Clamp for leak detection device of solar heat collection box

The utility model relates to a clamp for a leak detection device of a solar heat collection box, and belongs to the mechanical field. The clamp includes an inflation beam which is a tubular member. Two ends of the inflation beam are sealed through welding. Clamping board clamping pieces are disposed on two sides of the inflation beam. Two clamping board clamping pieces clamp on the inflation beam. Two ends of each clamping board clamping piece are provided with through holes, and bolts pass through the through holes and are fixed by nuts, so that the clamping board clamping pieces are tightly clamped on the inflation beam. Clamping board fixing plates are fixed at two ends of the bolts in a direction perpendicular to the inflation beam direction through bolts. Upper ends of the clamping board fixing plate fix the clamping boards in the inflation beam direction without welding to the inflation beam. The clamp for the leak detection device of the solar heat collection box is convenient to observe.
