Description

Technical Field

[0001] The utility model relates to the technical field of door hinges, in particular to a glass door hinge. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid bodies and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. The existing glass door clamp hinge is mainly composed of a first clamp block, a second clamp block and a mounting seat, wherein the inner side surface of the first clamp block is protrudingly provided with a hinge seat, and the hinge seat is provided with a hinge groove. The mounting seat includes a mounting plate and a hinge block protruding from the mounting plate. The hinge block is hingedly mounted in the hinge groove through a rotating shaft. The second clamp block and the first clamp block are fastened together and are respectively provided with air avoidance grooves corresponding to the hinge grooves. When in use, the glass door edge is installed between the first clamp block and the second clamp block and is clamped and fixed by the first and second clamp blocks. The mounting seat is fixed to a fastening surface such as a wall or door frame through its mounting plate. The glass door can be opened or closed by pushing, pulling and turning the glass door so that the first and second clamp blocks rotate around the hinge block.

[0003] According to the "A Glass Door Clamp Hinge" disclosed in Chinese Patent Publication No. CN 214886322 U, when the glass door is closed, the positioning wheel always maintains contact with the arcuate wall of the arcuate free end of the hinge block under the tension of the spring until the clamping block rotates to position the positioning wheel and cooperate with the positioning groove of the arcuate free end of the hinge block, so that the glass door will not be loosely closed due to inertial swing; when the glass door is opened, the positioning wheel slides out of the positioning groove and always maintains contact with the arcuate wall of the arcuate free end of the hinge block under the tension of the spring, which can make the glass door open more smoothly. The hinge block is provided with a rotating shaft hole through it, and plastic rings are installed on the openings at both ends of the rotating shaft hole. The rotating shaft is installed in the rotating shaft hole, and the two ends pass through the plastic rings to protrude toward the two sides of the hinge block and are installed on the two side walls of the hinge groove. The plastic rings protrude toward the sides of the hinge block and contact the side walls of the hinge groove, which can avoid direct contact and collision between the hinge block and the side walls of the hinge groove, resulting in noise when the glass door is opened or closed, making it quieter when opening and closing.

[0004] However, the above device has the problem that most of the hinges for glass doors cannot be effectively protected during use, and the screws are exposed to the outside for a long time and are prone to rust, causing the glass door to sink and become unable to open and close. Utility Model Content

[0005] The purpose of the present invention is to provide a glass door hinge to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a glass door hinge, comprising a main structure and a protective structure, wherein the outer wall of the main structure is fixedly connected to the protective structure;

[0007] The main structure includes a fixed seat, one end of which is vertically hinged with a movable seat through a rotating shaft, a fixing groove is opened on the outer wall of the fixed seat, a fixing screw is threadedly connected inside the fixing groove, a clamping block is fixedly installed on the front of the fixed seat by the fixing screw, and a sealing cover plate is clamped on the outer wall of the fixed seat.

[0008] Preferably, fixing grooves are provided on the outer walls on both sides of the fixing seat, and fixing blocks are provided inside the fixing grooves, and the top of the fixing blocks is semicircular.

[0009] By setting the top of the fixing block to be semicircular, the fixing block can be better disengaged and inserted into the fixing groove and the positioning groove, which facilitates the installation and removal of the sealing cover plate.

[0010] Preferably, a return spring is fixedly connected to the inner bottom wall of the fixing groove, and the top of the return spring is fixedly connected to the bottom of the fixing block.

[0011] Preferably, a positioning groove is provided on the inner wall of the sealing cover plate, and the shape and size of the positioning groove are adapted to the shape and size of the fixing groove.

[0012] Preferably, a fixing hole is provided in the middle of the outer wall of the movable seat, positioning holes are provided on both sides of the fixing hole, and the positioning holes are provided at the four corners of the movable seat.

[0013] By setting fixing holes and positioning holes at the center and four corners of the movable seat, fasteners such as screws can stably fix the movable seat on the glass door.

[0014] Preferably, the protective structure includes a telescopic rod, a buffer spring is sleeved on the outer surface of the telescopic rod, and a protective plate is fixedly connected to the top of the telescopic rod.

[0015] Preferably, the top of the buffer spring is fixedly connected to the bottom of the protective plate, the bottom of the buffer spring is fixedly connected to the top of the sealing cover plate, and a buffer sponge layer is provided on the outer surface of the protective plate.

[0016] By providing a buffer sponge layer, the impact force of external impact is buffered, thereby reducing damage to the hinge.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] First, the utility model installs the sealing cover plate on the fixing seat. When the fixing groove on the fixing seat is aligned with the positioning groove on the sealing cover plate, the return spring in the fixing groove exerts an outward force on the fixing block, so that the fixing block is separated from the fixing groove and snapped into the positioning groove, thereby completing the fixed installation of the sealing cover plate. The sealing cover plate seals and protects the screws exposed to the outside, preventing the screws from rusting and causing the glass door to sink, making it impossible to open and close. The structure is simple and easy to disassemble and assemble, making it convenient for staff to perform maintenance and replacement.

[0019] Second, the present invention further protects the hinge by providing a telescopic rod, a buffer spring and a protective plate, thereby preventing the hinge from being damaged due to accidental collision with external objects, thereby improving the protection capability of the hinge.
