Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a hinge with good structural strength. Background Art

[0002] Some existing hinges include two single-sided components, which are respectively used to connect to the door frame and the door. The single-sided components are connected to each other through a rotating arm, thereby realizing the opening and closing of the door. For some adjustable hinges, the rotating arm is connected to the adjustment seat, and the position of the adjustment seat is adjustable to achieve the adjustment of the position of the door relative to the door frame. For the above-mentioned hinges, the rotating arms overlap and there is a considerable distance between some rotating arms and the adjustment seat. It is usually necessary to extend a connecting arm from the rotating arm, which extends to the adjustment seat and is rotatably arranged with the adjustment seat. However, since the rotating arm will bear the weight of the door, the connecting arm extended from the rotating arm will bear a large load when the door is repeatedly opened and closed. Moreover, since the rotating arm is generally small in size, the connecting arm is thin. After the hinge is used for a long time, there is a risk of the extending connecting arm from the rotating arm breaking. Utility Model Content

[0041] Reference Figures 1 to 4 A hinge with good structural strength comprises: a base 100, an adjustment base 200, and a rotating arm 300. The adjustment base 200 is disposed on the base 100 and can be adjusted relative to the base 100. One end of the rotating arm 300 is rotatably disposed on the adjustment base 200. The adjustment base 200 comprises a base body 210 and a connecting arm 220. One end of the connecting arm 220 is connected to the base body 210, and the other end of the connecting arm 220 extends toward one end of the rotating arm 300. The base body 210 and the connecting arm 220 are an integrally formed structure, and one end of the rotating arm 300 is rotatably engaged with the connecting arm 220.

[0042] By adopting the above structure, by setting the connecting arm 220 as a part integrally formed with the adjustment seat 200, it is possible to avoid setting the connecting arm 220 on the rotating arm 300, thereby avoiding the problem of low structural strength caused by limiting the size of the connecting arm 220 due to the small rotating arm 300. Moreover, by setting the connecting arm 220 on the adjustment seat 200, there is more space, which makes it convenient to thicken the connecting arm 220 or add a reinforcement structure, thereby making the structural strength of the hinge better.

[0043] In this embodiment, the connecting arms 220 are arranged in pairs and are located on either side of one end of the rotating arm 300. The two connecting arms 220 clamp one end of the rotating arm 300, and the two sides of one end of the rotating arm 300 respectively rotate coaxially with the two connecting arms 220. With this structure, the rotating arm 300 is rotatably connected to the two connecting arms 220 on both sides, thereby ensuring stable operation and a solid structure. It is conceivable that in some embodiments, the rotating arm 300 can also be rotatably connected to the connecting arm 220 on one side, and the specific configuration can be based on actual circumstances.

[0044] In the embodiment, a pivot 230 is connected between the two connecting arms 220, and one end of the rotating arm 300 is rotatably connected to the pivot 230. By providing the above-mentioned pivot 230, the rotation connection of the rotating arm 300 can be facilitated, and the pivot 230 connects the two rotating arms 300 together, and the structural strength is good.

[0045] In this embodiment, the connecting arm 220 is provided with a first mounting hole 221. The first mounting holes 221 of the two connecting arms 220 are coaxially arranged. The first mounting holes 221 are through-holes. The pivot 230 is inserted through the two first mounting holes 221. One end of the pivot 230 is provided with a flange end, and the other end of the pivot 230 is provided with a riveted portion. The flange end and the riveted portion clamp the adjustment seat 200. With this structure, the pivot 230 is firmly fixed, and the use of riveted fixation can also save fasteners.

[0046] In the embodiment, the rotating arm 300 is provided with a second mounting hole 310, in which a sleeve 320 is mounted. The sleeve 320 is adapted to fit the pivot 230, and the pivot 230 is passed through the sleeve 320. The rotating arm 300 fits smoothly and well with the pivot 230 through the sleeve 320.

[0047] In this embodiment, the sleeve 320 includes an insert portion 321 and a flange portion 322. The flange portion 322 is disposed at one end of the insert portion 321. The insert portion 321 is adapted to and inserted into the second mounting hole 310. The pivot 230 is disposed through the insert portion 321. The flange portion 322 is disposed between the end surface of the other end of the connecting arm 220 and the end surface of the rotating arm 300. With this structure, the insert portion 321 can withstand radial forces, while the flange portion 322 can withstand axial forces, thereby ensuring smoother engagement of the rotating arm 300 with the connecting arm 220 in both directions.

[0048] In the embodiment, the end surface of the rotating arm 300 corresponding to the other end of the connecting arm 220 is a flat end surface. By forming the connecting arm 220 integrally with the adjustment base 200, the end surface of the rotating arm 300 can be set to a flat end surface, thereby making the structure of the rotating arm 300 regular and easy to manufacture.

[0049] In the embodiment, one side surface of the connecting arm 220 is coplanar with one side surface of the seat body 210 , thereby achieving good structural strength and a regular structure.

[0050] In an embodiment, a reinforcing rib is provided between the connecting arm 220 and the seat body 210 , so that the strength of the connecting arm 220 can be enhanced by the reinforcing rib.

When the second adjustment screw 600 is rotated, the position of the adjustment base 200 relative to the base 100 can be adjusted, thereby adjusting the left and right position of the door. The adjustment base 200 of the other single-sided assembly is divided into two parts: a vertical adjustment base 240 and a front-to-back adjustment base 250. The vertical adjustment base 240 defines a second vertical adjustment bar hole 241, which is penetrated by a second bar screw 710. The second bar screw 710 passes through the base 100 and is secured with a second nut 720. The front-to-back adjustment base 250 is overlapped on the vertical adjustment base 240. The front-to-back adjustment base 250 defines a third horizontal adjustment bar hole 251, which is penetrated by a third bar screw 730. The third bar screw 730 passes through the vertical adjustment base 240 and is secured with a third nut 740. The pivot arm 300 is connected to the front-to-back adjustment base 250. By means of the adjustment strip holes extending vertically and horizontally and the corresponding threaded fasteners, the vertical position adjustment of the adjustment seat 200 as a whole relative to the base 100 and the front and rear adjustment of the front and rear adjustment seat 250 relative to the upper and lower adjustment seat 240 can be achieved, thereby achieving the adjustment of the door relative to the door frame in the vertical and front and rear directions. The surfaces that cooperate with each other between the upper and lower adjustment seat 240 and the front and rear adjustment seat 250, and the surfaces that cooperate with each other between the upper and lower adjustment seat 240 and the base 100 are both provided with tooth surface patterns, and the teeth of the tooth surfaces that cooperate with each other between the upper and lower adjustment seat 240 and the front and rear adjustment seat 250 can enhance the stability of the cooperation. The teeth of the tooth surfaces that cooperate with each other between the upper and lower adjustment seat 240 and the front and rear adjustment seat 250 extend vertically; the teeth of the tooth surfaces that cooperate with each other between the upper and lower adjustment seat 240 and the base 100 extend horizontally.

[0053] exist Figures 8 to 10In this embodiment, the base 100, adjustment base 200, and pivot arm 300 are provided in two groups, forming two single-sided assemblies for connection to the door frame and door, respectively.
