Description
Technical field
The utility model relates to the fin of racing boat, relates in particular to the fin of detouchable racing boat.
Background technology
Racing boat is sportsman's a kind of hull of paddling of working direction dorsad, originates from Britain the 17th century to the mid-eighteenth century.Racing boat ship tail bottom is provided with fin, and fin is to hold damageable parts in racing boat, fixedly sticks on the ship tail but the fin of racing boat in the past is all direct non-disconnectable formula, and is very inconvenient when needs are changed fin.
Summary of the invention
technical problem to be solved in the utility model is to provide a kind of removable fin box for racing boat, for this reason, the utility model is by the following technical solutions: it comprises fin, described fin box also is provided with the mounting bar that is connected with the ship shell, described mounting bar has the groove that suitable fin inserts, before and after the top of described fin, both sides have front side bayonet slot and the rear side bayonet slot of fore-and-aft direction, have the front transverse bolt that is fit to front side bayonet slot and the rear transverse bolt that is fit to rear side bayonet slot in described groove, described fin inserts described groove, front transverse bolt crosses front side bayonet slot, rear transverse bolt crosses rear side bayonet slot, in the front portion of described fin, described fin box is provided with set screw, and described set screw is connected and blocks the front portion of fin with mounting bar.
Adopting on the basis of above technical scheme, the utility model also by the following technical solutions:
The length of described front side bayonet slot is greater than the length of rear side bayonet slot, and when described front transverse bolt contacted bottom front groove draw-in groove, described rear transverse bolt was deviate from rear side bayonet slot.
The both sides of described mounting bar have the draw-in groove that is connected with the ship shell.
Owing to adopting the technical solution of the utility model, realized the removable installation of fin, simple in structure, be connected firmly, and dismounting operation is very easy.
Description of drawings
Fig. 1 is for using the front view of racing boat of the present utility model.
Fig. 2 is decomposing schematic representation of the present utility model.
Fig. 3 installs the process schematic diagram of fin.
The specific embodiment
With reference to accompanying drawing, fin box provided by the utility model comprises that fin 1 is connected the mounting bar 2 that shell connects with ship, described mounting bar 2 has the groove 20 that suitable fin 1 inserts, before and after the top of described fin 1, both sides have front side bayonet slot 11 and the rear side bayonet slot 12 of fore-and-aft direction, have the front transverse bolt 21 that is fit to front side bayonet slot 11 and the rear transverse bolt 22 that is fit to rear side bayonet slot 12 in described groove 20, described fin 1 inserts described groove 20, front transverse bolt 21 crosses front side bayonet slot 11, and rear transverse bolt 22 crosses rear side bayonet slot 12; In the front portion of described fin 1, described fin box is provided with set screw 3, and described set screw 3 is connected the front portion that connects and block fin 1 with mounting bar.
The length of described front side bayonet slot 11 is greater than the length of rear side bayonet slot 12, and when front groove draw-in groove 11 bottoms contacted, described rear transverse bolt 22 was deviate from rear side bayonet slot 12 when described front transverse bolt 21.
The both sides of described mounting bar 2 have the draw-in groove 23 that is connected with ship shell 100.
With reference to figure 3, before first the front side bayonet slot 11 of fin being aimed at when mounted, transverse bolt 21 inserts, when front side bayonet slot 11 bottom is arrived on current transverse bolt 21 tops, rear side bayonet slot 12 can be in the inboard of rear transverse bolt 22, with fin after the pusher certain distance, make rear transverse bolt 22 bottoms push up rear side bayonet slot 12, then fin and mounting bar location are fixed in the front side with screw 3, thereby completed installation.Otherwise be detachable fin 1.
