The backing plate rack that this embodiment provided is used for the locking backing plate, prevents that the backing plate from throwing away. The dunnage support of this embodiment is shown in fig. 1 and 2. The locking function of the base plate placing frame is realized by the up-and-down movement of the blocking piece 4, namely the blocking piece 4 moves up and down in the sliding groove 8 to realize the shielding and opening of the taking and placing opening. In order to make the use of the cushion plate placing frame of the embodiment more convenient, the embodiment adopts the elastic sheet with the wave-shaped section to limit the stopper 4, and the specific operation is as follows: when pressing the shell fragment, the shell fragment takes place deformation, keeps off piece 4 alright freely to pull up the promotion along with moving part 6, when moving part 6 lifted to the top, stops pressing the shell fragment this moment, and the shell fragment resets, and the arch of shell fragment supports and keeps off piece 4, and the restriction keeps off the reciprocating of piece 4, so far realizes the function of opening of backing plate rack. When pressing the wave shell fragment once more, the shell fragment takes place deformation once more, keeps off piece 4 this moment and can follow moving part 6 free fall, when keeping off 4 whereabouts to the lowest position, stops pressing the wave shell fragment this moment, and the shell fragment resets, and the sunken joint of shell fragment keeps off 4 sides in keeping off, and the restriction keeps off the reciprocating of piece 4, so far can realize the function of closing of backing plate rack.

The support member 202 of the tie plate placing rack of this embodiment is made of square steel material, and is welded by being obliquely welded to each other to form a closed-loop frame structure, so that the overall rigidity is high, and the cross beam 2022 and the reinforcement beam 2028 are welded to the connection plate 2026, so that the overall rigidity of the tie plate placing rack is further enhanced, and resonance is not easily generated.

The limiting plate 206 of this embodiment is formed by bending three surfaces of the plate body 204 in the same direction, welding gaps between the three surfaces, bending the other surface in the opposite direction to form a reinforcing plate 208, and further welding an angle plate 210 at a corner of the bottom bending, wherein the reinforcing plate 208 and the welding angle plate 210 are designed to enhance the bearing rigidity of the mounting bracket 2.

The cross beam 2022 and the reinforcement beam 2028 are welded to the connection plate 2026, the vertical beam 2024 is welded to both ends of the cross beam 2022, wherein the reinforcement beam 2028 is welded to the vertical beam 2024 to form a closed loop structure, the connection mode is as shown in fig. 9, and the welding mode between the beams adopts oblique butt-ring welding to finally form a closed loop type framework.

Plate body 204 is welded to cross beam 2022 by plug welding, wherein three edges of plate body 204 are curled, and the seam between the curled edges is welded to form a three-sided limiting plate 206, the reverse side of the other edge is bent to form a reinforcing plate 208, an angle plate 210 can be welded at the included angle between reinforcing plate 208 and plate body 204 to reinforce the supporting strength of plate body 204, and the bottom plate is formed into an integrated rib plate by bending the upper and lower surfaces.

The movable member 6 includes: handle, connecting rod and bolt. The plate body 204 and the vertical beam 2024 are formed, a through hole 10 is arranged on the plate body 204, a sliding groove 8 is arranged on the limiting plate 206, two ends of the blocking piece 4 are inserted into the sliding groove 8 of the limiting plate 206, one end of the connecting rod penetrates through the through hole 10 on the plate body 204, is connected to the blocking piece 4 through a bolt, is connected with the blocking piece 4 into a whole, forms an up-and-down moving pair with the plate body 204, and one end of a wavy elastic sheet is connected to the plate body 204 or the vertical beam 2024 and is arranged on.

The working principle of this embodiment is as follows:

the locking function of the underlay holder is determined by the position of the moving element 6 and the stop 4. The operation of its locking function is as follows: pressing wavy shell fragment and keeping, then upwards lifting and pulling moving part 6, keeping off piece 4 and rising along with moving part 6 together, keeping off the coincidence of piece 4 upper flat and plate body 204 lower flat, loosening the shell fragment this moment, the shell fragment resets, supports and keeps off piece 4, and the backing plate rack is open state this moment, can put into the backing plate rack with the backing plate level. After the backing plate inserted in the box, press the wave shell fragment, then moving part 6 with keep off 4 can free fall, when keeping off the contact of

piece

4 and 8 bottoms of spout, no longer move down promptly, relax the shell fragment, the spacing portion 1202 joint of shell fragment keeps off 4, the backing plate rack just gets into the locking state this moment, the backing plate can not be pulled out to realize the locking effect of backing plate.

This embodiment has the following advantageous effects:

1. the utility model discloses a backing plate rack whole size is little, simple structure, does not occupy unnecessary space.

2. The lifting moving part is adopted to drive the blocking part to move so as to realize the locking of the base plate, and the locking device is simple in structure, convenient to use, stable and reliable.

3. Adopt the design of wavy shell fragment, possess two limit function.

4. The supporting piece is arranged on the closed-loop framework, the supporting piece is connected with the connecting plate through the double beams, the beams are connected through the oblique welding rings, the overall rigidity of the supporting piece is high, and resonance is not easy to generate.

5. The plate body and the limiting plate integrated structure have high mechanical strength.
