Description
[technical field]
The utility model relates to a kind of dust cover.
[background technique]
At present, the being seen mountable steel bridge of people generally is the girder frame by derrick tower Cheng Qiao, adopts panels of wood to be paved into the driving passage again, owing to need to adopt many panels of wood, is unfavorable for saving timber resources; Have the traffic capacity of this steel bridge poor again, current noise is big.People have designed a kind of U shaped steel bridge deck of mountable steel bridge at this situation, though these U shaped steel bridge deck solve above problem, but since bridge deck mostly by counterbore by bolt, therefore the dust that is produced during vehicle pass-through can be dispersed in the counterbore gradually, and this dust is easy to make bolt to get rusty through accumulation for a long time, and is difficult to change, in addition, because the bolt of fixed bridge panel must adopt the bolt of large size, therefore usually stolen, make steel bridge have certain potential safety hazard.
The utility model has carried out useful improvement with regard to above shortcoming.
[model utility content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of easy for installation, dustproof, antitheft dust cover is provided.
The purpose of this utility model is to realize like this;
A kind of dust cover, the bolt that is used on the steel bridge deck is dustproof, it is characterized in that comprising lid, is provided with the shrinkage pool that the bolt head with bolt is complementary on lid, is provided with holding tank in cover body outside.
Aforesaid a kind of dust cover is characterized in that described lid made by rubber.
The utility model compared with prior art has following advantage: because the utility model can tightly be enclosed within on the bolt head of bolt, therefore dust can not be penetrated on the bolt under the lid, played the dust-tight effect, in addition, the operator must just can change by elder generation's taking-up dust cover when changing bolt, dust cover then needs to cooperate the corresponding clamp of holding tank with the lid outside it could be taken out, because play antitheft effect.
[description of drawings]
Fig. 1 is a stereogram 1 of the present utility model;
Fig. 2 is a stereogram 2 of the present utility model.
[embodiment]
The utility model will be further described below in conjunction with accompanying drawing and embodiment:
A kind of dust cover, the bolt that is used on the steel bridge deck is dustproof, comprises lid 1, is provided with the shrinkage pool 2 that the bolt head with bolt is complementary on lid 1, is provided with holding tank 3 in the both sides of lid 1; Described lid 1 is made by rubber.
During installation, the operator only needs tightly being enclosed within on the bolt head in the counterbore of shrinkage pool 2 correspondences of lid 1 got final product.Because the utility model can tightly be enclosed within on the bolt head of bolt, therefore dust can not be penetrated on the bolt under the lid 1, played the dust-tight effect, in addition, the operator must just can change by elder generation's taking-up dust cover when changing bolt, dust cover then needs to cooperate the holding tank 3 corresponding clamps with the lid outside it could be taken out, because played antitheft effect.
