DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] See also Figure 1 and 2 As shown, the present invention is a refrigerator hinge with adjustable spacing, comprising a hinge body 1; a screw straight slot 101 is provided on the vertical side wall of the hinge body 1, a screw is inserted into the screw straight slot 101, and the position is adjusted in the screw straight slot 101 to correspond to the position of the threaded hole on the refrigerator body, so that the hinge can adapt to the threaded holes at different positions on the refrigerator body. A hinge shaft straight slot 104 is provided on the horizontal side wall of the hinge body 1, and similarly, the hinge shaft can be adjusted in the hinge shaft straight slot 104.

[0030] The inner bottom surface and the inner top surface of the screw straight slot 101 are both provided with a slide slot 102; the inner bottom surface and the inner top surface of the screw straight slot 101 are evenly provided with limit slots 103 along the length direction of the slide slot 102; the limit slots 103 are connected to the slide slot 102. The screw straight slot 101 and the hinge shaft straight slot 104 have the same internal structure, and both are connected with a positioning device 2.

[0031] like Figure 3-6As shown, the positioning device 2 includes a fixed block 201; a sliding block 202 that cooperates with the slide slot 102 is fixedly connected to the opposite outer wall of the fixed block 201, and the sliding block 202 is inserted into the slide slot 102, so that the positioning device 2 as a whole can move along the screw straight slot 101 and the hinge shaft straight slot 104. A rectangular blind hole 203 is opened on the side of the fixed block 201; a screw through hole 204 is opened on the inner side of the rectangular blind hole 203; and a pressing block 3 is adapted to be installed in the rectangular blind hole 203.

[0032] Rectangular grooves are formed on opposite side walls of the fixing block 201 ; a positioning strip 205 is fixedly connected in the rectangular groove; the width of the positioning strip 205 is less than or equal to the width of the limiting slot 103 ; the upper end of the positioning strip 205 is located on one side of the rectangular blind hole 203 and a wedge block 206 is fixedly connected thereto.

[0033] A through hole 301 is provided on the side of the clamping block 3, which is concentric with the screw through hole 204; a clamping slot 302 corresponding to the positioning strip 205 is provided on the side wall of the clamping block 3; the wedge block 206 is loosely matched with the clamping slot 302; and the side of the clamping slot 302 away from one end of the wedge block 206 is a slope structure.

[0034] The screw passes through the through hole 301 and the screw through hole 204 in sequence, the positioning device 2 is located in the screw straight slot 101, and the side of the clamping block 3 extends out of the screw straight slot 101. When the screw is connected with the threaded hole of the refrigerator body, the screw head squeezes the clamping block 3 and presses the clamping block 3 into the rectangular blind hole 203.

[0035] When the pressing block 3 moves toward the rectangular blind hole 203, the positioning strip 205 is pushed toward the outside of the fixing block 201 through the inclined surface of the clamping notch 302, so that the positioning strip 205 is squeezed into the limiting clamping slot 103, so that the position of the fixing block 201 relative to the screw straight notch 101 is fixed, so as to achieve a better fixing effect. The hinge shaft is also fixed in the hinge shaft straight notch 104 through the positioning device 2.

[0036] Preferably, the cross-section of the limiting card slot 103 is rectangular or arc-shaped. The positioning bar 205 is adapted to the shape of the inner wall of the limiting card slot 103. The rectangular shape makes the limiting effect of the positioning bar 205 and the limiting card slot 103 better, while the arc-shaped structure makes it easier for the positioning bar 205 to be inserted into the limiting card slot 103.

[0037] At the same time, the side of the sliding block 202 away from the fixed block 201 is arc-shaped. The inner wall of the slide slot 102 is adapted to the fixed block 201, and the arc surface structure makes the inner wall of the slide slot 102 and the fixed block 201 fit better, making the movement of the fixed block 201 more stable, which is conducive to improving the overall stability.
