DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a glass door which is easy to automatically reset. Figure 1-Figure 6 As shown, it includes a box body 1, the front of the box body 1 is rotatably connected to a door body 2 through a hinge, the hinge includes an upper hinge 4 located at the upper part of the door body 2 and a lower hinge located at the lower part of the door body 2, a spring 3 is connected between the upper hinge 4 and the door body 2, a door shaft 21 is installed on the side of the door body 2 close to the box body 1, one side of the upper hinge 4 is fixed on the box body 1, and the other side is rotatably connected to the door shaft 21. When the door body 2 is closed, the spring 3 pulls the door body 2 inward, and when the door body 2 is opened, as the angle of the door body 2 increases, The spring 3 is stretched, thereby generating a force that pulls the door body 2 inward. When the spring 3 passes the position of the door shaft 21, the spring 3 generates a force that pulls the door body 2 outward. An adjustment component 6 is installed at one end of the box body 1 close to the spring 3. The adjustment component 6 drives the spring 3 to move through the movement of the screw rod 62, thereby achieving fine-tuning of the upper end position of the spring 3. By fine-tuning the spring 3, it is ensured that the spring 3 is not inaccurately positioned after installation, which affects the opening and resetting actions of the door body 2.

[0025] In this embodiment, when the door body 2 reaches the maximum closing angle, the angle between the door body 2 and the front of the box body 1 is guaranteed to be 122 degrees. When it is greater than 122 degrees, the normally open operation of the door body 2 can be achieved.

[0026] Specifically, during the opening and closing action of the door body 2 , the spring 3 is always in a stretched state, ensuring that a tensioning force is applied to the door body 2 .

[0027] Furthermore, a first positioning screw 22 is installed on the door body 2, and a lower rod 31 is installed at one end of the spring 3. The end of the lower rod 31 is provided with a lower hanging hole 311, and the lower hanging hole 311 is rotatably connected to the first positioning screw 22, which facilitates the installation and disassembly of the spring 3 and facilitates the connection between the door body 2 and one end of the spring 3.

[0028] Furthermore, a fixing seat 5 is installed on the box body 1, and a second positioning screw 51 is installed on the fixing seat 5. An upper rod 32 is installed on the other end of the spring 3. An upper hanging hole 321 is provided at the end of the upper rod 32. The upper hanging hole 321 is rotatably connected to the second positioning screw 51 to facilitate the connection between the box body 1 and one end of the spring 3.

[0029] Furthermore, during the opening process of the door body 2, when the spring 3 is located on the left side of the door shaft 21, the direction of the force of the spring 3 is toward the left side of the door shaft 21, driving the door body 2 to close; when the spring 3 is located on the right side of the door shaft 21, the direction of the force of the spring 3 is toward the right side of the door shaft 21, driving the door body 2 to be in an open state; when the spring 3 coincides with the door shaft 21, it is the maximum closing angle.

[0030] Furthermore, the outer ends of the first positioning screw 22 and the second positioning screw 51 are both installed with limiting nuts, which facilitates locking of the spring 3 after installation, prevents the spring 3 from falling off during operation, and also facilitates the disassembly operation of the spring 3.

[0031] Furthermore, the adjustment component 6 includes a fixed sleeve 61, a screw rod 62 is arranged inside the fixed sleeve 61, a handle 67 is installed at one end of the screw rod 62, a screw rod slider 63 is installed on the screw rod 62, a telescopic rod 64 is installed on one side of the top of the screw rod slider 63, one end of the telescopic rod 64 passes through the fixed sleeve 61 and is installed with a movable rod 65, a column 66 is installed at the outer end of the movable rod 65, one end of the spring 3 is hung on the column 66, and the screw rod slider 63 is driven to move by rotating the handle 67 to realize the movement of the movable rod 65, thereby making the column 66 move, thereby fine-tuning the position of the spring 3, so that when the door body 2 is opened and closed, the spring 3 is in the designated position designed in the utility model, thereby ensuring the accurate opening and resetting of the door body 2.

[0032] When the glass door of the utility model which is easy to automatically reset is used, first the initial state is: the door body 2 is in a closed state, at this time the spring 3 is in a certain tension state, and there is an inward tensioning force on the door body 2 to ensure that the door body 2 is tightly closed.

[0033] Door opening process: When the user needs to open the door body 2, the tension of the spring 3 must be overcome. As the door body 2 gradually opens, the spring 3 is gradually stretched, and its tension also increases. In this process, the spring 3 always exerts an inward pulling force on the door body 2, trying to pull it back to the closed state.

[0034] Change of spring action: When the door body 2 is opened to a certain angle, so that the spring 3 passes the position of the door shaft 21, the pulling direction of the spring 3 will change from the original inward pull to the outward pull. This design makes the spring 3 help keep the door body 2 open after it is opened to a certain angle.

[0035] Maximum closing angle: When the spring 3 overlaps with the door shaft 21, the door body 2 reaches the maximum closing angle, that is, the angle between the door body 2 and the front of the box body 1 is 122 degrees. If the door body 2 is opened at an angle greater than 122 degrees, the direction of the force of the spring 3 changes, and the door body 2 will remain in the normally open state.

[0036] Easy to disassemble and install: The two ends of the spring 3 are connected to the door body 2 and the box body 1 through the first positioning screw 22 and the second positioning screw 51 respectively. This design makes the installation and disassembly of the spring 3 simple and convenient. At the same time, the use of the limit nut ensures the stability of the spring 3 after installation and prevents it from falling off during operation.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
