Abstract

The utility model relates to a self-locking type hinge, which comprises a driving component, a shell body, a slide block and a clamping hook part. The shell body and the driving component can be rotationally pivoted, and the shell body is provided with an opening which is formed on the wall surface of the shell body. The slide block can be movably arranged in the shell body, and the contact of the slide block and the driving component is always kept. The clamping hook part is arranged in the opening, can be moved to be extended outside the shell body, or can be extended into the shell body. The slide block can be moved by the driving component, and the slide block is butted with the clamping hook part to avoid that the clamping hook part is retracted into the shell body.

Description

Self-locking hinge

Technical field

The utility model relates to a kind of self-locking hinge, relates in particular to a kind of slide block that utilizes and comes the contact hook part, to prevent the self-locking hinge of hook part retraction.

Background technique

Scanner, duplicating machine and multifunctional paper feeding machine etc. on the market all need use hinge to finish the operation of raising and covering of flip at present.Because consider the assembling convenience of flip and the diversity of scanning document,, but obtain the degrees of freedom that can up move by being plugged in hinge in the body so flip normally can fully firmly not be fixed on the body by hinge.For example, when the scanning books, the end that flip is connected with body can make to become parallel with this scanning platform when flip covers on having the books of specific thicknesses, to obtain high-quality scan-image a little toward rising.Therefore, the flip that is easy to break away from body might break away from body and drop and damage or wound the people under the situation of for example handling process or improper use.

In addition, when flip covers and body when being squeezed, flip also is easy to break away from fully body, therefore also causes both collisions in handling process and the anxiety of the damage of causing is arranged.

The model utility content

Therefore, a purpose of the present utility model provides a kind of self-locking hinge device, and it under situation that can cover at the flip and the body of scanner, prevents fully that flip breaks away from body arbitrarily and the situation that causes separating under the situation that for example is applied to scanner.

For reaching above-mentioned purpose, the utility model provides a kind of self-locking hinge, comprises driven unit, housing, slide block and hook part.Housing and driven unit articulate rotationally, and have the opening on the wall that is formed on housing.Slide block is arranged in the housing movably, and keeps in touch with driven unit all the time.Hook part is arranged in the opening, and removable stretch out outside the housing or the retraction housing within.The removable slide block of driven unit makes slide block contact hook part to avoid within the hook part retraction housing.

By above-mentioned self-locking hinge is applied to scanner, when flip covers, make flip can't break away from body arbitrarily fully; When flip was opened, flip also can't break away from body.When the scanning books, the flip that covers can be raised.Therefore, self-locking hinge of the present utility model can satisfy user's diversified demand, and the situation of avoiding flip to break away from body arbitrarily simultaneously takes place.

Embodiment

Below be that example illustrates self-locking hinge of the present utility model with the scanner.

Fig. 1 and 2 shows that respectively self-locking hinge of the present utility model is at the schematic perspective view of unlatching with closed state.Fig. 3 and 4 shows that respectively self-locking hinge of the present utility model is at the part sectioned view of unlatching with closed state.As shown in Figure 1, self-locking hinge 1 of the present utility model comprises driven unit 10, housing 20, slide block 30 and hook part 40.Driven unit 10 normally is mounted on the flip (not shown) of scanner.Housing 20 normally is mounted on the body 2 (Fig. 3 and 4) of scanner.

Housing 20 is articulated in pivot 11 rotationally with driven unit 10.Housing 20 be formed with guide groove 22 and in fact with the opening 24 of guide groove 22 vertical connections.Opening 24 is formed on the wall 21 of housing 20.In Fig. 1 and 2, wall 21 is positioned at the side of housing 20, and is a vertical surface.

The direction that the bearing of trend of guide groove 22 and housing 20 plug to the body 2 of scanner is parallel.Slide block 30 is arranged in the housing 20 movably, and keeps in touch with driven unit 10 all the time.In the present embodiment, slide block 30 keeps in touch with driven unit 10 all the time by two springs 50 that contact with housing 20, make driven unit 10 and slide block 30 can be effectively the application of force mutually, and two springs 50 lay respectively at the both sides of slide block 30.Perhaps, use single spring 50 or even do not need spring also can reach effect of the present utility model.Perhaps, utilize the special construction design of slide block and driven unit, also can make both remain contact, (form-closed cam) is the same with the combination of driven member just as external form closed type cam.

Hook part 40 is arranged in the opening 24.Hook part 40 can be moved and stretch out outside the housing 20 or within the retraction housing 20.Driven unit 10 removable slide blocks 30 make slide block 30 contact hook parts 40 to avoid within the hook part 40 retraction housings 20.For example, when slide block 30 was not subjected to driven unit 10 extruding, hook part 40 can be moved and stretch out outside the housing 20 or within the retraction housing 20; And when driven unit 10 extruding slide blocks 30, slide block 30 contact hook parts 40 are to avoid within the hook part 40 retraction housings 20.

In the present embodiment, when the angle of driven unit 10 and housing 20 is essentially 90 when spending, just under the situation that the flip and the body of scanner covers, driven unit 10 moving sliders 30 make slide block 30 contact hook parts 40, shown in Fig. 2 and 4.In this case, hook part 40 is arranged in the draw-in groove 3 of body 2 originally, and when housing 20 was up mentioned, hook part 40 can be subjected to the restriction of draw-in groove 3 and housing 20 can't up be moved again.In this case, exactly when the flip of scanner covers, flip can't separate fully with body 2, and flip is connected on the body 2 securely.

When the angle of driven unit 10 and housing 20 is spent (can look demand and variation between 90 and 180 degree) greater than 145 in fact, just under the flip and the non-situation about covering of body of scanner, hook part 40 can be moved via in the opening 24 retraction housings 20, shown in Fig. 1 and 3.That is, when flip started, the user just might use the inside contact of hook part 40 toward housing 20 draw-in groove 3 that makes hook part 40 no longer hook body 2, and flip can be broken away from fully with body 2.

Therefore, in the scanner of using self-locking hinge of the present utility model, when flip covered, flip can't break away from body arbitrarily fully, and when flip was raised, flip also can't break away from body arbitrarily fully.When the scanning books, the flip that covers can be raised.Therefore, self-locking hinge of the present utility model can satisfy user's diversified demand, and the situation of avoiding flip to break away from body arbitrarily simultaneously takes place.

The specific embodiment that is proposed in the detailed description of preferred embodiment is only with so that illustrate technology contents of the present utility model, and be not with the utility model narrow sense be limited to the foregoing description, the many variations of being done under the situation that does not exceed spirit of the present utility model and following claims is implemented, and all belongs to scope of the present utility model.
