Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

a novel door panel locking device and a locking method thereof, as shown in figures 1-2 and 7. Including door frame 1 and the right side articulate interior door 2 on door frame 1, the left side, the upside and the downside of door frame 1 are inlayed and are had with the communicating Contraband template 3 of door frame 1 inner ring, are provided with the picture peg 4 of seting up the jack in the Contraband template 3, picture peg 4 fixed connection is on interior door 2.

The left side of door frame 1 is provided with the drive gear 8 with rotatory handle 14 synchronous rotation, and the vertical rack 9 that meshes with drive gear 8 that is equipped with in drive gear 8's both sides, rack 9 respectively with corresponding montant 5 fixed connection, the equal vertical sliding connection of montant 5 is on door frame 1. Both the upper side and the lower side of the door frame 1 are transversely and slidably connected with a cross rod 6.

Be equipped with rotating member 10 between horizontal pole 6 and the montant 5, rotating member 10 is V type structure, and the articulated connection of rotating member 10 is on door frame 1, and the pin joint of rotating member 10 is located the cross section of horizontal pole 6 and vertical pole extension line, and arc wall 11 is all seted up to the both sides of rotating member 10, and two arc walls 11 are equipped with kelly 12 along the angular bisector symmetry of rotating member 10 in the arc wall 11, kelly 12 is perpendicular to be connected on corresponding montant 5 and horizontal pole 6.

The vertical rods 5 and the cross rods 6 are positioned on the outer sides of the corresponding Contraband type plates 3, the extending directions of the jacks are parallel to the corresponding vertical rods 5 and the corresponding cross rods 6, L-shaped inserting rods 7 are arranged on one sides of the vertical rods 5 and the cross rods 6, and the inner ends of the inserting rods penetrate through the Contraband type plates 3 and are opposite to the jacks.

This device is when using, when needing to lock interior door 2, rotatory handle 14, and the rotation of rotatory handle 14 drives drive gear 8's rotation, because the articulated rack 9 that connects in drive gear 8's both sides, consequently, drive gear 8's rotation drives the rack 9 of both sides and removes towards opposite direction, and then drives corresponding montant 5 and towards opposite reverse movement.

Wherein, the equal fixedly connected with in outer end of montant 5 is located the kelly 12 of arc wall 11, consequently, the removal of montant 5 drives the rotating member 10 and rotates, and wherein, when below montant 5 moves down, the synchronous motion that makes progress of top montant 5 to in two L type inserted bars 7 with montant 5 fixed connection follow montant 5 respectively and remove and insert the jack that corresponds, make inner panel left surface and door frame 1 fixed connection.

And below montant 5 moves down and drives revolving part 10 clockwise (top montant 5 rebound drives revolving part 10 clockwise simultaneously), and then drive horizontal pole 6 that corresponds and move right, the right removal of horizontal pole 6 drives the right removal of L type inserted bar 7, make L type inserted bar 7 insert in the jack, make picture peg 4 and Contraband template 3 fixed connection, and then interior door 2's the side of going up and downside and door frame 1 fixed connection, because interior door 2 opposite side articulates on door frame 1, consequently, interior door 2 all around with door frame 1 fixed connection.

The use of this application can be through rotatory handle 14 for rotatory handle 14 drives drive gear 8 and rotates left side, right side and the upside that realizes door frame 1 and interior door 2 and all fix together, thereby prevents to appear the weak point of spouting the arc, and then prevents that powerful arcing air current will make cabinet door upside or flaw downside impact deformation.

Example 2, as shown in FIGS. 3-4.

Compare in embodiment 1, the difference lies in, steering mechanism includes coaxial fixed connection's last gear 13 and lower gear 15, has all seted up the tooth on the horizontal pole 6, and horizontal pole 6 and the meshing of last gear 13, montant 5 and the meshing of lower gear 15, and below montant 5 is located below lower gear 15 left side, and top montant 5 is located the right side of top lower gear 15, and below horizontal pole 6 all is located the downside that corresponds last gear 13 with top horizontal pole 6.

The downward movement of the lower vertical rod 5 drives the lower gear 15 to rotate anticlockwise, so as to drive the upper gear 13 to rotate anticlockwise, the upper gear 13 rotates anticlockwise to drive the lower cross rod 6 to move rightwards, and similarly, the upward movement of the upper vertical rod 5 drives the upper cross rod 6 to move rightwards synchronously. The L-shaped inserted rod 7 is inserted into the corresponding inserting hole.

The use of this embodiment, compare in embodiment 1, when the montant drove the horizontal pole and removes, the transmission is more silky, makes things convenient for the transmission.

Example 3, as shown in FIGS. 4-5.

Compared with the embodiment 1 and the embodiment 2, the steering mechanism comprises spherical surface bulges 16 fixedly connected to the opposite back ends of the two vertical rods 5, the spherical surface bulges 16 face to the corresponding cross rods 6, one ends of springs 17 are fixedly connected to the L-shaped inserted rods 7 fixedly connected to the cross rods 6, and the other ends of the springs 17 are fixedly connected to the corresponding Contraband type plates 3.

The downward movement of the lower vertical rod 5 (the upward movement of the upper vertical rod 5) drives the protrusion to move, so that the protrusion is close to the corresponding cross rod 6 and extrudes the cross rod 6 to move rightwards, and the L-shaped insertion rod 7 is inserted into the corresponding insertion hole. Wherein, when shifting out L type inserted bar 7 the jack, below montant 5 is to the rebound (top montant 5 is to the rebound), and horizontal pole 6 is kept away from to the arch, because the one end of fixed connection spring 17 on L type inserted bar 7, spring 17 other end fixed connection is on the Contraband template 3 that corresponds, consequently, L type inserted bar 7 promotes L type inserted bar 7 and moves left under the effect of spring 17 for horizontal pole 6 moves left equally.

Compared with the

embodiments

1 and 2, the present embodiment has simpler structure and lower cost.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
