Abstract
The invention discloses a thread connecting device, which comprises a bolt and a nut, wherein the bolt and the nut are provided with internal and external threads respectively and engaged with each other; the thread connecting device also comprises a gasket, wherein the gasket comprises a body and an outwards bent elastic cantilever which are integrally formed; and the front end of one of the bolt and the nut is provided with a ratchet which is matched with the elastic cantilever of the gasket. When the bolt and the nut are loosened, a clearance is formed between the bolt and the nut, the elastic cantilever rebounds in the clearance to resist the ratchet, the ratchet is resisted, and movement between the bolt and the nut stops, so that the purpose of preventing loosening is fulfilled.
Description
Technical field
The present invention relates to a kind of screw connection, comprise screw bolt and nut, have internal and external threads respectively, the connection of intermeshing.
Background technique
In daily life, the device that couples together by screw bolt and nut is seen everywhere, such as tables and chairs, furniture, terminal box or the like.But we run into after object assembling, repeated disassembled and assembled, vibrations through regular meeting, and the interlock between the screw bolt and nut is loosening, even the phenomenon that can't assemble occurs.In order to address this problem, there is the people between screw bolt and nut, to place packing ring, but because the packing ring top and bottom all are the planes, so anti-loosing effect is not good.Chinese patent publication number: CN2536834 discloses a kind of locking self-locking thread, improve at the bottom of its double thread tooth and the inclination angle between the crest, the thread profile of screw bolt and nut is fixed on angle 60 degree, to eliminate the gap between Bottom of Thread and the crest, it is even to make that whole screw thread clamps load allocating, improves anti-loosening property.The shortcoming of this scheme is the processing request height to screw bolt and nut, and difficulty of processing strengthens, if in case the screw thread of producing does not reach consistent predetermined angular with the nut tooth form, just do not have anti-loosing effect.
Summary of the invention
The purpose of this invention is to provide a kind of screw connection, not only can effectively reach locking purpose, and easy to process.
For this reason, the technical solution adopted in the present invention is such: screw connection comprises screw bolt and nut, have internal and external threads respectively, the connection of intermeshing, it is characterized in that: it also comprises a pad, pad comprises the body and a bandy elastic cantilever of global formation; The front end of one of them parts has ratchet in the screw bolt and nut, matches with the elastic cantilever of pad.
The present invention is further improved, and pad is a n shape, has outstanding elastic tongue piece on its body.
The present invention further improves, and the bolt front end is fixed with one grade of shoulder, and pad is inserted between bolt body and the shelves shoulder; The nut front end has ratchet.
Further improve, bolt body is provided with one in the pad insert division and stops end, and the elastic tongue piece of pad is against and stops on the end.
One pad is arranged between the screw bolt and nut of the present invention, and this pad has a bandy elastic cantilever, and fashionable when screw bolt and nut is twisted, elastic cantilever is pressed towards shim body, when screw bolt and nut twist be incorporated into the position after, elastic cantilever is pressed close to the shim body surface.One of them front end of screw bolt and nut of the present invention has ratchet, cooperates with the pad elastic cantilever, and elastic cantilever props up ratchet, and making between the screw bolt and nut can only positive movement and can not backward motion, thereby reaches locking purpose.
In order to reach better anti-loosing effect and economical with materials cost, preferably pad integral body is struck out n shape, elastic cantilever cooperates with the ratchet of nut front end near the end of n shape; The root two ends of n shape pad are provided with outwards outstanding elastic tongue piece, and the elastic tongue piece opening direction is opposite with the elastic cantilever direction of extension.The front end of bolt is fixed with the shelves shoulder, and the purpose that elastic tongue piece is set on the pad is a fixing bolt.
During use, pad is positioned between the screw bolt and nut, the elastic tongue piece of pad is filled in the space between bolt body and the shelves shoulder, because bolt body is provided with at the pad place of filling in and stops end, stop that distance is less than the front end of elastic tongue piece perk and the perpendicular distance between the shim body between end and the shelves shoulder, therefore when elastic tongue piece is filled in, elastic tongue piece meeting stress deformation, but when by after stopping end, distance between bolt body and the shelves shoulder increases, elastic tongue piece resilience, tongue piece front end prop up and stop end, have played the effect of fixing bolt.After screw bolt and nut engagement, the elastic cantilever of pad is pressed close to shim body, if loosening between the screw bolt and nut, elastic cantilever then resilience props up ratchet on the nut, stops between the screw bolt and nut further loosening.Simultaneously, because the elastic tongue piece of pad plays the effect of fixing bolt, strengthened the pad anti-loosing effect.
If want to unclamp connection set, only need tool using with the elastic cantilever perk, make elastic cantilever no longer prop up the ratchet of nut, just can be so that connection set unclamps.
Production and processing of the present invention and easy to operate, anti-loosing effect is good.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in more detail.
Fig. 1 is a schematic representation of the present invention.
Fig. 2 is user mode figure of the present invention.
Fig. 3 is the longitudinal section schematic representation of user mode of the present invention.
Fig. 4 is the right elevation of pad of the present invention.
Fig. 5 is the stereogram of pad of the present invention.
Embodiment
Referring to Fig. 1 and Fig. 2.Have a bolt 9 on the terminal box box body 1, bolt 9 and nut 2 engagements, resilient pad 4 is between bolt 9 and nut 2, and cable 3 passes bolt 9 and nut 2.When loosening when the space occurring between nut 2 and the bolt 9, the elastic cantilever 6 on the resilient pad 4 opens, and props up the ratchet 5 of nut 2 front ends.
Referring to Fig. 3, Fig. 4, Fig. 5.Resilient pad 4 is n shape, respectively is provided with an elastic tongue piece 7 near n shape two roots, is provided with an elastic cantilever 6 near near the end of resilient pad 4.The opening direction of elastic tongue piece 7 is opposite with the direction of extension of elastic cantilever 6.The front end of bolt 9 is fixed one grade of shoulder 8, and the elastic tongue piece 7 of resilient pad 4 is filled in the space between bolt 9 and the shelves shoulder 8, and the front end of elastic tongue piece 7 withstands on stopping on the end 10 of bolt 9.Elastic cantilever 6 geared nuts 2 cooperate with the ratchet of nut 2.
Certainly, the present invention also can adopt and have outstanding stuck point or other be provided with and replace elastic tongue piece on shim body, as long as the effect of playing is identical with the elastic tongue piece effect, all falls within protection scope of the present invention.
