Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to an easy-to-install hardware hinge. Background Art

[0002] A hinge generally includes a hinge cup fixed to a door panel, a hinge seat assembly fixed to a cabinet frame, and a transmission assembly that enables the hinge cup to open and close on the hinge seat assembly.

[0003] The current hinge connection method between the hinge seat assembly and the cabinet frame is screw fixing, and there is a mounting hole for the screw to pass through on the hinge seat. However, the base part of the current hinge seat mostly has two round holes that cooperate with the screws for fixing. This hole opening method cannot adjust the horizontality of the base again after the screws are fixed. After the current hinge is installed, the hinge arm and the base need to be adjusted with the built-in eccentric screw to adjust the height of the door panel. Therefore, it is difficult to install it to a horizontal state in one go. The requirements for the installation master are very high, resulting in great difficulty in installation. Although the eccentric screw can adjust the height, it cannot adjust the horizontality. Due to the existence of the eccentric screw, a lateral sliding structure needs to be separately set inside the base to adjust the height of the hinge arm relative to the base, resulting in a more complicated structure. Therefore, most of the existing hinge bases are three-layer structures, which are difficult and costly to manufacture. They are easy to loosen after long-term use. In addition, the traditional hinge arm will block the mounting hole, and it is difficult for the screw-tightening tool to reach into the base to turn the screw. The installation of two screws will easily loosen after long-term use. Utility Model Content

[0004] In order to solve the shortcomings of the prior art such as high difficulty in horizontal installation and easy loosening after long-term use, the utility model provides an easy-to-install hardware hinge.

[0005] The technical solution of the utility model is:

[0006] The utility model provides an easy-to-install hardware hinge, comprising a base, a hinge arm arranged on the upper part of the base, one end of the hinge arm being hinged to the hinge cup through a connecting rod assembly, a plurality of groups of mounting holes being provided at the bottom of the base, each group of mounting holes comprising at least one long hole and one positioning hole, the hinge arm being connected to the base through an adjusting screw, and a first yielding window being provided at a position of the hinge arm corresponding to the mounting hole.

[0007] Furthermore, the base includes a lower base and an upper base, and the upper base and the lower base are fixedly connected via a connecting piece.

[0008] Furthermore, the connecting member is a fixing pin, and the lower base and the upper base are connected by multiple fixing pins.

[0009] Furthermore, a second clearance window is provided at a position of the upper base corresponding to the mounting hole.

[0010] Furthermore, the bottom of the hinge arm is an inner groove, the top of the upper base is adapted to the shape of the inner groove, and the top of the upper base is snap-fitted with the inner groove.

[0011] The beneficial effects achieved by the utility model are:

[0012] The present invention can be installed as a whole without being disassembled. During installation, the staff first connects the fixing screws with the plate through the long holes to perform a preliminary positioning of the base. At this time, the device is preliminarily fixed on the plate. Then the staff uses tools such as a spirit level and a ruler to further determine the installation position of the device. If the installation is not level enough, the side of the base can be knocked with a tool to adjust the overall level. When it is determined that the installation is level and the position is accurate, another fixing screw can be used to pass through the positioning hole to connect with the plate. At this time, the position of the base is locked. In this way, the installation position of the device can be accurate and kept level. The design of the work window allows the staff to directly insert a screwdriver into the interior of the device for installation, which makes installation more convenient.

[0013] After the installation is completed, the device does not need to adjust the position of the hinge arm in the width direction again, which can achieve accurate one-time installation and ensure that the hinge arm and the base will not deform in the up and down directions. After long-term use, the position of the door panel will not shift. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0019] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0021] like Figures 1 to 4 As shown, the utility model provides an easy-to-install hardware hinge, including a base 1, a hinge arm 2 is arranged on the upper part of the base 1, one end of the hinge arm 2 is hinged to the hinge cup 4 through a connecting rod assembly 3, and a plurality of groups of mounting holes are provided at the bottom of the base, each group of mounting holes includes at least a long hole 5 and a circular positioning hole 6, the hinge arm is connected to the base through an adjusting screw, and the angle between the hinge arm and the base can be adjusted by adjusting the screw. This design is a prior art and will not be repeated here. A first makeshift window 7 is provided at the position of the hinge arm corresponding to the mounting hole, and the staff can pass a screwdriver-like installation tool through the first makeshift window to connect the fixing screw 9 to the plate through the mounting hole. Through this design, the hinge arm and the base do not need to be separated first to carry out the installation work as a whole.

[0022] The base comprises a lower base 101 and an upper base 102, which are fixedly connected by a connector, a fixed pin. The lower and upper bases are connected by multiple fixed pins 103. This design allows the base to be divided into two parts, facilitating production and reducing manufacturing costs. A second clearance window 104 is provided in the upper base, corresponding to the mounting hole. The hinge arm is connected to the upper base via an adjustment screw.

[0023] The bottom of the hinge arm is an inner groove, and the top of the upper base 102 is adapted to the shape of the inner groove. The top of the upper base 102 is snap-fitted with the inner groove. This design can improve the installation stability between the hinge arm and the upper base, and the angle between the hinge arm and the base can be adjusted by adjusting the screws. However, during the adjustment process, the two are stably installed in the width direction of the base and are not prone to deformation. This is more stable than existing hinges and has the obvious advantage of not being easily deformed after long-term use. Since the existing hinges are difficult to accurately adjust the base installation position, an offset adjustment structure is additionally provided between the hinge arm and the base in the width direction, resulting in a complex structure and an unstable structure, which is prone to deformation after long-term opening and closing.

[0024] The advantage of the present invention is that the device can be installed as a whole without being disassembled. During installation, the staff first connects the fixing screws 9 through the long holes to the plate and performs preliminary positioning of the base. At this time, the device is initially fixed to the plate. Then the staff uses tools such as a spirit level, a ruler, and a screwdriver to further determine the installation position of the device. If the installation is not level enough, the overall level can be adjusted by knocking on the side of the base with a tool. After determining that the installation is level and the position is accurate, another fixing screw can be used to connect it to the plate through the positioning hole. At this time, the position of the base is locked. In this way, the installation position of the device can be accurately installed and kept level. The design of the work window allows the staff to directly insert the screwdriver into the interior of the device for installation, making installation more convenient. After the installation is completed, the device does not need to adjust the position of the hinge arm again in the width direction, and can achieve accurate one-time installation. It can also ensure that the hinge arm and the base will not deform in the vertical direction. The base part only needs to be designed into two parts to achieve the function of the existing hinge. After long-term use, the position of the door panel will not shift.

[0025] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
