Abstract
The utility model relates to an anti-disassembly detachable dual-purpose expansion screw, which belongs to the field of fasteners. The anti-disassembly detachable dual-purpose expansion screw of the utility model is composed of a screw rod 1, an expansion sleeve pipe 2 and a conical nut 3. The utility model is characterized in that a backstop structure 4 of a combined type boss is arranged on the appropriate position on the front part of the screw rod 1. The utility model has the advantages of compact design and flexible operation, besides, the utility model can meet an anti-disassembly requirement according to specific mounting requirements; the utility model is a dual-purpose design. The exposed parts is less after installation, and the external shape is beautiful.
Description
Technical field
A kind of tamper of the utility model/removable dual-purpose setscrew belongs to fastener areas.
Background technique
When building was installed some facility, setscrew was widely used finding.As burglary-resisting window is installed, when netting the facility of the relative extended immobilization of this class, must select the setscrew of tamper for use,, should aspire for stability and some is installed to strengthen its safety reliability, when being convenient to the facility moved such as solar water heater again, then select removable setscrew more suitable.The setscrew of existing market roughly has two kinds: a kind of is to expose the nut setscrew, and its setscrew exposes partly more, and nut is disassembled easily; Another kind is built-in nut setscrew, and its profile is more attractive in appearance, but lead screw is withdrawed from easily.Therefore, these two kinds of setscrews itself do not possess the tamper function.
The model utility content
The purpose of this utility model provides a kind of tamper/removable dual-purpose setscrew, to realize both having given setscrew itself non-disconnectable function, can be converted into removable setscrew simultaneously again as required neatly and use.Technical solutions of the utility model are as follows:
A kind of tamper of the utility model/removable dual-purpose setscrew is made up of screw 1, expansion sleeve 2 and tapered cup nut 3, it is characterized in that there is combined type boss retaining structure 4 lead screw 1 anterior appropriate location.
The boss diameter of said combined type boss retaining structure is greater than the diameter of lead screw 1, less than the internal diameter of tapered cup nut 3.
Said combined type boss retaining structure is annular groove-toroidal ring structure, is made up of the annular groove 5 of lead screw 1 front portion and the elastic band 6 of corresponding external diameter.
Said combined type boss retaining structure is through hole-bolt structure, is made up of the radial direction through hole 7 of lead screw 1 front portion and the screw 8 or the pin of respective diameters.
When combined type boss retaining structure of the present utility model is annular groove-toroidal ring structure, after lead screw forward annular groove fit is installed ring, the tamper function is arranged promptly, and when not adding ring, then be removable structure.In like manner, the anterior radial direction through hole of lead screw when the screw of cooperation installation respective diameters or pin, promptly has the tamper function, when not adding screw or pin, then is removable structure.
The utility model design is succinct, uses flexibly, according to concrete installation needs, both can satisfy the tamper demand, can adapt to removable use again, is a kind of design of use convenient to both.It is less to expose part after the installation, the profile better appearance.

Embodiment
Now further specify the utility model and how to implement in conjunction with annular groove-ring retaining structure.
When using for satisfying tamper, in the forward annular groove 5 of the lead screw 1 that includes expansion sleeve 2, tapered cup nut 3, the elastic band 6 of packing into, this ring external diameter is greater than screw rod 1 diameter, less than tapered cup nut 3 internal diameters.The lead screw 1 that turns clockwise, tapered cup nut 3 can advance voluntarily, forces expansion sleeve 2 lower ends cracking to expand fastening into body of wall.At this moment counterrotating lead screw in any case 1, owing to be subjected to stopping of spring ring 6, tapered cup nut 3 can't come off from lead screw 1, and lead screw 1 just can not be passed through expansion sleeve 2 together with tapered cup nut 3, thereby a whole set of setscrew also can't take out from body of wall.As the elastic band of not packing into, promptly satisfy removable setscrew and use.The enforcement of through hole-screw retaining structure in like manner.
