Abstract

The utility model discloses a self-locking type concealed hinge with a sliding block. The self-locking type concealed hinge comprises main parts including a middle shaft, a first hinge base, a first guiding rail block, a second hinge rod, a first hinge rod, a second guiding rail block and a second hinge base. One end of the first hinge rod is hinged to the first guiding rail block via a side shaft hinge and the other end of the first hinge rod is connected with the second guiding rail block is via a sliding block lock head. One end of the second hinge rod is hinged to the second guiding rail block via a second side shaft hinge and the other end of the second hinge rod is connected with the first guiding rail block via the sliding block lock head. The first hinge base is connected with the first guiding rail block in a fastening mode via a first inside hexagonal bolt. The second hinge base is connected with the second guiding rail block in a fastening mode via a second inside hexagonal bolt. The first hinge rod and the second hinge rod are hinged via the middle shaft and distributed in a centrosymmetric mode. The self-locking type concealed hinge with the sliding block has following beneficial effects: when the hinge is applied to a folding device, the effect of automatically locking the position when the hinge is expanded at 90 degrees or 180 degrees is brought about; the hinge is concealed in the folding device when being expanded; and therefore a problem of a non-concealed type overlarge gap of the hinge is mitigated.

Description

Slide block self-locking concealed hinge

Technical field

The utility model relates to the concealed hinge using on a kind of folding device, the slide block self-locking concealed hinge particularly using in a kind of Collapsible house.

Background technology

Hinge claims again hinge, is for connecting two solids and allowing the mechanical device rotating between the two.On current market, there is no a can be for the concealed hinge of the fixed angle self-locking on the folding devices such as folded form house.The utility model is not increasing under the prerequisite of manufacture, installation difficulty, reach following effect: the integral outer appearance and the globality that have maintained folding device (as door, window and folding wall etc.), after expansion reaches self-locking position, overall structure is stable, solve the excessive problem in gap, convenient for unlocking, also has the feature that processing and maintenance cost are low.

Utility model content

The utility model is intended to be used in foldable wall on customer service Collapsible house, door and window, back-flap hinge on roof upon deployment cannot self-locking, cannot make whole device reach stable, and after launching, gap is excessive, affect result of use and problem attractive in appearance, the slide block self-locking using in a kind of folding device concealed hinge is provided.

The present invention realizes in the following manner: described slide block self-locking concealed hinge, comprises axis, hinge base one, way block one, hinge bar two, hinge bar one, the second-class major part of way block two and hinge base; Wherein one end of hinge bar one by side shaft cut with scissors one with way block one hinged, the other end is connected with way block two by a slide block tapered end; One end of hinge bar two by side shaft cut with scissors two with way block two hinged, the other end is connected with way block one by slide block tapered end; Hinge base one is fastenedly connected by hexagon socket head cap screw one with way block one, and hinge base two is fastenedly connected by hexagon socket head cap screw two with way block two; Hinge bar one is hinged by axis with hinge bar two, and distribution is centrosymmetric; On way block one and way block two, be respectively equipped with 90 ° of self-locking holes and 180 ° of self-locking holes simultaneously.In the time that the slide block tapered end of two hinge bar ends slips into respectively in self-locking hole, total will lock; The slide block tapered end of simultaneously pressing two hinge bar ends makes it skid off self-locking hole, can be by total release.

The utility model compared with prior art, has following apparent substantive distinguishing features and advantage: in the time that hinge expands into fixed angle (as 90 °, 180 °), whole mechanism locks to reach stable by oneself; In the time of the duty (180 °) of launching completely, can make hinge be hidden in device, in order to avoid affect result of use and attractive in appearance, avoid whole device gap excessive.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the overview of the utility model while expanding into 90 °.

Fig. 2 is the overview of the utility model while being folded into 0 °.

Fig. 3 is that the utility model expands into the overview of 180 °.

Fig. 4 is slide block lock partial enlarged drawing of the present utility model.

Detailed description of the invention

Shown in Fig. 1 to Fig. 3, for this slide block self-locking concealed hinge, it comprises axis (1), hinge base one (2), way block one (3), hinge bar two (4), hinge bar one (5), way block two (6), the major parts such as hinge base two (7), described hinge bar one (5), cuts with scissors one (10) hingedly with way block one (3) by side shaft, the other end is connected with way block two (6) by slide block tapered end (14); Described hinge bar two (4), cuts with scissors two (11) hingedly with way block two (6) by side shaft, the other end by slide block tapered end (14), is connected with way block one (3); Hinge base one (2) is fastenedly connected by hexagon socket head cap screw one (8) with way block one (3), hinge base two (7) is fastenedly connected by hexagon socket head cap screw two (9) with way block two (6), simultaneously, hinge bar one (5) is hinged by axis (1) with hinge bar two (4), and distribution is centrosymmetric; As shown in Figure 4, the end slide block mechanism of hinge bar two (4) is made up of slide block tapered end (14), slide block lock inner spring (15) and slide block locked cock (16) and its end self, and the end slide block form of hinge bar one (5) is identical with hinge bar two (4).

As shown in Figure 2, in order to reach the object of self-locking, upper at way block one (3) and way block two (6), be respectively equipped with 90 ° of self-locking holes (13) and 180 ° of self-locking holes (12).In the time that the slide block tapered end (14) of two hinge bar ends slips into respectively in self-locking hole, total will lock; Make it skid off self-locking hole by sliding block tapered end (14), can be by total release.

When the utility model is installed and used, hinge base one (2), hinge base two (7) are fastenedly connected on folding device by screw, rivet etc.

When original state (being folded into 0 °), as shown in Figure 2, now folding device is in folded state.

While being opened into half expansion (90 °) state, there is self-locking in mechanism, and as shown in Figure 1, now slide block lock one (5), slide block lock two (6) slip into respectively in 90 ° of self-locking holes; The slide block tapered end (14) of simultaneously pressing two hinge bar ends with hand can release, as shown in Figure 4.

Continue to be launched into 180 ° of states, as shown in Figure 3, now again by self-locking, whole hinge will be hidden in folding device simultaneously; Unlocking manner during with 90 ° of states release identical.
