Abstract
The utility model discloses a looseness-proof and dustproof structure for an exposed screw, the connected piece is provided with a countersink hole, which is connected via a screw, the countersink hole is provided with a ring groove, the plastic cover is composed by a cover head and an embedded sleeve, the embedded sleeve is provided with a circular hook, the embedded sleeve is embedded into the countersink hole and abuts against the head of screw, and is clamped into the ring groove via a circular hook, the cover head completely seals the countersink hole from the outside. The looseness-proof and dustproof structure in the utility model is advantaged by adopting the plastic cover of low cost to seal the countersink hole, preventing dust and rust, also, preventing the screw from withdrawing to the outside, as well as looseness prevention, simple structure, and convenient use.
Description
Technical field
The utility model relates to the mounting structure of fastening piece, especially locking, the dustproof construction of the exposed screws of counter sink structure.
Background technique
Screw connects often employing counter sink structure, many screws that expose connect, be exposed in the more abominable Environmental Conditions, the screw corrosion, the influence dismounting, and reasons such as vibration cause loosening easily, and simple anti-loose structure can not solve the problem that screw gets rusty, and perhaps are subjected to the restriction of conditions such as complex structure.
The model utility content
The purpose of this utility model is: provides a kind of exposed screws locking dustproof construction, solves the problem that above-mentioned prior art exists, and not only locking but also dustproof antirust, simple in structure.
The locking dustproof construction of exposed screws of the present utility model, connected piece is provided with counter sink, connect with screw, its counter sink is provided with annular groove, vinyl cover is made of headkerchief and embedding cover, embeds cover and is provided with loop-hook, embeds to overlap to embed in the counter sink to approach screw head, and stick in the annular groove with loop-hook, headkerchief is sealed counter sink from the outside fully.Headkerchief is sealed counter sink fully, prevents that dust, water, air from entering, and avoids the screw corrosion, embed the stuck screw that stops of cover and withdraw from because of loosening in counter sink, play locking effect, vinyl cover is cheap, as disposable use element, pry open vinyl cover during dismounting, just can twist screw.
The utlity model has following advantage: adopted vinyl cover with low cost to seal counter sink, dustproof antirust, simultaneously, stop screw outwards to withdraw from, locking, simple in structure, use very convenient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the locking dustproof construction schematic representation of exposed screws of the present utility model.
Embodiment
Referring to accompanying drawing 1, the locking dustproof construction of exposed screws of the present utility model, part 1,2 interconnect, outside part 1 is provided with counter sink 11, connect with screw 3, counter sink 11 is provided with annular groove 12, and vinyl cover 4 is made of round headkerchief 43 and embedding cover 41, embed cover 41 and be provided with loop-hook 42, utilize the elasticity of plastics, embed in the embedding counter sink 11 that overlaps 41 interference and approach screw head, and stick in the annular groove 12 with loop-hook 42, vinyl cover 4 is just fully stuck, can not withdraw from unless destroy, also just stop screw 3 to withdraw from, play locking effect because of loosening, headkerchief 43 is sealed the exterior edge face 13 of counter sink 11 from the outside fully, prevents dust, water, air enters.
Claims (1)
