Abstract
The utility model discloses a nut structure capable of being quickly assembled and disassembled, which comprises a fixed frame, a nut sleeve, a movable piece and an elastic piece, wherein the fixed frame is preassembled in an installing hole; the nut sleeve is longitudinally connected with the fixed frame in a sleeving and sliding manner; at least one conical cavity is formed in the nut sleeve, and the transverse dimension of the cavity gradually increases from top to bottom; threads and a guide groove are formed in the movable piece, and the fixed frame penetrates through the guide groove, so as to enable the movable piece to be movably assembled in the cavity; the elastic piece is propped against between the movable pieces and the fixed frame. The nut structure has the following advantages: as the fixed frame is matched with the movable piece through the guide of the guide groove, and the movement of the movable piece in the cavity is limited, the phenomenon that a bolt cannot normally penetrate through during the installation because the movable piece moves in the cavity during the operation is avoided, therefore, the stability of product functions is improved; in addition, through the nut structure, the normal installation of installing seats with different thicknesses can be ensured; during the installation, the bolt can be quickly positioned to an installing position and can be in threaded connection with the threads of the movable piece without rotating for multiple circles, so that the time is saved, the efficiency is high, and the installation is quick.
Description
Technical field
The utility model relates to a kind of nut structure of fast assembling-disassembling.
Background technology
It is to be connected by bearing, bolt, pad and nut assembly that traditional closestool cover is connected with the installation of toilet ceramics seat, when flap is installed, first bolt is passed down through to the adjustment hole of bearing and passes the installing hole on ceramics seat, then below ceramics seat, pad is inserted in to bolt, again with spanner or manually nut is screwed on to bolt and tightens, make nut compress gasket, the bearing of flap is fixedly connected on ceramics seat.The problem that this traditional flap mounting means exists is: the narrow space at toilet ceramics seat rear, pad is placed on bolt, need nut rotation for a long time could make pad be stuck in installing hole lower surface with bolt tightening, therefore, the dismounting of nut, pad and bolt is wasted time and energy, and the installation and removal of flap are very inconvenient.

In the present embodiment, elastic component 400 side and between two card arms 521, elastic component 400 contacts are between movable part 300 and chassis 530 under movable part 300, when elastic component 400 distortion, 521 pairs of elastic components 400 of two card arms lead.
In the present embodiment, the bottom of elastic component 400 is resisted against in bulge loop 532, and the top of elastic component contacts mutually with limiting section 330, and bulge loop 530 and limiting section 330 are spacing for elastic component 400 is carried out, to limit its radial displacement.
In the present embodiment, bolt 600 passes fixed mount and nut sleeve 200 and coordinates with the screw thread bolt of movable part 300.
When this nut structure is installed, only need first two movable parts 300 be packed in cavity 210, the limiting section 330 at movable part 300 by elastic component 400 one end contacts again, the other end is resisted against in the bulge loop 532 in chassis 530, chassis 530 and nut sleeve 200 are slidably socketed mutually by chute 221 and being slidably matched of slide block 510, now elastic component 400 is limited between chassis 530 and movable part 300 again.Then, bottom surface by the end face contact of nut sleeve 200 at mount pad, again by the card arm of fixed mount 521 through installing hole 110 stretch in through hole 230, again through the gathering sill 310 of movable part 300 and stretch out through hole 230, and by draw-in groove 522, coordinate with the clamping of buckle 531 card arm 521 and chassis 530 be connected.Completed the prepackage of nut structure.When installing card arm 521, if mount pad thickness is thicker, only chassis 530 upwards need be promoted so that draw-in groove 522 and buckle 531 clampings, now the boss 523 of body 520 abuts against the top end face of installing hole 110, realizes the installation of nut structure on thicker mount pad; Also, this nut structure can carry out self-control according to the thickness of mount pad, is not subject to the restriction of mount pad thickness.
During construction bolt 600, only bolt 600 successively need be contacted with movable part 300 through perforation the 524, second through hole 240, because the distance between two movable parts under the effect at elastic component 400 is narrower, bolt 600 cannot pass, bolt 600 while stretching into, drives two movable parts 300 to move downwards downwards and outwards so that the spacing between two movable parts 300 becomes large, as shown in Figure 5 and Figure 6; Bolt 600 continues to move down until installation site, then screws bolt 600 and make it to enter between two movable parts and with the screw thread bolt of two movable parts and coordinate, and has just completed the locking of bolt, as shown in Figure 7 and Figure 8.
While needing demounting bolt, only need opposite spin bolt until the screw thread of bolt and movable part is separated.Dismounting fast, conveniently.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
