Abstract
A nut assembly with fixed torque comprises a screw rod and a nut assembly matched with threads of the screw rod. The nut assembly with the fixed torque is characterized in that the nut assembly comprises a gasket, a nut inner sleeve and a nut outer sleeve. A section of the nut outer sleeve is of a concave shape and two ends of the section are communicated with each other, the nut inner sleeve is positioned inside the nut outer sleeve and is limited by the gasket at a free end of the nut outer sleeve in a matched mode. Outer teeth are installed on the outer wall of the nut inner sleeve, inner teeth are installed on the inner wall of the nut outer sleeve, and the outer teeth and the inner teeth are meshed with each other in a rotating mode along an opposite direction. Due to the fact that teeth meshed with each other in a rotating mode are installed on the nut outer sleeve and the nut inner sleeve and a fixed torque value is set, the nut assembly can make a 'da da' sound and can be used to prompt a user that a nut is screwed in place when the given torque value is reached during a screwing up process of the nut, and therefore further screwing can not cause damage to the nut assembly with the fixed torque, and under-screwing or over-screwing during the screwing up process of the nut using this structure can be avoided. The nut assembly with the fixed torque has the advantages of being simple and reasonable in structure, reliable in function, compact in parts matching and the like and can be widely applied to bathroom industry.
Description
Technical field
The utility model relates to a kind of nut, specifically a kind ofly decides the torque nut assembly, mainly is applicable to sanitaryware.
Background technique
In the existing sanitary ware industry, cover plate is connected with the toilet pottery, mainly is to lock by nut and screw rod.Number be that CN201185904 discloses a kind of installation structure of toilet seat cover board on January 28th, 2009 such as Chinese patent literature, longitudinal sliding block, bolt and nut that its structure comprises two bearings that are articulated in the lavatory lid rear portion, the transverse slider that cooperates with bearing respectively, slides at this transverse slider; Bearing is provided with the fluting that makes the transverse slider transverse shifting, and transverse slider is provided with the rectangular through-hole that makes longitudinal sliding block move, and longitudinal sliding block middle part is provided with the tapped hole that bolt cooperates, and bolt is fixed at behind the matching hole that passes toilet on the longitudinal sliding block by nut check.So that bolt can rely on two slide blocks vertically to have adjustable space horizontal reaching, this large-scale regulative mode can be regulated arbitrarily for the position of matching hole on the toilet, and then with a nut check.It is said, this structure can make the toilet of the applicable multiple pitch-row of lavatory lid, the restriction of specially not joined, reaching the function of rapid-assembling, installation fitting can ease of assembly with disassemble, also make things convenient for the lavatory lid packing.But, when the nut of this structure is connected with nut, or just twist less than the required firm power of locking cover plate, cause connection unreliable, easily cause getting loose of cover plate, form potential safety hazard; Tool using comes fastening nut, and is easily excessive because of torsion, causes the irrecoverability of screw rod or nut to destroy, and may cause sliding tooth and the not tight cover plate, or the dismounting difficulty.Therefore, be necessary further improvement.
The model utility content
The purpose of this utility model aims to provide a kind of simple and reasonable, reliable in function, each part and cooperates the compact torque nut assembly of deciding, to overcome deficiency of the prior art.
Decide the torque nut assembly by this purpose design a kind of, comprise screw rod, and the nut assembly that cooperates with screw flight, it is characterized in that nut assembly comprises pad, nut inner sleeve and nut overcoat, the nut overcoat cross section is spill and two ends communicate, the nut inner sleeve is positioned in the nut overcoat, cooperates spacing by pad in the nut overcoat free end.
Described nut outer wall of inside race is provided with external tooth, and the nut overcoat inwall is provided with internal tooth, external tooth and the mutual engagement in rotation of internal tooth opposite direction.
Described nut inner sleeve is interior empty cylindrical shape, and inwall is provided with the screw thread that cooperates with screw flight.
Described nut overcoat outer wall is rounded, triangle, rectangle or polygonal.
Described nut inner sleeve and nut overcoat are that plastics are made.
Nut assembly of the present utility model is by arranging the tooth of mutual engagement in rotation in nut overcoat and nut inner sleeve, and a fixing torque value is set, in the nut screwing clamping process, when reaching the torque value of this setting, nut assembly just can be found the sound that raps, and the prompting user nut has been turned round and put in place, also can not cause damage and turn round to this product again, utilize the nut of this structure to tighten and namely can not owe in the process to turn round, also can not cross and turn round.It has simple and reasonable, reliable in function, and each part cooperates the characteristics such as compact.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, this decides the torque nut assembly, comprises screw rod 1, and with the nut assembly of screw rod 1 screw-thread fit, nut assembly comprises pad 2, nut inner sleeve 3 and nut overcoat 4, nut inner sleeve 3 and nut overcoat 4 are made for plastics; Nut overcoat 4 cross sections are spill and two ends communicate, and nut inner sleeve 3 is positioned in the nut overcoat 4, cooperate spacing by pad 2 in nut overcoat 4 free ends; Nut inner sleeve 3 outer walls are provided with external tooth 3.1, and nut overcoat 4 outer walls are the class rectangle, and inwall is provided with internal tooth 4.1, described external tooth 3.1 and the mutual engagement in rotation of internal tooth 4.1 opposite directions; Nut inner sleeve 3 is interior empty cylindrical shape, and inwall is provided with the screw thread with screw rod 1 screw-thread fit.
During use, referring to Fig. 2-Fig. 4, nut assembly is in the locking process, when tightening overcoat 4, because the effect of overcoat tooth 4.1 and inner sleeve tooth 3.1 can drive inner sleeve 3 and rotate together, until nut assembly and screw rod 1 tighten.Arrow is inner sleeve 3 and overcoat 4 sense of rotation separately among Fig. 4.
When the user need to back-out nut assembly and screw rod 1, referring to Fig. 5-Fig. 6, only need this moment just can unscrew easily nut assembly and screw rod 1 to the opposite direction rotation of internal tooth 3.1 with external tooth 4.1 interlocking patterns.Arrow is inner sleeve 3 and overcoat 4 sense of rotation separately among Fig. 6.
Referring to Fig. 7-Fig. 9, when nut assembly arrives ceramic 5 bottom surface, fit in its pad 2 meetings and ceramic 5 bottom surfaces, and pad 2 and pottery 5 are at this moment without relative movement; Pad 2 and inner sleeve 4 mutual kinetic friction; Because the friction of the surface of contact of pad 2 and inner sleeve 3 in rundown process reduces nut in the drag effect of rundown process much smaller than the friction between pad 2 and the pottery 5 so play.When the torsion of locking nut reaches the 3.4N/m of setting, Interference size between the tooth of inner sleeve 3 and overcoat 4, can be because of the increase of torsion, inner sleeve 3 and overcoat 4 all can produce resiliently deformable, and no longer be interlocking pattern this moment between the tooth, inner sleeve 3 can not moved again, and overcoat 4 can be because the increase of torsion can continue motion, when overcoat tooth 4.1 moves to inner sleeve tooth 3.1 again during interlocking pattern, resiliently deformable disappears, and can hear clear and melodious sound.So circulation just can be heard continuous tap-tap sound, tells the user to turn round and puts in place.Arrow is overcoat 4 sense of rotation among Fig. 9.
Above-mentioned is preferred version of the present utility model, and those of ordinary skills all drop within the protection domain of the present utility model its simple modification or transformation.
