Abstract
The utility model discloses a concave-convex embedded wall nail with displacement prevention function. The wall nail comprises a nail sleeve and a pin, wherein an inner hole for accommodating the pin is axially formed on the nail sleeve; a vertical opening extending axially is further formed on the nail sleeve; the end part of the nail sleeve is divided by the vertical opening to form an expansion arm; a plurality of protruding edges arranged around the circumferential direction of the expansion arm are arranged on the outer wall of the expansion arm in the length direction; the longitudinal section of each protruding edge adopts a trapezoid structure; one side of the protruding edge close to the top end of the expansion arm is shorter than the other side; a plurality of uniformly-distributed grooves are formed on the inner wall of the inner hole around the circumferential direction; and protruding teeth matched with the grooves are arranged on the outer wall of the pin around the circumferential direction. On the wall nail, the protruding teeth and the grooves both matched with each other are arranged on the pin and the inner hole, when the pin is screwed into the inner hole, the protruding teeth are inserted into the grooves, the grooves can stop the pin from performing transverse and axial displacement in the nail sleeve, the pin is more stably arranged in the inner hole and hard to slip, so that the construction service life is prolonged.
Description
Technical field
The utility model belongs to building material field, is specifically related to a kind of anti-displacement of concavo-convex mosaic wall nail that is used for exterior wall tile or decorative panel.
Background technology
Existing wall nail comprises nail cover and pin, during use, on the exterior wall tile of desire construction and body of wall, holes earlier; Be inserted in the hole of body of wall after the end with expansion arm passes exterior wall tile following closely to overlap; In the knock-in tack of will pinning the again cover, said pin top external diameter makes described expansion arm radially open greater than the aperture of nail cover; And the hole wall of stretching body of wall, so can exterior wall tile be fixed on the metope.Through for preventing that the wall nail from coming off from body of wall, follow closely to put disconnecting prevention structure can be set, such as on the expansion arm of nail cover, the tooth line is set; But after vibration or long-time the use; This pin easily loosening and in said nail cover the edge laterally or axially produce micro-displacement, make the radial-deformation of expansion arm diminish, hole wall that can't the stretching body of wall; And make and to close down landing from the body of wall, and cause the waste of constructional materials and the puzzlement that repeats to construct.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and the anti-displacement of a kind of concavo-convex mosaic wall nail is provided, and it can avoid pin in the nail cover, to produce laterally or axial displacement, has stronger steadiness.
The technical scheme that the utility model adopted is: the anti-displacement of a kind of concavo-convex mosaic wall nail; Comprise nail cover and pin; Said nail cover has the endoporus that is used to hold pin vertically; Said nail puts and also has the longitudinal opening that extends vertically, and the end of said nail cover is separately formed expansion arm by said longitudinal opening, and said expansion arm outer wall is provided with a few fins that is provided with around the expansion arm circumferencial direction along its length; Said fin longitudinal cross-section is trapezium structure; Its one side near the expansion arm top is shorter than another side, offers several evenly distributed grooves around circumferencial direction on the said endoporus sidewall, and said pin outer wall is provided with the double wedge that embeds coupling with above-mentioned groove around circumferencial direction.
As preferably, be provided with dowel between the said fin, and the longitudinal cross-section of said dowel also is trapezium structure, its one side near the expansion arm top is shorter than another side.
As preferably, the spacing between the said fin is reduced to its top by said expansion arm bottom successively.
The beneficial effect of the utility model is: be provided with fin at the expansion arm outer wall, and the fin longitudinal cross-section is trapezium structure, makes to contact between holing on nail cover and the body of wall more firmly, be difficult for deviating from; In addition, on pin and endoporus, be provided with the double wedge and the groove of mutual coupling, after pin is squeezed into endoporus; Double wedge is inserted in the groove, and said groove can stop the horizontal and axial displacement of pin in the nail cover, makes pin more firmly be arranged in the endoporus; Be difficult for slippage, so prolonged the construction life-span.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional view of Fig. 1.
Among the figure: 1, nail cover; 2, pin; 3, endoporus; 4, fin; 5, dowel; 6, groove; 7, double wedge; 8, longitudinal opening.
The specific embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explain below.
As depicted in figs. 1 and 2; The anti-displacement of a kind of concavo-convex mosaic wall nail comprises nail cover 1 and pin 2, and said nail cover 1 has the endoporus 3 that is used to hold pin 2 vertically; Also have the longitudinal opening 8 that extends vertically on the said nail cover 1; The end of said nail cover 1 was opened the formation expansion arm in 8 minutes by said longitudinal opening, and said expansion arm outer wall is provided with a few along its length around the fin 4 that the expansion arm circumferencial direction is provided with, and said fin 4 longitudinal cross-sections are trapezium structure; Its one side near the expansion arm top is shorter than another side; Spacing between the said fin 4 is reduced to its top by said expansion arm bottom successively, offers several evenly distributed grooves 6 around circumferencial direction on said endoporus 3 sidewalls, and said pin 2 outer walls are provided with the double wedge 7 that embeds coupling with above-mentioned groove 6 around circumferencial direction.As preferably, be provided with dowel 5 between the said fin 4, and the longitudinal cross-section of said dowel 5 also is trapezium structure, its one side near the expansion arm top is shorter than another side.
