fig. 2 is a top view of the vertical adjustment hinge according to the embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.
As shown in fig. 1 and 2, the present invention provides a vertical adjustment hinge, which includes a door leaf hinge plate 1, a door frame hinge plate 2, a pin shaft 3, an upper shaft sleeve 4, a lower shaft sleeve 5, a middle shaft sleeve 6 and an adjustment nut 7;
the upper shaft sleeve 4, the middle shaft sleeve 6 and the lower shaft sleeve 5 are sequentially sleeved on the upper part, the middle part and the lower part of the pin shaft 3; an adjusting distance is reserved between the upper end and the lower end of the middle shaft sleeve 6 and between the upper shaft sleeve 4 and the lower shaft sleeve 5; the adjusting nut 7 is sleeved on the shaft and arranged below the middle shaft sleeve 6, and the periphery of the shaft is provided with a thread matched with the adjusting nut 7;
the door leaf hinge plate 1 is connected with the middle shaft sleeve 6, and the door frame hinge plate 2 is connected with the upper shaft sleeve 4 and the lower shaft sleeve 5.
In the embodiment, the upper end part of the pin shaft 3 is sleeved with a first deep groove ball bearing 9; the lower end of the pin shaft 3 is sleeved with a second deep groove ball bearing 10, and the bottom end of the pin shaft 3 is sleeved with a thrust ball bearing 8. The thrust ball bearing 8 plays a role in bearing at the bottom of the pin shaft 3. The deep groove ball bearings are arranged in the upper shaft sleeve 5 and the lower shaft sleeve 5 of the door frame hinge plate 2 and the upper end and the lower end of the pin shaft 3, and can fix the pin shaft 3 and enable the pin shaft 3 to rotate left and right.
In this embodiment, the spacer 13 is disposed between the thrust ball bearing 8 and the second deep groove ball bearing 10, so as to better ensure the stress of the thrust ball bearing 8.
In this embodiment, a dust cap 11 is provided between the insertion opening of the lower sleeve 5 and the gap of the shaft, and a shaft cap 12 is provided at the end of the upper sleeve 4 to prevent dust from falling into the sleeve.
In the embodiment, when the door leaf sinks or the upper seam and the lower seam of the door leaf are staggered, the door leaf can be moved to move up and down for adjustment through rotating the adjusting round nut on the adjusting hinge pin shaft 3. When the door is adjusted upwards, one hinge is adjusted, namely the door leaf hinge plate 1 connected with the middle shaft sleeve 6 is communicated with the door leaf to be lifted up through screwing the adjusting nut 7 upwards, other hinges on the door leaf can be automatically adjusted upwards, and round nuts on other hinges are sequentially screwed after adjustment, so that the upward adjustment on the door is completed. When the door leaves are downwards adjusted, the round nuts on the hinges on the door leaves are sequentially downwards rotated according to the required size.
