Abstract
An expansion screw with colloid comprises a bush, a screw and a colloid body. According to the expansion screw with the colloid, the screw is rotated to move inwards the bush, the sharp end pierces the colloid body outer membrane, the colloid body is extruded, flexible colloid is extruded into a gap between an internal thread and a screw thread, into a slit, into a gap between the screw and the inner walls of expansion pieces as well as space between the bush and the inner wall of a hole, the sharp end moves downwards continuously, the expansion pieces are extruded to expand outwards to be full of the whole hole, then the bush cannot be drawn out, meanwhile, a fixed piece is pressed by a screw head, the colloid is solidified after a period of time, and the expansion screw is cured in the hole. The expansion screw has the advantages of simple structure, convenience in use and operation, wide use range and good fixing effect.
Description
Technical field
The present invention relates to a kind of setscrew, especially can be solidificated in the setscrew in body of wall.
Background technique
At present, general setscrew, one, screw is screw thread, one is vertebra degree, outer bread one iron sheet, and iron sheet cylinder half has some otch, after mounting article, there is certain space between screw thread place and iron sheet cylinder, can rock, be generally used for fastening on the material such as cement, brick such as protective grating, rain cover, air-conditioning, but its is fixing very unreliable, if load has comparatively big bang, may getting loose, therefore not recommending for installing ceiling fan etc.; General setscrew is only at the large limit extruding iron sheet of vertebra degree, and the overstocked distortion of iron sheet is certain, and the surface friction drag of generation is limited, and load is excessive also should not be used.Hammering type EXPANSION ANCHOR BOLTS is followed closely by lining and hammering and is formed, the front end of lining is the bulge offering some the centrally lines of rabbet joint of axial direction, lining centrally axial direction be provided with an accommodating hammering nail place trunk, place trunk and the bulge place of lining is provided with a closed end mated with the propelling end that hammering is followed closely, the lining distortion of hammering type EXPANSION ANCHOR BOLTS is certain, the surface friction drag produced is limited, and load is excessive should not be used; And there is certain space in the hole on screw thread place and wall, can rocking, if load has comparatively big bang, may get loose, therefore not recommending for installing ceiling fan etc.; If the hardness of body of wall is very large, the closed end be difficult to through lining is followed closely in hammering, and now hammering nail can retreat at any time and come off.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of and can be solidificated in body of wall and the setscrew of band glue, this device have structure simple, use easy to operate, using scope wide, the advantage of good fixing effect.
For achieving the above object, technical solution of the present invention is:
Setscrew with glue is made up of lining, screw, colloid, rotary screw is followed closely, screw moves in lining, tip punctures colloid adventitia, extruding colloid, flexible glue is squeezed between internal thread and screw screw thread, space in the line of rabbet joint, between screw and intumescent sheet inwall, between lining and hole inwall, tip continues to move down, extrusion expansion sheet outwards expands, the whole hole of overflow, lining just can't pump out, and fixture pushed down by ailhead simultaneously, gelling is after a period of time solid, and such setscrew is just cured in hole.
The invention has the beneficial effects as follows:
Structure is simple: be made up of lining, screw, colloid.
Use easy to operate: first the lining with colloid is firmly filled in hole, then screw is penetrated in fixed block, finally, screw is rotated into lining.
Using scope is wide: can be used for fastening on the material such as cement, brick such as protective grating, rain cover, air-conditioning, and also may be used for load has object compared with big bang, and as installed ceiling fan etc., and the fixing of larger load also can be applied.
Good fixing effect: after gelling is solid, setscrew is just cured in hole.

Embodiment
As shown in Figure 1, the inner-spiral type setscrew of band glue is made up of lining (1), screw (8), colloid (13), and colloid (13) is bottom in lining (1), and screw (8) is rotated in lining (1); Lining top (7) inner face has internal thread (2), lining (1) bottom is divided into polylith intumescent sheet (4) by the line of rabbet joint (3), polylith intumescent sheet (4) is slightly towards separately outer, and the bottom of intumescent sheet (4) is most advanced and sophisticated (6), is friction belt (5) in the top of most advanced and sophisticated (6); The upper end of screw (8) is ailhead (9), and the middle-end of screw (8) is screw thread (11), and the lower end of screw (8) is nail tip (10); Colloid (13) is made up of flexible glue (14) and colloid adventitia (15), colloid adventitia (15) parcel flexible glue (14).
As shown in Figure 2, in A, in body of wall (16), make a call to a hole (17); In B, the lining (1) with colloid (13) is firmly filled in hole (17) mouth, hole (17) mouth extruding most advanced and sophisticated (6), most advanced and sophisticated (6) inwardly shrink; In C, the lining (1) with colloid (13) is stuffed in hole (17), intumescent sheet (4) bounce-back extruding hole (17) inwall.
As shown in Figure 3, in D, screw (8) penetrates fixture (12), then screw (8) is rotated into lining (1); In E, screw (8) continues to be rotated down, and nail tip (10) punctures the colloid adventitia (15) of colloid (13), and flexible glue (14) is extruded; In F, screw (8) continues to be rotated down, and flexible glue (14) continues to be extruded, and flexible glue (14) is squeezed between internal thread (2) and screw screw thread (11), space in the line of rabbet joint (3), between lining (1) and hole (17) inwall; In G, screw (8) continues to be rotated down, flexible glue (14) continues to be squeezed between internal thread (2) and screw screw thread (11), space in the line of rabbet joint (3), between lining (1) and hole (17) inwall, most advanced and sophisticated (6) continue to move down, and overstock intumescent sheet (4) simultaneously and outwards expand, the whole hole of overflow, now, lining (1) just can't pump out, and meanwhile, fixture (12) pushed down by ailhead (9).
As shown in Figure 4, flexible glue (14) be squeezed between internal thread (2) and screw screw thread (11), space in the line of rabbet joint (3), between screw (8) and intumescent sheet (4) inwall, between lining (1) and hole (17) inwall.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
