As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

Figure 6 A schematic diagram showing the assembly of a door cabinet using a jig according to an embodiment of the present application is shown. Figure 7 The figure shows the installation completion diagram of the door cabinet assembly using the fixture of one embodiment of the present application. Figures 1 to 7 As shown, the jig 400 is used to assemble with the door hinge 300. The door hinge 300 (such as a cup-shaped concealed hinge) includes a first end (hinge cup) 310 and a second end (hinge arm) 320. The first end 310 is used to be fixed on the door panel 200, and the second end 320 is used to be fixed on the side panel 100. The second end 320 includes a base 321, and the base 321 is provided with a threaded hole 322 for fixed connection with the side panel 100; the door hinge 300 is used to realize the opening and closing of the door panel 200 and the side panel 100; the jig 400 includes: a cover body 410 and a plurality of limit blocks 420.

[0032] The cover body 410 is covered on the base 321 to realize the assembly and fixation of the fixture 400 and the base 321. The cover body 410 and the base 321 can be detachably installed. The cover body 410 is covered on the base 321, and can be a partial area covered on the base 321, which does not represent full coverage. The position of the partial area covered is determined according to the position of the threaded hole 322. A through hole 411 is provided on the cover body 410; the through hole 411 passes through the cover body 410, so that the screw 500 can pass through the through hole 411 and be fixedly connected to the threaded hole 322 on the base 321.

[0033] The fixture 400 also includes a plurality of limit blocks 420. The plurality of limit blocks 420 are fixedly connected to the side walls of the through-hole 411 by connecting rods 430, respectively, to form limit holes 421. It can be understood that the inner side walls of the plurality of limit blocks 420 are arc-shaped, so that when the outer side walls of the plurality of limit blocks 420 are fixedly connected to the side walls of the through-hole 411 by connecting rods 430, the inner side walls of the plurality of limit blocks 420 form the shape of the limit holes 421. The plurality of limit blocks 420 can be arranged at intervals, so that the limit holes 421 of the embodiment of the present application are not closed holes, and can be used as a hole to implement the function of limiting when the screw 500 is assembled. The limit hole 421 is coaxial with the threaded hole 322 and the inner diameter of the limit hole 421 is adapted to the inner diameter of the threaded hole 322. When the screw 500 is assembled, the tooth portion 510 of the screw 500 can pass through the limiting hole 421 and fit the side wall of the limiting hole 421, limiting the screw 500 to a square coaxial with the threaded hole 322, making it convenient to assemble the screw 500 into the threaded hole 322 according to a preset angle.

[0034] In the embodiment of the present application, the limiting hole 421 may also be a polygonal non-closed hole that can fit with the thread portion 510 of the screw 500 to implement the limiting function.

[0035] The jig 400 provided in the embodiment of the present application is covered on the base 321. When assembling the door cabinet, first fix the first end 310 of the door hinge 300 on the door panel 200, then hold the door panel 200 with one hand to align it with the side panel 100, and use the other hand to turn the screw 500 through the tightening tool 600 to fix the second end 320 of the door hinge 300 to the side panel 100, so that one person can complete the assembly. After the assembly is completed, the jig 400 can be removed to avoid affecting the appearance of the door cabinet after installation. The door cabinet after installation looks like this Figure 7 shown.

[0036] In one embodiment, the cover 410 includes at least two side surfaces 412, which are engaged with the base 321. The at least two side surfaces 412 can be opposite sides, clamping from opposite sides of the base 321 to secure the cover 410 to the base 321. The at least two side surfaces 412 can be engaged with the base 321 by providing snaps and buckles on the side surfaces 412 and the base 321, respectively. Alternatively, the snaps or buckles may be omitted, and the cover 410 can be secured to the base 321 directly by the tension of the two side surfaces 412.

