Abstract
A kind of jack servo-unit, comprise base, oil body and valve body, base includes the attachment face for installing oil body and valve body, on attachment face, offer blind hole, and blind hole depth is 14-16mm, on the inwall of blind hole, be provided with screw thread; Oil body and valve body all offer through hole, fixing with bolt be connected with blind threaded through through hole.What the utility model changed traditional through hole be inserted in for bolt offers mode, changes traditional through through hole into blind hole, and, offer direction and offer from top to bottom by upwards offering to change into from base bottom.Structure design like this, when carrying out dismounting to oil body and valve body, not needing to be lifted by base more just directly to turn operation to bolt, simplifying jack servo-unit disassembling operations technique.In addition, bolt is set to the inside of jack servo-unit, decreases water, air and threaded bolt contacts probability, reduces the possibility that bolt gets rusty dramatically.
Description
Technical field
The utility model relates to lifts equipment technical field, more particularly, and particularly a kind of jack servo-unit.
Background technology
In mechanical field, usually all jack can be used in order to the larger mechanical equipment of quality can be lifted.For automobile, at needs more wheel change or when needing to overhaul at the bottom of to car, jack all can be used by automobile jack-up.For the ease of jack can be used like a cork, a kind of jack servo-unit is provided in prior art, this servo-unit comprises base, oil body and valve body, oil body and valve body are bolted and are arranged on base, and the set-up mode of bolt is pass from the bottom of base to be connected with valve body and oil body.The technical matters that this structure design exists is: bolt is from the bottom of base, and namely bottom surface is passed, and is no matter when installing or disassemble jack servo-unit, all needs servo-unit to lift, cause complicated operation; In addition, bolt exposes design, easily makes bolt get rusty, and servo-unit extremely just cannot be taken apart by rust in tapped bore.
Utility model content
(1) technical matters that will solve
Improve the simplicity of jack servo-unit dismounting.
(2) technical scheme
A kind of jack servo-unit, comprise base, oil body and valve body, described base includes the attachment face for installing described oil body and described valve body, on described attachment face, offer blind hole, described blind hole depth is 14-16mm, on the inwall of described blind hole, be provided with screw thread; Described oil body and described valve body all offer through hole, fixing with bolt to be blind threadedly connected with described through through hole.
Preferably, described oil body and described valve body are integral structure.
Preferably, one end of described valve body is provided with permanent seat, and described permanent seat offers through hole, and described permanent seat and described base offset; The cross-sectional plane of described oil body is circular, and a side of described permanent seat and described oil body joint has indent deep-slotted chip breaker, and described oil body is arranged on described indent deep-slotted chip breaker.
(3) beneficial effect
Designed by said structure, what the utility model changed traditional through hole be inserted in for bolt offers mode, changes traditional through through hole into blind hole, and, offer direction and offer from top to bottom by upwards offering to change into from base bottom.Structure design like this, when carrying out dismounting to oil body and valve body, not needing to be lifted by base more just directly to turn operation to bolt, simplifying jack servo-unit disassembling operations technique.In addition, bolt is set to the inside of jack servo-unit, decreases water, air and threaded bolt contacts probability, reduces the possibility that bolt gets rusty dramatically.

Fig. 2 is the local structure birds-eye view of jack servo-unit in the utility model embodiment;
In fig. 1 and 2, the corresponding relation of component names and accompanying drawing number is:
Base 1, oil body 2, valve body 3, blind hole 4, indent deep-slotted chip breaker 5.
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more; Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " rear end ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second ", " the 3rd " etc. only for describing object, and can not be interpreted as instruction or hint relative importance.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " is connected ", " connection " should be interpreted broadly, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, particular case the concrete meaning of above-mentioned term in the utility model can be understood.
Please refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is the local structure schematic diagram of jack servo-unit in the utility model embodiment; Fig. 2 is the local structure birds-eye view of jack servo-unit in the utility model embodiment.
The utility model provides a kind of jack servo-unit, comprise base 1, oil body 2 and valve body 3, base 1 includes the attachment face for installing oil body 2 and valve body 3, offers blind hole 4 on attachment face, blind hole 4 degree of depth is 14-16mm, on the inwall of blind hole 4, be provided with screw thread; Oil body 2 and valve body 3 all offer through hole, and fixing bolt is threaded with blind hole 4 through through hole.
Designed by said structure, what the utility model changed traditional through hole be inserted in for bolt offers mode, changes traditional through through hole into blind hole 4, and, offer direction and offer from top to bottom by upwards offering to change into bottom base 1.Structure design like this, when carrying out dismounting to oil body 2 and valve body 3, not needing to be lifted by base 1 more just directly to turn operation to bolt, simplifying jack servo-unit disassembling operations technique.In addition, bolt is set to the inside of jack servo-unit, decreases water, air and threaded bolt contacts probability, reduces the possibility that bolt gets rusty dramatically.
Particularly, oil body 2 and valve body 3 are integral structure, and in the utility model, oil body 2 and valve body 3 are metal construction, and it can adopt all-aluminium construction also can adopt steel design.
In the utility model, one end of valve body 3 is provided with permanent seat, and permanent seat offers through hole, and permanent seat and base 1 offset; The cross-sectional plane of oil body 2 is circular, and a side of permanent seat and oil body 2 joint has indent deep-slotted chip breaker 5, and oil body 2 is arranged on indent deep-slotted chip breaker 5.The above-mentioned improvement to valve body 3 structure can improve the compact conformation degree of jack servo-unit, thus makes the utility model volume more exquisite, portable.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by the utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand the utility model thus design the various embodiments with various amendment being suitable for special-purpose.
