Description

Technical Field

[0001] The utility model relates to the technical field of hinge parts, in particular to a connecting piece of a hinge. Background Art

[0002] In daily life, doors in common household appliances such as doors, windows, cabinets, etc. are installed using door hinges. Hinges are usually formed by riveting or screwing together multiple components such as arm bodies, bases, cup heads, four-hole parts, laminations, etc. There are also tiny parts such as springs, plastic round tubes, U-nails, etc. at the joints of each component. The cup head is a component directly connected to the frame or panel of the door. This connecting piece is one of the components affecting the overall load-bearing of the hinge, and it is rotatably connected to the four-hole part and the lamination.

[0003] In application scenarios such as glass doors, aluminum frame doors or aluminum frame windows, they are generally made of aluminum alloy materials, which are easy to process and can reduce the volume of the connecting piece as a whole. However, due to the relatively low melting point of aluminum alloy, casting process is generally used, and both the process cost and raw material cost are relatively high. Moreover, it is prone to oxidation, has low strength, and overall poor performance.

[0004] Furthermore, for the connecting piece manufactured by the stamping process in the prior art, the stamping and bending sequence is unreasonable, and it cannot fit with the connecting groove of the door, resulting in uneven stress on each bending part and reduced service life. For example, the aluminum frame hydraulic hinge disclosed in the patent number ZL2021203416620 for door and window installation has a housing, a hydraulic cylinder, a hinge arm, a hinge head, and a pin rod. The hinge head, hinge arm, and hydraulic cylinder are sequentially connected and installed on the housing from front to back. The telescopic end of the hydraulic cylinder is connected to the tail end of the hinge arm, and the front end of the hinge arm is connected to the hinge head through a pin rod. The feature is that the hinge head is in a shape of a several-character hollow, and convex ears are provided at both ends of the left and right tops of the hinge head, and holes are provided on the convex ears. The advantages of this utility model are reasonable structural design, strong load-bearing capacity, and better cooperation with connecting components for convenient installation. However, the stamping and bending sequence and the overall structure of this hinge head will cause uneven stress.

[0005] Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Such as Figures 1 to 6As shown in the figure, a connecting piece of a hinge includes a main body 1 and a plurality of through holes provided on the main body 1. The main body 1 includes a top plate 2, a first bending part 3, a second bending part 4 formed by bending both sides of the top plate 2, and a third bending part 5 formed by bending the rear side of the top plate 2. The first bending part 3 has a first extension part 31, a third extension part 32, and a fifth extension part 33 that are bent and connected perpendicularly to each other. The second bending part 4 has a second extension part 41, a fourth extension part 42, and a sixth extension part 43 that are bent and connected perpendicularly to each other. A notch 51 is provided in the middle of the side of the third bending part 5. The main body 1 is made by stamping stainless steel or iron material. It is integrally formed by stamping. The force-bearing points of the connecting piece are dispersed on each extension part, which can reduce the bearing force of the connecting screws and U-shaped nails and is not easy to loosen.

[0029] As Figures 2 to 5 shown in the figure, the first bending part 3 and the second bending part 4 on both sides of the top plate 2 are respectively bent by the first stamping to obtain the first extension part 31 and the second extension part 41. The first extension part 31 and the second extension part 41 are respectively bent and connected at right angles to both sides of the top plate 2 along the Y-axis direction. The first extension part 31 and the second extension part 41 are opposite to each other, and the first extension part 31 and the second extension part 41 are respectively close to both sides of the third bending part 5. First through holes 311 and second through holes 411 are respectively provided on the first extension part 31 and the second extension part 41. The first through holes 311 and the second through holes 411 are communicated and are rotatably connected to a four-hole part 6 through a U-shaped nail. The first bending part 3 and the second bending part 4 respectively have a first protrusion 312 and a second protrusion 412. The first protrusion 312 and the second protrusion 412 are opposite to each other. The first protrusion 312 and the second protrusion 412 respectively have a third through hole 313 and a fourth through hole 413. The third through hole 313 and the fourth through hole 413 are communicated and are rotatably connected to a laminated sheet 7 through a U-shaped nail. The connecting piece is connected to the hinge main body through a U-shaped nail, the first through hole 311, the second through hole 411, the third through hole 313, and the fourth through hole 413. The hinge main body is connected to a fixed surface such as a wall, so that the door body fixed to the connecting piece rotates around the fixed surface. The rear surfaces of the first extension part 31 and the second extension part 41 are in the same plane as the rear surface of the third bending part 5.

[0030] As Figure 4As shown in the figure, the first bending part 3 and the second bending part 4 are respectively obtained by second stamping and bending on the basis of the first extension part 31 and the second extension part 41 to obtain the third extension part 32 and the fourth extension part 42. The third extension part 32 and the fourth extension part 42 are respectively bent and connected at a right angle to the first extension part 31 and the second extension part 41 along the X-axis direction. The first fixing through holes 321 and the second fixing through holes 421 are symmetrically arranged on the third extension part 32 and the fourth extension part 42. Screws respectively pass through the first fixing through holes 321 and the second fixing through holes 421 to fixedly connect the connecting piece with the door body. The third extension part 32 and the fourth extension part 42 are tightly connected to one side of the installation groove of the door body, bearing force on both sides simultaneously, which can disperse the weight pressure of the door body and extend the service life of the connecting piece.

[0031] As Figure 5 shown in the figure, the first bending part 3 and the second bending part 4 are respectively obtained by third stamping and bending on the basis of the third extension part 32 and the fourth extension part 42 to obtain the fifth extension part 33 and the sixth extension part 43. The fifth extension part 33 and the sixth extension part 43 are respectively bent and connected at a right angle to the third extension part 32 and the fourth extension part 42 along the Z-axis direction; the upper surfaces of the fifth extension part 33 and the sixth extension part 43 are respectively parallel to the lower surfaces of the first extension part 31 and the second extension part 41. The fifth extension part 33 and the sixth extension part 43 are attached to the other side of the installation groove of the door body to drive the door body to rotate.

[0032] The main body 1 is formed by stamping stainless steel or iron materials, with a relatively low cost, effectively reducing its production cost, improving market competitiveness, and on the basis of reducing its cost, ensuring the overall strength and durability of the connecting piece, having a strong load-bearing capacity, being able to better cooperate with the four-hole piece 6 and the laminated sheet 7 for installation. The overall stamping structure is easy to process on existing production lines, with a reasonable structural design, reduced scrap rate, and further improved overall competitiveness.
