Dynamic cooperation.
By using such scheme, by the position-limit foot of angled slide block to angled slide block at the glide direction upper limit of chute, keep away
Exempt from angled slide block excessive by the reseting elasticity of spring, cause two pieces of clamping plates to collide, make lower the service life of clamping plate.
Improve further and be set to: described main body two ends are provided with rotating shaft and projection, and described rotating shaft is provided with baffle plate, institute
Stating baffle plate one end to fix with rotating shaft, the other end abuts with projection.
By using such scheme: when inserting pcb board, gear can be made by the baffle plate rotation that rotating shaft rotarily drives in rotating shaft
Plate props up with projection, pcb board can be made will not to skid off in clamping plate, preferably fix pcb board.
Improve further and be set to: between described rotating shaft and baffle plate, be provided with torsion spring.
By using such scheme, being acted on by torsion spring can be automatically after the reset revolving force of baffle plate can make baffle plate be opened
Reset, the most preferably conflict with pcb board, do not shake.
This utility model in sum, when inserting the pcb board of different-thickness, spring can be according to various sizes of pcb board
Flexible, change the distance between two pieces of clamping plates, make pcb board be inserted between clamping plate, simultaneously the reseting elasticity of spring
Acting on clamping plate, clamping plate is fixedly clamped pcb board, thus reaches the PCB using same subrack just can place different-thickness
The purpose of plate, is provided with towards the chamfering inside two pieces of clamping plates further through clamping plate two ends, when pcb board inserts, and can be along
Clamping plate is gradually pushed open by the chamfering on clamping plate to both sides, makes, between the insertion clamping plate of pcb board energy smoothness, to work as needs simultaneously
When taking out pcb board, can by arrest at the chamfering of clamping plate pcb board expose one jiao of clamping plate by pcb board extraction, facilitate PCB
The dismounting of plate.

Detailed description of the invention
The variable-sized insertion box guidance rail embodiment a kind of to this utility model that see figures.1.and.2 is described further.
A kind of variable-sized insertion box guidance rail, including main body 1, described main body 1 offers groove 6, arranges in described groove 6
Having two pieces of clamping plates 3 parallel to each other, described clamping plate 3 is parallel with groove 6 sidewall, arranges between described clamping plate 3 and sidewall
There is spring 8.
Described clamping plate 3 two ends are provided with towards the chamfering inside two pieces of clamping plates 3, and described groove 6 sidewall offers
Several chutes, described spring 8 is fixed in chute, and described spring 8 is provided with angled slide block 2, the corresponding spring of described angled slide block 2
The other end of 8 is fixed with clamping plate 3, and described angled slide block 2 is connected with slide, described chute at least two, described chute
Being uniformly distributed on groove 6 sidewall longer sides direction, described clamping plate 3 part hollow out, described angled slide block 2 includes connector 10 He
Position-limit foot 9, described chute includes inside groove and water jacket, and described inside groove aperture area is more than water jacket aperture area, described position-limit foot 9 with
Inside groove is slidably matched, and described connector 10 is slidably matched with water jacket, and described main body 1 two ends are provided with rotating shaft 5 and projection 7, described
Being provided with baffle plate 4 in rotating shaft 5, described baffle plate 4 one end is fixed with rotating shaft 5, and the other end abuts with projection 7, described rotating shaft 5 and baffle plate
Torsion spring it is provided with between 4.
Chute on preferred each groove 6 sidewall of the present embodiment is provided with two, the line between rotating shaft 5 and projection 7
Parallel groove 6 bottom surface and higher than groove 6 bottom surface, when subrack needs to insert various sizes of pcb board, first by the gear in rotating shaft 5
Plate 4 rotates a certain angle, and makes pcb board can insert along the chamfering on clamping plate 3, and now clamping plate 3 stress is gradually to both sides
Opening, angled slide block 2 stress is pressed in chute, and spring 8 is compressed, and owing to spring 8 is in chute, not with extraneous contact, makes bullet
Spring 8 is not easy to get rusty, the most attractive in appearance, and when the enough pcb boards of distance between clamping plate 3 insert, pcb board inserts clamping plate
In 3, the reseting elasticity of the spring 8 in two chutes acts on the angled slide block 2 of correspondence simultaneously, makes angled slide block 2 act on clamping plate 3
Uniform power, make two pieces of clamping plates 3 be fixedly clamped by pcb board, now unclamp baffle plate 4, and baffle plate 4 is by the reset revolving force of torsion spring
Effect resets, and is propped up by pcb board, and during pcb board work simultaneously, the openwork part on clamping plate 3 can make pcb board preferably dispel the heat.
When pcb board changed by needs, baffle plate 4 is rotated a certain angle, at the chamfering by clamping plate 3, arrests pcb board
Being extracted out by pcb board for one jiao that exposes clamping plate 3, now spring 8 resets and is ejected by angled slide block 2, pushes up as shown in Figure 2 in ejection process
Angled slide block 2 is blocked by the position-limit foot 9 going out block 2, and spring 8 is in chute during full extension, and two pieces of clamping plates 3 fail contact and touch
Hitting, finally unclamp baffle plate 4, baffle plate 4 is resetted by the reset revolving force of torsion spring, completes pcb board and removes and installs process.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
