Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the staff of ordinary skill in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a wear-resisting hinge of bearing, including left blade 1 and right blade 2, one side of left blade 1 is equipped with first sleeve 3, two mounting grooves 4 are seted up to first sleeve 3's inboard, the equal swing joint in bottom of two mounting grooves 4 has steel ball 5, the middle part of first sleeve 3 runs through there is axis 6, the bottom threaded connection of axis 6 is in the inside of second sleeve 7, two sets of annular piece 8 are established to axis 6's inboard, a plurality of oilhole 9 has been seted up to axis 6's middle part side, axis 6's top is equipped with soft block 10, be connected between the top of soft block 10 through connecting rope and sealing plug 11.

In this embodiment, as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the number of the second sleeves 7 is two, and one ends of the two second sleeves 7 are respectively inserted into the two mounting grooves 4; can make the bearing capacity of hinge more firm that first sleeve 3 and second sleeve 7 are connected.

In this embodiment, as shown in fig. 2, 3 and 4, the middle shaft 6 sequentially penetrates through the soft block 10, the second sleeve 7, the steel ball 5 and the first sleeve 3 from top to bottom; the middle shaft 6 can enable the left blade and the right blade to be coaxial all the time during rotation, the left blade and the right blade cannot be deformed during rotation, the rotating smoothness is not affected, the service life is shortened, and meanwhile the bearing capacity of the hinge can be further enhanced through the middle shaft 6.

In this embodiment, as shown in fig. 2 and 3, a hole is left in the middle of the upper ring segment 8 of the two ring segments 8, the lower ring segment 8 is a conical closed structure, and a plurality of oil holes 9 are opened above the intersection of the central axes 6 of the two ring segments 8; when needs lubricate the hinge, can pour lubricating oil into through axis 6, lubricated ring segment 8 can play the direction drainage effect, introduces lubricating oil into among the oilhole 9 finally gets into steel ball 5 and two telescopic gaps, plays the lubrication action, reduces the wearing and tearing of hinge to ring segment 8 of below can prevent that lubricating oil from flowing into the inboard bottom of axis 6 and piling up extravagantly.

In this embodiment, as shown in fig. 2 and 3, steel bead grooves are formed in both the inner side of the first sleeve 3 and the bottom of the second sleeve 7; the steel ball groove can play limiting role to the steel ball 5, and the steel ball 5 is more attached to the upper sleeve and the lower sleeve.

In this embodiment, as shown in fig. 1 and 2, the left blade 1 and the right blade 2 are both provided with a plurality of fixing holes; the left blade 1 and the right blade 2 are installed on the required door and window through the fixing holes and matching screws and the like, and are used for connecting the door frame and the door panel.

The utility model discloses a use method and advantage: this kind of wear-resisting hinge of bearing is when the rolling, and the working process is as follows:

as shown in fig. 1, 2, 3 and 4, firstly, the hinge is installed through a plurality of fixing holes on the left blade 1 and the right blade 2 for connecting a door frame and a door panel, when the door panel needs to be rotated, the door panel drives the left blade 1 to rotate, the left blade 1 drives the first sleeve 3 to rotate, because the second sleeve 7 is installed in the installation grooves 4 at the two ends of the first sleeve 3, the two blades are connected more stably, the whole hinge has stronger bearing capacity, and the two sleeves and the steel balls 5 penetrate through the middle shaft 6 in the middle part to further enhance the bearing capacity of the hinge, and the two sleeves are always coaxial when rotating, so that the deformation of the left and right blades when rotating can not be caused, the smoothness of rotation is influenced, and the service life of the hinge is reduced, and steel ball 5 can reduce the frictional force between first sleeve 3 and the second sleeve 7, make the hinge more wear-resisting, and when needs lubricate the hinge, open sealing plug 11 at soft piece 10 middle part, pour lubricating oil into, the part can fall on the ring segment 8 of below from the opening at the first group ring segment 8 middle part in top after lubricating oil pours into, part lubricating oil then can flow down along the inner wall of axis 6 in addition, after the ring segment 8 contact with the top, in leading-in mounting groove 4 with lubricating oil under the guide effect of ring segment 8, play the lubrication action to steel ball 5 and two sleeves, ring segment 8 of below is the same effect, but below ring segment 8 is closed, prevent that lubricating oil from getting into 6 inboard bottoms of axis and piling up and causing the waste, it can to cover sealing plug 11 again after lubricating oil pours to the completion.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that there may be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the claimed invention.
