Abstract
The utility model provides a cam -type computer extension screen port connecting device, including the stitch shell, characterized by: be provided with the stitch in the stitch shell, stitch connecting circuit board, circuit board downside is provided with the cam, the cam axle center is passed by wheel hub, wheel hub passes through general flat key and connects the cam, wheel hub one end is passed through the connecting rod and is connected the pivot, the wheel hub other end is fixed through the split pin on the stitch shell, the last fixing bolt that is provided with of wheel hub, the downside of circuit board is provided with 4 and returns the spring that contracts, it is in to return the spring coupling that contracts on the stitch shell. The utility model discloses a rotation of pivot to drive wheel hub and rotate, under general flat key's drive, make the cam promote the circuit board and shift up, thereby make on the stitch inserts the computer link mouth, adopt cam mechanism, simple structure, compactness.
Description
Technical field
The utility model structure relates to computer realm, especially a kind of cam-type computer expansion screen port connecting apparatus.
Background technology
Computer expansion screen refers on the basis of the original display of computer, is connected, for computer provides another one display screen by the connection stitch of display screen with computer, be called expansion screen, thus realize double screen operation at work, and need not switch operating window again, increase work efficiency.Conventional computer monitor adopts stitch to be connected with main frame usually, connected mode adopts and manually assigns, and owing to being provided with 15 stitch in stitch head, socket that is easy and computer misplaces when mounted, to such an extent as to insert inaccurate, assign often and just caused the distortion of stitch even to damage.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of cam-type computer expansion screen port connecting apparatus, overcomes the problem of the installation inconvenience of traditional monitor stitch.
The utility model adopts following technical scheme to realize utility model object:
A kind of cam-type computer expansion screen port connecting apparatus, comprise stitch shell, it is characterized in that: in described stitch shell, be provided with stitch, described stitch connecting circuit board, cam is provided with on the downside of described circuit board, described cam axle center is passed by wheel hub, described wheel hub connects described cam by general flat key, described wheel hub one end is by connecting rod connection rotating shaft, the described wheel hub other end is fixed on described stitch shell by split pin, described wheel hub is provided with set bolt, the downside of described circuit board is provided with 4 retraction springs, described retraction spring is connected on described stitch shell.
As the further restriction to the technical program, described circuit board connects electric wire.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is by the rotation of rotating shaft, thus drive hub rotation, under the drive of general flat key, make cam promote circuit board moves, thus make stitch be inserted on computer connector, set bolt is close to stitch shell and tightens, the fixing employing cam mechanism of realizing circuit plate, structure is simple, compact.The utility model circuit board lower end is provided with a retraction spring, and after cam turns over peak, retraction spring drives circuit board to move down, make stitch divorced from computer connector, under the drive of retraction spring, make circuit board maintenance level in decline process, thus avoid the distortion of stitch.The utility model structure is simple, safe and reliable, has good market prospects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left view of the present utility model.
In figure, 1, stitch shell, 2, stitch, 3, circuit board, 4, cam, 5, wheel hub, 6, connecting rod, 7, rotating shaft, 8, split pin, 9, general flat key, 10, electric wire, 11, retraction spring, 12, set bolt.
Embodiment:
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1 and Fig. 2, the utility model comprises stitch shell 1, stitch 2 is provided with in described stitch shell 1, described stitch 2 connecting circuit board 3, cam 4 is provided with on the downside of described circuit board 3, described cam axle center is passed by wheel hub 5, described wheel hub 5 connects described cam 4 by general flat key 9, described wheel hub 5 one end is by connecting rod 6 connection rotating shaft 7, described wheel hub 5 other end is fixed on described stitch shell 1 by split pin 8, described wheel hub 5 is provided with set bolt 12, the downside of described circuit board 3 is provided with 4 retraction springs 11, described retraction spring 11 is connected on described stitch shell 1.
Described circuit board 3 connects electric wire 10.
The utility model is by the rotation of rotating shaft 7, thus drive wheel hub 5 to rotate, under the drive of general flat key 9, cam 4 is made to promote circuit board 3 moves, thus make stitch 2 be inserted on computer connector, set bolt 12 is close to stitch shell 1 and tightens, fixing of realizing circuit plate 3, adopt cam mechanism, structure is simple, compact.
The utility model circuit board 3 lower end is provided with 4 retraction springs 11, after cam 4 turns over peak, retraction spring 11 drives circuit board 3 to move down, make stitch 2 divorced from computer connector, under the drive of 4 retraction springs 11, make circuit board 3 maintenance level in decline process, thus avoid the distortion of stitch.The utility model structure is simple, safe and reliable, has good market prospects.
