Abstract
The utility model relates to a fastening piece for general components or mechanical components, which comprises a nut core, wherein, bottom of a platy body of the nut core and upper end of the core pin are integral, and the platy body is provided with a central axle hole for inserting the bolt; at least a nut sheet, whose inner side is provided with screw threads, and outside is provided at least an inclined plane matched with the inclined plane of the core pin of the nut core, and the nut sheet is arranged in the nut core; a nut sleeve, wherein, a cavity matched with the core pin of the nut core is arranged in the nut sleeve, and a guide groove matched with the nut sheet is arranged in the cavity. If rapid dismounting is needed, the nut sleeve will be unscrewed, and a certain distance between the nut sleeve and the nut core is needed, which produces a clearance between the nut core and the nut sheet. When the nut sleeve is pulled downwards, the nut sheet will move off the bolt axially, which separates the screw threads or screw teeth of the nut sheet form the bolts; and then the nut is pull downwards again, the rapid dismounting of the nut will be realized. The utility model is suitable for the fastening of a plurality of components or mechanical components, such as the support of the cover plate of the toilet.
Description
(1) technical field
The utility model relates to the fastening piece that a kind of general member or machine element are used.
(2) background technique
Nut is a kind of widely used fastening piece that is used for general member or machine element, difference according to its application, nut has various structural type, for example common hexagon nut, forms whole series but the nut that can separate easily, the nut that is out of shape when fastening etc.The all threaded or thread of nut commonly used, the shortcoming of existing most nuts are can't quick-acting and quick-discharging, for example for the health of environment and the health of health, need often to clean the cover plate of water closet, owing to can not quick-acting and quick-discharging, cause a lot of inconvenience.
(3) summary of the invention
But the utility model aims to provide a kind of nut of quick-acting and quick-discharging.
The utility model is provided with 1 nut core, and nut core comprises the core bar on tabular body and band inclined-plane, and the upper end of tabular body bottom surface and core bar fuses, but tabular body is provided with the central shaft hole that is used for inserting bolt;
At least 1 nut sheet, nut sheet inboard be provided with can with the screw thread or the thread of clamping bolt engagement, the outside is provided with at least 1 section inclined-plane that cooperates with nut core core bar inclined-plane, the nut sheet places in the nut core.
1 nut sleeve is provided with the cavity that matches with the core bar of nut core in the cover, be provided with the guiding groove that cooperates with the nut sheet in cavity.
Said nut core tabular body can be rounded.
Core bar side in nut core can be established uncinus, and the upper end of uncinus and the tabular body of nut core fuse, and are provided with the groove that matches with uncinus on nut sleeve.
Said nut sheet mainly moves in the direction perpendicular to the axle center, preferably establishes a pair of nut sheet that symmetry is placed, and two sections are preferably established on the inclined-plane, the outside of said nut sheet.
Said nut core can have a section to move at axial direction.
During use, if need fast-assembling, then
1) when nut core is separated in the axial direction with nut sleeve, push away on being enclosed within nut sleeve on the bolt, when nut core was run into obstacle, push nut cover in the continuation compressed nut sleeve and nut core.By the extruding of the inclined-plane on nut core nut sheet, the nut sheet is moved toward axis direction simultaneously, screw thread on its screw thread or thread and the bolt or thread engagement, when screwing nut sleeve like this, nut sheet and bolt are tightly locked.
2) when nut core is close to nut sleeve, push away on fast on the bolt, the screw thread on the bolt or the inclined-plane of thread promote the inclined-plane of nut sheet screw thread or thread, make inclined-plane on the nut sheet promote nut core and move in the axial direction, and nut core is separated with nut sleeve.When nut core is run into obstacle, push nut cover in the continuation, nut sleeve and nut core are compressed, simultaneously by the extruding of the inclined-plane on nut core nut sheet, the nut sheet is moved toward axis direction, screw thread on its screw thread or thread and the bolt or thread engagement, when screwing nut sleeve like this, nut sheet and bolt are tightly locked.
If need quick-release, then unscrew nut sleeve, nut sleeve and nut core promptly produce certain distance, make between nut core and nut sheet and produce the gap.When drop-down nut sleeve, the nut sheet moves axially toward departing from bolt, and the screw thread of nut sheet or thread are separated with screw thread or thread on the bolt, during drop-down again nut, has promptly realized the function of nut quick-release.
The utility model is fastening applicable to a lot of members or machine element, for example the bearing of pan closet lid.
(4) description of drawings
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 2 is a principle schematic of the present utility model.Wherein (a) is the nut releasing orientation, (b) is the fast process of assembling of nut, (c) for the nut check state, is nut quick-release process (d) and (e).
(5) embodiment
As shown in Figure 1, the utility model is provided with nut core 1, a pair of nut sheet 2 and nut sleeve 3.Nut core 1 comprises the core bar 13 on circular body 11 and band inclined-plane 12, and circular body 11 is provided with the central shaft hole 14 that is used for inserting clamping bolt, is provided with vertical uncinus 15 at the side of core bar 13.Be provided with in the inboard of arc nut sheet 2 can with the thread 21 of clamping bolt engagement, the outside is provided with 2 sections inclined-planes 22,23 that cooperate with nut core core bar 13 inclined-planes 12.Be provided with the cavity 31 that matches with the core bar 13 and the nut sheet 2 of nut core in the nut sleeve 3, in cavity, be provided with the guiding groove that cooperates with the nut sheet, and the groove 32 that matches with the uncinus 15 of nut core.
In Fig. 2, (referring to Fig. 2 (a)) upwards pushes away nut sleeve 3 when being in the nut releasing orientation, screws nut sleeve toward screwing direction simultaneously.In the fast process of assembling of nut (referring to Fig. 2 (a) and (b)), when screwing nut sleeve 3, make nut core 1 gland nut sheet 2, the engagement of the thread of nut sheet and bolt 4 threads screws nut sleeve more, makes nut sheet hold-down bolt more, make simultaneously nut sleeve and nut core near.When nut sleeve, nut core and nut sheet closely cooperated, nut screwed (referring to Fig. 2 (c)).In nut quick-release process, when loosening nut sleeve, nut sleeve is separated (referring to Fig. 2 (d), (e)) with nut core, when nut sleeve and nut core are separated to certain distance (making the nut sheet that enough outer spaces of moving be arranged), the thread of drop-down nut sheet breaks away from the thread of bolt, nut can be easily drop-down, realizes the quick-release purpose.
Nut sheet of the present utility model cooperates by the inclined-plane with nut core, the nut sheet mainly is that the direction in vertical central moves, at axial direction a spot of moving can be arranged, and moving between nut core and nut sleeve mainly is axial moving, a spot of moving can be arranged in a circumferential direction.
