DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] 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.
[0023] The utility model provides a new door shaft assembly, such as Figures 1 - 5 As shown, it includes a lower seat 1 and an upper seat 3, the lower seat 1 is installed at the lower part of the door body, and the upper seat 3 is installed at the upper part of the door body. A bottom plate 2 is installed at the bottom of the lower seat 1, and the bottom plate 2 is fixed to the lower part of the door frame. The lower seat 1 is supported by the bottom plate 2, and a top plate 4 is installed on the top of the upper seat 3, and the top plate 4 is fixed to the upper part of the door frame. A convex column 23 is installed at the top of one end of the bottom plate 2, and a groove 231 is arranged on the top of the convex column 23. A steel ball groove 13 is arranged at the bottom of the lower seat 1, and a steel ball 14 is installed inside the steel ball groove 13. The steel ball 14 is stuck in the groove 231 to facilitate the flexible rotation of the lower seat 1.
[0024] In this embodiment, a mounting hole 21 is provided on the surface of the bottom plate 2 , and a side plate 22 is installed on the top of one side of the bottom plate 2 to facilitate the installation and fixation of the bottom plate 2 .
[0025] Specifically, a lower plug block 11 is installed on one side of the lower seat 1, an upper plug block 36 is installed on one side of the upper seat 3, and a fixing plate 41 is installed on one side of the top plate 4. The lower plug block 11 and the upper plug block 36 are conveniently connected to the socket of the door body to achieve fixation between the upper seat 1 and the lower seat 3 and the door body. The fixing plate 41 is conveniently connected to the door frame to achieve fixation of the top plate 4.
[0026] Furthermore, a lower shaft hole 12 is provided at the top of the lower seat 1, and an upper shaft hole 37 is provided at the bottom of the upper seat 3, so as to facilitate the connection and fixation between the upper seat 3 and the lower seat 1 through a pin shaft.
[0027] Furthermore, a slot 31 is provided at the top of the upper seat 3, a limiting column 33 is provided inside the slot 31, and a spring 32 is installed at the bottom of the limiting column 33. The spring 32 makes the limiting column 33 have a certain elasticity, so that the distance between the top plate 4 and the upper seat 3 can be adjusted, which is suitable for fine-tuning the upper seat 3. The limiting column 33 is supported by the spring 32 to prevent the door body from falling off accidentally.
[0028] Furthermore, a locking hole 34 is provided on one side of the upper seat 3, and a locking bolt 35 is connected to the inner thread of the locking hole 34. The end of the locking bolt 35 abuts against the outer wall of the limiting column 33 to ensure the fixation of the limiting column 33 after installation to prevent the door body from falling off.
[0029] Furthermore, a socket 42 is provided at the bottom of the top plate 4, and the top of the limit post 33 is inserted into the socket 42 in a mating manner, so as to fix the upper seat 3 on the top plate 4.
[0030] When the novel door hinge assembly of the present utility model is in use, first, the bottom plate 2 is fixed to the lower part of the door frame through the mounting holes 21. At the same time, the side plates 22 are used to further enhance the mounting stability of the bottom plate 2. Then, the lower seat 1 is installed on the lower part of the door body, and is fixed to the door body through the lower insertion block 11 and the socket of the door body.
[0031] Then, the upper seat 3 is installed on the upper part of the door body, and is fixed to the door body through the upper insertion block 36 and another socket of the door body. At the same time, the top plate 4 is fixed to the upper part of the door frame, and is connected to the door frame by using the fixing plate 41 to further enhance the mounting stability of the top plate 4.
[0032] After the lower seat 1 and the upper seat 3 are installed, the upper seat 3 and the lower seat 1 are connected by passing a pin shaft through the lower shaft hole 12 and the upper shaft hole 37, and relative rotation between them is realized. At this time, the steel ball 14 is stuck in the groove 231, which facilitates the flexible rotation of the lower seat 1.
[0033] When fine adjustment of the upper seat 3 is required, the locking bolt 35 can be rotated so that its end abuts against the outer wall of the limit post 33, thereby releasing the fixation of the limit post 33. Then, by using the elasticity of the spring 32, the limit post 33 is pushed to move in the slot 31, so as to adjust the distance between the top plate 4 and the upper seat 3. After the adjustment is completed, the locking bolt 35 is rotated again to fix the limit post 33 to prevent the door body from accidentally falling off.
[0034] Finally, the top of the limit post 33 is inserted into the socket 42 at the bottom of the top plate 4, so as to fix the upper seat 3 on the top plate 4. Thus, the installation and adjustment process of the novel door hinge assembly of the present utility model is all completed.
[0035] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model.
