Abstract
The utility model relates to a fastener used in a structure block of a building. The front part of the fastener is provided with a casing tube which is provided with an expansion opening. The utility model is characterized in that the casing tube has the front end with smaller inside-diameter and the rear part with larger inside-diameter; besides, the rear part is provided with inner screw-threads; a conical pin is arranged inside the casing tube; a nut sleeve is expanded and is fixedly hidden inside a wall, and a fastening bolt is a movably-screwing body. Therefore, according to the thickness of an object needed to be fixed and the requirements of decoration, any bolts can be selected for facilitating a beautiful appearance of the whole body, and the utility model has the advantages of reliable and firm positioning, flexible and convenient changing and no residual obstructer exposed outside.
Description
The utility model relates to a kind of fastening piece that is used for building masonry wall and other structure.
At present, when on body of wall or other structure, setting up object, adopt the fastening location of setscrew mostly.The use of setscrew is though bring great convenience to fitment operation.But because the screw rod of setscrew is fixed, once squeezing into body of wall, the thickness of its clamping will be subjected to the restriction of screw rod self length, and it comprises the exposed parts of part such as tightening nut, hinder whole appearance.When especially decorative article being installed, more make a nuisance of oneself.In addition, set up thing even removed, still remaining screw rod on the body of wall influences attractive in appearancely, has brought new challenge also for thus the use of setscrew.
The purpose of this utility model provides a kind of recessive type expanding nut cover.Its nut sleeve expands to be fixed in the body of wall and hides, and the clamping bolt that is mated connection is movable, and can match arbitrarily according to the needs of fixture.Not only firm position is reliable for it, and it is flexible to change the outfit, and noresidue exposes obstacle, does not influence overall appearance.
The purpose of this utility model is achieved in that it comprises that the front portion has the sleeve pipe of expansion notch, it is characterized in that the front inner diameter of expanding nut cover is less, and the rear portion internal diameter is bigger, and the rear portion is provided with internal thread, and is provided with the awl pin in sleeve pipe.
During use, earlier nut sleeve is placed in the body of wall, place the object that to fix then, cooperate with the bolts and nuts cover again and connect, and promote the small-caliber end that the awl pin moves forward to sleeve pipe thus, simultaneously the anterior distending of sleeve pipe is expanded in the body of wall content, thereby make it fastening location.
The utility model compared with prior art has following advantage:
Because expanding to be fixed in body of wall or other structure, its nut sleeve hides, and cooperate the bolt that connects with it is movable outer spinning body, therefore, when on body of wall or other structure, object being installed, can require to select the bolt that length is suitable, the nut profile matches according to the thickness and the decoration of fixation, as selecting bolts such as tack, countersunk head, hexagonal according to different needs, to reach the ornamental requirement of overall appearance.Time spent not can screw out bolt and fixation is driven remove, i.e. noresidue exposes obstacle, and can still utilize former nut sleeve as required, direct objects such as spinning suspension ring, hook, or change the outfit that other sets up thing, and do not need punching in addition to reinstall nut sleeve.Its transposing is used very convenient flexible; If the setscrew nut cover of establishing in no longer needing, then available coating is filled and led up porthole, and does not influence the smooth conformity of metope.Secondly, be provided with the back-off hook ring,, increase location intensity to increase area of contact in jacket exterior of the present utility model.In addition, it is little to be provided with the anterior diameter of two joints in nut sleeve, the awl pin that the rear portion diameter is bigger, thus further guaranteed the support distending degree of sleeve pipe, it is more solid and reliable to make it the location.
Fig. 1 is the utility model nut sleeve structural representation.
Fig. 2 is the side view of Fig. 1.
Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.
Referring to accompanying drawing, expanding nut cover of the present utility model comprises sleeve pipe 1, and sleeve pipe 1 front inner diameter is less, and the rear portion internal diameter is bigger, and the front portion has expansion notch 2, and the rear portion is provided with internal thread 3, and is provided with awl pin 4 in sleeve pipe 1.Awl pin 4 is that the anterior diameter of two joints is little, the awl pin that the rear portion diameter is bigger.In sleeve pipe 1 outer installment back-off hook ring 5 is arranged.
Claims (3)
1, a kind of recessive type expanding nut cover, it comprises that the front portion has the expansion sleeve of notch (2) (1), is characterized in that: sleeve pipe (1) front inner diameter is less, and the rear portion internal diameter is bigger, and the rear portion is provided with internal thread (3), and is provided with awl pin (4) in sleeve pipe (1).
