The utility model belongs to the field of building construction technology, especially a movable operation platform. Including top subassembly, middle subassembly, adjustable base, sliding device, first support device and second support device, top subassembly sets up in the upside of middle subassembly, adjustable base sets up in the downside of middle subassembly, sliding device is vertically adjustable and sets up in the side of middle subassembly close to adjustable base, first support device rotates and sets up in the side of middle subassembly close to adjustable base, one end of second support device connects top subassembly, and the other end sets up on the ground, first support device includes connecting rod, spring, support wheel and action lever, two connecting rods are connected and rotate and set up on middle subassembly, support wheel sets up in the one end of connecting rod, and the other end is connected with action lever, one end of spring is connected with connecting rod, and the other end is connected with middle subassembly. The operation platform is lifted through first support device, and the operation platform is moved to the place that needs through sliding device, need not to re -erect, simple and convenient.

The application discloses a multi-degree-of-freedom adjusting probe array for battery module equalization detection, and relates to the technical field of battery detection.The multi-degree-of-freedom adjusting probe array comprises a base, a plurality of mounting columns are symmetrically and fixedly installed on the base, an electric telescopic rod is fixedly installed in each mounting column, a supporting frame is fixedly and jointly installed at the telescopic ends of the plurality of electric telescopic rods, a plurality of supporting frames are equidistantly clamped in the supporting frame, and a plurality of fixing cylinders are slidably installed in each supporting frame.The application solves the problem that the existing battery module accumulates position errors in the assembly link, causes small height differences in the height direction of each pole in the same module, and causes the surfaces of some battery poles to present a small inclination after welding, which leads to unstable contact between the probe and the pole, and the pole spacing, pole height and arrangement mode of battery modules of different capacities and specifications are greatly different, the common probe array cannot be flexibly adjusted, and the production line efficiency is seriously affected.

The utility model provides a vector frequency converter cabinet heat radiation structure, which relates to the technical field of electrical equipment heat radiation and comprises a cabinet body, a mounting frame and a heat radiation frame, and heat radiation holes are arranged on two sides of the cabinet body. The cleaning mechanism is arranged in the heat dissipation frame, the motor drives the threaded rod to rotate, and the connecting block drives the cleaning brush to move up and down, so that the cleaning brush reciprocates on the surface of the dustproof filter screen, dust attached to the surface of the dustproof filter screen is swept down, and the dust is prevented from blocking the filter screen to affect ventilation and heat dissipation; meanwhile, a collecting box arranged on the lower surface of the heat dissipation frame is in sliding connection with a convex groove in the side face of the heat dissipation frame through a convex block and can receive dust swept down by a cleaning brush, and when much dust is accumulated in the collecting box, a limiting rod is pulled to be separated from a limiting hole, the tension of a tension spring is overcome, and the dust is prevented from being accumulated in the collecting box; and therefore, the operation is convenient and fast.

The application discloses a connecting structure and method of an implantable pulse generator and the pulse generator. The connecting structure is formed between a feedthrough lead and an antenna. The antenna has an antenna lead-out end which is columnar. The diameter of the feedthrough lead is substantially the same as that of the antenna lead-out end. The antenna lead-out end is arranged along the length direction of the feedthrough lead. The head of the antenna lead-out end and the head of the feedthrough lead are respectively provided with a first bending part and a second bending part. The first bending part and the second bending part are hooked and connected through at least one laser spot welding. The application can better overcome the axial and radial tension through the hooking and welding mode, improve the stability of the connection, and reduce the possibility of falling off, thereby solving the problems that the connection between the antenna and the feedthrough lead of the implantable pulse generator is unstable and easy to fall off in the prior art.

The utility model discloses a double -decked paper towel distributor belongs to public facilities articles technical field. It is to solve the existing double -decked paper towel distributor and paper towel roll is stolen easily, and the problem of partial use paper towel roll replacement waste. The distributor includes at least two compartments, and each compartment has a base, openable cover, paper towel frame and locking device, and locking device contains bracket, locking component, unlocking component, blocking device and biasing device, and bracket moves from external position to internal position with paper towel roll use, and after pushing blocking device, button can make unlocking component and locking component joint and unlock, and it further includes the warehouse door with branch, and branch engages with paper towel roll, and only when the current compartment paper towel roll is exhausted, the warehouse door can slide to next compartment, and it is mainly used in public washroom and other places, can prevent paper towel roll and waste, prolongs continuous paper supply time, and is convenient for timely supplement.
