DETAILED DESCRIPTION

[0031] The following will be combined with the Figures 1-4 The application will be further described in detail.

[0032] The application discloses a novel hinge frame for door panel hinging.

[0033] Referring to Figure 1 A novel hinge frame for door panel hinging, comprising a door panel hinge 1, a door frame hinge 2 and a rotating shaft 3 for realizing the hinge structure and respectively hinged to the mutually close sides of the door panel hinge 1 and the door frame hinge 2. The sliding seat one 11 is fixedly installed on the middle part of the door panel hinge 1 along the vertical direction, and the sliding seat two 21 is fixedly installed on the middle part of the door frame hinge 2 along the vertical direction and located on the same horizontal plane as the sliding seat one 11. The sliding groove one 111 and the sliding groove two 211 are respectively arranged on the sliding seat one 11 and the sliding seat two 21 along the length direction and located on the same horizontal plane.

[0034] Referring to Figure 1 And Figure 2 Specifically, the sliding groove one 111 and the sliding groove two 211 are both T-shaped clamping grooves, and the two ends of the connecting rod 4 are respectively slidably arranged in the sliding groove one 111 and the sliding groove two 211. The connecting rod 4 is used for connecting the door panel hinge 1 and the door frame hinge 2 and limiting the hinge angle between the two. The two ends of the connecting rod 4 are symmetrically and integrally connected with the blocking columns 41, which are used for forming a sliding clamping structure with the sliding groove one 111 and the sliding groove two 211 to avoid the connecting rod 4 from easily coming out.

[0035] The abutting block 2111 is also slidably arranged in the second sliding groove 211, and abuts against the connecting rod 4 and is connected with the adjusting device 5. When it is needed to change the hinged angle of the door plate, the abutting block 2111 can be driven to move by the adjusting device 5, and then the position of the end of the connecting rod 4 in the second sliding groove 211 is changed, and the operation is labor-saving and the structure is simple.

[0036] Preferably, the connecting rod 4 is in an arc structure, and the inner side of the connecting rod 4 is close to the rotating shaft 3, so that the door plate can be completely opened to 90 degrees when rotating, and the passing is facilitated. Meanwhile, the connecting rod 4 also has bending elasticity, and when the door plate is suddenly forced after being rotated to a certain angle and being locked, the connecting rod 4 can automatically reset. This structure not only has a buffering effect on the door plate, but also can prevent the connecting rod 4 from being damaged.

[0037] Preferably, the four blocking columns 41 are each rotationally sleeved with a bearing bush 411, and the bearing bush 411 abuts against the inner side wall of the first sliding groove 111 and the second sliding groove 211, so as to change the sliding of the blocking column 41 into the rolling of the bearing bush 411, and the opening process of the door plate is more smooth and convenient, the influence of rust is eliminated, and the wear of parts is reduced.

[0038] Referring to Figure 2 and Figure 3 , specifically, the adjusting device 5 includes a positioning seat 51 which is vertically connected to the door frame hinge 2 at the end of the sliding seat 21 away from the rotating shaft 3, and an adjusting rod 52 which is vertically slidably arranged in the top side of the positioning seat 51. The positioning seat 51 is provided with a positioning groove 511 which is open along the length direction and is in communication with the second sliding groove 211, and the positioning groove 511 is rotationally installed with an adjusting gear 53 at the middle position. The length direction of the adjusting rod 52 is provided with a rack 521 which is in mesh with the adjusting gear 53, and when the adjusting rod 52 slides in the positioning seat 51, the adjusting gear 53 can be driven to rotate through the mesh transmission.

[0039] The tooth surface of the adjusting gear 53 is hingedly connected with a push rod 54 which is hingedly connected with the abutting block 2111, and when the adjusting gear 53 rotates, the push rod 54 drives the abutting block 2111 to slide in the second sliding groove 211, so as to control the position of the end of the connecting rod 4 in the second sliding groove 211. This structure has a self-locking ability, and when the door plate is accidentally touched, this structure can avoid the door plate from being quickly closed, so as to leave time for the reaction of people and increase the safety.

