Abstract

The utility model relates to a right angle connector structure for door frames. A connecting solid body with a shape a little similar to a trapezoidal taper is arranged at the upper end of a corner on the outer side of a door frame, and a lower end connector is provided with a slot which is in a half open type and inwards extends to form a circular arc long shape. A column groove is arranged in the circular arc-shaped long slot in advance for the arrangement of an inlaying column, and the middle section of the inlaying column is provided with an oblate disk-shaped flange. A connector at the upper end of a corner on the inner side of the door frame is provided with a conical slotted hole In a penetrating mode, and an iron sheet which is used for the extension and penetration of a screw bolt and is provided with a conical slotted hole is fixed with a circular button pull handle on the other side of the connector. When door frames on the left and the right sides of the circular button pull handle are closed, through the magnetic combining action of a magnet and the iron sheet, the fixation and the tight closure are achieved, and screw nails can not be exposed to hurt users. The utility model not only has the function of easily and rapidly fixing a door frame and a frame body by using light force in assembly, but also can extend the service life and improve the practical efficacy of the right angle connector structure for door frames.

Description

Doorframe angle coupling structure

Technical field

The utility model relates to a kind of doorframe angle coupling structure, refer in particular to a kind of being arranged on the rack, and have and well accept doorframe keying function, make to have light function in the assembling, and then promote the application life and the practical effect of doorframe angle coupling.

Background technology

Consult Fig. 7-shown in Figure 8, the tradition rack, be to form with 94 windings of at least two door-plates by most joints 91, most adapter 92, most side plate 93, the coupling assembling 95 that lower end on the corner, door-plate 94 outside links is preset with an inward recess 951, projections 96 so that kink is dashed forward and established in upper and lower two adapters 92 can freely rotate by projection 96 two door-plates 94 for the center.Its major defect is:

Because of the socket of inward recess 951 and projection 96 is strong jerky urgent combinations, cause two door-plates 94 installing, and even all very trouble and inconvenience in the dismounting.

Summary of the invention

The purpose of this utility model provides a kind of doorframe angle coupling structure, overcomes the drawback of prior art, reaches and well accepts the purpose that doorframe opens and closes function and promotes the application life of doorframe angle coupling.

The purpose of this utility model is achieved in that a kind of doorframe angle coupling structure, and it is characterized in that: four corner ends of doorframe respectively are provided with joint, and the lateral joint upper end is provided with the slightly seemingly binding entity of ladder taper shape; The right angle end of the entity of following end joint is provided with opening port, and a side of this opening port forms passage, is provided with the diameter cylinder groove bigger than this width of channel in this passage; The entity of Connection Element is to have disc, and the embedding post that extends axially two different bores and the pivot post of this disc, the pivot post of this Connection Element are articulated in the set circular hole place of body, support body below, and this embedding post is to be embedded in the cylinder groove of this joint; The last end joint in the inboard corner of doorframe is equipped with the circular cone slotted eye, with screw stretch through iron plate with circular cone slotted eye and this joint in addition side round button pull handle be screwed fixingly, the magnetite on this iron plate and this support body magnetic mutually closes fixing.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

The specific embodiment

Consult Fig. 1-shown in Figure 2, rack D of the present utility model is that four corner ends in doorframe A are provided with joint, be provided with one slightly like the terraced binding entity 4 of tieing up shape in lateral joint 1 upper end, the right angle end of the entity of following end joint 2 is provided with an opening port 21, form a passage 22 by this opening port 21 toward a side, in this passage 22, be provided with the diameter cylinder groove 23 bigger than the width of this passage 22.

The entity of Connection Element 3 is to have a disc 31, extend axially the embedding post 32 and the pivot post 33 of two different bores by disc 31, this Connection Element 3 is to utilize pivot post 33 to be articulated in set circular hole 84 places of support body below body 83, and embedding post 32 then is to be embedded in the cylinder groove 23 of aforementioned joint 2.

Upper end, the inboard corner joint 5 of doorframe A is equipped with a circular cone slotted eye 51, by the screw 52 identical iron plate 6 that stretches through with circular cone slotted eye 61, and be screwed fixing with other side round button pull handle 7 of joint, magnetite 8 on this iron plate 6 and support body D magnetic mutually closes fixing, when left and right sides doorframe plate body is closed, reach the effect that fixedly closes.

Aforementioned joint 5 and iron plate 6 are equipped with the circular cone slotted eye, screw 52 head ends are hidden in the slotted eye, in the doorframe opening-closing process, can never scratch staff, allow iron plate 6 and magnetite 6 have more magnetic area firm increasingly (screw head end evagination then only allow screw head end and magnetite magnetic mutually) simultaneously.

Consult Fig. 3-shown in Figure 6, when the utility model in when assembling, the ladder taper shape of doorframe A lateral joint upper end is linked in the circular hole 82 of top body 81 that entity 4 inserts support bodys earlier, opening port 21 by joint 2 supports the embedding post 32 that closes the Connection Element 3 in being hubbed at below body 83 circular holes 84 again, doorframe A is a little firmly passed in support body, make the cylinder groove 23 of joint be embedded in embedding post 32 via passage 22, form fixing.Upper and

lower body

81,83, respectively with link entity 4, Connection Element 3 mutually pivot close, doorframe A is that movable freely opens and closes, by the magnetic effect of iron plate 6 and magnetite 8, doorframe A can be by switch firmly.

In sum, the structure of joint 2 of the present utility model, make doorframe A be assembled in support body D easily, and can free activity open and close, in addition, doorframe A is is stably opened and closed, it would be desirable that screw 6 can evagination by the absorption of iron plate 6 with magnetite 8, in use scratch staff and be unlikely, the utility model obviously has novelty, creativeness and practicality.
