Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being described further and illustrating.
Embodiment 1
With reference to Fig. 1-5, the present embodiment provides a kind of flashboard rack, comprises a pair cell wall 1, a pair feet 4, a pair adjusting rod 3, a pair adjusting sleeve pipe 2, holds out against screw 6, a pair fixed retaining member and a pair active lock gripping members for a pair.
Fixed retaining member comprises a sleeve pipe 52, and sleeve pipe 52 is provided with row's fixed teeth 51 and row's movable teeth mouth 55, and one end of sleeve pipe 52 is provided with internal thread.Active lock gripping members comprises a motion bar 54, and motion bar 54 is provided with row's movable teeth 53, and one end of motion bar 54 is provided with the external screw thread with screw-internal thread fit on sleeve pipe 52.The sleeve pipe 52 of fixed retaining member is enclosed within outside the motion bar 54 of active lock gripping members, and it is outer and to be partnered clip tooth by a fixed teeth 51 and a movable teeth 53 that movable teeth 53 stretches out sleeve pipe 52 through movable teeth mouth 55, forms retaining mechanism 5.Rotary moveable bar 54 makes motion bar 54 facing sleeve 52 move, and changes motion bar 54 and the relative position of sleeve pipe 52, the distance between fixed teeth 51 and movable teeth 53 is changed, thus regulate the distance in clip tooth between fixed teeth 51 and movable teeth 53 with this.
The top (distance cell wall top is about 50mm) of cell wall 1 is provided with a row folding tooth mouth 11, and sleeve pipe 52 is welded on the region being provided with clip tooth mouth 11, make the clip tooth in retaining mechanism 5 and clip tooth mouth 11 one_to_one corresponding, clip tooth puts in flashboard rack through clip tooth mouth 11.
An adjusting rod 3 is welded respectively in the both sides of a cell wall 1, an adjusting sleeve pipe 2 is welded respectively in the both sides of another cell wall 1, adjusting sleeve pipe 2 arranges screw, adjusting sleeve pipe 2 is made to be enclosed within outside adjusting rod 3, screw 6 will be held out against also inwardly screw through screw, adjusting rod 3 and adjusting sleeve pipe 2 are interfixed, thus fixes the distance between two cell walls 1.When needing the distance between change two cell wall 1, holding out against screw 6 by reverse rotation makes adjusting rod 3 and adjusting sleeve pipe 2 unclamp, then changing adjusting rod 3 is required separation distance with the distance of phase contraposition to two cell wall 1 of both adjusting sleeve pipes 2, again will hold out against screw 6 and inwardly screw.By adjusting rod 3, adjusting sleeve pipe 2 with hold out against cooperatively interacting of screw 6, two cell walls 1 are made to realize mutually stretching installation.Arrange a feet 4 respectively in the lower end of two cell walls 1, be provided with row's draw-in groove in the bottom of feet 4, draw-in groove and clip tooth one_to_one corresponding, for fixing PCB.
When using above-mentioned flashboard rack to fix PCB, the distance of two cell walls 1 is made to meet the length of PCB by changing adjusting rod 3 with the relative position of adjusting sleeve pipe 2, and the distance of often pair of clip tooth in retaining mechanism 5 is adjusted wide, then PCB is inserted in flashboard rack one by one, after sticking with PCB in flashboard rack, motion bar 54 in circumvolve lock set kit 5 makes the movable teeth 53 in clip tooth close to fixed teeth 51, is clamped by PCB to clip tooth.
Because PCB can be stabilized in flashboard rack without the need to bending PCB by this flashboard rack above-mentioned, rear operation can be improved as silk-screen character and shaping efficiency, be convenient to the control of plate curved tube, reduce PCB because of the bent defective scrappage caused of plate, and the flow process of production board being carried out to pressing plate can be reduced.
Above-mentioned flashboard rack also directly can fix the thin central layer of thick copper, does not need to use without the thin central layer of each thick copper in sulphur paper interval, can save production cost.
Embodiment 2
The present embodiment provides a kind of flashboard rack, and the structure of the cell wall 1 of this flashboard rack is slightly different from the structure of the cell wall of embodiment 1, and the structure of other parts is consistent with the structure of the corresponding component of embodiment 1.Cell wall 1 in the present embodiment as shown in Figure 6, an installing port coordinated with sleeve pipe 12 is provided with on the top (distance cell wall top is about 50mm) of cell wall 1, Socket welding is connected on installing port 12 place, the fixed teeth on sleeve pipe and the movable teeth on motion bar (clip tooth namely in retaining mechanism) put in flashboard rack through installing port 12.
Can also adopt the cell wall of other form in other embodiments, retaining mechanism to be fixed on cell wall and clip tooth can be inserted in flashboard rack.
The above only further illustrates technology contents of the present utility model with embodiment; so that reader is easier to understand; but do not represent execution mode of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreation, all by protection of the present utility model.