[0037] In one example, the cover 410 includes three side surfaces 412, which are snap-fitted to the base 321. Considering that the threaded hole 322 is typically located at the rear end of the base 321, that is, typically positioned close to the edge, two of the side surfaces 412 of the cover 410 are positioned opposite each other, covering both sides of the base 321; the other side surface 412 snap-fits to the side of the base 321 near the threaded hole 322. Thus, the cover 410 can be securely mounted on the base 321 by snapping the three side surfaces 412 together, ensuring that the cover 410 is securely mounted without affecting the functionality of the base 321.

[0038] The cover body 410 in the embodiment of the present application includes at least two side surfaces 412, which may be two side surfaces 412, three side surfaces 412 or multiple side surfaces 412; in the case of multiple side surfaces 412, it can be understood that the partial area covered on the base 321 is multi-deformable, and the structure of the cover body 410 is adapted to the covering area.

[0039] The cover 410 in the embodiment of the present application covers a partial area on the base 321 . It can be understood that at least one side surface 412 of the cover 410 is an opening.

[0040] In one embodiment, at least one side surface 412 of the cover 410 is provided with a U-shaped recess 413 , and the opening of the U-shaped recess 413 faces the base 321 .

[0041] In the embodiment of the present application, a U-shaped recess 413 is provided on at least one side surface 412 of the cover body 410, so that when the door cabinet is assembled, the jig 400 can be pried open through the position of the U-shaped recess 413, thereby facilitating the removal of the jig 400 and avoiding affecting the appearance of the door cabinet after installation.

[0042] In one embodiment, the fixture 400 further includes a positioning post 440 , which is fixed to the cover 410 ; the base 321 includes a positioning hole 323 , and when the cover 410 is covered on the base 321 , the positioning post 440 is inserted into the positioning hole 323 .

[0043] The positioning post 440 can be integrally formed with the cover 410. The shape of the positioning post 440 matches the position and shape of the positioning hole 323 on the base 321, allowing the positioning post 440 to be inserted into the positioning hole 323. The positioning hole 323 provided on the base 321 is located adjacent to the threaded hole 322. The radius of the through-hole 411 on the cover 410 is smaller than the distance from the threaded hole 322 to the positioning hole 323, allowing the positioning post 440 to be located adjacent to the through-hole 411. The positioning post 440 is located adjacent to the side of the opening of the cover 410.

[0044] In one embodiment, one limiting block 420 corresponds to two connecting rods 430 , and the two connecting rods 430 extend from both ends of the limiting block 420 to the side walls of the through hole 411 .

[0045] In the embodiment of the present application, the two ends of the limiting block 420 refer to the two ends along the circumferential direction of the through hole 411.

[0046] In the embodiment of the present application, a stopper 420 is connected to two connecting rods 430, so that when the screw 500 is tightened, the stopper 420 is squeezed by the head 520 of the screw 500, and there is still elastic space to squeeze outward. When the stopper hole 421 is in contact with the thread portion 510 of the screw 500, the screw 500 can still be tightened. The stopper 420 squeezes outward without hindering the movement of the head 520 of the screw 500. After the screw 500 is tightened, the stopper 420 can rebound.

[0047] In one embodiment, the limit block 420 includes an inner arc surface 422 and an outer arc surface 423; the bottom of the inner arc surface 422 is flush with the bottom of the outer arc surface 423; the top of the outer arc surface 423 is set higher than the top of the inner arc surface 422; the top of the outer arc surface 423 smoothly transitions to the top of the inner arc surface 422, forming the upper side surface 412 of the limit block 420.

[0048] The inner arc surfaces 422 of the plurality of limiting blocks 420 form limiting holes 421. The bottoms of the inner arc surfaces 422 and the outer arc surfaces 423 can be flush with the bottom of the through hole 411.

[0049] The top of the outer curved surface 423 and the top of the inner curved surface 422 are both higher than the cover 410. The height of the inner curved surface 422 matches the height of the teeth 510 of the screw 500. The height of the outer curved surface 423 above the inner curved surface 422 can match the height of the head 520 of the screw 500. The top of the outer curved surface 423 smoothly transitions to the top of the inner curved surface 422, forming the upper side surface 412 of the limit block 420. The upper side surface 412 of the limit block 420 matches the head 520 of the screw 500, allowing the head 520 of the screw 500 to fit against the upper side surface 412 of the limit block 420. When the fixture 400 is used to limit the screw 500, the upper side surface 412 of the limit block 420 can limit the head 520 of the screw 500, further improving the accuracy of the limit and making the process of tightening the screw 500 more precise and smooth.

