Abstract
The utility model discloses a waterproof construction that couple and screw that is used for photovoltaic board to install, its technical essential is that the through -hole has been seted up including the bottom plate to the couple on including couple and screw, during the through -hole is worn to locate by the screw, characterized by: the screw includes head and pole portion, the lower edge of head is provided with waterproof preforming, be provided with waterproof gasket in the pole portion, the diameter of waterproof gasket and waterproof preforming all is greater than the aperture of through -hole. The utility model provides a prevent that the rainwater from entering into a waterproof construction that couple and screw that is used for photovoltaic board to install of the through -hole on the bottom plate.
Description
Technical field
This utility model relates to a kind of hook installed for photovoltaic panel and the waterproof construction of screw.
Background technology
Along with the development of solar-photovoltaic technology, solar energy power generating is widely used.Can use hook and guide rail on roof when solar photovoltaic assembly is installed, the side i.e. linked up with is fixed on roof, and the opposite side of hook connects guide rail, and last guide rails assembling is on guide rail.In prior art, hook, when being connected with roof, is all to offer through hole on hook, wears bolt the most in through-holes, and be screwed in roof by bolt, realize the connection on hook and roof with this.Yet with the defective tightness of laminating between through hole and bolt, there is space the most between the two, during so running into the rainy day, rainwater is easily advanced in space between the two, and enter into inside roof, even can cause the situation that roof leaks, therefore there is the space of improvement.
Utility model content
For the deficiencies in the prior art, this utility model provides the hook installed for photovoltaic panel in a kind of through hole preventing rainwater from entering on base plate and the waterproof construction of screw.
For achieving the above object, this utility model provides following technical scheme:
A kind of hook installed for photovoltaic panel and the waterproof construction of screw, including hook and screw, hook includes base plate, through hole is offered on base plate, screw is arranged in through hole, it is characterized in that: described screw includes head and bar portion, and the lower edge of described head is provided with waterproof tabletting, being provided with waterproof gasket in described bar portion, the diameter of described waterproof gasket and waterproof tabletting is all higher than the aperture of through hole.
Pass through technique scheme, in bolt penetrates into through hole, and when screwing, waterproof gasket can be played the effect of air pressure by waterproof tabletting, waterproof gasket is fitted between waterproof tabletting and base plate closely, thus is effectively prevented the situation that rainwater enters in through hole.
Preferably, described waterproof tabletting and waterproof gasket are the most in the form of annular discs.
By technique scheme, when this setting can make bolt tighten, waterproof tabletting and waterproof gasket can be simultaneously worked as the effect of extruding so that waterproof tabletting and waterproof gasket deform upon, thus can play effective waterproof action, can play again the effect of buffering.
Preferably, described waterproof tabletting welds or integrally forges the lower edge in head, and described waterproof gasket is socketed on bar portion.
By technique scheme, this setting both can guarantee that the structural strength between waterproof tabletting and head, can facilitate again the dismounting of waterproof gasket.
Preferably, described waterproof gasket is that elastomeric material is made.
By technique scheme, plasticity and the waterproof effect of elastomeric material are preferable.

Detailed description of the invention
The hook installed this utility model for photovoltaic panel by Fig. 1 to Fig. 3 and the waterproof construction of screw are further described.
A kind of hook installed for photovoltaic panel and the waterproof construction of screw, including linking up with 1 and screw 2, hook 1 includes base plate 11, through hole 111 is offered on base plate 11, screw 2 is arranged in through hole 111, and described screw 2 includes that head 21 and bar portion 22, the lower edge of described head 21 are provided with waterproof tabletting 211, being provided with waterproof gasket 3 in described bar portion 22, the diameter of described waterproof gasket 3 and waterproof tabletting 211 is all higher than the aperture of through hole 111.
Further, described waterproof tabletting 211 and waterproof gasket 3 are the most in the form of annular discs, and offer connecting hole on waterproof gasket 3 center, by this connecting hole, waterproof gasket 3 are connected on screw 22.
Further, described waterproof tabletting 211 welds or integrally forges the lower edge in head 21, and described waterproof gasket 3 is socketed on bar portion 22.
Further, described waterproof gasket 3 is made for elastomeric material.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
