Description

The mechanical type cabinet supports

Technical field

The utility model belongs to a kind of Cabinet hinge, especially a kind of Cabinet hinge that has freewheel clutch.

Background technology

Cabinet hinge structure commonly used generally is to adopt lever arm by ratchet and the engagement of ratchet circle arm ratchet, and its lever arm, ratchet circle arm cover hinged with cabinet, cabinet respectively.The ratchet circle of its ratchet circle arm is provided with crossette and matches with lever arm cell, annular groove; The crossette back side of its ratchet circle is provided with groove and cooperates with the crossette of ring washer, and ring washer is arranged in the annular groove of lid, and lid is provided with prominent drum, and prominent drum is provided with the groove fit of at least one reversed column and lever arm, and its lid is spirally connected by sunk screw and lever arm.Be provided with packing ring between its ratchet circle arm and the lever arm, the packing ring bead cooperates with lever arm annular groove outer rim, packing ring is provided with groove and cooperates with the crossette of ratchet circle; Be provided with egative film between its lid and the ratchet, circle is provided with at least one convex shoulder and the groove fit of covering on the prominent drum in the egative film, is provided with at least one pad between lid and the sunk screw.The day for announcing is the disclosed pawl type supporting hinges that comes to this of the patent CN2563263 of 2007.07.30, and the processing and manufacturing of this pawl type supporting hinges is difficulty relatively, and bearing capacity is less, and the random anglec of rotation, and installation process is difficulty relatively, the influence use.

The utility model content

The purpose of this utility model is to solve the aforesaid drawbacks, and makes handling ease, and bearing capacity is big, and any anglec of rotation of energy, and installation process is convenient and simple, is convenient to promote.

The utility model comprises first swing arm, second swing arm, cover plate, dormant bolt, back-up ring, spring leaf, it is characterized in that being provided with freewheel clutch between first swing arm and second swing arm, and freewheel clutch comprises cavity, fluted disc and the roller of annular; The cavity and second swing arm are affixed, the fluted disc kink is outside the central axis of cover plate, cavity surrounds fluted disc, roller is placed in the tooth paddy place of fluted disc, a side tooth root of each tooth is to the distance of the cavity inner wall diameter greater than roller on the fluted disc, and the opposite side tooth root of each tooth is to the distance of the cavity inner wall diameter less than roller on the fluted disc; Dormant bolt passes in the screw that spring leaf, cover plate, back-up ring, fluted disc and back-up ring screw in first swing arm; The free end of first swing arm is hinged to flat sign indicating number by junction button, and the free end of second swing arm is hinged to the angle sign indicating number by junction button.

Suppose that first swing arm is fixed on the cabinet wall, second swing arm is installed on the cabinet door; When external force made second swing arm turn to first swing arm in a clockwise direction, freewheel clutch was in released state, and the cabinet door is easy to turn to cabinet; When external force makes second swing arm turn to first swing arm with counter clockwise direction, freewheel clutch is in bonding state, the cabinet door can not leave the cabinet wall according to reason, because the fluted disc of freewheel clutch is connected with friction mode with second swing arm, as long as the external force that the cabinet door is applied greater than this frictional force just can make the cabinet door open.First swing arm and second swing arm are hinged with flat sign indicating number or angle sign indicating number by resilient plastics junction button respectively, and flat sign indicating number and angle sign indicating number can be installed and removed and exchange easily.

The support of this cabinet has handling ease, bearing capacity is big and the good result of any anglec of rotation of energy, and mounts and dismounts convenient and simple.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the outside drawing of embodiment;

Fig. 3 is the schematic diagram that freewheel clutch is in released state;

Fig. 4 is the schematic diagram that freewheel clutch is in bonding state.

The specific embodiment

Referring to Fig. 1～Fig. 2, embodiment comprises that first swing arm 1, second swing arm 2, cover plate 3, dormant bolt 4, back-up ring 5, spring leaf 6, the first swing arms 1 one ends extend into disk 12, and disk 12 centers are shaped on screw 11.Be provided with freewheel clutch between first swing arm 1 and second swing arm 2, freewheel clutch is made up of cavity 7, fluted disc 8 and the roller 9 of annular; One end of the cavity 7 and second swing arm 2 is affixed, and fluted disc 8 has 6 teeth, and there is through hole 13 at fluted disc 8 centers, and fluted disc 8 kinks are outside the central axis 10 of cover plate 3 bottoms and can center on central axis 10 rotations; The external diameter of fluted disc 8 is less than the internal diameter of cavity 7, cavity 7 surrounds fluted disc 8, there are 6 rollers 9 to be placed in the tooth paddy place of fluted disc 8, the left side tooth root of each tooth is to the distance of the cavity 7 inwalls diameter greater than roller 9 on the fluted disc 8, the right side tooth root of each tooth is to the distance of the cavity 7 inwalls diameter less than roller 9 on the fluted disc 8, makes that the line between the tooth root of adjacent two teeth is one section ramped shaped line.In the top and bottom of fluted disc 8 back-up ring 5 is arranged respectively, dormant bolt 4 passes 11 li of the screws that 3 spring leafs 6, cover plate 3, back-up ring 5, fluted disc 8 and back-up ring 5 are tightened on the disk 12 of first swing arm 1 successively, makes the disk 12 of the cover plate 3 and first swing arm 1 clamp the fluted disc 8 of freewheel clutch from upper and lower surface.

As shown in Figure 3, imagination fluted disc 8 is fixedly the time, if clockwise rotate second swing arm 2,6 rollers 9 are driven the left side of each tooth of deflection by cavity 7 inwalls, because the left side tooth root of each tooth is to the distance of the cavity 7 inwalls diameter greater than roller 9, so roller 9 does not contact with cavity 7 with fluted disc 8 simultaneously, the separated attitude of freewheel clutch, the rotation of second swing arm 2 is not obstructed.

As shown in Figure 4, when if inhour is rotated second swing arm 2,6 rollers 9 are pressed to the right side of each tooth by cavity 7, because the right side tooth root of each tooth is to the distance of the cavity 7 inwalls diameter less than roller 9, so roller 9 blocks fluted disc 8 and cavity 7 simultaneously, freewheel clutch is bonding state, second swing arm 2 that driven by external force drives fluted disc 8 and rotates synchronously, fluted disc 8 and two back-up rings 5 overcome spring leaf 6 its frictional force that applies are slided between the disk 12 of the cover plate 3 and first swing arm 1, i.e. second swing arm 2 is rotated under the state of being obstructed.

Angle sign indicating number 15 peace sign indicating number 16 respectively riveting that the free end of plastic junction button 14, the first swing arms 1 and second swing arm 2 is housed is hinged with angle sign indicating number 15 peace sign indicating numbers 16 by junction button 14 correspondences; Button bar is arranged on the junction button, first swing arm 1 or second swing arm 2 are separated with junction button 14, thereby the installation and removal that cabinet is supported become very simple as long as pull open button bar.

In addition, there is a projection 17 cavity 7 lower ends of present embodiment second swing arm 2, projection 17 can slide along the circular groove on the disk 12 of first swing arm 1 18, locating slot 19 is arranged on the circular groove 18, locating slot is equipped with direction position-sensing switch 20 for 19 li, direction position-sensing switch 20 is setovered by a back-moving spring 21 and circular groove 18 is blocked, thereby the mutual scope of activities of two swing arms is divided into the zone of two 180 degree, pull open direction position-sensing switch 20 and can make projection 17 select to enter zones of different, to adapt to the opposite mounting means of left and right sides cupboard door.