[0050] In one example, when the fixture 400 is covered on the base 321, the bottom of the through hole 411 of the cover body 410 is close to the threaded hole 322, and the limit block 420 abuts against the top of the threaded hole 322; the height of the inner arc surface 422 of the limit block 420 is the same as the height of the tooth portion 510 of the screw 500, the screw 500 passes through the limit hole 421, the introduction portion enters the threaded hole 322, and the head 520 fits against the upper side surface 412 of the limit block 420, which can hold the screw 500 very stably and facilitate the tightening of the screw 500.

[0051] In one embodiment, the curvature of the outer arc surface 423 is smaller than that of the inner arc surface 422 ; the side arc of the outer arc surface 423 transitions to the side of the inner arc surface 422 .

[0052] The inner arc surfaces 422 of the plurality of limit blocks 420 are spaced apart by a distance, but for better positioning, the spacing distance is smaller, smaller than the spacing distance of the outer arc surfaces 423. Therefore, the curvature of the outer arc surface 423 is smaller than that of the inner arc surface 422.

[0053] The side arc of the outer arc surface 423 transitions to the side of the inner arc surface 422 , which can be a curved arc transition.

[0054] Between two adjacent limit blocks 420, the spacing distance of the outer arc surface 423 is greater than the spacing distance of the inner arc surface 422, which can provide the limit blocks 420 with more space for extrusion outward, making it easier for the limit blocks 420 to be extruded outward when the screws 500 are tightened.

[0055] In one embodiment, there are three limit blocks 420 , and the three limit blocks 420 have the same shape. The curvature of the inner arc surface 422 of the limit block 420 is 100°-115°.

[0056] The three stoppers 420 provide a secure position while facilitating the machining of the jig 400. The inner arc surface 422 of each stopper 420 has an angle of less than 120°, ensuring a spacing between adjacent stoppers 420. The arc of the inner arc surface 422 is between 100° and 115°, ensuring that the stopper holes 421 formed by the three stoppers 420 securely hold the screws 500 in place.

[0057] In one embodiment, the fixture 400 is a plastic part; the cover 410 and the limiting block 420 are integrally formed.

[0058] The fixture 400 in the embodiment of the present application is a disposable component, which is provided to facilitate the assembly of the door cabinet and does not need to have long-term stability. Therefore, it is made of plastic material and has a certain elasticity to facilitate the screw 500 to pass through the limit block 420 and be tightened toward the threaded hole 322.

[0059] The cover 410 and the limit block 420 are integrally formed, which can facilitate the processing of the jig 400. At the same time, a stable connection is maintained between the limit block 420 and the cover 410 to avoid breakage between the limit block 420 and the cover 410 when the jig 400 has not been assembled.

[0060] On the other hand, the cover 410 and the limit block 420 are integrally formed, so that a narrower connecting rod 430 can be set to connect the cover 410 and the limit block 420, so that the connecting rod 430 has both toughness and elasticity, further facilitating the assembly of the door cabinet.

[0061] Other components of the fixture 400 of the above embodiment may adopt various technical solutions known to ordinary technicians in this field now and in the future, and will not be described in detail here.

[0062] The present application also provides a door hinge comprising a door hinge body and a jig according to any of the aforementioned embodiments, with the jig cover disposed on the base of the door hinge body.

The jig is used to assist in securing the door hinge body to the door panel and side panels during cabinet door installation.

[0063] The embodiment of the present application adopts the above-mentioned technical solution by installing a jig cover on the base.

When assembling the cabinet door, one person can hold the door panel with one hand and turn the screws with the other, completing the assembly by themselves.