[0040] Referring to Figure 3Further, a plurality of connecting screw holes 531 are equidistantly arranged on the tooth surface of the adjusting gear 53 in the circumferential direction, and the distance between the plurality of connecting screw holes 531 and the axis of the adjusting gear 53 increases equidistantly in the radial direction. A connecting stud 55 is arranged on the end of the push rod 54 away from the abutting block 2111, and the lower end of the connecting stud 55 penetrates through the push rod 54 and is screwed into one of the connecting screw holes 531.

[0041] When the connecting stud 55 is arranged in the connecting screw holes 531 at different radial positions, the abutting block 2111 slides in the sliding groove two 211 by a different distance range for each rotation of the adjusting gear 53. For the case of needing to rotate or lock the door plate at an angle between 0-90°, the operation of this structure is more flexible to adapt to the different needs of the operator.

[0042] Referring to Figure 4 Further, the adjusting rod 52 is in close contact with the inner side wall of the positioning groove 511 on the side away from the adjusting gear 53. Further, a plurality of telescopic buckles 522 are arranged on the adjusting rod 52 in the length direction. The plurality of telescopic buckles 522 are all hemispherical structures, and a compression spring 523 is connected between the planar side of the telescopic buckle 522 and the adjusting rod 52, and the telescopic buckle 522 can be completely retracted into the adjusting rod 52. A plurality of clamping holes 512 matched in size with the telescopic buckles 522 are equidistantly arranged on the side wall of the positioning seat 51.

[0043] When the end of the connecting rod 4 moves to a certain position in the sliding groove two 211, part or all of the plurality of telescopic buckles 522 on the adjusting rod 52 enter the plurality of clamping holes 512 respectively, so as to limit the adjusting rod 52, which is simple to operate and not prone to failure.

[0044] Referring to Figure 3 and Figure 4 In order to make the operation of the door plate more convenient when rotating and locking, the positioning seat 51 is slidably arranged with a reset rod 56 on the end away from the adjusting rod 52 in the length direction. The reset rod 56 also slides through the positioning groove 511 and is in abutment with the adjusting rod 52. When the adjusting rod 52 moves downward, the reset rod 56 also moves downward and extends out of the positioning groove 511. At this time, pressing the reset rod 56 can reset the adjusting rod 52, thereby releasing the locking of the door hinge 1 and the door plate.

[0045] Referring to Figure 1 and Figure 4 The door hinge 1 is also integrally connected with an anti-collision strip 6 near the door frame hinge 2 to avoid collision between the door hinge 1 and the door frame hinge 2, so as to avoid damage caused by collision between the door hinge 1 and the door frame hinge 2 when the door is closed too hard, thereby playing a protection role and a mute effect, and also providing a buffer.

[0046] The implementation principle of the novel hinge frame for hinging the door panel is as follows:

[0047] The adjusting lever 52 is moved by pressing, and the adjusting gear 53 is driven to rotate. At this time, the end of the push rod 54 is hinged to the tooth surface of the adjusting gear 53 through the connecting stud 55, so that when the adjusting gear 53 rotates, the abutting block 2111 connected with the push rod 54 is driven to slide in the sliding groove two 211. At this time, since the moving space of the connecting rod 4 in the sliding groove two 211 is reduced, the door panel hinge 1 and the certain angle position of the door panel lock can be locked.

[0048] When it is needed to lock the door panel at different hinge angle positions, it is only needed to insert the connecting stud 55 into the adjusting screw hole at different positions on the adjusting gear 53, and then adjust, and the structure is to meet the operation requirement of some door panels which do not need to be opened.

[0049] When it is needed to close the door panel, the reset rod 56 below the positioning seat 51 is pushed up to reset the adjusting lever 52, and drive the abutting block 2111 to move, at this time, the end of the connecting rod 4 has a larger moving space in the sliding groove two 211, and the door panel can be rotated in a larger angle range.

[0050] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
