Abstract
A fastener, belongs to technical field of fastening.Comprise bolt, nut, described bolt consists of head, the screw rod that is connected to head front, nut is connected with bolt thread, the head of described bolt is circular, it is characterized in that, connecting bolt and coupling nut that described screw rod is provided with screw, matches with screw, connecting bolt screws in screw and is threaded with coupling nut, and the head that screws in the connecting bolt in screw is placed in the lower end of nut; Described nut lateral wall is provided with raised line, and the circumference of nut upper end port is provided with annular flange flange.The utility model is simple and reasonable, manufactures easily, installs firmly, has the wide market space.
Description
Technical field
The utility model relates to a kind of structure of fastener, and especially a kind of fastener structure of the connection for toilet and toilet lid, belongs to technical field of fastening.
Background technology
Bolt, nut are the most frequently used securing members of people, and it is simple in structure, easy to use, respond well, are widely used in various occasions.Bolt, by head and screw rod (with an externally threaded cylinder) class securing member dimerous, need coordinate with nut, for being fastenedly connected two with the part of through hole.This type of attachment claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connects, be to belong to removably connect.When two union pieces are subject to larger vibrations, the connection of bolt, nut usually can produce loosening phenomenon, causes to connect and throws off.
Toilet is as a kind of articles for daily use, all appear at every day in people's life, toilet mainly consists of ladle body, water tank and toilet lid, and toilet lid is provided with two, with ladle body, the installing hole being connected is installed, and ladle body is also being provided with installing hole with toilet lid installing hole corresponding position.Toilet lid is raised, is closed many times every day, uses for a long time, and the connecting bolt between toilet and toilet lid is easy to become flexible, and causes to connect and throws off.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of fastener being firmly connected with toilet lid for toilet of installing is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of fastener, comprise bolt, nut, described bolt consists of head, the screw rod that is connected to head front, nut is connected with bolt thread, the head of described bolt is circular, it is characterized in that connecting bolt and coupling nut that described screw rod is provided with screw, matches with screw, connecting bolt screws in screw and is threaded with coupling nut, and the head that screws in the connecting bolt in screw is placed in the lower end of nut; Described nut lateral wall is provided with raised line, and the circumference of nut upper end port is provided with annular flange flange.
The diameter of described bolt head is 2.5-5cm.
Described spiro rod length is 5.5-10.0cm.
The thickness of described annular flange flange is 0.15-0.45cm.
The back side of described bolt head is provided with cross groove.
Between described bolt, nut, be provided with seal washer.
The back side of described connecting bolt head is provided with cross groove.
Connecting bolt and coupling nut that screw rod is provided with screw, matches with screw, screw is positioned at nut below, after bolt and nut are connected and fixed, connecting bolt is screwed in to the screw that is positioned at nut below, and be threaded with coupling nut, the head that screws in the connecting bolt in screw props up the lower end of nut, prevents screw cap-falling, affects being connected of toilet and toilet lid.Like this, even if being subject to large vibrations again, toilet lid can not affect the firm of toilet and toilet lid yet.
The utility model in use, two bolts are inserted in two installing holes on toilet lid and toilet ladle body successively, on screw rod, overlap upper sealing washer, nut successively, and the cross groove that utilizes cross driver to withstand the bolt head back side fixes bolt, thus tightening nuts (nut is had one end of flange positive towards bolt head).Finally connecting screw rod is screwed in screw, then the coupling nut of screwing on, guarantee that nut can be because of vibrations loose or dislocation.Annular flange flange can better be held seal washer, and the connection of strengthening stud, nut is conducive to being connected firmly of toilet lid and toilet ladle body, and four raised lines on nut lateral wall can strengthen the resistance between hand and nut, are convenient to tightening nuts and bolt.The diameter of bolt head is larger, and the adjustable distance between two bolts is larger.
The utility model is simple and reasonable, manufactures easily, installs firmly, has the wide market space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of nut in the utility model;
Fig. 3 is the structural representation at the bolt head back side in the utility model;
In figure: 1 nut, 2 bolt heads, 3 screw rods, 4 raised lines, 5 annular flange flange, 6 cross recess, 7 connecting bolts, 8 coupling nuts.
The specific embodiment
The fastener being connected with toilet lid for toilet, comprises bolt, nut 1, and bolt consists of head 2, the screw rod 3 that is connected to head front, between bolt, nut, is provided with seal washer.The head 2 of bolt is circular, and the diameter of bolt head is 2.5-5cm, and the back side of bolt head is provided with cross groove 6, and spiro rod length is 5.5-10.0cm.
Connecting bolt 7 and coupling nut 8 that screw rod 3 is provided with screw, matches with screw, connecting bolt screws in screw and is threaded with coupling nut, the head that screws in the connecting bolt in screw is placed in the lower end of nut, and the back side of connecting bolt head is provided with cross groove.
On nut 1 lateral wall, be provided with uniformly raised line 4, the circumference of nut upper end port is provided with annular flange flange 5, and thickness is 0.15-0.45cm.
Connecting bolt and coupling nut that screw rod is provided with screw, matches with screw, screw is positioned at nut below, after bolt and nut are connected and fixed, connecting bolt is screwed in to the screw that is positioned at nut below, and be threaded with coupling nut, the head that screws in the connecting bolt in screw props up the lower end of nut, prevents screw cap-falling, affects being connected of toilet and toilet lid.Like this, even if being subject to large vibrations again, toilet lid can not affect the firm of toilet and toilet lid yet.
