Abstract
The utility model discloses a kind of oil cylinder bulb, comprise spherical shell and mandrel, offer through hole in described spherical shell, mandrel sleeve is in through hole; The top of the ball core on described mandrel is up-narrow and down-wide billiard table, and its underpart is the semiglobe that diameter is less than billiard table lower end surface diameter; Its end face of billiard table part of described ball core coordinates with upper ball base, and the hemispherical portion of ball core coordinates with rubber parts, and described upper ball base and rubber parts are all arranged in through hole; Also be provided with pad in described through hole, rubber parts abuts with pad.Advantage is: structure of the present utility model is simple, and ball core is less than the hemisphere of billiard table diameter combination by billiard table and diameter can allow its inner space is broader, cost is lower; The upper ball base core that can concede points operationally directly is in contact with it, and prevents the friction of ball core and spherical shell and affects working life; It is better that rubber parts compares its resiliency of original spring structure, longer service life.
Description
Technical field
The utility model belongs to component of machine technical field, especially relates to the oil cylinder bulb on a kind of agricultural hydraulic equipment.
Background technique
Oil cylinder bulb is one of vitals of common agricultural hydraulic equipment, and its Main Function is the effect of connection and adjustment direction.The end face of the spherical part both sides of existing its internal mandrel of oil cylinder bulb directly contacts with spherical shell, then arranges spring in lower end surface and have by it between certain buffer area; The oil cylinder bulb of this structure not only complex structure, cost is higher and easily affect its life-span in life-span because mandrel bulb part and spherical shell rub for a long time; And spring is owing to being rigid bullet part, its cushioning effect is not good, easily loses efficacy after permanent use; The spherical shell being exactly existing oil cylinder bulb is in addition split-type structural, this structure spherical shell technique comparatively complicated, cost is also higher; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of oil cylinder bulb, and it has the feature in structure simple, with low cost and working life.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of oil cylinder bulb, comprises spherical shell and mandrel, offers through hole in described spherical shell, and mandrel sleeve is in through hole; The top of the ball core on described mandrel is up-narrow and down-wide billiard table, and its underpart is the semiglobe that diameter is less than billiard table lower end surface diameter; Its end face of billiard table part of described ball core coordinates with upper ball base, and the hemispherical portion of ball core coordinates with rubber parts, and described upper ball base and rubber parts are all arranged in through hole; Also be provided with pad in described through hole, rubber parts abuts with pad.
Lower ball base is provided with between the hemispherical portion of described rubber parts and ball core.
Described rubber parts is rubber ring.
Dust-proof cover is connected with between described spherical shell and mandrel.
The upper end portion of described spherical shell is provided with flange, and dust-proof cover is provided with hypotenuse, flange and the mutual clamping of hypotenuse.
The upper end outer circumferential face of described dust-proof cover is provided with individual layer collar, and the lower end periphery face of dust-proof cover is provided with double-deck collar.
Described spherical shell is integral type structure.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, the top of the ball core on mandrel is up-narrow and down-wide billiard table, bottom is the semiglobe that diameter is less than billiard table lower end surface diameter, this structure of ball core compares original spherical structure, and it more saves material while effectively saving inner space, allows cost of production be reduced; The upper ball base core that can concede points operationally directly is in contact with it, and prevents the friction of ball core and spherical shell and affects working life; It is better that rubber parts compares its resiliency of original spring structure, longer service life; Spherical shell of the present utility model is integral type structure, and this structure is when making, and technique is simple, cost is also comparatively cheap.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment 1, as shown in Figure 1: a kind of oil cylinder bulb, comprises spherical shell 10, mandrel 20, upper ball base 22 and dust-proof cover 30.Spherical shell 10 is integral type structure, and this integral structure technique is comparatively simple, and cost is also lower.Offer through hole 11 in spherical shell 10, mandrel 20 sleeve is in through hole 11.Mandrel 20 is divided into core bar 26 and ball core 21, and the bottom of core bar 26 is connected with the billiard table on ball core 21, and billiard table is up-narrow and down-wide structure, and the bottom of billiard table is connected with hemisphere, and the diameter of hemisphere is less than the diameter of billiard table lower end surface.Its end face of billiard table part of ball core 21 coordinates with upper ball base 22, upper ball base 22 is arranged in through hole 11, and its end face is close to the interior edge face of spherical shell 10, this structure core 21 that can concede points operationally directly contacts with upper ball base 22, prevents ball core 21 from directly contacting with the interior edge face of spherical shell 10 and causing the shortening in working life.The hemispherical portion of ball core 21 coordinates with rubber parts 23, and described rubber parts 23 is rubber ring, and the pad 24 that rubber ring is arranged in through hole 11 and its lower end surface and through hole 11 offsets; The rubber ring core 21 that can concede points operationally has certain cushioning effect, compares original rigid spring, and its cushioning effect is better and can use for a long time and not lose efficacy.
One end of dust-proof cover 30 is provided with hypotenuse 31, and the upper end portion of spherical shell 10 is provided with flange 12, hypotenuse 31 and the clamping of flange 12 phase, and its snap effect of clamping that such snap fit compares original projection and groove is better; The other end of dust-proof cover 30 is connected on mandrel 20.In order to make dust-proof cover 30 more fastening, the outer circumferential face of end is provided with individual layer collar 32 thereon, and the outer circumferential face of underpart is provided with double-deck collar 33, can effectively prevent dust-proof cover 30 from loosening after the time uses like this.
Embodiment 2, the structure of embodiment 2 and embodiment 1 substantially compared with, its difference is: between rubber parts 23 and the hemispherical portion of ball core 21, be provided with lower ball base 25, and can the concede points work of core 21 of lower ball base 25 is more stable.
