and reliable clamping.

The utility model discloses a concrete building material additive weighing device, include: filter box, filter subassembly, including fixed frame and filter plate, and the both sides of fixed frame are equipped with the convex plate respectively, install subassembly, including fixed base and fixed column, and the fixed base and fixed column are equipped with the clearance recess of clearance cooperation with the convex plate, install subassembly still include hollow column, and the hollow column is equipped with the limit block of slideable up and down in, and the fixed column is equipped with the limit slot of cooperation with limit block, when limit block slides into limit slot, and fixed column, filter subassembly and fixed base are locked, when limit block slides out of limit slot, and fixed column, filter subassembly and fixed base are unlocked, to realize the disassembly of filter subassembly. The filter plate is detachably installed on the fixed frame, can be convenient for the filter plate to disassemble replacement, to carry out the maintenance cleaning of filter plate. Through install subassembly can play the installation and disassembly effect to filter subassembly, can be convenient and fast with filter subassembly disassembly take out to carry out the maintenance cleaning.

The utility model discloses a kind of layer board drawer structures, including drawer seat, drawer board, a pair of sliding seat, a pair of sliding frame and drop lock assembly, sliding seat is located on the both sides of drawer seat, sliding frame is located at the bottom end both sides of drawer board, and sliding frame is slidably arranged on sliding seat;Drop lock assembly includes first stop rod, second stop rod and linkage rod, first stop rod and second stop rod movably set at the both ends of sliding frame, one end of linkage rod is fixed with first stop rod, the other end of linkage rod is below second stop rod;The end away from main frame on sliding seat is formed with stop groove, first stop rod or second stop rod can be clamped in stop groove, to limit the movement of sliding frame;The both ends of first stop rod are fixedly provided with pull rod.The utility model is characterized in that the layer board drawer structure can realize automatic drop lock when opening or closing, and the operation process of releasing drop lock is simple.

This application relates to the field of mobile power bank technology, specifically to a cable restraint mechanism and charging device. The cable restraint mechanism includes a housing, a locking member, and a winding assembly. The cable includes a cable body and a plug. The housing has a storage position for storing the plug, and the plug is fixed in position relative to the housing in the lifting direction when in the storage position. The locking member is movably disposed in the housing and has a locked position and an unlocked position for locking the cable body. The winding assembly is used to wind the cable body. In the stored state, the cable body, through the locking member, and the plug, through the storage position, form two stable mechanical connection points with the housing, making the cable body exposed in the housing a handle that can withstand external lifting force, preventing the winding assembly from being pulled out due to tension. After the plug is dislodged from the storage position, it is in an unstored state, releasing the locking member from locking the cable body. The plug and cable body can move freely relative to the housing, facilitating power supply by the user.
