Fixed set coordinates grafting with shaft core, mounting groove is provided on above-mentioned fixing sleeve, above-mentioned rotation is set in mounting groove and and shaft core
Cooperation is socketed, and is provided with annular groove in above-mentioned shaft core, above-mentioned steel ball is fitted in groove, above-mentioned fixing sleeve and support ring
Corresponding surface be provided with and the matched mating groove of steel ball, above-mentioned steel ball is rolled with shaft core, fixing sleeve and support ring to be coordinated.
As an optimization, the top surface of above-mentioned rotary sleeve is flushed with the top surface of fixing sleeve, above-mentioned rotary sleeve and shaft core and fixing sleeve
Between clearance fit.
As an optimization, the outer wall of above-mentioned fixing sleeve is provided with card slot, and the inner wall of above-mentioned shell is provided with snap ring, above-mentioned snap ring with
Card slot cooperation clamping.
As an optimization, it is sealed and is coordinated by sealing ring between above-mentioned fixing sleeve and shaft core.
Three, the beneficial effects of the utility model
It is provided with rotation auxiliary body in the utility model hydraulic hinge, shaft core can be assisted to rotate in use,
It is allowed to more smooth when positive and negative rotation, improves the practicability of hydraulic hinge.
Description of the drawings
Fig. 1 is the sectional view of the utility model hydraulic hinge；
Fig. 2 is the portions the A enlarged drawing of Fig. 1；
Fig. 3 is the exploded view of the utility model rotation auxiliary body.
In figure, 1 is shell, and 2 be shaft core, and 3 be spring, and 4 be fixing sleeve, and 5 be rotary sleeve, and 6 be steel ball, and 7 be support ring, 8
It is sealing ring for card slot, 9,10 be mating groove.
Specific implementation mode
The utility model hydraulic hinge is described further below in conjunction with the accompanying drawings：
Embodiment one：As shown in Figures 1 to 3, the utility model hydraulic hinge includes shell 1, is set in above-mentioned shell 1
The spring 3 for being equipped with shaft core 2 and being socketed with shaft core 2, wherein 2 one end of above-mentioned shaft core is provided with rotation auxiliary body, rotation auxiliary
Mechanism is mounted in shell 1 and connects and fixes with shell 1, above-mentioned rotation auxiliary body by fixing sleeve 4, rotary sleeve 5, steel ball 6 and
Support ring 7 form, in the present embodiment, above-mentioned rotary sleeve 5 can be made of plastics or metal, wherein metal can be copper, aluminium,
Iron etc., or other alloys；The outer wall of above-mentioned fixing sleeve 4 is provided with card slot 8, and the inner wall of above-mentioned shell 1 is provided with snap ring, above-mentioned
Snap ring is clamped with the cooperation of card slot 8, is so designed, and can ensure that fixing sleeve 4 has good installation relation with shell 1.
Above-mentioned fixing sleeve 4 coordinates grafting with shaft core 2, and is matched by the sealing of sealing ring 9 between fixing sleeve 4 and shaft core 2
It closes, mounting groove is provided on above-mentioned fixing sleeve 4, above-mentioned rotary sleeve 5, which is arranged in mounting groove and coordinates with shaft core 2, to be socketed, specifically
Say, the top surface of above-mentioned rotary sleeve 5 is flushed with the top surface of fixing sleeve 4, gap between above-mentioned rotary sleeve 5 and shaft core 2 and fixing sleeve 4
Cooperation.
Annular groove is provided in above-mentioned shaft core 2, above-mentioned steel ball 6 is fitted in groove, above-mentioned fixing sleeve 4 and support
The corresponding surface of ring 7, which is provided with, to be rolled with 6 matched mating groove 10 of steel ball, above-mentioned steel ball 6 with shaft core 2, fixing sleeve 4 and support ring 7
Dynamic cooperation.
In use, hinge drives shaft core 2 to rotate, when shaft core 2 rotates, with 2 matched steel ball 6 of shaft core and rotation
Pivoted housing 5 can assist shaft core 2 to rotate, and keep the rotation of shaft core 2 more smooth, specifically, when shaft core 2 rotates, steel ball 6 and shaft core 2
It generates and rolls cooperation, at the same time, shaft core 2 can be followed to rotate with the rotary sleeve 5 of 2 clearance fit of shaft core, further increase shaft
The flexibility of rotation.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
